Abstract

A mounting support device allows workpieces to be attached at points intermediate between discrete positions of fixture bases of machine tools. The mounting support device has three support members. A lower support member is slidably attached to an intermediate member allowing the intermediate member to move along an x-axis. An upper support member is slidably attached to the intermediate member allowing the upper member to move along a z-axis. A jig for holding a workpiece is connected to the upper member. The lower support member is attached to the fixture base in a discrete location in the usual way. Thus, the jig holding the workpiece can be positioned intermediately between discrete mounting positions of the fixture base. The sliding attachments maintain precise alignment between the support members and can be secured after adjustment.

Claims

1. A mounting support device for securing a jig to a fixture base, said fixture base having means for attaching a member in discrete locations on said fixture base, comprising:

a first support member;

a second support member;

a third support member;

means for attaching said first support member in one of said discrete locations on said fixture base;

first means for slidably mounting said second support member on said first support member so that said second support member slides along an x-axis;

said x-axis being in fixed relation to said first support member;

second means for slidably mounting said third support member on said second support member, so that said third support member slides along a z-axis, said z-axis being substantially perpendicular to said x-axis;

first securing means for selectively fixedly securing said second support member to said first support member;

second securing means for selectively fixedly securing said third support member to said second support member;

a first securing by said first securing means being independent of a second securing by said second securing means, whereby said first support member is slidable with respect to said second support member when said second support member is fixedly secured to said third support member;

said first securing being independent of said second securing, whereby said third support member is slidable with respect to said second support member when said second support member is fixedly secured to said first support member; and

means for fixing said jig to said third support member;

said first means for slidably mounting including;

a first alignment surface of one of said first support member and said second support member;

said first alignment surface being parallel to said x-axis;

a first alignment member of another of said first support member and said second support member;

said first alignment member having means for aligning said first alignment member with respect to said first alignment surface when said first alignment member is urged toward said first alignment surface;

said first alignment member being connected to said another of said first support member and said second support member so that said first alignment member maintains a fixed alignment with said another of said first support member and said second support member; and

first means for urging said first alignment member against said first alignment surface, whereby motion of said second support member is restricted to sliding parallel to said x-axis.

2. The device as in claim 1, wherein said means for attaching a said first support member includes a reference hole and a reference hole pin insertable in said reference hole.

3. The device as in claim 1, wherein said means for attaching includes a plurality of reference holes and a reference hole pin insertable in any one of said plurality reference holes.

4. The device as in claim 1, wherein said means for attaching includes:

at least one reference slot having a T shape

a T-slot nut for receiving a reference slot screw;

said first support member having a mounting hole; and

said reference slot screw being insertable through said mounting hole to threadably engage said T-slot nut.

5. The device as in claim 1, wherein said second means for slidably mounting further comprises:

a second alignment surface of one of said second support member and said third support member;

said second alignment surface being parallel to said z-axis;

a second alignment member of another of said second support member and said third support member;

said second alignment member having means for aligning said second alignment member with respect to said second alignment surface when said second alignment member is urged toward said second alignment surface;

said second alignment member being connected to said another of said second support member and said third support member so that said second alignment member maintains a fixed alignment with said another of said second support member and said third support member; and

second means for urging said second alignment member against said second alignment surface, whereby motion of said third support member is restricted to sliding parallel to said z-axis.

6. The device as in claim 1, wherein said first means for urging includes a resilient member between said first alignment member and said another of said first support member and said second support member.

7. The device as in claim 5, wherein said second means for urging includes a resilient member between said second alignment member and said another of said second support member and said third support member.

8. The device as in claim 1, further comprising a first graduated scale on one of said first support member and said second support member for indicating a first selected position of said second support member relative to said first support member.

9. The device as in claim 8, further comprising a second graduated scale on one of said second support member and said third support member for indicating a second position of said third support member relative to said second support member.

10. The device as in claim 1, further comprising a graduated scale on one of said second support member and said third support member for indicating a position of said third support member relative to said second support member.

11. The device as in claim 1, wherein said first securing means further comprises:

a first set screw;

said another of said first support member and said second support member including a first threaded set screw hole;

said first set screw being threadably inserted in said first threaded set screw hole; and

said first set screw hole being positioned in said another of said first support member and said second support member such that said first set screw further urges said first alignment member against said first alignment surface to fix said second support member in said first selected position relative to said first support member.

12. The device as in claim 11, wherein said second securing means further comprises:

a second set screw;

said another of said second support member and said third support member including a second threaded set screw hole;

said second set screw being threadably inserted in said second set screw hole; and

said second set screw hole being positioned in said another of said second support member and said third support member such that said second set screw further urges said second alignment member against said second alignment surface to fix said third support member in said second selected position relative to said second support member.

13. The device as in claim 1, wherein said second securing means further comprises:

a set screw;

said another of said second support member and said third support member including a threaded set screw hole;

said set screw being threadably inserted in said set screw hole; and

said set screw hole being positioned in said another of said second support member and said third support member such that said set screw further urges said second alignment member against said second alignment surface to fix said third support member in said second selected position relative to said second support member.
