Abstract

A positioning block for positioning an object on a work bench includes a body having a positioning hole defined therethrough and a first bolt extends through the positioning hole. A support portion is formed on one side of the body and has a horizontal surface and an upright surface. A flange extends from the body and the board is pressed on the flange. The horizontal surface is parallel to the bottom face of the body. An angle is defined between the horizontal surface and the upright surface.

Claims

1. A positioning block comprising:

a body having a positioning hole defined therethrough and a first bolt extending through the positioning hole, a support portion formed on a side of the body and having a horizontal surface and an upright surface, the horizontal surface being parallel to a bottom face of the body, an angle defined between the horizontal surface and the upright surface.

2. The block as claimed in claim 1, wherein the positioning hole is replaceable by a flange extending from the body.

3. The block as claimed in claim 1, wherein the angle defined between the horizontal surface and the upright surface is 90 degrees, a groove is defined in a connection portion between the horizontal surface and the upright surface.

4. The block as claimed in claim 3, wherein a front threaded hole is defined in a front face of the body, a second bolt extends through an adjustment member and is threadedly connected to the front threaded hole so as to fix the adjustment member to the front face, the adjustment member is movable adjacent to one side of the horizontal surface of the support portion.

5. The block as claimed in claim 4, wherein the body has a positioning slot and a first block is located in the positioning slot.

6. The block as claimed in claim 5, wherein the body has a top threaded hole defined in a top face thereof, a third bolt is threadedly connected to the top threaded hole by a threaded section thereof.

7. The block as claimed in claim 2, wherein the body has a guide passage defined therein and a rod of the adjustment member slidably received in the guide passage, a threaded hole is defined in a top face of the body and communicates with the guide passage, the adjustment member has a stop and the rod extends from the stop which is located at one end of the support portion, a locking member is threadedly connected to the threaded hole of the body and reaches an interior of the guide passage so as to contact and position the rod of the adjustment member.

8. The block as claimed in claim 7, wherein the rod of the adjustment member has a threaded section extending from an end thereof, the threaded section is threadedly connected to an inner threaded hole of the adjustment member to connect the rod and the stop.

9. The block as claimed in claim 7, wherein the rod of the adjustment member and the guide passage are engaged with each other by way of protrusion-and-recess.

10. The block as claimed in claim 8, wherein the rod of the adjustment has a surface against which the locking member contacts.

11. The block as claimed in claim 10, wherein the surface of the rod of the adjustment has scales marked thereon.

12. The block as claimed in claim 11, wherein the angle defined between the horizontal surface and the upright surface is 90 degrees, a groove is defined in a connection portion between the horizontal surface and the upright surface, the body 5 has a top threaded hole defined in a top face thereof and a third bolt is threadedly connected to the top threaded hole.
