Abstract

A mechanism, configured for positioning a work piece, includes a support member and a position assembly. The position assembly includes a guiding member and a positioning sleeve sleeved on the guiding member. The guiding member detachably is coupled to the support member. The positioning sleeve is detachably coupled to the support member. The guiding member is partially exposed from the positioning sleeve.

Claims

1. A mechanism for positioning a workpiece, the mechanism comprising:

a support member; and

a position assembly comprising;

a guiding member detachably coupled to the support member, and

a positioning sleeve sleeved on the guiding member and detachably coupled to the support member;

wherein, the guiding member is partially exposed from the positioning sleeve.

2. The mechanism of claim 1, wherein the guiding member is threaded with the support member to adjust an exposing length of the guiding member exposing from the positioning sleeve.

3. The mechanism of claim 2, wherein the support member defines a mounting hole, the support member has an inner thread received in the mounting hole, the guiding member comprises a thread rod, the threaded rod is threaded with the inner thread.

4. The mechanism of claim 3, wherein the guiding member further comprises:

a limiting block coupled to the threaded rod, a width of the limiting block larger than a diameter of the thread rod, and

a pin coupled to the limiting block and partially exposed from the positioning sleeve.

5. The mechanism of claim 4, wherein the positioning sleeve axially defines a receiving hole, the receiving hole comprises a first receiving portion, a second receiving portion communication with the first receiving portion, and a third receiving portion communication with the second receiving portion, the support member is received in the first receiving portion, the guiding member is received in the second receiving portion and the third receiving portion, the pin is partially exposed from the third receiving portion.

6. The mechanism of claim 5, wherein a diameter of the third receiving portion is smaller than a diameter of the second receiving portion, a restriction portion is formed between the second receiving portion and the third receiving portion, the restriction portion is configured to restrict the exposing length of the guiding member exposing from the positioning sleeve.

7. The mechanism of claim 6, wherein the limiting block is substantially cuboid, the second receiving portion is substantially a cuboid hole, a sectional size of the second receiving portion matches a sectional size of the limiting block, a height of the second receiving portion is larger than a height of the limiting block, the limiting block is configured to slide along the second receiving portion.

8. The mechanism of claim 1, wherein a fastener is detachably couple the positioning sleeve and the support member.

9. The mechanism of claim 1, wherein the positioning sleeve is made of ceramic.

10. The mechanism of claim 1, wherein the guiding member is made of plastic.

11. The mechanism of claim 1, wherein the positioning sleeve has a conical surface at a distal end.

12. A mechanism for positioning a work piece, the mechanism comprising:

a support member comprising;

a main body, and

a mounting portion coupled to the main body, the mounting portion axially defining a mounting hole; and

a position assembly comprising;

a guiding member detachably coupled to the mounting hole of the mounting portion, and

a positioning sleeve sleeved on the guiding member and detachably coupled to the support member;

wherein, the guiding member is partially exposed from the positioning sleeve.

13. The mechanism of claim 12, wherein the mounting portion has an inner thread received in the mounting hole, the guiding member comprises a thread rod detachably threaded with the inner thread of the mounting portion.

14. The mechanism of claim 13, wherein the guiding member further comprises:

a limiting block coupled to the threaded rod, a width of the limiting block larger than a diameter of the thread rod, and

a pin coupled to the limiting block and partially exposed from the positioning sleeve.

15. The mechanism of claim 14, wherein the positioning sleeve axially defines a receiving hole, the receiving hole comprises a first receiving portion, a second receiving portion communication with the first receiving portion, and a third receiving portion communication with the second receiving portion, the mounting portion is received in the first receiving portion, the guiding member is received in the second receiving portion and the third receiving portion, the pin is partially exposed from the third receiving portion.

16. The mechanism of claim 15, wherein a diameter of the third receiving portion is smaller than a diameter of the second receiving portion, a restriction portion is formed between the second receiving portion and the third receiving portion, the restriction portion is configured to restrict an exposing length of the guiding member exposing from the positioning sleeve.

17. The mechanism of claim 16, wherein the limiting block is received in the second receiving portion, a sectional size of the second receiving portion matches a sectional size of the limiting block, a height of the second receiving portion is larger than a height of the limiting block, the limiting block is configured to slide along the second receiving portion.

18. The mechanism of claim 12, wherein the mounting portion radially defines an inserting hole, the positioning sleeve radially defines a through hole corresponding to the inserting hole, a fastener is detachably inserted into the through hole and the inserting hole.

19. The mechanism of claim 12, wherein the mounting portion radially defines two inserting holes, the positioning sleeve radially defines a through hole, a fastener is detachably inserted into one of the inserting holes and the through hole.

20. The mechanism of claim 12, wherein the positioning sleeve has a conical surface at a distal end.
