In the description of the present utility model, the meaning of "plurality" is more than two, unless otherwise clearly and specifically limited.

[0025] like Figure 1-Figure 5 As shown, the utility model provides a thread block fixture with high stability, which is used to clamp a thread block 10, and the thread block 10 has a mounting hole 11 and a plurality of insertion holes 12. The fixture includes a base 20, a support platform 30, a positioning column 40 and a pressing plate 50.

[0026] The base 20 is fixedly mounted on the workbench.

[0027] The support platform 30 is fixedly mounted on the top of the base 20 .

[0028] The positioning column 40 is fixedly mounted on the top of the support platform 30 along the longitudinal direction. A threaded hole 41 extending downward is formed on the top of the positioning column 40 . The positioning column 40 is adapted to the mounting hole 11 .

[0029] The pressing plate 50 is disposed above the support platform 30 in the transverse direction, and a through hole 51 is formed on the pressing plate 50 and penetrates in the longitudinal direction. A screw 52 is disposed on the pressing plate 50, and the threaded end of the screw 52 passes through the through hole 51 and matches with the threaded hole 41.

[0030] The specific use process of the clamp is as follows: first, the staff places the threaded block 10 on the support platform 30 and matches the mounting hole 11 with the positioning column 40. Then, the staff places the pressing plate 50 on the top of the threaded block 10 and aligns the through hole 51 with the threaded hole 41. Then, the staff passes the threaded end of the screw 52 through the through hole 51 and matches it with the threaded hole 41.

[0031] In this way, the pressing plate 50 will press the thread block 10 onto the support platform 30, and fix the thread block 10 in the vertical direction by clamping the end face of the thread block 10 to prevent the thread block 10 from shaking in the vertical direction; through the cooperation between the positioning column 40 and the mounting hole 11, the thread block 10 is fixed in the horizontal direction to prevent the thread block 10 from shaking in the horizontal direction. On the one hand, the contact surface between the pressing plate 50 and the thread block 10 is larger, and the stability when clamping the thread block 10 will be better; on the other hand, the clamp does not directly contact the threads on the thread block 10, so it will not damage the threads.

[0032] In one embodiment, a plurality of limiting holes 31 are formed on the support platform 30 and extend through the support platform 30 in the longitudinal direction.

[0033] A plurality of inserting rods 53 are fixedly mounted on the bottom of the pressing plate 50 . The plurality of inserting rods 53 are arranged in one-to-one correspondence with the plurality of limiting holes 31 and the plurality of inserting holes 12 . The inserting rods 53 are adapted to the limiting holes 31 and the inserting holes 12 .

[0034] After the staff matches the mounting hole 11 with the positioning column 40, they align the multiple sockets 12 with the multiple limit holes 31 respectively, and then insert the multiple insertion rods 53 on the pressure plate 50 through the corresponding sockets 12 and into the corresponding limit holes 31 respectively, and finally pass the threaded end of the screw 52 through the through hole 51 and match it with the threaded hole 41.

[0035] In this way, due to the cooperation between the insertion rod 53, the insertion hole 12 and the limiting hole 31, the threaded block 10 will not rotate, the fixing effect of the threaded block 10 is better, and the stability is further improved.

[0036] In one embodiment, a rubber ring 54 is sleeved on the threaded end of the screw 52, ​​and the rubber ring 54 is located between the head of the screw 52 and the pressing plate 50. The rubber ring 54 can prevent the head of the screw 52 from directly contacting the end face of the threaded end, thereby protecting the end face of the threaded end from damage.

[0037] In one embodiment, the number of the jacks 12 is three.

[0038] In one embodiment, the three insertion holes 12 are arranged at equal intervals along the circumference of the positioning column 40 .

[0039] In one embodiment, the diameter of the through hole 51 is larger than the diameter of the threaded end of the screw 52, ​​so that the staff can flexibly adjust the position of the screw 52 for easy operation.

[0040] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model.
