Embodiment 2

[0026] In addition to all the technical features of the first embodiment, this embodiment also includes:

[0027] A first limiting ring 401 and a second limiting ring 403 are fixedly mounted on one side of the two groups of clamping blocks 404, respectively. The anti-slip pad 6 arranged in conjunction with the first limiting ring 401 and the second limiting ring 403 helps to increase friction and enhance the firmness of the milling cutter installation.

[0028] A guide groove 406 is formed on the surface of the mounting seat 405, and the guide groove 406 can play a guiding role.

[0029] The inner walls of the first limiting ring 401 and the second limiting ring 403 are both bonded with anti-skid pads 6.

[0030] In addition to all the technical features of the first embodiment, this embodiment also includes:

[0031] The auxiliary positioning component 5 includes positioning holes 501 , which are opened on the outer surface of the thread milling cutter body 2 . There are three groups of positioning holes 501 . By adjusting the positions of the positioning rods 502 in different positioning holes 501 , the installation depth of the thread milling cutter body 2 is adjusted.

[0032] A positioning rod 502 is fixedly installed on one side of the inner part of the first limiting ring 401 and the second limiting ring 403 . The positioning rod 502 passes through the positioning hole 501 to assist in positioning.

[0034] Working principle: When using the thread milling cutter clamping fixture with an auxiliary positioning structure, the thread milling cutter body 2 can be placed in the center position of the mounting seat 405 through the set limit assembly 4, and then the rotating adjustment block 402 drives the second rotating shaft 413 to rotate, and then drives the first bevel gear 407 to rotate, so that the second bevel gear 408 rotates, drives the first rotating shaft 409 and the first connecting block 410 to rotate at an angle, and the first connecting block 410 drives the slider 412 to slide along the inside of the guide groove 406 through the second connecting block 411, so that the clamping block 404 on one side of the slider 412 drives the first limit ring 401 and the second limit ring 403 to extend and retract synchronously, completing the alignment. The limiting fixation of the thread milling cutter body 2, in conjunction with the anti-slip pad 6, can improve the friction and enhance the installation firmness of the milling cutter, while buffering the forces exerted on the first limiting ring 401, the second limiting ring 403 and the mounting seat 405, thereby protecting the mounting seat 405. This arrangement solves the problem that some existing thread milling cutter clamping tools have general fixing firmness when installing the milling cutter, and are more troublesome to install, which brings inconvenience to the processing and reduces the processing efficiency. The arrangement is very practical. By setting the auxiliary positioning component 5, the position of the positioning rod 502 in different positioning holes 501 is adjusted, that is, the installation depth of the thread milling cutter body 2 is adjusted, thereby improving the applicability of the device.
