Gear pitch circle clamping jaw structure

Abstract

The invention provides a gear pitch circle clamping jaw structure. The gear pitch circle clamping jaw structure comprises a main body, moving parts, side parts and a rotating part, wherein the main body is of a cylindrical structure, and a connecting groove is formed in the top end of the main body; a plurality of threaded holes at different positions are formed in the top end of the main body; the moving parts are mounted inside the connecting groove in the top end of the main body, and the main body is of a rectangular structure; the top ends of the side parts are connected with the bottom of the main body in a fixed connection mode, the moving parts are used for receiving power transmitted from the interior of the main body through the bottom, so that the three moving parts are stressedat the same time to move inwards, and then a gear is clamped and fixed; the top ends of the moving parts are of an inclined structure, so that the gear and a turbine can be subjected to downward moving force after being clamped, and then the gear and the turbine are fixed more stably; and a contact part made of a rubber material is used for being in direct contact with the gear and the turbine, so that the contact part made of the rubber material can achieve an anti-skid effect.

Description

technical field [0001] The invention belongs to the technical field of jaws, and more specifically relates to a gear pitch circle jaw structure. Background technique [0002] In the mechanical structure, the chuck is used for the chuck, the parts for clamping the workpiece, or the machine tool accessories for clamping and positioning the workpiece. Most of them are evenly distributed in 360 degrees, so that the three claws approach or withdraw from the center at the same time to complete the work. [0003] For example, the application number: CN201720193036.5 relates to a gear claw, including a base, a threaded rod is provided on the base, a top block is fixedly installed on the top of the threaded rod, and a receiving plate is movably connected to the threaded rod below the top block. There are several symmetrical claws hinged on the receiving plate, the claws are in the shape of an inverted right triangle, and the hypotenuse of the claws is against the top block; the dist...

Problems solved by technology

[0006] In order to solve the above technical problems, the present invention provides a gear pitch circle claw structure to solve the problem of long-term clamping or force clamping when the fixed gear or the turbine needs to be tightened when the existing gear claw structure is in use. Therefore, the gears are prone to slipping or detachment, and the fixing is not stable enough, and when the existing gear claw structure is used, it is easy to slip when it is installed on the placement surface, especially when inserting the chuck key.
