Problems solved by technology

[0002] At present, in the installation process of some transmission mechanisms, it is often encountered that shafts with radial assembly relations are assembled. Since there are no special tools, it is not only difficult to find support points on some smooth shafts, but also encounters problems during gear assembly. Therefore, in the assembly process, not only the assembly operation is cumbersome, the labor intensity is high, and the assembly efficiency is low, but also it is difficult to meet the precision requirements after assembly.

Embodiment Construction

[0014] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0015] Such as figure 1 , figure 2 , image 3 As shown, a handle 12 is fixedly worn on the rear end of the lead screw 1 , and the handle 12 is a small cylindrical structure and is perpendicular to the lead screw 1 . The nut cover support 2 is set on the threaded section of the middle section of the leading screw 1, and the two are threadedly matched and can rotate relatively. A first chuck 7 is arranged at the front end of the lead screw 1, and the first chuck 7 is in the shape of a horizontal "earth", and the end of the front end of the first chuck 7 is a pointed structure. The front end of the screw 1 extends into the first chuck 7 from back to front, and the two are in clearance fit. Two locking square pins 11 are arranged side by side in the middle of the rear transverse section of the first chuck 7. The locking square pins 11 are arranged side by sid...

Abstract

The invention discloses a three-jaw clamp. A threaded rod (1) is sleeved with a nut sleeve support (2), the front end of the threaded rod (1) stretches into a first chuck (7), and balance arms (5) are symmetrically arranged on two sides of the first chuck (7); a clamping arm (6) is arranged between each balance arm (5) and the first chuck (7) and is in an involute shape; limiting pins (8) are symmetrically arranged on two sides of the rear end of the first chuck (7), a return support (9) is arranged between each clamping arm (6) and the first chuck (7), and a return spring (10) is arranged between each return support (9) and the first chuck (7). The three-jaw clamp is simple in structure, and convenient to operate, and saves labor, a part can be accurately clamped and located by rotating the threaded rod, assembly difficulty of the part is lowered, assembly efficiency is improved, and assembly precision of the part is guaranteed effectively.

Description

technical field [0001] The invention belongs to the technical field of component assembly, and in particular relates to a three-jaw caliper. Background technique [0002] At present, in the installation process of some transmission mechanisms, it is often encountered that shafts with radial assembly relations are assembled. Since there are no special tools, it is not only difficult to find support points on some smooth shafts, but also encounters problems during gear assembly. Therefore, in the assembly process, not only the assembly operation is cumbersome, labor-intensive, and assembly efficiency is low, but also it is difficult to meet the precision requirements after assembly. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a three-jaw caliper that can be assembled conveniently and can ensure assembly accuracy. [0004] The technical scheme of the present invention is as follows: a three-jaw caliper, a nut s...
