Detailed Description

Referring to fig. 1-2, the present invention provides a technical solution:

a clamping device for machining mechanical accessories comprises a fixed seat 1, wherein a limiting groove 101 is formed in the top surface of the fixed seat 1, two movable plates 2 are symmetrically arranged on the top surface of the fixed seat 1, a limiting block 201 is fixedly arranged on the bottom surface of each movable plate 2, a slot 202 is formed in the inner side of each movable plate 2, a clamping piece 3 is screwed in the slot 202, two prisms 4 are symmetrically arranged between the two movable plates 2, the prisms 4 are convenient to limit and penetrate, a spring 401 is sleeved outside each prism 4, the two movable plates 2 are convenient to rapidly separate by the spring 401, a squeezing plate 5 is fixedly arranged between the right ends of the two prisms 4, the squeezing plate 5 is convenient to pull the movable plates 2 on the left side and the movable plates 2 on the right side to move and clamp relatively, a movable groove is formed in the bottom surface of the fixed seat 1, a mounting plate 6 is screwed in the movable groove, a rotating shaft 601 is rotatably connected to the top surface of the mounting plate 6, a worm ring 601 is fixedly provided with a worm wheel 602 on the lower portion of the rotating shaft, and when the worm wheel 602 is convenient to separate from a worm 603, under the action of the return of the spring 401, the two moving plates 2 are driven to return rapidly, a worm 603 is arranged on the outer side of the half-ring worm wheel 602, and a cam 604 is fixedly arranged on the upper portion of the rotating shaft 601.

Specifically, the limiting block 201 is in sliding fit with the limiting groove 101, so that the moving plate 2 is convenient to limit and move.
