Problems solved by technology

[0002] In machining, it is often necessary to clamp the workpiece. The problem of centering and alignment must also be considered for the clamping and fixing of shaft parts. The current mechanism for clamping shaft parts is relatively complicated and takes up a lot of space. Troublesome, the centering accuracy is not high, which affects the processing quality, and the versatility is poor

Embodiment Construction

[0009] like figure 1 Shown: 1 is the base, and two sliders, namely the left slider 17 and the right slider 10, are installed on the top of the base 1 through the slideway. The left slider 17 and the right slider 10 are slidable on the base 1 . A left nut 18 is fixedly installed in the left slider 17 , and an adjustment pad 19 is provided between the end of the left nut 18 and the left slider 17 . A right nut 11 is fixedly installed in the right sliding block 10 , and an adjustment pad is also provided between the end of the right nut 11 and the right sliding block 10 . Both the left screw nut 18 and the right screw nut 11 are matched with the same screw 9 but the rotation directions of the threads are opposite. One end of the lead screw 9 is connected with the output shaft of the motor 7 through the coupling 6 , and the motor 7 is fixedly connected with the base 1 through the connecting seat 8 . A left chuck 16 is connected to the left slider 17 , and a right chuck 12 is co...

Abstract

The invention discloses a synchronous centering and clamping mechanism which comprises a base. Two sliding blocks are arranged on the base through sliding rails, a nut is fixedly arranged in each sliding block, the two nuts are both matched with the same lead screw, the rotating directions of the threads of the two nuts are opposite, one end of the lead screw is connected with the output shaft of a motor, a chuck is connected to each sliding block, and clamping blocks for clamping workpieces are arranged on the opposite inner sides of the two chucks. The synchronous centering and clamping mechanism is simple in overall structure, small in occupied space, accurate in centering and alignment, convenient to mount and maintain and capable of improving machining quality.

Description

technical field [0001] The present invention relates to a clamping mechanism, in particular to a synchronous centering clamping mechanism for machining. Background technique [0002] In machining, it is often necessary to clamp the workpiece, and the clamping and fixing of shaft parts must also consider the problem of alignment. The current mechanism for clamping shaft parts is relatively complex, takes up a lot of space, and the clamping is centered. It is troublesome, the centering accuracy is not high, the processing quality is affected, and the versatility is poor. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a synchronous centering and clamping mechanism with simple structure, small occupied space, accurate centering, improved processing quality and wide applicability, and overcomes the deficiencies of the prior art. [0004] The synchronous centering and clamping mechanism of the present invention includes a base, on which two...
