Machining fixing and limiting mechanism capable of adjusting limiting strength conveniently

Abstract

The invention discloses a machining fixing and limiting mechanism capable of adjusting limiting strength conveniently. The machining fixing and limiting mechanism comprises a fixed workpiece, clampingmechanisms, adjusting and control mechanisms and a transmission mechanism. The adjusting and control mechanisms are in symmetric threaded rotary sliding connection to the inner end face of the transmission mechanism. If users need to adjust the strength of clamping the fixed workpiece, the users can start fixed motors through the outer adjusting and control mechanisms, the fixed motors can drivegear grooves to shift towards the front portion, then connecting baffles and elastic switches are driven to shift towards the front portion, the shift stroke of limiting clamp blocks is indirectly prolonged at this moment, then shifting generated when the limiting clamp blocks pull spring clamp rings is longer, and the strength that the clamping mechanisms clamp and locate the fixed workpiece is improved; and the users can adjust the distance between the connecting baffles and limiting sliding plates, then the clamping strength to the fixed workpiece is adjusted, the users can adjust the strength of clamping the fixed workpiece rapidly and conveniently, and safety performance of clamping the fixed workpiece is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to a fixed limit mechanism for mechanical processing which is convenient for adjusting the limit force. Background technique [0002] Machining refers to the process in which the user changes the shape, size or performance of the workpiece through mechanical processing equipment, so that the workpiece can meet the standard of use. Now in the machining equipment, it is necessary to process the workpiece To limit the position, so as to facilitate subsequent processing operations, [0003] However, the existing mechanical processing fixing mechanism cannot quickly adjust the strength of the workpiece limit, and when the clamping force is too large, it cannot perform a quick early warning, which reduces the protection force when the workpiece is clamped. [0004] For example, the patent No.: CN201711161188.8 discloses a fixing device for mechanical processing, w...

AI Technical Summary

Problems solved by technology

[0005] Both of the above two patents only adjusted the size and size of the clamped workpiece, but did not adjust the clamping force of the workpiece. The accuracy is greatly reduced, and it is easy to cause insufficient or excessive clamping force, resulting in a reduction in the efficiency of subsequent machining of the workpiece. Therefore, there is an urgent need for a fixed limit mechanism for machining that is easy to adjust the limit force to solve the above existing problems.
