Rocker arm type auxiliary clamping device for numerical control machining

Abstract

The invention provides a rocker arm type auxiliary clamping device for numerical control machining. The device comprises a fixing structure. The upper end face of the fixing structure is slidably provided with a sliding structure. An adjusting structure is integrally vertically and slidably fixed to the sliding structure. The adjusting structure is connected with the root of a rocker arm structure, and the tail end of the rocker arm structure is sleeved with a clamping structure. An adjusting rotary knob is installed on the adjusting structure through threads, and the position distance of theadjusting rotary knob can be adjusted through the threads, an adjusting block installed at the tail end of the adjusting rotary knob is in a rotatable state integrally, the adjusting block cannot rotate along with adjustment and rotation of the adjusting rotary knob, and meanwhile the tail end of the adjusting block is slidably installed inside an inclined sliding groove. When the adjusting blockmoves along with rotation of the adjusting rotary knob, the adjusting block can be driven to move backwards, and therefore the adjusting block can lift the whole rocker arm along the trajectory of theinclined sliding groove, and the purpose of adjusting and opening a rocking lever is achieved.

Description

technical field [0001] The invention belongs to the technical field of numerical control machining, and more specifically relates to a rocker-type auxiliary clamping device for numerical control machining. Background technique [0002] CNC machining refers to a process method for processing parts on CNC machine tools. The process regulations of CNC machine tool processing and traditional machine tool processing are generally consistent, but significant changes have also taken place. A machining method that uses digital information to control the movement of parts and tools. It is an effective way to solve the problems of variable varieties, small batches, complex shapes, and high precision, and to realize high-efficiency and automatic processing. However, there are many kinds of processing fixtures on general CNC machine tools, chuck-shaped, and thread-fixed. , rocker-shaped, etc. [0003] Application number: In the patent of CN201611224936.8, the present invention disclos...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention provides a rocker-arm auxiliary clamping device for numerical control machining to solve the problem that the existing rocker-arm clamp has a single function and cannot perform stable tightening on multiple positions of the workpiece. It is easy to shake in the middle, and the clamping force of the workpiece cannot be adjusted.
