Clamp used for supporting long and thin tools

Abstract

The invention discloses a clamp used for supporting long and thin tools and relates to the field of precise tool processing equipment. A bushing mounting seat is connected with a bushing mounting seat connection plate through a bushing mounting seat fixing bolt, a bushing is arranged on the bushing mounting seat, a bushing jackscrew is arranged outside the bushing, an air cylinder is connected with the bushing mounting seat connection plate through a cylinder fixing bolt, a parallel two-finger clamp is connected to the right side wall of the air cylinder through a parallel two-finger clamp fixing bolt, shock pads are respectively arranged on the inner wall of an upper jaw and a lower jaw of the parallel two-finger clamp, and two air pipe connectors are arranged at the upper end of the air cylinder. An automatic feeding function in tool processing can be realized, the number of feeding tool bars is reduced, tool processing and producing efficiency are improved by the adoption of modular-based design, and the clamp can be conveniently mounted on a transmitted five-axis tool grinder to be directly used as a function upgraded part.

Description

Technical field: [0001] The invention relates to the field of precision tool processing equipment, in particular to a fixture for supporting slender tools. Background technique: [0002] Cutting tool, as a professional tool for CNC machine tools to process precision parts, its own precision directly determines the precision of the precision parts processed by it. With the rapid development of precision industrial technology, the precision requirements for precision parts are gradually increasing. [0003] Both traditional tool processing and worn tool grinding are carried out on a five-axis linkage precision grinding machine. The movement of these axes is controlled by the numerical control system to process qualified tools or regrind old and old tools into new tools for continued use. ;During processing, the linear axis is continuously fed forward, while the rotary axis is constantly performing high-speed forward and reverse movements according to the shape of the tool to b...

AI Technical Summary

Problems solved by technology

[0005] 1) Since the tool bar is in direct contact with the high-speed rotating grinding wheel at the head during processing, it belongs to contact processing. The effect of high speed and force causes the tool bar to vibrate easily, especially in the processing of slender tools, and may even produce tool damage. The compression deformation of the bar material, once the contact angle between the grinding wheel and the tool bar material and the feed rate deviate, it is easy to cause the tool bar material to break or the tool edge to break out of the gap, resulting in a large number of tool waste products, making the final tool processing The yield rate is not high;

[0006] 2) The tool bar is directly passed through the core of the rotating shaft and clamped on the rotating shaft at its end, leaving a long length at the front end so that multiple tools can be processed with one charge, which will inevitably cause the processing point at the beginning The length of the tool clamped by the chuck is longer, which virtually increases the length of the force arm of the grinding wheel at the processing point, and the tool processed in this state is more susceptible to vibration

[0007] 3) Cannot feed automatically
