Constant pressure output air cylinder for grinding feed mechanism

Abstract

The invention discloses a constant pressure output air cylinder for a grinding feed mechanism and belongs to the technical field of machine tool equipment. The constant pressure output air cylinder comprises a horizontal valve body, a horizontal pull rod, a bulb handle, a piston, a piston rod, a vertical air cylinder body and a linear motion ball bearing. The horizontal valve body is connected with the vertical air cylinder body and provided with a valve body air input hole, a valve body exhausting hole, a part of a piston upper cavity air channel and a part of a piston lower cavity air channel. The horizontal pull rod is located in the horizontal valve body and provided with a pull rod exhausting hole. The bulb handle is connected with the horizontal pull rod. The piston and the piston rod are located in the vertical air cylinder body. The linear motion ball bearing is located on the inner cavity bottom of the vertical air cylinder body. The bottom end of the piston rod is provided with a grinding stone clamping mechanism installing thread hole. The piston lower cavity air channel is formed above the vertical air cylinder body. The constant pressure output air cylinder outputs pressure stably, is safe and reliable, and effectively ensures machining precision of workpieces.

Description

technical field [0001] The invention relates to a constant output pressure cylinder used for a grinding feeding mechanism, which is used for a grinding stone feeding mechanism of a superfine grinding machine, and belongs to the technical field of machine tool equipment. Background technique [0002] At present, the feeding mechanism of grinding equipment is mostly CNC axis servo feeding, and the grinding process is completed by controlling the feeding amount of the grinding mechanism. Grinding is the last process of finishing, and it is often necessary to stop and measure during the processing , or detect the workpiece on-line, feed the grinding mechanism in a small amount according to the detection results, and complete the final finishing in this way. One of the reasons why the process is so complicated is that the grinding stone is worn out during the machining process, resulting in inconsistent pressure on the workpiece during the grinding process, which affects the accu...

Problems solved by technology

One of the reasons why the process is so complicated is the wear and tear of the grinding stone during the machining process, resulting in inconsistent pressure on the workpiece during the grinding process, which affects the accuracy of the workpiece

At the same time, since the feed of the grinding mechanism is controlled by the displacement of the CNC axis, the loss of the grinding stone has an impact on the contact pressure, which cannot be ground with constant pressure, which affects the dimensional consistency of different workpieces
