A bushing automatic shrinking machine

Abstract

The invention discloses an automatic size reducing machine for a bushing. The machine comprises a rack, a rotating disc feed device, an oil pressure system, a size reducing mechanism, a detection system, a product transfer mechanism, an operating box, a fork ascending assembly, a discharging device and an air channel assembly, wherein the size reducing mechanism is arranged on the front side of the middle of the rack; the rotating disc feed device is arranged on one side of the size reducing mechanism, and the detection system is arranged on the other side of the size reducing mechanism; the product transfer mechanism is arranged above the rotating disc feed device; the fork ascending assembly is connected below the product transfer mechanism; the oil pressure system is arranged on the rear side of the size reducing mechanism; the air channel assembly is arranged on the rear side of the detection system; the discharging device is arranged above the air channel assembly; the rotating disc feed device transfers a bushing to be subjected to size reducing to the lower part of the fork ascending assembly, the bushing is transferred to the size reducing mechanism for performing size reducing and taken out to be detected by the detection system; and finally, the discharging device classifies and discharges the detected bushings. Therefore, automatic size reducing of the bushing can be realized, whether the processed bushing is sleeved, the inner hole, height and outer diameter of the bushing can be detected at a time, and the application effect is excellent.

Description

technical field [0001] The invention relates to the field of bushing production equipment, in particular to an automatic bushing reducing machine. Background technique [0002] Bushing, a ring that acts as a pad. In the field of valve application, the bushing is inside the valve cover, and corrosion-resistant materials such as polytetrafluoroethylene or graphite are generally used for sealing. [0003] In the moving parts, the wear of the parts is caused by long-term friction. When the gap between the shaft and the hole is worn to a certain extent, the parts must be replaced. Therefore, the designer chooses the one with lower hardness and better wear resistance when designing. The material is a shaft sleeve or a bushing, which can reduce the wear of the shaft and seat. When the bushing or bushing is worn to a certain extent, it can be replaced, which can save the cost of replacing the shaft or seat. Generally speaking, the bushing and seat are made of Interference fit, and...

AI Technical Summary

Problems solved by technology

The radial tightness of the bushing is an important factor to determine its installation and use effect, and it is also a time-consuming processing link. Therefore, the diameter reduction processing of the bushing is particularly important, especially the diameter reduction processing of the bushing. It can be used only if the inner hole inspection, height inspection and outer diameter inspection are all qualified. There is no good processing equipment in the industry so far.
