Automobile engine valve locking plate grinding equipment

Abstract

Automobile engine valve locking plate grinding equipment comprises a lathe bed, a horizontal moving mechanism, a vertical moving mechanism and a grinding mechanism. The horizontal moving mechanism, the vertical moving mechanism and the grinding mechanism are arranged on the lathe bed, the grinding mechanism comprises an electric spindle and a grinding wheel, a feeding mechanism is arranged above the grinding mechanism, the feeding mechanism clamps a workpiece through a feeding contour wheel and conveys the workpiece to the grinding wheel for grinding, and an inclination angle adjusting mechanism is arranged on the feeding mechanism. The feeding contour wheel is matched with a valve locking plate in shape, the workpiece is clamped through the feeding contour wheel and conveyed to a grinding position, and the efficient automatic machining technological process is achieved. A simple and reliable mechanical structure is utilized, the function of adjusting the inclination angle of a feeding center shaft is achieved, and the adaptability of the equipment to the workpiece feeding precision is guaranteed.

Description

technical field [0001] The invention relates to a grinding device, in particular to a grinding device for an automobile engine valve lock plate. Background technique [0002] The valve lock plate is an important part inside the car engine, with small size and irregular shape (such as Figure 9 shown). The outer dimension of the valve lock plate is within 10mm, the outer circle has a taper, and the opposite end face of the outer circle needs to be ground. The roughness is required not to exceed Ra1.6, and the dimensional accuracy is 0.01mm. [0003] The valve lock plate adopts the process route of stamping forming and machining. When grinding the end face, due to the small size, irregular shape and high precision requirements of the parts, the clamping is difficult and the processing efficiency is low. [0004] At present, for the grinding of valve lock plates, general grinding equipment such as surface grinders is generally used to make special fixtures, and one or more wo...

AI Technical Summary

Problems solved by technology

[0006] 1. It is difficult to make fixtures and the efficiency of clamping is low

[0007] 2. During mass grinding, due to the inconsistency in the accuracy of different batches of incoming materials (such as external taper errors, etc.), it is necessary to adjust the clamping accuracy of the fixture at any time, which is time-consuming and labor-intensive, and prone to unqualified products

[0008] 3. Loading, unloading and grinding operations all rely on manual labor, which is difficult to operate and low in processing efficiency
