Description

Technical Field

[0001] The present invention relates to the technical field of grinding processing, and particularly relates to a grinding device for processing non-standard parts. Background Art

[0002] With the gradual expansion of the application fields of diaphragm compressors, the types of compressed gases are increasing. The working principle of a diaphragm compressor is as follows: First, the gas is introduced into the air chamber through the intake holes on the cylinder head, then the piston drives the hydraulic oil to flow, and the hydraulic oil then pushes the diaphragm to deform and move upward, so that the volume of the air chamber decreases. Finally, the gas is exported from the air chamber through the outlet holes on the cylinder head and enters the gas storage tank.

[0003] Currently, neither the intake holes nor the outlet holes on the cylinder head are a single hole, but are composed of a group of evenly distributed small holes. This is to avoid obvious indentations on the diaphragm when the diaphragm fits to the intake holes and outlet holes, which would seriously reduce the expected service life of the diaphragm. After the drilling process of this group of intake holes and outlet holes, it is also necessary to grind and remove the drilling burrs at the orifice. This process is completed one by one by manually holding an electric grinding pen, which is quite time-consuming and laborious. During the grinding process, some cold water is selectively sprayed at the grinding position for cooling, and finally the grinding results of each hole are not uniform. Summary of the Invention

[0007] The grinding mechanism is arranged at an upper position and is used for simultaneously grinding all the intake holes and outlet holes on the cylinder head in the same batch.

[0010] Preferably, a triangular prism-shaped drainage groove 1 is evenly provided on the side surface of the middle fixed block; and a triangular prism-shaped drainage groove 2 is evenly provided on the side surface of the offset fixed block.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. Self-centering clamping. The piston rod of the hydraulic cylinder contracts and drives a circle of side clamps to move downward and inward, and the side clamp grooves on the side clamps are pressed against the edge of the cylinder cover.

[0014] 2. Grinding in the same batch.

[0015] 3. Cooling, lubricating and cleaning with coolant. When the piston rod of the cylinder II contracts, a negative pressure environment will be formed above the moving plate, and then the coolant in the clamping space of the anti-rotation tube will be sucked into the internal space of the anti-rotation tube through the suction holes. When the piston rod of the cylinder II extends, the upward moving plate will squeeze the coolant in the internal space of the anti-rotation tube into the clamping space of the anti-rotation tube through the suction holes, thereby increasing the pressure of the coolant in the clamping space. The coolant in the clamping space is vertically ejected through the outflow holes to clean the ground cylinder head, and the coolant in the clamping space is horizontally ejected through the ejection holes to cool, lubricate and clean all the grinding rods.
