Grinder for part machining

Abstract

The invention belongs to the technical field of machine tools or devices suitable for grinding part planes, and particularly discloses a grinder for part machining. The grinder comprises a rack, a transmission unit, a motor and two grinding units; the grinding units comprise telescopic rods and grinding discs, and first gears are arranged on the telescopic rods; the transmission unit comprises a rotating shaft and a piston cylinder; a plunger is slidably connected into the piston cylinder; a closed curved groove is formed in the inner wall of the rotating shaft, and a push rod is arranged on the plunger; a water inlet pipe and a water drainage pipe are connected to the piston cylinder, a one-way water inlet valve is arranged on the water inlet pipe, and a one-way water drainage valve is arranged on the water drainage pipe; a second gear and a fixing ring are arranged on the rotating shaft; and a plurality of clamping mechanisms are arranged on the fixing ring and located between the two grinding units, and comprise cross rods fixed to the fixing ring and clamps arranged on the cross rods and used for clamping parts. By using the grinder for part machining, the two opposite side faces of the parts can be ground simultaneously, the multiple parts can be ground simultaneously, and the efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of machine tools or devices suitable for grinding parts planes, and in particular relates to a grinding machine for parts processing. Background technique [0002] A grinder is a machine tool that uses abrasive tools to grind the surface of parts. Most grinding machines use high-speed rotating grinding wheels for grinding, and a few use other abrasive tools such as oil stones and abrasive belts and free abrasives for processing, such as honing machines, superfinishing machine tools, abrasive belt grinders, grinding machines and polishing machine etc. The grinding machine can process materials with higher hardness, such as hardened steel, hard alloy, etc.; it can also process brittle materials, such as glass and granite. The grinding machine can be used for grinding with high precision and small surface roughness, as well as high-efficiency grinding, such as powerful grinding. [0003] In the existing grin...

AI Technical Summary

Problems solved by technology

[0003] In the existing grinding machine tools, if two symmetrical planes are to be grinded on the part, the method of clamping or adsorption is generally adopted, and one plane is processed first, and then the other plane is processed, or a single part is corrected and clamped, Then it is sent into the gap between the two ends of the double grinding wheel for grinding, which is troublesome to operate, and only one part can be ground at a time, so the efficiency is low
