A U-shaped notch processing system for impact samples

Abstract

The invention discloses an impact sample U-shaped notch machining system. The impact sample U-shaped notch machining system comprises a grinding wheel, a plane grinding machine and a grinding machinecontrol module for controlling the plane grinding machine to move horizontally, wherein the grinding wheel is located above the plane grinding machine, and the impact sample U-shaped notch machining system further comprises a grinding wheel dressing device, the grinding wheel dressing device comprises a dressing controller, a diamond pen which the pen point can be in contact with the outer edge ofthe grinding wheel, the diamond pen is fixedly connected with the rotating seat which can drive, the diamond pen to trim the outer edge of the grinding wheel through the pen holder, the rotating platform is arranged on the moving platform which can drive the rotating platform to horizontally move relative to the outer edge of the grinding wheel; the dressing controller is in transmission connection with the rotary seat through a rotary driver, and the dressing controller is in transmission connection with the mobile platform through a translation driver. The device is simple to operate, convenient and rapid, high in notch machining precision, high in efficiency, safe, reliable and low in cost.

Description

technical field [0001] The invention belongs to the technical field of industrial automatic processing, in particular to a U-shaped notch processing system for impact samples. Background technique [0002] In the prior art, the processing of the U-shaped notch of the impact specimen generally includes the following steps: (1) thinning the grinding wheel with an initial thickness greater than 2 mm to a thickness of 2 mm on a lathe; (2) installing the grinding wheel with a thickness of 2 mm on the grinding machine; ( 3) Manually trim the outer edge of the grinding wheel into a hemispherical surface; (4) Grind the sample with a grinding wheel; (5) Use a projector to observe the shape and size of the arc surface of the sample; (6) Manually trim the grinding wheel again according to the observation results; (7) Process the notch to the upper limit of tolerance; (8) Process and grind the notch mold; (9) Grind the sample on the abrasive tool coated with abrasive paste to the requir...

AI Technical Summary

Problems solved by technology

[0003] It can be seen that the whole process of processing the U-shaped notch of the impact sample using the existing method is very cumbersome, the number of times to disassemble the grinding wheel and transfer the sample is high, the processing efficiency is low, and many auxiliary equipment are used. A lathe, a grinder, and a projector are required to observe the grinding wheel. Dressing effect requires many operators, manually dressing the grinding wheel is time-consuming and laborious, and the efficiency is very low. When working on the outer edge of the grinding wheel, the operator needs to face the high-speed running grinding wheel at close range. The risk of damage to the human body due to the grinding wheel breaking is high, and the safety factor is low; moreover, it is necessary to process the abrasive tool and perform a special grinding process. It also needs to be trimmed later, and manual grinding is time-consuming and laborious
