Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of thickness measurement, in particular to a grinding wheel detection device. Background Art
[0002] Grinding wheel is the most widely used abrasive tool. It rotates at high speed when used and can perform rough grinding, semi-finishing grinding and fine grinding, as well as grooving and cutting on the outer circle, inner circle, plane and various profiles of metal or non-metal workpieces. Grinding wheel is a fixed abrasive tool with a certain strength that is fixed by a binder to a certain shape of abrasive. It is generally composed of abrasive, binder and pores. With the development of mechanical processing industry, high-thickness grinding wheel is increasingly widely used, but the higher the thickness of the grinding wheel, the greater the difficulty and cost of production. The existing high-thickness grinding wheel adopts an integrated molding mechanism. After pressing and sintering, due to its large thickness, the inside and surface of the grinding wheel are heated unevenly. If the internal binder of the grinding wheel needs to be melted, a longer temperature and sintering time are required. However, the longer sintering temperature and sintering time will cause cracks to easily appear on the surface of the grinding wheel, resulting in scrapped products. At the same time, after the high-thickness grinding wheel is produced, its thickness needs to be measured to determine whether the product meets the requirements.
[0003] The thickness of the grinding wheel is mainly detected manually. Workers use measuring tools to manually measure the thickness of the grinding wheel to see if the thickness of the grinding wheel meets the specified size. This measurement method mainly relies on manual labor, which greatly increases the labor intensity of workers, is time-consuming and labor-intensive, and inefficient. At the same time, workers will become fatigued after long-term detection, which is likely to cause detection errors, resulting in large errors in the detection of grinding wheel thickness.

[0021] (III) Beneficial effects
[0022] Compared with the prior art, the utility model provides a grinding wheel detection device, which has the following beneficial effects:
[0023] (1) The grinding wheel detection device starts the motor when the thickness of the grinding wheel needs to be detected. The motor starts to transmit power from the output end, drives the rear transmission shaft to rotate, the rear transmission shaft drives the rear threaded rod to rotate, the rear threaded rod drives the rear rotating shaft to rotate, the rear rotating shaft drives the rear sprocket to rotate, the rear sprocket drives the front sprocket to rotate through the chain, the front sprocket drives the front rotating shaft to rotate, the front rotating shaft drives the front threaded rod to rotate, and when the two threaded rods rotate, they drive the threaded lifting block to move up and down, the lifting block drives the first fixed block to move, and then the lifting block is adjusted to a suitable height through the scale line, and then the grinding wheel passes between the lifting block and the second fixed block.

[0024] (2) The grinding wheel detection equipment can make the grinding wheel move to the detection position more easily and quickly through the inclined surfaces of the first fixed block and the second fixed block. A normal grinding wheel can pass through after contacting the lower side of the lifting block and the upper side of the second fixed block. Because the lower side of the lifting block is a frosted surface, the worker needs to use some thrust when the grinding wheel passes through. If the grinding wheel cannot enter between the lifting block and the second fixed block, it means that the thickness of the grinding wheel is too thick. If the grinding wheel passes between the lifting block and the second fixed block easily, it means that the upper side of the grinding wheel does not contact the frosted surface of the lower side of the lifting block, which further indicates that the thickness of the grinding wheel is too thin. There is no need to spend time to align the grinding wheel with the lifting block and the second fixed block, so that it is easier and faster to insert the grinding wheel between the lifting block and the second fixed block. At the same time, the frosted surface on the lower side of the lifting block can easily and quickly determine whether the grinding wheel is too thin, making the thickness detection of the grinding wheel more time-saving and labor-saving.
