It can be understood that the above-mentioned scheme can be used in the scene of parts grinding, and can also be used to solve the problem that a lot of dust adheres to the inner wall of the component, which is inconvenient to clean.
[0024] According to the present specific embodiment, the pressure regulating cylinder 101 is provided with an adjusting rod 103, a push plate 104, a damping rod 105, a pressure spring 106, a slider 107 and an electric push rod 108 in sequence from top to bottom. A pressure sensor 109 is provided at the output end of the electric push rod 108, a stabilizing seat 110 is provided below the pressure sensor 109, a dust cover 111 is provided outside the stabilizing seat 110, an electric grinder 112 is provided below the stabilizing seat 110, and a rotating shaft 113 is provided at the output end of the electric grinder 112. A grinding sheet 114 is provided at one end of the rotating shaft 113, a vacuum cleaner 115 is provided on the workbench 102, and the vacuum cleaner 115 is connected to the dust cover 111 through a delivery pipe. The pressure regulating cylinder 101 is fixedly connected to the workbench 102 and is located in the middle of the workbench 102. The grinding pressure of the electric grinder 112 below is monitored by the pressure sensor 109. When the pressure increases, the electric push rod 108 contracts to make the electric grinder 112 rise, reduce the grinding pressure, and prevent excessive grinding of parts. Grinding to ensure the qualified rate of finished products. When the pressure is too low, the electric push rod 108 is stretched to increase the pressure between the grinding sheet 114 at the lower end of the electric grinder 112 and the surface of the parts to ensure the grinding efficiency. The damping rod 105 and the pressure spring 106 can not only support the electric grinder 112, but also have an overpressure buffering effect to prevent the wrong operation or equipment failure from causing the pressure between the grinding sheet 114 and the surface of the parts to increase suddenly, resulting in over-grinding of the surface of the parts and damage to the electric grinder 112 and the grinding sheet 114 at the lower end. By rotating the adjusting rod 103, the push plate 104 pushes the damping rod 105 and the pressure spring 106 to contract and stretch, and the supporting force of the damping rod 105 and the pressure spring 106 on the electric grinder 112 below can be adjusted to ensure the grinding effect. The dust hood 111 can prevent dust from flying during grinding. The dust hood 111 is connected to the dust collector 115 through a conveying pipe. The dust collector 115 sucks away the dust particles inside the dust hood 111 to prevent the dust particles from falling on the surface of the parts and affecting the grinding accuracy.
[0025] The two sides of the triangular scraper 116 have inclined surfaces 118, the inner wall of the collection tray 117 has a thread groove 119, the middle of the collection tray 117 has a through hole 120, the outer side of the dust cover 111 has a thread, and the plurality of triangular scrapers 116 are respectively fixedly connected to the support frame and are located on the support frame.

The multiple triangular scrapers 116 are respectively fixedly connected to the corresponding support rods 122 and are located at one end of the support rods 122. The circular ring 123 is fixedly connected to the rotating shaft 113 and is sleeved on the rotating shaft 113. Through the connection between the support rods 122 and the circular ring 123, the triangular scrapers 116 can be driven by the rotating shaft 113 to scrape off the dust on the inner wall of the dust hood 111.
[0028] When the utility model is used to clean the dust on the inner wall of the dust hood 111, the electric grinder 112 is started to rotate the shaft 113, and the ring 123 is driven to rotate, and the ring 123 drives the plurality of support rods 122 to rotate, so that the plurality of triangular scrapers 116 are in contact with the inner wall of the dust hood 111, so that the dust on the inner wall of the dust hood 111 is scraped off, and the scraped dust falls into the collection tray 117 for collection, so that when the dust in the collection tray 117 is full, By rotating the collecting tray 117, the collecting tray 117 can be removed from the dust hood 111, and the dust in the collecting tray 117 can be cleaned. In this way, the problem that a lot of dust will adhere to the inner wall of the dust hood 111 after long-term use is solved. Since the space between the electric grinder 112 and the dust hood 111 is relatively narrow, it is not convenient to clean the dust. During cleaning, the dust is easy to fall onto the workbench 102, and the workbench 102 needs to be cleaned.
