[0002] Polishing refers to a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of a workpiece to obtain a bright and smooth surface. Polishing is a modification of the workpiece surface using polishing tools and abrasive particles or other polishing media, and cast iron wheels need to be polished during the production process.

[0003] In order to enable the polishing device to polish cast iron wheels of various sizes, the polishing blocks inside the polishing device generally need to be replaced frequently. Therefore, the polishing blocks installed inside most polishing devices are detachable. There will inevitably be a gap between the polishing block and the inside of the polishing device. During the polishing process, the polishing block is in close contact with the cast iron wheel. When the cast iron wheel is driven to rotate for polishing, the polishing block will be shifted, which will cause uneven contact force between one end of the polishing surface of the polishing block and the cast iron wheel, thereby affecting the polishing effect and efficiency.

[0017] A polishing method of a polishing device for processing a cast iron wheel, comprising the following steps:

[0018] S1: Install the cast iron wheel to be polished on the limit mounting frame, and fix the cast iron wheel by installing nuts on the two plug rods on the limit mounting frame;

[0019] S2: The motor then drives the double-gear transmission shaft to rotate, and the cast iron wheel connected to the limit feed rack is sent to the inside of the main body;

[0020] S3: After the cast iron wheel on the limit feed rack is transferred to the inside of the main body, the connection between the limit feed rack and the sliding tooth plate will abut against the outer wall of the main body entrance, and the position of the limit feed rack is limited so that the cast iron wheel corresponds to the detachable polishing block;

[0021] S4: The polishing device is then controlled to descend by the hydraulic cylinder, so that the detachable polishing block is engaged with the outer wall of the cast iron wheel, and the cast iron wheel on the limit mounting frame is driven to rotate by the polishing motor to polish the cast iron wheel.

[0022] The present invention has the following beneficial effects:

[0023] (1) When the electric push rod of the present invention controls the polishing device to descend, the lower pressure frame will be against the top of the main body. As the polishing device drives the two extension plates to continue to descend, the extension plates will slide on the outer wall of the lower pressure frame through the lifting slot frame, so that the lower pressure frame and the push strip will gradually become vertical, pushing the sliding frame to move inside the strip-shaped sliding hole toward one end close to the polishing device, and at the same time squeezing the compression spring, thereby driving the connecting block to move toward one end of the detachable polishing block, so that the two clamping limit frames are respectively against the two sides of the detachable polishing block. The clamping limit frames will be compressed and shrink and slide inside the shrinkage groove, pushing the reset spring for squeezing, so that the detachable polishing block can be clamped, thereby improving the stability of the connection between the detachable polishing block and the inside of the installation groove, reducing the amplitude of the position deviation of the detachable polishing block caused by the rotation of the cast iron wheel, and then reducing the occurrence of uneven contact force between the detachable polishing block and the cast iron wheel, thereby improving the polishing effect and efficiency.

[0024] (2) The present invention installs the cast iron wheel to be polished on the limit mounting frame, fixes the cast iron wheel by installing nuts on the two plug rods on the limit mounting frame, and then drives the double-gear transmission shaft to rotate through the motor to send the cast iron wheel connected to the limit feeding frame to the inside of the main body. When the closing plate is too low at the inlet of the main body, the cast iron wheel on the limit feeding frame will contact the sliding belt frame. Through the inclined posture of the sliding belt frame, the cast iron wheel can directly contact the sliding belt on the sliding belt frame during the transmission of the cast iron wheel to the inside of the main body, and the closing plate with a height that is too low can be pushed upward. When the entrance of the main body is not fully opened due to the mistake of the staff, resulting in the closing plate opening the inlet of the main body at a low height, the cast iron wheel can be prevented from colliding with the machine when being transmitted to the inside of the main body, thereby avoiding damage to the device on one side. In addition, through the sliding arrangement on the sliding belt frame, the friction between the cast iron wheel and the sliding belt frame can be reduced, the wear on the cast iron wheel can be reduced, and the practicability of the device is improved.

[0025] (3) After the present invention transfers the cast iron wheel on the limit feed rack to the inside of the main body, the connection between the limit feed rack and the sliding tooth plate will abut against the outer wall of the main body entrance, limiting the position of the limit feed rack so that the cast iron wheel corresponds to the detachable polishing block, and then controlling the polishing device to descend by the electric push rod so that the detachable polishing block is engaged with the outer wall of the cast iron wheel. The cast iron wheel on the limit mounting rack is driven to rotate by the polishing motor to polish the cast iron wheel. The debris generated during polishing will fall into the gap between the top of the limit feed rack and the bottom of the main body and the limit feed rack. When the limit feed rack is transmitted outward and drives the two moving racks to slide inside the feed moving hole, it will simultaneously drive the moving rack to slide at the bottom of the main body, so that the debris on the top of the limit feed rack can be removed. When the vibration generated by the movement of the limit feed rack drops to the inner wall of the bottom of the main body, the mobile rack is used to scrape and clean the debris on the inner wall of the bottom of the main body, and the debris is pushed to the end close to the outlet, so that the debris falls into the chip box at the bottom of the main body. In the process of the mobile rack scraping the debris from the inner wall of the bottom of the main body, if there are a lot of debris, the accumulated debris will enter the dispersion groove. The bottom of the dispersion groove has two opposite inclined surfaces, which will disperse the debris entering the dispersion groove into the two through holes and fall into the chip box below, so as to avoid the situation where the debris scraped by the mobile rack during movement exceeds the height of the mobile rack to the back of the mobile rack due to the large amount of debris on the inner wall of the bottom of the main body, thereby avoiding affecting the scraping effect of the mobile rack on the inner wall of the bottom of the main body.

[0026] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

The debris generated during polishing will fall into the gap between the top of the limit feed rack 204 and the bottom of the main body 1 and the limit feed rack 204. When the limit feed rack 204 is transmitted outward and drives the two moving racks 201 to slide inside the feed moving hole 101, it will synchronously drive the moving rack 201 in the main body 1.

During the internal transmission of the main body 1, the cast iron wheel is directly in contact with the sliding belt on the sliding belt frame 405, and the closing plate 404 with a height that is too low is pushed upward. When the entrance of the main body 1 is not fully opened due to the mistake of the staff, resulting in the closing plate 404 opening the feeding port of the main body 1 at a low height, the cast iron wheel is prevented from colliding with the machine when being transmitted to the inside of the main body 1, thereby avoiding damage to the device on one side, and the sliding provided on the sliding belt frame 405 can reduce the friction between the cast iron wheel and the sliding belt frame 405.

[0048] After the cast iron wheel on the limit feed rack 204 is transmitted to the inside of the main body 1, the connection between the limit feed rack 204 and the sliding tooth plate 203 will be against the outer wall of the entrance of the main body 1, and the position of the limit feed rack 204 will be limited so that the cast iron wheel corresponds to the detachable polishing block 305, and then the polishing device 303 is controlled to descend by the electric push rod 301, so that the detachable polishing block 305 is embedded with the outer wall of the cast iron wheel, and the cast iron wheel on the limit mounting frame 206 is driven to rotate by the polishing motor 205 to polish the cast iron wheel. The debris generated during polishing will fall into the gap between the top of the limit feed rack 204 and the bottom of the main body 1 and the limit feed rack 204. When the limit feed rack 204 is transmitted outward and drives the two moving racks 201 to slide inside the feed moving hole 101, it will synchronously drive the moving rack 201 to slide at the bottom of the main body 1, so that the debris at the top of the limit feed rack 204 can be When the chips fall to the inner wall of the bottom of the main body 1 due to the vibration generated by the movement of the limited feeding rack 204, the mobile rack 201 scrapes and cleans the chips on the inner wall of the bottom of the main body 1, and pushes the chips to the end close to the outlet, so that the chips fall into the chip box 103 at the bottom of the main body 1. In the process of the mobile rack 201 scraping the chips on the inner wall of the bottom of the main body 1, if there are a lot of chips, the accumulated chips will enter the dispersion groove 208. The bottom of the dispersion groove 208 has two opposite inclined surfaces, so the chips entering the dispersion groove 208 will be dispersed into the two through holes 209 and fall into the chip box 103 below, so as to avoid the chips scraped by the mobile rack 201 during movement due to the large amount of chips on the inner wall of the bottom of the main body 1 exceeding the height of the mobile rack 201 to the rear of the mobile rack 201, thereby avoiding affecting the scraping effect of the mobile rack 201 on the inner wall of the bottom of the main body 1.
