Description

Technical Field

[0001] This utility model mainly relates to the field of deburring, specifically to a deburring device with a function of replacing grinding wheels. Background Technology

[0002] Deburring refers to the process of removing burrs or flash from the surface or edges of a part. These burrs or flash are usually formed during the part's machining process, such as drilling, turning, milling, and sheet metal cutting. One of the hazards of burrs is that they can easily cause cuts, so a secondary operation is usually required to remove them.

[0003] When deburring the weld points on the inner wall of the square tube, a deburring device needs to be inserted into the inside of the square tube.

[0004] During the operation of specific embodiments, the inventors discovered the following defects:

[0005] However, because the inner wall of the square tube has right angles, the grinding wheel cannot fit against the right angles of the square tube, which means that the deburring device cannot deburr the inner wall of the square tube evenly, so the right angle positions of the inner wall of the square tube still need to be deburred manually.

[0006] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0030] The deburring structure 2 for the inner wall of a square tube includes an electric push rod 201 and a lifting plate 204. A drive gear 211 is rotatably connected to the bottom of the inner wall of the lifting plate 204, and driven gears 212 are rotatably connected to the center of each of the four sides of the lifting plate 204. The drive gear 211 meshes with the driven gear 212. Adhesive strips 215 are provided at the four corners of the lifting plate 204, and a grinding belt 213 is slidably connected to the outer wall of the four adhesive strips 215. Inner gear teeth 214 are provided at the top and bottom of the inner side of the grinding belt 213, and these inner gear teeth 214 mesh with the driven gear 212. A shaft 205 is provided at the top of the lifting plate 204, and an auxiliary groove 206 is formed inside the shaft 205. The outer wall of the shaft 205 is fitted against the inner wall of the connecting tube 202. The lifting plate 204... An electric telescopic rod 207 is internally provided, and a sliding plate 208 is provided at the output end of the electric telescopic rod 207. The sliding plate 208 is slidably connected to the insertion shaft 205. A connecting rod 209 is rotatably connected between the sliding plate 208 and the insertion shaft 205. A limit strip 210 is provided between the two connecting rods 209. When it is necessary to grind the inner wall of the square tube, different types of grinding belts 213 are used according to the internal size of the square tube. The insertion shaft 205 is inserted into the inner wall of the connecting tube 202. Then the electric telescopic rod 207 is started. The electric telescopic rod 207 pushes the sliding plate 208 to move upward. The sliding plate 208 drives the connecting rod 209 to rotate. The connecting rod 209 drives the limit strip 210 to extend from the inner wall of the auxiliary groove 206 and engage with the slot 203 to fix the lifting plate 204.

[0031] Then, the electric push rod 201 is activated, which drives the lifting plate 204 to rise and fall, allowing the grinding belt 213 to grind the inner wall of the square tube. At the same time, the motor is activated, which drives the drive gear 211 to rotate. The drive gear 211 drives the driven gear 212 to rotate. The driven gear 212 drives the grinding belt 213 to slide on the outer wall of the bonding strip 215 through the inner gear teeth 214. Then, the outer wall of the grinding belt 213 grinds the burrs on the inner wall of the square tube.

[0032] Furthermore, the square tube fixing structure 1 includes a housing 101. A support frame 102 is provided in the middle of the inner wall of the housing 101. Four sliding grooves 104 are formed on both sides of the inner wall of the housing 101. A transmission screw 103 is provided directly below the sliding grooves 104. The transmission screw 103 is rotatably connected to the housing 101. A moving block 105 is provided on the outer wall of the transmission screw 103. The threaded hole at the bottom of the moving block 105 cooperates with the transmission screw 103. The moving block 105 is slidably connected to the sliding grooves 104. A sticker is provided on the top of the moving block 105. The bonding plate 106 is connected to the moving block 105 by a pin. The electric push rod 201 is set on both sides of the top of the support frame 102. The output end of the electric push rod 201 is provided with a connecting pipe 202. The inner side of the connecting pipe 202 is provided with a slot 203. The square tube is placed between the bonding plates 106. The motor is started. The motor drives the transmission screw 103 to rotate. The transmission screw 103 drives the moving block 105 to slide on the inner wall of the slide groove 104. Then the moving block 105 drives the bonding plate 106 to move and fit against the outer wall of the square tube to clamp and fix the square tube.
