Description

Technical Field

[0001] The invention belongs to the technical field of polishing equipment, in particular to a polishing equipment for automobile parts. Background Art

[0002] Auto parts are an important part of a car, also called auto accessories. Auto parts need to be deburred and polished during the production process to increase the brightness and smoothness of the auto parts surface. They will be deburred and polished by a vibration polisher. During polishing, the vibration polisher generates mechanical vibrations through a vibration motor, causing the entire device and the auto parts placed inside to vibrate slightly. The vibration motor is used to make the abrasive particles and parts move relative to each other, and friction and collision are used to achieve grinding, polishing, and deburring, ultimately making the surface of the parts smooth and bright. In the prior art, parts are placed in a polishing chamber filled with abrasive particles, and then the equipment is turned on to vibrate the vibration table through a vibration motor to remove burrs on the surface of the parts and polish the parts. However, during the deburring and polishing process, some parts have more burrs on the surface and need to be polished with larger abrasive particles. However, when the parts are finely polished after the burrs are removed, the larger abrasive particles will affect the polishing effect of the parts. If smaller abrasive particles are used, although the fine polishing effect of the parts is good, the use of smaller abrasive particles during deburring affects the deburring effect. For this reason, we propose a polishing equipment for automotive parts. Summary of the invention

The working end of the drive motor 209 is fixedly connected to the bottom of the main rotating rod 201. A second transmission belt 203 is sleeved between the three groups of main rotating rods 201. A second pulley is fixedly sleeved on the outside of the main rotating rod 201, and the second transmission belt 203 is sleeved on the second pulley.

[0021] In summary, different abrasive particles from large to small are placed in different polishing chambers 102 from left to right on the vibration table 100, and then the parts are placed in the leftmost polishing chamber 102, and then the locking screw 216 on the rotating circle 219 set on the third transmission belt 212 is first rotated and tightened in the direction close to the main rotating rod 201, so that the working end of the locking screw 216 contacts the main rotating rod 201, and then the locking screw 216 on the rotating circle 219 set on the upper transmission belt 405 is rotated outward and loosened, so that the working end of the locking screw 216 does not contact the main rotating rod 201, and then the driving motor 209 is turned on, and the driving motor 209 drives the corresponding main rotating rod 201 above to rotate, and the second transmission belt 203 is used to rotate.

[0022] Embodiment 2

[0023] Based on Example 1, please refer to Figure 1-Figure 10 The auxiliary polishing assembly includes a lower ring frame 207 and a mounting plate disposed above the polishing chamber 102. A plurality of fixed frames 213 are fixedly disposed on the top of the lower ring frame 207. An upper rotating ring 208 is rotatably disposed inside the fixed frame 213. The end of the mounting plate is fixed to the inner wall of the upper rotating ring 208. A plurality of rod bodies 210 are fixedly arranged inside the mounting plate, and polishing sandpaper 205 is arranged outside the rod bodies 210. The mesh numbers of the polishing sandpaper in different polishing chambers 102 are different. From the vibration table 100 to the right polishing chamber 102, there are coarse sandpaper, medium sandpaper and fine sandpaper, that is, low mesh number, medium mesh number and high mesh number, respectively. The low mesh number of the coarse sandpaper and the medium mesh number of the medium sandpaper increase the deburring and polishing effect on the parts, the fine sandpaper with high mesh number can increase the fine polishing effect on the parts, and the sandpaper with different mesh numbers can increase the polishing effect on the parts. The polishing sandpaper 205 can perform advanced polishing on the parts and increase the deburring and polishing effect on the parts. The polishing effect of the parts is improved. A rotating rod 215 is rotatably provided on the top of the lower ring frame 207. A transmission wheel 214 is fixedly sleeved on the outer part of the rotating rod 215. Two sets of rotating circles 219 are sleeved on the outer part of the main rotating rod 201. A support bearing 217 is sleeved on the outer part of the rotating circle 219. The outer wall of the support bearing 217 is fixedly connected to the rear frame 200. A third transmission belt 212 is sleeved between the fixed frame 213 and the transmission wheel 214. The outer part of the rotating circle 219 and the rotating rod 215 are sleeved and fixed with a third pulley. The third transmission belt 212 is sleeved on the outer part of the two sets of third pulleys. A support rod 218 is fixedly provided between the bottom of the lower ring frame 207 and the vibration table 100. The interior of the rotating circle 219 is connected with a locking screw 216 via threads, and the working end of the locking screw 216 extends to the surface of the main rotating rod 201 .

[0024] The present invention adopts a designed pre-polishing mechanism, and abrasive particles of different sizes are placed on the vibration table 100 from left to right in sequence. The parts are pre-deburred and polished in the two polishing chambers 102 from left to right in sequence, and finally enter the polishing chamber 102 on the far right for fine grinding and polishing, thereby increasing the deburring and polishing effect on the parts. In addition, during the pre-polishing and fine polishing process, the turntable 204 located in the polishing chamber 102 rotates to drive the abrasive particles and the parts to rotate, and the rod body 210 rotates in the opposite direction of the rotation of the abrasive particles and the parts to stir the abrasive particles, thereby increasing the grinding effect. At the same time, after the rotating parts contact the polishing sandpaper 205 outside the rod body 210, their surfaces can be further polished, thereby increasing the polishing effect on the outer surface of the parts.

[0025] In summary, the rotation of the main rotating rod 201 drives the rotating circle 219 located in the middle of the main rotating rod 201 to rotate, which in turn drives the third transmission belt 212, the rotating rod 215 and the transmission wheel 214 to rotate. The outer wall of the transmission wheel 214 contacts the outer wall of the upper rotating ring 208, thereby driving the upper rotating ring 208 to rotate. At this time, the upper rotating ring 208 rotates in the opposite direction to the rotation direction of the turntable 204, driving the mounting plate and the multiple rod bodies 210 on the mounting plate to rotate, thereby stirring the abrasive particles and increasing the grinding of the abrasive particles. The particles can grind, deburr and polish parts. When the multiple groups of rods 210 rotate, the polishing sandpaper 205 located outside the rods 210 can be driven to rotate. The rotating polishing sandpaper 205 contacts the surface of the parts, and the outer surface of the parts is polished and deburred by the polishing sandpaper 205, further increasing the deburring and polishing effect on the parts. Moreover, the three groups of polishing chambers 102 are all provided with polishing sandpaper 205, and the parts entering different polishing chambers 102 can be polished by the polishing sandpaper 205.

[0026] Embodiment 3

[0027] Based on Example 2, please refer to Figure 1-Figure 10 , a discharging piece is arranged on the top of the turntable 204, and the discharging piece includes a screw rod 401 rotatably arranged above the turntable 204 and a lower bracket 400 located on the upper surface of the turntable 204, the bottom of the lower bracket 400 contacts the upper surface of the turntable 204, and when the turntable 204 rotates, the lower bracket 400 is driven to rotate, and the lower bracket 400 is connected to the nut seat 402 through a lower bearing 403, which is convenient for the lower bracket 400 to rotate without affecting the subsequent ascending or descending movement of the lower bracket 400, a rotating shaft is arranged between the bottom of the screw rod 401 and the turntable 204, a nut seat 402 is arranged on the outer side of the bottom of the screw rod 401, a lower bearing 403 is fixedly arranged on the outside of the nut seat 402, and the lower bracket 400 is fixed on the outside of the lower bearing 403; A limiting rod 404 is provided inside the nut seat 402, and the limiting rod 404 will limit the nut seat 402 when it moves up and down. When the nut seat 402 moves up and down, it will move up and down on the limiting rod 404. The top of the limiting rod 404 is fixed on the lower ring frame 207. An upper transmission belt 405 is sleeved between the top of the screw rod 401 and the fixed frame 213. The outer part of the rotating circle 219 located at the top position of the main rotating rod 201 and the outer part of the top of the screw rod 401 are sleeved and fixed with a fourth pulley. The upper transmission belt 405 is sleeved on the outside of the two sets of fourth pulleys, and the longitudinal direction of the first pulley, the second pulley, the third pulley and the fourth pulley in the horizontal state is fixed. The cross-sections of the first transmission belt 202, the second transmission belt 203, the third transmission belt 212 and the upper transmission belt 405 are all inserted into the inner part of the outer edge of the "I"-shaped structure in different pulleys, so as to limit the first transmission belt 202, the second transmission belt 203, the third transmission belt 212 and the upper transmission belt 405, so as to avoid the deviation of the first transmission belt 202, the second transmission belt 203, the third transmission belt 212 and the upper transmission belt 405 during use, and increase the stability of the first transmission belt 202, the second transmission belt 203, the third transmission belt 212 and the upper transmission belt 405 during rotation.

[0028] The present invention has a designed discharge piece. When polishing in a polishing chamber 102 is completed and the next polishing chamber 102 is replaced, the lower bracket 400 is moved upward to lift the parts. At the same time, the abrasive particles on the lower bracket 400 fall off, making it convenient for personnel to take out the parts and put them into other polishing chambers 102 for further polishing, thereby facilitating operation.

[0029] In summary, after the parts in the first group of polishing chambers 102 are pre-deburred and polished, the locking screw 216 on the rotating circle 219 on which the third transmission belt 212 is sleeved is loosened outwardly so that the working end of the locking screw 216 is no longer in contact with the main rotating rod 201, and the locking screw 216 on the rotating circle 219 of the upper transmission belt 405 is rotated and locked in the direction close to the main rotating rod 201, so that the working end of the locking screw 216 is in contact with the main rotating rod 201. At this time, the upper transmission belt 405 and the screw rod 401 are driven to rotate by the rotation of the main rotating rod 201. At this time, the nut seat 402 at the bottom of the screw rod 401 rotates upward, driving the lower bearing 403 and the lower bracket 400 to move upward. During the upward movement, the lower bracket 400 contacts and drives the parts to move upward, and then the lower bracket 400 rises to the upper position of the polishing chamber 102. At the same time, during the upward movement of the lower bracket 400, the abrasive particles that fall on the lower bracket 400 are affected by the vibration of the vibrating table 100 and fall from the gap in the lower bracket 400 into the polishing chamber 102 below. When the lower bracket 400 moves upward to the top of the polishing chamber 102, parts are left on the lower bracket 400, and then the parts are placed in the lower bracket 400 above the polishing chamber 102 in the middle. Then, according to the opposite principle mentioned above, the drive motor 209 is reversed, indirectly driving the lower bracket 400 and the parts on the lower bracket 400 to descend into the polishing chamber 102 for polishing again. At this time, pre-deburring and polishing will continue with abrasive particles that are smaller than those in the leftmost polishing chamber 102. The above steps are repeated, and finally the parts enter the rightmost polishing chamber 102 and are finely polished with smaller abrasive particles to increase the polishing effect of the parts.

[0030] Embodiment 4

[0031] Based on Example 3, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig.11 and Fig.12 Three groups of dust absorbers are arranged above the vibration table 100. The dust absorbers include a tube body 300 fixed on the top of the vibration table 100 and a rail frame 303 fixed on the top of the vibration table 100. The inner wall of the tube body 300 is provided with multiple groups of suction ports 309. The suction ports 309 can suck in the dust floating above the polishing chamber 102. A slide plate 302 is slidably provided inside the rail frame 303, a cam 301 is fixedly provided outside the main rotating rod 201, a lower sliding platform 304 is slidably provided on the support rod 218, and multiple groups of cleaning brushes 305 are fixedly provided at the bottom of the lower sliding platform 304. The dust attached to the surface of the suction port 309 is cleaned by the cleaning brushes 305 that move up and down. An upper fixed platform 310 is fixedly provided on the support rod 218, and multiple groups of T-shaped columns 307 are fixedly provided at the bottom of the upper fixed platform 310. When the cleaning brush 305 moves up and down, it moves up and down on two groups of T-shaped columns 307, and the bottom of the T-shaped column 307 passes through the inside of the cleaning brush 305. Two groups of connecting springs 308 are fixedly provided between the bottom of the upper fixed platform 310 and the top of the lower sliding platform 304.

[0032] The dust absorber designed in the present invention can absorb the dust generated during the polishing process of parts and transport it to the dust removal equipment outside the equipment for dust removal and purification. At the same time, the rotation of the main rotating rod 201 can indirectly drive the cleaning brush 305 to move up and down, so that the cleaning brush 305 can clean the dust attached to the suction port 309, avoiding the accumulation of dust at the suction port 309 and causing blockage, so that the amount of dust sucked into the suction port 309 is stable, reducing the impact of dust on the on-site environment.

[0033] In summary, the tube body 300 is connected to an external dust removal device. When the equipment is in operation, a lot of dust will be generated. At this time, the dust removal device is turned on, and the vacuum pump in the dust removal device generates negative pressure, so that the multiple groups of suction ports 309 on the tube body 300 generate negative pressure, and the external dust is sucked in and transported to the dust removal device for purification. Since the suction port 309 will accumulate part of the dust on the surface area of ​​the suction port 309 during the dust inhalation process, it will easily cause the suction port 309 to be blocked over time. At this time, the rotating main rotating rod 201 drives the cam 301 to rotate, and the end of the cam 301 contacts and squeezes the slide plate 302, and the slide plate 302 will move in the direction close to the lower sliding platform 304. Since the end of the slide plate 302 close to the lower sliding platform 304 is an inclined surface structure, when the slide plate 302 moves in the direction of the lower sliding platform 304, the slide plate 302 is close to one end of the lower sliding platform 304. When the inclined surface of the lower sliding platform 304 contacts the lower sliding platform 304, it will push the lower sliding platform 304 to move in the downward direction, driving the multiple groups of cleaning brushes 305 below to move along. At this time, the cleaning brush 305 removes the dust attached to the surface of the suction port 309. At the same time, the downward movement of the lower sliding platform 304 will drive the connecting spring 308 to stretch. When the end of the rotating cam 301 disengages from the slide plate 302 and approaches one end of the main rotating rod 201, the connecting spring 308 is reset, driving the lower sliding platform 304 to move in the upward direction, and the lower sliding platform 304 drives the cleaning brush 305 to move upward and return to its original position. At this time, the upward movement of the lower sliding platform 304 will cause the slide plate 302 to move away from the lower sliding platform 304, and finally move to the original position. Repeating this process can enable the cleaning brush 305 to continuously move up and down to clean the dust at the suction port 309, thereby increasing the fluency of the dust inhaled by the suction port 309.

[0034] In this embodiment, a plurality of groups of shock-absorbing springs are arranged between the vibration table 100 and the base 101 , and vibration motors are fixedly arranged on both sides of the vibration table 100 .

[0035] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
