Description

Technical Field

[0001] This invention relates to the field of automotive manufacturing machinery technology, specifically to a surface polishing device for automotive parts production. Background Technology

[0002] With the rapid development of the automotive industry, cars, as a popular means of transportation, are becoming increasingly favored by people. As people demand higher quality from cars, they also have higher requirements for their components to increase their stability and lifespan. In addition to these high requirements, the smoothness of the surfaces of automotive components is subject to strict requirements, necessitating polishing to meet these high demands. Chinese patent CN 214980040 U discloses a grinding device for automotive parts production. This device uses a sliding table, a slider, a lead screw, and a sliding motor to move the slider left and right. Automotive parts fixed to the slider by a fixing device also move with the slider. When the sliding motor rotates forward, it drives the lead screw to rotate forward, causing the slider, threaded onto the lead screw, to move to the left along the lead screw, and the automotive parts move to the left with the slider. When the sliding motor rotates in reverse, it drives the lead screw to rotate in reverse, causing the slider, threaded onto the lead screw, to move to the right along the lead screw, and the automotive parts move to the right with the slider. To fix the automotive parts, simply loosen the fixing bolts, place the automotive parts on a rectangular support plate, and then tighten the fixing bolts; the automotive parts are then fixed to the rectangular support plate. However, most car parts are large in size, so the surfaces that need to be polished are also large. Therefore, simply moving the slider in a horizontal direction cannot guarantee that all surfaces that need to be polished will be polished. It is necessary to remove the car parts multiple times, adjust their positions, and then fix them again in order to polish the remaining surfaces, which is very troublesome. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. In this invention, the automotive part to be polished is placed on a turntable. A servo motor is turned on to drive the lead screw to rotate. The rotation of the lead screw causes the slider to move along the slide groove, which in turn causes the support leg to move. The movement of the support leg causes the support plate to move. The movement of the support plate causes the hollow tube to move. The movement of the hollow tube causes the turntable to move, which in turn causes the automotive part to move, thus changing the polishing position. When the polishing position cannot be changed by adjusting the position of the automotive part horizontally, the throttle is turned to drive the connecting plate to rotate, which in turn causes the second rotating shaft to rotate. The rotation of the second rotating shaft drives the first rotating shaft to rotate through the pulley set. The rotation of the first rotating shaft drives the worm gear to rotate through the clamping strip and the clamping groove. The rotation of the worm gear drives the worm wheel to rotate, which in turn drives the hollow tube to rotate. The rotation of the hollow tube drives the turntable to rotate, which in turn causes the automotive part to rotate, thus changing the polishing position. 2. In this invention, the car parts are placed on a suction cup and a support platform. The suction cup is then attached to the bottom of the car parts. The three-way valve is opened to the end connected to the bellows. The circulating air pump is turned on to extract the gas from the suction cup through the three-way valve, bellows, connecting pipe, rotary joint, and hollow pipe, so that the suction cup adheres to the car parts more tightly under the action of air pressure difference. 3. In this invention, an air pipe is installed so that when the circulating air pump is turned on, airflow is blown out from the air pipe. A nozzle is installed to spray the airflow. The height of the mounting bracket is higher than the height of the turntable, and the nozzle is tilted downwards and facing the turntable. This allows the nozzle to blow the airflow to the grinding position and blow away the residue generated during grinding. 4. In this invention, after the automotive parts have been fixed in place, the three-way valve is opened to the pipe connected to the dust collection box. At this time, the circulating air pump works to draw outside air into the dust collection box through the three-way valve, and then discharges the gas into the air pipe to ensure continuous airflow to the grinding position. The air entering the dust collection box is filtered by the dust filter to remove dust, preventing dust from being blown to the grinding position. Attached Figure Description

The right end of the second rotating shaft 503 is rotatably connected to the left outer wall of the housing 1 via a bearing. The outer wall of the second rotating shaft 503 is fixedly connected to the inner wall of the driving wheel in the pulley set 501. The outer wall of the first rotating shaft 502 is fixedly connected to the inner wall of the driven wheel in the pulley set 501, so that rotating the second rotating shaft 503 can drive the first rotating shaft 502 to rotate via the pulley set 501. The first rotating shaft 502 passes through the outer wall of the housing 1 via a bearing, and a worm gear 5 is movably sleeved on the outer wall of the first rotating shaft 502. 09. A groove is provided on the inner wall of the worm 509. A retaining strip 508 is fixedly installed on the outer wall of the first rotating shaft 502. The retaining strip 508 is engaged in the groove. The retaining strip 508 and the groove allow the worm 509 to move left and right relative to the first rotating shaft 502, but the first rotating shaft 502 can still drive the worm 509 to rotate. A fixing block 507 is rotatably connected to the outer wall of the worm 509 through a bearing. The bottom of the outer wall of the fixing block 507 is fixedly connected to the top of the support plate 15. The worm 509 meshes with a worm wheel 506.

A slide groove 13 is provided on the top of the slide table 9, and a slider 12 is slidably arranged on the inner wall of the slide groove 13. A support leg 14 is fixedly installed on the top of the slider 12. The top of the support leg 14 is fixedly connected to the bottom of the support plate 15. The servo motor 10 drives the lead screw 11 to rotate. The rotation of the lead screw 11 drives the slider 12 to move along the slide groove 13, which in turn drives the support leg 14 to move. The movement of the support leg 14 drives the support plate 15 to move. A fixing mechanism 6 is provided on the top of the turntable 504, a slag blowing mechanism 7 is provided inside the outer shell 1, and a dust removal mechanism 8 is fixedly installed on the back of the outer shell 1. The car part to be polished is placed on the turntable 504. The servo motor 10 is turned on to drive the lead screw 11 to rotate. The rotation of the lead screw 11 drives the slider 12 to move along the slide groove 13, which in turn drives the support leg 14 to move. The movement of the support leg 14 drives the support plate 15 to move. The movement of the support plate 15 drives the hollow tube 505 to move. The movement of the hollow tube 505 drives the turntable 504 to move, which in turn drives the car part to move, changing the polishing position. When the polishing position cannot be changed by adjusting the position of the car part horizontally, the handle 16 is turned to drive the connecting plate 17 to rotate, which in turn drives the second rotating shaft 503 to rotate. The rotation of the second rotating shaft 503 drives the first rotating shaft 502 to rotate through the pulley group 501. The rotation of the first rotating shaft 502 drives the worm gear 509 to rotate through the clamping strip 508 and the clamping groove. The rotation of the worm gear 509 drives the worm wheel 506 to rotate, which in turn drives the hollow tube 505 to rotate. The rotation of the hollow tube 505 drives the turntable 504 to rotate, which in turn drives the car part to rotate, changing the polishing position.

[0019] In this embodiment, a housing door 2 is fixedly installed on the front of the housing 1 for taking out and putting in automotive parts. An observation window 3 is fixedly installed on the front of the housing door 2 for observing the polishing process. A support pad 4 is fixedly installed on the bottom of the housing 1 to support the overall device. Example 2

[0020] Based on Example 1, a preferred embodiment of the surface polishing apparatus for automotive parts production provided by the present invention is as follows: Figures 1 to 9As shown: The fixing mechanism 6 includes a circulating air pump 603, a support platform 606, and a suction cup 607. The bottom of the circulating air pump 603 is fixedly connected to the top of the slide table 9. A three-way valve 604 is connected to the air inlet of the circulating air pump 603. A bellows 605 is connected to one end of the three-way valve 604. A connecting pipe 601 is connected to the end of the bellows 605 away from the three-way valve 604. A rotary joint 602 is connected to the top of the connecting pipe 601. The top of the rotary joint 602 is connected to the hollow tube 505. The bottom of the suction cup 607 is fixedly connected to the top of the turntable 504, and the interior of the suction cup 607 is connected to the interior of the hollow tube 505. The bottom of the support platform 606 is fixedly connected to the top of the turntable 504. The suction cup 607 is used to adsorb and fix the car parts. The height of the support platform 606 is lower than the height of the suction cup 607, so that the support platform 606 can both adsorb and fix the car parts. The support platform 606 does not hinder the suction cup 607 from adsorbing the car parts. There are multiple support platforms 606 and suction cups 607, which are arranged in a circumferential array on the top of the turntable 504. The support platform 606 is set to lift the car parts upward to prevent the car parts from crushing the suction cup 607. The multiple sets of suction cups 607 make the suction cup 607 adsorb the car parts more stably. The circulating air pump 603 is set to extract the gas in the suction cup 607 through the three-way valve 604, bellows 605, connecting pipe 601, rotary joint 602, and hollow pipe 505, so that the suction cup 607 adsorbs the car parts more tightly under the action of air pressure difference. The rotary joint 602 allows the hollow pipe 505 to rotate relative to the connecting pipe 601. The bellows 605 is set so that when the hollow pipe 505 is moved by the support plate 15, the bellows 605 stretches or contracts to ensure the connection between the three-way valve 604 and the connecting pipe 601. The car part is placed on the suction cup 607 and the support platform 606. The suction cup 607 is then attached to the bottom of the car part. The three-way valve 604 is opened to the end connected to the bellows 605. The circulating air pump 603 is turned on to extract the gas from the suction cup 607 through the three-way valve 604, the bellows 605, the connecting pipe 601, the rotary joint 602, and the hollow pipe 505. This makes the suction cup 607 adhere to the car part more tightly under the action of air pressure difference. Example 3

[0021] Based on Examples 1 and 2, a preferred embodiment of the surface polishing apparatus for automotive parts production provided by the present invention is as follows: Figures 1 to 9As shown: The slag blowing mechanism 7 includes a fixed frame 701. The bottom of the fixed frame 701 is fixedly connected to the top of the slide table 9. A fixed sleeve 703 is fixedly installed on the outer wall of the fixed frame 701. The fixed frame 701 and the fixed sleeve 703 fix the air pipe 702. The air pipe 702 is fixedly installed on the inner wall of the fixed sleeve 703. The bottom end of the air pipe 702 is connected to the air outlet of the circulating air pump 603. A nozzle 704 is connected to the top end of the air pipe 702. The air pipe 702 is configured so that when the circulating air pump 603 is turned on, airflow will be blown out from the air pipe 702. The nozzle 704 sprays the airflow. The height of the fixed frame 701 is higher than the height of the turntable 504. The nozzle 704 is tilted downward and faces the turntable 504. This allows the nozzle 704 to blow the airflow to the grinding position and blow away the residue generated during grinding. Example 4

[0022] Based on Examples 1 and 3, a preferred embodiment of the surface polishing apparatus for automotive parts production provided by the present invention is as follows: Figures 1 to 9 As shown: The dust removal mechanism 8 includes a dust collection box 801.

The L-shaped plate 21, the fixing plate 18, and the bolt 22 are used to fix the protective net 805 inside the dust collector 801. An insertion hole 19 is provided at the bottom of the dust collector 801, and an insertion rod 20 is fixedly installed at the bottom of the protective net 805. The insertion rod 20 is inserted into the insertion hole 19. 9. To prevent the bottom of the protective net 805 from lifting, after the car parts have been fixed, open the three-way valve 604 to the pipe connected to the dust collection box 801. At this time, the circulating air pump 603 works to draw outside air into the dust collection box 801 through the three-way valve 604, and then discharges the gas into the air pipe 702 to ensure continuous airflow to the grinding position. The air entering the dust collection box 801 is filtered by the dustproof net 804 to remove dust, preventing dust from being blown to the grinding position.
