Description

Technical Field

[0001] This utility model relates to sheet metal processing equipment, specifically to a device for uniformly grinding and polishing the inner and outer surfaces of formed sheet metal parts. Background Technology

[0002] Sheet metal parts are components made from sheet metal through processes such as punching, bending, and stretching, and are widely used in various industries. They come in a variety of material types, and processing techniques include shearing, punching, and bending, while surface treatments include polishing and painting. Precision and tolerances are crucial to the performance of sheet metal parts, and design must consider material properties and processing techniques. Assembly methods for sheet metal parts include welding and riveting, the choice of which depends on materials and dimensions. With increasing attention to environmental impact, the sustainability of sheet metal parts is becoming increasingly important, including the use of recyclable materials and reduction of waste and energy consumption.

[0003] Most existing sheet metal grinding and polishing equipment can only grind and polish one side at a time, which means that repeated operations are required when processing two sides. This is not only time-consuming, but also prone to poor processing results due to the need to manually flip the workpiece. It may even lead to problems such as inaccurate workpiece positioning and uneven surface treatment. Utility Model Content

[0033] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0034] Reference Figures 1-6 As shown, a device for uniformly grinding and polishing the inner and outer surfaces of formed sheet metal parts includes a support mechanism 1. Two symmetrically distributed clamping mechanisms 4 are provided at the top and bottom inner sides of the support mechanism 1, and a conveying mechanism 2 is provided on the right side of the support mechanism 1.

[0035] The support mechanism 1 includes two support plates 101, and four evenly distributed support columns 102 are fixedly connected between the two support plates 101.

[0036] The conveying mechanism 2 includes a U-shaped plate 201 fixedly installed on the right side of the support plate 101 and a telescopic cylinder 202 that passes through and is connected to the upper end of the U-shaped plate 201.

[0037] The clamping mechanism 4 includes a screw 404 rotatably connected to the inside of the support plate 101 and a second slider 408 threadedly connected to the outer surface of the telescopic cylinder 202. The bottom side of the second slider 408 is slidably connected to the inside of the support plate 101, and a driven roller 405 is rotatably connected to the upper surface of the second slider 408. A first slider 403 is rotatably connected to the upper end of the driven roller 405. The screw 404 is threadedly connected to the inside of both the first slider 403 and the second slider 408. A limit cover 401 is provided on the upper end of the outer surface of the driven roller 405. A protective cover 402 is fixedly installed on the upper surface of the limiting cover 401. The upper side of the outer surface of the slider 403 is slidably connected to the inner wall of the protective cover 402, and the lower side of the outer surface of the slider 403 is slidably connected to the inner wall of the protective cover 402. A timing belt 406 is fitted on the outer surface of each of the two driven rollers 405. A motor 407 is fixedly installed on the upper surface of the limiting cover 401. The output end of the motor 407 passes through the upper end of the limiting cover 401 and is fixedly connected to the upper end of the driven roller 405 on the side away from the protective cover 402.

[0038] Specifically, the support column 102 supports the upper support plate 101, and the support column 102 connects the two support plates 101 together. The upper support plate 101 then supports and fixes the conveying mechanism 2, and the two support plates 101 fix the clamping mechanism 4. The support plates 101 restrict the screw 404 in the clamping mechanism 4, ensuring that the screw 404 can only rotate inside the support plate 101. Simultaneously, the slider 408 sliding inside the support plate 101 adjusts the position of one driven roller 405. Then, the motor 407 above the other driven roller 405 drives the driven roller 405 to rotate. The limiting cover 401 fixes the motor 407, and then drives the timing belt 406 to rotate through the driven roller 405, thereby facilitating the transportation of the workpiece. At the same time, the screw 404 inside the rotating support plate 101 and the protective cover 402 drives the slider 1 403 and slider 2 408 to slide, thereby driving the driven roller 405 to slide between the support plate 101 and the limiting cover 401. This allows the position of one of the driven rollers 405 to be adjusted, which is convenient for adjusting the tension of the timing belt 406 according to the workpiece. Meanwhile, the driven rollers 405 at both ends of the limiting cover 401 fix and limit the limiting cover 401, preventing the limiting cover 401 from shifting or falling off during use.

[0039] Reference Figures 1-5 As shown, buffer mechanisms 5 are fixedly installed on the bottom and top sides of both timing belts 406. Each buffer mechanism 5 includes a fixing plate 501 fixedly installed on both the top and bottom sides of the timing belt 406. The fixing plate 501 has symmetrically distributed sliding holes 504 inside. A T-shaped post 502 is slidably connected inside the sliding holes 504, with one end of the T-shaped post 502 located at the rear side of the fixing plate 501. A fixing post 503 is slidably connected to the outer surface of the T-shaped post 502, with the rear side of the fixing post 503 connected to the front side of the fixing plate 501. The T-shaped column 502 is fitted with a spring 506 on its outer surface. One end of the spring 506 is fixedly installed on the front side of the fixed column 503, and the other end of the spring 506 is fixedly installed with a contact plate 507. The rear side of the contact plate 507 is connected to the front end of the T-shaped column 502. Both sides of the fixed column 503 are rotatably connected with connecting rods 505. The end of the connecting rod 505 away from the fixed column 503 is rotatably connected with a push rod 508. The end of the push rod 508 near the contact plate 507 is rotatably connected to the rear side of the contact plate 507.

[0040] Specifically, the timing belt 406 drives the buffer mechanism 5 to move, thereby clamping the workpiece through two facing buffer mechanisms 5. The contact plate 507 is in close contact with the surface of the workpiece. As the buffer mechanism 5 moves, the workpiece squeezes the contact plate 507, causing the contact plate 507 to move outward, thereby squeezing the spring 506 and causing the spring 506 to contract. At the same time, the T-shaped column 502 restricts the spring 506 and the contact plate 507, so that they can only move along the axial direction of the T-shaped column 502. The connecting rod 505 and the push rod 508 further restrict the contact plate 507 to prevent it from moving with the workpiece. This allows for stable clamping and fixing of the workpiece, preventing displacement of the workpiece during grinding and polishing, which would affect the grinding effect.

[0041] Reference Figure 6 As shown, the output end of the telescopic cylinder 202 passes through the upper end of the U-shaped plate 201 and is connected to the mounting block 203. Multiple symmetrical clamping arms 205 are rotatably connected to the outer surface of the mounting block 203. The upper and lower clamping arms 205 are connected by a synchronizing rod 206. A mini cylinder 204 is fixedly installed at the bottom end of the synchronizing rod 206. The output end of the mini cylinder 204 is fixedly installed at the bottom end of the synchronizing rod 206.

[0042] Specifically, the mini cylinder 204 at the bottom of the synchronizing rod 206 drives the two synchronizing rods 206 to move towards the center. When the clamping arm 205 connected to one of the synchronizing rods 206 touches the workpiece, it stops moving, causing the other clamping arm 205 to move towards the center under the drive of the mini cylinder 204. Thus, the mini cylinder 204 can drive the clamping arm 205 to clamp the workpiece. Simultaneously, the mounting block 203 restricts the end of the clamping arm 205 near the mounting block 203, ensuring that only the end of the clamping arm 205 away from the mounting block 203 can move towards the center. The workpiece can be clamped by the clamping arm 205, and then the mounting block 203 can be moved up and down by the telescopic cylinder 202 above the U-shaped plate 201, so that the clamped workpiece can be transported from the lower buffer mechanism 5 to the upper buffer mechanism 5. At the same time, the workpiece is clamped by the buffer mechanism 5 to prevent it from falling off. Then, the clamping mechanism 4 on the upper support plate 101 drives the workpiece to move in the opposite direction to the clamping mechanism 4 on the lower support plate 101, so that the lower inner and outer sides of the workpiece can be ground.

[0043] Reference Figure 7 As shown, a fixing block 6 is fixedly installed on one side of each of the two support plates 101, a rotary motor 3 is fixedly installed between the two fixing blocks 6, and a grinding disc 7 is fixedly installed at the output end of each of the two rotary motors 3.

[0044] Specifically, the rotary motor 3 is fixed by two fixing blocks 6, and the rotary motor 3 drives the grinding disc 7 to rotate. The two counter-rotating grinding discs 7 can counteract the torque generated during grinding, thereby making the workpiece transport more smoothly.

[0045] Working principle: In use, the two motors 407 above the limit cover 401 are started. The motors 407 drive the driven roller 405 and the spring 506 on the outside of the driven roller 405 to rotate. At the same time, the position of the driven roller 405 is adjusted by rotating the screw 404 at the other end of the limit cover 401 and the screw 404 on the support plate 101. The screws 404 drive the slider 403 inside the protective cover 402 and the slider 408 inside the support plate 101 to move, which in turn drives the driven roller 405 to slide along the direction of the limit cover 401. This allows the position of the driven roller 405 to be adjusted, thereby adjusting the tension of the timing belt 406.

[0046] The timing belt 406 drives the buffer mechanism 5 to move. The workpiece is fixed by the contact plate 507 on the buffer mechanism 5. The two contact plates 507 squeeze the workpiece, causing the contact plate 507 to squeeze the spring 506, causing the spring 506 to contract. At the same time, it pushes the T-shaped column 502 to move towards the fixed plate 501. Meanwhile, the connecting rods 505 and push rods 508 on both sides of the contact plate 507 restrict the position of the contact plate 507, so that the contact plate 507 can only slide horizontally and cannot rotate axially. This achieves the effect of fixing and conveying the workpiece, which is then transported forward by the timing belt 406.

[0047] When transported to the middle of the support plate 101, the two rotary motors 3 drive the two opposing grinding discs 7 to rotate in opposite directions, so that the upper inner and outer sides of the workpiece can be ground and polished by the rotating grinding discs 7, and then continue to be transported by the timing belt 406.

[0048] When the workpiece is transported to the end furthest from the motor 407, the buffer mechanism 5 moves to both sides following the timing belt 406, thereby loosening the clamping of the workpiece. At the same time, the mini cylinder 204 at the lower end of the synchronizing rod 206 drives the two synchronizing rods 206 to move towards the middle, which in turn drives the two clamping arms 205 near the end of the limit cover 401 to move towards the middle, thereby clamping the workpiece. Then, the telescopic cylinder 202 drives the mounting block 203 and the clamped workpiece to move upward. Subsequently, the upper clamping mechanism 4 and the buffer mechanism 5 clamp and transport the workpiece. At the same time, the clamping mechanism 4 drives the workpiece to be transported in the opposite direction. Meanwhile, the grinding disc 7 grinds and polishes the lower end of the workpiece, thereby grinding and polishing both the inner and outer sides of the lower end of the workpiece. This allows for fully automatic processing of the workpiece, and then the workpiece is sent out.
