Description

Technical Field

[0002] A refrigerator is a refrigeration device that maintains a constant low temperature and is also a civilian product that keeps food or other items in a constant low temperature state. The refrigerator bottom plate belongs to an important accessory inside the refrigerator, and the refrigerator bottom plate has the characteristics of being thin, light, high in strength, and good in rigidity. At present, burrs will be generated at the edges of the bottom plate during the production and processing of the refrigerator bottom plate, and a grinding device is required to grind it.

[0003] Most of the existing grinding devices for the production and processing of refrigerator bottom plates directly grind the edges on both sides of the bottom plate after positioning the bottom plate. However, after grinding one side edge of the bottom plate, it is usually necessary to flip the bottom plate to grind the other side, resulting in excessive labor intensity. When the bottom plate is too large, it is more difficult to manually flip the bottom plate, which brings great trouble to the processing of the bottom plate. Moreover, after the grinding process, it is necessary to clean up the waste, increasing the processing procedures. Summary of the Invention

Detailed implementation manners

[0019] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0020] As Figures 1-12As shown in the figure, a grinding device for the production and processing of the refrigerator bottom plate body 7 includes a workbench 1 and a bottom plate body 7. In the middle of the upper end of the workbench 1, an arc-shaped groove 101 is opened. At the left and right ends of the upper end of the workbench 1, a first support plate 8 and a second support plate 9 are respectively and fixedly installed. At one end of the first support plate 8 and the second support plate 9 close to each other, a clamping device 4 is rotatably installed. The two ends of the bottom plate body 7 are clamped in the clamping devices 4 on both sides. At the upper part of the rear end of the workbench 1, a grinding device 2 is fixedly installed. At the left end of the workbench 1, a turning device 5 for driving the clamping device 4 to turn is fixedly installed. At the rear part on the left side of the workbench 1, a linkage device 3 is installed. The grinding device 2 drives the turning device 5 to work through the linkage device 3. During specific work, the bottom plate body 7 is fixed by the clamping device 4, and then the grinding device 2 grinds one side edge of the bottom plate body 7 from right to left. After one side edge is ground, the grinding device 2 drives the turning device 5 to work through the linkage device 3. The turning device 5 drives the clamping device 4 on the left side to turn by a certain degree, turns the edge on the other side of the bottom plate body 7 to face the grinding device 2 again, and then the grinding device 2 grinds the edge on the other side of the bottom plate body 7 from right to left, thus completing the grinding work. Moreover, during grinding, the bottom plate body 7 can be automatically turned over, reducing the labor intensity and improving the work efficiency.

[0021] At the lower part of the right end of the workbench 1, an activity groove 102 is opened. At the top of the activity groove 102, a collection port 103 communicating with the arc-shaped groove 101 is opened. A collection tank 6 is slidably connected in the activity groove 102. All the waste chips generated by grinding fall into the arc-shaped groove 101, and then are collected into the collection tank 6 through the collection port 103, reducing the trouble of manual cleaning of the chips generated by grinding. The inner wall of the arc-shaped groove 101 is made of smooth stainless steel material, and with the reciprocating movement of the arc-shaped scraping plate 211 (linked with the third support plate 26), the waste chips are efficiently scraped into the collection port 103. The collection tank 6 adopts a drawer-type sliding design (rails are embedded in the activity groove 102), with a capacity of 5L, and can continuously collect waste chips for 2 - 3 hours, reducing the frequency of shutdown for cleaning. The width of the collection port 103 (20 - 30mm) matches the curvature of the arc-shaped groove 101 to avoid the accumulation of large particle waste chips; the bottom inclination angle (15°) uses gravity to assist the waste chips to slide down to ensure smooth discharge.

[0022] The grinding device 2 includes two first fixing plates 21 and a forward and reverse motor 25. The two first fixing plates 21 are respectively fixedly installed at the left and right ends of the rear end of the workbench 1. A first screw rod 22 is rotatably installed between the two first fixing plates 21. A second sliding rod 23 is fixedly installed between the two first fixing plates 21. A first driving block 24 is threadedly connected to the outer surface of the first screw rod 22. The second sliding rod 23 penetrates through the first driving block 24 and is slidably connected to the first driving block 24. The forward and reverse motor 25 is fixedly installed on the right first fixing plate 21. A third support plate 26 is fixedly installed at the upper end of the first driving block 24. An electric telescopic rod 27 is fixedly installed at the front end of the third support plate 26. An installation plate 216 is fixedly installed at the front telescopic end of the electric telescopic rod 27. A grinding motor 28 is fixedly installed at the front end of the installation plate 216. A grinding wheel 29 is fixedly installed at the front output end of the grinding motor 28. A plurality of third limiting rods 215 are fixedly installed at the rear end of the installation plate 216. The rear ends of the third limiting rods 215 slidably penetrate through the third support plate 26 and are fixedly installed with a baffle. The arranged third limiting rods 215 are used to limit the installation plate 216 to prevent the installation plate 216 from displacing and affecting the grinding motor 28 from driving the grinding wheel 29 to work. A first toothed plate 214 is fixedly installed at the left end of the first driving block 24.

[0023] During specific operation, the forward and reverse motor 25 drives the first screw rod 22 to rotate. The first screw rod 22 drives the first driving block 24 to slide from right to left along the first sliding rod 48, thereby driving the third support plate 26 to move. The electric telescopic rod 27 on the support plate extends forward to drive the grinding motor 28 to move forward, driving the grinding wheel 29 close to the edge of the bottom plate body 7, and grinding the bottom plate body 7. Thus, the edge of the bottom plate body 7 can be continuously ground from right to left, with high working efficiency.

[0024] The grinding device 2 further includes an arc-shaped scraping plate 211. The arc-shaped scraping plate 211 is slidably connected to the inner wall of the arc-shaped groove 101.

The first connecting plate 210 is fixedly connected to the third support plate 26. A first convex block 213 is fixedly installed at the bottom of the second connecting plate 212. A first convex groove 104 is formed at the front side of the upper end of the workbench 1. The first convex block 213 slides in the first convex groove 104. The third support plate 26 drives the first connecting plate 210 to move, and the first connecting plate 210 drives the arc-shaped scraping plate 211 to move, scraping the debris in the landing arc-shaped groove 101, scraping the debris falling into the arc-shaped groove 101 along the arc-shaped surface into the collection port 103, and then collecting it into the collection tank 6, eliminating the need for subsequent cleaning of the debris.

[0025] The linkage device 3 includes a fifth support plate 31, which is fixedly installed at the rear of the left end of the workbench 1. A second driving rod 37 is rotatably installed in the middle of the fifth support plate 31. A second bevel gear 36 is fixedly installed at the rear end of the second driving rod 37.

A first bevel gear 35 is fixedly installed at the top of the second rotating rod 33. The first bevel gear 35 meshes with the second bevel gear 36. A first gear 34 is fixedly installed on the outer surface of the second rotating rod 33. The first toothed plate 214 can mesh with the first gear 34.

[0026] During specific operation, when the first driving block 24 moves from right to left, it drives the first toothed plate 214 to move from right to left. The first toothed plate 214 gradually approaches the first gear 34. Then, the laterally moving first toothed plate 214 drives the first gear 34 to rotate. The first gear 34 drives the second rotating rod 33 to rotate. The second rotating rod 33 drives the first bevel gear 35 to rotate. The first bevel gear 35 drives the second bevel gear 36 to rotate. The second bevel gear 36 drives the second driving rod 37 to rotate, thereby driving the flipping device 5 to work through the second driving rod 37. Similarly, when the first driving block 24 moves from left to right, the first toothed plate 214 drives the first gear 34 to rotate in the reverse direction, and further drives the second driving rod 37 to rotate in the reverse direction.

A fifth sliding rod 513 is fixedly installed at the right end of the slider 514. The two fifth sliding rods 513 slide through the second fixed plate 55 and are fixedly installed together with a third toothed plate 525. A third gear 526 is fixedly installed on the outer surface of the third driving rod 58. The third gear 526 is meshed with the third toothed plate 525.

The second limiting plate 510 and the first limiting plate 59 are fixedly installed on the front and rear sides of the left end of the workbench 1, and the second limiting plate 510 and the first limiting plate 59 are opposite and are distributed on the front and rear sides of the second fixed plate 55.On the front and rear sides of the upper end of the second fixed plate 55, a second limiting rod 512 and a first limiting rod 511 are respectively and fixedly installed. The tight contact design between the third limiting plate 524 and the third toothed plate 525 prevents them from disengaging from the third gear 526. The locking teeth 523 lock the second gear 520 during the non-flipping stage to avoid misoperation. The flipping angle of the present invention is precisely controlled by the screw pitch and the number of teeth of the gear (designed for 180° flipping) to ensure the precise alignment of the processing surfaces on both sides of the bottom plate body 7.

The first limiting rod 511 is opposite to the first inclined slot opening 594.

[0030] During specific operation, in the starting state, the first limiting rod 511 is within the first U-shaped card slot 593. When the grinding device 2 drives the second driving rod 37 to rotate, the second driving rod 37 drives the second screw rod 53 to rotate. The rotation of the second screw rod 53 drives the second driving block 54 to move from back to front. The second driving block 54 drives the second fixing plate 55 to move from back to front through the second convex block 56. The movement of the second fixing plate 55 drives the movement of the second toothed plate 521, and at the same time drives the third toothed plate 525 to move through the fifth slide rod 513. When the third toothed plate 525 moves, it drives the third gear 526 to rotate. The third gear 526 drives the third driving rod 58 to rotate. When the third driving rod 58 rotates, it drives the third screw rod 518 to rotate. The third screw rod 518 drives the third driving block 522 to move upward along the fourth slide rod 517, thereby driving the engaging teeth 523 away from the second gear 520 and releasing the restriction on the second gear 520. When the second toothed plate 521 contacts the second gear 520, the moving second toothed plate 521 drives the second gear 520 to rotate. The second gear 520 drives the fourth driving rod 519 to rotate. The fourth driving rod 519 drives the first rotating rod 41 to rotate, thereby completing the flipping of the clamping device 4. After driving the clamping device 4 to rotate 180 degrees, the second toothed plate 521 moves away from the second gear 520, and then drives the second limiting rod 512 into the second inclined slot 5104, and then slides into the second U-shaped card slot 5103 along the side wall of the second inclined slot 5104. While the second limiting rod 512 slides on the side wall of the second inclined slot 5104, it drives the second fixing plate 55 to gradually move away from the workbench 1, thereby driving the second toothed plate 521 away from the second gear 520. When the grinding device 2 drives the second driving rod 37 to rotate in the reverse direction, the second driving rod 37 drives the second screw rod 53 to rotate in the reverse direction, thereby driving the fixing plate to move from front to back through the second driving block 54. At the same time, it drives the third gear 526 to rotate in the reverse direction through the third toothed plate 525, thereby driving the third driving rod 58 to rotate in the reverse direction. Further, the third screw rod 518 drives the third driving block 522 to move downward, driving the engaging teeth 523 to approach the second gear 520 to restrict the second gear 520, avoiding the rotation of the clamping device 4 when grinding the bottom plate body 7 and affecting the grinding stability. When the second fixing plate 55 moves to the rear, it drives the first limiting rod 511 into the first inclined slot 594, and then slides into the first U-shaped card slot 593 along the side wall of the first inclined slot 594. While the first limiting rod 511 slides, it drives the second fixing plate 55 to reset to the original position. When the grinding device 2 finishes grinding one side of the bottom plate body 7, the present invention drives the flipping device 5 through the linkage device 3 to drive the clamping device 4 to flip, driving the bottom plate body 7 to flip, so that the other side of the bottom plate body 7 can be continuously ground, with high grinding efficiency and no need for manual flipping, improving work efficiency.

[0031] The clamping device 4 includes a first rotating rod 41. The two first rotating rods 41 are respectively rotatably installed at the middle parts of the mutually adjacent ends of the first support plate 8 and the second support plate 9. One end of the first rotating rod 41 is fixedly installed with a C-shaped plate 42. A positive and negative screw rod 43 is rotatably installed between the upper and lower walls of the C-shaped plate 42. The positive and negative threaded ends on the outer surface of the positive and negative screw rod 43 are respectively threadedly connected with a first clamping plate 44 and a second clamping plate 45. One side of the positive and negative screw rod 43 is provided with a first sliding rod 48. The first sliding rod 48 is fixedly installed on the inner wall of the C-shaped plate 42. The first sliding rod 48 is slidably connected with both the first clamping plate 44 and the second clamping plate 45. Rubber pads 47 are fixedly installed at the mutually adjacent ends of the first clamping plate 44 and the second clamping plate 45. The bottom plate body 7 is clamped between the first clamping plate 44 and the second clamping plate 45 which are distributed up and down. First driving rods 46 are rotatably installed at the upper and lower ends of the C-shaped plate 42. One end of the first driving rod 46 is fixedly connected with the end of the positive and negative screw rod 43 on the same side. A knob handle 49 is fixedly installed at the end of the first driving rod 46 away from the positive and negative screw rod 43.

[0032] During specific use, when the bottom plate body 7 needs to be polished, the two sides of the bottom plate body 7 are placed between the first clamping plate 44 and the second clamping plate 45 on both sides. Then, the knob handle 49 is rotated. The knob handle 49 drives the first driving rod 46 to rotate. The first driving rod 46 drives the positive and negative screw rod 43 to rotate. When the positive and negative screw rod 43 rotates, it drives the first clamping plate 44 and the second clamping plate 45 to approach each other, thereby clamping and fixing the bottom plate body 7, avoiding the movement of the bottom plate body 7 during polishing and affecting the polishing effect of the bottom plate body 7. In the present invention, the upper and lower clamping plates are synchronously closed by the positive and negative screw rod 43, and the clamping force is evenly distributed (the measured clamping force ≥ 200 N). The rubber pads 47 (with a thickness of 5 mm and a Shore hardness of 70A) provide flexible contact to avoid surface indentation of thin bottom plates (such as aluminum alloy plates with a thickness of 1 - 2 mm).

[0033] The length of the first rotating rod 41 at the left end is greater than the length of the first toothed plate 214, avoiding that before one side of the bottom plate body 7 is not completely polished by the polishing device 2, the first toothed plate 214 contacts the first gear 34 and drives the first gear 34 to rotate, thereby driving the flipping device 5 to perform flipping operation through the second rotating rod 33, the first bevel gear 35 and the second driving rod 37, which affects the polishing effect.

[0034] The working principle of the present invention is as follows: When in use, the refrigerator bottom plate body 7 is horizontally placed on the arc groove 101 of the workbench 1, ensuring that both ends are aligned with the clamping device 4. Manually rotate the knob handles 49 on both sides, and drive the upper and lower clamping plates to close synchronously through the positive and negative screw rods 43 to clamp the bottom plate. Then start the grinding device 2. The forward and reverse motor 25 drives the first screw rod 22 to rotate forward. The first screw rod 22 drives the first driving block 24 to slide from right to left along the first sliding rod 48, thereby driving the third support plate 26 to move. The electric telescopic rod 27 on the support plate extends forward to drive the grinding motor 28 to move forward, driving the grinding wheel 29 to approach the edge of the bottom plate body 7 to grind the bottom plate body 7, and then continuously grind the edge of the bottom plate body 7 from right to left. After the grinding wheel 29 finishes grinding the rightmost side of the bottom plate body 7, the grinding motor 28 stops working. Driven by the first screw rod 22, the second driving block 54 continues to move to the right, driving the first tooth plate 214 to gradually approach the first gear 34. Then the horizontally moving first tooth plate 214 drives the first gear 34 to rotate. The first gear 34 drives the second rotating rod 33 to rotate. The second rotating rod 33 drives the first bevel gear 35 to rotate. The first bevel gear 35 drives the second bevel gear 36 to rotate. The second bevel gear 36 drives the second driving rod 37 to rotate. Thus, the second driving rod 37 drives the second screw rod 53 to rotate through the second driving rod 37. The rotation of the second screw rod 53 drives the second driving block 54 to move from back to front. The second driving block 54 drives the second fixing plate 55 to move from back to front through the second convex block 56. The movement of the second fixing plate 55 drives the second tooth plate 521 to move. At the same time, it drives the third tooth plate 525 to move through the fifth sliding rod 513. When the third tooth plate 525 moves, it drives the third gear 526 to rotate. The third gear 526 drives the third driving rod 58 to rotate. When the third driving rod 58 rotates, it drives the third screw rod 518 to rotate. The third screw rod 518 drives the third driving block 522 to move upward along the fourth sliding rod 517, thereby driving the engaging teeth 523 away from the second gear 520 to release the restriction on the second gear 520. When the second tooth plate 521 contacts the second gear 520, the moving second tooth plate 521 drives the second gear 520 to rotate. The second gear 520 drives the fourth driving rod 519 to rotate. The fourth driving rod 519 drives the first rotating rod 41 to rotate, thus completing the flipping of the clamping device 4. After driving the clamping device 4 to rotate by a certain degree, the clamping device 4 drives the bottom plate body 7 to flip by a certain degree, so as to flip the other unground side for grinding. At this time, the second tooth plate 521 moves away from the second gear 520, and then drives the second limiting rod 512 into the second inclined slot 5104, and then slides into the second U-shaped card slot 5103 along the side wall of the second inclined slot 5104. While the second limiting rod 512 slides on the side wall of the second inclined slot 5104, it drives the second fixing plate 55 to gradually move away from the workbench 1, thereby driving the second tooth plate 521 to move away from the second gear 520, thus completing the grinding and flipping operation on one side of the bottom plate body 7; Then, the forward and reverse motor 25 operates to drive the first screw rod 22 to rotate in the reverse direction. The first screw rod 22 drives the first driving block 24 to slide from left to right along the first slide rod 48. When the first driving block 24 moves to the right, it drives the first toothed plate 214 to move to the right, thereby driving the first gear 34 to rotate in the reverse direction. The first gear 34 drives the second rotating rod 33 to rotate, the second rotating rod 33 drives the first bevel gear 35 to rotate, the first bevel gear 35 drives the second bevel gear 36 to rotate, and the second bevel gear 36 drives the second driving rod 37 to rotate. Thus, the second driving rod 37 drives the second screw rod 53 to rotate in the reverse direction through the second driving rod 37. Thereby, the fixing plate is driven to move from front to back through the second driving block 54. At the same time, the third toothed plate 525 drives the third gear 526 to rotate in the reverse direction, thereby driving the third driving rod 58 to rotate in the reverse direction. Further, the third screw rod 518 drives the third driving block 522 to move downward, driving the engaging teeth 523 to approach the second gear 520 to restrict the second gear 520. During the process of the fixing plate moving from front to back, the second toothed plate 521 does not contact the second gear 520. When the second fixing plate 55 moves to the rear, it drives the first limiting rod 511 to enter the first inclined slot 594, and then slides into the first U-shaped card slot 593 along the side wall of the first inclined slot 594. While the first limiting rod 511 slides, it drives the second fixing plate 55 to reset to the original position. At this time, the first toothed plate 214 just leaves the first gear 34. At the same time, the grinding wheel approaches the right side of the bottom plate body 7. Then, the grinding motor 28 is started to drive the grinding wheel 29 to perform grinding. During the process of the second driving block 54 moving from left to right, it drives the grinding wheel 29 to grind the side surface of the bottom plate body 7 from left to right, thereby completing the complete grinding process of the bottom plate body 7. The present invention can automatically grind the bottom plate body 7. At the same time, after grinding one side edge, it can automatically flip the bottom plate body 7 to grind the other side. The degree of automation is high and the working efficiency is high.
