Description

Technical Field

[0001] This invention relates to the field of battery pallet processing equipment, and in particular to an automotive battery pallet cutting machine tool. Background Technology

[0002] Car batteries face various complex environments during use, such as dust and moisture. As a support and protection component for the battery, the battery tray can, to a certain extent, prevent external impurities from directly contacting the battery, reducing the risk of battery seal failure due to impurity intrusion.

[0003] In the manufacturing process of battery trays, the sealing groove is a key structure to ensure the sealing performance of the battery. Currently, the edges of the sealing groove often have problems such as unevenness, excess scrap, and surface roughness that do not meet requirements during manufacturing. Traditional cutting equipment is difficult to cut precisely along the edge of the sealing groove, and cannot guarantee the accuracy of the edge dimensions and the smoothness of the surface. Moreover, burrs may remain after cutting, affecting the sealing effect. In addition, a lot of heat is generated during the cutting process. This heat not only causes thermal deformation of the material, further affecting the dimensional accuracy and sealing performance of the sealing groove, but also continues to have adverse effects on the workpiece after cutting. Furthermore, an oxide layer may be generated after cutting in a high-temperature environment. The presence of the oxide layer will change the surface flatness and dimensional accuracy of the sealing groove edge. Uneven thickness may cause the sealing groove and the sealing element to not achieve good adhesion, thereby reducing the sealing performance of the battery tray, increasing the risk of battery leakage, and causing problems such as decreased coating adhesion and coating peeling.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This automotive battery tray cutting machine tool, during the grinding process, uses a pump to deliver epoxy coating coolant from the water tank to the connecting sleeve through a second connecting pipe and a first connecting pipe. The liquid flows downward along the spiral groove on the side wall of the spraying rod, and the spraying rod rotates synchronously with the grinding rod. Centrifugal force throws the liquid out and sprays it onto the grinding area. This process not only removes the heat generated by cutting and grinding in time, effectively reducing the thermal deformation of the material and ensuring the dimensional accuracy and sealing performance of the sealing groove, but also inhibits the formation of an oxide layer. This avoids the oxide layer damaging the edge flatness, dimensional accuracy, and sealing performance of the sealing groove. Reducing the formation of an oxide layer also reduces a series of subsequent problems caused by the oxide layer. During coating, the coating adhesion is enhanced, reducing problems such as coating peeling and improving the overall processing quality.

[0018] This automotive battery tray cutting machine features a grinding process where multiple fifth electric telescopic rods drive a grinding rod to accurately approach the edge of the sealing groove, while a fourth motor drives the grinding rod to rotate at high speed and stably. Simultaneously, a third motor drives a second rotating block to rotate at an adjustable angle, grinding the flat surface of the cut area and the lower edge of the chamfer. The fifth electric telescopic rods extend and retract as needed based on the grinding progress, ensuring uniform contact pressure between the grinding rod and the edge of the sealing groove. This effectively improves the surface smoothness of the sealing groove edge, solving the problems of insufficient surface roughness and residual burrs in traditional processing, thus providing a strong guarantee for the battery's sealing performance.

[0031] In this embodiment, the adjustment mechanism 3 includes a second lower pressure plate 31 fixedly connected to one end of a first lower pressure plate 24. Two third electric sliding grooves 32 are opened on the bottom side wall of the second lower pressure plate 31.

A guide plate 34 is provided on the bottom side wall of the two third electric sliders 33. A first motor 36 is provided on the top side wall of the guide plate 34. A first transmission shaft 37 is provided through the guide plate 34 at the output end of the first motor 36.

An opening is opened on the other side wall of the movable frame 38 and multiple third electric telescopic rods 39 are provided on the inner wall. The telescopic ends of the multiple third electric telescopic rods 39 are fixedly connected to the same movable plate 391. A second slot 35 for the first motor 36 to move is opened on the top side wall of the second lower pressure plate 31.

[0032] Specifically, the third electric slider 33 slides within the third electric slide groove 32, causing the guide plate 34 to move laterally. The first motor 36 starts and drives the moving frame 38 to rotate via the first transmission shaft 37. At the same time, the lateral position of the moving plate 391 can be adjusted, allowing for full coverage of the battery tray. Meanwhile, the first sensor 44 monitors the relative position of the cutting head 492 and the tray in real time. Through the extension and retraction of multiple third electric telescopic rods 39, the front and rear positions of the moving plate 391 are precisely adjusted.

[0033] In this embodiment, the grinding mechanism 5 includes a second fixed plate 51 fixedly connected to one side wall of a movable plate 391. A plurality of fifth electric telescopic rods 52 are provided on the top side wall of the second fixed plate 51. The telescopic ends of the plurality of fifth electric telescopic rods 52 pass through the second fixed plate 51 and are provided with a connecting plate 5993. Two second rotating plates 53 are provided on the bottom side wall of the connecting plate 5993. A third motor 54 is provided on one side wall of one second rotating plate 53. A third drive shaft 55 is provided at the output end of the third motor 54. The outer side wall of the other end of the third drive shaft 55 is rotatably connected to the other second rotating plate 53. A second rotating block 56 is fixedly connected to the outer side wall of the third drive shaft 55. The second rotating block 56 is located between the two second rotating plates 53.

[0034] Specifically, multiple fifth electric telescopic rods 52 extend, causing the connecting plate 5993 to descend and drive the grinding rod 592 to approach the edge of the sealing groove. When the distance is appropriate, the fifth electric telescopic rods 52 stop extending. At this time, the third motor 54 starts and drives the second rotating block 56 to rotate through the third transmission shaft 55, adjusting the angle of the housing 57 so that the grinding rod 592 contacts the chamfered edge of the sealing groove.

[0035] In this embodiment, a housing 57 is provided on the bottom side wall of the second rotating block 56. A T-shaped hole is opened on the bottom side wall of the housing 57 and a T-shaped rotating sleeve 58 is rotatably connected thereto. A connecting sleeve 5991 is detachably connected to the inner side wall of the T-shaped rotating sleeve 58. A fourth motor 59 is provided on the top side wall of the housing 57. A fourth transmission shaft 591 is provided through the output end of the fourth motor 59 through the housing 57. A transmission bar 595 is connected to the outer side wall of the fourth transmission shaft 591 and the outer side wall of the T-shaped rotating sleeve 58. A grinding rod 5922 is provided on the bottom side wall of the connecting sleeve 5991.

[0036] Specifically, the fourth motor 59 starts, driving the T-shaped rotating sleeve 58 to rotate via the fourth transmission shaft 591 and transmission bar 595, thereby rotating the grinding rod 592 to grind the chamfered edge of the sealing groove. The second rotating block 56 rotates to adjust the angle of the housing 57 to grind the lower edge of the chamfer. During the grinding process, the fifth electric telescopic rod 52 extends and retracts appropriately according to the grinding situation to ensure uniform contact pressure between the grinding rod 592 and the edge of the sealing groove, thereby improving the grinding quality.

[0037] In this embodiment, a third groove 5992 is provided on the bottom side wall of the polishing rod 592. A spraying rod 593 is fixedly connected to the inner side wall of the third groove 5992. A spiral groove 594 is spirally provided on the outer side wall of the spraying rod 593. An opening is provided on the side wall of the housing 57 and a first connecting pipe 596 is fixedly connected to it. The first connecting pipe 596 communicates with the connecting sleeve 5991. A water tank 599 is fixedly connected to one side of the moving frame 38. An opening is provided on the front side wall of the water tank 599 and a pump body 598 is fixedly connected to it. A second connecting pipe 597 is provided at the output end of the pump body 598. The other end of the second connecting pipe 597 is fixedly connected to the other end of the first connecting pipe 596.

[0038] Specifically, when the pump body 598 is started, the epoxy coating coolant in the water tank 599 is transported to the connecting sleeve 5991 through the second connecting pipe 597 and the first connecting pipe 596. The liquid flows downward along the spiral groove 594 on the side wall of the spraying rod 593, and the spraying rod 593 rotates synchronously with the grinding rod 592. When the liquid reaches the end of the spiral groove 594, it is thrown out by centrifugal force and sprayed on the grinding area to cool, lubricate and reduce oxidation.

[0039] In this embodiment, the cutting mechanism 4 includes a plurality of fourth electric slide grooves 41 opened on one side wall of the moving plate 391. A fourth electric slider 42 is slidably connected to the inner side of the fourth electric slide groove 41. A mounting plate 43 is fixedly connected to the side wall of the fourth electric slider 42 away from the moving plate 391. A first sensor 44 is provided on the front side wall of the mounting plate 43.

[0040] Specifically, the fourth electric slider 42 slides within the fourth electric slide groove 41, causing the mounting plate 43 to move toward the tray, so that the cutting head 492 gradually approaches the edge of the sealing groove. The first sensor 44 continuously monitors the distance, and when the preset value is reached, the fourth electric slider 42 stops moving.

[0041] In this embodiment, two first rotating plates 47 are provided on the bottom side wall of the mounting plate 43. A second motor 45 is provided at one end of one first rotating plate 47. A second drive shaft 46 is provided at the output end of the second motor 45. The outer side wall of the other end of the second drive shaft 46 is rotatably connected to the other first rotating plate 47. A first rotating block 48 is fixedly connected to the outer side wall of the second drive shaft 46. The first rotating block 48 is located between the two first rotating plates 47. A second sensor 49 is provided on the front side wall of the first rotating block 48. A fourth electric telescopic rod 491 is provided on the bottom side wall of the first rotating block 48. A cutting head 492 is provided at the telescopic end of the fourth electric telescopic rod 491.

[0042] Specifically, the second motor 45 starts and drives the first rotating block 48 to rotate through the second transmission shaft 46, adjusting the cutting angle of the cutting head 492. The second sensor 49 monitors the angle in real time and provides feedback to ensure the angle is accurate. The fourth electric telescopic rod 491 extends, causing the cutting head 492 to contact the edge of the sealing groove and begin cutting, cutting the edge of the battery tray sealing groove into a 45-degree chamfer.

[0043] In this embodiment, each of the two first lower pressure plates 24 is provided with a fixing rod 25 on its bottom sidewall. Each of the fixing rods 25 has a first slot 26 at its bottom end. The inner wall of the top of the first slot 26 is provided with a first electric telescopic rod 27. The telescopic end of the first electric telescopic rod 27 is provided with a clamping rod 28. The clamping rod 28 fits into the first slot 26. The outer sidewall of the clamping rod 28 has multiple holes arranged in a circumferential array and is fixedly connected to a second electric telescopic rod 29. Each of the telescopic ends of the multiple second electric telescopic rods 29 is provided with a clamping plate 291. The other sidewall of the clamping plate 291 is in contact with the inner sidewall of the frame block.

[0044] Specifically, the second electric slider 23 in the second electric slide 22 is activated, causing the first lower pressure plate 24 to move towards the battery tray. The first electric telescopic rod 27 extends, pushing the clamping rod 28 out of the first slot 26 and inserting it into the inside of the frame block. Subsequently, multiple second electric telescopic rods 29 extend, pushing the clamping plate 291 towards the inner wall of the frame block until the clamping plate 291 is in close contact with the inner wall of the frame block. At this time, each clamping plate 291 applies pressure evenly, firmly clamping the battery tray in a fixed position to prevent shaking during subsequent processing.

[0045] In this embodiment, the bottom sidewalls of the two fixed frames 1 are provided with a base plate 13, and the top sidewalls of the base plate 13 are provided with a plurality of support frames 14. The sidewalls of the corresponding ends of the fixed frames 1 are symmetrically rotatably connected with a plurality of conveying wheels 15. The height of the conveying wheels 15 is higher than that of the support frames 14 and they are in contact with the bottom of the battery tray.

[0046] Specifically, the battery tray is transported by multiple conveyor wheels 15. After the battery tray is transported to the corresponding position on the upper end of the conveyor wheels 15, the first electric slider 17 in the first electric chute 16 is activated.

[0047] In this embodiment, a first electric sliding groove 16 is provided at one end of the fixed frame 1, and a first electric slider 17 is slidably connected to the inner side of the multiple first electric sliding grooves 16. A positioning plate 12 is provided at one end of the multiple first electric sliders 17.

[0048] Specifically, the first electric slider 17 drives the positioning plate 12 to move toward the battery tray. After one side of the positioning plate 12 contacts the outer wall of the frame block, the first electric slider 17 and the multiple conveying wheels 15 stop moving, completing the initial positioning of the battery tray and ensuring that the tray is in the appropriate position in the horizontal direction.

[0049] It should be noted that this invention is a car battery tray cutting machine. The user places the battery tray to be processed onto the machine tool, and the battery tray is transported by multiple conveyor rollers 15. After the battery tray is transported to the corresponding position on the upper end of the conveyor rollers 15, the first electric slider 17 in the first electric slide 16 is activated. The first electric slider 17 drives the positioning plate 12 to move towards the battery tray. When one side of the positioning plate 12 contacts the outer wall of the frame block, the first electric slider 17 and the multiple conveyor rollers 15 stop moving, completing the initial positioning of the battery tray and ensuring that the tray is in the horizontal direction. Once the battery tray is in the correct position, the second electric slider 23 in the second electric slide 22 is activated, causing the first lower pressure plate 24 to move towards the battery tray. Then, the first electric telescopic rod 27 extends, pushing the clamping rod 28 out of the first slot 26 and inserting it into the inside of the frame block. Subsequently, multiple second electric telescopic rods 29 extend, pushing the clamping plate 291 towards the inner wall of the frame block until the clamping plate 291 is in close contact with the inner wall of the frame block. At this time, each clamping plate 291 applies pressure evenly, firmly clamping the battery tray in a fixed position to prevent shaking during subsequent processing.

[0050] Subsequently, the adjustment mechanism 3 begins operation. The third electric slider 33 slides within the third electric slide groove 32, causing the guide plate 34 to move laterally. The first motor 36 starts, driving the moving frame 38 to rotate via the first transmission shaft 37. Simultaneously, the lateral position of the moving plate 391 can be adjusted, allowing for full coverage of the battery tray. Meanwhile, the first sensor 44 monitors the relative position of the cutting head 492 and the tray in real time. Multiple third electric telescopic rods 39 extend and retract, precisely adjusting the front-to-back position of the moving plate 391 to ensure the cutting head 492 accurately reaches the cutting start position. The fourth electric slider 42 slides within the fourth electric slide groove 41, moving the mounting plate 43 towards the tray, gradually bringing the cutting head 492 closer to the edge of the sealing groove. The first sensor 44 continuously monitors the distance; when a preset value is reached, the fourth… When the electric slider 42 stops moving, the second motor 45 starts, driving the first rotating block 48 to rotate via the second transmission shaft 46, adjusting the cutting angle of the cutting head 492. The second sensor 49 monitors the angle in real time and provides feedback to ensure accuracy. The fourth electric telescopic rod 491 extends, causing the cutting head 492 to contact the edge of the sealing groove and begin cutting, creating a 45-degree chamfer on the edge of the battery tray sealing groove. Simultaneously, multiple fifth electric telescopic rods 52 extend, causing the connecting plate 5993 to descend and bringing the grinding rod 592 closer to the edge of the sealing groove. When the distance is appropriate, the fifth electric telescopic rod 52 stops extending. At this point, the third motor 54 starts, driving the second rotating block 56 to rotate via the third transmission shaft 55, adjusting the angle of the housing 57 so that the grinding rod 592 contacts the chamfered edge of the sealing groove. Subsequently, the fourth motor 59 starts, driving the T-shaped rotating sleeve 58 to rotate via the fourth drive shaft 591 and drive bar 595, thereby rotating the grinding rod 592 to grind the chamfered edge of the sealing groove. Simultaneously, the second rotating block 56 rotates, adjusting the angle of the housing 57 to grind the lower edge of the chamfer. During grinding, the fifth electric telescopic rod 52 extends and retracts appropriately according to the grinding progress, ensuring uniform contact pressure between the grinding rod 592 and the edge of the sealing groove, thus improving grinding quality. After grinding, the height of the grinding rod 592 is adjusted so that the spraying rod 593 rises to the previously ground position. Simultaneously, the pump body 598 starts. The epoxy coating coolant in the water tank 599 is transported to the connecting sleeve 5991 through the second connecting pipe 597 and the first connecting pipe 596. The liquid flows downward along the spiral groove 594 on the side wall of the spraying rod 593, and the spraying rod 593 rotates synchronously with the grinding rod 592. When the liquid reaches the end of the spiral groove 594, it is thrown out by centrifugal force and sprayed on the grinding area to cool, lubricate and reduce oxidation. After the cutting and grinding are completed, all mechanisms are reset, and multiple conveying wheels 15 start running again to transport the battery tray. The machine tool can then prepare for the processing of the next tray.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
