Description

Technical Field

[0001] This utility model relates to the field of battery tray polishing technology, specifically to a new energy vehicle battery tray polishing device. Background Technology

[0002] The battery module is the core component of a new energy vehicle, and the battery tray, as the support for the entire battery module, has undergone innovative development in both materials and processes with technological advancements. Unlike traditional vehicles, new energy vehicles are powered by batteries, and the battery tray, containing individual battery cells, is fixed to the metal casing in a way that optimizes thermal management. It plays a crucial role in protecting the battery and ensuring its normal and safe operation, and its weight directly affects the overall load distribution and driving range of the electric vehicle. After processing, the battery tray requires polishing.

[0003] In the current process of grinding the bottom surface of a battery tray, to prevent the tray from moving, clamps are typically used to hold the tray in place on opposite sides before a grinding roller is used to grind the bottom surface. However, because the top edge of the battery tray has side plates around its perimeter, when the clamps press the tray down, these side plates are only subjected to a force in one direction. This can easily cause deformation of the opposite side plates, reducing product quality. Furthermore, during the grinding process, the surface of the grinding roller is prone to picking up grinding debris splashed from the battery tray, affecting the grinding effect. Utility Model Content

[0004] The purpose of this invention is to design a grinding device for battery trays of new energy vehicles, which can solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A grinding device for a new energy vehicle battery tray includes a support platform. A hydraulic cylinder is installed inside the support platform. The output end of the hydraulic cylinder passes through the top of the support platform and is fixedly connected to a grinding table. The top of the grinding table is provided with a first clamping plate and a second clamping plate for clamping side plates.

A power mechanism is provided above the housing for driving the housing in reciprocating motion. A blower communicating with the first inner cavity is provided on the power mechanism.

[0007] Furthermore, the driving mechanism includes a slide groove on the top of the grinding table and a first screw rotatably connected within the slide groove. The bottom of the first clamping plate is provided with a first slider that slides in cooperation with the slide groove, and the bottom of the second clamping plate is provided with a second slider that slides in cooperation with the slide groove. The first slider is provided with a forward-rotating threaded hole that is threadedly connected to the first screw, and the second slider is provided with a reverse-rotating threaded hole that is threadedly connected to the first screw.

[0008] Furthermore, the bottom of the first clamping plate is provided with two first limiting blocks symmetrically arranged with respect to the first slider, the bottom of the second clamping plate is provided with two second limiting blocks symmetrically arranged with respect to the second slider, and the top of the grinding table is provided with a first limiting groove and a second limiting groove corresponding to and slidingly engaging with the first limiting block (17) and the second limiting block, respectively.

[0009] Furthermore, both the first clamping plate and the second clamping plate are fixedly connected to anti-slip pads on the side that is close to each other.

[0010] Furthermore, the power mechanism includes a support frame, a second screw, and a servo motor. Two support frames are provided and fixed to opposite sides of the support platform. The two ends of the second screw are rotatably connected to the two support frames. The servo motor is fixed to one of the support frames, and its output end passes through the support frame and is fixedly connected to one end of the second screw. A support block is slidably connected between the two support frames. The bottom of the support block is fixedly connected to the top of the outer casing. The support block has a threaded hole that engages with the second screw. The blower is fixed to the top of the support block and communicates with the first inner cavity through a blower pipe.

[0011] Furthermore, two balancing slide rods symmetrically arranged with respect to the second screw are fixedly connected between the two support frames, and the support block is provided with sliding holes that slide in cooperation with the balancing slide rods.

[0012] Furthermore, a second inner cavity is provided in the side wall of the outer shell, and a dust suction port communicating with the second inner cavity is provided in the inner wall of the outer shell. A vacuum cleaner is fixed on the top of the support block, and the vacuum cleaner is connected to the second inner cavity through a dust suction pipe.

[0013] Furthermore, the length of both the air outlet and the dust suction outlet is the same as the length of the grinding roller.

[0014] The beneficial effects of this utility model are as follows:

[0015] The drive mechanism drives the first and second clamping plates to clamp one side plate of the battery tray, ensuring the force balance of the side plate, preventing deformation of the side plate of the battery tray, and improving product quality.

[0025] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0026] like Figure 1-5 As shown, a grinding device for a new energy vehicle battery tray includes a support platform 1. A hydraulic cylinder is installed inside the support platform 1, and the output end of the hydraulic cylinder passes through the top of the support platform 1 and is fixedly connected to a grinding platform 2. The height of the grinding platform 2 can be raised by the hydraulic cylinder to facilitate grinding the bottom surface of battery trays 33 of different thicknesses. The top of the grinding platform 2 is equipped with a first clamping plate 3 and a second clamping plate 4 for clamping the side plates 34 (side plates of the battery tray 33). The side of the grinding platform 2 is equipped with a drive mechanism that moves the first clamping plate 3 and the second clamping plate 4 towards or away from each other, thereby clamping or releasing the first clamping plate 3 and the second clamping plate 4. A housing 5 is located above the grinding platform 2, and a grinding roller 6 is rotatably connected inside the housing 5. A rotating... A rotary motor (not labeled in the diagram) has its output end inserted into the housing 5 and fixedly connected to one end of the grinding roller 6. The rotary motor drives the grinding roller 6 to rotate. The housing 5 has a first inner cavity 7 inside, and an air outlet 8 communicating with the first inner cavity 7 is provided in the side wall of the housing 5. The air outlet 8 is aligned with the grinding roller 6. A power mechanism for driving the housing 5 to reciprocate is provided on the top of the housing 5. A blower 9 communicating with the first inner cavity 7 is provided on the power mechanism. The power mechanism drives the housing 5 to move, which in turn drives the grinding roller 6 to move for grinding operations. During the grinding operation, the blower 9 discharges air into the first inner cavity 7, and then the air blows through the air outlet 8 to the grinding roller 6, separating the grinding debris adhering to the surface of the grinding roller 6.

[0027] The driving mechanism includes a slide groove 10 located on the top of the grinding table 2 and a first screw 11 rotatably connected within the slide groove 10. The bottom of the first clamping plate 3 has a first slider 12 that slides into the slide groove 10, and the bottom of the second clamping plate 4 has a second slider 13 that slides into the slide groove 10. The first slider 12 has a forward-rotating threaded hole 14 that is threaded to the first screw 11, and the second slider 13 has a reverse-rotating threaded hole 15 that is threaded to the first screw 11. When the first screw 11 rotates, due to the forward-rotating threaded hole 14 and the reverse-rotating threaded hole 15, the first slider 12 and the second slider 13 slide in opposite directions within the slide groove 10, thereby allowing the first clamping plate 3 and the second clamping plate 4 to move closer to or further away from each other. One end of the first screw 11 extends to the outside of the grinding table 2 and is fixedly connected. A handwheel 16 is provided, which can drive the first screw 11 to rotate. The bottom of the first clamping plate 3 is provided with two first limiting blocks 17 symmetrically arranged with respect to the first slider 12, and the bottom of the second clamping plate 4 is provided with two second limiting blocks 18 symmetrically arranged with respect to the second slider 13. The top of the grinding table 2 is provided with a first limiting groove 19 and a second limiting groove 20 corresponding to and slidingly engaging with the first limiting blocks 17 and the second limiting blocks 18. By limiting the first limiting blocks 17 with the first limiting groove 19 and limiting the second limiting blocks 18 with the second limiting groove 20, the stability of both ends of the first clamping plate 3 and the second clamping plate 4 during movement can be improved, thereby improving the clamping effect. Anti-slip pads are fixedly connected to the sides of the first clamping plate 3 and the second clamping plate 4 that are close to each other, which can increase the friction and further improve the clamping effect.

[0028] The power mechanism includes a support frame 21, a second screw 22, and a servo motor 23. Two support frames 21 are provided and fixed to opposite sides of the support platform 1. The two ends of the second screw 22 are rotatably connected to the two support frames 21. The servo motor 23 is fixed to one of the support frames 21, and its output end passes through the support frame 21 and is fixedly connected to one end of the second screw 22, driving the second screw 22 to rotate. A support block 24 is fixedly connected to the top of the outer casing 5, and the two support frames 21 are fixedly connected together. Two symmetrically arranged balance slide rods 27 are connected to the second screw 22. The support block 24 is provided with a threaded hole 25 that is threaded to the second screw 22, and a sliding hole 28 that is slidably engaged with the balance slide rods 27. When the second screw 22 rotates forward or backward, it can drive the support block 24 to reciprocate on the balance slide rods 27. The blower 9 is fixed on the top of the support block 24. The blower 9 is connected to the first inner cavity 7 through the blower pipe 26. The blower 9 discharges air into the first inner cavity 7 through the blower pipe 26.

[0029] The outer casing 5 has a second inner cavity 29 on its side wall. The inner wall of the outer casing 5 has a suction port 30 that communicates with the second inner cavity 29. A vacuum cleaner 31 is fixed on the top of the support block 24. The vacuum cleaner 31 is connected to the second inner cavity 29 through a suction pipe 32. After the vacuum cleaner 31 is started, the debris generated after the battery tray 33 is polished will be absorbed by the vacuum cleaner 31, ensuring the cleanliness of the battery tray 33 after polishing. The length of the blower 8 and the suction port 30 are the same as the length of the polishing roller 6, which can ensure that the polishing surface of the polishing roller 6 is cleaned and the bottom surface of the battery tray 33 is cleaned. There are two blowers 9 and two vacuum cleaners 31, which can improve the efficiency of cleaning the polishing roller 6 and the battery tray 33.

[0030] The new energy vehicle battery tray grinding device also includes a controller. The hydraulic cylinder, rotary motor, servo motor 23, blower 9 and vacuum cleaner 31 are all electrically connected to the controller. The controller controls the stopping or starting of the hydraulic cylinder, rotary motor, servo motor 23, blower 9 and vacuum cleaner 31, as well as the forward or reverse rotation of the servo motor 23 after it starts. Since the controller is existing technology, its working principle will not be described in detail.

[0031] Working principle:

[0032] like Figure 1-5 As shown, when using the grinding device, the battery tray 33 is placed on the grinding table 2, and the longer side plate 34 of the battery tray 33 is placed between the first clamping plate 3 and the second clamping plate 4. After the battery tray 33 is placed, the handwheel 16 is manually turned, which drives the first screw 11 to rotate, causing the first clamping plate 3 and the second clamping plate 4 to move closer to each other, thereby clamping the side plate 33, ensuring the force balance of the side plate 33, preventing the side plate 33 of the battery tray 33 from deforming, and improving product quality.

[0033] After the battery tray 33 is clamped, the height of the grinding table 2 can be adjusted up or down by the hydraulic cylinder to adjust the battery tray 33 to a suitable height. Then, the rotary motor, servo motor 23, blower 9 and vacuum cleaner 31 can be started. The servo motor 23 drives the second screw 22 to rotate forward, which drives the support block 24 to move from the suction port 30 to the blower port 8 on the balance slide bar 27. The rotary motor will drive the grinding roller to grind the bottom surface of the battery tray 33.

[0034] During the polishing process, the blower 9 blows air into the first inner cavity 7 through the blower pipe 26, and then blows the air through the blower nozzle 8 to the polishing roller 6 to separate the polishing debris on the surface of the polishing roller 6, so as to avoid reducing the polishing effect. The debris generated after the battery tray 33 is polished will be absorbed by the vacuum cleaner 31 to ensure the cleanliness of the battery tray 33 after polishing.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
