Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and in particular to a flexible grinding device for the surface of a heat sink plate for new energy vehicle batteries. Background Technology

[0002] New energy vehicles refer to automobiles that use unconventional vehicle fuels as their power source (or use conventional vehicle fuels but employ new onboard power devices), integrating advanced technologies in vehicle power control and drive, resulting in vehicles with advanced technical principles and new technologies and structures. New energy vehicles include pure electric vehicles, range-extended electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, and hydrogen engine vehicles.

[0003] In the existing technology, during the production process of new energy vehicle battery heat sinks, the surface of the battery heat sink needs to be polished. During polishing, clamping tools are used to hold and fix the battery heat sink, which means that the clamping part of the battery heat sink cannot be polished properly. The clamping position needs to be changed and the unpolished area needs to be polished again. Since the clamping tool is operated manually, it is time-consuming and labor-intensive, resulting in low efficiency of battery heat sink polishing. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology that, during the production of new energy vehicle battery heat sinks, the surface of the battery heat sink needs to be polished. During polishing, clamping tools are used to hold and fix the battery heat sink, which makes it impossible to polish the clamping parts of the battery heat sink properly. The clamping position needs to be changed and the unpolished areas need to be polished again. Since the clamping tools are operated manually, it is time-consuming and labor-intensive, resulting in low efficiency in polishing battery heat sinks.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a flexible grinding device for the surface of a heat sink plate of a new energy vehicle battery, comprising: a worktable, and further comprising:

[0006] Multiple rotating rods are symmetrically connected to the top of the workbench in pairs. One end of each rotating rod is fixedly connected to a W-shaped connecting plate. Two cylinders are symmetrically fixedly connected to the top of the W-shaped connecting plate. One end of each cylinder is fixedly connected to a pressure plate. The other end of each rotating rod is fixedly connected to a gear. Multiple racks are symmetrically arranged in pairs at the bottom of the workbench. The racks are meshed with the gears.

[0007] Preferably, the bottom of the worktable is symmetrically and fixedly connected with multiple guide rails in pairs, and the guide rails are slidably connected with convex strips, which are fixedly connected to racks.

[0008] Preferably, a fixing block two is fixedly connected to the bottom of the workbench, a cylinder two is fixedly connected to one side of the fixing block two, an I-shaped plate is fixedly connected to one end of the cylinder two, and the I-shaped plate is fixedly connected to the rack.

[0009] Preferably, two fixed blocks are symmetrically fixedly connected to opposite sides of the worktable. A lead screw is rotatably connected to the opposite side of the two fixed blocks, and a guide rod is fixedly connected to the opposite side of the other two fixed blocks. A U-shaped frame is threadedly connected to the outer surface of the lead screw, and the U-shaped frame is slidably connected to the guide rod. A servo motor is fixedly connected to one side of one of the fixed blocks, and the output end of the servo motor is fixedly connected to one end of the lead screw.

[0010] Preferably, a lead screw two is rotatably connected to one side of the two arms of the U-shaped frame, a servo motor two is fixedly connected to the side of the U-shaped frame near the top, the output end of the servo motor two is fixedly connected to one end of the lead screw two, a slider is threaded to the outer surface of the lead screw two, a cylinder three is fixedly connected to the bottom of the slider, and a grinder is fixedly connected to one end of the cylinder three.

[0012] Preferably, the top of the workbench is provided with a placement area, and the bottom of the pressure plate is fixedly connected with an elastic rubber pad.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. This utility model uses a controller to activate cylinder two, causing it to extend and push the I-shaped plate to one side. Simultaneously, this moves the rack to one side, allowing the convex strip to slide inside the guide rail. Then, with the meshing of the rack and gear, the gear drives the rotating rod to rotate at an appropriate angle, simultaneously rotating the W-shaped connecting plate. This causes multiple cylinders to move away from above the battery heat sink, while other cylinders move to above it. The controller then extends these other cylinders, causing the pressure plate and elastic rubber pad to press firmly against the battery heat sink. This facilitates the re-grinding of areas on the battery heat sink that were not properly ground, saving time and effort and improving the efficiency of battery heat sink grinding.

[0015] 2. In this utility model, with the cooperation of the I-shaped plate, when the controller controls the cylinder two to extend or retract, multiple racks can be driven simultaneously. With the cooperation of the racks and gears, multiple rotating rods can be rotated simultaneously, and the angles of multiple W-shaped connecting plates can be adjusted at the same time, thereby improving the ease of use of this device.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Examples, such as Figure 1-4As shown, this utility model provides a flexible grinding device for the surface of a heat sink plate of a new energy vehicle battery, including: a workbench 1, and multiple rotating rods 4, which are symmetrically and rotatably connected to the top of the workbench 1 in pairs. One end of the rotating rod 4 is fixedly connected to a W-shaped connecting plate 401, and two cylinders 402 are symmetrically and fixedly connected to the top of the W-shaped connecting plate 401. One end of the cylinder 402 is fixedly connected to a pressure plate 403, and the other end of the rotating rod 4 is fixedly connected to a gear 506. Multiple racks 503 are symmetrically arranged in pairs at the bottom of the workbench 1, and the racks 503 are meshed with the gears 506.

[0025] Furthermore, such as Figure 1-4 As shown, multiple guide rails 505 are symmetrically fixedly connected to the bottom of the worktable 1. A convex strip 504 is slidably connected inside the guide rail 505. The convex strip 504 is fixedly connected to the rack 503. By causing the rack 503 to drive the convex strip 504 to slide along the inside of the guide rail 505, the rack 503 can be supported to a certain extent.

[0026] Furthermore, such as Figure 1-4 As shown, a fixing block 2 5 is fixedly connected to the bottom of the workbench 1. A cylinder 2 501 is fixedly connected to one side of the fixing block 2 5. An I-shaped plate 502 is fixedly connected to one end of the cylinder 2 501. The I-shaped plate 502 is fixedly connected to the rack 503. The cylinder 2 501 is started by the controller to extend and push the I-shaped plate 502 to one side, which in turn drives the rack 503 to move to one side.

[0027] Furthermore, such as Figure 1-4 As shown, two fixed blocks 2 are symmetrically fixedly connected to opposite sides of the worktable 1. A lead screw 201 is rotatably connected to the opposite side of the two fixed blocks 2, and a guide rod 203 is fixedly connected to the opposite side of the other two fixed blocks 2. A U-shaped frame 3 is threadedly connected to the outer surface of the lead screw 201. The U-shaped frame 3 is slidably connected to the guide rod 203. A servo motor 202 is fixedly connected to one side of one of the fixed blocks 2. The output end of the servo motor 202 is fixedly connected to one end of the lead screw 201. The controller controls the servo motor 202 to start, so that its output shaft drives the lead screw 201 to rotate. Then, with the cooperation of the threaded connection between the lead screw 201 and the U-shaped frame 3, and with the cooperation of the guide rod 203 to limit and guide the U-shaped frame 3, the U-shaped frame 3 can move left and right along the outer surface of the lead screw 201.

[0028] Furthermore, such as Figure 1-4As shown, a lead screw 301 is rotatably connected to one side of the two arms of the U-shaped frame 3. A servo motor 302 is fixedly connected to the side of the U-shaped frame 3 near the top. The output end of the servo motor 302 is fixedly connected to one end of the lead screw 301. A slider 304 is threadedly connected to the outer surface of the lead screw 301. A cylinder 3 is fixedly connected to the bottom of the slider 304. A grinder 305 is fixedly connected to one end of the cylinder 3. The controller controls the servo motor 202 to start, so that its output shaft drives the lead screw 301 to rotate. Then, under the action of the threaded engagement between the lead screw 301 and the slider 304, the slider 304 can move back and forth along the outer surface of the lead screw 301, thereby controlling the grinder 305 to move back and forth. Simultaneously, the controller controls the cylinder 3 to control the grinder 305 to move up and down. The controller also controls the grinder 305 to start, so that it can grind the battery heat sink.

[0029] Furthermore, such as Figure 1-4 As shown, the top of the U-shaped frame 3 is provided with a slide groove 303, and the outer surface of the slider 304 is slidably connected to the inside of the slide groove 303. By setting the slide groove 303, the slider 304 can be limited so that the slider 304 can only slide along the inside of the slide groove 303.

[0030] Furthermore, such as Figure 1-4 As shown, the top of the workbench 1 is provided with a placement area 101, and the bottom of the pressure plate 403 is fixedly connected with an elastic rubber pad. The placement area 101 facilitates the placement of the battery heat sink, and the elastic rubber pad can prevent damage to the battery heat sink.

[0031] Working principle: In use, the heat sink of the new energy vehicle battery is placed in the placement area 101. The controller then activates multiple cylinders 402 to extend them, causing the pressure plate 403 to move downwards. With the help of the elastic rubber pad, the heat sink is pressed firmly. At this time, depending on the area to be polished, the controller activates the servo motor 202, causing its output shaft to drive the lead screw 201 to rotate. Then, with the threaded connection between the lead screw 201 and the U-shaped frame 3, and with the guide rod 203 providing limiting guidance to the U-shaped frame 3, the U-shaped frame 3 can be... The frame 3 moves left and right along the outer surface of the lead screw 201, thereby controlling the left and right movement of the grinder 305. Simultaneously, the controller starts the servo motor 202, causing its output shaft to drive the lead screw 301 to rotate. Then, under the action of the threaded engagement between the lead screw 301 and the slider 304, and with the limiting and guiding action of the slide groove 303 on the slider 304, the slider 304 can move back and forth along the outer surface of the lead screw 301, thereby controlling the back and forth movement of the grinder 305. Simultaneously, the controller controls the cylinder 3, which in turn controls the up and down movement of the grinder 305. The controller activates the grinder 305 to grind the battery heat sink. When most of the grinding is complete, the pressing area of ​​the pressure plate 403 needs further grinding. The controller then controls multiple cylinders 402 to retract, causing the pressure plate 403 to move upwards and release the pressure on the battery heat sink. Next, the controller activates cylinder 501 to extend, pushing the I-beam plate 502 to one side, simultaneously moving the rack 503 to one side. This causes the convex strip 504 to slide inside the guide rail 505. Then, the rack 503 and the gear... With the meshing of gears 506, the rotating rod 4 can be rotated at an appropriate angle, which in turn drives the W-shaped connecting plate 401 to rotate. This causes multiple cylinders 402 to move away from above the battery heat sink, while other cylinders 402 move to above the battery heat sink. The controller then controls the extension of these other cylinders 402, which in turn causes the pressure plate 403 and the elastic rubber pad to press the battery heat sink firmly. This allows the grinder 305 to re-grind areas of the battery heat sink that have not been properly ground. This process is more time-saving and labor-saving, thereby improving the efficiency of grinding the battery heat sink.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
