Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle processing technology, specifically to a surface treatment device for a protective cover for a new energy vehicle battery pack. Background Technology

[0002] The surface treatment of the protective cover for the battery pack of new energy vehicles is mainly divided into three steps: pretreatment, coating treatment and posttreatment. Among them, in the pretreatment stage, polishing is a common and important step, which aims to optimize the surface condition and provide a better adhesion base for subsequent coatings or other treatments.

[0003] A search revealed Chinese patent CN220561106U, which discloses an edge grinding device for a protective cover. The device includes a worktable and a grinding machine. Two sets of support legs are symmetrically installed at the bottom of the worktable, and telescopic cylinders are symmetrically installed at the top of the worktable. Moving plates are fixedly installed on the tops of the two telescopic cylinders. An L-shaped plate is fixedly installed on one side of the grinding machine. By setting up a fixing assembly, when fixing the battery protective cover, the cover is placed between two clamping plates. Rotating a third turntable drives a bidirectional threaded rod to rotate between the mounting blocks, thereby causing the two clamping plates to move closer together and fix the battery protective cover. The two clamping plates slide on a support slide rod during movement, improving the stability of the movement. This fixing assembly can fix battery protective covers of different sizes.

[0004] However, existing technologies use a rotating turntable to drive a bidirectional threaded rod to rotate during fixation, causing the two clamping plates to rotate in opposite directions. The clamping plates and the protective shell are in rigid contact. If the compressive force is not properly controlled, it can easily cause scratches, cracks, or even crushing of the protective shell, resulting in poor safety. In addition, although the fixation method is relatively simple, it requires manual rotation. When the size of the protective cover to be clamped is small, the number of rotations required is large, which increases the workload of the workers and reduces work efficiency.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this utility model is to provide a surface treatment device for a protective cover for a new energy vehicle battery pack that can effectively solve the above-mentioned technical problems.

[0007] To achieve the purpose of this utility model, the following technical solution is adopted:

[0008] A surface treatment device for a protective cover for a new energy vehicle battery pack includes: a processing table, an mounting plate fixedly installed on the top of the processing table, a grinding machine installed on the bottom of the mounting plate, two side plates symmetrically arranged on both sides of the upper surface of the processing table, an elastic mechanism provided on the opposite surfaces of the two side plates, a clamping plate connected to the side plates through the elastic mechanism, and a driving mechanism provided on the processing table relative to the positions of the two side plates.

[0009] Furthermore, the elastic mechanism includes a sleeve rod, an internal rod movably sleeved in the inner cavity of the sleeve rod, a linkage plate fixedly connected to one end of the internal rod, and a first spring sleeved in the inner cavity of the sleeve rod. The surface of the linkage plate is slidably connected to the inner wall of the sleeve rod, and the two ends of the first spring are fixedly connected to the bottom of the inner cavity of the sleeve rod and the side of the linkage plate, respectively.

[0010] Furthermore, the bottom end of the sleeve is fixedly connected to the side plate, and the end of the built-in rod away from the sleeve is connected to the clamping plate.

[0011] Furthermore, a snap-fit ​​groove is provided on the side of the clamping plate relative to the position of the built-in rod, and a fixing bolt is threadedly connected to the top of the clamping plate.

[0012] Furthermore, the driving mechanism includes a vertical plate fixedly installed on the top of the processing table, a slide groove formed on the side of the vertical plate, and a slider slidably connected to the inner cavity of the slide groove. The side of the slider is threaded with a bidirectional threaded rod, and the bidirectional threaded rod is rotatably connected to the vertical plate.

[0013] Furthermore, there are two sliders, which are symmetrically arranged at both ends of the bidirectional threaded rod, and are fixedly connected to the two side plates respectively.

[0014] Furthermore, it also includes a protective mechanism, which includes a controller fixedly installed on the side of the processing table, a servo motor fixedly installed on the side of the upright plate, the output end of the servo motor fixedly connected to one end of the bidirectional threaded rod, a pressure sensor provided in the inner cavity of the sleeve rod, a receiving plate fixedly installed at the bottom of the pressure sensor, a second spring fixedly connected to the bottom of the receiving plate, one end of the second spring fixedly connected to the bottom of the inner cavity of the sleeve rod, the second spring being disposed inside the first spring, the controller and the servo motor being electrically connected, and the pressure sensor and the controller being electrically connected.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The surface treatment device for the protective cover of the new energy vehicle battery pack, by setting an elastic mechanism, can change the rigid contact to an elastic contact by elastic contraction of the elastic mechanism when fixing the protective shell, thereby reducing the risk of damage to the protective shell.

[0016] 2. The surface treatment device for the protective cover of the new energy vehicle battery pack, by setting a protective mechanism, can drive the bidirectional threaded rod to rotate during fixing, and then fix the protective cover through two clamps. By setting a pressure sensor, pressure can be applied to the pressure sensor when the elastic mechanism elastically contracts. When the pressure reaches the set value, the servo motor can be stopped under the action of the controller, thereby reducing the risk of damage to the protective cover, shortening the fixing time of the protective cover, and improving work efficiency.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below.

[0026] like Figures 1 to 5 As shown, this utility model relates to a surface treatment device for a protective cover for a new energy vehicle battery pack, comprising: a surface treatment device for a protective cover for a new energy vehicle battery pack, including a processing table 1, a mounting plate 2 fixedly installed on the top of the processing table 1, a grinding machine 3 installed on the bottom of the mounting plate 2, two side plates 4 symmetrically arranged on both sides of the upper surface of the processing table 1, and elastic mechanisms 5 provided on the opposite surfaces of the two side plates 4, with clamping plates 6 connected to the side plates 4 through the elastic mechanisms 5, and a driving mechanism 7 provided on the processing table 1 at a position relative to the two side plates 4; when When polishing the protective cover, the protective cover is placed on the processing table 1 and located inside the two clamping plates 6. Then, the driving mechanism 7 is moved by the protective mechanism 8. With the connection of the side plate 4, the elastic mechanism 5 and the two clamping plates 6 can move towards each other, thereby clamping the protective cover. Then, it can be polished by the polishing machine 3. The specific polishing operation is existing technology, so it is not described in detail in this technical solution. For details, please refer to the edge polishing device for a protective cover disclosed in the authorization announcement number CN220561106U.

[0027] It should also be noted that during the clamping process of the protective cover, by setting the elastic mechanism 5, the rigid contact can be changed to elastic contact when the protective shell is fixed, thereby reducing the risk of damage to the protective shell. By setting the protective mechanism 8, the risk of damage to the protective shell can be reduced, while shortening the fixing time of the protective shell and improving work efficiency.

[0028] The elastic mechanism 5 includes a sleeve rod 51, an inner rod 52 movably sleeved in the inner cavity of the sleeve rod 51, a linkage plate 53 fixedly connected to one end of the inner rod 52, and a first spring 54 sleeved in the inner cavity of the sleeve rod 51. The surface of the linkage plate 53 is slidably connected to the inner wall of the sleeve rod 51. The two ends of the first spring 54 are fixedly connected to the bottom of the inner cavity of the sleeve rod 51 and the side of the linkage plate 53, respectively. The bottom end of the sleeve rod 51 is fixedly connected to the side plate 4. The end of the inner rod 52 away from the sleeve rod 51 is connected to the clamping plate 6. When the clamping plate 6 contacts and compresses the protective shell, the inner rod 52 connected to the clamping plate 6 retracts into the sleeve rod 51. Under the connection of the linkage plate 53, the first spring 54 can be compressed, thereby changing the rigid contact to an elastic contact, thus reducing the risk of damage to the protective shell.

[0029] The clamping plate 6 has a snap-fit ​​groove 61 on its side relative to the built-in rod 52, and a fixing bolt 62 is threaded to the top of the clamping plate 6. When fixing protective shells of different shapes, the fixing bolt 62 can be removed to disassemble the clamping plate 6. When installing a suitable clamping plate 6, the snap-fit ​​groove 61 on the side of the clamping plate 6 is inserted into the surface of the built-in rod 52, and then the installation of the new clamping plate 6 can be completed by fixing the bolt 62.

[0030] Furthermore, the drive mechanism 7 includes a vertical plate 71 fixedly installed on the top of the processing table 1, a slide groove 72 opened on the side of the vertical plate 71, and a slider 73 slidably connected to the inner cavity of the slide groove 72. The side of the slider 73 is threadedly connected to a bidirectional threaded rod 74, and the bidirectional threaded rod 74 is rotatably connected to the vertical plate 71. There are two sliders 73, which are symmetrically arranged at both ends of the bidirectional threaded rod 74. The two sliders 73 are fixedly connected to the two side plates 4 respectively. When driving the clamping plate 6, by rotating the bidirectional threaded rod 74, the two sliders 73 threadedly connected to the bidirectional threaded rod 74 can move towards each other. With the connection of the side plate 4 and the elastic mechanism 5, the two clamping plates 6 can move towards each other, thereby completing the fixation of the protective cover.

[0031] Furthermore, it also includes a protective mechanism 8, which includes a controller 81 fixedly installed on the side of the processing table 1, a servo motor 82 fixedly installed on the side of the upright plate 71, the output end of the servo motor 82 being fixedly connected to one end of the bidirectional threaded rod 74, a pressure sensor 83 being provided in the inner cavity of the sleeve rod 51, a receiving plate 831 being fixedly installed at the bottom of the pressure sensor 83, a second spring 832 being fixedly connected at the bottom of the receiving plate 831, one end of the second spring 832 being fixedly connected to the bottom of the inner cavity of the sleeve rod 51, the second spring 832 being located inside the first spring 54, the controller 81 and the servo motor 82 being electrically connected, and the pressure sensor 83 and the controller 81 being electrically connected.

[0032] Specifically, during the fixing process, the servo motor 82 drives the bidirectional threaded rod 74 to rotate, which in turn fixes the protective cover through the two clamping plates 6. Compared with manual rotation, the use of the servo motor 82 in this technical solution can improve the rotation efficiency of the bidirectional threaded rod 74, thereby shortening the fixing time of the protective cover and improving work efficiency. By setting a pressure sensor 83, the pressure sensor 83 can be squeezed during the process of the built-in rod 52 and the linkage plate 53 retracting into the sleeve rod 51. When the pressure reaches the set value, the servo motor 82 can be stopped under the action of the controller 81, thereby reducing the risk of damage to the protective cover. At the same time, the pressure sensor 83 can be installed by setting a receiving plate 831, and the pressure sensor 83 can be kept in a position close to the linkage plate 53 by setting a second spring 832. Thus, pressure can be applied to the pressure sensor 83 when the linkage plate 53 retracts, thereby synchronously detecting the pressure value and sending a signal to the controller 81 in time to stop the servo motor 82, avoiding damage to the protective cover due to excessive squeezing force.

[0033] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.
