Description

Technical Field

[0001] The utility model relates to the technical field of electrophoretic coating, in particular to a clamp for electrophoretic coating of a battery bracket. Background Art

[0002] Electrophoretic coating is a coating process, also known as electrophoretic painting or electrophoretic coating. Electrophoretic coating is a coating method that uses an external electric field to make particles such as pigments and resins suspended in the electrophoretic liquid migrate in a directional manner and deposit on the substrate surface of one of the electrodes.

[0003] The battery bracket is composed of capacitor brackets distributed in a matrix and is used to install lithium battery assemblies. The clamp for electrophoretic coating of the battery bracket plays an important role in fixing the workpiece during the coating process. In the current existing technology, for the electrophoretic coating of the battery bracket, the rope suspended from the lifting line is mostly passed through the lithium battery holes of the battery bracket to complete the loading of the battery bracket. By lowering the lifting line, the battery bracket is immersed in the electrophoretic tank for coating.

[0004] The inventor discovered during the process of implementing the utility model:

[0005] When the above-mentioned existing method is used for painting, since the connection between the battery bracket and the lifting line relies on the lifting rope, the suspended battery bracket will often be tilted to one side. When the workpiece is tilted, the paint particles may not be evenly deposited on the workpiece surface under the action of the electric field, resulting in uneven coating and inconsistent paint thickness. In this regard, a battery bracket electrophoretic coating fixture is proposed to solve the above-mentioned problems. Summary of the invention

[0006] In order to solve the problems existing in the prior art, the utility model provides a battery bracket electrophoretic coating fixture, which has the advantages of adapting to different battery brackets to ensure that the workpiece enters the electrophoretic tank vertically during the coating process and avoids skewed immersion.

[0007] To this end, the technical solution of the utility model is: a battery bracket electrophoretic coating fixture, including a lifting plate and a fixture structure connected below the lifting plate, the fixture structure includes four clamping plates slidably connected to each other and a lock head arranged on the clamping plates,

[0008] A connecting groove connected to the slide groove is also provided on the top of the clamping plate, a connecting piece built into the connecting groove is provided on the clamping plate, and a lifting rope is connected between the connecting piece and the lifting plate.

[0009] Furthermore, the clamping plates are provided with sliding grooves on the left and right sides, and a connecting pipe is fixedly installed on one end of the clamping plate, and the connecting pipe extends to slide in the sliding groove of the adjacent clamping plate.

[0010] Furthermore, a threaded rod is threadedly installed in the connecting pipe, and the locking head is fixedly connected to the threaded rod.

[0011] Furthermore, the connecting member includes a slider slidably connected to the connecting groove, and a connecting ring is fixedly installed on the lower end of the slider. The connecting ring is sleeved on the outside of the threaded rod, and the inner diameter of the connecting ring is larger than the outer diameter of the threaded rod.

[0012] Furthermore, the connecting member also includes a connecting seat rotatably mounted on the top of the slider, the bottom end of the connecting seat is spherically embedded in the slider, and one end of the suspension rope is fixedly connected to the connecting seat.

[0013] Furthermore, a ball groove is provided on the outer wall of the lifting plate, and a ball located in the ball groove is rollingly installed on the outer side surface of the lifting plate, and the other end of the lifting rope is fixedly connected to the ball.

[0014] Furthermore, a docking seat is fixedly installed on the top of the lifting plate.

[0015] Beneficial effect: Compared with the prior art, the utility model sets four clamps to form a rectangular structure, and movably connects two adjacent clamps, so that the clamping surface can be flexibly adjusted to facilitate the clamping of different battery brackets. In addition, a suspension rope is set to move with the end of the clamp through the connecting seat, so that the suspension rope can change its position automatically to adapt to the adjusted position. At this time, the suspension rope constitutes a symmetrical structure, which can still maintain the horizontal state of the clamp after adjustment, so that the clamped battery bracket will not be immersed in the electrophoretic tank for painting in a skewed condition.

[0020] The technical solution of the present invention is clearly and completely described below in conjunction with the accompanying drawings, but this embodiment should not be understood as a limitation to the present invention.

[0021] The utility model Figures 1 to 3 As shown:

[0022] A clamp for electrophoretic coating of a battery bracket includes a lifting plate 1 and a clamp structure connected below the lifting plate 1. The clamp structure includes four clamps 2 slidably connected to each other and a lock 7 arranged on the clamps 2. The four clamps 2 can adjust the relative spacing to clamp different battery brackets.

[0023] Specifically, in this embodiment, a slide groove 3 is formed through the left and right sides of the clamping plate 2 , and a connecting pipe 5 is fixedly installed on one end of the clamping plate 2 , and the connecting pipe 5 extends into the slide groove 3 to slide.

[0024] In this design, the sliding stability between the two vertically fitted clamping plates 2 is improved and can be guided by the extension of the connecting pipe 5 .

[0025] In this embodiment, a threaded rod 6 is threadedly installed in the connecting pipe 5 , and a locking head 7 is fixedly connected to the threaded rod 6 .

[0026] Specifically, by pulling the lock head 7 to rotate, the threaded rod 6 can be moved relative to the connecting tube 5. At this time, the size of the lock head 7 is set to be larger than the width of the slide groove 3, so that the lock head 7 can abut against the outer surface of the clamping plate 2, thereby limiting the movement of the two clamping plates 2 that are perpendicular to each other.

[0027] It should be noted that the four clamps 2 are perpendicular to each other and connected along a rotation direction. The battery bracket is clamped by the inner sides of the four clamps 2. Since the four clamps 2 can move relative to each other, the clamping width and length can be flexibly adjusted, which is convenient for effective clamping of different products.

[0028] A connecting groove 4 connected to the slide groove 3 is also provided on the top of the splint 2 in this embodiment. A connecting piece built into the connecting groove 4 is provided on the splint 2. A lifting rope 11 is connected between the connecting piece and the lifting plate 1, so as to maintain the stable state of the splint 2.

[0029] In this embodiment, the connecting member includes a slider 9 slidably connected to the connecting groove 4, and a connecting ring 8 is fixedly installed on the lower end of the slider 9. The connecting ring 8 is sleeved on the outside of the threaded rod 6, and the inner diameter of the connecting ring 8 is larger than the outer diameter of the threaded rod 6.

[0030] Such a design ensures that the threaded rod 6 will not pull the connecting ring 8 when rotating, and the threaded rod 6 can drive the connecting ring 8 to change position when moving along the slide groove 3 .

[0031] It should be noted that the connecting member also includes a connecting seat 10 rotatably mounted on the top of the slider 9. The bottom end of the connecting seat 10 is spherically embedded in the slider 9. At this time, the connecting seat 10 can swing at different angles relative to the slider 9 to adapt to different adjustment positions. At the same time, one end of the suspension rope 11 is fixedly connected to the connecting seat 10.

[0032] A ball groove 12 is provided on the outer wall of the lifting plate 1 in this embodiment, and a ball 13 located in the ball groove 12 is rotatably mounted on the outer surface of the lifting plate 1;

[0033] Specifically, the other end of the suspension rope 11 is fixedly connected to the ball 13 , and the ball 13 rolls relative to the annular ball groove 12 , so that one end of the suspension rope 11 can flexibly change position along the outside of the suspension plate 1 .

[0034] In this embodiment, a docking seat 14 is fixedly mounted on the top of the hoisting plate 1. The docking seat 14 is a threaded seat or a clamping seat for connecting the coating hoisting line.

[0035] In this embodiment, four clamping plates 2 are arranged to form a rectangular structure, and two adjacent clamping plates 2 are movably connected, so that the clamping surface of the clamping plate 2 can be flexibly adjusted, which can facilitate the clamping of different battery brackets. In addition, a hanging rope 11 is arranged to move along with the end of the clamping plate 2 through the connecting seat 10, so that the hanging rope 11 can change its position automatically to adapt to the adjusted position. At this time, the hanging rope 11 constitutes a symmetrical structure, which can still maintain the horizontal state of the clamping plate 2 after adjustment, so that the clamped battery bracket will not be immersed in the electrophoretic tank for painting in a crooked condition.

[0036] The working principle of this utility model:

[0037] By rotating the four locks 7 at the ends of the four clamps 2, the clamps 2 can be loosened to change their positions. At the same time, the clamps 2 on both sides are slid to adjust the size of the rectangle surrounded by the four clamps 2 until they are clamped on the battery bracket and then the locks 7 are rotated to lock and clamp. During the adjustment, the threaded rod 6 connected to the end of the clamp 2 pulls the connecting ring 8, so that the slider 9 fixedly connected to the connecting ring 8 slides relative to the connecting groove 4, and the connecting seat 10 at the end of the slider 9 changes its position accordingly. When the four clamps 2 have adjusted their relative positions, the four connecting seats 10 are all at the four breakpoints of the rectangle surrounded by the clamps 2, and one end of the lifting rope 11 moves relative to the lifting plate 1 through the connecting ball 13, so that the clamp structure composed of the four clamps 2 can be stabilized. At this time, the lifting plate 1 is installed on the electrophoretic spray lifting line through the docking seat 14 to complete smooth painting.

[0038] Parts not described in detail in this specification are well-known technologies in the art.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
