Description

Technical Field

[0001] This utility model relates to the field of automotive bracket positioning, and in particular to a batch electrophoresis positioning bracket. Background Technology

[0002] In the automotive industry, mass production electrophoresis brackets are used in the electrophoretic coating process, which is a process of electrodepositing paint onto a metal surface to protect vehicles from corrosion and other environmental factors. When performing mass electrophoretic coating, positioning brackets are required to ensure stability during the process.

[0003] The existing patent (publication number: CN218404462U) discloses "This application relates to a positioning bracket for mass electrophoresis of automotive parts, including a frame and a workpiece. The frame consists of a base plate, side plates, and a back plate. The side plates are fixedly installed on the top of the base plate, and multiple sets of side plates are provided. One end of the side plate is fixed to one side of the back plate, and the back plate is installed on the top of the base plate. A positioning mechanism is fixedly installed on one side of the side plate. The positioning mechanism includes a telescopic cylinder, and a spring is installed in the inner cavity of the telescopic cylinder. A support rod is movably inserted into one end of the inner cavity of the telescopic cylinder, and the support rod is located at one end of the spring. A roller is rolled on the end of the support rod away from the spring. By setting the positioning mechanism, the positioning mechanism can clamp workpieces of different thicknesses, improving applicability. Moreover, the clamping operation is simple and convenient, without the need for manual adjustment of the positioning mechanism. The limiting plate supports one end of the workpiece, reducing the possibility of the workpiece shaking due to the rolling of the roller."

[0004] In the process of developing this utility model, the inventors discovered the following problems with the existing technology: the device uses pulleys with relatively fixed positions for clamping, which is only suitable for car brackets with a certain profile. Since car brackets often have a certain curvature, it is impossible to ensure that multiple pulleys can act on both sides of the car bracket. When the car bracket is small, it cannot be effectively clamped. At the same time, when the entire device is placed in the electrophoresis solution, the resistance of the electrophoresis solution may cause the car bracket to move, resulting in poor stability.

[0005] Therefore, those skilled in the art have provided a batch electrophoresis positioning scaffold to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a batch electrophoresis positioning bracket. This device can adjust the position of each pulley according to the size of the car bracket. It is simple to operate and more flexible. All pulleys can rotate 90°. After rotation, the rotation directions of the pulleys on both sides conflict, which makes the clamping of the car bracket more stable and less prone to slippage.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a batch electrophoresis positioning bracket, comprising a shell, a positioning mechanism disposed inside the shell, multiple hanging rings fixedly disposed on both sides of the upper end of the shell, the positioning mechanism comprising multiple side plates and multiple fixing plates, a double-threaded screw rod rotatably disposed through the interior of each of the multiple fixing plates, a turntable fixedly disposed at the upper end of each of the multiple double-threaded screw rods, sleeve plates threadedly fitted around the upper and lower parts of each of the multiple double-threaded screw rods, a horizontal plate fixedly disposed at the rear end of each of the multiple sleeve plates, a moving block slidably disposed in the groove inside each of the multiple horizontal plates, multiple inclined plates fixedly disposed on the inner side of each of the multiple side plates, a telescopic rod rotatably disposed on the inner side of each of the multiple moving blocks, a pulley rotatably disposed on the inner side of the telescopic part of each of the multiple telescopic rods, and a No. 1 spring disposed inside each of the multiple telescopic rods;

[0008] Each of the multiple telescopic rods has two protrusions fixedly installed around its internal portion within the moving block. Each of the multiple moving blocks has a limit block that slides through it near the top of the corresponding telescopic rod. A second spring is installed between the upper end of each of the multiple limit blocks and the interior of the moving block.

[0009] Furthermore, each of the multiple movable blocks includes a cylindrical block and a square block, with the multiple cylindrical blocks being snapped and slidably disposed within the corresponding grooves of the horizontal plate, and the multiple square blocks being snapped and slidably disposed within the grooves of the inclined plate.

[0010] Furthermore, each of the multiple side plates has four inclined plates on its side surface, and the inclined plates on the same side surface are all inclined at 45°.

[0011] Furthermore, the multiple horizontal plates are slidably disposed inside the corresponding side plates, and the dimensions of the multiple moving blocks located inside the inclined plates are consistent with the dimensions of the grooves inside the inclined plates.

[0012] Furthermore, the fixed parts of the multiple telescopic rods are located inside the movable block and are fixedly provided with multiple teeth, and the limiting block is located between two adjacent teeth when it is not being squeezed.

[0013] Furthermore, each of the multiple movable blocks has a top block fixedly installed at the bottom upper end near the center of the telescopic rod, and the multiple protrusions will contact the top block during the rotation of the telescopic rod.

[0014] Furthermore, when the telescopic rod is not rotating, the pulleys rotate in a vertical direction, and the included angle between any two adjacent protrusions is 90°.

[0015] Furthermore, each of the multiple double-threaded screws is provided with upper and lower threads on its upper and lower sides, respectively. The direction of the multiple upper threads is opposite to that of the lower threads. Among the multiple sleeves, the upper sleeves are threaded onto the upper threads, and the lower sleeves are threaded onto the lower threads.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model proposes a batch electrophoresis positioning bracket. When fixing the bracket, the car bracket can be inserted between two side plates. Due to the thickness of the car bracket, the pulley can rotate and squeeze the No. 1 spring inside the telescopic rod. The elasticity of the No. 1 spring is used for clamping. According to the size and contour of the car bracket, the turntable can be rotated to rotate the double threaded screw. At this time, the upper and lower sleeve plates will move towards each other with the corresponding horizontal plates. Multiple pulleys that are locked and slidably set inside the horizontal and inclined plates will move obliquely towards the center point of the side plate. At this time, it can be well adapted to different car brackets by adjustment, which is more flexible and can be used to fix car brackets of different sizes and contours. It can be achieved by simply rotating one rod, and the operation is simple.

[0018] 2. The present invention proposes a batch electrophoresis positioning bracket. After clamping the car bracket, the device can rotate the telescopic rod located on one side of the car bracket while keeping the telescopic rod on the other side unchanged. When manually rotated, the rotation of the part of the telescopic rod located inside the moving block will press the limiting block in. It can rotate up to 90°. At this time, the rotation direction of the pulleys on both sides of the car bracket conflicts, and the car bracket will not be able to move up, down, left, and right well. This makes the clamping more stable and will not be affected by the electrophoresis liquid and will not move. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figure 1 One embodiment of this utility model is a batch electrophoresis positioning bracket, which includes a shell 2, a positioning mechanism 1 is provided inside the shell 2, and multiple hanging rings 3 are fixedly provided on both sides of the upper end of the shell 2.

[0029] Specifically, the overall structure is suspended into the electrophoretic coating pool by the lifting ring 3 for electrophoretic coating. The positioning mechanism 1 can be adjusted according to size changes and can also provide more stable clamping, thus enabling better electrophoretic coating work.

[0030] Reference Figures 2 to 6 The positioning mechanism 1 includes multiple side plates 101 and multiple fixed plates 102. Each fixed plate 102 has a double threaded screw 103 rotatably mounted inside. Each double threaded screw 103 has a turntable 104 fixedly mounted at its upper end. Each double threaded screw 103 has a sleeve plate 105 threadedly mounted on its upper and lower sides. Each sleeve plate 105 has a horizontal plate 106 fixedly mounted at its rear end. Each horizontal plate 106 has a moving block 107 slidably mounted in its internal groove. Each side plate 101 has multiple inclined plates 108 fixedly mounted inside. Each moving block 107 has a telescopic rod 109 rotatably mounted inside. Each telescopic rod 109 has a pulley 110 rotatably mounted inside its telescopic part. Each telescopic rod 109 has a first spring 111 inside.

[0031] Each of the multiple telescopic rods 109 located inside the moving block 107 has two protrusions 114 fixedly installed around its perimeter. Each of the multiple moving blocks 107 has a limit block 112 slidingly installed inside the moving block 107 near the top of the corresponding telescopic rod 109. Each of the multiple limit blocks 112 has a second spring 113 installed between its upper end and the inside of the moving block 107.

[0032] Each of the multiple movable blocks 107 includes cylindrical blocks and square blocks. The multiple cylindrical blocks are snapped and slidably disposed in the internal grooves of the corresponding horizontal plates 106. The multiple square blocks are snapped and slidably disposed in the internal grooves of the inclined plates 108. Each of the multiple side plates 101 has four inclined plates 108 on its side. The inclined plates 108 on the same side are all inclined at 45°. The multiple horizontal plates 106 are slidably disposed inside the corresponding side plates 101. The circumferential dimensions of the multiple movable blocks 107 located inside the inclined plates 108 are consistent with the dimensions of the internal grooves of the inclined plates 108. The fixed parts of the multiple telescopic rods 109 are fixedly provided with multiple teeth on the circumference of the internal parts of the movable blocks 107. When the limiting block 112 is not squeezed, it is located between two adjacent teeth.

[0033] Multiple movable blocks 107 are fixedly provided with top blocks at the bottom upper end near the center of the telescopic rod 109. Multiple protrusions 114 will contact the top blocks during the rotation of the telescopic rod 109. Multiple pulleys 110 rotate vertically when the telescopic rod 109 is not rotating. The included angle between any two adjacent protrusions 114 is 90°. Multiple double-threaded screws 103 are provided with upper and lower threads respectively at the top and bottom of their circumference. The direction of the upper threads is opposite to that of the lower threads. Multiple sleeves 105 are threaded around the upper threads of the upper sleeves 105, and multiple sleeves 105 are threaded around the lower threads of the lower sleeves 105.

[0034] Specifically, when the double-threaded screw 103 rotates, the upper sleeves 105 will move downwards under the action of the upper thread, while the lower sleeves 105 will move upwards under the action of the lower thread. The multiple limit blocks 112 cooperate with the second spring 113. Each limit block 112 will restrict the rotation of the corresponding telescopic rod 109 to ensure that it will not rotate spontaneously without manual operation. In actual operation, it is necessary to ensure that only one side of the telescopic rod 109 on both sides of a car bracket is rotated. Only a portion of the teeth around the multiple telescopic rods 109 are designed, and they only contact and squeeze the limit blocks 112 with slopes within a 90° range.

[0035] Working principle: When the device clamps the car bracket, if the pulleys 110 between two adjacent side plates 101 cannot be positioned well on both sides of the bracket to be placed, the turntable 104 can be rotated to rotate the double threaded screw 103. At this time, the two sleeve plates 105 located above and below will move towards each other, and the horizontal plates 106 on both sides of the sleeve plates 105 will also slide synchronously inside the side plates 101. Under the dual constraint of the horizontal groove inside the side plate 101 and the inclined groove inside the inclined plate 108, the moving block 107 can move obliquely. The four moving blocks 107 located on the same side of the side plate 101 will move towards the center of the side plate 101 with the telescopic rod 109 and the pulleys 110, which can better adapt to the planar area position of the car bracket for clamping.

[0036] Secondly, after the initial clamping is completed, the multiple telescopic rods 109 on one side of the car bracket can be rotated. Under the restriction of the protrusion 114 and the top block inside the moving block 107, they can rotate 90°. Since the fixed part of the telescopic rod 109 is equipped with teeth, the teeth can squeeze the limiting block 112 into the moving block 107 when rotating. Then, the rotation of the telescopic rod 109 is restricted by the reset action of the second spring 113, which can ensure that the telescopic rod 109 will not rotate spontaneously. The rotation directions of the pulleys 110 on both sides of the bracket conflict, and the bracket clamping is more stable at this time.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
