Description
Technical Field
[0001] This utility model relates to the field of charging pile processing technology, specifically to a modular clamping fixture for machining split charging piles. Background Technology
[0002] A fixture is a device used in mechanical manufacturing to fix a workpiece in the correct position for construction or inspection. With the increasing emphasis on green and environmentally friendly practices in today's society, electric vehicles have become a popular choice for purchase and use, and their proportion is constantly increasing. Consequently, charging piles for electric vehicles have become essential everyday equipment, leading to a greater demand for more practical charging pile processing equipment and corresponding fixtures in modern manufacturing plants.
[0003] For example, Chinese patent (CN222696570U) discloses a modular clamping fixture for machining split charging piles. It includes a housing with a panel. Support columns are located on both sides of the panel, and each support column has a vertical moving slot on one side of the panel. A first connecting arm and a second connecting arm are respectively engaged in the two vertical moving slots. A lifting platform is located inside the housing. One end of each of the first and second connecting arms is welded to the lifting platform. The lifting platform has two threaded holes with threads on their inner walls. A threaded rod is threaded into each threaded hole, and one end of the threaded rod has a threaded rod fixing platform. The threaded rod and the threaded rod fixing platform are rotatably connected. By using the output of a second motor, the up-and-down movement of the connecting arms can be controlled. This not only controls the up-and-down position of the connecting arms but also allows for the up-and-down movement of the workpiece while clamping it to meet different machining needs, making it convenient to use.
[0004] The aforementioned device can only clamp the split charging pile on the left and right sides, which may not provide sufficient stability. Especially during processing that requires withstanding large external forces or vibrations, the lack of support points in other directions will cause the workpiece to shake, affecting processing accuracy and quality. To address the above problems, a split charging pile machining combination fixture is proposed to solve the problem. Utility Model Content

[0022] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0023] Reference Figures 1-5As shown, a modular clamping fixture for machining split charging piles includes a mounting plate 1. Slots 10 are provided on both the left and right sides of the upper surface of the mounting plate 1. These slots 10 provide space for the connecting columns 1203 in the clamping assembly 12, allowing the support plate 1204 to move with the moving plate 1202, thus enabling clamping of workpieces of different sizes and enhancing the fixture's versatility. Two connecting seats 2 are fixedly connected to the rear side of the slots 10 on the upper surface of the mounting plate 1. A baffle 3 is fixedly connected to the front side of the two connecting seats 2, serving as a rear positioning reference. When placing a workpiece, the rear side of the workpiece approximately abuts against the baffle 3 to achieve rapid positioning, improving workpiece installation efficiency and ensuring the workpiece's positional stability during machining, reducing machining errors caused by positional deviations. The clamping assembly 12 is fixedly installed at the bottom of the mounting plate 1. A first cylinder 4 is fixedly connected to the middle of the front side of the upper surface of the mounting plate 1. A connecting plate 5 is fixedly connected to the output end of the first cylinder 4. A pressing plate 6 is fixedly connected to the rear side of the connecting plate 5 by bolts. Rubber pads 7 are fixedly connected to the four corners of the rear side of the pressing plate 6.
[0024] Furthermore, guide blocks 8 are fixedly connected to both sides of the first cylinder 4 on the upper surface of the mounting plate 1. Guide rods 9 are slidably connected inside the two guide blocks 8. The rear sides of the two guide rods 9 are fixedly connected to the front side of the connecting plate 5. Pads 11 are fixedly connected to the four corners of the bottom surface of the mounting plate 1. The pads 11 separate the mounting plate 1 from the worktable of the processing equipment by a certain distance. On the one hand, this can prevent the mounting plate 1 from directly contacting the worktable and causing wear. On the other hand, it provides sufficient installation and movement space for components such as the clamping assembly 12. It also facilitates the overall installation and adjustment of the fixture.
[0025] Furthermore, the clamping assembly 12 includes two movable guide rails 1201. The two movable guide rails 1201 are fixedly connected to the bottom surface of the mounting plate 1 and located on the front and rear sides of the slot 10. The left and right sides of the bottom surface of the two movable guide rails 1201 are slidably connected to movable plates 1202 through sliding blocks. The movable plates 1202 are the main moving parts of the clamping assembly 12. They are connected to the movable guide rails 1201 through sliding blocks and can move flexibly along the movable guide rails 1201 to clamp workpieces of different sizes.
[0026] Furthermore, connecting columns 1203 are fixedly connected to the upper center of both movable plates 1202. The upper ends of the two connecting columns 1203 pass through two sets of slots 10 and are fixedly connected to support plates 1204. Two sets of rotating seats 1205 are fixedly connected to the inner side of the two support plates 1204. Guide rollers 1206 are rotatably connected between the four sets of rotating seats 1205. The guide rollers 1206 can rotate on the rotating seats 1205. When the extrusion plate 6 extrudes the workpiece, if the workpiece is positioned too far forward, i.e. there is a gap between the workpiece and the baffle 3, the rotation of the guide rollers 1206 can move the workpiece backward within a certain range to achieve gap compensation, ensure that the rear side of the workpiece is in close contact with the baffle 3, and improve the clamping accuracy and stability.
[0027] Furthermore, the clamping assembly 12 includes a rotating shaft 1207, which is fixedly connected to the middle position of the bottom surface of the mounting plate 1. A synchronizing rod 1208 is rotatably connected to the outside of the rotating shaft 1207 via a bearing. Connecting rods 1209 are rotatably connected to both ends of the synchronizing rod 1208. The ends of the two connecting rods 1209 are respectively rotatably connected to two moving plates 1202. When the left moving plate 1202 moves, the rotation of the synchronizing rod 1208 drives the right moving plate 1202 to move synchronously, ensuring the synchronicity and consistency of clamping on both sides of the clamping assembly 12, and improving the stability and reliability of clamping.
[0028] Furthermore, the clamping assembly 12 also includes a second cylinder 1210, which is fixedly connected to the front side of the bottom of the mounting plate 1. The output end of the second cylinder 1210 is fixedly connected to a connector 1211, which is fixedly connected to the front side of the left movable plate 1202. The second cylinder 1210 serves as the power source for the clamping assembly 12, and pushes the left movable plate 1202 to move through the connector 1211, thereby realizing the adjustment of the width of the clamping assembly 12.
[0029] Working principle: The external device of the split-type charging pile is placed at the center of the upper surface of the mounting plate 1, between the two sets of slots 10, and its rear side is roughly against the baffle 3 to achieve rear positioning. According to the workpiece size, the width of the clamping assembly 12 is adjusted by the second cylinder 1210. The second cylinder 1210 is activated, and the output end pushes the left moving plate 1202 to slide along the moving guide rail 1201 through the connecting piece 1211. The synchronous rod 1208 rotates around the rotating shaft 1207, driving the right moving plate 1202 to move synchronously, so that the guide roller 1206 on the inner side of the support plate 1204 fits against the left and right sides of the split-type charging pile. The first cylinder 4 is activated, and the output end pushes the connecting plate 5 to move backward along the guide rod 9. The extrusion plate 6 presses the front side of the workpiece through the rubber pad 7. When the extrusion plate 6 extrudes the split charging pile, if the split charging pile is positioned too far forward, i.e. there is a gap between the split charging pile and the baffle 3, the rotation of the guide roller 1206 during the operation of the first cylinder 4 can move the split charging pile to the rear within a certain range, ensuring that the rear side of the split charging pile is in close contact with the baffle 3, thus achieving gap compensation. The extrusion plate 6 and the baffle 3 cooperate to form a front and rear clamping force. After the workpiece is fixed, drilling, milling and other processing operations can be performed. After processing is completed, the first cylinder 4 and the second cylinder 1210 retract synchronously, the extrusion plate 6 returns to its original position with the connecting plate 5, the rubber pad 7 detaches from the workpiece, and the moving plate 1202 drives the support plate 1204 away from the split charging pile body. The operator can then directly remove the processed charging pile body.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
