AI Technical Summary
The existing universal clamps cannot adapt to the shape of the high-voltage distribution box, which makes it difficult for the high-voltage distribution box to be clamped and may cause product deformation due to cylinder compression. At the same time, the universal clamps block the processing surface of the high-voltage distribution box, making it inconvenient to use.
A high-voltage distribution box box fixture is designed, including fixture base plate, pallet, support pad, air detection hole, elastic pin, crank and cylinder. The crank deflection is driven by air pressure to achieve point-to-point support and tightening of the distribution box blank, avoid product deformation, and link with the equipment through the gas detection hole to achieve anti-stopping function.
The fixture is compact in structure, which maximizes weight and material reduction. It uses the four-circular rotary table function to complete the processing of four processing surfaces in one process, avoiding positioning gaps, low maintenance costs for pneumatic power, avoiding product deformation, and implementing the anti-stupid function of fixture cylinders.

[0002] Usually, it runs under high-power vehicle electricity, which poses great challenges to the design of high-voltage distribution system and the selection of high-voltage components. Considering the space of the whole vehicle, the complexity of the whole vehicle structure and the cost, the industry widely adopts centralized high-voltage electrical system architecture for power distribution, of which the most important part is the high-voltage distribution box. The high-voltage power supply directly enters the high-voltage distribution box and is distributed to the system's high-voltage electrical products according to the needs of the system. In the production process, tooling is process equipment, also known as process equipment, which refers to the general term for various tools and additional devices used in the manufacturing process of products or parts, components and whole parts. In the process of processing the high-voltage distribution box, the corresponding tooling fixture is needed to clamp the high-voltage distribution box.
[0003] However, the existing universal clamp cannot adapt to the appearance structure of the high-voltage distribution box, which makes the high-voltage distribution box not only difficult to be compacted by the universal clamp, but also causes product deformation due to the compaction of the cylinder. In addition, the existing universal clamp will block the four processing surfaces of the high-voltage distribution box, especially the processing surface on the back of the three connecting rods of the high-voltage distribution box, resulting in multiple repeated clamping to adjust the processing position when processing different processing surfaces of the high-voltage distribution box, which is inconvenient to use.
[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a high-voltage distribution box body clamp is proposed. Utility Model Content
[0005] The purpose of the utility model is to provide a high-voltage distribution box body clamp to solve the problems raised in the above background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-voltage distribution box body clamp, including a clamp bottom plate, a support plate is fixed in the middle of the clamp bottom plate, and a support pad is arranged on the surface of the support plate, a gas detection hole is opened on the surface of the support pad, and the gas detection hole is connected to a gas detection connector, an elastic pin is arranged on the surface of the support plate, and a limit pin is matched on the side of the elastic pin.
[0007] Furthermore, a distribution box blank is placed above the support plate, and the prefabricated holes of the distribution box blank cooperate with two elastic pins to achieve positioning.
[0008] Furthermore, three through holes are opened on the surface of the fixture bottom plate, and the positions of the through holes correspond to the processing surface on the back side of the distribution box blank.
[0009] Furthermore, three mounting plates are fixed on the surface of the fixture bottom plate, and a crank is rotatably mounted on the top of the mounting plate.
[0010] Furthermore, the crank is rotatably installed in the middle of the pressing plate, and the front end of the pressing plate cooperates with the supporting pad to achieve point-to-point support and pressing of the distribution box blank.
[0011] Furthermore, the rear end of the pressing plate is rotatably connected to the output end of the cylinder, and the cylinder is connected to an external air source.
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] 1. The high-voltage distribution box body fixture of the present application has a compact structure, minimizes weight and material, and makes full use of the function of the turntable around, so that the four processing surfaces of the product can be completed in one process. By setting two elastic pins for positioning, the positioning gap caused by the different sizes of prefabricated holes in the distribution box blank is avoided. The high-voltage distribution box body fixture of the present application is powered by air pressure, and the later maintenance cost is low. When in use, the cylinder pushes the rear end of the pressure plate, so that the middle part of the pressure plate deflects with the crank as the center, and the distribution box blank is pressed through its front end. The front end of the pressure plate cooperates with the support pad to achieve point-to-point support and pressing of the distribution box blank, avoiding product deformation due to cylinder pressing. In addition, the support pads of the two workstations of the present application are provided with air inspection holes, which are linked to the equipment. If aluminum chips are pressed, the equipment will alarm and stop processing. Moreover, only one direction of the two workstations can be put into the fixture, which plays a role in preventing the fixture cylinder from being fooled. BRIEF DESCRIPTION OF THE DRAWINGS
