[0024] In the utility model, three auxiliary pressing parts and four auxiliary supporting parts are added at the distal positions of positioning, supporting and pressing, as well as at important processing positions, and the air cylinders are replaced with hydraulic cylinders, so that the pressure is stable, high-speed and efficient processing can be carried out, and the stability of quality and efficiency is improved.
[0025] Specifically, Figure 2 It is a top view of a fixture for a new energy electric control housing processing center, Figure 3 It is a schematic diagram of hiding Figure 2 All pressing plates. The three main pressing parts include a first main pressing hydraulic cylinder 11 and a first main pressing plate, a second main pressing hydraulic cylinder 12 and a second main pressing plate, and a third main pressing hydraulic cylinder 13 and a third main pressing plate, and are distributed in a three-point structure; the first main pressing hydraulic cylinder 11 is equipped with a first support platform 111, on which a first plane support block 112 and a first spring positioning pin 113 are arranged; the second main pressing hydraulic cylinder 12 is equipped with a second support platform 121, on which a second plane support block 122 is arranged; the third main pressing hydraulic cylinder 13 is equipped with a third support platform 131, on which a third plane support block 132 and a third spring positioning pin 133 are arranged.
[0026] In this embodiment, the first main pressing plate, the second main pressing plate, and the third main pressing plate are respectively installed on three hydraulic cylinders to press the new energy electric control housing at three points. The first spring positioning pin 113 and the third spring positioning pin 133 elastically position and clamp the new energy electric control housing to prevent damage to the housing. The first plane support block 112, the second plane support block 122, and the third plane support block 132 are all plane supports and adopt a cylindrical surface structure. The surface support is more stable than the point support. The first spring positioning pin 113 and the third spring positioning pin 133 can limit the freedom in the XY direction.
[0027] As Figure 2 shown, the three auxiliary pressing parts include a first auxiliary pressing hydraulic cylinder 21 and a first auxiliary pressing plate, a second auxiliary pressing hydraulic cylinder 22 and a second auxiliary pressing plate, and a third auxiliary pressing hydraulic cylinder 23 and a third auxiliary pressing plate, and are distributed in a three-point structure.
[0028] In this embodiment, the first auxiliary pressing plate, the second auxiliary pressing plate, and the third auxiliary pressing plate are respectively installed on three hydraulic cylinders, and are used to press the new energy electronic control housing at three points, forming a six-point pressing together with the three points of the main pressing, so that the new energy electronic control housing is more stable.

At the same time, when supporting the large-area suspended part of the new energy electronic control housing, using the support cylinder to give a fulcrum, and with the mutual cooperation of the three auxiliary pressing members, the resonance phenomenon caused by the unstable factors in the processing can be eliminated, the processing speed can be improved, and there is no need to worry about risks such as the product not being clamped tightly with multi-point clamping.
