[0002] Automobile chassis security parts are important parts of the automobile body system. The structure of this type of products is basically similar, with only slight differences in size. In the past, several sets of fixtures were used to process this type of products for one size, the processes were scattered, and the adjustment of the fixtures was labor-intensive and time-consuming. The tooling investment was large, and the processing accuracy was not ideal. Therefore, in order to improve product accuracy, reduce tooling investment, and improve the efficiency of tooling adjustment, it is necessary to use a universal hydraulic fixture on the machining center. Utility Model Content

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a universal hydraulic clamp for a new type of automobile chassis security part, including a clamp body, a pull-down hydraulic cylinder installed on the clamp body, a pull-down connecting shaft installed on the pull-down hydraulic cylinder, a detachable bridge-type pressure plate installed in the groove of the pull-down connecting shaft, a pressure head installed in the middle of the bridge-type pressure plate with an interference fit, a fixed adjustment support one installed on the clamp body, an auxiliary support hydraulic cylinder installed on the clamp body, a side support one installed on the clamp body, a side adjustment support nail one installed on the side support one, a fixed adjustment support two installed on the clamp body, a side support two installed on the clamp body, and a side adjustment support nail two installed on the side support two.

[0005] Furthermore, the clamp body has two side adjustment support pins to form a V-shaped positioning structure, which can ensure the position accuracy of the large hole and the uniformity of the large hole margin.

[0006] Furthermore, the two fixed adjustment supports 1 and 2 of the clamp form three points and one plane, and the machining allowance can be adjusted.

[0007] Furthermore, the clamping body is equipped with four auxiliary supporting hydraulic cylinders to improve the clamping rigidity of the parts and reduce vibration during processing.

[0008] Furthermore, when working, the pressing head in the middle of the bridge-type pressing plate of the fixture presses on the center position of the triangular area formed by the fixed adjustment support to ensure that the parts are pressed tightly and will not flip over.

[0009] Furthermore, the fixture can switch to process similar products by adjusting and replacing components such as the fixed adjustment support, the side adjustment support, the pull-down connecting shaft, and the bridge pressure plate.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] The utility model discloses a universal hydraulic clamp for automobile chassis security parts, which is installed on a machining center and utilizes the characteristics that automobile chassis security parts have different sizes but similar appearance and structure. A clamping body, a pull-down hydraulic cylinder, a pull-down connecting shaft, a detachable bridge-type pressure plate, a pressure head, a fixed adjustment support, an auxiliary support hydraulic cylinder, a side support seat, and a side adjustment support nail can be used to realize the processing of various automobile chassis security parts, so that the tooling investment is small, the adjustment and switching efficiency is high, the labor intensity is small, and the product quality is high and stable.
