[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the scope of implementation of the present invention is not limited thereto.

[0014] like Figure 1 As shown, a machining device for a steering knuckle housing of the present embodiment comprises a base plate 1, wherein the base plate 1 is provided with two symmetrical clamping positions, each symmetrical clamping position is provided with a support head 2, a support head 3 and a support head 4 in a triangular shape, the tops of the support heads 1 2, the support heads 2 3 and the support heads 3 4 are a crushed diamond structure composed of a large number of small squares evenly distributed, and correspondingly, a pressure plate 1 5, a pressure plate 2 6 and a pressure plate 3 7 are provided above the support heads 1 2, the support heads 2 3 and the support heads 3 4, respectively, the pressure plates 1 5, the pressure plates 2 6 and the pressure plates 3 7 are all slidably connected to a screw fixed to the base plate 1, and are pressed downward by a nut threadably connected to the screw, and an auxiliary support head 8 is also provided next to the support head 3 4.

[0015] This embodiment uses a support head with a broken drill structure to contact the knuckle shell, thereby increasing the friction between the two in the horizontal direction, thereby fixing the knuckle shell in the horizontal direction. Each pressure plate is aligned with the support head below, which prevents the workpiece from shifting during processing while pressing the workpiece; because the processing surface of one end of the workpiece is not directly above the support head 3 4, and the offset is large, the auxiliary support head 8 is set below the processing surface in this embodiment.

[0016] The pressing plate 1 5 and the pressing plate 2 6 of the present embodiment both press two workpieces at the same time, thereby eliminating the need for a support column and improving the clamping effect of the fixture.

[0017] In order to prevent the workpiece from flying out of the fixture due to excessive horizontal force during processing, in this embodiment, anti-collapse plates 9 are further provided at both ends of the base plate 1, and the anti-collapse plates 9 are provided with grooves for engaging with the two ends of the steering knuckle housing.

[0018] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, and for the convenience of describing the technical solution, the front, rear, left, right, top, middle, and bottom directions adopted are based on the settings in the accompanying drawings, rather than limiting the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
