Description

Technical Field

[0001] The present invention relates to the technical field of fixtures, and particularly to a fixture for an automobile steering knuckle housing. Background Art

[0002] The steering knuckle, also known as the "goat horn", is one of the important parts in the automobile steering axle, which can enable the automobile to drive stably and transmit the driving direction sensitively; the function of the steering knuckle is to transmit and bear the load at the front part of the automobile, support and drive the front wheels to rotate around the kingpin to make the automobile turn.

[0003] When machining the automobile steering knuckle housing, it is often necessary to punch a lot of connecting holes on the blank of the steering knuckle housing to facilitate the connection with multiple automobile parts, including the connecting holes for the automobile shock absorber strut, the brake caliper, the lower control arm, the steering tie rod, and the automobile wheel hub, etc.; these connecting holes often need to be punched on a three-dimensional punching machine. However, since the reference planes of various connecting holes are not in the same plane, and even the reference plane where the steering tie rod connecting hole is located is an inclined plane (neither a horizontal nor a vertical plane), it is necessary for workers to repeatedly clamp the blank of the steering knuckle housing and adjust the reference plane of the connecting hole to be in the same plane as the processing surface on the processing machine before punching operations can be carried out; this kind of repeated clamping operation not only has low efficiency, but also generates multiple errors during multiple clamping processes, resulting in low precision of the parts and affecting the assembly precision between the automobile steering knuckle and other parts. Summary of the Invention

[0004] To solve the problems raised in the above background art, the present invention provides a fixture for an automobile steering knuckle housing, with a clever structure, which can achieve one-time clamping, can process connecting holes on multiple different reference planes, has high clamping efficiency and high assembly precision.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A fixture for an automobile steering knuckle housing, including a fixture body. At the middle position of the upper end surface of the fixture body, a hemispherical groove is opened. A sphere is rotatably arranged in the hemispherical groove. A fixing groove is opened at the upper end of the sphere. A plurality of fixing bolts are threadedly arranged on the inner wall of the fixing groove, and the fixing bolts are arranged horizontally; a plurality of operating rods are fixedly arranged on the outer wall of the sphere. A first locking hole is opened at the outer end of the operating rod. A fixed support ear is fixedly arranged on the outer wall of the fixture body, and a second locking hole which is matched with the first locking hole is opened on the fixed support ear; a wire rope tensioner is arranged between the first locking hole and the second locking hole.

[0007] Further, an edge is fixedly arranged on the outer wall at the bottom end of the fixture body, and a threaded hole is opened on the edge.

[0008] According to the above technical solution, the setting of the edge facilitates the fixing of the fixture body on the processing machine tool, enabling cooperation with different processing machine tools and having a wider application range.

[0009] Furthermore, lubricating grease is provided between the hemispherical groove and the sphere.

[0010] According to the above technical solution, the setting of the lubricating grease facilitates the rolling of the sphere in the hemispherical groove.

[0011] Furthermore, a plurality of telescopic hydraulic cylinders are fixedly arranged on the upper end surface of the fixture body, and a processing platform is fixedly arranged at the output end of the telescopic hydraulic cylinder.

[0012] According to the above solution, the telescopic hydraulic cylinder can control the height of the processing platform.

[0013] Furthermore, a plurality of first support rods are fixedly arranged on the upper end surface of the fixture body. The upper end of the first support rod is rotatably connected to a rotating rod, and a first fixing hole is formed on the upper end surface of the rotating rod.

[0014] According to the above technical solution, the rotating rod can rotate and press against the upper end surface of the automotive steering knuckle housing.

[0015] Furthermore, a plurality of second support rods are fixedly arranged at positions corresponding to the first fixing holes on the upper end surface of the fixture body. The number of the second support rods is equal to that of the first support rods; second fixing holes that cooperate with the first fixing holes are provided on the second support rods.

[0016] According to the above technical solution, it is convenient to fix the rotating rod.

[0017] Furthermore, the hooks at both ends of the wire rope tensioner are respectively hung in the first locking hole and the second locking hole.

[0018] According to the above technical solution, it is convenient for the detachable connection of the wire rope tensioner.

[0019] Furthermore, the cross-section of the fixing groove is circular, and the diameter of the fixing groove is equal to the outer wall diameter of the automotive wheel hub connection hole on the automotive steering knuckle housing.

[0020] According to the above technical solution, it is convenient to fix the automotive steering knuckle housing in the fixing groove.

[0021] Furthermore, the processing platform is located at the rear half of the upper end surface of the fixture body, the sphere is located at the front half of the upper end surface of the fixture body, and the processing platform and the sphere are arranged in an alternating manner.

[0022] According to the above technical solution, it can prevent the processing platform from affecting the rolling of the sphere.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. The staff can fix the connection hole part on the steering knuckle housing for connecting with the vehicle wheel hub in the fixing hole through the fixing bolt. When it is necessary to punch and grind other parts of the vehicle steering knuckle housing, the first control lever can be rotated, and the spherical body rotates to adjust the machining reference surface on the steering knuckle housing fixed in the fixing groove to the horizontal plane; then the hydraulic cylinder is controlled to support the upper end surface of the machining platform on the lower end surface of the vehicle steering knuckle housing, which is convenient for punching; at the same time, the wire rope tensioner is hung on the first fixing hole and the second fixing hole to fix the steel ball. With one clamping, the processing of the connection ports on multiple non-reference surfaces can be completed. The clamping efficiency is high. By reducing the number of clamps, the clamping error can be reduced, and the assembly accuracy between the vehicle steering knuckle and other parts can be improved.

[0025] 2. By rotating the rotating rod to the upper end surface of the vehicle steering knuckle housing and using bolts to lock the first fixing hole, the connection hole on the vehicle steering knuckle housing, and the second fixing hole, the clamping of the vehicle steering knuckle housing can be made more stable.
