Technical Field

[0001] The utility model relates to the technical field of fixture processing technology, in particular to a steering knuckle forging and trimming fixture for a robot. Background Art

[0002] The steering knuckle is an important component in the automobile steering system, also known as the steering knuckle ball. It connects the steering rod and the steering arm, and plays the role of transmitting steering force and steering angle. The steering knuckle is usually made of metal materials with high strength and wear resistance. During the production process, the forging of the steering knuckle will produce scrap edges, which need to be separated from the steering knuckle forging. Utility Model Content

[0003] The utility model aims to provide a steering knuckle forging and trimming fixture for a robot, which has the effects of conveniently clamping the steering knuckle and conveniently processing the waste edge.

[0004] The above technical purpose of the utility model is achieved through the following technical scheme: a steering knuckle forging and trimming fixture for a robot, comprising a fixture body, a through cavity is provided in the middle of the fixture body, clamps are hinged on both sides of the end of the fixture body, an oil cylinder is fixed in the through cavity, the oil cylinder controls the opening or closing of the clamp through a hinge mechanism, and the clamp is provided with a forging clamping part and a waste edge clamping part.

[0005] By adopting the above technical solution, the clamp body is used in conjunction with the robot. When working, the cylinder controls the clamp to open or close through the hinge mechanism to clamp the steering knuckle forging or scrap edge, which is convenient for clamping the steering knuckle to process the scrap edge.

[0006] The utility model is further configured as follows: the hinge mechanism includes a first connecting rod fixed to the output end of the cylinder and a second connecting rod hinged at both ends of the first connecting rod, the second connecting rod is hinged with a connecting piece at one end away from the first connecting rod, the connecting piece is hinged to the end of the clamp body, and the clamp is fixed to the end of the connecting piece away from the clamp body.

[0007] By adopting the above technical solution, during clamping, the output end of the cylinder extends, thereby controlling the clamps at the ends of the connecting piece to approach each other through the first connecting rod and the second connecting rod to clamp the steering knuckle forging or the scrap edge; the output end of the cylinder returns, thereby controlling the clamps at the ends of the connecting piece to move away from each other through the first connecting rod and the second connecting rod to release the steering knuckle forging or the scrap edge.

[0008] The utility model is further configured as follows: a connecting groove for embedding the end of the connecting member is provided on one side of the clamp close to the connecting member, and the connecting member is threadedly connected with a connecting bolt extending into the connecting groove.

[0009] By adopting the above technical solution, the clamp is fixed to the end of the connecting piece by connecting bolts, which makes it easy to replace the clamp when it is worn, or adjust the position of the clamp relative to the connecting piece through the connecting groove according to processing needs.

[0010] The utility model is further configured as follows: the connecting bolts are provided in plurality.

[0011] By adopting the above technical solution, the firmness of the workpiece connection is improved and the clamping work is made more stable.

[0012] The utility model is further configured as follows: the forging clamping portion is configured as an arc-shaped inner groove.

[0013] By adopting the above technical solution, the arc-shaped inner groove adapts to the steering knuckle forging, which is conducive to the clamping of the steering knuckle forging and makes the clamping more stable.

[0014] The utility model is further configured as follows: the scrap edge clamping portion includes an inclined clamping surface inclined toward the arcuate inner groove and arranged on both sides of the clamp located at the arcuate inner groove, and a protrusion arranged on the inclined clamping surface, and the protrusion is configured to be located at the end of the clamp.

[0015] By adopting the above technical solution, the inclined clamping surface cooperates with the arc-shaped inner groove to clamp the steering knuckle forging, or cooperates with the protrusion to clamp the waste edge, thereby increasing the friction and gripping force between the clamping surface and the clamped object, thereby improving the clamping effect.

[0016] The beneficial effects of the utility model are:

[0017] 1. The clamp body is used in conjunction with the robot. When working, the oil cylinder controls the clamp to open or close through the hinge mechanism to clamp the steering knuckle forging or scrap edge, which is convenient for clamping the steering knuckle to process the scrap edge;

[0018] 2. Fix the clamp to the end of the connector by connecting bolts, so that the clamp can be replaced when it is worn, or the position of the clamp relative to the connector can be adjusted by connecting grooves according to processing needs;

[0019] 3. The inclined clamping surface cooperates with the arc-shaped inner groove to clamp the steering knuckle forging, or cooperates with the protrusion to clamp the waste edge, making the clamping work more stable. BRIEF DESCRIPTION OF THE DRAWINGS
