Description

Technical Field

[0001] The utility model relates to the technical field of spraying fixtures, in particular to a spraying fixture for an automobile steering knuckle. Background Art

[0002] The steering knuckle is one of the main parts of the steering axle of the car. After being cast, the steering knuckle needs to be painted. The existing technology mostly adopts the method of hanging the steering knuckle for painting.

[0003] For example, the patent with authorization announcement number CN203140220U discloses a car steering knuckle painting hanger, which includes upper and lower rings and several connecting columns for connecting the upper and lower rings. Several hooks for hanging the car steering knuckle are provided from top to bottom on the connecting columns. The steering knuckle is suspended by hooking. However, for some steering knuckle castings, there is no hooking position. The mounting hole on the steering knuckle is produced by machining after painting. Therefore, for such steering knuckles, it is necessary to install a clamp on the hanger to clamp the steering knuckle, so as to realize the suspension of the steering knuckle casting on the hanger.

[0004] However, the current clamps lack protective devices, which causes the paint liquid to adhere to the clamp during painting, making it difficult to subsequently open and clamp the clamp. Utility Model Content

[0005] The utility model aims to provide a spraying fixture for an automobile steering knuckle, which has the effect of protecting the fixture.

[0006] The above technical purpose of the present utility model is achieved through the following technical solutions: a car steering knuckle spraying fixture, including a clamp and a protective cover mounted on the clamp, a clamping opening is provided at the bottom of the protective cover, the clamp includes two clamping rods hinged to each other, the clamping ends are respectively provided with a clamping part and a pushing part, the hinge point of the two clamping rods is located between the clamping part and the pushing part, a pushing rod is threadedly connected to the pushing part, and the pushing rod is rotated to push the two pushing parts away from each other, and the clamping part extends out of the clamping opening.

[0007] By adopting the above technical solution, the protective cover wraps the clamp inside the protective cover, and the clamping part extends out of the protective cover, which prevents the paint liquid from adhering to the hinge of the two clamping rods and the threaded connection between the push rod and the pushing part during painting, thereby achieving protection of the clamp.

[0008] The present invention is further configured to include a suspension hook, wherein the ends of the two pushing parts are respectively connected to a suspension chain, and one end of the suspension chain away from the pushing part is fixedly connected to the suspension hook.

[0009] By adopting the above technical solution, the hook is connected to the end of the pushing part through the suspension chain, and the hook realizes the suspension of the clamp.

[0010] The present invention is further configured as follows: a connecting port for the suspension chain to pass through is provided on the top of the protective cover, and a connecting buckle located between the two suspension chains is provided on the connecting port.

[0011] By adopting the above technical solution, the connecting buckle partially closes the connecting port, leaving only a port for the hanging chain to extend out, thereby reducing the paint liquid from entering the protective cover through the connecting port on the top of the protective cover.

[0012] The utility model is further configured as follows: a rod hole for the end of the push rod to extend out is provided on the side of the protective cover, and one end of the push rod extending out of the rod hole is connected to a rotating handle.

[0013] By adopting the above technical solution, the rotation handle drives the push rod to rotate, thereby driving the two clamping parts to approach each other to achieve clamping of the steering knuckle.

[0014] The utility model is further configured as follows: a protective tube is sleeved on the push rod, the end of the protective tube extends into the rod hole, a limiting portion is provided at one end of the protective tube extending into the rod hole, and positioning grooves are provided on the inner wall of the protective sleeve on both sides of the limiting portion, and both sides of the limiting portion extend into the positioning grooves respectively.

[0015] By adopting the above technical solution, the protective tube is sleeved on the push rod to protect and shield the push rod, further reducing the need to replace the protective tube when too much paint liquid adheres to the protective tube, thereby improving the practical life of the clamp. When the protective tube is connected to the push rod, the limiting part extends into the positioning groove, thereby improving the stability of the connection of the protective tube to the push rod.

[0016] The beneficial effect of the utility model is that the protective cover wraps the clamp inside the protective cover, and the clamping part extends out of the protective cover, which prevents the paint liquid from adhering to the hinge of the two clamping rods and the threaded connection between the push rod and the push part during painting, thereby achieving protection of the clamp.
