Technical Field
[0001] This utility model relates to the field of wheel hub processing equipment technology, and more specifically to a wheel hub spoke edge waste material cutting device. Background Technology
[0002] After the existing car wheel hub is cast, there will be excess molding material on the wall of the empty groove around the spokes. The current method is to cut it off manually later, which is inefficient.
[0003] A wheel hub typically has five or more spokes. Operators need to continuously cut the spokes and rotate the hub according to the cutting position, which is very labor-intensive and increases labor costs. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a waste material cutting device for the edge of wheel hub spokes. It can directly cut off the excess shaped material around the spokes of the wheel hub, and then only manual grinding of the local wall surface is required, which greatly reduces the amount of manual labor and has high processing efficiency.

The wheel hub to be processed is inserted into the bottom support sleeve, and the bottom surface of the wheel hub spoke is close to the top surface of the annular protrusion.
[0007] The top surface of the top plate of the bottom support sleeve is formed with a plurality of PCD hole positioning posts, which are inserted into the PCD holes at the hub of the corresponding wheel hub.
[0008] An upper support frame is fixed on the top surface of the top plate of the frame. A stamping cylinder is fixed in the middle of the top surface of the top plate of the upper support frame. The bottom end of the push rod of the stamping cylinder extends out of the bottom surface of the top plate of the upper support frame and is fixed with a lifting plate. A lower horizontal fixing plate is provided below the lifting plate. Multiple cutting blades are fixed on the bottom surface of the lower horizontal fixing plate. The bottom of the cutting blades faces one side wall of the corresponding spoke.
[0009] The top surface of the lower horizontal fixed plate is fixed with multiple vertical guide posts. The top of the vertical guide posts extends out of the top of the corresponding vertical through holes formed on the lifting plate. External threads are formed on the outer side wall of the top of the vertical guide posts. The upper locking nut is screwed onto the external thread at the top of the vertical guide post. The buffer spring is inserted into the vertical guide post. The bottom surface of the upper locking nut presses against the top surface of the lifting plate. The top of the buffer spring is applied to the bottom surface of the lifting plate. The bottom end of the buffer spring is applied to the top surface of the lower horizontal fixed plate.
[0010] Multiple upper vertical guide rods are fixed on the top surface of the lifting plate, and the upper vertical guide rods are inserted into the vertical guide through holes formed on the top plate of the upper support frame;
[0011] The PCD hole positioning post is a stepped post with a large-diameter post at the bottom and a small-diameter post at the top. The outer wall of the top end is a conical wall. The top of the PCD hole positioning post is inserted into the corresponding PCD hole. The bottom surface of the hub of the wheel hub presses against the top surface of the large-diameter post of all the PCD hole positioning posts.
[0012] The bottom surface of the top plate of the bottom support sleeve is formed with a downwardly extending lower sleeve support part, and the bottom surface of the lower sleeve support part presses against the top surface of the top plate of the frame.

[0015] The outstanding effect of this utility model is:
[0016] It can directly cut off the excess molding material around the spokes of the wheel hub, and then only requires manual grinding of the local wall surface, which greatly reduces the amount of manual labor and has high processing efficiency. Attached Figure Description
