Description

Technical Field

[0001] This invention relates to the field of automotive parts processing technology, and in particular to a special machine for milling the outer diameter of a fist. Background Technology

[0002] Most automotive parts are manufactured through casting. However, for special installation requirements and usage scenarios, conventionally produced automotive parts need to be machined to meet installation requirements and avoid interference during installation. However, the machining accuracy does not need to reach high precision. Using high-precision machining centers to machine automotive parts increases processing costs and time, and also affects the processing time of other high-precision automotive parts. Manual machining increases labor intensity and affects processing requirements, especially for automotive parts such as axles. Most axles are cast from molds, and some parts are not curved. Under certain installation or operating conditions, unmachined axles can cause interference. Therefore, the applicant has designed a special machine for milling the outer diameter of fists to address the above situations. Summary of the Invention

[0003] The problem solved by this invention is to provide a special machine for milling the outer diameter of a fist, which has a simple structure, is easy to operate, realizes the milling of automotive parts, and speeds up work efficiency.

The upper end of the support rod 102 is fixedly connected to the lower part of the machining plate 101. This fixed connection can be achieved by welding. The support rods 102 can be made from processed scrap material. Since the applicant is a casting production enterprise, the scrap material can be recycled and reused. The machining plate 101 is semi-circular in top view. This semi-circular design reduces the amount of material used in the machining plate 101 and also facilitates processing. A positioning hole is provided at the center of the machining plate 101. A positioning column is rotatably mounted on the machining base, and the positioning column is rotatably mounted at the positioning hole of the machining plate 101.

The power section 203 is rotatably mounted on the processing plate 101, and a driven gear 205 is correspondingly mounted on the power section 203. The rotation of the power section 203 drives the rotation of the positioning section 202, which in turn drives the rotation of the automotive parts.

The support 403 includes a seat body mounted on the support plate 401. A pulley 404 is rotatably mounted on the lower part of the seat body. The pulley 404 can provide assistance and sliding for the rotation of the seat body, reducing the friction between the seat body and the processing plate 101. The seat body is provided with spaced limiting plates. The limiting plates and the seat body form a limiting space for limiting the workpiece.
