Description

Technical Field

[0001] The utility model relates to a tool for processing elevator parts, in particular to a tool for processing a thin hub. Background Art

[0002] Elevator parts include many hub components. When materials with sufficient strength are selected, thin hubs with relatively thin thickness can be designed as parts.

[0003] In the existing design, it is necessary to machine an annular groove on the outer edge of the hub to position the rope wrapped around it. Compared with the method of using a bent metal plate with a groove to form the hub, our company prefers to adopt a solution of directly machining the groove on the outer edge surface of the integrally formed barrel-shaped metal plate. However, in the actual processing process, it was found that during the cutting process of the groove for the thin hub, the inner ring was deformed due to the relatively weak processing area.

[0004] Existing clamps for clamping wheel hubs for processing, such as the Chinese patent authorization announcement number: CN216829822U, which was publicly authorized on June 28, 2022, are an automatic clamping wheel hub protective shell production and processing clamp, including a clamp body, which includes a connecting section, one end of which is fixedly connected to a lathe; and a clamping assembly, which is connected to the end of the connecting section away from the lathe, and the clamping assembly is provided with an ejection mechanism. The utility model uses the principle of rotating centrifugal force to clamp the product for processing, so that thin parts will not be deformed when processing, the workpiece will not have vibration marks, and the size can be processed once. Utility Model Content

[0005] Aiming at the shortcomings of existing technologies.

[0006] The purpose of the utility model is to:

[0007] 1. Provide a wheel hub processing tooling, and design a unique processing tooling to solve the problem of deformation during thin wheel hub processing.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a thin hub processing tool, comprising a main shaft, a rear plate, a front plate and a support member, the rear plate is fixed on the main shaft, the support member is fixed on the rear plate, the front plate is detachably connected to the support member, the support member is cylindrical, and the outer surface shape of the support member corresponds to the inner wall shape of the workpiece.

[0009] The cylindrical support member increases the effective thickness of the thin hub workpiece during processing, so that the thin hub workpiece will not be deformed when processing the grooves on its outer surface, which may cause the workpiece to be scrapped.

[0010] Optionally, the rear plate is disc-shaped, with a center hole for the main shaft to pass through in the center of the rear plate, a fixing plate is provided on one end of the main shaft, a plurality of first fixing holes are provided on the fixing plate, and second fixing holes corresponding to the first fixing holes are provided near the center hole.

[0011] Optionally, the rear plate has a plurality of third fixing holes in a circumferential array around the periphery, and the support member is provided with fourth fixing holes corresponding one-to-one to the third fixing holes.

[0012] Optionally, there are a plurality of front panels, a fifth fixing hole is provided on a side of the support member close to the front panel, and a sixth fixing hole corresponding to the fifth fixing hole is provided on the front panel.

[0013] All of the above fixing holes can be provided with internal threads to accommodate bolts.

[0014] Optionally, there are several support members, and the number of the support members corresponds to the number of grooves that need to be processed on the outer surface of the workpiece.

[0015] Optionally, elastic parts are designed between the supporting parts so that the tooling as a whole can adapt to thin hub workpieces of different widths.

[0016] Preferably, the front plate has a pressing protrusion corresponding to the support member, which is used to press the support member to reduce the gap between the support member and the thin hub workpiece.

[0017] The utility model has the beneficial technical effect that the effective thickness of the thin hub workpiece during processing is increased in disguise through the cylindrical support member, so that the thin hub workpiece will not be deformed when processing the grooves on its outer surface, which may cause the workpiece to be scrapped.
