Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wheel hub processing equipment, and particularly relates to a positioning tool of a wheel hub transfer line. BACKGROUND

[0002] A wheel hub is an important running component of an automobile. At present, most wheel hubs are manufactured by using a die casting process. After being die cast, the wheel hub still needs to be subjected to a series of processes such as powder spraying and deburring. The wheel hub generally has a size of 20 inches, 22 inches, 24 inches or the like, and the single weight of the blank is 40-50 kg, so it is very difficult for an operator to carry. At present, most wheel hub production plants use mechanical conveying. For example, a conveying device shown in the drawings of patent No. CN217417150U is used to place a die cast wheel hub blank on a supporting column by using a mechanical arm. However, the mechanical arm cannot accurately align the position when placing. At present, a positioning device is used to position a conical positioning column as shown in the drawings of the above patent. In actual use, when the mechanical arm places the wheel hub blank, the wheel hub falls a little bit, the conical positioning column collides with the wheel hub, and even the wheel hub directly slides from the side of the positioning column and falls to the ground to cause a bruise. This causes the wheel hub blank to be scrapped, greatly increases the production cost of the plant, and seriously affects the production efficiency of the plant.
