Hub unit finished product turning lathe

Abstract

The invention discloses a hub unit finished product turning lathe. The lathe comprises a base, a cutting edge, a cutter holder and a first feeding device, wherein positioning profiling is arranged onthe base, a lifting base is arranged on one side of the base through a first lifting structure, a top base is arranged on the lifting base, a height measuring instrument is arranged on the top base, atop column is rotationally arranged on the top base, the top column is driven by a first motor, a second feeding device for driving the top base to move is arranged on the lifting base, the cutting edge is fixed on the cutter holder, a sliding base is arranged on the base, the sliding base is driven by the first feeding device, the sliding base is connected with the cutter holder through a secondlifting structure, and the first feeding device, the height measuring instrument, the first motor, the first lifting structure and the second lifting structure are all connected with a control device. The lathe can adjust the height of the cutting edge according to the height of the end faces of hub units, so that the flange end faces of the hub units with different tolerance ranges can be turned, and the lathe can be applied to the different types of hub units.

Description

technical field [0001] The invention belongs to the technical field of wheel hub processing equipment, in particular to a wheel hub unit finished car lathe. Background technique [0002] The main function of the hub unit is to bear the load and provide precise guidance for the transmission of the hub. It bears both the axial load and the warp load. It is a very important part of the auto parts. After the assembly of the hub unit is completed, in order to ensure the smoothness of the end face of the flange and the accuracy of subsequent installation, it is generally necessary to re-turn the end face of the flange. In the prior art, a horizontal lathe is generally used to turn the end face of the flange. When the wheel hub unit of the same model is turned, generally after the hub unit is fixed on the lathe, the end face of the turning flange is fed through the turning tool, and even for the same type of hub unit, each hub unit has ± 20 to 50 wires. Generally, the thickness of...

Problems solved by technology

After the assembly of the hub unit is completed, in order to ensure the smoothness of the end face of the flange and the accuracy of subsequent installation, it is generally necessary to re-turn the end face of the flange. In the prior art, a horizontal lathe is generally used to turn the end face of the flange. When the wheel hub unit of the same model is turned, generally after the hub unit is fixed on the lathe, the end face of the turning flange is fed through the turning tool, and even for the same type of hub unit, each hub unit has ± 20 to 50 wires. Generally, the thickness of the end face of the flange is about 6 wires. Using the traditional method, the end face of some flanges needs to be cut off a very thick piece, and some of them cannot be turned at all, so the turning of the end face of the flange cannot be completed at one time.
