[0002] A turbocharger is actually an air compressor that increases the intake air volume by compressing air. It uses the inertia impulse of the exhaust gas discharged from the engine to drive the turbine in the turbine chamber. Heat treatment is a process of heating and cooling metal materials to change their structure and properties. Sometimes, secondary heat treatment is required for the stability of parts. The inclined retaining ring of a turbocharger refers to a part used to position and support the central shaft of the turbocharger, and the performance of the part is strengthened by heat treatment during processing.

Between the two inner support limiting members 21, there are two telescopic rods 3 for positioning. When the inner diameter of the workpiece is opposite to the inner support limiting member 21, the distance between the two outer support surfaces 212 is equal to the inner diameter of the workpiece. At this time, the positions of the two inner support limiting members 21 can be controlled. The inner support limiting member 21 slides on the bottom fixing plate 22, and the workpiece can be restricted outside the inner support limiting member 21. When the inner support limiting member 21 moves, the telescopic rod 3 can perform positioning. And through the movement of the slider 23 on the inner support limiting member 21 in the chute 221, the inner support limiting member 21 faces the inner position of the workpiece. When fixing the inner support limiting member 21, the first bolt 24 can be screwed to tighten the first bolt 24 on the bottom fixing plate 22 to fix the position of the inner support limiting member 21. Multiple workpieces can be clamped for heat treatment. If secondary heat treatment is to be carried out, the workpiece can be clamped in the transposition fixing area 4 to change the clamping contact position, which is beneficial to the heat treatment of the workpiece and improves the heat treatment effect. When clamped in the transposition fixing area 4, the position of the bottom fixing plate 22 can be controlled. By operating on the second bolt 25, the bottom fixing plate 22 can be slid on the installation auxiliary shaft 11 or the position of the bottom fixing plate 22 can be fixed, so that the bottom of the bottom fixing plate 22 is opposite to the top of the inner support limiting member 21, clamping the side of the workpiece to complete the fixation.

The first bolt 24 can be screwed to tighten the first bolt 24 on the bottom fixing plate 22 to fix the position of the inner support limiting member 21. Multiple workpieces can be clamped for heat treatment.

[0023] The bottom of the inner support limiting member 21 is fixedly connected with a slider 23, and the bottom fixing plate 22 is provided with a chute 221. The slider 23 slides in the chute 221. Through the movement of the slider 23 on the inner support limiting member 21 in the chute 221, the inner support limiting member 21 faces the inner position of the workpiece.

At this time, the positions of the two inner support limiting members 21 can be controlled. Slide the inner support limiting member 21 on the bottom fixing plate 22. The workpiece can be restricted outside the inner support limiting member 21. When the telescopic rod 3 moves within the inner support limiting member 21, positioning can be carried out. And through the movement of the slider 23 on the inner support limiting member 21 in the chute 221, the inner support limiting member 21 faces the inner position of the workpiece. When fixing the inner support limiting member 21, the first bolt 24 can be screwed to tighten the first bolt 24 on the bottom fixing plate 22 to fix the position of the inner support limiting member 21.
