Description

Technical Field

[0001] This utility model belongs to the field of locomotive wheel rim production. Specifically, this utility model relates to a locomotive wheel rim clamping device. Background Technology

[0002] The H0-001 lathe is a specialized lathe for machining locomotive wheel rims. It can machine the inner diameter of locomotive wheel rims. During machining, the wheel rim blank needs to be hoisted onto the H0-001 lathe and clamped onto the chuck using four jaw bolts. After fixing and adjusting, the wheel rim blank is machined to the dimensions required for installation into the wheelset. However, because the H0-001 lathe is a heavy-duty lathe with a large chuck and heavy workpiece, and because the tread surface of the locomotive wheel rim is conical, the tread surface of the wheel rim and the top of the jaw bolts on the machine tool are in line contact or point contact, which makes it difficult for the operator to judge whether the clamping is tight. At the same time, the installation process also requires the wheel hub to be aligned and the jaw bolts adjusted to ensure that the coaxiality between the wheel hub and the lathe is consistent to ensure that the wheel hub is machined evenly. When tightening or loosening the jaw bolts, a slight oversight of the tightness of the other jaw bolts can cause the wheel rim to come off the jaws, resulting in an accident, which poses a significant safety hazard.

[0003] To address the aforementioned issues, patent application number 2020213172613 discloses a clamping tool for wheel hub processing, comprising a base, a first supporting shaft, a driven large gear turntable, a clamping adjustment device, a second supporting shaft, a first driving small gear turntable, a third supporting shaft, a second driving small gear turntable, two sets of first rotating rods, and two sets of first rotating handles. The base has a groove, the bottom of the first supporting shaft is rotatably connected to the base via a bearing device, and the bottom end of the driven large gear turntable is connected to the top end of the first supporting shaft. The clamping adjustment device is fixed on the driven large gear turntable, but this tool fails to solve the aforementioned problems. Utility Model Content
