Description

Technical Field

[0001] This utility model belongs to the field of axle processing technology, specifically relating to a tooling for processing defects in rail vehicle axles. Background Technology

[0002] The purpose of machining defects on rail vehicle axles is to create standard defects on the axles for comparison with actual defects, thus providing a standard for evaluating actual defects. The machining locations for standard defects on the axles include not only the circumferential surface but also the transition arc surface at the diameter change position. This requires the cutting tool to be deflected before machining. However, on the company's existing machine tools, the deflection direction of the cutting tool is perpendicular to the axis of the axle after clamping, making it impossible to machine axle defects. Therefore, a new tooling suitable for machining axle defects needs to be designed. Utility Model Content

[0003] This utility model provides a tooling for machining defects in rail vehicle axles to address the above-mentioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A tooling for machining defects in rail vehicle axles includes a worktable with two parallel guide rails fixedly mounted on it. Two sets of support components are slidably mounted on the two guide rails to support the axle. Each support component includes a sliding table slidably mounted on the two guide rails. Support plates are fixedly mounted on the front and rear sides of the upper surface of the sliding table. Two support wheels are rotatably mounted between the two support plates and are arranged symmetrically from left to right.

[0006] Furthermore, a second guide rail is provided between the two first guide rails. The second guide rail is fixedly connected to the worktable. A slider is slidably provided on the second guide rail. An inverted L-shaped block is fixedly provided on the slider. A positioning rod is slidably provided on the horizontal part of the L-shaped block. A limit ring is fixedly provided on the upper middle part of the positioning rod. A spring is provided between the limit ring and the upper surface of the L-shaped block. The spring is sleeved on the positioning rod. A limit rod is fixedly provided at the lower end of the positioning rod. The limit rod is located below the horizontal part of the L-shaped block. The upper end of the positioning rod is used to cooperate with the positioning hole on the circumferential surface of the positioning sleeve, thereby realizing the positioning of the rotation angle of the axle. There are multiple positioning holes, which are evenly opened on the circumferential surface of the positioning sleeve. A groove corresponding to the end face of the axle is opened on the side of the positioning sleeve near the axle. A through hole is opened on the other side of the positioning sleeve. A limit bolt is provided in the through hole. The limit bolt passes through the through hole and is threadedly connected to the threaded hole on the end face of the axle, so as to realize the fixed connection between the positioning sleeve and the axle.

[0007] Furthermore, a connecting plate is fixedly installed on one side of the support plate, and a stop bolt is threaded to the other end of the connecting plate, with the end of the stop bolt abutting against the support wheel.

[0008] Furthermore, a positioning bolt is threaded onto one side of the sliding table. The end of the positioning bolt passes through the sliding table and abuts against the guide rail to fix the sliding table.

[0009] Furthermore, a second positioning bolt is threaded onto the slider, and the end of the second positioning bolt passes through the slider and abuts against the second guide rail to fix the slider.

[0010] Furthermore, a stop rod is fixedly installed on the vertical part of the L-shaped block. By rotating the limit rod to below the stop rod, the positioning rod is kept disengaged from the positioning hole, so as to facilitate the loading and unloading of the axle.

[0011] Furthermore, multiple through holes are provided on the side of the positioning sleeve to facilitate connection with threaded holes on the end faces of axles of different specifications.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] The guide rail of this utility model is set in a direction that is perpendicular to the axis of the axle after the original three-jaw chuck clamps the axle and is in the same direction as the deflection direction of the cutting tool on the machining tool. It can realize the processing of the transition arc surface at the diameter change position of the axle and is suitable for processing standard defects of the axle.

[0014] This invention enables the axle to rotate at a fixed angle, which is beneficial for the processing of standard defects in the axle. This invention also enables the axle to move by sliding the sliding table and the slider, which is beneficial for the processing of standard defects in the axle.

[0015] This utility model is equipped with a stop bolt, which can fix the support wheel, thereby fixing the radial position of the axle and preventing it from rotating during processing. Attached Figure Description
