Embodiment Construction

[0022] see figure 2 , a hub hole machining method provided in an embodiment of the present invention includes the following steps:

[0023] Place the wheel on the self-centering chuck 7 of the processing equipment.

[0024] The self-centering chuck 7 supports the hub end face of the wheel.

[0025] The hub end face 4 of the wheel is used as the positioning datum.

[0026] Self-centering chuck 7 clamps the wheel.

[0027] The processing equipment touches the upper end surface of the hub hole of the wheel to obtain the coordinate value in the Z direction.

[0028] The processing equipment processes the hub hole according to the Z coordinate value and the processing size of the hub hole.

[0029] Specific embodiments of the application Since the wheel is placed on the self-centering chuck 7, the self-centering chuck 7 supports the hub end face of the wheel, and the wheel hub end face 4 is used as a positioning reference, and the self-centering chuck 7 clamps the wheel , the...

Abstract

The invention discloses a machining method for a hub hole, which belongs to the technical field of railway wagon wheel machining. The hub hole processing method includes the following steps: placing the wheel on a self-centering chuck of a processing device; the self-centering chuck supports the hub end face of the wheel, and uses the hub end face of the wheel as a positioning reference; The self-centering chuck clamps the wheel; the processing equipment touches the upper end surface of the hub hole of the wheel to obtain the Z-direction coordinate value; The hub bore is machined. The hub hole processing method of the present invention effectively improves processing efficiency, reduces unnecessary operations, reduces labor intensity, saves manufacturing cost, and is simple and practical.

Description

technical field [0001] The invention relates to the technical field of wheel processing, in particular to a method for processing a hub hole of a railway freight car. Background technique [0002] see figure 1 , The railway wagon wheel is composed of three parts: rim 1, spoke 2 and hub 3. Wherein, the outer end surface of the hub is called the hub end surface 4 , the outer end surface of the rim is called the rim end surface 5 , and the outer circular part of the rim is called the tread surface 6 . When the wheel is provided to the truck manufacturer, the inner hole part is a blank, and then the inner hole of the wheel hub 3 and the upper and lower chamfers R are finished by each truck manufacturer, and then assembled with the axle to form a wheel set. [0003] However, in the prior art, the inner hole of the hub 3 and the upper and lower chamfers R are finished. Since the distance between the end surface of the hub 3 and the end surface of the rim 1 is uncertain (the maxi...
