[0002] The existing shaft-mounted brake disc wear detection ruler uses the wear limit step of the shaft-mounted brake disc as the supporting plane. Since there is no wear limit step on the inner side of some shaft-mounted brake discs, there is no wear limit step on the inner side when using the existing wear detection ruler. When the shaft-mounted brake disc is installed, the reference cannot be positioned, and it cannot provide effective support for the subsequent judgment of the shaft-mounted brake disc scrapping and process flow judgment, resulting in the scrapping or rework of the shaft-mounted brake disc due to inaccurate data.

Embodiment Construction
[0016] Such as Figure 1-Figure 2 As shown, a shaft-mounted brake disc wear detection ruler provided by the present invention includes an arc-shaped rod 2 and magnetic rods 1 symmetrically arranged on both sides of the arc-shaped rod 2, and a sliding seat 3 is arranged on the arc-shaped rod 2. A slide bar 4 is arranged inside the slide seat 3, and a dial indicator 5 is installed on the slide bar 4. The magnetic bar 1 is adsorbed on the outer circle of the shaft-mounted brake disc 100, forming a positioning reference that does not rely on the wear limit step, and the slide bar 4 The sliding dial indicator 5 takes the wear limit step as the zero point to measure the outer circle limit, the inner circle limit and the lowest point limit of the shaft-mounted brake disc 100 .
[0017] A method for detecting a shaft-mounted brake disc wear detection ruler, comprising the following steps:
[0018] Step 1: Adsorb the magnetic bar 1 on the outer circle of the shaft-mounted brake disc 1...

The shaft-mounted brake disc abrasion detection ruler comprises an arc-shaped rod and magnetic bars symmetrically arranged on the two sides of the arc-shaped rod, a sliding seat is arranged on the arc-shaped rod, a sliding rod is arranged in the sliding seat, a dial indicator is installed on the sliding rod, and the magnetic bars are attracted to the outer circle of a shaft-mounted brake disc. The outer circle limit, the inner circle limit and the lowest point limit of the shaft-mounted brake disc are measured by sliding the dial indicator through the sliding rod and taking the abrasion limit step as a zero point. According to the shaft-mounted brake disc abrasion detection ruler and the detection method provided by the invention, the abrasion detection requirement of a shaft-mounted brake disc without an abrasion limit step on the inner side can be met.
Description
technical field [0001] The invention relates to the technical field of locomotive vehicle maintenance, in particular to a shaft-mounted brake disc wear detection ruler and a detection method. Background technique [0002] The existing shaft-mounted brake disc wear detection ruler uses the wear limit step of the shaft-mounted brake disc as the supporting plane. Since there is no wear limit step on the inner side of some shaft-mounted brake discs, there is no wear limit step on the inner side when using the existing wear detection ruler. When the shaft-mounted brake disc is installed, the reference cannot be positioned, and it cannot provide effective support for the subsequent judgment of the shaft-mounted brake disc scrapping and process flow judgment, resulting in the scrapping or rework of the shaft-mounted brake disc due to inaccurate data. Contents of the invention [0003] In order to solve the shortcomings and deficiencies of the prior art, a shaft-mounted brake disc...
