Description

Technical Field

[0001] The utility model relates to a special fixing tool for aligning the center of a coupling to a wheel. Background Art

[0002] At present, the coupling uses a magnetic seat for aligning the wheel center. The magnetic seat is magnetically attracted to the coupling. Due to the uneven surface of the coupling, the magnetic seat is easy to loosen during the rotation process after being magnetically attracted, resulting in inaccurate measurement data. The magnetic seat needs to be adjusted frequently and the readings need to be repeated, which greatly reduces the maintenance efficiency and affects the maintenance quality. The seat arm is spliced ​​in two sections, and the restraining part is easy to loosen, affecting the accuracy. Utility Model Content

[0017] Reference Figure 1-Figure 5 A special fixing tool for aligning the center of a coupling to a wheel, comprising a crank arm 3, a sliding hole 13 being provided on the crank arm, the crank arm being slidably connected to a sliding frame 4 through the sliding hole, a limit bolt 12 passing through the sliding hole and being threadedly connected to the sliding frame, an axial surface hole 6 and a radial surface hole 7 being provided on the crank arm, both the axial surface hole and the radial surface hole being circular hole structures, an axial surface locking bolt 10 being threadedly connected to the axial surface hole, and a radial surface locking bolt 9 being threadedly connected to the radial surface hole.

[0018] The coupling is a special fixing tool for aligning the wheel center, and the crank arm is an L-shaped crank arm.

[0019] The coupling is a special fixing tool for aligning the wheel center, and a U-shaped notch 11 is provided on the sliding frame.

[0020] Working principle: Refer to Figure 6 When in use, slide the sliding frame to make it fall on the coupling 8 flange, and connect and fix the sliding frame and the coupling flange with the fixing bolts to achieve the fixation of the device. After the axial gauge is passed through the axial gauge hole, the test end is pressed against the outer ring surface of the coupling flange, and then locked by the axial gauge locking bolt. After the radial gauge is passed through the radial gauge hole, the test end is pressed against the end face of the coupling flange and then locked by the radial gauge locking bolt. Two special tools are fixed on both sides for measurement, and the special crank arm and the wheel flange are imprisoned by the fixing bolts. The two-section splicing structure is cancelled, and the white gauge is directly fixed to the crank arm. During the rotation process, it is both stable and accurate, and will not loosen, which can improve maintenance efficiency and reduce labor costs.
