Abstract
Description
Technical Field
[0001] This utility model relates to the field of three-coordinate auxiliary measurement technology for motor rotors, specifically a three-coordinate auxiliary measurement fixture for motor rotors. Background Technology
[0002] The coordinate measuring machine (CMM) fixture for motor rotors is a specialized fixture used to accurately position and fix rotors on a CMM to ensure measurement accuracy and repeatability. The fixture's datum must be aligned with the rotor's design datum (such as the shaft center, end face, or keyway) to avoid datum conversion errors. Typically, CMM fixtures for motor rotors use V-blocks, centers, or expansion sleeves to ensure the rotor axis is consistent with the CMM coordinate system. However, different types of motor rotors are encountered during measurement. Due to the varying lengths of motor rotors, it is difficult to quickly determine the rotor's end face, thus hindering the rapid determination of the rotor's position, which presents certain shortcomings. Therefore, we propose a CMM fixture for motor rotors. Utility Model Content
[0003] The present invention aims to solve the problems existing in the prior art or related technologies.
[0004] Therefore, the technical solution adopted by this utility model is as follows: a three-coordinate auxiliary measuring fixture for a motor rotor, comprising a base plate, a first support assembly, a second support assembly, a positioning assembly, a vertical plate, and a pin. The top of the base plate is provided with a sliding groove. The first support assembly includes a support seat slidably connected to the sliding groove, a V-groove opened at the top of the support seat, and a first fastening knob threadedly connected to the support seat. The second support assembly is fixedly disposed on the base plate, and the second support assembly has the same structure as the first support assembly. The positioning assembly includes a sliding seat slidably connected to the sliding groove, a positioning plate hinged to the top of the sliding seat, a slot opened on the positioning plate, and a second fastening knob threadedly connected to the positioning plate. The vertical plate is fixedly disposed at the top of the sliding seat, and the pin passes through the vertical plate and the positioning plate.
[0005] Preferably, mounting holes are provided at the corners of the base plate, and scale lines are provided on the right side of the base plate.

It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.
[0024] The following describes some embodiments of this utility model with reference to the accompanying drawings, providing a motor rotor coordinate measuring auxiliary tooling.
[0025] Example 1:
[0026] Reference Figure 1-4 This is the first embodiment of the present invention. This embodiment provides a three-coordinate auxiliary measuring fixture for a motor rotor, including a base plate 100, a first support component 200, a second support component 300, a positioning component 400, a vertical plate 500, and a pin 600.
[0027] Specifically, the top of the base plate 100 is provided with a sliding groove 102, and mounting holes 101 are provided at the corners of the base plate 100. A scale line 103 is provided on the right side of the base plate 100. In use, the sliding groove 102 allows the first support component 200 and the second support component 300 to be moved so that the position of the motor rotor can be adjusted by the first support component 200 and the second support component 300. The mounting holes 101 facilitate bolt fixing of the base plate 100, and the scale line 103 allows for precise adjustment of the position of the positioning component 400 for use.
[0028] Specifically, the first support assembly 200 includes a support base 201 slidably connected to the slide groove 102, a V-groove 203 formed at the top of the support base 201, and a first fastening knob 204 threadedly connected to the support base 201. A first slider 202 is provided at the bottom of the support base 201. The first slider 202 is slidably connected to the base plate 100 through the slide groove 102. In use, motor rotors of different sizes can be placed on the support base 201 through the V-groove 203, and the first fastening knob 204 can be rotated to abut against the base plate 100 to adjust the position of the first support assembly 200. Then, the support base 201 can slide on the base plate 100 through the first slider 202 to adjust the position of the motor rotor.
[0029] Specifically, the second support component 300 is fixedly mounted on the base plate 100. The second support component 300 has the same structure as the first support component 200. In use, the second support component 300 and the first support component 200 can support motor rotors of different sizes to improve stability.
[0030] Specifically, the positioning component 400 includes a sliding seat 401 slidably connected to the slide groove 102, a positioning plate 403 hinged to the top of the sliding seat 401, a slot 4031 formed on the positioning plate 403, and a second fastening knob 404 threadedly connected to the positioning plate 403. The second fastening knob 404 has the same structure as the first fastening knob 204, and both the second fastening knob 404 and the first fastening knob 204 are T-shaped studs. A second slider 402 is provided at the bottom of the sliding seat 401. The second slider 402 has the same structure as the first slider 202. In use, the sliding seat 401 can slide on the base plate 100 by means of the second slider 402. The sliding seat 401 can be moved by loosening the second fastening knob 404 in order to adjust the position of the positioning component 400. It is suitable for multiple coordinate measuring machines and has a wide range of applications. Then, by rotating the positioning plate 403 to the vertical direction, the motor rotor can be blocked in order to quickly determine the end face of the motor rotor.
[0031] Specifically, the vertical plate 500 is fixedly installed at the top of the sliding seat 401. The vertical plate 500 has a through hole 501 for inserting the pin 600. The through hole 501 is a round hole. In use, the vertical plate 500 can support and restrain the pin 600 so that the positioning plate 403 can be fixed by the pin 600.
[0032] Specifically, the pin 600 is inserted into the vertical plate 500 and the positioning plate 403. The pin 600 has a rounded corner 601 and is T-shaped. In use, the pin 600 can pass through the vertical plate 500 and engage with the slot 4031 of the positioning plate 403. After engagement, the positioning plate 403 can be fixed so that the position of the motor rotor can be determined by the positioning plate 403.
[0033] The working principle and usage process of this utility model are as follows: First, loosen the second fastening knob 404. After loosening, move the sliding seat 401 along the slide groove 102, referring to the scale line 103. After moving to the appropriate position, tighten the second fastening knob 404 to adjust the position of the precise positioning component 400. Then, rotate the positioning plate 403 to the vertical direction. Next, align the pin 600 with the through hole 501 of the vertical plate 500 and insert it until the pin 600 engages with the slot 4031, thus fixing the positioning plate 403. After fixing, place the outer ring of the motor rotor on the first support component 200 and the second support component 300. After placement, loosen the first fastening knob 204. After loosening, move the first support component 200 and the second support component 300. Moving the first support component 200 and the second support component 300 will drive the motor rotor until the rotor abuts against the positioning plate 403, thus determining the position of the motor rotor.
