Description

Technical Field

[0001] The present invention relates to the technical field of motor detection, and specifically to a FG signal detection control system and its tooling. Background Art

[0002] In the field of motor production and manufacturing, motor quality inspection is a key link to ensure product quality. Currently, there are quality problems such as motors not rotating during the motor production process, and existing detection technologies and tooling have many deficiencies: 1. Poor detection accuracy: When the existing motor detection system judges the operating state of the motor, the detection method is relatively single. Most only judge based on the frequency range of motor operation, without fully considering complex situations such as frequency fluctuations that may occur during motor operation. This simple judgment method is prone to misjudgment and cannot accurately identify whether the motor has a non-rotation fault, allowing some motors with potential problems to enter the market, affecting the overall product quality and user experience.

[0003] 2. Poor fixture versatility: Traditional fixtures for fixing motors usually have fixed sizes and can only fit motors of specific specifications. Since motors come in various sizes in actual production, when it is necessary to detect motors of different sizes, the fixtures have to be frequently replaced. This not only consumes a large amount of time and labor costs but also reduces the production efficiency of motor detection and affects the production progress.

[0004] 3. Inconvenient operation and insufficient stability: When the existing tooling adjusts and fixes the motor, the operation process is cumbersome, relying on manual adjustment, and it is difficult to ensure the accuracy and consistency of each adjustment. At the same time, manual operation is prone to introducing mechanical errors, resulting in the motor being not firmly fixed during the detection process, affecting the reliability of the detection results. Moreover, the structural design of the tooling lacks stability, and during long-term use, problems such as component loosening and deformation are likely to occur, further reducing the detection accuracy. Summary of the Invention

During the motor positioning process, it can effectively prevent the adjustment component from loosening, improve the stability of the adjustment component during use, and ensure that the motor is firmly fixed during the detection process. At the same time, after the detection is completed, the electric control makes the pawl disengage from the ratchet, which is convenient for the staff to quickly disassemble the motor, and the operation is simple and convenient. In addition, the bearing on the surface of the transmission rod limits the position of the transmission rod to prevent its position from shifting during rotation; the limit sleeve and the limit rod cooperate to limit the toothed plate, enhancing the stability of the toothed plate during use; the positioning block limits the pawl to prevent the pawl from shifting in position. The combined action of these structural designs improves the overall operation convenience and stability of the tooling. Description of the Drawings

[0035] Working principle: When in use, the staff member fits the inner side of the motor to the outer side of the arc-shaped plate 6, and then pulls the toothed plate 206 forward. When the toothed plate 206 moves forward, it drives the gear 204 to rotate clockwise. When the gear 204 rotates clockwise, it drives the transmission rod 201 to rotate. When the transmission rod 201 rotates clockwise, it drives the circular plate 202 and the ratchet wheel 205 to rotate clockwise. When the circular plate 202 rotates clockwise, it drives the four pulleys 203 to rotate. When the four pulleys 203 rotate, they squeeze the four inclined blocks 7. After being squeezed, the four inclined blocks 7 drive the four arc-shaped plates 6 to move. When the four arc-shaped plates 6 move, they drive the four sliding sleeves 4 to move. When the four sliding sleeves 4 move, they stretch the four tension springs 5. When the outer sides of the four arc-shaped plates 6 contact the inner side of the motor, the motor can be positioned. At the same time, when the ratchet wheel 205 rotates clockwise, the pawl 209 can be used to limit the reverse rotation of the ratchet wheel 205, thereby improving the stability of the use of the adjustment assembly 2. After the positioning is completed, the staff member inserts the slider 11 into the inner cavity of the chute 10, so that the matching filling plate 12 is connected to the arc-shaped plate 6. After installation and connection, the filling plate 12 and the arc-shaped plate 6 form a circular frame to fix the motor. After the detection is completed, the staff member uses an external power source to start the electric telescopic rod 207. The telescopic end of the electric telescopic rod 207 drives the positioning frame 208 to move, so that the pawl 209 is disengaged from the ratchet wheel 205. Then, the toothed plate 206 is pushed backward. When the toothed plate 206 rotates, it drives the gear 204 to rotate counterclockwise. When the gear 204 rotates counterclockwise, it drives the transmission rod 201 and the circular plate 202 to rotate counterclockwise. At this time, the reaction force of the tension spring 5 is used to drive the arc-shaped plate 6 and the inclined block 7 to move, and the motor can be disassembled.
