[0047] Please refer to Figures 1 to 5 As shown, the first embodiment of the present invention is: a rapid detection device for the mounting groove of the surface encoder of the automobile motor shaft, comprising:

[0048] The base 1 is provided with a guide support 2 and a fixed tailstock 3 and a movable seat 4 located on opposite sides of the guide support 2;

[0052] The movable base 4 includes a slider 43 and a structural plate 44. The slider 43 is slidably connected to the base 1. The second ejector pin 41 is mounted on the slider 43. The structural plate 44 is mounted on the slider 43. The measuring tool 42 is mounted on the structural plate 44. The number of guide supports 2 is greater than or equal to two. The base 1 is provided with a motor shaft support block 5 located between two adjacent guide supports 2. The motor shaft support block 5 is provided with a support groove 51 having a V-shaped cross-section.

The guide head 21, the first ejector pin 31, the second ejector pin 41, and the measuring pin of the measuring tool 42 are located in the same vertical plane, with the first ejector pin 31 and the second ejector pin 41 at the same horizontal height.

The blade anvil's width is set according to the keyway being measured, and the base of the blade anvil remains horizontal. The width of the guide head 21 matches the width of the keyway in the middle of the motor shaft. When the guide head 21 engages the keyway in the middle of the motor shaft, the motor shaft assumes a horizontal, straight position, with the encoder mounting slot at the right end of the motor shaft positioned directly above. During measurement, the right structural plate 44 is removed, the keyway in the middle of the motor shaft is aligned with the guide support 2, and the motor shaft is positioned on the V-shaped motor shaft support block 5. The structural plate 44 is then pushed from right to left, causing the second ejector pin 41 to enter the right center hole of the motor shaft and the blade anvil to slide into the encoder mounting slot. The structural plate 44 is then pushed rightward until the left center hole of the motor shaft engages the first ejector pin 31 on the tailstock. The motor shaft is then released from the V-shaped motor shaft support block 5. The motor shaft, under the combined action of the left and right ejectors and the guide head 21, assumes a horizontal, straight position. The micrometer reading is then observed to quickly determine if the mounting slot depth and width meet the requirements.

[0054] In summary, the present invention provides a rapid detection device for the mounting groove of an automobile motor shaft surface encoder. The guide support utilizes a guide head to position the motor shaft. The movable base positions one end of the motor shaft via a second thimble, then pushes the motor shaft so that the other end rests against the first thimble of the fixed tailstock to complete the positioning. Finally, a measuring tool is used to detect the depth and width of the mounting groove of the motor shaft surface encoder. The present invention provides a rapid detection device for the mounting groove of an automobile motor shaft surface encoder. The device has a compact and reasonable structure, low manufacturing cost, is simple and quick to use, and provides intuitive and reliable detection. It can be flexibly configured on a production line, effectively improving detection efficiency and accuracy, and facilitating quality control of the motor shaft.
