[0022] Reference Figures 1 to 7 This application provides a comprehensive inspection fixture for an electric output shaft, comprising: a base 100 with a fixed seat 110; a base plate 200 disposed on one side of the fixed seat 110, the base plate 200 being slidable relative to the fixed seat 110, the base plate 200 having a positioning seat 210 for placing an electric output shaft 400, the positioning seat 210 having a through hole 220, a first shaft segment of the electric output shaft 400 being embedded in the through hole 220, the positioning seat 210 having a first clearance hole 230 and a second clearance hole 240; and a measuring mechanism disposed on the fixed seat 110, the measuring mechanism including an outer diameter measuring component and a length measuring component, the outer diameter measuring component including a first outer diameter measuring part. The first outer diameter measuring unit 310 and the second outer diameter measuring unit 320 are adapted to the first clearance hole 230. The first outer diameter measuring unit 310 is used to measure the first shaft diameter D1 of the electric output shaft 400, and the second outer diameter measuring unit 320 is used to measure the second shaft diameter D2 of the electric output shaft 400. The length measuring assembly includes a first length measuring unit 330 and a second length measuring unit 340. The first length measuring unit 330 is adapted to the second clearance hole 240. The first length measuring unit 330 is used to measure the first length L1 of the electric output shaft 400, and the second length measuring unit 340 is used to measure the second length L2 of the electric output shaft 400.

[0023] Before measuring the parts, the outer diameter measuring assembly and length measuring assembly are calibrated using standard parts. Then, the first shaft segment of the electric output shaft 400 is inserted into the through hole 220 of the positioning seat 210, so that the electric output shaft 400 is placed vertically on the positioning seat 210. The base plate 200 slides relative to the fixed seat 110 and reaches the defined position. At this time, the first shaft diameter D1 and the second shaft diameter D2 of the electric output shaft 400 are measured by the first outer diameter measuring part 310 and the second outer diameter measuring part 320, respectively, and the first length L1 and the second length L2 of the electric output shaft 400 are measured by the first length measuring part 330 and the second length measuring part 340, respectively. The comprehensive inspection fixture for the electric output shaft 400 described in this application embodiment can measure the first shaft diameter D1 and the second shaft diameter D2, as well as the first length L1 and the second length L2 of the electric output shaft 400 at one time, without the need for manual measurement, reducing labor intensity, improving work efficiency, and improving measurement accuracy.

[0024] Reference Figure 1 and Figure 2 The base 100 is equipped with a translation component 130, and the substrate 200 is disposed on the translation component 130. The translation component 130 drives the substrate 200 to slide relative to the fixed seat 110, resulting in a simple structure and easy operation. Further, the translation component 130 includes a slide rail, a slider, and a drive unit. The slide rail is disposed on the base 100, the slider is disposed on the substrate 200, and the slider is connected to the slide rail. The drive unit is connected to the substrate 200. Specifically, the drive unit includes a rotating shaft, a rocker arm, and a connecting rod. The base 100 is provided with a support seat, the rotating shaft is rotatably disposed on the support seat, one end of the rocker arm is fixedly connected to the rotating shaft, one end of the connecting rod is connected to the other end of the rocker arm via a pin, and the other end of the connecting rod is connected to the substrate 200. The rotating shaft is provided with a handle. By operating the handle to rotate the rotating shaft, the rocker arm drives the connecting rod to move, causing the substrate 200 to slide along the slide rail, resulting in a simple structure and easy operation. Of course, the drive unit can also be directly configured as a cylinder, a lead screw and nut, or a gear and rack; this application does not limit this.

[0025] It should be noted that the translation component 130 can also be connected to the fixed base 110. The translation component 130 drives the fixed base 110 to move, so that the measuring mechanism is close to the electric output shaft 400 and performs measurement.

[0026] Furthermore, the base 100 is disposed on the placement seat 140, which is used to place standard parts, making operation simpler and improving work efficiency.

[0027] Reference Figure 4The first outer diameter measuring unit 310 includes a first measuring unit 311, a second measuring unit 312, and a first measuring gauge 313. The first measuring unit 311 and the second measuring unit 312 cooperate to measure the first shaft diameter D1 of the electric output shaft 400. The first measuring unit 311 is provided with a first measuring rod 314, and the first measuring gauge 313 is disposed in the second measuring unit 312. The head of the first measuring gauge 313 abuts against the end of the first measuring rod 314. Specifically, the first measuring unit 311 and the second measuring unit 312 abut against the electric output shaft 400 through a first clearance hole 230 to realize the measurement of the first shaft diameter D1 of the electric output shaft 400. The structure is simple and the operation is convenient.

[0028] Reference Figure 5 Specifically, the first measuring unit 311 includes a mounting block 315, a bracket 316, and a first abutment block 317. The mounting block 315 is disposed on the fixed base 110, and the bracket 316 is disposed on the side of the mounting block 315 away from the fixed base 110. The two ends of the mounting block 315 and the bracket 316 are connected by a first spring piece 318 and a second spring piece 319, respectively. The first spring piece 318 and the second spring piece 319 are used to support and reset the bracket 316, respectively. The first abutment block 317 is disposed on the bracket 316, and the first measuring rod 314 is disposed on the first abutment block 317. The structure of the second measuring unit 312 is the same as that of the first measuring unit 311, and the first measuring gauge 313 is disposed on the first abutment block 317 of the second measuring unit 312. The first contact blocks 317 of the first measuring unit 311 and the second measuring unit 312 respectively contact the electric output shaft 400. At this time, the displacement change of the first measuring rod 314 is transmitted to the meter head of the first measuring meter 313, thereby realizing the measurement of the first shaft diameter D1 of the electric output shaft 400.

[0029] It is conceivable that the first measuring unit 311 and the second measuring unit 312 are adjustablely mounted on the fixed base 110, allowing them to move closer or further apart, thus adjusting the distance between them. This adapts to electric output shafts 400 with different shaft diameters, expanding the applicability. The fixed base 110 is provided with a sliding groove containing a slotted hole. The mounting block 315 is embedded in the sliding groove and connected to the mounting block 315 via a locking element passing through the slotted hole. This structure enables rapid positioning of the mounting block 315, improving installation efficiency.

[0030] In this embodiment, the structure of the second outer diameter measuring unit 320 is the same as that of the first outer diameter measuring unit 310. By measuring the second shaft diameter D2 of the electric output shaft 400 using the second outer diameter measuring unit 320, the accuracy of the measurement can be improved.

[0031] Reference Figure 6 The first length measuring unit 330 includes a third measuring unit 331, a fourth measuring unit 332, and a second measuring gauge 333. The third measuring unit 331 and the fourth measuring unit 332 cooperate to measure the first length L1 of the electric output shaft 400. The third measuring unit 331 is provided with a second measuring rod 334, and the second measuring gauge 333 is provided on the fourth measuring unit 332. The head of the second measuring gauge 333 abuts against the second measuring rod 334. The third measuring unit 331 is provided with a second abutment block 335, and the fourth measuring unit 332 is provided with a third abutment block 336. Specifically, after the substrate 200 slides relative to the fixed base 110 and reaches the defined position, the second abutment block 335 enters the positioning sleeve along the second clearance hole 240 and abuts against the shaft end face of the electric output shaft 400, and the third abutment block 336 abuts against the other end face of the electric conveying shaft. The displacement change of the second measuring rod 334 is displayed by the second measuring gauge 333, thereby realizing the measurement of the first length L1 of the electric output shaft 400. The structure is simple and the operation is convenient.

[0032] Reference Figure 7 The second length measuring unit 340 includes a fifth measuring unit 341 and a third measuring gauge 342. The fifth measuring unit 341 is used to measure the second length L2 of the electric output shaft 400. The fifth measuring unit 341 is provided with a measuring block 343, and the third measuring gauge 342 is provided on the fixed base 110. The head of the third measuring gauge 342 abuts against the measuring block 343. The fifth measuring unit 341 is also provided with a fourth abutment block 344. After the base plate 200 slides relative to the fixed base 110 and reaches a predetermined position, the fourth abutment block 344 abuts against the end face of the electric conveyor shaft, and the displacement change of the measuring block 343 is displayed by the third measuring gauge 342, thereby realizing the measurement of the second length L2 of the electric output shaft 400. The structure is simple and the operation is convenient.

[0033] It should be noted that the structures of the third measuring unit 331, the fourth measuring unit 332 and the fifth measuring unit 341 are basically the same as the structure of the first measuring unit 311, therefore, this application will not elaborate on them further.

[0034] It should also be noted that the third measuring unit 331, the fourth measuring unit 332 and the fifth measuring unit 341 can all be adjusted and set on the fixed base 110, so as to be able to adapt to electric output shafts 400 of different lengths and expand the scope of application.

[0035] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
