[0058] The conical surface rapid measurement assembly 5 includes an angle measurement plate 501 provided on the side of the measurement plate support base 401. A rotating connection chamber 502 is provided on the side of the measurement plate support base 401. A side opening 503 is formed in the rotating connection chamber 502. The bottom end of the angle measurement plate 501 is inserted into the side opening 503. A measurement rotating rod 504 is rotatably inserted in the side opening 503. Both ends of the measurement rotating rod 504 rotatably penetrate through the rotating connection chamber 502.

[0059] The measurement rotating rod 504 is fixedly connected to the angle measurement plate 501. A side driving chamber 505 is provided on the side of the rotating connection chamber 502. A large transmission gear disc 506 is rotatably provided in the side driving chamber 505. The end of the measurement rotating rod 504 rotatably penetrates through the side driving chamber 505 and is fixedly connected to the central axis of the large transmission gear disc 506. A small transmission gear disc 507 is rotatably provided on the side of the large transmission gear disc 506. The central axis of the small transmission gear disc 507 is rotatably connected to the inner wall of the side driving chamber 505.

[0060] The small transmission gear disc 507 is in meshing transmission with the large transmission gear disc 506. A rotating grip 508 is provided on the outside of the side driving chamber 505. The end of the rotating grip 508 is inserted into the side driving chamber 505 and is fixedly connected to the central axis of the small transmission gear disc 507.

The precision angle scale 510 is connected to the measurement plate support base 401 through a provided base.

[0061] Compared with the original solution, this solution has a conical fixing component 2, and the workpiece to be measured is displaced during the measurement process; it has a direct reading component - the angle indicating needle 509, saving the trouble of manual calculation by the measurement personnel; it has an angle fine-tuning component - the side driving chamber 505, which can better adjust the measurement plate and improve the measurement accuracy.

[0062] Embodiment 2: The difference between this embodiment and Embodiment 1 is that, among them, a limiting groove is formed in the bottom wall of the top driving groove 402. The bottom ends of the driving nut 404 and the support sliding sleeve 405 are slidably provided in the limiting groove through provided limiting blocks.

[0063] When the driving screw 403 rotates, it can drive the driving nut 404 sleeved on the driving screw 403 to stably move in the horizontal direction.

[0064] Embodiment 3: The difference between this embodiment and Embodiment 1 is that the measuring plate support seat 401 and the angle measuring plate 501 are both arranged in an inclined shape.

[0065] The angle measuring plate 501 on the measuring plate support seat 401 fits better with the bottom of the taper part main body 3.

[0066] Embodiment 4: The difference between this embodiment and Embodiment 1 is that the diameter of the small transmission gear disc 507 is much smaller than the diameter of the large transmission gear disc 506.

[0067] The rotation of the measuring rotating rod 504 by the user becomes slower, so that the angle adjustment of the angle measuring plate 501 connected to the measuring rotating rod 504 is more precise.

[0068] In this embodiment, for the existing part taper angle measuring tooling, most still calculate the taper of the tapered part by manually measuring multiple times and summarizing the measured data. At this time, the measuring method has low efficiency, low precision, and poor fixing effect on the tapered part. It is easy to have large measurement errors during measurement, which is not convenient for users to measure and use.

[0069] In summary, during specific implementation, when the user needs to measure the taper angle of the taper part main body 3, the user first needs to insert the taper part main body 3 into the side fixing groove 202 in the part fixing component 2. By rotating the abutting screw 203, the abutting screw 203 is pushed to make the fixed abutting plate 204 abut and fix the end of the taper part main body 3, so that the taper part main body 3 is fixed on the part fixing seat 201.

[0070] At this time, the angle displayed by the angle indicating needle 509 in the taper rapid measurement component 5 on the measuring plate support seat 401 on the precision angle disc 510 is recorded by the user. Then, by rotating the driving screw 403, the driving screw 403 pushes the measuring plate support seat 401 to move towards the bottom side of the taper part main body 3 through the driving nut 404, so that the bottom end of the angle measuring plate 501 arranged on the measuring plate support seat 401 abuts against the bottom of the taper part main body 3.

[0071] Finally, by rotating the rotating grip 508, the rotating grip 508 drives the large transmission gear disk 506 to rotate through the small transmission gear disk 507. The large transmission gear disk 506 drives the angle measurement plate 501 to rotate through the measurement rotating rod 504, so that the upper surface of the angle measurement plate 501 can completely fit with the bottom side surface of the taper part main body 3. Furthermore, during the rotation of the measurement rotating rod 504, the angle indicating needle 509 provided at the end of the measurement rotating rod 504 will also rotate synchronously, causing the angle position indicated by the angle indicating needle 509 on the precision angle scale 510 to change.

[0072] Based on the change in the angle on the precision angle scale 510 and the previously recorded initial angle, the user can quickly and conveniently obtain the angle of the side taper surface of the taper part main body 3. Moreover, this device can adapt to the measurement of the taper angles of various different parts, has a wider application range, faster measurement effect, and relatively higher measurement accuracy. By firmly fixing the taper part main body 3 through the part fixing component 2, the error generated during the measurement of the taper part main body 3 can be greatly reduced, making it more convenient for the user to measure and use.

[0073] Compared with the prior art, the present utility model provides a measuring tool for measuring the taper angle of a part, having the following beneficial effects:

[0074] In the present utility model, a measurement driving component 4 is provided on the measurement support base plate 1, and a taper surface rapid measurement component 5 is provided on the measurement driving component. Among them, the angle measurement plate 501 in the taper surface rapid measurement component 5 can be pushed by the measurement plate support seat 401, so that the end of the angle measurement plate 501 abuts against the side taper surface of the taper part main body 3. By rotating the measurement rotating rod 504, the surface of the angle measurement plate 501 can be closely attached to the side taper surface of the taper part main body 3. Furthermore, by comparing the angle change shown by the angle indicating needle 509 provided at the end of the measurement rotating rod 504 on the precision angle scale 510 with the initial angle, the angle of the side taper surface of the taper part main body 3 can be quickly and conveniently obtained. Moreover, this device can adapt to the measurement of the taper angles of various different parts, has a wider application range, faster measurement effect, and relatively higher measurement accuracy. By firmly fixing the taper part main body through the part fixing component, the error generated during the measurement of the taper part main body can be greatly reduced, making it more convenient for the user to measure and use.

[0075] In this specification, each embodiment is described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. For the same or similar parts among the embodiments, reference can be made to each other.
