DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0023] like Figure 1-3 As shown, a measuring device for the 1 / 2 span value of a half-punch gear plate of an angle adjuster comprises a driving device 1, a guiding shaft 3, a supporting seat 2, a contact rod 7, a spring 10 and a micrometer 11; the guiding shaft 3 is used for installing the gear plate 4 to be measured, and the driving device 1 is used to drive the guiding shaft 3 to rotate; the contact rod 7 is movably mounted on the supporting seat 2, and is provided with a contact head 6 for contacting the inner teeth of the gear plate 4 to be measured; the contact rod 7 is located between the guiding shaft 3 and the micrometer 11; the spring 10 abuts between the contact rod 7 and the supporting seat 2, and is used to provide an elastic force that causes the contact rod 7 to move toward the measuring rod direction close to the micrometer 11.

[0024] When in use, the contact rod 7 can be moved away from the micrometer 11, and then the gear plate 4 to be measured is installed on the guide shaft 3, and then the contact rod 7 is released. At this time, the contact rod 7 moves toward the measuring rod direction close to the micrometer 11 under the elastic force of the spring 10, and the contact head 6 of the contact rod 7 contacts the inner teeth of the gear plate 4 to be measured, and the contact rod 7 contacts the measuring rod of the micrometer 11. The micrometer 11 is used for measurement. By reading the value of the micrometer 11 and adding the value to the reference value, the MRK value of the tooth can be obtained, and then the contact rod 7 is moved away from the micrometer 11. The contact rod 7 is then released. At this time, the contact rod 7 moves toward the measuring rod direction close to the micrometer 11 under the elastic force of the spring 10. The contact head 6 of the contact rod 7 contacts the next inner tooth of the gear plate 4 to be measured, and the contact rod 7 contacts the measuring rod of the micrometer 11. By reading the value of the micrometer 11, the MRK value of the second inner tooth can be obtained. Then, the above method is repeated to complete the MRK value measurement of each inner tooth of the gear plate 4 to be measured, thereby completing the measurement. The utility model provides a device for measuring the 1 / 2 span rod value of a half-punch gear plate of an angle adjuster, which adopts a combination of a driving device 1, a guide shaft 3, a support seat 2, a contact rod 7, a spring 10 and a micrometer 11, and utilizes the contact head 6 of the contact rod 7 to contact the inner teeth of the gear plate 4 to be measured, and the contact rod 7 contacts the measuring rod of the micrometer 11, and the MRK value of the gear plate 4 to be measured can be measured by the micrometer, and after the contact rod 7 is moved away from the previous inner tooth, the driving device 1 rotates the guide shaft 3 to connect the MRK value of the gear plate 4 to be measured. The gear plate 4 to be tested is moved to the next internal tooth, and then reset by the contact rod 7, so that the contact rod 7 contacts the next internal tooth again. By reading the reading on the micrometer, the MRK value of another internal tooth can be obtained, which can make the MRK measurement time of a 34-tooth half-punch gear plate 4 to be tested about 3 minutes, making the measurement of the 1 / 2 span rod value of the half-punch gear plate 4 to be tested by the angle adjuster quick and time-saving, which can improve the measurement efficiency, and the structure is simple and easy to manufacture, which can reduce costs and reduce human errors, so that the measurement accuracy can reach 0.01mm, which can improve the measurement accuracy.

[0025] The measuring device for the 1 / 2 span value of the half-punch gear plate of the angle adjuster also includes a clamping device 5, which is used to press the gear plate 4 to be measured on the guide shaft 3 so that the gear plate 4 to be measured rotates synchronously with the guide shaft 3. By adopting the clamping device 5, the stability of the gear plate 4 to be measured installed on the guide shaft 3 can be improved, ensuring that the gear plate 4 to be measured rotates synchronously with the guide shaft 3.

[0026] In this embodiment, the clamping device 5 includes a base, a handle installed on the base, and a clamping block connected to the handle. When in use, the gear plate 4 to be tested can be pressed tightly onto the guide shaft 3 by pulling the handle and utilizing the clamping block on the handle.

[0027] Of course, in addition to this, the clamping device 5 can also adopt a clamping rod, a gravity block, etc. hinged on the support seat 9, as long as it can be used to press the gear plate 4 to be tested against the guide shaft 3 so that the gear plate 4 to be tested can rotate synchronously with the guide shaft 3.

[0028] The measuring device for the 1 / 2 span value of the half-punch gear plate of the angle adjuster also includes a support seat 9, and the guide shaft 3 is rotatably mounted on the support seat 9.

[0029] The driving device 1 is a motor, and the guide shaft 3 is connected to the output shaft of the motor. By using a motor as the driving device 1, the guide shaft 3 can be driven to rotate and the installation is convenient.

[0030] The guiding shaft 3 is provided with a center groove 20, which is in a truncated cone shape and is matched with the boss of the gear plate 4 to be measured. When in use, the boss of the gear plate 4 to be measured is embedded in the center groove 20 of the guiding shaft 3, and the boss on the gear plate 4 to be measured can be automatically guided by the taper of the center groove 20 of the guiding shaft 3, thereby realizing automatic guidance of the gear plate 4 to be measured, so as to further improve the measurement accuracy.

[0031] The support base 2 is provided with a transverse groove 16, and the contact rod 7 is movably installed in the transverse groove 16. By adopting the above structure, the installation of the contact rod 7 can be facilitated.

[0032] The support seat 2 is provided with a lower groove 17 located below the transverse groove 16 and connected to the transverse groove 16, and the contact rod 7 is provided with a supporting portion 19, the lower end of which extends into the lower groove 17. One end of the spring 10 abuts against the groove wall of the lower groove 17, and the other end abuts against the lower end of the supporting portion 19. By adopting the above structure, the installation of the spring 10 can be facilitated.

[0033] The support seat 2 is provided with a limiting groove 18 located above the transverse groove 16 and connected to the transverse groove 16. The contact rod 7 is connected with a lever 8, and the lever 8 is inserted into the limiting groove 18. When in use, by shifting the lever 8 away from the dial gauge 11, the contact rod 7 can be moved away from the dial gauge 11, and the contact head 6 of the contact rod 7 is separated from the inner teeth of the gear plate 4 to be measured, so as to facilitate operation. By releasing the lever 8, the contact rod 7 is reset under the elastic force of the spring 10, so that the contact head 6 of the contact rod 7 contacts the inner teeth of the gear plate 4 to be measured, and the contact rod 7 contacts the dial gauge 11. The moving stroke of the lever 8 can be limited by the limiting groove 18, so as to limit the moving stroke of the contact rod 7.

[0034] As a further preferred embodiment of the present invention, when the lever 8 is moved away from the micrometer 11, the lever 8 also contacts the motor switch, so that the motor works to drive the gear plate 4 to be tested to rotate a pitch angle, so as to improve the convenience of use.

[0035] The measuring device for the 1 / 2 span value of the half-punch gear plate of the angle adjuster also includes a support seat 12, and the micrometer 11 is arranged on the support seat 12. Specifically, the measuring device for the 1 / 2 span value of the half-punch gear plate of the angle adjuster also includes a bottom seat 13, and the support seat 2, the support seat 9 and the support seat 12 are all fixed on the bottom seat 13.

[0036] Preferably, the measuring device for the 1 / 2 span rod value of the half-punch gear plate of the angle adjuster also includes a correction block 15, which is used to be installed on the guide shaft 3, and is provided with a correction platform for being embedded in the center groove 20. The correction block 15 is provided with a U-shaped groove, so that zero correction can be performed through the correction block 15 to further improve the measurement accuracy.

[0037] The actual working process of the utility model when in use is as follows: open the clamping block, turn the lever 8, align the boss of the correction block 15 with the center groove 20 of the guide shaft 3, and at the same time, the U-shaped groove of the correction block 15 matches the contact head 6 on the contact rod 7, and both sides of the U-shaped groove of the correction block 15 do not contact the contact head 6 on the contact rod 7; pull the handle to make the clamping block clamp the correction block 15, release the lever 8 to reset, return the dial indicator 11 to zero, complete the zero correction, and then open the clamping block, turn the lever 8, and take away the correction block 15.

[0038] Then open the clamping block, turn the lever 8, insert the boss of the gear plate 4 to be tested into the center groove 20 of the guiding shaft 3, and the gear plate 4 to be tested is automatically aligned by the guiding shaft 3 and is concentric with the guiding shaft 3; pull the handle to make the clamping block press the gear plate 4 to be tested, release the lever 8 to reset it, read the value of the micrometer 11, add the value to the reference value, and you can get the MRK value.

[0039] Start the motor and move the lever 8. The motor drives the guide shaft 3 to rotate, and indirectly drives the gear plate 4 to be tested to rotate a pitch angle. Release the lever 8, the contact rod 7 is reset, and the value of the micrometer 11 is read to obtain the MRK value of the second tooth shape.

[0040] By analogy, each time the lever 8 is moved, the value of the micrometer 11 can be read, until the measurement of all tooth profile values ​​of the entire circumference is completed, and the measurement of all MRK values ​​on a gear plate 4 to be measured is completed.

[0041] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
