[0036] The implementation principle of this embodiment is:

[0037] The worm gear meshing center distance measuring mechanism is provided with a limiting mechanism 2. When it is necessary to detect the meshing center distance of the worm wheel 10 and the worm 3, the staff moves the connecting plate 17 upward, thereby forcing the connecting plate 17 to move upward. Since a slider 19 is provided on one side of the connecting plate 17, the slider 19 can move up and down inside the slide groove 14, thereby enabling the connecting plate 17 to move upward. The upward movement of the connecting plate 17 can drive the upper circular plate 16 to move upward. When the connecting plate 17 moves upward to the top, the staff takes out the worm 3 and puts it on the top of the lower circular plate 15. Then the staff moves the connecting plate 17 downward. When the inner surface of the upper circular plate 16 contacts the outer surface of the worm 3, the staff presses the positioning pin 21, and the positioning pin 21 moves to the right and enters the interior of the positioning hole 18, thereby limiting the connecting plate 17 and limiting the worm 3.

[0038] Then the staff pulls the movable plate 29 backward through the through slot 34, which can force the movable plate 29 to move backward. Since a sliding block 38 is provided at the bottom of the movable plate 29, the sliding block 38 can move inside the sliding slot 28, thereby enabling the movable plate 29 to move backward. The movable plate 29 moves backward, which can squeeze the spring 30 and compress the spring 30. Then the staff takes out the inspection standard part and puts it on the top of the turntable 32. Then the staff puts the sliding ring 11 on the top of the standard part and screws the screw 12 on its outer surface. The screw 12 moves forward and contacts the outer surface of the rotating shaft 33, thereby limiting the sliding ring 11 and enabling the inspection of the standard part. The standard part is limited to prevent it from moving up and down during the inspection process. Then the staff releases the movable plate 29, and the spring 30 recovers its deformation to push the movable plate 29 forward until the standard part is engaged with the worm 3. Then the staff starts the motor 5, and the output shaft of the motor 5 starts to rotate, which can drive the coupling 6 to rotate, and then drive the worm 3 to rotate. Then the staff starts the air pump 23, and the air pump 23 starts to blow air into the air inlet 24. The gas moves to the air outlet 27 through the inside of the base 22, and then the gas passes through the gas flow meter 26 of the air outlet 27. The gas flow meter 26 transmits the numerical value to the display screen 8, and the display screen 8 displays the data, and the staff records the data.

[0039] Then the staff removes the standard parts and takes out the worm wheel 10 to be tested, and fixes it to the top of the turntable 32 according to the above method. After the worm wheel 10 and the worm 3 are engaged, the staff starts the motor 5, and then the worm 3 rotates. The rotation of the worm 3 can drive the worm wheel 10 to rotate. During the rotation of the worm wheel 10, the worm wheel 10 will move back and forth due to the engaged position. The forward and backward movement of the worm wheel 10 can drive the movable plate 29 to move back and forth. The forward and backward movement of the movable plate 29 can drive the second baffle plate 35 to move back and forth. The forward and backward movement of the second baffle plate 35 can change the gas flow through the base 22. Then, through the detection of the gas flow meter 26 and the transmission of data to the display screen 8, the staff records the data and compares it with the previously recorded data to know whether the center distance of the worm wheel 10 and the worm 3 is within the tolerance range when engaged, and then the center distance of the worm wheel 10 is qualified when engaged. Whether it is convenient, fast and accurate detection can be carried out, thereby improving work efficiency.

[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] The worm gear meshing center distance measuring mechanism is provided with a limiting mechanism 2, through which the worm 3 can be limited to prevent it from moving up and down during the detection process. By moving the connecting plate 17 up and down, it can be quickly replaced, thereby saving time. A moving mechanism 9 is provided, and the gas passing through the detection mechanism 7 can be controlled by moving the moving mechanism 9. A detection mechanism 7 is provided, and the flow rate of the gas can be detected by the detection mechanism 7, so that it can conveniently, quickly and accurately detect whether the center distance of the worm wheel 10 and the worm 3 is qualified when meshing, thereby saving detection time and improving work efficiency.

Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
