It has the advantages of simple operation, low manufacturing cost, improving measurement and processing accuracy, and enhancing processing efficiency. However, this measurement technology has the following problems.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] As shown in the attached Figures 1-5 For a generator bearing bush parallelism measuring tool, a measuring mechanism is provided on the generator bearing bush parallelism measuring tool. The setting of the measuring mechanism can make the spirit level 8 contact the upper surface of the generator bearing bush under the action of gravity. When the level of the upper surface of the generator bearing bush is zero, the green liquid 11 inside the groove body 10 can be viewed through the transparent plate 9, enabling stable measurement of the generator bearing bush and better measurement effect. The specific structural setting of the measuring mechanism is as follows.

[0021] In this embodiment, as shown in the attached Figures 1-3 figure, the parallelism measuring tool for the generator bearing bush includes a scale 1. A pointed block 2 is fixedly connected to the lower surface of the scale 1. A sliding frame 3 is fixedly connected to one side of the pointed block 2. A measuring mechanism is arranged inside the sliding frame 3. The measuring mechanism includes a screw rod 4 rotatably arranged inside the sliding frame 3. A socket block 5 is threadedly connected to the outer wall of the screw rod 4. A support shaft 6 is fixedly connected to one side of the inner wall of the socket block 5. A sleeve block 7 is rotatably connected to the outer wall of the support shaft 6. A spirit level 8 is fixedly connected to one side of the sleeve block 7. A transparent plate 9 is fixedly connected to one side of the spirit level 8. A groove 10 is formed inside the spirit level 8. A green liquid 11 is arranged inside the groove 10. A socket slider 14 is slidably connected to the outer wall of the scale 1. An indicating tip 15 is fixedly connected to the bottom end of the socket slider 14.

[0022] In this embodiment, as shown in the attached Figures 2-3 figure, a buckle block 12 is fixedly connected to one end of the spirit level 8. A rotary cap 13 is fixedly connected to the bottom end of the screw rod 4. The cross-sectional shape of the rotary cap 13 is polygonal to facilitate the rotation of the rotary cap 13. The rotary cap 13 drives the screw rod 4 to rotate. The screw rod 4 rotates inside the sliding frame 3. The finger is held inside the buckle block 12, which is convenient for the lower surface of the spirit level 8 to contact the upper surface of the generator bearing bush.

[0023] When the parallelism measuring tool for the generator bearing bush of the present technology is in use, the pointed block 2 is located on the left side of the generator bearing bush, and at the same time, the indicating tip 15 is located on the right side of the generator bearing bush. In this way, the socket slider 14 is pushed to the left. The socket slider 14 slides to the left along the outer wall of the scale 1. The socket slider 14 drives the indicating tip 15 to move leftward. The indicating tip 15 presses against the right side of the generator bearing bush. At the same time, the pointed block 2 presses against the right side position of the generator bearing bush, and the locking operation of the generator bearing bush can be carried out.

[0024] Then the rotary cap 13 is rotated. The rotary cap 13 drives the screw rod 4 to rotate. The screw rod 4 rotates inside the sliding frame 3. The screw rod 4 drives the socket block 5 to move downward under the action of the threaded driving force. The socket block 5 slides down along the inner wall of the sliding frame 3. At the same time, the socket block 5 drives the support shaft 6 to move downward. The support shaft 6 drives the sleeve block 7 to move downward. The sleeve block 7 makes the spirit level 8 move downward. The lower surface of the spirit level 8 contacts the upper surface of the generator bearing bush. The finger is held inside the buckle block 12. At the same time, the rotary cap 18 is rotated. The rotary cap 18 drives the rotating shaft 17 to rotate counterclockwise by 90 degrees. The bearing block 16 makes the magnet 19 rotate counterclockwise by 90 degrees. The magnet 19 and the iron block 20 are no longer magnetically connected, and the buckle block 12 can be released. In this way, under the action of gravity, the spirit level 8 contacts the upper surface of the generator bearing bush. When the levelness of the upper surface of the generator bearing bush is zero, the green liquid 11 inside the groove 10 is viewed through the transparent plate 9. When the green liquid 11 is in a parallel state, the measurement of the upper surface of the generator bearing bush is in a qualified state. When the green liquid 11 shows an inclination problem, the measurement of the upper surface of the generator bearing bush is in an unqualified state.

[0025] In this embodiment, as shown in the Figures 4-5 accompanying drawings, a separation component is provided on one side of the socket block 5; the separation component includes a bearing block 16 fixedly arranged on one side of the socket block 5, and a rotating shaft 17 is rotatably connected to the inner wall of the bearing block 16. A rotating cap 18 is fixedly connected to the top end of the rotating shaft 17, and a magnet 19 is fixedly connected to the bottom end of the rotating shaft 17; an iron block 20 is magnetically attracted to the bottom end of the magnet 19, and a fixed connection is provided between the iron block 20 and the spirit level 8. The cross-sectional area of the rotating shaft 17 is smaller than the cross-sectional area of the rotating cap 18, and the cross-sectional shape of the rotating cap 18 is polygonal.

[0026] When the present technology is in use, the rotating cap 18 drives the rotating shaft 17 to rotate counterclockwise by 90 degrees at the same time, and the bearing block 16 causes the magnet 19 to rotate counterclockwise by 90 degrees. The magnet 19 and the iron block 20 are no longer magnetically attracted to each other. In this way, under the action of gravity, the spirit level 8 contacts the upper surface of the generator bearing bush, facilitating the contact between the spirit level 8 and the generator bearing bush for measurement operations.

[0027] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
