Description

Technical Field

[0001] The utility model belongs to the technical field of fully enclosed rotary compressor pump bodies, and particularly relates to a shaft keyway positioning tool. Background Art

[0002] The overall tooling is driven to rotate by the rotating shaft 6 of the motor, and the first positioning key 4 is installed in the groove of the base 1. The first positioning key 4 is provided with a spring 5 that can be extended and retracted up and down. The pressure plate 2 is fixed to the base 1 by screws 3 and the first positioning key 4 is positioned by the pressure plate 2. When the tooling positioning key 4 is at a different angle from the shaft keyway, the first positioning key 4 is compressed; when the first positioning key is rotated to the same angle as the crankshaft keyway, the first positioning key 4 is ejected by the spring and enters the keyway to achieve angular positioning of the workpiece. The first positioning key 4 of the positioning device is easy to wear, and when wear occurs, the corresponding function cannot be realized, and the first positioning key needs to be replaced in time, resulting in reduced efficiency and increased costs. Summary of the invention

[0003] In view of the above shortcomings, the purpose of the utility model is to provide a shaft keyway positioning tool to solve the problem of needing to replace the positioning key in time to ensure production efficiency.

[0004] The technical solution adopted by the utility model is: a shaft keyway positioning tool, whose technical points are: it includes a guide sleeve and a support plate arranged on the outside of the guide sleeve, and two spring plungers arranged up and down are connected through the support plate, and one end of the spring plunger is against the positioning key rotatably connected in the guide sleeve. The positioning key is forced to move backward and the spring plunger is compressed, and the compressed spring plunger provides the driving force for the positioning key to enter the keyway.

[0005] In the above solution, the positioning key is connected in the guide sleeve via a pin.

[0006] In the above solution, the support plate is fixedly connected to the outer side wall of the guide sleeve by screws.

[0007] The beneficial effects of the utility model are as follows: a shaft keyway positioning tool comprises a guide sleeve and a support plate arranged outside the guide sleeve, two spring plungers arranged up and down to provide a swing force for the positioning key are connected through the support plate, and the swing angle of the positioning key can be adjusted by adjusting the protruding length of the elastic plunger. When the working surface of the positioning key is worn, the pop-up length of the positioning key can be increased by adjusting the pop-up length of the elastic plunger, so that the tool can still be used normally under a certain degree of wear, thereby increasing the service life of the tool, thereby achieving the purpose of reducing manufacturing costs and improving work efficiency.

[0017] To make the above-mentioned purpose, features and advantages of the present invention more obvious and easy to understand, the following is a brief description of the present invention in conjunction with the attached Figure 1-Figure 7 The utility model is further described in detail with specific implementation methods.

[0018] The shaft keyway positioning tooling structure adopted in this embodiment includes a guide sleeve 7, and a support plate 8 is connected to the outside of the guide sleeve 7. The support plate 8 is fixed to the outer wall of the guide sleeve 7 by screws 2. Two spring plungers 9 arranged up and down are connected through the support plate 8. The two spring plungers 9 can be adjusted forward and backward. One end of the two spring plungers 9 is pressed against the outer wall of the positioning key 5. The positioning key 10 is rotatably connected in the guide sleeve 7 through a rotating pin 11. The swing angle of the positioning key 10 can be adjusted by adjusting the protruding length of the elastic plunger 9. When the working surface of the positioning key 10 is worn, the pop-up length of the elastic plunger 4 can be adjusted to increase the pop-up length of the positioning key 10, so that the tooling can still be used normally under a certain degree of wear. In this embodiment, a sealing ring 12 is also provided at the bottom of the guide sleeve 7 to protect the bottom of the guide sleeve 7, so that there is a certain buffer when the tooling falls into the guide sleeve 7.

[0019] The working process of the shaft keyway positioning tool in this embodiment is as follows:

[0020] After the tooling is inserted into the guide sleeve 7, the positioning key 10 moves backward and the elastic plunger 9 is compressed. When the motor drives the tooling to rotate axially, when the positioning key 10 and the keyway are at the same angle, the elastic plunger 9 rebounds and the positioning key 10 enters the keyway. When the working part of the positioning key 10 is worn, the elastic plunger 9 is adjusted forward and the tooling can continue to be used.

[0021] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
