[0019] The utility model will be described in detail below in connection with each embodiment shown in the drawings. But these embodiments do not limit the utility model, and the conversion of structure, method or function made by the ordinary skill in the art according to these embodiments is included in the protection scope of the utility model.

[0020] The terms used herein, such as “above,” “over,” “below,” and “under,” indicating spatial relative position, are for illustrative purposes to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. The terms of spatial relative position may be intended to include different orientations of the device in use or operation other than those shown in the figures. For example, if the device in the figures is flipped, a unit described as being “below” or “under” other units or features would be located “above” other units or features. Therefore, the exemplary term “under” can encompass both above and below orientations. The device may be oriented in other ways, and the spatially related descriptive terms used herein will be interpreted accordingly.

[0021] like Figs. 1 to 4 As shown, a turntable bearing locking nut tightening fixture includes a base 1, a pin 2 slidably disposed on the base 1, a spring 3 disposed between the pin 2 and the base 1, a side screw 4 disposed on the side of the base 1, and a cover plate 5 disposed on the top of the base, and the cover plate 5 is fixed by a top screw 6.

[0022] The base 1 is provided with a sliding groove, and the pin 2 is slidably disposed in the sliding groove. The length of the sliding groove in the base 1 can be changed to adjust the travel of the pin 2, thereby increasing the range of use. A spring 3 is located in the sliding groove; both ends of the spring 3 are connected to the pin 2 and the base 1 respectively to provide elastic force. One end of the pin 2 is in contact with and adhered to a locking nut. By tightening the side screw 4, the pin 2 can be moved. The length of the sliding groove in the base 1 can be changed to adjust the travel of the pin 2, thereby increasing the range of use. The side screw 4 is threadedly connected to the base 1. Square holes 101 are provided on both sides of the base 1 for mounting torque wrenches.

[0023] The square hole 101 has a side length of 6.3mm and 12.6mm, which is suitable for two commonly used torque wrenches. The pin 2 is used to position and fix the locking nut 7. According to the size of the locking nut 7, the side screw 4 is tightened or loosened. Through the compression or extension of the spring 3, the pin 2 moves continuously to adjust the spacing of the pin 2 so that the spacing is exactly consistent with the locking nut 7. This embodiment is installed on the locking nut 7, the torque wrench is placed on the base 1, and the nut is tightened to achieve the expected torque.

[0024] The principle of this utility model is as follows: The locking nut 7 is placed inside the base 1 in this embodiment. By adjusting the side screw 4, the pin 2 is moved radially. That is, when the side screw 4 moves, its end contacts and pushes the pin 2, thereby causing the pin 2 to move. The end of the pin 2 facing the locking nut 7 contacts and clamps the locking nut 7, thereby completing the fixing of the locking nut 7. Specifically, when the pin 2 moves, the spring 3 is deformed and compressed. When the fixing of the locking nut 7 is released, the pin 2 rebounds under the elastic force of the spring 3.

[0025] Further, the torque wrench is installed on the square hole 101 to perform the tightening operation, and the nut is tightened to reach the expected torque size.

[0026] It should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the specification is described in this way only for clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that those skilled in the art can understand.

[0027] The series of detailed descriptions listed above are only specific descriptions of the feasible embodiments of the present application, and are not used to limit the protection scope of the present application. Any equivalent embodiments or changes made without departing from the spirit of the present application should be included in the protection scope of the present application.
