Detailed Description

To illustrate the objects, technical solutions and advantages of the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Example 1

As shown in fig. 1, it is the utility model discloses a component structure schematic diagram of a special sleeve device for torque wrench, include: the device comprises a fixing pin 1, an end cover 2, a hexagonal block 3 and a sleeve 4; wherein the content of the first and second substances,

the fixing pin 1 is used for matching with a hole of a lock plate nut, provides a direct force application point when being screwed, and is a main working part of the device;

the end cover 2 is used for providing an installation position for the hexagonal block;

the hexagonal block 3 is used for being matched with a torque wrench and providing an indirect force application point when being screwed;

and the sleeve 4 is used for giving out a construction position and guiding when the locking plate nut is screwed in a narrow space, and providing a transmission torque.

The connection relationship of the components is as follows: the hexagonal block is installed on the end cover, and the end cover welding is on the sleeve, and 2 fixed pin interference fit symmetries are installed in telescopic 2 side downtheholess.

The specific working process of the device is as follows:

firstly, the sleeve is sleeved in a space between a wheel shaft and a wheel rim along the axial direction, 2 fixing pins are aligned by the pushing device and inserted into 2 holes on the lock plate nut, and then the end cover end face is attached to the end face of the lock plate nut by the pushing device, and a torque wrench is sleeved on a hexagonal block to apply force to meet the requirement of tightening torque.

The skilled person will appreciate that the above connection is only a preferred embodiment, and not limited thereto, for example, the fixed connection between the end cap and the hexagonal block and the sleeve may be made of a single piece of raw material, or may be welded separately, and any existing fixed connection may be selected, as long as the overall robustness and the effectiveness of torque transmission are ensured. Meanwhile, the number of the fixing pins is not limited to 2, and the number of the fixing pins can be 3, 4 or more for better transmitting the torque. Of course, the connection between the fixing pin and the end cap is not limited to interference fit, and may be any existing retention connection manner, such as welding, magnetic attraction connection, and the like.

In order to explain the contents and embodiments of the present invention, specific examples are given in the present specification. The introduction of details in the examples is not intended to limit the scope of the claims but rather to aid in the understanding of the present disclosure.
