fig. 2 is a schematic structural view of the fastening force inspection device according to the embodiment of the present invention after fastening.
Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
As shown in fig. 1, the utility model provides a fastening force quick inspection device, including upper cover plate 1, elasticity compression device and lower cover plate 2. The upper cover plate 1 is arranged on the bottom surface of the nut of the fastener bolt 3, and a through hole for the bolt 3 to pass through is arranged on the upper cover plate 1 for the convenience of installation. Corresponding to the upper cover plate 1, the lower cover plate 2 is also provided with through holes through which bolts 3 pass. The elastic compression device comprises a spring 4 connecting the upper cover plate and the lower cover plate, and in the embodiment, in order to facilitate visual reading of the fastening force between the bolt 3 and the nut 5, the elastic compression device further comprises a first groove arranged on the bottom surface of the upper cover plate 1 and a second groove arranged on the lower cover plate 2 and corresponding to the first groove. One end of the spring 4 is fixed in the first groove, the other end of the spring 4 is fixed in the second groove, and when the spring 4 is in a natural extension state, an interval is formed between the upper cover plate 1 and the lower cover plate 2, and the size of the interval between the upper cover plate 1 and the lower cover plate 2 is determined according to the size of fastening force and the deformation amount of the spring. In this embodiment, four elastic compression devices are arranged between the upper cover plate and the lower cover plate, and of course, a corresponding number of elastic compression devices are arranged as required in actual use.
In order to prevent the spring 4 from deviating in position during the compression process to affect the fastening effect, the elastic compression device further comprises a protective sleeve 6, one end of the protective sleeve 6 is fixed in the first groove, the other end of the protective sleeve 6 extends out of the first groove, and in order not to affect the compression of the spring 4, the upper cover plate and the lower cover plate are in fit connection, the length of the protective sleeve 6 is set to be such that when the spring 4 is under enough pressure, the part of the protective sleeve 6 exposed out of the first groove is completely inserted in the second groove.
In the tightening force inspection apparatus according to the present embodiment, the corresponding springs 4 are arranged in advance according to the tightening force requirements, for example, the scaffold is required to tighten the bolts 3 with a torque of 40N · M-M, the springs 4 are arranged according to the torque, the contraction amount of the springs 4 is recorded when the bolt tightening force reaches 40N · M-M, and the distance between the upper and lower cover plates is reserved according to the contraction amount. The upper cover plate and the lower cover plate are connected into an integral structure through the spring 4 and a protective sleeve 6 outside the spring 4 and are arranged on the bottom surface of the nut 5. After the fastener 7 is installed in place, the nut 5 is sleeved on the bolt 3 and the nut 5 is fastened by a wrench, the spring 4 is continuously compressed and the distance between the upper cover plate and the lower cover plate is continuously reduced in the process of fastening the nut 5, and when the spring 4 is compressed and the distance between the upper cover plate and the lower cover plate is reduced to be not reduced, the fastening force of the fastener bolt 3 reaches the fastening torque 40 N.M-M of the design requirement, namely, the fastening is finished.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood that the invention is not limited thereto, and that various modifications and changes can be made by those skilled in the art without departing from the principles of the invention.
