Description

Stress application device

Technical Field

The utility model relates to the technical field of workpiece loading and unloading, in particular to a stress application device.

Background

As shown in fig. 5 to 6, when the workpiece 4 and the workpiece 5 are butted, the workpiece 5 needs to be translated and pushed along the central axis of the workpiece 4, and the thrust is continuously applied to the workpiece 5 to enable the sealing ring 41 between the workpiece 5 and the workpiece 4 to be extruded and contracted, so that the key slot of the workpiece 5 and the key slot of the workpiece 4 are aligned, and a plurality of key tips 6 are put between the key slot of the workpiece 5 and the key slot of the workpiece 4 through key holes by a worker, so that the workpiece 5 and the workpiece 4 are butted; when the A workpiece 4 and the B workpiece 5 are disassembled, after the plurality of key tips 6 between the A workpiece 4 and the B workpiece 5 are disassembled, the B workpiece 5 needs to be disassembled along the central axis of the A workpiece 4, so that the damage to the A workpiece 4 and the B workpiece 5 is avoided. Therefore, in the process of loading and unloading the A workpiece 4 and the B workpiece 5, the A workpiece 4 and the B workpiece 5 are positioned on the same central axis and are key factors for determining loading and unloading effects, but in the actual loading and unloading process, the movement of the B workpiece 5 and the friction between the A workpiece 4 and the B workpiece 5 can cause fine deviation of the coaxiality of the A workpiece 4 and the B workpiece 5, so that the A workpiece 4 and the B workpiece 5 are blocked or the joint is damaged.

In the prior art, a device for finely adjusting coaxiality in the process of loading and unloading workpieces is not realized, for example, an utility model patent-CN 107953106A-small missile cabin butt joint tool, and the stressing compression ring in the patent can only ensure complete butt joint of the workpiece A4 and the workpiece B5 when the workpiece A4 and the workpiece B5 are completely positioned on the same central axis, and the movement of the workpiece B5 and the friction between the workpiece A4 and the workpiece B5 can cause fine deviation of coaxiality of the workpiece A4 and the workpiece B5, so that the condition that the workpiece is blocked or the joint of the workpiece is damaged occurs, and the stable and efficient loading and unloading operation of the workpiece cannot be ensured.

Therefore, how to realize fine adjustment of coaxiality in the workpiece loading and unloading process is a problem to be solved urgently by the person skilled in the art.
