Description

Technical Field

[0001] The utility model relates to the technical field of rotating shaft processing, in particular to a multi-adaptive shaft kit fixture. Background Art

[0002] The shaft is one of the most commonly used parts on various equipment. The shaft kit is a part that is mounted on the shaft and is used to realize the rotational connection between the shaft and the rotating body. When the shaft kit is processed, the detection of the diameter of the shaft hole and whether the shaft hole is tilted are important detection items to measure whether the processing of the shaft kit meets the standards. If the diameter of the shaft hole of the shaft kit is too large, it will cause a large shake when the shaft kit rotates, greatly reducing the stability of the rotating body; if the diameter of the shaft hole of the shaft kit is too small, the shaft cannot pass through; if the shaft hole of the shaft kit is tilted, it will also cause the shaft to be unable to pass through. Therefore, after the shaft kit is processed, it is necessary to strictly detect the diameter of the shaft hole and whether the shaft hole is tilted. During the detection process, a fixture will be used to fix the shaft kit to prevent the shaft kit from loosening during the detection process and improve the accuracy of the detection.

[0003] In the prior art, there is a Chinese patent with application number 201821732026.5, authorization publication number CN209078301U, and invention name "A punching machine fixture for axial punching of stepped shaft parts". The above patent discloses a punching machine fixture for axial punching of stepped shaft parts, which is used in the field of mechanical processing fixtures. The key points of its technical solution are: it includes a base and a first fixture and a second fixture arranged on the base, the first fixture is fixedly connected to the base, the second fixture is slidably connected to the base, the second fixture is driven to move by a screw rod, and the first fixture and the second fixture are opposite to each other on one side along the vertical direction. A fan-shaped first groove is opened, a first support block is arranged in the first groove of the first fixture, and a second groove is opened in the first groove along the vertical direction.

[0004] The above patent can improve the application range of the first clamp and the second clamp, so that the tooling can be processed into holes of different depths by the punching machine. It is known that when a shaft kit needs to be punched, the shaft kit needs to be fixed, but the existing technology such as the above patent cannot pre-fix the shaft kit when clamping the shaft kit. The shaft kit can only be placed in a predetermined position and then clamped and fixed by a clamp, which has certain shortcomings. Utility Model Content
