Detailed ways

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific embodiments.

As shown in Figure 1-2, a special fixture for notch twisting torque processing, including a fixture base plate 1, a workpiece 2 and an adjustable micrometer 4, the middle part of the top of the fixture base plate 1 is fixed with a fixed mandrel 3, and the fixed mandrel 3 is fixed The workpiece 2 is set on the sleeve, and an adjustable micrometer 4 is provided on one side of the top of the fixture bottom plate 1. The middle part of the adjustable micrometer 4 is fixedly connected to the top of the fixture bottom plate 1 through the first fixing structure 5, and the other side of the top of the fixture bottom plate 1 is provided. There is a torque wrench 8, the middle part of the torque wrench 8 is fixed with the fixture base plate 1 through the second fixing structure 7, and one end of the torque wrench 8 is threadedly connected with the workpiece screw 6 on the workpiece 2.

Wherein, one side of the fixture bottom plate 1 is provided with a slot 10 matching the size of the notch of the workpiece 2 to correct the position of the workpiece 2 and facilitate the next processing operation.

Wherein, the first fixing structure 5 includes a fixing card, a compression screw and a screw, and the top and one side of the fixing card are respectively fixed with a compression screw and a screw, so as to facilitate fixing and dismounting of the adjustable micrometer 4 .

Wherein, the second fixing structure 7 includes a fixing snap ring and bolts 9, and the two sides of the fixing snap ring are provided with bolts 9 to facilitate the fixing and dismounting of the torque wrench 8, avoid moving the torque wrench 8 back and forth, and improve work efficiency.

Among them, one end of the adjustable micrometer 4 is in contact with the workpiece 2, and the contact point between the workpiece 2 and the adjustable micrometer 4 is the reference point. The operator can quickly and accurately correct the workpiece 2 through the adjustable micrometer 4, so that the workpiece 2 The notch is symmetrical and parallel to the slot 10 of the fixture bottom plate 1 .
