[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Please see Figure 1-3 This embodiment provides the following technical solution: a valve body turning fixture, including two fixture bodies 1, which are detachably connected. Each fixture body 1 has a fixture groove 2 on one side facing the other. The two fixture grooves 2 work together to form a receiving cavity structure for the valve body, which facilitates the direct placement of the valve body into the receiving cavity.

[0028] It also includes a fixing component for fixing the two clamping bodies 1. The fixing component includes a first positioning hole 5, a second positioning hole 6 and a fixing bolt. The first positioning hole 5 is set on one of the clamping bodies 1, and the second positioning hole 6 is set on the other clamping body 1. One end of the fixing bolt passes through the first positioning hole 5 and is threadedly connected to the second positioning hole 6. The two clamping bodies 1 can be disassembled and fixed by the fixing bolt.

[0029] One of the clamping bodies 1 is provided with a clamping groove 3 that communicates with the clamping groove 2. A clamping plate 4 is movably connected in the clamping groove 3. A clamping element is provided on the clamping body 1 to drive the clamping plate 4 to move. The clamping plate 4 and the clamping element work together to form a squeezing structure for the valve body. By providing the clamping plate 4, not only is the clamping efficiency of the valve body improved, but the contact area with the valve body is also increased, and the pressure distribution is more uniform. This avoids the valve body from deforming or damaging its surface due to uneven force, thereby improving the processing quality of the valve body.

[0030] In some embodiments, multiple clamping members are provided, and the multiple clamping members are spaced apart on the clamping body 1. Each clamping member includes a clamping bolt and a clamping hole 7. One end of the clamping bolt passes through the clamping hole 7 provided on the clamping body 1 and is fitted to the clamping plate 4. By providing multiple clamping bolts, the clamping plate 4 can be fixed at multiple points, making it easier to bring the clamping plate 4 close to the valve body and fix the valve body inside the receiving cavity.

[0031] In some embodiments, the clamping groove 3 is a convex groove, which can limit the left and right directions of the clamping plate 4 and allow the clamping plate 4 to slide in the left and right directions within the clamping groove 3. Moreover, since the front and rear ends of the clamping groove 3 penetrate the clamping body 1, it is convenient for manual removal or insertion of the clamping plate 4 into the clamping groove 3.

[0032] The working principle of this embodiment is as follows: When in use, the two clamping bodies 1 are combined and fixed together by fixing bolts. Then, the valve body to be processed is slid into the receiving cavity, and the clamping plate 4 is slid into the clamping groove 3. Then, the clamping bolts are installed into the corresponding clamping holes 7 in sequence. By turning the clamping bolts, the clamping plate 4 is moved toward the valve body, so that the clamping plate 4 presses and fixes the valve body in the receiving cavity, thereby allowing the valve body on the clamping body 1 to be processed.

[0033] Example 2

[0034] Please see Figure 4-7 To better drive the clamping plate 4 to clamp and fix the valve body, the clamping components may also include a mounting plate 8, a drive plate 10, and clamping rods 12. The mounting plate 8 is detachably connected to the mounting cavity 9 provided on the clamping body 1. The mounting cavity 9 is provided with a drive cavity 11. The drive plate 10 is slidably connected in the drive cavity 11. Multiple clamping rods 12 are fixedly connected to the drive plate 10 at intervals. The clamping rods 12 pass through the holes and slots on the clamping body 1 and extend into the clamping groove 3. The mounting plate 8 is threaded with a fastening bolt. The other end of the fastening bolt is rotatably connected to the drive plate 10. With the drive plate 10 and the clamping plate 4, only a single fastening bolt is needed to clamp and fix the valve body, which replaces the problem of having to tighten each clamping bolt in turn to clamp and fix the valve body, further improving the efficiency of fixing the valve body.

[0035] The moving cavity is also equipped with a buffer spring 13 that is movably sleeved on the clamping rod 12. Both ends of the buffer spring 13 are fixedly connected to connecting plates. One connecting plate is fixedly connected to the drive plate 10, and the other connecting plate is slidably sleeved on the clamping rod 12. The buffer spring 13 can play a buffering role when the clamping rod 12 drives the clamping plate 4 to move, thereby buffering the hard contact between the clamping plate 4 and the valve body.

[0036] The mounting plate 8 is also provided with bolt holes 14 for locking bolts to pass through. The locking bolts pass through bolt holes 14 and are threadedly connected to the clamping body 1. The mounting plate 8 can be disassembled and assembled through the bolt holes 14, so that the drive block and clamping rod 12 can be taken out or installed inside the drive cavity 11.

[0037] The working principle of this embodiment is as follows: When in use, the two clamping bodies 1 are combined and fixed together by fixing bolts. Then, the valve body to be processed is slid into the receiving cavity, and the clamping plate 4 is slid into the clamping groove 3. Then, the fastening bolt is turned so that the fastening bolt rotates and drives the drive plate 10 to slide in the drive cavity 11. At the same time, the drive plate 10 can compress the buffer spring 13. As the clamping rod 12 continues to extend into the clamping groove 3, the clamping plate 4 moves towards the valve body until the clamping plate 4 contacts the valve body. When the buffer spring 13 reaches its maximum deformation, the valve body is fixed.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
