Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0023] The embodiment of the present application provides a method to solve the technical problem of inconvenient valve opening in the prior art.

[0024] The technical solution in the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows:

[0025] like Figure 1 As shown, the present application provides a valve turntable clamp, comprising:

[0026] A base 10, wherein a plurality of clamping mechanisms 20 are disposed on the base 10;

[0027] The transition shaft 11 is fixedly disposed on the base 10 . The transition shaft 11 and the clamping mechanism 20 are located on the front and back sides of the base 10 .

[0028] The clamping mechanism 20 is clamped on the valve turntable, and then the transition shaft 11 is driven by the motor to rotate, thereby driving the base 10 and the clamping mechanism 20 to rotate together, and finally the valve turntable is opened or closed.

[0029] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] Preferably, the base 10 includes a plurality of support arms 12 evenly distributed around a circumference, and the clamping mechanisms 20 are arranged on corresponding support arms 12 , and the number of the clamping mechanisms 20 is at least three.

[0031] Specifically, a track 13 is fixedly provided on the end surface of the base 10 , a slider 21 is fixedly provided on the clamping mechanism 20 , and the clamping mechanism 20 is slidably provided on the track 13 via the slider 21 .

[0032] The turntable clamp also includes an adjustment mechanism 30, which includes a fixed block 31 and a screw 32. Multiple clamping mechanisms 20 are arranged around the fixed block 31. The screw 32 is arranged along the length direction of the track 13. The screw 32 passes through the clamping mechanism 20 and is rotatably connected to the fixed block 31.

[0033] By rotating the lead screw 32, the lead screw 32 rotates on the fixed block 31, and the lead screw 32 and the clamping plate 22 of the clamping mechanism 20 rotate relative to each other, so that the clamping plate 22 drives the slider 21 to move on the track 13, and the clamping claw 23 is adjusted to a suitable position and clamped on the valve turntable.

[0034] or,

[0035] The turntable clamp also includes a fixed block 31 and a telescopic rod. A plurality of the clamping mechanisms 20 are arranged around the fixed block 31. The telescopic rod is arranged along the length direction of the track 13. The telescopic rod is fixedly arranged on the fixed block 31. The telescopic end of the telescopic rod is fixedly connected to the clamping mechanism 20.

[0036] The telescopic rod is preferably an electric push rod, which drives the clamping plate 22 to move on the track 13, and clamps the clamping claw 23 on the valve turntable after adjusting it to a suitable position. Its specific structure is that the screw in the previous embodiment is replaced by an electric push rod, and the relevant views are no longer provided.

[0037] The adjustment mechanism 30 adjusts the corresponding clamping mechanism 20 to act independently, so that the turntable clamp has certain adjustment and compensation functions to adapt to workpieces of different sizes and shapes; and through the cooperation of the slider 21 and the track 13, it helps the workpiece to quickly and accurately enter the clamping position of the clamp and limit the movement range of the workpiece.

[0038] The clamping mechanism 20 includes a clamping plate 22 and a clamping claw 23. The clamping plate 22 is fixedly connected to the slider 21. The clamping claw 23 is fixedly arranged on the clamping plate 22. The clamping claw 23 is a U-shaped structure. The U-shaped clamping claw 23 is clamped on the valve turntable to prevent the clamping mechanism 20 from falling off. The contact surface between the clamp and the workpiece usually has good finish and precision to ensure that the clamp can effectively clamp and position the workpiece.

[0039] A valve rotating device comprises the clamp described in any one of the above technical solutions, wherein the transition shaft 11 of the clamp is connected to a reducer and driven by a motor.

[0040] The motor drives the reducer to rotate, and then drives the base 10 and the clamping mechanism 20 to rotate, so as to realize the opening and closing of the valve, saving time and labor.

[0041] Although the preferred embodiments of the present invention have been described, those skilled in the art may make other changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present invention.

[0042] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
