Technical Field

[0001] The utility model relates to the technical field of ball valve processing, in particular to an anti-offset mechanism for ball valve processing. Background Technique

[0002] A ball valve is a valve in which the closing member (ball) is driven by a valve stem and rotates around the axis of the ball valve. It can also be used for the regulation and control of fluids. Among them, the hard-sealed V-type ball valve has a strong shearing force between its V-type ball core and the metal valve seat with surfacing hard alloy, and is especially suitable for media containing fibers, tiny solid particles, etc. The multi-way ball valve can not only flexibly control the confluence, shunt, and flow direction switching of the medium on the pipeline, but also close any channel to connect the other two channels. At present, the ball valves on the market generally include a valve body, a valve seat, and a spherical valve core. The valve body is generally symmetrically provided with two, and the spherical valve core is fixed in the middle of the valve body through a connection between the two valve bodies. Therefore, it is necessary to drill holes in the two valve bodies to facilitate the connection between them. However, during the drilling process of the valve body by the existing ball valve processing equipment, due to vibration, the center of the clamped valve body is offset, resulting in inaccurate drilling. Content of the Utility Model

[0003] The purpose of the utility model is to provide an anti-offset mechanism for ball valve processing in view of the deficiencies of the prior art, so as to solve the situation that during the drilling process of the valve body by the existing ball valve processing equipment, due to vibration, the center of the clamped valve body is offset, resulting in inaccurate drilling as mentioned in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: an anti-offset mechanism for ball valve processing, including a clamping structure, and a drilling structure is arranged directly above the clamping structure;

[0005] The clamping structure includes a clamping table, a cylinder is fixedly arranged on the clamping table, one end of the cylinder is fixedly connected with an adjusting plate, and adjusting holes are symmetrically arranged at both ends of the adjusting plate;

[0006] The clamping table is rotationally connected with a movable plate through a connecting shaft, the connecting shaft is located in the center of the movable plate, one side of the movable plate slides and adjusts in the adjusting hole, and the other side is fixedly connected with an adjusting block.

[0007] By adopting the above technical solution, the piston rod in the cylinder drives the adjusting plate to move left and right through expansion and contraction, so that one side of the movable plate slides in the adjusting hole, the middle of the movable plate rotates with the clamping table, and the other side of the movable plate moves relatively closer or farther away, thus achieving a relative adjustment effect.

[0008] Preferably, a first arc-shaped adjusting block is fixedly connected to the adjusting block, two arc-shaped grooves are symmetrically arranged on the first arc-shaped adjusting block, and a second arc-shaped adjusting block is slidably connected in the arc-shaped grooves.

[0009] Preferably, two arc-shaped grooves are symmetrically formed on the second arc-shaped adjusting block, and a third arc-shaped adjusting block is slidably connected in the arc-shaped grooves on the second arc-shaped adjusting block.

[0010] Preferably, two arc-shaped grooves are symmetrically formed on the third arc-shaped adjusting block, and a fourth arc-shaped clamping block is slidably connected in the arc-shaped grooves on the two arc-shaped grooves.

[0011] By adopting the above technical solution, when the two adjusting blocks approach or move away from each other, they will drive the two first arc-shaped adjusting blocks to approach or move away from each other relatively, so that the second arc-shaped adjusting block, the third arc-shaped adjusting block and the fourth arc-shaped clamping block slide and adjust in the grooves formed in the first arc-shaped adjusting block, the second arc-shaped adjusting block and the third arc-shaped adjusting block respectively.

[0012] Preferably, an elastic member is fixedly arranged on the clamping table, and the elastic member is located at the exact center of the clamping structure.

[0013] By adopting the above technical solution, the ball valve to be clamped is fixed at the exact center of the clamping structure through the arranged elastic member, preventing the ball valve from shifting during the clamping process.

[0014] Preferably, the drilling structure includes an electric push rod, one end of the electric push rod is fixed on the clamping table, and the other end is fixedly connected with a motor.

[0015] By adopting the above technical solution, the arranged electric push rod is used to push the entire drilling structure to move up and down, thereby achieving the effect of up and down adjustment.

[0016] Preferably, the motor drives a planetary gear to rotate, and the gear on the planetary gear and the drill bit are fixedly connected respectively.

[0017] By adopting the above technical solution. The motor drives the planetary gear to rotate, so that the drill bit fixedly connected with the gear on the planetary gear rotates, and then drills the ball valve to be processed.

[0018] Compared with the prior art, the beneficial effect of the present utility model is: the anti-offset mechanism for ball valve processing,

[0019] (1) In this case, by setting the clamping structure, the problem that in the process of drilling the valve body by the existing ball valve processing equipment, due to vibration, the center of the clamped valve body is offset, resulting in inaccurate drilling, is solved. The piston in the cylinder expands and contracts, causing one side of the two movable plates to slide in the adjustment holes on the adjustment plate, and the other side to approach or move away from each other. This drives the second arc adjustment block, the third arc adjustment block, and the fourth arc clamping block to slide and adjust in the grooves opened in the first arc adjustment block, the second arc adjustment block, and the third arc adjustment block respectively, so as to clamp valve bodies of different diameters. At the same time, by setting the elastic member, the valve body is fixed in the center of the clamping structure to prevent the center of the valve body from shifting during the clamping process. Moreover, the elastic member has elasticity and can be applied to valve bodies of different sizes, and the clamping can also adjust the position of different sizes on the valve body.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-3 , the present utility model provides a technical solution: an anti-offset mechanism for ball valve processing;

[0026] As Figure 1 and Figure 3As shown in the figure, it includes a clamping structure 1. The clamping structure 1 includes a clamping table 101. A cylinder 102 is fixedly arranged on the clamping table 101. One end of the cylinder 102 is fixedly connected to an adjusting plate 103. Adjusting holes 104 are symmetrically opened at both ends of the adjusting plate 103. The clamping table 101 is rotationally connected to a movable plate 105 through a connecting shaft. The connecting shaft is located in the center of the movable plate 105. One side of the movable plate 105 slides and adjusts in the adjusting hole 104, and the other side is fixedly connected to an adjusting block 106. Among them, when the piston rod in the cylinder 102 drives the adjusting plate 103 to move left and right through expansion and contraction, during the left and right movement of the adjusting plate 103, the two movable plates 105 rotate around the connecting shaft and the clamping table 101. During the rotation of the two movable plates 105, one side of them slides in the adjusting hole 104 on the adjusting plate 103, and the other side moves closer to or away from each other.

[0027] In the above solution, further, a first arc-shaped adjusting block 107 is fixedly connected to the adjusting block 106. Two arc-shaped grooves are symmetrically opened on the first arc-shaped adjusting block 107. A second arc-shaped adjusting block 108 is slidably connected in the arc-shaped grooves. Two arc-shaped grooves are symmetrically opened on the second arc-shaped adjusting block 108. A third arc-shaped adjusting block 109 is slidably connected in the arc-shaped grooves on the second arc-shaped adjusting block 108. Two arc-shaped grooves are symmetrically opened on the third arc-shaped adjusting block 109. A fourth arc-shaped clamping block 110 is slidably connected in the arc-shaped grooves on the two arc-shaped grooves. An elastic member 111 is fixedly arranged on the clamping table 101. The elastic member 111 is located at the exact center of the clamping structure 1. When the other sides of the two movable plates 105 move closer to or away from each other, the two first arc-shaped adjusting blocks 107 move closer to or away from each other. At this time, the valve body to be processed is sleeved on the elastic member 111 on the clamping table 101, so as to fix the central position of the valve body and prevent its central offset during clamping, which may lead to inaccurate drilling. When the two first arc-shaped adjusting blocks 107 move closer to each other, the second arc-shaped adjusting block 108, the third arc-shaped adjusting block 109, and the fourth arc-shaped clamping block 110 move closer to each other. When the fourth arc-shaped clamping block 110 contacts the valve body, it will slide in the groove opened on the third arc-shaped adjusting block 109. During the sliding of the fourth arc-shaped clamping block 110, the third arc-shaped adjusting block 109 slides in the groove opened on the second arc-shaped adjusting block 108. During the sliding of the third arc-shaped adjusting block 109, the second arc-shaped adjusting block 108 slides in the groove opened on the first arc-shaped adjusting block 107. When the fourth arc-shaped clamping block 110 fits onto the valve body, the sliding between the first arc-shaped adjusting block 107 and the second arc-shaped adjusting block 108, the second arc-shaped adjusting block 108 and the third arc-shaped adjusting block 109, and the third arc-shaped adjusting block 109 and the fourth arc-shaped clamping block 110 stops, thereby fixedly clamping the valve body. And the elastic member 111 has elasticity and can be applicable to valve bodies of different sizes. The clamping can also adjust the position of different-sized parts on the valve body.

[0028] As Figure 2 shown, there is a drilling structure 2 directly above the clamping structure 1. The drilling structure 2 includes an electric push rod 201. One end of the electric push rod 201 is fixed on the clamping table 101, and the other end is fixedly connected to the motor 202. The motor 202 drives the planetary gear 203 to rotate. The gear on the planetary gear 203 and the drill bit 204 are respectively fixedly connected. After the valve body is clamped and fixed, the motor 202 is driven to drive the planetary gear 203 to rotate. During the rotation of the planetary gear 203, the drill bit 204 is driven to rotate. At this time, the electric push rod 201 pushes the motor 202 downward to drill the clamped valve body.
