Technical Field

[0001] The utility model relates to the technical field of valve production, in particular to a positioning device for valve production. Background Art

[0002] A valve is a device used to control the flow of gases, liquids, gases or liquids containing solid powders in various pipelines and equipment. A valve is usually composed of a valve body, a valve cover, a valve seat, a starter and a stopper, a drive mechanism, a seal and fasteners. The control function of the valve is achieved by driving the starter and the stopper to rise and fall, slide, swing or rotate by a ratio to change the size of the flow area.

[0003] During the production process of existing valves, each step requires further processing of the valves. When drilling holes in the valves, a positioning device is required to limit the valves before drilling. However, when the existing positioning devices are used, in order to ensure the fixing effect of the valves, most valves of one size require a set of fixtures. When processing valves of different sizes, the fixtures need to be replaced, which is not only cumbersome, but also reduces the processing efficiency of the valves. Utility Model Content

The two-way threaded rod 3 is guided to be more stable when rotating, so as to avoid the two-way threaded rod 3 being unstable when rotating and affecting the threaded connection between it and the sleeve 4. The top of the sleeve 4 is fixedly connected with a connecting block 5, one side of the connecting block 5 is fixedly connected with a positioning frame 6, and one side of the connecting block 5 on the other side is fixedly connected with a fixing frame 7. The positioning frame 6 and the fixing frame 7 are designed to be staggered with each other. Under this effect, the two sleeves 4 can be driven by the connecting block 5 to move the positioning frame 6 and the fixing frame 7 when moving, so as to squeeze and limit the valve so that it will not move easily. The positioning frame 6 and the fixing frame 7 are both metals with good rebound effect. Under this effect, when valves of different diameters are squeezed and fixed, the positioning frame 6 and the fixing frame 7 It can fully deform to increase the contact area between the positioning frame 6 and the fixing frame 7 and the valve, so that the device has a better fixing effect on valves of different diameters. The inner walls of the positioning frame 6 and the fixing frame 7 are fixedly connected with anti-skid edges 17, and the anti-skid edges 17 are used in conjunction with the positioning frame 6 and the fixing frame 7. Under this action, the friction between the positioning frame 6, the fixing frame 7 and the valve can be increased, thereby improving the stability of the valve. Guide grooves 13 are provided on both sides of the inner cavity of the positioning shell 1, and the inner cavity of the guide groove 13 is slidably connected with a guide block 14. One side of the guide block 14 is fixedly connected to one side of the connecting block 5. Under this action, the connecting block 5 can be guided when it moves, so that it can be more stable when moving, and the sleeve 4 is also prevented from being affected by the two-way thread. Under the action of the thread on the surface of the rod 3, the rod 3 rotates in place. A fixing plate 8 is fixedly connected to the bottom of the inner cavity of the positioning shell 1. A support block 9 is arranged on the top of the fixing plate 8. The support block 9 is designed as a cylinder. A connecting frame 10 is fixedly connected to the bottom of the support block 9. The connecting frame 10 penetrates to the bottom of the fixing plate 8 and is slidably connected to the inner wall of the penetration point. Under this action, when limiting the position of valves of different diameters, the support block 9 can lift the valve, so as to facilitate the processing of the valve. A positioning groove 12 is provided on the inner wall of the connecting frame 10, and a limiting mechanism 11 is installed at the bottom of the fixing plate 8. The limiting mechanism 11 is used in conjunction with the positioning groove 12. Under this action, the position of the support block 9 can be adjusted, so as to facilitate the lifting of the valve.With the cooperation of the limiting mechanism 11, the support block 9 can limit the connection frame 10 through the positioning groove 12 after it moves, so that the support block 9 will not move easily, thereby increasing the lifting effect on the valve.

[0023] The limiting mechanism 11 includes a limiting shell 111, the top of the limiting shell 111 is fixedly connected to the bottom of the fixing plate 8, the inner cavity of the limiting shell 111 is provided with a compression spring 112, both ends of the compression spring 112 are fixedly connected to the limiting block 113, one side of the limiting block 113 is an inclined structure design, the inner cavity of the positioning groove 12 is a wedge-shaped structure design, the limiting block 113 is used in conjunction with the positioning groove 12, under this action, the limiting block 113 can be embedded in the interior of the positioning groove 12, so as to limit the connecting frame 10, and when the position of the support block 9 needs to be moved upward, The connecting frame 10 can be pushed directly, and the limit block 113 will not affect the movement of the support block 9 under the action of the compression spring 112. When the support block 9 needs to be moved downward, the position of the support block 9 can be adjusted by moving the limit block 113. Both sides of the limit block 113 are fixedly connected with a toggle plate 16, and the surface of the toggle plate 16 is slidably connected to the surface of the limit shell 111. Under this action, an effective force point can be provided for the staff when adjusting the limit block 113, thereby making it more convenient for the staff to adjust the limit block 113.

[0024] Working principle: First, according to the size of the valve, directly push the connecting frame 10 so that it can drive the support block 9 to move upward, so as to facilitate the lifting of the valve, and then limit the support block 9 with the cooperation of the limit block 113 and the positioning groove 12. When the support block 9 needs to be adjusted downward, the limit block 113 is pushed by the toggle plate 16 to disengage it from the inside of the positioning groove 12, thereby adjusting the position of the support block 9. After the adjustment, the valve is directly placed on the top of the support block 9, and then the stepper motor 2 is turned on. Under the action of the stepper motor 2, the sleeve 4 and the connecting block 5 are driven to move through the threads on the surface of the bidirectional threaded rod 3. At the same time, under the action of the connecting block 5, the positioning frame 6 and the fixing frame 7 are driven to move in the opposite direction, so as to squeeze and limit the valve so that it will not move easily, and then the valve can be processed.
