Technical Field
[0001] This utility model relates to the field of valve processing, and in particular to an adjustable support platform for valve precision machining. Background Technology
[0002] In existing technologies, valves are control elements in fluid pipeline systems. Their main functions are to isolate equipment and pipeline systems, regulate flow, prevent backflow, and regulate and release pressure. They can be used to control the flow of various types of fluids, such as air, water, steam, various corrosive media, mud, oil, liquid metals, and radioactive media. With the development of society, the application of pipeline valves is becoming more and more widespread. Therefore, the demand for a positioning device for pipeline valve processing is increasing.
[0003] Most positioning devices used in the market for pipeline valve processing have simple structures and single functions. They are not convenient for clamping and positioning valves during processing, cannot automatically clamp valves, and cannot clamp valves of different sizes, resulting in the need to frequently change clamps. Utility Model Content

They are not convenient for clamping and positioning valves during pipeline valve machining, cannot automatically clamp valves, and cannot clamp valves of different sizes, resulting in the need to frequently change the clamps.
[0005] The technical solutions adopted in the embodiments of this application are as follows.

The support is U-shaped. The first limiting member is disposed on one side of the support, and the second limiting member is disposed on the other side of the support. The first limiting member includes a pushing member and a locking block disposed on the end face of the pushing member. The locking block has an inclined surface. The pushing member is disposed on the side wall of the support. The axis of the locking block corresponds to the axis of the second limiting member.

[0011] As a further improvement to the above technical solution: the first block is provided with a baffle that restricts the valve end face.
[0012] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:
[0013] 1. The system utilizes a worm gear drive to rotate, which in turn raises and lowers a threaded rod. This, combined with a hinged connecting rod, synchronously moves all limit plates radially along the slide rail, achieving automatic centering of the valve's outer diameter without manual adjustment. By replacing rubber pads of different thicknesses, it accommodates valve outer diameter tolerances (±10mm and above), allowing for tool-free, rapid adaptation to different valve specifications. The self-locking transmission mechanism after clamping resists machining vibration and impact, preventing valve displacement due to clamping force attenuation. The limit plate's four-corner slider + slide rail design eliminates off-center loading and jamming, ensuring the grippers close vertically and protecting the valve surface. The inclined surface of the first limit component guides the valve to automatically slide into its locking position; initial fixing can be achieved with a single-sided push. Precise control of the valve's axial position within the support groove ensures consistent machining datum (positioning accuracy ±0.1mm). Attached Figure Description

[0018] This application provides an adjustable support platform for valve precision machining, which solves the problems of existing positioning devices for pipeline valve machining, which are mostly simple in structure and single in function. They are not convenient for clamping and positioning valves during pipeline valve machining, cannot automatically clamp valves, and cannot clamp valves of different sizes, resulting in the need to frequently change the clamps.
[0019] The technical solution in this application embodiment is to solve the above problems, and the overall idea is as follows:
[0020] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0021] An adjustable support platform for valve precision machining includes a support 1, a first limiting member 2 at one end of a limiting valve, and a second limiting member 3 at the other end of the limiting valve. The support 1 is U-shaped. The first limiting member 2 is disposed on one side of the support 1, and the second limiting member 3 is disposed on the other side of the support 1. The first limiting member 2 includes a pusher 21 and a locking block 22 disposed on the end face of the pusher 21. The locking block 22 has an inclined surface 221. The pusher 21 is disposed on the side wall of the support 1. The axis of the locking block 22 corresponds to the axis of the second limiting member 3. When the locking block 22 is embedded into one side of the valve until the inclined surface 221 abuts against the valve, one side of the valve is fixed, and the second limiting member 3 fixes the other side of the valve.
[0022] The second limiting component 3 includes a first block 31, a slide rail 32 disposed within the first block 31, a limiting plate 33 that limits the position of the valve, and a moving component 34 that drives the limiting plate 33 to press the valve. A first groove 311 is formed in the first block 31. The moving component 34 is disposed within the first groove 311. A second groove 312 is formed around the first groove 311. The limiting plate 33 slides within the second groove 312. The slide rail 32 is disposed at the four corners of the second groove 312. A slider 331 is disposed at the four corners of the limiting plate 33. The slider 331 is located within the slide rail 32. The moving component 34 drives the limiting plate 33 to slide up and down along the slide rail 32. Several sets of limiting plates 33 are arranged in a circumferential array, and the moving component 34 drives several limiting plates 33 to move synchronously.
[0023] A rubber part 332 is detachable on the limiting plate 33.
[0024] The movable component 34 includes a first rod 35, a second rod 36 sliding on the first rod 35, a third rod 37 that moves the limiting plate 33, and a driving component 38 that drives the first rod 35 to rotate. The first rod 35 rotates at the middle of the first block 31. The second rod 36 is threadedly connected to the first rod 35. One end of the third rod 37 is hinged to the second rod 36, and the other end of the third rod 37 is hinged to the limiting plate 33. The driving component 38 is mounted on the support 1. At least two sets of third rods 37 are hinged to each set of limiting plates 33.
[0025] The driving component 38 includes a worm gear 381, a first plate 382 disposed on the support 1, a worm 383 rotating on the first plate 382, and a rotating component 384 driving the worm 383; the worm gear 381 is disposed on the first rod 35; two sets of the first plates 382 are disposed opposite each other; the rotating component 384 is disposed on the first plate 382; the worm gear 381 meshes with the worm 383; the worm gear 381 and the worm 383 have self-locking properties so that when the limiting plate 33 limits the valve, the first rod 35 will not retract.
[0026] The first piece 31 is equipped with a baffle 313 that restricts the valve end face.
[0027] The worm gear 383 drives rotation, which in turn raises and lowers the threaded rod. This, in turn, synchronously pushes all the limit plates 33 radially along the slide rail 32 via the hinged connecting rod, achieving automatic centering of the valve's outer diameter without manual adjustment. By replacing rubber pads of different thicknesses, it is compatible with valve outer diameter tolerances (±10mm and above), allowing for tool-free and rapid adaptation to different valve specifications. The transmission mechanism is self-locking after clamping, resisting machining vibration and impact, and preventing valve displacement caused by clamping force attenuation. The design of the limit plate 33 with four corner sliders 331 and slide rails 32 eliminates off-center loading and jamming, ensuring the grippers close vertically and protecting the valve surface. The inclined surface 221 of the first limit piece 2 guides the valve to automatically slide into the locking position; initial fixing can be achieved by pushing from one side. Precise control of the valve's axial position within the groove of the support 1 ensures consistent machining datum (positioning accuracy ±0.1mm).
[0028] The valve's outer diameter is automatically aligned by using a worm gear 383 to drive rotation, which in turn raises and lowers the threaded rod. This, in turn, pushes all the limit plates 33 radially along the slide rail 32 via a hinged connecting rod, eliminating the need for manual adjustment.
