Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology, and in particular to a valve body clamp. Background Technology

[0002] Valve body clamps are commonly used devices in industrial manufacturing and maintenance, primarily for fixing and positioning valve bodies for machining or inspection. Traditional valve body clamps typically consist of a combination of components, such as a base plate and clamping assemblies, to achieve effective clamping and positioning of the valve body. However, these traditional clamps have some inconveniences and limitations during operation and adjustment.

[0003] Traditional clamps often lack flexible adjustment mechanisms, resulting in poor adaptability to valve bodies of different specifications and sizes. For example, adjusting the position of the clamping parts may require manual disassembly or adjustment of multiple components, which is not only time-consuming but also inefficient. Furthermore, the interface between fixed and moving parts may have mechanical stability issues, affecting the clamping force and accuracy of the clamp. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a valve body clamp that features adjustable clamping openings based on the size of the valve body.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A valve body clamp includes: a base plate and two clamping assemblies, the two clamping assemblies being mounted on the base plate and arranged opposite to each other. Each clamping assembly includes a fixed plate, a movable plate, a slide table, a first limiting rack, a second limiting rack, and a connecting platform. The fixed plate is fixedly connected to the base plate, the slide table is slidably connected to the base plate, the movable plate is hinged to the slide table and is movable in a first direction, and the fixed plate and the movable plate form a clamping opening for clamping the valve body. The connecting platform is fixed to the base plate, the first limiting rack is fixed to the movable plate, and the second limiting rack is fixed to the connecting platform. The first limiting rack and the second limiting rack can mesh to restrict the movement of the movable plate.

[0007] On the valve body clamp described above, the fixed plate is provided with a first inclined surface, and the movable plate is provided with a second inclined surface, the first inclined surface and the second inclined surface forming a clamping opening.

[0008] On the valve body fixture described above, the connecting platform has a support surface facing the direction of the moving plate, and the second limiting rack is fixed on the support surface. When the first limiting rack and the second limiting rack are fully engaged, the support surface is parallel to the surface of the moving plate.

[0009] On the valve body fixture mentioned above, a guide rail is fixed on the base plate, and the slide table is slidably connected to the guide rail.

[0010] On the valve body fixture mentioned above, the length of the second limiting rack is greater than the length of the first limiting rack.

[0011] Compared with the prior art, this application has the following advantages:

[0012] By introducing a slidably connected slide and a hinged moving plate, the clamp can be adjusted more flexibly to accommodate valve bodies of different sizes and shapes. This design allows for quick and easy adjustments, improving the clamp's versatility and practicality. Utilizing the engagement mechanism of the first and second limiting racks, the clamp provides precise positional restraint during adjustment, preventing displacement during use. Adjusting the moving plate's position simply requires swinging it towards the fixed plate, disengaging the first and second limiting racks, and then allowing it to move freely.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0027] like Figures 1 to 3 As shown, a valve body clamp includes: a base plate 2 and two clamping assemblies. The two clamping assemblies are mounted on the base plate 2 and arranged opposite to each other. Each clamping assembly includes a fixed plate 3, a movable plate 4, a slide table 5, a first limiting rack 6, a second limiting rack 7, and a connecting platform 8. The fixed plate 3 is fixedly connected to the base plate 2, the slide table 5 is slidably connected to the base plate 2, the movable plate 4 is hinged to the slide table 5 and can move along a first direction RL, and the fixed plate 3 and the movable plate 4 form a clamping opening 9 for clamping the valve body. The connecting platform 8 is fixed to the base plate 2, the first limiting rack 6 is fixed to the movable plate 4, and the second limiting rack 7 is fixed to the connecting platform 8. The first limiting rack 6 and the second limiting rack 7 can mesh to restrict the movement of the movable plate 4.

[0028] In this application, the two clamping components can stably support the limiting valve body, and the size of the clamping opening 9 on the clamping components can be adjusted when dealing with valve bodies of different sizes. The fixed plate 3 is fixedly connected to the base plate 2, providing a stable support point. The movable plate 4 is rotatably connected to the slide table 5 via a shaft and can move along the first direction RL. This design allows the movable plate 4 to adjust its position according to the size of the valve body to accommodate valve bodies of different sizes.

[0029] When adjusting the position of the movable plate 4, simply swing the movable plate 4 towards the fixed plate 3, allowing the first limiting rack 6 and the second limiting rack 7 to disengage and move freely, thus adjusting to the appropriate position. Then, swing the movable plate 4 towards the connecting platform 8, and the first limiting rack 6 and the second limiting rack 7 will automatically abut and engage for limiting. Afterwards, when the valve body presses against the movable plate 4, the first limiting rack 6 and the second limiting rack 7 will be firmly locked together, preventing the movable plate 4 from moving.

[0030] Specifically, the fixed plate 3 is provided with a first inclined surface 31, and the movable plate 4 is provided with a second inclined surface 41. The first inclined surface 31 and the second inclined surface 41 form a clamping opening 9.

[0031] Automatic centering: The clamping opening 9 formed by two inclined surfaces automatically centers the valve body when placed, ensuring that the valve body is stably centered and preventing displacement. The inclined surface design allows the size of the clamping opening 9 to be flexibly adjusted to accommodate valve bodies of different sizes, improving the versatility of the equipment.

[0032] Specifically, the connecting platform 8 has a support surface facing the moving plate 4, and the second limiting rack 7 is fixed on the support surface. When the first limiting rack 6 and the second limiting rack 7 are fully engaged, the support surface is parallel to the surface of the moving plate 4.

[0033] The support surface is parallel to the surface of the movable plate 4, so that when the limiting rack is fully engaged, the movable plate 4 can obtain more stable support, avoid shaking, and improve the stability of the overall structure.

[0034] Specifically, a guide rail 10 is fixed on the base plate 2, and the slide table 5 is slidably connected to the guide rail 10.

[0035] The guide rail 10 provides a stable, straight path of movement, enabling the slide 5 to move precisely along a predetermined direction, thereby ensuring that the moving plate 4 can be accurately adjusted to the desired position.

[0036] Specifically, the length of the second limiting rack 7 is greater than the length of the first limiting rack 6.

[0037] The longer second limiting rack 7 can provide more meshing teeth, thereby enhancing the limiting effect and making the moving plate 4 more stable and secure when it is in a fixed position. Even after the moving plate 4 has moved, it can still fully mesh the first limiting rack 6 and the second limiting rack 7, ensuring that the moving plate 4 is not easily displaced during the clamping process and improving the overall clamping stability.

[0038] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture, as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.

[0039] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Meanwhile, the meaning of "and / or" throughout the text includes three solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.
