Description

Technical Field

[0001] This invention relates to the field of valve plate processing technology, and more particularly to a fixing device for valve plate processing. Background Technology

[0002] However, valves are key components in fluid transport systems. Inside a valve, a valve plate is mounted via a valve shaft. The valve plate rotates around the valve shaft to achieve opening, closing, or regulation. The valve plate and valve seat fit tightly together to form a reliable seal, preventing media leakage. Types of valve plates include: flat valve plates, wedge valve plates, ball valve plates, butterfly valve plates, and cone valve plates.

[0003] Currently, in the valve plate production process, to meet the installation requirements of the valve seat and its components, radial through holes are typically machined after the main body of the valve plate is completed and before assembly. However, existing valve plate machining fixtures suffer from insufficient adaptability: their fixtures mostly adopt a rigid structure design, lacking adjustability and making it difficult to adapt to the clamping requirements of valve plates of different specifications. Due to the diverse specifications of valve plate products, traditional fixed fixtures are prone to positioning deviations and uneven clamping forces during clamping, directly leading to decreased machining accuracy, reduced production efficiency, and even the risk of product scrapping.

[0004] In summary, the existing valve plate processing fixing devices suffer from poor adaptability and low production efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a fixing device for valve plate processing, which can solve the problems of poor adaptability and low production efficiency of the fixing devices for valve plate processing in the prior art.

[0006] To achieve the above objectives, according to an embodiment of the first aspect of this utility model, a fixing device for processing valve plates is provided, including a fixing seat, wherein a fixing groove is provided on the surface of the fixing seat for placing and fixing the valve plate;

[0007] Also includes:

[0008] A fixed clamping mechanism includes a pair of sliding rods disposed in a fixed groove and clamping seat 1 and clamping seat 2 respectively disposed on the inner sides of the two sliding rods. The inner sides of clamping seat 1 and clamping seat 2 are provided with placement notches. A mold sleeve is disposed in each placement notch. A mounting rod is fixedly installed in the port of each mold sleeve. Electric cylinders are fixedly installed on both sides of the fixed seat. The rod of each electric cylinder passes through the fixed seat and is connected to the back of each sliding rod.

[0009] A further improvement is that the mold sleeve fits into each placement notch, and each mold sleeve is made of rubber.

[0010] A further improvement is that limit grooves are provided on the inner walls of both sides of the port of the fixed seat, and guide blocks are fixedly installed on both sides of the clamping seat one and clamping seat two, respectively slidingly in the limit grooves through the guide blocks on both sides.

[0011] A further improvement is that a buffer spring is installed at each end of the outer side of the first and second clamps, and the other end of the buffer spring is fixedly connected to the inner side of the two slide rods. At each end of the outer side of the first and second clamps, a guide post is fixedly installed next to each buffer spring. The inner side of the two slide rods is provided with a guide groove at the position corresponding to each guide post, and each guide post is inserted into the guide groove.

[0012] A further improvement is that it also includes a connecting component, which includes an adsorption magnetic plate one fixedly installed on the inner wall of each placement notch and an adsorption magnetic plate two fixedly installed on the bottom surface of the two mold sleeves and adsorbed to the adsorption magnetic plate one.

[0013] A further improvement is that each of the first adsorption magnetic plates is provided with a positioning block on its surface, and each positioning block and the first adsorption magnetic plate are integrally formed. The bottom surface of the second adsorption magnetic plate is provided with a positioning groove for mounting with the positioning block.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) This utility model involves installing two mold sleeves into the placement notches of clamping base one and clamping base two, respectively. During installation, the mutual adhesion between the adsorption magnetic plate two on the bottom surface of clamping base one and clamping base two and the adsorption magnetic plate one in the placement notch is utilized to achieve rapid positioning. At the same time, the positioning block on the bottom surface of the adsorption magnetic plate two will be inserted into the positioning groove of the adsorption magnetic plate one, which plays a limiting role. This design makes the mold sleeves easy and efficient to assemble and disassemble, and can quickly adapt to the clamping requirements of valve plates of different specifications.

[0016] (2) After the mold sleeve is installed, the valve plate is clamped. First, one side of the valve plate is clamped onto the connecting rod inside the port of one mold sleeve. Then, the electric cylinders on both sides are started simultaneously. The electric cylinder on one side drives the slide rod and clamp seat one, and the electric cylinder on the other side drives the slide rod and clamp seat two, until the other side of the valve plate is clamped onto the connecting rod inside the port of another mold sleeve, thereby realizing the fixed clamping of valve plates of different specifications. In addition, in order to improve the clamping quality and production efficiency, the equipment is equipped with a guide post and a buffer spring on both sides of the back of clamp seat one and clamp seat two, and each mold sleeve is made of rubber. This design can effectively avoid positioning deviation during the clamping process, and at the same time prevent the valve plate from being damaged due to excessive clamping force, thereby improving the processing accuracy of the valve plate and the overall production efficiency.

[0025] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] like Figures 1 to 4 As shown, a valve plate processing fixing device includes a fixing seat 2, and a fixing groove 21 is formed on the surface of the fixing seat 2;

[0027] The fixed clamping mechanism 1 includes a pair of slide rods 11 disposed in the fixed groove 21 and clamping seat 13 and clamping seat 24 disposed on the inner side of the two slide rods 11 respectively. The inner side of clamping seat 13 and clamping seat 2 14 are provided with placement notches 102. Each placement notch 102 is provided with a mold sleeve 17. Each mold sleeve 17 has a connecting rod 18 fixedly installed in the port of each mold sleeve 17. Electric cylinders 12 are fixedly installed on both sides of the fixed seat 2. The rod of each electric cylinder 12 passes through the fixed seat 2 and is connected to the back of each slide rod 11.

[0028] It should be noted that each mold sleeve 17 fits into each placement notch 102, and each mold sleeve 17 is made of rubber to protect the two sides of the valve plate; each electric cylinder 12 is a commercially available product for installation and debugging.

[0029] As a preferred embodiment, the inner walls on both sides of the port of the fixed seat 2 are provided with limiting grooves 101. Guide blocks are fixedly installed on both sides of the clamp 13 and clamp 2 14. The clamp 13 and clamp 2 14 are slidably disposed in the limiting grooves 101 through the guide blocks on both sides, for limiting the sliding of the clamp 13 and clamp 2 14.

[0030] As a preferred embodiment, a buffer spring 15 is installed at each end of the outer side of clamp 13 and clamp 2 14. The other end of the buffer spring 15 is fixedly connected to the inner side of the two slide rods 11. At each end of the outer side of clamp 13 and clamp 2 14, a guide post 16 is fixedly installed next to each buffer spring 15. The inner side of the two slide rods 11 is provided with a guide groove 103 at the position corresponding to each guide post 16. Each guide post 16 is inserted into the guide groove 103 to guide the movement of clamp 13 and clamp 2 14. At the same time, the buffer spring 15 plays a buffering and shock absorption role.

[0031] like Figure 4 As shown in this embodiment, another implementation scheme is also provided, as detailed below:

[0032] It also includes a connecting component 3, which includes an adsorption magnetic plate 31 fixedly installed on the inner wall of each placement notch 102 and an adsorption magnetic plate 32 fixedly installed on the bottom surface of the two mold sleeves 17 and adsorbing the adsorption magnetic plate 31. The mold sleeves 17 are respectively installed into the placement notches 102 of the clamps 13 and 24, and the adsorption magnetic plate 32 on the bottom surface of the clamps 13 and 24 and the adsorption magnetic plate 31 in the placement notch 102 are mutually adhesive to achieve rapid positioning.

[0033] As a preferred embodiment, each adsorption magnetic plate 31 has a positioning block 33 on its surface, and each positioning block 33 and adsorption magnetic plate 31 are integrally formed. The bottom surface of the adsorption magnetic plate 32 has a positioning groove 3 for mounting with the positioning block 33. During installation, the positioning block 33 on the bottom surface of the adsorption magnetic plate 32 will engage with the positioning groove 34 of the adsorption magnetic plate 31, thus providing a limiting function. This design makes the assembly and disassembly of the mold sleeve 17 convenient and efficient, and can quickly adapt to the clamping requirements of valve plates of different specifications.

[0034] like Figures 1 to 4As shown in this embodiment, it should also be noted that the actual dimensions and shapes of the components in the application document are selected and installed according to the actual needs on site. In this embodiment, the valve plate is square; if it were circular, the mold sleeve 17 would be selected accordingly to match the shape. Furthermore, it should be noted that this application document only addresses the shortcomings of poor adaptability and low production efficiency in the existing valve plate processing fixing device, and does not involve other aspects. The working principle of this valve plate processing fixing device is described below:

[0035] When using this new solution, the on-site staff first selects a pair of suitable mold sleeves 17. Then, the pair of mold sleeves 17 are installed into the placement notches 102 of clamping base one 13 and clamping base two 14, respectively. During installation, the mutual adhesion between the adsorption magnetic plate two 32 on the bottom surface of clamping base one 13 and clamping base two 14 and the adsorption magnetic plate one 31 in the placement notch 102 achieves rapid positioning. Simultaneously, the positioning block 33 on the bottom surface of the adsorption magnetic plate two 32 engages with the positioning groove 34 of the adsorption magnetic plate one 31, serving as a limiting function. This design makes the mold sleeves 17 easy and efficient to assemble and disassemble, and can quickly adapt to the clamping requirements of valve plates of different specifications.

[0036] After the mold sleeve 17 is installed, the valve plate clamping begins. First, one side of the valve plate is clamped onto the latching rod 18 inside the port of one mold sleeve 17. Then, the electric cylinders 12 on both sides are activated simultaneously. One electric cylinder 12 drives the sliding rod 11 and clamping seat one 13, while the other electric cylinder 12 drives the sliding rod 11 and clamping seat two 14, until the other side of the valve plate is clamped onto the latching rod 18 inside the port of another mold sleeve 17, thus achieving the fixed clamping of valve plates of different specifications. Furthermore, to improve clamping quality and production efficiency, the equipment has a guide post 16 and a buffer spring 15 on each side of the back of clamping seat one 13 and clamping seat two 14, and each mold sleeve 17 is made of rubber. This design effectively avoids positioning deviations during clamping and prevents damage to the valve plate due to excessive clamping force, thereby improving the processing accuracy of the valve plate and overall production efficiency.

[0037] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
