Description

Technical Field

[0001] This utility model relates to the field of pneumatic valve cylinder disassembly technology, and more specifically to a pneumatic valve cylinder disassembly device. Background Technology

[0002] The working principle of a pneumatic valve is to rotate the valve core to open or close the valve. Pneumatic ball valves offer reliable sealing, simple structure, and easy maintenance. The sealing surface and the ball are constantly in a closed state, making them less susceptible to erosion by the medium, and they are widely used in various industries. Pneumatic valves utilize compressed air to drive the pneumatic piston, gears, and other mechanical components within the actuator, transmitting force to related parts, which in turn actuate the valve core or valve plate, thereby opening, closing, or regulating the valve to control the fluid medium. Their structure is simple, mainly composed of basic components such as the valve body, valve cover, valve stem, and valve core, without complex transmission mechanisms. They offer fast response speeds; the compressibility and fluidity of compressed air allow for rapid power transmission, enabling quick opening and closing of the valve. They also offer high control precision; by controlling the pressure, flow rate, and direction of the compressed air, the valve opening can be precisely controlled. Semiconductor manufacturing processes require extremely high precision in controlling process parameters. For example, in the photolithography process, it is necessary to precisely control the coating thickness of the photoresist and the flow rate of the developer. Therefore, pneumatic valves are used for control, which can achieve precise adjustment of fluid flow through precise air pressure control, thus meeting the high precision requirements of semiconductor manufacturing processes.

[0003] Currently, the maintenance of pneumatic valves requires disassembling the cylinder, removing the disc spring, and then inspecting the internal structure. To facilitate cylinder disassembly, a disassembly device is used, such as the pneumatic valve cylinder disassembly and assembly tool disclosed in prior art CN221755927U.

[0004] However, the existing technology described above still has the following problems in use: the pneumatic valve cylinder is heavy, and during disassembly and handling by hand, the cylinder is very easy to fall off or be damaged by impact. This not only makes the operation time-consuming and laborious, but also greatly reduces the efficiency of disassembly and maintenance. Based on this, the present invention provides a pneumatic valve cylinder disassembly device. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides a pneumatic valve cylinder disassembly device. The device uses two guide rails and two sets of clamps to hold the pneumatic valve cylinder, facilitating the separation of the pneumatic valve cylinder and the pneumatic valve ball valve by the operator. Simultaneously, positioning pins limit the left and right end caps of the pneumatic valve cylinder, preventing damage caused by the springs inside the cylinder pushing the end caps to move rapidly. The guide rails and clamps then automatically reset, achieving the separation of the pneumatic valve cylinder. This significantly improves the disassembly efficiency of the pneumatic valve cylinder, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pneumatic valve cylinder disassembly device, comprising a top plate, with support plates fixedly provided on both sides of the bottom of the top plate, and a linear module fixedly provided on the side of the two support plates that are close to each other. A guide rail is fixedly provided on the top of the linear module, and two clamping plates for clamping the pneumatic valve cylinder are provided above the guide rail. The two clamping plates are driven by a drive mechanism. Through holes are provided on both support plates, and positioning pins pass through the through holes. Positioning grooves adapted to the pneumatic valve cylinder are provided on the side of the two positioning pins that are close to each other.

[0007] In a preferred embodiment, the driving mechanism includes a lead screw rotatably disposed inside a guide rail. Two nut blocks are threadedly connected to the guide rail. The threads of the two nut blocks and the lead screw have opposite directions, causing the two nut blocks to move in opposite directions. The two nut blocks are detachably connected to two clamping plates respectively. The two nut blocks can be driven to rotate simultaneously by a single lead screw, thereby enabling synchronous adjustment of the positions of the two clamping plates.

[0008] In a preferred embodiment, a motor is fixedly embedded at the rear end of both guide rails. The front end of the motor output shaft passes through the guide rail and is fixed to the rear end of the lead screw. The motor drives the lead screw to rotate automatically, thereby improving disassembly efficiency.

[0009] In a preferred embodiment, each of the two support plates has a storage groove at its front end, and a spring pin is fixed inside the storage groove. Each of the two positioning posts has two slots that are adapted to the spring pins at its front end. The rear end of the spring pin is inserted into the slot, and the positioning post is fixed by the spring pin, which makes it easy for the operator to quickly adjust the position of the positioning post.

[0010] In a preferred embodiment, rubber pads are fixedly bonded to the outer walls of the two guide rails and the outer wall of each clamping plate. The rubber pads have anti-slip textures on their surfaces and are made of soft material. When the guide rails and clamping plates come into contact with the pneumatic valve cylinder, the rubber pads can provide cushioning and protection, preventing scratches on the surface of the pneumatic valve cylinder. At the same time, the anti-slip textures can improve stability to a certain extent when the guide rails and clamping plates firmly clamp the pneumatic valve cylinder.

[0011] In a preferred embodiment, a handle is fixedly provided on the top of the top plate, and multiple fixing holes are machined on the top plate to facilitate the installation of the top plate on external equipment.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] This invention uses two guide rails and two sets of clamps to hold the pneumatic valve cylinder, making it easy for operators to separate the pneumatic valve cylinder and the pneumatic valve ball valve. At the same time, the positioning pins limit the left and right end covers of the pneumatic valve cylinder, which can prevent the spring inside the pneumatic valve cylinder from pushing the left and right end covers to move rapidly and causing damage. Afterwards, the guide rails and clamps are used to automatically reset, so as to realize the separation of the pneumatic valve cylinder, which greatly improves the disassembly efficiency of the pneumatic valve cylinder.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Refer to the instruction manual appendix Figures 1-5This utility model provides a pneumatic valve cylinder disassembly device, including a top plate 1. Support plates 2 are fixedly mounted on both sides of the bottom of the top plate 1. A linear module 3 is fixedly mounted on one side of the two support plates 2 that are close to each other. A guide rail 4 is fixedly mounted on the top of the linear module 3. Two clamping plates 5 for holding the pneumatic valve cylinder are mounted above the guide rail 4. The two clamping plates 5 are driven by a drive mechanism 6. Specifically, the drive mechanism 6 includes a lead screw 61, which is rotatably mounted inside the guide rail 4. Two nut blocks 62 are threadedly connected to the guide rail 4. The threads of the two nut blocks 62 and the lead screw 61 have opposite directions, causing the two nut blocks 62 to move in opposite directions. The two nut blocks 62 are detachably connected to the two clamping plates 5. A motor 63 is fixedly embedded at the rear end of each of the two guide rails 4. The front end of the output shaft of the motor 63 passes through the guide rail 4 and is fixed to the rear end of the lead screw 61. The motor 63 drives the lead screw 61 to rotate automatically, thereby improving disassembly efficiency.

[0023] Both support plates 2 have through holes 7, and positioning posts 8 pass through the through holes 7. The two positioning posts 8 have positioning grooves 9 on the side close to each other, which are adapted to the pneumatic valve cylinder.

[0024] Both support plates 2 have a storage slot 10 at their front ends. A spring pin 11 is fixed inside the storage slot 10. Both positioning posts 8 have two slots 12 that are adapted to the spring pin 11 at their front ends. The rear end of the spring pin 11 is inserted into the slot 12. The positioning post 8 is fixed by the spring pin 11, which makes it easy for the operator to quickly adjust the position of the positioning post 8.

[0025] In actual use, the operator first inserts the two support plates 2 at the bottom of the top plate 1 into the bottom of the pneumatic valve cylinder. Then, the motor on the linear module 3 drives the lead screw to rotate. The lead screw drives the guide rail 4 to move through the nut block, so that the guide rail 4 abuts against the pneumatic valve cylinder. Then, the motor 63 drives the lead screw 61 to rotate. The two nut blocks 62 on the lead screw 61 move synchronously, and drive the clamping plate 5 to abut against the outer wall of the pneumatic valve cylinder. This fixes the entire disassembly device on the pneumatic valve cylinder. After the operator separates the pneumatic valve cylinder from the ball valve, the disassembly can be performed using... The top plate 1 is used to remove the pneumatic valve cylinder. When it is necessary to disassemble the internal structure of the pneumatic valve cylinder, the operator first loosens the bolts on the left end cover of the pneumatic valve cylinder, then pulls the spring pin 11 to move the pin out of the slot 12, and pushes the positioning pin 8 and the left end cover by hand to prevent the spring in the pneumatic valve cylinder from pushing the left end cover to move quickly and causing damage. Then, the right end cover is disassembled according to the above operation steps. After the left and right end covers are disassembled, the disassembly device can be removed from the pneumatic valve cylinder, and the internal structure of the pneumatic valve cylinder can be inspected.

[0026] like Figures 4-5As shown, rubber pads 13 are fixedly bonded to the outer walls of the two guide rails 4 and the outer walls of each clamping plate 5. The surface of the rubber pads 13 is processed with anti-slip texture. The rubber pads 13 are made of soft material. When the guide rails 4 and clamping plates 5 come into contact with the pneumatic valve cylinder, the rubber pads 13 can play a buffering and protective role to avoid scratches on the surface of the pneumatic valve cylinder. At the same time, the anti-slip texture can improve the stability to a certain extent when the guide rails 4 and clamping plates 5 firmly clamp the pneumatic valve cylinder.

[0027] A handle 14 is fixedly provided on the top of the top plate 1, and multiple fixing holes 15 are machined on the top plate 1 to facilitate the installation of the top plate 1 on external equipment.

[0028] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
