Description

Technical Field

[0001] This utility model relates to the field of air valve processing technology, and in particular to an air valve processing fixing device. Background Technology

[0002] Inflatable valve manufacturing is the process of turning, milling, drilling, tapping, and assembling raw materials of metal and plastic to create a valve device for controlling the inflow and outflow of gas. Its main structure typically includes a valve body, valve core, sealing ring, spring, and interface components. The working principle is to drive the valve core manually or automatically, changing its relative position with the valve seat, thereby realizing the functions of inflation, sealing and pressure maintenance, and deflation. Inflatable valves are widely used in automobile and bicycle tires, balls, inflatable products, medical equipment, pneumatic tools, and various pressure vessels, providing these devices with safe and reliable inflation and pressure maintenance solutions.

[0003] The inflation valve requires a fixing device during processing. Existing fixing devices use V-blocks and locating pins to precisely position the workpiece, and then use manual, pneumatic, and hydraulic methods to drive the pressure block to reliably clamp it, ensuring stability during drilling, tapping, and turning processes, thereby guaranteeing dimensional accuracy and consistency. However, the existing fixing device structure is too complex, and the pneumatic and hydraulic clamping methods have excessive clamping force, which can damage the inflation valve and reduce the practicality of the device. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a gas valve processing and fixing device, which aims to improve the problem that the clamping mechanism in the prior art is prone to damaging the gas valve.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an inflation valve processing and fixing device, comprising an operating cylinder, a pressing hole on the upper left side of the outer wall of the operating cylinder, a rotating hole on the upper middle part of the outer wall of the operating cylinder, an inner shaft rotatably connected to the inner wall of the rotating hole, a half gear fixedly connected to the middle of the outer wall of the inner shaft, an operating rod fixedly connected to the outer wall of the half gear, a rack meshing with the outer wall of the half gear, a rotating column rotatably connected to the bottom end of the rack, a limiting groove on the outer wall of the rotating column, a fixing rod slidably connected to the inner wall of the limiting groove, a squeezing column fixedly connected to the bottom of the rotating column, a suction cup fixedly connected to the bottom end of the squeezing column, and an auxiliary positioning mechanism provided at the bottom of the suction cup for auxiliary positioning of the inflation valve.

[0006] As a further description of the above technical solution: The auxiliary positioning mechanism includes a second fixed plate. A telescopic hole is provided in the lower middle part of the outer wall of the second fixed plate. A tension rod is slidably connected to the inner wall of the telescopic hole. A handle is fixedly connected to the front end of the tension rod. A spring is slidably connected to the outer wall of the tension rod. A compression ring is fixedly connected to the rear side of the outer wall of the tension rod. A positioning block is fixedly connected to the rear end of the tension rod. A limit cylinder is slidably connected to the outer wall of the compression ring. A limit ring is fixedly connected to the rear end of the limit cylinder.

[0007] As a further description of the above technical solution: A fixing plate is fixedly connected to the top of the operating cylinder, and a connecting plate is fixedly connected to the bottom right side of the fixing plate.

[0008] As a further description of the above technical solution: The bottom end of the connecting plate is fixedly connected to a bearing plate, and the inner wall of the bearing plate is provided with a rotating groove.

[0009] As a further description of the above technical solution: A shelf is rotatably connected to the inner wall of the rotating groove, and a rotating rod is fixedly connected to the bottom center of the shelf.

[0010] As a further description of the above technical solution: A bevel gear one is fixedly connected to the middle of the outer wall of the rotating rod, and a bevel gear two is meshed with the outer wall of the bevel gear one.

[0011] As a further description of the above technical solution: The other end of the bevel gear is fixedly connected to a handle, and the bottom end of the rotating rod is rotatably connected to a base plate.

[0012] As a further description of the above technical solution: A protective cylinder is fixedly connected to the top of the base plate, and the middle of the inner wall of the protective cylinder is rotatably connected to the outer wall of the second bevel gear.

[0013] This utility model has the following beneficial effects: 1. In this utility model, when the device is working normally, first place the inflation valve in the middle of the placement plate, then push the operating lever upward under the limit of the pressing hole, drive the half gear to rotate clockwise around the inner shaft, so that the rack moves downward, and then press the rotating column downward. Under the limit of the fixed rod, the limiting groove on the outer wall of the rotating column drives the rotating column to rotate and press downward, thereby allowing the pressing column to drive the suction cup to move downward together, and finally complete the secure fixation of the inflation valve. The clamping force can be adjusted to improve the practicality of the device. 2. In this utility model, when the device is working, it needs to be positioned before the inflation valve is placed. First, pull the handle two outward so that it drives the tension rod to move outward under the limit of the telescopic hole, so that the compression ring squeezes the spring inside the limiting cylinder. At this time, place the inflation valve on the shelf, release the handle two, and the spring rebounds to drive the tension rod to move inward, so that the positioning block clamps it inward, thereby fixing the inflation valve and improving the practicality of the device.

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.

[0017] Please see the appendix Figure 2 and attached Figure 3An embodiment of this utility model provides an inflation valve processing and fixing device, including an operating cylinder 1. A pressing hole 3 is provided on the upper left side of the outer wall of the operating cylinder 1. A rotating hole 4 is provided on the upper middle part of the outer wall of the operating cylinder 1. An inner shaft 5 is rotatably connected to the inner wall of the rotating hole 4. A half gear 7 is fixedly connected to the middle of the outer wall of the inner shaft 5. An operating rod 6 is fixedly connected to the outer wall of the half gear 7. A rack 8 is meshed with the outer wall of the half gear 7. A rotating column 9 is rotatably connected to the bottom end of the rack 8. A limiting groove 10 is provided on the outer wall of the rotating column 9. A fixing rod 11 is slidably connected to the inner wall of the limiting groove 10. A squeezing column 12 is fixedly connected to the bottom of the rotating column 9. A suction cup 13 is fixedly connected to the bottom end of the squeezing column 12. An auxiliary positioning mechanism 2 is provided at the bottom of the suction cup 13. The auxiliary positioning mechanism 2 is used for auxiliary positioning of the inflation valve. Specifically, the operating cylinder 1 is the basic frame of the device. The pressing hole 3 on the upper left side of its outer wall provides a limit for the movement of the operating rod 6. The rotating hole 4 in the upper middle part of the outer wall is used to install the inner shaft 5. The inner shaft 5 can rotate inside the rotating hole 4, and the half gear 7 fixed in the middle of the outer wall of the inner shaft 5 rotates synchronously with it. The operating rod 6 is fixed to the outer wall of the half gear 7. Moving the operating rod 6 can drive the half gear 7 to rotate around the inner shaft 5. The half gear 7 meshes with the rack 8 and can drive the rack 8 to move up and down by rotating itself. The bottom end of the rack 8 is rotatably connected to the rotating column 9, which can drive the rotating column 9 to move. The limiting groove 10 on the outer wall of the rotating column 9 is slidably connected to the fixing rod 11. The fixing rod 11 can limit the movement trajectory of the rotating column 9, so that the rotating column 9 can stably drive the bottom fixed extrusion column 12 to move. The suction cup 13 fixed at the bottom of the extrusion column 12 is used to directly contact and fix the inflation valve. The auxiliary positioning mechanism 2 at the bottom of the suction cup 13 can assist in positioning the inflation valve before the suction cup 13 is fixed, thereby improving the fixing accuracy.

[0018] Please see the appendix Figure 3 and attached Figure 4 The auxiliary positioning mechanism 2 includes a fixed plate 201. A telescopic hole 202 is provided in the lower middle part of the outer wall of the fixed plate 201. A tension rod 203 is slidably connected to the inner wall of the telescopic hole 202. A handle 204 is fixedly connected to the front end of the tension rod 203. A spring 205 is slidably connected to the outer wall of the tension rod 203. A compression ring 206 is fixedly connected to the rear side of the outer wall of the tension rod 203. A positioning block 207 is fixedly connected to the rear end of the tension rod 203. A limit cylinder 208 is slidably connected to the outer wall of the compression ring 206. A limit ring 209 is fixedly connected to the rear end of the limit cylinder 208. Specifically, in the auxiliary positioning mechanism 2, the fixed plate 201 is the basic installation carrier. The telescopic hole 202 in the lower middle part of its outer wall provides sliding support for the tension rod 203, allowing the tension rod 203 to move back and forth along the telescopic hole 202. The handle 204 at the front end of the tension rod 203 is convenient for the operator to manually pull, driving the tension rod 203 to move. The compression ring 206 fixed on the rear side of the outer wall cooperates with the spring 205 slidably connected to the outer wall, and the compression ring 206 can slide on the inner wall of the limiting cylinder 208. The limiting cylinder 208 can limit the range of motion of the compression ring 206 and the spring 205 to prevent displacement. The positioning block 207 at the rear end of the tension rod 203 moves with the tension rod 203 to achieve clamping and positioning of the inflation valve. The limiting ring 209 at the rear end of the limiting cylinder 208 plays a limiting role to prevent the tension rod 203 from moving excessively and causing the parts to fall off.

[0019] Please see the appendix Figure 1 and attached Figure 5 The top of the operating cylinder 1 is fixedly connected to a fixing plate 14, the bottom right side of the fixing plate 14 is fixedly connected to a connecting plate 15, the bottom end of the connecting plate 15 is fixedly connected to a bearing plate 16, the inner wall of the bearing plate 16 is provided with a rotating groove 17, the inner wall of the rotating groove 17 is rotatably connected to a placement plate 18, and the bottom middle of the placement plate 18 is fixedly connected to a rotating rod 19. Specifically, the fixed plate 14 fixed at the top of the operating cylinder 1 is a connecting carrier, and the connecting plate 15 fixed at its bottom right side is used to connect the fixed plate 14 and the bearing plate 16, playing a supporting and connecting role. The bearing plate 16 fixed at the bottom of the connecting plate 15 is the mounting base of the placement plate 18. The rotating groove 17 opened in its inner wall provides rotation space for the placement plate 18, so that the placement plate 18 can rotate flexibly in the inner wall of the rotating groove 17. The placement plate 18 is used to place the inflation valve to be fixed. The rotating rod 19 fixed in the middle of its bottom end can assist the rotation of the placement plate 18, making it convenient to adjust the processing angle of the inflation valve and improve the flexibility of the device.

[0020] Please see the appendix Figure 1 and attached Figure 5 A bevel gear 20 is fixedly connected to the middle of the outer wall of the rotating rod 19. A bevel gear 21 is meshed with the outer wall of the bevel gear 20. A handle 22 is fixedly connected to the other end of the bevel gear 21. A base plate 23 is rotatably connected to the bottom end of the rotating rod 19. A protective cylinder 24 is fixedly connected to the top of the base plate 23. The middle of the inner wall of the protective cylinder 24 is rotatably connected to the outer wall of the bevel gear 21. Specifically, the bevel gear 20 fixed in the middle of the outer wall of the rotating rod 19 meshes with the bevel gear 21 to form a transmission connection. Rotating the handle 22 fixed at the other end of the bevel gear 21 can drive the bevel gear 20 to rotate through gear meshing, thereby causing the rotating rod 19 to rotate synchronously and realize the angle adjustment of the shelf 18. The bottom end of the rotating rod 19 is rotatably connected to the base plate 23, which provides stable support for the rotating rod 19. The protective cylinder 24 fixed at the top of the base plate 23 is rotatably connected to the outer wall of the bevel gear 21 in the middle of its inner wall, which not only provides a rotation fulcrum for the bevel gear 21, but also protects the internal gear structure and ensures stable transmission.

[0021] Working principle: When the device is working normally, first place the inflation valve in the middle of the placement plate 18, then push the operating rod 6 upward under the limit of the pressing hole 3, thereby driving the half gear 7 to rotate clockwise around the inner shaft 5, which in turn causes the rack 8 to move downward, and then press the rotating column 9 downward. Under the limit of the fixing rod 11, the limiting groove 10 on the outer wall of the rotating column 9 drives the rotating column 9 to rotate and press downward, thereby causing the pressing column 12 to drive the suction cup 13 to move downward together, finally completing the secure fixation of the inflation valve. The clamping force can be adjusted, which improves the practicality of the device. Before inserting the inflation valve, it needs to be positioned. First, pull the handle 204 outward, which will cause the tension rod 203 to move outward under the limit of the telescopic hole 202. This will cause the compression ring 206 to compress the spring 205 inside the limiting cylinder 208. Then, place the inflation valve on the shelf 18 and release the handle 204. Under the rebound of the spring 205, the tension rod 203 will move inward, which will cause the positioning block 207 to clamp inward, thereby fixing the inflation valve and improving the practicality of the device.
