Description

Technical Field

[0001] This utility model relates to the field of automotive braking system assembly technology, and in particular to a product inflation self-clamping sealing device. Background Technology

[0002] The valve timing sealing device is a necessary component in automotive braking system assembly. Existing valve timing sealing devices primarily rely on valve timing bolts for tightening, which is cumbersome to operate. Frequent tooling is required to disassemble and assemble the valve head during loading, unloading, and model changes, resulting in low efficiency. Furthermore, valve timing bolts, washers, and other components need regular replacement, and bolt tightening can easily cause scratches and impacts on the product, affecting product quality. The connectors used are multi-lobed threaded quick connectors, which have a short lifespan, high maintenance costs, and are bulky, making them unsuitable for some confined spaces. While clamping uses a single-sided thrust mechanism, this lacks a limiting mechanism, leading to unilateral force during assembly, which can cause deformation and render the product unusable. Utility Model Content

[0003] In view of this, the purpose of this invention is to provide a product inflation self-clamping sealing device and its usage method to solve the problems of high product scrap rate due to bumps and scratches, cumbersome operation, and high maintenance costs.

[0004] To achieve the above objectives, this utility model provides a product inflation self-clamping sealing device, including a base with mounting seats at both ends. A clamping mechanism is provided in one mounting seat, and a clamping inflation mechanism is provided in the other mounting seat. An air passage is provided in the base, and an air chamber is provided in the mounting seats. The air passage and the air chamber are connected. Inflation into the air chamber through the air passage drives the clamping mechanism and the clamping inflation mechanism to move towards each other to clamp the product. The clamping inflation mechanism inflates when clamping the product.

[0005] A further improvement is that the clamping mechanism includes a first piston, which is slidably disposed in the air chamber of a mounting seat on one side. The first piston is pushed by air filling the air chamber, and a clamping plate is provided at the end of the first piston.

[0006] A further improvement is that the side of the clamping plate is a contoured surface, and the side of the clamping plate is adapted to the surface of the workpiece.

[0007] A further improvement is that the clamping inflation mechanism includes a second piston, which is slidably disposed in the air chamber of the mounting base on the other side. An inflation hole is provided in the second piston, and the inflation hole is connected to the air chamber.

[0008] A further improvement is that a sealing gasket is provided at the end of the second piston, and the sealing gasket is arranged around the inflation hole.

[0009] A further improvement is that the inflation hole is multi-segmented, with the diameter of each segment decreasing sequentially from the inside to the outside.

[0010] A further improvement is that an air inlet is provided on one side of the base, which is connected to the air circuit, and a switching valve is provided on the air circuit.

[0011] The beneficial effects of this utility model are as follows: By setting mounting seats on both sides of the base for mounting the clamping mechanism and the clamping inflation mechanism respectively, the inflation generates air pressure to drive the first and second pistons to extend synchronously to clamp the product, eliminating lateral forces on the product, making the product more stable during assembly, and improving the assembly qualification rate. By setting an inflation hole on the second piston, a synchronous sealing and air distribution function is achieved. Inflation completes the air distribution function while the second piston is clamping the product, effectively achieving the sealing requirements and significantly improving assembly efficiency. The sealing gasket enhances the sealing performance of the inflation, and the contact between the sealing gasket and the product reduces damage and lowers the product scrap rate. By setting the inflation structure on the second piston, accessories such as the air distribution bolts, air pipes, and gaskets, which previously required frequent disassembly and assembly, are integrated with the second piston, reducing the number of disassembly and assembly cycles. Consuming vulnerable parts into a fixed unit significantly reduces the wear and tear costs of the air distribution bolts, gaskets, and quick connectors, lowering the risk of damage and maintenance complexity.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0016] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

[0017] like Figure 1-3 As shown, this embodiment provides a product inflation self-clamping sealing device, including a base 1, with mounting seats 2 at both ends of the base 1. A clamping mechanism is provided in one mounting seat 2, and an inflation clamping mechanism is provided in the other mounting seat 2. An air passage 3 is provided in the base 1, and an inflation port is provided on one side of the base 1. The inflation port is connected to the air passage 3, and inflation is performed on the air passage 3 through the inflation port. A switching valve is provided on the air passage 3. An air chamber 4 is provided in both mounting seats 2 at both ends, and the air passage 3 and the air chamber 4 are connected. The gas supply from the air passage 3 to the air chamber 4 is switched by the switching valve to achieve rapid side switching. The product is clamped by inflating the product through the air passage 3 into the air chamber 4 and driving the clamping mechanism and the clamping inflation mechanism to move in opposite directions. The clamping inflation mechanism inflates the product while clamping it. By adopting a bidirectional air distribution clamping structure with the clamping mechanism and the clamping inflation mechanism, and applying Pascal's theorem, the bidirectional pressure is consistent, the product is not subjected to unidirectional pressure, the lateral force on the product is eliminated, and the product is ensured to reach a stable state during the assembly process.

[0018] The clamping mechanism includes a first piston 5, which is slidably disposed in the air chamber 4 of the mounting base 2 on one side. The first piston 5 is pushed by the air chamber 4 being filled with air. A clamping plate 6 is provided at the end of the first piston 5. By pushing the first piston 5, the clamping plate 6 is driven to clamp one side of the product. The side of the clamping plate 6 is a contoured surface, which is adapted to the surface of the workpiece, so that the clamping plate 6 can fit tightly against the surface of the product for clamping, thereby improving the stability of clamping.

[0019] The clamping and inflation mechanism includes a second piston 7, which is slidably disposed within the air chamber 4 of the mounting base 2 on the other side. Inflation within the air chamber 4 pushes the second piston 7, causing it to clamp the product on the other side. An inflation hole 8 is provided within the second piston 7, communicating with the air chamber 4. The inflation hole 8 is multi-segmented, with the diameter decreasing sequentially from the inside to the outside. When the second piston 7 clamps the product, the inflation hole 8 aligns with the product's aperture, allowing inflation to proceed. A sealing gasket 9 is provided at the end of the second piston 7, surrounding the inflation hole 8. The sealing gasket 9 improves the sealing between the second piston 7 and the product, ensuring effective inflation.

[0020] In use, the product is inflated through the inflation port, and the gas enters the air chamber 4 of the mounting base 2 on both sides through the air passage 3. The first piston 5 and the second piston 7 slide out from the mounting base 2 under the action of air pressure to clamp and fix the product placed on the base 1. The end of the second piston 7 is attached to the surface of the product, so that the inflation port 8 is aligned with the product hole. The gas in the air chamber 4 inflates the product through the inflation port 8 to complete the work.

[0021] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of this utility model is limited to these examples; within the framework of this utility model, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of this utility model as described above, which are not provided in the details for the sake of brevity. Any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
