[0002] The product's air distribution sealing device is a device required for the assembly of automobile brake systems. The existing product's air distribution sealing device mainly uses air distribution bolts to screw and lock, which is cumbersome to operate. Tools need to be frequently used to disassemble and assemble the air head during loading and unloading and changing the model, which is inefficient. In addition, the air distribution bolts, washers and other structures need to be replaced regularly, and bolt locking can easily cause bumps and scratches on the product, affecting product quality; the connector uses a multi-petal threaded quick connector, which has a short lifespan and high maintenance cost, and the equipment is large in size and cannot be arranged in some small spaces; a single-sided thrust mechanism is used for clamping, but because the product lacks a limiting mechanism when using single-sided thrust clamping, it is subjected to force on one side during assembly, which is prone to deformation and causes product scrapping. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to propose a product inflation self-clamping sealing device and a method of use thereof, so as to solve the problems of high scrap rate due to product bumps and scratches, cumbersome operation and high maintenance cost.

[0004] Based on the above-mentioned purpose, the present invention provides a product inflation self-clamping sealing device, including a base, with mounting seats provided at both ends of the base, a clamping mechanism provided in the mounting seat on one side, and a clamping and inflation mechanism provided in the mounting seat on the other side, an air path provided in the base, and an air cavity provided in the mounting seat, the air path and the air cavity being connected, and the air path is used to inflate the air cavity to drive the clamping mechanism and the clamping and inflation mechanism to move toward each other to clamp the product, and the clamping and inflation mechanism is inflated when clamping the product.

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

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

[0007] A further improvement is that the inflation clamping mechanism includes a second piston, which is slidably arranged in the air cavity of the mounting seat on the other side, and an inflation hole is opened in the second piston, which is connected to the air cavity.

[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-stage, and the aperture of each stage of the inflation hole decreases successively from the inside to the outside.

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

[0011] The present invention also provides a method for using a product inflation self-clamping sealing device, comprising the following steps: S1: inflating through the inflation port, and the gas enters the air cavity of the mounting seats on both sides through the air path; S2: the first piston and the second piston slide out of the mounting seat under the action of air pressure, clamping and fixing the product placed on the base; S3: the end of the second piston is attached to the surface of the product, so that the inflation hole is aligned with the hole position of the product, and the gas in the air cavity is inflated into the product through the inflation hole to complete the work content.

[0012] The beneficial effects of the present invention are as follows: by arranging mounting seats on both sides of the base for installing the clamping mechanism and the clamping inflation mechanism respectively, air pressure is generated by inflation to drive the first piston and the second piston to extend synchronously to clamp the product, thereby eliminating the lateral force on the product, making the product more stable during assembly, and improving the qualified rate of assembly. By arranging an inflation hole on the second piston, a synchronous sealing and air distribution function is achieved, and the second piston is inflated to complete the air distribution function during the process of clamping the product, thereby effectively meeting the sealing requirements and effectively improving the assembly efficiency. The sealing performance of the inflation is improved by the sealing gasket, and the contact between the sealing gasket and the product reduces damage to the product and reduces the scrap rate of the product. By arranging the inflation structure on the second piston, accessories such as air distribution bolts, air pipes, and gaskets that originally needed to be frequently disassembled and assembled are integrated with the second piston, reducing the number of disassembly and assembly times, integrating the wearing parts into a fixed unit, greatly reducing the loss cost of air distribution bolts, gaskets, and quick connectors, and reducing the risk of damage and the complexity of maintenance.

[0018] like Figure 1-3 As shown, this embodiment provides a product inflation self-clamping sealing device, including a base 1, with mounting seats 2 provided at both ends of the base 1. A clamping mechanism is provided in one mounting seat 2, and a clamping and inflating mechanism is provided in the other mounting seat 2. An air path 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 path 3, and air is inflated into the air path 3 through the inflation port. A switching valve is provided on the air path 3, and an air cavity 4 is provided in each mounting seat 2 at both ends. The air path 3 and the air cavity 4 are connected. The switching valve switches the gas supply from the air path 3 to the air cavity 4, thereby achieving rapid side switching. Inflation of the air cavity 4 by the air path 3 drives the clamping mechanism and the clamping and inflating mechanism to move toward each other to clamp the product. The clamping and inflating mechanism is inflated while clamping the product.

[0019] The clamping mechanism includes a first piston 5, which is slidably arranged in the air cavity 4 of the mounting seat 2 on one side. The first piston 5 is pushed by inflating the air cavity 4. 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, and the side of the clamping plate 6 is adapted to the surface of the workpiece, so that the clamping plate 6 can fit tightly on the surface of the product for clamping, thereby improving the stability of the clamping.

[0020] The pneumatic clamping mechanism includes a second piston 7, which is slidably disposed within the air cavity 4 of the mounting seat 2 on the other side. The air in the air cavity 4 pushes the second piston 7, pushing the second piston 7 to clamp the other side of the product. A pneumatic hole 8 is provided in the second piston 7, which is connected to the air cavity 4. The pneumatic hole 8 is multi-stage, and the aperture of each section of the pneumatic hole 8 decreases from the inside to the outside. When the second piston 7 clamps the product, the pneumatic hole 8 corresponds to the hole position of the product, and the product is inflated through the pneumatic hole 8. A sealing gasket 9 is provided at the end of the second piston 7, which is disposed around the pneumatic hole 8. The sealing gasket 9 improves the sealing of the contact between the second piston 7 and the product, ensuring effective inflation.

[0021] This embodiment also provides a method for using a product inflation self-clamping sealing device, comprising the following steps: S1: inflating through the inflation port, and the gas enters the air cavity 4 of the mounting seats 2 on both sides through the air path 3; S2: the first piston 5 and the second piston 7 slide out of the mounting seat 2 under the action of air pressure, clamping and fixing the product placed on the base 1; S3: the end of the second piston 7 is attached to the surface of the product, so that the inflation hole 8 is aligned with the hole position of the product, and the gas in the air cavity 4 is inflated into the product through the inflation hole 8 to complete the work content.

[0022] By adopting a bidirectional air distribution clamping structure with the first and second pistons 5 and 7 and applying Pascal's law, bidirectional pressure is guaranteed to be consistent, eliminating unidirectional pressure on the product and eliminating lateral forces on the product. This ensures a stable state during assembly and eliminates lateral forces on the product. The synchronized sealing air distribution function allows air distribution to be completed during the clamping process, effectively achieving sealing requirements.
