Description

Technical Field

[0001] The present invention belongs to the technical field of automotive parts production equipment, and particularly relates to an equipment and a usage method for producing automotive exhaust pipes. Background Art

[0002] As a key component of a vehicle's exhaust system, the sealing performance of an automotive exhaust pipe directly affects engine efficiency, exhaust emissions, and noise control, and is an important indicator that must be strictly tested during the automotive manufacturing process. Traditional sealing detection of exhaust pipes mostly relies on manual operation. For example, by manually blocking the pipe orifice and injecting gas, and relying on experience to observe the change of the pressure gauge to judge whether there is leakage. Such methods are not only inefficient, but also easily affected by the technical level of the operators, resulting in poor consistency of detection results and a risk of misjudgment. In addition, manual blocking is difficult to ensure complete fitting with the pipe orifice. Especially when facing exhaust pipes of different specifications or shapes, air leakage problems caused by incomplete sealing frequently occur, seriously affecting the detection accuracy. Therefore, an equipment and a usage method for producing automotive exhaust pipes have been improved and designed. Summary of the Invention

[0003] In view of the above deficiencies existing in the prior art, the present invention provides an equipment and a usage method for producing automotive exhaust pipes to solve the problems in the above background art.

The second plug is driven by the third cylinder and is used for blocking the right end of the exhaust pipe; a detection device, installed on the frame, is used for detecting the sealing performance of the exhaust pipe; an air pump, connected to the left-side blocking mechanism and the right-side blocking mechanism, is used for providing air pressure.

[0006] Further, the slide rail of the left plugging mechanism is fixed to the mounting plate, and the slider slides along the slide rail and is connected to the second cylinder through the second mounting bracket.

[0007] Further, the rotating seat of the right plugging mechanism is hinged to the third support bracket, and the third cylinder drives the second plug to move along the axis of the third mounting bracket.

[0008] Further, the detection device includes a pressure sensor for real-time monitoring of the air pressure change inside the exhaust pipe.

[0009] Further, the air pump is communicated with the connection holes of the first plug and the second plug respectively through pipelines.

[0010] Further, the two-way clamp of the left plugging mechanism is connected to the positioning block through a spring for self-adaptive adjustment of the clamping force.

[0011] Further, a rubber sealing layer is provided on the surface of the second plug of the right plugging mechanism.

[0020] The U-shaped support block 203 of the clamping tooling 200 is fixed to the connection base 201 through the second support frame 204.

[0021] The slide rail 303 of the left-side plugging mechanism 300 is fixed to the mounting plate 302, and the slider 3031 slides along the slide rail 303 and is connected to the second cylinder 305 through the second mounting bracket 304.

[0022] The rotating seat 402 of the right-side plugging mechanism 400 is hinged to the third support frame 401, and the third cylinder 404 drives the second plug 405 to move along the axis direction of the third mounting bracket 403.

[0023] The detection device 500 includes a pressure sensor for real-time monitoring of the air pressure change inside the exhaust pipe 01.

[0024] The air pump 600 is respectively connected to the connection holes 3061 of the first plug 306 and the second plug 405 through pipelines.

[0025] The two-way clamp 307 of the left sealing mechanism 300 is connected to the positioning block 3041 through a spring for self-adaptively adjusting the clamping force.

[0026] The surface of the second plug 405 of the right sealing mechanism 400 is provided with a rubber sealing layer.

[0027] A method for using an equipment for manufacturing an automobile exhaust pipe includes the following steps: Place the exhaust pipe 01 on the U-shaped support block 203 of the clamping tooling 200, and drive the first cylinder 205 to make the clamping arms 207 clamp the exhaust pipe 01; Start the second cylinder 305 of the left sealing mechanism 300 to push the first plug 306 to seal the left end of the exhaust pipe 01; Start the third cylinder 404 of the right sealing mechanism 400 to push the second plug 405 to seal the right end of the exhaust pipe 01; Inflate the inside of the exhaust pipe 01 through the air pump 600, and use the detection device 500 to monitor the air pressure change to verify the sealing performance; After the detection is completed, release each sealing mechanism and the clamping tooling 200 in sequence, and take out the exhaust pipe 01.

[0028] Working principle: The equipment for manufacturing an automobile exhaust pipe of the present invention realizes efficient and accurate operation of exhaust pipe sealing detection through modular design and automatic control. Its working principle is as follows: Exhaust pipe fixing and clamping The operator horizontally places the exhaust pipe 01 to be detected on the U-shaped support block 203 of the clamping tooling 200. Start the first cylinder 205 to drive the symmetrically distributed clamping arms 207 to move towards the center, and firmly clamp the exhaust pipe through the inner anti-slip lines to ensure that there is no displacement or loosening during the detection process. The U-shaped support block 203 cooperates with the second support frame 204 to adapt to exhaust pipes of different diameters, improving the compatibility of the equipment.

[0029] Double-sided plugging and sealing Left-side plugging: Start the second cylinder 305 of the left sealing mechanism 300 to push the slider 3031 to slide along the slide rail 303, driving the second mounting bracket 304 and the first plug 306 to move towards the left end of the exhaust pipe. The two-way clamp 307 is connected to the positioning block 3041 through a spring, and adaptively adjusts the clamping angle and pressure when contacting the end of the exhaust pipe to ensure that the first plug 306 fits tightly with the pipe orifice.

[0030] Right-side plugging: The third cylinder 404 of the right-side plugging mechanism 400 drives the second plug 405 to move along the axis direction of the rotating seat 402. The rotating seat 402 is hinged to the third support frame 401, allowing the second plug 405 to automatically fine-tune its position according to the angle of the right end of the exhaust pipe; the rubber sealing layer on its surface further enhances the sealing performance of the plugging, preventing gas leakage.

[0031] Inflation and sealing detection The air pump 600 is respectively connected to the connection holes 3061 of the first plug 306 and the second plug 405 through pipelines, and fills the inside of the plugged exhaust pipe with gas at a set pressure. The high-precision pressure sensor built in the detection device 500 monitors the change of the internal air pressure of the exhaust pipe in real time. If the air pressure remains stable within the preset time, it is determined that the sealing performance is qualified; if the air pressure drops beyond the threshold value, it is determined that there is a leak.

[0032] Reset and exhaust pipe removal After the detection is completed, the air pump 600 stops supplying gas, and each cylinder resets in turn: the third cylinder 404 drives the second plug 405 to retract, the second cylinder 305 drives the first plug 306 to retreat, and the first cylinder 205 releases the clamping arm 207. The operator can safely remove the exhaust pipe to complete a single detection process.

[0033] Core advantages: Dynamic adaptability: Through structures such as slide rails-sliders, spring double clamps and rotating seats, the equipment can automatically compensate for the deviation of the shape or installation angle of the end of the exhaust pipe to ensure tight plugging.

[0034] Full-process automation: The cylinder drive and sensor feedback form a closed-loop control, reducing manual intervention and improving the detection efficiency and consistency.

[0035] Multi-specification compatibility: The modular clamping tooling and plugging mechanism support quick adjustment and are suitable for the detection requirements of exhaust pipes with different sizes and shapes.
