Description

Technical Field

[0001] This utility model relates to the field of automotive muffler flange processing technology, and in particular to an automotive muffler flange processing positioning mechanism. Background Technology

[0002] The automotive muffler flange is a key mechanical interface in the automotive exhaust system that connects the muffler to other components (such as the exhaust pipe and catalytic converter). Its design directly affects the sealing, durability, and noise reduction performance of the exhaust system. Conventional clamping and positioning devices for muffler flanges of different shapes are time-consuming and labor-intensive, making it inconvenient to clamp and position muffler flanges of different shapes.

[0003] Prior art CN210937921U discloses a four-hole flange positioning device for an automotive muffler, including a support plate, a first cylinder, a piston rod, a limiting rod, a second cylinder, grippers, a base, a T-slot, a first nut, a base plate, a second nut, a bottom plate, an arc-shaped groove, a third nut, and a vertical plate. The flange plate at the end of the automotive muffler to be welded is placed against the support plate. Then, the piston rod of the first cylinder is controlled to retract, causing the limiting rod to engage with the flange hole of the muffler flange plate. Next, the second cylinder controls the grippers to clamp and fix the muffler flange plate. The clamping and positioning of the four-hole flange plate of the muffler is achieved between the gripper and the support plate. Since a T-shaped groove is provided on the base, after removing the first bolt and the first nut from the base and the base plate, the position of the base plate on the base can be adjusted. After loosening the second nut, the base plate can be rotated around the common central axis of the two arc grooves. After loosening the third nut, the angle between the support plate and the vertical plate can be adjusted, so that the position, orientation and angle of the support plate can be adjusted according to the position of the muffler flange plate, thereby facilitating the clamping and positioning of flange plates of mufflers of different shapes.

[0004] In normal use, the existing technology for adjusting the angle between the support plate and the vertical plate is time-consuming and laborious, making it inconvenient to adjust the angle between the support plate and the vertical plate, which in turn makes it inconvenient to adjust the position angle of the muffler flange plate.
