[0002] The exhaust pipe is part of the car's exhaust system, playing multiple important functions in the overall operation of the vehicle. Exhaust pipes are typically made of metal, primarily stainless steel and ordinary steel. Stainless steel exhaust pipes offer good corrosion resistance, can withstand high temperatures and exhaust gas corrosion, and have a long service life. During the manufacturing and processing of automotive exhaust pipes, the edges must be ground and deburred.
[0003] Existing technologies do not have a structure that can simultaneously grind the inner and outer sides of both ends of the exhaust pipe. As a result, during the production and processing of existing automobile exhaust pipes, the burrs at the edge of the exhaust pipe are mostly removed manually with a trimming knife or by using equipment to remove the burrs from the inner and outer edges of the left or right ends one by one.

[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. This is a deburring device for automobile exhaust pipe production. The device involves placing the batch of steel pipes on a bottom clamping block, replacing the grinding head with one corresponding size, and slowly controlling the second telescopic electric cylinder on one side to bring the grinding head into contact with one end of the steel pipe. Then, by holding the adjusting threaded rod and rotating it forward or backward, the grinding head is moved up or down until the grinding groove of the grinding head coincides with the opening of the exhaust pipe. The same steps are then repeated to adjust the position of the grinding head at the other end and reset both ends. At this point, a normal workpiece can be placed on the bottom clamping block. The control panel controls the two second telescopic electric cylinders at the bottom of the operating table to retract simultaneously. The retracting second telescopic electric cylinders pull the two sets of grinding heads at both ends inward simultaneously through the connecting plate and connecting arm until both sets of grinding heads are simultaneously clamped at both ends of the exhaust pipe and centered. This device facilitates the centering and deburring position adjustment for different batches of steel pipes.
[0016] 2. This is a deburring device for automobile exhaust pipe production. By using a control panel to control the extension of the first telescopic electric cylinder to push the top clamping block and use the bottom clamping block to clamp and fix the exhaust pipe, the support leg continues to control the rotary motor to drive the grinding head to rotate through the shaft to grind the deburring at both ends of the exhaust pipe. Finally, the second telescopic electric cylinder extends and the first telescopic electric cylinder pulls the top clamping block to retract, so that the grinding head is withdrawn from both ends of the exhaust pipe and the top clamping block moves upward to release the clamping and fixing of the exhaust pipe. This process can be repeated to quickly grind the double ends of multiple sets of exhaust pipes in the same batch. Attached Figure Description

[0029] By setting up a connecting arm 301, a sliding hole 302, and a limiting rod 303, the grinding mechanism 4 is supported and its movement direction is limited. By setting up an adjusting threaded rod 404, a rotary motor 405, and a rotating shaft 406, the connecting arm 301 and the grinding mechanism 4 are pulled to move and perform burr treatment on the exhaust pipe.
[0030] Working principle: When a deburring device for automobile exhaust pipe production is used, in the initial state, the control panel 101 is first set on the front of the operating table 1. The support arm 2 fixedly connected to the upper surface of the operating table 1 is provided with a first telescopic electric cylinder 201 and a top clamping block 202, and a bottom clamping block 203 is provided below the top clamping block 202 to facilitate clamping and fixing the exhaust pipe. The connecting arm 301 and the connecting plate 304 are slidably connected in the movable grooves 103 opened on both sides of the operating table 1. The bottom of the connecting plate 304 is connected to the fixed plate 305 and the second telescopic electric cylinder 306. At the same time, a grinding mechanism 4 is also provided on the connecting arm 301 to facilitate the simultaneous movement of the left and right grinding mechanisms 4 to perform double-end grinding deburring treatment on the exhaust pipe.
[0031] When double-end burr treatment is required on the exhaust pipe, first place the batch of steel pipes on the bottom clamping block 203, replace the grinding head 407 with one of the corresponding sizes, and slowly control the second telescopic electric cylinder 306 on one side to drive the grinding head 407 to contact one end of the steel pipe. Then, hold the adjusting threaded rod 404 and rotate it forward or backward to control the grinding head 407 to move up or down, so that the grinding groove of the grinding head 407 coincides with the rim of the exhaust pipe. Then, follow the same steps to adjust the position of the grinding head 407 on the other end and reset the grinding heads 407 on both ends. At this time, the normal workpiece can be placed on the bottom clamping block 203. Use the control panel 101 to control the two second telescopic electric cylinders 306 at the bottom of the operating table 1 to retract simultaneously. The retracting second telescopic electric cylinders 306 are connected by the connecting plate 304 and the connecting arm 3. 01. The two sets of grinding heads 407 at both ends of the traction are moved inward simultaneously until the two sets of grinding heads 407 are simultaneously locked at both ends of the exhaust pipe and centered. Then, the control panel 101 controls the first telescopic electric cylinder 201 to extend and push the top clamping block 202 to clamp and fix the exhaust pipe with the bottom clamping block 203. At this time, the support leg 102 continues to control the rotary motor 405 to drive the grinding head 407 to rotate through the rotating shaft 406 to perform burr treatment and grinding at both ends of the exhaust pipe. Finally, the second telescopic electric cylinder 306 extends and the first telescopic electric cylinder 201 pulls the top clamping block 202 to retract, so that the grinding head 407 is withdrawn from both ends of the exhaust pipe and the top clamping block 202 moves upward to release the clamping and fixing of the exhaust pipe. This process can be repeated to quickly grind multiple sets of exhaust pipes in this batch at both ends.
