The heat insulation cover effectively blocks heat, avoids damage to electrical circuits and rubber and plastic parts caused by high temperature, reduces the risk of scalding and fire hazards, and at the same time maintains a comfortable temperature in the cockpit. In terms of material selection, aluminized steel plates are often used for automobile mufflers due to their good heat resistance and corrosion resistance; ceramic fibers have excellent heat insulation and sound insulation effects and can improve the combustion efficiency of the engine; fiberglass is a commonly used choice due to its high cost performance. These materials not only have excellent heat insulation performance but also have a noise reduction function, optimizing the driving experience.

[0022] According to the transverse length of the automobile exhaust pipe heat insulation cover workpiece, the first motor 5 drives the connecting screw 3 to rotate forward or reverse, and then drives the connecting screw 3 to rotate forward or reverse synchronously. In this way, the connecting screw 3 and the connecting screw 3 constitute a screw transmission structure, which drives the sliding sleeve 6 and the rotating cavity 7 set at the top of the sliding sleeve 6 and other components to move left and right to adapt to the transverse length of the automobile exhaust pipe heat insulation cover workpiece.

One end of the left fourth bevel gear 14 is fixedly connected to the output end of the second motor 15. The model of the second motor 15 is NEMA 230.

[0024] During the multi-point welding process of the automobile exhaust pipe heat insulation cover workpiece, the automobile exhaust pipe heat insulation cover workpiece can be quickly rotated, so that data collection is completed on different surfaces of the automobile exhaust pipe heat insulation cover workpiece and it corresponds to the welding device body 36, and then rapid processing can be carried out. When rotating the welding device body 36, by the forward or reverse rotation of the second motor 15, the two fourth bevel gears 14 rotate synchronously forward or reversely, and drive the engaged third bevel gear 13 to rotate. During the rotation of the third bevel gear 13, it drives the first bevel gear 10 to rotate in cooperation with the first transmission column 12, and drives the engaged first bevel gear 10 to rotate through the rotation of the first bevel gear 10. At the same time, the first bevel gear 10 drives the corresponding rotating block 8 to rotate in cooperation with the guide post 9 or the connecting column. Through the rotation of the rotating block 8, the rotation of the automobile exhaust pipe heat insulation cover workpiece is completed in cooperation with the clamping assembly. Using this method can effectively avoid rotating the automobile exhaust pipe heat insulation cover workpiece through a number of output devices, and further avoid the problem of damage to the automobile exhaust pipe heat insulation cover workpiece caused by the output difference of the output devices.

[0025] A clamping assembly is magnetically attracted to one end of each rotating block 8.

Vertical plates 23 are symmetrically and fixedly connected to one end of the connecting seat 20 far from the electromagnet 17, and resisting balloons 24 arranged in an inflation structure are fixedly connected to the outer walls of the opposite sides of the vertical plates 23.

[0026] When performing multi - point welding operations on the clamping of the automotive exhaust pipe heat shield, according to the size and shape of the automotive exhaust pipe heat shield, the installation position and orientation of the clamping assembly at one end of the rotating block 8 can be flexibly adjusted. After determining the specific position and orientation, the control panel 19 is used to control the battery 18 to magnetically attract the electromagnetic block 17 to one end of the rotating block 8. Then, the clamping of the automotive exhaust pipe heat shield workpiece can be quickly completed by the left and right clamping assemblies. This method has no limitations, is easy to operate, and is convenient for dealing with the processing of various automotive exhaust pipe heat shields.

[0027] Silicone anti - slip pads 25 are fixedly connected to the outer side walls corresponding to the abutting balloons 24. A number of through - holes are arrayed on the outer side walls corresponding to the silicone anti - slip pads 25. Hemispherical silicone bumps 26 are fixedly connected to the interiors of the through - holes. Exhaust valves are provided at the bottoms of the abutting balloons 24, and the bottoms of the abutting balloons 24 are fixedly connected to one ends of the transmission pipes 28.

The air pump assemblies 27 are fixedly connected to the outer side walls of the vertical plates 23, and the model of the air pump assemblies 27 is 30L - 1100W.

[0028] By the operation of the air pump assembly 27, gas is transmitted into the interiors of the abutting balloons 24 through the transmission pipes 28, and then inflation operations are performed on the abutting balloons 24, so that the abutting balloons 24 fit according to the shape and size required for the clamping of the automotive exhaust pipe heat shield. The silicone anti - slip pads 25 and the inflated abutting balloons 24 generate pressure to make the silicone bumps 26 abut against the clamping area of the automotive exhaust pipe heat shield, further improving the clamping effect. After processing, exhaust operations are performed by pressing the exhaust valves, so that the welded automotive exhaust pipe heat shield can be quickly taken out.

[0029] The top end of the operation base 1 is fixedly connected with a top plate 29 arranged in an "L" shape. The top end of the top plate 29 is fixedly connected with an electromagnetic slide rail 30. A number of electromagnetic sliders 32 are slidably connected inside the electromagnetic slide rail 30. The top ends of the electromagnetic sliders 32 are fixedly connected to the inner top ends of the connecting frames 33.

The output end of the cylinder 35 penetrates through the top end of the installation piece 34 and is fixedly connected to the top end of the welding device body 36. Position sensors 37 are fixedly connected to the top ends of the rear installation pieces 34.

[0030] During the multi-point welding process, the magnitude of the current passing through the coil of the electromagnetic slide rail 30 is changed, thereby changing the magnitude of the electromagnetic force received by the electromagnetic slider 32. By precisely controlling the current change, different electromagnetic sliders 32 receive different magnitudes of electromagnetic force, so as to move different distances. At the same time, through the set position sensor 37, the position parameter data of the electromagnetic slider 32 is obtained in real time, and then compared with the required position parameter data for movement. At the same time, when performing multi-point welding, the cylinder 35 outputs corresponding distance parameter data, thereby driving the welding device body 36 to move vertically, making the welding end of the welding device body 36 correspond to the welding part, and then completing the welding operation. By adopting this method, the welding operation of the automobile exhaust pipe heat shield can be completed quickly, improving the efficiency.

[0031] The specific usage process of this embodiment is as follows: First, according to the transverse length of the automobile exhaust pipe heat shield workpiece, the lead screw drive structure formed by the connecting lead screw 3 and the connecting lead screw 3 drives components such as the sliding sleeve 6 and the rotating cavity 7 provided at the top of the sliding sleeve 6 to move left and right to adapt to the transverse length of the automobile exhaust pipe heat shield workpiece; Secondly, according to the size and shape of the automobile exhaust pipe heat shield, the installation position and orientation of the clamping assembly at one end of the rotating block 8 are flexibly adjusted. After determining the specific position and orientation, the control panel 19 controls the storage battery 18 to magnetically attract the electromagnetic block 17 to one end of the rotating block 8; Then, the air pump assembly 27 works, and the gas is transmitted to the inside of the contact balloon 24 through the transmission pipe 28, and then the contact balloon 24 is inflated, so that the contact balloon 24 fits according to the shape and size required for clamping the automobile exhaust pipe heat shield; After that, the magnitude of the current passing through the coil of the electromagnetic slide rail 30 is controlled, thereby changing the magnitude of the electromagnetic force received by the electromagnetic slider 32. By precisely controlling the current change, different electromagnetic sliders 32 receive different magnitudes of electromagnetic force, so as to move different distances. At the same time, through the set position sensor 37, the position parameter data of the electromagnetic slider 32 is obtained in real time, and then compared with the required position parameter data for movement. At the same time, when performing multi-point welding, the cylinder 35 outputs corresponding distance parameter data, thereby driving the welding device body 36 to move vertically, making the welding end of the welding device body 36 correspond to the welding part, and then completing the welding operation; Finally, the rotation of the rotating block 8 is combined with the clamping assembly to complete the rotation of the automobile exhaust pipe heat shield workpiece, so that different surfaces of the automobile exhaust pipe heat shield workpiece are completed with data collection and correspond to the welding device body 36, and then rapid processing is carried out.
