[0023] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0024] A precision filter welding device includes a machine platform 1 for placing a filter housing, wherein the filter housing includes an upper housing 2 with a top sealed and a lower housing 3 with both ends open:

[0025] The top of the machine 1 is provided with a positioning mechanism 4 for fixing the filter housing, wherein a rotating mechanism 5 is provided above the machine 1 outside the filter housing, the rotating mechanism 5 is connected to the machine 1 through an adjusting mechanism 6, and a welding mechanism 7 is also provided on the rotating mechanism 5, wherein grinding mechanisms 8 are provided on both sides of the welding mechanism 7; Figure 1 , 2 As shown, the connection between the upper shell 2 and the lower shell 3 is positioned by the positioning mechanism 4 to prevent the connection between the two from being misaligned, wherein the height of the rotating mechanism 5 and the welding mechanism 7 and other components can be adjusted by the adjusting mechanism 6, and the rotating mechanism 5 can adjust the position of the welding mechanism 7, so that the welding mechanism 7 reciprocates 180 degrees clockwise and counterclockwise on the outside of the filter housing, so that the two sets of welding mechanisms 7 can fully perform 360-degree welding without dead ends on the connection between the upper shell 2 and the lower shell 3, and the grinding mechanisms 8 located on both sides of the welding mechanism 7 can grind and polish the connection between the upper shell 2 and the lower shell 3. After the connection between the two is polished, it is convenient for the subsequent welding mechanism 7 covering the position to weld it, and the grinding mechanism 8 downstream after welding can grind and polish the welding joint to remove the protruding welding points or welding slag at the welding joint, so as to facilitate subsequent painting and other work.

[0026] The positioning mechanism 4 includes a limit seat 41 located in the opening at the connection between the upper shell 2 and the lower shell 3, wherein a mounting seat 43 is fixed to the top of the limit seat 41 through a convex seat 42, and a screw hole 44 extending to the outside of the bottom of the limit seat 41 is provided in the mounting seat 43, wherein a screw rod 45 driven by a motor 146 is screwed in the screw hole 44, and a vertical rod 47 is provided on the machine 1 outside the screw rod 45, wherein the limit seat 41, the convex seat 42 and the mounting seat 43 are provided with a fixed channel 48 for accommodating the vertical rod 47, and a flexible support seat 10 is provided on the top of the mounting seat 43 to abut against the inner top wall of the upper shell 2, wherein a groove 11 is provided on the top surface of the support seat 10, and the groove 11 is connected to the vacuum pump through a hose 12;

[0027] like Figure 2As shown, when the upper shell 2 and the lower shell 3 are sleeved on the limit seat 41 during processing, the limit seat 41 can play a positioning role on the connection between the upper shell 2 and the lower shell 3 to prevent the two from horizontally moving and causing misalignment, wherein the motor I46 drives the screw 45 to rotate in the screw hole 44 to drive the limit seat 41, the convex seat 42 and the mounting seat 43 to move slowly upward, thereby driving the support seat 10 to abut against the inner top wall of the upper shell 2 and make the two close together. In this process, the slowly moving convex seat 42 and the fixed channel 48 on the limit seat 41 move upward on the vertical rod 47, and the vertical rod 47 abuts against the fixed channel 48 to prevent the mounting seat 43 and other components from rotating together with the screw 45. When the support seat 10 abuts against the inner top wall of the upper shell 2, the vacuum pump further locks the upper shell 2 by evacuating the groove 11 through the hose 12, preventing the upper shell 2 from sliding off the positioning mechanism 4 or preventing the upper shell 2 from separating from the lower shell 3. After the processing is completed, the motor I46 drives the limit seat 41 to move down to the top of the machine table 1 through the screw 45, and at the same time drives the boss 42 and the mounting seat 43 to move down, so that people can remove the lower shell 3 and the upper shell 2.

[0028] The rotating mechanism 5 includes an annular seat 51, wherein a circle of slide grooves 52 are arranged around the inner side wall of the annular seat 51, and a circular ring 53 is also arranged inside the annular seat 51, wherein the circular ring 53 is provided with a screw 54 with one end embedded in the slide groove 52, and an outer gear ring I55 is also arranged at the bottom of the circular ring 53, wherein the outer gear ring I55 is provided with a gear I56 meshing with it, and the gear I56 is driven by a motor II57, and a mounting frame for fixing the motor II57 is arranged on the annular seat 51;

[0029] When the position of the welding mechanism 7 needs to be adjusted, the motor II57 drives the gear I56 to rotate to drive the outer gear ring I55 to rotate 180 degrees clockwise or counterclockwise. At this time, the outer gear ring I55 drives the ring 53 to rotate in the annular seat 51, which will drive the welding mechanism 7 to rotate at the same time, so as to adjust the position of the welding mechanism 7, so that the two groups of welding mechanisms 7 can cover the entire outer wall of the connection between the upper shell 2 and the lower shell 3 to perform welding work. In the above process, when the ring 53 rotates in the annular seat 51, it will drive the screw 54 to slide in the slide groove 52, and the ring 53 is prevented from slipping out of the annular seat 51 by the slide groove 52 against the screw 54.

[0030] The welding mechanism 7 includes a welding gun 71 which is obliquely arranged on the top of the circular ring 53 and rotatably connected thereto, and mounting ears 9 are arranged on the top of the circular ring 53 and located on both sides of the welding gun 71, wherein rotating shafts penetrating the corresponding mounting ears 9 are arranged on the two side walls of the welding gun 71, and the bottom end of the welding gun 71 extends into the opening of the circular ring 53 and is directly opposite to the connection between the upper shell 2 and the lower shell 3, and a push plate 72 is arranged on the top of the welding gun 71, and an electric push rod 73 movably connected thereto is obliquely arranged on the bottom of the push plate 72, and an extension plate 74 for fixing the electric push rod 73 is arranged on the outer wall of the circular ring 53.

[0031] When the positioning mechanism 4 fixes the upper shell 2 and the lower shell 3, the output shaft of the electric push rod 73 contracts, so that it drives the welding gun 71 to rotate with the rotating shaft as the center through the push plate 72, so that the bottom end of the welding gun 71 is tilted and abuts against the outer wall of the connection between the upper shell 2 and the lower shell 3, so as to weld the connection between the two. At this time, the rotating mechanism 5 drives the welding mechanism 7 to rotate, so that the welding mechanism 7 can cover the entire outer wall of the connection between the upper shell 2 and the lower shell 3, and then perform 360-degree welding without dead ends. After the welding is completed, the output shaft of the electric push rod 73 extends out, and drives the welding gun 71 to rotate with the rotating shaft as the center through the push plate 72, so that the bottom end of the welding gun 71 is separated from the connection between the upper shell 2 and the lower shell 3. At this time, the removal of the upper shell 2 and the lower shell 3 can be facilitated, and it is also convenient to reinsert the new upper shell 2 and the lower shell 3.

[0032] The adjusting mechanism 6 includes a plurality of screw rods I61 arranged at the outer bottom of the annular seat 51, wherein a screw rod II62 corresponding to the screw rod I61 is arranged on the machine 1, and the screw rod I61 is connected to the corresponding screw rod II62 via a screw tube 63, and an outer gear ring II64 is arranged on the screw tube 63, wherein an inner gear ring 65 which is jacketed on the plurality of outer gear rings II64 and meshed with the outer gear rings II64 is arranged above the machine 1, and annular limiting plates 66 are respectively arranged on the screw tubes 63 located on the upper and lower sides of the inner gear ring 65, and a plurality of gear teeth 67 are axially arranged on the outer side wall of the inner gear ring 65, wherein a gear II68 which meshes with the gear teeth 67 is also arranged on the outer side of the inner gear ring 65, and the gear II68 is driven by a motor III69.

[0033] When it is necessary to adjust the height of the rotating mechanism 5 and the welding mechanism 7 through the adjusting mechanism 6, the motor III69 drives the inner gear ring 65 to rotate through the gear II68 and the gear 67, and the inner gear ring 65 rotates by driving multiple groups of outer gear rings II64. When the outer gear ring II64 rotates, it will drive the screw 63 to rotate on the screw I61 and the screw II62, thereby expanding or reducing the distance between the screw I61 and the screw II62 inside the screw 63, thereby indirectly adjusting the height of the rotating mechanism 5 and the welding mechanism 7 above them. In the above process, multiple groups of screws 63 can be adjusted at the same time by the motor III69, so as to improve efficiency while reducing costs.

[0034] The grinding mechanism 8 includes brackets 81 arranged on both sides of the bottom of the welding gun 71, wherein each group of brackets 81 is provided with a grinding roller 82 located in the opening of the ring 53, and the bottom end of the welding gun 71 is located between the two groups of grinding rollers 82. The grinding roller 82 is driven by a motor IV83 arranged on the brackets 81, and one end of the grinding roller 82 is tightly attached to the outer wall of the connection between the upper shell 2 and the lower shell 3.

[0035] like Figure 2 , 4 As shown, when the rotating mechanism 5 drives the welding mechanism 7 to rotate clockwise and counterclockwise on the outside of the upper shell 2 and the lower shell 3, the welding gun 71 in the welding mechanism 7 drives the grinding roller 82 and the motor IV83 to move in the same direction and speed in the ring 53 through the bracket 81. At this time, the motor IV83 drives the grinding roller 82 to grind the connection between the upper shell 2 and the lower shell 3 at both ends of the welding gun 71. The grinding mechanism 8 at the upstream of the welding gun 71 can grind the outer wall of the connection between the upper shell 2 and the lower shell 3 to facilitate the welding work of the welding gun 71, and the grinding mechanism 8 at the downstream can polish and grind the weld at the connection between the upper shell 2 and the lower shell 3 to remove the welding slag and protrusions in the weld to facilitate subsequent painting and other work.

[0036] In this embodiment, the limiting seat 41, the protruding seat 42 and the mounting seat 43 are integrally arranged, wherein the diameter of the mounting seat 43 is smaller than the diameter of the limiting seat 41, and the diameter of the limiting seat 41 is adapted to the size of the internal opening at the connection between the upper shell 2 and the lower shell 3.

[0037] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
