In order to prevent the sliding and dislocation during the process, four push-pull rods 98 are hinged on the lower pressure frame 96, and the four push-pull rods 98 are respectively arranged corresponding to the positions of the four grooves 91. The push-pull rod 98 is a retractable rod. The push-pull rod 98 includes a fixed end three and a retractable end three. A spring four 99 is sleeved on the push-pull rod 98, and the two ends of the spring four 99 are respectively fixedly connected to the retractable end three and the fixed end three of the push-pull rod 98. Four clamping rods 910 are hinged on the connecting rod frame 93, and the four clamping rods 910 are respectively arranged corresponding to the positions of the four push-pull rods 98. The clamping rods 910 are hinged to adjacent push-pull rods 98, and each clamping rod 910 is slidably connected to two movable rods 912, and a resistance arc plate 913 is fixedly connected between the two movable rods 912 on the same clamping rod 910, and a spring five 911 is arranged between the movable rod 912 and the adjacent clamping rod 910.

[0045] The following is the entire working process and working principle of the above embodiment:

[0046] The staff places the car roof panel on the resistance frame 97 and then starts the telescopic motor 2. The telescopic shaft of the telescopic motor 2 drives the spring telescopic column 21 to move downward, and synchronously drives the rotating seat 31 to move downward. The rotating seat 31 drives the rotating block 32 to move downward. The rotating block 32 drives the resistance plate 35 to move downward through the spring telescopic rod 34 and makes the resistance plate 35 contact with the car roof panel. When the telescopic shaft of the telescopic motor 2 drives the spring telescopic column 21 to continue to move downward, it will compress the spring telescopic column 21 and the spring telescopic rod 34, and the resistance plate 35 will also push the car roof panel to move downward. At this time, the resistance plate 35 and the resistance frame 97 play a role in pressing and limiting the car roof panel. When the car roof panel moves downward, it will press the lower pressure frame 96, so that the lower pressure frame 96 drives the lower pressure rod 95 to move downward inside the fixed barrel 92. The downward movement of the lower pressure rod 95 will squeeze the spring three 94, and the lower pressure frame 96 will drive the four push-pull rods 98 to move downward synchronously and The push-pull rod 98 is adapted to extend and retract, and the push-pull rod 98 pushes the bottom end of the clamping rod 910 to swing outward with the hinge point with the connecting rod frame 93 as the axis, and the top end of the clamping rod 910 will swing inward, and the clamping rod 910 drives the contact arc plate 913 thereon to contact the automobile roof panel. At the same time, after the contact arc plate 913 has contacted the edge of the automobile roof panel, if the pressing rod 95 has not moved to the lowest position, the telescopic shaft of the telescopic motor 2 will still push the automobile roof panel to continue to descend. Because the contact arc plate 913 is set to be inclined, the automobile roof panel will be squeezed by the contact arc plate 913 when it descends, so that the contact arc plate 913 swings outward and the spring 5 911 and the push-pull rod 98 are adaptively deformed. The four contact arc plates 913 are used to assist in clamping the automobile roof panel, thereby improving the stability of the clamping limit of the automobile roof panel, and then clamping and fixing the automobile roof panel, preventing the automobile roof panel from being misaligned during the subsequent grinding process, and improving the grinding accuracy;

[0047] In addition, by arranging a push-pull rod 98, a spring four 99, a movable rod 912 and a spring five 911, when the automobile roof panel moves downward following the resistance plate 35, the four resistance arc plates 913 can all contact with the automobile roof panel, thereby avoiding the problem that the resistance arc plates 913 on two sides clamp the automobile roof panel but the resistance arc plates 913 on the other two sides do not clamp the automobile roof panel due to the inconsistent length and width of the automobile roof panel, thereby being able to adapt to automobile roofs with inconsistent lengths and widths.

[0048] Clip the towing assembly onto the edge of the vehicle roof panel and tow:

[0049] When the telescopic shaft of the telescopic motor 2 drives the spring telescopic column 21 and the rotating block 32 to move downward, the slide bar 36 will move downward synchronously, and the slide bar 36 will drive the swing cover 42 to move downward synchronously. At this time, the staff manually moves the swing cover 42 so that the notch 45 is aligned with the edge of the automobile roof panel, and in the process of the swing cover 42 continuing to move downward, the traction wheel 55 is in conflict with the inner and outer edges of the automobile roof panel. Under the conflicting effect of the inner and outer edges of the automobile roof panel, the two traction wheels 55 move to both sides, and the traction wheel 55 drives the two sliding frames 53 to slide on the support plate 51 to both sides through the double-headed motor 54. When the two sliding frames 53 slide to both sides, the spring 2 56 is stretched. At this time, the grinding wheel 69 also conflicts with the edge of the automobile roof panel. The elastic tension of the spring 2 56 enables the traction wheel 55 to tightly contact the automobile roof panel, thereby avoiding the problem of slipping due to loose contact during the rotation of the traction wheel 55.

[0050] At this time, the staff starts the double-headed motor 54. After the two double-headed motors 54 are started, they drive the two traction wheels 55 to rotate, and then they can pull the swinging assembly and the grinding assembly thereon to move synchronously. When the two traction wheels 55 encounter a thicker position of the automobile roof panel during traction, the traction wheels 55 are pushed by the automobile roof panel to cause the two traction wheels 55 to move to both sides. The traction wheels 55 will drive the double-headed motor 54 and the sliding frame 53 to move to both sides, and the two sliding frames 53 will further stretch the spring 2 56. With the pulling force of the spring 2 56, the traction wheels 55 can always be in close contact with the automobile roof panel, and then they can adapt to automobile roof panels of different thicknesses, thereby improving the effect of self-adaptation to the thickness of the automobile roof panel.

[0051] The grinding component grinds the burrs on the edge of the car roof panel:

[0052] When the double-headed motor 54 is started, when the output shaft at the top of one of the double-headed motors 54 rotates, the right-angle transmission rod 65 drives the transmission shaft 1 63 to rotate on the fixed plate 1 62 through the transmission hole 1 61, and the transmission shaft 1 63 rotates to drive the transmission shaft 2 67 to rotate on the fixed plate 2 66 through the belt 68, and the transmission shaft 2 67 drives the grinding wheel 69 to rotate, so that the grinding wheel 69 can grind the burrs on the edge of the automobile roof panel.

[0053] When the swing cover 42 is driven by the traction assembly to move, the swing cover 42 will move at the edge of the automobile roof panel, and the swing cover 42 will drive the slide bar 36 to move synchronously. At this time, the slide bar 36 will drive the rotating block 32 to rotate, and the rotating block 32 will drive the rotating seat 31 to rotate at the bottom of the spring telescopic column 21. When the traction wheel 55 drives the swing cover 42 to move along the edge of the automobile roof panel, the slide bar 36 can adaptively slide in the slide groove 33, thereby facilitating the grinding wheel 69 to adapt to the edges of automobile roof panels of different sizes for burr grinding.

[0054] Furthermore, since the shapes of the edges of the automobile roof panels are different, when the swing cover 42 moves from the vertical edge of the automobile roof panel to the warped edge or horizontal edge of the automobile roof panel, the two traction wheels 55 are in contact with the automobile roof panel due to the spring 2 56. The reaction force of the automobile roof panel on the two traction wheels 55 causes the swing cover 42 and the swing rod 43 to swing adaptively. The swing rod 43 drives the protruding rod 44 to slide in the arc groove of the swing groove frame 41. In addition, when the swing cover 42 is adaptively adjusted in angle, such as Figure 6 , Fig.11 As shown, when the swing cover 42 rotates to adapt to the edge of the automobile roof panel, the swing cover 42 will drive the slide bar 36 to move together, and the spring telescopic column 21 and the spring telescopic rod 34 will also be adaptively stretched and contracted, but the contact plate 35 is always in contact with the upper end of the roof panel, so that the traction wheel 55 and the grinding wheel 69 can better contact and pull and grind burrs on the edge of the automobile roof panel. By moving and adjusting the angle of the swing cover 42, the edges of automobile roof panels with different edge shapes can be ground, thereby improving the adaptability of the grinding wheel 69 to grinding automobile roof panels with different edge shapes.

[0055] When the swing cover 42 moves along the edge of the automobile roof panel to collide with the contact arc plate 913, because the contact arc plate 913 is in the shape of an arc, as the swing cover 42 continues to move, the swing slot frame 41 will push the contact arc plate 913, so that the contact arc plate 913 pushes the top of the clamping rod 910 and swings outward, and at the same time, the push-pull rod 98 contracts and compresses the spring 99, so that the swing cover 42 can smoothly pass through the clamping position of the contact arc plate 913 when moving along the edge of the automobile roof panel, and will not hinder the swing cover 42. The movement of the dynamic hood 42 will not hinder the grinding of burrs on the edge of the automobile roof panel by the grinding wheel 69. At the same time, the pushing of the swinging hood 42 will only push a single contact arc plate 913 and will not affect other contact arc plates 913. Other contact arc plates 913 will still contact and clamp the automobile roof panel. When the swinging hood 42 continues to move, the swinging hood 42 no longer contacts the contact arc plate 913. Under the elastic reset action of the spring four 99, the contact arc plate 913 continues to contact the edge of the automobile roof panel.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
