[0026] Embodiment

[0027] Reference Figures 1-5 For the embodiment of the utility model, the embodiment provides a welding trolley that can adapt to a track, which can realize that when different spacing slide rails 102 are encountered, the spacing of the slide rails 102 does not need to be adjusted again, and the spacing of the sliding block 103 is adjusted to flexibly adapt to the slide rails 102 with different spacing.

[0028] The welding mechanism 100 comprises a welding table 101, slide rails 102 fixedly connected to the outer surfaces of the two sides of the welding table 101 respectively, sliding blocks 103 slidingly sleeved on the outer surfaces of the slide rails 102, and a welding gun 104 arranged above the welding table 101;

[0029] It should be explained that the slide rail 102 is used to limit the slide block 103, so that the slide block 103 can move in the opposite direction of the welding table 101. The welding gun 104 is used to convey the welding wire from the welding wire reel to the welding seam, and the welding wire enters the molten pool through the conducting nozzle to form the welding seam.

[0030] The distance adjusting mechanism 200 comprises a frame 201 arranged above the slide rail 102, a connecting column 202 fixedly installed on the inner wall of the frame 201 through a bearing, a special-shaped groove 203 respectively arranged on the outer surfaces of the two sides of the connecting column 202, a protruding block 204 slidingly connected in the special-shaped groove 203, a positioning block 205 fixedly connected on the top of the two sides of the protruding block 204, a positioning rod 206 fixedly connected on the inner walls of the two sides of the frame 201 and matched with the positioning block 205, a rotating rod 207 fixedly connected on the penetrating end of the frame 201, and a hand wheel 208 fixedly installed on the other end of the rotating rod 207.

[0031] It should be explained that the positioning block 205 is limited by the positioning rod 206, so that the positioning block 205 limits the slide block 103, and then the slide block 103 limits the protruding block 204, so that the protruding block 204 can drive the slide block 103 to move linearly through the rotation of the special-shaped groove 203.

[0032] In addition, a locking mechanism 300 is arranged on the outer surface of the frame 201 and matched with the rotating rod 207.

[0033] It should be further explained that the locking mechanism 300 is used to limit the rotating rod 207, so as to avoid the rotation of the rotating rod 207 due to vibration during the welding process, which causes the slide block 103 to be stuck on the surface of the slide rail 102.

[0034] Specifically, the bottom of the protruding block 204 is fixedly connected with the top of the slide block 103, and the bottom of the welding gun 104 is fixedly connected with the top of the frame 201.

[0035] Further, the inner surface of the positioning block 205 is in sliding contact with the outer surface of the positioning rod 206, and the outer surface of the rotating rod 207 is in rotating contact with the inner surface of the frame 201.

[0036] Preferably, the locking mechanism 300 comprises a fixed block 301 fixedly connected on the outer surface of the frame 201, a sliding rod 302 slidingly connected on the inner surface of the fixed block 301, and a spring 303 sleeved on the outer surface of the sliding rod 302.

[0037] It should be explained that the locking mechanism 300 further comprises a connecting rod 304 fixedly connected on the end of the sliding rod 302 away from the fixed block 301, a first friction plate 305 fixedly installed on the other end of the connecting rod 304, and a second friction plate 306 fixedly connected on the outer surface of the rotating rod 207 and matched with the first friction plate 305.

[0038] The first friction plate 305 and the second friction plate 306 are both made of aluminum oxide material with high hardness, high wear resistance, good corrosion resistance and high temperature resistance, and the first friction plate 305 and the second friction plate 306 can generate strong friction force when in contact.

[0039] Further, one end of the spring 303 is fixedly connected to the outer surface of the fixed block 301, and the other end of the spring 303 is fixedly connected to the outer end surface of the connecting rod 304.

[0040] Specifically, the locking mechanism 300 further comprises a supporting sleeve 307 fixedly connected to the outer surface of the vehicle frame 201 and cooperating with the connecting rod 304, and the outer surface of the connecting rod 304 is in sliding contact with the inner surface of the supporting sleeve 307.

[0041] In use, when encountering slide rails 102 with different distances, the sliding rod 302 is pulled to drive the connecting rod 304 and the first friction plate 305 to move synchronously, so that the first friction plate 305 moves to a position away from the second friction plate 306 to contact the limiting of the rotating rod 207;

[0042] The hand wheel 208 is rotated to drive the rotating rod 207 and the connecting column 202 to rotate, the connecting column 202 drives the two special-shaped grooves 203 to rotate synchronously, the positioning rod 206 limits the positioning block 205, the positioning block 205 limits the sliding block 103, and the sliding block 103 limits the protruding block 204, so that the two protruding blocks 204 drive the sliding block 103 to move linearly towards each other through the rotation of the two special-shaped grooves 203, and the two sliding blocks 103 move to positions with equal distance from the slide rails 102;

[0043] The sliding rod 302 is loosened, the connecting rod 304 is reset by the reaction force of the spring 303, the connecting rod 304 drives the first friction plate 305 to move to a position in contact with the second friction plate 306 to limit the rotating rod 207, so as to avoid the distance between the sliding blocks 103 changing during welding, thereby avoiding the sliding blocks 103 being stuck on the surface of the slide rails 102.

[0044] In summary, through the cooperation of the components in the distance adjusting mechanism 200 and the locking mechanism 300, the sliding blocks 103 can be adjusted to the same distance as the slide rails 102, and the position of the sliding blocks 103 can be prevented from deviating during welding, thereby avoiding the sliding blocks 103 being stuck on the surface of the slide rails 102, and improving the universality and adaptability of the welding trolley while ensuring that the sliding blocks 103 always maintain the correct relative position with the slide rails 102.
