Detailed implementation manners

[0026] The following further elaborates on the detailed implementation manners of the technical solution with reference to the accompanying drawings.

[0027] As Figure 1 shown, the tool repair mechanism needs to repair the seam welding wheel of the welding wheel mechanism. The welding wheel mechanism 312 at least includes a welding wheel base 3153, a seam welding drive 3154 provided on the welding wheel base 3153, a seam welding rod rotatably provided on the welding wheel base 3153, and a seam welding wheel 3152 provided at one end of the seam welding rod. The output end of the seam welding drive 3154 is provided with a pinion gear 3155, and a large gear 3156 meshing with the pinion gear 3155 is provided at the other end of the seam welding rod. The seam welding drive 3154 can drive the seam welding wheel 3152 to rotate through gear cooperation for seam welding. The structural configuration of the second seam welding unit is the same as that of the first seam welding unit, and its working principle is prior art, so no further elaboration is made here.

[0028] As Figures 1-3 shown, the tool repair mechanism includes: a tool repair base 331, which is provided on the welding wheel movable rod 3151 of the welding wheel mechanism and is provided with a tool repair movable groove 3311; a tool repair unit 332, which is movably provided in the tool repair movable groove 3311 and at least has a tool repair blade 3322 for repairing the seam welding wheel 3152 and a tool repair auxiliary wheel 3323 for abutting against the seam welding wheel 3152; and a tool repair elastic member 333, which is provided between the tool repair unit 332 and the tool repair base 331 for abutting the tool repair blade 3322 and the tool repair auxiliary wheel 3323 of the tool repair unit 332 against the seam welding wheel 3152.

[0029] Specifically, waste chips will be generated during welding and adhere to the seam welding wheel 3152. The tool repair mechanism is used to repair the outer surface of the seam welding wheel 3152 during its operation to keep it flat at all times for convenient welding. The tool repair auxiliary wheel 3323 abuts against the seam welding wheel 3152 movably. When it abuts against the seam welding wheel 3152, the tool repair blade 3322 abuts against the seam welding wheel 3152 with the tool repair auxiliary wheel 3323 as a reference and extends into the seam welding wheel 3152 by a certain distance, so that it can repair the surface of the seam welding wheel 3152, thereby ensuring the beauty of the weld seam and the product yield.

[0030] Furthermore, the knife repair base 331 is sleeved and fixed on the welding wheel movable rod 3151 through the connecting member 335. The number of the connecting members 335 is set to be several. They are all annular and adapted to the cylindrical welding wheel movable rod 3151. The end side of the connecting member 335 has a screw hole, and the screw passes through the knife repair base 331 and cooperates with the screw hole to realize the fixation of the knife repair base 331.

[0031] As Figure 2 shown, the knife repair unit 332 further has a knife repair slider 3321 movably arranged in the knife repair movable groove 3311. A knife repair groove 336 for installing the knife repair blade 3322 is provided on the knife repair slider 3321. The knife repair groove 336 has a screw hole, and the knife repair blade 3322 is detachably installed in the knife repair groove 336 through the cooperation of the fastener and the screw hole. When the fastener is screwed in and placed in the screw hole, the knife repair blade 3322 can be fixed. After the fastener is withdrawn from the screw hole, the knife repair blade 3322 can be loosened.

[0032] Furthermore, the knife repair blade 3322 has a number of adjustment holes 337. The position of the fastener placed in the adjustment hole 337 can be adjusted to change the length of the knife repair blade 3322 extending out of the knife repair slider 3321. In order to adjust the length of the knife repair blade 3322 extending out of the knife repair slider 3321, an adjustment bolt 334 is provided at the bottom of the knife repair blade 3322. The adjustment bolt 334 is threadedly connected to the knife repair slider 3321, and the telescoping of the knife repair blade 3322 can be realized through the adjustment bolt 334.

[0033] Furthermore, the knife repair elastic member 333 can push the knife repair unit 332 to move so that it always abuts against the resistance welding wheel 3152. Compared with the original method of driving and extending the knife repair blade 3322 numerically controlled, the structure of the knife repair elastic member 333 is simpler. It can realize full-automatic fitting with the resistance welding wheel 3152, avoid damage to the resistance welding wheel 3152 due to mechanical failures, and has a lower cost at the same time. The knife repair elastic member 333 is preferably a spring. The number of the knife repair elastic members 333 is set to be two, and they respectively abut against the left and right ends of the bottom of the knife repair slider 3321, so that it will not swing when pushing the knife repair slider 3321 to move.

[0034] Furthermore, at least one slider fixing block 338 for limiting the knife repair slider 3321 is provided on the knife repair base 331. The slider fixing block 338 is arranged at the open end of the knife repair movable groove 3311. After the slider fixing block 338 closes the open end of the knife repair movable groove 3311, the knife repair slider 3321 can be limited in the knife repair movable groove 3311.

[0035] Furthermore, in order to facilitate the adjustment of the length of the trimming blade 3322 extending out, the number of slider fixing blocks 338 is increased to two. The two slider fixing blocks 338 are respectively placed on the left and right sides of the trimming slider 3321. The trimming blade 3322 is located between the two slider fixing blocks 338. At the same time, steps 339 are formed by recessing on the left and right sides of the trimming slider 3321, and the two slider fixing blocks 338 are movably clamped on the steps 339 to realize the limit of the trimming slider 3321.
