Description

Technical Field

[0001] The invention relates to the technical field of automobile welding processing, in particular to a welding device for processing automobile shock absorbers. Background Art

[0002] Automobile shock absorbers are an important part of the automobile suspension system. Their main function is to absorb and alleviate the impact and vibration from the road, thereby improving the comfort and handling performance of the car. The working principle of the shock absorber is to use the damping system including oil to consume the energy generated by the suspension spring, so that the vibration between the wheel and the road is gradually smoothed out, and the body is prevented from shaking violently up and down due to the rebound of the spring. The welding process of automobile shock absorbers is a key link in the manufacturing process, which involves connecting the different parts of the shock absorber (such as shock absorber cylinder, piston rod, end cover, etc.) together through welding technology. The quality of welding is directly related to the strength, durability and safety of the shock absorber.

Tooth grooves that mesh with the spur gears 504 on both sides are arranged on both sides of the rack 505, and a spring connected to the rack 505 is arranged inside the round seat 502. The upper clamping mechanism 5 is connected to the round seat 502 by rotating the upper clamping mechanism 5. 01 is flipped vertically to facilitate the assembly of the end cover parts, and the rack 505 is pushed inward. The spring limits the inward movement of the rack 505. The rack 505 drives the meshing spur gears 504 on both sides to rotate and rotate the fixed rotating bar seat 503 outward, and the clamping roller 506 connected to the rack 505 also deviates from the center of the round seat 502. At this time, the end cover can be conveniently placed in the center of the round seat 502, and then the rack 505 is loosened. The spring pulls the rack 505 back to its original position, thereby tightening the rotating bar seats 503 on both sides toward the center of the round seat 502, and the rack 505 pulls the clamping roller 506 close to the center of the round seat 502, so that a plurality of clamping rollers 506 clamp and fix the central end cover;

A semicircular strip seat 610 connected to the bracket 602 is arranged on the upper side of the two arc strips 606, and a rotating frame 612 is arranged at the center of the upper side of the semicircular strip seat 610. A clamping roller 3 614 is installed inside the rotating frame 612. The fixing of the central shock-absorbing cylinder is realized by a plurality of clamping rollers 609 and a clamping roller 3 614 on a movable rotating frame 612.

[0036] Furthermore, referring to Figure 7First, push the shock absorber cylinder into the device frame 1, and make the lower end of the shock absorber cylinder enter the inside of the end gear 605 and fall on the center of the second rotating seat 604, break open the arc strip 606 on one side, and the arc strip 606 drives the outer end of the clamping roller 2 609 to rotate outward, and through the transmission of the two meshing gears, the other arc strip 606 is connected to the outer rotation of the clamping roller 2 609, so as to facilitate the assembly of the shock absorber cylinder into the lower clamping mechanism 6. After the shock absorber cylinder is assembled, loosen the arc strip 606 on one side, and the two arc strips 606 rotate under the action of the torsion spring and clamp the middle shock absorber cylinder left and right. A rotating frame 612 is provided at the rear side. The rotating shaft 611 is movably connected to the semicircular bar seat 610, and a sliding shaft that slides inside and outside is arranged in the rotating shaft 611. The sliding shaft is sleeved with a squeezing spring 613 on the circumference of the sliding shaft, and the outer end of the sliding shaft is fixedly connected to the rotating frame 2 612. After the shock-absorbing cylinder is assembled, the semicircular bar seat 610 on the rotating bracket 602 is rotated, and the semicircular bar seat 610 rotates in the corresponding sliding grooves on the upper sides of the two arc-shaped bars 606, and cooperates with the left and right arc-shaped bars 606 to form an enclosure for the middle shock-absorbing cylinder, and the clamping roller 3 614 in the rotating frame 2 612 is subjected to the elastic force of the squeezing spring 613 on the circumference of the sliding shaft, and always keeps pushing the surface of one side of the shock-absorbing cylinder tightly;

[0037] Furthermore, spur gears 608 are fixed on the outer sides of the transfer points of the plurality of rotating racks 607, and the plurality of spur gears 608 are meshed with the lower end face gears 605, an inclined block 617 is arranged on the outer sides of the end face gears 605, and a torsion spring is arranged at the lower side transfer point of the end face gears 605, an insert block 616 is rotatably connected to the lower end of the vertical bar 615, and a stopper corresponding to the inclined block 617 is arranged on one side of the lower end of the insert block 616, a slot 618 corresponding to the lower end of the insert block 616 is arranged on the outer side of the bracket 602, an insert column 619 that slides inside and outside is arranged inside the slot 618, and the lower end of the insert block 616 A through hole corresponding to the plug column 619 is opened. After the semicircular bar seat 610 is turned open, the vertical bar 615 on the outer side of the semicircular bar seat 610 is lowered, and the plug block 616 at the lower end of the vertical bar 615 is turned open, so that the plug block 616 and the upper vertical bar 615 remain vertical, and the vertical bar 615 on the outer side of the lower bracket 602 is lowered. The vertical bar 615 drives the side gear of the rotating shaft 611, so that the rotating shaft 611 rotates exactly at an angle of 90 degrees, and the original vertical clamping roller 3 614 rotates straight, and the clamping roller 2 609 that is rotated flat is linked to the internal rotation, which is convenient for adjusting the shock-absorbing cylinder structure up and down, and is matched with the upper welding component;

[0038] Furthermore, after the plug block 616 connected to the vertical bar 615 slides down, the lower end of the plug block 616 contacts the inclined block 617 on the outside of the end gear 605, thereby causing the end gear 605 on the bracket 602 to deflect. At this time, the lower end of the plug block 616 is also inserted into the corresponding slot 618, pushing the plug post 619 inward, and allowing the plug post 619 to pass into the through hole at the lower end of the plug block 616, thereby locking the vertical bar 615 and the plug block 616. The squeezed and deflected end gear 605 drives the upper plurality of meshing spur gears 608 to rotate, and the plurality of spur gears 608 rotate exactly 90 degrees, thereby causing The clamping rollers 609 in the rotating racks 607 rotate vertically, a stud 7 is fixed to the outer side of the upper end of the welding rack 4, a through slot corresponding to the stud 7 is opened inside the vertical rail 3, a stud 2 8 is fixed to the outer side of the upper end of the slide 601, and a through slot corresponding to the stud 2 8 is opened at the lower part of the welding rack 4, and corresponding nuts are set on the studs 7 and 8.

[0039] Furthermore, referring to Figure 3 The lower end of the slide 601 is rotatably connected to a rotating rod 622, and the outer end of the rotating rod 622 is rotatably connected to a slider 621. The slider 621 slides back and forth on the lower side of the bracket 602, and a motor 603 connected to the rotating seat 2 604 is installed at the lower part of the bracket 602. The lower side of the bracket 602 is threadedly connected to a screw rod 620, and a rotating knob is fixed at the outer end of the screw rod 620.
