Description

Technical Field

[0001] The invention relates to the technical field of brake shoe welding, in particular to a welding device for a brake shoe of an automobile brake. Background Art

[0002] The brake shoe of an automobile brake is a key component in the automobile braking system, and is mainly welded from the brake shoe back plate and brake shoe pad. Traditional brake shoe welding processes are usually carried out manually or with semi-automated equipment, which has problems such as low production efficiency, unstable welding accuracy, and high labor intensity. Traditional welding equipment usually uses a single clamping and welding method, which makes it difficult to achieve automatic alternating feeding, precise positioning, and efficient welding of the brake shoe back plate and brake shoe pad, resulting in low production efficiency and difficulty in meeting the large-scale production needs of modern automobile parts. At present, although some automated welding equipment can achieve automatic welding of brake shoes, there are still problems such as complex structure, lack of coordination, and poor adaptability in the transportation, clamping, positioning, and welding of the brake shoe back plate and brake shoe pad.

The sliding drive shaft drives the left sliding rack and the left slide to slide along the upper slide through the upper gear. When the right slide moves toward the welding mechanism, the left slide moves away from the welding mechanism.

[0013] When the brake shoe is transported to the bottom of the left clamp by the upper conveyor belt, the lifting electric cylinder contracts to drive the lifting platform and the upper slide to descend, and the sliding transmission shaft slides relative to the upper gear, so that the left clamp reaches both sides of the brake shoe, and the left clamping electric cylinder extends to drive the left clamping block to descend, and the two left clamping claws are driven to clamp the brake shoe through the left clamping rod. Then the lifting electric cylinder extends to drive the upper slide to rise, and the brake shoe is lifted from the upper conveyor belt through the left clamping claw. The extension electric cylinder extends and retracts to drive the extension block to slide relative to the left slide to adjust the inner and outer positions of the brake shoe. Then the left slide slides along the upper slide to bring the brake shoe to the top of the welding mechanism. Then the upper slide descends, and the brake shoe is lowered between the two clamping discs, and the brake shoe falls onto the front support plate and the side support plate.

[0014] Then the left clamping jaw is released. At this time, the right clamping jaw is located above the brake shoe back plate on the upper conveyor belt. At this time, the right lifting motor drives the right lifting gear to rotate, and drives the lifting rod and the lifting frame to descend through the lifting rack, so that the right clamping jaw reaches both sides of the brake shoe back plate. The right clamping electric cylinder extends to drive the right clamping block to descend, and drives the two right clamping jaws to rotate inward through the right clamping rod, and clamps the brake shoe back plate through the right clamping jaw. Then the lifting frame rises, and the brake shoe back plate is picked up from the upper conveyor belt through the right clamping jaw.

[0019] When the brake shoe is placed between the two chucks, the compression spring is in a compressed state. When the brake shoe back plate and the brake shoe are placed, the bonding electric cylinder extends, and drives the bonding frame to rotate relative to the fixed plate through the connecting rod, and drives the lower rotating rod to rotate through the inner rotating rod and the sliding pin, thereby driving the lower push plate to rise. When the arc surface reaches above the outer push plate, the compression spring rebounds, driving the chuck to move inward along the rotating column, and the push plate drives the outer push plate to move inward along the outer guide column. At this time, the brake shoe is clamped by the two chucks, and the bonding frame rotates at the same time to bond the two bonding wheels to the brake shoe back plate. At this time, the two welding guns spot weld the brake shoe back plate and the brake shoe, and then the front support electric cylinder and the side support electric cylinder contract, so that the front support plate and the side support plate leave the bottom of the brake shoe.

[0020] Then the rotating motor drives the rotating column to rotate through the drive belt, the rotating column drives the chuck to rotate, the chuck drives the brake shoe back plate to rotate, and the brake shoe back plate and brake shoe are fully welded by the welding gun to form a brake shoe. After the welding is completed, the chuck drives the brake shoe back plate and brake shoe to rotate exactly 180 degrees. At this time, the brake shoe back plate is located at the bottom, and then the fitting electric cylinder shrinks, so that the chuck no longer clamps the brake shoe. At this time, the welded brake shoe falls onto the lower conveyor belt.

At this time, the welded brake shoe falls onto the lower conveyor belt 103.

[0053] The working principle of the automobile brake shoe welding device disclosed in the present invention is as follows: the upper conveying motor 108 drives the upper transmission roller 106 to rotate, the upper transmission roller 106 drives the upper conveyor belt 107 to move, and the upper conveyor belt 107 conveys the brake shoe back plate 4 and the brake shoe 5 inward, and the brake shoe 5 and the brake shoe back plate 4 are kept upright during the conveying process through the limit plate 105, and the feeding motor 112 drives the side transmission shaft 115 and the sliding transmission shaft 113 to rotate through the bottom transmission belt 117, and the side transmission shaft 115 drives the right sliding rack 202 and the right sliding frame 201 to slide along the frame body 101 through the conveying gear 116, and the sliding transmission shaft 113 drives the left sliding rack 214 and the left slide 213 to slide along the upper slide table 111 through the upper gear 114. When the right slide frame 201 moves toward the welding mechanism, the left slide 213 moves away from the welding mechanism, and when the left slide 213 moves toward the welding mechanism, the right slide frame 201 moves away from the welding mechanism. When the brake shoe 5 is transported to the bottom of the left clamping claw 222 by the upper conveyor belt 107, the lifting cylinder 109 contracts to drive the lifting platform 110 and the upper slide 111 to descend, and the sliding transmission shaft 113 slides relative to the upper gear 114, so that the left clamping claw 222 reaches both sides of the brake shoe 5, and the left clamping cylinder 219 extends to drive the left clamping block 220 to descend, and the left clamping rod 221 drives the two left clamping claws 222 to clamp the brake shoe 5. Then the lifting cylinder 109 extends to drive the upper slide 11 1 rises, and the brake shoe 5 is lifted from the upper conveyor belt 107 by the left clamping jaw 222. The extension cylinder 215 is extended and retracted to drive the extension block 216 to slide relative to the left slide 213, adjusting the inner and outer positions of the brake shoe 5. Then the left slide 213 slides along the upper slide 111, bringing the brake shoe 5 to the top of the welding mechanism. Then the upper slide 111 descends, and the brake shoe 5 is lowered between the two clamping plates 307, and the brake shoe 5 falls onto the front support plate 326 and the side support plate 328. Then the left clamping jaw 222 is released. At this time, the right clamping jaw 212 is located above the brake shoe back plate 4 on the upper conveyor belt 107. At this time, the right lifting motor 204 drives the right lifting gear 205 to rotate, and drives the lifting rod 206 and the lifting frame 208 to descend through the lifting rack 207, so that the right clamping jaw 212 reaches both sides of the brake shoe back plate 4. The right clamping electric cylinder 209 extends and drives the right clamping block 210 to descend. The two right clamping jaws 212 are driven to rotate inward through the right clamping rod 211, and the brake shoe back plate 4 is clamped by the right clamping jaw 212. Then the lifting frame 208 rises and picks up the brake shoe back plate 4 from the upper conveyor belt 107 through the right clamping jaw 212. Then the right sliding frame 201 slides along the frame body 101, and moves the brake shoe back plate 4 to the brake shoe 5 between the clamping discs 307 through the right clamping jaw 212. Then the right clamping jaw 212 is released.When the brake shoe 5 is placed between the two chucks 307, the compression spring 305 is in a compressed state. After the brake shoe back plate 4 and the brake shoe 5 are placed, the bonding electric cylinder 323 extends, and drives the bonding frame 320 to rotate relative to the fixed plate 310 through the connecting rod 319, and drives the lower rotating rod 317 to rotate through the inner rotating rod 315 and the sliding pin 316, thereby driving the lower push plate 311 to rise. When the arc surface 312 reaches above the outer push plate 308, the compression spring 305 rebounds, driving the chuck 30 7 moves inward along the rotating column 302, and the push plate 306 drives the outer push plate 308 to move inward along the outer guide column 309. At this time, the brake shoe 5 is clamped by the two chucks 307. At the same time, the laminating frame 320 rotates to laminate the two laminating wheels 322 on the brake shoe back plate 4. At this time, the two welding guns 324 spot weld the brake shoe back plate 4 and the brake shoe 5. Then the front support cylinder 325 and the side support cylinder 327 retract, so that the front support plate 326 and the side support plate 328 leave the bottom of the brake shoe 5. The rotating motor 301 then drives the rotating column 302 to rotate via the drive belt 303. The rotating column 302 drives the chuck 307 to rotate, which in turn drives the brake shoe back plate 4 to rotate. The welding gun 324 then fully welds the brake shoe back plate 4 and the brake shoe 5 to form the brake shoe. After welding is complete, the chuck 307 drives the brake shoe back plate 4 and the brake shoe 5 to rotate exactly 180 degrees. At this point, the brake shoe back plate 4 is located at the bottom. The fitting electric cylinder 323 then contracts, causing the chuck 307 to no longer clamp the brake shoe 5. The welded brake shoe now falls onto the lower conveyor belt 103. The lower conveyor motor 104 drives the lower drive roller 102 to rotate, driving the lower conveyor belt 103 to move. The welded brake shoe is placed on the lower conveyor belt 103, which then delivers the welded brake shoe.
