Description

Technical Field

[0001] This invention relates to the field of brake welding technology, and in particular to a fully automatic welding device for processing automobile brakes. Background Technology

[0002] In the manufacturing process of automotive brakes, the welding of the inner and outer rings of the brake pads is one of the key technological steps. Traditional welding methods typically involve manual feeding, positioning, and welding, which is not only inefficient but also prone to inconsistent weld quality due to human error, affecting the overall performance of the brake. Furthermore, traditional welding equipment often lacks automation integration, making continuous production difficult and hindering improvements in production efficiency and product consistency. While some existing automated welding devices can achieve partial automation, they still have shortcomings in areas such as clamping and positioning the inner and outer rings of the brake pads, automatic feeding, and welding precision control. For example, some devices use fixed clamping mechanisms, which are difficult to adapt to workpieces of different sizes, or uneven clamping forces can cause workpiece displacement during welding, affecting weld quality. In addition, traditional feeding mechanisms are often complex in structure, have high maintenance costs, and are prone to jamming or inaccurate feeding during continuous operation. Therefore, there is an urgent need to develop a fully automated welding device capable of precise feeding, reliable clamping, and efficient welding of the inner and outer rings of the brake pads to improve production efficiency, ensure welding quality, and meet the needs of modern automotive parts manufacturing. Summary of the Invention

[0003] To address the aforementioned technical problems, the present invention adopts the following technical solution: a fully automatic welding device for processing automotive brakes, comprising a welding mechanism for welding the inner ring and outer ring of brake pads, the welding mechanism comprising a base, and a front feeding mechanism for feeding the inner ring of brake pads and a rear feeding mechanism for feeding the outer ring of brake pads.

[0004] Furthermore, the welding mechanism includes a turntable rotatably mounted on a base, an internal gear ring fixedly mounted on the turntable, a rotating motor fixedly mounted on the base, a motor gear fixedly mounted on the motor shaft of the rotating motor, the motor gear meshing with the internal gear ring, an inner fixing ring fixedly mounted on the turntable, and four positioning blocks fixedly mounted on the turntable.

[0005] Furthermore, a discharge ramp is fixedly installed on the base, a discharge electric cylinder is fixedly installed on the discharge ramp, and a push rod is fixedly installed on the output end of the discharge electric cylinder.

[0006] Furthermore, a welding plate is fixedly installed on the base, a welding electric cylinder is fixedly installed on the welding plate, a limit block is fixedly installed on the welding plate, a welding frame is slidably installed on the limit block, multiple welding guns are fixedly installed on the welding frame, and the welding frame is fixedly installed with the output end of the welding electric cylinder.

[0007] Furthermore, the inner fixing ring is provided with four clamping modules. Each clamping module includes a fixing block and a crossbar fixedly installed on the inner fixing ring. A slide rod is slidably installed inside the fixing block. A movable rod is fixedly installed on the slide rod. A compression spring is provided between the movable rod and the fixing block. Two inner rotating rods are rotatably installed on the movable rod. A clamping rod is rotatably installed on the inner rotating rod. The clamping rod is rotatably installed with the crossbar. The slide rod is slidably installed with the inner fixing ring.

[0008] Furthermore, three arc-shaped blocks are fixedly installed on the base.

[0009] The rotating motor drives the motor gears to rotate, which in turn drives the internal gear ring, turntable, and inner fixed ring to rotate. The turntable and inner fixed ring rotate a quarter turn each time. When the sliding rod moves to the arc block, the arc block causes the sliding rod and movable rod to slide along the fixed block. The compression spring is stretched, causing the inner rotating rod to rotate, which in turn causes the clamping rod to rotate relative to the crossbar, causing the clamping rod to open. The brake pad inner ring is placed on the positioning block by the front loading mechanism. Then the turntable and inner fixed ring rotate a quarter turn. When the sliding rod leaves the arc block, the compression spring rebounds, causing the sliding rod and movable rod to slide back to their original position along the fixed block. The inner rotating rod drives the two clamping rods to clamp the brake pad inner ring on the positioning block. Then the turntable carries the brake pad inner ring to the rear loading mechanism. At this time, the arc block next to the rear loading mechanism causes the clamping rod to open, allowing the brake pad outer ring to be placed smoothly next to the brake pad inner ring. When the rear loading mechanism places the brake pad outer ring onto the brake pad... After the inner ring is moved to the side, the turntable and inner fixed ring rotate another quarter turn, the sliding rod disengages from the arc block, and the clamping rod clamps the inner and outer rings of the brake pad. Then the turntable carries the inner and outer rings of the brake pad to the welding plate. The welding cylinder extends, causing the welding frame to slide along the limit block, allowing multiple welding torches to reach the inner and outer rings of the brake pad. Multiple welding holes are opened on the outer ring of the brake pad. The welding torches weld the inner and outer rings of the brake pad through the welding holes. At this time, the clamping rod maintains its clamping of the inner and outer rings of the brake pad. Then the turntable continues to rotate another quarter turn. When the sliding rod reaches the arc block next to the discharge slope, the arc block pushes the sliding rod and the movable rod, causing the clamping rod to open. At this time, the clamping rod no longer clamps the inner and outer rings of the brake pad. The discharge cylinder retracts, and the pushed rod pushes the welded inner and outer rings of the brake pad onto the discharge slope and away from the device.

[0010] Furthermore, the front feeding mechanism includes an inner ring frame fixedly installed on the base, a ring-releasing frame fixedly installed on the inner ring frame, a brake pad inner ring stacked inside the ring-releasing frame, an ejector plate slidably installed on the inner ring frame, a ring-releasing electric cylinder fixedly installed on the inner ring frame, the output end of the ring-releasing electric cylinder being fixedly installed with the ejector plate, and an arc-shaped groove at the end of the ejector plate conforming to the arc surface of the brake pad inner ring.

[0011] When the positioning block moves to the front of the ejector plate, the release cylinder retracts, causing the ejector plate to slide along the inner ring frame. The ejector plate pushes the inner ring of the lowest brake pad inside the release frame through the arc groove at the end. A discharge chute is provided below the release frame. The discharge chute allows only the lowest brake pad inner ring to be ejected at a time. The brake pad inner ring is pushed onto the positioning block by the ejector plate, and the inner ring of the brake pad inner ring fits against the positioning block.

[0012] Furthermore, the rear feeding mechanism includes an outer ring frame fixedly mounted on the base, an outer ring electric cylinder fixedly mounted on the outer ring frame, an outer ring push rod slidably mounted on the outer ring frame, the outer ring push rod being fixedly mounted to the output end of the outer ring electric cylinder, a downward pressing electric cylinder fixedly mounted on the outer ring frame, a downward pushing block slidably mounted inside the outer ring frame, the downward pushing block being fixedly mounted to the output end of the downward pressing electric cylinder, and a downward pushing arc groove provided on the outer ring frame, the downward pushing arc groove being located below the downward pushing block.

[0013] When the positioning block moves the inner ring of the brake pad to the side of the outer ring bracket, the positioning block is located below the downward push arc groove. The outer ring electric cylinder retracts, pushing the outer ring of the brake pad along the outer ring bracket through the outer ring push rod, raising the outer ring of the foremost brake pad above the downward push arc groove. At this time, because the outer ring electric cylinder provides a horizontal force to the outer ring of the brake pad, the outer ring of the brake pad will not fall directly out along the downward push arc groove. The downward pressing electric cylinder extends, driving the downward pushing block to descend. The downward pushing block presses down the outer ring of the brake pad on the downward push arc groove, so that the outer ring of the brake pad falls through the downward push arc groove to the side of the inner ring of the brake pad, and fits against the inner ring of the brake pad on the positioning block, completing the feeding of the outer ring of the brake pad.

[0014] The beneficial effects of this invention compared with the prior art are: (1) This invention adopts a fully automatic feeding, clamping, welding and unloading mechanism, and realizes continuous welding operation of the inner and outer rings of brake pads through turntable indexing conveyor, which significantly reduces manual intervention, improves production efficiency, and is suitable for mass production needs; (2) This invention uses the combination of arc block and spring driven clamping module to realize automatic clamping and loosening of the inner and outer rings of brake pads, ensuring accurate positioning of workpieces during welding, avoiding displacement or loosening, thereby improving welding accuracy and product consistency; (3) This invention can automatically complete the accurate alignment and welding of the inner and outer rings of brake pads, reduce manual operation errors, reduce dependence on skilled workers, is suitable for welding needs of brakes of different specifications, and effectively reduce production costs.

Detailed Implementation

[0024] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0025] Example: Reference Figures 1-8 A fully automatic welding device for processing automotive brakes includes a welding mechanism for welding the inner ring 4 and the outer ring 5 of the brake pads. The welding mechanism includes a base 101 and is provided with a front feeding mechanism for feeding the inner ring 4 of the brake pads and a rear feeding mechanism for feeding the outer ring 5 of the brake pads.

[0026] like Figures 2-4As shown, the welding mechanism includes a turntable 102 rotatably mounted on a base 101, an internal gear ring 103 fixedly mounted on the turntable 102, a rotating motor 104 fixedly mounted on the base 101, a motor gear 105 fixedly mounted on the motor shaft of the rotating motor 104, the motor gear 105 meshing with the internal gear ring 103, an inner fixing ring 114 fixedly mounted on the turntable 102, and four positioning blocks 123 fixedly mounted on the turntable 102.

[0027] like Figures 2-4 As shown, a discharge slope 106 is fixedly installed on the base 101, a discharge electric cylinder 107 is fixedly installed on the discharge slope 106, and a push rod 108 is fixedly installed on the output end of the discharge electric cylinder 107.

[0028] like Figures 2-4 As shown, a welding plate 109 is fixedly installed on the base 101, a welding electric cylinder 110 is fixedly installed on the welding plate 109, a limit block 111 is fixedly installed on the welding plate 109, a welding frame 112 is slidably installed on the limit block 111, and multiple welding guns 113 are fixedly installed on the welding frame 112. The welding frame 112 is fixedly installed with the output end of the welding electric cylinder 110.

[0029] like Figures 2-4 As shown, four clamping modules are provided on the inner fixing ring 114. Each clamping module includes a fixing block 120 and a crossbar 116 fixedly installed on the inner fixing ring 114. A slide rod 122 is slidably installed inside the fixing block 120. A movable rod 119 is fixedly installed on the slide rod 122. A compression spring 121 is provided between the movable rod 119 and the fixing block 120. Two inner rotating rods 118 are rotatably installed on the movable rod 119. A clamping rod 117 is rotatably installed on the inner rotating rod 118. The clamping rod 117 is rotatably installed with the crossbar 116. The slide rod 122 is slidably installed with the inner fixing ring 114.

[0030] like Figures 2-4 As shown, three curved blocks 115 are fixedly installed on the base 101.

[0031] The rotation of motor 104 drives motor gear 105 to rotate, which in turn drives internal gear ring 103, turntable 102, and inner fixed ring 114 to rotate. Turntable 102 and inner fixed ring 114 rotate a quarter turn each time. When slide rod 122 moves to arc block 115, arc block 115 will drive slide rod 122 and movable rod 119 to slide along fixed block 120. Compression spring 121 is stretched, causing inner rotating rod 118 to rotate, which in turn drives clamping rod 117 to rotate relative to cross bar 116, causing clamping rod 117 to open. The brake pad inner ring 4 is then placed on positioning block 123 by the front loading mechanism. Then, the turntable 102 and the inner fixed ring 114 rotate a quarter turn. When the slide rod 122 leaves the arc surface block 115, the compression spring 121 rebounds, causing the slide rod 122 and the movable rod 119 to slide back along the fixed block 120. The inner rotating rod 118 drives the two clamping rods 117 to clamp the brake pad inner ring 4 on the positioning block 123. Then, the turntable 102 carries the brake pad inner ring 4 to the rear loading mechanism. At this time, the arc surface block 115 next to the rear loading mechanism causes the clamping rods 117 to open, allowing the brake pad outer ring 5 to be smoothly placed next to the brake pad inner ring 4. When the rear loading mechanism places the brake pad outer ring 5... After being placed next to the inner ring 4 of the brake pad, the turntable 102 and the inner fixing ring 114 rotate another quarter turn, causing the slide rod 122 to disengage from the arc block 115, allowing the clamping rod 117 to clamp the inner ring 4 and the outer ring 5 of the brake pad. Then, the turntable 102, carrying the inner ring 4 and the outer ring 5 of the brake pad, reaches the welding plate 109. The welding cylinder 110 extends, causing the welding frame 112 to slide along the limiting block 111, allowing multiple welding torches 113 to reach the inner ring 4 and the outer ring 5 of the brake pad. Multiple welding holes are provided on the outer ring 5 of the brake pad, and the welding torches 113 pass through the welding holes on the inner ring 4 and the outer ring 5 of the brake pad. The inner ring 4 and outer ring 5 of the brake pad are welded together. At this time, the clamping rod 117 holds the inner ring 4 and outer ring 5 of the brake pad. Then the turntable 102 continues to rotate a quarter turn. When the slide rod 122 reaches the arc block 115 next to the discharge slope 106, the arc block 115 pushes the slide rod 122 and the movable rod 119, causing the clamping rod 117 to open. At this time, the clamping rod 117 no longer holds the inner ring 4 and outer ring 5 of the brake pad. The discharge cylinder 107 retracts and pushes the welded inner ring 4 and outer ring 5 of the brake pad onto the discharge slope 106 through the push rod 108, leaving the device.

[0032] like Figure 5 , Figure 6As shown, the front feeding mechanism includes an inner ring frame 201 fixedly installed on the base 101, a ring-releasing frame 202 fixedly installed on the inner ring frame 201, a brake pad inner ring 4 stacked inside the ring-releasing frame 202, an ejector plate 204 slidably installed on the inner ring frame 201, a ring-releasing electric cylinder 203 fixedly installed on the inner ring frame 201, the output end of the ring-releasing electric cylinder 203 is fixedly installed with the ejector plate 204, and the end of the ejector plate 204 is provided with an arc-shaped groove that fits with the arc surface of the brake pad inner ring 4.

[0033] When the positioning block 123 moves to the front of the ejector plate 204, the release cylinder 203 retracts, causing the ejector plate 204 to slide along the inner ring frame 201. The ejector plate 204 pushes the lowest brake pad inner ring 4 in the release frame 202 through the end arc groove. A discharge groove is provided below the release frame 202. The discharge groove allows only the lowest brake pad inner ring 4 to be ejected at a time. The brake pad inner ring 4 is pushed onto the positioning block 123 by the ejector plate 204, and the inner ring of the brake pad inner ring 4 fits against the positioning block 123.

[0034] like Figure 7 , Figure 8 As shown, the rear feeding mechanism includes an outer ring frame 301 fixedly installed on the base 101, an outer ring electric cylinder 302 fixedly installed on the outer ring frame 301, an outer ring push rod 303 slidably installed on the outer ring frame 301, the outer ring push rod 303 is fixedly installed with the output end of the outer ring electric cylinder 302, a downward pressing electric cylinder 304 is fixedly installed on the outer ring frame 301, a downward pushing block 305 is slidably installed inside the outer ring frame 301, the downward pushing block 305 is fixedly installed with the output end of the downward pressing electric cylinder 304, and a downward pushing arc groove 306 is provided on the outer ring frame 301, the downward pushing arc groove 306 is located below the downward pushing block 305.

[0035] When the positioning block 123 moves the inner ring 4 of the brake pad to the side of the outer ring frame 301, the positioning block 123 is located below the downward push arc groove 306. The outer ring electric cylinder 302 retracts, and pushes the outer ring 5 of the brake pad along the outer ring frame 301 through the outer ring push rod 303, raising the foremost outer ring 5 of the brake pad above the downward push arc groove 306. At this time, because the outer ring electric cylinder 302 provides a horizontal force on the outer ring 5 of the brake pad, the outer ring 5 of the brake pad will not fall directly along the downward push arc groove 306. The downward pressing electric cylinder 304 extends, driving the downward pushing block 305 to descend. The downward pushing block 305 presses down the outer ring 5 of the brake pad on the downward push arc groove 306, so that the outer ring 5 of the brake pad falls next to the inner ring 4 of the brake pad through the downward push arc groove 306 and fits with the inner ring 4 of the brake pad on the positioning block 123, completing the feeding of the outer ring 5 of the brake pad.

[0036] The working principle of the fully automatic welding device for automobile brake processing disclosed in this invention is as follows: The rotating motor 104 drives the motor gear 105 to rotate, thereby driving the internal gear ring 103, the turntable 102, and the inner fixed ring 114 to rotate. The turntable 102 and the inner fixed ring 114 rotate a quarter turn each time. When the slide rod 122 moves to the arc block 115, the arc block 115 will drive the slide rod 122 and the movable rod 119 to slide along the fixed block 120. The compression spring 121 is stretched, causing the inner rotating rod 118 to rotate, thereby driving the clamping rod 117 to rotate relative to the cross bar 116, causing the clamping rod 117 to open. When the positioning block 123 moves to the front of the ejector plate 204, the ring-releasing electric cylinder 203 retracts, driving the ejector plate 204 to move along the inner fixed ring 114. The ring frame 201 slides, and the push plate 204 pushes the inner ring 4 of the lowest brake pad inside the ring holder 202 through the arc-shaped groove at the end. A discharge groove is provided below the ring holder 202. The discharge groove allows only the lowest brake pad inner ring 4 to be pushed out at a time. The brake pad inner ring 4 is pushed out by the push plate 204 onto the positioning block 123. The inner ring of the brake pad inner ring 4 is in contact with the positioning block 123. Then the turntable 102 and the inner fixed ring 114 rotate a quarter turn. When the slide rod 122 leaves the arc block 115, the compression spring 121 rebounds, causing the slide rod 122 and the movable rod 119 to slide back along the fixed block 120. The inner rotating rod 118 drives the two clamping rods 117 to clamp the brake pad inner ring 4 on the positioning block 123. Then the turntable 102 drives the two clamping rods 117 to clamp the brake pad inner ring 4 on the positioning block 123. As the inner ring 4 of the brake pad moves to the rear loading mechanism, the arc block 115 next to the rear loading mechanism causes the clamping rod 117 to open, allowing the outer ring 5 of the brake pad to be smoothly placed next to the inner ring 4. When the positioning block 123 moves the inner ring 4 to the outer ring bracket 301, the positioning block 123 is located below the downward pushing arc groove 306. The outer ring electric cylinder 302 retracts, pushing the outer ring 5 of the brake pad along the outer ring bracket 301 through the outer ring push rod 303, raising the foremost outer ring 5 of the brake pad above the downward pushing arc groove 306. At this time, because the outer ring electric cylinder 302 provides a horizontal force to the outer ring 5 of the brake pad, the outer ring 5 of the brake pad will not fall directly along the downward pushing arc groove 306. The downward pressing electric cylinder 304 extends, driving the downward pushing block 305 to descend, pushing down... Block 305 presses down the outer ring 5 of the brake pad on the downward pushing arc groove 306, causing the outer ring 5 of the brake pad to fall next to the inner ring 4 of the brake pad through the downward pushing arc groove 306 and fit against the inner ring 4 of the brake pad on the positioning block 123, completing the feeding of the outer ring 5 of the brake pad. The turntable 102 and the inner fixing ring 114 rotate another quarter turn, and the sliding rod 122 disengages from the arc surface block 115, so that the clamping rod 117 clamps the inner ring 4 and the outer ring 5 of the brake pad. Then, the turntable 102 carries the inner ring 4 and the outer ring 5 of the brake pad to the welding plate 109. The welding electric cylinder 110 extends and drives the welding frame 112 to slide along the limiting block 111, so that multiple welding guns 113 reach next to the inner ring 4 and the outer ring 5 of the brake pad. Multiple welding holes are opened on the outer ring 5 of the brake pad.The welding torch 113 welds the inner and outer rings of the brake pads 4 and 5 through the welding holes. During this process, the clamping rod 117 holds the inner and outer rings of the brake pads 4 and 5. Then, the turntable 102 continues to rotate a quarter turn. When the sliding rod 122 reaches the arc-shaped block 115 next to the discharge slope 106, the arc-shaped block 115 pushes the sliding rod 122 and the movable rod 119, causing the clamping rod 117 to open. At this point, the clamping rod 117 no longer holds the inner and outer rings of the brake pads 4 and 5. The discharge cylinder 107 retracts, and the ejector rod 108 pushes the welded inner and outer rings of the brake pads 4 and 5 onto the discharge slope 106, removing them from the device.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the present invention based on the technical solution and inventive concept of the present invention should be covered within the scope of protection of the present invention.
