Description

Technical Field

[0001] This utility model relates to the field of welding auxiliary equipment technology, specifically to a welding auxiliary tooling for brake brackets. Background Technology

[0002] Brake brackets provide mounting positions and support for other brake components, such as brake pads, brake calipers, and pistons, ensuring that each component maintains the correct relative position during braking and enabling the braking function to be realized normally.

[0003] The welding locations of brake brackets are typically related to their structural design and component composition, and the welding positions vary depending on the type of bracket (e.g., disc, drum). However, generally speaking, there are many locations requiring straight-line welding. Currently, straight-line welding usually involves workers directly holding a welding torch to perform the weld, which not only demands high skill from the welder but also easily causes arm fatigue from prolonged torch handling. Therefore, an auxiliary tooling for brake bracket welding is proposed. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a welding auxiliary fixture for a brake bracket, comprising a fixed base, a guide rail fixedly mounted on the upper end of the fixed base, a slider slidably connected to the outer wall of the guide rail, a first linear drive mechanism acting on the slider provided on the guide rail, a cylinder fixedly mounted on the upper end of the slider, a fixed rod fixedly connected to the end of the telescopic rod of the cylinder, a second linear drive mechanism provided between one end of the fixed rod and the movable rod, and a clamping mechanism provided at the other end of the movable rod.

[0006] As a further preferred embodiment of this technical solution, the clamping mechanism consists of a first clamping plate, a second clamping plate, and locking screws. The first clamping plate is fixedly connected to the end of the movable rod, and the second clamping plate is located to the side of the first clamping plate. The second clamping plate and the first clamping plate are fixedly connected by two locking screws.

[0007] As a further preferred embodiment of this technical solution, the first clamping plate and the second clamping plate are respectively provided with matching grooves at their respective ends that are close to each other.

[0008] As a further preferred embodiment of this technical solution, the adapter groove is adapted to the outer shell of the welding torch.

[0009] As a further preferred embodiment of this technical solution, the first linear drive mechanism consists of a first threaded rod, a fixed vertical plate, and a first motor. Fixed vertical plates are fixedly installed on both sides of the upper end of the guide rail. A first threaded rod is rotatably installed between the two fixed vertical plates. A first motor is fixedly installed at the end of one of the fixed vertical plates away from the first threaded rod. The output shaft of the first motor is fixedly connected to the first threaded rod. The slider is threaded onto the outer surface of the first threaded rod.

[0010] As a further preferred embodiment of this technical solution, the second linear drive mechanism comprises a second motor, a movable block, and a second threaded rod. The movable block is fixedly connected to the end of the movable rod away from the first clamping plate. The movable block is slidably installed in a groove formed in the fixed rod. The second threaded rod is provided in the groove, and one end of the second threaded rod is rotatably connected to the inner wall of the groove. The movable block and the movable rod are threaded onto the other end of the second threaded rod.

[0020] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, a welding auxiliary fixture for a brake bracket includes a fixed base 1. A guide rail 2 is fixedly installed on the upper end of the fixed base 1. A slider 3 is slidably connected to the outer wall of the guide rail 2. A first linear drive mechanism acting on the slider 3 is provided on the guide rail 2. A cylinder 7 is fixedly installed on the upper end of the slider 3. A fixed rod 8 is fixedly connected to the end of the telescopic rod of the cylinder 7. A second linear drive mechanism is provided between one end of the fixed rod 8 and the movable rod 10. The other end of the movable rod 10 is provided with a clamping mechanism.

[0021] The clamping mechanism consists of a first clamping plate 11, a second clamping plate 12, and locking screws 16. The first clamping plate 11 is fixedly connected to the end of the movable rod 10. The second clamping plate 12 is located to the side of the first clamping plate 11. The second clamping plate 12 and the first clamping plate 11 are fixedly connected by two locking screws 16. The ends of the first clamping plate 11 and the second clamping plate 12 that are close to each other are respectively provided with matching grooves 17, which are compatible with the outer shell of the welding gun.

[0022] The first linear drive mechanism consists of a first threaded rod 4, a fixed vertical plate 5, and a first motor 6. Fixed vertical plates 5 are fixedly installed on both sides of the upper end of the guide rail 2. The first threaded rod 4 is rotatably installed between the two fixed vertical plates 5. The first motor 6 is fixedly installed at the end of one fixed vertical plate 5 away from the first threaded rod 4. The output shaft of the first motor 6 is fixedly connected to the first threaded rod 4. The slider 3 is threadedly sleeved on the outer surface of the first threaded rod 4.

[0023] When in use, starting motor 6 drives threaded rod 4 to rotate, which in turn drives slider 3 to slide on guide rail 2. The movement of slider 3 can drive the welding torch to move in a longitudinal straight line.

[0024] The second linear drive mechanism consists of a second motor 9, a movable block 13, and a second threaded rod 14. The movable block 13 is fixedly connected to the end of the movable rod 10 away from the first clamping plate 11. The movable block 13 is slidably installed in the slide groove 15 opened in the fixed rod 8. The second threaded rod 14 is provided in the slide groove 15. One end of the second threaded rod 14 is rotatably connected to the inner wall of the slide groove 15.

The second motor 9 is fixedly installed at the end of the fixed rod 8 away from the clamping mechanism. The output shaft of the second motor 9 is fixedly connected to the second threaded rod 14.

[0025] When in use, start motor 9 to drive threaded rod 14 to rotate, which in turn drives movable block 13 to move in slide groove 15. Movable block 13 will drive movable rod 10 to move synchronously, thereby driving the welding gun on the clamping mechanism to move in a horizontal straight line.

[0026] A metal baffle 18 is also fixedly installed on the upper end of the fixed base 1.

[0027] The metal baffle 18 can block the sparks that splash during welding, thus preventing damage to the housing of cylinder 7 and the first threaded rod 4.

[0029] When in use, fix the device on the welding table, assemble the various parts of the brake bracket to be welded, place them on the welding table, and fix them by the fixing measures on the welding table, or the staff can manually stabilize them.

[0030] Then place the outer shell of the welding torch between clamp plate 11 and clamp plate 12, and lock it in place with locking screw 16;

[0031] Start motor 6 to drive threaded rod 4 to rotate, which in turn drives slider 3 to slide on guide rail 2. The movement of slider 3 can drive the welding torch to move in a longitudinal straight line. Start motor 9 to drive threaded rod 14 to rotate, which in turn drives movable block 13 to move in slide groove 15. Movable block 13 will drive movable rod 10 to move synchronously, which will drive the welding torch on the clamping mechanism to move in a transverse straight line. Align the tip of the welding torch with the weld seam of the brake bracket, then start the welding torch, and control the welding torch to move along the direction of the weld seam through linear drive mechanism 1 or 2, so as to quickly achieve welding of the weld seam.

[0032] It should be noted that the above-mentioned device mainly assists workers in welding straight seams; other shapes of seams require other auxiliary tooling.
