TECHNICAL FIELD

[0001] The present application relates to the technical field of welding equipment, in particular to a brake shoe with a brake shoe assembly welding equipment. BACKGROUND

[0002] The brake shoe refers to the accessory that is pushed outward to expand and press the brake drum to play the brake effect under the action of the brake cam or push rod, is installed on the brake drum, and is one of the key safety parts in the automobile brake system. When the brake shoe is manufactured, the web plate and the face plate need to be welded together, and the web plate and the face plate are both arc-shaped. Therefore, the welding equipment needs to perform arc-shaped welding to weld them.

[0003] For the current welding equipment, such as the brake shoe welding machine disclosed in Chinese patent publication No. "CN109676277A", when the web plate and the face plate are welded, the two are welded by arc-shaped welding. However, after welding is completed, a certain amount of welding slag is left, which needs to be removed after welding is completed for grinding. Not only is time and manpower wasted, but the welding slag has been cooled for a long time and is not easy to grind, which consumes more grinding time and is very inconvenient to use. Accordingly, the present application proposes a brake shoe with a brake shoe assembly welding equipment. SUMMARY

[0004] The purpose of the present application is to solve the problems existing in the prior art and to provide a brake shoe with a brake shoe assembly welding equipment.

[0005] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: A brake shoe with a brake shoe assembly welding equipment, comprising a stable base, a mounting rack plate and a transverse partition plate, the mounting rack plate is fixedly arranged on the top of the stable base, the transverse partition plate is fixedly arranged on the top of the mounting rack plate, and the transverse partition plate is provided with a driving part; The driving part comprises a sliding plate and a slider, wherein the slider is fixedly arranged on the bottom of the sliding plate, and the driving part drives the slider inside the slider to slide up and down by means of an electric drive; A fixed plate is fixedly arranged on the sliding member in the slider, one side of the fixed plate is fixedly provided with an equipment bin, the bottom of the equipment bin is provided with a welding part, the welding part comprises a driving shaft and a welding head, and the welding part drives the welding head to move horizontally along the arc-shaped curve by the arc-shaped rotation of the driving shaft; A transmission grinding part is arranged in the equipment bin, the transmission grinding part is composed of a transmission part and a grinding part, the transmission part comprises a threaded rod, the transmission part drives the threaded rod in the other direction to rotate by the rotation of the driving shaft, so as to drive the nut on the threaded rod to slide horizontally by the rotation of the threaded rod; The polishing part comprises a torsion spring, and the polishing part is compressed by the rotation of the driving shaft to make the torsion spring generate a compression torsion force.

[0006] Preferably, the transmission part further comprises a second guide rod, and a clamping part is arranged on the second guide rod.

[0007] Preferably, a side of the transmission part is linked with a gas jet part, and the gas jet part comprises a gas bag.

[0008] Preferably, the clamping part pushes the clamping block by the lateral sliding of the nut in the transmission part to make the clamping block slide into and out of the surface of the second guide rod.

[0009] Preferably, the gas bag is composed of a plurality of trapezoidal gas bags connected with each other and is made of foldable and flexible material.

[0010] Preferably, the clamping part and the gas jet part are connected by the transmission part.

[0011] Preferably, one end of the torsion spring is fixedly connected with the driving shaft, and the other end of the torsion spring is fixedly connected with the supporting part of the polishing part.

[0012] Preferably, one side of the supporting part of the polishing part is close to one side of the supporting part of the welding part.

[0013] The present application has the following advantages: 1. By arranging the polishing part, the driving shaft is rotated to drive the welding head to move along the arc curve to complete the welding operation, and the transmission polishing part is driven to operate to generate a torsion force by the compression of the torsion spring by the rotation of the driving shaft.

[0014] 2. The locking part in the transmission unit drives the nut to slide laterally through the threaded rod, pushing the locking block to slide into or out of the second guide rod, thereby achieving a blocking and fixing position of the grinding part. This design can stably lock the position of the grinding part during grinding operations, preventing grinding displacement caused by equipment vibration. When grinding is completed, the locking block retracts, automatically and quickly grinding the part without affecting the operation of other components. This not only ensures the structural stability of key processes, but also reduces the risk of misoperation through mechanical limiting, thus improving the safety of equipment operation.

[0015] 3. The jet unit linked to the transmission unit drives the pressure plate to slide through the threaded rod, causing the air bladder to fold and compress or expand and stretch, generating jet and suction actions. During welding and grinding, the jet can promptly blow away metal debris, fumes and grinding dust at the weld, preventing impurities from adhering and affecting the welding quality or scratching the workpiece surface, reducing wear on internal parts of the equipment, extending the service life of the equipment, and improving the working environment.

[0016] 4. The rotation of the drive shaft synchronously drives the operation of multiple components such as the welding part, transmission grinding parts, and air jetting part. The drive shaft not only drives the welding head to move in an arc, but also drives the threaded rod to rotate, compress the torsion spring, and link the air jetting part through the transmission structure, realizing one source for multiple drives. This design reduces the number of independent power units, reduces energy consumption, makes the equipment structure more compact, saves installation space, and the coordinated operation of each component improves the smoothness of the overall operation.
