Description

Technical Field

[0001] The present application relates to the field of automobile brake system manufacturing technology, and in particular to a brake assembly production line and a control method. Background Art

[0002] Drum brakes, also known as drum brakes, are a traditional automobile brake assembly. The main working principle is to apply pressure inside the brake drum to create friction between the brake shoe and the inner wall of the brake drum, thereby generating braking force. When the driver steps on the brake pedal, pressure is transmitted through the hydraulic or mechanical system to push the brake shoe to expand outward, causing it to contact the brake drum, generating friction, thereby slowing down or stopping the vehicle.

[0003] Drum brakes are mainly composed of the following parts: brake drum: a metal cylindrical component, usually made of cast iron, installed on the wheel, and rotate synchronously with the wheel in the assembly of automobile drum brakes; brake shoe: a component that contacts the inner wall of the brake drum to produce friction, usually made of friction material; brake shoe: a metal part that supports the brake shoe, fixed on the brake base plate; brake base plate: a component that fixes the brake shoe and the brake shoe, installed on the axle; brake wheel cylinder: in the hydraulic braking system, the pressure of the brake pedal is converted into hydraulic pressure to push the brake shoe; return spring: an elastic element that makes the brake shoe return to its original position after the brake is released. Therefore, in the production process of drum brakes, workers are required to assemble the above components. In order to improve the refinement of the operation, specific workers are often responsible for the assembly of specific parts, and then handed over to other workers for the assembly of the following parts.

[0004] However, the existing brake assembly production line has problems such as low efficiency, low precision and high labor intensity in the process of transportation and manual operation. With the development of automation technology, there is an urgent need for a brake assembly production line that can improve the automation level of brake assembly, so as to reduce labor costs and improve product quality and production efficiency. Summary of the invention

[0005] In order to overcome the above-mentioned deficiencies of the prior art, the present application provides a brake assembly assembly production line, which can achieve efficient distribution of brake assembly positioning plates, reduce the time and labor intensity of manual handling, and improve production efficiency.

[0009] By adopting the above technical solution, the support mechanism can position the chain to prevent it from shaking up and down, thereby ensuring the stability of the brake assembly positioning plate. In particular, as the main support of the operating platform, when workers assemble the brake assembly, it is necessary to bear various loads in the assembly operation. If there is up and down shaking, it will seriously affect the progress and accuracy of the assembly, and thus affect the assembly quality. The support mechanism can effectively bear the vertical load of the conveyor chain, ensure the stability and reliability of the conveyor chain during operation, and avoid deformation or damage of the chain due to gravity, thereby extending the service life of the equipment and improving production efficiency and product quality.

[0015] By adopting the above technical solution, the power push rod can realize the action of slow recovery after rapid downward movement, which improves the precise positioning ability of the brake assembly positioning plate at the designated workstation and ensures the accuracy and consistency of each process. Specifically: the two chambers formed by the piston at the lower end of the push rod of the power push rod and the inner cavity of the cylinder sleeve realize the rapid entry and slow discharge of compressed air through the setting of the first vent and the second vent, ensuring the rapid downward movement and slow recovery of the positioning wheel; the first vent is connected to the compressed air switch through a pipeline, so that after the process on the operating station is completed, the power push rod can be quickly started when the compressed air switch is stepped on, improving work efficiency; the aperture of the second vent is smaller than the first vent, ensuring the slow discharge of air in the second chamber, so that the positioning wheel slowly recovers, avoiding vibration and instability caused by rapid recovery; the third vent is provided with a plug, which can facilitate the installation of the push rod and the cylinder sleeve, and seal the second chamber to ensure the air tightness of the second chamber, so that when the piston moves downward, the second chamber has a reduced volume, which increases the pressure and provides elastic power for the later recovery of the piston.

Specifically: the design of the slow-down plate and the first bottom plate in the lowering platform, as well as the first conveyor belt set on the slow-down plate, ensure the stability and reliability of the brake assembly positioning plate during the downward movement. The use of the second guide rod further improves the movement accuracy of the slow-down plate, ensuring the accurate position of the brake assembly positioning plate during the downward movement; the setting of the first lifting mechanism, through the cooperation of the electric telescopic rod and the transmission chain, realizes the precise lifting and lowering of the slow-down plate, ensuring the smooth transition of the brake assembly positioning plate between the lowering platform and the lower return and distribution device; the structure of the upper platform is similar to that of the lower platform to reduce the design and production costs. In general, this design not only improves the degree of automation of the entire production line, but also significantly improves production efficiency and product quality stability.

[0021] By adopting the above technical solution, the first lifting mechanism can accurately control the up and down movement of the slow-descent plate through the cooperation of the electric telescopic rod and the transmission chain, and can change the control position of the electric telescopic rod, so that in a narrow space of the downward moving platform, the slow-descent plate can be lowered to the bottom plate to adapt to the lower return distribution device.
