Description

Technical Field

[0001] The utility model relates to the field of brake disc production, in particular to a pre-treatment device for brake discs. Background Art

[0002] Simply put, a brake disc is a circular plate that rotates when the vehicle is moving. The brake caliper clamps the brake disc to generate braking force. When stepping on the brake, it clamps the brake disc to play a role in decelerating or stopping the vehicle. In the process of automobile manufacturing and maintenance, the cleaning of the brake disc is an important link.

[0003] The existing cleaning process usually includes a single cleaning step, which is difficult to thoroughly remove the grease and dirt on the surface of the brake disc. Especially when the grease and dirt are unevenly distributed and have inconsistent thickness, it is easy to result in poor cleaning effect of a single cleaning step, affecting subsequent processing and use. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a pre-treatment device for brake discs that can clean the brake disc more efficiently through multi-stage degreasing operations in different zones in view of the current situation of the prior art.

[0005] The utility model is realized through the following technical solutions: The utility model provides a pre-treatment device for brake discs, including a conveying rotating shaft and a carrier. Both ends of the conveying rotating shaft are rotatably connected to the carrier. Its characteristics are as follows: The conveying rotating shaft is divided into a pre-degreasing area and a main degreasing area. One end of the conveying rotating shaft in the pre-degreasing area is sleeved with a first transmission belt, and one end of the conveying rotating shaft in the main degreasing area is sleeved with a second transmission belt.

[0006] By adopting the above technical solution, the material conveying speeds in the pre-degreasing area and the main degreasing area are different, which can initially dissolve and soften the heavy grease and stains on the surface of the brake disc by the pre-degreasing solvent, and then the degreasing agent in the main degreasing area removes the remaining grease and other pollutants after pre-degreasing.

[0007] Furthermore, upper coating pipes and lower coating pipes are evenly arranged in both the pre-degreasing area and the main degreasing area. The upper coating pipes are located above the conveying rotating shaft, and the lower coating pipes are located below the conveying rotating shaft. The upper coating pipes and the lower coating pipes are both inserted with coating spray heads on the side walls facing the conveying rotating shaft.

[0008] By adopting the above technical solution, the coating spray heads can spray the upper and lower surfaces of the brake disc located on the conveying rotating shaft.

[0009] Furthermore, a liquid supply tank is fixedly installed at the connection of the upper coating pipe and the lower coating pipe. The upper coating pipe and the lower coating pipe are both inserted into the liquid supply tank, and a communication pipe is inserted into one side wall of the liquid supply tank.

[0010] By adopting the above technical solution, it is ensured that the degreasing agent can be replenished.

[0011] Furthermore, a cleaning rack is fixedly installed on one side of the main degreasing area of the carrier rack. Cleaning nozzles are arranged on the side wall of the inner side of the cleaning rack facing the conveying rotating shaft.

[0012] By adopting the above technical solution, after the water source is connected, the cleaning rack can clean the brake disc that has completed the degreasing treatment through the cleaning nozzles.

[0013] Furthermore, an air supply pipe is arranged on one side of the cleaning rack. The air supply pipe is fixedly connected to the cleaning rack through a bracket, and a plurality of air knives are evenly distributed at the lower end of the air supply pipe.

[0014] By adopting the above technical solution, the air knives can clean the water stains on the brake disc.

[0015] The utility model has the following beneficial effects compared with the prior art:

[0016] By setting a pre-degreasing area, a first transmission belt, a main degreasing area, a second transmission belt, a coating nozzle, a cleaning rack and air knives, the brake disc pretreatment device of the utility model can include four main areas: pre-degreasing, main degreasing, water washing and drying treatment. The brake disc passes through these areas in sequence, is treated for a specific time in each area, and through two-step degreasing operations, can perform a more comprehensive and in-depth cleaning on the grease and dirt on the surface of the brake disc, ensure the cleaning effect, and avoid affecting subsequent processing and use.

[0023] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] As Figures 1 - 3 shown, the brake disc pre-treatment device in this embodiment includes a conveyor rotating shaft 1 and a carrier 2. Both ends of the conveyor rotating shaft 1 are rotatably connected to the carrier 2. Its characteristics are: there are a pre-degreasing area 3 and a main degreasing area 4 on the conveyor rotating shaft 1. One end of the conveyor rotating shaft 1 located in the pre-degreasing area 3 is sleeved with a first drive belt 301, and one end of the conveyor rotating shaft 1 located in the main degreasing area 4 is sleeved with a second drive belt 401. The first drive belt 301 can keep the conveyor rotating shaft 1 in the pre-degreasing area 3 at a certain rotation speed, and the second drive belt 401 can keep the conveyor rotating shaft 1 in the main degreasing area 4 at a certain rotation speed, so that the conveying speeds of the brake discs in the pre-degreasing area 3 and the main degreasing area 4 are inconsistent. When the oil stains on the brake disc are thick and unevenly distributed, the conveying speed of the pre-degreasing area 3 can be controlled to slow down appropriately, so that the pre-degreasing agent can have a longer dissolution reaction time. After the pre-degreasing is completed, the main degreasing agent sprayed in the main degreasing area 4 can wash away the pre-degreasing agent and grease that have completed the dissolution reaction, and at the same time coat the main degreasing agent for more comprehensive and deep dissolution, so as to ensure the effect of the degreasing operation.

[0025] As Figure 2 shown, both the upper coating pipe 5 and the lower coating pipe 6 are inserted with coating spray heads 9 on the side walls facing the conveyor rotating shaft 1. A liquid supply tank 7 is fixedly installed at the connection of the upper coating pipe 5 and the lower coating pipe 6. The upper coating pipe 5 and the lower coating pipe 6 are both inserted into the liquid supply tank 7. A connecting pipe 8 is inserted into one side wall of the liquid supply tank 7. The liquid supply tank 7 is connected to an external liquid supply device through the connecting pipe 8, so as to ensure the continuous spraying effect of the coating spray 9.

[0026] As Figure 3 and Figure 4As shown, a cleaning rack 10 is fixedly installed on one side of the main degreasing area 4 of the carrier rack 2. Cleaning nozzles 11 are arranged on the side wall of the inner side of the cleaning rack 10 facing the conveying rotating shaft 1. An air supply pipe 12 is arranged on one side of the cleaning rack 10. The air supply pipe 12 is fixedly connected to the cleaning rack 10 through a bracket 13. A plurality of air knives 14 are evenly distributed at the lower end of the air supply pipe 12. The cleaning rack 10 can provide cleaning liquid for the cleaning nozzles 11 by connecting to external equipment, so that the cleaning nozzles 11 can rinse the main degreasing agent that has completed the degreasing operation, and then be dried by the air knives 14 to complete the pretreatment operation of the brake disc.

[0027] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
