Description

Technical Field

[0001] This utility model belongs to the field of brake disc polishing and grinding, and specifically relates to a debris collection device for brake disc polishing and grinding. Background Technology

[0002] The car brake is the braking device of a car. Almost all car brakes are friction type, which can be divided into two main categories: drum type and disc type. The rotating element of the common disc brake is the rotating brake disc, with the end face as the working surface. Simply put, the brake disc is a round plate. It also rotates when the car is moving. The brake caliper clamps the brake disc to generate braking force.

[0003] Chinese Patent No. CN221065803U discloses a brake disc polishing device, including a polishing box. The front surface of the polishing box is provided with a sealed door. One end of the polishing box is fixedly connected to a motor box, and the front surface of the motor box is provided with a door. The other end of the polishing box is fixedly connected to a fixed frame. A hydraulic rod is fixedly connected to the top of the inside of the polishing box, and one end of the hydraulic rod is fixedly connected to an upper polishing plate. This invention uses a first pulley and a belt to drive a second pulley and the brake disc body to rotate, thereby using the lower polishing plate to polish the bottom of the brake disc body. By adjusting the position of the upper polishing plate by the hydraulic rod, the top of the brake disc body can be polished. By adjusting the position of the polishing block by the telescopic rod, the side of the brake disc body can be polished. Thus, the brake disc body can be polished in all directions in one go, reducing the number of polishing times and improving polishing efficiency.

[0004] As can be seen from the above structure, the method of using an air suction machine combined with a chip suction pipe to collect polishing debris from brake discs has several drawbacks. First, the debris generated during brake disc polishing combines the hardness of metal particles with an irregular shape. Some debris may also stick together into small pieces due to the high temperature during the polishing process. When these debris enters the chip suction pipe with the airflow, they are very likely to accumulate at the air suction port filter of the air suction machine. Especially when the inner diameter of the chip suction pipe is small or has not been cleaned for a long time, the harder metal debris will get stuck together to form blockage points. The continuous adhesion of debris will quickly reduce the flow cross-section of the pipe, or even completely block it. Blockage will cause a chain of problems. Pipe blockage will cause a sharp drop in debris collection efficiency. A large amount of debris will be scattered in the work area, which will not only pollute the environment and increase the cost of subsequent manual cleaning, but may also affect the polishing accuracy of the brake disc due to debris splashing. The air suction machine will operate in a blocked state for a long time, which will cause insufficient air intake and motor overload, which will not only increase noise, but also shorten the service life of the air suction machine, and may even cause motor overheating failure, seriously affecting the continuity and safety of the overall polishing operation. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a debris collection device for polishing brake discs, so as to solve the problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A device for collecting debris from polishing brake discs includes a collection box, a filter frame fixedly connected to one side of the inside of the collection box, a filter screen fixedly connected to the outside of the filter frame, cleaning components provided on both the inner and outer sides of the filter frame, a suction fan fixedly connected to the outside of the collection box, the suction fan penetrating the collection box and located inside the filter frame, a suction pipe fixedly connected to the upper end of the collection box, a suction head fixedly connected to the other end of the suction pipe, and a suction port opened at the other end of the suction head.

[0008] As a preferred technical solution, the cleaning assembly includes a cleaning motor disposed inside the filter frame, a cleaning rod rotatably connected to the outside of the filter frame, a cleaning plate fixedly connected to the other end of the cleaning rod, cleaning brushes fixedly connected to the inner side of the cleaning plate, the cleaning brushes being movably connected to the filter screen, and the output shaft of the cleaning motor being fixedly connected to the cleaning rod.

[0009] As a preferred technical solution, the outer surface of the filter frame is fixedly connected with a fixing edge, and the outer surface of the fixing edge is provided with a fixing through hole. A fixing screw is inserted into the fixing through hole, and the fixing screw passes through the fixing through hole and is threadedly connected to the collection box.

[0010] As a preferred technical solution, a discharge hole is provided at the lower end of the inside of the collection box, and inclined panels are fixedly connected to both sides of the inside of the collection box, with the inclined panels located on both sides of the discharge hole.

[0011] As a preferred technical solution, the lower end of the collection box is fixedly connected to a threaded discharge pipe, the threaded discharge pipe is connected to the discharge hole, and the outer surface of the threaded discharge pipe is threadedly connected to a threaded sealing cap.

[0012] As a preferred technical solution, both sides of the collection box are fixedly connected to mounting edges, and the outer surface of the mounting edges is provided with mounting through holes. Mounting screws are inserted into the mounting through holes and are threadedly connected to the polishing box through the mounting through holes.

[0013] As a preferred technical solution, the outer side of the collection box is provided with an installation groove, and an observation window is fixedly connected inside the installation groove. The periphery of the observation window is sealed to the inner side of the installation groove.

[0014] In summary, the present invention has the following main advantages:

[0015] First, when the fan starts, a negative pressure environment is created inside the collection box. This negative pressure is transmitted to the suction head through the suction pipe at the top of the collection box, causing the suction port of the suction head to generate a strong suction force. Debris generated from polishing the brake disc is drawn into the suction pipe through the suction port under the action of suction force, and then transported into the collection box by the airflow. At this time, the filter frame inside the collection box provides support and restraint, and the filter screen fixed on its outside can accurately intercept debris in the airflow, keeping the debris in the collection box. The filtered clean air is then discharged by the fan, completing the process of adsorption, transportation, filtration, and retention. The complete debris collection process, along with the cleaning components on both the inner and outer sides of the filter frame, can specifically handle debris adhering to the filter screen surface, preventing filter screen clogging and affecting collection efficiency. Through the negative pressure adsorption generated by the suction fan, polishing debris can be quickly sucked directly from the work point into the collection box, preventing debris from scattering in the air or on the work surface, effectively reducing dust pollution, ensuring a clean working environment and the health of operators. Filtration and storage are separated, making cleaning convenient. The filter screen can stably retain debris in the collection box, and subsequent cleaning of the collection box is only required periodically, eliminating the need for frequent handling of pipeline blockage issues.

[0016] Secondly, when the cleaning motor starts, the output shaft drives the cleaning rod to rotate around the rotation point on the outside of the filter frame. The cleaning plate fixed at the other end of the cleaning rod rotates synchronously with the cleaning rod, while the cleaning brush fixed on the inside of the cleaning plate makes active contact with the surface of the filter screen. During the rotation of the cleaning plate, the cleaning brush continuously brushes the surface of the filter screen, peeling off the debris attached to the filter screen from the mesh or the mesh surface, thereby completing the cleaning operation of the filter screen. This achieves automatic cleaning, reduces labor costs, and eliminates the need for manual disassembly of the collection box or removal of the filter screen for cleaning. Cleaning can be completed simply by starting the cleaning motor, greatly reducing manual operation steps and time. It is especially suitable for long-term continuous operation scenarios, avoiding equipment downtime caused by manual cleaning. Attached Figure Description

[0022] Example

[0023] refer to Figures 1 to 4 This embodiment of a brake disc polishing and grinding debris collection device includes a collection box 1. A filter frame 2 is fixedly connected to one side of the inside of the collection box 1. A filter screen 3 is fixedly connected to the outside of the filter frame 2. Cleaning components 4 are provided on both the inner and outer sides of the filter frame 2. A suction fan 5 is fixedly connected to the outside of the collection box 1. The suction fan 5 passes through the collection box 1 and is located inside the filter frame 2. A dust suction pipe 6 is fixedly connected to the upper end of the collection box 1. A dust suction head 7 is fixedly connected to the other end of the dust suction pipe 6. A dust suction port 8 is opened at the other end of the dust suction head 7.

[0024] refer to Figure 2 and Figure 4 The cleaning assembly 4 includes a cleaning motor 41 located inside the filter frame 2, a cleaning rod 42 rotatably connected to the outside of the filter frame 2, a cleaning plate 43 fixedly connected to the other end of the cleaning rod 42, and cleaning brushes 44 fixedly connected to the inner side of the cleaning plate 43. The cleaning brushes 44 are movably connected to the filter screen 3, and the output shaft of the cleaning motor 41 is fixedly connected to the cleaning rod 42. When the cleaning motor 41 is started, the output shaft will drive the cleaning rod 42 to rotate around the rotation point on the outside of the filter frame 2. The cleaning plate 43 fixed at the other end of the cleaning rod 42 will rotate synchronously with the cleaning rod 42, and the cleaning brushes 44 fixed on the inner side of the cleaning plate 43 will make movable contact with the surface of the filter screen 3. During the rotation of the cleaning plate 43, the cleaning brushes 44 will continuously brush the surface of the filter screen 3, peeling off the debris attached to the filter screen 3 from the mesh or mesh surface, thereby completing the cleaning operation of the filter screen 3.

[0025] refer to Figure 4 The outer surface of the filter frame 2 is fixedly connected with a fixing edge 18. The outer surface of the fixing edge 18 is provided with a fixing through hole 19. A fixing screw 20 is inserted into the fixing through hole 19. The fixing screw 20 passes through the fixing through hole 19 and is threadedly connected to the collection box 1. The filter frame 2 can be installed during use through the fixing through hole 19 and the fixing screw 20. The installation is more convenient during disassembly because it is installed by threaded connection.

[0026] refer to Figure 2The lower end of the collection box 1 has a discharge hole 12. Both sides of the inside of the collection box 1 are fixedly connected to inclined panels 13, which are located on both sides of the discharge hole 12. The inclined surface of the inclined panels 13 prevents debris from accumulating on both sides of the inner wall of the collection box 1. The debris falling on the inclined panels 13 will slide down naturally along the inclined direction of the inclined panels 13 under its own gravity. The design of the inclination angle and position of the inclined panels 13 on both sides can guide the debris from different areas inside the collection box 1 to the discharge hole 12 in the middle, so as to achieve the concentrated collection of debris.

[0027] refer to Figure 2 The lower end of the collection box 1 is fixedly connected to a threaded discharge pipe 14, which is connected to the discharge hole 12. The outer surface of the threaded discharge pipe 14 is threadedly connected to a threaded sealing cap 15. When it is necessary to discharge the collected debris, simply rotate the threaded sealing cap 15 in the opposite direction so that the sealing cap moves upward along the threaded structure of the threaded discharge pipe 14 and gradually disengages from the sealing fit with the discharge pipe until the lower end of the discharge pipe is fully opened. At this time, the debris remaining in the threaded discharge pipe 14 will be discharged naturally from the open discharge pipe port under its own gravity, making it convenient for operators to collect or centrally process it with a container.

[0028] refer to Figure 1 The collection box 1 is fixedly connected to two sides with mounting edges 9. The outer surface of the mounting edge 9 is provided with mounting through holes 10. Mounting screws 11 are inserted into the mounting through holes 10 and are threaded through the mounting through holes 10 to the polishing box. The collection box 1 can be installed in use through the mounting through holes 10 and mounting screws 11. The threaded connection makes it more convenient to install and disassemble.

[0029] refer to Figure 3 The outer side of the collection box 1 is provided with an installation groove 16, and an observation window 17 is fixedly connected inside the installation groove 16. The periphery of the observation window 17 is sealed to the inner side of the installation groove 16. In actual use, the operator does not need to open the collection box 1 or stop the machine to disassemble it. He can directly monitor the real-time status inside the collection box 1 through the transparent observation window 17. He can clearly see the amount of debris accumulated in the collection box 1 and determine whether the debris needs to be discharged through the threaded discharge pipe 14. This avoids the filter efficiency of the filter screen 3 or the blockage of the discharge hole 12 due to excessive debris accumulation. The operator can also observe the cleanliness of the surface of the filter screen 3 and promptly detect whether there is a problem of excessive debris adhesion so that the cleaning component 4 can be started to clean the filter screen.

[0030] Operating principle and advantages: During use, the collection box 1 is installed, and then the suction fan 5 is started, creating a negative pressure environment inside the collection box 1. This negative pressure is transmitted through the suction pipe 6 at the top of the collection box 1 to the suction head 7, causing the suction port 8 of the suction head 7 to generate strong suction. Debris generated from polishing the brake disc is drawn into the suction pipe 6 through the suction port 8 under the suction force, and then transported to the collection box 1 by the airflow. At this time, the filter frame 2 inside the collection box 1 provides support and limitation, and the filter screen 3 fixed on its outer side accurately intercepts debris in the airflow, keeping the debris inside the collection box 1. The filtered clean air is then discharged by the suction fan 5, completing the complete debris collection process of adsorption, transportation, filtration, and retention. During use, the cleaning motor 41 is started, and the output shaft drives the cleaning rod 42 to rotate around the rotation point on the outer side of the filter frame 2. The cleaning plate 43 fixed at the other end of the cleaning rod 42 rotates synchronously with the cleaning rod 42. The cleaning brush 44 fixed on the inner side of the cleaning plate 43 makes active contact with the surface of the filter screen 3. During the rotation of the cleaning plate 43, the cleaning brush 44 continuously brushes the surface of the filter screen 3, peeling the debris attached to the filter screen 3 from the mesh or mesh surface, thereby completing the cleaning operation of the filter screen 3 and realizing automatic cleaning. Finally, when it is necessary to discharge the collected debris, simply rotate the threaded sealing cover 15 in the opposite direction, so that the sealing cover moves upward along the threaded structure of the threaded feed tube 14, gradually disengaging from the sealing fit with the feed tube until the lower end of the feed tube is fully opened. At this time, the debris remaining in the threaded feed tube 14 will be naturally discharged from the open feed tube port under its own gravity, making it convenient for operators to collect or centrally process it with a container.
