Description

Technical Field

[0001] This invention relates to the field of brake disc grinding devices, and more particularly to a high-efficiency cooling grinding device for brake discs. Background Technology

[0002] Brake disc grinding machines are typically equipped with airflow generators or fans to generate the required airflow. The generated airflow is guided through pipes or guide devices to the working area of ​​the brake disc grinding to remove heat from the grinding area.

[0003] Existing high-efficiency cooling grinding devices for brake discs often use a cold air blower to cool the outside air when processing brake discs that cannot adapt to coolant. The air is then blown into the device through pipes to carry away and neutralize the heat generated by the grinding process.

[0004] Existing high-efficiency cooling grinding devices for brake discs, while capable of removing heat with cool air, have a significant impact on cooling effectiveness due to the location of the air outlet. Adjusting the outlet position requires releasing the limiting mechanism with a screwdriver, which increases operational complexity. Furthermore, replacing grinding tools necessitates dismantling the pipes to prevent obstruction. Therefore, a high-efficiency cooling grinding device for brake discs is proposed to address these issues. Summary of the Invention

[0005] To overcome the above shortcomings, the present invention provides a brake disc high-efficiency cooling grinding device, which aims to improve the problems of complicated air outlet position adjustment and pipes that may block tool replacement in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency cooling and grinding device for brake discs, comprising a housing, a sliding door slidably connected to the front of the housing, an air intake assembly fixedly connected to the top of the housing, an air outlet fixedly connected to the lower end of the air intake assembly, a sliding shaft fixedly connected to the tail of the air outlet, a snap-fit ​​block elastically connected to the upper end of the sliding shaft via a spring, fixed plates slidably connected to both ends of the upper part of the sliding shaft, a connecting rod fixedly connected to the side end of the fixed plate, a sliding column fixedly connected to the upper middle part of the connecting rod, a sliding assembly slidably connected to the outside of the sliding column, and a grinding assembly fixedly connected to the lower part of the housing.

[0007] As a further description of the above technical solution: The sliding assembly includes a sliding sleeve, the interior of which is elastically connected to the upper part of the sliding column by a second spring, and a positioning block is slidably connected to the lower part of the sliding sleeve. Two sets of positioning blocks are provided, and the two sets of positioning blocks are elastically connected to each other by a third spring.

[0008] As a further description of the above technical solution: The air intake assembly includes a cooler, the lower end of which is fixedly connected to a telescopic tube. The lower end of the cooler and the upper end of the telescopic tube are both fixedly connected to the upper right side of the housing. The lower part of the telescopic tube is fixedly connected to the inside of the side end of the air outlet.

[0009] As a further description of the above technical solution: The grinding assembly includes a cutting tool, the middle of which is in external contact with a clamping device. The lower end of the cutting tool is rotatably connected to the inner bottom of the housing, and the lower part of the clamping device is slidably connected to the inside of the housing.

[0010] As a further description of the above technical solution: The upper part of the sliding shaft is slidably connected to the inside of both ends of the connecting rod.

[0011] As a further description of the above technical solution: The lower end of the first spring is fixedly connected to the outside of the snap-fit ​​block, and the other end of the first spring is fixedly connected to the inside of the upper end of the sliding shaft. The lower part of the snap-fit ​​block is slidably connected to the inside of both ends of the connecting rod.

[0012] As a further description of the above technical solution: The upper end of the sliding sleeve is fixedly connected to the upper end of the outer shell, one end of the second spring is fixedly connected to the upper end of the sliding sleeve, and the other end of the second spring is fixedly connected to the upper part of the sliding column.

[0013] As a further description of the above technical solution: The external slidable connection of the positioning block is to the upper interior of the sliding column, and both ends of the spring are fixedly connected to the external side of the positioning block.

[0014] The present invention has the following beneficial effects: 1. In this invention, by pulling the upper end of the snap-fit ​​block, the limiting position of the connecting rod on the sliding shaft can be released. Then, by sliding the sliding shaft, the air outlet can be adjusted. This allows for easy adjustment of the distance between the air outlet and the grinding part, so that when the rotation speed changes, it can be quickly adjusted to achieve the best cooling effect.

[0015] 2. In this invention, when it is necessary to replace or maintain the cutting tools, the positioning block can be pressed, and then the sliding column can be slid upward to slide the air outlet to the upper part of the inner shell so that it will not affect the operation.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Reference Figures 1-3 One embodiment of the present invention provides a high-efficiency cooling and grinding device for brake discs, comprising a housing 1, a sliding door 2 slidably connected to the front of the housing 1, the housing 1 and the sliding door 2 sealing the entire device to prevent debris from flying out, an air intake assembly fixedly connected to the top of the housing 1, the air intake assembly cooling the air before discharging it into the air outlet 6, the air intake assembly including a cooler 3, the cooler 3 drawing outside air into a telescopic pipe 5 and cooling it, the lower end of the cooler 3 fixedly connected to the telescopic pipe 5, the telescopic pipe 5 being F-shaped, and... Both the lower and upper ends are telescopic, which facilitates the movement of the air outlet 6. The lower end of the air cooler 3 and the upper end of the telescopic tube 5 are fixedly connected to the upper right end of the outer casing 1. The outer casing 1 keeps the telescopic tube 5 and the air cooler 3 fixed. The lower part of the telescopic tube 5 is fixedly connected to the inside of the side end of the air outlet 6. The cold air can be discharged into the air outlet 6 through the telescopic tube 5. The lower end of the air intake component is fixedly connected to the air outlet 6. The air outlet 6 is in an inclined state and is flush with the middle of the tool 7, which can blow the cold air evenly to the grinding part to carry away the heat and cool it down.

[0020] Reference Figures 4-6 A sliding shaft 8 is fixedly connected to the tail of the air outlet 6. The sliding shaft 8 can drive the air outlet 6 to slide horizontally. The distance of the air outlet 6 can be adjusted according to the grinding speed and material to maintain the best air cooling effect. The upper part of the sliding shaft 8 is slidably connected to the two ends of the connecting rod 9. The connecting rod 9 restricts the sliding shaft 8 to slide horizontally. The upper end of the sliding shaft 8 is elastically connected to a locking block 10 by a spring-16. The locking block 10 is composed of a square shape and an upper U-shaped rod. The U-shaped rod facilitates the upward sliding of the locking block 10. The lower end of the spring-16 is fixedly connected to the outside of the locking block 10, and the other end of the spring-16 is fixedly connected to the upper end of the sliding shaft 8. Inside, spring 16 keeps the locking block 10 fixed inside the connecting rod 9. The lower part of the locking block 10 is slidably connected to the two ends of the connecting rod 9. The locking block 10 can be locked in different positions to adjust the position of the air outlet 6. The upper two ends of the sliding shaft 8 are slidably connected to the fixing plate 17. The fixing plate 17 restricts the sliding shaft 8 to slide horizontally relative to the connecting rod 9. The side end of the fixing plate 17 is fixedly connected to the connecting rod 9. The connecting rod 9 can keep the two ends of the sliding shaft 8 sliding up and down at the same time. The middle upper part of the connecting rod 9 is fixedly connected to the sliding column 15. The sliding column 15 can drive the connecting rod 9 to slide up and down. The outside of the sliding column 15 is slidably connected to the sliding component.

[0021] Reference Figures 1-2 A grinding assembly is fixedly connected to the lower part of the outer shell 1. The grinding assembly can grind the outer surface of the brake disc smooth. The grinding assembly includes a cutting tool 7, which is circular and can grind the outer surface of the brake disc. A clamping device 4 is in contact with the middle of the cutting tool 7. The clamping device 4 can clamp the brake disc and keep it relatively fixed. The lower end of the cutting tool 7 is rotatably connected to the bottom of the inner part of the outer shell 1. The outer shell 1 restricts the cutting tool 7 to rotate only. The lower part of the clamping device 4 is slidably connected to the inner part of the outer shell 1.

[0022] Reference Figures 2-3The sliding assembly includes a sliding sleeve 14, which fixes the position of the sliding post 15 and ensures that it can only slide vertically. The interior of the sliding sleeve 14 is elastically connected to the upper part of the sliding post 15 via a second spring 13. The second spring 13 allows the sliding post 15 to slide upwards easily when the positioning block 11 is no longer engaged. This allows the sliding shafts 8 at both ends to slide upwards quickly via the connecting rod 9, preventing them from obstructing the maintenance and replacement of the tool 7. The upper end of the sliding sleeve 14 is fixedly connected to the interior of the upper end of the outer shell 1, which restricts the sliding sleeve 14 to remain stationary. One end of the second spring 13 is fixedly connected to the interior of the upper end of the sliding sleeve 14, and the other end of the second spring 13 is fixed... A fixed connection is made to the upper part of the sliding column 15. Spring 2 13 keeps the sliding column 15 in a pulling state. The lower part of the sliding sleeve 14 is slidably connected to a positioning block 11. The positioning block 11 is T-shaped and can be restricted by the sliding column 15 so that it cannot slide out completely. There are two sets of positioning blocks 11. The two sets of positioning blocks 11 are elastically connected to the outside of the two sets of positioning blocks 11 by spring 3 12. The protruding part of the positioning block 11 is an arc surface, which can facilitate the sliding column 15 to slide up. The outside of the positioning block 11 is slidably connected to the upper end of the sliding column 15. The positioning block 11 can keep the air outlet 6 in the blowing position by snapping it in place. Both ends of spring 3 12 are fixedly connected to the outside of the side end of the positioning block 11. Spring 3 12 keeps the positioning block 11 in a sliding state.

[0023] Working principle: Push open the sliding door 2, fix the brake disc on the clamping device 4, slide the sliding door 2 to close, and then slide the clamping device 4 to make its surface contact the tool 7. The tool 7 and the clamping device 4 rotate to perform grinding. At this time, the cold air blower 3 starts to cool the air and discharge it into the telescopic pipe 5. The cold air enters the air outlet 6 through the telescopic pipe 5 and is then discharged to the grinding area to carry away the heat. When it is necessary to adjust the position of the air outlet 6 to adjust the cooling effect, pull the upper end of the locking block 10 so that the lower part of the locking block 10 slides out of the connecting rod 9 to compress the spring 16. Then slide the sliding shaft 8. The sliding shaft 8 drives the two sets of air outlets 6 to slide to the appropriate position and then release the locking block 10 so that it springs back to its original position. The pressure of spring 16 slides into the connecting rod 9 and remains fixed. When the tool 7 needs to be replaced or maintained, press the positioning block 11 so that the positioning block 11 slides into the sliding sleeve 14. Then slide the sliding column 15 upward. The sliding sleeve 14 squeezes the positioning block 11 into the sliding column 15 and squeezes the spring 3 12. Spring 2 13 pulls the sliding column 15. The sliding column 15 drives the connecting rod 9 to slide upward. The connecting rod 9 drives the air outlet 6 to slide upward until it is stable. Replace and maintain the tool 7. Then pull down the sliding column 15. The sliding column 15 pulls the spring 2 13. When it reaches the air outlet position, the positioning block 11 slides out under the push of spring 3 12 until it can no longer slide. At this time, the position of the air outlet 6 is fixed.
