Description

Technical Field

[0001] This utility model belongs to the field of brake disc polishing technology, specifically relating to a new type of polishing device for processing automotive brake discs. Background Technology

[0002] Brake discs are the core component of a car's braking system. They achieve deceleration or stopping by generating friction through the clamping of brake calipers. They are mainly made of gray cast iron and come in two structures: solid discs and air-cooled discs.

[0003] After the brake disc is cast, its surface has a lot of burrs, which need to be polished by polishing equipment. Existing polishing equipment generates a lot of flying debris during the polishing process, which not only pollutes the working environment, but is also easy to be inhaled by workers, causing damage to their health. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of polishing device for processing automotive brake discs that is simple in structure and reasonably designed in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A novel polishing device for processing automotive brake discs includes a frame with two symmetrically mounted side plates on the top. A polishing structure is connected between the two side plates. Four guide rods are matrix-mounted on the upper surface of one end of each side plate. An adjustment structure is slidably connected to each guide rod. Two sliding rods pass through the adjustment structure. A tension spring is sleeved on the upper end of each sliding rod, with its top fixed to the sliding rod and its bottom fixed to the adjustment structure. A limit structure is fixedly mounted on the lower end of each sliding rod, with a protective cover fixed to the lower surface of the adjustment structure at its top. A support plate is fixedly mounted on the top of each guide rod, and a drive device for sliding the adjustment structure is mounted on the support plate.

[0007] As a further optimization of this utility model, the polishing structure includes two drive shafts rotatably connected to the ends of the side plates, and the same polishing abrasive belt is sleeved on the two drive shafts. The polishing abrasive belt is connected to the drive shafts in a driving connection, and a motor that drives the drive shaft to rotate is installed on one of the side plates.

[0008] As a further optimization of this utility model, the adjustment structure includes a movable plate disposed between the four guide rods. Both sides of the movable plate extend outward to form ear plates. Guide holes are provided on the ear plates. The ear plates are sleeved on the corresponding guide rods through the guide holes and are slidably connected to the guide rods.

[0009] As a further optimization of this utility model, the limiting structure is a stop block fixedly installed on the bottom end of the slide bar. The two stop blocks are symmetrically arranged, and the adjacent sides of the two stop blocks are arc-shaped. The top of the stop block extends outward to form a pressure block, and the distance between the bottom wall of the pressure block and the bottom of the frame is greater than the thickness of the brake disc.

[0010] As a further optimization of this utility model, the protective cover has an opening on the side near the input end of the polishing belt, and the protective cover is sealed on the side near the output end of the polishing belt.

[0011] As a further optimization of this utility model, the driving device includes a cylinder fixedly installed on the upper surface of the support plate, a piston rod is installed on the cylinder, and the bottom end of the piston rod movably passes through the support plate and is fixed to the upper surface of the movable plate.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. During use, the brake disc is pressed against the upper surface of the polishing belt by the stop and pressure block under the movable plate through the cylinder. Then, the motor is started to drive the polishing belt to rotate, rubbing the brake disc to polish it. Because the stop is equipped with a protective cover that is fixed to the lower surface of the movable plate at the top, and one end of the protective cover is sealed, the polishing debris generated will splash towards the sealed end of the protective cover due to the inertia of the rotation direction of the polishing belt. The splashed debris will fall back onto the polishing belt due to the obstruction of the protective cover, so as to prevent the debris from splashing and easily polluting the working environment and affecting the health of the workers.

[0014] 2. A gap is left between the bottom of the protective cover sealing end and the upper surface of the polishing belt. The debris falling on the polishing belt will continue to be transported with the polishing belt until it is discharged from the output end of the polishing belt. Users only need to place an external collection structure below the output end of the polishing belt to achieve automatic collection of debris without the need for manual cleaning by the user, which is convenient for users.

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example

[0022] like Figure 1 - Figure 4 As shown, a new type of polishing device for processing automotive brake discs includes a frame 1. Two side plates 2 are symmetrically mounted on the top of the frame 1. A drive shaft 3 is rotatably connected between the ends of the two side plates 2. The same polishing belt 4 is sleeved on the two drive shafts 3. The polishing belt 4 is connected to the drive shaft 3. A motor 5 that drives the drive shaft 3 to rotate is installed on one of the side plates 2. When the motor 5 is started, the motor 5 drives the drive shaft 3 to rotate, causing the polishing belt 4 to rotate at high speed. At this time, one side of the brake disc is placed against the polishing belt 4, and the brake disc can be polished and ground using the polishing belt 4.

[0023] A crossbeam is fixedly connected to the upper surface of one end of the side plate 2. Four guide rods 6 are matrixed and installed on the crossbeam and the side plate 2. A movable plate 7 is set between the four guide rods 6. Both sides of the movable plate 7 extend outward to form ear plates 8. Guide holes are opened on the ear plates 8. The ear plates 8 are sleeved on the corresponding guide rods 6 through the guide holes, so that the movable plate 7 is slidably connected to the guide rods 6 through the ear plates 8 and the guide holes, which facilitates the adjustment of the position of the movable plate 7.

[0024] Two sliding rods 9 slide through the movable plate 7. A tension spring 10 is fitted on the end of the sliding rod 9 located above the movable plate 7. The top end of the tension spring 10 is fixed to the sliding rod 9, and the bottom end of the tension spring 10 is fixed to the movable plate 7. When the bottom of the sliding rod 9 is pressed, it will push the sliding rod 9 to move upward, thereby pulling the tension spring 10 to stretch. The tension spring 10 in the stretched state can provide a reverse force.

[0025] Two slide rods 9 are fixedly connected to a stop block 11 at one end below the movable plate 7. The two stop blocks 11 are symmetrically arranged, and the adjacent sides of the two stop blocks 11 are arc-shaped. The stop blocks 11 can fit the arc-shaped side against the side wall of the brake disc to limit the brake disc.

[0026] The top of the stop block 11 extends outward to form a pressure block 12. The downward force applied by the tension spring 10 to the slide rod 9 can push the pressure block 12 down from the upper surface of the brake disc, so that the lower surface of the brake disc is in close contact with the polishing belt 4. With the high-speed rotation of the polishing belt 4, the lower surface of the brake disc can be quickly polished.

[0027] A protective cover 13 is provided around the perimeter of the stop block 11, with its top fixed to the lower surface of the movable plate 7. The protective cover 13 has an opening on the side near the input end of the polishing belt 4 and is sealed on the side near the output end of the polishing belt 4. Since the motor 5 drives the polishing belt 4 to rotate clockwise in conjunction with the transmission shaft 3, the polishing debris will splash towards the sealed end of the protective cover 13 due to inertia. The splashed debris falls back onto the polishing belt 4 after being blocked by the protective cover 13. There is a gap between the bottom of the sealed end of the protective cover 13 and the upper surface of the polishing belt 4. The debris that falls onto the polishing belt 4 will continue to be transported with the polishing belt 4 until it is discharged from the output end of the polishing belt 4. The user only needs to place an external collection structure below the output end of the polishing belt 4 to achieve automatic collection of debris.

[0028] The top ends of the four guide rods 6 are connected to a support plate 14. A cylinder 15 is fixedly connected to the upper surface of the support plate 14. A piston rod 16 is installed on the output end of the cylinder 15. The bottom end of the piston rod 16 moves through the support plate 14 and is fixed to the upper surface of the movable plate 7. It is used to drive the piston rod 16 to extend and retract through the cylinder 15 to adjust the position of the movable plate 7.

[0029] It should be noted that, in use, this new type of polishing device for processing automotive brake discs involves starting the cylinder 15 to drive the piston rod 16 to retract, which in turn drives the movable plate 7 to move upward to a suitable height. Then, the brake disc to be polished is placed on the polishing belt 4 below the movable plate 7. The cylinder 15 is then started again to drive the piston rod 16 to extend, which, together with the stop block 11 and pressure block 12 connected to the bottom of the slide rod 9, limits and presses the brake disc against the upper surface of the polishing belt 4. At this time, the motor 5 can be started, which, together with the transmission shaft 3, drives the polishing belt 4 to rotate at high speed, polishing the side of the brake disc that is in contact with the polishing belt 4. Because the stop block 11 is provided with a protective cover 13 on its periphery, the top of which is fixed to the lower surface of the movable plate 7, and one end of the protective cover 13 is sealed, the polishing debris generated will splash towards the sealed end of the protective cover 13 due to inertia caused by the rotation direction of the polishing belt 4. The splashed debris will fall back onto the polishing belt 4 due to the obstruction of the protective cover 13, thus preventing debris from splashing and easily polluting the working environment and affecting the health of the workers.

[0030] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
