Description

Technical Field

[0001] The invention belongs to the technical field of brake disc painting, in particular to a brake disc painting device. Background Art

[0002] The brake disc, also known as the brake disc or brake disc, is a key component in the disc brake system. When the driver steps on the brake pedal, the brake caliper clamps the brake disc and generates braking force through friction to stop the wheels from rotating, thereby slowing down or stopping the vehicle. During the production process, the non-braking surface of the brake disc is usually painted to enhance its corrosion resistance, rust resistance and aesthetic appearance.

[0003] The patent with the announcement number CN214515466U discloses a brake disc painting device, including a conveyor line for conveying brake discs, a paint spraying partition is arranged above the conveyor line, and a paint spraying mechanism is arranged on the paint spraying partition. The patent sets components such as a conveyor line, a paint spraying partition and a paint spraying mechanism. When the brake disc is transported to the limit column, the ejector column can be used to lift the brake disc and pass it through the inlet and outlet hole, so that the brake disc enters the paint spraying mechanism for painting. When the painting is completed, the limit column drops, and the ejector column puts the brake disc back on the conveyor line. The conveyor line transports the painted brake disc to the next processing link. The entire painting process is mechanized, which greatly improves the efficiency and quality of painting and reduces labor.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] Although the brake disc can be covered with a protective cover and then painted to reduce the paint spray from scattering into the surrounding environment, usually, only the non-braking surface of the brake disc needs to be painted, because the braking surface of the brake disc needs to be in close contact with the brake pad and generate sufficient friction to achieve the braking effect. If the braking surface is covered with paint, its surface roughness and hardness may be changed, thereby affecting the friction coefficient with the brake pad. In the above technical solution, when painting the non-braking surface of the brake disc, the paint may splash or flow into the braking surface along the edge of the brake disc, thereby affecting the subsequent use of the brake disc.

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. The paint spraying equipment for brake discs described in the present invention utilizes a positioning mechanism to place the brake disc to be painted on the upper end surface of the positioning disc, and multiple positioning blocks pass through the through hole in the middle of the brake disc, driving the multiple positioning blocks to slide radially at the same time until the positioning blocks fit with the inner wall of the through hole in the middle of the brake disc, so that the brake disc can be fixed, thereby positioning brake discs of different sizes, thereby ensuring the stability of the brake disc during the painting process.

[0023] 2. The brake disc painting equipment described in the present invention utilizes an adjustable wrapping mechanism and a traction-type unwinding mechanism. When the brake disc is fixed above the positioning disc, the non-braking surface of the brake disc faces upward, and the size and height of the elastic cloth are adjusted to make the edge of the through hole in the middle of the elastic cloth fit with the edge of the non-braking surface of the brake disc. During the painting process, splashing and flowing paint will be blocked by the elastic cloth, thereby avoiding the situation where the paint splashes or flows into the braking surface along the edge of the brake disc, thereby ensuring the subsequent use effect of the brake disc. Moreover, after the elastic cloth adheres to a certain amount of paint, the elastic cloth adhered to the paint is removed from the tray, and the elastic cloth roller is driven to rotate so that the elastic cloth roll can be unrolled. When the end of the elastic cloth roll is separated from the end of the support platform, the pressure roller presses the edge of the elastic cloth roll against the lower surface of the pressing plate until four fixed The positioning post is aligned with the circular through hole on the elastic cloth roll, the elastic cloth roller stops rotating, driving the lifting ring to rise, the positioning post passes through the circular through hole, driving the blade plate to descend, and using the blade at its bottom to cut the elastic cloth roll. At this time, an independent square elastic cloth is sleeved on the positioning post, and the positioning plates on both sides are driven to move at the same time and fit with the circular through hole of the elastic cloth to ensure the stability of the elastic cloth sleeved on the positioning post. Then the lifting ring drives the elastic cloth to descend for subsequent paint blocking work. By repeating the above operation, the elastic cloth with too much paint can be automatically replaced multiple times, thereby avoiding the situation where too much paint adheres to the elastic cloth, the paint leaks from the upper surface of the elastic cloth to the bottom thereof, resulting in paint adhering to the braking surface of the brake disc that is subsequently painted, thereby improving the recycling effect of the elastic cloth.

[0054] Specifically, when the existing brake disc painting device is in use, although the brake disc can be covered with a protective cover and then painted to reduce the paint spray from scattering into the surrounding environment, usually, the brake disc only needs to be painted on the non-braking surface, because the braking surface of the brake disc needs to be in close contact with the brake pad and generate sufficient friction to achieve the braking effect. If the braking surface is covered with paint, the roughness and hardness of its surface may be changed, thereby affecting the friction coefficient with the brake pad. In the prior art, when the non-braking surface of the brake disc is painted, the paint may splash or flow into the braking surface along the edge of the brake disc, thereby affecting the subsequent use effect of the brake disc.

[0055] Therefore, in order to avoid the above problems, when the present embodiment is in use, after the brake disc is fixed above the positioning disc 14, the non-braking surface of the brake disc faces upward, and then, according to the thickness and diameter of the brake disc, the motor nine 47 is used to drive the threaded rod one 18 to rotate, so that the lifting ring 19 moves up and down, so that the edge of the through hole in the middle of the elastic cloth 7 is aligned with the edge of the non-braking surface of the brake disc, and then the motor three 21 is used to drive the threaded rod two 22 to rotate, so that the adjusting ring 24 can be moved downward, and the multiple connecting rods one 25 are used to drive the multiple adjusting rods 20 to slide radially on the lifting ring 19 at the same time, so that the elastic cloth 7 can be deformed by controlling the positions of the four corners of the elastic cloth 7, and the size of the through hole in the middle of the elastic cloth 7 can also be changed by stretching the elastic cloth 7 until the edge of the through hole in the middle of the elastic cloth 7 can be aligned with the non-braking surface of the brake disc. The edges are fitted. At this time, the non-braking surface of the brake disc is surrounded by the elastic cloth 7. At the same time, the motor 2 12 is used to drive the threaded rod 6 54 to rotate, and the motor 11 53 drives the threaded rod 7 52 to rotate, so that the longitudinal and lateral positions of the paint spray nozzle 13 can be changed, so that the paint spray nozzle 13 is aligned with the position of the brake disc to be painted, and then the paint in the paint box 2 is extracted by the pump body 3, and sprayed from the paint spray nozzle 13 to the surface of the brake disc after passing through the hose 4. At the same time, the motor 4 28 can be used to drive the positioning plate 14 to rotate, so that the brake disc rotates to improve the uniformity of the paint spraying. Since the non-braking surface of the brake disc is surrounded by the elastic cloth 7, the splashing and flowing paint will be blocked by the elastic cloth 7, thereby avoiding the situation where the paint splashes or flows into the braking surface of the brake disc along the edge of the brake disc, thereby ensuring the subsequent use effect of the brake disc;

[0056] After the elastic cloth 7 has been used for a period of time, as more paint adheres to the elastic cloth 7, the paint will leak from the upper surface of the elastic cloth 7 to the lower surface thereof, thereby causing paint to adhere to the braking surface of the brake disc that is subsequently painted, thereby causing trouble. Therefore, in order to avoid this situation, after the elastic cloth 7 has adhered to a certain amount of paint, the elastic cloth 7 is removed from the tray 46, and then the motor 6 is used to drive the elastic cloth roller 5 to rotate, so that the elastic cloth roll 56 can be unwound, and the end of the elastic cloth roll 56 passes through the gap between the limit rod 10 and the support platform 11. At the same time, the electric push rod 36 is used to drive the pressing plate 38 to descend, and the pressing plate 38 presses the end of the elastic cloth roll 56, and under the effect of the motor 6 33 driving the threaded rod 34 to rotate, the end of the elastic cloth roll 56 and the pressing plate 38 move synchronously, and the pressing plate 38 can have a traction effect on the end of the elastic cloth roll 56, thereby preventing the elastic cloth roll 56 from curling when moving on the support platform 11. When the end of the elastic cloth roll 56 is separated from the end of the support platform 11, the motor 7 40 drives the pressing roller 39 to rotate, pressing the edge of the end of the elastic cloth roll 56 tightly against The lower surface of the pressing plate 38 is moved until the four positioning posts 15 are aligned with the four circular through holes on the elastic cloth roll 56, the elastic cloth roll 5 stops rotating, and then the lifting ring 19 is driven to rise until the positioning posts 15 pass through the circular through holes, and then the motor 10 49 drives the threaded rod 50 to rotate, so that the blade plate 51 can be lowered to cut the elastic cloth roll 56 with the blade at the bottom. At this time, an independent square elastic cloth 7 is sleeved on the positioning posts 15, and the positioning plates 16 on both sides are driven to move at the same time to align with the circular through holes on the elastic cloth 7. The holes are fitted to ensure the stability of the elastic cloth 7 being sleeved on the positioning column 15, and then the pressing plate 38 and the pressing roller 39 loosen the elastic cloth 7 and reset it to the initial position. At this time, the lifting ring 19 can drive the elastic cloth 7 to descend to perform subsequent paint blocking work. By repeating the above operation, the elastic cloth 7 with too much paint can be automatically replaced multiple times, thereby avoiding the situation where the paint leaks from the upper surface of the elastic cloth 7 to the bottom thereof, resulting in the paint adhering to the braking surface of the brake disc to be subsequently painted, thereby improving the continuous use effect of the elastic cloth 7.

[0057] Working principle: the brake disc to be painted is placed on the upper end surface of the positioning disc 14, with the non-braking surface facing upwards, and multiple positioning blocks 29 pass through the through hole in the middle of the brake disc, and then the motor five 30 is used to drive the turntable 31 to rotate, so that the multiple connecting rods 2 32 can be rotated at the same time, and the multiple positioning blocks 29 can slide radially at the same time until the positioning blocks 29 are in contact with the inner wall of the through hole in the middle of the brake disc, so that the brake disc can be fixed, so that brake discs of different sizes can be positioned, thereby ensuring the stability of the brake disc during painting, and then according to the thickness and diameter of the brake disc, the motor nine 47 is used to drive the threaded rod one 18 to rotate, so that the lifting ring 19 moves up and down, so that the edge of the through hole in the middle of the elastic cloth 7 is aligned with the edge of the non-braking surface of the brake disc, and then the motor three 21 is used to drive the threaded rod two 22 to rotate, so that the adjusting ring 24 can move downward, and the multiple connecting rods one 25 are used to drive the multiple adjusting rods 20 to slide radially on the lifting ring 19 at the same time, so that the positions of the four corners of the elastic cloth 7 can be controlled to achieve the desired effect. The elastic cloth 7 is deformed, and the size of the through hole in the middle of the elastic cloth 7 can also be changed by stretching the elastic cloth 7, until the edge of the through hole in the middle of the elastic cloth 7 can fit with the edge of the non-braking surface of the brake disc. At this time, the non-braking surface of the brake disc is surrounded by the elastic cloth 7. At the same time, the motor 2 12 is used to drive the threaded rod 6 54 to rotate, and the motor 11 53 drives the threaded rod 7 52 to rotate, so that the longitudinal and lateral positions of the paint spray nozzle 13 can be changed, so that the paint spray nozzle 13 is aligned with the position of the brake disc to be painted, and then the paint in the paint box 2 is extracted by the pump body 3, and sprayed from the paint spray nozzle 13 to the surface of the brake disc after passing through the hose 4. At the same time, the motor 4 28 can be used to drive the positioning plate 14 to rotate, so that the brake disc rotates to improve the uniformity of the paint spraying. Since the non-braking surface of the brake disc is surrounded by the elastic cloth 7, the splashing and flowing paint will be blocked by the elastic cloth 7, thereby avoiding the situation where the paint splashes or flows into its braking surface along the edge of the brake disc, thereby ensuring the subsequent use effect of the brake disc;After the elastic cloth 7 has been used for a period of time, as more paint adheres to the elastic cloth 7, the paint will leak from the upper surface of the elastic cloth 7 to the lower surface thereof, thereby causing paint to adhere to the braking surface of the brake disc that is subsequently painted, thereby causing trouble. Therefore, in order to avoid this situation, after the elastic cloth 7 has adhered to a certain amount of paint, the elastic cloth 7 is removed from the tray 46, and then the motor 6 is used to drive the elastic cloth roller 5 to rotate, so that the elastic cloth roll 56 can be unwound, and the end of the elastic cloth roll 56 passes through the gap between the limit rod 10 and the support platform 11. At the same time, the electric push rod 36 is used to drive the pressing plate 38 to descend, and the pressing plate 38 presses the end of the elastic cloth roll 56, and under the effect of the motor 6 33 driving the threaded rod 34 to rotate, the end of the elastic cloth roll 56 and the pressing plate 38 move synchronously, and the pressing plate 38 can have a traction effect on the end of the elastic cloth roll 56, thereby preventing the elastic cloth roll 56 from curling when moving on the support platform 11. When the end of the elastic cloth roll 56 is separated from the end of the support platform 11, the motor 7 40 drives the pressing roller 39 to rotate, pressing the edge of the end of the elastic cloth roll 56 tightly against The lower surface of the pressing plate 38 is moved until the four positioning posts 15 are aligned with the four circular through holes on the elastic cloth roll 56, the elastic cloth roll 5 stops rotating, and then the lifting ring 19 is driven to rise until the positioning posts 15 pass through the circular through holes, and then the motor 10 49 drives the threaded rod 50 to rotate, so that the blade plate 51 can be lowered to cut the elastic cloth roll 56 with the blade at the bottom. At this time, an independent square elastic cloth 7 is sleeved on the positioning posts 15, and the positioning plates 16 on both sides are driven to move at the same time to align with the circular through holes on the elastic cloth 7. The holes are fitted to ensure the stability of the elastic cloth 7 sleeved on the positioning column 15, and then the pressing plate 38 and the pressing roller 39 loosen the elastic cloth 7 and reset it to the initial position. At this time, the lifting ring 19 can drive the elastic cloth 7 to descend to perform the subsequent paint blocking work. Repeating the above operation can realize multiple automatic replacements of the elastic cloth 7 with excessive paint adhered, thereby avoiding the situation where the paint leaks from the upper surface of the elastic cloth 7 to the bottom thereof, resulting in the paint adhering to the brake surface of the brake disc to be subsequently painted, thereby improving the continuous use effect of the elastic cloth 7. ;
