Description

Technical Field

[0001] The present application relates to the technical field of brake disc production, and in particular to a brake disc cleaning and spraying line. Background Art

[0002] Brake rotor, also known as brake disc, is an important part of the braking system for cars, motorcycles and other vehicles. It is a disc-shaped metal part, usually made of cast iron, steel or composite materials.

[0003] Cleaning, drying and spraying are key process links in the brake disc production process. At present, although there are a variety of equipment for cleaning and spraying brake discs, these equipment are often scattered, resulting in cumbersome and inefficient processing. Therefore, it is necessary to integrate the cleaning, drying and spraying processes into one production line to improve the processing efficiency.

[0004] During the cleaning and spraying process, multiple brake discs are laid out on the assembly line. There are multiple rows of brake discs arranged along the conveying direction, and each row of brake discs is spaced perpendicular to the conveying direction. When the conveying of the conveyor line is inconsistent or the brake discs are not kept at a certain distance when they are placed in, many brake discs are easy to collide with each other, which will make some parts of the brake discs unable to be cleaned, dried and sprayed, thereby reducing the cleaning and spraying effect of the brakes. In addition, the collision of brake discs with each other can easily cause damage to the brake discs, which will lead to a decrease in the quality of the brake discs. Summary of the invention

[0005] In order to improve the quality of brake discs, the present application provides a brake disc cleaning and spraying line.

[0006] The brake disc cleaning and spraying line provided in this application adopts the following technical solutions: The brake disc cleaning and spraying line includes a frame, a conveying line, a cleaning device, a drying device and a spraying device. The frame is also provided with an arranging device for arranging the brake discs neatly. The arranging device is provided in plurality and is located in front of the cleaning device and between the drying device and the spraying device. The arranging device includes: A rotating shaft, which is rotatably arranged on the frame and whose axis is perpendicular to the conveying direction of the conveying line; A plurality of push rings are arranged on the rotating shaft at intervals along the axis direction of the rotating shaft and are used to push adjacent brake discs in the same row away from each other and keep a certain space between two adjacent brake discs; A push plate is slidably disposed on the frame and is used to push two adjacent batches of brake discs away from each other and to keep a certain space between two adjacent rows of brake discs; The driving mechanism is used to drive the rotating shaft to rotate and simultaneously drive the pushing plate to move.

[0007] By adopting the above technical solution, multiple brake discs are placed on the conveyor line for transportation, and the driving mechanism drives the rotating shaft to rotate, and the rotating shaft turns to drive multiple pushing rings to rotate. The multiple pushing rings are used to push multiple brake discs in the same row away from each other, so that a certain space is maintained between two adjacent brake discs. At the same time, the driving mechanism drives the pushing plate to move vertically. When the two rows of brake discs move so that the pushing plate is located between the two rows of brake discs, the pushing plate moves down and is inserted between the two rows of brake discs. The brake disc located in front of the pushing plate moves forward normally, and the pushing plate blocks the movement of the next batch of brake discs. Then the pushing plate moves up, so that a certain space can be maintained between the multiple brake discs. This space is convenient for subsequent cleaning and drying, and then the dried brake discs continue to be arranged through the arranging device, so as to facilitate subsequent spraying. Therefore, the cleaning, drying and spraying effects of the brake discs are greatly improved, and the probability of the brake discs colliding with each other is reduced, thereby improving the quality of the brake discs.

[0008] Optionally, the driving mechanism includes: A driving member, used for driving the rotating shaft to rotate; A driving disc, rotatably disposed on the frame and connected to the rotating shaft through a linkage assembly; A drive shaft, eccentrically disposed on the drive disc; The spring has two ends respectively connected with the driving shaft and the pushing plate.

[0009] By adopting the above technical solution, the driving member drives the rotating shaft to rotate, and the rotation of the rotating shaft drives the driving disk to rotate through the linkage assembly. The rotation of the driving disk drives the driving shaft to rotate around the axis of the driving disk, and the driving shaft rotates to realize the up and down movement of the pushing plate through the spring, and when the pushing plate is not between the two rows of brake discs when moving down, the pushing plate is pressed against the brake disc under the action of gravity, and at this time, the spring tension can overcome a part of the gravity of the pushing plate, reducing the damage of the pushing plate to the brake disc, and also reducing the resistance generated when the brake disc moves, so that when the brake disc moves forward and the pushing plate is located between the two rows of brake discs, the pushing plate moves down under the action of gravity, thereby blocking the movement of the brake discs in the rear row, and then the driving plate continues to move up under the tension of the spring, and the rear batch of brake discs continues to move, so as to maintain a certain space between the two adjacent batches of brake discs while also reducing the damage to the brake discs.

[0010] Optionally, the linkage component includes: A main gear, disposed on the rotating shaft; The secondary gear is arranged on the driving plate and meshes with the primary gear.

[0011] By adopting the above technical solution, the rotating shaft rotates to drive the main gear to rotate, and the main gear rotates to drive the sub-gear and the driving plate to rotate.

[0012] Optionally, a guide angle is provided on the lower surface of the push plate to facilitate insertion between two adjacent rows of brake discs.

[0013] By adopting the above technical solution, when the guide angle is inserted between two rows of brake discs, the guide angle pushes the front row of brake discs forward and the rear row of brake discs backward until the push plate extends between the two rows of brake discs, thereby being able to more quickly maintain a certain space between two adjacent batches of brake discs.

[0014] Optionally, the push ring is slidably sleeved on the rotating shaft and threadedly connected to a positioning screw that presses against the rotating shaft for positioning.

[0015] By adopting the above technical solution, the push ring can be replaced and the arrangement of brake discs of different sizes and numbers can be adapted, thereby improving the adaptability of the structure.

[0016] Optionally, a plurality of cleaning devices are arranged at intervals, and a scrubbing mechanism is arranged on the frame and between the plurality of cleaning devices, and the scrubbing mechanism comprises: Two moving blocks are slidably arranged on the frame along the axis of the rotating shaft and are located at the upper and lower sides of the brake disc; Two brushing rollers are rotatably arranged on the frame and their axes are parallel to the axis of the rotating shaft. The two brushing rollers are located on the upper and lower sides of the brake disc and cooperate to brush the brake disc; A pushing assembly, disposed on the frame and used to push the two moving blocks toward or away from each other; The rotating assembly is arranged on the frame and is used for driving the two brush rollers to rotate.

[0017] By adopting the above technical solution, impurities easily adhere to the brake disc, and it is difficult to remove the impurities by spraying alone, which reduces the spraying effect. If the spraying time is extended, the spraying effect can be improved, but the spraying efficiency is reduced, so the two cannot be achieved at the same time; The rotating component drives the two brush rollers to rotate, and the pushing component drives the two moving blocks to move closer to or away from each other, thereby realizing that the two brush rollers rotate and move closer to or away from each other at the same time, and the two brush rollers brush the upper and lower surfaces of the brake disc during movement, and the cleaning device first cleans the brake disc, and then it is brushed by the brush rollers, and then the brake disc is sprayed and cleaned again, thereby greatly reducing the probability of impurities adhering to the brake disc and improving the cleaning effect of the brake disc, and the two brush rollers move closer to or away from each other, so that the brushing thrusts on the upper and lower brake discs offset each other, reducing the probability of the brush rollers pushing the brake disc to move and colliding and interfering with subsequent drying, thereby further improving the quality of the brake disc.

[0018] Optionally, the pushing component includes: A fixed block is arranged on the frame and is provided with a rotating groove, the rotating groove is provided with an annular moving groove, the brush roller is rotatably arranged on the rotating groove and is provided with a moving column slidably arranged on the moving groove, the rotation of the brush roller drives the moving column to move in the moving groove and drives the brush roller and the moving column to reciprocate; A swing rod is rotatably arranged on the frame and has two ends extending to two moving blocks and is provided with waist-shaped swing holes; Two swing columns are respectively arranged on the two moving blocks and are slidably installed on the two swing holes.

[0019] By adopting the above technical solution, the rotation of the brush roller drives the moving column to rotate, and the moving column moves in the moving groove to drive the brush roller and the moving block to move. At the same time, the movement of one moving block drives the other moving block to move in the opposite direction through the swing rod, so that the two brush rollers rotate and move closer to or away from each other.

[0020] Optionally, the rotating assembly includes: Two rotating gears are respectively arranged on the two brush rollers and mesh with each other; The rotating member is arranged on the frame and is slidingly connected with one of the brushing rollers through a sliding assembly and drives the brushing roller to rotate.

[0021] By adopting the above technical solution, the driving member drives a brush roller to rotate through the sliding assembly, and the rotation of the brush roller drives another brush roller to rotate through two rotating gears, thereby realizing the rotation of the two brush rollers to brush the brake disc; at the same time, the sliding assembly facilitates the movement of the brush roller, so that the driving member does not need to move but the brush roller is convenient to move.

[0022] Optionally, the sliding assembly includes: A sliding sleeve is used to connect with the rotating member and is arranged on the brushing roller; The sliding block is arranged on the sliding sleeve and is slidingly mounted on the brush roller so as to make the sliding sleeve and the brush roller rotate simultaneously.

[0023] By adopting the above technical solution, the driving member drives the sliding sleeve to rotate, the sliding sleeve rotates to drive the sliding block and the brush roller to rotate, and the brush roller moves to drive the sliding block to move on the sliding sleeve, so that the driving member drives the brush roller to rotate without moving.

[0024] Optionally, a filter frame for filtering is placed on the frame and below the two brush rollers.

[0025] By adopting the above technical solution, the filter frame is used to filter impurities, thereby improving the cleaning effect of the brake disc.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: A plurality of pushing rings are used to push a plurality of brake discs in the same row away from each other, so that a certain space is maintained between two adjacent brake discs. At the same time, a driving mechanism drives a pushing plate to move vertically. When the two rows of brake discs move so that the pushing plate is located between the two rows of brake discs, the pushing plate moves downward and is inserted between the two rows of brake discs, so that a certain space is maintained between the plurality of brake discs. This space is convenient for subsequent cleaning and drying. The dried brake discs are then continuously arranged through an arranging device, so as to facilitate subsequent spraying. Therefore, the cleaning, drying and spraying effects of the brake discs are greatly improved, the probability of the brake discs colliding with each other is reduced, and the quality of the brake discs is improved.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-4 This application is described in further detail.

[0030] The embodiments of the present application disclose a brake disc cleaning and spraying line.

[0031] Reference Figure 1The brake disc cleaning and spraying line includes a frame, a conveyor line 11, a cleaning device 2, a drying device 13 and a spraying device 14. The conveyor line 11 is used to convey the brake discs. The cleaning device 2, the drying device 13 and the spraying device 14 are arranged at intervals along the conveying direction of the conveyor line 11 and are respectively used to clean, dry and spray the brake discs. At the same time, two spraying devices 14 are arranged at intervals. The conveyor line 11 conveys the brake discs, which are cleaned and baked in turn and divided into two batches and then sprayed by two spraying devices 14. Arrangement devices 3 are arranged on the frame and located in front of the cleaning device 2 and between the drying device 13 and the spraying device 14. The arrangement device 3 is used to arrange multiple brake discs neatly and keep a certain space between two adjacent brake discs, so as to facilitate the cleaning, drying and spraying of the brake discs.

[0032] Reference Figure 1 and Figure 2 The cleaning device 2 includes a cleaning box 21, a cleaning pump and a spray pipe 22. The cleaning box 21 is located below the conveying line 11 and is filled with cleaning liquid. The cleaning pump is fixedly installed in the cleaning box 21. Two groups of spray pipes 22 are arranged at intervals along the conveying direction of the conveying line 11, and each group of spray pipes 22 is arranged at intervals along the conveying direction of the conveying line 11. The spray pipes 22 are all connected to the spray pump. At the same time, spray pipes 22 are arranged on both sides of the conveying line 11. The spray pipes 22 spray and clean the upper and lower surfaces of the brake disc at the same time. The drying device 13 adopts the existing hot air drying system, and the spraying device 14 also adopts the existing spraying system, which will not be repeated here.

[0033] The following explanation is given by taking the arrangement device 3 located in front of the cleaning device 2 as an example. The conveyor line 11 is formed by a plurality of rotating conveyor rollers 12. The conveyor rollers 12 are in a horizontal state and their axes are perpendicular to the conveying direction of the conveyor line 11. The arrangement device 3 includes a rotating shaft 31, a plurality of pushing rings 32, a pushing plate 33 and a driving mechanism 4. The rotating shaft 31 is rotatably mounted on the frame and is located above the conveyor line 11. The axes of the rotating shaft 31 and the conveyor rollers 12 are parallel, that is, the axis of the rotating shaft 31 is perpendicular to the conveying direction of the conveyor line 11.

[0034] Reference Figure 2 and Figure 3 The push ring 32 is coaxially slidably sleeved on the rotating shaft 31, and the push ring 32 is threadedly connected with a positioning screw that is pressed against the rotating shaft 31 to position the push ring 32. The push ring 32 is located between two adjacent brake discs. The rotating shaft 31 rotates to drive the multiple push rings 32 to rotate. The multiple push rings 32 push the multiple brake discs in the same row away from each other, so that a certain space is formed between the two adjacent brake discs.

[0035] The push plate 33 is vertically slidably installed on the frame, and the push plate 33 is located on the input side of the rotating shaft 31 close to the brake disc. At the same time, the push plate 33 is located above the conveyor line 11, and the length direction of the push plate 33 is parallel to the axial direction of the conveyor roller 12; the driving mechanism 4 is used to drive the rotating shaft 31 to rotate and the push plate 33 to move vertically. The driving mechanism 4 includes a driving member 41, a driving disk 42, a driving shaft 43 and a spring 44. The driving member 41 is a servo motor. The driving member 41 is fixedly installed on the frame and the output shaft is connected to the rotating shaft 31 to drive the rotating shaft 31 to rotate.

[0036] The driving disk 42 is rotatably installed on the frame and is located above the pushing plate 33. There are two driving disks 42 and they are located at both ends of the pushing plate 33. At the same time, the rotation direction axis of the driving disk 42 is parallel to the axis direction of the conveying roller 12. There are two driving shafts 43 and they are eccentrically arranged on the side walls of the two driving disks 42. The axis of the driving shaft 43 is parallel to the rotation direction axis of the driving disk 42. There are two springs 44 and they are arranged one by one with the two driving shafts 43. Fixed rings 45 are fixedly installed on the upper surfaces of both ends of the pushing plate 33, and both ends of the spring 44 are hooked on the driving shaft 43 and the fixed ring 45.

[0037] The driving disc 42 is connected to the rotating shaft 31 through the linkage assembly 5, and the linkage assembly 5 includes a main gear 51 and a sub gear 52. The main gear 51 is keyed to the rotating shaft 31, and the sub gear 52 is keyed to the driving disc 42 and meshes with the main gear 51. The driving member 41 drives the rotating shaft 31 to rotate, and the rotation of the rotating shaft 31 drives the driving disc 42 to rotate through the main gear 51 and the sub gear 52. The rotation of the driving disc 42 drives the driving shaft 43 to rotate around the axis of the driving disc 42, and the rotation of the driving shaft 43 pulls the push plate 33 up and down through the spring 44.

[0038] The push plate 33 moves according to the set time, which is determined by the moving speed of the brake discs. When the two rows of brake discs move and the push plate 33 moves between the two rows of brake discs, the push plate 33 moves down and extends between the two rows of brake discs, so that a certain space is maintained between the two rows of brake discs, and then the push plate 33 moves up to above the brake discs. Therefore, the push plate 33 and the push ring 32 cooperate to maintain a certain space between two adjacent brake discs; a guide angle 34 is provided on the lower surface of the push plate 33 for easy insertion between the two rows of brake discs.

[0039] Reference Figure 2 and Figure 4A scrubbing mechanism 6 for scrubbing the upper and lower surfaces of the brake disc is arranged on the frame and between the two groups of spray pipes 22. The scrubbing mechanism 6 includes two moving blocks 61, two scrubbing rollers 62, a pushing assembly 63 and a rotating assembly 7. The two moving blocks 61 are slidably arranged on the frame along the axis direction of the conveying roller 12, and the two moving blocks 61 are located on the upper and lower sides of the brake disc, and the sliding directions of the two moving blocks 61 are opposite; one ends of the two scrubbing rollers 62 are rotatably installed on the two moving blocks 61, and the axes of the two scrubbing rollers 62 are parallel to the axis of the conveying roller 12 and cooperate to scrub the upper and lower surfaces of the brake disc.

[0040] The pushing assembly 63 is arranged on the frame and is used to push the two moving blocks 61 towards or away from each other. The pushing assembly 63 includes a fixed block 64, a swing rod 65 and two swing columns 66. The fixed block 64 is fixedly installed on the frame and is provided with a rotating groove 67 which coincides with the axis of the brush roller 62. The brush roller 62 located above the brake disc is rotatably installed on the rotating groove 67; the rotating groove 67 is coaxially provided with an annular and inclined moving groove 68, and the brush roller 62 is fixedly installed with a moving column 69 which is slidably installed on the moving groove 68. The rotation of the brush roller 62 drives the moving column 69 to move on the moving groove 68. The brush roller 62 rotates and realizes the reciprocating movement of the brush roller 62 with the cooperation of the moving groove 68 and the moving column 69.

[0041] The swing rod 65 is rotatably installed on the frame and its two ends extend to the two moving blocks 61 and a swing hole 651 is opened along the length direction of the swing rod 65. Two swing columns 66 are fixedly installed on the two moving blocks 61, and the two swing columns 66 are slidably installed on the two swing holes 651 respectively; the brush roller 62 connected to the fixed block 64 reciprocates and drives the other brush roller 62 to reciprocate through the swing rod 65. The two brush rollers 62 rotate and reciprocate at the same time and make the moving directions of the two opposite.

[0042] The rotating assembly 7 is arranged on the frame and is used to drive the two brush rollers 62 to rotate. The rotating assembly 7 includes two rotating gears 71 and a rotating member 72. The two rotating gears 71 are respectively keyed to one end of the two brush rollers 62 close to the fixed block 64 and mesh with each other; the rotating member 72 is a rotating motor, the rotating member 72 is fixedly installed on the frame, and the output shaft of the rotating member 72 and the axis of the brush roller 62 located under the brake disc coincide with each other. At the same time, the output shaft of the rotating member 72 is slidingly connected to the brush roller 62 through the sliding assembly 8 and is used to drive the brush roller 62 to rotate; a filter frame for filtration is fixedly installed on the frame and below the two brush rollers 62.

[0043] The sliding assembly 8 includes a sliding sleeve 81 and a sliding block 82. The sliding sleeve 81 is coaxially fixedly installed on the output shaft of the rotating member 72, and the brush roller 62 is rotatably sleeved in the sliding sleeve 81, and the brush roller 62 is slidingly connected to the sliding sleeve 81; the sliding block 82 is fixedly installed on the sliding sleeve 81, and the sliding block 82 is slidably installed on the brush roller 62, so that the rotating member 72 drives the sliding sleeve 81 to rotate, and the sliding sleeve 81 drives the sliding block 82 and the brush roller 62 to rotate, and at the same time, the rotation of the brush roller 62 drives the other brush roller 62 to rotate through the two rotating gears 71, and when the brush roller 62 moves, the sliding block 82 cooperates with the sliding sleeve 81 to avoid the position.

[0044] The working principle of the embodiment of the present application is as follows: The conveyor line 11 conveys the brake disc to move, and the driving member 41 drives the rotating shaft 31 and multiple pushing rings 32 to rotate. The multiple pushing rings 32 push two adjacent brake discs away from each other, and the rotating shaft 31 rotates to drive the pushing plate 33 to move up and down. When the pushing plate 33 is located between two rows of brake discs, the pushing plate 33 moves down between the two rows of brake discs to form a certain space between the two rows of brake discs, and then the pushing plate 33 moves up to above the brake disc. Therefore, the pushing plate 33 and the pushing ring 32 cooperate to form a certain space between two adjacent brake discs, so that multiple brake discs are arranged neatly, so as to facilitate subsequent cleaning, drying and spraying.

[0045] The spray pipe 22 sprays the upper and lower surfaces of multiple neatly arranged brake discs, and then the brake discs are moved to the brush rollers 62. The rotating member 72 drives the two brush rollers 62 to rotate and move back and forth. The two brush rollers 62 work together to brush the brake discs, and then the brake discs continue to move to the spray pipe 22 for spraying. Then the brake discs are dried and sprayed in turn through the drying device 13 and the spraying device 14, thereby improving the quality of the brake discs.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
