Description

Technical Field

[0001] The invention relates to the field of brake disc cleaning devices, in particular to a brake disc surface cleaning device. Background Art

[0002] Brake discs are important parts in the automobile braking system. Brake discs are usually disc-shaped and can be divided into carbon fiber brake discs, metal brake discs, etc. according to different raw materials. Metal brake discs are usually made by casting. Among the casting processes, sand casting has low manufacturing cost and simple process, so it is the most widely used. Brake discs cast by sand casting need to be cleaned after casting to remove impurities such as gravel and metal chips remaining on the surface.

[0003] Related technologies can refer to the Chinese patent application with publication number CN118635170A, which discloses a surface cleaning device for automobile parts, including a placement base plate and a water tank and a processing manipulator detachably connected to the placement base plate, a pump detachably connected to the top surface of the water tank, a second bracket fixedly connected to the placement base plate and located on one side of the water tank, the second bracket is fixedly connected to the placement base plate through the installation base plate and the placement base plate, the top surface of the second bracket is fixedly connected to a connecting support, the top surface of the connecting support is fixedly connected to a first clamping frame, the first clamping frame is detachably connected to a telescopic rod and a clamping hydraulic cylinder on one side away from the connecting support, and the output end of the telescopic rod is fixedly connected to the second clamping frame. When the device is actually used, the upper guide bar and the lower guide bar can scrape the dust on the brake disc body, which can prevent the dust from adhering to the brake disc body for the second time, and can achieve efficient cleaning of the dust on the brake disc body.

[0004] Regarding the above-mentioned related technologies, the surface of the brake disc is usually provided with some uneven through holes and groove structures for weight reduction and heat dissipation. The interior of such hole and groove structures is more likely to retain stains or gravel debris, and the upper and lower guide strips are mainly used to clean the outer surface of the brake disc, and it is difficult to effectively clean the inner wall of the hole and groove of the brake disc. In the prior art, when cleaning the brake disc, in order to clean the inner wall of its hole and groove structure, the brake disc is usually flushed with high-speed airflow or cleaning liquid. However, for brake discs cast with molding sand, during the brake disc molding process, if the metal oxides formed by the chemical reaction of the metal liquid react with the molding sand, iron slag with strong adhesion will be formed. For such sticky sand, it is difficult to effectively clean it simply by airflow impact or cleaning with cleaning liquid, resulting in poor cleaning effect on the brake disc. Summary of the invention

[0038] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0039] The embodiment of the present application discloses a brake disc surface cleaning device.

[0040] Example:

[0041] Reference Figure 1 and Figure 2A brake disc surface cleaning device comprises a feeding conveyor belt 1, a cleaning box 3 and a discharging conveyor belt 2 in sequence. The cleaning box 3 is hollow, and the feeding conveyor belt 1 drives uncleaned brake discs to be transported to the cleaning box 3 when working. Two receiving trays 4 are arranged in the cleaning box 3, and the two receiving trays 4 are arranged along the length direction of the cleaning box 3.

[0042] Reference Figure 2 and Figure 3 A plurality of transport manipulators 31 are arranged in the cleaning box 3. The transport manipulators 31 are movable along the length direction and the height direction of the cleaning box 3. The transport manipulators 31 include a clamping jaw 311 cylinder and two clamping jaws 311. When the brake disc approaches the cleaning box 3 along the feeding conveyor belt 1, the clamping jaw 311 cylinder clamps the outer edge of the brake disc through the clamping jaws 311, and transports the brake disc from the feeding conveyor belt 1 to the support tray 4.

[0043] Reference Figure 2 and Figure 3 The support tray 4 includes a clamping plate 41 and a limiting plate 42. The clamping plate 41 is horizontally arranged and fixedly connected to the cleaning box 3. The upper end of the clamping plate 41 is slidably connected to two clamping plates 411 in a transverse direction. The cleaning box 3 is equipped with a clamping cylinder for pushing the clamping plate 411 toward or away from the axis of the clamping plate 41. The clamping plate 411 is provided with a rotating member 412. The rotating member 412 includes a rotating wheel and a motor. The rotating wheel is rotatably connected to one side of the clamping plate 411 close to the axis of the clamping plate 41. The motor is installed above the clamping plate 411 to drive the rotating wheel to rotate.

[0044] Reference Figure 2 and Figure 3 The handling manipulator 31 places the brake disc on top of the clamping disc 41, and the clamping disc 41 supports the brake disc. The clamping cylinder drives the clamping plate 411 close to the brake disc, and the clamping plate 411 drives the rotating wheel to contact the outer edge of the brake disc. When the motor drives the rotating wheel to rotate, the rotating wheel drives the brake disc to rotate around its own axis. At the same time, all the rotating wheels cooperate to clamp the brake disc, so that the brake disc and the clamping disc 41 are coaxial.

[0045] Reference Figure 2 and Figure 3 The limit plate 42 is located at the lower end of the clamping plate 41 and is coaxial with the clamping plate 41. A support rod is fixedly connected to the lower end of the limit plate 42. A support plate corresponding to the support rod is fixedly arranged in the cleaning box 3. The support rod passes through the support plate and is slidably connected to the support plate. A thrust spring is arranged between the limit plate 42 and the support plate. One end of the thrust spring is fixedly connected to the limit plate 42 and the other end is fixedly connected to the support plate. The thrust spring is in a compressed state and pushes the limit plate 42 to contact the clamping plate 41.

[0046] Reference Figure 2 and Figure 3, the brake disc is provided with multiple groups of through holes, and the multiple groups of through holes are evenly arranged along the circumference of the brake disc. The limiting disc 42 is vertically slidably connected with multiple positioning rods 421, and the positioning rods 421 correspond to the positions of the through holes. An elastic member 422 is provided between the positioning rod 421 and the limiting disc 42. The elastic member 422 is a spring, one end of the spring is fixedly connected to the positioning rod 421, and the other end is fixedly connected to the limiting disc 42. When the spring is in a natural state, it pushes the positioning rod 421 to approach the clamping disc 41. The clamping disc 41 is vertically opened with an avoidance groove 413. When the limiting disc 42 contacts the clamping disc 41, the positioning rod 421 passes through the avoidance groove 413 and extends to the top of the clamping disc 41.

[0047] Reference Figure 2 and Figure 3 When the brake disc is placed on the clamping disc 41, if the through hole is not directly opposite to the corresponding positioning rod 421, the brake disc is rotated by the rotating member 412 until the positioning rod 421 enters the corresponding through hole. At this time, the positioning rod 421 positions the brake disc.

[0048] Reference Figure 2 and Figure 4 A through hole cleaning disk 5 is also provided in the cleaning box 3. The through hole cleaning disk 5 is located just above the clamping disk 41 near the feeding conveyor belt 1, and the through hole cleaning disk 5 is coaxial with the clamping disk 41. A lifting platform 32 is provided in the cleaning box 3 for vertical reciprocating movement. The through hole cleaning disk 5 is arranged at the lower end of the lifting platform 32 and moves with the lifting platform 32. The through hole cleaning disk 5 includes a positioning disk 54 and a plurality of rotating rings 52 connected to the circumferential direction of the positioning disk 54. The positioning disk 54 is fixedly connected to the lifting platform 32. The plurality of rotating rings 52 are coaxial with each other and are sequentially sleeved. The positioning disk 54 is provided with an adjusting rod 541 for driving the rotating ring 52 to rotate.

[0049] Reference Figure 5 and Figure 4 The lower end of the rotating ring 52 is coaxially fixed with a driving ring 523, and a worm wheel 524 is fixedly arranged on the outer circumference of the driving ring 523 along the circumferential direction. The adjusting rod 541 is a worm, which passes through the through hole cleaning disk 5 and meshes with the corresponding worm wheel 524. Under the support of the positioning disk 54, the worm drives the worm wheel 524 to rotate when the worm rotates, and then drives the corresponding rotating ring 52 to rotate through the driving ring 523.

[0050] Reference Figure 2 and Figure 4 The rotating ring 52 is connected with a moving block 521 in a sliding manner along the diameter direction, and is provided with a positioning member 522 for positioning the positioning block. The positioning member 522 is a screw, which passes through the moving block 521 and is threadedly connected to the rotating ring 52. The rotating ring 52 positions the moving block 521 through the screw, so that the rotating ring 52 drives the moving block 521 to move when the rotating ring 52 rotates. Figure 2) is also provided with a plurality of cleaning rods 51, and the number of the cleaning rods 51 is the same as the number of the same group of through holes.

[0051] Reference Figure 2 and Figure 4 The cleaning rod 51 includes a round rod 511 and a straight plate 512. The round rod 511 is arranged parallel to the axis of the positioning plate 54. The round rod 511 corresponds to the moving block 521 one by one. The round rod 511 passes through the moving block 521 and is rotatably connected with the moving block 521. When the moving block 521 moves, the corresponding round rod 511 is driven to move. By adjusting the position of the swivel 52 and the moving block 521, the position of the cleaning rod 51 can be easily changed. In the initial state, the position of the cleaning rod 51 corresponds to the position of the through hole on the brake disc.

[0052] Reference Figure 4 and Figure 5 The straight plate 512 is parallel to the round rod 511, and the straight rod is fixedly connected to the outer circle of the round rod 511. When the round rod 511 moves, the straight rod is driven to move. The positioning plate 54 is provided with a driving member, which includes a driving motor 531, a driving wheel group 532 and a plurality of driven wheel groups 533. The driving motor 531 is installed at the upper end of the positioning plate 54, and the driving wheel group 532 is located between the driving motor 531 and the round rod 511 close to the driving motor 531. When the driving motor 531 is working, the driving wheel group 532 drives the corresponding round rod 511 to rotate.

[0053] Reference Figure 4 and Figure 5 The driven wheel set 533 is located between two adjacent round rods 511. When any round rod 511 rotates, the other round rods 511 are driven to rotate through the driven wheel set 533. Both the driving wheel set 532 and the driven wheel set 533 are belt drive structures. The rotating ring 52 is provided with a tensioning wheel 525. When the position of the cleaning rod 1 51 is adjusted through the rotating ring 52 and the moving block 521, the tensioning wheel 525 is used to keep the belts in all the driven wheel sets 533 in a tensioned state.

[0054] Reference Figure 2 and Figure 4 The lifting platform 32 is provided with a rotating member 33 for driving the through-hole cleaning disk 5 to rotate. In the initial state, when the brake disc is in the positioning state, the round rod 511 is coaxial with the corresponding through-hole, and the through-hole cleaning disk 5 is driven close to the brake disc by the lifting platform 32, so that the round rod 511 drives the straight plate 512 close to the corresponding through-hole. A push rod 321 is fixed at the lower end of the lifting platform 32, and a baffle 423 corresponding to the push rod 321 is fixed on the limit plate 42 directly below the through-hole cleaning disk 5. When the lifting platform 32 drives the through-hole cleaning disk 5 to descend, the push rod 321 first contacts the baffle 423, and then drives the limit plate 42 away from the clamping disk 41 through the baffle 423. At this time, the positioning rod 421 moves out of the through-hole, thereby avoiding the cleaning rod 51.

[0055] Reference Figure 2 and Figure 4 After the round rod 511 drives the straight plate 512 to enter the corresponding through hole, the driving motor 531 drives all the round rods 511 to rotate, so that the round rods 511 clean the inner wall of the through hole through the straight plate 512. After completing the cleaning of a group of through holes, the through hole cleaning disc 5 is driven to rotate by the rotating member 33, thereby realizing the cleaning of the inner wall of the remaining through holes of the brake disc.
