Description

Technical Field

[0001] This invention relates to the field of disc brake disc processing equipment technology, and specifically discloses a high-efficiency disc brake disc cleaning device. Background Technology

[0002] Disc brake discs, also known as brake discs, are the core safety component of a vehicle's braking system. During the manufacturing process of disc brake discs, various processing steps such as turning, drilling, heat treatment, and painting are required. These processes inevitably introduce various impurities into the surface of the disc brake disc. Especially during processes like quenching and tempering, oxide scale, sintered contaminants, and salt bath residues are formed, which are difficult to remove completely using conventional ultrasonic cleaning methods.

[0003] Patent application number 202411026127.0 discloses a high-efficiency cleaning device for brake discs before heat treatment. The device includes a cleaning tank with an installation wall on one side. A lower surface cleaning component, a side wall cleaning component, and an upper surface cleaning component are sequentially and horizontally slidably mounted on the installation wall along the direction from the upper conveyor belt to the lower conveyor belt. This invention discloses a cleaning device that, by setting up the lower surface cleaning component, side wall cleaning component, and upper surface cleaning component, divides the cleaning of a brake disc into three parts: the lower surface, the channel, and the upper surface. Through the cooperation of the three workstations, one of the three processes is completed alternately, achieving the purpose of high-efficiency separate cleaning. Although this cleaning device achieves the cleaning of the three parts of the same brake disc through the cooperation of the three workstations, it can still only process one brake disc at a time, thus limiting its cleaning efficiency. Furthermore, the actions of the robotic arm in grasping, transferring, and unloading materials greatly limit the overall cleaning efficiency of the device. Therefore, in view of the above-mentioned shortcomings of existing high-efficiency cleaning devices for brake discs before heat treatment, this application proposes a brand-new high-efficiency cleaning device for disc brake discs, which can perform brushing and ultrasonic cleaning on multiple disc brake discs at a time through assembly line operation, thereby effectively improving the cleaning efficiency of disc brake discs while ensuring the cleaning effect. Summary of the Invention

[0004] The purpose of this invention is to provide a high-efficiency disc brake disc cleaning device that enables continuous brushing and ultrasonic cleaning of multiple disc brake discs in a streamlined operation, thereby greatly improving cleaning efficiency and ensuring cleaning effect.

[0005] This invention is achieved through the following technical solution: A high-efficiency disc brake cleaning device includes a cleaning tank, in which a turntable is rotatably connected via a central shaft, and a rotary drive assembly is connected to the outer end of the central shaft extending out of the cleaning tank. Multiple expansion shaft groups are arranged in a circular array on the turntable. A large gear disc and a cylinder are fixedly arranged in the cleaning tank, concentrically with the turntable and interacting with the expansion shaft groups. The expansion shaft assembly includes a hollow shaft rotatably connected to the turntable. Multiple key bars are mounted on the hollow shaft in front of the turntable, and elastic rings are fitted around the key bars. A gear meshing with a large gear plate is mounted on the hollow shaft behind the turntable. A push rod is rotatably inserted into the hollow shaft. A frustum block is mounted on the push rod inside the hollow shaft. Each key bar has a beveled groove at its radially inner end that interacts with the frustum block. A connecting rod extending out of the hollow shaft is connected to the rear end of the push rod. A guide wheel is connected to the outer end of the connecting rod. A guide ring groove, consisting of a front arc segment, a rear arc segment, and a transition segment, is provided on the outer surface of the cylinder. The front arc segment is located in the lower half of the cylinder, and the rear arc segment is located in the upper half of the cylinder. A brushing assembly is fixedly installed on the side wall of the cleaning box, and the brushing assembly is located on the outer path of the disc brake disc as it rotates with the expansion shaft assembly.

[0006] As a further feature of the above scheme, it also includes a feeding mechanism, a gripping assembly mechanism, and a distribution mechanism. The gripping assembly mechanism is used to grip and hold multiple disc brake discs pushed out from the feeding mechanism and fit them onto the expansion shaft assembly. The distribution mechanism is used to separate the multiple disc brake discs fitted onto the expansion shaft assembly at equal intervals.

[0007] As a further provision of the above solution, the feeding mechanism includes a support base located in front of the cleaning tank, an ejector seat on the upper surface of the support base, a material hopper connected to the upper surface of the ejector seat, a pusher cylinder on the ejector seat away from the cleaning tank, and a pusher block on the pusher cylinder to neatly push out multiple disc brakes inside the ejector seat.

[0008] As a further feature of the above solution, the material gripping assembly includes a moving block and a transmission component. The moving block moves linearly along the axial direction of the expansion shaft assembly under the action of the transmission component. A rotating device is provided on the moving block, and the output end of the rotating device is connected to a clamping mechanism that clamps multiple disc brakes pushed out from the ejector seat.

[0009] As a further provision of the above scheme, the uniform distribution mechanism includes a fixed top plate, on which a C-shaped frame that moves up and down is connected via a pressing cylinder. A push-pull cylinder is provided on the side end of the C-shaped frame, and a guide plate is connected to the movable end of the push-pull cylinder. Multiple guide grooves in a radiating pattern are provided on the guide plate. The lower end of the C-shaped frame is connected to a groove block, and multiple sliders are slidably arranged in the groove block. Each slider has a guide post fixed on its upper surface that interacts with the corresponding guide groove. Each slider has a movable partition plate fixedly connected to its lower end, and a fixed partition plate fixedly connected to the groove block is provided next to the outermost movable partition plate.

[0010] As a further feature of the above scheme, one end of the multiple guide grooves is gathered together, and the other end of the multiple guide grooves is set apart at equal intervals along the axis of the expansion shaft assembly.

[0011] As a further feature of the above scheme, a limiting ring is provided at the front end of the outer circle of the cylinder. The limiting ring is axially extended backward and fixedly connected to the cylinder via a connecting rod. The connecting rod is flat, so that the flat connecting rod is located in the annular opening between the limiting ring and the cylinder for rotational limiting.

[0012] As a further feature of the above solution, an ultrasonic transducer is provided on the bottom wall of the cleaning tank, and the ultrasonic transducer is connected to an ultrasonic generator outside the cleaning tank via a wire.

[0013] As a further provision of the above solution, the brushing assembly includes an end strip plate fixedly connected to the inner side wall of the cleaning tank. Multiple arc plates are evenly spaced on the end strip plate, and metal bristles are provided on the side of each arc plate. The center of the arc plate coincides with the center of the turntable, so that when the disc brake disc on the expansion shaft rod assembly rotates through the gap between two adjacent arc plates, it is brushed by the metal bristles on its side.

[0014] The disc brake disc high-efficiency cleaning equipment disclosed in this invention mainly consists of five processes during operation: automatic feeding and assembly, equidistant arrangement of disc brake discs, expansion and fixing and self-rotation drive, brushing and ultrasonic cleaning, and unloading and resetting.

[0015] During the automatic feeding and assembly process, the pushing cylinder in the unloading mechanism first pushes out multiple neatly stacked disc brake discs from the bottom of the hopper from the ejector seat. After being pushed out, the clamping mechanism in the material grabbing and assembly mechanism clamps the pushed-out disc brake discs. Then, after the direction is adjusted by the rotating device, they move along the axial direction of the expansion shaft assembly, thus successfully assembling them onto the unexpanded expansion shaft assembly.

[0016] During the equidistant arrangement of disc brake discs, the turntable drives the expansion shaft assembly to rotate to below the distribution mechanism. Then, the downward pressure cylinder of the distribution mechanism pushes the C-frame downward, causing the movable partition plate and the fixed partition plate to be inserted into the gap of the disc brake disc. Then, the push-pull cylinder drives the guide groove plate to move. Through the cooperation of the guide groove and the guide column, multiple movable partition plates are driven to unfold at equal intervals, thereby achieving the uniform distribution of disc brake discs.

[0017] During the expansion and rotation process, the turntable continues to rotate via a rotary drive assembly. During this process, the guide wheel on the expansion shaft assembly moves along the guide ring groove on the cylinder. When the guide wheel enters the front arc section, the push rod moves forward, and the frustum block presses against the inclined groove at the inner end of the key bar, causing the key bar to expand radially. This, in turn, expands and fixes the evenly distributed disc brake discs. Simultaneously, the meshing of the gear with the large gear chain drives the hollow shaft and disc brake discs to rotate.

[0018] During the brushing and ultrasonic cleaning process, multiple expanded and rotating disc brakes are immersed in the cleaning fluid along with the rotating discs and pass through the brushing assembly. The metal bristles on the brushing assembly then thoroughly clean the surface of the rotating disc brakes. After brushing, a row of disc brakes enters the ultrasonic cleaning area, where the cavitation effect generated by the ultrasonic transducer further removes fine dirt.

[0019] Finally, during the unloading and resetting process, the turntable brings the disc brake disc out of the liquid surface, the guide wheel enters the rear arc section, and the expansion shaft assembly is released from its tension. At this time, the operator or robot arm removes the cleaned disc brake disc, completing one cleaning cycle. After completing one cleaning cycle, the equipment is reset to prepare for the next batch of cleaning operations.

[0020] Compared with the prior art, the present invention has the following beneficial effects: The disc brake disc high-efficiency cleaning equipment disclosed in this invention uses a turntable to drive multiple expansion shaft groups to rotate in a cycle. Combined with brushing components and ultrasonic cleaning, it realizes continuous, assembly line cleaning of multiple disc brake discs, which greatly improves cleaning efficiency.

[0021] The expansion shaft assembly in this invention achieves automatic tightening and loosening through its interaction with the guide ring groove, ensuring that the disc brake disc remains stable and does not loosen during the cleaning process. At the same time, the expansion shaft assembly also meshes with the gear and the large gear plate to drive the disc brake disc to rotate. During its rotation, it works with the metal bristles on the brushing component to achieve all-round brushing, cleaning without dead angles and ensuring the cleaning effect of the disc brake disc.

[0022] The present invention further achieves automatic feeding, assembly, and equidistant arrangement of disc brake discs by setting up a feeding mechanism, a material grabbing and assembly mechanism, and a uniform distribution mechanism, which work together in a high degree to reduce manual intervention and improve the degree of automation and operational consistency.

[0023] The cleaning equipment disclosed in this invention integrates functions such as brushing, ultrasonic cleaning, automatic feeding, and uniform distribution. The equipment has a compact structure, occupies a small area, and is suitable for modern production lines. It also combines mechanical brushing with ultrasonic cavitation to effectively remove oxide scale, oil stains, and sintering residues from the surface of disc brake discs, thus ensuring the cleaning effect.

Detailed Implementation

[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The following will refer to the appendix... Figures 1-10 This application will be described in detail with reference to the embodiments. Example 1

[0028] Example 1 discloses a high-efficiency disc brake disc cleaning device, as shown in the attached figure. Figures 1-4The main body of the equipment includes a cleaning tank 1 with an opening at the top. An electrical control box 2 for controlling its operation and a drain pipe 3 for wastewater discharge are located on the side of the cleaning tank 1. A cylinder 4 is fixedly installed at the center of the rear end face of the cleaning tank 1. A large gear disc 5 is concentrically fixedly connected to the front end of the cylinder 4. Both the cylinder 4 and the large gear disc 5 have a central hole 501 at their centers. A central shaft 6, extending from the rear side of the cleaning tank 1, is rotatably mounted in the central hole 501 via an internal bearing. A rotary drive assembly 7 is connected to the rear end of the central shaft 6, and a turntable 8 located inside the cleaning tank 1 is fixedly connected to the front end of the central shaft 6. The rotary drive assembly 7 can be a combination of a motor and a reducer or a motor and a synchronous belt, as long as it can drive the turntable 8 to rotate precisely by a certain angle each time.

[0029] Multiple bearings are arranged in a circular array on the turntable 8. The number of bearings can be set between 3 and 8, depending on the actual situation. Each bearing is rotatably connected to an expansion shaft assembly 9. Before expansion, the mounting hole of the disc brake disc 100 can be easily inserted into the expansion shaft assembly 9 without obstruction. After the expansion shaft assembly 9 expands, it can tighten and fix the disc brake disc 100.

[0030] Reference Appendix Figure 5 The expansion shaft assembly 9 includes a hollow shaft 901 rotatably connected to the turntable 8 via bearings. A gear 902 meshing with the large gear disc 5 is located at the rear end of the hollow shaft 901. Two to four keyway grooves are circumferentially formed on the hollow shaft 901 in front of the turntable 8. A key 903 is installed in each keyway groove, and an elastic ring 904 is fitted around the hollow shaft 901 to radially lock all the keyway grooves inwards. A push rod 905 is rotatably inserted at the rear end of the hollow shaft 901, and one or two frustum blocks 906 are fixedly mounted on the push rod 905. A beveled groove interacting with the frustum block 906 is formed at the radially inner end of each key 904. A connecting rod 907 is connected to the rear end of the push rod 905 extending out of the hollow shaft 901, and a guide wheel 908 radially oriented towards the cylinder 4 is connected to the rear end of the connecting rod 907.

[0031] A guide ring groove 40 is formed on the outer circumference of the cylinder 4, and the guide wheels 908 on all the expansion shaft rod assemblies 9 interact with the guide ring groove 40. Specifically, the guide ring groove 40 includes a front arc segment 401 and a rear arc segment 402. The front arc segment 401 is located in the lower half of the cylinder 4, and the rear arc segment 402 is located in the upper half of the cylinder 4. The two ends of the front arc segment 401 and the rear arc segment 402 are connected by a transition section 403. In addition, to prevent the guide wheel 908 and the connecting rod 907 from rotating with the hollow shaft 901, a limiting ring 41 is provided at the front end of the outer circle of the cylinder 4. The limiting ring 41 is axially extended backward and fixedly connected to the cylinder 4 through several connecting rods 42. At the same time, the connecting rod 907 is set to be flat, so that the flat connecting rod 907 is located in the annular opening between the limiting ring 41 and the cylinder 4 for rotational limitation, preventing the connecting rod 907 from rotating synchronously with the hollow shaft 901 and causing the guide wheel 908 to slip out of the guide ring groove 40.

[0032] Reference Appendix Figure 1 Appendix Figure 3 and attached Figure 6 In this embodiment 1, a brushing assembly 10 is also provided on the side wall of the cleaning tank 1. The brushing assembly 10 includes an end strip plate 101 fixedly connected to the inner side wall of the cleaning tank 1. Multiple arc plates 102 are evenly spaced on the end strip plate 101, and a large number of metal brush filaments 103 are provided on the side of the arc plates 102. At the same time, the center of the arc plate 102 coincides with the center of the turntable 8. When the disc brake disc 100 on the expansion shaft rod assembly 9 rotates through the gap between two adjacent arc plates 102, it can be effectively brushed by the metal brush filaments 103 on its side. Finally, in this embodiment 1, an ultrasonic transducer 11 is also installed on the bottom wall of the cleaning tank 1, and the ultrasonic transducer 11 is connected to an ultrasonic generator (not shown in the figure) outside the cleaning tank 1 through a wire.

[0033] In the operation of the high-efficiency disc brake cleaning equipment disclosed in Embodiment 1, when the expansion shaft assembly 9 rotates with the turntable 8 to the upper part and the guide wheel 908 interacts with the rear arc segment 402 in the guide ring groove 40, the operator inserts multiple disc brake discs 100 into it and arranges them at equal intervals according to the installation requirements. After the loading is completed, the turntable 8 continues to drive the expansion shaft assembly 9 to rotate stably. When the expansion shaft assembly 9 passes through the transition section 403 and interacts with the front arc segment 401, the expansion shaft assembly 9 will expand outward under the action of the guide wheel 908 and the front arc segment 401, thereby tightening and fixing the multiple disc brake discs 100, and the tightened and fixed disc brake discs 100 will rotate together with the expansion shaft assembly 9.

[0034] Subsequently, the disc brake disc 100 is immersed in the cleaning fluid in the cleaning tank 1 as the expansion shaft assembly 9 rotates. Simultaneously, it enters the space between the two arc plates 102 in the adjacent brushing assembly 10 and comes into contact with the metal bristles 103. As the expansion shaft assembly 9 rotates around the turntable 8, the meshing transmission between the gear 902 and the large gear 5 also causes the expansion shaft assembly 9 to rotate around its own central axis. During this rotation, the disc brake disc 100 also rotates continuously. This continuous rotation of the disc brake disc 100 ensures full contact and brushing with the metal bristles 103, effectively cleaning and removing rust and stains from its surface.

[0035] Finally, the cleaned disc brake disc 100 will exit the cleaning assembly 10 along with the expansion rod assembly 9 and rotate to directly above the ultrasonic transducer 11. At this time, the ultrasonic transducer 11 operates in the cleaning fluid to perform ultrasonic cleaning on the disc brake disc 100, ensuring that the surface of the disc brake disc 100 is completely clean. After cleaning, the disc brake disc 100 is rotated out of the cleaning tank, and then the expansion rod assembly 9 will release its tension on the disc brake disc 100. The operator can then remove the cleaned disc brake disc 100. Example 2

[0036] Example 2 discloses a high-efficiency disc cleaning device that is further optimized based on Example 1. The similarities between it and Example 1 will not be described again.

[0037] This embodiment 2 also includes a feeding mechanism 12, a material gripping assembly mechanism 13, and a uniform distribution mechanism 14. The automatic disc brake disc feeding mechanism 12 includes a support base 121 located in front of the cleaning tank 1. The upper surface of the support base 121 is provided with a feeding seat 122. The upper surface of the feeding seat 122 is provided with a hopper 123 for neatly stacking disc brake discs. A feeding channel for receiving the disc brake discs 100 at the bottom of the feeding seat 122 is opened on the upper surface of the feeding seat 122. At the same time, a feeding cylinder 124 is provided on the feeding seat 122 on the side away from the cleaning tank 1. The telescopic end of the feeding cylinder 124 is provided with a pushing block (not shown in the figure) located in the feeding channel and neatly pushing out multiple disc brake discs 100 at one time.

[0038] Reference Appendix Figure 1 Appendix Figure 2 and attached Figure 7The material gripping assembly 13 includes a linear groove located at the upper right side of the cleaning tank 1. A lead screw 131 and a guide rod, parallel to the expansion shaft assembly 9, are arranged in the linear groove. One end of the lead screw 131 is connected to a lead screw motor 132 mounted on the cleaning tank 1. A moving block 133 is arranged in the linear groove. The lower end of the moving block 133 has a threaded hole that interacts with the lead screw 131 and a guide hole that interacts with the guide rod. A rotating device 134 is then connected to the moving block 133. This rotating device 134 can be a rotary motor or a rotary cylinder. A C-shaped clamping plate 135 is connected to the output end of the rotating device 134. A clamping cylinder 136 is mounted on the upper end of the C-shaped clamping plate 135. A movable clamping plate 137, which cooperates with the C-shaped clamping plate 135, is provided at the telescopic end of the clamping cylinder 136 to clamp multiple disc brake discs 100.

[0039] Reference Appendix Figure 3 Appendix Figure 8 ~Appendix Figure 10 The uniform distribution mechanism 14 includes a top plate 141 positioned directly above the turntable 8 and fixedly connected to the cleaning tank 1. A downward pressing cylinder 142 is mounted on the upper surface of the top plate 141. A C-shaped frame 143 is connected to the lower end of the downward pressing cylinder 142. A push-pull cylinder 140 is mounted on the side end of the C-shaped frame 143. The movable end of the push-pull cylinder 140 is connected to a guide plate 144 that can move left and right. Multiple radiating guide grooves 145 are formed on the guide plate 144. One end of the multiple guide grooves 145 is gathered together, and the other end is evenly spaced along the axis of the expansion shaft assembly 9.

[0040] A groove block 146 is connected to the lower end of the C-frame 143. A sliding block 147, equal in number to the guide groove 145, is slidably mounted in the groove block 146. Each sliding block 147 has a guide post 148 fixed to its upper surface, which interacts with the corresponding guide groove 145. Finally, a movable partition plate 149 is fixedly connected to the lower end of each sliding block 147. A fixed partition plate 150, fixedly installed with the groove block 146, is located beside the outermost movable partition plate 149. Both the movable partition plate 149 and the fixed partition plate 150 have thin blade-like lower ends, allowing them to be easily inserted into the gap between two adjacent disc brake discs 100.

[0041] The feeding mechanism 12, the gripping assembly mechanism 13, and the evenly distributing mechanism 14 disclosed in this embodiment 2 constitute a continuous automatic feeding and arrangement scheme. During its operation, the pushing cylinder 124 is first activated to push out multiple disc brake discs 100 that fall from the hopper 123 into the ejector seat 122 in one neat motion. The ejected multiple disc brake discs 100 are clamped and fixed by the moved C-shaped clamping plate 135 and the movable clamping plate 137.

[0042] Under the action of the lead screw drive, the moving block 133 moves towards the expansion shaft assembly 9, and during the start-up process, it is driven to rotate 90° by the rotating device 134, so that the mounting hole of the clamped disc brake disc 100 is aligned linearly with the expansion shaft assembly 9. Then, under the action of the lead screw drive, it is linearly transported to the set position, so that multiple disc brake discs 100 are fitted onto the expansion shaft assembly 9. After the disc brake discs 100 are fitted and loaded, the clamping force is released and they are reset.

[0043] Subsequently, the rotation of the turntable 8 causes the expansion shaft assembly 9, which houses the disc brake discs 100, to rotate to its uppermost position, positioning the multiple disc brake discs 100 directly below the distribution mechanism 14. Then, the downward pressure cylinder 142 is activated, simultaneously pushing multiple partition plates 149 into the gaps between adjacent disc brake discs 100. Next, the push-pull cylinder 140 is activated, causing the guide plate 144 to move left and right. During this movement, the guide plate 144, through the interaction between the guide groove 145 and the guide post 148, evenly separates the partition plates 149 and pushes the multiple disc brake discs 100 to unfold at equal intervals. After the multiple disc brake discs 100 are unfolded, the distribution mechanism 14 separates and resets. The turntable 8 then drives the expansion shaft assembly 9 and the disc brake discs 100 to rotate and tighten, securing them. They then enter the brushing assembly 10 for brushing, followed by ultrasonic cleaning, and finally exit through the upper opening of the cleaning box 1. They can then be removed by personnel, or with the assistance of a robotic arm or robot.

[0044] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
