Description

Technical Field

[0001] The present application relates to the technical field of brake disc surface treatment, and in particular to a brake disc surface strengthening treatment method and system based on laser cladding. Background Art

[0002] Reference Figure 1 A brake disc 100 is provided with a through hole 101 at the axis of the brake disc 100 for reducing the overall weight of the brake disc 100.

[0003] The brake disc, also known as the brake disc or brake disc, is an important component in the disc brake system, usually made of strong metal materials such as cast iron or steel. The brake disc is a ring-shaped device that rotates with the wheel during vehicle driving.

[0004] The main function of the brake disc is to help the vehicle slow down or stop. When the driver steps on the brake pedal, the brake caliper clamps the brake disc, generating braking force through friction to stop the wheels from turning, thereby slowing down or stopping the vehicle.

[0005] During use, the brake disc will gradually wear due to friction. In order to improve the wear resistance of the brake disc, reduce the emission of harmful particulate matter during braking and improve safety, the brake disc is usually subjected to surface strengthening treatment during processing.

[0006] However, currently, when the surface of a brake disc is processed, laser cladding is usually performed on the outer surface of a single brake disc, and the efficiency of laser cladding on the surface of the brake disc is low. Summary of the invention

[0007] In order to improve the efficiency of laser cladding of brake discs, the present application provides a brake disc surface strengthening treatment method and system based on laser cladding.

[0008] In the first aspect, the present application provides a brake disc surface strengthening treatment system based on laser cladding, which adopts the following technical solutions: A brake disc surface strengthening treatment system based on laser cladding includes a frame, a laser head is slidably connected to the frame, a powder feeder is connected to the laser head, a workbench is arranged below the frame, a support table is rotatably connected to the workbench, processing plates are arranged at circumferentially equal intervals on the support table, two sleeve rods are rotatably connected to the processing plates, the diameter of the sleeve rods is adapted to the through hole, a support ring for supporting the brake disc is arranged at the lower end of the sleeve rod, and a fixing part for fixing the brake disc is slidably connected to the sleeve rod.

[0009] By adopting the above technical solution, any one side of the two brake discs is put on different sleeve rods, and then the corresponding brake discs are clamped by using the fixing part. At this time, the two sleeve rods are operated to drive the corresponding brake discs to rotate, and then the laser head can be operated to slide, and then the upper surface of the brake disc is laser clad. After completing the laser cladding of one of the brake discs, the laser head can continue to be operated to move toward the axis of the other brake disc, and then the laser cladding of the other brake disc is completed. The efficiency of laser cladding of the brake disc is high, and the two brake discs can be laser clad in a short time.

[0010] Optionally, the fixing part includes a double-headed cylinder, which is horizontally arranged inside the sleeve rod and slidably connected along the height direction of the sleeve rod. A fixing plate for fixing the brake disc is provided on the piston rod of the double-headed cylinder, and a bonding layer for bonding with the surface of the brake disc is provided on the lower end of the fixing plate. A clearance hole for the extension of the fixing plate is provided on the sleeve rod, and the piston rod of the double-headed cylinder can extend to the outside of the sleeve rod when extended.

[0011] By adopting the above technical solution, the fixing plate is pressed against the upper surface of the brake disc by sliding the double-headed cylinder, and then the brake disc is pressed between the sleeve rod and the support ring to complete the fixation of the brake disc. The structure is simple and the fixation is convenient.

[0012] Optionally, a tensioning cylinder is vertically arranged inside each sleeve rod, and the piston rod of the tensioning cylinder is fixedly connected to the cylinder barrel of the double-head cylinder.

[0013] By adopting the above technical solution, the tensioning cylinder can be used to drive the cylinder barrel of the double-head cylinder to move, thereby driving the fixing plate to move, and then pressing the brake disc between the sleeve rod and the support ring to complete the fixation of the brake disc. The structure is simple and the fixation is convenient.

[0014] Optionally, the processing plate is rotatably connected to two gears, the two gears are meshed with each other, and the sleeve rods are arranged on the upper end surfaces of the corresponding gears. A motor 1 is arranged on the other side of the processing plate, and the output shaft of the motor 1 passes through the processing plate and is fixedly connected to the axis center of one of the gears.

[0015] By adopting the above technical solution, the output shaft of the motor is controlled to rotate, thereby driving a gear to rotate, thereby driving another gear to rotate, and thereby driving two brake discs to rotate. The structure is simple and the driving is convenient.

[0016] Optionally, the frame is rotatably connected to a threaded rod, and a limiting rod is also provided on the frame and is arranged parallel to the threaded rod. The laser head is threadably connected to the threaded rod, and the laser head is sleeved on the outside of the limiting rod.

[0019] By adopting the above technical solution, the worm can be driven to rotate by manipulating the rotation of the second output shaft of the motor, which in turn drives the worm wheel to rotate, which in turn drives the threaded rod to rotate, and then drives the laser head to move. The worm wheel and the worm have a self-locking function, which can effectively prevent the threaded rod from rotating due to external force, thereby improving the stability of the laser head movement.

[0020] Optionally, a manipulator for clamping the brake disc is provided on one side of the workbench.

[0021] By adopting the above technical solution, after the upper end surface of the brake disc is laser clad, the brake disc can be removed from the sleeve rod by a robot, then turned over and laser clad again, which saves manpower and improves the efficiency of laser cladding of the brake disc.

[0022] In a second aspect, the present application provides a brake disc surface strengthening treatment method based on laser cladding, comprising the following steps: S1: Two brake discs are mounted on different rods; S2: Operate the piston rods of the double-headed cylinders to extend, and operate the piston rods of the tensioning cylinders to retract, so that the brake discs are pressed tightly against the corresponding gears; S3: Rotate the support table to move the brake disc to be clad to the bottom of the laser head; S4: As soon as the motor is turned on, the laser head and the powder feeder are operated to start laser cladding treatment on the surface of the brake disc; S5: The second motor is turned on to drive the laser head to move, and the laser cladding process of one of the brake discs is completed; S6: As the laser head continues to move, the laser cladding process of another brake disc is completed; S7: Rotate the processed brake disc to a position close to the manipulator, remove the brake disc from the sleeve rod, turn the brake disc over and put it back on the sleeve rod; S8: Repeat S2 to S6 to complete the surface strengthening treatment of the brake disc.

DETAILED DESCRIPTION

[0031] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0032] In a first aspect, an embodiment of the present application discloses a brake disc surface strengthening treatment system based on laser cladding.

[0033] Reference Figure 2 and Figure 3 A brake disc surface strengthening treatment system based on laser cladding includes a frame 1 and a controller 4. A laser head 11 is slidably connected to the frame 1, and a powder feeder 12 is connected to the laser head 11. A workbench 2 is arranged below the frame 1, and a support platform 21 is rotatably connected to the workbench 2. Processing plates 22 are arranged at equal intervals in the circumferential direction of the support platform 21. Two sleeve rods 23 are rotatably connected to the processing plate 22. The diameter of the sleeve rod 23 is adapted to the through hole 101. A support ring for supporting the brake disc 100 is arranged at the lower end of the sleeve rod 23. Before processing the brake disc 100, any one side of the two brake discs 100 can be put on different sleeve rods 23.

[0034] Reference Figure 4 and Figure 5 The sleeve rod 23 is slidably connected with a member for fixing the brake disc 100 (refer to Figure 2 ) of the fixing part, the fixing part includes a double-headed cylinder 231, and the double-headed cylinder 231 is electrically connected to the controller 4 (refer to Figure 3 ), the double-headed cylinder 231 is horizontally arranged inside the sleeve rod 23, and the double-headed cylinder 231 is slidably connected along the height direction of the sleeve rod 23. The sleeve rod 23 is provided with a clearance hole 233 for the fixing plate 234 to extend. By operating the two piston rods of the double-headed cylinder 231 to extend at the same time, the piston rods of the double-headed cylinder 231 are provided with a fixing plate 100 (refer to Figure 2 ) a fixing plate 234, extending the fixing plate 234 to the outside of the sleeve rod 23; Each sleeve rod 23 is vertically provided with a tensioning cylinder 232 inside, the tensioning cylinder 232 is electrically connected to the controller 4, and the piston rod of the tensioning cylinder 232 is fixedly connected to the cylinder barrel of the double-headed cylinder 231. By operating the piston rod of the tensioning cylinder 232 to retract, the cylinder barrel of the double-headed cylinder 231 is driven to move, and then the fixing plate 234 is driven to move. The lower end of the fixing plate 234 is provided with a brake disc 100 (refer to Figure 2 ) surface, and then the bonding layer and the brake disc 100 (refer to Figure 2 ) and tighten the upper surface of the brake disc 100 (refer to Figure 2 ) is pressed against the sleeve rod 23 and the support ring to complete the brake disc 100 (refer to Figure 2 ) has a simple structure and is easy to fix.

[0035] Reference Figure 2 and Figure 3A motor 3 5 is provided on the workbench 2, and the output shaft of the motor 3 5 is fixedly connected to the axis center of the support platform 21. The motor 3 5 is electrically connected to the controller 4. The controller 4 controls the output shaft of the motor 3 5 to rotate, thereby driving the support platform 21 to rotate, and rotating the brake disc 100 to be processed to the bottom of the laser head 11.

[0036] Reference Figure 3 and Figure 6 , two gears 221 are rotatably connected to the processing plate 22, and the two gears 221 are meshed with each other. The sleeve rods 23 are all arranged on the upper end surfaces of the corresponding gears 221. A motor 222 is arranged on the other side of the processing plate 22, and the motor 222 is electrically connected to the controller 4. The output shaft of the motor 222 passes through the processing plate 22 and is fixedly connected to the axis of one of the gears 221; the output shaft of the motor 222 is controlled by the controller 4 to rotate, thereby driving one of the gears 221 to rotate. Since the two gears 221 are meshed with each other, the other gear 221 is driven to rotate, thereby driving the two sleeve rods 23 to rotate, thereby driving the two brake discs 100 located below the laser head 11 to rotate. The structure is simple and the driving is convenient.

[0037] Then, the laser head 11 and the powder feeder 12 can be manipulated to perform laser cladding on the outer surface of the brake disc 100 . After the inner ring of one of the brake discs 100 is polished, the laser head 11 can be manipulated to move.

[0038] The frame 1 is rotatably connected to a threaded rod 13, and a limit rod 14 is also provided on the frame 1 and is arranged parallel to the threaded rod 13. The laser head 11 is threadedly connected to the threaded rod 13, and the laser head 11 is sleeved on the outside of the limit rod 14; the frame 1 is rotatably connected to a worm 15, and a motor 2 16 is provided on the frame 1, and the motor 2 16 is electrically connected to the controller 4, and the output shaft of the motor 2 16 is fixedly connected to the axis of the worm 15. The frame 1 is also rotatably connected to a worm wheel 17 meshing with the worm wheel 15, and the worm wheel 17 is sleeved on the threaded rod 13. The worm 15 can be driven to rotate by the controller 4 to control the rotation of the output shaft of the motor 2 16, thereby driving the worm wheel 17 to rotate, thereby driving the threaded rod 13 to rotate, and thereby driving the laser head 11 to move. At this time, the laser head 11 moves slowly toward the outer ring direction of the brake disc 100 currently being processed. The worm wheel 17 and the worm 15 have a self-locking function, which can effectively avoid the situation where the threaded rod 13 rotates due to external force, thereby improving the stability of the movement of the laser head 11.

[0039] During the movement, the laser head 11 continues to perform laser cladding processing on the brake disc 100. When the laser head 11 moves to the outermost circle of the brake disc 100 and the outermost circle of the brake disc 100 is processed, the laser head 11 can be operated to be closed first, and then the motor 2 16 continues to rotate to move the laser head 11 to the outer circle of another brake disc 100, and the laser head 11 is operated to be turned on again to perform laser cladding processing on the other brake disc 100 until the laser head 11 is moved to the inner circle of the other brake disc 100 to complete the processing of the upper surfaces of the two brake discs 100. The efficiency of laser cladding on the brake disc 100 is high, and the two brake discs 100 can be laser clad in a short time.

[0040] Among them, laser cladding treatment of the brake disc 100 is a prior art and will not be described in detail in this embodiment. In addition, in this embodiment, a laser head 11 that can rotate freely and adjust the height is preferred, that is, the angle and height of the laser head 11 can be adjusted before processing the brake disc 100, which is also a prior art and will not be described in detail in this embodiment.

[0041] Reference Figure 1 and Figure 3 A manipulator 3 for clamping the brake disc 100 is provided on one side of the workbench 2, and the manipulator 3 is electrically connected to the controller 4.

[0042] Reference Figure 1 and Figure 6 The controller 4 controls the manipulator 3 to remove the brake disc 100 from the sleeve rod 23, and then the brake disc 100 after the outer surface of one side is processed is turned over, and then the other side surface to be processed is placed on top and sleeved on the upper end of the sleeve rod 23, and then the brake disc 100 is fixed again and laser cladding is performed again. The efficiency of laser cladding of the brake disc 100 is relatively high.

[0043] The implementation principle of the brake disc surface strengthening treatment system based on laser cladding in the embodiment of the present application is as follows: any one side of the two brake discs 100 is put on different sleeve rods 23, and then the corresponding brake discs 100 are clamped by using the fixing part. At this time, the two sleeve rods 23 are manipulated to drive the corresponding brake discs 100 to rotate, and then the laser head 11 can be manipulated to perform laser cladding on the surface of the brake disc 100. By manipulating the laser head 11 to slide, different positions on the upper surface of the brake disc 100 are processed. After one of the brake discs 100 is processed, the laser head 11 can be manipulated to continue to be manipulated to the other brake disc The robot 3 then moves along the axis of the sleeve rod 23 to complete the laser cladding process on the other brake disc 100. The laser cladding process on the brake disc 100 is efficient and the two brake discs 100 can be laser clad in a short time. The robot 3 can then be used to remove the brake disc 100 from the sleeve rod 23, and then the brake disc 100 with the outer surface processed on one side turned over, and then the other side surface to be processed is placed on top and sleeved on the upper end of the sleeve rod 23. The brake disc 100 is then fixed again and laser clad again. The laser cladding process on the brake disc 100 is efficient.

[0044] In a second aspect, the present application provides a brake disc surface strengthening treatment method based on laser cladding, comprising the following steps: S1: Mounting two brake discs 100 on different sleeve rods 23; S2: The piston rods of the double-headed cylinder 231 are extended, and the piston rods of the tensioning cylinder 232 are retracted, so that the brake discs 100 are pressed against the corresponding gears 221; S3: rotating the support platform 21 to move the brake disc 100 to be clad to the bottom of the laser head 11; S4: The motor 222 is turned on, and the laser head 11 and the powder feeder 12 are operated to start laser cladding treatment on the surface of the brake disc 100; S5: The second operating motor 16 is turned on to drive the laser head 11 to move, and the laser cladding process of one of the brake discs 100 is completed; S6: As the laser head 11 continues to move, the laser cladding process on another brake disc 100 is completed; S7: rotating the processed brake disc 100 to a position close to the manipulator 3, removing the brake disc 100 from the sleeve rod 23, turning the brake disc 100 over and putting it back on the sleeve rod 23; S8: Repeat S2 to S6 to complete the surface strengthening treatment of the brake disc 100.
