[0033] Example 1

[0034] like Figure 1-Figure 7 As shown:

[0035] A mechatronic wheelset laser cleaning device that is convenient for fixing workpieces includes a machine base 1, two side walls of the machine base 1 are arranged opposite to each other, a conveyor belt 11 is installed on the inner side of the machine base 1, the conveyor belt 11 is arranged along the length direction of the machine base 1, two ends of a conveying shaft on the conveyor belt 11 are respectively installed on the two side walls of the machine base 1, the conveying shaft is rotatably connected to the machine base 1, and the conveying shaft is connected to a conveying motor. The conveyor belt 11 is a commonly used equipment and can realize the conveyance of workpieces, which will not be described in detail here.

[0036] like Figure 3 and Figure 4As shown, a lift frame 21 that can be raised and lowered is provided above the conveyor belt 11, and two opposite inner walls of the lift frame 21 arranged along the width direction of the base 1 are respectively provided with first slide grooves 22, and a bidirectional screw 25 is rotatably installed in the first slide groove 22, one end of the bidirectional screw 25 is connected to the output shaft of the first motor 24, and two cross plates 26 are symmetrically arranged between the bidirectional screws 25, and the cross plates 26 are vertically arranged to the bidirectional screws 25, and both ends of the cross plates 26 are respectively connected to the first slider 23 slidably connected to the first slide groove 22, and the first slider 23 is threadedly connected to the bidirectional screw 25, and the positive tooth section and the negative tooth section of each bidirectional screw 25 are respectively screwed to a first slider 23.

[0037] The middle position of the bidirectional screw 25 is connected to the first slide groove 22 through a fixed seat, and the fixed seat is installed in the first slide groove 22. The bidirectional screw 25 is rotatably connected to the fixed seat. The fixed seat provides support for the bidirectional screw 25 to avoid radial runout of the bidirectional screw 25, ensuring that the first slider 23 and the bidirectional screw 25 are stably matched and move smoothly in the first slide groove 22.

[0038] In this embodiment, the bidirectional screw 25 can be provided as one or two symmetrical screws, which can drive the transverse plate 26 to move transversely in the lifting frame 21 .

[0039] A positioning block 29 is respectively arranged on the opposite surfaces of the two horizontal plates 26, and a V-shaped positioning groove 30 is opened on the opposite surfaces of the positioning blocks 29. A rubber anti-skid layer can be arranged on the surface of the positioning groove 30. The opposite surfaces of the positioning blocks 29 are connected to the second motor 27, and the output end of the second motor 27 is connected to the positioning block 29 through a rotating shaft 28. The rotating shaft 28 passes through the horizontal plate 26 and is rotatably connected to the horizontal plate 26. The second motor 27 is installed on the horizontal plate 26.

[0040] The first motor 24 can rotate the bidirectional screw 25 and move the first slider 23 in the first slide groove 22, so that the two cross plates 26 move synchronously toward or away from each other under the drive of the first slider 23, and then the two positioning blocks 29 move toward each other to clamp the workpiece or move away from each other to release the workpiece.

[0041] The positioning block 29 with the V-shaped positioning groove 30 clamps the wheelset end 92, and can position and fix the wheelset workpiece, thereby improving the scope of application.

[0042] The second motor 27 is started, and the second motor 27 drives the positioning block 29 to rotate axially through the rotating shaft 28, thereby driving the wheelset workpiece clamped between the two positioning blocks 29 to flip, thereby facilitating the cleaning of the wheelset tread portion 91 or other positions of the wheelset workpiece.

[0043] In this embodiment, the second motor 27 can be set to one or to two symmetrical ones. If the number of the second motor 27 is one, it is installed on any horizontal plate 26, and the other horizontal plate 26 and the positioning block 29 ensure rotational connection; if the number of the second motors 27 is two, it is necessary to ensure that when the positioning blocks 29 driven by the two second motors 27 clamp the workpiece, the direction of driving the workpiece to flip is consistent to avoid rotational conflict.

[0044] like Figure 5 As shown, the inner side walls of the base 1 are respectively provided with vertically arranged lifting grooves 41, and the two lifting grooves 41 are arranged opposite to each other. A first screw 43 is provided in the lifting groove 41, and the first screw 43 is connected to a third motor 44. The first screw 43 is rotatably connected to the lifting groove 41, and a lifting block 42 is slidably connected in the lifting groove 41, and the lifting block 42 is threadedly connected to the first screw 43, and one end of the lifting block 42 extends to the outside of the lifting groove 41 and is connected to the lifting frame 21.

[0045] The output shaft of the third motor 44 is connected to a driving bevel gear 46 disposed in the lifting slot 41 through a driving shaft 45 . The end of the first screw 43 is sleeved with a driven bevel gear 47 meshing with the driving bevel gear 46 . The driving shaft 45 is rotatably connected to the base 1 .

[0046] The third motor 44 can drive the driving shaft 45 and the active bevel gear 46 to rotate, and then drive the driven bevel gear 47 and the first screw 43 to rotate, so that the lifting block 42 can move up and down, and the distance between the wheelset workpiece and the laser cleaner 12 can be adjusted according to the height of the wheelset workpiece.

[0047] The lifting block 42 is in a T-shape, and the lifting slot 41 is in a T-shape, which can prevent the lifting block 42 from being separated from the lifting slot 41 when sliding, and limit the lifting block 42.

[0048] The opposite inner walls of the base 1 are respectively provided with horizontally arranged second slide grooves 51, in which second slide blocks 52 are slidably connected, and the second slide blocks 52 are fixedly connected to the telescopic end of the first cylinder 53. A support plate 54 is connected between the two oppositely arranged second slide blocks 52, and the two ends of the support plate 54 are respectively connected to the two second slide blocks 52.

[0049] The first cylinder 53 can drive the second slider 52 to move forward and backward, and further drive the laser cleaner 12 to move forward and backward, thereby increasing the cleaning range of the wheelset workpiece.

[0050] A third slide groove 61 is provided at the bottom of the support plate 54, and a third slider 62 is slidably connected in the third slide groove 61. The third slider 62 is fixedly connected to the telescopic end of the second cylinder 63. The second cylinder 63 is installed inside the third slide groove 61. A connecting block 31 is provided at the bottom of the third slider 62, and the connecting block 31 is connected to the laser cleaner 12 through a quick-release assembly.

[0051] The second cylinder 63 can drive the third slider 62 to move left and right, and further drive the laser cleaner 12 to move left and right, which can further increase the cleaning range and enable the wheelset workpiece to be cleaned in all directions.

[0052] The longitudinal sections of the third slide groove 61 and the third slider 62 can be set to a T shape or other structure with an anti-drop limit, which can prevent the third slider 62 from falling in the third slide groove 61 or the travel path of the third slider 62 that works for a long time from being offset from the center line of the third slide groove 61, thereby ensuring that the third slider 62 drives the laser cleaner 12 to move smoothly.

[0053] like Figure 1 , Figure 5 and Figure 6 As shown, the quick-release assembly includes a mounting block 33 connected to the top of the laser cleaner 12 , a mounting groove 32 is formed at the bottom of the connecting block 31 , and the mounting block 33 is disposed in the mounting groove 32 .

[0054] A moving opening 35 penetrating the connecting block 31 is formed on the side wall of the mounting groove 32, a slot 34 corresponding to the moving opening 35 is formed on the surface of the mounting block 33 near the moving opening 35, a moving rod 36 is movably installed in the moving opening 35, one end of the moving rod 36 is connected to a ball 39, and the ball 39 can be inserted into the slot 34 under the drive of the moving rod 36, the other end of the moving rod 36 extends to the outside of the moving opening 35 and is connected to a moving plate 37, a first spring 38 sleeved on the outside of the moving rod 36 is provided between the moving plate 37 and the outer wall of the connecting block 31, and the top of the mounting block 33 near the moving opening 35 is set as an arc surface.

[0055] A groove 71 is formed on the inner top surface of the mounting groove 32 , and a push rod 72 is slidably connected in the groove 71 . The top of the push rod 72 is connected to the inner top surface of the groove 71 via a second spring 73 , and the bottom of the push rod 72 is connected to a push plate 74 located above the mounting block 33 .

[0056] When installing the laser cleaner 12, when the mounting block 33 is inserted into the mounting groove 32, the arc surface on the top of the mounting block 33 is squeezed against the surface of the sphere 39, and the sphere 39 slides relative to the arc surface. The sphere 39 pushes the moving rod 36 to move outward, and the two ends of the first spring 38 are respectively fixedly connected to the outer wall of the connecting block 31 and the moving plate 37. The moving rod 36 moves outward, the first spring 38 is stretched and deformed, and the mounting block 33 gradually moves into the mounting groove 32 until the sphere 39 approaches the slot 34. Under the action of the first spring 38, the moving rod 36 and the sphere 39 are pushed inward, and the sphere 39 is inserted into the slot 34, thereby realizing automatic fixation and quick installation of the laser cleaner 12.

[0057] The laser cleaner 12 in this embodiment is a pulsed laser, and a continuous fiber laser, a carbon dioxide laser, and an ultraviolet laser may also be selected as an alternative. The basic principle of the laser cleaner 12 is to utilize the high energy density of the laser to allow the laser to interact with the contaminants attached to the workpiece substrate and separate them from the workpiece substrate in the form of instantaneous thermal expansion, melting, gas volatilization, etc.

[0058] When the mounting block 33 is inserted into the mounting groove 32, the mounting block 33 pushes the push plate 74 upward, and then the push rod 72 moves upward to compress the second spring 73. After the laser cleaner 12 is installed and fixed, the mounting block 33 of the laser cleaner 12 always pushes the push plate 74, and the second spring 73 remains in a compressed state.

[0059] When disassembling the laser cleaner 12, the movable plate 37 outside the movable rod 36 is pulled, the first spring 38 is stretched, the sphere 39 connected to the movable rod 36 moves outward, and the sphere 39 is separated from the slot 34. At this time, under the action of the second spring 73, the second spring 73 restores its deformation, and the second spring 73 pushes the push rod 72 and the push plate 74 to move downward, thereby pushing the mounting block 33 downward, so that the mounting block 33 is pushed out of the mounting slot 32. After loosening the movable plate 37, the movable rod 36 resets itself under the action of the first spring 38, thereby realizing rapid disassembly of the laser cleaner 12 and facilitating maintenance work.

[0060] Working principle: When working, the mounting block 33 on the top of the laser cleaner 12 is inserted into the mounting slot 32, the mounting block 33 squeezes the push plate 74 and the ball 39, the ball 39 drives the moving rod 36 to move outward, and then drives the moving plate 37 to move outward, so that the first spring 38 is stretched and deformed, the push plate 74 drives the push rod 72 to squeeze the second spring 73 to deform it, when the ball 39 contacts the slot 34, the first spring 38 resets and pushes the ball 39 into the slot 34, so as to realize automatic fixation and rapid installation of the laser cleaner 12; put the workpiece on the conveyor belt 11, and the conveyor belt 11 conveys the workpiece to the bottom of the lifting frame 21, and then starts the third motor 44, the third motor 44 drives the active bevel gear 46 to drive the driven bevel gear 47 to rotate, thereby driving the first screw 43 to rotate, and then driving the lifting block 4 2 and the lifting frame 21 move down, and then start the first motor 24, the first motor 24 drives the bidirectional screw 25 to rotate, and then drives the two cross plates 26 to move toward the middle, and then drives the positioning block 29 to move, the positioning blocks 29 move close to each other to clamp and fix the wheel pair end 92 of the workpiece, and then the third motor 44 is reversed, so that the lifting frame 21, the positioning block 29 and the workpiece move up, and then the laser cleaner 12 is started to clean the workpiece; the first cylinder 53 and the second cylinder 63 can drive the laser cleaner 12 to move forward, backward, left and right, and the second motor 27 can drive the workpiece to flip, and then the workpiece can be cleaned in all directions. The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

Under the drive of the driving motor 83, the driving motor 83 drives the driving roller 81 to rotate via the driving gear 84, the toothed belt 86 and the driven gear 85.

[0064] Friction protrusions are arranged on the outer peripheral surface of the driving roller 81 to increase the degree of friction with the wheelset tread portion 91 , thereby enhancing the driving effect, the smoothness and stability of the rotation of the wheelset tread portion 91 .

[0065] In the present embodiment, the driving roller 81 is provided on only one of the positioning blocks 29, or one driving roller 81 may be provided on each of the two positioning blocks 29 to further improve the smoothness and stability of the rotation of the wheel to the workpiece; or multiple rollers on the two positioning blocks 29 may be set as driving rollers 81, as long as the rotation angle of the driving wheel to the workpiece is consistent and no conflict occurs.

[0066] like Fig. 9 and Fig.10 As shown, the side portions of the driving roller 81 and the rotating roller 82 of the left positioning block 29 extend to the outside of the positioning block 29 , and the side portion of the rotating roller 82 of the right positioning block 29 also extends to the outside of the positioning block 29 .

[0067] When cleaning the wheelset end 92, the driving roller 81 and the rotating roller 82 of the positioning block 29 jointly clamp the outer peripheral surface of the wheelset tread portion 91, and the driving roller 81 is driven by the driving motor 83 to rotate. Then, under the action of friction, the driving roller 81 drives the wheelset tread portion 91 to rotate, and the entire wheelset workpiece rotates. The laser cleaner 12 can clean the wheelset end 92 without too much adjustment, thereby improving the cleaning efficiency and saving time.
