Description

Technical Field

[0001] The invention relates to the field of laser rust removal equipment, in particular to laser rust removal and identification equipment for axle identification plates. Background Art

[0002] The working principle of laser rust removal equipment is to emit a high-energy-density laser beam of a specific wavelength. Pollutants such as rust layers have a high absorption rate for lasers, while the base metal has a low absorption rate or a high reflectivity. The rust layer absorbs light energy and converts it into heat energy, causing the temperature to rise sharply. When the vaporization point is reached, the moisture, rust oxides, etc. in it quickly vaporize and detach from the metal surface. At the same time, the light pressure and light intensity gradient generated by the high-energy-density laser beam weaken the bonding between the rust layer and the base, causing photo-stripping and falling off in the form of fragments. The laser energy may also cause photodecomposition of compounds in the rust layer, and the rust layer rapidly expands after absorbing energy to produce thermal stress, which together with the shock wave formed by the plasma expansion generated by the laser action causes the rust layer to crack, break and peel off.

[0003] Laser rust removal equipment can remove rust from the axle identification plate. The axle identification plate is generally located at the center of the axial end of the axle. When positioning the axle, the existing equipment sets a positioning piece on the workbench to block the front of the axle in the direction of travel for fixing the axle. In this way, when blocking and positioning axles with different wheel diameters, it is difficult to align the identification plate and the rust removal laser machine. Moreover, in order to allow the axle to move on the workbench, one end of the workbench is higher than the other end in the existing technology. When the axle moves too fast on the workbench and encounters the positioning piece, it may collide, jump and detach. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is that it is difficult to align wheel axles with different wheel diameters.

DETAILED DESCRIPTION

[0044] In order for those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with specific embodiments and the accompanying drawings.

[0045] The terms used in the present application are those general terms currently widely used in the art in consideration of the functions regarding the present application, but the terms can be changed according to the intention of those of ordinary skill in the art, precedents, or new technology in the art. Also, specific terms can be selected by the applicant, and in this case, the detailed meanings thereof will be described in the detailed description of the present application. Therefore, the terms used in the specification should not be understood as simple names, but based on the meanings of the terms and the general description of the present application.

[0046] Referring to Figure 1 and Figure 2 , the embodiment provides a laser rust removal identification device for wheel axle identification plate, which comprises a workbench 100, and a wheel rail 101 is arranged on the workbench 100; the workbench 100 has a certain slope when installed, for example, the two ends of the workbench 100 are a first end 102 and a second end 103 respectively, the first end 102 is a starting end, the height of the first end 102 is higher than that of the second end 103, when the wheel axle is placed at the first end 102, the wheel axle will roll to the direction of the second end 103 under the action of gravity, the upper surface of the workbench 100 is marked as a standard surface 104, the wheel axle is marked as a workpiece 10, the wheel rail 101 is below the standard surface 104, and a corresponding groove is arranged on the standard surface 104 of the workbench 100 at the corresponding position of the wheel rail 101, when the workpiece 10 moves on the workbench 100, the flange 11 of the workpiece 10 extends into the inside of the wheel rail 101, and the hub part of the workpiece 10 is in contact with the standard surface 104.

[0047] Please refer to Figures 2 to 4 , the device further comprises a rust removal machine 200, the rust removal machine 200 adopts laser rust removal, and the installation position of the rust removal machine 200 is at one side of the workbench 100, when the wheel axle moves to the corresponding position of the rust removal machine 200 on the workbench 100 and stops, the rust removal machine 200 can perform laser rust removal treatment on the identification plates at both ends of the wheel axle.

[0048] The device further comprises a sliding table 300, a buffer mechanism 400, a contact mechanism 500, and a blocking mechanism 600. The sliding table 300 is arranged on the wheel rail 101 and is movable. The buffer mechanism 400 is installed on the wheel rail 101 and is in abutment with the sliding table 300. The contact mechanism 500 is installed on the sliding table 300. The blocking mechanism 600 is directly installed on the wheel rail 101 and is retractable. The workpiece 10 moves on the workbench 100 from the first end 102 to the second end 103, which is marked as moving in the X direction. In this process, the flange 11 of the workpiece 10 will contact the contact mechanism 500. The workpiece 10 pushes the sliding table 300 to continue moving through the contact mechanism 500. In the process of moving, the sliding table 300 can press the buffer mechanism 400, so that the buffer mechanism 400 is compressed. The buffer mechanism 400 has a spring force acting on the sliding table 300, so that the sliding table 300 exerts a certain counterforce on the workpiece 10 through the contact mechanism 500, so that the speed of the workpiece 10 will not be too fast, avoiding the jumping problem caused by the sudden stop of the workpiece 10 moving too fast. In addition, when the blocking mechanism 600 is extended, it can block the movement of the sliding table 300. By adjusting the position of the blocking mechanism 600, the stopping position of the sliding table 300 can be controlled. In this way, when different workpieces 10 with different wheel diameters are processed, the position of the blocking mechanism 600 is adjusted to control the stopping position of the sliding table 300 and further control the stopping position of the workpiece 10, so that the identification plates at both ends of the workpiece 10 can be aligned with the derusting machine 200 as much as possible, thereby being suitable for workpieces 10 with different wheel diameters.

[0049] Reference Figure 3 The buffer mechanism 400 comprises a guide column 401 installed on the wheel rail 101 and an elastic structure 402 installed on the guide column 401. The guide column 401 penetrates the sliding table 300, and the extension direction of the guide column 401 is parallel to the extension direction of the wheel rail 101. The elastic structure 402 can be a long spring directly sleeved on the outside of the guide column 401. When the sliding table 300 moves in the X direction, the elastic structure 402 can be pressed to deform, and the elastic structure 402 generates a spring force acting on the sliding table 300, thereby increasing the resistance of the sliding table 300 moving in the X direction, and further increasing the resistance of the workpiece 10 moving in the X direction, avoiding the workpiece 10 moving too fast.

[0050] In another embodiment, the elastic structure 402 can be composed of multiple shorter springs, and the multiple springs are slidingly mounted on the slider on the guide column 401, which also increases the resistance of the slide table 300. Another function of the elastic structure 402 is to push the slide table 300 back to the opposite direction of the X direction when the workpiece 10 is separated from the slide table 300 and the contact mechanism 500. In summary, the elastic structure 402 has two functions, one is to control the travel speed of the workpiece 10, and the other is to help the slide table 300 reset when the workpiece 10 is separated.

[0051] Reference Figure 3 As an optional embodiment, the blocking mechanism 600 includes a driving structure 601 and a telescopic structure 602 driven by the driving structure 601. The driving structure 601 is also a hydraulic cylinder, and can also be a push rod motor. The function of the driving structure 601 is to drive the telescopic structure 602 to extend and retract. The entire blocking mechanism 600 can be directly installed on the wheel rail 101, for example, at the bottom of the wheel rail 101. When the driving structure 601 drives the telescopic structure 602 to extend, the top end of the telescopic structure 602 can block the travel of the entire slide table 300, thereby blocking the travel of the workpiece 10 and stopping the workpiece 10.

[0052] As the first embodiment of the blocking mechanism 600, the blocking mechanism 600 is slidingly mounted on the wheel rail 101. By adjusting the position of the blocking mechanism 600 on the wheel rail 101, the stopping position of the slide table 300 can be controlled. In this embodiment, the blocking mechanism 600 has only one driving structure 601 and one telescopic structure 602. The entire blocking mechanism 600 is slidingly mounted on the wheel rail 101. The mounting method can be to install an electric track on the wheel rail 101, and the blocking mechanism 600 is directly installed on the wheel rail 101 through the electric track. When processing workpieces 10 of different wheel diameters, the position of the blocking mechanism 600 is adjusted. The blocking mechanism 600 extends at different positions, which can make the slide table 300 stop at different positions, and the workpiece 10 can also stop at different positions. This can help the identification plate on the workpiece 10 of different wheel diameters to align with the deruster 200.

[0053] Reference Figure 3, as the second embodiment of the blocking mechanism 600, the number of blocking mechanisms 600 is at least two, by selecting different blocking mechanisms 600 to stretch, the stop position of the sliding table 300 can be controlled, in this embodiment, the blocking mechanism 600 is directly fixed and installed on the wheel rail 101, the number of blocking mechanisms 600 is determined according to the types of workpieces 10 processed in daily work, for example, in daily work, there are four types of wheel diameters of workpieces 10 processed, then four blocking mechanisms 600 are selected, the installation positions of the four blocking mechanisms 600 are determined according to the wheel diameters of the workpieces 10, for example, the installation positions of the four blocking mechanisms 600 are marked as the first position 610, the second position 620, the third position 630, and the fourth position 640 respectively, the distances from the first position 610 to the fourth position 640 to the rust removal machine 200 increase in turn, among the four types of wheel diameters of workpieces 10 processed in daily work, when the smallest wheel diameter workpiece 10 is processed, the blocking mechanism 600 at the first position 610 is selected to work, when the largest wheel diameter workpiece 10 is processed, the blocking mechanism 600 at the fourth position 640 is selected to work, in this way, the axial positions of workpieces 10 of different wheel diameters can be aligned with the rust removal machine 200 as much as possible, so that the identification plate at the axial position of the end of the workpiece 10 can be aligned with the rust removal machine 200 as much as possible.

[0054] Please refer to Figure 4 , as an optional embodiment, the contact mechanism 500 includes a lifting shaft 501 installed on the sliding table 300 and capable of lifting, and a rotating wheel 502 rotatably installed on the lifting shaft 501; the workpiece 10 moves along the wheel rail 101 and can contact the rotating wheel 502, and the lifting shaft 501 is lowered to allow the rotating wheel 502 to disengage from the workpiece 10.

[0055] A mounting slot is formed in the sliding table 300, and the lifting shaft 501 is slidably mounted in the sliding table 300 through the mounting slot, when the workpiece 10 is blocked, the lifting shaft 501 is at the highest position, at this time, the rotating wheel 502 installed on the lifting shaft 501 is at the highest position, the flange 11 of the workpiece 10 will contact the rotating wheel 502 when extending into the inside of the wheel rail 101 and moving in the inside of the wheel rail 101, in the process of rolling of the workpiece 10, the lifting shaft 501 can be pushed by the rotating wheel 502, and then the sliding table 300 is pushed to move in the X direction, when it is needed to disengage the workpiece 10 from the contact mechanism 500, the position of the lifting shaft 501 is lowered, at this time, the position of the rotating wheel 502 is also lowered, so as to disengage from the flange 11 of the workpiece 10.

[0056] In this embodiment, the rotating wheel 502 is a special-shaped wheel, and the number of the rotating wheel 502 is two. The diameter of one end of the rotating wheel 502 close to each other is smaller than the diameter of the other end far from each other. When the workpiece 10 rolls and pushes the rotating wheel 502, the rotating wheel 502 rotates with the workpiece 10, so that the flange 11 of the workpiece 10 slips relative to the rotating wheel 502, thereby avoiding the problem that the workpiece 10 accidentally flips over the rotating wheel 502. Therefore, when the workpiece 10 moves in the X direction, the flange 11 of the workpiece 10 can abut against the contact mechanism 500, and the contact mechanism 500 can push the whole sliding table 300 to move in the X direction. When the blocking mechanism 600 blocks the sliding table 300 to stop, the workpiece 10 also stops at this time.

[0057] Please refer to Figure 4 In an embodiment provided by the present application, the device further comprises a rotating shaft 700, a limiting mechanism 800 and a lifting mechanism 900. The rotating shaft 700 is rotatably installed on the sliding table 300. The limiting mechanism 800 and the lifting mechanism 900 are both installed on the rotating shaft 700 and rotate synchronously with the rotating shaft 700. The lifting mechanism 900 abuts against the contact mechanism 500. When the blocking mechanism 600 extends, the limiting mechanism 800 can abut against the blocking mechanism 600. The limiting mechanism 800 can rotate to raise the blocking wheel shaft, and the lifting mechanism 900 can rotate to lower.

[0058] In order to more stably stop the workpiece 10 in the process of moving, the limiting mechanism 800 is adopted in the embodiment. When the blocking mechanism 600 extends, the limiting mechanism 800 is contacted. The limiting mechanism 800 can extend above the standard surface 104 of the workbench 100 relative to the rotating wheel 502, so as to more stably block the workpiece 10 and avoid the problem that the workpiece 10 is separated due to sudden stop.

[0059] Please refer to Figure 5 When the limiting mechanism 800 is in the initial position, the lifting mechanism is in the state of abutting against the lifting shaft 501, so that the lifting shaft 501 is in the highest position. When the limiting mechanism 800 is contacted by the blocking mechanism 600, the limiting mechanism 800 moves in the clockwise direction, the rotating shaft 700 moves in the clockwise direction, and the lifting mechanism 900 moves in the clockwise direction. At this time, the overall height of the limiting mechanism 800 rises, and the height of the rotating wheel 502 decreases. The rotating wheel 502 is separated from the flange 11 of the workpiece 10, and the limiting mechanism 800 can block the flange 11 of the workpiece 10. The limiting mechanism 800 provides more stable blocking, thereby avoiding the problem that the workpiece 10 is separated due to the sudden blocking of the sliding table 300.

[0060] The limiting mechanism 800 comprises a blocking arm 801 fixed on the rotating shaft 700, a locking piece 802 capable of locking the blocking arm 801, and a trigger arm 803 connected with the locking piece 802; when the trigger arm 803 rotates, the locking of the blocking arm 801 by the locking piece 802 can be released. The reason why the position of the blocking arm 801 needs to be locked by the locking piece 802 in the initial state is to keep the position of the lifting mechanism 900, so that the lifting mechanism 900 can abut against the lifting shaft 501 in the initial state, and the lifting shaft 501 and the rotating wheel 502 are in the highest position.

[0061] As Figure 5 and Figure 6 The number of the trigger arms 803 is two, the two trigger arms 803 are fixedly connected, the blocking arm 801 is between the two trigger arms 803, one side of the trigger arm 803 is marked as a first stress side 8031, and one side of the blocking arm 801 is marked as a second stress side 8032. In the initial position, the first stress side 8031 of the trigger arm 803 is lower than the second stress side 8032 in position. In this way, when the blocking mechanism 600 is in the stretched state, the first stress side 8031 of the trigger arm 803 will be contacted first, the trigger arm 803 will be pushed to rotate, the trigger arm 803 will rotate relative to the locking piece 802, the locking of the blocking arm 801 by the locking piece 802 can be contacted, and the blocking arm 801 can also rotate.

[0062] When the trigger arm 803 is pushed to rotate by the blocking mechanism 600 to a certain angle, it will be completely retracted between the two trigger arms 803. At this time, the two trigger arms 803 contact the blocking mechanism 600 and rotate clockwise, and the lifting height is used to block the workpiece 10. Therefore, in the embodiment, the locking of the blocking arm 801 by the locking piece 802 is used to keep the rotating wheel 502 in the highest position to stably contact the flange 11 of the workpiece 10. When the trigger arm 803 is pressed, the locking piece 802 can be released. At this time, the position of the blocking arm 801 is raised, the position of the rotating wheel 502 is lowered, the blocking arm 801 is used to replace the rotating wheel 502 to block the workpiece 10, and the workpiece 10 is stopped.

[0063] Please refer to Figure 8The locking member 802 comprises a fixed ring 8021, a rotating ring 8023, a locking post 8025, a pulling body 8026, the fixed ring 8021 is fixed on the sliding table 300 and cannot rotate, and a locking hole 8022 is formed in the fixed ring 8021; the rotating ring 8023 is rotatably installed on the rotating shaft 700, and the rotating ring 8023 can be directly sleeved on the rotating shaft 700, an unlocking groove 8024 is formed in the rotating ring 8023, and the trigger arm 803 is fixed on the rotating ring 8023; the locking post 8025 is installed on the blocking arm 801, and the end of the locking post 8025 can be inserted into the locking hole 8022; the pulling body 8026 is installed on the locking post 8025 and located in the unlocking groove 8024, and when the rotating ring 8023 rotates, the pulling body 8026 can be driven to move and drive the locking post 8025 to disengage from the locking hole 8022, thereby releasing the locking of the blocking arm 801.

[0064] Please refer to Figure 9 The unlocking groove 8024 has a first inclined surface 8027, the pulling body 8026 has a second inclined surface 8028 which is in abutment with the first inclined surface 8027, when the trigger arm 803 is not pressed and is in the initial position, the first inclined surface 8027 and the second inclined surface 8028 are in abutment, when the trigger arm 803 rotates after contacting the blocking mechanism 600, the first inclined surface 8027 pushes the second inclined surface 8028, so that the pulling body 8026 moves away from the fixed ring 8021, at this time, the pulling body 8026 can pull the locking post 8025, so that the end of the locking post 8025 disengages from the inside of the locking hole 8022, at this time, the blocking arm 801 is unlocked, so that the blocking arm 801 can rotate.

[0065] In this embodiment, the locking post 8025 is slidably installed on the blocking arm 801, and a spring is further arranged between the locking post 8025 and the blocking arm 801, when the locking post 8025 moves away from the fixed ring 8021, the end of the locking post 8025 presses the spring, so that the spring is deformed, when the position of the locking post 8025 corresponds to the position of the locking hole 8022 again, the spring can push the locking post 8025 back to the inside of the locking hole 8022.

[0066] As shown in FIG. 9, the unlocking groove 8024 has a side groove 805 formed in the radial side wall of the rotating ring 8023 and an end groove 806 formed in the axial end of the rotating ring 8023, and the pulling body 8026 comprises an abutting portion 807 and an embedded portion 808, the abutting portion 807 is located in the side groove 805, the first inclined surface 8027 is located in the side groove 805, the second inclined surface 8028 is located in the abutting portion 807, the abutting portion 807 is used to drive the pulling body 8026 when the rotating ring 8023 rotates, and the embedded portion 808 is located in the through groove and abuts with the groove wall of the end groove 806, so that the pulling body 8026 and the locking post 8025 cannot rotate.

[0067] A reset structure 809 is arranged between the two blocking arms 801 to help reset the trigger arm 803. The reset structure 809 can be a spring or a structure made of silicone or rubber that can be deformed and has elasticity. When the trigger arm 803 is pushed by the blocking mechanism 600, the trigger arm 803 can press the reset structure 809. When the pressure on the trigger arm 803 disappears, the reset structure 809 can push the trigger arm 803 to extend out from between the two blocking arms 801 again.

[0068] Please refer to Figure 7 A rebound structure 804 is further arranged between the slide table 300 and the blocking arm 801. The rebound structure 804 can push the blocking arm 801 to rotate. The rebound structure 804 helps reset the blocking arm 801. One embodiment of the rebound structure 804 includes a base 8041 fixed on the slide table 300, an arc slot 8042 formed in the base 8041, an arc column 8043 inside the arc slot 8042, a pressing body 8044 fixed on the blocking arm 801 and slidingly sleeved outside the arc column 8043, and an arc spring 8045 sleeved outside the arc column 8043. When the blocking arm 801 is pressed to rotate by the blocking mechanism 600, the pressing body 8044 can be driven to rotate, which presses the arc spring 8045. When the blocking mechanism 600 is retracted and the blocking arm 801 is no longer pressed, the arc spring 8045 can push the pressing body 8044 to reset the blocking arm 801. Therefore, the arc slot 8042, the arc column 8043, and the arc spring 8045 and the rotating shaft 700 are concentric.

[0069] Therefore, in this embodiment, when the slide table 300 approaches the extended blocking mechanism 600, the trigger arm 803 first contacts the blocking mechanism 600, and the trigger arm 803 first rotates relative to the blocking arm 801 to drive the pulling body 8026, so that the locking column 8025 is disengaged from the fixed ring 8021, and the blocking arm 801 is unlocked.

[0070] Then, the blocking mechanism 600 can simultaneously push the trigger arm 803 and the blocking arm 801, so that the heights of the two are increased to block the workpiece 10, so that the workpiece 10 can be more stably stopped.

[0071] When the rust removal machine 200 removes the rust on the identification plate on the workpiece 10, the blocking mechanism 600 falls, at this time the blocking arm 801 cannot maintain the height, under the push of the workpiece 10, it rotates to lower the height, so that the workpiece 10 continues to move in the X direction until it is separated from the workbench 100, under the push of the rebound structure 804, the blocking arm 801 resets to the initial position, in the process, the rotating shaft 700 rotates synchronously, through the lifting mechanism 900, the lifting shaft 501 and the rotating wheel 502 are reset to the highest position, when the blocking arm 801 returns to the initial position, the end of the lock column 8025 resets to the inside of the lock hole 8022, and the blocking arm 801 is locked again.

[0072] Finally, it should be noted that the methods and devices described in detail above are only embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present application.
