Description

Technical Field

[0001] The present invention relates to the technical field of laser cladding, and particularly to a servo control system of an alternating current permanent magnet linear synchronous motor for laser cladding. Background Art

[0002] Laser Cladding, also known as Laser Deposition or Laser Coating, is a new surface modification technology. It forms a metallurgical bonded filler cladding layer on the surface of the substrate by adding a cladding material on the surface of the substrate and melting it together with a thin layer of the substrate surface using a high-energy density laser beam. When performing laser cladding with a laser cladding machine, the movement trajectory and speed of the laser head are mainly precisely controlled by a linear synchronous motor servo control system to ensure the uniformity and quality of the cladding layer. Among linear synchronous motors, alternating current permanent magnet linear synchronous motors are more commonly used. Alternating current permanent magnet linear synchronous motors have the characteristics of simple structure, reliable operation, high efficiency, high precision, and high stability.

[0003] In the prior art, the servo control system of the alternating current permanent magnet linear synchronous motor for laser cladding generates a large amount of working heat during use, and the heat generation is significant. The permanent magnet of the linear motor is a high-heat-generating component, and its installation position is not conducive to natural heat dissipation, posing a great challenge to the constant temperature control of the laser cladding machine. In addition, most linear synchronous motors do not have a self-locking function. To ensure operation safety, the moving axis driven by the linear motor, especially the vertical moving axis, must be equipped with an additional locking mechanism, increasing the complexity of the laser cladding machine.

[0004] In view of the above technical problems, the present invention discloses a servo control system of an alternating current permanent magnet linear synchronous motor for laser cladding. The present invention has the advantages of automatic heat dissipation and timely heat removal, as well as a self-locking function. Summary of the Invention

Detailed implementation manners

[0018] The following is a detailed description of the embodiments of the present invention. These embodiments are implemented on the premise of the technical solution of the present invention, and detailed implementation manners and specific operation processes are given. However, the protection scope of the present invention is not limited to the following embodiments. In the description of the present invention, terms indicating orientation or positional relationships such as "front", "rear", "left", and "right" are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0019] The embodiment discloses a servo control system for an AC permanent magnet linear synchronous motor for laser cladding, including a workbench 1. A plurality of placement grooves 2 are equidistantly arranged at the inner bottom end of the workbench 1. A heat dissipation hole 3 communicating with the inner cavity of the workbench 1 is opened on the inner bottom wall of each placement groove 2. A placement plate 4 is arranged at the inner bottom end of the placement groove 2. A stator 5 is arranged on the top of the placement plate 4. The stator 5 is made of a magnetic steel (not shown in the prior art), and the magnetic poles between two adjacent stators 5 are opposite ("N" pole and "S" pole). An electric motor 6 is fixedly arranged in the inner cavity of the workbench 1. The electric motor 6 is fixedly connected with a threaded rod 7 through its output end. The threaded rod 7 is threadedly connected with a plurality of threaded blocks 8. A heat dissipation fan 9 is fixedly connected to the top of each threaded block 8. A guide block 10 is fixedly connected to the bottom of the threaded block 8. The guide block 10 is slidably connected with a guide rod 11. A first guide wheel 12 adapted to the inner bottom wall of the workbench 1 is fixedly connected to the bottom of the guide block 10. Disassembly openings 13 are opened on the outer walls of both sides of the inner cavity of the workbench 1. A disassembly cover 14 is arranged on the disassembly opening 13. Specifically, when implemented, the electric motor 6 is started to control it to drive the threaded rod 7 to rotate. The threaded block 8 threadedly connected with the threaded rod 7 moves horizontally along the central axis direction of the threaded rod 7, and then drives the heat dissipation fan 9 on the threaded block 8 to move horizontally back and forth (by the forward and reverse rotation of the electric motor 6). At the same time, when the threaded block 8 moves, the guide block 10 below it slides along the guide rod 11 and the first guide wheel 12 rolls to provide guiding and sliding for the threaded block 8. The heat dissipation fan 9 itself starts to work to generate gas, and the gas is blown onto the surface of the stator 5 on the placement plate 4 in each placement groove 2 in turn through the heat dissipation hole 3 as it moves, so as to perform heat dissipation work on it. In summary, it can be seen that through the settings of the electric motor 6, the threaded rod 7, the threaded block 8, and the heat dissipation fan 9, etc. in the present invention, after the device itself works for a period of time, the heat on the surface of the stator 5 can be dissipated by itself, avoiding the high temperature on the surface of the stator 5 from affecting its normal working state, ensuring that the stator 5 always works at a constant temperature, guaranteeing the normal operation of the device itself and improving the heat dissipation efficiency of the device itself; As Figures 1 - 8As shown in the figure, in this embodiment, a rotor 15 is arranged at the inner axis of the workbench 1. An electromagnet (not shown in the prior art) is arranged inside the rotor 15. By energizing the electromagnet and cooperating with the stator 5, a magnetic attraction reaction occurs, thereby driving the rotor 15 to slide horizontally. A supporting plate 16 is arranged at the top of the rotor 15. Through the supporting plate 16, the materials required for laser cladding can be placed on the plate. First sliders 17 are fixedly connected to both sides of the supporting plate 16. A sliding hole 18 is formed inside the first slider 17. A self-locking rod 19 is threadedly connected to the top inner cavity of the sliding hole 18. A self-locking head 20 is fixedly connected to the bottom of the self-locking rod 19 and a control handle 21 is fixedly connected to its top. A sliding rod 22 is slidably connected to the sliding hole 18. The sliding rod 22 is arranged on the front and rear sides of the top of the workbench 1. Self-locking holes 23 for the self-locking head 20 to be inserted are equidistantly arranged on the sliding rod 22. During specific implementation, by energizing the rotor 15, a reaction occurs between the rotor 15 and the stator 5, causing the rotor 15 to drive the materials on the supporting plate 16 to slide horizontally along the sliding rod 22 through the first sliders 17, and then moving the materials on the supporting plate 16 to the relative position for subsequent laser cladding operation. When locking is required in case of special working conditions during the material conveying process, the self-locking rod 19 is rotated through the control handle 21. As the self-locking rod 19 rotates, it gradually sinks and inserts the self-locking head 20 into the sliding hole 18 of the sliding rod 22 to achieve self-locking. To sum up, through the settings of the self-locking rod 19, self-locking head 20, sliding rod 22, and self-locking holes 23 of the present invention, the self-locking of the device can be realized according to needs when the device performs linear motion, and the positioning of the device during linear sliding can be controlled according to needs, so that the supporting plate 16 on the device and the products carried on the plate are transported to the corresponding positions, improving the working efficiency and application range of the device itself and realizing the self-locking function of the device.

[0020] As a preferred solution of the present invention, preferably, as Figure 6 shown, a plurality of first cleaning brushes 24 in contact with the outer wall of the sliding rod 22 are annularly arranged on the hole wall of the sliding hole 18. A second slider 25 is fixedly connected to the bottom of the first slider 17. A sliding cavity is formed in the second slider 25. Second guide wheels 26 are symmetrically arranged on the inner side wall of the sliding cavity. A third slider 27 adapted to the second guide wheels 26 is slidably connected to the sliding cavity. The third slider 27 is arranged on the workbench 1 and is located below the sliding rod 22. During specific implementation, as the rotor 15 moves, the first slider 17 slides synchronously along the sliding rod 22. At this time, the first cleaning brushes 24 arranged on the hole wall of the sliding hole 18 opened in the first slider 17 wipe the surface of the sliding rod 22 through relative movement, thereby timely cleaning the dust on the surface of the sliding hole 18. In addition, as the first slider 17 slides, the third slider 27 slides in the inner cavity of the second slider 25 and slides relative to the second guide wheels 26 in its inner cavity, further improving the guiding effect on the movement of the rotor 15.

[0021] As a preferred solution of the present invention, preferably, as Figure 9As shown in the figure, a rectangular rubber strip 28 is attached to the inner wall of the placement groove 2. A number of rubber pads 29 that come into contact with the stator 5 are equidistantly arranged on the inner wall of the rubber strip 28. Before placing the stator 5 in the placement groove 2, first slip the rectangular rubber strip 28 over the inner wall of the placement groove 2, and then place the stator 5 in the placement groove 2 to make its installation in the groove more stable and also achieve an anti-slip effect.

[0022] As a preferred embodiment of the present invention, preferably, as Figure 2 shown, a number of second cleaning brushes 30 that come into contact with the stator 5 are equidistantly arranged at the bottom end of the rotor 15. Rotating shafts 31 are rotatably arranged on both sides of the rotor 15. The rotating shafts 31 are fixedly connected to driving gears 32. Driven toothed plates 33 are fixedly arranged on both sides of the inner cavity of the workbench 1. Rack teeth 34 that are meshed with the driving gears 32 are equidistantly arranged at the top of the driven toothed plates 33. During specific implementation, as the rotor 15 slides horizontally, it drives the rotating shafts 31 to rotate. The rotation of the rotating shafts 31 controls the synchronous rotation of the driving gears 32. The driving gears 32 are meshed with the rack teeth 34 on the driven toothed plates 33. At the same time, the second cleaning brushes 30 at the bottom end of the rotor 15 move synchronously with them, wiping and cleaning the dust on the top surface of each stator 5 as they pass by.

[0023] As a preferred embodiment of the present invention, preferably, as Figure 12 shown, protective springs 35 are arranged on both sides of the top of the workbench 1. The protective springs 35 are elastically connected to a protective plate 36. A number of protective pads 37 are equidistantly arranged on the plate surface of the protective plate 36. To prevent the rotor 15 from moving a large distance horizontally and causing the supporting plate 16 on the rotor 15 to directly impact the inner wall of the workbench 1, the elastic expansion and contraction of the protective springs 35 drive the protective plate 36 and the protective pads 37 to expand and contract back and forth, providing a protective effect on the supporting plate 16 and restricting its movement distance. Additionally, even if the supporting plate 16 hits the protective plate 36 and the protective pads 37, the protective springs 35 buffer the impact to avoid the supporting plate 16 directly impacting the workbench 1 and causing damage, slowing down the movement speed of the supporting plate 16 and improving its safety performance during use.

[0024] As a preferred embodiment of the present invention, preferably, as Figure 1 、 Figure 8As shown in the figure, an indicating needle 38 is fixedly arranged on the outer side of the first slider 17 on one side of the supporting plate 16. A scale line 39 is arranged on the outer wall of the workbench 1 on the same side as the indicating needle 38. As the rotor 15 moves, the indicating needle 38 moves synchronously with it. And by the stop of the indicating needle 38 on the scale line 39, the movement mileage of the rotor 15 can be judged, which is convenient for the staff to make subsequent judgments and analysis. A drag chain 40 is fixedly arranged on the outer side of the first slider 17 on the other side of the supporting plate 16. A power transmission line (not shown in the prior art) is sleeved in the drag chain 40. A backing plate 41 is arranged on the outer wall of the workbench 1 on the same side as the drag chain 40. An electric control box 42 connected to the drag chain 40 is arranged on the backing plate 41. By turning on the electric control box 42 on the backing plate 41, power is transmitted to the electromagnet in the rotor 15 through the power transmission line on the drag chain 40, so as to drive the overall movement of the supporting plate 16. When the above work is carried out, the drag chain 40 unfolds synchronously randomly.

[0025] As a preferred embodiment of the present invention, preferably, as Figure 11 shown in the figure, sliding columns 43 are arranged at the four corners of the bottom of the workbench 1. A buffer cylinder 44 is arranged below the sliding columns 43. A sliding hole 45 slidably connected to the sliding columns 43 is arranged at the top center of the buffer cylinder 44. A first sliding plate 46 and a second sliding plate 47 are slidably arranged in the inner cavity of the buffer cylinder 44 from high to low in sequence. The middle of the top of the first sliding plate 46 is fixedly connected to a buffer column. A first buffer spring 48 is elastically arranged between the first sliding plate 46 and the second sliding plate 47. Buffer balls 49 are symmetrically arranged on both sides of the top of the first sliding plate 46. Second buffer springs 50 elastically connected to the inner bottom wall of the buffer cylinder 44 are arranged at equal intervals at the bottom of the second sliding plate 47. The bottom of the buffer cylinder 44 is fixedly connected to a work base 51. During specific implementation, when the system on the workbench 1 is working, a certain degree of vibration load will be generated accordingly. At this time, the sliding columns 43 slide down along the sliding holes 45 into the buffer cylinder 44. At the same time, the sliding columns 43 will squeeze the first buffer spring 48 and the second buffer springs 50. The buffer balls 49 made of rubber material also expand. Then, the first buffer spring 48 and the second buffer springs 50 control their stretching and resetting by their own elastic potential energy, and the buffer balls 49 are in a compressed state. Through the stretching and shrinking of each spring and the buffer balls 49, the vibration load generated by the system work can be buffered and eliminated, further reducing the influence of vibration on the work of the system itself and improving its anti-vibration effect.

[0026] As a preferred embodiment of the present invention, preferably, as Figure 12As shown in the figure, assembly plates 52 are symmetrically arranged on both sides of the working base 51. Reinforcing ribs 53 are equidistantly arranged between the assembly plates 52 and the working base 51. A number of assembly holes 54 are equidistantly arranged on the plate surface of the assembly plates 52. An assembly bolt 55 is inserted into each assembly hole 54. An assembly gasket 56 is arranged in a fitting manner between the assembly bolt 55 and the plate surface of the assembly plate 52. During specific implementation, the assembly bolt 55 is successively driven into the corresponding assembly hole 54, and then the assembly plate 52, the working base 51 and the workbench 1 are fixedly installed by positioning the assembly bolt 55 at the installation point. Among them, the assembly hole 54 is threadedly connected to the assembly bolt 55 itself. The arrangement of the assembly plate 52 serves as an assembly platform to facilitate the installation of the working base plate. In addition, the arrangement of the reinforcing ribs 53 can improve the connection stability and structural strength between the assembly plate 52 and the working base 51.

[0027] The principle of the present invention is as follows: As Figures 1 - 13As shown, the present invention first drives the corresponding assembly bolts 55 into the corresponding assembly holes 54 in sequence, and realizes the fixed installation of itself and the system at the installation point through the assembly plate 52. Then, the materials required for the laser cladding work are placed on the supporting plate 16, and the electric control box 42 is turned on. The electric control box 42 energizes the electromagnet in the rotor 15 through the power transmission lines contained in the drag chain 40. The energized electromagnet magnetically reacts with the stator 5 in the placement groove 2 on the workbench 1, thereby controlling the rotor 15 to drive the supporting plate 16 and the materials to slide horizontally along the central axis direction of the slide rod 22, so as to carry out the subsequent laser cladding work at the required positions for material transportation. The movement of the rotor 15 is mainly carried out by the first slider 17 sliding along the slide hole 18 on the slide rod 22, and the second slider 25 slides on the third slider 27 to assist in the guiding work. When it is necessary to position the supporting plate 16 when the first slider 17 slides on the slide rod 22, the control handle 21 is used to drive the self-locking rod 19 to rotate, so that the self-locking head 20 connected to the self-locking rod 19 is inserted into the self-locking hole 23 of the slide rod 22 to achieve self-locking. During the movement of the rotor 15, the second cleaning brush 30 is controlled to wipe the surfaces of the stator 5 through the meshing transmission between the driving gear 32 and the driven toothed plate 33 and the rack 34, so as to prevent it from being dusty. And the movement of the rotor 15 is restricted by the elastic expansion and contraction of the protection spring 35 to control the protection plate 36 and the protection pad 37, so as to prevent it from directly colliding with the workbench 1 due to excessive movement distance. In addition, the vertical sliding of the sliding column 43 in the buffer cylinder 44 buffers and dampens the work on the workbench 1. During the movement of the rotor 15, the motor 6 is turned on to drive the threaded rod 7 to rotate. Under the guiding action of the first guide wheel 12 and the guide block 10 sliding along the guide rod 11, the threaded block 8 drives the heat dissipation fan 9 connected above it to move horizontally along the central axis of the threaded rod 7. At the same time, the heat dissipation fan 9 is synchronously turned on to blow the gas generated by the work to the surface of the stator 5 along the heat dissipation holes 3, so that the surface of the stator 5 is quickly cooled, avoiding the high surface temperature of the stator 5 from affecting its normal working state, ensuring that the stator 5 always works at a constant temperature. Moreover, the disassembly cover 14 on the disassembly port 13 is regularly removed to maintain the components such as the motor 6 and the threaded rod 7 in the working chamber and dissipate the heat of the working chamber in time.

Therefore, in any aspect, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description.
