Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Reference Figure 1 , Figure 2 and Figure 3, the utility model provides an embodiment: a positioning device for laser quenching and cladding machining, including a workbench 1, an L-shaped plate 4 is fixedly connected to the lower part of the workbench 1, a first motor 6 is arranged at the lower part of the L-shaped plate 4, an output end of the first motor 6 is fixedly connected to a rotating shaft 7, the rotating shaft 7, a gear 8 is fixedly connected to the outside of the rotating shaft 7, rack plates 9 are meshed and connected to the outside of the gear 8, guide rings 10 are fixedly connected to the outside of the two rack plates 9, mounting rods 12 are fixedly connected to the upper parts of the two rack plates 9, mounting frames 14 are fixedly connected to the top of the upper parts of the two mounting rods 12, and flip components are arranged on the outside of the two mounting frames 14, and two flip components The outside of the parts are fixedly connected with mounting plates 20, both sides of the outside of the mounting plates 20 are fixedly connected with limit rods 21, both sides of the inside of the mounting plates 20 are fixedly connected with electric push rods 23, the output ends of the two electric push rods 23 are fixedly connected with clamping plates 24, the inner walls of the two clamping plates 24 are provided with protective pads 25, the lower part of the L-shaped plate 4 is fixedly connected with a fixing plate 5, the first motor 6 is fixedly connected to the upper part of the fixing plate 5, both sides of the upper part of the L-shaped plate 4 are fixedly connected with guide rods 11, two guide rings 10 are slidably connected to the outside of the two guide rods 11, through holes 13 are opened on both sides of the upper part of the workbench 1, and two mounting rods 12 are slidably connected to the inside of the two through holes 13.
[0026] When in use, first place the workpiece to be fixed on the upper part of the workbench 1. Then, start the first motor 6, and the motor drives the gear 8 to rotate through the rotating shaft 7 fixedly connected to the output end. The rotation of the gear 8 further drives the rack plate 9 meshing with it to move relative to each other. Since the two rack plates 9 are arranged relative to each other, their movement will drive the two mounting rods 12 and the mounting frame 14 to move relative to each other. In this way, the two mounting plates 20 will be adjusted accordingly according to the length of the workpiece until they are in close contact with both ends of the workpiece. At this time, start the two electric push rods 23. The electric push rod 23 pushes the two protective pads 25 toward the workpiece through the clamping plate 24 fixedly connected to the output end. The setting of the protective pad 25 is intended to protect the surface of the workpiece and prevent scratches or damage during the fixing process. When the two protective pads 25 are tightly fitted to the outside of the workpiece, the entire fixing process is completed, which makes it easy to fix workpieces of different lengths. It can be adjusted according to the length of the workpiece to clamp workpieces of different diameters and lengths, thereby improving the applicability of the device and reducing production costs. The fixing plate 5 is arranged to facilitate the fixing of the first motor 6, which is slidably connected to the outside of the two guide rods 11 through two guide rings 10, thereby playing a guiding role.
[0027] Reference Figure 2 and Figure 4The flip assembly includes a second motor 16, which is arranged outside the two mounting frames 14. A worm 17 is fixedly connected to the output end of the second motor 16. A worm wheel 18 is meshedly connected to the lower part of the worm 17. A rotating rod 19 is fixedly connected inside the worm wheel 18. The rotating rod 19 is rotatably connected inside the mounting frame 14. A mounting plate 20 is fixedly connected outside the rotating rod 19. An annular groove 22 is opened inside the mounting frame 14. Two limit rods 21 are slidably connected inside the annular groove 22. A horizontal plate 15 is fixedly connected to the outside of the mounting frame 14. The second motor 16 is fixedly connected to the upper part of the horizontal plate 15.
[0028] When the workpiece needs to be turned over, the two second motors 16 are started synchronously, and the two motors drive the two worms 17 fixedly connected at the output end to start rotating. The rotation of the worm 17 then drives the two worm wheels 18 meshingly connected at the lower part to rotate. This transmission method ensures the smooth and accurate rotation. Next, the rotation of the worm wheel 18 drives the two rotating rods 19 fixedly connected inside to rotate. The rotation of the rotating rod 19 is through the two mounting plates 20 fixedly connected outside, and finally the turning of the workpiece is realized, which makes it easy to turn the workpiece according to the requirements of laser quenching or cladding processing. By turning the workpiece, the surface of the workpiece can be uniformly treated. During the quenching or cladding process, the energy distribution of the laser beam may be uneven, resulting in higher thermal impact on some areas of the workpiece surface, while other areas are less affected by heat. By turning the workpiece over, different parts can be treated more evenly, thereby improving the consistency of processing quality and performance. By setting the cross plate 15, it is convenient to fix the second motor 16, and two limit rods 21 are slidably connected inside the annular groove 22 to play a limiting role.
[0029] Reference Figure 1 A controller 2 is installed on the upper right side of the workbench 1, and the controller 2 is electrically connected to the first motor 6 and the second motor 16. A base plate 3 is fixedly connected to the outer rear side of the workbench 1, and a fixing frame 26 is fixedly connected to the upper part of the base plate 3. A robotic arm 27 is installed on the upper part of the fixing frame 26, and a laser cladding gun 28 is installed on the other end of the robotic arm 27.
[0030] When quenching or cladding the workpiece, the robot arm 27 and the laser cladding gun 28 cooperate to automatically quench or clad the workpiece. The controller 2 is provided to facilitate the control of the opening and closing of the first motor 6 and the second motor 16.
[0031] Working principle: when it is necessary to fix workpieces of different lengths, first place the workpiece on the upper part of the workbench 1, and then start the first motor 6, the first motor 6 rotates the rotating shaft 7 fixedly connected to the output end, the rotating shaft 7 rotates and the gear 8 fixedly connected to the outside rotates, the gear 8 rotates and the rack plates 9 meshing on both sides of the outside move relatively, the two rack plates 9 move relatively and the two mounting rods 12 fixedly connected to the upper part move relatively, the two mounting rods 12 move relatively and the mounting frames 14 fixedly connected to the top move relatively, the two mounting frames 14 move relatively and the two mounting plates 20 fixedly installed on the outside move relatively, so that the two mounting plates 20 contact the two ends of the workpiece, and then start the two electric push rods 23, the two electric push rods 23 move the two clamping plates 24 fixedly connected to the output end, the two clamping plates 24 move and the two protective pads 25 arranged on the inner wall move relatively. Move the two protective pads 25 to fit the outside of the workpiece, so that it is convenient to fix workpieces of different lengths. It can be adjusted according to the length of the workpiece, so as to clamp workpieces of different diameters and lengths, improve the applicability of the device, and reduce production costs. Then, when the workpiece needs to be flipped, the two second motors 16 are started synchronously, and the two second motors 16 rotate with the two worms 17 fixedly connected at the output end, and the two worms 17 rotate with the two worm wheels 18 meshingly connected at the bottom, and the two worm wheels 18 rotate with the two rotating rods 19 fixedly connected inside, and the two rotating rods 19 rotate with the two mounting plates 20 fixedly connected outside, and the two mounting plates 20 rotate with the workpiece fixedly connected inside, so that it is convenient to flip the workpiece according to the requirements of laser quenching or cladding processing. By flipping the workpiece, the surface of the workpiece can be uniformly treated. During the quenching or cladding process, the energy distribution of the laser beam may be uneven, resulting in higher thermal impact on some areas of the workpiece surface, while other areas are less thermally affected. By flipping the workpiece, different parts can be treated more evenly, thereby improving the consistency of processing quality and performance.
