Abstract
Description
Technical Field
[0001] This utility model relates to the field of laser processing equipment, and in particular to a laser quenching device for shaft processing in power plants. Background Technology
[0002] Bearing rings are a type of shaft component in power plants. They are ring-shaped parts of radial rolling bearings with one or more raceways, typically consisting of an outer ring and an inner ring. In power plants, bearing rings are primarily used to support rotating shafts, such as the main shaft of a generator and the rotor of a turbine, ensuring their smooth rotation.
[0003] Existing laser hardening equipment typically processes the inner and outer walls of bearings separately. For large-sized shaft parts used in power plants, this processing method is time-consuming and inefficient. Therefore, we propose an improved laser hardening equipment for power plant shaft processing. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a laser quenching device for shaft processing in power plants.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a laser quenching device for shaft processing in power plants, comprising a worktable, a bearing ring provided on the worktable, a support frame fixedly connected to the upper end face of the worktable, and an adjusting screw one and an adjusting screw two rotatably connected to the lower end face of the support frame, with a slider threadedly connected to the outer wall of both adjusting screw one and adjusting screw two, an electric cylinder fixedly connected to each of the two sliders, and a laser processing head fixedly connected to the output end of each of the two electric cylinders.
[0006] Through the above technical solution, the two laser processing heads of the device can adjust their positions according to the size of the bearing ring, and simultaneously perform quenching processing on the inner and outer walls of the bearing ring, thereby improving processing efficiency.
[0007] As a further description of the above technical solution:
[0008] One end of the adjusting screw is fixedly connected to a slide rod, and one end of the adjusting screw is fixedly connected to a slide rod. The other ends of the two sliders are respectively slidably sleeved on the outer walls of the slide rods.
[0009] Through the above technical solution, adjusting screw one and adjusting screw two are used to drive the slider to move, and sliding rod one and sliding rod two are used to limit the movement of the slider.
[0010] As a further description of the above technical solution:
[0011] Servo motors are fixedly connected to both outer walls of the support frame, and the output ends of the two servo motors are fixedly connected to one end of the adjusting screw one and the adjusting screw two, respectively.
[0012] Through the above technical solution, the two servo motors can drive the first adjusting screw and the second adjusting screw to rotate respectively.
[0013] As a further description of the above technical solution:
[0014] The two laser processing heads are respectively positioned on the inner and outer sides of the bearing ring, and the maximum lifting height of the two laser processing heads is greater than the height of the bearing ring.
[0015] The above technical solution facilitates the loading and unloading of bearing rings and avoids the laser processing head obstructing the loading and unloading of bearing rings.
[0016] As a further description of the above technical solution:
[0017] A drive screw is rotatably connected to the worktable. Mounting blocks are threaded onto the front and rear outer walls of the drive screw. Rubber wheels are rotatably connected to both mounting blocks, and both rubber wheels are rotatably disposed inside the bearing ring.
[0018] The above technical solution controls the relative movement of two mounting blocks by rotating the drive screw, thereby causing the two rubber wheels to abut against the inner ring of the bearing race. This facilitates the rotation of the bearing race by the rotating rubber wheels, making it easier for the laser processing head to perform laser quenching processing on it.
[0019] As a further description of the above technical solution:
[0020] One of the mounting blocks is fixedly connected to a drive motor, and the output end of the drive motor is fixedly connected to the upper end of the shaft of the fixed sleeve rubber wheel.
[0021] Through the above technical solution, the drive motor can drive the rubber wheel to rotate.
[0022] This utility model has the following beneficial effects:
[0023] 1. Compared with existing technologies, this laser quenching device for shaft processing in power plants, through the coordinated arrangement of a support frame, adjusting screw one, slide one, adjusting screw two, slide two, slider, electric cylinder, and laser processing head, can control the movement of two sliders by rotating adjusting screw one and adjusting screw two respectively. This allows the two laser processing heads to adjust their positions according to the size of the bearing ring and simultaneously perform quenching processing on the inner and outer walls of the bearing ring, thereby improving processing efficiency.
[0024] 2. Compared with existing technologies, this laser quenching device for shaft processing in power plants, by setting up a drive screw, mounting block, rubber wheels and drive motor structure, enables the device to be adapted to drive various bearing rings of different specifications by adjusting the distance between the two rubber wheels, thus making it more versatile.

[0031] Reference Figure 1-4 The present invention provides a laser quenching device for shaft processing in power plants, comprising a worktable 1, a bearing ring 2 on the worktable 1, a support frame 7 fixedly connected to the upper end face of the worktable 1, and an adjusting screw 10 and an adjusting screw 2 rotatably connected to the lower end face of the support frame 7, respectively. Slider 12 is threadedly connected to the outer wall of both adjusting screw 10 and adjusting screw 2 10. By rotating adjusting screw 10 and adjusting screw 2 10, the slider 12 is moved, thereby adjusting the horizontal position of the laser processing head 14. Electric cylinders 13 are fixedly connected to both sliders 12, and the output ends of both electric cylinders 13 are fixedly connected to the laser processing head 14. The action of the electric cylinders 13 controls the lifting and lowering adjustment of the laser processing head 14.
[0032] Through the above technical solution, the two laser processing heads 14 of the device can adjust their positions according to the size of the bearing ring 2, and simultaneously perform quenching processing on the inner and outer walls of the bearing ring 2, thereby improving processing efficiency.
[0033] One end of the adjusting screw 8 is fixedly connected to the slide rod 9, and one end of the adjusting screw 10 is fixedly connected to the slide rod 11. The other ends of the two sliders 12 are respectively slidably sleeved on the outer walls of the slide rod 9 and the slide rod 11. The adjusting screw 8 and the adjusting screw 10 are used to drive the sliders 12 to move, and the slide rods 9 and 11 are used to limit the movement of the sliders 12.
[0034] Servo motors 15 are fixedly connected to the outer walls on both sides of the support frame 7. The output ends of the two servo motors 15 are fixedly connected to one end of the adjusting screw 8 and the adjusting screw 10, respectively. The two servo motors 15 can drive the adjusting screw 8 and the adjusting screw 10 to rotate, respectively.
[0035] Two laser processing heads 14 are respectively positioned on the inner and outer sides of the bearing ring 2, and the maximum lifting height of the two laser processing heads 14 is greater than the height of the bearing ring 2, which facilitates the loading and unloading of the bearing ring 2 and avoids the laser processing heads 14 obstructing the loading and unloading of the bearing ring 2.
[0036] A drive screw 3 is rotatably connected to the worktable 1. Mounting blocks 4 are threadedly connected to the front and rear outer walls of the drive screw 3. Rubber wheels 5 are rotatably connected to the two mounting blocks 4. The two rubber wheels 5 are rotatably set inside the bearing ring 2. By rotating the drive screw 3, the relative movement of the two mounting blocks 4 is controlled, so that the two rubber wheels 5 abut against the inner ring of the bearing ring 2. This makes it convenient for the rubber wheels 5 to rotate and drive the bearing ring 2 to rotate, which is convenient for the laser processing head 14 to perform laser quenching processing on it.
[0037] One of the mounting blocks 4 is fixedly connected to a drive motor 6. The output end of the drive motor 6 is fixedly connected to the upper end of the rotating shaft of the fixed sleeve rubber wheel 5. The drive motor 6 can drive the rubber wheel 5 to rotate.
[0038] Working principle: The bearing ring 2 is placed on the worktable 1. Then, the drive screw 3 is rotated by the rotating wheel, which in turn controls the relative movement of the two mounting blocks 4, thereby driving the relative movement of the two rubber wheels 5, which press against the inner walls of the two sides of the bearing ring 2. This allows the device to process bearing rings 2 of different sizes. Then, the two servo motors 15 are started to control the rotation of the adjusting screw 1 8 and the adjusting screw 2 10, which in turn drives the two sliders 12 to move, so as to adjust the relative position of the two laser processing heads 14 with respect to the inner and outer walls of the bearing ring 2. Then, the drive motor 6 is started to drive one of the rubber wheels 5 to rotate, which in turn drives the bearing ring 2 to rotate with respect to the laser processing head 14. Then, the two laser processing heads 14 process the outer and inner walls of the bearing ring 2 simultaneously, thereby effectively improving the processing efficiency.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
