Description

Technical Field

[0001] The utility model belongs to the technical field of bearing induction heat treatment, and particularly relates to an anti-collision supporting device for a large-scale wind power bearing non-soft zone quenching inductor. Background Technique

[0002] The wind power main shaft bearing is an important component of a wind turbine generator, and has high strength requirements. Therefore, the wind power main shaft bearing needs to be quenched. With the booming development of the wind power industry, non-soft zone quenching of large-megawatt wind turbine main bearings has become a new trend. The traditional scanning type induction heating quenching has low production efficiency. Therefore, a workpiece rotation type induction heating integral quenching equipment has been developed. Multiple large-scale inductors are heated simultaneously, and the heating time is shortened by more than 70% compared with the traditional scanning type heating time.

[0003] However, it is found in the production process that because the inductor selected by this induction heating quenching equipment is relatively large, the inductor is attracted by the workpiece due to the action of the alternating magnetic field during heating. The connection part between the inductor and the transformer may even be deformed due to the action of a strong magnetic moment. The inductor will approach the surface of the workpiece, and there is a risk of touching the workpiece. Once the workpiece is touched, it is very likely to cause the equipment to stop due to arcing, and even cause serious accidents such as inductor damage or workpiece scrapping, affecting production efficiency and production cost. Summary of the Invention

Specific Embodiments

[0019] The following further elaborates on the specific embodiments of the present utility model in conjunction with the attached drawings.

[0020] Such as Figures 1-3As shown in the figure, an anti-collision support device for a large wind power bearing non-soft-zone quenching inductor includes an inductor 3 and inductor frame side plates 4 on both sides thereof. The anti-collision support device is installed on the inductor frame side plates 4 through a mounting base 7. A cylinder 8 is provided on the left side of the anti-collision support device. The cylinder 8 is fixed on the mounting base 7 through cylinder base mounting holes 17 provided at four corners. A piston rod 9 capable of linear telescopic movement is provided in the cylinder 8. The protruding end of the piston rod 9 is threadedly connected to one end of a connecting rod 11. The other end of the connecting rod 11 is threadedly connected to one end of an adjusting screw 12. An adjusting nut 13 is sleeved on the adjusting screw 12. The other end of the adjusting screw 12 is fixedly provided with a screw fork head 15. A bearing 16 is installed in the screw fork head 15. The outer ring of the bearing 16 extends beyond the outer edge position of the screw fork head 15. The left part of the connecting rod 11 is slidably installed in a guiding device 10.

[0021] A circular mounting hole is provided at the lower left corner position of the inductor frame side plate 4, and a long arc mounting hole 6 is provided at the upper right position corresponding to the circular mounting hole; both ends of the mounting base 7 of the anti-collision support device are provided with circular mounting holes distributed in an equilateral triangle, and are adapted to the positions and dimensions of the circular mounting hole and the long arc mounting hole on the inductor frame side plate 4. Through the circular mounting hole and the long arc mounting hole 6 on the inductor frame side plate 4, it is convenient to adjust the mounting angle of the anti-collision support device, and synchronously adjust the direction of the anti-collision support device along with the heating position of the inductor copper tube 5, ensuring that the telescopic movement direction of the device is perpendicular to the induction heating surface of the workpiece 2, effectively preventing the risk of collision and contact between the inductor copper tube 5 and the workpiece 2, and improving the operation stability of the quenching induction equipment.

[0022] The base of the guiding device 10 is a square plate-like structure, and mounting holes are provided at four corners. The guiding device 10 is fixedly installed on the mounting base 7, and a square tube is fixedly provided on the base of the guiding device 10.

[0023] The connecting rod 11 is a square rod-like structure. The left part of the connecting rod 11 is slidably inserted into the square tube of the guiding device 10. The inner diameter dimension of the square tube is adapted to the outer diameter dimension of the connecting rod 11, preventing the connecting rod 11 from deflecting, and ensuring that the contact line between the bearing 16 and the workpiece 2 is always perpendicular to the rotary motion direction of the workpiece 2 when contact occurs. A threaded hole 14 is provided inside the right part of the connecting rod 11. The left end of the adjusting screw 12 is threadedly connected to the threaded hole inside the right part of the connecting rod 11. The left external thread of the adjusting screw 12 is adapted to the right internal thread of the connecting rod 11.

[0024] The cylinder 8 is automatically controlled by a PLC through a solenoid valve. The telescopic movement direction of the anti-collision support device is perpendicular to the induction heating surface of the workpiece 2.

[0025] Each component of the anti-collision support device is made of a non-magnetic material such as stainless steel, aluminum alloy or copper; the bearing 16 is a high-temperature resistant bearing.

[0026] During use, the wind power main bearing workpiece 2 to be quenched is placed on the driving and positioning device of the lifting platform 1. After the workpiece 2 rotates and is automatically aligned, the positioning device is locked. The program controls the robotic arm to drive the multi-head inductor 3 to the set heating position. Then the driving device drives the workpiece 2 to rotate. When the rotational speed reaches the required value, heating starts. When the temperature reaches the required value, heating stops. The robotic arm drives the inductor 3 to quickly retract, and at the same time the lifting device quickly descends into the quenching tank for cooling. The robotic arm drives the inductor 3 back to the initial position. After the cooling is completed, the workpiece 2 stops rotating, and the quenching treatment of the workpiece 2 is completed. The lifting platform 1 rises.

[0027] An anti-collision support device is installed on the side plate of the inductor frame 4. When the inductor 3 is in a non-working state, the cylinder 8 is in a retracted state. When the inductor 3 and the workpiece 2 are adjusted to a suitable position, the cylinder 8 extends. The adjusting screw 12 is adjusted to keep the end of the bearing 16 of the anti-collision support device protruding about 2-3 mm from the inductor copper tube 5, that is, less than the set working interval distance between the inductor 3 and the workpiece 2. During the heating process, once the inductor 3 is attracted and approaches the workpiece 2 beyond a certain safe working distance, the anti-collision support device comes into play to prevent the inductor 3 from touching the workpiece 2. By installing the anti-collision support device for the inductor 3, an infinite approach between the inductor 3 and the large wind power bearing workpiece 2 to be quenched and heated is restricted by a fixed and reliable mechanical device, ensuring a certain safety distance, preventing collisions between the inductor and the workpiece 2, effectively avoiding equipment and quality accidents such as shutdown caused by the inductor 3 touching the workpiece 2, damage to the inductor 3 or scrapping of the workpiece 2, improving the utilization rate and production efficiency of the large wind power bearing quenching induction equipment, and reducing production costs.

[0028] In addition to the above embodiments, the present utility model can also have other implementation manners. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the protection scope required by the present utility model.
