[0027] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] like Figures 1-5 As shown, this specific embodiment adopts the following technical solution: It includes a water tank 1, a water pump 2, a delivery pipe 3, and a controller 4.

The filter plate 21 can filter out impurities such as metal fragments in the cooling waste liquid, so as to avoid the pipe blockage caused by too many impurities such as metal fragments during the discharge of the cooling waste liquid.

[0029] It also includes:

[0030] A splash shield 5 is fixedly installed on the upper part of the water tank 1. A three-axis electric slide 6 is fixedly installed inside the splash shield 5. An induction radar 7 is fixedly installed on the upper part of the front inner wall of the splash shield 5. The induction radar 7 is electrically connected to the controller 4.

[0031] The connecting frame 8 is fixedly mounted on the three-axis electric slide table 6. A dual-axis motor 9 is fixedly mounted inside the connecting frame 8. The dual-axis motor 9 is electrically connected to the controller 4. A first screw 10 is fixedly mounted on each of the two output shafts of the dual-axis motor 9, and the threads of the two first screws 10 are set in opposite directions.

[0032] Two movable insert rods 11 are respectively movably inserted into slots 12 opened on the left and right sides of the connecting frame 8. The first screw 10 is rotatably inserted into the slot 12 through a bearing. The movable insert rod 11 is rotatably sleeved on the first screw 10 through a thread. One end of the movable insert rod 11 is fixedly provided with an upper support frame 13. Guide insert rods 20 are fixedly provided on the side wall of the upper support frame 13 on both the front and rear sides of the movable insert rod 11. The guide insert rods 20 are movably inserted into the connecting frame 8. The guide insert rods 20 can not only provide auxiliary guidance for the movement of the upper support frame 13, but also provide support for the upper support frame 13, making the upper support frame 13 more stable.

[0033] A first connecting rod 14, of which there are several, is respectively hinged to the bottom of two upper support frames 13. The lower end of the first connecting rod 14 is hinged to a second connecting rod 15. Two lower support frames 23 are respectively hinged to the lower ends of several second connecting rods 15 on the left and right sides. An angle adjustment component 16 connected to the lower support frame 23 is provided on the upper support frame 13.

[0034] The piezoelectric ceramic intelligent nozzle 17 comprises several units, which are respectively fixedly installed on the side walls of several first-link 14 and second-link 15. The piezoelectric ceramic intelligent nozzle 17 is electrically connected to the controller 4. A water supply pipe 18 is fixedly installed inside each first-link 14 and second-link 15. The piezoelectric ceramic intelligent nozzle 17 is connected to the water supply pipe 18. The delivery pipe 3 is connected to the water supply pipe 18 through a flexible hose. The upper support frame 13 and the lower support frame 23 are both arc-shaped structures. The several first-link 14 and second-link 15 on the left and right sides are distributed at equal angles, which can realize semi-circular spraying of the workpiece and reduce the ineffective spraying area.

[0035] The angle adjustment component 16 includes:

[0036] Two internal threaded cylinders 16-1 are fixedly installed on the upper part of two lower support frames 23 respectively. A second screw 16-2 is inserted into the internal threaded cylinder 16-1 by means of thread rotation. The upper end of the second screw 16-2 is inserted into the upper support frame 13 by means of bearing rotation.

[0037] The control motor 16-3 is fixedly mounted on the upper support frame 13 on the left side. The control motor 16-3 is electrically connected to the controller 4. The control motor 16-3 is covered with a waterproof cover 19, which is also fixedly mounted on the upper support frame 13 on the left side. The waterproof cover 19 can protect the control motor 16-3 and prevent cooling water from splashing onto the control motor 16-3 and causing damage. The two upper support frames 13 have a linkage rod 16-4 inserted into their opposite side walls through bearings. The output shaft of the control motor 16-3 is connected to the linkage rod 16-4 on the left side. The upper end of the second screw 16-2 is connected to the linkage rod 16-4 through a bevel gear pair.

[0038] Linkage sleeve 16-5 is inserted into the lower part of the connecting frame 8 via a bearing and is movably sleeved on linkage rod 16-4. Through the transmission of linkage rod 16-4, linkage sleeve 16-5 and bevel gear pair, synchronous transmission of the two second screws 16-2 can be achieved. When the second screw 16-2 rotates, the distance between the upper support frame 13 and the lower support frame 23 can be changed, the included angle between the first connecting rod 14 and the second connecting rod 15 and the spray angle of the piezoelectric ceramic intelligent nozzle 17 can be adjusted.

[0039] When using this utility model, the robotic arm sends the workpiece into the water tank 1. Then, the sensing radar 7 identifies the position and size of the workpiece. The controller 4 controls the three-axis electric slide 6 to move the connecting frame 8 to a suitable height above the workpiece. Then, the control motor 16-3 drives the left linkage rod 16-4 to rotate. With the cooperation of the linkage sleeve 16-5, the linkage rods 16-4 on both sides rotate synchronously. The linkage rod 16-4 drives the second screw 16-2 to rotate through the bevel gear pair, so that the internal threaded cylinder 16-1 can drive the lower support frame 23 to move up and down. Adjusting the distance between the upper support frame 13 and the lower support frame 23 changes the size of the included angle formed between the first connecting rod 14 and the second connecting rod 15. At this time, the first connecting rod 14 and the second connecting rod 15... All piezoelectric ceramic intelligent nozzles 17 on the connecting rod 15 can face the workpiece, reducing ineffective spraying areas. Simultaneously, the dual-axis motor 9 can drive the first screw 10 to rotate, causing the moving insert rod 11 to move the upper support frame 13. This allows for adjustment of the position of the piezoelectric ceramic intelligent nozzles 17 on both sides according to the workpiece's size. Then, the water pump 2 is started, delivering water to the piezoelectric ceramic intelligent nozzles 17 through the delivery pipe 3 and water supply pipe 18. The piezoelectric ceramic intelligent nozzles 17 can then spray and quench the workpiece. During the spraying and quenching process, the spraying distance of the piezoelectric ceramic intelligent nozzles 17 can be dynamically adjusted according to the material and quenching process. Several piezoelectric ceramic intelligent nozzles 17 can also be individually adjusted for spray flow and pressure via the electrical control signal from the controller 4. The nozzle distribution position and angle can be adjusted according to the size, material, or process of the workpiece to be quenched. By precisely controlling the spraying distance, combined with pressure and flow adjustment, the quenching deformation of the workpiece can be effectively reduced.

[0040] Compared with the prior art, the beneficial effects of this utility model are:

[0041] By cooperating with the controller 4, the three-axis electric slide 6, the sensor radar 7, the connecting frame 8, the dual-axis motor 9, the first screw 10, the moving insert rod 11, the upper support frame 13, the first connecting rod 14, the second connecting rod 15 and the angle adjustment component 16, the spraying position of the piezoelectric ceramic intelligent nozzle 17 can be adjusted so as to adapt to the size of the quenched workpiece and expand the scope of application.

[0042] The splash guard 5 above the water tank 1 effectively reduces the phenomenon of cooling water splashing everywhere during the spray quenching process.

[0043] The filter plate 21 can filter out impurities such as metal fragments in the cooling waste liquid, and prevent the pipe from being blocked due to excessive metal fragments and other impurities during the discharge process.

[0044] The guide rod 20 not only provides auxiliary guidance for the movement of the upper support frame 13, but also provides support for the upper support frame 13, making the upper support frame 13 more stable.

[0045] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
