Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figures 1 to 6The excavator bucket tooth quenching equipment of this utility model includes a base plate 1, a controller 2 mounted on the base plate 1, a quenching furnace 3 mounted on the base plate 1 for quenching bucket teeth, a gantry sliding frame 4 fixedly connected to the base plate 1, a first fixed frame 5 fixedly connected to the gantry sliding frame 4, a first electric push rod 6 fixedly mounted on the first fixed frame 5, a first connecting rod 7 connected to the telescopic rod of the first electric push rod 6, a movable block 8 slidably connected to the gantry sliding frame 4, the movable block 8 connected to the first connecting rod 7, a second electric push rod 9 fixedly mounted on the movable block 8, a second connecting rod 10 connected to the bottom end of the telescopic rod of the second electric push rod 9, a connecting plate 11 connected to the bottom end of the second connecting rod 10, a first motor 12 fixedly mounted on the connecting plate 11, and a first rotating shaft 13 connected to the bottom end of the output shaft of the first motor 12. A clamp 14 is connected to the bottom end of the rotating shaft 13. The clamp 14 is used to clamp the bucket teeth. A first distance sensor 15 is installed on the moving block 8. A second distance sensor 16 is installed on the gantry sliding frame 4. A liquid carrier tank 17 is fixedly connected to the base plate 1. Multiple second fixed frames 18 are fixedly connected to the liquid carrier tank 17. A second motor 19 is fixedly installed on the second fixed frame 18. A second rotating shaft 20 is connected to the output shaft of the second motor 19. The second rotating shaft 20 is rotatably connected to the liquid carrier tank 17. An agitator 21 is connected to the second rotating shaft 20. The agitator 21 is used to stir the quenching liquid. A temperature sensor 22 is installed on the liquid carrier tank 17. The temperature sensor 22 is used to detect the temperature of the quenching liquid. A cooler 23 is installed on the liquid carrier tank 17. A transmission pipe 24 is connected between the cooler 23 and the liquid carrier tank 17.

[0021] The controller 2 is equipped with a start button and a cool button.

[0022] A timer is set on controller 2.

[0023] A heat insulation layer is provided on the connecting plate 11.

[0024] The clamp 14 consists of a fixed insertion rod and a fixed nut.

[0025] The working principle of this utility model is as follows: the first distance sensor is provided with a first threshold and a second threshold, and the value of the first threshold is greater than the value of the second threshold.

[0026] The second distance sensor is equipped with a first threshold and a second threshold, wherein the value of the first threshold is greater than the value of the second threshold.

[0027] The temperature sensor is equipped with a first threshold and a second threshold, with the value of the first threshold being greater than the value of the second threshold.

[0028] After the bucket teeth are hung on the gripper, the gripper secures and holds the bucket teeth. Then, the start button is pressed to control the second electric push rod to work. The second electric push rod drives the second connecting rod, the connecting plate, the first motor, the first rotating shaft, and the gripper to descend, causing the bucket teeth to descend into the quenching furnace. When the distance between the connecting plate and the first distance sensor reaches the first threshold preset by the first distance sensor, the second electric push rod is controlled to stop working. At the same time, the first motor is controlled to drive the first rotating shaft, the gripper, and the bucket teeth to rotate, so that the bucket teeth can be heated evenly, and the timer starts working.

[0029] After the quenching time of the bucket teeth reaches the threshold set by the timer, the first motor is stopped, and the second electric push rod is reversed. The second electric push rod drives the second connecting rod, the connecting plate, the first motor, the first rotating shaft, and the gripper to rise. When the distance between the connecting plate and the first distance sensor reaches the second threshold preset by the first distance sensor, the second electric push rod is stopped, and the first electric push rod is activated. The first electric push rod drives the first connecting rod, the moving block, the second electric push rod, the second connecting rod, the connecting plate, the first motor, the first rotating shaft, and the gripper to move. When the distance between the moving block and the second distance sensor reaches the first threshold preset by the second distance sensor, the first electric push rod is stopped, so that the bucket teeth are positioned above the liquid carrying tank.

[0030] After the quenching fluid is injected into the liquid carrier tank, pressing the cooling button controls the second electric push rod and the second motor to operate. The second motor drives the second rotating shaft and the agitator to rotate, and the agitator stirs the quenching fluid. The second electric push rod drives the second connecting rod, the connecting plate, the first motor, the first rotating shaft, and the clamp to descend, causing the bucket teeth to descend into the liquid carrier tank. This allows the bucket teeth to contact the quenching fluid, improving the quenching quality and cooling the quenching fluid. A temperature sensor detects the temperature of the quenching fluid. When the temperature of the quenching fluid exceeds a preset first threshold, the cooler is activated to cool the quenching fluid, preventing excessively high temperatures caused by continuous use and ensuring optimal quenching results. When the temperature of the molten metal falls below the second threshold preset by the temperature sensor, the cooler is stopped. After the bucket teeth have cooled down, pressing the cooling button again causes the second electric push rod to reverse and the second motor to stop. The second electric push rod drives the second connecting rod, the connecting plate, the first motor, the first rotating shaft, and the clamp to rise to their reset position. When the clamp wants to return to the top of the quenching furnace, the first electric push rod is reversed. The first electric push rod drives the first connecting rod, the moving block, the second electric push rod, the second connecting rod, the connecting plate, the first motor, the first rotating shaft, and the clamp to move in the opposite direction. When the distance between the moving block and the second distance sensor reaches the second threshold preset by the second distance sensor, the first electric push rod is stopped.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
