Description

Technical Field

[0001] The utility model relates to a quenching device, in particular to a quenching device for precision spring processing, belonging to the technical field of spring quenching devices. Background Art

[0002] A spring is a mechanical component that uses elasticity to work. In daily life, we usually use springs to store and release energy, and use its elastic effect to buffer and reduce shock, thereby reducing the impact and vibration during mechanical movement. However, in the process of spring processing, especially for some more precise springs, people usually need to quench the springs in order to improve the hardness or wear resistance of precision springs.

[0003] When a quenching device is used to quench a spring, the spring is usually placed in a container and then immersed in a quenching medium and in full contact with the quenching medium for quenching. However, in order to improve the quenching efficiency of the spring, people often place multiple springs together in a container for simultaneous quenching. However, when multiple springs are placed in a container, stacking is likely to occur, which may result in the quenching medium and the spring not being able to fully contact, thereby reducing the quenching effect of the spring. Utility Model Content

[0004] The utility model provides a quenching device for precision spring processing, so as to solve the problem in the prior art that the springs may not be in full contact with the quenching medium due to the stacking of multiple springs.

[0005] The utility model is implemented by the following technical scheme: a quenching device for precision spring processing, comprising a box body, a mounting plate is arranged above the box body, a shaking mechanism is arranged on the upper surface of the mounting plate, the shaking mechanism comprises a movable plate and a motor, a bottom surface of the movable plate is fixedly connected with symmetrical sliding rods, two sliding rods are extended to the bottom of the mounting plate and are slidably connected to the mounting plate, a bottom surface of the movable plate is fixedly connected with symmetrical return springs, and two return springs are fixedly connected to the upper surface of the mounting plate;

[0006] The bottom ends of the two sliding rods are fixedly connected with connecting pads, the bottom surface of the movable plate is fixedly connected with a fixing block, the motor is installed on the upper surface of the mounting plate, the output end of the motor is fixedly connected with a driving disk, and the outer surface of the driving disk is fixedly connected with a driving arm.

[0007] Furthermore, a spring containing bucket is provided inside the box body, and the two connecting pads are fixedly connected to the outer surface of the spring containing bucket. As the connecting pads move up and down, the spring containing bucket can be driven to move up and down. A group of reserved openings are provided on the outer surface of the spring containing bucket, and the quenching medium can enter the spring containing bucket through the reserved openings and contact the spring.

[0008] Specifically, four fixing pads are fixedly connected to the outer surface of the box body, the upper surface of each fixing pad is fixedly connected to a support rod, and each support rod is fixedly connected to the bottom surface of the mounting plate, so that the mounting plate can be supported and fixed by the support rods.

[0009] Furthermore, the inner wall of the spring containing bucket is threadedly connected with a closing cover, and the outer surface of the box body is fixedly connected with a drain pipe, through which the used quenching medium can be discharged. When the quenching process is performed, the drain pipe can be closed with a rubber plug, and after placing multiple springs in the spring containing bucket, the spring containing bucket can be closed by rotating the closing cover.

[0010] Furthermore, symmetrical motors are mounted on the outer surface of the box, and the output ends of the two motors extend into the interior of the box and are rotatably connected to the box. The motors are mounted on the outer surface of the box via brackets.

[0011] Preferably, the output ends of the two motors are fixedly connected with stirring blades, and the bottom surface of the box is fixedly connected with a base. By starting the motor, the stirring blades can be driven to rotate, thereby stirring the quenching medium, so that the quenching medium can fluctuate, further ensuring the contact between the spring and the quenching medium.

[0012] The utility model provides a quenching device for precision spring processing, which has the following beneficial effects:

[0013] 1. The quenching device for precision spring processing is configured by the cooperation between the box body, the mounting plate, the shaking mechanism and the spring containing bucket. The springs in the spring containing bucket can be separated from each other under the resistance of the quenching medium by the up and down movement of the spring containing bucket, so that the springs can be in more comprehensive contact with the quenching medium, avoiding the situation that multiple springs cannot be in more comprehensive contact with the quenching medium due to stacking, and further ensuring the quenching treatment effect of the springs.

[0014] 2. The quenching device for precision spring processing, the coordinated arrangement between the driving disk, the driving arm, the fixed block, the movable plate, the reset spring and the spring containing bucket can effectively ensure full contact between the spring and the quenching medium. As the driving disk rotates, the movable plate can be driven to move upward under the action of the driving arm, and at the same time, the spring containing bucket can be driven to move downward under the action of the reset spring. Then, under the resistance of the quenching medium, the spring in the spring containing bucket will shake, thereby forming a gap between the springs, ensuring full contact between the spring and the quenching medium.
