Description

Technical Field

[0002] Shock-resistant anti-loosening nuts are special nuts that are primarily used to prevent automatic loosening under vibration or stress conditions, ensuring the stability and reliability of the connection. Quenching can significantly increase the surface hardness of shock-resistant anti-loosening nuts, thereby enhancing their wear resistance and deformation resistance. This is particularly important in situations where high stress and high-frequency vibration are required.

[0003] The quenching devices currently in use still have the following problems: 1. There is usually a lack of a blocking structure in the feed hopper, which causes the quenching liquid to splash out easily when the shock-resistant and anti-loosening nuts are fed, posing a safety hazard; 2. The quenching liquid cannot be automatically circulated when the shock-resistant and anti-loosening nuts are discharged after quenching, resulting in temperature deviations in the quenching liquid at different positions, affecting the subsequent quenching effect of the shock-resistant and anti-loosening nuts.

[0016] A quenching method for producing shock-resistant and anti-loosening nuts:

[0018] 2) Pour the quenched anti-vibration and anti-loosening nuts into the feed hopper, and then fully extend the output shaft of the linear electric cylinder A;

[0019] 3) Start the drive motor to slowly move the anti-vibration and anti-loosening nut from right to left, and then completely retract the output shaft of the linear electric cylinder A;

[0020] 4) When the quenched anti-vibration anti-loosening nuts need to be discharged, retract the output shafts of the two linear electric cylinders B and wait for the quenched anti-vibration anti-loosening nuts to be completely discharged;

[0021] 5) Extend the output shafts of the two linear electric cylinders B completely, and then quench the next batch of shock-resistant and anti-loosening nuts.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. When the driving motor of the present invention is working, the circular driving rod drives the spiral blade to rotate, so that the shock-resistant anti-loosening nut in the circular quenching cylinder moves slowly from right to left, thereby realizing automatic quenching of the shock-resistant anti-loosening nut.

[0024] 2. In the present invention, when the output shaft of the linear electric cylinder A is in a retracted state, the shock-resistant anti-loosening nut to be quenched can pass through the feed slot A and contact the U-shaped protective frame; when the output shaft of the linear electric cylinder A is in an extended state, the shock-resistant anti-loosening nut on the U-shaped protective frame can pass through the feed slot B.

[0025] 3. In the present invention, when the hardened, shock-resistant, anti-loosening nut needs to be removed, the operator retracts the output shafts of the two linear electric cylinders B. When the arc-shaped protrusions come into contact with the rectangular force-bearing rods, the arc-shaped protrusions push the rectangular force-bearing rods upward, allowing the hardened, shock-resistant, anti-loosening nut to be removed through the gap below the arc-shaped sealing plate. When the output shafts of the two linear electric cylinders B extend, the arc-shaped sealing plate automatically returns to its original position due to its own weight and the elastic force of the two coil springs.

[0026] In addition, when the output shafts of the two linear electric cylinders B retract, the quenching liquid in the quenching liquid storage tank enters the rectangular shell through a row of one-way valves A under the action of the rectangular movable plate, which can automatically lower the height of the quenching liquid in the quenching liquid storage tank, and prevent the quenching liquid in the quenching liquid storage tank from being discharged along with the shock-resistant anti-loosening nuts after quenching; when the output shafts of the two linear electric cylinders B extend, the quenching liquid in the rectangular shell enters the quenching liquid storage tank through a row of circulation pipes. On the one hand, it can automatically increase the height of the quenching liquid in the quenching liquid storage tank, which is convenient for the next quenching of the shock-resistant anti-loosening nuts; on the other hand, it realizes the automatic circulation of the quenching liquid in the quenching liquid storage tank, making the temperature of the quenching liquid in the quenching liquid storage tank more uniform.
