Abstract
Description
Technical Field
[0001] This utility model relates to the field of quenching equipment technology, and in particular to a heating and quenching device for automotive parts. Background Technology
[0002] Heating and quenching is an important method in metal heat treatment, mainly used to improve the hardness, strength, and wear resistance of metallic materials. It involves heating the metal to a certain temperature and then rapidly cooling it, thereby altering the metal's internal structure and improving its properties.
[0003] When quenching a small number of small gears in automobiles, workers typically use hand clamps to hold the gears and suspend them in the induction coil of a high-frequency induction heater. Due to human factors, manual clamping results in poor stability, and inconsistent distances between different parts of the gear's outer ring and the induction coil. This leads to uneven quenching and hardness distribution, resulting in poor wear resistance, deformation, or cracking, thus reducing the gear's service life. Therefore, some quenching devices are equipped with a workbench, on which the gear is mounted on a rotating shaft. Although the distance between the gear and the induction coil is fixed, if the distance between the gear and the rotating shaft is too small, it is difficult to remove the gear from the shaft; if the distance is too large, it is not securely fixed during rotation, causing wobbling. This leads to uneven heating of different parts of the gear, resulting in uneven hardness, deformation, cracks, and other defects, affecting the gear's service life and performance.
[0004] Therefore, this application provides a heating and quenching apparatus for automotive parts to solve the problems mentioned in the background art. Utility Model Content

The control box is electrically connected to the cylinder, the slide module and the finger cylinder to control the cylinder's movement.
[0014] A further improvement of this utility model is that an inlet valve is connected to the upper part of one side wall of the cooling pool, and an outlet valve is connected to the lower part of the opposite side wall of the cooling pool.

[0030] The present invention will be further explained below with reference to specific embodiments.
[0031] like Figures 1-6As shown, this embodiment provides a heating and quenching device for automotive parts, including a support platform 1, a high-frequency induction heater 2 and a cooling pool 3 on the support platform 1, the induction coil 21 of the high-frequency induction heater 2 extending horizontally to the middle of the upper part of the cooling pool 3; a water inlet valve 31 is connected to the upper part of one side wall of the cooling pool 3, and a water outlet valve 32 is connected to the lower part of the opposite side wall of the cooling pool 3; a water level gauge 33 is also connected to one side wall of the cooling pool 3, the water inlet valve 31 and the water outlet valve 32 are used to control the water inlet and outlet of the cooling pool 3, and to control the water level in the cooling pool 3; a water level gauge 33 is also connected to one side wall of the cooling pool 3, and the water level gauge 33 displays the water level of the cooling pool 3; a moving mechanism 5 is provided inside the cooling pool 3, the moving mechanism 5 is used to place gear parts, a gantry frame 4 is also provided on the support platform 1 above the cooling pool 3, a clamping device 6 is provided on the gantry frame 4, and the clamping device 6 clamps the gear parts placed by the moving mechanism 5 into the induction coil 21.
[0032] like Figures 5-6 As shown, in this embodiment, the moving mechanism 5 includes a cylinder 51, which is disposed on the bottom surface of the support platform 1. The telescopic rod of the cylinder 51 passes through the bottom surfaces of the support platform 1 and the cooling pool 3, and a placement plate 52 is disposed on the top. A retaining shaft 53 is disposed on the placement plate 52. At least two grooves 54 are evenly disposed on the outer circumference of the retaining shaft 53. The grooves 54 are used for the retaining block 67 in the clamping device 6 to extend into and clamp the gear component. The retaining shaft 53 is fitted onto the inner ring of the gear component. The extension and retraction of the telescopic rod of the cylinder 51 drives the placement plate 52 and the retaining shaft 53 to move up and down, thereby driving the gear component fitted onto the retaining shaft 53 to move up and down. The cylinder 51 moves upward to fit the gear component. On the clasp 53, the placement plate 52 supports the bottom of the gear component. Then, the clamping device 6 clamps the gear component from the moving mechanism 5 into the induction coil 21 for quenching. After quenching, the clamping device 6 places the gear component on the placement plate 52 and the clasp 53. The cylinder 51 moves downward to cool the gear component, improving its hardness and strength. After cooling, the cylinder moves upward to remove the gear component. There is a gap of 1 to 5 mm between the diameter of the clasp 53 and the inner ring of the gear component. This gap facilitates the removal of the gear component after quenching, simplifies the operation, prevents wear between the gear and the clasp 53 during removal, and improves the life of the gear.
[0033] like Figures 3-4As shown, in this embodiment, the clamping device 6 includes an inverted L-shaped plate 61 on the top of the gantry frame 4, and a slide module 62 on the side of the inverted L-shaped plate 61. The slide module 62 is an existing device that can slide up and down. A mounting plate 63 is provided on the bottom surface of the slider of the slide module 62, and a rotary motor 68 is provided on the bottom surface of the mounting plate 63. The output shaft of the rotary motor 68 is nested in the middle of the circular plate 69. There is a gap between the rotary motor 68 and the circular plate 69 to facilitate rotation. The output shaft of motor 68 drives the circular plate 69 to rotate, which in turn drives the finger cylinder 64, which is fixed to the bottom surface of the circular plate 69, to rotate. The finger cylinder 64 is an existing device and will not be described in detail here. The bottom surface of the gripper of the finger cylinder 64 is connected to an inverted L-shaped block 65. A protrusion 66 is provided on the outer side of the lower part of the inverted L-shaped block 65, which engages with a clamping block 67. Both the inverted L-shaped block 65 and the clamping block 67 are made of ceramic materials; for example, alumina ceramic has low thermal conductivity and is suitable for high-frequency quenching fixtures. The finger cylinder 64 has at least two grippers, preferably three, the number of which matches the number of grooves 54. The clamping block 67 and groove 54 are vertically aligned. The length and width of the groove 54 are greater than the total horizontal length and width of the clamping block 67 and protrusion 66, facilitating the clamping block 67's entry into the groove 54 to clamp the gear component. The outer surface of the clamping block 67 is arc-shaped, ensuring it fully contacts the inner ring of the gear component, improving clamping stability and effectiveness. The clamping block 67 and the inverted L-shaped block 65 are fixed together with screws for replacing the clamping block 67, preventing deformation due to prolonged use and ensuring the clamping effect of the clamping device 6 is not affected, thus improving the clamping stability of the clamping device 6. The centers of the finger cylinder 64, induction coil 21, and clamping shaft 53 are longitudinally aligned, effectively ensuring a consistent horizontal distance between the outer ring of the gear component and the induction coil 21, improving the uniformity of quenching, and consequently increasing the service life and performance of the gear component.
[0034] Furthermore, a control box 7 is also installed on one side of the high-frequency induction heating machine 2 on the support platform 1. The control box 7 is electrically connected to the cylinder 51, the slide module 62 and the finger cylinder 64 respectively, and controls the operation of the cylinder 51, the slide module 62, the rotary motor 68 and the finger cylinder 64. In addition, each cylinder is also connected to an air source (not shown in the figure).
[0035] This utility model also provides a working principle for a heating and quenching device for automotive parts: First, the user mounts the gear component onto the clamping shaft 53, and the placement plate 52 supports the bottom of the gear component. At this time, the clamping shaft 53 is located below the induction coil 21, and the water level in the cooling pool 3 is lower than the upper surface of the placement plate 52. The slide module 62 in the clamping device 6 starts moving downward until the clamping block 67 enters the groove 54. The finger cylinder 64 starts, and the gripper in the finger cylinder 64 moves outward, driving the inverted L-shaped block 65 to move outward, thereby driving the clamping block 67 to abut against the inner ring wall of the gear component. The slide module 62 moves upward until the gear component is inside the induction coil 21. The high-frequency induction heating machine 2 starts, and at the same time, the rotating motor 68 rotates forward and backward. The rotation drives the finger cylinder 64 to rotate forward and backward, which in turn drives the gear component to rotate forward and backward, ensuring that the gear component is heated evenly by the induction coil 21. After the high-frequency induction heating machine 2 stops at the set time, the slide module 62 moves down to place the gear component on the clamping shaft 53, the gripper in the finger cylinder 64 moves inward, and at the same time the slide module 62 moves up, and the telescopic rod of the cylinder 51 retracts, immersing the gear component in the cooling pool 3 for cooling. The telescopic rod of the cylinder 51 extends, and the gear component is exposed above the water surface. The user removes the gear component from the clamping shaft 53 and the placement plate 52, and the quenching of the gear component is completed. The finger cylinder controls the clamping block to clamp the gear component, ensuring stable clamping and even heating of all parts of the gear component, thereby improving the service life and performance of the gear.
[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
