Description

Technical Field

[0001] The utility model relates to the technical field of quenching devices, and more specifically to a novel pin shaft quenching device. Background Art

[0002] CNC hardening machines are induction heat treatment devices that perform medium-frequency induction heating and liquid spray quenching on small and medium-sized, special-shaped parts such as pins, flanges, and flanges. A CNC system precisely controls parameters such as inductor movement, heating power, heating time, and cooling method. When a gear or shaft is placed on the hardening machine's worktable, the inductor generates an alternating magnetic field, generating eddy currents within the workpiece, rapidly heating it. Once the hardening temperature is reached, water or other cooling media is sprayed on the workpiece for rapid cooling, completing the hardening process.

[0033] The first embodiment of the present utility model is as follows:

[0034] The novel pin 12 quenching device comprises a base 2 and a body arranged on the upper portion of the base 2. The body comprises an upper body 1 and a middle body 3. An open working area is provided in the middle of the middle body 3. The quenching work is carried out in the working area. Several quenching assemblies are evenly arranged in the working area. A feeding assembly is also provided in the working area.

[0035] The quenching assembly includes a servo motor 10 arranged on the base 2, and the upper end of the output shaft of the servo motor 10 is connected to a vertically arranged rotating rod 9, which is driven to rotate by the servo motor 10. The quenching assembly also includes a hydraulic cylinder arranged on the upper part of the fuselage, and the lower end of the piston rod of the hydraulic cylinder is connected to a lifting column 11. The lower end of the rotating rod 9 and the lower end of the lifting column 11 are both provided with a convex head 13, and both ends of the pin shaft 12 are provided with a groove adapted to the convex head 13. The pin shaft 12 is placed on the rotating rod 9, and then the hydraulic cylinder drives the lifting column 11 to move downward to press the pin shaft 12. At this time, the convex head 13 engages with the groove to fix the pin shaft 12. When the servo motor 10 rotates, the rotating rod 9 drives the pin shaft 12 to rotate.

[0036] After quenching is completed, the hydraulic cylinder drives the lifting rod to rise, and the pin 12 can be removed at this time.

[0037] A notch 15 is provided on the inner facade of the middle fuselage 3. The quenching assembly also includes a hydraulic cylinder arranged inside the fuselage. A lifting plate is connected to the piston rod of the hydraulic cylinder, which drives the lifting plate to move up and down through the hydraulic cylinder. The middle part of the lifting plate passes through the notch 15 and is in the working area. A clamping seat 14 is provided on the part of the lifting plate in the working area. The internal clamp of the clamping seat 14 holds an induction coil 5. The axis of the induction coil 5 is in the same straight line as the axis of the rotating rod 9 and the lifting column 11. The induction coil 5 is connected to an electronic control system. When the pin shaft 12 is fixed on the rotating rod 9 and the lifting rod, the lifting plate drives the induction coil 5 to move downward to the pin shaft 12. At this time, the electronic control system is started, and a high-frequency alternating magnetic field is generated by the induction coil 5. The pin shaft 12 will be induced and generate eddy currents, thereby causing the workpiece to heat up. The heating of the induction coil 5 has the advantages of fast heating speed, uniform heating, and low energy consumption, thereby completing the heating of the surface of the pin shaft 12.

[0038] The quenching assembly also includes a water channel device, which includes a return water tank arranged inside the base 2. The upper part of the return water tank is open. The quenching liquid flows into the return water tank after quenching. The quenching liquid is driven to the nozzle 4 by the water pipe and water pump arranged inside the body.

The rear end of the feeding transverse trough 6 is connected to the upper end of the feeding vertical trough 7. An opening is provided on the front facade of the fuselage and is connected to the feeding transverse trough 6. The thickness of the feeding transverse trough 6 is slightly larger than the thickness of the feeding rack 8. The length of the feeding rack 8 is equal to the distance between the outer ends of the two feeding transverse troughs 6. The feeding rack 8 enters the feeding transverse trough 6 from the opening, pushes the feeding rack 8 inward to the end of the feeding transverse trough 6, and then moves it downward along the feeding vertical trough 7 to its bottom. The horizontal height of the lower end of the feeding vertical trough 7 is located in the middle of the rotating rod 9, and the feeding rack 8 will not affect the rotation of the pin shaft 12.

[0041] It should be noted that, since the length of the loading rack 8 is equal to the distance between the outer ends of the two loading transverse grooves 6, it is ensured that the loading rack 8 cannot move left and right when entering the loading transverse groove 6. Since the width of the loading vertical groove 7 is equal to the width of the loading rack 8, it is ensured that the loading rack 8 cannot move forward and backward in the loading vertical groove 7. It is ensured that the use of the loading rack 8 to prevent the pin shaft 12 can ensure its accurate position at one time and no subsequent adjustment is required.

[0042] The loading rack 8 is provided with five through holes 81 , which can complete the loading of five pins 12 at one time.

[0043] A handle 82 is provided in the middle of the loading rack 8 to facilitate taking, placing and loading.

[0044] When the loading rack 8 is in the working state, the lifting rod 12 is lifted and the lifting frame 8 is lifted, and the lifting frame 8 is lifted and the workpiece is heated. When the workpiece is in the working state, the lifting rod 12 is lifted and the lifting frame 8 is lifted, the lifting frame 8 is lifted and the workpiece is heated. When the workpiece is in the working state, the lifting rod 12 is lifted and the lifting frame 8 is lifted, the lifting frame 8 is lifted and the workpiece is heated. When the workpiece is in the working state, the lifting rod 12 is lifted and the lifting frame 8 is lifted, the lifting frame 8 is lifted and the workpiece is heated. When the workpiece is in the working state, the lifting rod 12 is lifted and the lifting frame 8 is lifted, the lifting frame 8 is lifted and the workpiece is heated. When the workpiece is in the working state, the lifting rod 12 is lifted and the lifting frame 8 is lifted, the lifting frame 8 is lifted and the workpiece is heated. When the workpiece is in the working state, the lifting rod 12 is lifted and the lifting frame 8 is lifted, the lifting frame 8 is lifted and the workpiece is heated. When the workpiece is in the working state, the lifting rod 12 is lifted and the lifting frame
