[0002] Auto parts are the various units that make up the entire car and are products that serve the car. In order to improve the hardness and performance of auto parts, they usually need to be quenched during the production process.

[0003] A Chinese patent with the announcement number CN215209564U discloses a high-frequency quenching device for automobile parts production, including a quenching machine, a heating rod and a gear. The outer wall of the quenching machine is fixedly connected to a heating box, the heating rod extends to the interior of the heating box, the lower side wall of the heating box is fixedly connected to a pneumatic cylinder, the inner side wall of the heating box is slidingly provided with a rectangular plate, the upper surface of the rectangular plate is fixedly connected to a cylinder, the upper surface of the cylinder is provided with a pair of rectangular grooves, and the rectangular grooves are rotatably connected to the inside of the pressure claws. This high-frequency quenching device for automobile parts production, by providing components such as pressure claws, cylinders, and a driving device, can effectively clamp and fix the gears during quenching. At the same time, the driving device can effectively control the pressure claws, thereby preventing the gears from contacting other objects when moving during the quenching process, causing them to break away from the fixed position of the cylinder and fall.

[0004] The above-mentioned high-frequency quenching device for automobile parts production still has some problems when in use. When quenching a workpiece, only one workpiece can be quenched at a time, and re-clamping is required before processing the next workpiece, resulting in a significant reduction in overall processing efficiency. Therefore, a quenching device for automobile parts is proposed to address the above-mentioned problems. Utility Model Content

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: the present invention is a quenching device for automobile parts, comprising a base; a central shaft is rotatably mounted on the base, a rotating disk is fixedly connected to the top of the central shaft, a driven gear is sleeved on the bottom end of the central shaft, a first motor is mounted on the bottom side of the base, a driving gear is mounted on the output end of the first motor, and the driving gear and the driven gear are meshed with each other, four pneumatic cylinders are mounted on the top side of the rotating disk, the action end of each pneumatic cylinder is equipped with a pneumatic rod, the top end of each pneumatic rod is fixedly connected to a placement plate, after the quenching of one workpiece is completed, the first pneumatic cylinder is started when the next workpiece is quenched. An electric motor causes the driving gear to rotate, forcing the driven gear to drive the central shaft to rotate, and then the rotating disk drives the workpiece that is fixed in contact to rotate. When the next workpiece is transferred to the quenching area, the first motor stops operating and repeats the quenching steps, so that the workpiece can be quenched. Through the setting of the rotary rotation mechanism, multiple workpieces can be quenched continuously without re-clamping, which greatly improves the quenching efficiency. Moreover, through automated operation, since automated devices usually have higher precision and stability, it can ensure that each workpiece maintains the same clamping position and posture during the quenching process, thereby greatly improving the processing accuracy and consistency.

Both ends of each bidirectional screw are provided with sliders, and the sliders are arranged in the grooves. The top side of each slider is fixed with an arc-shaped resistance plate. When quenching automobile parts, multiple workpieces to be processed must be placed on the placement plate in turn, and then the second motor is started to rotate the bidirectional screw, thereby moving the slider in the groove, so that the two sliders drive the two arc-shaped resistance plates away from each other until the two arc-shaped resistance plates move to the inner wall box of the workpiece, thereby being able to fix the workpiece by resistance, and avoiding the phenomenon of the workpiece falling off during the quenching process.

When the workpiece moves up into the heating ring, the workpiece can be heated under the action of the heating ring. After the workpiece is heated, under the action of the pneumatic cylinder, the placement plate drives the workpiece that is fixed in contact to move down into the fixed ring. At this time, the water pump is started to draw out the water in the water tank through the suction pipe, and flows into the connecting pipe through the delivery pipe, and then flows into the annular pipe, and finally sprayed on the surface of the workpiece through the nozzle, so that the heated workpiece can be cooled and cooled, thereby achieving the purpose of quenching the workpiece.

[0009] The utility model is beneficial in that:

[0010] 1. After the workpiece is fixed in contact with each other, the pneumatic cylinder is started to make the pneumatic rod drive the placement plate to move up, thereby causing the fixed workpiece to move up as well. When the workpiece moves up into the heating ring, the heating ring can heat the workpiece. After the workpiece is heated, the pneumatic cylinder drives the placement plate to move down into the fixing ring. At this time, the water pump is started to pump water out of the water tank through the water pump pipe, and flows into the connecting pipe through the delivery pipe, then flows into the annular pipe, and finally sprayed on the surface of the workpiece through the nozzle, thereby cooling the heated workpiece and achieving the purpose of quenching the workpiece.

[0011] 2.

After the quenching of one workpiece is completed, when the next workpiece is quenched, the first motor 4 is started to rotate the driving gear 5, forcing the driven gear 3 to drive the central axis to rotate, thereby rotating The disk 2 drives the workpiece that has been fixed in contact to rotate.
