Description

Technical Field

[0001] This utility model relates to a quenching device, and more particularly to a quenching device for bearing housing production. Background Technology

[0002] Quenching is a heat treatment process that involves heating a metal material to above a critical temperature and then rapidly cooling it. This process causes significant changes in the structure and properties of the metal material, both on the surface and inside. The main purpose of quenching is to increase the hardness and strength of the metal, improve its wear resistance and fatigue performance, and regulate its microstructure. Bearing housings require quenching equipment for processing during the production process.

[0003] A high-frequency quenching device, as disclosed in Chinese Patent Publication No. CN202322418276.9, includes a base plate, a support frame, an electrical control cabinet, and a high-frequency coil. The support frame is mounted above the base plate, the electrical control cabinet is mounted above the support frame, and the high-frequency coil is fixed to the side of the electrical control cabinet. It also includes a lifting mechanism for lifting the workpiece, which is mounted on the base plate. This invention, by setting up a lifting mechanism, allows the lower end of the workpiece to be placed on the tip of a second chuck during use. Rotating a knob causes a threaded rod to rotate, which in turn lowers a fixing block. The fixing block, through a rotating column, lowers the first chuck, and the tip on the first chuck lowers to fix the upper end of the workpiece. This method of clamping and fixing the workpiece ensures a uniform gap between the workpiece and the high-frequency coil, effectively improving the quenching effect.

[0004] Some problems were found when using the existing high-frequency quenching device. First, the specifications of the bearing housings are different, and it is not convenient to replace the installation limit mechanism according to the model of the bearing housing. Second, during the quenching process of the bearing housing, although it is rapidly cooled to a lower temperature, it still cannot be picked up manually. Using tools to pick it up is not as flexible as using your hands. Components such as high-frequency coils will interfere with and affect the picking up of the bearing housing. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6This utility model provides a technical solution: a quenching device for bearing housing production, including a collection pool 1 and a bearing housing 9. A vertical support column 102 is fixedly connected to the rear of the collection pool 1. A limiting groove 103 is opened on the front of the vertical support column 102. A support arm 104 is slidably installed in the limiting groove 103. An electric telescopic rod 105 is fixedly connected in the limiting groove 103. The upper end of the electric telescopic rod 105 is fixedly connected to the support arm 104. A high-temperature resistant nozzle 7 is fixedly connected below the support arm 104. A high-frequency coil 8 is fixedly connected below the support arm 104 and on one side of the high-temperature resistant nozzle 7. A processing table 2 is slidably connected above the collection pool 1. An installation plate 3 is rotatably installed in the processing table 2 through a bearing. An installation slot 301 is opened in the installation plate 3. A bearing housing placement plate 5 is engaged in the installation slot 301. A placement slot 501 is opened on the bearing housing placement plate 5. The bearing housing 9 is placed in the placement slot 501. A plurality of drainage holes 502 are opened in the bearing housing placement plate 5.

[0024] In this embodiment, by placing the bearing housing 9 inside the placement slot 501, the processing table 2 is pushed to move the mounting plate 3 and the bearing housing placement plate 5, thereby moving the placed bearing housing 9 to below the high-frequency coil 8 and the high-temperature resistant nozzle 7, and to the maximum backward stroke of the processing table 2. Then, activating the electric telescopic rod 105 moves the support arm 104 downward, which in turn moves the high-temperature resistant nozzle 7 and the high-frequency coil 8 downward to insert them into the bearing housing 9. Figure 1 As shown, when the high-frequency coil 8 is activated, an alternating magnetic field is generated. At this time, the current is concentrated on the surface of the workpiece, forming eddy currents and rapidly heating up to about 750°C. The mounting plate 3 is mounted in the processing table 2 via a bearing rotation, allowing the mounting plate 3 to drive the bearing seat placement plate 5 to rotate freely. The rotation of the bearing seat placement plate 5 can drive the bearing seat 9 to rotate, so that the high-frequency coil 8 can uniformly heat the inner ring of the bearing seat 9. Then, clean water is sprayed onto the inner ring of the bearing seat 9 using the high-temperature resistant nozzle 7, causing the temperature of the inner ring of the bearing seat 9 to drop rapidly and form high-hardness cryptocrystalline martensite on the surface, thus completing the quenching operation of the workpiece. Then, the electric telescopic rod 105 is activated to drive the support arm 104 to move upward and reset. At this time, the processing table 2 can be pulled forward to move the bearing seat placement plate 5 away from the high-temperature resistant nozzle 7 and the high-frequency coil 8, avoiding their interference with the handling and placement of the bearing seat 9. At the same time, the high-frequency coil 8 is directly inserted into the inner ring of the bearing seat 9, which can perform high-frequency quenching on the inner ring of the bearing seat 9.

[0025] In order to achieve the purpose of conveying clean water to the high-temperature resistant spray pipe 7 for spraying, the device adopts the following technical solution: the upper part of the collection tank 1 is symmetrically fixed with a limiting slide rail 101, the two sides of the processing table 2 are symmetrically fixed with sliders 201, the sliders 201 slide with the limiting slide rail 101, the front of the processing table 2 is fixed with a displacement handle 202, the bottom of the collection tank 1 is fixed with a pump 106, the output end of the pump 106 is fixed with a conveying hose 107, the other end of the conveying hose 107 is connected to the support arm 104, the support arm 104 is provided with a channel, and the channel connects the high-temperature resistant spray pipe 7 and the support arm 104.

[0026] The processing table 2 is slidably installed above the collection tank 1 by sliding the limiting slide rail 101 and the slider 201. The processing table 2 can be directly pulled by the shift handle 202. A certain amount of cooling water is added to the collection tank 1. The pump 106 is started to deliver the water to the delivery hose 107. The delivery hose 107 delivers the water through the channel to the high-temperature resistant spray pipe 7. The surface of the high-temperature resistant spray pipe 7 is equipped with multiple nozzles, which can then be used to spray water onto the inner ring of the bearing seat 9 for rapid cooling.

[0027] To achieve the rotation of the bearing housing placement disk 5, the device employs the following technical solution: a fixing hole 302 is provided at the bottom of the mounting groove 301; a limiting post 503 is fixedly connected to the bottom of the bearing housing placement disk 5, and the limiting post 503 cooperates with the fixing hole 302; a limiting pin hole 303 is provided on the inner wall of the mounting groove 301; a limiting groove 6 is provided on the top of the bearing housing placement disk 5; a return spring 601 is fixedly connected in the limiting groove 6; and the other end of the return spring 601 is fixed... A limit pin 602 is connected, and the limit pin 602 and the limit pin hole 303 cooperate with each other. A displacement handle 603 is fixed on the limit pin 602. A motor bracket 203 is fixed on the bottom of the processing table 2. A rotary motor 4 is fixed on the motor bracket 203. A conical stop cap 402 is fixed on the output end of the rotary motor 4. An interference rod 403 is fixed on the outer wall of the conical stop cap 402. A drive protrusion 504 is fixed on the bottom of the bearing seat placement plate 5. The drive protrusion 504 and the interference rod 403 cooperate with each other.

[0028] By starting the rotary motor 4, the conical baffle 402 can be rotated. The rotation of the conical baffle 402 can drive the interference rod 403 to rotate. The driving protrusion 504 will interfere with the interference rod 403. In turn, the rotation of the interference rod 403 will drive the driving protrusion 504 to rotate synchronously. The rotation of the driving protrusion 504 can drive the bearing seat placement plate 5 to rotate, so that the bearing seat placement plate 5 can drive the bearing seat 9 to rotate slowly and uniformly. The drain hole 502 can drain the overflowing clean water into the collection tank 1. The conical baffle 402 is conical in shape, which can block the clean water. To prevent water from directly contacting the rotary motor 4, which is a waterproof motor, a small amount of water can be directly contacted. The bearing housing placement plate 5 is installed inside the mounting slot 301. At this time, the limiting pin 503 will be inserted into the fixing hole 302 to limit the bearing housing placement plate 5. The return spring 601 can provide a certain pushing force to the limiting pin 602. The limiting pin 602 will be pushed into the limiting pin hole 303, thereby fixing the bearing housing placement plate 5 inside the mounting slot 301. The displacement handle 603 can drive the limiting pin 602 to move.

[0029] The working principle and usage process of this utility model are as follows: When in use, the bearing seat 9 is placed inside the placement slot 501. Then, the processing table 2 is pushed to move the bearing seat 9 below the high-temperature resistant nozzle 7 and the high-frequency coil 8. Activating the electric telescopic rod 105 moves the support arm 104 downwards. The downward movement of the support arm 104 causes the high-temperature resistant nozzle 7 and the high-frequency coil 8 to insert into the bearing seat 9. Activating the rotary motor 4 causes the bearing seat placement plate 5 to rotate slowly and uniformly. The rotation of the bearing seat placement plate 5 causes the bearing seat 9 to rotate. Activating the high-frequency coil 8 evenly heats the inner ring of the bearing seat 9. Activating the pump 106 pumps clean water to the high-temperature resistant nozzle 7, causing the temperature of the inner ring of the bearing seat 9 to drop rapidly, forming high-hardness cryptocrystalline martensite on the surface, thus completing the quenching operation of the workpiece. Activating the electric telescopic rod 105 moves the support arm 104 upwards to reset it. At this time, the processing table 2 can be pulled forward to remove the processed bearing seat 9.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
