Description

Technical Field

[0001] This invention relates to the field of camshaft machining technology, and in particular to a high-efficiency camshaft quenching device. Background Technology

[0002] High-frequency quenching is a metal heat treatment method that involves placing the workpiece inside an inductor, typically a hollow copper tube that receives medium-frequency or high-frequency alternating current (1000-300000Hz or higher). This induces a current of the same frequency within the workpiece. This induced current is unevenly distributed, strong at the surface and weak at the interior, approaching zero at the core. Utilizing this skin effect, the workpiece surface is rapidly heated, reaching 800-1000℃ within seconds, while the core temperature rises only slightly, followed by rapid cooling. Quenching can induce martensitic structures in materials such as steel, thereby increasing their hardness and strength, as well as improving their wear resistance.

[0003] Chinese invention patent [Publication No.: CN114561521A] discloses a high-frequency quenching device and quenching process for motor shafts, including a conveyor belt and a worktable disposed above the conveyor belt. Several placement seats are evenly arranged on the conveyor belt. A clamping mechanism is slidably installed on the worktable. The clamping mechanism includes a power unit, a support component, a clamping component, and a locking component. The power unit is disposed on the worktable, the support component is slidably disposed on the worktable, the clamping component is disposed on the worktable and the support component, and the locking component is disposed on the clamping component and the worktable. A high-frequency sensor is disposed at the bottom of the worktable, and a water pipe is disposed on one side of the worktable next to the high-frequency sensor.

[0004] Because the clamping mechanism of this device needs to be reset after clamping the camshaft for quenching before it can be clamped on the conveyor belt, the working efficiency is low. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a high-efficiency camshaft quenching device to solve the problem in the prior art that after the clamping mechanism clamps the camshaft for quenching, it needs to be reset before the camshaft can be clamped on the conveyor belt, resulting in low working efficiency.

[0006] The present invention solves the above-mentioned technical problems through the following technical means:

[0017] Furthermore, the water tank is equipped with a water storage tank, and the bottom of the water storage tank is provided with several filter tanks. The water storage tank is connected to the water tank through the filter tanks.

[0018] Furthermore, the conveyor belt is provided with several support units, each support unit including two support components. One of the two support components is used to place the unquenched camshaft, and the other support component is used to support the quenched camshaft. The camshafts to be quenched on adjacent support units on the same conveyor belt are placed in opposite positions.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] like Figures 1-5 As shown, a high-efficiency camshaft quenching device of the present invention includes a worktable 1, a conveying mechanism 2, a quenching mechanism 3, a clamping mechanism, and a power mechanism 7, wherein...

[0044] The conveying mechanism 2 is located below the workbench 1 and is used to convey the camshaft 10. Specifically, the conveying mechanism 2 includes a first conveyor belt 21 and a second conveyor belt 22. Both the first conveyor belt 21 and the second conveyor belt 22 are located below the workbench 1, and the conveying directions of the first conveyor belt 21 and the second conveyor belt 22 are opposite.

[0045] The quenching mechanism 3 is located below the workbench 1 and between the first conveyor belt 21 and the second conveyor belt 22. It is used to quench the camshaft 10. Specifically, the quenching mechanism 3 includes two sets of quenching components and a water tank 31. The quenching components include a coil 32, which is a high-frequency quenching coil. The camshaft 10 is quenched when it passes through the coil 32. A mounting bracket 321 is provided at the bottom of the coil 32 and is fixedly installed on the water tank 31. Water pipes 33 are provided on both sides of the coil 32. A water pump is provided in the water tank 31, and the water pipes 33 are connected to the water pump. When the water pump is working, it can spray the cooling water in the water tank 31 onto the camshaft 10 through the water pipes 33 to cool the camshaft 10. The water tank 31 is equipped with a water storage tank 311. Several filter tanks 312 are opened at the bottom of the water storage tank 311. The water storage tank 311 is connected to the water tank 31 through the filter tanks 312. The water sprayed by the water pipe 33 is filtered through the filter tanks 312 and then returned to the water tank 31, realizing water recycling.

[0046] In this embodiment, two clamping mechanisms are provided: a first clamping mechanism 41 and a second clamping mechanism 42, with opposite moving directions. These correspond to the two sets of quenching components. For example, when the first clamping mechanism 41 clamps the camshaft 10 on the first conveyor belt 21 for quenching, the second clamping mechanism 42 clamps the camshaft 10 on the second conveyor belt 22 for quenching. When the first clamping mechanism 41 places the quenched camshaft 10 on the second conveyor belt 22, the second clamping mechanism 42 places the quenched camshaft 10 on the first conveyor belt 21. After the first and second conveyor belts 21 and 22 have transported the quenched camshaft 10 away, the first clamping mechanism 41 clamps the unquenched camshaft 10 on the second conveyor belt 22 for quenching, and the second clamping mechanism 42 clamps the unquenched camshaft 10 on the first conveyor belt 21 for quenching, effectively improving quenching efficiency.

[0047] Since the first clamping mechanism 41 and the second clamping mechanism 42 have the same structure, the following detailed description will take the first clamping mechanism 41 as an example:

[0048] The first clamping mechanism 41 includes: a clamping unit 5 and a driving unit 6, wherein...

[0049] The clamping unit 5 is used to clamp and move the camshaft 10. Specifically, the clamping unit 5 includes a mounting plate 51 and a clamping assembly. A mounting groove 11 is provided on the worktable 1 corresponding to the position of the mounting plate 51. A connecting plate 52 is provided on the mounting plate 51 and is slidably disposed in the mounting groove 11, so that the mounting plate 51 is slidably mounted on the worktable 1. The clamping assembly is disposed at the bottom of the mounting plate 51. The movement of the mounting plate 51 can drive the clamping assembly to move. The clamping assembly is used to clamp the camshaft 10. In this embodiment, the clamping assembly includes a first center 53 and a second center 54. Both the first center 53 and the second center 54 are provided with mounting ears 55, and both mounting ears 55 are connected to the drive unit 6 for transmission.

[0050] In this embodiment, a rotary motor 56 is fixedly installed on the mounting ear 55 corresponding to the first tip 53. The output shaft of the rotary motor 56 is fixedly connected to the first tip 53. When the camshaft 10 passes through the coil 32, the rotary motor 56 works, driving the first tip 53 to rotate, thereby driving the camshaft 10 clamped between the first tip 53 and the second tip 54 to rotate, so that the camshaft 10 is uniformly quenched.

[0051] The drive unit 6 includes a drive motor 61 and a double-ended screw 62. The double-ended screw 62 is rotatably mounted on the bottom of the mounting plate 51. The output shaft of the drive motor 61 is fixedly connected to the double-ended screw 62. Two mounting ears 55 are threaded to both ends of the double-ended screw 62. When the drive unit 6 operates, it moves the two mounting ears 55, which in turn drive the first center 53 and the second center 54 to clamp or release the clamped camshaft 10.

[0052] The mounting plates 51 of both the first clamping mechanism 41 and the second clamping mechanism 42 are connected to the power mechanism 7 via a transmission connection. The power mechanism 7 includes a servo motor 71 and a transmission gear 72. The servo motor 71 is fixedly mounted on the worktable 1. A drive plate 521 is provided on the connecting plate 52, and a rack 522 is provided on the drive plate 521. The rack 522 meshes with the transmission gear 72. When the servo motor 71 is working, it can simultaneously drive the first clamping mechanism 41 and the second clamping mechanism 42 to move synchronously, eliminating the need to configure a power source for each clamping mechanism.

[0053] In this embodiment, the first conveyor belt 21 and the second conveyor belt 22 have the same structure. The following is a detailed description using the first conveyor belt 21 as an example:

[0054] A plurality of support units 8 are provided on the first conveyor belt 21. Each support unit 8 includes two support components, each including a support block 81. Two support blocks 81 are provided, one on each side of the first conveyor belt 21. A column 211 is provided on the first conveyor belt 21 at a position corresponding to the support block 81. A through hole 811 is provided on the support block 81, through which the support block 81 is slidably mounted on the column 211. A first limiting ring 212 is provided at the top of the column 211, and a second limiting ring 812 is provided at the bottom of the through hole 811. The first limiting ring 212 and the second limiting ring 812 are used to limit the highest position of the support block 81, preventing the support block 81 from detaching from the column 211. A third elastic element 213 is sleeved on the column 211. One end of the third elastic element 213 abuts against the first conveyor belt 21, and the other end abuts against the support block 81. The third elastic element 213 is a compression spring, used to keep the support block 81 in the highest position.

[0055] The support block 81 has a support groove 813, in which the shaft of the camshaft 10 can be placed. By supporting the shaft of the camshaft 10, the axis of the camshaft 10 can be determined so that the first tip 53 and the second tip 54 can be clamped on the axis of the camshaft 10. The support block 81 has a first inclined surface 814 and a second inclined surface 815 symmetrically arranged on both sides. When the first tip 53 and the second tip 54 clamp the camshaft 10 and move, when the cam of the camshaft 10 abuts against the first inclined surface 814 or the second inclined surface 815, it can drive the support block 81 to move downward, so that the support block 81 can be released from the obstruction of the camshaft 10, so that the first tip 53 and the second tip 54 can clamp the camshaft 10 smoothly through the support block 81.

[0056] It should be noted that in the two support components of support unit 8, only one support component holds the camshaft 10 to be quenched, while the other support component is used to support the already quenched camshaft 10. Furthermore, the positions of the camshafts 10 to be quenched on adjacent support units 8 on the first conveyor belt 21 are opposite; that is, the camshafts 10 to be quenched in the preceding support unit 8 are placed on the support component closer to the conveying direction, while the camshafts 10 to be quenched in the following support unit 8 are placed on the support component farther from the conveying direction. The second conveyor belt 22 follows the same principle as the first conveyor belt 21. If the camshafts 10 to be quenched are placed on the support components on the first conveyor belt 21, then the corresponding support components on the second conveyor belt 22 do not hold the camshafts 10 to be quenched.

[0057] In this embodiment, a high-efficiency camshaft quenching device operates as follows: Since the working principles of the first clamping mechanism 41 and the second clamping mechanism 42 are the same, subsequent steps will be explained in detail using the working principle of the first clamping mechanism 41 as an example:

[0058] First, the drive motor 61 of the first clamping mechanism 41 operates, driving the first tip 53 and the second tip 54 to move closer together via the double-headed screw 62 and the mounting ear 55, thus clamping the camshaft 10 on the first conveyor belt 21 support assembly securely.

[0059] Subsequently, the servo motor 71 operates, driving the mounting plate 51 of the first clamping mechanism 41 to move through the transmission gear 72 and rack 522. The mounting plate 51 uses the clamping assembly to allow the camshaft 10 to be quenched through the coil 32.

[0060] After quenching, the drive motor 61 of the first clamping mechanism 41 operates, driving the first center 53 and the second center 54 to move away from each other via the double-ended screw 62 and the mounting lug 55, thus placing the quenched camshaft 10 onto the support assembly of the second conveyor belt 22.

[0061] After the second conveyor belt 22 transports the quenched camshaft 10 away, the drive motor 61 of the first clamping mechanism 41 works, driving the first tip 53 and the second tip 54 to move closer together through the double-headed screw 62 and the mounting lug 55, clamping the camshaft 10 on the support assembly of the second conveyor belt 22 firmly. Under the drive of the servo motor 71, the mounting plate 51 moves to drive the camshaft 10 to be quenched, realizing the cyclic operation.

[0062] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications and substitutions should be covered within the scope of the claims of the present invention. Technical aspects, shapes, and structures not described in detail in this invention are all well-known technologies.
