Description

Technical Field

[0001] This specification relates to one or more embodiments in the field of quenching and cooling technology, and more particularly to a heat treatment quenching and cooling device. Background Technology

[0002] In the field of mechanical manufacturing and heat treatment processes, gear discs are core transmission components, and their mechanical properties and dimensional stability directly determine the reliability, service life and operating accuracy of the entire machine. In order to improve production efficiency and reduce costs, batch quenching technology is widely used in the heat treatment processing of gear discs.

[0003] In traditional quenching tanks or spray cooling devices, multiple gear discs are usually fixed to tooling fixtures by stacking, stringing, or arranging in a planar manner.

[0004] Due to the limited spacing between adjacent gear disks, the high-temperature heat radiation and heat conduction effects are superimposed during the quenching heating process, forming a heat overlap zone on the gear contact surface or in the vicinity. The temperature in this zone is higher than that in other parts, resulting in a significant reduction in the heat exchange efficiency of the cooling medium at this location.

[0005] To address these issues, we designed a heat treatment quenching and cooling device. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a heat treatment quenching and cooling device to solve the above problems.

[0007] Based on the above objectives, this utility model provides a heat treatment quenching and cooling device, including a fixed plate, a limiting plate being snapped into the inner wall of the fixed plate, a base being fixedly installed in the middle section of the inner wall of the limiting plate, a motor being fixedly installed on the top of the base, a drive gear being fixedly installed on the top drive end of the motor, a rack one being meshed with the side wall of the drive gear, a left adjustment component being meshed with one side end of the rack, a rack two being meshed with the side of the drive gear away from the rack one, a right adjustment component being meshed with the side wall of the rack two, and a connecting column being rotatably installed at the bottom of both the left and right adjustment components.

[0008] Furthermore, another connecting column is rotatably installed at the connection point between connecting rod two and connecting rod three;

[0009] Each of the four connecting columns is fixedly installed with a retaining ring at its bottom, and a gear disc is engaged with the outer wall of the retaining ring.

[0010] Furthermore, the internal structure of the right adjustment component is the same as that of the left adjustment component, and the outer walls of the two connecting columns installed inside the left and right adjustment components are slidably connected to the inner wall of the limiting plate.

[0011] The outer walls of rack one and rack two are slidably connected to the inner wall of the fixing plate, and all the above components are made of high heat resistant materials.

[0012] Furthermore, the left adjustment assembly includes a driven gear meshing with one side wall of the rack. A connecting column is fixedly installed at the bottom of the driven gear. A connecting rod one is fixedly installed on the outer wall of the connecting column. A connecting rod two is rotatably installed at one end of the connecting rod one. A connecting rod three is rotatably installed at one side end of the connecting rod two. A connecting rod four is rotatably installed at one side end of the connecting rod three. The side end of the connecting rod four is rotatably connected to the outer wall of the connecting column.

[0013] As can be seen from the above, the beneficial effects provided by this utility model are:

[0014] 1. The motor drives the drive gear to rotate, which in turn causes rack one and rack two to move and extend relative to each other, thereby adjusting the position of the connecting posts in the left and right adjustment components. This changes the distance between the four connecting posts, thus reasonably adjusting the spacing of the gear discs engaged at the bottom and effectively avoiding the problem of heat overlap.

[0015] 2. It can simultaneously perform reasonable spacing adjustment and quenching cooling treatment on multiple gear disks to meet the needs of batch quenching processing. After adjusting the spacing, each gear disk can fully contact the cooling medium, which improves the heat exchange efficiency and helps to improve the heat treatment quality of the gear disk.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0023] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains.

[0024] Please see Figure 1-4This utility model provides a technical solution: a heat treatment quenching and cooling device, including a fixed plate 1. The fixed plate 1 has a limiting plate 2 attached to its inner wall. A base 10 is fixedly installed in the middle section of the inner wall of the limiting plate 2, and a motor 11 is fixedly installed on the top of the base 10. Installing the motor 11 on the base 10 in the middle section of the inner wall of the limiting plate 2 positions the motor 11 near the center of the device, which is beneficial for the balanced distribution of the overall weight and effectively reduces the impact of vibration generated by the motor 11 on the stability of the device. A drive gear 6 is fixedly installed on the top drive end of the motor 11. The drive gear 6 is located at the top drive end of the motor 11, and with the drive gear 6 as the center, racks 7 and 8 mesh on both sides respectively, forming a symmetrical layout structure. A gear and rack transmission method is adopted, where the motor 11 drives the drive gear 6 to rotate, and the drive gear 6 meshes with racks 7 and 8 respectively. The rotational motion of motor 11 is converted into linear motion of rack. Rack 7 is meshed with the side wall of drive gear 6, and left adjustment component 5 is meshed with the side end of rack 7. Rack 8 is meshed with the side of drive gear 6 away from rack 7, and right adjustment component 9 is meshed with the side wall of rack 8. The left adjustment component 5 and right adjustment component 9 are connected by connecting rod 501, connecting rod 502, connecting rod 503, connecting rod 504 and connecting column 3 to form a linkage structure. When driven gear 505 rotates and drives the bottom fixed connecting column 3 to rotate, the linkage structure can convert the rotational motion of connecting column 3 into the position adjustment motion of another connecting column 3, thereby adjusting the distance between the four connecting columns 3. The bottom of left adjustment component 5 and right adjustment component 9 are both rotatably mounted with connecting columns 3, so that the spacing of the gear disk 4 locked at the bottom can be precisely controlled. During the quenching and cooling process, the problem of heat overlap caused by the small spacing between adjacent gear disks 4 is avoided, ensuring that each gear disk 4 can be cooled in a relatively independent environment, thus improving the consistency and uniformity of the cooling effect.

[0025] See Figure 1-4The left-side adjusting assembly 5 includes a driven gear 505 meshing with the side wall of rack 7. This gear and rack transmission method can precisely convert the linear motion of rack 7 into the rotational motion of the driven gear 505. A connecting column 3 is fixedly mounted at the bottom of the driven gear 505. When the driven gear 505 drives the connecting column 3 to rotate, a connecting rod 501 is fixedly mounted on the outer wall of the connecting column 3. A connecting rod 502 is rotatably mounted at the end of the connecting rod 501. Connecting rod 3 503 is rotatably mounted on the side end of 2. Connecting rod 4 504 is rotatably mounted on the side end of connecting rod 3 503. The side end of connecting rod 4 504 is rotatably connected to the outer wall of connecting column 3. The connecting rod structure can convert the rotational motion of connecting column 3 into the position adjustment motion of another connecting column 3. It can not only realize the linear position adjustment of connecting column 3, but also realize the angle adjustment to a certain extent. This multi-dimensional adjustment function can more accurately control the posture of gear disk 4, so that gear disk 4 is in the optimal position and angle during the quenching and cooling process.

[0026] See Figure 1-4 The internal structure of the right adjustment component 9 is the same as that of the left adjustment component 5. When the motor 11 drives the rack 7 and rack 8 to move through the drive gear 6, based on this same structure, the two connecting columns 3 installed inside the left adjustment component 5 and the right adjustment component 9 can receive the adjustment action synchronously and symmetrically. At the same time, the outer walls of these two connecting columns 3 are slidably connected to the inner wall of the limiting plate 2. The sliding connection provides a stable guide for the movement of the connecting columns 3, further ensuring that the two adjustment components can accurately adjust the connecting columns 3, thereby accurately controlling the spacing and posture of the gear disks 4 locked at the bottom, ensuring that all gear disks 4 are in a uniform and consistent environment during the quenching and cooling process, and improving the consistency of the cooling effect.

[0027] See Figure 1-4 Each of the four connecting columns 3 has a retaining ring 301 fixedly installed at its bottom. The retaining ring 301 and the gear disk 4 are connected by a snap-fit ​​method. Compared with the traditional bolt connection, welding and other fixing methods, during the installation process, the gear disk 4 only needs to be aligned with the retaining ring 301 and a certain pressure is applied to complete the snap-fit ​​fixing. The operation is simpler and faster, shortens the installation time and improves the production efficiency. The gear disk 4 is snapped onto the outer wall of the retaining ring 301.

[0028] See Figure 1-4 The outer walls of rack 7 and rack 8 are slidably connected to the inner wall of the fixing plate 1. In this connection method, the fixing plate 1 provides a guide track for the movement of the rack. When the motor 11 drives rack 7 and rack 8 to move linearly through the drive gear 6, all the above components are made of high heat resistant materials. This characteristic, combined with the sliding connection method, can ensure that the rack moves smoothly along the predetermined direction without deviation, shaking or jamming.

[0029] Working principle: First, the gear disk 4, which needs to be quenched and cooled, is snapped onto the bottom of the four connecting posts 3 using retaining rings 301. Then, the motor 11 is started, and its drive end drives the drive gear 6, which is fixedly installed at the top, to rotate. Because the sidewalls of the drive gear 6 mesh with rack 7 and rack 8, which are slidably connected to the inner wall of the fixed plate 1, they will move relative to each other and extend. Rack 7 drives the driven gear 505 in the left adjustment assembly 5, which is meshed with its sidewall, to rotate, thereby driving the connecting post 3 fixed at the bottom of the driven gear 505 to rotate. Based on the linkage structure composed of connecting rod 501, connecting rod 502, connecting rod 503, connecting rod 504 and another connecting post 3 in the left adjustment assembly 5, the linkage structure of the entire left adjustment assembly 5 is moved, realizing the position adjustment of the other connecting post 3. At this point, due to the rotation of the two connecting posts 3, the relative surfaces of the gear disks 4 change, and the tooth groove surfaces of adjacent gear disks 4 face each other. At this time, since the connecting rod structure is fully extended, the connecting posts 3 no longer rotate, but the rack 7 is still moving, which will drive the left adjustment component 5 to move to the left as a whole. Since the internal structure of the right adjustment component 9 is the same as that of the left adjustment component 5, under the drive of the rack 8, the right adjustment component 9 also adjusts the position of the connecting posts 3 in the same way. At this time, the distance between the four connecting posts 3 changes, so that the spacing of the gear disks 4 locked at the bottom is reasonably adjusted, avoiding the problem of heat overlap. Finally, the gear disks 4 with the adjusted spacing are placed in the quenching and cooling device for cooling. The cooling medium can act more evenly on the gear disks 4, improving the heat exchange efficiency.
