Description

Technical Field

[0001] This utility model relates to a simple spray heat treatment device. Background Technology

[0002] Some crank gears require heat treatment at 900 degrees Celsius after casting. Following this heat treatment, a water mist heat treatment is necessary to improve surface strength. This involves suspending the crank gear in the air using a factory crane hook, and then spraying water mist onto it using a spraying device. However, this method is problematic because the crank gear, suspended by the crane hook and chain, is prone to irregular swaying during spraying. This prevents it from maintaining proper alignment with the spraying device, hindering the heat treatment process. Furthermore, the crank gear's position needs adjustment to ensure adequate contact between different parts and the water mist. Due to the high temperature of the crank gear, operators cannot use tools to approach and adjust its position; they must move the spraying device, making the operation cumbersome. To solve this technical problem, a support frame is currently installed under the crane hook, and the crank gear is placed vertically on the support frame. The position of the crank gear is adjusted by the support frame. However, the heat on the crank gear is quickly transferred to the support frame, which causes the crank gear temperature to drop too quickly and affects the spray heat treatment effect.

[0003] Therefore, it is necessary to improve the aforementioned technical issues, hence this case. Utility Model Content

[0004] This utility model addresses the problems existing in the prior art by providing a simple spray heat treatment device.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a simple spray heat treatment device, including a spraying device, a crane's lifting chain, a hook located below the lifting chain, and a support frame located directly in front of the spraying end of the spraying device. A horizontally mounted turntable is provided on the support frame. A vertically penetrating limiting slot is provided on the outer periphery of the turntable, extending radially to the center of the turntable. A vertically arranged connecting rod is fixed between the lower end of the lifting chain and the hook. The connecting rod passes through the limiting slot and is located at the center of the turntable, with a rectangular cross-section. A rotating assembly for driving the turntable to rotate is also provided on the support frame, causing the connecting rod to rotate when the turntable rotates.

[0006] Furthermore, the turntable is circular in shape, and an external toothed portion is coaxially provided on the outer circumference of the turntable; the rotating assembly includes a horizontally arranged rotating gear, which meshes with the external toothed portion, and the rotating gear is driven to rotate by a rotating motor installed at the bottom of the support frame.

[0007] Furthermore, the support frame is provided with a clearance slot corresponding to the position of the limiting slot. The clearance slot has the same shape as the limiting slot, and the clearance slot facilitates the passage of the connecting rod.

[0008] Furthermore, the top of the support frame is provided with an arc-shaped groove directly below the turntable. The arc-shaped groove is coaxial with the turntable, and multiple rolling columns are distributed inside the arc-shaped groove. The rolling columns are horizontally arranged and can rotate within the arc-shaped groove. The bottom of the turntable is in contact with the outer circumferential surface of the multiple rolling columns, and the turntable forms a rolling engagement with the rolling columns when it rotates.

[0009] Furthermore, the length of the limiting slot is greater than the radius of the turntable.

[0010] Furthermore, the turntable is coaxially provided with an arc-shaped sliding groove, which runs vertically through the turntable; a vertically arranged sliding guide rod is fixed on the support frame, which passes through the arc-shaped sliding groove and slides in cooperation with the arc-shaped sliding groove.

Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] like Figures 1-4As shown, this utility model discloses a simple spray heat treatment device, including a spraying device 1, a crane lifting chain 2, a hook 3 located below the lifting chain 2, and a support frame 4 located directly in front of the spraying end of the spraying device 1. A horizontally mounted turntable 5 is mounted on the support frame 4. A vertically penetrating limiting slot 6 is provided on the outer periphery of the turntable 5, extending radially to the center of the turntable 5. The limiting slot 6 has a rectangular cross-section. A vertically arranged connecting rod 7 is fixed between the lower end of the lifting chain 2 and the hook 3. The connecting rod 7 passes through the limiting slot 6 and is located at the center of the turntable 5. The connecting rod 7 has a rectangular cross-section. A rotating assembly for driving the turntable 5 to rotate is also provided on the support frame 4. When the turntable 5 rotates, it drives the connecting rod 7 to rotate. During operation, the overhead crane hooks onto the crank gear 19. The crane moves the crank gear close to the support frame, bringing the connecting rod near the limiting slot of the turntable. The crane is then controlled to guide the connecting rod into the limiting slot and move it to the bottom of the slot, at which point the connecting rod is at the center of the turntable. The crane stops moving, and the spraying device sprays water mist towards the crank gear. When the crank gear needs to be rotated for adjustment, the rotating assembly drives the turntable to rotate. Since both the limiting slot and the connecting rod have rectangular cross-sections, the rotation of the turntable drives the connecting rod to rotate. The connecting rod then drives the hook and the crank gear mounted on the hook to rotate, allowing for rotational adjustment of the crank gear's position to ensure sufficient contact between different parts of the crank gear and the water mist.

[0024] In this embodiment, the turntable 5 is circular, and its outer circumference is coaxially provided with external teeth distributed in an arc shape. The rotating assembly includes a horizontally arranged rotating gear 8, which meshes with the external teeth. The rotating gear 8 is driven to rotate by a rotating motor 9 mounted at the bottom of the support frame 4. The rotating motor drives the rotating gear to rotate, and the rotating gear drives the turntable to rotate through the external teeth. The rotation direction of the turntable can be adjusted by rotating the rotating motor in both forward and reverse directions. Furthermore, the control switch of the rotating motor is located at a distance from the support frame in the factory, facilitating manual control of the rotating motor's start, stop, and forward / reverse rotation. It should be noted that in actual spray heat treatment of crank gears, the rotation angle of the crank gear is only approximate, with no specific angle requirement. It is usually adjusted by on-site operators based on experience, which is known to those skilled in the art. Therefore, this application is merely for the purpose of achieving crank gear rotation.

[0025] In this embodiment, the support frame 4 is provided with a clearance slot 10 corresponding to the position of the limiting slot 6. The clearance slot 10 has the same shape as the limiting slot 6. The clearance slot 10 facilitates the passage of the connecting rod 7. That is, when in use, the connecting rod extends into both the clearance slot and the limiting slot at the same time and passes through the clearance slot and the limiting slot vertically.

[0026] In this embodiment, the top of the support frame 4 is provided with an arc-shaped groove 11 directly below the turntable 5. The arc-shaped groove 11 is coaxially arranged with the turntable 5, and multiple rolling columns 12 are distributed within the arc-shaped groove 11. The rolling columns 12 are horizontally arranged and can rotate within the arc-shaped groove 11, with their upper ends extending out of the arc-shaped groove. The bottom of the turntable 5 contacts the outer circumferential surface of the multiple rolling columns 12, and the turntable 5 forms a rolling engagement with the rolling columns 12 when it rotates. The multiple rolling columns thus achieve a rotational engagement between the turntable and the support frame.

[0027] In this embodiment, in order to facilitate the connecting rod to move to the center of the turntable within the limiting slot, the length of the limiting slot 6 is greater than the radius of the turntable 5.

[0028] In this embodiment, a circular arc-shaped groove 13 is coaxially arranged on the turntable 5, and the circular arc-shaped groove 13 extends vertically. A vertically arranged sliding guide rod 14 is fixed on the support frame 4, and the sliding guide rod 14 passes through the circular arc-shaped groove 13 and slides in cooperation with the circular arc-shaped groove 13. When the turntable rotates, the sliding guide rod slides in cooperation with the circular arc-shaped groove, and the sliding guide rod plays a certain guiding role in the rotation of the turntable.

[0029] In this embodiment, to prevent the turntable from deviating from its position, the top of the support frame 4 is provided with a pair of left and right opposing limiting blocks 15. The limiting blocks 15 are horizontal U-shaped, and the left and right ends of the turntable 5 extend into the limiting blocks 15 respectively, using a pair of limiting blocks to limit the position from the left and right ends.

[0030] In this embodiment, the support frame 4 is in the shape of a rectangular plate, and vertical support columns 16 are fixed at the top corners of the bottom four sides of the support frame 4. The vertical support columns support the support frame at a certain height off the ground.

[0031] In this embodiment, the spraying device 1 includes an axial flow fan 17, the outlet of which faces the support frame 4. A water mist nozzle 18 is arranged on the right side in front of the outlet of the axial flow fan 17, and the water mist output port of the water mist nozzle 18 is perpendicular to the outlet of the axial flow fan 17. The water mist nozzle outputs water mist, and the axial flow fan blows the water mist to contact the crank gear.

[0032] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then, unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws), or a non-detachable fixed connection (e.g., riveting, welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured using a casting process) (except where it is obviously impossible to use an integral forming process).

[0033] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in this utility model above include states or shapes that are similar to, close to, or approximate with them.

[0034] Any component provided by this utility model can be assembled from multiple individual components, or it can be a single component manufactured by a one-piece molding process.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
