Description

Technical Field

[0001] This utility model relates to the field of heat treatment technology, and more specifically, to a device for preventing deformation during product heat treatment. Background Technology

[0002] Heat treatment refers to a metal heat treatment process in which materials are heated, held at a certain temperature, and cooled in a solid state to obtain the desired structure and properties. Metal heat treatment processes can be broadly classified into three categories: overall heat treatment, surface heat treatment, and chemical heat treatment. Each category can be further divided into several different heat treatment processes according to the different heating media, heating temperatures, and cooling methods.

[0003] Chinese patent disclosure CN202121794908.6 discloses a heat treatment anti-deformation tooling, relating to the field of heat treatment technology. It includes a baffle and a sliding plate. Side plates are movably connected to both sides of the baffle. The sliding plate is slidably disposed between the two side plates. A base plate is disposed between the two side plates, located at the bottom of the side plates. The sliding plate is slidably disposed on the base plate. A crossbeam is disposed between the two side plates. A locking mechanism is disposed between the sliding plate and the crossbeam, used to control the sliding and locking of the sliding plate. This heat treatment anti-deformation fixture, through the cooperation of a baffle, sliding plate, side plate, crossbeam, base plate, and locking mechanism, allows for adjustment of the distance between the sliding plate and side plate during use. This adjustment can be tailored to different parts being processed, protecting them from deformation and improving the practicality of the anti-deformation fixture. However, certain problems remain. While the device uses a sliding plate and baffle to fix the processed parts and prevent deformation, and uses limiting plates and limiting slots to position the sliding plate (multiple equally spaced limiting slots), this structure, although capable of adjusting and locking the sliding plate's position, has gaps between the limiting slots. These gaps may prevent the adjusted sliding plate from fully conforming to the processed parts. Therefore, we provide a product heat treatment anti-deformation device. Utility Model Content

[0004] The purpose of this utility model is to provide a device for preventing product deformation during heat treatment, so as to solve the problems mentioned in the background art above:

[0005] Some existing devices use a sliding plate and a baffle to fix the workpiece to prevent deformation. The sliding plate is positioned by a limiting plate and a limiting slot. Multiple limiting slots are set at equal intervals. Although this structure can adjust and lock the position of the sliding plate, there is a certain gap between the limiting slots. This gap may cause the adjusted sliding plate to not fit completely against the workpiece.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A heat treatment anti-deformation device for products includes a side plate, a baffle fixedly connected to the outside of the side plate, a sleeve rotatably connected to the inside of the baffle, and six grooves symmetrically distributed on the inside of the sleeve near the baffle. A sliding plate is slidably connected to the inside of each groove, and an adjusting plate is slidably connected to the outside of the sliding plate. An inclined groove is formed inside the adjusting plate, and a sliding rod is slidably connected to the inside of the inclined groove. The sliding rod is fixedly connected to the sliding plate, and a threaded rod is fixedly connected to the outside of the sliding plate. A sliding plate is sleeved on the outside of the threaded rod, and the sliding plate is threadedly connected to the threaded rod.

[0008] Preferably, the cross-section of the threaded rod is a fan-shaped structure.

[0009] Preferably, the adjusting plate is internally threaded with a positioning screw, and a knob is fixedly connected to the outer end of the positioning screw away from the sleeve. The sleeve has a positioning hole inside, which is used in conjunction with the positioning screw.

[0010] Preferably, the sleeve has a first limiting groove inside, and a first limiting rod is slidably connected inside the first limiting groove. The first limiting rod is fixedly connected to the adjusting plate.

[0011] Preferably, the cross-sections of the first limiting groove and the first limiting rod are both T-shaped structures.

[0012] Preferably, a second limiting groove is provided on the lower surface of the sliding plate, and a second limiting rod is slidably connected inside the second limiting groove, and the second limiting rod is fixedly connected to the baffle.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The rotating adjustment plate presses the sliding rod through the inclined groove, causing the sliding rod to move the slide plate. The slide plate then moves the threaded rod, which retracts inward and separates from the sliding plate. This allows for direct movement of the sliding plate. When the sliding plate moves close to the part to be processed, the rotating adjustment plate controls the threaded rod to expand outward, allowing it to engage with the sliding plate. The six expanded threaded rods combine to form a lead screw. At this point, the user can slightly rotate the sleeve to rotate the lead screw, which in turn drives the sliding plate to engage with the part being processed, thus fixing the part in place. Because the lead screw has multiple adjustment positions, there will be no situation where the sliding plate cannot engage with the part being processed, making it more adaptable.

[0021] 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.

[0022] Please see Figures 1 to 5 A heat treatment anti-deformation device for products includes a side plate 1, a baffle 2 fixedly connected to the outside of the side plate 1, a sleeve 3 rotatably connected to the inside of the baffle 2, and six grooves 4 symmetrically distributed on the inside of the sleeve 3 near the baffle 2. A sliding plate 5 is slidably connected inside the grooves 4, and an adjusting plate 6 is slidably connected to the outside of the sliding plate 5. An inclined groove 7 is provided inside the adjusting plate 6. When the adjusting plate 6 rotates, it can squeeze a sliding rod 8 through the inclined groove 7, causing the sliding rod 8 to drive the sliding plate 5 to move. The sliding plate 5 then adjusts the position of a threaded rod 9. After the threaded rod 9 is disengaged from the sliding plate 10, the position of the sliding plate 10 can be directly adjusted, which is more convenient and faster. The sliding rod 8 is slidably connected inside the inclined groove 7 and fixedly connected to the sliding plate 5. A threaded rod 9 is fixedly connected to the outside of the sliding plate 5, and a sliding plate 10 is sleeved on the outside of the threaded rod 9. The sliding plate 10 is threadedly connected to the threaded rod 9. When the threaded rod 9 rotates, it can drive the sliding plate 10 to move, thereby adjusting the position of the sliding plate 10, and fixing the processed parts in conjunction with the baffle 2.

[0023] Furthermore, the cross-section of the threaded rod 9 is a fan-shaped structure. Six threaded rods 9 can be assembled into a complete screw rod after being spread out. When the screw rod rotates, it can drive the sliding plate 10 to move. Compared with limiting the sliding plate 10 by limiting the limit plate and limiting slot, adjusting the position of the sliding plate 10 by the screw rod is more adaptable and can adjust more positions.

[0024] Furthermore, the adjusting plate 6 is internally threaded with a positioning screw 11. A knob 12 is fixedly connected to the outer end of the positioning screw 11 away from the sleeve 3. The sleeve 3 has a positioning hole 13 inside. The positioning hole 13 works in conjunction with the positioning screw 11. After the six threaded rods 9 are spread out, the positioning screw 11 can engage with the positioning hole 13. The positioning screw 11, in conjunction with the positioning hole 13, locks the position of the adjusting plate 6, thereby locking the position of the spread threaded rods 9.

[0025] Furthermore, a first limiting groove 14 is provided inside the sleeve 3, and a first limiting rod 15 is slidably connected inside the first limiting groove 14. The first limiting rod 15 is fixedly connected to the adjusting plate 6. Three sets of the first limiting groove 14 and the first limiting rod 15 are symmetrically arranged. The first limiting groove 14 and the first limiting rod 15 limit the adjustment plate 6 and the sleeve 3, so that the adjusting plate 6 and the sleeve 3 fit together, and also prevent the sliding plate 5 from separating from the groove 4.

[0026] Furthermore, the cross-sections of the first limiting groove 14 and the first limiting rod 15 are both T-shaped structures. The T-shaped structure ensures that the first limiting rod 15 will not detach from the first limiting groove 14, thereby ensuring that the adjusting plate 6 will not separate from the sleeve 3.

[0027] Furthermore, a second limiting groove 16 is provided on the lower surface of the sliding plate 10, and a second limiting rod 17 is slidably connected inside the second limiting groove 16. The second limiting rod 17 is fixedly connected to the baffle 2. The sliding plate 10 is limited by the second limiting groove 16 and the second limiting rod 17. When the threaded rod 9 rotates, it can drive the sliding plate 10 to move back and forth, and cooperate with the baffle 2 to fix the processed parts.

[0028] The steps for using this utility model are as follows: When using the heat treatment anti-deformation device, the user turns knob 12 to separate the positioning screw 11 from the positioning hole 13, allowing the adjusting plate 6 to rotate. The rotating adjusting plate 6 presses against the slide rod 8 through the inclined groove 7, causing the slide rod 8 to move the sliding plate 5. The sliding plate 5 then moves the threaded rod 9, thereby adjusting the position of the threaded rod 9 by rotating the adjusting plate 6. This allows all six threaded rods 9 to simultaneously expand outward or contract inward. When the threaded rod 9 contracts inward, it separates from the sliding plate 10, at which point... The position of the sliding plate 10 can be moved directly. When the sliding plate 10 moves close to the part to be processed, the adjusting plate 6 is rotated to control the threaded rod 9 to open outward, so that the threaded rod 9 and the sliding plate 10 are combined. The six threaded rods 9 that are opened are combined to form a lead screw. At this time, the user can drive the lead screw to rotate by slightly rotating the sleeve 3. The lead screw drives the sliding plate 10 to fit with the part to be processed, thereby fixing the part to be processed. Since there are many adjustment positions of the lead screw, there will be no situation where the sliding plate 10 cannot fit with the part to be processed, making it more adaptable.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
