Description

Technical Field

[0001] This utility model relates to the field of heat treatment, and in particular to a lifting device for high-stability heat treatment. Background Technology

[0002] A heat treatment lifting fixture is a lifting frame used for heat treatment of workpieces such as magnetic cores. In use, the workpieces are placed inside the frame and then placed into the heat treatment chamber by a crane for calcination.

[0003] Existing high-stability heat treatment lifting fixtures cannot adaptively adjust the size of the holes in the bottom tray during use, making them unsuitable for workpieces of various sizes. Smaller workpieces may fall through the tray holes, while larger workpieces may experience uneven heating at the bottom.

[0004] Therefore, the existing high-stability heat treatment lifting fixtures cannot adaptively adjust the size of the holes in the bottom tray, making them unsuitable for workpieces of various sizes. Smaller workpieces may fall through the tray holes, while larger workpieces may experience uneven heating at the bottom. A new high-stability heat treatment lifting fixture can be designed. By setting a lever, moving the lever causes the perforated plate to rotate inside the base plate. This allows adjustment of the opening area of ​​the through holes on the base plate and cover plate surfaces. As the perforated plate rotates, a limiting rod on the right side slides within a limiting groove at the bottom of the slot. The limiting groove restricts the sliding direction of the limiting rod, thereby improving the stability of the perforated plate rotation. This allows for adjustment of the through hole area to suit workpieces of different sizes. Utility Model Content

[0005] To overcome the problem that the existing high-stability heat treatment lifting tool cannot adaptively adjust the size of the holes in the bottom tray during use, making it unsuitable for workpieces of various sizes, smaller workpieces will fall through the tray holes, while larger workpieces will experience uneven heating at the bottom.

[0006] The technical solution of this utility model is as follows: a high-stability heat treatment lifting device, including a base plate; it also includes a cover plate, through holes, slots, limiting slots, a perforated plate, a lever, and a limiting rod. The upper surface of the base plate is provided with a cover plate, and several through holes are opened through the upper surface of the cover plate and the bottom of the inner surface of the base plate. A slot is opened on the right side surface of the base plate, and a limiting slot is provided at the bottom of the inner surface of the slot. A perforated plate is rotatably connected to the bottom of the inner surface of the base plate, and the upper surface of the perforated plate is rotatably connected to the bottom surface of the cover plate. A lever is provided on the right side surface of the perforated plate, and a limiting rod is provided on the right side surface of the perforated plate below the lever. The limiting rod is slidably connected to the limiting slot.

[0007] Preferably, by setting a lever, the perforated plate can be rotated inside the base plate when the lever is moved. This allows the opening area of ​​the through holes on the base plate and cover plate to be adjusted. When the perforated plate rotates, the limiting rod on the right side of the perforated plate slides inside the limiting groove at the bottom of the slot. The limiting groove restricts the sliding direction of the limiting rod, thereby improving the stability of the perforated plate rotation. This allows for adjustment of the through hole area to suit workpieces of different sizes. This solves the problem that the existing high-stability heat treatment lifting fixture cannot adaptively adjust the size of the holes in the bottom tray, making it unsuitable for workpieces of various sizes. Smaller workpieces may fall through the tray holes, while larger workpieces may experience uneven heating at the bottom.

[0008] Preferably, one end of a screw is rotatably connected to the middle of the upper surface of the cover plate, a movable seat is threaded through the outer surface of the screw, a pressure plate is provided on the outer surface of the movable seat, and a top cover is provided on the top of the screw.

[0009] Preferably, the upper surface of the cover plate is provided with one end of a slide rod on both the left and right sides of the screw, and the other end of the slide rod passes through the movable seat and is connected to the bottom surface of the top cover.

[0010] Preferably, a driven gear is rotatably connected to the middle position of the upper surface of the top cover, the top shaft of the screw passes through the top cover and is connected to the bottom surface of the driven gear, and a driving gear is rotatably connected to the front side of the upper surface of the top cover, and the driving gear meshes with the driven gear.

[0012] Preferably, the top surface edge of the top cover is provided with four circumferentially distributed mounting seats, and the top surface of the mounting seats is provided with lifting rings.

[0013] Preferably, limit frames are provided at the edges of the upper surfaces of both the cover plate and the pressure plate.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting a lever, the perforated plate can be rotated inside the base plate when the lever is moved. This allows adjustment of the opening area of ​​the through holes on the base plate and cover plate surfaces. When the perforated plate rotates, the limiting rod on the right side of the perforated plate slides inside the limiting groove at the bottom of the slot. The limiting groove restricts the sliding direction of the limiting rod, thereby improving the stability of the perforated plate rotation. This allows for adjustment of the through hole area to suit workpieces of different sizes. This solves the problem that existing high-stability heat treatment lifting tools cannot adaptively adjust the size of the holes in the bottom tray, making them unsuitable for workpieces of various sizes. Smaller workpieces may fall through the tray holes, while larger workpieces may experience uneven heating at the bottom. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4This utility model provides an embodiment of a high-stability heat treatment lifting fixture, including a base plate 1; it also includes a cover plate 2, through holes 3, slots 4, limiting grooves 5, a perforated plate 6, a lever 7, and a limiting rod 8. The cover plate 2 is provided on the upper surface of the base plate 1. Several through holes 3 are provided through the upper surface of the cover plate 2 and the bottom of the inner surface of the base plate 1. A slot 4 is provided on the right side surface of the base plate 1. A limiting groove 5 is provided at the bottom of the inner surface of the slot 4. A perforated plate 6 is rotatably connected to the bottom of the inner surface of the base plate 1. The upper surface of the perforated plate 6 is rotatably connected to the bottom surface of the cover plate 2. A lever 7 is provided on the right side surface of the perforated plate 6. A limiting rod 8 is provided on the right side surface of the perforated plate 6 below the lever 7. The limiting rod 8 is slidably connected to the limiting groove 5. By setting the lever 7, the lifting fixture... When the lever 7 is turned, the perforated plate 6 can rotate inside the base plate 1. This allows the opening area of ​​the through holes 3 on the surfaces of the base plate 1 and the cover plate 2 to be adjusted via the perforated plate 6. When the perforated plate 6 rotates, the limiting rod 8 on the right side of the perforated plate 6 slides inside the limiting groove 5 at the bottom of the slot 4. The limiting groove 5 restricts the sliding direction of the limiting rod 8, thereby improving the stability of the rotation of the perforated plate 6. This allows for the adjustment of the area of ​​the through holes 3 to suit workpieces of different sizes. This solves the problem that the existing high-stability heat treatment lifting fixture cannot adaptively adjust the size of the holes in the bottom tray, making it unsuitable for workpieces of various sizes. Smaller workpieces will fall through the holes in the tray, while larger workpieces will experience uneven heating at the bottom.

[0023] Please see Figures 1-3 In this embodiment, a screw 9 is rotatably connected to the middle of the upper surface of the cover plate 2. A movable seat 10 is threadedly connected to the outer surface of the screw 9. A pressure plate 11 is provided on the outer surface of the movable seat 10. A top cover 12 is provided on the top of the screw 9. By setting the screw 9, when the screw 9 rotates, it can drive the movable seat 10, which is threaded with it, to move up and down. The movable seat 10 can drive the pressure plate 11 to move synchronously, thereby pressing the top of the workpiece and improving the fixing effect. A slide rod 13 is provided on both the left and right sides of the upper surface of the cover plate 2. The other end of the slide rod 13 passes through the movable seat 10 and... The bottom surface of the top cover 12 is connected to the sliding rod 13, which can limit the sliding direction of the moving seat 10 and prevent the moving seat 10 from rotating synchronously with the screw 9. The driven gear 14 is rotatably connected to the middle position of the upper surface of the top cover 12. The top shaft of the screw 9 passes through the top cover 12 and is connected to the bottom surface of the driven gear 14. The driving gear 15 is rotatably connected to the front side of the upper surface of the top cover 12. The driving gear 15 meshes with the driven gear 14. By setting the driven gear 14, when the driven gear 14 rotates, it can drive the driving gear 15 to rotate, thereby driving the screw 9 to rotate.

[0024] Please see Figures 1-4In this embodiment, a cross-shaped locking block 16 is engaged on the top surface of the drive gear 15, and a handle 17 is connected to the top surface of the cross-shaped locking block 16. By setting the handle 17, when the handle 17 is needed, the cross-shaped locking block 16 can be engaged with the slot on the upper surface of the drive gear 15, and then the drive gear 15 can be rotated by the handle 17, thereby avoiding burns to the staff. Four circumferentially distributed mounting seats 18 are provided at the edge of the upper surface of the top cover 12, and a lifting ring 19 is provided on the top surface of the mounting seat 18. By setting the lifting ring 19, it is easy to lift the entire device, thereby placing it into and taking it out of the heat treatment furnace. Limiting frames 20 are provided at the edges of the upper surfaces of the cover plate 2 and the pressure plate 11. By setting the limiting frames 20, the edges of the upper surfaces of the cover plate 2 and the pressure plate 11 can be limited to prevent the workpiece from slipping.

[0025] During operation, the screw 9 rotates, driving the threaded movable seat 10 to move up and down. The movable seat 10 then drives the pressure plate 11 to move synchronously, thus pressing down the top of the workpiece and improving the fixing effect. The sliding rod 13 restricts the sliding direction of the movable seat 10, preventing it from rotating synchronously with the screw 9. The driven gear 14 rotates, driving the drive gear 15 to rotate, which in turn drives the screw 9 to rotate. The handle 17 engages the cross block 16 with the slot on the upper surface of the drive gear 15, allowing the drive gear 15 to rotate via the handle 17, thus preventing burns to workers. The lifting ring 19 facilitates the hoisting of the entire device, allowing it to be placed and removed from the heat treatment furnace. The limiting frame 20 limits the upper edge of the cover plate 2 and the pressure plate 11, preventing the workpiece from slipping.

[0026] Through the above steps, by setting the lever 7, the perforated plate 6 can be rotated inside the base plate 1 when the lever 7 is moved. Thus, the opening area of ​​the through hole 3 on the surface of the base plate 1 and the cover plate 2 can be adjusted through the perforated plate 6. When the perforated plate 6 rotates, the limiting rod 8 on the right side of the perforated plate 6 will slide inside the limiting groove 5 at the bottom of the slot 4. The limiting groove 5 can limit the sliding direction of the limiting rod 8, thereby improving the stability of the rotation of the perforated plate 6. This achieves the purpose of adjusting the area of ​​the through hole 3 to suit workpieces of different sizes. This solves the problem that the size of the hole in the bottom tray of the existing high-stability heat treatment lifting tool cannot be adaptively adjusted when in use, and it cannot be used for workpieces of various sizes. Smaller workpieces will fall out of the tray holes, while larger workpieces will have uneven heating at the bottom.
