Description
Technical Field
[0001] This utility model relates to the field of heat treatment tooling technology, and in particular to a suspended heat treatment tooling for metal cylindrical parts. Background Technology
[0002] Heat treatment refers to a metal thermal processing technique that involves heating, holding, and cooling materials in their solid state to achieve the desired microstructure and properties. For example... Figure 1 The cylindrical metal parts shown are typically lifted during heat treatment by welding process rings to the lifting position. These welded process rings require machining removal during subsequent production, which is time-consuming, labor-intensive, and reduces production efficiency. Summary of the Invention
[0003] To address the problem of welding process rings at the lifting position during heat treatment of cylindrical metal parts, which requires subsequent machining for removal, this invention provides a suspended heat treatment tool for cylindrical metal parts. By using a support plate and support base, the tool eliminates the need to weld process rings at the lifting position, reducing processes and improving production efficiency.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A suspended heat treatment tooling fixture for metal cylindrical parts includes a support cylinder, a lifting assembly and a lifting beam. A rotating device is rotatably connected to the upper part of the support cylinder, and a support plate is provided on the top of the rotating device.
[0006] The lifting assembly is located on the upper part of the support plate and includes a connecting rod, a support base, and a connector. The support base is fixed to the bottom of the connecting rod and is snapped into the support plate. The connector is fixed to the top of the connecting rod.
[0007] The lifting beam is located on the upper part of the lifting assembly, and the connector is connected to the lifting beam. A lifting hook is provided on the upper part of the lifting beam.
[0008] Furthermore, the rotating device includes a connecting seat, a rotating seat, and multiple universal balls. The connecting seat is annular and fixed to the top of the support cylinder. The rotating seat has a T-shaped longitudinal section with a vertical through hole in the center. The lower part of the rotating seat fits into the connecting seat and is rotatably connected to it. After the rotating seat and the connecting seat are combined, they form an "I" shape and an annular cavity. The multiple universal balls are circumferentially arranged within the annular cavity. The support plate is located on top of the rotating seat. The rotating device facilitates the rotation of cylindrical metal parts mounted on it, improving work efficiency.
[0009] Furthermore, a circumferential groove is formed on the lower outer wall of the rotating seat, and a locking screw is connected to the side wall of the connecting seat. The end of the locking screw passes through the side wall of the connecting seat and is disposed in the groove. The locking screw facilitates the rotation of the rotating seat while restricting its vertical movement.
[0010] Furthermore, the support plate has a central hole in its center, the inner diameter of which is larger than the outer diameter of the support base. Multiple sector-shaped brackets are circumferentially arranged within the central hole of the support plate, each with a sector-shaped groove at its bottom. Multiple sector-shaped protrusions corresponding to the sector-shaped grooves of the sector-shaped brackets are fixed circumferentially on the outer wall of the support base. The distance between any two sector-shaped brackets is greater than the arc length of the sector-shaped protrusion. The matching arrangement of the sector-shaped grooves of the sector-shaped brackets and the sector-shaped protrusions of the support base facilitates the engagement of the sector-shaped protrusions of the support base with the sector-shaped grooves of the sector-shaped brackets of the support plate. This facilitates hoisting, locking the cylindrical metal parts between the support plate and the hoisting assembly, preventing the support plate from moving during hoisting and causing the cylindrical metal parts to slip, thus affecting the processing of the parts.
[0011] Furthermore, lifting lugs are fixed on both sides of the bottom of the lifting beam, and a connector is set between the two lifting lugs, with the connector rotatably connected to the two lifting lugs.
[0012] Furthermore, multiple reinforcing ribs are fixed between the two lugs.
[0013] Furthermore, the lifting beam includes two support beams and multiple support plates. The two support beams are spaced apart vertically, and multiple support plates are spaced apart along the length between the two support beams. A fixing plate is fixed in the middle between the two support beams, and a lifting rod is connected to the middle of the fixing plate. The lifting rod is positioned perpendicular to the two support beams. The lifting beam improves the stability of the lifting assembly.
[0014] Furthermore, the two support beams and multiple support plates form multiple grids, and counterweights are installed in the grids to further improve the stability of the lifting beam.
[0015] Furthermore, the lower part of the hook of the lifting hook is provided with a groove, the middle part of the lifting beam is fitted into the groove of the lifting hook, and the lifting rod is suspended at both ends of the groove of the lifting hook. This improves structural stability.
[0016] The beneficial effects of this utility model through the above technical solution are:
[0017] This invention utilizes a support plate and a lifting device to hoist and transport cylindrical metal parts into a heat treatment furnace, eliminating the need for welding process rings at the hoisting location, reducing procedures, and improving work efficiency. The invention also features a rotating device at the top of the support plate, facilitating the rotation of the cylindrical metal parts to allow the lifting assembly to pass through the support plate. Furthermore, the inclusion of a lifting beam and hook enhances stability during hoisting and movement, preventing swaying, safety hazards, and compromised performance. Attached Figure Description

Detailed Implementation
[0028] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings:
[0029] like Figures 2-9 As shown, a suspended heat treatment tool for metal cylindrical parts includes a support cylinder 2, a lifting assembly and a lifting beam 11. The bottom of the support cylinder 2 is provided with a base 1, which is fixedly connected to the supporting ground by bolts to improve the stability of the support cylinder 2.
[0030] A rotating device is fitted onto the upper part of the support cylinder 2. This rotating device includes a connecting seat 3, a rotating seat 5, and multiple universal balls 4. The connecting seat 3 is annular and fixed to the top of the support cylinder 2. The rotating seat 5 has a T-shaped longitudinal section with a vertical through hole in the center. The lower part of the rotating seat 5 fits into the connecting seat 3 and is rotatably connected to it. Specifically, a groove is circumferentially formed on the lower outer wall of the rotating seat 5. Multiple anti-reverse screws 18 are connected to the side wall of the connecting seat 3. In this embodiment, the anti-reverse screws 18 have threads on the upper part and a smooth cylindrical shape at the lower part. The ends of the anti-reverse screws 18 pass through the side wall of the connecting seat 3 and are positioned within the groove. This facilitates the rotation of the rotating seat 5 while restricting its vertical movement. After the upper part of the rotating seat 5 is combined with the connecting seat 3, it forms an "I" shape and an annular cavity. Multiple universal balls 4 are arranged circumferentially in the annular cavity. In this embodiment, the universal ball 4 is a heavy-duty hexagonal screw universal ball, and a single universal ball 4 is threadedly connected to the connecting seat 3.
[0031] The rotating device has a support plate 6 on its upper part. The upper part of the support plate 6 is cylindrical and stepped, and the lower part is an inverted frustum-shaped structure. The lower part of the support plate 6 fits into the central hole of the support base 7. The support plate 6 has a central hole in its middle, and the inner diameter of the central hole of the support plate 6 is larger than the outer diameter of the support base 7. Multiple sector-shaped brackets are arranged circumferentially inside the central hole of the support plate 6. Each sector-shaped bracket has a sector-shaped slot at its bottom. In this embodiment, there are three sector-shaped brackets.
[0032] The lifting assembly is located on the upper part of the support plate 6 and includes a connecting rod 8, a support base 7, and a connector 9. The support base 7 is fixed to the bottom of the connecting rod 8 and has a tubular structure. Multiple fan-shaped protrusions corresponding to the fan-shaped slots of the fan-shaped brackets are fixed circumferentially on the outer wall of the support base 7. In this embodiment, there are three fan-shaped protrusions. The distance between any two fan-shaped brackets is greater than the arc length of the fan-shaped protrusions, facilitating the passage of the fan-shaped protrusions of the support base 7 through the gaps between the fan-shaped brackets. The connector 9 is fixed to the top of the connecting rod 8.
[0033] The lifting beam 11 is located on the upper part of the lifting assembly. The lifting beam 11 includes two support beams 15 and multiple support plates 19. The two support beams 15 are spaced vertically apart, and multiple support plates 19 are spaced along the length between the two support beams 15. The two support beams 15 and the multiple support plates 19 form multiple grids, and counterweights 17 are installed within each grid. A fixing plate 16 is fixed at the center between the two support beams 15, and a lifting rod 12 is fixed between the fixing plates 16. The lifting rod 12 is positioned vertically to the two support beams 15, with both ends of the lifting rod 12 passing through the fixing plates 16 and suspended in mid-air. Both ends of the lifting rod 12 are equipped with retaining rings to prevent the lifting hooks 13 from sliding left and right during lifting. Lifting lugs 14 are fixed to both sides of the bottom of the lower beam, and multiple reinforcing ribs are fixed between the two lifting lugs 14 to improve the structural strength of the lifting lugs 14. The connector 9 is positioned between the two lugs 14. The connector 9 is connected to the two lugs 14 via a pin 10. A baffle is connected to the end of the pin 10 to prevent the connector 9 from slipping out of the lugs.
[0034] A lifting hook 13 is provided on the upper part of the lifting beam 11. The lower part of the hook 13 has a groove. The middle part of the lifting beam 11 fits into the groove of the lifting hook 13. The lifting rod 12 is suspended at both ends of the groove of the lifting hook 13. A lifting ring is provided on the upper part of the lifting hook 13 for easy suspension.
[0035] The base 1 is fixed to the supporting ground to prevent the support cylinder 2 from shifting or tipping over, affecting its use. Before use, the support seat 7 is separated from the support plate 6, that is, the lifting assembly and lifting beam 11 are separated from the support plate 6. When in use, the support plate 6 is placed on the rotating seat 5 of the rotating device, and the metal cylindrical part to be processed is fitted onto the support cylinder 2. Under the action of gravity, the inner end face of the metal cylindrical part is brought into contact with the top surface of the support plate 6. Then, the hook of the crane or overhead crane is suspended on the lifting ring of the lifting hook 13. As the lifting equipment moves the lifting hook 13 upward, the lifting hook 13 hooks the lifting rod 12 and moves upward. The lifting beam 11 and the lifting assembly move upward with the lifting rod 12. When the lifting assembly is suspended, the lifting equipment moves the lifting beam 11 and the lifting assembly to the top of the support cylinder 2. Then, the lifting equipment slowly lowers the lifting beam 11 and the lifting assembly downward to the hole of the metal cylindrical part to be processed, and then lowers again. At this point, the operator pushes the metal cylindrical part to rotate. Because the support plate 6 is in contact with the metal cylindrical part, the support plate 6 rotates with the metal cylindrical part. The lower part of the support plate 6 is fitted inside the rotating seat 5, which rotates with the support plate 6. When the fan-shaped protrusion of the support seat 7 of the lifting assembly passes through the hole in the metal cylindrical part and the fan-shaped slot of the support plate 6, the operator continues to push the metal cylindrical part to rotate, causing the fan-shaped protrusion of the support seat 7 to be positioned in the fan-shaped slot of the fan-shaped slot of the support plate 6. The lifting device moves the lifting assembly, and the support plate 6 detaches from the rotating seat 5. The lifting assembly moves the metal cylindrical part and the support plate 6 into the heat treatment furnace, while the rotating seat 5 and the support cylinder 2 remain in their original positions.

Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
