Description

Technical Field

[0001] This utility model relates to the technical field of vacuum furnace auxiliary devices, specifically to a novel crucible loading and unloading mechanism. Background Technology

[0002] With the continuous maturation of vacuum metallurgy and vacuum heat treatment processes, corresponding ultra-high vacuum furnaces are also developing towards greater economic efficiency, large-scale production, and larger-scale applications. In some production processes that require frequent crucible handling, manual crucible handling is inefficient and cannot meet the demands of large-scale production. Traditional mechanical crucible handling mechanisms have the following problems: 1. Multiple sets of machinery are required to handle the loading and unloading of materials from the crucible, and the turnaround time for each operation is long.

[0003] 2. When the crucible is lifted or placed over a long period of time using a flexible connection with a wire rope hook, it is easy for the crucible to sway and bump. Utility Model Content

[0004] The purpose of this invention is to provide a novel crucible loading and unloading mechanism that is structurally sound and reliable in use, which solves the above-mentioned problems, greatly improves production efficiency, meets the needs of automated equipment integration in modern production, and facilitates the automated control of the entire production process.

[0005] The technical solution of this utility model is: A novel crucible loading and unloading mechanism includes a support column for mounting on the side of a vacuum furnace. The key technical features are: the lower end of the support column is fixedly connected to a hollow rotating platform, and the upper end is fixed with a horizontal cantilever. The free end of the horizontal cantilever is fixed with an XY-axis hollow moving platform. A longitudinal multi-stage telescopic electric cylinder is fixed above the XY-axis hollow moving platform. The lower end of the cylinder rod of the longitudinal multi-stage telescopic electric cylinder passes through the hollow hole of the XY-axis hollow moving platform and is fixedly connected to the upper surface of a connecting frame. A vacuum suction cup is provided on the lower surface of the connecting frame.

[0006] In the novel crucible loading and unloading mechanism described above, a positioning sleeve is fixed at the center of the lower end face of the connecting frame, and a buffer spring is fitted on the vacuum suction column of the vacuum suction cup, with the upper end of the vacuum suction column passing through the positioning sleeve and connected to a limiting nut.

[0007] In the aforementioned novel crucible loading and unloading mechanism, the outer circumferential surface of the positioning sleeve is provided with an external thread, and the upper adjusting nut and the lower adjusting nut are connected by the external thread. The lower end face of the connecting frame is provided with a through hole corresponding to the positioning sleeve. The upper adjusting nut and the lower adjusting nut are respectively located above and below the lower end face of the connecting frame and clamp the lower end face of the connecting frame.

[0008] In the aforementioned novel crucible loading and unloading mechanism, a handle is provided on the side of the horizontal cantilever.

[0009] The beneficial effects of this utility model are: 1. The hollow rotating platform enables 360-degree rotation of the supporting column, horizontal cantilever, XY-axis hollow moving platform, longitudinal multi-stage telescopic electric cylinder, connecting frame, and vacuum suction cup. The XY-axis hollow moving platform also allows for two-way micro-adjustment of the longitudinal multi-stage telescopic electric cylinder, connecting frame, and vacuum suction cup, thereby adjusting the horizontal position for material handling to ensure the vacuum suction cup is centered on the vacuum furnace. The longitudinal multi-stage telescopic electric cylinder allows for height adjustment of the handling height, significantly reducing the space occupied by the equipment. These rotating, translating, and lifting structures enable rapid sample handling of the crucible at different positions, improving automation and significantly increasing production efficiency in modern industrial production.

[0010] 2. This mechanism uses a vacuum suction cup to pick up and place crucibles, greatly preventing damage to the crucible surface and protecting it. It is suitable for crucibles of different diameters. Simultaneously, a buffer spring is fitted onto the vacuum suction column of the vacuum suction cup to effectively protect the crucible from impact damage during retrieval and descent.

Detailed Implementation

[0013] The present invention will be described in detail with reference to the accompanying drawings.

[0014] like Figures 1-4As shown, this novel crucible loading and unloading mechanism includes a support column 5 positioned on the side of a vacuum furnace. The lower end of the support column 5 is connected and fixed to a hollow rotating platform 6, and the upper end is fixed to a horizontal cantilever 3. An XY-axis hollow moving platform 2 is fixed to the free end of the horizontal cantilever 3. A longitudinal multi-stage telescopic electric cylinder 1 is fixed above the XY-axis hollow moving platform 2. The lower end of the cylinder rod of the longitudinal multi-stage telescopic electric cylinder 1 passes through the hollow hole of the XY-axis hollow moving platform 2 and is then connected and fixed to the upper surface of a connecting frame 9. A handle 4 is provided on the side of the horizontal cantilever 3.

[0015] The lower end face of the connecting frame 9 is provided with a vacuum suction cup 8. In this embodiment, a positioning sleeve 11 is fixed at the center of the lower end face of the connecting frame 9. A buffer spring 13 is fitted on the vacuum suction column of the vacuum suction cup 8, and the upper end of the vacuum suction column passes through the positioning sleeve 11 and is connected to a limiting nut 10. The outer circumferential surface of the positioning sleeve 11 is provided with external threads, and the upper adjusting nut 12 and the lower adjusting nut 14 are connected by the external threads. The lower end face of the connecting frame 9 is provided with a through hole corresponding to the positioning sleeve 11. The upper adjusting nut 12 and the lower adjusting nut 14 are located above and below the lower end face of the connecting frame 9, respectively, and clamp the lower end face of the connecting frame 9. During the material handling process, the vacuum suction column of the vacuum suction cup 8 and the positioning sleeve 11 can generate relative movement.

[0016] Working principle: 1. When the crucible 7 is taken into the vacuum furnace, the hollow rotating platform 6 provides rotational power to drive the support column 5, horizontal cantilever 3, XY axis hollow moving platform 2, longitudinal multi-stage telescopic electric cylinder 1, connecting frame 9 and vacuum suction cup 8 to rotate around the support column 5 so that the vacuum suction cup 8 is positioned above the vacuum furnace.

[0017] 2. Manually adjust the hollow moving platform 2 of the XY axes to align the vacuum suction cup 8 with the center of the furnace body.

[0018] 3. Open the furnace cover. The cylinder rod of the longitudinal multi-stage telescopic electric cylinder 1 drives the connecting frame 9 and the vacuum suction cup 8 to move downward. After the crucible 7 is sucked up, the cylinder rod of the longitudinal multi-stage telescopic electric cylinder 1 rises, driving the connecting frame 9, the vacuum suction cup 8 and the crucible 7 out of the vacuum furnace.

[0019] 4. Start the hollow rotating platform 6, which drives the horizontal cantilever 3, the XY axis hollow moving platform 2, the longitudinal multi-stage telescopic electric cylinder 1, the connecting frame 9, the vacuum suction cup 8 and the crucible 7 to rotate to the target position. Then, the longitudinal multi-stage telescopic electric cylinder 1 drives the connecting frame 9, the vacuum suction cup 8 and the crucible 7 to move downwards, placing the crucible 7 at the target position, and the material in the crucible 7 can be taken out.

[0020] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model.
