Description

Technical Field

[0001] This utility model relates to a tooling lifting device for a fixed-axis salt bath. Background Technology

[0002] When performing salt bath nitriding on fixed shafts, specialized tooling and lifting equipment are typically used. Currently, the height of the tooling and lifting equipment used for salt bath treatment of fixed shafts remains fixed. When performing salt bath treatment on fixed shafts of different lengths, it is necessary to change to the corresponding model of tooling and lifting equipment, which increases costs. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned deficiencies in the existing technology and to provide a fixed-axis salt bath tooling hoist with a reasonable structural design.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: the fixed-axis salt bath tooling lifting device has the following structural features: it includes a fixed frame, a lifting frame, and an adjusting structure. The lifting frame and the adjusting structure are both set on the fixed frame, and the adjusting structure is connected to the lifting frame to control the lifting frame to rise and fall on the fixed frame. The fixed frame includes a fixed plate and a fixed sleeve. The fixed sleeve is fixedly set on the fixed plate. The lifting frame includes a lifting plate and a lifting sleeve. The lifting sleeve is fixedly set on the lifting plate and is located inside the fixed sleeve. The adjusting structure passes through the lifting sleeve, and one end of the adjusting structure is rotatably set on the fixed plate.

[0005] Furthermore, the adjustment structure includes a lifting ring, an adjusting rod, and a limiting block. The lifting ring and the limiting block are respectively fixedly installed at both ends of the adjusting rod. The adjusting rod passes through the lifting sleeve and is threadedly connected to the lifting sleeve.

[0006] Furthermore, a limiting seat is provided on the fixed disk, and the limiting block is rotatably mounted on the limiting seat.

[0007] Furthermore, the fixed sleeve is provided with a guide groove, and the lifting sleeve is provided with a guide block, the guide block being located within the guide groove.

[0008] Furthermore, the fixed plate is provided with a limit groove, and the lifting plate is provided with a limit hole, with the limit hole corresponding to the limit groove.

[0009] Compared with the prior art, the present invention has the following advantages: When performing salt bath treatment on fixed shafts of different lengths, the height of the lifting frame relative to the fixed frame can be adjusted, thereby enabling the same tooling to perform salt bath treatment on various types of fixed shafts, thus reducing costs.

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0014] Example.

[0015] See Figures 1 to 2 As shown in the accompanying drawings, the structures, proportions, sizes, etc., depicted in this specification are merely for illustrative purposes to aid those skilled in the art and to provide a clear understanding. They are not intended to limit the scope of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the use of terms such as "upper," "lower," "left," "right," "middle," and "one" in this specification is solely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0016] The fixed-axis salt bath tooling lifting device in this embodiment includes a fixed frame 1, a lifting frame 2, and an adjusting structure 3. The lifting frame 2 and the adjusting structure 3 are both mounted on the fixed frame 1, and the adjusting structure 3 is connected to the lifting frame 2 to control the lifting frame 2 to move up and down on the fixed frame 1.

[0017] In this embodiment, the fixed frame 1 includes a fixed plate 11 and a fixed sleeve 12. The fixed sleeve 12 is fixedly mounted on the fixed plate 11. The lifting frame 2 includes a lifting plate 21 and a lifting sleeve 22. The lifting sleeve 22 is fixedly mounted on the lifting plate 21 and is located inside the fixed sleeve 12. The adjusting structure 3 passes through the lifting sleeve 22, and one end of the adjusting structure 3 is rotatably mounted on the fixed plate 11.

[0018] The adjustment structure 3 in this embodiment includes a lifting ring 31, an adjusting rod 32, and a limiting block 33. The lifting ring 31 and the limiting block 33 are respectively fixedly installed at both ends of the adjusting rod 32. The adjusting rod 32 passes through the lifting sleeve 22 and is threadedly connected to the lifting sleeve 22. A limiting seat 15 is provided on the fixed plate 11, and the limiting block 33 is rotatably installed on the limiting seat 15.

[0019] In this embodiment, the fixed sleeve 12 is provided with a guide groove 13, the lifting sleeve 22 is provided with a guide block 23, the guide block 23 is located in the guide groove 13, the fixed plate 11 is provided with a limit groove 14, and the lifting plate 21 is provided with a limit hole 24, the limit hole 24 and the limit groove 14 are provided correspondingly.

[0020] Specifically, when using the fixed shaft salt bath tooling, the fixed shaft can be passed through the limiting hole 24, and one end of the limiting hole 24 can be inserted into the limiting hole 24. The lifting ring 31 is then lifted by the lifting equipment to perform salt bath treatment on the fixed shaft. The height position of the lifting frame 2 relative to the fixed frame 1 can be adjusted, so that it can be used for salt bath treatment of fixed shafts of different lengths. When adjusting the height of the lifting frame 2, the adjusting rod 32 can be rotated. Since the adjusting rod 32 is threadedly connected to the lifting sleeve 22, the lifting sleeve 22 can move up and down relative to the fixed sleeve 12, so that the height position of the lifting plate 21 relative to the fixed plate 11 can be adjusted, thus facilitating the salt bath treatment of fixed shafts of different lengths.

[0021] Furthermore, it should be noted that the specific embodiments described in this specification may differ in the shape and name of their components. The above description is merely illustrative of the structure of this utility model.
