Description

Technical Field

[0001] This utility model relates to the field of workpiece processing technology, and in particular to a structure for supporting shaft-type workpieces. Background Technology

[0002] Clamping and machining shaft-type workpieces is a crucial step in mechanical manufacturing, and its quality and efficiency directly affect the performance of the final product. Currently, chucks are primarily used for clamping workpieces during machining. However, this method is time-consuming, requiring the workpiece to be placed in the chuck and then tightly secured. Furthermore, chucks can easily damage the workpiece surface, causing scratches. Therefore, there is a need to develop a structure that can quickly fix workpieces without clamping them to the workpiece surface. Utility Model Content

[0003] To address the aforementioned shortcomings, the purpose of this invention is to propose a structure for holding shaft-type workpieces, which can prevent damage to the workpiece surface and quickly fix the workpiece.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A structure for supporting a shaft-like workpiece includes a central center bar, a shifting center, an elastic element, a mounting sleeve, and a flange. One end of the central center bar is a supporting end, and the other end is a movable end. The movable end is installed inside the mounting sleeve and slides within it. The supporting end extends out of the mounting sleeve to support the workpiece. The elastic element is sleeved on the movable end, with one end supporting the movable end and the other end supporting the inside of the mounting sleeve. The shifting center is spaced within the supporting end, and a positioning post is provided around the supporting end on the outer side of the shifting center. The flange is sleeved on the outer side of the mounting sleeve.

[0006] Preferably, the outer end of the top holding end is conical.

[0007] Preferably, the positioning post is cone-shaped.

[0008] Preferably, the active end is T-shaped.

[0009] Preferably, the elastic element is a butterfly spring.

[0010] Preferably, the mounting sleeve has a through hole at its tail end, and a plug is installed at the tail end of the mounting sleeve, the plug being detachably installed at the tail end of the mounting sleeve.

[0011] Preferably, the end of the plug located inside the mounting sleeve is provided with a groove, and the groove is fitted onto one end of the movable end.

[0012] The technical solution provided by this utility model can include the following beneficial effects: one end of the workpiece is held against the center tip and the actuating tip, and the other end is held against the hydraulic tailstock of the machine tool. There is no need to clamp the outer surface of the workpiece, avoiding damage to the workpiece. Moreover, the installation of the workpiece is fast when it is processed on the machine tool. First, one end of the workpiece is held against the center tip and the actuating tip, and then the hydraulic tailstock of the machine tool is pushed to hold the other end of the workpiece. One end of the elastic element is held against the movable end, and the other end of the elastic element is held against the inside of the mounting sleeve. When the center tip and the actuating tip hold the end face of the workpiece, the center tip can be pushed towards the end face of the workpiece by the elastic element, making the workpiece more stable. When used with the hydraulic tailstock, the workpiece can be clamped and processed in one go without turning it over for processing. Attached Figure Description

[0019] The following is combined with Figure 1 This describes the structure of a top-holding shaft-type workpiece according to an embodiment of the present utility model.

[0020] A structure for supporting shaft-like workpieces includes a central center bar 1, a pivoting center 2, an elastic element 3, a mounting sleeve 4, and a flange 5. One end of the central center bar 1 is a supporting end, and the other end is a movable end. The movable end is installed inside the mounting sleeve 4 and slides inside the mounting sleeve 4, while the supporting end protrudes outside the mounting sleeve 4 to support the workpiece. The elastic element 3 is sleeved on the movable end, with one end of the elastic element 3 supporting the movable end and the other end supporting the inside of the mounting sleeve 4. The pivoting center 2 is spaced and sleeved on the supporting end, and a positioning post 21 is provided around the supporting end on the outer side of the pivoting center 2. The flange 5 is sleeved on the outer side of the mounting sleeve 4.

[0021] A structure for supporting shaft-like workpieces is disclosed. One end of the workpiece is supported by a central center bar 1 and a moving center 2, while the other end is supported by a hydraulic tailstock of a machine tool. This eliminates the need to clamp the outer surface of the workpiece, avoiding damage. Furthermore, the workpiece is quickly mounted for machining on the machine tool; first, one end of the workpiece is supported by the central center bar 1 and the moving center 2, and then the hydraulic tailstock of the machine tool is used to push and support the other end of the workpiece.

[0022] One end of the elastic element 3 rests against the movable end, and the other end rests against the inside of the mounting sleeve 4. This allows the center center bar 1 to be pushed towards the end face of the workpiece by the elastic element 3 when the center center bar 1 and the actuating center 2 are pressing against the workpiece end face, making the workpiece more stable. When used in conjunction with a hydraulic tailstock, the workpiece can be machined into a shaft in one clamping operation without having to turn it around for further processing.

[0023] Specifically, the outer end of the supporting end is designed to be conical. This helps to hold it within the positioning groove on the end face of the workpiece.

[0024] Specifically, the positioning post 21 is designed in a conical shape. This helps to hold it firmly within the positioning groove on the end face of the workpiece.

[0025] Specifically, the movable end is T-shaped. This facilitates the movement of the movable end by the elastic element 3.

[0026] Specifically, the elastic element 3 is a disc spring. This makes it easy to fit onto the movable end, and the disc spring has better elasticity.

[0027] Specifically, the mounting sleeve 4 has a through hole at its tail end, and a plug 41 is installed at the tail end of the mounting sleeve 4. The plug 41 is detachably installed at the tail end of the mounting sleeve 4. This facilitates the installation of the elastic element 3. After the plug 41 is installed, one end of the elastic element 3 can be held against the end face of the plug 41.

[0028] To further explain, the end of the blocking block 41 located inside the mounting sleeve 4 is provided with a groove 42, which is fitted onto one end of the movable end. When the movable end moves toward the blocking block 41, the movable end can be inserted into the groove 42, making it less likely for the movable end to wobble during movement.

[0029] Other configurations and operations of the structure for supporting shaft-type workpieces according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.

[0030] In this specification, the terms "embodiment," "example," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0031] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
