[0002] The machine tool spindle is a key component of the machine tool. During the use of the machine tool, the machine tool spindle often needs to be replaced or repaired and debugged, and generally requires the use of tooling to load and unload the machine tool spindle. Existing loading and unloading tooling for vertical machine tool spindles is mostly a fixed support structure. When replacing or installing and debugging the spindle, the tooling needs to be placed in the appropriate position, and the spindle needs to be pressed behind the tooling before loading and unloading or debugging operations can be carried out. Due to the fixed support, the spindle needs to be manually supported during loading and unloading, which is less safe. During installation, the spindle needs to be manually lifted to a fixed height, which places high demands on the installer and the installation process is time-consuming and labor-intensive.

[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0015] In the description of the embodiments of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," and the like, indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended solely for the purpose of facilitating the description of the embodiments of the present invention and simplifying the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific direction. Therefore, they should not be construed as limiting the embodiments of the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] like Figure 1 As shown, a loading and unloading tool for a machine tool spindle of the present invention comprises a base 1, a jacking device 2 and a support frame 3. Two jacking devices 2 are respectively installed on the base 1, and the support frame 3 is connected to the jacking device 2.

[0017] Combine Figure 1 and Figure 2As shown, the support frame 3 is a concave structure formed by bending a rigid plate. It includes a left transverse plate 31, a right transverse plate 32, a concave transverse plate 33, and a vertical plate 34. The left transverse plate 31 and the right transverse plate 32 are located on the left and right sides of the concave transverse plate 33, respectively. The two vertical plates 34 are located between the left transverse plate 31 and the concave transverse plate 33, and between the right transverse plate 32 and the concave transverse plate 33, respectively. A spindle support hole 35 is provided in the center of the concave transverse plate 33, and a protective pad 4 made of acrylic material is installed on the spindle support hole.

[0018] Combine Figure 1 and Figure 3 As shown, the lifting device 2 includes a base 21, a push rod 22, and a power control source 23. The base 21 is fixed to the base 1, and the push rod 22 is disposed within the base 21. The tops of the push rods 22 are respectively pressed against the left and right transverse plates 31 and 32 of the support frame 3. Under the action of the power control source 23, the push rods 22 can move up and down relative to the base 21, thereby driving the support frame 3 to move up and down. In this embodiment, the power control source 23 is driven by hydraulic or pneumatic drive, but can also be controlled by an electric or manual mechanical transmission structure.
