They cannot machine workpieces that exceed the machine tool travel. For example, when machining workpieces such as radiators and window frames, the machine tool travel needs to be greater than the workpiece length, which makes the mechanical structure of the machine tool very long, the body weight large, and production very inconvenient. Summary of the Utility Model

[0008] Preferably, the processing head is arranged above the workbench through a column. The column is fixed on the base, and a Z-axis guide rail slidably matched with the processing head is arranged on the column.

[0009] Preferably, a processing spindle for installing a tool is arranged inside the processing head.

[0010] Preferably, two fourth-axis rotary workbenches are provided, symmetrically distributed at the left and right ends of the workbench, and at least two symmetrically distributed retractable fixtures are arranged on each fourth-axis rotary workbench.

[0011] Preferably, the fourth-axis rotary table includes a mounting portion movably connected to the table, and a rotating portion that can rotate on the mounting portion under the action of a driving component. The annular space penetrates through the rotating portion and the mounting portion.

[0012] Preferably, the driving component includes a driving motor disposed on the mounting portion. The output end of the driving motor is connected to a first gear shaft, and a first gear on the first gear shaft meshes with a second gear on the rotating portion.

[0013] Preferably, the telescopic fixture is disposed on the rotating portion through a connecting member. The telescopic fixture includes a clamping plate and a driving member for driving the clamping plate to perform telescopic movement, and the clamping direction of the clamping plate is perpendicular to the axial direction of the workpiece.

[0021] The present utility model will be further clearly and completely described below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. The following description of at least one exemplary embodiment is actually only illustrative and in no way restricts the present utility model and its application or use. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0022] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0023] Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps set forth in these embodiments do not limit the scope of the present utility model. At the same time, it should be understood that for the sake of convenience of description, the sizes of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant fields may not be discussed in detail, but where appropriate, such technologies, methods, and devices should be regarded as part of the authorization specification. In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0024] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by orientation words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal", and "top, bottom" are generally based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Without contrary instructions, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of the present utility model; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0025] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper", etc. can be used here to describe the spatial positional relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figure for the device. For example, if the device in the attached figure is inverted, a device described as "above or over other devices or structures" will then be positioned "below or under other devices or structures". Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations are made for the spatial relative descriptions used here.

[0026] In addition, it should be noted that the use of terms such as "first", "second", etc. to define components is only for the convenience of differentiating the corresponding components. Without additional statements, the above terms have no special meanings, and thus should not be construed as limiting the protection scope of the present utility model.
