[0022] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments in accordance with the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and / or "comprising," when used in this specification, specify the presence of stated features, steps, operations, elements, components, and / or groups thereof, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or groups thereof.

[0023] The relative arrangement of parts and steps, numerical expressions, and numerical values set forth in the examples are not intended to limit the scope of the application, unless otherwise specifically stated. It should be apparent that the dimensions of the various parts shown in the drawings are not to scale and are only meant to illustrate the general principles of the application. Techniques, methods, and apparatus known to those of ordinary skill are not discussed in detail because they would be apparent in light of the description herein. In all examples shown and discussed herein, any specific values are to be interpreted as illustrative only and not limiting. Thus, other examples of example embodiments can have different values. It should be noted that like reference numerals and letters in the various figures indicate like elements, and therefore, further discussion of the same will not be repeated in the subsequent figures.

[0024] In the description of the present application, it should be understood that the orientation words such as "front, back, up, down, left, right", "transverse, vertical, perpendicular, horizontal" and "top, bottom" and the like indicated orientation or position relationship are generally based on the orientation or position relationship shown in the drawings, only for the convenience of describing the present application and simplifying the description, without the opposite indication, these orientation words do not indicate and imply that the indicated device or element must have a specific orientation or be constructed and operated in a specific orientation, therefore, it cannot be understood as a limitation on the scope of protection of the present application: the orientation words "inner, outer" refer to the inner and outer relative to the contour of each component.

[0025] For ease of description, spatial relative terms such as "above," "over," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation besides the orientation of the device as described in the figures. For example, if the device in the figures is inverted, a device described as "above" or "above" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0026] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0027] like Figures 1-6 As shown in the figure, this invention discloses a portable thread milling machine for ship rudder stock, including a workpiece limiting device, a rolling device, and a milling machine module. The workpiece limiting device is used to clamp the root of the rudder stock to be milled through an adjustable clamping part. The rolling device contacts the rudder stock to be milled to complete the rotation of the rudder stock. The milling machine module includes a milling machine 9 for milling the threads of the rudder stock. The milling machine used in this embodiment is a pneumatic thread milling machine, which can use existing equipment.

[0028] Furthermore, the workpiece limiting device includes a first horizontal bar 1, a second horizontal bar 2, a first vertical bar 3, and a second vertical bar 4. The first horizontal bar, the second horizontal bar, the first vertical bar, and the second vertical bar form a frame structure. The root of the rudder rod to be milled is located within the frame structure, specifically at the bottom of the frame structure. In the illustration, the first horizontal bar, the second horizontal bar, the first vertical bar, and the second vertical bar form a regular tetrahedral structure. In practical applications, the second vertical bar will deviate from the other three sides based on the workpiece specifications, causing the overall frame to form a trapezoidal structure. Generally, it is an inverted trapezoidal structure with the upper base length greater than the lower base length.

[0029] Furthermore, the first horizontal bar is connected to the first vertical bar and the second vertical bar by a hinge and a hinge fixing device is provided. After adjusting the angle of the first vertical bar and the second vertical bar relative to the first horizontal bar based on the specifications of the workpiece, the positional relationship between the first horizontal bar and the first vertical bar and the second vertical bar is limited by the hinge fixing device.

[0030] Further, the second cross bar is provided with a positioning sliding module and a sliding module fixing device between the first vertical bar and the second vertical bar. After determining the positional relationship between the first cross bar and the first vertical bar and the second vertical bar, the distance between the second cross bar and the first cross bar is adjusted by the positioning sliding module, and then the positional relationship between the second cross bar and the first vertical bar and the second vertical bar is limited by the sliding module fixing device. Specifically, the positioning sliding module specifically includes a connecting rod and a sliding rod, the connecting rod is connected with the sliding rod, and the sliding rod is sleeved on the vertical bar. Specifically, the sliding rod of the first positioning sliding module 10 is installed on the first vertical bar, the sliding rod of the second positioning sliding module 11 is installed on the second vertical bar, and the connecting rods of the first positioning sliding module and the second positioning sliding module are installed at two ends of the second cross bar.

[0031] Further, the root milling machine is installed on the second cross bar, and the root milling machine is connected with a position adjusting mechanism and an air source pipe. The air source pipe is used to provide power for the cutter head of the root milling machine. The position adjusting mechanism includes a rotating bolt. The root milling machine moves up and down by rotating the rotating bolt. As a preferred embodiment, the root milling machine is installed on the vertical bar with a small action range. In this embodiment, the second vertical bar is mainly adjusted in angle, so the root milling machine is installed on the first vertical bar.

[0032] Further, the first vertical bar is connected with a first rolling pulley module 1 and a second rolling pulley module 7, and the second vertical bar is provided with a third rolling pulley module 6 and a fourth rolling pulley module 8. The two rolling pulleys in the same direction can adjust the distance between them. Specifically, the pulleys arranged at the bottom can be fixed in position by the device. The two fixed pulleys are located at the same horizontal position, i.e. they are symmetrically arranged around the central axis of the device. The pulleys arranged above slide up and down along the vertical bar as a slide. In the initial position, the two movable pulleys are located at the same horizontal position, i.e. they are symmetrically arranged around the central axis of the device. In this embodiment, the rotation of the rolling pulley module is manually rotated. The pulleys can contact the workpiece by adjusting, and the root milling operation of the workpiece is completed. In other alternative embodiments, an electric or other automatic rotating device can also be provided to complete the rolling of the pulleys, and then drive the workpiece to rotate around the preset angle.

[0033] The root milling method comprises the following steps:

[0034] S1, placing the rudder rod to be milled in the workpiece limiting device;

[0035] S2, adjusting the workpiece limiting device until the rudder rod to be milled can contact each rolling device, and at the same time, the root milling machine is placed above the rudder rod to be milled, and specifically, the bottom cutter head of the root milling machine is in contact with the root of the workpiece;

[0036] S3, the root milling machine works, through the adjustment of the motion state of the rolling device, the completion of the rudder rod milling operation.

[0037] In actual use, generally only need to end thread of a section of milling, rolling device can complete the workpiece rotation of a certain angle.

[0038] Finally, it should be noted that: the above examples are used to illustrate the technical solutions of the present application, rather than limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
