Description

Technical Field

[0001] This utility model relates to the field of tool steering technology, and in particular to a tool 90-degree steering device. Background Technology

[0002] Milling cutters are mainly used for milling and cutting metal workpieces. They are often used to mill various planes, grooves, gear teeth, threads, splined shafts, and relatively complex profiles.

[0003] In actual machining processes, workpieces vary in shape and size, and sometimes it is necessary to machine the sides of the workpiece. Traditional milling cutter drive structures often cannot meet this requirement. This is mainly manifested in the fact that when machining the sides, it is often necessary to clamp and reposition the workpiece multiple times. This not only increases machining time but may also lead to a decrease in machining accuracy, resulting in a high defect rate and greatly affecting work efficiency. Utility Model Content

[0004] Based on this, the present invention provides a 90-degree tool turning device, which has a simple structure and is easy to use. The meshing of the first conical gear and the second conical gear realizes a 90-degree power turning between the output shaft and the input shaft, which greatly expands the application range of milling cutters. Especially when it is necessary to process the side of the workpiece, there is no need to clamp and reposition the workpiece multiple times, which significantly improves the processing efficiency and processing accuracy.

[0009] The aforementioned 90-degree tool turning device has a simple structure and is easy to use.

[0029] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0030] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0032] Please see Figures 1 to 8The tool 90-degree turning device according to one embodiment of the present invention includes an input shaft assembly 10 and an output shaft assembly 20 connected to the input shaft assembly 10; the axis of the output shaft assembly 20 is perpendicular to the axis of the input shaft assembly 10.

[0033] The input shaft assembly 10 includes a first housing 11, an input shaft 12 rotatably mounted inside the first housing 11, a first bevel gear 13 coaxially connected to the end of the input shaft 12, and an input shaft bearing 14 coaxially sleeved on the end of the input shaft 12.

[0034] Specifically, such as Figure 8 As shown, the end of the input shaft 12 passes through the first housing 11 and is coaxially connected to the first bevel gear 13 to ensure that the first bevel gear 13 rotates coaxially with the input shaft 12. The beginning of the input shaft 12 is conical, and the means of the input shaft 12 are designed by mimicking the shape of a tool holder, aiming to ensure that the input shaft 12 can be perfectly matched and securely clamped on the CNC machine tool. By mimicking the shape of a tool holder, this design not only improves the convenience of clamping but also enhances the stability and accuracy of clamping, thereby ensuring the efficient operation and precise control of the CNC machine tool during the machining process.

[0035] The output shaft assembly 20 includes a second housing 21 that is matched and connected to the first housing 11, an output shaft 22 rotatably mounted inside the second housing 21, a second bevel gear 23 coaxially connected to the middle of the output shaft 22, a tool holder 24 detachably mounted to one end of the output shaft 22, a limiting ring 25 fixedly mounted to the other end of the output shaft 22, a sealing cover 26 mounted to one end of the second housing 21, and a first output shaft bearing 27 and a second output shaft bearing 28 respectively sleeved at opposite ends of the output shaft 22. The tool holder 24 is used to support and mount the tool 30. The first output shaft bearing 27 is located on the side of the limiting ring 25 away from the sealing cover 26, so that the limiting ring 25 is located between the sealing cover 26 and the first output shaft bearing 27, effectively limiting the position of the limiting ring 25, preventing axial movement of the output shaft 22, avoiding the output shaft 22 from detaching from the second housing 21, and effectively ensuring the movement stability of the output shaft 22.

[0036] In this embodiment, the axis of the input shaft 12 is perpendicular to the axis of the output shaft 22. A through hole 210 is provided at the end of the second housing 21 facing the first housing 11, and the through hole 210 connects inward to the interior of the second housing 21; the through hole 210 corresponds to the second bevel gear 23. The first bevel gear 13 passes through the through hole 210 and meshes with the second bevel gear 23, allowing the power from the input shaft 12 to be transmitted to the output shaft 22. Since the axes of the first bevel gear 13 and the second bevel gear 23 are perpendicular to each other, the power direction of the output shaft 22 forms a 90-degree angle with the power direction of the input shaft 12.

[0037] In this embodiment, as Figures 5 to 7 As shown, the output shaft 22 has a through hole 221 along its axial direction in the middle. The tool holder 24 is inserted into one end of the through hole 221. A long bolt 29 is inserted into the other end of the through hole 221 and screwed onto the tool holder 24, thus connecting the tool holder 24 to the output shaft 22. Furthermore, positioning blocks 222 are connected to opposite sides of one end of the output shaft 22 corresponding to the through hole 221. Positioning notches 240 are provided on opposite sides of the end of the tool holder 24 that protrude beyond the output shaft 22. The positioning notches 240 are used to engage the positioning blocks 222 to ensure that the tool holder 24 and the output shaft 22 can rotate synchronously.

[0038] The aforementioned 90-degree tool turning device has a simple structure and is easy to use. The meshing of the first bevel gear 13 and the second bevel gear 23 realizes a 90-degree power turning between the output shaft 12 and the input shaft 22, which greatly expands the application range of the milling cutter. Especially when it is necessary to process the side of the workpiece, there is no need to clamp and reposition the workpiece multiple times, which significantly improves the processing efficiency and processing accuracy.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
