Description

Technical Field

[0001] The utility model belongs to the technical field of machining equipment, and particularly relates to a deep-hole milling groove device for a boring machine. Background Art

[0002] When milling a groove in a hole, a milling machine is usually used for processing. During processing, the tool rod needs to extend into the hole with the tool. Therefore, the deeper the hole, the longer the tool rod required. And the longer the tool rod, the greater the swing amplitude of the tool rod during processing, and the lower the machining accuracy. Therefore, the grooving of deep holes in workpieces with a large length-diameter ratio has always been a difficult problem in domestic machining, especially for large workpieces with a deep-hole length-diameter ratio of more than ten times. For example, for a deep-hole workpiece with a length of 5 meters and an inner hole diameter of 0.5 meters, the existing machine tools cannot enter the slender hole for processing. Currently, the known deep-hole machining machines can only machine deep holes with a diameter of more than 1 meter, but the machining depth is less than ten meters.

[0003] In domestic machining of large and ultra-deep internal keyways, only manual or semi-mechanical methods can be used, or the workpiece is processed in sections. The segmented processing can achieve sufficient groove line accuracy, but it is difficult to ensure the consistency of multiple groove lines. Manual and semi-mechanical processing are also difficult to ensure the accuracy of the keyway. This not only increases the labor intensity of the staff, reduces the processing efficiency of the factory, but also increases the processing cost and cannot meet the market demand.

[0035] It should be noted that the deep hole milling device needs to be used in conjunction with a boring machine. When in use, it is connected to the boring machine guide rod through the mounting frame, and the boring machine realizes feeding.

[0036] The beneficial effect of the deep hole milling groove device for a boring machine provided by the utility model is as follows: compared with the prior art, the deep hole milling groove device for a boring machine provided by the utility model is directly installed on the guide rod of the boring machine when in use, and is sent into the deep hole by the guide rod of the boring machine, and then, the milling cutter is driven to rotate by the self-contained driving assembly 40 to realize the grooving operation in the hole; since the deep hole milling groove device for a boring machine provided by the utility model is sent into the deep hole by the guide rod of the boring machine and has its own driving assembly 40, the length of the cutter bar 22 does not need to be increased with the increase of the hole depth, so it is easy to groove in the deep hole.

[0037] like Figure 1 and Figure 2 As shown, in a specific implementation of the deep hole milling device for a boring machine provided in an embodiment of the utility model, the mounting frame includes a connecting seat 11 and a shell 12, the connecting seat 11 is suitable for connecting to the guide rod of the boring machine, the driving assembly 40 is connected to the connecting seat 11; the shell 12 is connected to the connecting seat 11; the transmission assembly is connected to the shell 12, and the milling cutter extends out of the shell 12.

[0038] It should be noted that the mounting frame is divided into two parts, namely, a connecting base 11 and a housing 12 . On the one hand, it is convenient to connect with the boring machine guide rod. On the other hand, it is convenient to install the milling cutter and the transmission assembly inside the housing 12 and be protected by the housing 12 .

[0039] like Figure 2 and Figure 3 As shown, in a specific implementation of the deep hole milling device for a boring machine provided in an embodiment of the utility model, the milling cutter includes a cutter head 21 and a cutter rod 22, the cutter rod 22 is rotatably matched with the outer shell 12, the cutter head 21 is connected to the cutter rod 22, and the cutter head 21 extends from one side of the outer shell 12.

[0040] like Figure 3 As shown, in a specific implementation of the deep hole milling device for a boring machine provided in an embodiment of the utility model, it also includes two bearings 14, which are respectively sleeved on both ends of the tool rod 22 and connected to the outer shell 12 to reduce friction during rotation.
