[0034] The following introduces multiple preferred embodiments of the present utility model with reference to the accompanying drawings of the specification to make its technical content clearer and easier to understand. The present utility model can be embodied in many different forms of embodiments, and the protection scope of the present utility model is not limited to the embodiments mentioned in the text.

[0035] In the drawings, components with the same structure are denoted by the same numerical reference signs, and components with similar structures or functions everywhere are denoted by similar numerical reference signs. The size and thickness of each component shown in the drawings are arbitrarily shown, and the present utility model does not limit the size and thickness of each component. In order to make the illustration clearer, the thickness of some parts in the drawings is appropriately exaggerated.

[0036] The present utility model relates to the external cylindrical surface boring machining of non-metal and metal parts, and is mainly applied to equipment such as boring machines, drilling machines, ordinary milling machines, CNC milling machines, and CNC machining centers.

[0037] Based on the existing internal hole boring tool, the present utility model designs a conversion module, which can adapt to different cylinder diameters and machining interference conditions, and realizes the boring machining of the cylindrical side wall with high shape accuracy, high position accuracy, low procurement cost, and high flexibility.

[0038] As Figures 1-5 shown, the present utility model provides a conversion module for converting an internal hole boring tool into an external hole boring tool, including a clamping rod 1 and a conversion block 2. The clamping rod 1 is configured to be able to cooperate and fix with the first clamping hole of the boring tool 3. The conversion block 2 includes a clamping mechanism, and the clamping mechanism is configured to be able to cooperate and fix with the boring tool rod 4. The central axis of the clamping mechanism is parallel to the central axis of the clamping rod 1, and the central axis of the clamping mechanism is disposed outside the central axis of the clamping rod 1.

[0039] For cylinders with different diameters to be bored, the structure of the conversion module is different: for cylinders with a diameter ≤ 6 mm, due to the compact structure, the clamping rod 1 and the conversion block 2 are designed as an integral structure (see Figure 1 , 2);For a cylinder with a diameter > 6 mm, the clamping rod 1 and the conversion block 2 are designed as a split structure (see Figure 3 、 4 ). The clamping rod 1 and the conversion block 2 are detachably connected. The conversion block 2 is provided with a mounting counterbore. One end of the clamping rod 1 is inserted through the mounting counterbore. The conversion module further includes a mounting bolt 6, and the mounting bolt 6 is inserted through the other end of the mounting counterbore and fixed in a threaded hole provided in the clamping rod 1.

[0040] As Figures 1-5 shown, the clamping mechanism may include a second clamping hole 5, and the second clamping hole 5 is provided on the front end face of the conversion block 2.

[0041] A fastening screw hole 7 is provided on the side surface of the conversion block 2, and the fastening screw hole 7 is configured to be able to screw in a fastening screw to fix the boring bar 4 on the conversion block 2.

[0042] When the boring bar 4 is fixed on the conversion block 2, the cutting edge of the boring blade installed at the front end of the boring bar 4 faces the central axis of the clamping rod 1.

[0043] The projection of the boring blade on a plane perpendicular to the central axis of the clamping rod 1 is located on the line connecting the axis of the clamping rod 1 and the axis of the second clamping hole 5.

[0044] The clamping rod 1 and the second clamping hole 5 have the same size.

[0045] The installation method of this conversion module:

[0046] The clamping rod 1 of the conversion module is inserted into the first clamping hole of the boring tool 3 of the processing equipment for mating and fixing (the diameter or specification style of the clamping rod 1 can be flexibly adjusted according to the clamping structure of the boring tool 3). The conversion block 2 has a clamping structure for mating with the boring bar 4. The boring bar 4 extends into the conversion block 2, and the boring bar 4 is fixed through the fastening screw hole 7 on its side surface (the clamping structure can be flexibly adjusted according to the specification and shape of the boring bar 4).

[0047] The usage method of this conversion module:

[0048] First, the boring bar 4 is loaded and fixed in the conversion module, and then the conversion module is fixed on the boring tool 3. At this time, the boring bar 4 rotates 180° compared with when it is directly loaded into the boring tool 3, and is converted from the internal boring state to the external boring cylinder state (see Figure 5 ). By adjusting the adjustment mechanism on the boring tool 3, the diameter of the bored cylinder 8 can be accurately controlled to achieve the processing effect of high cylindricity and high position accuracy.

[0049] The preferred specific embodiments of the present utility model have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present utility model without creative work. Therefore, all technical solutions that can be obtained by those skilled in the art in this technical field through logical analysis, reasoning, or limited experiments based on the concept of the present utility model on the basis of the prior art should fall within the protection scope determined by the claims.
