[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-2 As shown, the utility model provides a combined switching structure of the fourth rotating axis and the fifth rotating axis of a machine tool, which is mainly used for machine applications, and can flexibly switch between the fourth rotating axis and the fifth rotating axis to form a variety of different usage structures. Its specific structure mainly includes a base plate 1, and the surface of the base plate 1 is provided with a supporting tailstock 2 connected to the front end and a four-axis body 3 connected to the rear end, the output end of the four-axis body 3 is aligned forward with the supporting tailstock 2, and the output end of the four-axis body 3 is also connected to a detachable five-axis body 4, and the output end of the five-axis body 4 faces upward. On the base plate 1, the four-axis body 3 or the five-axis body 4 can be switched to use according to whether the five-axis body 4 is assembled. When the five-axis body 4 is not assembled, the four-axis body 3 can be used to rotate, and when the five-axis body 4 is assembled, only the five-axis body 4 can be used to rotate. Both the four-axis body 3 and the five-axis body 4 can be fixed by the supporting tailstock 2 at the front end.

[0026] When the four-axis body 3 is connected to the five-axis body 4, a supporting and fixing block 5 is connected and fixed between the five-axis body 4 and the supporting tailstock 2. In this case, only the five-axis body 4 can be used for processing, and the parts to be processed are fixed at the upward output end of the five-axis body 4, and then the parts are rotated in the horizontal direction synchronously when the output end of the five-axis body 4 rotates. At this time, the front end of the five-axis body 4 can also be connected to the supporting and fixing block 5 to strengthen the fixation between the five-axis body 4 and the supporting tailstock 2.

[0027] One end of the support fixing block 5 is provided with a first fixing portion 8 fixedly connected to the front end of the five-axis body 4, and the other end is provided with a second fixing portion 9 fixedly connected to the support tailstock 2. After the first fixing portion 8 and the second fixing portion 9 of the support fixing block 5 are connected, they can be locked and fixed by screws.

[0028] When the four-axis body 3 and the five-axis body 4 are not connected, a synchronously rotating rotating shaft 6 is connected between the output end of the four-axis body 3 and the supporting tail stock 2, and a coaxially conductive slot 7 is provided between the supporting tail stock 2 and the output end of the four-axis body 3. In this case, only the four-axis body 3 can be used for processing, and the part to be processed is fixed at the forward output end of the four-axis body 3, and then the part is synchronously longitudinally rotated and processed when the output end of the four-axis body 3 rotates. At this time, the front end of the four-axis body 3 can also be connected to the rotating shaft 6 to strengthen the fixation between the supporting tail stock 2, and at the same time, the supporting tail stock 2 is additionally provided with a slot 7 that is linearly conductive with the output end of the four-axis body 3. The part to be processed is inserted from one end of the supporting tail stock 2 to the output end of the four-axis body 3 and fixed, thereby improving the firmness of the part in the horizontal direction, and the slot 7 can also be coaxially conductive through the inside of the rotating shaft 6.

[0029] One end of the rotating shaft 6 is provided with a first connecting portion 10 connected to the output end of the four-axis body 3, and the other end is provided with a second connecting portion 11 that is inserted into the tailstock 2 to support rotation. After the first connecting portion 10 and the second connecting portion 11 of the rotating shaft 6 are connected, they can also be fixed by screws.

[0030] It is necessary to add that, if Figure 3-4 As shown, locking parts 12 for locking with the base plate 1 are provided on both sides of the four-axis body 3, and the locking parts 12 are provided with holes for locking with the base plate 1 by screws. At the same time, the support tailstock 2 is a detachable structure relative to the base plate 1. Therefore, the four-axis body 3 and the five-axis body 4 can also operate independently without the support tailstock 2 for strengthening and fixing.

[0031] Compared with traditional technologies, when using the machine tool, the user can freely and quickly switch between the four-axis body 3 and the five-axis body 4 according to the needs of producing parts, and connect and support the tailstock 2 as needed, which effectively expands the scope of machine tool processing, improves work results and reduces costs.

[0032] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention, and any figure mark in the claims should not be regarded as limiting the claims involved.
