Detailed Description

The following detailed description provides many different embodiments, or examples, for implementing the utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. In addition, repeated reference numerals, such as repeated numbers and/or letters, may be used in various embodiments. These repetition are for the purpose of simplicity and clarity in describing the utility model and do not in itself dictate a particular relationship between the various embodiments and/or configurations discussed.

The utility model is further described by the following drawings and detailed description:

as shown in fig. 1-3, a numerical control machine tool with a pneumatic tail top comprises a machine tool body 1, a working cavity 2, a main shaft 3, a chuck 4 and a tool rest 5 which are arranged in the working cavity 2, wherein a supporting frame 6 is detachably arranged in the working cavity 2, and a pneumatic tail top mechanism 7 is arranged on the supporting frame 6; through detachably mounting in working chamber 2 support frame 6, and pneumatic tail top mechanism 7 installs on support frame 6 to pneumatic tail top mechanism 7 is detachably mountable, need not to set up with the lathe is integrative, thereby compares traditional sword tower tail top lathe, and this technical scheme cost is with low costs, can install it in the lathe of high rotational speed moreover, and then can improve the cutting process of little axle class accessory greatly, and the suitability is wider, is fit for extensively popularizing and applying.

The numerical control machine tool in the present embodiment is a numerical control lathe.

Further, the supporting frame 6 is formed by splicing a plurality of steel plates through mortise and tenon structures and then welding, so that stability is greatly improved, and the pneumatic tail top mechanism 7 can work stably.

Further, the supporting frame 6 includes a frame 31, and a supporting plate 32 and a fixing plate 33 disposed at the upper and lower ends of the frame 31, the fixing plate 33 is detachably mounted on the side wall of the working cavity 2 through bolts and nuts, and the pneumatic tail top mechanism 7 is mounted on the supporting plate 32; therefore, the support frame 6 is convenient to install and detach, and when the pneumatic tail top mechanism 7 is not needed, the support frame 6 and the pneumatic tail top mechanism 7 can be detached together, so that the normal use of the machine tool is not affected.
