In addition, term " first ", " second " only for describing object, and can not be interpreted as instruction or hint relative importance or imply the quantity indicating indicated technical characteristic.Thus, be limited with " first ", the feature of " second " can express or impliedly comprise one or more these features.In description of the present utility model, the implication of " multiple " is two or more, unless otherwise expressly limited specifically.
In the utility model, unless otherwise clearly defined and limited, the term such as term " installation ", " being connected ", " connection ", " fixing " should be interpreted broadly, and such as, can be fixedly connected with, also can be removably connect, or connect integratedly; Can be mechanical connection, also can be electrical connection; Can be directly be connected, also indirectly can be connected by intermediary, can be the connection of two element internals.For the ordinary skill in the art, the concrete meaning of above-mentioned term in the utility model can be understood as the case may be.
Shown in Fig. 2, the utility model embodiment provides a kind of step deep hole machining and bores, and for processing the deep hole with step surface, this step deep hole machining drilling tool body comprises drilling rod 10 and drill bit.
Concrete, one end of drilling rod 10 is free end, and the other end is link.In embody rule, in being connected with the main shaft on machining tool, being bored by main shaft drives processing and rotating to carry out deep hole machining.
Drill bit comprises macropore processing sections 20 and aperture processing sections 203, one end of macropore processing sections 20 is fixedly connected with the link of drilling rod 10, the other end of macropore processing sections 20 is fixedly connected with one end of aperture processing sections 203 and forms a cutting face 201 at link position, cutting face 201 is formed with the first blade 202 for processing macropore, the other end of aperture processing sections 203 is provided with the second blade 211 for machining small.
It should be noted that, the diameter of macropore processing sections 20 is slightly larger than the diameter of drilling rod 10, and the diameter of aperture processing sections 203 is less than the diameter of large hole machined end.
Carrying out in step deep hole machining process, the free end that processing is bored is fixedly mounted on the main shaft of machining tool, main shaft rotates, the aperture processing sections 203 first surface of the work of drill bit, the first blade 202 processes the aperture of bottom on workpiece, and that bores along with processing gos deep into, the second blade 211 on macropore processing sections 20 carries out large hole machined, so, when processing get into reach desired location time, can machine.
