SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to above-mentioned defect, but a novel numerical control boring cutter is provided to solve boring cutter and adjust the loaded down with trivial details inefficiency of work, accurate rate low and the little problem of range of working.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a novel but numerical control boring cutter, includes bore hole aircraft nose and boring bar, bore hole aircraft nose fixed connection control motor, the output shaft fixed connection control lead screw of control motor, the control lead screw left end is equipped with the fixture block, fixture block fixed connection skewed tooth rack right-hand member, be equipped with transverse guide and vertical guide in the boring bar, the skewed tooth rack passes through transverse guide sliding connection boring bar, the boring bar passes through vertical guide sliding connection skewed tooth cutter arbor, the skewed tooth rack outside is located and is equipped with return spring between boring bar and the fixture block.

As a further proposal of the utility model, the boring bar is fixedly connected with the boring machine spindle.

As a further aspect of the present invention, the boring machine spindle is fixedly connected to the boring head.

As a further proposal of the utility model, helical teeth with the same angle are processed on the helical rack and the helical cutter bar.

As a further aspect of the present invention, the control motor is a forward/reverse rotation control motor.

To sum up, compared with the prior art, the utility model has the following beneficial effects:

programming according to a part to be processed, programming a control motor by a numerical control system, driving a control screw rod to rotate forwards by the control motor when the control motor rotates forwards, converting rotary motion into linear motion by the control screw rod and pushing a helical rack by a fixture block, axially moving the helical rack in a transverse guide rail in a boring bar to push a helical cutter bar, moving the helical cutter bar upwards along a vertical guide rail to achieve the aim of adjusting the cutter, driving the control screw rod to rotate backwards by the control motor when the control motor rotates backwards, converting rotary motion into linear motion by the control screw rod and moving the helical rack rightwards, driving the fixture block to move rightwards by a return spring to drive the helical rack to move rightwards, pulling the helical cutter bar by the axial motion of the helical rack in the transverse guide rail in the boring bar, moving the helical cutter bar downwards along the vertical guide rail, thereby being capable of flexibly changing the length of the boring cutter at any time under the control of the numerical control motor, the boring tool adjusting device has the advantages of simple and convenient boring tool adjusting work, high efficiency, high precision and large processing range.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention based on the embodiments of the present invention.

Example 1

Shown by fig. 1-2, a novel but numerical control boring cutter, including boring aircraft nose 1 and boring bar 2, boring aircraft nose 1 fixed connection control motor 7, control motor 7's output shaft fixed connection

control lead screw

6, 6 left ends of control lead screw are equipped with fixture block 9, 3 right-hand members of fixture block 9 fixed connection skewed tooth rack, be equipped with transverse guide 101 and vertical guide 102 in the boring bar 2, skewed tooth rack 3 passes through transverse guide 101 sliding connection boring bar 2, boring bar 2 passes through vertical guide 102 sliding connection skewed tooth cutter arbor 4, boring bar 2 fixed connection boring machine main shaft 8, boring machine main shaft 8 fixed connection boring aircraft nose 1.
