Description
Technical field
The present invention relates to the tool holder mounting structure field of numerically controlled lathe, be specially a kind of centre-height adjustable type numerically controlled lathe knife rest drill point.
Background technology
At present, all kinds of numerically controlled lathes often run into the processing of boring, fraising class when batch machining part, are not suitable for using tailstock Manual drilling, fraising, need on numerically-controlled slide, fix drill bit, reamer etc. by mounting tool post drill point.The knife rest drill point using at present mostly can not be adjusted center cutter height, poor to the adaptation of lathe; The drill point that can adjust in addition centre-height all adopts dovetail groove guide frame, and manufacture difficulty is large, and required precision is high, uses inconvenient.
Summary of the invention
For the problems referred to above, the invention provides a kind of centre-height adjustable type numerically controlled lathe knife rest drill point, it can adjust the centre-height of cutter, and is convenient to manufacture, easy to use and strong adaptability.
A kind of centre-height adjustable type numerically controlled lathe knife rest drill point, its technical scheme is such: it comprises drill point piece, on described drill point piece, be provided with drill bit installing hole, trip bolt runs through after the upper surface of described drill point piece deeply to described drill bit installing hole, it is characterized in that: the lower surface of described drill point piece front side supporting part is inclined-plane, bottom, this side bottom inclined-plane of described drill point piece is supported on the ramp of wedge, one end of described drill point piece has the screwed hole that level is inwardly arranged, adjusting screw thread connects and is plugged in described screwed hole, the head of described adjustment screw exposes to described screwed hole, the head lower end of described adjustment screw is installed in the upper end notch of described wedge, the middle part of described wedge is furnished with waist type groove, described waist type groove is arranged along the direction of feed of described adjustment screw, anti-drop screw runs through the inclined-plane, bottom that is anchored on described drill point piece after described waist type groove from bottom to top.
It is further characterized in that:
The inclined-plane, bottom of described drill point piece, the ramp of wedge are identical with the formed angle of horizontal plane, are α, and the scope of α is 2 °～7 °;
Described waist-shaped hole is specially countersunk head formula waist type groove, and its below that is specially described waist type groove has rectangular groove, and the lower end portion of described anti-drop screw is positioned at described rectangular groove;
Described drill bit installing hole can be also Morse taper shank hole.
Adopt after this novel technical scheme providing, on drill point piece, be screwed with adjustment screw, by adjusting back-outing of screw, be screwed into promote the front and back position of wedge, thereby the variation of wedge position has changed the fix a cutting tool centre-height of installing hole of drill point piece, wedge and drill point piece are spacing with anti-drop screw, prevent the separated loss of each part when not using knife rest drill point; It only needs one and adjusts the adjustment up and down that screw just can be realized elevation of the cutter center while using, easy to use; Adopt the wedge angle of wedge less, adjust screw adjustment precision high, easily reach user to the high-precision requirement in center; To sum up, it can adjust the centre-height of cutter, and is convenient to manufacture, easy to use and strong adaptability.
Accompanying drawing explanation
Fig. 1 is that figure is blown in stereogram assembling of the present invention.
Fig. 2 is assembling section of the present invention.
the specific embodiment:
See Fig. 1, Fig. 2, it comprises drill point piece 1, on drill point piece 1, be provided with drill bit installing hole 6, trip bolt 4 runs through after the upper surface of drill point piece 1 deeply to drill bit installing hole 6, the lower surface of drill point piece 1 front side supporting part is inclined-plane, bottom 7, this side bottom inclined-plane 7 of drill point piece 1 is supported on the ramp 8 of wedge 2, one end of drill point piece 1 has the screwed hole 9 that level is inwardly arranged, adjusting screw 3 is threaded and is plugged in screwed hole 9, the head of adjusting screw 3 exposes to screwed hole 9, the head lower end of adjusting screw 3 is installed in the upper end notch 10 of wedge 2, the middle part of wedge 2 is furnished with waist type groove 11, waist type groove 11 is arranged along the direction of feed of adjusting screw 3, anti-drop screw 5 runs through the inclined-plane, bottom 7 that is anchored on drill point piece 1 after waist type groove 11 from bottom to top, the inclined-plane, bottom 7 of drill point piece 1, the ramp 8 of wedge 2 is identical with the formed angle of horizontal plane, be α, the scope of α is 2 °～7 °, this oblique angle is Self-locking angle, utilize frictional force self-lock mechanism, simple in structure, principle is reliable, waist-shaped hole 11 is specially countersunk head formula waist type groove, and its below that is specially waist type groove has rectangular groove 12, and the lower end portion of anti-drop screw 5 is positioned at rectangular groove 12.Drill bit installing hole 6 can be also Morse taper shank hole, more convenient use.
Its concrete assembling process is as follows: first by adjusting screw 3, be screwed in the screwed hole 9 of drill point piece 1, again the ramp of wedge 28 and the inclined-plane, bottom 7 of drill point piece 1 are adjacent to, and the upper end notch 10 of wedge 2 just blocks the head of adjusting screw 3, anti-drop screw 5 is screwed into drill point piece 1, the head of anti-drop screw 5 sinks in the countersunk head formula kidney slot of wedge 2, and anti-drop screw 5 is not tightened and just prevented that drill point piece 1 is separated with wedge 2.Drill bit, reamer, drill point handle can pack in the drill bit installing hole 6 of drill point piece 1, and are compressed by hold-down screw 4.As shown in Figure 2, only need be screwed into and adjust screw 3 and can promote the height that wedge 2 and drill point piece 1 move toward one another promote drill point piece 1, back-out and adjust screw 3 and can promote the height that wedge 2 and the opposing motion of drill point piece 1 reduce drill point piece 1.Press shown in Fig. 2, wedge 2 is designed to Self-locking angle with drill point piece 1 faying face and horizontal plane angle, and owing to adjusting the head of screw 3, by the upper end notch 10 of wedge 2, blocked, the thrust to whole drill point mechanism of knife rest can not allow wedge 2 and 1 relative motion of drill point piece.
