In order to reach the numerical control purpose of processing automatically, each execution unit of numerically controlled lathe is controlled execution by numerical control program, and the flow process of numerical control program is as follows:
S1, chuck assembly unclamp, and pay-off clamping bar is by the centre bore feeding of chuck assembly;
After the detecting element perception feeding in S2, chuck assembly the place ahead put in place, pay-off unclamped bar and returns; After chuck assembly was held described bar tightly simultaneously, toolbox was finished the processing of bar end face, cylinder;
S3, toolbox begin to cut off bar, and the tube that connects material of the unit that connects material stretches out to bar;
S4, Cutting stick, the unit that connects material connects material and recalls.
After this, circulation repeats above-mentioned steps S1-S4.
Below in conjunction with accompanying drawing 1-7, highlight the unit that connects material of numerically controlled lathe, and the process of numerically controlled lathe.
At first, as shown in Figure 1, each device is in the state of initial position on the lathe, comprising the bar anchor clamps 1 that are arranged in the left side among the figure, the anchor clamps 2 that the figure right side is used for the clamping cutter.The middle part of anchor clamps 1 is provided with through hole, be used for bar from rear side A to sending into, and deliver to anchor clamps 1 right side, realize anchor clamps 2 fix a cutting tool 5,6 processing, cut-out.In addition, lathe also comprises the unit that connects material that is positioned at anchor clamps 2 opposite anchor clamps 1 one sides among the figure.This unit that connects material is included in the tube 4 that connects material that moves back and forth under the gear unit effect; And the positioning sleeve 3 that wears the tube 4 that connects material.Among Fig. 1 embodiment, the unit 16 that connects material comprises the tube that connects material, and a bottom that connects material is driven the base that moves back and forth by gear unit.
The tubular construction that the tube 4 that connects material is opened for the front and back end.Operational phase, positioning sleeve 3 is motionless, and the tube 4 that connects material is done linear reciprocation and is moved in cover.Under the optimal way, tube 4 unit that move of realizing connecting material are selected hydrostatic transmission module for use.The rear end discharging opening of tube of connecting material is provided with sloping type groove 1 (shown in Figure 1), and extends to the storing district, thereby does the position that accurately machined bar is sent to next manufacturing procedure.
The processing method of lathe, with reference to Fig. 2-step shown in Figure 5. wherein, shown in Figure 2, cutter 5 moves to bar alignment of shafts place, and the feed arrangement (not shown) is blocked bar 9 in the left side of anchor clamps 1 pusher by cutter, thereby determine the length that bar 9 is to be processed. after this change Fig. 3 process segment over to, realize bar facing processing as shown in Figure 3, and the turning of bar cylindrical processing, realize by cutter 5.
After this change Fig. 4 stage over to, realize the rupturing operation of bar by cutter 6.The tube that connects material of unit of connecting material this moment 4 is delivered to bar front end place under the gear unit effect, and the bar front end stretches in the tube hole of the tube 4 that connects material.After cutter 6 cut off bar, cut-off parts fell into the tube 4 that connects material automatically.At this moment, if the tube that connects material is the setting that recedes, then the bar of Qie Duaning can slide to the rear end of tube 4 that connects material automatically, and skids off the tube that connects material, and falls into the groove that connects material.In this cut-out, under the optimal way, also can utilize cutter 6 to realize the chamfering operation of bar.
At last, enter the stage of Fig. 5, Fig. 5 is same as shown in Figure 2, and difference is to connect material the bar of cut-out in the tube.At this moment, the tube that connects material is recalled, and cutter moves to alignment of shafts place, and the feed arrangement pusher is blocked bar by cutter, determines the bar extension elongation, prepares processing next time.Then, repeat the step of above-mentioned Fig. 2-Fig. 4.Non-being obliquely installed of tube if connect material, then previous cut bar ejects from the tube hole, rear end of the tube 4 that connects material under follow-up cut bar effect, falls into the finished product district or the groove that connects material, and finishes final processing.
In addition, the unit that connects material is in the bar process segment, and in order to prevent machining interference, the tube that connects material need return to state shown in Figure 6; And in the cut-out stage, the tube that connects material in the unit that connects material is in and stretches out the dress attitude.Positioning sleeve 3 is in stationary state among the figure, and its effect is intended to for the tube that connects material provides the mobile guide effect, and a positioning action that connects material; Therefore positioning sleeve also can select for use other structures to realize, for example Gu Ding runner device or the like.
Numerically controlled lathe can be finished the processing of six meters long bars automatically, reaches the purpose that realizes the lathe High-speed machining.
Specifically, at first, hold main " O " type circle method that adopts of material unit design and come the restricted quarter free degree (especially being fit to the blank material is the round bar of six meters long diameter 30-50 millimeters).The bottom is supported with " V " type seat, is the friction of round bar to " V " type seat for fear of rotation simultaneously, has increased cylindrical roller during design on the hypotenuse of " V " type seat, or the cambered surface cylindrical roller, replaces sliding friction with rolling friction.And top is adopted retractable structure and is had locking member.Mid portion at first movable rack is equipped with unsteady roller.Ralocatable mode also can be assembled spring in the sliding eye of roller bracket, the floating roller that adds the first half in man-hour is adjusted to the distance of surface lies blank round bar surface 1-2MM, this is stuck in order to prevent machinery, the feeding part can't drag, like this in that if to add the man-hour whipping too big, the roller that then floats can borrow spring force that it is cushioned, thereby makes it can cut (speed can reach more than per minute 2000 commentaries on classics) in stable rotation under the high speed.
Secondly, pay-off is improved.In order to improve the efficient of work, in feeding, though chuck unclamp, but chuck still is being in the state of low speed rotation.For addressing this problem, retained part has been installed the roller that has two groups of " V " type pieces, and two groups of " V " type pieces are the frictional force that drags round bar in order to increase, and increases roller and then be when the blank material rotates the friction to two groups of " V " type pieces.The sequence of movement of material loading process is as follows: 1 material folding partly clamps, 2 chucks unclamp, 3 feeding part feedings, 4 chucks clamp once more, 5 material foldings are partly unclamped, (above action all is to provide power by hydraulic part) partly return in 6 feedings.Because of the moment of retained part when clamping, chuck does not also unclamp, and this moment can produce very big frictions with two groups of " V " type pieces, and the roller that increases in " V " type piece is just in order to eliminate this friction.
Once more, position detection unit is set.Because of round bar send to can not be unlimited after the main shaft down give, so need the localization part of increase round bar.On saddle, increase positioner during design, because of round bar and chuck when feeding break away from but owing to inertia, the rotation that also can keep low speed, so the front end of positioner has increased rotating part (having increased by one group of thrust bearing in the inside of swivel head), with guarantee can friction positioning device at the round bar of when location rotation the surface.When the round bar contact positioning device reached rated pressure, pressure switch can send signal, and signal feedback begins to carry out down the step action to system.
At last, set up automatic material connection unit (power is provided by hydraulic pressure). according to the characteristics of lathe and bearing roller, (near a side of tailstock) increased the automatic material connection unit in the planker back. when treating that cutter is carried out before the cut-out action, system can provide signal, tube action forward connects material, entangle workpiece, at this moment, the part major part that is about to process is entangled, and meanwhile cutoff tool begins to cut off, cut off the back system and provide signal, sleeve returns to original position, and the part that process this moment has been stayed the sleeve the inside. reciprocating action several times, after sleeve is full, then new parts can be with in the part jacking discharge chute that processes at first, until slipping into hopper.
The above; only be the preferable specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
