Before the present invention, the equipment of milling spiral groove, at first will carry out change gear and calculate and install in milling process based on universal milling machine, and is time-consuming; Secondly the angle of milling cutter and part is to be realized by the angle of regulating workbench on universal milling machine, because the machine tool structure restriction, the angular adjustment of workbench is subjected to certain limitation, and causes the knife bar elongation to have a strong impact on the milling rigidity; For above-mentioned reasons, make spiral fluted machining accuracy and fineness all be restricted; Debug difficulties especially under the situation of the many kinds of a machine, many specifications particularly, sometimes even can't realize; And this process is time-consuming, effort, and efficient is low.
Summary of the invention
Purpose of the present invention just is to overcome above-mentioned defective, designs a kind of numerically-controlled full-automatic spiral groove milling machine.
Technical scheme of the present invention is:
Numerically-controlled full-automatic spiral groove milling machine, main spindle box is on the vertical guide rail on the column, vertical feed mechanism connects main spindle box, workbench is installed on the cross slid platform, transverse feed mechanism connects workbench, cross slid platform is installed on the longitudinal rail of lathe bed front portion, longitudinal feed mechanism connects cross slid platform, automatic feeding is fixed on the workbench middle part, it is characterized in that column is installed on the mobile turntable, mobile turntable is installed on the guide rail at lathe bed rear portion, post adjustment mechanism is by worm screw, worm gear, screw mandrel, the feed screw nut constitutes, and worm gear is connected with the column bottom, and worm and wheel connects, screw mandrel is connected with the feed screw nut, and the feed screw nut is connected with mobile turntable bottom; The calibration clamping device toply is made of top, the top hydraulic cylinder of hydraulic pressure, NC dividing head, counter spending, top hydraulic cylinder is fixed on the workbench right side, top and the top hydraulic cylinder of hydraulic pressure is connected, and NC dividing head is fixed on the workbench left side, and counter spending toply is connected with NC dividing head.
The invention has the advantages that part calibration and whole milling parameter adopt digital control scheme, exempted the general numerous and diverse change gear of milling machine of using and calculated and install that reduced or remitted all machine tool accessories such as change gear, chuck etc., replacing kind and debugging are very convenient.
The angle that the present invention be advantageous in that milling cutter and part is realized by regulating the main shaft angle, need not extend knife bar, the milling rigidity is greatly improved, thereby improved spiral fluted machining accuracy and fineness greatly.Part feeding and clamping are carried out automatically by hydraulic circuit and programme-control, realize automated production, the efficient height, and labour intensity is low.
Other advantages of the present invention and effect will go on to say below.
Description of drawings
Fig. 1---front view of the present invention.
Fig. 2---vertical view of the present invention.
Fig. 3---post adjustment mechanism map of the present invention.
The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3:
Main spindle box 5 is installed on the column 4, and vertical feed mechanism 6 connects main spindle boxes 5, and main spindle box 5 contacts with vertical guide rail on the column 4 and is connected; Column 4 is installed on the mobile turntable 2, and mobile turntable 2 is installed on the guide rail at lathe bed 1 rear portion; Post adjustment mechanism 3 is made of worm screw 3.1, worm gear 3.2, screw mandrel 3.3, feed screw nut 3.4, and worm gear 3.2 is connected with column 4, and the position is at column 4 bottom centre place, and worm screw 3.1 is connected with worm gear 3.2; Screw mandrel 3.3 is connected with feed screw nut 3.4, and feed screw nut 3.4 is connected with mobile turntable 2, and the position is in mobile turntable 2 bottoms; Workbench 7 is installed on the cross slid platform 9, and transverse feed mechanism 8 connects workbench 7, and cross slid platform 9 is installed on the guide rail of lathe bed 1 front portion, and longitudinal feed mechanism 10 connects cross slid platform 9; The calibration clamping device is top 11 by hydraulic pressure, top hydraulic cylinder 12, NC dividing head 13, instead spend top 14 to constitute; Top hydraulic cylinder 12 is fixed on workbench 7 right sides, and top 11 are connected with top hydraulic cylinder 12; NC dividing head 13 is fixed on workbench 7 left sides, instead spends top 14 to be connected with NC dividing head 13; Automatic feeding is fixed on workbench 7 middle parts, and automatic feeding is made up of delivery sheet 15, feeding hydraulic cylinder 16, skid bed 17; Delivery sheet 15 is connected with feeding hydraulic cylinder 16, and skid bed 17 is positioned at the delivery sheet top.
Application process:
Before starting working, at first make worm gear 3.2 drive column 4 by the worm screw in the post adjustment mechanism 13 3.1 and clockwise rotate, the main spindle box 5 that is installed on the column 4 is rotated, milling cutter on the main spindle box 5 and part to be processed form the required angle of processing; Making feed screw nut 3.4 drive mobile turntable 2 by screw mandrel 3.3 then laterally moves right, makes milling cutter be positioned at the part processing scope; It is respectively that mobile turntable 2 and column 4 is fixing after adjusting finishes.By four-shaft numerically controlled system each machined parameters is set.
During work, at first feeding hydraulic cylinder 16 promotion delivery sheets 15 move ahead from right to left (as Fig. 1, hydraulic means does not draw, omit), when the part to be processed on the delivery sheet 15 is sent to calibration clamping device center, the top hydraulic cylinder 12 on calibration clamping device right side promotes top 11 part to be processed is pushed up counter spending in top 14 to the NC dividing head 13 in calibration clamping device left side, spend top 14 it is carried out self-centering and hold out against (as Fig. 2) by counter, delivery sheet 15 is return, and the next part in the skid bed 17 falls into the groove of delivery sheet 15 front ends; Then, the milling cutter on the main spindle box 5 is rotated counterclockwise and is descending along the vertical guide rail of column 4 by vertical feed mechanism 6, finishes vertical feed, reaches milling depth; 7 of workbench drive part to be processed by transverse feed mechanism 8 and move right, and finish traverse feed, and NC dividing head 13 spends top 14 drive parts to be processed to be rotated counterclockwise by helix lead by counter simultaneously; Make the helix of movement locus for setting of part to be processed and milling cutter by the rotary speed of four-shaft numerically controlled system (omit among the figure, do not draw) control NC dividing head 13 and the traverse feed speed of angle and workbench 7, thereby finish the full-automatic milling of helicla flute.Milling finishes, and top 11 of calibration clamping device right side retreats, and part falls into conveyer belt (conveying device is not drawn, and omits), and main spindle box 5, workbench 7 and calibration clamping device recover original position, and next part processing begins, repeatedly circulation.
In milling process, workbench 7 can be made vertical poor benefit by 10 pairs of milling process of longitudinal feed mechanism, finishing the milling of special shape spiral fluted, as processing of tapering milling cutter etc.
