Description
Technical field
The present invention relates to a kind of servo-actuated boring machine, particularly a kind ofly process the servo-actuated boring machine that crooked pipe is used.
Background technology
Present general boring machine adds man-hour carrying out deep hole boring, is to guarantee machining accuracy, and boring head has bushing to lead, between boring bar and the boring head for being rigidly connected, therefore in the boring head process, can guarantee to stablize feeding workpiece inwall both sides processing capacity uniformity along axis of workpiece.
But, for crooked pipe, adopt general boring machine to carry out boring processing, because boring bar and boring head be for being rigidly connected, in the process, boring head along continuous straight runs feeding all the time will cause the circumferential processing capacity of pipe endoporus inconsistent like this.
The bimetallic pipe is in casting process, because the defective of technology itself, pipe can produce buckling phenomenon; The subsequent machining technology of casting pipe is mainly extruding and rolling, and when adopting extrusion process, the deformation ratio of workpiece is big, its length requirement to pipe is also shorter, often about 500mm, in carrying out boring processing endoporus process, the degree of crook of pipe is very little to the processing influence; But adopt the oblique milling workpiece to add man-hour, oblique roll process is less in the deformation ratio because of this process workpiece for the flexibility requirement of pipe, and pipe length is longer, and flexibility makes a big impact for the boring processing of endoporus.And bimetallic pipe internal diameter is valuable alloy, costs an arm and a leg, and adopts common boring machine to carry out price, can cause very big waste.
Summary of the invention
The technical issues that need to address of the present invention provide a kind of servo-actuated boring machine, and the uneven deficiency of base cutting when overcoming common boring machine processing swan-neck inwall guarantees workpiece endoporus sidewall processing capacity uniformity.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: its structure comprises machine tool chief axis, boring bar case, it is characterized in that: described machine tool chief axis connects the flexible combination boring head, the flexible combination boring head comprises the prelocalization mould, prelocalization mould front end cylinder lever connecting rod, and the pull bar other end connects the boring bar case, the prelocalization mould tail end boring cutter that is connected, the boring cutter tail end connects universal joint, and the universal joint tail end connects guide post, and guide post connects machine tool chief axis.
Further improvement of the present invention is:
Described boring cutter sidewall is established feather key.
Described guide post and main shaft lead key are connected.
Prelocalization mould cylindrical is uniform protruding stupefied.
The cutting edge of boring cutter is symmetrically distributed on circumference, and according to processing caliber difference, cutting edge can be designed as 4,6,8 or 12.
Because the technological progress of having adopted technique scheme, the present invention to obtain is:
The present invention adopts the flexible combination boring head, its prelocalization mould closely contacts with the pipe inwall, the pipe flexibility can be passed to boring cutter, guarantees that boring cutter is done boring processing along crooked pipe axis in the process, processing capacity is even around the tube wall, and the prelocalization mould is close to the pipe inwall, can pass to boring head to the flexibility of pipe well, realizes servo-actuated processing, boring cutter is adorned 4,6,8 or 12 cutting edges according to the size of diameter of work, multitool boring simultaneously, stressed even, cutting is stable.
Description of drawings
Fig. 1 is a kind of flexible combination boring head structural representation of servo-actuated boring machine.
Wherein: 1, pull bar, 2, the prelocalization mould, 3, boring cutter, 4, feather key, 5, universal joint,
6, guide post, 7, cutting edge.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in further details:
Shown in Figure 1, the present invention includes machine tool chief axis, the boring bar case, machine tool chief axis connects the flexible combination boring head, the flexible combination boring head comprises prelocalization mould 2, uniform protruding stupefied on prelocalization mould 2 cylindricals, prelocalization mould 2 front end cylinder lever connecting rods 1, pull bar 1 other end connect the boring bar case, the prelocalization mould 2 tail ends boring cutter 3 that is connected, boring cutter 3 sidewalls are established feather key 4, the cutting edge 7 of boring cutter 3 is symmetrically distributed on circumference, and according to processing caliber difference, cutting edge can be designed as 4,6,8 or 12, boring cutter 3 tail ends connect universal joint 5, universal joint 5 tail ends connect guide post 6, and guide post 6 connects machine tool chief axis, and guide post 6 is connected with the machine tool chief axis lead key.
The present invention adopts the flexible combination boring head that universal joint+special-purpose boring head forms to substitute fixedly boring head of original common boring machine, workpiece maintains static, the flexible combination boring head is done rotation and feed motion, and machine tool chief axis power passes to boring cutter 3 by universal joint, carries out boring processing by pull bar traction boring cutter 3; Prelocalization mould 2 closely contacts with the pipe inwall, can well the pipe flexibility be passed to boring cutter 3, guarantees that boring cutter 3 is done boring processing along crooked pipe axis in the process, and processing capacity is even around the tube wall.
Pull bar 1 is drawn by the boring bar case, be connected with prelocalization mould 2 by bearing pin, prelocalization mould 2 and boring cutter 3, universal joint 5 and guide post 6 are formed the flexible combination boring heads, and guide post 6 cooperates by keyway on it and the key on the main spindle box axle sleeve, and the rotary power of main shaft is passed to the flexible combination boring head.
The present invention has adopted a prelocalization drawing-die 2 of not rotating, and its outer wall has protruding stupefied, if caliber changes too greatly or pipe is surperficial obvious projection and pit is arranged, and can utilize 2 pairs of workpiece of prelocalization drawing-die to carry out preprocessing earlier, makes the pipe diameter of bore be gradual change trend.
Prelocalization mould 2 and caliber have certain magnitude of interference, boring cutter 3 can make bore generation plastic deformation when being drawn by brute force, prelocalization mould 2 can stable being fixed in the pipe, draws can reduce pulling force and can the boring turning centre instantaneous change not occur when abrupt changes in diameter again, effectively reduces tool damage; And prelocalization mould 2 is close to the pipe inwall, can pass to boring head to the flexibility of pipe well, realizes servo-actuated processing.
Draw the back borer to make mode before this machine adopted, need unload boring head when changing workpiece, adopt the fast-assembling hook can load and unload boring head quickly and easily.Universal joint 5 driving torque that does as usual in the time of can allowing boring head with curved boring.Boring cutter 3 can be adorned 4,6,8,12 cutting edges 7 according to the size of diameter of work, realize multitool boring simultaneously, stressed even, cutting is stable, be right after boring cutter 3 rear ends feather key 4 is housed, feather key 4 is made by carbide alloy, and effect is with hole, the garden centering after the workpiece cutting, the other end of sliding support boring cutter 3, the skew vibrations of control boring cutter 3, guarantee the normal of cutting, feather key is furnished with the different adjusting pad of size for 4 times, guarantees that the diameter in the garden that feather key 4 is formed is consistent with the diameter in cutting garden.
During general boring steel cuttings from the cutting end row of workpiece to cutting end not, the close not cutting end of boring head of the present invention is a pilot centering mechanism, will cause to cutting end chip removal not from the cutting end again and squeeze bits, make smear metal normally not carry out, so this Machine Tool design chip removal mode is for never cutting the chip removal of end grain cutting end.
