Description
Technical field
What the present invention relates to is a kind of portal frame feed and precision dividing apparatus, and particularly a kind of portal frame feed and precision dividing apparatus of processing giant-screen template lathe belongs to mechanical engineering field.
Background technology
The fiberglass giant-screen has plurality of specifications, and its maximum is of a size of 3.2m * 2.4m; It has two types striped: one is linear arc-shaped striped, spacing 0.2mm, dark 0.15mm (or other shape striped of straight line, decide by designing requirement); It two is a concentric circles triangle striped, spacing 0.5mm, dark 0.3mm (or other shape striped of concentric circles).Produce the fiberglass giant-screen of above-mentioned striped, at first will have the lathe of the aluminium alloy template that can process above-mentioned shape of stripes.This lathe should have the function of vertical lathe, and turntable is rotated, by shaped profile turning cutter processing concentric circles triangle striped; Plane, milling function are arranged again.When turntable maintains static, move to (vertically) along guide rail X by portal frame, drive profile milling cutter and rafting moving processing linear arc striped.But also to have high-precision indexing mechanism make linear fringe (or the concentric circles striped) interval error that processes remain on ± 0.004mm between.Analyze by literature search, find Chinese patent application numbers 95215895.7, name is called the special-purpose simple and easy Longmen machine tool of watt supporting-point roller, readme is the mainframe of four leg formulas of bag Chinese juniper, its two level and smooth horizontal slide rails of having put on the shelf, the head that slides along slide rail is fixed on the crossbeam of slide rail end adjustable for height movable frame on the head main support, the assembly that the wheel of milling is arranged, the ratio wheel assembly.It is mainly used in processing corrugation roller, though it finishes the Milling Process task by the head lengthwise movement, can not infinitely variable speeds, and can not precision indexing, can not pull by the machining large mould.So far do not find that car adds removable portal frame on vertical lathe, realize the large-scale metal form machining tool of wound, milling.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, on lathe, design cover portal frame feed and a precision dividing apparatus, can realize digging, the function of the fine and closely woven striped of milling straight line with vertical lathe function.This lathe is fixed at turntable, when portal frame drives blade row and moves, can be on template processing linear arc striped.Can adapt to the different linear stripe patterns of milling by infinitely variable speeds, show the horizontal scale division value of measuring blade row, realize the precision indexing of blade row by the grating chi.The present invention makes has increased plane, milling function on the vertical lathe, can process giant-screen template linear on a machine tool, the circular concentric striped.The can be mass-produced fiberglass giant-screen of various stripeds of the various templates that process.Provide cost savings greatly and filled up blank for processing giant-screen template lathe.
The present invention is achieved by the following technical solutions, device of the present invention mainly comprises the vertical adjustable speed synchronous moving mechanism of portal frame, the horizontal precision indexing of saddle mechanism, upper slide rest is vertically to travel mechanism, the vertical adjustable speed synchronous moving mechanism of portal frame is arranged on the lathe bed, and portal frame can be made infinite variable speed straight line along bed ways and move; The horizontal precision indexing of saddle mechanism is arranged on the crossbeam, and saddle can be made horizontal straight line and move on crossbeam, shows the horizontal scale division value of measuring blade row by the grating chi, realizes the precision indexing of blade row; Upper slide rest vertically is arranged on the saddle to travel mechanism, and upper slide rest can be done vertically to move to straight line on saddle.By the grating chi show to measure control milling cutter row vertically to displacement t, just can guarantee cutter vertical feed accuracy of measurement.
The course of action of the vertical adjustable speed synchronous moving mechanism of portal frame is: driven by the adjustable speed direct current generator, go out to take out worm reducer by two, worm reducer by a pair of identical gearratio is split into two identical rotating speeds of two sides to a certain rotating speed of direct current generator again, reach two side turn-screws are rotated synchronously, thereby the drive portal frame is made synchronous straight line and is moved on two side bed ways, because direct current generator can stepless speed regulation in gearratio i=10 scope, through deceleration transmission, so portal frame can divide to step-less adjustment between the 180mm/ branch at 18mm/ along the translational velocity of bed ways, can adapt to the multi-form linear fringe of processing, the needs of different feed line of motion speed.Saddle (blade row) the laterally course of action of precision indexing mechanism is: by manually or and manoeuvre, by worm reducer and lead screw transmission, make saddle and top blade row thereof make laterally (Y to) dividing movement along crossbeam, the slip-on head of grating chi is housed on the saddle, so the amount of movement of saddle (blade row) can be surveyed by the grating chi and show, its certainty of measurement is at ± 0.004mm, the requirement of the precision indexing in the time of so just can satisfying thousands of linear stripe patterns of milling cutter processing.The course of action of upper slide rest (blade row) vertical movement mechanism mechanism is: driven by stepper motor, by worm reducer and lead screw transmission, upper slide rest is done vertically to moving along saddle, thereby the milling cutter row who is cemented on the upper slide rest is also done vertically to moving, the slip-on head of grating chi is housed on the upper slide rest, so the amount of movement of upper slide rest (blade row) can be surveyed by the grating chi and show, its certainty of measurement is at ± 0.004mm, the requirement of the accurate measurement of vertical feed amount t in the time of so just can satisfying thousands of linear stripe patterns of milling cutter processing, revolution (umber of pulse) by the control step motor, just can control milling cutter row vertically to displacement t, just can guarantee the precision of cutter vertical feed amount, the fringe depths that makes each bar that processes on the template is within certain error range.Lathe of the present invention is when turntable fixedly the time, the vertical adjustable speed synchronous moving mechanism of portal frame drives portal frame and implements the length feed motion, saddle (blade row) laterally precision indexing mechanism driving blade row is implemented horizontal precision indexing, show the horizontal scale division value of measuring blade row by the grating chi, realize the precision indexing of blade row.Upper slide rest (blade row) vertical movement mechanism drives blade row and implements vertically to accurate feed campaign.The present invention makes on the basis of original vertical lathe function has increased plane, milling function, can process giant-screen template linear on a machine tool, the circular concentric striped.
The present invention has substantive distinguishing features and marked improvement, mill at common gantry is that the workbench band workpiece and vertically moved, portal frame is solid motionless, employing has the device of structure of the present invention, on the basis of former vertical lathe, turntable is fixed, portal frame has along X and moves the function of feed to (vertically) infinitely variable speeds, the horizontal raster chi is surveyed, show, the sulphur of control blade row is to amount of movement, realize the horizontal precision indexing of blade row, the requirement of the precision indexing in the time of so just can satisfying thousands of linear stripe patterns of milling cutter processing, vertically the grating chi is surveyed, show, the length feed amount t of control blade row, the precision of assurance cutter vertical feed amount, the fringe depths that makes each bar that processes on the template is within certain error range.Apparatus of the present invention can be saved gantry of gantry interior span 3.5m and be milled (or double housing planer).Saved production cost greatly.And for processing giant-screen template lathe has been filled up blank.
