Technical field
The utility model relates to numerically controlled lathe, specifically, relates to a kind of improved numerically controlled lathe lathe bed.
Background technology
Numerically controlled lathe, turning center are a kind of high accuracy, high efficiency automated machine tool.Be equipped with multistation cutter tower or power cutter tower, lathe just has process performance widely, but complex parts such as processing linear cylinder, oblique line cylinder, circular arc and various screw thread, groove, worm screw.Domestic existing numerically controlled lathe equipment structure is made up of head of a bed gearbox, lathe bed, side leading screw, tailstock and drive motors.Because leading screw is arranged on the side of the body of lathe bed, the operation of big palette since the side leading screw to lead the power of dragging too big, the supporting plate sideslip causes the excessive injury of flank wear to lathe bed easily, has also increased the deviation of processing dimension.Torsional deformation deviation appears, in rail location, original single mountain inaccuracy easily.In addition, head of a bed gearbox connects main shaft, breaks down easily, and noise is big, and maintenance cost increases, and causes cost to rise.
Summary of the invention
The technical problem that the utility model will solve is to overcome above-mentioned defective, provides a kind of and improve machining accuracy, avoids the improved numerically controlled lathe vehicle body that injures lathe bed, reduce noise pollution and reduce production costs.
For addressing the above problem, the technical scheme that the utility model adopted is:
A kind of improved numerically controlled lathe lathe bed comprises lathe bed, and the middle part of lathe bed is equipped with drive motors; The top of lathe bed is provided with outer casing; It is characterized in that: two upper lateral parts of said lathe bed slidely connect big palette for two mountains rail, two mountains rail upper end, and the below of big palette is provided with transmission mechanism; The upper surface of big palette is provided with widens middle supporting plate, and the upper surface of supporting plate is equipped with knife rest in widening; Said lathe bed is provided with independent spindle motor, and independent spindle motor is connected with independent main shaft, and independent main shaft is installed in the lathe bed upper end through the head of a bed.
Say further:
Said transmission mechanism comprises the mid-leading screw that is arranged on the lathe bed middle part, and mid-leading screw one end and drive motors are in transmission connection, and the bottom face of big palette is connected with mid-nut seat, and mid-nut seat is connected with mid-threads of lead screw.
Further say:
The inboard of said pair of mountain rail is provided with tailstock.
Said independent spindle motor is servomotor or variable-frequency motor.
Two side bottoms of said big palette are provided with the wedge shape adjuster.
Be respectively arranged with the increasing bearing on the head of a bed at said lathe bed two ends, strengthen bearing and be connected with independent collar bush.
Owing to adopted technique scheme, compared with prior art, be designed with two mountains rail in the utility model, two mountains rail cooperates with big palette, and the location accurately is not prone to deviation, is difficult for producing torsional deformation, and the design of mid-leading screw has significantly reduced mismachining tolerance.In addition, control independent main shaft with variable-frequency motor or servomotor, fault rate is low, and maintenance rate is low, has practiced thrift the great amount of manpower financial resources, has reduced production cost.Also have, be provided with the wedge shape adjuster, be used for the level and parallel adjustment of various device, make equipment in operation process, not shake, tilt, guarantee the good operation of machine, reduce wear and tear in machines, the assurance device security at two side bottoms of big palette.
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further simultaneously.
Description of drawings
Accompanying drawing is the structural representation of a kind of embodiment of the utility model.
Among the figure: the 1-drive motors; The mid-leading screw of 2-; The two mountains of 3-rail; The 4-outer casing; Supporting plate among the 5-; 6-independence spindle motor; 7-independence main shaft; The 8-big palette; The 9-tailstock; 10-wedge shape adjuster; The mid-nut seat of 11-; 12-strengthens bearing; The 13-tool rest.
The specific embodiment
Embodiment:
A kind of improved numerically controlled lathe lathe bed shown in accompanying drawing, comprises lathe bed, and the bottom of lathe bed is equipped with drive motors 1, and the outside of lathe bed is equipped with outer casing 4.Said lathe bed two upper lateral parts are provided with two mountains rail 3, and rail 3 upper ends, two mountains slidely connect big palette 8, and the below of big palette 8 is provided with transmission mechanism, are fixed with on the upper surface of big palette 8 to widen middle supporting plate 5, on the upper surface of supporting plate 5 tool rest are installed in widening.In the present embodiment, tool rest is electronic or the hydraulic pressure tool rest.Two mountains rail 3 cooperates with big palette 8, and the location accurately is not prone to deviation, is difficult for producing torsional deformation, to improve the quality of processing.In addition, rail inboard, two mountain is provided with tailstock 9, has increased the stability of big palette, has improved machining accuracy.
