Description

A kind of four horizontal digital-control boring-milling machines

Technical field

The utility model relates to field of mechanical technique, specifically a kind of four horizontal digital-control boring-milling machines.

Background technology

At present, existing four horizontal boring and milling machines such as horizontal Machining centers, its structure is mainly: unit head and slide plate fix, and slide plate is installed on the column guide rail, drives slide plate by the transmission of driven by servomotor ball screw and moves up and down, and is called Y-axis; And column is installed on the Mobile Slide, moves forward and backward by driven by servomotor ball screw transmission drive slide unit body to be called the Z axle; Workpiece is installed on another horizontal direction Mobile Slide, drives slide unit body move left and right by the transmission of driven by servomotor ball screw and is called X-axis; Panoramic table is installed on the Z axle slide unit body, realizes gyration, is called the B axle.Because unit head is installed on the column by slide plate, narrow between its space empty, the Z axle is to move by moving forward and backward of column in addition, so the rigidity of unit head and column is relatively poor, be only applicable to little surplus high-speed cutting processing, and the retentivity of cutting precision is lower.

The utility model content

Technical problem to be solved in the utility model is, at the deficiencies in the prior art, provide a kind of rational in infrastructure, improve cutting rigidity and precision stability, be applicable to four horizontal digital-control boring-milling machines of big surplus high-rate cutting.

The technical scheme that its technical problem that solves the utility model adopts is: it comprises base, X-axis slide unit, B axle panoramic table, column and unit head; The X-axis slide unit places on the slide rail of base, and the X-axis slide unit links to each other with the X-axis motor, so that the X-axis slide unit is realized horizontally slipping; The B axle panoramic table of laying workpiece is loaded on the X-axis slide unit by the longitudinal axis, and B axle panoramic table links to each other with the B spindle motor, so that B axle panoramic table can rotate around the longitudinal axis; Column is fixed on the base; The axial unit head of Z is fixed on the ram head, and an end of ram head is loaded in the guide rail, and the ram head links to each other realization unit head Z-motion with the Z spindle motor; Guide rail is nested with on the Y-axis leading screw spacing by column of two ends up and down by screw thread, and the Y-axis leading screw links to each other with y-axis motor, only rotate and do not move up and down to drive the Y-axis leading screw, but guide rail only moves up and down and do not rotate, thereby the drive unit head is made Y-motion.

The following rail width of above-mentioned guide rail to improve rigidity, bearing and the anti-disturbing moment ability of guide rail, strengthens the stability of cutting precision greater than last rail width.

The outside of above-mentioned rail down surpasses the center of ram head, promptly descends the centre-to-centre spacing of the width of rail greater than the horizontal direction of ram head.

The beneficial effects of the utility model are: since column fixedly install and unit head adopts the motion structure of ram gib and lead screw transmission, thereby rigidity and bearing have been improved effectively, and anti-disturbing moment ability is strong, the machining accuracy good stability is particularly suitable for big surplus high-rate cutting processing.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further specified.

The utility model comprises base 1, X-axis slide unit 2, B axle panoramic table 5, column 12 and unit head 11; X-axis slide unit 2 places on the slide rail of base 1, and X-axis slide unit 2 links to each other with X-axis motor 4 by X-axis leading screw 3, so that 2 realizations of X-axis slide unit horizontally slip; The B axle panoramic table 5 of laying workpiece is loaded on the X-axis slide unit 2 by the longitudinal axis 6, and B axle panoramic table 5 links to each other with B spindle motor 8 by belt 7, so that B axle panoramic table 5 can be around the longitudinal axis 6 rotations; Column 12 is fixed on the base 1; The axial unit head 11 of Z is fixed on the ram head 9, one end of ram head 9 is loaded in the guide rail 10, the following rail 10-2 width L1 of guide rail 10 is greater than last rail 10-1 width L2, the outside of following rail 10-2 surpasses the center of ram head 9, promptly descends the centre-to-centre spacing H of the width L1 of rail 10-2 greater than the horizontal direction of ram head 9; And ram head 9 links to each other with Z spindle motor 17 by belt 16, realizes that unit head 11 realization Z axially seesaw.Guide rail 10 is nested with on the Y-axis leading screw 15 spacing by column 12 of two ends up and down by screw thread, Y-axis leading screw 15 links to each other with y-axis motor 13 by belt 14, to drive 15 rotations of Y-axis leading screw and not move up and down, but 10 on guide rail moves up and down and does not rotate, and makes Y-axis and moves up and down thereby drive unit head 11.
