The present invention relates to a kind of grinding machine, particularly a kind of planer type numerical control bull profiled guide rail grinding machine is mainly used in the orbital plane of grinding machine lathe bed.
Background technology
The long rails face has a plurality ofly on the bed piece, comprises the lower platen face of two mountain faces, two planes and both sides, to the grinding of this lathe bed, all is to utilize numerical control slideway grinder in gantry respectively each face to be carried out grinding at present.Existing slideway grinder comprises lathe bed, the workbench that can vertically move along lathe bed is installed above lathe bed, workbench connects actuating unit, can vertically move on lathe bed at the driving lower table of control device and actuating unit, and the workpiece that is fixed on the workbench moves thereupon.There is column both sides at lathe bed, are connected with crossbeam above two columns, and bistrique moving up and down is housed on the crossbeam, workbench drive that workpiece movement moves up and down with bistrique and bistrique on the rotation of abrasive grinding wheel match and can carry out grinding the bed ways face.The grinding machine of this structure causes grinding speed slow owing to be single guide pass grinding, and error is big between each guide pass, and the precision of workpiece to be machined is not high.
Summary of the invention
The purpose of this invention is to provide that a kind of each guide pass can carry out grinding simultaneously, grinding speed is fast, the planer type numerical control bull profiled guide rail grinding machine that workpiece accuracy is high overcomes the deficiencies in the prior art.
Planer type numerical control bull profiled guide rail grinding machine of the present invention, comprise lathe bed, the workbench that vertically movably is connected with actuating unit with respect to lathe bed is installed above lathe bed, side at lathe bed has right column, opposite side has left column, above right column and left column, be connected with crossbeam, line slideway by the above-below direction setting on crossbeam is equipped with slide plate, huge guide rail by horizontal direction on slide plate is equipped with upper right grinding head body and upper left grinding head body, abrasive grinding wheel on upper right grinding head body and the upper left grinding head body all inwardly is oppositely arranged the formation symmetrical structure, the connecting plate connection is arranged between upper right grinding head body and the upper left grinding head body and connect driving mechanism, this driving mechanism is installed in an end of slide plate; All by cross slid platform down bistrique is installed on right column and left column, the abrasive grinding wheel on two following bistriques all inwardly is oppositely arranged the formation symmetrical structure.
Planer type numerical control bull profiled guide rail grinding machine of the present invention compared with prior art, have the advantage that each guide pass can carry out grinding simultaneously on the lathe bed, the grinding speed of bed ways face is fast, has improved operating efficiency, reduced processing cost, the positional precision between each guide pass is increased.
Description of drawings
Fig. 1 is that the master of the specific embodiment of the invention looks schematic diagram;
Fig. 2 is lathe bed shown in Figure 1 and the column schematic top plan view that is positioned at the lathe bed both sides;
Fig. 3 is that enlarged diagram is looked on a left side shown in Figure 1.
The specific embodiment
As shown in Figure 1, 2, 3: 1 is lathe bed, workbench 4 is installed on lathe bed 1, workbench 4 can vertically move with respect to lathe bed 1, workbench 4 connects actuating unit, actuating unit connects numerical control device, numerical control device and actuating unit can drive workbench 4 and vertically move along lathe bed, thereby the workpiece (processed lathe bed) that drives on the workbench 4 moves.Side at lathe bed is set with right column 2, and opposite side is set with left column 3, is connected with crossbeam 8 in the upper fixed of right column 2 and left column 3, forms the gantry type frame structure.
16 is line slideway, and totally four groups, 5 is slide plate, and slide plate 5 is installed on the crossbeam 8 by line slideway 16, and each line slideway is for vertically being provided with up and down.The centre position is installed with Worm-gear type lift drive mechanism 14 above crossbeam 8, in the middle part of slide plate 5 lifting screw 15 is installed, output screw mandrel and screw 5 on the lift drive mechanism 14 match, and lift drive mechanism 14 can drive slide plate 5 and move up and down with respect to crossbeam 8.
Horizontal direction is processed with huge guide rail on slide plate 5, by this huge guide rail upper right grinding head body 7 that is positioned at the right side and the upper left grinding head body 17 that is positioned at the left side are installed, upper right emery wheel 11 on the upper right grinding head body 7 and the upper left emery wheel 18 on the upper left grinding head body 17 all are oppositely arranged to the inside, form symmetrical structure.Between upper right grinding head body 7 and upper left grinding head body 17, be fixedly connected with connecting plate, two grinding head body can be moved with respect to slide plate 5 horizontal directions along huge guide rail simultaneously.12 for being installed in the last grinding wheel head driving mechanism that is made of motor reducer of slide plate 5 terminations, and the output horizontal screw lead 13 of this driving mechanism matches with screw on being installed in upper right grinding head body 7, can drive above-mentioned each grinding head body by horizontal screw lead 13 and move.
6 is the right cross slid platform of selecting for use, and 10 is the bottom right bistrique, and bottom right bistrique 10 is installed on the right column 2 by right cross slid platform 6; 20 is the left cross slid platform of selecting for use, and 19 is the lower-left bistrique, and lower-left bistrique 19 is installed on the left column 3 by left cross slid platform 20; Emery wheel 21 on the bottom right bistrique 10 and the emery wheel 22 on the lower-left bistrique 19 all are oppositely arranged to the inside, form symmetrical structure.
9 for being ground the workpiece (bed piece) of processing, there are a plurality of guide pass workpiece 9 tops, there is the lower platen face both sides, wherein each guide pass of top is by upper right emery wheel 11,18 grindings of upper left emery wheel, the lower platen face of both sides is by emery wheel 22 grindings on emery wheel on the bottom right bistrique 10 21 and the lower-left bistrique 19, and above-mentioned each grinding action can be carried out simultaneously.
Described each grinding wheel head structure is a prior art, no longer auspicious stating.
