Abstract
The utility model discloses a servo hydraulic mechanism for floor boring upright inclination adjustment. The servo hydraulic mechanism utilizes a front hydrostatic guide rail connected with a front pipeline and a rear hydrostatic guide rail connected with a rear pipeline to support an upright, the front hydrostatic guide rail and the rear hydrostatic guide rail are arranged on a machine tool body, the front pipeline is connected with a servo proportional reducing valve, a headstock can move up and down along the upright, and a tool is mounted in the headstock. When a workpiece is machined by the tool, the upright tends to incline backward, at the moment, the opening of the servo proportional reducing valve is controlled to become small, so that the thickness of the oil film on the front hydrostatic guide rail is reduced, and as a result, the upright tends to incline forward to balance the backward inclination of the upright, which is caused by the stressed tool. Compared with the conventional mechanism, the servo hydraulic mechanism has the advantages that: the adjustment data of the servo hydraulic mechanism can be easily controlled, and the inclination angle of the upright can be dynamically controlled in real time.
Description
Technical field
The utility model relates to and lands the servo-hydraulic device of boring column tilt adjustments
Background technology
In the boring of the landing processing, because cutter is stressed, make column that the trend of hypsokinesis be arranged, such result just makes the preceding point of cutter uprise relatively, destroy machining accuracy, main spindle box is more near the top of column, it is obvious more that this trend can become, in the existing machine tool, the main spindle box with certain angle of inclination is set, remedies the machining accuracy that column tilts to cause and wander away, like this because the angle of inclination difference of main spindle box column when the different parts of column, causing can not the fine data that must grasp angle adjustment, can not carry out dynamically adjusting in real time in the column angle of inclination, and machining accuracy still can be wandered away
Summary of the invention
The purpose of this utility model provides a kind of servo-hydraulic device of can be directly adjusting at the angle of inclination of column that lands boring column tilt adjustments, and it can separate the problem that must not well grasp the data of angle adjustment.
For achieving the above object, the utility model provides a kind of servo-hydraulic device that lands boring column tilt adjustments, comprise column, be arranged on the bed piece of described column bottom, both sides are provided with before and after described bed piece top preceding hydrostatic slideway and back hydrostatic slideway along the left and right directions extension, the bottom have groove and hydraulic pressure installation site and by described groove cover be pressed in described before the planker of the described column of supporting on hydrostatic slideway and the back hydrostatic slideway, be used for fuel tank to this device fuel feeding, what be communicated with described fuel tank is used for the main pipe rail that the transfer tank fuel feeding arrives described planker hydraulic pressure installation site, one end is communicated with the other end and is connected to pipeline on the described rear rail with described main pipe rail, one end is communicated with the other end and is connected to pipeline on the described fromer rail with described main pipe rail, it is characterized in that: be connected with on the pipeline before described can external control panel the servo ratio pressure-reducing valve.
Because technique scheme utilization, the utility model compared with prior art has following advantage and effect: device has the preceding hydrostatic slideway and back hydrostatic slideway that is arranged on the bed piece, the preceding pipeline of hydrostatic slideway fuel feeding forward, the back pipeline of hydrostatic slideway fuel feeding backward, before being connected on the pipeline can external electric control gear the servo ratio pressure-reducing valve, adopt after this structure, device can be adjusted fuel feeding to preceding hydrostatic slideway according to the angle of inclination of column, and then realize the adjustment at column angle of inclination by the oil film thickness on the hydrostatic slideway before adjusting, the data simple, intuitive of angle adjustment has effectively improved machining accuracy.
Description of drawings
Accompanying drawing 1 is looked schematic diagram for master of the present utility model.
The specific embodiment
Further set forth structure of the present utility model below in conjunction with accompanying drawing.
Referring to shown in Figure 1, both sides are provided with the preceding hydrostatic slideway 6 and back hydrostatic slideway 3 that extends along left and right directions before and after the top of bed piece 2, the planker 5 that the bottom has groove and a hydraulic pressure installation site by bottom groove cover be pressed in before on hydrostatic slideway 6 and the back hydrostatic slideway 3, by planker 5 supporting upright posts 1, can make even must being born of pressure of column 1 on the one hand by planker 5, planker 5 and preceding hydrostatic slideway 6 have been alleviated on the other hand, the abrasion of back hydrostatic slideway 3, the fuel feeding of fuel tank 12 after the output of total oil circuit 11, midway by be split up on total oil circuit 11 be connected to before 6 preceding pipeline 10 and the back pipeline 8 that is connected on the hydrostatic slideway 3 of back on the hydrostatic slideway.
In Fig. 1, preceding pipeline 10 and back pipeline 8 difference pressure oil output are at preceding hydrostatic slideway 6, form oil film on the back hydrostatic slideway 3, on preceding pipeline 10, be provided with can external control panel servo ratio pressure-reducing valve 9, first being processed, at first set the angle of inclination of column 1 and the data that servo ratio pressure-reducing valve 9 is adjusted the pressure oil flow, in process, cutter is stressed to make column 1 hypsokinesis, at this moment, according to the data that configure in advance, adjust the pressure oil flow by servo ratio pressure-reducing valve 9 and realize that the oil pressure of preceding hydrostatic slideway 6 reduces, the thickness attenuation of the oil film 7 before the oil pressure of preceding hydrostatic slideway 6 reduces to make on the hydrostatic slideway 6, column 1 comes column 1 angle of the stressed generation of balance cutter to change with regard to having produced the trend that leans forward like this, has remedied machining accuracy and has wandered away, and reaches the requirement of machining accuracy
