Abstract

The utility model relates to a numerical control machining center and belongs to the technical field of a numerical control machine structure. The numerical control machining center comprises a worktable for clamping a workpiece. The worktable is provided with a transverse upright post. The transverse upright post is provided with a cross sliding seat. The upper end of the cross sliding seat is connected with a Y-axis screw rod, while the lower end thereof is connected with an X-axis screw rod. The upper part of the Y-axis screw rod is provided with a longitudinal upright post which can move up and down along a vertical sliding ram. The longitudinal upright post is connected with a Z-axis screw rod. The lower end of the vertical ram is connected with a spindle with a cutter. In the machining process, the workpiece is statically clamped on the worktable, and thus, compared with the existing machine tool, the movable post numerical control machining center of the utility model has the advantages that 1, sweeps, cooling liquid and the like which are generated by cutting cannot be contacted with a movement part of the machine tool so as to prolong the service life of the machine tool; 2, the movable post numerical control machining center can realize clamping of the workpieces in regions and realize uninterrupted machining; and 3, compared with the conventional machine tool with the same machining range, the machine tool of the utility model can save castings by 30 to 40 percent, particularly the large-scale machine tool.

Description

The moving column type numerical control machining center

Technical field

The utility model relates to a kind of numerical control machining center, belongs to the structure of numerically controlled machine-tool technical field.

Background technology

At present, traditional CNC milling machine as shown in Figure 2, it is compared plain-milling machine and has machining accuracy height and advantage of high processing efficiency, but existing CNC milling machine also exists following problem simultaneously: because workpiece also will be along with the motion parts motion of lathe in process, so the scrap after causing cutting, cooling fluid etc. can be scattered on the lathe, not only cleaning is got up pretty troublesome, but also can shorten service life of lathe, and the weight of workpiece also can influence the precision of lathe, and the workpiece that finally causes processing can not reach higher required precision.

Summary of the invention

The purpose of this utility model is to solve the weak point that above-mentioned prior art exists, and provides a kind of and can increase the service life, realizes uninterruptedly processing, save material, moving column type numerical control machining center that precision is higher.

The moving column type numerical control machining center, special character is to comprise the workbench that is used for card engaging workpiece, workbench is provided with transverse upright, be connected with cross slide seat by the X-axis screw mandrel on the transverse upright, the upper end of cross slide seat is connected with the Y-axis screw mandrel, and the top of Y-axis screw mandrel is provided with vertical column, and vertically column one side is connected with Z axial filament bar, vertical ram moves up and down by Z axial filament bar, and vertical ram lower end connects the main shaft that has cutter.

Moving column type numerical control machining center of the present utility model, because adding the man-hour workpiece is static being installed on the workbench, so comparing existing lathe has the following advantages: 1, Qie Xiao scrap, cooling fluid etc. just can not contact the motion parts of lathe, thereby have prolonged the service life of lathe; 2, can realize that the workpiece subregion is installed, realize uninterruptedly processing; 3, the lathe of the same range of work can be saved the foundry goods of 30-40% than traditional machine tool, and heavy duty machine tools are more obvious; 4, the lathe positioning accuracy does not change because of processing work weight, thereby improves machine finish.

The specific embodiment

Following with reference to accompanying drawing, provide the specific embodiment of the present utility model, be used for formation of the present utility model is further specified.

Embodiment 1

The moving column type numerical control machining center of present embodiment is with reference to figure 1, comprise the workbench 1 that is used for card engaging workpiece, workbench 1 is provided with transverse upright 2, be connected with cross slide seat 4 by X-axis screw mandrel 3 on the transverse upright 2, the upper end of cross slide seat 4 is connected with Y-axis screw mandrel 5, and the top of Y-axis screw mandrel 5 is provided with vertical column 6, and vertically column 6 one sides are connected with Z axial filament bar 7, vertical ram 8 moves up and down by Z axial filament bar 7, and vertical ram 8 lower ends connect the main shaft 9 that has cutter.

Operation principle: be installed on the workbench 1 workpiece is static, X-axis screw mandrel 3 on the lathe, Y-axis screw mandrel 5 is installed on the transverse upright 2 at lathe rear portion, Z axial filament bar is on vertical column 6, motor drags cross slide seat 4 and moves on transverse upright 2, stroke range is from 500 millimeters to tens meters, motor above the cross slide seat 4 drags vertical column 6 and does lengthwise movement, stroke range from 500 millimeters to 1800 millimeter, vertical column 6 protrusive surfaces are equipped with vertical ram 8 and move up and down, stroke range is from 500 millimeters to 1000 millimeters, on the vertical ram 8 spindle motor is installed and power is passed to main shaft 9, cut thereby drive cutter through reducing gear.

The moving column type numerical control machining center of present embodiment, because adding the man-hour workpiece is static being installed on the workbench, so comparing existing lathe has the following advantages: 1, Qie Xiao scrap, cooling fluid etc. just can not contact the motion parts of lathe, thereby have prolonged the service life of lathe; 2, can realize that the workpiece subregion is installed, realize uninterruptedly processing; 3, the lathe of the same range of work can be saved the foundry goods of 30-40% than traditional machine tool, and heavy duty machine tools are more obvious; 4, the lathe positioning accuracy does not change because of processing work weight, thereby improves machine finish.
