A hydraulic mechanism for driving the workbench to move along the direction limited by the workbench base is arranged between the workbench base and the workbench. The improved numerically controlled miller has the advantages that the workbench on the miller is driven hydraulically, compared with a common machine tool, the improved numerically controlled miller is high in speed, high in efficiency, simple in operation and lower in maintenance, compared with an existing numerically controlled machine tool, the improved numerically controlled miller is equivalent to the existing numerically controlled machine tool in terms of speed, and is far lower in cost and even lower in maintenance cost.

Description

A kind of improved CNC milling machine

Technical field

The utility model belongs to the CNC milling machine field, is specifically related to a kind of improved CNC milling machine.

Background technology

The feeding mode of existing plain-milling machine is: adopt feeding motor driven gear gearbox, and then by the gear driven screw mandrel, and by screw mandrel drive movable workbench.Such mechanism has determined that plain-milling machine speed when idle stroke is very slow, and can't realize control automatically in process, has directly caused the efficient of plain-milling machine comparatively low.

The feeding mode of the CNC milling machine that development in recent years is very fast is: adopt servomotor directly to drive screw mandrel, drive movable workbench by screw mandrel then.Though this mechanism makes that the speed of CNC milling machine when idle stroke is very fast, need obtain the support of digital control system during owing to the servomotor operation, thereby increase the production of lathe and made use cost.

Summary of the invention

The purpose of this utility model provides a kind of improved CNC milling machine, its simple structure, and operating rate is fast and efficient is high.

For achieving the above object, the utility model has adopted following technical scheme: a kind of improved CNC milling machine, comprise the workbench that is arranged on the table base, be provided with between described table base and the workbench and drive the hydraulic mechanism that direction that workbench limits along table base moves.

The beneficial effects of the utility model are: the workbench on the milling machine adopts hydraulic drive, compares with machine tool, and speed is fast, the efficient height, and simple to operate, maintenance cost is lower than machine tool; Compare with existing Digit Control Machine Tool, speed is suitable with existing Digit Control Machine Tool, and cost is then cheap more than existing Digit Control Machine Tool, and maintenance cost is just lower.

Description of drawings

Fig. 1 is the structural representation of the CNC milling machine in the utility model;

Fig. 2 is the left view of Fig. 1.

The specific embodiment

Horizontal hydraulic milling machine as shown in Figure 1, 2, it comprises base 1, lifting platform 2, table base 3, main shaft 4, cutter 5, knife bar 6, spindle carrier 7, overarm 8, lathe bed 9, PLC programmable logic controller (PLC) 10, hydraulic jack 11, workbench 12, workbench carriage 13, piston unt 14.

Improved CNC milling machine in the utility model comprises the workbench 12 that is arranged on the table base 3, is provided with between described table base 3 and the workbench 12 to drive the hydraulic mechanism that direction that workbench 12 limits along table base 3 moves.

Described hydraulic mechanism comprises hydraulic jack 11 and the piston 15 that formation each other is slidingly matched, hydraulic jack 11 is fixed on one of them among the two of table base 3 and workbench 12, and 15 in piston is fixed on table base 3 and workbench 12 another one among the two.

Further, as shown in Figure 1, 2, described hydraulic jack 11 is fixed on the table base 3, the end of workbench 12 protruding formation workbench carriage 13, and the downside of workbench carriage 13 is installed with nut 14, and described nut 14 is affixed with the head of piston 15.

Also be that hydraulic jack 11 is horizontal installation, hydraulic jack 11 is fixed on the table base 3 by screw, and the piston 15 of hydraulic jack 11 is fixed on the workbench carriage 13 by piston unt 14.

Further again, also be provided with programmable logic controller (PLC) 10 on the milling machine, described programmable logic controller (PLC) 10 is electrically connected with hydraulic valve and magnetic valve in the hydraulic mechanism.

The English full name Programmable of PLC Logic Controller, Chinese full name is a programmable logic controller (PLC), its definition is: a kind of electronic system of digital operation operation aims in industrial environment and uses and design.It adopts a class programmable memory, be used for its internally stored program, actuating logic computing, sequential control, regularly, user oriented instructions such as counting and arithmetical operation, and control various types of machineries or production process by numeral or analog I/O.

PLC programmable logic controller (PLC) 10 in the utility model is installed in the electric box of milling machine, and it controls the rotation of main shaft 4 by outside executive component, and control workbench 12 motion at a slow speed soon.

Be described further below in conjunction with Fig. 1,2 pairs of runnings of the present utility model:

Overarm 8 is fixed on the top of lathe bed 9, and can move along the upper rail of lathe bed 9, and lathe bed 9 is fixed on the base 1 of milling machine.

Spindle carrier 7 is fixed in the overarm 8, and the effect of spindle carrier 7 is ends that hold up main shaft 4, and main shaft 4 is fixed on the first half of lathe bed 9, and knife bar 6 is fixed between spindle carrier 7 and the main shaft 4, and cutter 5 is fixed on the knife bar 6.

Lifting platform 2 moves up and down along the guide rail of lathe bed 9 sides, and table base 3 moves forward and backward along the horizontal guide rail on the lifting platform 2, sets table base 3 this moment and moves to forward to the direction of lathe bed 9, and table base 3 moves to backward to the direction away from lathe bed 9.

The side-to-side movement of workbench 12 leans on the promotion of hydraulic jack 11, and hydraulic jack 11 is fixed on the table base 3, and the piston 15 of hydraulic jack 11 is fixed on the workbench carriage 13 by nut 14, just drives workbench 12 side-to-side movements when piston 15 motions.
