Abstract

A multi-functional combinable numerical control machine tool is provided, which comprises a modularized base, a slide platform, a workbench and a column. A gear change module can be positioned inside the multi-functional headstock; a module with transmission function can be positioned outside the headstock; and a suspender cutter broaching module and a pneumatic cutter releasing module are respectively positioned in the principal axis. The combination of multi-functional modules assure a series of outstanding technical performances such as numerical control multiple axis coordinated action, transmission speed regulation by frequency variation, pneumatic fast cutter change and full-cover protection of machine tool. In addition, the utility model is able to, according to the demands of user, add or remove the combined functional parts to form longitudinal and horizontal numerical control machine tools of various pricing and different functions, so that the users are able to acquire machine tools with the most advanced functions at moderate cost.

Description

The Digit Control Machine Tool that function is capable of being combined

Affiliated technical field

The utility model relates to a kind of function Digit Control Machine Tool capable of being combined.

Background technology

Existing Digit Control Machine Tool function dullness; Machining center lathe price is expensive, and moment of torsion is little when the slow-speed of revolution.

Summary of the invention

The utility model provides a kind of modularization, function Digit Control Machine Tool capable of being combined.

The technical scheme that the utility model adopted is: this lathe comprises modular base, cross table, column, multi-functional main spindle box; In the main spindle box gear transmission module can be installed, but the outer mounting strap transmission module of main spindle box; Suspension rod broaching tool module or pneumatic loose broaching tool module can be installed in the main shaft.The different combination of module can form the different Digit Control Machine Tool of performance.

Gear drive module moment of torsion when low speed is big; Variable-frequency motor can be realized high speed transmission and stepless speed regulation by the band transmission module; But pneumatic loose broaching tool module rapid changing knife; Suspension rod broaching tool module is simple and reliable; The modularization base can be installed full protection and local protected enclosure respectively; Modularization column and workbench are installed multiple drive motors respectively.

The beneficial effects of the utility model are that the lathe that comprehensively makes of advanced function module has the following premium properties of machining center lathe: multi-shaft interlocked, frequency control, pneumatic tool changing, full cover protection; The choice of advanced function module can form the Digit Control Machine Tool of multiple different price and difference in functionality.Make the user obtain to possess the lathe of necessary advanced function with the investment that economizes most.

Description of drawings:

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is total figure of the present utility model.This lathe comprises modular base 1, cross table 2, column 3, multi-functional main spindle box 4, protected enclosure 5.Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 are the main spindle box structure charts that the utility model proposes.Gear transmission module 6 (Fig. 2, Fig. 3) can be installed in the main spindle box, but the outer mounting strap transmission module 7 (Fig. 4, Fig. 5) of main spindle box, gear transmission module 6 is installed in the main spindle box, the outer mounting strap transmission module 7 (Fig. 6) of case can be installed pneumatic loose broaching tool module 8 (Fig. 2, Fig. 4, Fig. 6) or suspension rod broaching tool module 9 (Fig. 3, Fig. 5) in the main shaft.

The specific embodiment

The utility model can form the main spindle box of following five kinds of difference in functionalitys.Fig. 2 is gear drive, pneumatic loose broaching tool main spindle box structure chart, and moment of torsion was big when performance characteristics was low speed, can realize rapid changing knife.Fig. 3 is gear drive, suspension rod broaching tool main spindle box structure chart, and moment of torsion was big when performance characteristics was low speed, tool-broaching mechanism simple, reliable operation.Fig. 4 is band transmission, pneumatic loose broaching tool main spindle box structure chart, and performance characteristics is to realize high rotating speed, stepless speed regulation and rapid changing knife.The transmission of Fig. 5 band, suspension rod broaching tool main spindle box structure chart, performance characteristics are high rotating speed, stepless speed regulation, simple, the reliable operation of tool-broaching mechanism.Fig. 6 is that band transmission, gear drive binding ability characteristics are high rotating speed, big retarding ratio, and moment of torsion is big.

Fig. 3, suspension rod broaching tool module shown in Figure 5 are made up of main shaft 10, handle of a knife 11, suspension rod 92, pad 91, screw or unclamp the suspension rod screw thread and can strain or unclamp handle of a knife 11.

Fig. 2, pneumatic loose broaching tool module shown in Figure 4 are made up of main shaft 10, handle of a knife 11, blind rivet 88, cylinder 81, fixed head 82, adjusting bolt 83, loose broaching tool bar 85, tension executive item 87, spring 86, guideway 84.The operating process of pneumatic tool changing is finished by loose cutter, two actions of broaching tool, tool change time 3 seconds, and the course of work is as follows:

(1) loose cutter: press knob, cylinder 81 piston rods move down fast impact loose broaching tool bar 85, knife bar move down fast impact handle of a knife 11, tension executive item steel ball 87 footpaths outwards move on to and unload the cutter groove, handle of a knife is released to be unloaded.

(2) broaching tool: load onto handle of a knife 11 on main shaft 10, press button, cylinder 81 piston rods upwards return fast, and under the elastic force effect of spring 86, loose broaching tool bar 85 moves on fast, inwardly contract in steel ball 87 footpaths, and pulling handle of a knife 11 moves in taper hole on fast and strains.

Fig. 2, gear drive module shown in Figure 3 are made up of 2 grades of gear reductions, and double-speed motor drives, the range of speeds 265～1815r/min.Fig. 3, band transmission module shown in Figure 4 are with reducing gear to form by 1 grade synchronously, and variable-frequency motor drives, speed reducing ratio 1: 1, the range of speeds 300～6000r/min; 1: 2 range of speeds 150～3000r/min of speed reducing ratio.Main motor on the main spindle box can be double-speed motor, variable-frequency motor; Can distinguish the gear graduation transmission module in the junction box, the band transmission module drive shaft running that junction box is outer; Can obtain low-speed big and high speed, stepless speed regulation respectively.
