Description

Combined machine tool

The utility model relates to a kind of building-block machine that is used for metal cutting processing.

The lathe of factory's use at present mainly contains lathe, milling machine, drilling machine, grinding machine, planer etc., integrated mill or specialized factory generally easily are equipped with complete, most of individualities, township enterprise, collective or state-run small enterprise then are difficult to all be equipped with, in order to keep in repair some part of processing, they have to entrust others to process, and both waste time, spend processing charges again, in order to satisfy the needs of these small business, people have designed some building-block machine, and general requirement is:

1, simple in structure, function is reasonable.The machined workload of maintenance work, generally based on car, bore, mill, other processing work post as grind, insert, draw, shovel, boring etc. are minute quantities.So the function that building-block machine should possess should be based on turner, driller and miller, other work post is inferior.Function is reasonable, does not promptly pursue too much function and both can make machine tool structure simple, and annex is few, and is easy to manufacture, can satisfy the requirement of maintenance work again basically.

2, simple to operate, use method of operating similar as far as possible to existing all kinds of lathes.The processing work post situation more complicated in general of maintenance workpiece to the processing of the small workpiece of general structure, is not answered the too much annex of dismounting when conversion processing work post.

3, exchange generally as far as possible with the parts of the existing all kinds of machine tools in market, increase user's facility.

4, adopt a motor rather than a plurality of motor, to reduce the reliability of cost and increase work.

But the building-block machine that existing market is sold and documents and materials are put down in writing makes the structure more complicated in order to pursue multi-functional, annex is many, the processing and manufacturing difficulty is big, universal component interchangeability is poor, and operation is also inconvenient, and what have also will adopt a plurality of motors, cost is than higher, and in the middle of using, when conversion processing work post, also want the certain annex of dismounting, be difficult to adapt to the repairing workpiece of complex work.

The purpose of this utility model is to overcome above deficiency, provides a kind of simple in structure, a tractor serves several purposes, and function is reasonable, and practicality, economy conform with market demands, and be easy for operation, parts interchangeability versatility height, building-block machine applied widely.This building-block machine can carry out processing such as car, brill, vertical milling to general design of mini workpiece, when the conversion work post, except that mounting cutter, can very adapt to the maintenance workpiece of complex work, high efficiency without the dismounting annex, in addition, also can bore at any angle, mill and boring work.

Of the present utility modelly mainly be contemplated that: 1, only be used as power with a motor; 2, transform headstock and also slew gear is set up, set up universal radial drill milling mechanism on the slew gear again; 3, the cutter spindle installing hole that crouches is set on lathe spindle top; 4, the centre frame that mills for sleeping in is set on tail stock; 5, brill is set and mills workbench on the lathe slip crate, workbench is provided with standing vice.

The utility model will be further described below in conjunction with accompanying drawing:
