Abstract

The invention relates to a large-scale machine tool drive device, and in particular relates to a large-scale reflex kinematic machine tool drive device. The large-scale reflex kinematics machine tool drive device comprises a machine tool frame and a machine tool body, and is characterized in that a force point fixed pulley fixed on one end of the machine tool frame, machine tool body fixed pulleys uniformly distributed on the machine tool body, a roller and a hoisting drum fixed on one end of the machine tool, and a gear shifting mechanism and a speed control motor sequentially arranged on the hoisting drum, wherein wire ropes are wound on the force point fixed pulley, the machine tool body fixed pulleys and the hoisting drum. The large-scale reflex kinematic machine tool drive device has a unique structure, low cost and a good environmental-protection effect, and can manufacture large-scale manufacture machine tools with arbitrary sizes to suit the integral processing of large-scale workpieces and improve the product manufacture accuracy.

Description

The drive unit of large-scale reciprocating type motion lathe

Technical field

The present invention relates to a kind of drive unit of heavy duty machine tools, especially relate to the drive unit of large-scale reciprocating type motion lathe.

Background technology

The planer-type milling machine of producing both at home and abroad and gantry wound bed all adopts fluid pressure drive device and spiro driving device at present, these two kinds of drive systems surpass more than the 6000mm in lathe length, almost just can not grow again, so the above lathe of 6000mm is exactly a blank, but the above workpiece of 6000mm is a lot, in order to solve whole processing problems, the processing machine tool above 6000mm length just must be arranged above the workpiece more than the 6000mm length.Along with industrialized development, large-scale and oversized engineering is more and more, and large-scale workpiece is also more and more, and required precision is also more and more higher, so corresponding processing machine tool must be arranged.But existing hydraulic-driven and screw drive system can't solve this difficult problem, also are the main bottlenecks of restriction heavy duty machine tools development.

Summary of the invention

The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of structure uniqueness, cost is low, environment protecting good, can produce the large-scale manufacturing machine tool, the integral body processing to adapt to large-scale workpiece, the drive unit that improves the large-scale reciprocating type motion lathe of the product accuracy of manufacture of arbitrary dimension.

The present invention realizes in the following way:

A kind of drive unit of large-scale reciprocating type motion lathe, it comprises lathe bedstead and lathe bed thereof, it is characterized in that: on an end of above-mentioned lathe bedstead, be fixed with the force fixed pulley, on bed piece, be evenly equipped with the lathe bed fixed pulley, be fixed with carrying roller and elevator drum at above-mentioned lathe bedstead one end, be furnished with gear and variable-speed motor on the elevator drum, all be wound with steel wire rope on above-mentioned force fixed pulley, lathe bed fixed pulley and the elevator drum;

Described force pulley is furnished with two in the bilateral symmetry of an end of lathe bedstead, and the lathe bed fixed pulley is evenly equipped with four at the middle part of described bed piece.

The present invention has following effect:

1) structure uniqueness: the inventive system comprises lathe bedstead and lathe bed thereof, it is characterized in that: on an end of above-mentioned lathe bedstead, be fixed with the force fixed pulley, on bed piece, be evenly equipped with fixed pulley, be fixed with carrying roller and elevator drum at above-mentioned lathe bedstead one end, be furnished with gear and variable-speed motor on the elevator drum, all be wound with steel wire rope on above-mentioned force fixed pulley, bedstead fixed pulley and the elevator drum; This device is main by changing drive system power propulsion system just, substitute existing hydraulic system and screw rod propulsion system with novel winding plant, this novel drive system adopts the principle of hoist engine, carries out a kind of drive system that reciprocating type moves in conjunction with the fulcrum relation of each tractive force of lathe itself and device.

2) cost is low, environment protecting good: elevator drive system and fluid power system that the utility model provides, the screw drive system compares: cost is 1/10th of a hydraulic pressure, it is 1/15th of screw rod, and the power set consumption that provides of the utility model be like product 1/3rd less than, noise reduces the 20-25 decibel, hydraulic oil saves 100%, pollutes and reduces by 85%, about 1000 kilograms of conservation of raw material.

4) by changing the drive unit of present stage large-sized gantry machine, the manufacturing technology of heavy duty machine tools is simplified, utilize this technology can produce the large-scale manufacturing machine tool of arbitrary dimension, to adapt to the integral body processing of large-scale workpiece, improve the accuracy of manufacture of product, produce huge lathe for machine-tool industry drive system is provided.
