Abstract
The utility model belongs to metal cutting machine tools, and particularly relates to a crossbeam lifting positioning device for a heavy vertical numerical-control machine tool, which comprises a crossbeam and two electric lead screw lifting mechanisms. The crossbeam lifting positioning device is characterized in that two position feedback elements are symmetrically assembled on outer sides of the two electric lead screw lifting mechanisms, and output signals of each position feedback element are communicated and connected with a numerical-control system of the machine tool by signal circuits. The crossbeam lifting positioning device not only is reasonable in design and accurate and scientific in positioning, is simple and practical, but also has the advantages that the crossbeam lifting positioning device is convenient in installation and extremely convenient in use, the crossbeam can be accurately positioned at an optional position, cutting processing efficiency is improved, and the like.
Description
Technical field
The utility model belongs to Metal Cutting Machine Tool, particularly a kind of crossbeam lifting-positioning device of heavy vertical type numerically controlled machine.
Background technology
At present; When the big workpiece of cut; Extensively adopt heavy vertical type numerically controlled machine to carry out cut; Its structure comprises the cross-rail-elevating mechanism and the machine tool numerical control system of support, column, workbench, screw type, symmetry installing two columns at the support two ends, installation platform on the base surface between two columns; Two electronic screw-threaded shaft elevator structures that its crossbeam is installed through symmetry are connected and carry out synchronous upper and lower moving on the column, and its cutting tool is to be connected on the crossbeam through feed mechanism to move; Its each electronic screw-threaded shaft elevator structure be by motor, reduction box with transmission of power to lead screw pair, thereby drive crossbeam is positioned work piece along upper and lower its cutting tool of mobile drive of column Working position; And crossbeam the location on the column be through operator's visual fix after, realize by electric switch by hand.The shortcoming and defect part of the crossbeam positioner that it is above-mentioned is: not only inaccuracy but also non-science, and can not realize the accurate location of crossbeam optional position.
Summary of the invention
The utility model is intended to the shortcoming and defect part that in above-mentioned technology, exists; And provide not only reasonable in design; Simple and practical, not only located accurately but also science, and had and be convenient to install; Realize the accurate location of crossbeam optional position, improve cut efficient and use a kind of crossbeam lifting-positioning device of heavy vertical type numerically controlled machine very easily.
The purpose of the utility model is to adopt following technical scheme to realize: the crossbeam lifting-positioning device of described heavy vertical type numerically controlled machine; Comprise crossbeam, two electronic screw-threaded shaft elevator structures; It is characterized in that: two position feedback elements of symmetry installing in the outside of two electronic screw-threaded shaft elevator structures, the output signal of described each position feedback element all is communicated with machine tool numerical control system through signal line and joins.
Described each electronic screw-threaded shaft elevator structure is made up of servomotor, reduction box and ball screw assembly.
Described position feedback element adopts grating chi formula, ball bar formula or adopts magnetic-grid-type.
The utility model is in order to realize the pinpoint purpose in crossbeam optional position; Cross-rail-elevating mechanism adopts two covers to connect the high precision ball leading screw by servomotor through reducing gear; And be equipped with the position feedback element and make up with machine tool numerical control system and realize the control of crossbeam up-down full cut-off ring, thereby accurately locate realization crossbeam optional position.When crossbeam went up and down, servomotor arrived ball screw assembly, through reduction box with transmission of power, moved up and down to desired location along the column guide rail thereby drive crossbeam.The signal of position feedback element output simultaneously makes machine tool numerical control system monitor the synchronisms of two electronic screw-threaded shaft elevator structure motions of drive crossbeam motion automatically, and crossbeam can parallelly move to the optional position in the crossbeam workspace and accurately locate like this.
The comprehensive above technical scheme of being taked, the purpose of realization the utility model.
Compared with prior art, the utility model is not only reasonable in design, and is simple and practical, not only located accurately but also science, and had and be convenient to install, and realizes the accurate location of crossbeam optional position, improves cut efficient and uses characteristics such as very convenient.
