Description
Technical field
The present invention relates to a kind of mechanism that is applied to main shaft lifting in the numerical control drilling-milling bed apparatus, be specially a kind of lifting structure of numerical control drilling-milling bed.
Background technology
In the technology that oneself has, the mechanism of the main shaft lifting of using in the numerical control device, its mechanism are made up of main shaft, spindle drum and hydraulic cylinder.Reach the flexible purpose of main shaft by stretching of hydraulic cylinder, thus the height of the processing work of satisfying the demand.But because the shortcoming of this hydraulic mechanism is to be easy to generate leakage, contaminated environment; Because of having leakage and elasticity to change greatly, be difficult for causing accurate transmission; Entrained air in the system, can cause climb, noise and vibrations; For having relatively high expectations of environment temperature; Fault diagnosis and the eliminating technology of having relatively high expectations, these all are not suitable for enterprise's production requirement.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of simple in structure, transmission efficiency is high, positioning accuracy is high, maintenance cost is low and the lifting structure that conforms the numerical control drilling-milling bed wide.
According to technical scheme provided by the invention, the lifting structure of described numerical control drilling-milling bed, comprise spindle drum, nut seat and move seat, on mobile seat, be fixed with nut seat, on nut seat, be installed with the lifting screw, on spindle drum, be installed with the servomotor mount pad, on the servomotor mount pad, servomotor be installed, on the output shaft of servomotor, driving pulley is installed; Sidewall at spindle drum is installed with two guiding line slideways that be arranged in parallel, on the guiding line slideway, slidely connect guide runner, described guide runner is fixedly mounted on and moves on the seat, the sidewall of the spindle drum between two guiding line slideways is installed with top chock and step, on top chock and step, be rotatablely equipped with the lifting ball screw, be installed with passive belt wheel in the upper end of lifting ball screw, on passive belt wheel and driving pulley, be provided with synchronous band, on the lifting ball screw between top chock and the step, be bolted with described lifting screw.
Between nut seat and mobile seat positioning key is installed, the length direction of described positioning key is identical with the length direction of lifting ball screw.
Between nut seat and mobile seat the adjustment pad is installed, the length direction of described adjustment pad is vertical with the length direction of lifting ball screw.
Structure structure of the present invention is simple, and transmission efficiency height, positioning accuracy height, maintenance cost is low and it is wide to conform.Because adopt line slideway as guiding parts, the difference of dynamic and static frictional force is very little, servo-actuated is fine, and time interval of hysteresis that can guarantee to drive signal and mechanical action is extremely short, the response speed and the sensitivity that help improving numerical control speed; Driving power descends significantly, only is equivalent to 1/10th of standard machinery; Can realize high position precision and repetitive positioning accuracy.

Fig. 1 is a front view of the present invention.
Fig. 2 is a vertical view of the present invention.
The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in the figure, the present invention mainly by move seat 1, step 2, lifting ball screw 3, positioning key 4, screw 5, adjust pad 6, nut seat 7, top chock 8, round nut 9, passive belt wheel 10, be with 11 synchronously, parts such as driving pulley 12, servomotor mount pad 13, servomotor 14, spindle drum 15, guiding line slideway 16, guide runner 17 and lifting screw 18 constitute.
The lifting structure of numerical control drilling-milling bed of the present invention, comprise spindle drum 15, nut seat 7 and move seat 1, on mobile seat 1, be fixed with nut seat 7 by screw 5, on nut seat 7, be installed with lifting screw 18, on spindle drum 15, be installed with servomotor mount pad 13, servomotor 14 is installed on servomotor mount pad 13, driving pulley 12 is installed on the output shaft of servomotor 14; Sidewall at spindle drum 15 is installed with two guiding line slideways 16 that be arranged in parallel, on guiding line slideway 16, slidely connect guide runner 17, described guide runner 17 is fixedly mounted on and moves on the seat 1, the sidewall of the spindle drum 15 between two guiding line slideways 16 is installed with top chock 8 and step 2, on top chock 8 and step 2, be rotatablely equipped with lifting ball screw 3, be installed with passive belt wheel 10 in the upper end of lifting ball screw 3, on passive belt wheel 10 and driving pulley 12, be provided with and be with 11 synchronously, on the lifting ball screw 3 between top chock 8 and the step 2, be bolted with described lifting screw 18.
Between nut seat 7 and mobile seat 1 positioning key 4 is installed, the length direction of described positioning key 4 is vertical with the length direction of lifting ball screw 3.
Be equipped with between nut seat 7 and mobile seat 1 and adjust pad 6, the length direction of described adjustment pad 6 is identical with the length direction of lifting ball screw 3.
