Description

The shake knife system of the continuous flat jet cutting machine knife rest of numerical control abnormity bubble

Affiliated technical field:

A kind of shake knife system that relates to the continuous flat jet cutting machine knife rest of numerical control abnormity bubble.This device is to make zigzag band cutter high speed vibration back and forth, thereby reaches the continuous purpose of cutting bubble.

Background technology:

Before present patent application, the shake knife system that a kind of eccentric wheel type has been arranged, this device is to utilize the driven by motor that is placed on the knife rest antetheca to be positioned at a disk rotation of knife rest, is connected by the swing arm of connecting rod with close steel wire rope place with the pin of a distance of disc centre biasing.The left end kink of this swing arm is on a steady pin, and right-hand member is fixed the steel wire rope that drags band cutter generation chatter.When motor turned round, disk fortune circled, and connecting rod drags swing arm and swings up and down once, on the pulling steel wire rope next time.The amplitude of band cutter is exactly the eccentric throw of connecting rod on disk.Steel wire rope passes to the two ends of band cutter to motion by four guide wheels that are positioned on four angles of knife rest, thereby finishes chatter.

The benefit of this device is simple in structure, and cost is low.But the shortcoming that also has some can not be ignored, that is:

1, noise is big, influences environment.

2, an end kink of swing arm is on a steady pin, thereby be fixed on cam pin on the disk when driving swing arm and swing up and down by connecting rod, fixedly the other end of steel wire rope is to be that circular motion is walked at the center with the steady pin, causes the steel wire rope shake of tightening and steel wire rope is worked under one one tight state.

3, owing to limited space system in the knife rest, common electric machine can only be suspended on the outside of knife rest, influences attractive in appearance.

4, convert the rectilinear motion of band cutter by electric energy to, need increase wearing and tearing, power consumption through the eccentric mechanical device of a cover.

Summary of the invention:

In order to solve the deficiency of said mechanism, the utility model provides following technical scheme to be: the two ends of linear electric motors 1 mover of shake knife system link to each other with the end-fitting of steel wire rope 3-01,3-02 respectively, steel wire rope 3-01,3-02 walk around guide wheel 2-02,2-01,2-03 and 2-04 respectively and link to each other with ball spline shaft 5-01, the 5-02 outer end of rotary ball spline, rotary ball spline has rotor head 4-01,4-02 respectively, and the two ends of toothed belt cutter 6 are connected with the inner of ball spline shaft 5-01,5-02 respectively.Linear electric motors 1, steel wire rope 3-01,3-02, guide wheel 2-02,2-01,2-03 and 2-04, ball spline shaft 5-01,5-02, rotor head 4-01, the 4-02 of ball spline and band cutter 6 are formed an obturator.In addition, water droplet shape joint is drawn at the two ends of steel wire rope 3-01,3-02 respectively, and with clip fix, banding, the end connector of steel wire rope 3-01,3-02 links to each other with connecting plate on the linear electric motors 1 respectively, steel wire rope 3-01,3-02 two ends connect all with water droplet shape joint and usefulness pressing plate and screw fastening.

The beneficial effects of the utility model are: 1, the noise of linear electric motors is low and volume is little, and noise is below 75 decibels; 2, do not have additional mechanical device and motion, thereby reduce wear and power consumption; 3, linear electric motors have high acceleration-deceleration, instantaneous reverse and instantaneous acceleration function, and the installation of electromechanical integrated product is time saving and energy saving.
