Abstract
This patent discloses ultra-magnetic telescopic formula high-speed cutting roll adjusting mechanism, design feature is: knife bar end is connected with knife rest by straight pin, and knife rest is fixed with alternating electromagnet, and knife bar is fixed with magnet, super-magnetostrictive drive end is fixed on knife rest, and extension bar contacts with knife bar.The utility model is applied to roll adjusting mechanism super-magnetostrictive drive and electromagnet, substantially increase roll setting speed, under solving high-speed cutting condition (> 1000m/min), a difficult problem for desirable chip simulation cannot be obtained, this device is by Electromagnetic Control, operating personnel can operate outward whole roll setting process, without potential safety hazard at safe distance.
Description
Technical field
The utility model relates to turned part, specifically, relates to ultra-magnetic telescopic formula high-speed cutting roll adjusting mechanism.
Background technology
Various physical phenomenons in working angles, the wearing and tearing of heat in metal cutting, cutter, the quality of machined surface, the change of chip grain size etc. are all relevant with chip, and chip simulation is due to the startup of the distortion and shear band that remain the chip of cutting lay material flowing therethrough primary deformation zone and expansion process, has very important researching value.
Turning roll adjusting mechanism is the common tool obtaining chip simulation, in normal working angles, makes cutter depart from workpiece instantaneously by external force, can obtain the chip simulation be connected with workpiece.Along with the progress of scientific research, require more and more higher to cutting speed, in general, in high-speed cutting situation, roll setting speed is faster, and the chip simulation of acquisition, more close to actual conditions, also has higher scientific research value.At present, conventional roll adjusting mechanism has explosion type, shooting type and spring, and it is best that explosion type " freezes " effect, cutter can be made to depart from workpiece fast by the thrust of blast, but be difficult to determine due to dose, dangerous large, blast all can produce damage to whole device, few application to the utmost; Shooting type, is utilize powder burning in nail shooting pill as power, promotes piston rod and steel nail high-speed motion, clashes into roll setting block etc. and makes cutter depart from workpiece, and its shortcoming is that apparatus structure is complicated and danger coefficient is high; Spring roll adjusting mechanism utilizes the elastic force of spring that cutter is departed from, and this roll setting mode, has good effect when cutting speed is lower, but along with the raising of cutting speed, and it is less that the lathe tool that spring provides departs from acceleration, is difficult to obtain desirable chip simulation.
Super-magnetostrictive drive core component is giant magnetostrictive material, this material is widely used because of its advantage such as at room temperature mechanical energy-energy conversion rate is high, energy density is large, good reliability, type of drive are simple, the response time that giant magnetostrictive material produces magnetostrictive effect is extremely short, the effect of magnetization and generation stress almost occurs simultaneously, utilize this feature, may be used for the Electromagnetic Drive original paper of ultra-high sensitive.
Summary of the invention
Problem to be solved in the utility model is the deficiency existed for prior art, designs a kind of handling safety, can obtain the roll adjusting mechanism of desired cut root under high-speed cutting condition (> 1000m/min).
For achieving the above object, the utility model provides a kind of ultra-magnetic telescopic formula high-speed cutting roll adjusting mechanism, and the technical scheme adopted is.
Ultra-magnetic telescopic formula high-speed cutting roll adjusting mechanism, mainly comprise, knife bar, knife rest, super-magnetostrictive drive, straight pin, alternating electromagnet, magnet, holding screw, it is characterized in that: knife bar end is connected with knife rest by straight pin, knife rest is fixed with alternating electromagnet, is fixed by holding screw, and knife bar is fixed with magnet by holding screw, super-magnetostrictive drive end is fixed on knife rest, and extension bar contacts with knife bar.
Below the technical solution of the utility model is described further.
Aforesaid ultra-magnetic telescopic formula high-speed cutting roll adjusting mechanism, it is characterized in that, described alternating electromagnet and the suction surface of magnet coincide.
Aforesaid ultra-magnetic telescopic formula high-speed cutting roll adjusting mechanism, it is characterized in that, described knife bar can rotate around straight pin.
Usefulness of the present utility model is: ultra-magnetic telescopic formula high-speed cutting roll adjusting mechanism roll setting speed of the present utility model is fast, the response time of the magnetostrictive effect that super-magnetostrictive drive produces is extremely short, and magnetization produces the time of stress effect about microsecond; The potential safety hazards such as super-magnetostrictive drive and electromagnet are all by Electromagnetic Control, and operating personnel can operate outward whole process at safe distance, chip splashing large without roll setting noise.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in more detail: as shown in Figure 1, Figure 2, Figure 3 shows, ultra-magnetic telescopic formula high-speed cutting roll adjusting mechanism, primary structure comprises: 1 knife bar, 2 knife rests, 3 super-magnetostrictive drives, 4 straight pins, 9 magnet, 11 holding screws, 12 alternating electromagnets.First by bolt, 2 knife rests are fixed on lathe, 9 magnet are attracted to the 12 alternating electromagnet indirect currents fixing by 11 holding screws, start lathe to cut workpiece, after lathe spindle rotating speed reaches setting cutting speed, to 12 alternating electromagnet power-off, logical Opposed crossing electricity, 12 alternating electromagnets become repulsive force to 9 magnet from attraction, simultaneously to 3 super-magnetostrictive drive energisings, 3 super-magnetostrictive drives produce stress, 1 knife bar is acted on by extension bar, the acting in conjunction of the pressure that 1 knife bar is subject to 3 super-magnetostrictive drives downward and 12 alternating electromagnets, rotate around 4 straight pins with higher speed, depart from workpiece.Stop lathe, close the power supply of super-magnetostrictive drive and alternating electromagnet, complete whole cutting roll setting experiment.
