Description
Technical field
The invention belongs to industrial automation, be specifically related to the improvement of a kind of linear electric motors positioning system structure.
Background technology
Module the most on the market, also known as industrial machinery people, is mostly the mobile platform driven by motor, has half-sealed and complete close dust protected structure.Having two kinds of kinds of drive, a kind of is to have synchronous belt type transmission at a high speed, and it is to be arranged on the power transmission shaft of straight line module both sides by belt, then fixes one piece on belt for the slide block increasing equipment work-piece.When there being input, by driving belt to make slide block movement；Another kind is by having certain rigidity, and the ball leading screw driving that precision is high, and it is the motion that is in line by convert rotational motion.
At present, the exploitation of existing straight line module all faces a problem, and precision is difficult to control to, especially belt drives, and owing to the self property of belt determines, it does not has precision to say.
Summary of the invention
The present invention is aiming at the problems referred to above, it is provided that a kind of simple in construction, the linear electric motors alignment system that precision is high.
For realizing the above-mentioned purpose of the present invention, the present invention adopts the following technical scheme that, the present invention includes that frame, frame both sides are provided with X-axis crossbeam, it is characterized in that: be provided with X-axis linear electric motors on two X-axis crossbeams, the drive end of two X-axis linear electric motors and the two ends of a Y-axis crossbeam are connected；It is provided with X-axis grating scale on two X-axis crossbeams, described Y-axis crossbeam is provided with X-axis read head corresponding to two X-axis grating scales；Being provided with Y-axis linear electric motors on described Y-axis crossbeam, the drive end of Y-axis linear electric motors is connected with Z-axis mechanism；It is provided with Y-axis grating scale on described Y-axis crossbeam, described Z-axis mechanism is provided with Y-axis read head corresponding to Y-axis grating scale.
As a preferred embodiment of the present invention, outside described X-axis linear electric motors and Y-axis linear electric motors, it is provided with guard shield.
As the another kind of preferred version of the present invention, the two ends of described X-axis crossbeam are provided with Bunper assembly, and described Y-axis crossbeam is provided with collision block corresponding to Bunper assembly.
Beneficial effects of the present invention: 1, the present invention uses linear electric motors to be driven, linear electric motors need not move through intermediate conversion mechanism and directly produce linear motion, make structure be greatly simplified, and movement inertia reduces, and dynamic response performance and positioning precision are greatly improved；Also improve reliability simultaneously, saved cost, make manufacture and safeguard easier.
2, the present invention uses linear electric motors, being easily able to its mover magnetic suspension support, so that remain certain air-gap between mover and stator and do not contact, this eliminates the need for the contact frictional resistance between fixed and moving son, so, transmission parts do not wear and tear, and can be greatly reduced mechanical loss, it is to avoid the noise that towing cable, cable wire, gear are caused with belt pulley etc., thus improve whole efficiency, and its acceleration is big, speed is fast, is especially suitable for high-speed straight-line motion.
3, the present invention uses grating closed loop control, and positioning precision is up to 0.1～0.01mm.The driving system of linear motor of the application feedforward can reduce tracking error more than 200 times.Owing to the dynamic characteristic of moving component is good, respond sensitive, add becoming more meticulous of INTERPOLATION CONTROL OF PULSE, nanoscale control can be realized.
4, the stroke of the present invention is unrestricted.Traditional lead screw transmission is limited by leading screw manufacturing process, general 4m, and longer stroke needs spreading leading screw, from manufacturing process or on performance the most undesirable.And using linear electric motors to drive, stator can infinitely lengthen, and manufacturing process is simple, and joint length can reach 6 meters, and can extend, the longest up to 40 meters.
5, strong adaptability of the present invention.The primary iron core of linear electric motors can be integral by epoxy resin envelope, there is preferable anticorrosion, humidity resistance, it is easy to use in the environment of moist, dust and harmful gas, and, the present invention is provided with guard shield, can ensure that the pollutant such as the dust in Factory Building will not enter in linear electric motors, affect the operating of linear electric motors.
