Abstract
Disclosed is a signal feedback device for a linear motion end, comprising a toothed wheel I and a toothed wheel II which are connected through a toothed belt, wherein an encoder is installed on and coaxial with the toothed wheel I. In the utility model adopting the technical scheme, end linear motion is converted into rotary motion by driving the toothed belt and the toothed wheels, and linear motion of a mechanism is controlled by measuring angle displacement and feeding the measured angle displacement back to a control system. Therefore, the signal feedback device for a linear motion end in the utility model is suitable for linear motion position detection in which the demand for accuracy is low, and usually the position accuracy is not greater than 1mm/1000mm. The signal feedback device is simple in structure, low in cost and applicable to end position feedback of linear motion.
Description
Technical field
The utility model relates to the terminal signal feedback device of a kind of rectilinear motion.
Background technology
The rectilinear motion of plant equipment is often through realizations such as pinion and rack, screw-nut body, hydraulic mechanisms.For guaranteeing the accuracy of mechanism kinematic, usually adopt feedback terminal position information such as position detecting element such as grating chi, make the accurate control gear motion of control element.
The grating chi is to be specifically designed to the element that straight-line displacement is measured, and is made up of scale and slide rule.The optical grating ruler measurement precision is high, can reach 3 microns/1000 millimeters accuracy class.The grating chi is had relatively high expectations to installation accuracy, environment for use, and cost is higher.
Summary of the invention
The purpose of the utility model provides the terminal signal feedback device of a kind of rectilinear motion simple in structure, that cost is low.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
The utility model comprises toothed wheel I and the toothed wheel II that is connected through cog belt, on the described toothed wheel I scrambler is installed, and scrambler is coaxial with the toothed wheel I.
Described scrambler is an increment of rotation formula scrambler.
Adopt the utility model of technique scheme, adopt the cog belt and the toothed wheel kind of drive that terminal rectilinear motion is converted into and rotatablely move, through the displacement that takes measurement of an angle, feed back to control system, the rectilinear motion of control gear.Thereby the utility model is applicable to the rectilinear motion position probing that accuracy requirement is not high, and common positional precision is not more than 1mm/1000 mm.Simple in structure, cost is lower.Be applicable to straight-line terminal position feedback.
Description of drawings
Fig. 1 is the one-piece construction synoptic diagram of the utility model.
Embodiment
As shown in Figure 1, the utility model comprises the toothed wheel I 2 and toothed wheel II 4 that is connected through cog belt 3, on the described toothed wheel I 2 scrambler 1 is installed, and scrambler 1 is coaxial with toothed wheel I 2.Above-mentioned scrambler 1 is a preferred forms with increment of rotation formula scrambler.During work, scrambler 1 connects the input end of controller, and the output terminal of controller can connect digital display device, is used to show displacement.
The principle of work of the utility model is: scrambler and the coaxial installation of toothed wheel, and drive toothed wheel by cog belt and rotate, cog belt links to each other with moving component, directly feeds back its rectilinear motion distance.According to the pitch and the toothed wheel pitch diameter of cog belt and toothed wheel, can converse the corresponding relation of rectilinear motion distance with the scrambler anglec of rotation of moving component, thereby can come the movement position of controlled motion parts according to the signal of encoder feedback.
So, can the utility model be applied on the caliberating device at present, be used for straight-line displacement is converted into angle value, after converting, can on digital display meter, show displacement.
