Abstract
The utility model relates to a rotary linear displacement sensor which comprises shaft seats, a support plate, rotary encoders, a chuck, a linear motion unit, a synchronous belt and synchronous wheels, wherein the shaft seats are installed at both ends of the support plate, each shaft seat comprises a fixed shaft seat and a shaft seat with a fine adjustable center distance, a rotary encoder is installed on the fixed shaft seat, the synchronous wheels are installed on the two shaft seats and connected through the synchronous belt, and the synchronous belt is connected with the linear motion unit through the chuck. The rotary linear displacement sensor has a simple and reasonable structure and low cost, is more convenient in directly converting a linear displacement amount to an angle displacement amount by the rotary encoders and reading the angle displacement amount and has the maximum displacement of 500mm.
Description
Technical field
The utility model relates to linear displacement transducer, relates in particular to a kind of swinging linear displacement transducer.
Background technology
At present, it is reciprocating in the cartridge type enclosed cavity that conventional accurate linear displacement transducer is generally accurate rod member, reads shift value by analog quantitys such as voltage or electric currents, and the price of this device is very expensive, accurate rod member rigidity is relatively poor, and maximum displacement value is usually below 200mm.
Summary of the invention
At above-mentioned shortcoming, the utility model technical issues that need to address provide a kind of swinging linear displacement transducer.
The technical solution adopted in the utility model is:
The swinging linear displacement transducer, comprise axle bed, back up pad, rotary encoder, chuck, straight line mobile unit, band and synchronizing wheel synchronously, the back up pad two ends all are equipped with axle bed, on one of them axle bed rotary encoder is installed, on two axle beds synchronizing wheel is installed all, two synchronizing wheels are by band connection synchronously, and band is connected with the straight line mobile unit by chuck synchronously.
Described axle bed is fixedly an axle bed and a fine-tuning centre distance axle bed.
Described rotary encoder is fixed in fixedly on the axle bed.
The utility model has the advantages that: simple and reasonable, cheap, by rotary encoder straight-line displacement amount is directly changed into angular displacement and reads out, convenient, and maximum displacement reaches 500mm.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Wherein: 1, axle bed, 2, support plate, 3, rotary encoder, 4, chuck, 5, band synchronously, 6, synchronizing wheel, 7, the straight line mobile unit.
Embodiment
In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.
As shown in Figure 1, swinging linear displacement transducer of the present utility model, comprise axle bed 1, back up pad 2, rotary encoder 3, chuck 4, straight line mobile unit 7, be with 5 and synchronizing wheel 6 synchronously, back up pad 2 two ends all are equipped with axle bed 1, axle bed 1 is fixedly an axle bed and a fine-tuning centre distance axle bed, rotary encoder 3 fixedly is installed on the axle bed, and on two axle beds 1 synchronizing wheel 6 is installed all, two synchronizing wheels 6 are by being with 5 to connect synchronously, are with 5 to be connected with straight line mobile unit 7 by chuck 4 synchronously.
Below operating process of the present utility model is described further: when straight line mobile unit 7 moves, do corresponding rotatablely moving by being with 5 drive synchronizing wheels 6 synchronously, rotary encoder 3 is read the anglec of rotation of synchronizing wheel 6, can calculate the straight-line displacement value, convenient, and maximum displacement reaches 500mm, and is simple and reasonable like this, and price is also cheap.
