Abstract
The utility model discloses a detecting arm with multiple degrees of freedom and consists of a flexible metal sleeve; wherein, the wall of the flexible metal sleeve is provided with a plurality of barometric cavities, and an air-guide tube communicated with the barometric cavities is arranged inside the flexible metal sleeve. Three barometric cavities are evenly distributed on the identical section of the flexible metal sleeve. When the detecting arm with multiple degrees of freedom is applied, all the barometric cavities are inflated, and the detecting arm can be bent freely taking the flexible sleeve as center under the action of the air pressure. In addition, the curvature is relative to the barometric proportion and the bending direction is relative to the pressure of all the cavities in the section, that is, the curvature and the bending direction can be adjusted freely. The detecting arm with multiple degrees of freedom has the advantages that the structure is reasonable, the operation is convenient and the detecting contactor can be protected.
Description
Technical field
The utility model discloses a kind of multiple degrees of freedom feeler arm, belongs to detection instrument and makes the class technical field.
Background technology
Modern detection system major part is to utilize sensor aesthesia, displacement, light intensity, chemical molecular etc.Sensor then needs to be installed on feeler or the feeler arm, and existing feeler arm major part is mechanical.A kind of multiple degrees of freedom space feeler is by the stepper motor of joint and angular transducer control and record displacement, and is another kind of by grating or hold the picking up and record of displacement implementation space point that grid isoline type displacement transducer utilizes X, Y, Z three directions.In this operation of many occasions is the bending that needs in space, and needs certain deformability, when this device is not seen as yet.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of simple in structure, easy to use, protection contact can realize the multiple degrees of freedom feeler arm of multiple motion.
The utility model is achieved through the following technical solutions:
The utility model includes flexible metal casing, wherein, is furnished with several atmospheric pressure cavities on the tube wall of described flexible metal casing, and the wireway that communicates with atmospheric pressure cavity is housed in the flexible metal casing.
Be evenly distributed with three atmospheric pressure cavities on the same cross section of described flexible metal casing.
When the utility model is used, give the inflation of each section atmospheric pressure cavity, under the effect of gaseous tension, feeler arm is that the center is free to bending with the flexible sleeve.And curvature is relevant with the ratio of air pressure, and bending direction is with relevant with each cavity pressure in the cross section.Be that curvature and bending direction are free to regulate, have rational in infrastructure, easy to use, can protect advantage such as detection contact.
Description of drawings
Figure is a sectional view of the present utility model;
Fig. 2 is of the present utility model to be sectional view.
Wherein, 1, atmospheric pressure cavity, 2, wireway, 3, flexible metal casing.
Embodiment
Embodiment: structure as shown in Figure 1 and Figure 2, the utility model includes flexible metal casing 3, is furnished with several atmospheric pressure cavities 1 on the tube wall of flexible metal casing 3, and the wireway 2 that communicates with atmospheric pressure cavity is housed in the flexible metal casing 3.Be evenly distributed with three atmospheric pressure cavities 1 on the same cross section of flexible metal casing.
As Fig. 1, when work, certain relatively high pressure is given in corresponding six chambeies, and certain relatively low pressure is given in six chambeies in addition, and flexible sleeve will be center curvature under the effect of air pressure, can realize bending effect as shown in the figure.Flexible metal casing can free bend but cannot be stretched.Curvature is to control by the pressure in each chamber.Control and write down the pressure data in each chamber by control system, every group of corresponding spatial point of pressure data.As long as that is to say the data that provide a series of controlled pressures, the picking up and record of point that just can the implementation space all directions.
Claims (2)
1, the multiple degrees of freedom feeler arm comprises flexible metal casing, it is characterized in that: be furnished with several atmospheric pressure cavities on the tube wall of described flexible metal casing, the wireway that communicates with atmospheric pressure cavity is housed in the flexible metal casing.
2, multiple degrees of freedom feeler arm according to claim 1 is characterized in that: be evenly distributed with three atmospheric pressure cavities on the same cross section of described flexible metal casing.
