Abstract
The utility model discloses a micro-displacement generator for a gate line phase shifter, which comprises a displacement platform, and the displacement platform is composed of a fixed station and a mobile station, the fixed station is elastically connected with the mobile station, a push rod hole is arranged on the fixed station, a push rod is arranged in the push rod hole, one end of the push rod is arranged on an edge cam, the other end is arranged on the mobile station, the edge cam is connected with a stepper motor. The utility model adopts a technical project which is on the basis of the push rod, the edge cam and the stepper motor, and has the advantages of simple and accurate displacement control and low cost.
Description
One, technical field
The utility model relates to a kind of micrometric displacement mobile platform, refers in particular to a kind of micrometric displacement generator of grid line phase-shifter.
Two, background technique
At present, micro-displacement apparatus adopts piezoelectric constant to produce micrometric displacement mostly, when producing the displacement of hundreds of micron, needs need usually to adopt piezoelectric constant heap and high voltage to implement, owing to use high voltage, therefore, complexity is set is difficult to accurate control, and can only be used for below 100 microns, and can not be used for excursion in the occasion of hundreds of nanometer to hundreds of micron micrometric displacement.
Three, technological scheme
Technical problem: the utility model provides a kind of micrometric displacement the control simple and easy to do and with low cost micrometric displacement generator of hundreds of nanometer to the hundreds of micron that be suitable for producing.
Technological scheme: a kind of micrometric displacement generator that is used for the grid line phase-shifter, comprise displacement platform, this displacement platform is made up of stationary platen and mobile substation, stationary platen is connected with mobile substation elasticity, be provided with push-rod hole on stationary platen, establish push rod in push-rod hole, an end of push rod is located on the end cam, the other end of push rod is located on the mobile substation, and end cam is connected in stepper motor.
Beneficial effect: 1. because the utility model has adopted end cam, make that bigger angular displacement can be converted into small straight-line displacement, promote mobile substation generation micrometric displacement by push rod, pulse controlled characteristic and end cam that stepper motor had, the technical measures of push rod make the utility model to control mobile substation easily and move, and can satisfy the required precision of such micro-displacement apparatus and the advantage of tool good linearity, in addition, the measure of this generation displacement of the present utility model need not to make piezoelectric constant produce the technical measures of required displacement with high voltage in the prior art, so the utility model also has advantage with low cost.2. the utility model is chosen to be the screw thread push boat with end cam, and the screw thread push boat can be a short screw, after push rod is located at its screw thread side, can make push rod rotatablely moving and axial translation takes place with the screw thread push boat, because the manufacturing of screw rod is simple, with low cost, so these technical measures that the utility model adopted have the advantage that cost more becomes cheap.3. because being the contact position of push rod and mobile substation, the relative position relation of push rod that the utility model adopted and mobile substation is positioned at the center symmetrical position of mobile substation, and mobile substation is an axially symmetric structure, so the utility model can guarantee mobile substation translation only takes place, and do not rotate, thereby to guaranteeing that precision is favourable.
