Abstract

The utility model discloses a voice motor moving platform, comprising two voice coil motors and a sliding block. The slide block is installed between the two voice coil motors and rotors of the two voice coil motors are connected to the two sides of the sliding blocks. The two motors of the voice coil motor moving platform are symmetrically arranged on two sides of the sliding block, and the power is provided by adopting a one-push-and-one-pull mean, so that the voice coil motor moving platform is big in push, and the structure and stress are identical in the process of moving back and forth.

Description

A kind of voice coil motor motion platform
Technical field
The utility model belongs to voice coil motor field, relates in particular to a kind of voice coil motor motion platform.
Background technology
Voice coil motor has advantages of that thrust is large, fast response time, has been widely used in needing the motion control field of high-speed response, especially in accurate semiconductor equipment, has obtained especially extensive application; Prior art, in the time using the motion platform of an axle of voice coil motor composition, generally connects: 1 voice coil motor is arranged on a side of slide block in the following ways, and fortune of voice coil motor is connected with slide block, drives slide block movement by mover; There are following 2 weak points in prior art: the thrust of (1) single voice coil motor is limited, and higher thrust and acceleration can not be provided; (2) fortune son band movable slider do past, while returning motion, past, to return one of the suffered power of both direction slide block be that thrust, one are pulling force, may cause whole motion platform toward, to return system rigidity on both direction different.
Summary of the invention
The utility model provides a kind of voice coil motor motion platform, can solve the deficiency that prior art exists, it can provide the thrust larger than prior art, and toward, return in direction and can accomplish the mechanical structure of full symmetric and identical stress, can guarantee whole motion platform past, to return when motion system rigidity identical.
Scheme of the present utility model specifically describes as follows: a kind of voice coil motor motion platform, comprises 2 voice coil motors and a slide block; 2 voice coil motors are symmetrically distributed in the both sides of slide block, and the mover of 2 voice coil motors is connected with the both sides of slide block respectively.
A kind of voice coil motor motion platform provided by the utility model, because used 2 voice coil motors jointly to drive a slide block, can provide larger thrust and acceleration than prior art; Again because 2 voice coil motor symmetries are arranged on slide block both sides, the Machine Design of whole motion platform can accomplish that both sides complete symmetry, do past, return when motion, slide block always has a side to be subject to thrust driving, opposite side under tension drives, slide block past, to return stressing conditions identical, can ensure whole motion platform toward, to return system rigidity on both direction in full accord.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of voice coil motor motion platform provided by the utility model.
Primary clustering symbol description in Fig. 1
1: slide block; 2: mover; 3: stator;
2 and 1 stator 3 of 1 mover shown in Fig. 1 forms 1 voice coil motor, has 2 voice coil motors and be distributed in the both sides of slide block 1.
Embodiment
Refer to Fig. 1, voice coil motor has 2, is arranged on respectively the both sides of slide block 1; Voice coil motor is made up of mover 2 and stator 3; Wherein the mover 2 of 2 voice coil motors is connected with the both sides of slide block 1 respectively.
Working method: the slide block 1 in the middle of the mover 2 of 2 voice coil motors drives jointly in the mode of push and pull respectively moves; Slide block 1 past, return when motion, slide block 1 always has a side to be subject to thrust driving, opposite side under tension drives, slide block past, to return stressing conditions identical, the thrust (or pulling force) that the actuating force obtaining equals 2 voice coil motors is added, thus a kind of voice coil motor motion platform provided by the utility model can provide larger thrust and past, return the identical stressing conditions of both direction.

Claims (2)

1. a voice coil motor motion platform, comprises 2 voice coil motors and 1 slide block, it is characterized in that: described slide block is arranged in the middle of 2 voice coil motors, and the mover of 2 voice coil motors is connected with the both sides of slide block respectively.
2. a kind of voice coil motor motion platform according to claim 1, is characterized in that: described voice coil motor is made up of stator and mover.
