The fluctuation of power, at the same because using hydraulic oil as working media due to it is larger to contamination.
Utility model content
The purpose of the utility model is to overcome the shortcomings that the above-mentioned prior art, a kind of linear motion device is provided, it should
Device has the characteristics that movement velocity is controllable, noise is small, at low cost, small and free of contamination.
In order to achieve the above objectives, linear motion device described in the utility model includes motor, controller, pedestal, first
Baffle, movement slide unit, drive link, riser, is transported for the attachment device that connects driven equipment and for detecting second baffle
The range sensor of dynamic spacing between slide unit and first baffle, wherein, first baffle and second baffle are both secured on pedestal, are passed
One end of lever is connected with the output shaft of motor, and the other end of drive link passes through the activity of the side of first baffle and second baffle
It is connected, movement slide unit is socketed on drive link, and moves and leadscrew-nut mechanism is formed between slide unit and drive link, and riser is erect
It is fixed on movement slide unit, attachment device is located at the top of riser, the output shaft of range sensor and the input terminal phase of controller
Connection, the output terminal of controller are connected with the control terminal of motor.
Display is further included, wherein, display is connected with the output terminal of controller.
The length of drive link is 5cm.
The utility model has the advantages that：
Linear motion device described in the utility model is connected to attachment device in concrete operations, by driven equipment
On, drive rod rotation is driven by motor, drive link drives movement slide unit linear motion, and movement slide unit is driven by attachment device
Driven equipment moves along a straight line, while detects the spacing between movement slide unit and first baffle in real time by range sensor, and
According to the moving displacement of the distance computation movement slide unit between movement slide unit and first baffle, and using the moving displacement as being driven
The move distance of dynamic equipment, when the move distance of driven device is equal to pre-determined distance, then controller control motor stops work
Make, therefore have the characteristics that movement velocity is controllable, noise is small, at low cost, small and free of contamination.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Wherein, 1 it is motor, 2 be attachment device, 3 be movement slide unit, 4 be drive link, 5 be riser, 6 be pedestal, 7 is the

The range sensor of dynamic spacing between slide unit 3 and first baffle 7, wherein, first baffle 7 and second baffle 8 are both secured to pedestal 6
On, one end of drive link 4 is connected with the output shaft of motor 1, and the other end of drive link 4 passes through first baffle 7 and second baffle 8
Side be movably connected and connect, movement slide unit 3 is socketed on drive link 4, and moves and leading screw spiral shell is formed between slide unit 3 and drive link 4
Parent agency, the setting of riser 5 are fixed on movement slide unit 3, and attachment device 2 is located at the top of riser 5, the output shaft of range sensor
It is connected with the input terminal of controller, the output terminal of controller is connected with the control terminal of motor 1；The utility model further includes aobvious
Show device, wherein, display is connected with the output terminal of controller；The length of drive link 4 is 5cm, and drive link 4 is screw rod.
In concrete operations, attachment device 2 with driven equipment is connected, drive link 4 is driven to rotate by motor 1,
Drive link 4 drive movement slide unit 3 move, by range sensor in real time detect movement slide unit 3 and first baffle 7 between away from
From, and according between the initial distance between movement slide unit 3 and first baffle 7 and current kinetic slide unit 3 and first baffle 7
Distance calculates the move distance of movement slide unit 3, and the move distance of the movement slide unit 3 is the move distance of driven equipment,
When the move distance of driven equipment is equal to pre-determined distance, then controller control motor 1 is stopped, and realizes driven equipment
Linear motion.
The utility model simple structure, convenient control securely and reliably, can effectively improve the power output of linear drive apparatus
Stability, positioning accuracy.The noise that equipment is avoided to run, and maintenance cost is relatively low.
