Deep trouth captures and release manipulator
Technical field
The present invention relates to electromechanical device and manipulator civil engineering and technical field of measurement and test application.
Background technology
Manipulator is a kind of complicated, high precision machining mechanical equipment, is that one kind can imitate human hand to by fixation
Program captures the automatic pilot of object.Common mechanical hand clamps and relies on frictional force crawl end face smooth by mechanical part
Thing block is, it is necessary to certain grasping part.In civil engineering and technical field of measurement and test, have in long and narrow and deep trouth accurate control crawl and
Needs with discharging the smooth irony thing block in end face.In some cases .., such iron block be in addition to it can move in one direction,
Without crawl space on two other direction;Thus for the long and narrow and deep trouth space in no side holding space, existing manipulator
Crawl operation be difficult to carry out.If attracting iron block from movable direction by permanent magnet, the release of iron block can not be implemented;And
At present electromagnetization manipulator in long and narrow and deep trouth space to crawl and it is not accurate with the time control of release.
The content of the invention
In order to overcome common mechanical hand complicated, feature does not reach accurate control crawl and and release end in deep trouth
The problem of smooth irony thing block in face, there is provided it is a kind of simple in structure, it is easily fabricated to be suitable for being precisely controlled crawl in deep trouth and release
Put the manipulator of irony thing block.
The present invention adopts the technical scheme that:Using driving stepper motor zigzagging bar, to realize manipulator along deeply
Groove direction is freely lifted;Control electromagnetism ferromagnetism to produce and disappear by carrying out relay switch by microprocessor system, with
Deep trouth crawl and release iron block are realized when closing manipulator lifting.
Above-mentioned stepper motor, can rotate clockwise and rotate counterclockwise as needed.
Above-mentioned electromagnet, can accurately control relay switch by microsystem the time of crawl and releaser block.
Above-mentioned electromagnet, by electromagnetic force, is easy to capture variously-shaped irony thing block in small space, and provide stable
Grasp force.

Embodiment
As shown in Figure 1, deep trouth crawl includes with the mechanical hand of release:Electromagnetic relay 4, electromagnet 3, stepper motor 2, lifting
Mechanism 1.
Electromagnetic relay 4 is by CPU output control drivers, and then the switch of control electromagnetic relay 4, so as to produce electricity
Magnetic effect.The voltage that electromagnetic relay 4 uses is 24V.
Programme-control can be set by CPU, the accurate time for controlling electromagnet 3 to capture irony thing block and releaser block.
As shown in Figure 1, using electromagnet 3, when capturing and discharging irony thing block, answering for common mechanical hand can be greatly simplified
Miscellaneous structure.It is long and narrow with deep trouth space in, the present invention than common mechanical hand is easier to capture and discharges irony thing block.
Stepper motor 2 can adjust rotation direction by controlling, and electromagnet 3 declines when rotating in a counterclockwise direction, when close
Electromagnetic relay 4 is opened during irony thing block, adsorbs irony thing block using electromagnetic force, when completing absorption, stepper motor 2 is with clockwise
Direction rotates lifting irony thing block.Stepper motor 2 also adjustable rotating speed to adjust the lifting speed of object.
Elevating mechanism 1 can choose the rack 6 of different length according to the depth of groove.
As shown in Fig. 2, stepper motor 2 is made of motor and its protection shell 5, motor and its protection shell 5 are positioned at electricity
The top of magnet 3, is connected with top plate 9.
9 middle perforate of top plate.
Rack 6 is connected with electromagnet 3 through top plate 9, is lifted with band motor magnet 3.
As shown in figure 3,3 conducting wire of electromagnet is connected to microcomputerized controller with motor leads via conductor connecting pipe 10.
Rack 6 is connected with rack-track 13.
Stepper motor 2 is moved with carry-over bar 6, and rack 6 is connected with rack guide rail 13 forms elevating mechanism 1, elevating mechanism 1
Move vertically along fixed guide rail 14.
Motor and its protection shell 5 are connected with guide rail motor connecting plate 11.
Fixed guide rail 14 is connected with linear bearing connecting plate 12.
Linear bearing connecting plate 12 is connected with guide rail motor connecting plate 11.
