Description
Technical field
The utility model is a kind of electrical type electric cylinder, belongs to building engineering field, relates to multiple anti-folding and anti-pressing Materials Testing Instrument.
Background technology
The anti-folding of anti-folding and anti-pressing testing machine of current technology and crush resistant portion are all the structures adopting hydraulic cylinder, same oil sources power section, large-tonnage crush resistant portion should be controlled, the anti-folding part controlling little tonnage is again divided, because anti-folding part is divided, tonnage is little, low oil pressure, to oil temperature and leakage sensitivity, often causes anti-folding part to divide control weak effect, control precision is low, and calibration result is unstable.
Tradition anti-folding and anti-pressing testing machine, can not carry out anti-folding and anti-pressing test, can only carry out resistance to compression or bending test separately, test operation step is many simultaneously, complex operation, operating personnel's fatiguability, failure rate is high, during one tunnel work, another road is in idle condition, and machinery utilization rate is low.
The anti-folding and anti-pressing testing machine of current technology, anti-folding and anti-pressing testing machine shares a hydraulic oil container, in process of the test, has road oil liquid leakage and a pollution, all can affect the job stability on another road.If with two fuel tanks, then make again the volume of testing stand too huge, carrying inconvenience, occupied ground is too much.
Tradition sliding poise type cement mortar electric bending testing machine, automaticity is low, and need artificial reading rider position, certainty of measurement is low, high to the competency profiling of personnel, and easily makes mistakes, and can not carry out the networking of test data.
Summary of the invention
1. the technical problem that will solve
1.1 on traditional anti-folding and anti-pressing testing machine, and anti-folding hydraulic cylinder is subject to the impact of hydraulic fluid temperature and leakage, to oil temperature and leakage sensitivity.
1.2 anti-folding oil cylinder ascending and descending process control effects are poor, and control precision is low.
2. technical scheme
2.1 replace traditional hydraulic cylinder piston with ball screw, remove the Hydraulic Elements that anti-folding hydraulic cylinder is all, according to profile and the installation dimension of anti-folding hydraulic cylinder, redesign internal structure, increase piston guide mechanism and lead limit switch, manufacture and be assembled into new a kind of anti-folding and anti-pressing testing machine electric cylinder.
2.2 motor via reducer structures are connected with ball screw, by receiving the instruction of controller, control the rotation of motor, thus the screw mandrel piston on ball screw are done rise or descending motion, replace rising or the descending motion of hydraulic cylinder piston.
3. beneficial effect
3.1 without the need to oil pump, and adopt motor to drive, during work, noise reduces, and without hydraulic oil, Installation and Debugging and operational environment can keep clean and tidy, without the need to Hydraulic Elements such as supporting hydraulic valve, oil pumps.
The precision of 3.2 risings or descending motion is high.
Accompanying drawing explanation
Accompanying drawing is the electronic cylinder structure schematic diagram of a kind of anti-folding and anti-pressing testing machine.
Being labeled as in figure: protecting crust (4), cylinder body shell (2), screw mandrel piston (1), piston guide mechanism (5), lead limit switch (9), ball screw (3), bearing group (6), reducing gear (7), motor (8).
Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in drawings, a kind of anti-folding and anti-pressing testing machine electric cylinder, structure is enclosed within cylinder body shell (2) outward primarily of described protecting crust (4), prevents foreign material from entering the inside of electric cylinder; Screw mandrel piston (1) is arranged on the nut of ball screw (3), piston guide mechanism (5) and lead limit switch (9) are arranged on screw mandrel piston (1) side, and contact with cylinder body shell (2) simultaneously, carry out spacing and guiding; Ball screw (3) is connected by the output of bearing group (6) with reducing gear (7), the output of motor (8) is connected with the input of reducing gear (7), profile after assembling is identical with anti-folding hydraulic cylinder with installation dimension, the anti-folding oil cylinder on replaceable anti-folding and anti-pressing machine.
During electric cylinder work, motor (8) accepts the instruction of controller, ball screw (3) is driven to rotate by reducing gear (7), make the screw mandrel piston (1) be arranged on feed screw nut increase or decline, thus the function realizing the rising of replacement liquid pressure cylinder piston or decline, the size of control piston (1) rising or the speed declined and load is carried out by the rotating speed controlling motor (8).
A kind of anti-folding and anti-pressing testing machine electric cylinder main application and feature:
1, adopt high precision ball screw mandrel and high accuracy reducing gear, transmission accuracy is high.
2, the hydraulic cylinder mounting means with traditional anti-folding and anti-pressing testing machine is identical, and institute takes up space little.Conveniently hydraulic cylinder changing is become anti-folding and anti-pressing testing machine electric cylinder, and without the need to amendment in testing machine rack construction, it is very convenient that installation is changed.
3, without the need to oil pump, adopt motor to drive, during work, noise reduces.Without hydraulic oil, Installation and Debugging and operational environment can keep clean and tidy.
4, without the need to supporting hydraulic valve, the Hydraulic Elements such as oil pump.
Claims (2)
1. an anti-folding and anti-pressing testing machine electric cylinder, primarily of protecting crust (4), cylinder body shell (2), screw mandrel piston (1), piston guide mechanism (5), lead limit switch (9), ball screw (3), bearing group (6), reducing gear (7), motor (8) composition, it is characterized in that: replace traditional hydraulic cylinder piston with ball screw (3), piston guide mechanism (5) and lead limit switch (9) are arranged on screw mandrel piston (1) side, contact with cylinder body shell (2) simultaneously.
2. a kind of anti-folding and anti-pressing testing machine electric cylinder according to claim 1, it is characterized in that: described motor (8) accepts the instruction of controller, ball screw (3) is driven to rotate, make screw mandrel piston (1) increase or decline, thus the function realizing the rising of replacement liquid pressure cylinder piston or decline.
