Further, described backboard is fixed on bolt and is positioned at that the both sides of guide pad are the most threaded clamp nut.
There is advantages that
1) present invention is provided with two pull pressure sensor, it is ensured that the precision of test, and only needs when processing and installation to ensure
The cylinder axis of pull pressure sensor, electric cylinder output shaft and cylinder is in the conplane depth of parallelism, it is not necessary to ensure electric cylinder
Output shaft and the axiality of cylinder axis.
2) in the present invention, the backboard of the erecting device of electric cylinder is adjustable, therefore can meet most of size electric cylinder
Install, and backboard is provided with electric cylinder rear end supporting mass, it is to avoid electric cylinder is shadow due to self gravitation formation bending strain
Ring measuring accuracy.
Accompanying drawing illustrates:
Fig. 1 is front view of the present invention.
Fig. 2 is top view of the present invention.
Detailed description of the invention:
The present invention is further illustrated below in conjunction with the accompanying drawings.
Such as Fig. 1 and Fig. 2, one electric cylinder performance test system of the present invention, including backboard 1, electric cylinder mounting groove 2, connect
Junctor 3, displacement transducer 4, cylinder mounting groove 5, electric cylinder rear end supporting mass 6, backboard fix bolt 7, guide rail 8, base 9,
Pull pressure sensor 10 and cylinder 11, electric cylinder mounting groove 2 and cylinder mounting groove 5 are respectively fixedly connected with in the left and right of base 9
Both sides, two connectors 3 are fixed between electric cylinder mounting groove 2 and cylinder mounting groove 5 in parallel to each other, two pull pressure sensor 10
Being fixed between two connectors 3, cylinder 11 is fixed in cylinder mounting groove 5, and the connector 3 on the cylinder axis of cylinder 11 and right side
Fixing connection, displacement transducer 4 is located on cylinder mounting groove 5, and the sensing shaft of displacement transducer 4 is solid with the connector 3 on right side
Fixed connection.The rear side of electric cylinder mounting groove 2 is located at by backboard 1, is provided with guide pad 21 on the lateral wall of electric cylinder mounting groove 2,
Guide rail 8 and backboard are fixed bolt 7 and are all actively plugged on this guide pad 21, and the rear end of bolt 7 fixed by the backboard of guide rail 8
All fix with backboard 1 and be connected.Fix on bolt 7 at backboard and be positioned at that the both sides of guide pad 21 are the most threaded fastening spiral shell
Female 22.Electric cylinder rear end supporting mass 6 is fixed on backboard 1.
Backboard 1 position in the present invention is adjustable, in order to meet the installation of different size electric cylinder.By backboard 1
When being adjusted to the position being suitable for, the clamp nut 22 fixed by backboard on bolt 7 is locked, and backboard is fixed bolt 7 and guide rail 8
Locked, thus fix backboard.
When detecting electric cylinder, being fixed on by electric cylinder in electric cylinder mounting groove 2, the output shaft of electric cylinder passes through connection method
Orchid is connected with the connector 3 in left side.Owing to the installation of electric cylinder is cantilever design, and the heavier mass of electric cylinder own, because of

Make electric cylinder output shaft move to the least significant end stretched out from retraction stroke least significant end, and gather the data of displacement transducer.Repeat
Carry out for several times, and the meansigma methods of each displacement size is designated as the maximum formation of electric cylinder.
During the lower maximal rate of test zero load: control to be minimum by cylinder thrust and pulling force, control electric cylinder with maximum simultaneously
Power work makes electric cylinder push rod from contraction end movement to stretching out end, and records the time of this process, is designated as stretching out stroke
Shortest time.In like manner, control electric cylinder and work with peak power, make electric cylinder push rod from stretching out end movement to shrinking end
End, and record the time of this process, it is designated as the shortest of retraction stroke.Measured range is respectively divided by this step surveyed
The stretching out when time obtained just can draw tested electric cylinder zero load is formed and retraction stroke maximal rate.
When testing maximum thrust or pulling force: controlling cylinder initial thrust is the 80% of electric cylinder normal thrust to be tested,
Simultaneously control electric cylinder with peak power work, make electric cylinder load operating mode under from retraction stroke end to stretching out stroke
End, can record described electric cylinder normally work, if can normally work, increases the load of cylinder, and increments is electric cylinder
Step before the 1% of rated load, and repetition.So circulate work, until electric cylinder push rod can not normally be released, and record
The maximum thrust that data are electric cylinder of pull pressure sensor in previous stroke when electric cylinder can not normally be released.In like manner,
Control the contraction of electric cylinder push rod and then can measure maximum pull.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For Yuan, can also make some improvement under the premise without departing from the principles of the invention, these improvement also should be regarded as the present invention's
