Second mounting hole 140.The pilot sleeve 530 is connect at second mounting hole 140 with the centering disk 100.Described
The drive rod 511 of two driving cylinders 510 passes through the pilot sleeve 530 and connect with the mounting bracket 520.So set, leading
Guiding, protective effect can be played to the drive rod 511 of the second driving cylinder 510 to sleeve 530, further promote the reliable of driving
Property.
Optionally, the planar stretch device further includes (not showing in figure for detecting the sensor of stretch recovery forces
Out), convenient for carrying out detection test to workpiece, so that the planar stretch device of the present embodiment can not only process workpiece,
It can also play the role of test to workpiece.
Planar stretch device described in the present embodiment, be applicable to the workpiece such as thin-film material, rubber material etc. axial planes
Repeated stretching can be very good to meet multi-drawing by using connecting rod 410, centering disk 100 and the first driving mechanism 300, high
Strength pull can carry out controllable stretching and retraction simultaneously, can actively provide a power in workpiece retraction, realize and stretch retraction
The function of power supplement；By using cylinder driving method, after blowing can automatic clamping workpiece, be not required to carry out supplied materials special
Different processing, more meets production requirement；410 device of connecting rod adds the design of guide rail 431, so that during stretching, workpiece motion s rail
Mark is more stable, is conducive to the yield and rate that promote processing.The planar stretch device, in actual work can be with small
The planar materials of modulus 1mpa-100mpa are stretched 4-5 times in 30 seconds beats, and are bounced back, the energy in multiple stretching retraction
The depth of parallelism of repetitive positioning accuracy and processed sample is enough persistently kept, intensity and reliability can satisfy production needs.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art
It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to protection of the invention
Range.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
