A kind of sample for testing machine automatic centring device
Technical field
The present invention relates to a kind of mechanical type automatic centring device, particularly a kind of sample for testing machine automatic centring device.
Background technology
At present, sample for testing machine centering is carried out for manual range estimation, and the operating personnel's gimmick difference or the collimation error bring than mistake for sample centering.
Summary of the invention
Technical matters to be solved by this invention is: a kind of sample automatic centring device is provided, has pointed cylinder clamping sample synchronously for two that utilize common cylinder to advance, reached the reliability of sample automatic centering, eliminated the manual operations and the collimation error.
The objective of the invention is to be achieved through the following technical solutions:
This sample for testing machine automatic centring device is characterized in that: it comprises the common cylinder that the bearing that is fixedly arranged on substrate tightens, and the fixed head that touches with piston rod on the common cylinder; Described fixed head is connected with on the slide block that is free to slide along the substrate bearing of trend; It is two finger cylinders of finishing the motion of finger centering of support with two links that described slide block is provided with one group; Simultaneously, on the substrate of slide block bearing of trend, be provided with a bracing frame of shelving sample.
According to this sample for testing machine automatic centring device that technique scheme realizes, not only simple in structure, easy to use; By utilizing common cylinder to promote finger cylinder, finger cylinder clamping sample, to reach the sample automatic centering, eliminated operating personnel because the gimmick difference and the collimation error, cause that sample centering brings than mistake, can effectively improve the sample accuracy of alignment.
Description of drawings
Accompanying drawing is the structural representation of sample for testing machine automatic centring device.
Among the figure: the common cylinder 2-of 1-bearing 3-fixed cap 4-slide block 5-link 6-finger cylinder 7-substrate 8-sample 9-bracing frame
Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments:
See also accompanying drawing, a kind of sample for testing machine automatic centring device is characterized in that: it comprises the common cylinder 1 that the bearing 2 that is fixedly arranged on substrate 7 tightens, and the fixed head 3 that touches with piston rod on the common cylinder 1; Described fixed head 3 is connected with on the slide block 4 that is free to slide along substrate 7 bearing of trends; It is two finger cylinders 6 of finishing the motion of finger centering of support with two links 5 that described slide block 4 is provided with one group; Simultaneously, on the substrate 4 of slide block 4 bearing of trends, be provided with a bracing frame 9 of shelving sample 8.
Sample for testing machine automatic centring device of the present invention is to use like this:
This sample for testing machine automatic centring device connects computer instruction, and the piston rod on the common cylinder 1 advances to the right, and fixed head 3 promotes slide blocks 4, link 5 and finger cylinder 6 and together is moved to stroke to the right at this moment.Then under computer instruction.Two finger cylinders, 6 clamping samples are to reach sample automatic centering purpose.
This easy device both can have been eliminated the operating personnel's gimmick difference and the collimation error, brought than the also very effective raising sample accuracy of alignment of mistake for sample centering.
In actual design, the piston rod of described common cylinder 1 both can be directly and fixed head directly be fixed together, also can take to contact ways of connecting.
