Test specimen can be made to deform, be difficult to ensure that the test requirements document size for being cut test specimen.Secondly, using such fixture clamping test pieces
When, test specimen is cantilever beam structure in cutting process, and cantilever part one side stress causes test specimen to become in cutting process
Shape, forms scarf, it is impossible to meet split requirement.Additionally, generally in experiment test specimen the product cycle is long, high cost, quantity has
Limit, there is a problem of producing waste material because cutting clamping is improper, it is most likely that influence experiment progress, while causing time, material
Deng waste.It is this in the urgent need to improving existing fixture, designs the clamping device based on linear contact lay in a kind of clamping.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, there is provided a kind of rock cutter test specimen clamping device, solution
The problems such as axial slip, flexural deformation that certainly existing fixture is produced in clamping test pieces.
In order to achieve the above object, the utility model includes main clamping device and auxiliary support apparatus；
The main clamping device includes hinged upper fixture body and lower clamp body, upper fixture body and lower clamp body group
Into for clamping by the cavity of cut part, the side of upper fixture body is provided with horizontal rectangular channel, and the side of lower clamp body is provided with
Bearing pin, is provided with eyelet bolt on bearing pin, eyelet bolt can be fixed in horizontal rectangular channel, and makes upper fixture body and lower clamp
Body is in close contact；
The auxiliary support apparatus include device body, are offered on device body for the fixed recess by cut part.
The side of the lower clamp body is provided with some longitudinal rectangular channels, and bearing pin is through all rectangular channels and is hinged on rectangle
In groove.
Longitudinal rectangular channel has four.
The upper fixture body and lower clamp body pass through gemel connection.
The upper fixture body and lower clamp body are wedge shape.
Pad is provided between the upper fixture body and lower clamp body.
The eyelet bolt top is provided with the nut for adjusting tightness.
The side of the upper fixture body is provided with handle.
The lower clamp body is bolted on workbench.
The auxiliary support apparatus bottom sets fixing hole.
Compared with prior art, the utility model by main clamping device and auxiliary support apparatus to being pressed from both sides by cut part
Hold, while be fixed by eyelet bolt and pressed, main clamping device uses the clamping that " three linear contact lays " is carried out to the face of cylinder
Mode, is exclusively used in the clamping of the certain test specimen of diameter；Another part is auxiliary support apparatus, is a vertical wedge, it is ensured that
Test specimen forms a simple beam structure in incision two ends, i.e. test specimen between the wedge and main clamping device, at utmost subtracts
Few influence of bending deformation quantity of the test specimen in working angles to cutting accuracy；The dismounting end of the present apparatus in the distal end away from cutter,
It is contaminated small, and the fixture need not typically move, and save the labour intensity of operating personnel, this clamping device is in clamping process
In all linear contact lays of contact with test specimen, when compaction forces are suitable, effectively prevent test specimen may occur in cutting process
Rotationally and axially sliding, the utility model simple structure, it is easy to process is easy to disassemble.
