Beneficial effect using above-mentioned technical proposal is engaged and can kept away using the T-slot of the shearing fixture block and pedestal
Exempt to shear and come off when fixture block adjusts angle by rotating to improve the safety and stability of shearing clamp, using the roller
Coordinated by positioning hole I with the deep-slotted chip breaker on shearing fixture block using gap and hand-tighten bolts are adopted by positioning hole II and shearing fixture block
The deep-slotted chip breaker gap cooperation avoided on only roller and shearing fixture block is combined with two kinds of regulation angular ways of interference fit to exist
Easily rotated when loaded and then ensure that the accuracy of angular adjustment, and can by hand-tighten bolts carries out dual fixation and improved to cut
The stability of fixture is cut, the angle shearing clamp that the shearing fixture block and pedestal coordinate can realize the function of continuous angle, again
Center of gravity can be remained without departing from center line.
The presser device includes cylindrical rollers, linear motion bearing guide pin bushing, top board, lower platen, baffle plate and interior six
Corner bolt, the cylindrical rollers and linear motion bearing guide pin bushing are engaged, and totally four, the baffle plate, the hexagon socket head cap screw is total to
12, four baffle plates are engaged fixation, the pressing plate with top board, lower platen by 12 hexagon socket head cap screws respectively
Device is engaged in the groove of top board and lower platen with grip device.
Beneficial effect using above-mentioned technical proposal is to use presser device that testing machine can be avoided to be pressed from both sides when loading because shearing
Tool is unable to transverse shifting and causes the phenomenon of direct conquassation, and then realizes shearing function of the shearing clamp to rock soil test piece.
The attachment means include positioning cylinder, bolt and contiguous block, the positioning hole that the positioning cylinder passes through lower platen
IV and the positioning of tester base, the contiguous block is used for top board and the positioning of pressure head of testing machine and bolt passes through contiguous block
Positioning hole III realize the fixation of contiguous block and top board.
Beneficial effect using above-mentioned technical proposal is that the attachment means can realize fixed between shearing clamp and testing machine
Position, the simplicity of connection.
