Background technology
Metallographic experiment is a laboratory of mechanical major.This experiment needs experimenter that test button is placed on pre-mill and is polished, until plane is smooth.Pre-mill, in high speed rotating, flies in order to prevent that sample from being beaten, and experimenter must firmly tightly press test button on pre-mill.Because the time is longer, and hand can not arbitrarily move.This just causes this experiment to have certain danger.Just occurring in laboratory that a lot of samples are beaten flies, and causes the impaired accident of pre-mill.And because the hand reason of being inconvenient to move, what cause polishing metal is a part for sand paper forever, and other part does not make full use of.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of pre-mill sample clamping device, can solve the clamping problem of test button, avoids sample to be beaten and flies, and can control the contact force of test button and sand paper, further, can make full use of sand paper.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of pre-mill sample clamping device, comprise bearing, rest base is provided with installation portion, and bearing is provided with parallel guide rail and leading screw, slide block and guide rail are slidably matched, slide block is provided with screw, and screw is connected with threads of lead screw, and slide block is provided with mobile jib, clamping beam is movably arranged on mobile jib, and the termination of clamping beam is provided with clamping device;
Mobile jib termination is installed with compression beam, and compression beam termination is fixedly connected with compressor arm, and compressor arm is provided with the spring for compressing clamping beam.
Leading screw is by bearing expansion bearing on bearing, and leading screw termination is connected with rocking handle.
Described compressor arm is provided with fastening slide block, and fastening slide block is provided with trip bolt, and fastening slide block is positioned at the top of spring, is also provided with compress gasket in the bottom of spring.
Clamping beam passes compressor arm, and forms and be slidably matched with compressor arm.
In described clamping device, clamping head is connected with retaining sleeve, and described clamping head termination is provided with the tapered pawl of multiple combination follower heads, and retaining sleeve inwall is provided with conical section.
A kind of pre-mill sample clamping device that the utility model provides, by this clamping device is arranged on pre-mill, can solve the clamping problem of test button easily, avoids occurring that in pre-grinding process, sample is beaten the problem flying, and has improved security; Further, the spring of setting, in conjunction with fastening slide block, can be controlled the contact force between test button and sand paper.By the nut screw mechanism arranging, test button can be by the rotation of rocking handle along the moving radially of pre-mill, thereby make full use of sand paper.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail:
