Abstract
The utility model discloses a clamp for clamping a metallic phase test piece. The clamp comprises a clamping device and a fixing device, wherein the clamping device comprises a clamping plate, a connecting plate and a connecting shaft, wherein the clamping plate is connected to the bottom of the connecting plate through a screw; the connecting plate is provided with a through hole in one end, and is arranged on the connecting shaft; the fixing device comprises a bolt and a butterfly nut; the bolt passes through the through hole in the other end of the connecting plate, and is connected with the butterfly nut. The butterfly nut is screwed, the connecting plate is driven to rotate around the connecting shaft under the action of the extruding pressure of the nut, and the clamping plate connected to the bottom of the connecting plate is driven to clamp the test piece under the action of the connecting plate. Compared with the prior art, the clamp is simpler in structure, easy to operate and solves the problems of low manual grinding efficiency of the test piece and unsafety. The clamp is lighter compared with other clamps, test can be performed conveniently, stably and safely, and the test accuracy is increased.
Description
Technical field
The utility model relates to a kind of fixture for the clamping of metallographic test specimen.
Background technology
In the time doing the grinding of metallographic test specimen, polishing test, conventionally directly with hand clamping, this is not only dangerous but also affect the degree of accuracy of experimental result.Under so high rotational speed, keep the clamping of test specimen steadily, reliably, to obtain accurate test findings as far as possible.
Summary of the invention
The problem that the utility model solves is on the buffing machine of High Rotation Speed, realizes, safety convenient to metallographic test specimen, clamps stably, to obtain desirable test findings.
A kind of fixture for the clamping of metallographic test specimen, comprise clamp device and stationary installation, described clamp device comprises clamping plate web joint and coupling shaft, and the web joint of clamping plate and top is to be connected by screw, and web joint one end is provided with that through hole is linked together by coupling shaft and around its rotation; Stationary installation comprises bolt and wing nut, and the other end of web joint is provided with through hole and is directly connected by bolt, tightens by wing nut.
For a fixture for metallographic test specimen clamping, described web joint is provided with two, is separately positioned on the both sides of coupling shaft.
For a fixture for metallographic test specimen clamping, described bolt connects two web joints.
Beneficial effect: compared with prior art, its structure is simpler, easy to operate for the utility model, has solved low, the uneasy congruent problem of artificial hand mill test specimen efficiency.The utility model is lighter and handier compared with other fixtures, can facilitate, steady, safe testing, and has improved the degree of accuracy of test.
Accompanying drawing explanation
Fig. 1 is structural representation front view of the present utility model;
Fig. 2 is structural representation vertical view of the present utility model.
In figure: 1 clamping plate, 2 screws, 3 web joints, 4 coupling shafts, 5 bolts, 6 wing nuts 7, test specimen.
Embodiment
Below in conjunction with drawings and Examples, the utility model is specifically described.
The utility model comprises clamp device and stationary installation bolt 5 wing nuts 6.
Described clamp device is made up of clamping plate 1 web joint 3 and coupling shaft 4, and clamping plate 1 are fixed on the bottom of web joint 3 by screw 2.
Described clamping plate 1 have web joint to drive, and realize the clamping to test specimen 7.
Described web joint 3 has two, and one end is connected to coupling shaft 4, other end erection bolt 5.
Described bolt is arranged on web joint 3, and wing nut 6 is installed on it.
When the utility model uses, test specimen 7 is placed between clamping plate 1, by the wing nut 6 tighting a bolt on 5, drives clamping plate 1 to draw close at the effect lower connecting plate 3 of extruding force, realize the clamping of clamping plate 1 to test specimen 7.
Compared with prior art, its innovative point is the utility model: adopt the mode of tightening wing nut, play more simply and effectively the effect to clamping test specimen; Do not need other loaded down with trivial details mechanism arrangement, fixture entirety is lighter, so effectively improved the degree of accuracy of test.
The above-mentioned embodiment of the utility model, just illustrates, and is not only, all within the scope of the utility model or the capping being equal in scope of the present utility model all surrounded by the utility model.
