Description
Technical Field
The utility model relates to a rock mechanics nature experiment technical field specifically is a bi-polar face stone mill test piece anchor clamps of adjustable shape and size.
Background
In the construction of basic engineering such as metallurgy, coal, traffic, bridge tunnel, there are many scientific research projects to carry out the mechanics experimental study of a large amount of rocks in advance, along with relevant experiment's constantly deepening, need the test piece of multiple shape and size, the circular and square test piece of fixed standard can only be fixed to most two terminal surface stone grinder test piece fixing device in laboratory, can't satisfy the experiment very well to the diversified demand of test piece. For example, a double-end-face grinding machine disclosed in patent CN201820126235.9 cannot fix a test piece having a triangular prism shape or the like more conveniently. Therefore, a test piece clamp with strong adaptability is needed to be matched with a double-end-face grinding machine to process a test piece.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a bi-polar face stone mill test piece anchor clamps of adjustable shape and size to solve the problem that laboratory bi-polar face stone mill anchor clamps can't well satisfy the experiment to the diversified demand of test piece.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides a bi-polar face stone mill test piece anchor clamps of adjustable shape and size comprises square steel sheet barrel, drive bolt, transmission piece, fastening bolt, pressure-bearing plate groove, miniature bearing, nut, screw hole and backup pad groove, its characterized in that: the square steel plate cylinder body is open at two ends, a supporting plate groove is formed in the bottom surface inside the steel plate cylinder body, a threaded hole is formed in each of the other three surfaces, the transmission bolt is matched with the threaded hole, a miniature bearing is arranged at one end of the transmission bolt, the miniature bearing is fixedly connected with a transmission block, and the transmission block is connected with the pressure-bearing plate groove through a fastening bolt and a nut.
As a further technical scheme of the utility model, the transmission bolt is connected with the transmission block through the miniature bearing, and the transmission bolt rotates around the threaded hole to realize advancing and retreating, thereby controlling the advancing and retreating of the pressure-bearing plate groove; the transmission block is connected with the pressure-bearing plate groove through the fastening bolt, the pressure-bearing plate groove can rotate around the fastening bolt when the fastening bolt and the nut are not screwed, the pressure-bearing plate groove and the transmission block can be fastened when the fastening bolt and the nut are screwed, and the pressure-bearing plate groove cannot rotate around the fastening bolt.
As a further technical scheme of the utility model, be equipped with three pressure-bearing plate groove and a backup pad groove in the steel sheet barrel, be equipped with half arc recess on pressure-bearing plate groove and the backup pad groove, pressure-bearing plate groove and backup pad groove mutually support and can contact the test piece surface of different shapes and size, exert pressure, reach the effect of fixed test piece.
Has the advantages that:
compared with the prior art, the utility model relates to a rationally, simple structure can fix the test piece of different shapes and size well, satisfies the experiment to the diversified demand of test piece, and supports fixed test piece through pressure-bearing plate groove and backup pad groove, can not appear test piece stress concentration and lead to the phenomenon that the test piece destroys.
