Problems solved by technology

However, with the continuous deepening of rock mechanics research, standard rock specimens can no longer meet the test requirements, and the traditional double-end stone grinder specimen fixing device can only fix cylindrical and cuboid specimens, but cannot meet the requirements of prismatic specimens. Requirements hindered the progress of relevant tests, through the free movement, the adjustable angle of the fixture can not only meet the fixed processing of standard rock samples, but also effectively realize the processing of samples with different cross-sectional shapes

Abstract

The invention relates to the technical field of a rock mechanical property test, specifically to a sample fixing device for a double-end-face grinding stone machine. The sample fixing device comprises a fixing frame and a clamping device. The fixing frame includes a beam plate, a stringer plate, a pedestal and a screw rod, wherein the stringer plate and the screw rod are fixed at two ends of the pedestal, one end of the beam plate is in a split mounting arrangement with the stringer plate, and the other end of the beam plate is arranged relative to the screw rod. The clamping device is arranged on the pedestal and comprises two sets of main clamps, which are symmetrically arranged at right and left sides of the clamping device and each of which includes a bearing plate, a transmission beam, a slide hinge seat, and a support rod. Through adoption of the structural arrangement, regular processing of a standard rock sample is satisfied, and samples with different cross-sectional shapes can be processed.

Description

technical field [0001] The invention relates to the technical field of rock mechanical property testing, in particular to a sample fixing device for a double-end-surface grinder. Background technique [0002] In civil engineering, mining, transportation, water conservancy, metallurgy and other industries, many geotechnical engineering projects require a large number of rock mechanical property tests. The rock blocks are recovered from the site and processed into rock specimens that meet national standards. However, with the continuous deepening of rock mechanics research, standard rock specimens can no longer meet the test requirements, and the traditional double-end stone grinder specimen fixing device can only fix cylindrical and cuboid specimens, but cannot meet the requirements of prismatic specimens. Requirements hindered the progress of relevant tests, through the free movement, the adjustable angle of the fixture can not only meet the fixed processing of standard roc...
