Clamping piece polishing device

Abstract

The invention provides a clamping piece polishing device. The clamping piece polishing device comprises a clamping piece mounting base and a polishing cover plate, wherein the bottom face of the base is rectangular; a large groove which is concave is formed in the top of the base; the large groove is composed of two slopes which descended from the edge of the base along the middle part, and a cubic small groove arranged between the two slopes; a baffling sheet is arranged on a higher side part of each slope and a clamping piece positioning piece is arranged above a lower side of each slope; the clamping piece positioning pieces and the two ends of the baffling sheets are connected by screw rods; the polishing cover plate is composed of a cover plate body, polishing abrasive paper and an abrasive paper positioning strip; and the abrasive paper positioning strip is used for fixing abrasive paper on the cover plate body so that the abrasive paper has a flat polishing face. With the adoption of the structure, a polishing position can meet the requirements and accurate testing data are obtained; a plurality of clamping pieces can be polished by one time of operation so that the working efficiency can be improved.

Description

technical field [0001] The invention belongs to the field of clip performance testing, and in particular relates to an auxiliary device for grinding a clip when testing the hardness of the clip. Background technique [0002] Anchors are widely used in projects such as highways, railways and municipal bridges, housing construction, hydraulic construction, TV towers, large containers, rock anchors and ground anchors. The large difference between the hardness values ​​obtained from the test on the clip makes the test results inaccurate. In the traditional test method, the clips are polished one by one by hand. Most of the polished surfaces are not on the small plane at the position of the generatrix at the highest point of the clip, but on the left and right arcs. However, the arcs are subjected to The test data obtained at the specified pressure of the punch is smaller than the true value, and the test data obtained on different arc surfaces are also different, which leads to...

Problems solved by technology

[0002] Anchors are widely used in projects such as highways, railways and municipal bridges, housing construction, hydraulic construction, TV towers, large containers, rock anchors and ground anchors. The hardness value obtained from the test on the clip is quite different, which makes the test result inaccurate

In the traditional test method, the clips are polished one by one by hand. Most of the polished surfaces are not on the small plane at the position of the generatrix at the highest point of the clip, but on the left and right arcs. However, the arcs are subjected to The test data obtained at the specified pressure of the punch is smaller than the true value, and the test data obtained on different arc surfaces are also different, so the hardness value on the same clip is quite different.
