Problems solved by technology
[0002] Longitudinal polishing is a kind of processing technology for metal mechanical performance test samples, which requires polishing the samples along the force direction of the test, that is, longitudinal polishing, requiring polishing textures to be parallel to each other and along the axial direction of the sample; traditional The lathe is a rotary polishing, and its polishing lines are perpendicular to the direction of the force, which cannot meet the requirements of the sample. The quality of manual longitudinal polishing is unstable, and it is easy to be limited by the operator's technical level. And in the polishing process, it is difficult to control the polishing force applied

The invention discloses a longitudinal throwing device, which comprises a bottom plate, a first pair of guide rails fixed on the bottom plate, a second pair of guide rails and a protective cover. There is a clamping assembly, the side of the polishing assembly is provided with an automatic tensioning assembly, the bottom of the polishing assembly is provided with a first ball screw pair, and the bottom of the clamping assembly is provided with a second ball screw pair, so The bottom of the protective cover is fixedly connected with the top of the bottom plate. In the present invention, by setting the first guide rail pair and the first ball screw pair, the polishing assembly can be moved along the linear direction, thereby performing longitudinal polishing on the workpiece, and the longitudinal polishing effect is good, the lines are neat and parallel to each other, and the crossing of lines can be avoided etc., and the abrasive belt can be replaced by setting the upper abrasive belt disc and the lower abrasive belt disc, so as to ensure that the abrasive belt used to polish the workpiece is in the same state and avoid differences in polishing effects.
Description
technical field [0001] The invention relates to the technical field of polishing equipment for test samples of metal mechanical properties. Specifically, vertical throwing equipment. Background technique [0002] Longitudinal polishing belongs to a processing technology for test samples of metal mechanical properties. It is required to polish the sample along the force direction of the test, that is, longitudinal polishing. It is required that the polishing textures be parallel to each other and along the axial direction of the sample; the traditional The lathe is a rotary polishing, and its polishing lines are perpendicular to the direction of the force, which cannot meet the requirements of the sample. However, the quality of manual longitudinal polishing is unstable and is easily limited by the operator's technical level. The polishing lines are not parallel and appear to intersect each other. And in the polishing process, it is difficult to control the polishing force a...
