Low-temperature falling ball impact testing machine

Abstract

According to a low-temperature falling ball impact testing machine, a placing part comprises an experiment table of a disc structure, and a plurality of sample seats arranged around the circle centerare arranged on the experiment table. The impact part comprises a fixed plate mounted at the upper end of the freezing box, and an impact column and a supporting column are arranged on the fixed plate. A lifting motor table is fixedly arranged at the top ends of the impact column and the supporting column, a lifting motor is arranged on the lifting motor table, a rotating shaft of the lifting motor is horizontally arranged, and two driven wheels parallel to the rotating shaft of the lifting motor are arranged on the two sides of the rotating shaft of the lifting motor. The impact column and the supporting column are both hollow and are of an up-down penetrating structure, and a traction rope is arranged in the supporting column. An electromagnet and a steel ball are arranged in the impactcolumn, and a placing hole for placing the steel ball is formed in the impact column. The traction rope bypasses the driven wheel and a rotating shaft of the lifting motor to be connected with the upper end of the electromagnet. A punched hole for communicating the fixed plate with the upper wall of the freezing box is formed in the lower end of the fixed plate, and is over against the upper end of the sample seat.

Description

technical field [0001] The invention relates to the field of testing equipment, in particular to a low-temperature falling ball impact testing machine. Background technique [0002] In the current traditional material impact resistance testing equipment, in order to meet the low temperature environment testing, the equipment is generally placed in an environmental chamber as a whole. Not only does it occupy a larger area, but the production cost is also correspondingly higher. Contents of the invention [0003] In order to overcome the disadvantages of the above-mentioned situation, the present invention aims to provide a technical solution capable of solving the above-mentioned problems. [0004] Low-temperature falling ball impact testing machine, including: freezer and experimental device; [0005] The experimental device consists of an impact part and a placement part; [0006] The placement part includes: a disc-structured test bench, on which there are several sam...
