Abstract

The invention relates to an automatic friction sensitivity instrument. An oil supplier is arranged in a hydraulic tank and connected with a hydraulic cylinder which abuts against the bottom of a hydraulic jacking device; a bracket base is positioned above the hydraulic jacking device, a test sample friction device is arranged on the bracket base; an ejector rod and a sensor are arranged between the test sample friction device and the hydraulic jacking device; a transmission platform is positioned above the bracket base, an electric magnet is arranged on the transmission platform and attracts a pull rod; the pull rod is connected with a driving wheel and a drive motor and pulls the driving wheel and the drive motor to move on a motor guide holder; the drive motor drives the driving wheel and drives a driven wheel by a driving belt; the driven wheel is connected with a swing rod by a driven shaft; a heavy punch is arranged on the swing rod; a firing pin is positioned between the heavy punch and the test sample friction device so as to enable the heavy punch to strike the firing pin and the test sample friction device sequentially; and a photoelectric encoder is arranged on the driven shaft and rotates along with the driven shaft. The friction sensitivity instrument has the advantages of having high automation degree and accurate test performance, being time-saving and effort-saving, and the like.

Description

technical field [0001] The invention relates to a friction sensitivity meter, in particular to an automatic friction sensitivity meter. Background technique [0002] The friction sensitivity meter is mainly used to measure the friction sensitivity of energetic materials (solid explosives, high explosives, propellants, fireworks and firecrackers, etc.), and its working principle is: under the action of a certain positive pressure, the energetic materials pass through the detection pendulum Whether it explodes or burns when the impact makes it translate a certain displacement, so as to measure its translational friction sensitivity. [0003] The friction sensitivity meter in the prior art is usually operated manually, which has defects such as large error, low degree of automation, high labor intensity and low efficiency of the staff, and danger during the experiment process. [0004] Therefore, in order to avoid the above-mentioned technical problems, it is indeed necessary ...
