System for testing load durability of handheld electric tool and special test rack thereof

Abstract

The invention discloses a system for testing the load durability of a handheld electric tool. The system comprises a control system, an electric drill load durability multi-purpose test rack, an angle grinder load durability multi-purpose test rack and a cooling system, and is characterized in that: the control system comprises a test circuit, a control circuit and a display; the electric drill load durability multi-purpose test rack comprises a loading device, a working platform test sample fixing mechanism and a stand; the working platform test sample fixing mechanism comprises an experimental platform, a clamping device base, a lower V-shaped pressure head, a clamping device upright board, a pressing clamp, a pair of clamping supporting bases, a right clamping support, a left clamping support, a pair of first fastening handles, a second fastening handle, a connecting rod and an upper V-shaped pressure head; and the cooling system is connected with the loading device of the electricdrill load durability multi-purpose test rack. The system for testing the load durability of the handheld electric tool has high test efficiency and high measurement precision, occupies small space, and is low in manufacturing cost.

Description

technical field [0001] The invention relates to a test device for a hand-held electric tool, in particular to a load endurance test system for a hand-held electric tool and a special test frame thereof. Background technique [0002] Hand-held power tools mainly include electric drills and angle grinders. National standards have specific requirements for no-load, load, downtime and load size of hand-held power tools. At present, the tests of the two types of products are carried out in different test systems, the utilization rate of the equipment is not high, and it takes up a lot of space. In addition, due to the wide variety of hand-held electric tools, such as electric drill tools include electric hammers, ordinary electric drills, impact drills and electric picks, and angle grinding tools include grinders, polishers and sanders, etc., while existing The test frame in the test system uses conventional universal fixtures to fix the tested samples, and usually needs to add ...
