Test system for no-load and locked-rotor characteristics of handheld electric tool

Abstract

The invention discloses a test system for the no-load and locked-rotor characteristics of a handheld electric tool. The test system comprises a control system, a locked-rotor characteristic test frame and a no-load characteristic test frame, wherein the control system comprises a test circuit, a control circuit and a display; the no-load characteristic test frame comprises a machine frame and an upper platform; a pair of clamping devices with the same structures substantially is arranged on the upper platform; a speed measuring meter is arranged at the place below the upper platform, which faces an axially extending end of a test sample; and the locked-rotor characteristic test frame comprises a force measuring device, a work platform test sample fixing mechanism and a machine frame. The test system is mainly used for monitoring the working condition of the handheld electric tool, is the two-in-one specialized test equipment which can test the no-load characteristic and the locked-rotor characteristic of an electric drill, an electric hammer and the like, is the test equipment necessary for ensuring the safety of various handheld electric tools, is convenient to operate and maintain, is safe and reliable, and is high in performance. The no-load characteristic universal test frame and the locked-rotor characteristic universal test frame of the test system can quickly lock various tested handheld electric tools, so the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to a performance testing device of a hand-held electric tool, in particular to a test device for no-load and locked-rotor characteristics of a hand-held electric tool, in particular to a test system for no-load and locked-rotor characteristics of a hand-held electric tool. Background technique [0002] The no-load and stall characteristics of hand-held power tools are important performance indicators of hand-held power tools, which must meet the national standards. Usually, the two are in the no-load characteristic system and the locked-rotor characteristic system respectively, and each system needs to be equipped with a set of control system and power supply, which not only has high equipment cost, but also takes up a lot of space, which is not economical and practical. It takes more time and effort to transport the sample from one test system to another test system, so the efficiency is very low. [0003] In addition, the test ...

AI Technical Summary

Problems solved by technology

[0004] What the present invention aims to solve is that the tests of different characteristics existing in the prior art are carried out in different test systems respectively, resulting in the problem of low equipment utilization and large space occupation. It aims to provide a hand-held electric Comprehensive test system for tool no-load and stall characteristics

[0005] The present invention also needs to solve the problem of unreliable and inconvenient fixation of general sample fixtures in the prior art, and aims to provide a special universal test frame and a hand-held electric tool using the universal test frame without load and stall characteristic test system
