Description
Technical field
The present invention relates to a kind of electric tool test unit, particularly a kind of testing bench for stalling torque of electric tool that is used to measure the static stalling torque of electric tool.
Background technology
According to the safety standard requirement of electric tool, the stalling torque in the time of need being in the stall state to motor carries out just measuring.Existing test method is: load onto chuck at the electric tool output shaft, the rigid lever that connects the certain-length horizontal positioned by chuck, by last switch, the other end pressure of lever is beaten at electronic scales or is pulled down dynamometer, read static impulsive force, thereby utilize lever principle to calculate static stalling torque.Utilizing this test method shortcoming is that dynamometer is easy to generate shake more greatly owing to impact endurance test shock when the electric tool running-up test, is difficult to read the size of transient force, influences the test data accuracy; And rigid lever is can bend under the bigger situation of stalling torque at powerful instrument, and the arm of force is changed, and causes measuring error.In addition, existing locked rotor test is artificial actuating switch, and high-power instrument anchor clamps when test fly out easily, have bigger potential safety hazard.
Summary of the invention
The objective of the invention is the big weak point of the existing test data error of method at the static stalling torque of existing measurement electric tool, a kind of static stalling torque that can directly measure motor is provided, can avoids the testing bench for stalling torque of electric tool of test data error.
Technical scheme of the present invention is finished in the following way: a kind of testing bench for stalling torque of electric tool, it comprises frame, machine operation platform, column, linear stepping motor, drive screw, switch actuator, tiltable clamping platform, three-dimensional working platform, static sensor and supporting base, wherein, column is fixed on the frame, the machine operation platform is contained on the column, linear stepping motor is fixed on the machine operation platform, one end and the linear stepping motor of drive screw join, and the other end and switch actuator join; Three-dimensional working platform is fixed on the frame, and a side and the three-dimensional working platform hinge of tiltable clamping platform link together, and is provided with jacking gear in the middle of the tiltable clamping platform bottom surface, and tiltable clamping platform table top can form 0～20 ° of angle with three-dimensional working platform; Static sensor is fixed on the supporting base, and supporting base is fixed on the frame.
On above-mentioned testing bench for stalling torque of electric tool, the machine operation platform can move up and down and in position be fixedly clamped.
On above-mentioned testing bench for stalling torque of electric tool, being located at the middle jacking gear in tiltable clamping platform bottom surface is to adopt lifting jack.
During use, earlier electric tool is installed on the table top of tiltable clamping platform, the switch actuator is buckled on the switch of electric tool, and the measuring head of static sensor links to each other with the electric tool output shaft; Start linear stepping motor then, when electric tool stall moment, static sensor directly transfers to computing machine with the stalling torque that collects, and finishes once test, has avoided the factored moment and produce measuring error again of first dynamometry.
