Description
Technical field
The present invention relates to durability of product energy detection technique field, particularly a kind of durability test apparatus for protection shield of electric circular saw that is used to detect the protection shield of electric circular saw endurance quality.
Background technology
The protective cover of electric circular saw is as a vitals of electric tool product, and protective cover needs the repeated open closure in the course of work, and its security performance is great to the security performance influence of electric tool complete machine.According to domestic and international standard, the protective cover of electric circular saw should be able to stand fatigue life test 50000 times.Yet the test for the protective cover endurance quality lacks a kind of reliable detection test unit all the time.So far, also there is not pertinent literature to set forth the effective detection test unit of a cover and carries out the test of protection shield of electric circular saw endurance quality.
Summary of the invention
The objective of the invention is at present shortage a kind of for protection shield of electric circular saw, particularly the protective cover of hand-held electric circular saw carries out the test unit of endurance quality test, the test unit of the protective cover endurance quality test of a kind of protection shield of electric circular saw that is used for, particularly hand-held electric circular saw is provided.
The technical solution used in the present invention is finished in the following way: a kind of durability test apparatus for protection shield of electric circular saw, it comprises test platform, motor, gearing, collision block and switch board, wherein, test platform is made up of frame, panel and anchor clamps, panel is fixed on frame top, anchor clamps are fixed on the panel, have the in-line opening on panel; Motor is fixed on the frame; Gearing is made up of speed reduction unit, belt pulley, bearing seat, horizontal train, chain and belt, the output terminal and the belt pulley of speed reduction unit pass through gearing mesh, belt pulley is connected by belt with horizontal train, chain be positioned at in-line opening on the panel under, chain matches with horizontal train, horizontal train is contained on the bearing seat, and bearing seat is fixed on the frame, and the output shaft of motor is connected with the input end of speed reduction unit; Collision block is contained on the chain, and the collision block epimere passes the in-line opening vertically upward.
In above-mentioned durability test apparatus for protection shield of electric circular saw, motor adopts variable-frequency motor.
In above-mentioned durability test apparatus for protection shield of electric circular saw, switch board is fixed on the frame.
Because the present invention can simulate the ruuning situation of guard shield when normal the use, makes method of testing can satisfy the requirement of testing standard to method of testing, thereby has guaranteed the reliability of guard shield durability test.
In use; the speed of motor can be regulated by control system; can regulate the speed that is installed in collision block on the chain by adjusting rotating speed of motor; realize scalable control guard shield reciprocal time thereby reach; test rate is adjustable continuously; control system is provided with rotation-clogging protection and warning function, can eliminate the hidden danger that variable-frequency motor is burnt in process of the test, and control system also has data storage function in addition.
