Abstract

The utility model relates to a fatigue machine, which mainly solves the technical problems that the existing fatigue testing machine controls reciprocating movement of a clamp disc relying on positive/negative rotation of a driving motor so as to the driving motor is easily damaged. The fatigue testing machine is characterized in that: a main output shaft is connected with a main transmission shaft through a crank-rocker mechanism. The benefits of the fatigue testing machine are as follows: a gear transmission mechanism for driving the original main output shaft is changed into the crank-rocker transmission mechanism, while, the adoption of the crank-rocker mechanism can realize the reciprocating movement of the clamp disc without needing positive/negative rotation of the driving motor; the torsion angle of the clamp disc can be adjusted through adjusting a rocker length of the crank-rocker mechanism; for the adoption of the above structure, the damage of the driving motor caused by frequent positive/negative switching of the driving motor can be effectively avoided, meanwhile, the service life of the whole machine can be effectively extended.

Description

Fatigue tester
Technical field
The utility model relates to a kind of checkout equipment, relates to a kind of fatigue tester in particular, is mainly used in the anti-fatigue performance that detects parts.
Background technology
Existing fatigue tester mainly includes drive unit, final drive shaft, main output shaft and fixing chuck, described fixedly chuck is fixed on the main output shaft, described drive unit includes drive motor, reducing gear and gear drive, described final drive shaft is connected by the gear drive synchronous interaction with main output shaft, its principle of work is to utilize the positive and negative to-and-fro movement that transfers the drive main output shaft of drive motor, detects the anti-fatigue performance of parts with this; Adopt this structure, though can reach testing goal, but because the time of anti-fatigue test is longer, drive motor then need be under long situation, frequent carry out positive anti-switching, be easy to burn drive motor like this, cause the damage of drive motor, thereby the serviceable life of having improved detection cost and equipment is shorter.
Summary of the invention
Rely on the positive and negative to-and-fro movement that transfers the control card dish of drive motor in order to solve existing fatigue tester, cause technical matterss such as drive motor is fragile; The utility model provides a kind of fatigue tester, and it is simple in structure, and is reasonable in design, can effectively solve the flimsy problem of drive motor, and can reduce corresponding cost, prolongs the serviceable life of equipment.
For solving above technical matters, the technical scheme that the utility model is taked is a kind of fatigue tester, it includes head box, drive unit, final drive shaft, main output shaft and chuck, described drive unit, final drive shaft, main output shaft and chuck are installed in the head box, described chuck is fixed on the main output shaft and places outside the head box, described final drive shaft and drive unit are connected, and described final drive shaft is connected with the main output shaft synchronous interaction; It is characterized in that linking to each other by crank and rocker mechanism between described main output shaft and the final drive shaft.
Further, described crank and rocker mechanism includes initiatively rocking arm, passive rocking arm and drive plate, and described initiatively rocking arm and passive rocking arm are hinged; Described drive plate is fixed on the final drive shaft, and described initiatively rocking arm one end off-centre is hinged on the drive plate, and described passive rocking arm is fixed on the main output shaft.
Further, all sidewalls of described chuck are provided with pointer, are provided with the one division dish in the inboard of the inboard head box of described chuck, the outside surface of this index plate be provided with graduated scale and with the coaxial setting of chuck.
Further, described pointer is provided with three groups and stationary distribution on all sidewalls of chuck.
The beneficial effects of the utility model are original main output shaft to be driven to change into by the crank rocker gear train by gear drive drive, and the employing crank and rocker mechanism, the positive and negative rotation that need not drive motor just can realize the to-and-fro movement of chuck, the windup-degree of chuck can be adjusted by the rocking bar length of regulating crank and rocker mechanism, adopt this structure not only can effectively avoid causing the damage of drive motor because of the frequent positive anti-switching of drive motor, simultaneously, also can effectively improve the serviceable life of complete machine.

Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further:
As shown in Figure 1 to Figure 3, a kind of fatigue tester of the utility model, it includes head box 1, drive unit 2, final drive shaft 3, main output shaft 4 and chuck 5, described drive unit 2, final drive shaft 3, main output shaft 4 and chuck 5 are installed in the head box 1, described drive unit 2 includes drive motor 21, gear drive reducing gear 22, described chuck 5 is fixed on the main output shaft 4 and places outside the head box 1, described final drive shaft 3 is connected with the gear drive reducing gear 22 of drive unit 2, and described final drive shaft 3 is connected with main output shaft 4 synchronous interactions; In order to solve the positive and negative to-and-fro movement that transfers control card dish 5 of existing fatigue tester dependence drive motor 22, cause technical matterss such as drive motor 21 is fragile, link to each other by crank and rocker mechanism 6 between described main output shaft 4 and the final drive shaft 3, and employing crank and rocker mechanism 6, the positive and negative rotation that need not drive motor 21 just can realize the to-and-fro movement of chuck 5, the windup-degree of chuck 5 can be adjusted by the rocking bar length of regulating crank and rocker mechanism 6, adopt this structure not only can effectively avoid causing the damage of drive motor 21 because of drive motor 21 frequent positive anti-switchings, simultaneously, also can effectively improve the serviceable life of complete machine.
In the present embodiment, described crank and rocker mechanism 6 includes initiatively rocking arm 61, passive rocking arm 62 and drive plate 63, and described initiatively rocking arm 61 is hinged with passive rocking arm 62; Described drive plate 63 is fixed on the final drive shaft 3, and described initiatively rocking arm 61 1 end off-centre are hinged on the drive plate 63, and described passive rocking arm 62 is fixed on the main output shaft 4; Adopt this structure, drive plate 63 is followed final drive shaft 3 rotations, and initiatively rocking arm 61 is hinged on the drive plate 63 owing to off-centre, when drive plate 63 rotations, the initiatively rocking arm 61 and the pin joint of passive rocking arm 62 are moved up and down, thereby realize the to-and-fro movement of main output shaft 4.
In the present embodiment, be the convenient windup-degree of regulating chuck 5, all sidewalls of described chuck 5 are provided with pointer 51, be positioned in described chuck 5 inboards and be provided with one division dish 7 on the head box 1, the outside surface of this index plate 7 be provided with graduated scale and with chuck 5 coaxial settings, adopt this structure, the graduated scale on the index plate 7 can be regulated the windup-degree of chuck 5 for reference, thereby guarantee to detect the accuracy of test.
