Abstract
A fatigue testing fixture of a rear auxiliary frame comprises a base seat, a first substrate, a second substrate, a guide substrate, a wheel disc, a third substrate and a guide rod. The first substrate comprises a first clamping head and a second clamping head arranged above the first clamping head. The second substrate comprises a third clamping head and a fourth clamping head arranged above the third clamping head. The wheel disc is arranged on the guide substrate in a hanging mode and in the longitudinal direction, and capable of swinging forth and back. One side of the wheel disc is movably connected with a loading rod. The third substrate is arranged on the base seat, and on the other side of the guide substrate. Two ends of the guide rod are capable of being movably connected with the wheel disc and the third substrate. Compared with the prior art, the fatigue testing fixture of the rear auxiliary frame has the advantages that the four clamping heads are arranged in the longitudinal direction, when the test is loaded, an air cylinder is only need to be arranged horizontally instead of being arranged perpendicularly, and therefore occupied spaces of height and land are reduced, setting requirements of the air cylinder are greatly lowered, and therefore the fatigue testing fixture of the rear auxiliary frame is beneficial for effectively controlling cost.
Description
Technical field
The present invention relates to a kind of anchor clamps, relate in particular to a kind of anchor clamps that are applied to the Rear secondary frame for vehicle torture test.Then this clamp clamps Rear secondary frame for vehicle to be tested can test its fatigability.
Background technology
The tired durable actual road test of automobile rear sub-frame is the effective way of Rear secondary frame for vehicle safety and reliability data acquisition.But because of present actual road test cycle long, cost is high, along with the competition in the automobile industry constantly aggravates, the automaker wishes can accomplish cost-effective purpose when satisfying security that the user improves day by day and reliability requirement, therefore, tired durable bench test becomes the development trend of fatigue of automobile parts test; Namely come the simulated roadway site test by indoor test, thereby reach the purpose that the test period is short, cost is low.
The Rear secondary frame for vehicle fatigue test clamper is mechanism relatively more crucial in the Rear secondary frame for vehicle testing fatigue frock, and the quality of its design directly has influence on difficulty of test and testing cost.Common back-auxiliary cycle frame structure as shown in Figure 1, comprise body 1a and be connected in spring wheel disc 2a on the body 1a, four jiaos of body 1a have four ends, be respectively end 11a, end 12a, end 13a and end 14a, the middle part of spring wheel disc 2a has volute spring installation position 21a, generally testing fatigue is carried out in three some positions of Rear secondary frame for vehicle, be respectively spring wheel disc position, driving front position 4a and rear transmission position 3a.Common Rear secondary frame for vehicle test fixture is comprised of a plurality of chucks at present, each chuck is fixed, and, Rear secondary frame for vehicle tiles basically during test, during testing fatigue, finishes by cylinder for the acting force of the spring wheel disc position, driving front position and the rear transmission position that are loaded into, like this, cylinder is vertical the setting, and cylinder is to be arranged on tall and big gantry bracing frame, cylinder knee-action in the test process.There is following deficiency in this test fixture: at first, chuck is all fixed, so a cover frock can only be tested the Rear secondary frame for vehicle of some types, range of application is narrower, for the dissimilar Rear secondary frame for vehicle of many covers, needs many cover test fixtures, therefore, cost is higher; Secondly, cylinder vertically acts on, and it is higher that gantry bracing frame need to be made, and therefore needs larger occupation of land space and accounts for high spatial, and simultaneously gantry bracing frame infusion of financial resources is larger, and the bulk testing integrated cost is higher.
Summary of the invention
Technical matters to be solved by this invention is the Rear secondary frame for vehicle fatigue test clamper that provides a kind of cylinder energy level to load for the above-mentioned state of the art.
