Detailed Description
As shown in fig. 4, the static external load test of the solid engine requires two force bearing points for mounting and fixing the hydraulic actuator cylinder. The traditional static test platform adopts a fixed bearing point, so that the test limitation is large, and no more flexible choice is provided.
Therefore, the utility model provides a movable force bearing point test device, as shown in fig. 1 and fig. 2, the test device is a fan ring structure with thickness and size meeting the force bearing requirement; the center of the fan ring structure is provided with a bearing hole 3 matched with the hydraulic actuating cylinder; and fixing holes 1 for fixedly connecting with a test platform ray slot through bolts are arranged at two radial sides of a central bearing hole of the fan ring structure, and the center of each fixing hole and the center of the central bearing hole of the fan ring are positioned in the same radial direction of the fan ring structure.
The two side waists of the fan ring structure are provided with a plurality of circumferential sliding rail grooves 4, the groove roots of the plurality of circumferential sliding rail grooves on the same side waist of the fan ring structure are of arc structures, and the circle centers of the plurality of arcs are positioned in the same radius direction of the fan ring structure; in this embodiment, the included angle between the radial direction of the central force bearing hole of the fan ring structure and the radial direction of the center of the arc circle of the root of the circumferential slide rail groove on the side waist of the fan ring structure is an integral multiple of the included angle between the adjacent radial slots in the test platform, as shown in fig. 3.
The slide rail groove is used for being fixedly connected with the test platform ray groove through a bolt, the length of the slide rail groove meets the requirement of the moving range of the test device in radial movement on the test platform, and along with the radial movement of the test device on the test platform, the bolt position, which is fixedly connected with the test platform ray groove, in the slide rail groove can move along the slide rail groove.
