Abstract

The invention provides a drop hammer type multi-angle impact clamp with a stable impact position. Two side plates of a rotating frame are of semi-disc shapes respectively, each side plate is providedwith first fixing holes which are evenly distributed in the circumferential direction, wall plates are vertically arranged in the outer sides of the two side plates respectively, the upper inner sideof each wall plate is provided with a rotating groove adapted to the corresponding side plate, each rotating groove is provided with second fixing holes cooperated with the first fixing holes at the same circumferential positions as the side plate, each side plate is embedded into the corresponding rotating groove and can rotate freely in the rotating groove, and when the rotating frame is rotatedto a required impact angle, at least two communicated first and second fixing hole groups are selected from the outer side of the wall plate, and fastening pieces are inserted into the selected fixing holes to fix the rotating frame. The multi-angle impact clamp can realize multi-angle adjustment, ensure the stability of the impact angle, and avoid damage of clamping on a test piece.

Description

technical field [0001] The invention belongs to the technical field of drop hammer impact fixtures, in particular to a drop hammer multi-angle impact fixture with stable impact positions. Background technique [0002] With the improvement of composite material technology, various structural parts made of composite materials have increased significantly. However, related panels made of composite materials, such as composite laminates, fiber metal laminates, and composite honeycomb sandwich panels constructed of composite materials as face sheets, are particularly susceptible to low-velocity impact loads. In order to evaluate the impact resistance of related plates made of composite materials, a large number of related drop weight impact testing machines have emerged as the times require. However, after investigation, it is found that the fixtures of various drop weight impact testing machines can only clamp the specimen for vertical and positive impact, and cannot cooperate ...
