Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1, the impact fixture disclosed by the utility model comprises a base 1, two sliding plates 2, a plurality of bolts 3, two fixtures 4, two mortise and tenon joints 5 and a variable angle assembly 6, wherein the base 1 is in a cuboid shape, a boss structure is arranged at the center of the bottom of the base 1 and is used as an impact groove, and the boss structure comprises a boss 12 and a groove 13. The sliding plates 2 are in a Z-shaped cuboid plate shape, and the two sliding plates 2 are symmetrically arranged at two ends of the base 1 in a sliding mode through the central axis of the impact groove. The slide plates 2 are driven so that the slide plates 2 approach each other to clamp a test piece placed between the slide plates 2, and the fixation of the test piece is achieved.
A row of bolt holes 14 are formed in the two side faces of the base 1, the base 1 is clamped with the sliding plates 2 through the clamp 4 along the width direction of the base, the boss 12 is used as an impact groove to abut against the lower portions of the two sliding plates, the impact groove forms an impact cavity of a test piece impact test on one hand, and on the other hand, a tester can take out a test piece from the impact groove conveniently.
Referring to fig. 1 and 2, through grooves 41 are formed in both side surfaces of the jig 4 in the thickness direction of the sliding plate, and hexagon socket head bolts are disposed in the through grooves 41, and the diameter of the hexagon socket head bolts is smaller than the width of the through grooves 41. The sliding plate is provided with a threaded hole matched with the inner hexagon bolt, an elastic gasket is arranged between the inner hexagon bolt and the sliding plate 2, and the diameter of the elastic gasket is larger than the width of the through groove 41.
