The middle areas of the pressing plate and the top plate are respectively provided with a first through hole 9-2 and a second through hole 7-2 used for exposing a test part of a test piece, the first through hole 9-2 and the second through hole 7-2 are rectangular holes, and the length and the width of the first through hole 9-2 and the second through hole 7-2 are preferably 125mm x 75 mm. .
In the embodiment, the two side plates 6 are preferably semicircular disc-shaped, a plurality of first fixing holes 6-1 are uniformly distributed on the two side plates 6 along the circumferential direction of the two side plates 6, the outer sides of the two side plates 6 are respectively and vertically provided with a wall plate 3, the inner side of the upper part of the wall plate 3 is provided with a rotary groove 3-2 matched with the side plates 6, the rotary groove 3-2 is provided with a second fixing hole 3-1 matched with the first fixing hole 6-1 at the same circumferential position with the side plates 6, the second fixing hole 3-1 penetrates through the wall plate 3, and the side plates 6 are embedded in the rotary grooves 3-2 and can freely rotate in the rotary grooves 3-2; the first fixing hole 6-1 and the second fixing hole 3-1 have diameters of 8 mm.
In this embodiment, the first fixing holes 6-1 are threaded holes, and are distributed in a single layer, the first fixing holes located in the front half portion (i.e., the front semicircular arc) of the side plate 6 are sequentially distributed from 0 ° to the top and at an interval of 10 °, and the first fixing holes located in the rear half portion (i.e., the rear semicircular arc) of the side plate are sequentially distributed from 5 ° to the top and at an interval of 10 °; the second fixing holes are consistent with the first fixing holes in arrangement mode.
To satisfy more inclination angles, the following method can be adopted: the first fixing holes are threaded holes which are distributed in a multilayer manner, the first fixing holes which are positioned on the outer layer and positioned on the front half part of the side plate are sequentially distributed from 0 degree to the top and at an interval of 10 degrees, and the first fixing holes which are positioned on the outer layer and positioned on the rear half part of the side plate are sequentially distributed from 5 degrees to the top and at an interval of 10 degrees; the first fixing holes in the inner layer and the first fixing holes in the outer layer are distributed in a staggered manner, and the staggered arrangement can be realized through different initial angles and interval angles in a specific mode of the staggered arrangement; the second fixing holes are consistent with the first fixing holes in arrangement mode.
According to the requirement of the impact test, an inclination angle is set, when the rotating frame rotates to a required impact angle (the second fixing hole and the first fixing hole can generate the required impact angle under different permutation and combination), two sets of first fixing holes and second fixing holes which are communicated are selected, and the fasteners are inserted in the two sets of first fixing holes and second fixing holes which are communicated so as to be fixed in the rotating frame, in the embodiment, the fasteners are bolt and nut pieces (marked as fastening bolts 4 and fastening nuts 5), and the rotating frame can be effectively prevented from rotating under the impact action through the fixation of the two sets of fasteners.
Considering that a test piece tends to slide tangentially after being inclined at a certain angle, the test piece is generally sensitive to a clamping force, and particularly, for a composite material aluminum honeycomb sandwich board formed by a composite material laminated board as a panel and an aluminum honeycomb as a core material, the core material in the middle is very weak, and if a large clamping force is applied, the test piece is damaged, so that an inaccurate test result is obtained, in this embodiment, rectangular stoppers 11 are symmetrically arranged on the bottom end surface of the pressing plate 9 in a front-back direction with respect to the first through hole 9-2, the stoppers 11 extend downwards in a direction perpendicular to the pressing plate 9, and the width of the stoppers 11 is consistent with the width of the test piece, and the stoppers in this embodiment are arranged: limiting the position of the test piece to prevent the test piece from sliding out in the tilting process; the top plate 7 is provided with a through hole 7-3 at a position corresponding to the limiting block 11, and the limiting block 11 can freely shuttle in the through hole 7-3, and the reason for this is that: for the test piece of centre gripping different thickness, the centre gripping space between clamp plate and the roof can be adjusted to first connecting piece in this embodiment, consequently needs set up the perforation at the roof to avoid interfering the removal of stopper.
In order to ensure that the impact position is kept at the central position of the test piece, after the test piece is inclined, the test piece sometimes needs to be moved back and forth to ensure that the impact position is at the central position of the test piece, therefore, in order to facilitate the translation, the present embodiment further includes a base 2 and a base 1, which are horizontally arranged from top to bottom, the base 2 is located at the bottom of the wall plate 3, the two wall plates 3 are fixed on the top end of the base 2 in a bilateral symmetry way, strip-shaped holes 2-1 extending along the front-back direction are arranged on the base 2 in a bilateral symmetry way, a connecting hole 1-1 is arranged at the position of the base 1 corresponding to the strip-shaped hole 2-1, the base 1 and the base 2 are connected through a second connecting piece which sequentially passes through the connecting hole 1-1 and the strip-shaped hole 2-1, the base 2 can move back and forth relative to the base 1 and is fixed in the moved position through the second connecting piece.
In this embodiment, the second connecting member is a bolt and nut member, the second bolt 13 sequentially penetrates through the connecting hole 1-1 and the strip-shaped hole 2-1, and the second nut 14 is located at the top end of the strip-shaped hole 2-1 and is connected with the second bolt 13 in a matching manner.
The whole clamping process of the test piece is further explained below.
Before the test, firstly, the test piece is cut into a proper size, namely, the length of the test piece is equal to the distance between the two limit blocks, the width of the test piece is equal to the width of the limit blocks, and the center position of the test piece is marked by a marking pen.
In this example, referring to ASTM D7136 for impact test of composite laminates and ASTM D7766 for impact test of composite honeycomb sandwich panels, the length and width of the test piece is recommended to be 150mm x 100mm, i.e. the spacing between two stoppers is 150mm and the width of the stoppers is 100 mm.
The first nut 12 is unscrewed and the pressure plate 9 is raised to a height at which the test piece can be placed from the side. The test piece is inserted into the test piece from the side surface along the top plate 7, and the width of the test piece 8 is just overlapped with the widths of the two limit blocks 11 to play a role in positioning. After the test piece is placed at an accurate position, the four first nuts 12 are screwed down, and clamping force is applied to the test piece to clamp the test piece. And then, determining an angle required by the impact, rotating the side plate 6 along the rotary groove of the wall plate 3, when the first fixing hole 6-1 of the side plate is superposed on the second fixing hole 3-1 of the wall plate to reach the required angle, penetrating the second bolt 4 through the first fixing hole 6-1 of the side plate and the second fixing hole 3-1 of the wall plate, and screwing the first nut 12, thereby preventing the change of the angle caused by looseness in the impact process.
Since the change of the impact angle causes the drop hammer to no longer impact the center position of the test piece, the entire jig needs to be translated back and forth along the sliding direction so that the drop hammer impacts the center position of the test piece again. For this purpose, the second nut 14 is unscrewed, the base 2 is translated along the strip-shaped hole 2-1 until the drop hammer just impacts the central position of the test piece at this impact angle, and after the central position is adjusted, the second nut 14 is tightened so as to clamp the whole clamp. After the impact test is completed, the second nut 14 is unscrewed, and the test piece is taken out. And then, determining the size of a test piece to be used in the next test and the required impact angle, and repeating the process to complete the subsequent test.
Finally, it should be noted that: the above embodiments are merely illustrative and not restrictive of the technical solutions of the present invention, and any equivalent substitutions and modifications or partial substitutions made without departing from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
