Specific embodiment
With reference to the accompanying drawings and detailed description, the utility model is described in further detail.
Embodiment 1: as shown in Figs. 1-5, a kind of self-piercing riveting grip device, including positioning clamping plate 2, primary clamp body clamp body 3, liter
Plate 9, clamping plate 12 and lifting stud 15 drop, and the primary clamp body clamp body 3 is stepped, and the high-end two sides of primary clamp body clamp body 3 are equipped with upwards
Primary clamp body clamp body baffle 1,3 low side face of primary clamp body clamp body are equipped with threaded hole 13, and the high low side faying surface of primary clamp body clamp body 3 is equipped with centre bore 5, main
It is equipped with primary clamp body clamp body boss 7 at the high low side ladder of clamp body 3, it is high-end above that the positioning clamping plate 2 is placed on primary clamp body clamp body 3, fixed
To positioning clamping plate boss 4 is had, positioning clamping plate 2 is convex by positioning clamping plate with primary clamp body clamp body 3 for position 2 two sides of clamping plate
Interference fit between platform 4 and primary clamp body clamp body baffle 1 is fixed test specimen lower substrate, and the lifter plate 9 is installed on primary clamp body clamp body 3
Above low side, 9 one end of lifter plate is equipped with lifter plate boss 6, and lifter plate boss 6 be slidably matched drawing with primary clamp body clamp body boss 7
It leads lifter plate 9 to move up and down, 9 two sides of lifter plate are equipped with lifter plate baffle 11 upwards, and the clamping plate 12 is placed on lifter plate 9
Face, 12 two sides of clamping plate pass through clamping plate boss 10 and lifting to clamping plate boss 10, clamping plate 12 and lifter plate 9 is had
Interference fit between plate baffle 11 is fixed test specimen upper substrate, and the lifting stud 15 is connected through a screw thread and threaded hole 13
Cooperation driving lifter plate 9 is moved up and down to limit bondline thickness.
It is equipped with limitation baffle 14 upwards it is possible to further which the 3 low side side of primary clamp body clamp body is arranged, for limiting lifting
The freedom degree of plate 9.
It is possible to further which the lifter plate boss 6 is arranged equipped with graduation mark 8, it to be used for identification coatings thickness.
It is clear opening it is possible to further which the centre bore 5 is arranged, diameter is identical as self-piercing riveting equipment die outer diameter,
And center line is overlapped when working.
The working principle of the utility model is: in use, lower substrate to be first placed in primary clamp body clamp body 3 is the upper surface of high-end to be covered
Centre bore 5, wherein a long side withstands the primary clamp body clamp body baffle 1 in the high-end left side of primary clamp body clamp body 3 to limitation lower substrate, limitation lower substrate its
In a short side withstand lifter plate boss 6, then positioning compression plate 2 is placed on lower substrate, passes through positioning clamping plate boss 4 and main folder
The interference fit of specific baffle 1 is fixed lower substrate；Rotation lifting stud 15 drives 9 uplink of lifter plate or moves down, and makes to go up and down
It is just bondline thickness required by technique that plane, which is higher by the height of plane on lower substrate, on plate 9, and numerical value can pass through scale
