An embossing connection cross positioning clamping device and a method for assembling and disassembling test pieces

Abstract

The invention discloses a stamping connection cross location clamping device and a method for assembling and disassembling test specimens, and belongs to the field of clamp design. The device comprises an X-direction connecting plate I, an X-direction connecting plate II, a baffle, a rectangular groove, an angle plate I, an angle plate II, a Y-direction connecting plate I, a Y-direction connectingplate II, a location block, a central hole, a working table, a limiting hole I, a limiting hole II, a rotating handle, a threaded rod, a sliding rod, a threaded hole I and a threaded hole II. Accordingly, the location device can cooperate with stamping and self-piercing riveting equipment and can be used for stamping connection and self-piercing riveting connection; the location device is suitable for the test specimens different in length, width and thickness; automatic centering of workpieces can be achieved without scales; the location device can ensure that the cross stamping test specimen is 90 degrees; in the test specimen clamping process, hand holding is not needed, and the operation safety is improved; the test specimens can be located and clamped rapidly and accurately, and thework efficiency and the accuracy of the experimental data are improved.

Description

technical field [0001] The invention relates to an embossing connection cross positioning clamping device and a method for assembling and disassembling test pieces, belonging to the field of fixture design. Background technique [0002] Embossing connection is a new light-weight sheet material connection technology, which is mainly used to solve the connection problem of difficult-to-weld new light-weight sheet materials. In order to achieve the effect of energy saving and emission reduction through weight reduction and efficiency increase in aerospace, high-speed train, light automobile and other manufacturing industries, the new light sheet material embossing connection technology will gradually replace spot welding technology and become the mainstream manufacturing technology of the next generation of light body-in-white. [0003] The embossing connection is under the action of the connecting mold, so that the combination of materials to be connected undergoes cold extrus...
