Detailed description of the invention
See accompanying drawing:
The test stationary fixture of plates of automobile class formation part, comprise support 1, the left side of support 1 is provided with hydraulic cylinder 2, the upper end installed in front of support 1 has lower chuck assembly 3, hinged on rear side of the upper end of support 1 the upper grip assembly 4 matched with lower chuck assembly 3 is installed, upper grip assembly 4 and the hinged installation in hydraulic cylinder 2 piston rod end, the right side of support 1 is provided with auxiliary support assemblies 5.
Support 1 is the reinforcement gusset 1-2 transverse plate of L-type support 1-1, L-type support 1-1 and longitudinal plate adjacent wall being fixed with dihedral, and the lateral wall of L-type support is provided with gripper shoe 1-3.
