Vehicle body point load loading device

The utility model provides a vehicle body point load loading device which comprises a spiral loading mechanism for pressing a vehicle body covering part, the spiral loading mechanism is connected with a position adjusting mechanism for adjusting the X direction, the Y direction and the Z direction of the spiral loading mechanism, the spiral loading mechanism is connected with the position adjusting mechanism through a multi-shaft mechanical arm or a universal ball head bearing, and the universal ball head bearing is provided with a locking device. In this way, the spiral loading mechanism can rotate around the universal ball head bearing to adjust the force application angle at will, and therefore testing of vehicle body covering parts with different curved surfaces is completed. 本实用新型提供一种车身点载荷加载装置，包括对车身覆盖件进行按压的螺旋加载机构，螺旋加载机构与调节其X、Y、Z方向的位置调节机构相连，螺旋加载机构通过多轴机械臂或万向球头轴承与位置调节机构相连，万向球头轴承具有锁紧装置。这样螺旋加载机构可以通过绕万向球头轴承转动随意调节其施力角度，从而完成对不同曲面的车身覆盖件的测试。
