Embodiment Construction

[0038] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0039] Such as Figure 1-7 A kind of vehicle body side surface anti-concave rigidity test stand of the present invention shown, comprises underframe 8 and vertical frame 1 and column 4 that are vertical to underframe and is fixedly connected with underframe and is arranged in parallel with each other; This structure is stable and reliable .

[0040] The two symmetrical mullions of the vertical frame are respectively connected with the beam mounting plate 3; the position of the beam mounting plate relative to the vertical frame can be adjusted up and down; the mounting position of the beam mounting plate can be adjusted along the Z direction of the vertical frame, and then screw The nut is fixed to realize the Z-direction adjustment and locking function of the test head.

[0041] The two ends of the horizontal beam 2 are connected to the vertical frame 1 thr...

Abstract

The invention provides a rack for testing the anti-sinking rigidity of the side surface of a vehicle body. The rack comprises a chassis, and a vertical frame and an upright post which are fixedly connected with the chassis, wherein transverse beam mounting plates are connected with the vertical frame; two ends of a transverse beam are connected with the vertical frame through the transverse beam mounting plates; an actuator mounting seat is connected with the transverse beam in manner of adjusting the relative position; the actuator mounting seat comprises a fixing seat, a movable seat and a hinge pin; the fixing seat is fixedly connected with the transverse beam; the fixing seat is hinged with one end of the movable seat and can be fixedly connected with the movable seat; the other end of the movable seat is fixedly connected with an actuator; the actuator is connected with a test head; a force sensor is arranged between the test head and the actuator; and a transverse beam transformation displacement sensor is arranged between the upright post and the transverse beam and is used for testing the deformation of the transverse beam during a rigidity test. The rack is simple in structure, easy to operate, high in adaptability and low in cost, and can effectively test the anti-sinking rigidity of the side surface of the vehicle body.

Description

technical field [0001] The invention relates to the field of mechanical testing of automobile manufacturing, in particular to a test bench for anti-concave stiffness of the side surface of a vehicle body. Background technique [0002] The anti-concave stiffness of the body surface is a performance parameter of the anti-deformation of the body after compression. Because the curvature of the side surface of the body is relatively complex, and it is vertical, there are high requirements for the adjustment and locking of the test head of the stiffness test bench. At present, the stiffness test bench we come into contact with can only test the stiffness of the horizontal surface. Contents of the invention [0003] The present invention is completed in order to solve the deficiencies in the prior art. The purpose of the present invention is to provide a test bench for the anti-concave stiffness of the side surface of the vehicle body, which has a simple structure, easy operatio...
