[0002] The control arm is a key load-bearing component of the chassis suspension system. Its mechanical properties, especially its impact resistance, directly affect the vehicle's driving safety. During the production and research and development of the control arm, it is necessary to conduct impact tests to simulate impact loads under actual working conditions, such as road bumps and collisions, in order to verify its structural strength and fatigue life.

[0003] However, in actual use, the impact power sources of traditional tooling, such as cylinders and hydraulic cylinders, are mostly fixed installations and can only be used to test control arms of specific sizes or models. When testing control arms of different specifications, the entire unit needs to be replaced, which is cumbersome and inefficient. In view of this, we propose a conveniently adjustable automotive control arm impact testing tooling. Utility Model Content

The slide groove 61 is formed around the outer wall of the base plate 1. The inner wall of the slide groove 61 is movably connected to the protrusion 62 and the support plate 63. The cooperation between the protrusion 62 and the support plate 63 enhances the stability of the device during sliding. The end of the protrusion 62 away from the base plate 1 is fixedly connected to the outer wall of the support plate 63. The upper surface of the base plate 1 has threaded grooves 64 on both the front and rear sides and near the edge for accommodating fixing bolts 65. The inner wall of the threaded groove 64 is threadedly connected to fixing bolts 65 for fixing the base plate 1 and the support plate 63 together. The outer wall of the fixing bolts 65 is threadedly connected to the inner wall of the support plate 63. A cylinder 66 for driving the impact head 67 to impact the control arm is installed on the upper side of the outer wall of the support plate 63. The output end of the cylinder 66 is detachably connected to a disassembly assembly 7 for easy disassembly and replacement of impact heads 67 of different shapes for impact testing of the control arm and for replacing impact heads 67 of different shapes.

[0017] In one embodiment of this utility model, the threaded groove 64 is configured as a cross shape, and the combined structure of the support plate 63 and the protrusion 62 is adapted to the shape of the threaded groove 64, thereby enhancing the sliding stability of the combined structure of the support plate 63 and the protrusion 62 against the threaded groove 64. The support plate 63 is configured as an L shape, and the threaded groove 64 is configured as multiple sets. The multiple sets of threaded grooves 64 are evenly distributed along the extension direction of the base plate 1. The disassembly assembly 7 includes side plates 71 for supporting the torsion spring 74 and the rotating shaft 72. The side plates 71 are configured as two sets, and the two sets of side plates 71 are respectively fixedly connected to the left and right sides of the outer wall of the output shaft of the cylinder 66.

[0018] In an embodiment of this utility model, a rotating shaft 72 for supporting the rotation of the swing rod 73 is fixedly connected to one side of the two sets of side plates 71. A swing rod 73 for inserting into the receiving frame 77 to prevent the knob cap 76 from rotating is fixedly connected to the outer wall of the rotating shaft 72. The swing rod 73 and the side plate 71 are elastically connected by a torsion spring 74 for continuously applying a force to the swing rod 73 to swing inward into the receiving frame 77. The output shaft of the cylinder 66 and the impact head 67 are threadedly connected by a threaded rod 75 for fixing the output shaft of the cylinder 66 and the impact head 67 together. A knob cap 76 for facilitating the operator to rotate the threaded rod 75 is fixedly connected to the upper surface of the threaded rod 75. A receiving frame 77 for accommodating the swing rod 73 is fixedly connected to the outer wall of the knob cap 76. The outer wall of the swing rod 73 is inserted into the inner wall of the receiving frame 77.

[0019] In this utility model, when in use, according to the size of the control arm of the car to be tested, the control arm is first placed on the base plate 1, the left side is initially limited by the left fixing frame 2, and the right side is placed on the right fixing frame 5; the sliding moving seat 4 is adjusted along the slide rail 3 to the corresponding position in the middle of the control arm, and the middle of the control arm is fixed by the clamping structure of the moving seat 4, such as bolt locking or buckle, to ensure that the control arm does not shake during the impact test.

[0020] According to the test requirements, such as different points of impact on the control arm, adjust the position of cylinder 66 and impact head 67, loosen the fixing bolt 65 so that the support plate 63 and protrusion 62 can slide along the slide groove 61 of the base plate 1. Using the guide of the cross-shaped threaded groove 64, the support plate 63 moves along the slide groove 61 until the impact head 67 is aligned with the target impact point of the control arm. After the adjustment is completed, tighten the fixing bolt 65 so that it is threadedly connected to the threaded groove 64 and the support plate 63 at the same time, and rigidly fix the support plate 63 and cylinder 66 to avoid position displacement during impact. At this time, impact tests can be performed on different positions of the control arm without replacing the equipment.

[0021] If it is necessary to replace the impact head 67 with different shapes such as conical, round, or spherical to simulate different impact conditions, the swing rod 73 can be moved outward first, so that it overcomes the elastic force of the torsion spring 74 and rotates around the pivot 72, disengaging from the receiving frame 77 on the outer wall of the knob cap 76. Rotate the knob cap 76 to drive the threaded rod 75 out of the internal threaded hole of the old impact head 67, remove the old impact head 67, and thread the new shaped impact head 67 through the internal threaded hole to the threaded rod 75. After tightening, release the swing rod 73. Under the action of the return elastic force of the torsion spring 74, the swing rod 73 automatically inserts into the receiving frame 77, restricting the accidental rotation of the knob cap 76 and ensuring that the impact head 67 is securely connected.

[0022] After the control arm is fixed, the impact position is adjusted, and the impact head 67 is installed, the cylinder 66 is started. The output end of the cylinder 66 pushes the impact head 67 to quickly impact the target position of the control arm in a preset direction, simulating the impact load under actual working conditions.

[0023] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
