Description

Technical Field

[0001] This utility model relates to the technical field of anti-collision beam testing devices, and in particular to an anti-collision beam testing device. Background Technology

[0002] Anti-collision beams are important safety components of automobiles. Installed at the front and rear of the vehicle, they are generally made of high-strength steel or aluminum alloy and are mostly crossbeam structures. The anti-collision beam plays a crucial role in preventing colliding objects from penetrating the vehicle body during a collision, thereby protecting critical vehicle components and the safety of the occupants. Because of the important protective role of anti-collision beams, they must undergo compression resistance testing. Only anti-collision beams that have passed rigorous testing can provide strong protection for driving safety.

[0003] In the process of testing the compressive strength of the crash beam, fixing the crash beam is a key step. The common fixing method is to use the mounting holes on the energy-absorbing box mounting plate with bolts and nuts. However, this method involves many repetitive operations and is cumbersome. A lot of time is spent on tightening the bolts and nuts in each test, which reduces the efficiency of the crash beam testing work. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figure 1-4 The device shown is a crash beam testing device, which includes a testing machine body 1 and a crash beam body 2. The testing machine body 1 consists of a testing machine main body 101 and two I-shaped mounting bases 102. The crash beam body 2 consists of a crash beam body 201, an energy absorption box 202 and a mounting plate 203. A quick-setting mechanism 3 is symmetrically provided below the crash beam body 201. The quick-setting mechanism 3 is used to quickly complete the fixing steps of the crash beam and improve the efficiency of the crash beam testing work.

[0026] The quick-setting mechanism 3 includes a T-shaped cavity, which is located inside the I-shaped mounting base 102. A lifting plate 301 is located within the T-shaped cavity. Multiple limiting sliding holes are arranged in a rectangular array on the bottom of the inner wall of the T-shaped cavity. Limiting sliding rods 306 are slidably connected to the inner cavities of these limiting sliding holes. The limiting sliding rods 306 and the limiting sliding holes restrict the movement trajectory of the lifting plate 301, improving the stability of its vertical movement. The multiple limiting sliding rods 306 are fixedly connected to the bottom of the lifting plate 301. L-shaped pressing plates 302 are symmetrically arranged on the top of the lifting plate 301. The bottom of each L-shaped pressing plate 302 is fixedly connected to the top of the lifting plate 301. Rubber pads 4 are fixedly connected to the bottom of the L-shaped pressing plates 302, serving to buffer and increase friction. The bottom of the rubber pads 4 has evenly distributed friction patterns. A circular hole is provided at the top, and a threaded rod 303 is provided in the inner cavity of the circular hole. The threaded rod 303 is fixedly connected to the top of the inner wall of the T-shaped cavity. A hexagonal nut 304 is fitted on the outer wall of the threaded rod 303. The inner wall of the hexagonal nut 304 is threadedly connected to the outer wall of the threaded rod 303. The hexagonal nut 304 rotates clockwise on the threaded rod 303 and moves downward along the threaded rod 303. The hexagonal nut 304 rotates counterclockwise on the threaded rod 303 and moves upward along the threaded rod 303. A circular washer 5 is provided below the hexagonal nut 304. The circular washer 5 serves to protect and reduce friction. The circular washer 5 is movably fitted on the outside of the threaded rod 303. A reset assembly 305 is provided below the hexagonal nut 304. The reset assembly 305 is used to drive the lifting plate 301 and the L-shaped pressing plate 302 to automatically perform a reset movement, which improves the convenience of operation.

[0027] The reset assembly 305 includes a cylindrical hole, an outer sleeve 3051 is movably fitted into the inner cavity of the cylindrical hole, the outer wall of the outer sleeve 3051 is fixedly connected to the inner wall of the circular hole, and a reset spring 3052 is fixedly connected to the bottom of the outer sleeve 3051. The reset spring 3052 can undergo elastic deformation, thereby driving the outer sleeve 3051 to perform a reset movement. A threaded hole is opened at the bottom of the inner wall of the cylindrical hole, and a support circular plate 3053 is threadedly connected to the inner wall of the threaded hole. The support circular plate 3053, which rotates counterclockwise in the threaded hole, will gradually move away from the outer sleeve 3051 and eventually completely disengage from the threaded hole. The threaded hole and the support circular plate 3053 provide convenience for the operator to replace the reset spring 3052. The reset spring 3052 is fixedly connected to the top of the support circular plate 3053, and a strip-shaped auxiliary groove is opened at the bottom of the support circular plate 3053. The strip-shaped auxiliary groove makes it easy for the operator to use a flathead screwdriver to drive the support circular plate 3053 to rotate.

[0028] Working principle of this utility model:

[0029] When conducting the compressive strength test on the anti-collision beam, the anti-collision beam is first transported onto the two I-shaped mounting seats 102 of the compressive strength testing machine with the two mounting plates 203 facing downwards. During this process, the mounting plate 203 is inserted from one side of the L-shaped pressing plate 302 between the L-shaped pressing plate 302 and the I-shaped mounting seat 102. After the above steps are completed, a wrench is inserted into the T-shaped cavity and rotates the hexagonal nut 304 clockwise. The clockwise rotation of the hexagonal nut 304 on the threaded rod 303 will drive... The lifting plate 301 and the L-shaped pressing plate 302 move vertically downwards. When the L-shaped pressing plate 302 cooperates with the I-shaped mounting base 102 to complete the pressing work of the mounting plate 203, the fixing work of the anti-collision beam to be tested is completed. After the wrench is removed from the T-shaped cavity, the test machine can be turned on to carry out the compressive strength test of the anti-collision beam. The fixing steps of the anti-collision beam are quickly completed by only turning two hexagonal nuts 304, which simplifies the operation and improves the efficiency of the anti-collision beam test.
