DETAILED DESCRIPTION

[0031] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0033] For example, see Figure 1 to Figure 3In an embodiment of the present invention, an automobile component strength testing device includes a bottom mounting plate 1, one side of the bottom mounting plate 1 is a plane, and the other side of the bottom mounting plate 1 is a triangular slope. Two groups of bottom support frames 5 are arranged on the plane side of the bottom mounting plate 1, and there is a height difference between the two groups of bottom support frames 5. It also includes: a linkage strength testing mechanism, which is arranged on the triangular slope side of the bottom mounting plate 1, and the linkage strength testing mechanism includes a simulated loading impact module and an instantaneous passive impact module. The bottom mounting plate 1 is provided with a semi-enclosed cover 2 facing the triangular slope side, and a rotating cover plate 4 is rotatably arranged at one end of the semi-enclosed cover 2, and two groups of windows 3 are symmetrically arranged on the semi-enclosed cover 2.

[0034] The automobile parts that need strength testing are loaded onto the simulated loading impact module, and the simulated loading impact module is moved and impacted. The instantaneous passive impact module realizes uniform impact on the loaded automobile parts when impacting, thereby realizing strength testing of the automobile parts; Since there is a height difference between the two groups of bottom support frames 5, the curved or spherical surface of the magnetic impact part after impact can converge in one direction along the slope of the triangular slope and the inclined bottom mounting plate 1, which is convenient for the recovery of the magnetic impact part.

[0035] Example 2, based on Example 1, please refer to Figures 1 to 8 In the embodiment of the present invention, the simulated loading impact module includes an M-shaped guide mounting cylinder 6, one side of the M-shaped guide mounting cylinder 6 is fixed to the triangular slope side of the bottom mounting plate 1 through a plurality of connecting mounting frames 48, two sets of directional guide rails 47 are symmetrically arranged on the M-shaped guide mounting cylinder 6, a V-shaped sliding mounting plate 28 is arranged on the side of the M-shaped guide mounting cylinder 6 facing away from the bottom mounting plate 1, and the V-shaped sliding mounting plate 28 is provided with a directional guide sleeve 36 in conjunction with the directional guide rail 47, and the other end of the semi-enclosed cover 2 is flush with the right half of the M-shaped guide mounting cylinder 6; The V-shaped sliding mounting plate 28 is horizontally penetrated with an adjustment mounting hole 34, an adjustment impact column 27 is matched with the adjustment impact column 27, an impact piece 35 is provided at the outer end of the adjustment impact column 27, and the V-shaped sliding mounting plate 28 is matched with the adjustment mounting hole 34 to be provided with a plurality of locking studs 37; Two sets of transmission tripods 7 are symmetrically arranged above the bottom mounting plates 1 at both ends of the M-shaped guide mounting cylinder 6, a driving winding wheel 30 is rotatably arranged between one corner of the transmission tripod 7 and the bottom mounting plate 1, and guide wheels 29 are rotatably arranged between the other two corners of the transmission tripod 7 and the bottom mounting plate 1, and two sets of traction wires 31 extend from the driving winding wheel 30, and the two sets of traction wires 31 are respectively passed around the guide wheels 29 and connected to the directional guide sleeves 36; A plurality of air pumps 8 are disposed at one end of the M-shaped guide installation cylinder 6 , and the air pumps 8 are connected to the interior of the M-shaped guide installation cylinder 6 . A plurality of air holes 46 are evenly disposed on the cylinder wall of the M-shaped guide installation cylinder 6 facing the V-shaped sliding installation plate 28 .

[0036] As the driving winding wheel 30 at one end releases the wire and the driving winding wheel 30 at the other end reels the wire, the traction wire 31, under the action of the guide wheel 29, causes the V-shaped sliding mounting plate 28 to move under the guidance of the directional guide sleeve 36 and the directional guide rail 47. First, the V-shaped sliding mounting plate 28 is moved outside the semi-enclosed cover 2. At this time, the automobile parts to be tested are installed on the disc-shaped loading cylinder 16. Then, the driving winding wheels 30 at both ends are reversely started, and the two sets of driving winding wheels 30 rotate at high speed, so that the traction wire 31 pulls the V-shaped sliding mounting plate 28 to move in height on the M-shaped guide mounting cylinder 6 until the adjustment impact column 27 and the impact sheet 35 thereon contact the instantaneous passive impact module and transfer kinetic energy to it. During the movement of the V-shaped sliding mounting plate 28, the air pump 8 continuously guides the air into the M-shaped guide mounting cylinder 6, so that the air pressure in the M-shaped guide mounting cylinder 6 increases and is discharged from each air hole 46, so that the V-shaped sliding mounting plate 28 generates an air cushion on the surface of the M-shaped guide mounting cylinder 6, reducing the friction force, achieving acceleration to a higher speed in a shorter moving distance, and improving the range of strength detection; By adjusting the tightness of the locking stud 37 to adjust the length of the impact column 27 in the adjusting mounting hole 34, the length of the impact column 27 extending out of the adjusting mounting hole 34 can be adjusted, the impact distance can be adjusted, and different impact intervals can be adjusted, further improving the range of strength detection.

[0037] Example 3, based on Example 1, please refer to Figure 3 to Figure 8 In the embodiment of the present invention, a damping steering platform 11 is provided on the side of the V-shaped sliding mounting plate 28 away from the bottom mounting plate 1, a steering mounting column 10 is provided on the damping steering platform 11, a connecting mounting cylinder 14 is provided at the outer end of the steering mounting column 10, one end of the connecting mounting cylinder 14 is connected to a disc-shaped loading cylinder 16, and the other end of the connecting mounting cylinder 14 is connected to a pressure regulating mounting cylinder 13, a wireless air pressure sensor 12 is provided at the outer end of the pressure regulating mounting cylinder 13, and a pressure regulating pump 15 is provided on the cylinder wall of the pressure regulating mounting cylinder 13; A plurality of quick loading units are evenly arranged on one side of the disc-shaped loading cylinder 16, and the quick loading units include a pneumatic telescopic column 38 connected to the disc-shaped loading cylinder 16, and the outer end of the pneumatic telescopic column 38 is provided with a telescopic guide column 50 through a spring column 49, and the outer end of the telescopic guide column 50 is provided with a dome mounting disk 51, and a plurality of deformation rotating sheets 52 are arranged at equal angles on the dome mounting disk 51, and one end of the deformation rotating sheet 52 is rotatably connected to the dome mounting disk 51 through a reset shaft 9.

[0038] The installation of automobile parts is specifically as follows: the V-shaped sliding mounting plate 28 is moved outside the semi-enclosed cover 2, and the damping steering platform 11 is used to make the steering mounting column 10, the connecting mounting cylinder 14, the disc-shaped loading cylinder 16, and the adjusting mounting cylinder turn and shift, so as to facilitate the installation of automobile parts; According to the size of the automobile parts, the number of automobile parts to be tested at a time is selected, and the automobile parts move toward the disc-shaped loading cylinder 16, and the edge of the automobile parts contacts and passes through the round bottom mounting plate and the deformable rotating piece 52. Due to the deformation of the deformable rotating piece 52, the edge of the automobile parts can be well reversely engaged, and the reverse engagement of the deformable rotating pieces 52 on several fast loading units completes the rapid installation of the automobile parts. In this process, the spring column 49 causes the telescopic guide column 50 to deflect and telescope during the installation process, so that the automobile parts move to the other end of the deformable rotating piece 52 to complete the installation; At the same time, the pressure regulating pump 15 can adjust the air pressure in the connecting installation cylinder 14, the disc-shaped loading cylinder 16, and the adjusting installation cylinder, so that the length of the pneumatic telescopic column 38 can be adjusted to adapt to the installation of automobile parts with different thicknesses; After the impact test is completed, the automobile parts will be deformed to varying degrees. At this time, the V-shaped sliding mounting plate 28 is continued to be moved until it leaves the range of the semi-enclosed cover 2, and then the damping turning platform 11 is used to make the disc-shaped loading cylinder 16 face outward. The external extrusion equipment pushes the corresponding automobile parts one by one and maintains them for a period of time. Since the dome mounting plate 51 on the quick loading unit covered by the automobile parts in the initial state abuts against the automobile parts, the dome mounting plate 51 at the deformed part of the automobile parts is squeezed. At this time, the telescopic guide column 50 and the spring column 49 are squeezed synchronously, and the pneumatic telescopic column 38 is partially squeezed into the disc-shaped loading cylinder 16. At this time, the wireless air pressure sensor 12 records the change value of the pressure before and after the extrusion. The larger the change value, the greater the deformation, and the relatively worse the strength of the automobile parts. On the contrary, the smaller the change value, the smaller the deformation, and the relatively higher the strength of the automobile parts. After completing a set of tests, the automobile parts are removed. Under the action of external force, the edges of the automobile parts move outward, causing the spring column 49 to deflect and extend until the deformation rotating piece 52 rotates, completing the removal of the automobile parts, and repeating the above steps to perform the next set of strength tests.

[0040] When the regulating impact is inserted into the regulating impact cylinder 26 along with the V-shaped sliding mounting plate 28 moving at high speed, until the impact piece 35 on the regulating impact contacts and impacts the impact piston 45, the impact piston 45 moves synchronously with the reset piston 43 through the starting guide column 44, squeezing the reset cylinder 23, so that the pressure on one side of the reset piston 43 increases instantly, and the pressurized gas is introduced into the counter-pressure cylinder 19 through the telescopic guide tube 20, and the air pressure on one side of the counter-pressure piston 42 also increases instantly, squeezing the counter-pressure piston 42 to slide at high speed in the counter-pressure cylinder 19, so that the counter-pressure guide column 41 together with the quick-release mounting plate 32 and the counter-pressure plate 17 installed thereon move toward the disc-shaped loading cylinder 16 at high speed, and when the counter-pressure piston 42 is limited or the forces on both sides of the counter-pressure piston 42 are offset, the magnetic impact part pre-installed on the counter-pressure plate 17 flies toward the disc-shaped loading cylinder 16 and the automobile parts thereon at high speed under inertia until a collision occurs; After completing one impact, the reset piston 43 is reset under the action of the reset elastic member 40, and the impact piston 45 and the counter piston 42 are reset under the action of atmospheric pressure; When a test is completed, the steering support column 22 is rotated together with the impact cylinder 19 through the axial rotating table 21 until the impact disk 17 faces the rotating cover 4, the rotating cover 4 is opened, and the quick-release mounting disk 32 is used to cooperate with the thread 18 for quick disassembly, and then the impact disk 17 loaded with the magnetic impact part (which can be made of magnetic material or made of magnetic material wrapped in a rubber layer) is reinstalled through the cooperation of the thread 18 and the quick-release mounting disk 32, and then the impact disk 17 is again facing the disc-shaped loading tube 16, and the rotating cover 4 is closed, waiting for the next test.
