Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, and in particular to a strength testing device for automobile parts. Background Technology

[0002] The automobile manufacturing process produces a large number of parts. To ensure part quality, strength testing is required. This testing uses specialized strength testing equipment, but this equipment has some shortcomings and areas for improvement: 1. The common testing method uses hydraulic pressing, but parts can break and scatter during the process. Therefore, the testing facility needs to add a specialized protective mechanism to prevent debris from flying. 2. During testing, parts need to be placed correctly, but irregularly shaped parts may require a limiting mechanism to hold them in place before pressing and flipping. Therefore, we propose a strength testing device for automotive parts. Utility Model Content

[0008] By adopting the above technical solution, both the No. 1 and No. 2 protective frames are made of transparent material, which can effectively observe the detection effect and provide protection.

[0009] Preferably, the telescopic positioning rod is inserted and engaged with the nearby limiting circular hole, the first protective frame is fixedly connected to the lower inner wall of the bracket, and the hydraulic rod and the pressing plate are both located inside the first and second protective frames.

[0010] By adopting the above technical solution, the telescopic positioning rod and the limiting hole can be engaged to retract or lower the No. 2 protective frame.

[0011] Preferably, the limiting mechanism includes a rectangular platform, with rectangular slots at the upper front and upper rear ends of the rectangular platform. A motor is fixedly connected to the left inner wall of the front rectangular slot, and a screw is fixedly connected to the output end of the motor. A sliding rod is fixedly connected between the left and right inner walls of the rear rectangular slot. A limiting plate is threadedly engaged between the left and right ends of the screw and the sliding rod. Rollers are movably connected to the lower front and lower rear ends of the two sets of limiting plates through a U-shaped rod. Several sets of cleaning slots are equidistantly opened at the middle of the upper end of the rectangular platform.

[0014] By adopting the above technical solution: several sets of cleaning grooves are also opened on the worktable, and the rollers can make the sliding of the limit plate smoother.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up a testing mechanism, the connecting seat on the testing mechanism drives the lower hydraulic rod and pressing plate, which can facilitate the testing of parts. At the same time, the external first and second protective frames can effectively prevent debris from flying during testing, and the transparent material setting can facilitate the observation of the testing effect.

[0016] 2. By setting a limiting mechanism, the limiting plate on the limiting mechanism can move left and right under the drive of the motor and screw, clamping and fixing irregularly shaped parts, which facilitates subsequent strength testing of the parts.

[0022] Please see Figure 1-6This utility model provides a technical solution: A strength testing device for automotive parts includes a workbench 1, an operating panel 2 fixedly connected to the left front end of the workbench 1, a weighing pan 3 fixedly connected to the middle upper end of the workbench 1, a limit mechanism 4 fixedly connected to the upper end of the weighing pan 3, support legs 5 fixedly connected to the four corners of the lower end of the workbench 1, and a testing mechanism 6 fixedly connected to the rear middle upper end of the workbench 1.

[0023] In this embodiment, the detection mechanism 6 includes a bracket 7. A connecting seat 8 is fixedly connected to the front of the middle part of the upper end of the bracket 7. A hydraulic rod 9 is fixedly connected to the output end of the connecting seat 8. A pressing plate 10 is fixedly connected to the lower end of the hydraulic rod 9. A protective mechanism 11 is fixedly connected to the inner wall of the upper part of the bracket 7. The protective mechanism 11 includes a first protective frame 12. Limiting holes 13 are opened at the upper left end, lower left end, upper right end, and lower right end of the first protective frame 12. A second protective frame 14 is movably connected to the outer surface of the first protective frame 12. Telescopic positioning rods 15 are movably arranged at the upper left end and upper right end of the second protective frame 14. The telescopic positioning rods 15 are inserted and engaged with the nearby limiting holes 13. The first protective frame 12 is fixedly connected to the lower inner wall of the bracket 7. The hydraulic rod 9 and the pressing plate 10 are both located inside the first protective frame 12 and the second protective frame 14.

[0024] Through the above scheme: the connecting seat 8 on the bracket 7 drives the hydraulic rod 9 and the pressing plate 10 to perform strength tests on the lower parts. At the same time, the protective mechanism 11 at the lower end of the bracket 7 can protect against flying debris during use. The first protective frame 12 and the second protective frame 14 can form a relatively closed space to prevent debris from flying.

[0025] In this embodiment, the limiting mechanism 4 includes a rectangular platform 17. Rectangular grooves 18 are opened at the upper front and upper rear of the rectangular platform 17. A motor 19 is fixedly connected to the left inner wall of the front rectangular groove 18. A screw 20 is fixedly connected to the output end of the motor 19. A slide rod 21 is fixedly connected between the left and right inner walls of the rear rectangular groove 18. A limiting plate 22 is threadedly engaged between the left and right sides of the screw 20 and the slide rod 21. Rollers 23 are movably connected to the lower front and lower rear of the two sets of limiting plates 22 through a U-shaped rod. Several sets of cleaning grooves 24 are opened at equal intervals in the middle of the upper end of the rectangular platform 17. The rectangular platform 17 is fixedly connected to the weighing pan 3. The rollers 23 are in contact with but not fixed to the lower inner wall of the rectangular groove 18.

[0026] With the above solution, the limiting plate 22 on the limiting mechanism 4 can move left and right under the drive of the motor 19 and the screw 20, clamping and fixing irregularly shaped parts, which is convenient for subsequent strength testing. Cleaning grooves 24 are opened on both the rectangular platform 17 and the worktable 1, which can conveniently let the debris fall down along the cleaning grooves 24.

[0027] It should be noted that this utility model is a strength testing device for automotive parts. During use, the part is first placed at the upper center of the rectangular platform 17. When dealing with irregularly shaped parts, the motor 19 inside the rectangular groove 18 is driven. The screw 20 at the output end of the motor 19 is driven, and the limiting plate 22, which is threaded and engaged with the sliding rod 21, is moved left and right, clamping and fixing the irregularly shaped part. This fixes the part for easier subsequent testing. The roller 23, which is movable at the lower end of the limiting plate 22, facilitates smoother movement of the limiting plate 22. Rubber points are fixedly connected to the limiting plate 22 to prevent excessive compression of the parts. Then, the operating disc 2 is used to drive the connecting seat 8 and the hydraulic rod 9 at the output end, which can drive the lower pressing plate 10. The pressing plate 10 can press and test the parts. Before pressing, the telescopic positioning rod 15 on the second protective frame 14 and the limiting round hole 13 on the upper part of the first protective frame 12 can be pulled out. The second protective frame 14 is moved down, and the telescopic positioning rod 15 is engaged with the lower limiting round hole 13. The first protective frame 12 and the second protective frame 14 together form a relatively closed space to prevent debris from flying.
