Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing technology, specifically a multi-station impact testing machine for impact resistance testing of automotive parts. Background Technology

[0002] Before a car leaves the factory for sale, all its components need to be tested. These components are more likely to be impacted or subjected to heavy objects during use, which may cause cracks or even complete breakage. They are also prone to damage during production and assembly due to operational errors or unexpected impacts from heavy objects. Therefore, impact tests are required for car components to simulate external environmental or sudden impacts and to test whether they will break under specified impact conditions. If the damage is within the expected range, the tested component is qualified; if the damage exceeds the specified range, the tested component is unqualified.

[0003] The aforementioned impact testing machine still has some problems in use. Traditional impact testing machines are single-station tests, which simply use a drive component to drive an impact block to impact the parts. Only one part can be tested at a time. In order to fully understand the impact resistance of the parts, it is necessary to adjust the driving pressure of the drive component and understand the damage of the parts under different pressures. The single-station testing machine results in low testing efficiency. Therefore, in order to address the above problems, a multi-station impact testing machine for automotive parts impact resistance testing is proposed. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this application can realize multi-station clamping testing, and the workpiece can be positioned and adjusted. It can test the workpiece's resistance under different pressures, greatly improving the efficiency of impact resistance testing of parts. This utility model proposes a multi-station impact testing machine for impact resistance testing of automotive parts.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The multi-station impact testing machine for automotive parts impact resistance testing of this utility model includes a support frame, a test platform is arranged inside the upper part of the support frame, and a top plate is fixedly connected to the top of the support frame. A protective frame is slidably connected to the side of the support frame. A base is arranged inside the lower part of the support frame. A motor is fixedly connected to one side of the base. A gear ring is fixedly connected to the output end of the motor. The gear ring is meshed with the lower side of the test platform. A first cylinder is fixedly connected inside the base. A set of fixing plates is fixedly connected to the top surface of the test platform. A sliding plate that is slidably connected to the test platform is symmetrically arranged on one side of the fixing plate. A pressure strip is fixedly connected to the bottom of the sliding plate. The output end of the first cylinder is rotatably connected to a lifting plate, the lifting plate is slidably connected to the test bench, and the lifting plate is arranged in a cross shape. The four ends of the lifting plate are fixedly connected to a first extrusion block and a second extrusion block. A set of observation windows is fixedly connected to the side of the protective frame, and a dust-collecting component for absorbing dust caused by the impact test is provided on one side of the protective frame.

[0011] Preferably, the top surface of the protective frame is fixedly connected to four corners with snap-fit ​​blocks, and the snap-fit ​​blocks are snap-fitted to the support frame.

[0012] The advantages of this utility model are: 1. This utility model uses a first cylinder to drive a lifting plate to descend vertically, causing a second pressing block to press the inclined surface at the top of the pressure strip. This causes a sliding plate to move inward, which, together with a fixed plate, clamps and fixes the workpiece. The protective frame is then pulled upward. After that, the second cylinder is activated, causing the impact hammer to descend vertically and perform an impact test on the workpiece clamped between the fixed plate and the sliding plate.

During the test, the fan is activated, and dust and debris caused by the impact inside the protective frame are sucked in by the suction pipe. Then, the corrugated pipe guides the debris into the fixed frame, where it is filtered by a filter screen. After the test, the dust collection box is pulled outwards to collect and clean the absorbed dust and impurities. This application allows for sealing adjustment, reducing the problem of dust and debris floating around during impact tests. It also allows for the absorption and collection of these materials for centralized processing, thus purifying the test environment. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0017] Please see Figure 1 one Figure 6 As shown, a multi-station impact testing machine for automotive parts impact resistance testing includes a support frame 1. A test bench 3 is arranged inside the upper part of the support frame 1, and a top plate 4 is fixedly connected to the top of the support frame 1. A protective frame 2 is slidably connected to the side of the support frame 1. A base 5 is arranged inside the lower part of the support frame 1. A motor 6 is fixedly connected to one side of the base 5. A gear ring 7 is fixedly connected to the output end of the motor 6. The gear ring 7 is meshed with the lower side of the test bench 3. A first cylinder 8 is fixedly connected inside the base 5. A set of fixing plates 11 is fixedly connected to the top surface of the test bench 3. A sliding plate 12 is symmetrically arranged on one side of the fixing plate 11 and slidably connected to the test bench 3. A pressure strip 18 is fixedly connected to the bottom of the sliding plate 12. The output end of the first cylinder 8 is rotatably connected to the lifting plate 15. The lifting plate 15 is slidably connected to the test bench 3, and the lifting plate 15 is arranged in a cross shape. The four ends of the lifting plate 15 are fixedly connected to the first extrusion block 16 and the second extrusion block 17. A set of observation windows 19 are fixedly connected to the side of the protective frame 2, and a dust collection component for absorbing dust caused by the impact test is provided on one side of the protective frame 2. Traditional impact testing machines operate on a single-station basis, relying solely on a drive unit to move an impact block to strike the component. Only one component can be tested at a time. Furthermore, to fully understand the impact resistance of the component, the driving pressure needs to be adjusted to assess the damage under different pressures. This single-station design results in low testing efficiency. By using multiple fixed plates 11 and multiple sliding plates 12 in cooperation, multiple workpieces can be clamped and fixed. The motor 6 drives the gear ring 7 to rotate, thereby rotating the test platform 3 and adjusting the position of different workpieces. This enables multi-station testing and improves testing efficiency.

[0018] Furthermore, the dust collection assembly includes a fan 21 fixedly connected to the outside of the support frame 1, a corrugated pipe 22 is provided above the fan 21, a dust collection pipe 23 located inside the protective frame 2 is fixedly connected to the top of the corrugated pipe 22, and a filter assembly for dust filtration is provided at the connection between the corrugated pipe 22 and the fan 21. During operation, the fan 21 is started, and the dust and debris caused by the impact inside the protective frame 2 are sucked in by the suction pipe 23. Then, the corrugated pipe 22 guides the dust into the fixed frame 24, completing the absorption of dust and purifying the test environment.

[0019] Furthermore, the filter assembly includes a fixed frame 24 that is fixedly connected to the top surface of the fan 21 and the bottom end of the corrugated pipe 22. A dust collection box 25 is slidably connected to the inner side of the fixed frame 24, and a filter screen 26 is fixedly connected to the bottom of the dust collection box 25. During operation, the filter is filtered through the filter screen 26. After the test, the dust collection box 25 can be pulled out to collect and clean the absorbed dust and impurities.

[0020] Furthermore, a set of second cylinders 9 are fixedly connected to the top of the top plate 4, and an impact hammer 10 is fixedly connected to the output end of the second cylinder 9. The impact hammer 10 is located directly above the fixed plate 11 and the sliding plate 12. During operation, the second cylinder 9 is activated, which drives the impact hammer 10 to descend vertically and perform an impact test on the workpiece clamped between the fixed plate 11 and the sliding plate 12. The impact pressure is different between different impact hammers 10, so the workpiece's ability to withstand different pressures can be tested.

[0021] Furthermore, a guide ring 13 is fixedly connected to the bottom of the test bench 3, and a set of balls 14 are rotatably connected to both sides of the guide ring 13, and the guide ring 13 is rotatably connected to the top surface of the base 5. During operation, the guide ring 13, in conjunction with the ball bearing 14, serves to limit and guide the rotation, ensuring the stability of the test bench 3.

[0022] Furthermore, both sides of the pressure strip 18 are inclined, the first extrusion block 16 is adapted to the inclined surface at the bottom of the pressure strip 18, and the second extrusion block 17 is adapted to the inclined surface at the top of the pressure strip 18. During operation, the first cylinder 8 is activated, causing the lifting plate 15 to descend vertically. The lifting plate 15 causes the first pressing block 16 to separate from the pressure bar 18. At the same time, the second pressing block 17 presses the inclined surface at the top of the pressure bar 18, which causes the sliding plate 12 to move inward, cooperating with the fixing plate 11 to clamp and fix the workpiece. Conversely, the first cylinder 8 causes the lifting plate 15 to rise vertically, which causes the second pressing block 17 to separate from the pressure bar 18. At the same time, the first pressing block 16 presses the inclined surface at the bottom of the pressure bar 18, which causes the sliding plate 12 to move outward, thus removing the workpiece.

[0023] Furthermore, the top surface of the protective frame 2 is fixedly connected to four corners with snap-fit ​​blocks 20, and the snap-fit ​​blocks 20 are snap-fitted to the support frame 1. During operation, pull the protective frame 2 upwards, and fix the position of the protective frame 2 by the snap-fit ​​block 20. Then the support frame 1 is in a sealed state, preventing debris and dust caused by the impact test from floating around.

[0024] Working principle: First, place multiple automotive parts on one side of multiple fixed plates 11. Start the first cylinder 8 to drive the lifting plate 15 to descend vertically. The lifting plate 15 drives the first pressing block 16 to separate from the pressure strip 18. At the same time, the second pressing block 17 presses the inclined surface at the top of the pressure strip 18, which drives the sliding plate 12 to move inward. It works with the fixed plate 11 to clamp and fix the workpiece. Pull the protective frame 2 upward and fix the position of the protective frame 2 through the snap-fit ​​block 20. Then the support frame 1 is in a sealed state to prevent debris and dust caused by the impact test from floating around.

[0025] After the workpiece is clamped, the second cylinder 9 is activated, which drives the impact hammer 10 to descend vertically and conduct an impact test on the workpiece clamped between the fixed plate 11 and the sliding plate 12. The motor 6 drives the gear ring 7 to rotate, thereby rotating the test bench 3 and adjusting the position of different workpieces to achieve multi-station testing, improve test efficiency, and the impact pressure between different impact hammers 10 is different, so that the workpiece can be tested under different pressures.

[0026] During the test, the fan 21 is started, and the dust and debris caused by the impact inside the protective frame 2 are sucked in by the suction pipe 23. Then the corrugated pipe 22 guides it into the fixed frame 24, where it is filtered by the filter screen 26. After the test, the dust collection box 25 is pulled out to the outside, and the absorbed dust and impurities can be cleaned in a concentrated manner.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, or similar improvements made within the theoretical and principle content of the present utility model should be included within the protection scope of the present utility model.
