Description

Technical Field

[0001] This invention relates to the field of automotive bumper processing technology, and in particular to an impact testing device for automotive bumper processing. Background Technology

[0002] As an important component of a car, the bumper is indispensable. The bumper plays a protective role for the front and rear of the car and can absorb energy and buffer when the vehicle is hit. After the bumper is manufactured, it needs to be subjected to impact testing to check whether it meets the standards.

[0003] However, most traditional testing devices are divided into hydraulic testing and pendulum impact testing. Hydraulic testing uses a hydraulic cylinder to slowly apply pressure to the bumper, but this method cannot achieve the effect of a car bumper being hit instantly in reality. Furthermore, the pendulum impact testing method has limitations because the distance between the rotating shaft and the impact hammer is inconvenient, making it impossible to adjust the impact force as needed. Therefore, this invention proposes an impact testing device for car bumper processing. Summary of the Invention

[0004] The main objective of this invention is to provide an impact testing device for automobile bumper processing, which can effectively solve the problems mentioned in the background art. However, most traditional testing devices are divided into hydraulic testing and pendulum impact testing. Hydraulic testing uses a hydraulic cylinder to slowly apply pressure to the bumper, but this method cannot achieve the effect of an instantaneous impact on the car bumper in reality. Furthermore, the pendulum impact testing method has limitations because the distance between the rotating shaft and the impact hammer is inconvenient, making it impossible to adjust the impact force as needed.

[0008] As a preferred embodiment of the present invention, the adjustment structure further includes a second positioning component, which works in conjunction with the first positioning component to enhance the fixing effect on the adjustment rod. The second positioning component includes two mounting plates and two serrated plates. The mounting plates are fixedly connected to the rotating shaft, and the serrated plates are fixedly connected to the adjustment rod. An electric push rod is provided on the outside of the mounting plate, and one end of the electric push rod passes through the mounting plate and is fixedly connected to the adjustment plate. The adjustment plate and the serrated plate are meshed and matched.

[0009] As a preferred embodiment of the present invention, two driving mechanisms are fixedly installed on the outside of the base. One end of the two driving mechanisms is fixedly connected by a clamping mechanism. The bumper body is fixed by the clamping mechanism. One end of the rope is rotatably connected to the impact hammer through a connecting ring.

[0010] As a preferred embodiment of the present invention, the adjusting rod has several reserved holes on its exterior, and the reserved holes of the insert rod and the adjusting rod are adaptively matched.

[0011] As a preferred technical solution of the present invention, a limiting structure is provided on the outside of the base. The limiting structure, together with the adjustment structure, is used to limit the position of the impact hammer. The limiting structure includes a fixed frame, which is fixedly connected to the base. A bidirectional lead screw and two guide rods are provided on the inner side of the fixed frame. One end of the bidirectional lead screw passes through the fixed frame and is fixedly connected to the output shaft of the second motor.

A hydraulic cylinder is fixedly provided on the outside of the base, and a push plate is fixedly provided on one end of the hydraulic cylinder.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting an adjustment structure, the device can adjust the impact force as needed, which improves the device's adaptability compared to the traditional pendulum impact test. The motor drives the shaft to slide on the inside of the adjustment rod, which allows the distance between the shaft and the impact hammer to be adjusted, improving the flexibility of force adjustment. The control component, together with the adjustment structure, helps to control the position of the shaft in the adjustment rod, thereby solving the problem of the fixed distance between the shaft and the impact hammer in the traditional device, so that the impact force of the device can be adjusted as needed. 2. By setting up a positioning component in conjunction with the adjustment structure, it is beneficial to fix the shaft after the position is adjusted. By using an electric push rod to act on the insertion rod and the connecting pipe, the insertion rod can pass through the reserved hole of the adjustment rod and the connecting pipe to complete the fixing of the shaft and the adjustment rod. 3. By setting up positioning component two in conjunction with the adjustment structure, the stability of the connection between the rotating shaft and the adjustment rod is further enhanced, which can ensure the stability of the device in the impact test. The electric push rod two acts on the adjustment plate, so that the adjustment plate and the serrated plate mesh, which makes up for the deficiencies of positioning component one and relieves the pressure on the insertion rod and the connecting pipe. 4. By setting a limiting structure in conjunction with an adjustment structure, it is beneficial to control the position of the impact hammer. The limiting frame can constrain the impact hammer, ensuring that the position of the impact hammer remains unchanged when the rotating shaft is adjusted inside the adjusting rod. This avoids the impact hammer shifting position and causing deviations in the impact test results. The limiting component in conjunction with the limiting structure is beneficial to restrict the position of the casters. Under the action of the electric push rod three, the limiting plate is inserted into the inner side of the limiting frame. The limiting plate constrains the position of the casters, ensuring that the position of the impact hammer remains unchanged when the rotating shaft is adjusted. 5. By setting up auxiliary structures in conjunction with adjustment and limiting structures, the device can be equipped with multiple testing methods. This allows the device to be transformed from the original pendulum impact test to a hydraulic test, improving the device's adaptability. Under the action of the hydraulic cylinder, the impact hammer moves inside the limiting frame via casters toward the bumper body to perform hydraulic impact testing. Attached Figure Description

[0018] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0019] like Figures 1-9 As shown, an impact testing device for automobile bumper processing includes a base 1 and a bumper body 4. A winding mechanism 5 and a support frame 6 are fixedly installed on the outside of the base 1. A rope 7 is installed on the inner side of the winding mechanism 5. An adjustment structure 8 is installed on the outside of the base 1. The adjustment structure 8 includes two mounting brackets 11, which are fixedly connected to the base 1. A slider 12 is slidably arranged on the inner side of the mounting bracket 11. A rotating shaft 13 is rotatably connected between the two sliders 12. An adjustment rod 14 is slidably arranged on the outer side of the rotating shaft 13, and an impact hammer 15 is rotatably connected to one end of the adjustment rod 14. The winding mechanism 5, together with the rope 7, is used to control the angle and position of the impact hammer 15.

[0020] The adjustment structure 8 allows the device to adjust the impact force as needed, improving the device's adaptability compared to the traditional pendulum impact test. The motor 18 slides the rotating shaft 13 inside the adjustment rod 14, allowing the distance between the rotating shaft 13 and the impact hammer 15 to be adjusted, thus improving the flexibility of force adjustment.

[0021] In this embodiment, the adjustment structure 8 also includes two sets of control components. The control components work with the adjustment structure 8 to control the impact force of the impact hammer 15. The control components include a shelf 16, which is fixedly connected to the mounting frame 11. A one-way screw 17 is rotatably provided on the inner side of the shelf 16, and one end of the one-way screw 17 passes through the shelf 16 and is fixedly connected to the output shaft of the motor 18. A slider 2 19 is threadedly connected to the outside of the one-way screw 17, and the slider 2 19 is fixedly connected to the corresponding slider 12.

[0022] The control component, together with the adjustment structure 8, can control the position of the rotating shaft 13 in the adjustment rod 14, thereby solving the problem of the fixed distance between the rotating shaft 13 and the impact hammer 15 in the traditional device, so that the impact force of the device can be adjusted as needed.

[0023] In this embodiment, the adjustment structure 8 further includes a positioning component 1, which works with the adjustment structure 8 to position the adjustment rod 14. The positioning component 1 includes two fixing plates 20, which are fixedly connected to the rotating shaft 13. Two electric push rods 21 are fixedly mounted on the outside of the fixing plates 20. One end of the two electric push rods 21 is fixedly connected by a fixing ring 22. Two insert rods 23 are fixedly mounted on the outside of one fixing ring 22, and two connecting pipes 24 are fixedly mounted on the outside of the other fixing ring 22. The insert rods 23 and the connecting pipes 24 are adaptively matched.

[0024] The positioning component 1, together with the adjustment structure 8, allows the rotating shaft 13 to be fixed after the position is adjusted. The electric push rod 21 acts on the insertion rod 23 and the connecting pipe 24, allowing the insertion rod 23 to pass through the reserved hole of the adjustment rod 14 and the connecting pipe 24 to complete the fixing of the rotating shaft 13 and the adjustment rod 14.

[0025] In this embodiment, the adjustment structure 8 also includes a second positioning component. The second positioning component works in conjunction with the first positioning component to enhance the fixing effect on the adjustment rod 14. The second positioning component includes two mounting plates 25 and two serrated plates 26. The mounting plates 25 are fixedly connected to the rotating shaft 13, and the serrated plates 26 are fixedly connected to the adjustment rod 14. An electric push rod 27 is provided on the outside of the mounting plate 25, and one end of the electric push rod 27 passes through the mounting plate 25 and is fixedly connected to the adjustment plate 28. The adjustment plate 28 and the serrated plates 26 mesh and match.

[0026] The second positioning component, together with the adjustment structure 8, can further enhance the stability of the connection between the rotating shaft 13 and the adjustment rod 14, ensuring the stability of the device during impact testing. The electric push rod 27 acts on the adjustment plate 28, causing the adjustment plate 28 and the serrated plate 26 to mesh, compensating for the deficiencies of the first positioning component and relieving the pressure on the insertion rod 23 and the connecting pipe 24.

[0027] In this embodiment, two drive mechanisms 2 are fixedly installed on the outside of the base 1. One end of the two drive mechanisms 2 is fixedly connected by a clamping mechanism 3. The bumper body 4 is fixed by the clamping mechanism 3. One end of the rope 7 is rotatably connected to the impact hammer 15 through a connecting ring.

[0028] The drive mechanism 2 controls the position of the clamping mechanism 3, which facilitates the installation and removal of the bumper body 4. Under the action of the winding mechanism 5, the rope 7 has the ability to wind up and unwind.

[0029] In this embodiment, the adjusting rod 14 has several reserved holes on its outside, and the reserved holes of the insert rod 23 and the adjusting rod 14 are compatiblely matched.

[0030] The insertion rod 23 is inserted into the reserved hole of the adjusting rod 14 under the action of the electric push rod 21. The connecting pipe 24, in conjunction with the insertion rod 23, can improve the stability of the connection.

[0031] In this embodiment, a limiting structure 9 is provided on the outside of the base 1. The limiting structure 9, together with the adjusting structure 8, is used to limit the position of the impact hammer 15. The limiting structure 9 includes a fixing frame 29, which is fixedly connected to the base 1. A bidirectional lead screw 30 and two guide rods 31 are provided on the inner side of the fixing frame 29. One end of the bidirectional lead screw 30 passes through the fixing frame 29 and is fixedly connected to the output shaft of the second motor 32. Two sliders 33 are slidably arranged between the outside of the bidirectional lead screw 30 and the two guide rods 31. A limiting frame 34 is fixedly provided on the outside of the sliders 33.

[0032] The limiting structure 9, together with the adjusting structure 8, can control the position of the impact hammer 15. The limiting frame 34 can constrain the impact hammer 15, so that when the rotating shaft 13 is adjusted inside the adjusting rod 14, the position of the impact hammer 15 can always remain still, avoiding the situation where the impact hammer 15 shifts position and causes deviation in the impact test results.

[0033] In this embodiment, four connecting rods 35 are fixedly installed on the outside of the impact hammer 15, and one end of the connecting rod 35 is rotatably equipped with a caster 36, which is adaptively matched with the limiting frame 34.

[0034] Under the action of motor 2 32, the limiting frame 34 limits the caster 36, and the impact hammer 15 moves inside the limiting frame 34 through the caster 36.

[0035] In this embodiment, a limiting component is provided on the outside of the limiting frame 34. The limiting component is used to limit the position of the caster 36. The limiting component includes a base plate 37, which is fixedly connected to the limiting frame 34. An electric push rod 38 is provided on the outside of the base plate 37. One end of the electric push rod 38 is fixedly connected to a limiting plate 39, and the limiting plate 39 and the limiting frame 34 are connected through each other.

[0036] The limiting component, together with the limiting structure 9, can restrict the position of the caster 36. Under the action of the electric push rod 38, the limiting plate 39 is inserted into the inner side of the limiting frame 34. The limiting plate 39 constrains the position of the caster 36, which can ensure that the position of the impact hammer 15 remains unchanged when the rotating shaft 13 is adjusted.

[0037] In this embodiment, an auxiliary structure 10 is provided on the outside of the base 1. The auxiliary structure 10, together with the adjustment structure 8 and the limiting structure 9, is used to change the usage mode of the impact hammer 15. The auxiliary structure 10 includes a base 40 and a connecting plate 41. The base 40 and the base 1 are fixedly connected, and the connecting plate 41 and the impact hammer 15 are fixedly connected. A hydraulic cylinder 42 is fixedly provided on the outside of the base 40, and a push plate 43 is fixedly provided on one end of the hydraulic cylinder 42.

[0038] The auxiliary structure 10, together with the adjustment structure 8 and the limiting structure 9, enables the device to have multiple testing modes, allowing the device to be transformed from the original pendulum impact test mode to the hydraulic test mode, thereby improving the device's work adaptability. Under the action of the hydraulic cylinder 42, the impact hammer 15 moves inside the limiting frame 34 via the caster 36 toward the bumper body 4 to perform hydraulic impact testing.

[0039] It should be noted that the present invention is an impact testing device for automobile bumper processing. Before use, the device is placed in the required location to achieve the working conditions. In the initial state, the adjusting rod 14 is perpendicular to the base 1, the adjusting plate 28 and the serrated plate 26 are engaged and connected, the insert rod 23 passes through the reserved hole of the adjusting rod 14 and the connecting pipe 24 and is inserted, and the limiting plate 39 is inserted into the inner side of the limiting frame 34. The device can have two usage modes according to the test requirements. Method 1: When a pendulum impact test is required, in the initial state of the device, the bumper body 4 to be tested is installed and fixed on the clamping mechanism 3. The bumper body 4 is moved to the predetermined area and then stopped by the drive mechanism 2. The motor 2 32 is started. When the motor 2 32 acts on the bidirectional lead screw 30, the two sliders 33 move towards the caster 36 with the corresponding limit frame 34 until the caster 36 is completely wrapped by the limit frame 34 and then stops. At this time, the caster 36 is located inside the limit frame 34 and is limited by the limit frame 34 and the limit plate 39. When adjusting the position of the rotating shaft 13 in the adjusting rod 14 according to the required impact force: Activate electric push rod 1 21 to move the insert rod 23 and the connecting tube 24 away from both ends of the adjusting rod 14 until electric push rod 1 21 is fully retracted and stops. At this time, the insert rod 23 and the connecting tube 24 are released from their constraint on the adjusting rod 14. Activate electric push rod 27 to move the adjusting plate 28 until the adjusting plate 28 and the serrated plate 26 separate and stop. At this time, the adjusting rod 14 is no longer restricted, and the rotating shaft 13 can slide freely on the adjusting rod 14. Activate motor 18 to make slider 2 19 slide with slider 1 12 outside the one-way lead screw 17 until the rotating shaft 13 moves to the predetermined position inside the adjusting rod 14 and stops. Electric push rod 1 21 causes the insert rod 23 and the connecting tube 24 to re-constrain the adjusting rod 14, and electric push rod 27 causes the adjusting plate 28 and the serrated plate 26 to re-engage and connect, strengthening the constraint on the adjusting rod 14. During the process, because the caster 36 is restricted by the limiting frame 34 and the limiting plate 39, the position of the impact hammer 15 does not change. The motor 32 causes the limiting frame 34 to return to its initial position, releasing the position restriction on the impact hammer 15. The winding mechanism 5 causes the rope 7 to act on the impact hammer 15 and rotate it around the pivot 13 towards the support frame 6 until it reaches a predetermined height and stops. The winding mechanism 5 releases the restriction on the rope 7, allowing it to be released freely. The impact hammer 15 loses tension and gradually moves towards the bumper body 4. During the movement, the impact hammer 15 converts potential energy into kinetic energy, ultimately causing the impact hammer 15 to strike the bumper body 4 for impact testing. It should be noted that adjusting the distance between the pivot 13 and the impact hammer 15 results in a smaller impact force and a larger impact force. Also, the smaller the angle between the adjusting rod 14 and the vertical direction, the smaller the impact force and the larger the angle, the larger the impact force. Method 2: When hydraulic testing is required, in the initial state of the device, start motor 2 32. With motor 2 32 acting on the bidirectional lead screw 30, the two sliders 33, along with the corresponding limiting frames 34, move towards the caster 36 until the caster 36 is completely enclosed by the limiting frames 34. At this time, the caster 36 is located inside the limiting frame 34 and positioned by the limiting plate 39. Install the bumper body 4 to be tested onto the clamping mechanism 3 and fix it. Move the bumper body 4 to the predetermined area and stop through the drive mechanism 2. Start electric push rod 1 21 to move the insert rod 23 and the connecting pipe 24 away from the two ends of the adjusting rod 14 until the electric push rod 1 21 is fully retracted and stops. At this time, the insert rod 23 and the connecting pipe 24 are released from the constraint on the adjusting rod 14. Start electric push rod 27 to move the adjusting plate 28 until the adjusting plate 28 and the serrated plate 26 separate and stop. At this time, the adjusting rod 14 is unrestricted, and the rotating shaft 13 is on the adjusting rod 14. The device can slide freely. Motor 18 moves the rotating shaft 13 towards the impact hammer 15 to a predetermined position and then stops, releasing the constraint of the winding mechanism 5 on the rope 7. The rope 7 will then perform corresponding defensive work as the impact hammer 15 moves. Electric push rod 38 is activated to move the limiting plate 39 upward until it leaves the inside of the limiting frame 34 and stops, so that the limiting plate 39 will not obstruct the movement of the caster 36. Hydraulic cylinder 42 is activated, and hydraulic cylinder 42 acts on push plate 43 to move towards connecting plate 41. After push plate 43 contacts connecting plate 41, it acts on impact hammer 15 to move towards bumper body 4. At the same time, caster 36 rotates inside the limiting frame 34. Impact hammer 15 moves one end of adjusting rod 14, causing adjusting rod 14 to gradually tilt. After the rotating shaft 13 is adjusted to the correct position, it will not obstruct the tilting of adjusting rod 14. Under the action of hydraulic cylinder 42, impact hammer 15 finally performs hydraulic testing on bumper body 4.
