[0002] As a core loading tool in the logistics and transportation field, the corner fittings of containers are key components for lifting, stacking, and securing containers. The holes on the corner fittings are the core parts that cooperate with spreaders, connectors, etc. During long-term use, the holes of the corner fittings will wear due to repeated friction with the mating parts. When the wear exceeds the limit, it will lead to an increase in the mating clearance, which will not only affect the stability and safety of container operation, but may also cause equipment failure or transportation accidents.
[0003] In the use of existing technologies, the industry mostly adopts actual working condition simulation testing methods, that is, by installing the corner pieces on simulated transportation or lifting equipment and subjecting them to long-term reciprocating friction operations to test their wear resistance life.
[0004] However, in actual use, the testing equipment is bulky, occupies a lot of space, and the testing process requires a lot of manpower and energy, which will also increase the workload of staff and thus increase costs. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a container corner fitting hole wear resistance testing device, which solves the problems that in actual use, the testing equipment is bulky, occupies a lot of space, and the testing process requires a lot of manpower and energy, which also increases the workload of staff and thus increases costs.

[0011] This utility model provides a container corner fitting hole wear resistance testing device. It has the following advantages: This device, through the cooperation of an adjusting device, a clamping plate, and a grinding head, uses the clamping plate to fix the workpiece, and under the drive of a hydraulic rod, the height of the grinding head is adjusted to meet the grinding position of the corner fitting hole. Simultaneously, driven by the adjusting device, the grinding head continuously grinds the corner fitting hole. This not only requires less space and is more convenient for operators, but also solves the problems of bulky testing equipment, which occupies a lot of space and requires a large amount of manpower and energy, increasing the workload of operators and thus raising costs.
[0012] Through the cooperation of the first servo motor, the driving gear, and the driven gear, the first servo motor drives the driving gear to rotate, and the meshing of the driving gear and the driven gear drives the lead screw to rotate synchronously, thereby causing the fixed cylinder to move on the outer wall of the lead screw, causing the clamping plate to move towards the workpiece, and under the linkage of the drive rod, the clamping plates on both sides synchronously clamp the workpiece, ensuring the stability of the workpiece during grinding. This solves the problem that existing testing devices require bolts to fix the workpiece, which makes it inconvenient for workers to disassemble. Attached Figure Description

Detailed Implementation
[0015] 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.
[0016] In actual use, the testing equipment is bulky, occupies a lot of space, and the testing process requires a lot of manpower and energy, which will also increase the workload of staff and thus increase costs.
[0017] In view of this, the present invention provides a container corner fitting hole wear resistance testing device, which solves the problems that in actual use, the testing equipment is bulky, occupies a lot of space resources, and the testing process requires a lot of manpower and energy, which will also increase the workload of staff and thus increase costs.
[0018] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.
[0019] Example 1: By Figure 1-4It is known that a container corner fitting hole wear resistance testing device includes a base 1, a clamping plate 4 is installed on the top of the base 1, a protective shell 2 is provided on the outer wall of the clamping plate 4, the bottom of the protective shell 2 is fixedly connected to the top of the base 1, a grinding head 3 is provided above the clamping plate 4, an mounting plate 5 is installed on the top of the grinding head 3, a second servo motor 20 is fixedly connected to the top of the mounting plate 5, the output end of the second servo motor 20 is fixedly connected to the top of the grinding head 3 through a sealed bearing, hydraulic rods 6 are fixedly connected to both sides of the top of the mounting plate 5, and sliders 7 are fixedly connected to the top of the two hydraulic rods 6, and an adjustment device is installed on the outer wall of the sliders 7. In the specific implementation process, it is worth noting that the base 1 is the basic support component of the device, and the clamping plates 4 are symmetrically arranged, which ensures stability when fixing the workpiece. Furthermore, the size of the grinding head 3 matches the diameter of the holes on the corner piece, facilitating grinding and testing. The grinding head 3 is made of tungsten carbide alloy, and the protective shell 2 is made of transparent polycarbonate sheet with a thickness of 5mm, providing good impact resistance and light transmission. Operators can clearly observe the internal testing process while effectively blocking metal debris and dust generated during testing. The second servo motor 20 is a high-precision servo motor with a rated power of 1.5kW and a speed adjustment range of 0-3000r / min. It can precisely adjust the speed of the grinding head 3 according to different testing standards and wear requirements. The motor has a built-in encoder that can provide real-time feedback of speed information. Closed-loop speed control is achieved through the control system, with a speed control accuracy of ±1r / min. The motor output... The device is directly connected to the grinding head 3, and with the support of the mounting plate 5, it ensures stability when the second servo motor 20 drives the grinding head 3 to grind the workpiece. The hydraulic rod 6 is a double-acting single-piston rod hydraulic cylinder with a cylinder diameter of 50mm, a piston rod diameter of 25mm, a maximum stroke of 200mm, and a working pressure range of 0-10MPa. The extension and retraction speed of the piston rod can be precisely controlled by the hydraulic control system, thereby adjusting the lifting speed of the grinding head 3 and the pressure on the anea corner fitting hole. The pressure control accuracy can reach ±0.05MPa, meeting the testing requirements under different wear pressure conditions. Moreover, the two hydraulic rods 6 are connected together by a synchronizer, so that the two hydraulic rods 6 are synchronized when lifting and lowering. The slider 7, driven by the adjustment device, will drive the grinding head 3 to adjust its position in the horizontal direction, meeting the wear resistance testing requirements of container corner fittings of different specifications and hole positions, greatly improving the versatility and testing range of the device. Furthermore, the adjustment device includes a fixed housing 17, a slide rod 8 is fixedly connected to the inner wall of the fixed housing 17, the slide rod 8 is inserted into the inner wall of the slider 7, and an electric telescopic rod 9 is fixedly connected to the outer wall of the slider 7, with the end of the electric telescopic rod 9 fixedly connected to the inner wall of the fixed housing 17. In the specific implementation process, it is worth noting that the fixed shell 17, as the basic load-bearing component of the auxiliary assembly of the adjustment device, ensures the stability of the entire adjustment device during operation. The surface of the slide rod 8 is precision ground and polished to reduce the frictional resistance with the inner wall of the slider 7. A pressure sensor can be installed between the slider 7 and the electric telescopic rod 9, which facilitates the adjustment and control of the pressure between the grinding head 3 and the inner wall of the corner fitting hole, adapting to different grinding intensities. Of course, the pressure sensor can also be connected to an external control terminal, so that the grinding pressure between the grinding head 3 and the inner wall of the corner fitting hole remains constant as the grinding head 3 grinds. The pressure of the grinding head 3 is set by the pressure sensor between the slider 7 and the electric telescopic rod 9, and the grinding time is controlled manually or by connecting to an external control system. After grinding, the deformation of the hole before and after grinding can be measured manually to determine whether the wear resistance of the corner fitting hole meets the requirements. Of course, the container corner fitting hole wear resistance testing device provided in this application is only an auxiliary testing device under standard conditions and is not recommended as the sole standard for testing the wear resistance of corner fitting holes. In practice, the "Series 1 Container Corner Fittings Technical Requirements" (GB / T) should be referred to. (1835-2023); Furthermore, a limit block 12 is provided below the grinding head 3, and the bottom of the limit block 12 is fixedly connected to the top of the base 1; In the specific implementation process, it is worth noting that the limiting block 12 is used to support the workpiece to ensure that the top of the workpiece is higher than the clamping plate 4 when it is fixed, so as to avoid the grinding head 3 being affected by the clamping plate 4 during grinding.
[0020] Example 2: From Figure 1-4 It is known that a fixed cylinder 19 is fixedly connected to the outer wall of the clamping plate 4, and a screw 14 is threadedly connected to the inner wall of the fixed cylinder 19. The outer wall of the screw 14 is rotatably connected to the inner wall of the protective shell 2 through a sealed bearing. A driven gear 18 is fixedly connected to one end of the screw 14 extending to the outside of the protective shell 2. A driving gear 13 is meshed with the outer wall of the driven gear 18. The outer wall of the driving gear 13 is movably connected to the inner wall of the base 1. A drive rod 11 is fixedly connected to the inner wall of the driving gear 13. The outer wall of the drive rod 11 is rotatably connected to the inner wall of the base 1 through a sealed bearing. A first servo motor 10 is fixedly connected to one end of the drive rod 11 extending to the outside of the base 1. The outer wall of the first servo motor 10 is fixedly connected to the outer wall of the base 1. The first servo motor 10 is electrically connected to a controller 16. The outer wall of the controller 16 is fixedly connected to the outer wall of the protective shell 2. In the specific implementation process, it is worth noting that the inner wall of the fixed cylinder 19 is provided with the same internal thread as the outer wall of the lead screw 14. When the lead screw 14 rotates, it will cause the fixed cylinder 19 to move on the outer wall of the lead screw 14, so that the clamping plate 4 fixes the workpiece. Moreover, the teeth on the outer walls of the driving gear 13 and the driven gear 18 mesh together. When the driving gear 13 rotates, it will drive the driven gear 18 to rotate synchronously, which will cause the lead screw 14 to rotate accordingly. Under the drive of the drive rod 11, the driving gears 13 and the driven gears 18 on both sides will rotate synchronously. This will cause the first servo motor 10 to drive the drive rod 11 to rotate, which will cause the clamping plates 4 on both sides of the top of the base 1 to move synchronously. This makes it stable when fixing the workpiece. The model of the first servo motor 10 is not limited, as long as it meets the actual use. At the same time, the operator can use the controller 16 to control the rotation of the first servo motor 10, which is convenient during operation. Furthermore, a limiting plate 15 is fixedly connected to the upper part of the outer wall of the clamping plate 4, and the outer wall of the limiting plate 15 is inserted into the inner wall of the protective shell 2. In the specific implementation process, it is worth noting that when the clamping plate 4 moves, it will drive the limiting plate 15 to move inside the protective shell 2. This can ensure that the clamping plate 4 is stable when it moves and ensure that the clamping plate 4 is stable when fixing the workpiece.
