Description

Technical Field

[0001] This invention relates to the field of AGV wheel testing technology, specifically to an AGV wheel wear resistance testing device. Background Technology

[0002] As a core piece of equipment in modern intelligent logistics systems, AGVs are widely used in warehousing, manufacturing, airports and other scenarios. Their operational stability and cost-effectiveness directly depend on the wear resistance of their wheels. During long-term, high-load, and high-frequency operation, AGV wheels must withstand the combined effects of vertical loads, horizontal friction, lateral steering forces and complex terrain, leading to gradual wear of the wheel material. This makes them prone to slipping on wet or sloping surfaces, threatening the safety of workers and equipment. To reduce the occurrence of such phenomena, it is necessary to conduct wear resistance tests on the wheels. Therefore, developing an AGV wheel wear resistance testing device is particularly important.

[0003] A forklift wheel wear resistance testing device, as described in CN204043929U, includes a workbench with at least one mounting bracket for mounting wheels, a drive mechanism connected to the mounting bracket, and a friction device for testing wheel wear resistance. The friction device includes a roller, a friction block disposed on the surface of the roller, and a motor driving the roller to rotate. The drive mechanism causes the wheel on the mounting bracket to contact the friction block, thereby performing the wear resistance test. This device is not only simple in structure and convenient for testing, but also highly efficient. The friction block has a triangular cross-section, making the wear resistance test resemble the wheel moving on a slope, increasing friction and thus more accurately detecting whether the wheel can withstand the required level of wear. However, while this device can be widely used, it is generally not convenient to drive the wheel to rotate for testing, nor is it easy to perform steering tests on the wheel. This makes it difficult for the device to achieve the expected testing results for the wheel, and further improvements are needed. Summary of the Invention

[0004] The purpose of this invention is to provide an AGV wheel wear resistance testing device to solve the problem that although the device proposed in the background art can be applied well, it is usually not easy to drive the wheel body for rotation testing and it is not easy to perform steering testing on the wheel body, making it difficult for the device to achieve the expected test results on the wheel body.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an AGV wheel wear resistance testing device, comprising a base, a vertical plate fixed to the top of the base, a base provided at the top of the base on one side of the vertical plate, a positioning frame fixedly installed on the upper end of the surface of the vertical plate, guide rods fixedly installed on the surfaces of the vertical plate on both sides of the positioning frame via brackets, a lifting plate movably connected to the outer wall of the guide rod, an electric push rod installed at the top of the positioning frame, the bottom end of the electric push rod penetrating the positioning frame and connected to the top of the lifting plate, a bearing seat fixed at the bottom of the lifting plate, a bearing column fixed at the bottom of the bearing seat, and a bearing column located away from the bearing seat. The device is equipped with a mounting plate. A first servo motor is mounted on one side of the top of the mounting plate. The bottom end of the first servo motor passes through the mounting plate and is equipped with a first gear. A second gear is rotatably mounted on the bottom end of the mounting plate on the side of the first gear. The second gear meshes with the first gear. A wheel frame is provided at the bottom end of the second gear. A second servo motor is mounted on the outer wall of the wheel frame. One end of the second servo motor passes through the wheel frame and is equipped with a wheel body. A control panel is fitted into the top of the base on the side away from the upright plate. The output terminal of the microcontroller inside the control panel is electrically connected to the input terminals of the electric push rod, the first servo motor, and the second servo motor, respectively.

[0006] Preferably, slide rails are fixedly installed on both sides of the top of the base, and two support plates are slidably connected to the top of the slide rails. A connecting plate is fixedly installed on the outer wall between the support plates to connect the two support plates.

[0007] Preferably, a telescopic cylinder is installed on one side of the top of the base. The input end of the telescopic cylinder is electrically connected to the output end of the microcontroller inside the control panel. One end of the telescopic cylinder is connected to the outer wall of a tray. The telescopic cylinder is used to drive the tray to slide on top of the slide rail.

[0008] Preferably, a cement test plate and an epoxy resin test plate are respectively provided on the top of the tray, and a support seat is provided at the corner of the top of the tray. The cement test plate and the epoxy resin test plate are provided to simulate different road surfaces to conduct wear resistance tests on the wheel body.

[0009] Preferably, both the cement test board and the epoxy resin test board are provided with an upper connecting seat at the corner of their bottom ends. A spring is installed at the bottom end of the upper connecting seat, and a lower connecting seat is installed at the end of the spring away from the upper connecting seat. The bottom end of the lower connecting seat is connected to the top end of the support seat. The spring is used to provide elastic support for the cement test board and the epoxy resin test board.

[0010] Preferably, a vibration motor is installed at the center of the bottom of both the cement test board and the epoxy resin test board. The input end of the vibration motor is electrically connected to the output end of the microcontroller inside the control panel. The vibration motor is configured to drive the cement test board and the epoxy resin test board to undergo vibration treatment.

[0011] Compared with the prior art, the beneficial effects of the present invention are: the AGV wheel wear resistance testing device is not only easy to perform wear resistance testing on the wheel body in two ways to ensure the wear resistance testing effect of the wheel body when the testing device is used, but also can reproduce the actual working conditions of AGV to perform wear testing on the wheel body, and achieves the purpose of easy dynamic loading wear resistance testing on the wheel body. The lifting plate is driven by an electric push rod to slide downward on the outer wall of the guide rod, so that the lifting plate drives the wheel body to move smoothly downward through the bearing seat and other components, so that the wheel body contacts the upper surface of the cement test plate or epoxy resin test plate. When the first servo motor drives the first gear to rotate, the wheel body can be driven to rotate slowly through the second gear to perform lateral wear resistance test on the wheel body. When the second servo motor drives the wheel body to rotate, the wheel body can be performed to perform walking wear resistance test. Because it is easy to perform wear resistance test on the wheel body in two ways, the wear resistance test effect of the test device is guaranteed when the test device is used. The two pallets are driven by the telescopic cylinder to slide on the top of the slide rail, so that the cement test plate and the epoxy resin test plate can be moved horizontally smoothly. When the cement test plate or epoxy resin test plate is moved to the bottom of the wheel, the wear resistance of the wheel can be tested as needed, simulating the actual ground surface. This allows the wear test of the wheel to be reproduced under the actual working conditions of the AGV. By using several springs, the cement test board and epoxy resin test board are elastically positioned above the support plate. When the vibration motor is started, the cement test board and epoxy resin test board can be driven to vibrate, simulating the unevenness of the workshop floor to perform wear resistance testing on the wheel body. This achieves the purpose of easily performing dynamic loading wear resistance testing on the wheel body. Attached Figure Description
