Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of robot production, and in particular relates to a robot load-bearing testing device. Background Art
[0002] Transport robots, also known as handling robots, are industrial robots that can perform automated handling operations. The earliest handling robots appeared in the United States in 1960. The Versatran and Unimate robots were first used for handling operations. Handling operations refer to holding a workpiece with a device and moving it from one processing location to another. Handling robots can be equipped with different end effectors to complete the handling of workpieces of various shapes and states, greatly reducing the heavy physical labor of humans. However, in the production process of transport robots, load testing is one of the essential inspection items for transport robots. Nowadays, the load testing method for transport robots usually uses a hydraulic press as the downward pressure to measure the load capacity of the transport robot. However, since this measurement method can only be performed on a flat ground in place, it cannot be performed while the transport robot is driving, the measured data cannot accurately match the data effect during actual use.
[0003] Therefore, it is necessary to provide a robot load-bearing test device to solve the above problems. Summary of the Invention
[0004] The purpose of the present invention is to provide a robot load-bearing test device. Through the design of the transport robot load-bearing test device, the problem in the existing technology that the test cannot be performed while the transport robot is moving, resulting in the data not being accurately close to the data effect of the actual use process is solved.
[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions:
[0006] The present invention is a robot load-bearing test device, comprising a device plate, a mover, and a drive box. The mover is movably connected to the opposite inner side surfaces of the device plate, and the drive box is frictionally connected to the top of the device plate.
[0007] The two ends of the device plate are fixedly connected to support rods, and the inner side surfaces opposite to the bottom ends of the support rods are movably connected to the conveyor belts. The opposite inner side surfaces of the device plate are clamped with limit plates, and the opposite inner side surfaces of the limit plates are provided with limit slide rails, and track grooves are provided on both sides of the inner side of the limit slide rails.
[0008] The two ends of the mover are movably connected to moving wheels on both sides, the two ends of the front side of the mover are clamped with sleeve rods, the interior of the sleeve rods is clamped with a spiral rod, the side of the spiral rod is threadedly connected to an extension rod, the bottom end of the extension rod is fixedly connected to a fixing hook, and the bottom end of the fixing hook is clamped with a pressure plate;
[0009] The interior of the drive box is fixedly connected to a drive motor, the bottom end of the drive motor is movably connected to a drive gear, the side of the drive gear is frictionally connected to a transmission track, the two ends of the inner side of the transmission track are movably sleeved with transmission gears, and the bottom of the transmission gear is fixedly connected to a fixing rod.
[0010] Preferably, a transmission motor is installed inside the mover, and both ends of the transmission motor are connected to connecting rods, and both ends of the connecting rods are fixedly connected to the center positions of the moving wheels on both sides.
[0011] Preferably, the bottom end of the fixing rod is fixedly connected to the top end of the spiral rod.
[0012] Preferably, both sides of the mover are frictionally connected to the inner side of the limiting slide rail.
[0013] Preferably, the side of the moving wheel and one side inside the track groove are both provided with gear patterns, and the gear patterns are engaged with each other.
[0014] Preferably, the driving gear, the side of the transmission gear and the inner side of the transmission track are all provided with gear patterns, and the gear patterns are engaged with each other.
[0015] Preferably, the fixing hooks are clamped on both sides of the bottom of the pressing plate, and the bottom of the fixing hooks is flush with the bottom of the pressing plate.
[0016] Preferably, the side of the extension rod is frictionally connected to the inner side of the sleeve rod.
[0017] The present invention has the following beneficial effects:
[0018] When the vehicle moves to the end of the limiting slide rail, the pressure plate separates from the carrying platform and returns to the original point driven by the mover to test the mechanical properties of the vehicle.
[0019] 2. The present invention can realize free adjustment of height through the design of the spiral rod, the sleeve rod and the extension rod. After the transmission gear rotates, the rotating gear drives the spiral rod to rotate. Under the action of the thread between the spiral rod and the extension rod that is movably sleeved inside the sleeve rod, the extension rod moves up and down, so that it can be adjusted according to the height of the carrying platform of different transport robots, ensuring that the pressure plate is effectively placed on the carrying platform for load testing.
[0020] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.
[0030] See also Figure 1-5 The present invention is a robot load-bearing test device, comprising a device plate 1, a mover 7, and a drive box 14. The mover 7 is movably connected to the inner side surfaces of the device plate 1, and the drive box 14 is frictionally connected to the top of the device plate 1.
[0031] The two ends of the device plate 1 are fixedly connected to the support rods 2, and the inner side surfaces opposite to the bottom ends of the support rods 2 are movably connected to the conveyor belt 3. The opposite inner side surfaces of the device plate 1 are clamped with the limit plates 4, and the opposite inner side surfaces of the limit plates 4 are provided with limit rails 5. The two sides of the inner surface of the limit rails 5 are provided with track grooves 6.
[0032] The two ends of the mover 7 are movably connected to the moving wheels 8, the two ends of the front side of the mover 7 are clamped with sleeve rods 10, the inner part of the sleeve rod 10 is clamped with a spiral rod 11, the side of the spiral rod 11 is threadedly connected to an extension rod 12, and the bottom end of the extension rod 12 is fixedly connected to a fixing hook 13, and the bottom end of the fixing hook 13 is clamped with a pressing plate 20;
[0033] The interior of the drive box 14 is fixedly connected to a drive motor 15, and a drive gear 16 is movably connected to the bottom end of the drive motor 15. A transmission belt 17 is frictionally connected to the side of the drive gear 16. Transmission gears 18 are movably sleeved on both ends of the inner side of the transmission belt 17, and a fixing rod 19 is fixedly connected to the bottom of the transmission gear 18.
[0034] Furthermore, a transmission motor is installed inside the mover 7, and connecting rods 9 are connected to both ends of the transmission motor. The two ends of the connecting rods 9 are fixedly connected to the center positions of the moving wheels 8 on both sides. When the driving motor is started, the connecting rods 9 are driven to rotate and the moving wheels 8 are rotated at the same time.
[0035] Furthermore, the bottom end of the fixed rod 19 is fixedly connected to the top end of the spiral rod 11, so that when the fixed rod 19 rotates, the spiral rod 11 is driven to rotate at the same time. When the spiral rod 11 rotates, under the action of the thread on the side of the spiral rod 11 and the internal thread of the extension rod 12, when the spiral rod 11 rotates clockwise, the extension rod 12 gradually moves downward, and when the spiral rod 11 rotates counterclockwise, the extension rod 12 gradually moves upward.
[0036] Furthermore, the two sides of the mover 7 are frictionally connected to the inner side of the limiting slide rail 5, thereby ensuring that when the mover 7 moves inside the limiting slide rail 5, the mover 7 moves smoothly under the force of the mutual fit between the two sides of the mover 7 and the two sides inside the limiting slide rail 5.
[0037] Furthermore, gear patterns are provided on the side of the moving wheel 8 and one side inside the track groove 6, and the gear patterns are engaged with each other. During the rotation of the moving wheel 8, the force of the mutual engagement between the gear patterns inside the track groove 6 is used to ensure that the moving wheel 8 drives the mover 7 to move inside the limiting slide rail 5.
[0038] Furthermore, the sides of the driving gear 16, the transmission gear 18 and the inner side of the transmission belt 17 are all provided with gear patterns, and the gear patterns are engaged with each other. When the driving motor 15 is started, the driving gear 16 is driven to rotate. When the driving gear 16 rotates, the transmission belt 17 is driven to rotate under the action of the mutual engagement between the gear patterns. At this time, the transmission gear 18 is caused to rotate in the same direction under the action of the gear patterns inside the transmission gear 18.
[0039] Furthermore, the fixing hook 13 is clamped on both sides of the bottom of the pressure plate 20, and the bottom of the fixing hook 13 is flush with the bottom of the pressure plate 20. The pressure plate 20 has a movable weight, and the pressure plate 20 can be accumulated and increased. Therefore, when the fixing hook 13 drops, the bottom of the pressure plate 20 can be stably fitted on the transport platform of the transport robot.
[0040] Furthermore, the side of the extension rod 12 is frictionally connected to the inner side of the sleeve rod 10, so that when the spiral rod 11 rotates clockwise or counterclockwise, the extension rod 12 can move up and down smoothly inside the sleeve rod 10.
[0041] Working principle: First, four support rods 2 and two device plates 1 are set up, and the four support rods 2 are divided into two groups and respectively clamped at the two ends of the device plate 1, and then the limit plate 4 is clamped on the opposite inner side of the device plate 1. At the same time, the inner limit slide 5 opened by the limit plate 4 is slidably connected with the mover 7, and the moving wheel 8 is movably connected to the inner track groove 6 opened on both sides of the inner limit slide 5. The sleeve rods 10 are clamped at both ends of the front side of the mover 7, and the spiral rod 11 is clamped inside the sleeve rod 10, and the side of the extension rod 12 is clamped. The top of the screw rod 11 passes through the top of the sleeve rod 10, and the transmission gears 18 are movably connected at both ends of the drive box 14, and the drive motor 15 is fixedly connected to the middle of the drive box 14. At the same time, the drive gear 16 connected to the drive motor 15 and the side of the transmission gear 18 are movably sleeved on the inner side of a transmission track 17, and the fixing rod 19 provided at the bottom of the transmission gear 18 is fixedly connected to the top of the screw rod 11.
