Description

Technical Field

[0001] This utility model relates to the field of slewing bearing testing technology, specifically a dual-station slewing bearing testing machine. Background Technology

[0002] The slewing bearing testing machine is a testing device used to simulate the dynamic performance of slewing bearings under complex working conditions. Existing testing machines typically consist of a base frame, a hydraulic loading system, a torque measurement unit, and a workpiece clamping mechanism. Its core function is to apply multi-directional composite loads such as axial force, radial force, and overturning moment to the slewing bearing through the loading system, and to detect key performance parameters.

[0003] The slewing bearings of existing testing machines are mainly connected to the test bench base by bolts. The disassembly and assembly process requires special wrenches to loosen or tighten the bolts, which is cumbersome and time-consuming. For large or high-precision slewing bearings, frequent disassembly and assembly can easily lead to bolt stripping, thread wear, or positioning deviation. Repeated calibration is required to ensure installation accuracy, which seriously affects the testing efficiency. In addition, the bolted connection structure is prone to stress concentration or corrosion jamming under long-term high-frequency loads, which further increases the maintenance difficulty and downtime risk. Especially in batch testing scenarios, it increases labor and time costs.

[0004] Some existing devices use a fixed structure, which can only complete multiple tests by stopping the machine and switching workpieces. Each test requires stopping the loading system, disassembling the current workpiece, installing a new workpiece, and recalibrating the parameters, which reduces testing efficiency. For quality inspection scenarios in mass production, existing devices need to be started and stopped frequently, which not only affects the life of the equipment but also makes it difficult to achieve automated continuous testing. This cannot meet the needs of modern manufacturing for efficient and intelligent testing equipment. In addition, during the shutdown operation, there may be safety hazards caused by accidental activation of the loading system or incorrect parameter reset. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

This reduces the need for frequent machine stops and manual repositioning when testing the next slewing bearing body, effectively improving the convenience of equipment use.

[0023] 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.

[0024] Please see Figure 1-6As shown, a dual-station slewing bearing testing machine includes a test bench 1. An adjustment mechanism 2 is provided on the surface of the test bench 1. A connecting column 3 is slidably connected to the inner wall of the adjustment mechanism 2. A servo motor 4 is fixedly connected to one end of the connecting column 3 and is installed in the inner cavity of the test bench 1. A rotating column 5 is fixedly connected to the other end of the connecting column 3. A rotating table 6 is fixedly connected to the surface of the rotating column 5. A slewing bearing body 7 is mounted on the surface of the rotating table 6. With the cooperation of the adjustment mechanism 2 and the rotating column 5, the rotating table 6 can reciprocate, thereby changing the position of the slewing bearing body 7 mounted on the surface of the rotating table 6. This reduces the need for frequent machine stops and manual position changes when testing the next slewing bearing body 7, effectively improving the convenience and testing efficiency of the equipment. A clamping mechanism 8 is provided on the surface of the rotating table 6. The clamping mechanisms 8 are symmetrically arranged on the surface of the rotating table 6. A connecting rod 9 passes through the inside of the clamping mechanism 8, and a rotating mechanism 10 is provided at one end of the connecting rod 9. The connecting rod 9 and the rotating mechanism 10 work together. Under the action of the rotating mechanism 10, the clamping mechanism 8 can be unfolded, so that the clamping mechanism 8 fits against the inner wall of the slewing bearing body 7, thereby fixing the slewing bearing body 7. This reduces the complicated operation of using multiple sets of bolts to fix the slewing bearing body 7 during installation, making the slewing bearing body 7 more stable during subsequent testing and inspection, and effectively improving the convenience and practicality of the entire equipment. An electric push rod 11 is fixedly connected to one end of the surface of the test bench 1, and a movable table 12 is fixedly connected to the other end of the electric push rod 11. A drive motor 13 is fixedly connected to one end of the surface of the movable table 12. A transmission gear 14 is fixedly connected to the output end of the rotating mechanism 10. The drive motor 13 can provide power to the transmission gear 14 to make it rotate. Under the action of the electric push rod 11, the transmission gear 14 can approach the slewing bearing body 7 and mesh to make it rotate, thereby facilitating the equipment to test the slewing bearing body 7.

[0025] The adjustment mechanism 2 includes a rotating shell 21 fixed to the surface of the rotating platform 6. The inner wall of the rotating shell 21 is provided with a fixing groove 22. A ball bearing 23 slides inside the fixing groove 22. There are several balls bearing 23. Under the action of the balls bearing 23, the friction of the rotating column 5 can be reduced when it rotates. The rotating shell 21 is provided with a sliding groove 24. A support column 25 slides inside the sliding groove 24. There are several support columns 25. One end of the support column 25 is fixedly connected to the bottom of the rotating platform 6. With the cooperation of the support column 25 and the sliding groove 24, the rotating platform 6 can be supported, making it more stable when it rotates.

[0026] The clamping mechanism 8 includes a fixed column 81 fixed to the surface of the rotating table 6. The fixed column 81 has a movable groove 82 inside. A support block 83 slides inside the movable groove 82. A sliding column 84 is fixedly connected to the surface of the support block 83. There are several support blocks 83 and sliding columns 84. One end of the connecting rod 9 is fixedly connected to a movable disk 85. A limit groove 86 is opened inside the movable disk 85. The movable groove 82 slides inside the limit groove 86. Under the action of the movable disk 85 and the limit groove 86, the sliding column 84 can move along the shape of the limit groove 86. With the cooperation of the movable groove 82, the support block 83 slides in the inner cavity of the movable groove 82, so that the support block 83 can quickly close and fit against the inner wall of the slewing bearing body 7. This limits and fixes the slewing bearing body 7, reducing the complicated operation of using multiple sets of bolts to fix the slewing bearing body 7 during installation. This makes the slewing bearing body 7 more stable during subsequent testing and inspection, and effectively improves the convenience and practicality of the entire equipment.

[0027] The rotating mechanism 10 includes a synchronous gear 101 fixed to the other end of the connecting rod 9. The synchronous gear 101 is meshed with a rack plate 102. One end of the rack plate 102 is fixedly connected to a hydraulic rod 103. One end of the hydraulic rod 103 is fixedly connected to a connecting block 104. The connecting block 104 can fix the hydraulic rod 103, making it more stable when moving. One side of the connecting block 104 is fixedly connected to a part of the bottom surface of the rotating table 6. With the cooperation of the hydraulic rod 103, the connecting rod 9 and the rotating mechanism 10, the movable disc 85 can be driven to move, which can make the support block 83 retract quickly, thereby quickly fixing the slewing bearing body 7.

[0028] It is worth noting that the technical features such as the slewing bearing body 7 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0029] Working principle: First, the slewing bearing body 7 to be tested is aligned with the clamping mechanism 8. The hydraulic rod 103 is activated to push the rack plate 102 horizontally. Through the meshing transmission between the synchronous gear 101 and the rack plate 102, the connecting rod 9 rotates. Simultaneously, the connecting rod 9 causes the movable disc 85 to rotate. Under the action of the movable disc 85 and the sliding column 84, the support block 83 unfolds within the movable groove 82. When the outer edge of the support block 83 is completely in contact with the inner wall of the slewing bearing body 7, the slewing bearing body 7 is clamped and fixed. This reduces the complex operation of using multiple sets of bolts for fixing the slewing bearing body 7 during installation, making subsequent testing and inspection of the slewing bearing body 7 easier. The system is stable and effectively improves the convenience and practicality of the entire equipment. After the slewing bearing body 7 is fixed, the operator turns on the servo motor 4, which causes the rotating column 5 to rotate, thereby driving the rotating table 6 to rotate back and forth, so that the slewing bearing body 7 to be tested rotates to a symmetrical position. The next slewing bearing body 7 to be tested can be placed on another part of the surface of the rotating table 6, which reduces the need to frequently stop the machine to manually change its position when testing the next slewing bearing body 7, effectively improving the convenience and testing efficiency of the equipment. Subsequently, under the action of the drive motor 13, the transmission gear 14 is driven to mesh and rotate with the slewing bearing body 7, thereby facilitating the testing of the slewing bearing body 7.
