[0024] 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.
[0025] Please see Figures 1 to 5 This embodiment of a bearing cage mold strength testing device includes a workbench 1, a mounting frame 2 fixedly connected to the top of the workbench 1, a display screen 3 fixedly installed outside the mounting frame 2, and a mounting box 5 fixedly installed on the top of the workbench 1. A positioning seat 4 is fixedly connected to the top of the workbench 1. A clamping mechanism 6 extending to the outside of the mounting box 5 is provided inside the workbench 1. A testing mechanism 7 extending to the lower surface of the mounting frame 2 is provided on the upper surface of the workbench 1. A pick-and-place mechanism 8 is provided on the top of the workbench 1. The clamping mechanism 6 includes a bidirectional threaded rod 61 rotatably connected inside the mounting box 5, left and right moving blocks 62 threadedly connected to the outside of the bidirectional threaded rod 61, a connecting block 63 fixedly connected to the outside of the moving blocks 62, a clamping seat 64 fixedly connected to the end of the connecting block 63 away from the moving blocks 62, and a reciprocating motor 65 fixedly installed outside the mounting box 5.
[0026] The mounting box 5 has a bearing that is compatible with the bidirectional threaded rod 61 fixedly installed inside, and a limiting seat that is compatible with the bidirectional threaded rod 61 fixedly installed in the middle of the mounting box 5. The back of the moving block 62 is fixedly connected to a slider that extends into the interior of the mounting box 5. The interior of the mounting box 5 has a sliding groove that is compatible with the slider, and the slider and the sliding groove are slidably connected.
[0027] Specifically, the end of the bidirectional threaded rod 61 furthest from the mounting box 5 is fixedly connected to the output shaft of the reciprocating motor 65, which is electrically connected to the display screen 3. The reciprocating motor 65 is activated via the display screen 3, causing the bidirectional threaded rod 61 to rotate. This causes the two moving blocks 62 to move the connecting blocks 63 closer together or further apart, changing the distance between the clamping seats 64. This allows for clamping of molds of different sizes, accommodating bearing cage molds of varying dimensions and improving the flexibility and versatility of the inspection process.
[0028] It should be noted that there are two clamping seats 64, and both clamping seats 64 have arc-shaped fixing grooves inside.
[0029] In this embodiment, the detection mechanism 7 includes a hydraulic cylinder 71 fixedly installed on the upper surface of the mounting frame 2, a connecting plate 72 fixedly connected to the output end of the hydraulic cylinder 71, a pressure plate 73 fixedly connected to the bottom of the connecting plate 72, and a pressure sensor 74 fixedly installed on the upper surface of the connecting plate 72.
[0030] The pressure sensor 74 is electrically connected to the display screen 3. Two guide rods 75, extending to the upper surface of the mounting bracket 2, are fixedly connected to the top of the connecting plate 72. The guide rods 75 are slidably connected inside the mounting bracket 2. By setting the guide rods 75, the uniformity and stability of the preset force applied by the pressure plate 73 are improved, achieving the advantage of high practicality.
[0031] In this embodiment, the pick-and-place mechanism 8 includes a connecting frame 81 fixedly connected to the top of the workbench 1, a fixed cylinder 82 fixedly connected to the upper surface of the connecting frame 81, a slide rod 83 slidably connected to the inside of the fixed cylinder 82, a fixed plate 84 fixedly connected to the top of the slide rod 83, a vacuum suction cup 85 fixedly connected to the lower surface of the fixed plate 84, a compression sleeve 86 fixedly connected to the outer surface of the bottom end of the slide rod 83, a return spring 87 fixedly connected to the top of the compression sleeve 86, and an electric push rod 88 fixedly installed on the inner bottom wall of the connecting frame 81.
[0032] The slide rod 83 is rotatably connected to the inside of the fixed cylinder 82. A return spring 87 surrounds the outer surface of the slide rod 83 and abuts against the inner top wall of the connecting frame 81. An abutment plate 89 is fixedly connected to the output end of the electric push rod 88, abutting against the bottom of the extrusion sleeve 86. A pulley 810 is rotatably mounted on the outer surface of the slide rod 83. A guide groove 811 adapted to the pulley 810 is provided inside the fixed cylinder 82. The lifting and lowering movements of the slide rod 83, its fixed plate 84, and the vacuum suction cup 85 can be precisely controlled by the extension and retraction of the electric push rod 88. This facilitates precise placement or retrieval of the bearing retainer mold. By rotatably connecting the slide rod 83 inside the fixed cylinder 82, the entire pick-and-place mechanism 8 can rotate on a horizontal plane. This rotation function is very useful when adjusting the direction or angle of an object. The return spring 87 surrounding the outer surface of the slide rod 83 ensures that the slide rod 83 and its connected components stably return to their initial position when the electric push rod 88 is not applying force. By adapting the pulley 810 on the outer surface of the slide bar 83 to the guide groove 811 inside the fixed cylinder 82, this design not only provides stable support but also allows the slide bar 83 to move along a specific path during lifting, thereby enhancing the precision and stability of control. The vacuum suction cup 85 securely holds the bearing cage mold to be picked up or put down, ensuring that the object will not fall off or shift during lifting and rotation.
[0033] The working principle of the above embodiments is as follows:
[0034] During use, the lifting and lowering movements of the slide bar 83, its fixing plate 84, and the vacuum suction cup 85 can be precisely controlled by the telescopic movement of the electric push rod 88. This facilitates the precise placement or retrieval of the bearing cage mold. By setting the slide bar 83 to rotate inside the fixing cylinder 82, the entire pick-and-place mechanism 8 can rotate on a horizontal plane. This rotation function is very useful when it is necessary to adjust the orientation or angle of an object. The return spring 87, which surrounds the outer surface of the slide bar 83, ensures that the slide bar 83 and its connected components stably return to their initial position when the electric push rod 88 is not applying a pushing force. By adapting the pulley 810 on the outer surface of the slide bar 83 to the guide groove 811 inside the fixing cylinder 82, this design not only provides stable support but also allows the slide bar 83 to move along a specific path during lifting and lowering, thereby enhancing the precision and stability of control. By setting up a vacuum suction cup 85, the bearing cage mold to be picked up and placed can be firmly adsorbed, ensuring that the object will not fall off or shift during lifting and rotation. The reciprocating motor 65, activated via the display screen 3, drives the bidirectional threaded rod 61 to rotate, causing the two moving blocks 62 to move the connecting block 63 closer or further apart, thus changing the distance between the clamping seats 64 and enabling clamping of molds of different sizes, accommodating bearing cage molds of various dimensions. The hydraulic cylinder 71, activated via the display screen 3, extends and retracts, causing the connecting plate 72 and pressure plate 73 to move downwards, applying a preset force to the bearing cage, simulating the load under actual working conditions. The pressure sensor 74 measures the force on the mold during the inspection process, and the display screen 3 shows the measurement results for easy observation and analysis by the operator. The operator can determine whether the strength of the mold meets the requirements based on the data on the display screen 3.

In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
