Description

Technical Field

[0001] This utility model relates to the field of running-in testing technology, and in particular to a pin-type loading running-in test bench. Background Technology

[0002] A running-in test bench is a device used to test the performance and durability of mechanical components (such as shafts, pulleys, bearings, etc.) under actual operating conditions. It simulates the working environment and continuously tests the wear, vibration, temperature rise, and stability of components to ensure their reliability and lifespan in actual applications.

[0003] However, most traditional running-in test benches lack automatic or semi-automatic adjustment structures, making it difficult to quickly adapt to spindles of different lengths. The adjustment time is long and the operation is cumbersome. Furthermore, the clamping mechanism does not have locking components, which may cause loosening due to accidents during clamping.

[0004] Therefore, those skilled in the art have provided a pin-type loading and running-in test bench to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pin-type loading running-in test bench. This test bench is equipped with a clamping mechanism. Under the action of a second hydraulic telescopic rod, the connecting shaft can be tightly fitted to the spindle according to its length. This allows the device to be applicable to spindles of different lengths, improving the versatility of the equipment and reducing switching and adjustment time. Furthermore, under the action of the first hydraulic telescopic rod, the upper and lower clamping plates clamp and lock the spindle. Simultaneously, the locking frame, in conjunction with the second threaded rotating rod, can lock the upper and lower clamping plates after clamping. This achieves both flexible clamping of the spindle and ensures a firm and reliable locking mechanism, guaranteeing the stability of the test.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A pin-type loading running-in test bench includes a base and a main shaft. A drive mechanism is provided on one side of the front end of the upper surface of the base. The drive mechanism includes a support seat and a mounting seat. A drive housing is fixedly connected to the middle of the upper surface of the support seat. A drive shaft is rotatably connected to the center of one side of the outer wall of the drive housing. A first pulley is fixedly connected to one side of the outer wall of the drive shaft.

[0008] Positioning plates are fixedly connected to both sides of the rear end of the upper surface of the base. A clamping mechanism is provided on the upper surface of the positioning plate. The clamping mechanism includes an adjusting slide. A clamping seat is fixedly connected to one side of the upper surface of the adjusting slide. An upper clamping plate is hinged to the front end of the upper surface of the clamping seat. A placement groove is opened in the middle of the upper surface of the clamping seat. A first hydraulic telescopic rod is fixedly connected to the center of the bottom surface of the placement groove. A lower clamping plate is fixedly connected to the output end of the first hydraulic telescopic rod. A locking frame is slidably connected to the inner wall of the placement groove. A second threaded rotating rod is threadedly engaged at the center of the upper surface of the locking frame. A fixing seat is fixedly connected to the upper surface of one side of the positioning plate. A second hydraulic telescopic rod is fixedly connected to the upper surface of the fixing seat.

[0009] Through the above technical solution, the running-in test bench is equipped with a clamping mechanism, which allows the user to move the position of the adjustment plate by rotating the first threaded rod, so as to quickly disassemble and replace the belt, or adjust and replace the pulley to adapt to belts and pulleys of different sizes or types, thereby enhancing the adaptability of the equipment.

[0010] Furthermore, the support base is fixedly connected to the upper surface of the positioning plate on one side, and a first flange is fixedly connected to the outer wall of the drive shaft away from the first pulley;

[0012] Furthermore, the mounting base is fixedly connected to the front end of one side of the upper surface of the base, and the middle part of the outer wall of the first threaded rotating rod is threadedly engaged with the adjusting plate.

[0013] The above technical solution enables users to adjust the position of the adjustment plate on the mounting base by rotating the first threaded rod.

[0014] Furthermore, guide grooves are fixedly connected to both sides of the upper surface of the mounting base, and guide rails are fixedly connected to both sides of the lower surface of the adjustment plate.

[0015] The above technical solution allows the adjustment plate to slide smoothly on the mounting base by setting guide grooves and guide rails.

[0016] Furthermore, the adjusting slide is slidably connected to the upper surface of the positioning plate, and the front and rear ends of the upper surface of the adjusting slide are both threaded with two locking screws;

[0017] The above technical solution enables the locking screw to lock and fix the adjustment slide after the movement is completed.

[0018] Furthermore, a connecting shell is fixedly connected to the other side of the upper surface of the adjusting slide, and a connecting shaft is rotatably connected to the upper end of the outer wall of one side of the connecting shell. A second flange is fixedly connected to the outer walls on both sides of the connecting shaft.

[0020] Furthermore, guide rods are fixedly connected to both sides of the front and rear inner walls of the placement slot, and guide blocks are fixedly connected to both sides of the front and rear outer walls of the locking frame.

[0021] The above technical solution enables the locking frame to slide smoothly up and down within the placement slot by setting guide rods and guide blocks.

[0022] Furthermore, a first ejector pin is fixedly connected to the middle of the outer wall of the drive shaft on the side away from the first pulley, and a second ejector pin is rotatably connected to the output end of the second hydraulic telescopic rod;

[0023] The above technical solution enables the spindle to be clamped and limited on the device by setting a first ejector pin and a second ejector pin.
