Description

Technical Field

[0001] The utility model relates to a bearing load capacity detection device, belonging to the field of bearing detection. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. In the production process of bearings, it is necessary to sample batches of bearings and then measure their load-bearing capacity. In the process of load-bearing capacity detection, it is necessary to apply opposite forces to the inner and outer rings of the bearings. The sizes of the inner and outer rings of bearings of different specifications are different. Therefore, when applying forces to the inner and outer rings of different bearings, it is necessary to use a pressure-applying structure that matches the specifications of the bearings. The versatility is poor, so it is necessary to design a bearing load-bearing capacity detection device suitable for bearings of different specifications and sizes. Utility Model Content

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a bearing load capacity detection device to solve the problems raised in the above-mentioned background technology. The present invention is suitable for the needs of bearing load capacity detection of different specifications and sizes, thereby expanding the scope of application.

[0004] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a bearing load-bearing capacity detection device, including a base, a conical column for limiting the position of the inner ring of the bearing is installed on the upper surface of the base, the conical column is a structure that is narrow at the top and wide at the bottom, a water tank is provided on the upper side of the conical column, the water tank is connected to the base through a connecting guide, two vertically arranged hydraulic cylinders are installed at the bottom of the base, the movable ends of the hydraulic cylinders pass through the base and contact the bottom of the water tank, two U-shaped frames are symmetrically installed at the bottom of the water tank, a pressure plate for overlapping the outer ring of the bearing is inserted in the U-shaped frame, a threaded hole is opened on the lower surface of the U-shaped frame, and a positioning screw for limiting the relative position of the U-shaped frame and the pressure plate is threadedly connected in the threaded hole, an electromagnetic valve for connecting a tap water pipe is installed at the upper position of one side surface of the water tank, and a stop valve for connecting a return water pipeline is installed at the lower position of one side surface of the water tank.

[0005] Furthermore, the guide member includes a support ear, and two symmetrically arranged support ears are installed at the lower position of one side of the water tank. A guide hole penetrating the support ear is opened on the upper surface of the support ear, and a guide rod is inserted in the guide hole. The lower end of the guide rod is connected and fixed to the base.

[0006] Furthermore, two blind holes are provided on the upper surface of the base, and the lower ends of the two guide rods are respectively fixed in the two blind holes.

[0007] Furthermore, a tray is connected and fixed to the movable end of the hydraulic cylinder, and the tray is in contact with the bottom of the water tank.

[0008] Furthermore, an L-shaped seat is connected and fixed to the lower surface of the base, and a plurality of evenly arranged fixing holes are opened on the horizontal portion of the L-shaped seat.

[0009] Furthermore, the vertical portion of the L-shaped seat is connected and fixed with two symmetrically arranged triangular plates, and the triangular plates are connected and fixed to the base.

[0010] Furthermore, a liquid level gauge is installed on one side of the water tank, and the liquid level gauge is arranged vertically.

[0011] Beneficial effects of the utility model:

[0012] 1. Set the bearing sleeve on the tapered column. Because the tapered column is narrow at the top and wide at the bottom, it can meet the needs of different bearing inner ring diameters. Adjust the relative position of the pressure plate and the U-shaped frame so that one end of the pressure plate on the lower side of the water tank overlaps the outer ring of the bearing. Then use the positioning screw to limit the relative position of the pressure plate and the U-shaped frame to meet the needs of holding different bearing outer rings. At this time, the weight of the water tank exerts downward pressure on the outer ring of the bearing, while the inner ring of the bearing does not move downward under the support of the tapered column, so that the inner ring and outer ring of the bearing produce opposite forces.

[0013] 2. After the control solenoid valve is opened, the water in the tap water pipe flows into the water tank, and the weight of the water tank gradually increases, that is, the pressure applied to the outer ring of the bearing gradually increases, realizing stepless adjustment of the pressure applied to the outer ring of the bearing. By observing the reading of the liquid level gauge, the overall weight of the water tank can be calculated, which is convenient for obtaining the size of the pressure applied to the bearing. After opening the stop valve, it is convenient to discharge the water in the water tank.

[0014] 3. Before the bearing sleeve is set on the tapered column, the hydraulic cylinder is controlled to extend, and then the hydraulic cylinder drives the tray to contact the bottom of the water tank, increasing the contact range between the movable end of the hydraulic cylinder and the water tank. The hydraulic cylinder extends to drive the water tank to move upward, and then the distance between the water tank and the base is expanded to provide space for placing the bearing. When the water tank moves, it drives the support ear to move along the guide rod to limit the moving trajectory of the water tank. When one end of the pressure plate is pressed on the outer ring of the bearing, the tray does not contact the bottom of the water tank, so that the weight of the water tank acts completely on the outer ring of the bearing.
