Description

Technical Field

[0001] The utility model relates to the technical field of water pump bearing detection, in particular to an elasticity measuring device for a high-sealing water pump bearing. 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. Usually, due to the characteristics of rolling bearings' own movement, their friction is much smaller than that of sliding bearings, which can reduce the power consumption in friction resistance, thus achieving significant energy-saving effects. The water pump bearings are small in size and installed at the connection part, which fully reflects their role. The bearings are designed to eliminate axial movement, bear axial loads, and reduce end face friction.

[0003] The existing equipment for testing the elasticity of water pump bearings requires manual work to fix the water pump bearings on a workbench by bolts, which makes installation and removal of the water pump bearings extremely troublesome, time-consuming and labor-intensive, and reduces the testing efficiency of the water pump bearings. Utility Model Content

[0004] The utility model aims to solve the problems existing in the background technology and proposes an elasticity measuring device for a high-sealing water pump bearing.

[0005] To achieve this purpose, the utility model adopts the following technical scheme: a device for measuring the elasticity of a high-sealed water pump bearing, comprising a workbench, on the left and right inner walls of the workbench are respectively fixedly mounted bearing blocks and a servo motor, the output end of the servo motor is fixedly connected with a bidirectional lead screw, and the end of the bidirectional lead screw away from the servo motor is rotatably connected to the bearing block, the front and rear inner walls of the workbench are fixedly mounted with sliding rods, the outer peripheries of the bidirectional lead screw and the sliding rod are symmetrically sleeved with two moving blocks, the tops of the moving blocks are fixedly connected with connecting blocks, the top of the workbench is provided with a long slot, the connecting blocks all penetrate the long slot and are fixedly connected with clamping blocks, and the top of the workbench is fixedly mounted with a detection mechanism for detecting the elasticity of the water pump bearing.

[0006] Preferably, the detection mechanism comprises two vertical plates fixedly mounted on the top of the workbench, a top plate is fixedly mounted on the top of the vertical plates, and a cylinder is fixedly mounted on the top of the top plate.

[0007] Preferably, the telescopic shaft of the cylinder passes through the top plate and is fixedly connected with a detection element.

[0008] Preferably, a positioning column is fixedly installed on the top of the workbench, and the positioning column is located directly below the detection element.

[0009] Preferably, arc-shaped grooves are provided on the opposite sides of the clamping blocks, and arc-shaped rubber pads are fixedly installed in the arc-shaped grooves.

[0010] Preferably, the moving blocks are provided with threaded holes and sliding holes, which match the bidirectional screw rod and the sliding rod respectively.

[0011] The beneficial effects of the utility model are as follows: when using the device, first insert the inner ring of the water pump bearing on the positioning column, then start the servo motor to drive the bidirectional lead screw to rotate on the bearing block, and the two moving blocks will synchronously move closer to each other on the periphery of the bidirectional lead screw and the sliding rod, so that the moving block drives the clamping block to move closer to each other through the connecting block fixedly connected to the top thereof, until the arc-shaped rubber pad fixedly installed in the arc-shaped groove of the clamping block completely clamps the water pump bearing, and finally start the cylinder to drive the detection element to descend to a suitable height to detect the water pump bearing, and when the detection is completed, start the servo motor to drive the bidirectional lead screw to rotate in the opposite direction, so that the clamping block releases the clamping of the water pump bearing, and the water pump bearing can be taken out, so that the device can automatically clamp, fix and release the water pump bearing, thereby increasing the detection efficiency, and can also automatically control and adjust the distance between the clamping block and the water pump bearing, thereby increasing the detection effect.
