Description

Technical Field

[0001] This utility model relates to the field of shaft measuring machine technology, and in particular to a rotating mechanism for shaft measuring machine. Background Technology

[0002] A shaft is a cylindrical object that passes through the center of a bearing, wheel, or gear, although some are square. A shaft is a mechanical part that supports rotating parts and rotates with them to transmit motion, torque, or bending moment. It is generally a round metal rod, and different sections can have different diameters. Rotating parts in a machine are mounted on shafts, and a measuring machine is typically used to measure the shaft's pressure resistance.

[0003] When using a measuring machine to measure the pressure resistance of a shaft, the shaft is usually pressed by a pressure roller, and the shaft is observed to see if it bends. This allows for the measurement of the shaft's pressure resistance. At the same time, it is usually necessary to move the pressure roller so that the pressure resistance at different positions of the shaft can be measured. However, during the measurement process, the moving mechanism cannot drive the shaft to rotate synchronously, which makes it impossible to measure the pressure resistance at different angles of the shaft, which is not conducive to the measurement of the shaft.

The bottom of the push plate 8 and one end of the spring 10 are fixedly installed to facilitate the lifting and lowering of the spring 10. The spring 10 is limited by the telescopic rod 9 to make the spring 10 more stable. A pressure measuring mechanism is provided at one end of the spring 10. The pressure measuring mechanism includes a mounting frame 11 fixedly installed at one end of the spring 10. A rotating rod 12 is rotatably installed on the inner wall of the mounting frame 11.

[0021] Specifically, a clamping mechanism is provided on one side of the mounting plate 18. The clamping mechanism includes a second electric push rod 19 fixedly installed on one side of the mounting plate 18. A clamping plate 20 is fixedly installed at the output end of the second electric push rod 19 to facilitate clamping the shaft through the clamping plate 20. There are two sets of the second electric push rod 19 and the clamping plate 20, which are arranged symmetrically. A limiting mechanism is provided on the inner wall of the U-shaped plate 2.

The first electric push rod 7 drives the push plate 8 to descend, and the push plate 8 drives the pressure roller 13 to descend, allowing the shaft to be pressure-tested by the spring 10 and the pressure roller 13. At the same time, the first electric push rod 7 drives the spring 10 to rise and fall, allowing adjustment of the spring 10's clamping force for measurement at different pressures. The motor 3 drives the reciprocating screw 4 to rotate, which in turn drives the moving block 5 to move back and forth, and the moving block 5 drives the mounting plate 6. The mounting plate 6 reciprocates, driving the pressure roller 13 to reciprocate, allowing for pressure resistance measurements at different positions of the shaft. Simultaneously, the reciprocating screw 4 drives the first pulley 14 to rotate, which in turn drives the synchronous belt 15 to rotate. The synchronous belt 15 then drives the second pulley 16 to rotate, which in turn drives the rotating rod 17 to rotate. The rotating rod 17 then drives the mounting plate 18 to rotate, which in turn drives the shaft to rotate. This allows for the measurement of different angles of the shaft via the pressure roller 13. The moving mechanism can rotate the shaft while driving the pressure roller 13, facilitating comprehensive pressure resistance measurements of the shaft. The structure is simple and easy to use.
