Description

Technical Field

[0001] The utility model relates to the technical field of shaft workpiece processing equipment, in particular to a motor shaft keyway processing device. Background Technique

[0002] As a key component of the drive system, the machining accuracy of the motor shaft directly affects the performance of the drive system. Especially when machining a keyway on the motor shaft, it is required that the position of the keyway must be accurate. Therefore, during the machining process, a motor shaft keyway processing device is often used.

[0003] In the prior art, for example, a Chinese patent application (publication number: CN118268635A) discloses a motor shaft keyway processing machine, the structure of which includes a vertical milling machine. A workbench is movably arranged on the vertical milling machine, two rollers are arranged in parallel on the workbench, and a plurality of mounting grooves are also arranged on the workbench. A fixator is arranged on the mounting groove. It also includes a laser locator and a labeling machine. The laser locator and the labeling machine are both installed on the workbench, and the labeling height of the labeling machine is the same as the laser height of the laser locator. When the positioning marks on the workpiece of the laser locator and the labeling machine are aligned, the vertical milling machine starts to work. Through the cooperation of the laser locator and the labeling machine, it is ensured that the keyways at both ends are on the same axis, improving the machining accuracy. Through the cooperation of the transverse movement mechanism and the longitudinal movement mechanism, it can meet the machining requirements of motor shafts with different lengths and shapes.

[0004] However, during the use of the processing equipment disclosed in the above prior art, although it can ensure that the keyways at both ends are on the same axis through the cooperation of the set laser locator and the labeling machine, improving the machining accuracy, and can meet the machining requirements of motor shafts with different lengths and shapes through the cooperation of the transverse movement mechanism and the longitudinal movement mechanism, in actual application, the processing equipment only realizes the fixation of the motor shaft through the cooperation of the set connecting seat, stud and nut. During the fixation process, the tightening degree of the stud and the nut cannot be guaranteed, so the fixation effect on the motor shaft cannot be guaranteed. In addition, after the machining of the side of the motor shaft close to the bottom of the processing equipment is completed, it is necessary to first release the clamping state, turn the motor shaft over, and then operate the clamping mechanism to fix it, which has the problem of cumbersome operation.

[0027] Example 2: Please refer to Figure 3 - Figure 7, and combined with Example 1, it is further obtained that the adjustment and fixing mechanism 4 includes a flipping component 41 that can flip the motor shaft body 5, and a first mounting plate 411 is provided in the flipping component 41, and the first mounting plate 411 is provided inside the workbench 34, and a motor base 412 is fixedly installed on the outside of the first mounting plate 411, and a first motor 413 is fixedly installed on the inside of the motor base 412, and a toggle disk 414 is fixedly installed on the output shaft of the first motor 413, and a connecting column 415 is fixedly installed on the outside of the toggle disk 414, and a mounting column 416 is rotatably installed inside the first mounting plate 411, and a connecting frame 417 is fixedly installed on the outside of the mounting column 416, and a sub-rotating disk 418 is fixedly installed on the outside of the connecting frame 417 close to the toggle disk 414, so as to facilitate intermittent rotation of the clamped motor shaft body 5 without changing the clamping state, so as to perform keyway processing on different areas.

[0028] Furthermore, a sub-rotation groove is provided inside the sub-rotation disk 418 , and the connecting column 415 and the dial 414 are in contact with the sub-rotation groove, so as to facilitate the intermittent flipping of the connecting frame 417 .

[0029] Furthermore, the adjustment and fixing mechanism 4 also includes a fixing component 42 that can clamp motor shaft bodies 5 of different sizes and specifications.
