Description

Technical Field

[0001] This utility model relates to the field of motor shaft production, and more specifically, to a straightening device for motor shaft production and processing. Background Technology

[0002] The motor shaft, as a core component of a motor, bears multiple functions including support, torque transmission, and positioning. Its strength and rigidity directly affect the stable operation of the motor. Motor shafts can be divided into two main categories: smooth shafts and stepped shafts. Smooth shafts, as the name suggests, have no steps on their surface and are often made of cold-drawn round steel; they are sometimes used in micro motors. Stepped shafts, on the other hand, have multiple outer diameters, providing convenience and stability for the installation of different components, and are therefore widely used in most motors.

[0003] During the production process, some defective motor shafts may appear, including those with surface dents or overall bending. For bent motor shafts, straightening devices are needed for straightening. Traditional straightening equipment usually requires workers to align the bent area with the clamping part of the straightening equipment to achieve compression straightening. This requires workers to accurately locate the straightening area before operating, which is relatively cumbersome and troublesome.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0020] The utility model will now be further described with reference to the accompanying drawings and specific embodiments:

[0021] Please see Figure 1-3 According to an embodiment of the present invention, a straightening device for manufacturing and processing motor shafts includes a worktable 1. Support legs 2 are fixedly installed at the bottom corners of the worktable 1. Several support platforms 3 for supporting workpieces 100 are installed at the top center of the worktable 1. Stands 4 are fixedly installed at the top of both ends of the worktable 1. An extension plate 5 is fixedly installed at the top of the stand 4 facing directly above the worktable 1. A top plate 6 is fixedly installed at the bottom between the extension plates 5. A first slide rail 7 is symmetrically installed at the bottom of the top plate 6 along its center. The first slide rail 7 is arranged along the length of the worktable 1. A first slide block 11 is slidably installed on the first slide rail 7. A transverse sliding plate 12 is fixedly installed at the bottom of the first slide block 11. A mounting base 15 is fixedly installed at the bottom center of the transverse sliding plate 12. A hydraulic cylinder 16 is fixedly installed at the bottom of the mounting base 15. A straightening block 17 is fixedly installed at the end of the output shaft of the hydraulic cylinder 16.

[0022] Place the workpiece 100 on the support platform 3, then adjust the position of the transverse plate 12 at the bottom of the top plate 6 until the straightening block 17 is aligned with the position on the workpiece 100 that needs to be straightened. Then start the hydraulic cylinder 16, which will drive the straightening block 17 to move toward the workpiece 100, thereby realizing the straightening operation of the workpiece 100.

[0023] An adjusting motor 8 is installed at one bottom end of the top plate 6. A lead screw 9 is fixedly installed at the output shaft end of the adjusting motor 8. An end block 10 is fixedly installed at the other bottom end of the top plate 6. The end of the lead screw 9 away from the adjusting motor 8 is rotatably mounted on the end block 10. A fixing block 13 is fixedly installed on the top of the transverse plate 12. A threaded sleeve 14 is fixedly installed on the fixing block 13 and screwed to the outside of the lead screw 9. When the adjusting motor 8 is started, it drives the lead screw 9 to rotate. When the lead screw 9 rotates, it drives the fixing block 13 to move through the threaded sleeve 14. The movement of the fixing block 13 drives the transverse plate 12 to move synchronously, thereby realizing the position adjustment of the hydraulic cylinder 16 and the straightening block 17.

[0024] Please see Figure 4-5 The top of the workbench 1 is symmetrically equipped with a second slide rail 18 along the center. The second slide rail 18 is arranged along the length direction of the workbench 1. The top of the second slide rail 18 is symmetrically slidably equipped with a second slide block 19. The top of the second slide block 19 on the same side is fixedly equipped with a movable plate 20. A vertical frame 21 is fixedly equipped on one side of the top of the movable plate 20. An extension frame 22 facing the middle of the movable plate 20 is fixedly equipped on the top of the vertical frame 21. A rotary motor 23 is installed at the end of the extension frame 22 on one side. A ejector pin 24 is fixedly installed at the end of the output shaft of the rotary motor 23. A rotating plate 25 facing the ejector pin 24 is rotatably installed at the end of the extension frame 22 on the other side. The workpiece 100 is placed on the support platform 3 between the rotating plate 25 and the ejector pin 24. Then, the moving plate 20 is controlled to move. The moving plate 20 will drive the ejector pin 24 and the rotating plate 25 to press the end of the workpiece 100, thereby ensuring the stability of the straightening block 17 when straightening the workpiece 100. The rotary motor 23 can also drive the workpiece 100 to rotate through the ejector pin 24 and the rotating plate 25, so that the area to be straightened can be flipped and adjusted.

[0025] A bidirectional cylinder 26 is fixedly installed at the bottom center of the workbench 1. Telescopic shafts 27 are installed at both ends of the bidirectional cylinder 26. A moving block 28 is fixedly installed at the end of the telescopic shaft 27 away from the bidirectional cylinder 26. A connecting frame 29 is fixedly installed on the top of the moving block 28. A strip hole 30 is also symmetrically opened along the center on the workbench 1. The top of the connecting frame 29 passes through the strip hole 30 and is fixedly installed at the bottom of the moving plate 20.

[0026] The bidirectional cylinder 26 is activated, which can drive the two moving blocks 28 to move closer or further apart, and then drive the moving plate 20 to move synchronously through the connecting frame 29, so as to achieve the clamping and positioning of workpieces 100 of different lengths.

[0027] Through the above-described solution of this utility model, the structure of this utility model is simple and easy to use. The straightening block 17 can be moved toward the worktable 1 by the hydraulic cylinder 16, thereby straightening the workpiece 100 on the support table 3. Moreover, the transverse plate 12 can also be moved and adjusted along the length direction of the first slide rail 7, thereby changing the horizontal position of the straightening block 17, which is convenient for straightening different areas on the workpiece 100. At the same time, the ejector pin 24 and the rotating plate 25 can clamp the workpiece 100, and the ejector pin 24 can be rotated by the rotary motor 23, thereby adjusting the rotation of the workpiece 100, which is convenient for flipping the straightening area.
