[0034] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0035] Please combine Figure 1 and Figure 2 A motor shaft straightening device of this embodiment includes a frame 1. First, an upper slider 5 is slidably installed on the frame 1. A slide groove is provided on the frame 1, and the upper slider 5 can move along the slide groove. In addition, a threaded shaft 6 is rotatably installed on the frame 1. One end of the threaded shaft 6 is connected to a motor, and the threaded shaft 6 runs through the upper slider 5 as a whole. Therefore, when the motor drives the threaded shaft 6 to rotate, the upper slider 5 can be driven to move along the axial direction of the threaded shaft 6. A hydraulic rod 4 is fixedly connected to the bottom of the upper slider 5, and a straightening block 3 is fixedly connected to the bottom of the hydraulic rod 4. The straightening block 3 is driven downward by the hydraulic rod 4 to straighten the shaft.

[0036] In order to facilitate the fixing of the motor shaft to be straightened (hereinafter referred to as the workpiece shaft), a support plate 2 is also fixedly connected to the frame 1. First, in this embodiment, two support plates 2 are provided, and a plurality of limit openings 21 are opened on the support plate 2. The workpiece shaft can be clamped in the limit openings 21 of the two support plates 2.

[0037] In addition, in order to facilitate straightening, auxiliary support wheels 10 are rotatably connected to the outside of the support plate 2, and the auxiliary support wheels 10 are arranged in groups of two. A motor is connected to one side of one of the auxiliary support wheels 10. During installation, it is necessary to control one of the limit openings 21 of the support plate 2 to be located directly below the straightening block 3, and the position of the auxiliary support wheel 10 corresponds to the position of the limit opening 21. When the workpiece axis is ensured to be located in the limit opening 21 on the support plate 2, the workpiece axis is also fitted with the auxiliary support wheel 10. At this time, when the auxiliary support wheel 10 is controlled to rotate, the workpiece axis can also be driven to rotate in the limit opening 21 through friction.

[0038] Please combine Figure 2 and Figure 3 As described above, the support plate 2 is provided with a plurality of limit openings 21 for securing the workpiece axis. In order to improve the straightening efficiency, a pusher 7 is provided on the frame 1, and the pusher 7 is used to quickly transfer the workpiece axis to the processing position directly below the straightening block 3.

[0039] Specifically, the pusher 7 includes a sprocket 71 and a chain belt 77. First, three sprockets 71 are provided, and the three sprockets 71 are connected by the chain belt 77, and one of the sprockets 71 is connected to a motor, and the sprocket 71 is driven to rotate by the motor. The motor is fixedly connected to the frame 1 by screws. The other two sprockets 71 are fixedly connected to short shafts 72, and the short shafts 72 are rotatably connected to the support frame 73 through a plane bearing, and the bottom of the support frame 73 is fixedly welded to the frame 1. As described above, if two support plates 2 are provided, the pusher 7 is arranged between the two support plates 2.

[0040] In addition, the pusher 7 also includes a support plate 74, and two support plates 74 are also provided. Both support plates 74 are located on the inner side of the support plate 2, and a positioning hole 75 corresponding to the limited opening 21 is provided on the support plate 74. A side rocker 76 is fixedly connected to the outer side of the two sprockets 71 that are not connected to the motor. The side rocker 76 is in a "Z" shape as a whole, and the other end is rotatably connected to the support plate 74. Therefore, when the motor drives one of the sprockets 71 to rotate, the three sprockets 71 rotate with the cooperation of the chain belt 77. When the sprocket 71 drives the short shaft 72 to rotate together, the side rocker 76 will also rotate with the short shaft 72 as the axis. At the same time, it drives the support plate 74 to move together.

[0041] When the side rocker 76 in the figure rotates clockwise, the support plate 74 lifts the workpiece shaft during the movement, and the workpiece shaft is stuck in the positioning hole 75 and separated from the limit hole 21. As the support plate 74 continues to move, when the height of the support plate 74 is lower than the support plate 2, the workpiece shaft will be transferred to the next limit hole 21 close to the straightening block 3. Repeating the operation can gradually transfer the workpiece shaft to the corresponding limit hole 21 directly below the straightening block 3, that is, the processing position. In this way, the purpose of fast and automatic loading is achieved.

[0042] Please combine Figure 4 and Figure 5 In order to further reduce the number of staff operations and achieve the purpose of fast and automatic loading, a discharge box 8 is provided at one end of the support plate 2, and the workpiece shaft can be stored in the discharge box 8. The discharge box 8 is fixedly mounted on the frame 1, and one end of the discharge box 8 fits the limit opening 21 on the support plate 2, and the discharge box 8 is tiltedly installed, so that the workpiece shaft in the discharge box 8 will roll down under the action of gravity and automatically enter the limit opening 21 on the support plate 2.

[0043] In order to control the workpiece axes to move out of the discharge box 8 one by one, a discharge mechanism 9 is provided at the bottom of the discharge box 8. Specifically, the discharge mechanism 9 includes a discharge shaft 91. First, a discharge rack (not marked in the figure) is rotatably connected to the outside of the discharge shaft 91, and the discharge rack is fixedly connected to the bottom of the discharge box 8. In addition, two blocking pieces 92 are also included. The two blocking pieces 92 are fixedly connected to the discharge shaft 91, and the two blocking pieces 92 are installed ninety degrees apart. A hole is provided at the bottom of the discharge box 8 so that the blocking piece 92 can enter the inside of the discharge box 8 during the rotation process. The two blocking pieces 92 are ninety degrees apart.

[0044] Reference Figure 5 As shown, the one close to the outlet of the discharge box 8 is defined as the blocking piece 92 (A), and the other is defined as the blocking piece 92 (B). The one closest to the outlet of the discharge box 8 is defined as the first workpiece axis, and the next closest is defined as the second workpiece axis.

[0045] In the first step, the blocking piece 92 (A) is located in the discharge box 8 to block the first workpiece shaft so that the workpiece shafts in the discharge box 8 cannot fall down.

[0046] In the second step, when the motor drives the discharge shaft 91 to rotate, the blocking piece 92 (B) enters the discharge box 8 and is located between the first and second workpiece shafts to block the second workpiece shaft. When the discharge shaft 91 continues to rotate and the blocking piece 92 (A) is completely moved out of the discharge box 8, the first workpiece shaft automatically rolls down into the limit opening 21 on the support plate 2 under the action of gravity.

[0047] In the third step, the discharge shaft 91 continues to rotate, and the blocking piece 92 (A) re-enters the discharge box 8, and the blocking piece 92 (B) moves out. At this time, since the first workpiece shaft moves out, the second workpiece shaft automatically moves to the position of the first workpiece shaft. That is, the initial position is restored ( Figure 5 status shown).

[0048] The rotation speeds of the discharge shaft 91 and the sprocket 71 are controlled so that after the workpiece shaft falls from the discharge box 8 onto the support plate 2 , the support plate 74 starts to transfer the workpiece shaft so that the workpiece shaft is close to the straightening block 3 .

[0049] The implementation process and principle of a motor shaft straightening device in the embodiment of the present application are as follows:

[0050] (I): First, during the continuous rotation of the discharge shaft 91, the two blocking pieces 92 will block the workpiece shaft closest to the outlet of the discharge box 8 in turn. At the same time, the discharge box 8 is installed tilted, and with the effect of gravity, the workpiece shafts in the discharge box 8 can automatically roll out of the discharge box 8 one by one and automatically fall into the limit opening 21 at the end of the support plate 2.

[0051] (ii) The motor cooperates with the chain belt 77 to drive the sprocket 71 to rotate, and the sprocket 71 drives the short shaft 72, the side rocker 76 and the support plate 74 to move together. During the movement, the support plate 74 first exceeds the support plate 2 in height, so that the workpiece shaft can be lifted and the workpiece shaft is separated from the support plate 2 (limiting opening 21);

[0052] Then, as the support plate 74 continues to move, when the support plate 74 is lower than the support plate 2, the workpiece axis will be transferred to the next limit opening 21 near the straightening block 3. Repeating the operation, the workpiece axis can be gradually transferred from one end of the support plate 2 to the corresponding limit opening 21 directly below the straightening block 3.

[0053] (III): The position of the straightening block 3 is adjusted by moving the upper slider 5, and the workpiece shaft is driven to rotate by controlling the auxiliary support wheel 10. Then, the straightening block 3 is controlled to move downward, press down on the workpiece shaft, and adjust the workpiece shaft axis to coincide with the geometric center.

[0054] Therefore, in summary, the discharge box 8 can store multiple workpiece shafts at the same time, and the support plate 2 is also provided with multiple limit openings 21 for placing the workpiece shafts, so that during the continuous operation of the discharge box 8 and the pusher 7, rapid automatic loading can be achieved. Improve the straightening efficiency. And the support plate 2 is provided with an arc surface at one end of the discharge box 8. It is convenient for the straightened workpiece shaft to roll directly along the arc surface to the corresponding collection device.

[0055] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
