[0018] Beneficial effects

[0019] This invention provides a motor shaft straightening device. Compared with the prior art, it has the following advantages:

[0020] 1. This technical solution uses slide rails, slide rods, and lifting components to allow the motor shaft to be placed on top of the support seats on both sides. Then, by moving the support seats upward, the axis of the motor shaft can be aligned with the pins on both sides. This makes it easy to fix the support seats at the required height and clamp the motor shaft by aligning it with the pins on both sides, thus improving the feeding efficiency of the motor shaft on the straightening device.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] See Figures 1-4 This utility model provides the following two technical solutions:

[0029] First embodiment: A motor shaft straightening device includes a worktable 1. The top of the worktable 1 is provided with a clamping assembly for clamping the motor shaft. The clamping assembly includes an electric guide rail 2 provided on the right side of the top of the worktable 1. The output end of the electric guide rail 2 and the left side of the top of the worktable 1 are both provided with connecting seats 3. The electric guide rail 2 is used to drive the connecting seat 3 at the right end to move laterally so as to clamp motor shafts of different lengths. A sliding seat 4 is slidably connected to the connecting seat 3, and a spring is provided between the bottom of the sliding seat 4 and the connecting seat 3. The opposite sides of the two connecting seats 3 are connected with pins 5 through bearings. The pins 5 on both sides are used to clamp the motor shaft. A reduction motor 6 is provided on the right connecting seat 3 with an output shaft connected to the right pin 5. The reduction motor 6 drives the right pin 5 to rotate, so that the motor shaft rotates accordingly.

[0030] The top of the worktable 1 is equipped with an electric guide rail 2 7. The output end of the electric guide rail 2 7 is equipped with a lifting and pressing component 8, which is used to drive the lifting and pressing component 8 to move laterally. The lifting and pressing component 8 is used to press down the motor shaft. When the lifting and pressing component 8 presses down the motor shaft, the motor shaft can drive the sliding seat 4 to slide down in the connecting seat 3 through the two side pins 5, which can compress the spring until the motor shaft contacts the support seat 13. The support seat 13 supports the motor shaft. The lifting and pressing component 8 presses the bent part of the motor shaft, which can apply a reaction force to the motor shaft to straighten it.

[0031] This device is equipped with a shaft detector for detecting the degree of bending of the motor shaft. This is existing technology and will not be described in detail here.

[0032] The top of the workbench 1 is provided with two bases 9, and an electric telescopic rod 10 is connected between the two bases 9. The left base 9 is fixed on the workbench 1, and the right base 9 is slidably connected to the workbench 1, so that the position of the right support 13 can be adjusted to accommodate motor shafts of different lengths.

[0033] Both sides of the base 9 are provided with slide rails 11, and slide rods 12 are slidably connected on the slide rails 11. The slide rods 12 are set on the support base 13. Both of the front slide rails 11 are provided with fixing components for fixing the front slide rods 12.

[0034] Both sides of the base 9 are equipped with lifting components for pushing the support base 13 to rise;

[0035] Both sides of the base 9 are equipped with detection components to detect whether the lifting assembly has been reset.

[0036] The fixing assembly includes a fixing rod 14 arranged in the front-rear direction. The fixing rod 14 is inserted into the front slide rod 12, and the front section of the fixing rod 14 passes through the front slide rail 11 and is connected to the mounting block 15. The mounting block 15 is provided with a return spring 16 connected to the front slide rail 11. The return spring 16 applies a pulling force to the mounting block 15, so that the fixing rod 14 can be stably inserted into the slide rod 12.

[0037] To facilitate the simultaneous pulling of the two mounting blocks 15, a sleeve rod 18 is provided on the left mounting block 15. An inner rod 19 connected to the right mounting block 15 is slidably connected to the sleeve rod 18. When the right base 9 moves laterally, the inner rod 19 can slide laterally on the sleeve rod 18. Similarly, by simply pulling the sleeve rod 18 forward with one hand, the inner rod 19 can be moved forward, thereby moving the mounting blocks 15 on both sides forward.

[0038] The lifting assembly includes two electric push rods 20, both mounted on the base 9. Each electric push rod 20 has a push plate 21 at its output end. To facilitate more stable lifting of the support base 13, a positioning groove is provided on the top of the push plate 21, and positioning posts 22 matching the positioning groove are provided on both sides of the bottom of the support base 13. The push plate 21 is located below the support base 13.

[0039] In order to detect whether the push plate 21 has returned to its original position after moving downward, i.e. whether it has moved away from the support base 13, the detection component includes a mounting bracket 23 set on the slide rail 11. An industrial camera 24 is set on the mounting bracket 23 opposite to the two push plates 21. An alarm 25 is set on the top of the mounting bracket 23. A control host 26 is set on the workbench 1. The industrial camera 24 is electrically connected to the control host 26, and the control host 26 is electrically connected to the alarm 25.

[0040] The second embodiment differs from the first embodiment in that: a groove is formed at the rear of the fixing rod 14, and a rotating shaft is connected to the groove via a bearing, and a rotating wheel 17 is provided on the rotating shaft, with the rear end of the rotating wheel 17 extending out of the groove.

[0041] The rotating wheel 17 is provided so that when the fixed rod 14 is pulled forward, the rotating wheel 17 moves forward with it. When the fixed rod 14 is released, the support seat 13 moves upward. At this time, the front slide rod 12 and the rotating wheel 17 roll against each other, which can reduce frictional resistance and facilitate the lifting and lowering of the support seat 13.

[0042] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0043] In use, place the motor shaft on top of the two side support seats 13, then pull the pressure sleeve rod 18 forward so that the two side fixing rods 14 are both away from the front sliding rod 12, thus removing the fixation of the two side support seats 13. The electric push rod 20 can then drive the push plate 21 to contact the support seat 13 and lift the support seat 13 until the axis of the motor shaft is aligned with the two side ejector pins 5. This allows the right ejector pin 5 to move to the left to clamp the motor shaft, facilitating quick alignment by clamping the motor shaft with the two side ejector pins 5. Then, shorten and reset the electric push rod 20 to move the support seat 13 downward. Resetting allows the sleeve rod 18 to be released, enabling the fixing rod 14 to be re-inserted onto the front slide rod 12, thus fixing the support base 13. When the push plate 21 of the electric push rod 20 moves into the recognition range of the industrial camera 24, the alarm 25 sounds, indicating that the push plate 21 of the electric push rod 20 has been successfully reset and the alarm 25 can be turned off. At this time, the push plate 21 does not contact the support base 13, so when the motor shaft is pressed downward by the lifting and pressing assembly 8, the support base 13 bears the pressure, but the electric push rod 20 does not bear the pressure, thereby improving the service life of the electric push rod 20.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
