[0030] Unless otherwise defined, the up, down, left, right, front, back, inner and outer directions involved herein are based on the up, down, left, right, front, back, inner and outer directions shown in the figures of the present utility model, and are hereby explained together.

[0031] This embodiment provides a stator dovetail rib installation and straightening tool as Figures 1 to 3 shown, which includes: a flat H-shaped straightening support 1, a straightening and correcting assembly 6, and a supporting and synchronous blanking assembly 7.

[0032] In this embodiment, the flat H-shaped straightening support 1 is installed on the workbench of a vertical hydraulic stamping machine. The flat H-shaped straightening support 1 includes a straightening and correcting area 2 provided at the upper part and a supporting, bearing and blanking area 3 provided at the lower part;

[0033] In this embodiment, the straightening and correcting assembly 6 is arranged in the straightening and correcting area 2 and slides on the top surface of the flat H-shaped straightening support 1. The straightening and correcting assembly 6 includes a U-shaped straightening card plate 9 that is reversely clamped on the flat H-shaped straightening support 1 and a first electric push-pull rod 10 installed between the back surface of the U-shaped straightening card plate 9 and the inner wall of the flat H-shaped straightening support 1; the U-shaped straightening card plate 9 is used in cooperation with the first electric push-pull rod 10, and its shape design helps to accurately clamp the stator dovetail rib part 8 so as to apply uniform pressure for straightening. The first electric push-pull rod 10 pushes the U-shaped straightening card plate 9 to move along the surface of the stator dovetail rib part 8, thereby discovering and correcting the bending points therein.

[0034] In this embodiment, the support synchronous blanking component 7 is arranged in the support bearing blanking area 3 and slides on the bottom surface of the flat H-shaped straightening support 1. The support synchronous blanking component 7 includes a T-shaped support beam 11 and a blanking slide plate 19 fixed to the outer wall of the T-shaped support beam 11. The T-shaped support beam 11 provides a stable support surface for the stator dovetail rib component 8 and at the same time allows it to move back and forth through the second electric push-pull rod 18 to assist in completing the blanking process.

[0035] In this embodiment, a positioning rib straightening card slot 12 is formed in the middle of the top surface of the flat H-shaped straightening support 1. The stator dovetail rib component 8 is fitted in the positioning rib straightening card slot 12. The positioning rib straightening card slot 12 provides an accurate position reference for the stator dovetail rib component 8 to ensure that each straightening can be carried out according to the same standard. The inside of the U-shaped straightening card plate 9 is set as a straightening flush part 15. The straightening flush part 15 is in sliding friction contact with the top surface of the flat H-shaped straightening support 1. The straightening flush part 15 is a part of the U-shaped straightening card plate 9 and directly contacts the stator dovetail rib component 8 to determine the bending part through frictional contact. The first electric push-pull rod 10 pushes and pulls the U-shaped straightening card plate 9 to slide on the top surface of the stator dovetail rib component 8 to detect the bending position of the stator dovetail rib component 8 and presses down on the stator dovetail rib component 8 through a vertical hydraulic stamping machine to straighten it. The T-shaped support beam 11 supports and bears the stator dovetail rib component 8 under the flat H-shaped straightening support 1.

[0036] In this embodiment, the bent ends at both ends of the U-shaped straightening card plate 9 slide frictionally on the outer walls on both sides of the flat H-shaped straightening support 1 and are connected through a positioning component.

[0037] In this embodiment, positioning ear plates 13 are symmetrically welded on the outer walls on both sides of the flat H-shaped straightening support 1. A first positioning rod 14 is welded between adjacent positioning ear plates 13. The bent ends at both ends of the U-shaped straightening card plate 9 are penetrated and positioned by the adjacent first positioning rods 14. The first positioning rod 14 penetrates through the bent end of the U-shaped straightening card plate 9 to ensure that the U-shaped straightening card plate 9 does not deviate from the track.

[0038] In this embodiment, a control wire box 4 is fixedly connected to the lower part of one side outer wall of the flat H-shaped straightening support 1. The top surface of the control wire box 4 has a display screen and control buttons respectively.

[0039] In this embodiment, mounting side plates 5 are integrally connected to the outer walls on both sides of the flat H-shaped straightening support 1 and the lower part of the outer wall of the control wire box 4. The mounting side plates 5 are fixedly connected to the workbench of the vertical hydraulic stamping machine through bolts. Ensure that the whole tool is firmly installed on the vertical hydraulic stamping machine to prevent it from moving during use.

[0040] In this embodiment, a second positioning rod 16 for passing through the T-shaped support beam 11 is symmetrically welded between the inner walls on both sides of the flat H-shaped straightening support 1, so that the T-shaped support beam 11 is positioned and moved on the two second positioning rods 16.

[0041] In this embodiment, a second electric push-pull rod 18 is installed on the inner wall of one side of the lower part of the flat H-shaped straightening support 1, and the telescopic free end of the second electric push-pull rod 18 is connected to the outer wall of the T-shaped support beam 11.

[0042] In this embodiment, an electromagnet block 17 is embedded in the top surface of the T-shaped support beam 11, and the electromagnet block 17 is magnetically attracted to the stator dovetail rib member 8. The electromagnet block 17 is embedded in the T-shaped support beam 11, and the stator dovetail rib member 8 is attracted by magnetic force to increase its stability during straightening.

[0043] In this embodiment, the inside of the blanking slide plate 19 has a blanking chute 20 for carrying the blanking and sliding of the stator dovetail rib member 8. When the straightening of the stator dovetail rib member 8 is completed, as the T-shaped support beam 11 moves backward to a suitable position, the stator dovetail rib member 8 can slide down along the blanking chute 20 to the collection place.

[0044] In this embodiment, after the stator dovetail rib member 8 is corrected and straightened, the second electric push-pull rod 18 drives the T-shaped support beam 11 to retract to its original position, so that the blanking slide plate 19 is pulled to directly below the positioning rib straightening slot 12 for the blanking and sliding of the stator dovetail rib member 8.

[0045] Working principle:

[0046] For this stator dovetail rib installation and straightening tool, the flat H-shaped straightening support 1 is installed on the workbench of the vertical hydraulic stamping machine, and it is ensured that it is firmly fixed through the installation side plate 5. Necessary parameters are set through the control wire box 4, such as the action speed of the electric push-pull rod, the magnetic force intensity of the electromagnet block 17, etc. The operator places the stator dovetail rib member 8 to be straightened into the positioning rib straightening slot 12. This slot ensures that the stator dovetail rib member 8 is accurately positioned in the straightening area 2 and is ready to receive the straightening treatment.

[0047] The electromagnet block 17 on the T-shaped support beam 11 is activated to attract and stabilize the stator dove-tail rib member 8, preventing unnecessary movement during the straightening process. The first electric push-pull rod 10 pushes the U-shaped straightening clamping plate 9 to slide along the surface of the stator dove-tail rib member 8, and the straightening flush portion 15 is used to contact the stator dove-tail rib member 8, thereby detecting any bent or uneven positions. Once the U-shaped straightening clamping plate 9 identifies a bent point, the bent convex point hinders the continuous movement of the U-shaped straightening clamping plate 9. At this time, manually close the forward movement of the first electric push-pull rod 10 and mark the bent point with a marker pen. At this time, the first electric push-pull rod 10 pulls the U-shaped straightening clamping plate 9 back to its original position, and the vertical hydraulic stamping machine applies a downward pressure to the bent point to correct the deformation of the stator dove-tail rib member 8. During this process, the T-shaped support beam 11 continuously provides stable support, and the second positioning rod 16 ensures that the T-shaped support beam 11 does not deviate from the correct position.

[0048] When the straightening of the stator dove-tail rib member 8 is completed, the electromagnet block 17 releases the stator dove-tail rib member 8, and the second electric push-pull rod 18 acts to pull the T-shaped support beam 11 and the blanking slide plate 19 backward until the blanking slide plate 19 is directly below the positioning rib straightening slot 12. Then the stator dove-tail rib member 8 falls into the blanking chute 20 and automatically slides down along the inclined plane to the collection area.

[0049] The entire device resets to prepare for the straightening of the next stator dove-tail rib member 8. Through such a continuous operation process, the straightening task of the stator dove-tail rib member 8 can be efficiently processed in batches.
