DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0023] Example

[0024] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, Figure 1 Shown is a schematic front view of the shaping assembly in the embodiment; Figure 2 Shown is Figure 1 Schematic cross-sectional view in ; Figure 3 Shown is a schematic diagram of the stator; Figure 4 What is shown is a schematic top view of the shaping cylinder in the embodiment;

[0025] The device includes:

[0026] A workbench 10, comprising a base 11 and a top plate 12;

[0027] The shaping assembly 20 includes a shaping cylinder 21 and a groove 23 provided on the base 11. The internal cavity of the shaping cylinder 21 is aligned and connected to the groove 23. The internal side wall of the shaping cylinder 21 is provided with shaping teeth 22 arranged evenly. The shaping assembly 20 also includes a movable seat movably provided in the internal cavity of the shaping cylinder 21; the movable seat carries the stator 1 placed in the interior of the shaping cylinder 21;

[0028] The driving component 30 , whose output end moves up and down, drives the stator 1 mounted on the movable seat to move downward from the inner cavity of the shaping cylinder 21 .

[0029] After the stator 1 is inserted into the shaping cylinder 21 from the open end thereof, the shaping teeth 22 face the gaps between adjacent segments of the stator 1, and then the stator 1 moves downward under the action of the driving assembly 30 to correct the verticality of both sides of the gap;

[0030] The spacing of the shaping teeth 22 in the shaping cylinder 21 matches the gap between adjacent pieces of the stator 1. The movable seat can move downward under the action of the driving assembly 30, that is, it drives the stator 1 to move downward in the inner cavity of the shaping cylinder 21 until it enters the groove 23. The provision of the groove 23 increases the movement displacement of the stator 1 and enhances the shaping effect of the stator 1.

[0031] like Figure 2 、 Figure 5 As shown, Figure 2 Shown is Figure 1 Schematic cross-sectional view in ; Figure 5 Shown is Figure 2 A schematic diagram of the structure at center A;

[0032] The movable seat includes a movable seat 1 24 and a movable seat 25. The movable seat 1 24 is movably arranged at the opening end of the groove 23 by means of an elastic component 1, and the movable seat 25 is movably arranged at the top end of the movable seat 1 24 by means of an elastic component 2 but does not exceed the opening of the shaping cylinder 21.

[0033] The coordination of elastic component 1 and elastic component 2 can prevent the elastic effect of a certain elastic component from deteriorating after being in a compression-restoration cycle state for a long time, thereby avoiding affecting the resetting of the stator 1 after shaping and making it difficult to remove the stator 1. The corresponding movable seat 1 24 and movable seat 2 25 are coordinated with the elastic component 1 and elastic component 2.

[0034] Elastic component 1 includes a fixed rod 261 vertically disposed within the groove 23 and a collar 263 disposed on the side wall of the bottom end of the movable seat 1 24. The collar 263 corresponds to the fixed rod 261 and is slidably mounted on the outside of the fixed rod 261. A spring 1 262 is also mounted on the outside of the fixed rod 261 between the collar 263 and the bottom wall of the groove 23.

[0035] The fixing rod 261, spring 1 262 and collar 263 are provided to realize elastic connection with the movable seat 1 24, and a limit block is provided at the top of the fixing rod 261 to limit the separation of the collar 263, thereby preventing the movable seat 1 24 from separating.

[0036] The movable seat 1 24 moves downward when receiving pressure from the top, and at the same time causes the collar 263 to compress the spring 1 262 . After the external force is removed, the spring 1 262 returns to its original position, driving the movable seat 1 24 to return to its original position.

[0037] The second elastic component includes connecting rods 271 that are symmetrically arranged and hinged to each other. The upper and lower connecting rods 271 are hinged to the bottom end of the second movable seat 25 and the top end of the first movable seat 24, respectively. The ends of the upper and lower connecting rods 271 on the same side are also hinged to each other. A second spring 272 is also provided between the ends of the left and right connecting rods 271.

[0038] When the movable seat 25 is subjected to downward pressure, the upper and lower connecting rods 271 are driven to move closer to each other, and at the same time the spring 272 is stretched to achieve the downward movement of the movable seat 25. Similarly, after the external force is removed, the spring 272 is reset, thereby driving the connecting rod 271 to reset, that is, the movable seat 25 is reset.

[0039] like Figure 3 、 Figure 5 As shown, Figure 3 The figure shows the stator schematic diagram. Figure 5 Shown is Figure 2 A schematic diagram of the structure at center A;

[0040] A positioning post 251 is also provided on the top of the movable seat 25. The diameter of the positioning post 251 matches the socket of the stator 1.

[0041] The positioning post 251 plays a role in positioning and installing the movable seat 25. When installing, the positioning post 251 is sleeved on the positioning post 251, which is convenient and fast. When taking it out, it is also convenient and fast.

[0042] like Figure 1 、 Figure 2 As shown, Figure 1 Shown is a schematic front view of the shaping assembly in the embodiment; Figure 2 Shown is Figure 1 Schematic cross-sectional view in ;

[0043] The driving assembly 30 includes a hydraulic cylinder 31 and a pressure plate 32. The hydraulic cylinder 31 is arranged at the lower end of the top plate 12 of the workbench 10 and corresponds to the position of the shaping cylinder 21. The pressure plate 32 is arranged on the downward output end of the hydraulic cylinder 31. The diameter of the pressure plate 32 is not greater than the diameter of the inner cavity of the shaping cylinder 21.

[0044] The hydraulic cylinder 31 is started, so that the output end of the hydraulic cylinder 31 drives the pressing plate 32 to push the stator 1 to continuously move downward in the shaping cylinder 21 to achieve shaping.

[0045] Working principle: When using this device to correct the verticality of the gap between adjacent pieces of the stator 1, first insert the stator 1 from the open end of the shaping cylinder 21 onto the movable seat 25, and at the same time make the shaping teeth 22 correspond to the gap between the adjacent pieces of the stator 1, then start the driving component 30, so that the output end of the hydraulic cylinder 31 drives the pressure plate 32 to push the stator 1 and the movable seat to move downward in the shaping cylinder 21 until it can no longer move, and then retract the output end of the hydraulic cylinder 31. At this time, the movable seat 1 24 and the movable seat 2 25 are both reset under the action of the elastic component 1 and the elastic component 2, thereby driving the stator 1 to reset. After resetting, the top end of the stator 1 is in a position extending out of the open end of the shaping cylinder 21, and the stator 1 can be removed.

[0046] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
