The first clamping plate 51 and the second clamping plate 52 are used for clamping the iron core, and the locking assembly 6 is used to lock and fix the first clamping plate 51 and the second clamping plate 52 to the placement table 4; the driving device 7 includes a first fixed seat 71, a second fixed seat 72, and a linkage cylinder 73; the first fixed seat 71 is installed on the top surface of the base 1, the second fixed seat 72 is installed on the flipping seat 3, one end of the linkage cylinder 73 is hinged to the first fixed seat 71, and the other end of the linkage cylinder 73 is hinged to the second fixed seat 72.In this embodiment, the number of the first fixing seats 71, the second fixing seats 72 and the linkage cylinders 73 is two respectively. The two first fixing seats 71 are respectively installed on the top surfaces of the left and right sides of the base 1, the two second fixing seats 72 are respectively installed on the bottom surfaces of the left and right sides of the flipping seat 3, one ends of the two linkage cylinders 73 are respectively hinged to the corresponding first fixing seats 71, and the other ends of the two linkage cylinders 73 are respectively hinged to the corresponding second fixing seats 72. The two linkage cylinders 73 are linked with each other and work synchronously. The flipping seat 3 is of an L-shaped structure. The number of the guide rails 31 is two, and the number of the sliders 8 is four. The first clamping plate 51 is slidably installed on the guide rails 31 through the two sliders 8, and the second clamping plate 52 is slidably installed on the guide rails 31 through the two sliders 8. During operation, the two linkage cylinders 73 drive their output ends to retract, the support assembly 2 supports the bottom of the flipping seat 3, and the first clamping plate 51 is installed on the flipping seat 3 through the two sliders 8. At this time, the first clamping plate 51 is in a horizontal state. Then, the first clamping plate 51 is abutted against the top surface of the placing table 4, and iron cores are stacked on the first clamping plate 51. After the iron cores are stacked, the second clamping plate 52 is installed on the flipping seat 3 through the two sliders 8. Then, the sliders 8 are slid along the length direction of the guide rails 31 until the second clamping plate 52 abuts against the stacked iron cores. At this time, the stacked iron cores are clamped between the first clamping plate 51 and the second clamping plate 52. Then, the first clamping plate 51 and the second clamping plate 52 are locked and fixed to the placing table 4 through the locking assembly 6, that is, the first clamping plate 51 and the second clamping plate 52 cannot move. Then, the two linkage cylinders 73 synchronously link and extend their respective output rods, so as to push up the flipping seat 3 and make the flipping seat 3 swing and flip along the supporting part at the rear end of the support assembly 2, specifically swing and flip by 90°, so that the iron cores are in a vertical state. Then, the locking assembly 6 is loosened, and the stacked iron cores are taken away by a forklift or a crane. After the iron cores are taken away, the two linkage cylinders 73 drive the flipping seat 3 to reset. In this application, through the first fixing seats 71, the second fixing seats 72 and the linkage cylinders 73, pneumatic linkage is adopted instead of hydraulic linkage, so as to avoid oil leakage or seepage of the linkage rods of the driving device 7 after long-term use, resulting in a decrease in the internal oil level and lifting failure, making the iron core flipping device more convenient, fast, safe and clean. Further, through the guide rails 31 and the sliders 8, the first clamping plate 51 and the second clamping plate 52 can move along the length direction of the guide rails 31 to adjust the clamping thickness between the two, which is applicable to the clamping of iron cores with different stacking thicknesses, achieving the effect of improving the versatility of the iron core flipping device.

[0032] Such as Figures 1-3As shown, the support assembly 2 includes support columns 21 and support plates 22; the number of the support columns 21 and the support plates 22 is two respectively.

When the flip seat 3 swings and flips, because the flip seat 3 is placed with stacked iron cores and has a heavy weight, the flip seat 3 will swing along the support of the support plate 22, specifically along the rounded corner 221 of the support plate 22, until the flip seat 3 fits against the rear side of the support plate 22. The rounded corner structure 221 is beneficial to improving the smoothness of the flipping and swinging of the flip seat 3.

[0033] As Figures 2-3 shown, a buffer pad 211 is provided on the top surface of the support column 21. In this embodiment, a buffer pad 211 made of rubber material is provided on the top surface of the support column 21. When the flip seat 3 is reset, the buffer pad 221 can play a role in buffering and shock absorption, so that the flip seat 3 can be stably reset and stopped, avoiding the phenomenon of damage caused by rigid collision.

[0034] As Figures 2-3 shown, a buffer strip 222 is provided on the rear side of the support plate 22. In this embodiment, a buffer strip 222 made of rubber material is provided on the rear side of the support plate 22.

Both ends of the locking frame strip 61 are movably installed in the through opening 412. The locking frame strip 61 is provided with a plurality of second locking holes 611 which are evenly spaced along the height direction of the locking frame strip 61. The second locking holes 611 can face the first locking holes 411. One end of the bolt 62 is installed in the first locking hole 411, and the other end of the bolt 62 is installed in the second locking hole 611. In this embodiment, after the first clamping plate 51 and the second clamping plate 52 clamp the iron core, both ends of the locking frame strip 61 are respectively installed in the through openings 412 of the two bumpers 41 and moved along the length direction of the through opening 412 until the locking frame strip 61 fits against the top surface of the second clamping plate 52. At this time, the first locking hole 411 faces the corresponding second locking hole 611. Then, one end of the bolt 62 is inserted into the first locking hole 411 and placed in the second locking hole 611. At this time, the first clamping plate 51 and the second clamping plate 52 are locked and fixed to the placing table 4 through the locking frame strip 61. Further, a clearance opening 32 corresponding to the through opening 412 is provided in the turning base 3, so as to facilitate the up and down movement adjustment of the locking frame strip 61 and be applicable to locking and fixing iron cores with different stacking thicknesses.

[0036] As Figure 4 shown, the turning base 3 is provided with a positioning table 33 which is located between the two guide rails 31, and the front side surface of the positioning table 33 protrudes from the front side surface of the guide rails 31. In this embodiment, the positioning table 33 is provided between the turning bases 3. The positioning table 33 is located in front of the two guide rails 31, and the front side surface of the positioning table 33 protrudes from the front side surface of the guide rails 31. When stacking the iron cores, the end of the patch can be abutted against the positioning table 33 as a positioning position to facilitate subsequent stacking. When the turning base 3 swings and turns, the positioning table 33 plays a supporting role to support the stacked and fixed iron core, avoiding the weight of the iron core acting on the two guide rails 31, thereby preventing the guide rails 31 from being deformed by pressure.

[0037] As Figures 4-5As shown, it further includes a connecting screw 91 and a connecting nut 92; the rear end faces of the first clamping plate 51 and the second clamping plate 52 are respectively fixedly installed with the connecting nut 92, and the slider 8 is connected to the connecting nut 92 through the connecting screw 91.
