[0047] A mechanical hand for clamping an iron core and an iron core mold laminating system having the same, as shown in Figures 1-15 includes a mechanical hand 1, a limiting device 3 and a conveying device 4.

[0048] A mechanical hand for clamping an iron core, as shown in Figures 1-6 includes a first clamping unit and a second clamping unit, the first clamping unit is used to support the iron core 5 to prevent the magnetic steel in the iron core 5 from falling off, the second clamping unit is used to clamp the iron core 5, and the first clamping unit is provided with at least two to ensure the support of the iron core 5.

[0049] The connecting rod fixing seat 11 is arranged on the mechanical arm 1, and is used to connect the mechanical arm 1 and the rotating mechanical arm 2, so that the mechanical arm 1 can be rotated or moved. The connecting block is arranged on the connecting rod fixing seat 11. The support plate 12 is arranged on the side of the connecting block away from the connecting rod fixing seat 11. The first clamping unit is connected with the support plate 12. The connecting block is arranged to leave a gap between the connecting rod fixing seat 11 and the support plate 12, so that the first clamping unit is conveniently arranged.

[0050] The first clamping unit comprises a first driving member 131, a connecting plate 132 and a supporting plate 133 which are sequentially connected. The first driving member 131 is arranged on the support plate 12. The first driving member 131 is arranged as a first driving cylinder. The moving end of the first driving cylinder faces outward. The connecting plate 132 is connected with the moving end of the first driving cylinder. When the moving end is extended or retracted, the connecting plate 132 moves in the direction of approaching or moving away from the iron core 5. The supporting plate 133 is connected with the connecting plate 132. The supporting plate 133 is arranged at the end of the connecting plate 132 away from the first driving cylinder. The arrangement direction of the supporting plate 133 is the same as the radial direction of the iron core 5. The supporting plate 133 extends to the center of the iron core 5, and is used to support the iron core 5 and prevent the magnetic steel in the iron core 5 from falling off. The first driving member 131 drives the connecting plate 132 to move in the direction of approaching or moving away from the iron core 5, and synchronously drives the supporting plate 133 to support or release the iron core 5.

[0051] The first clamping unit is arranged at least twice, so as to support the iron core 5 and prevent the magnetic steel from falling off. However, if only two first clamping units are arranged, the supporting plate 133 needs to be large enough to ensure that all the magnetic steels do not fall off. However, the connection of the connecting plate 132 to the supporting plate 133 is not necessarily reliable, which causes unstable support and leads to the magnetic steel falling off or even the iron core 5 falling off. Therefore, in the present scheme, the first clamping unit is arranged four times. The four first clamping units are uniformly arranged. The four first driving cylinders are uniformly arranged on the support plate 12. The four supporting plates 133 can cover the iron core 5, so as to prevent the magnetic steel from falling off.

[0052] The second clamping unit comprises a second driving member 141, a movable turntable 142, a following rod 143 and a clamping member 144 connected in sequence. First and second fixed plates 15 and 16 are arranged on both sides of the movable turntable 142. The movable turntable 142 can rotate between the first and second fixed plates 15 and 16. The first fixed plate 15 is in contact with the iron core 5. The second fixed plate 16 is provided with a connecting groove 161. The second driving member 141 passes through the connecting groove 161 and is connected with the movable turntable 142. The connecting groove 161 is arc-shaped, and the center of the arc-shaped connecting groove 161 coincides with the center of the movable turntable 142. A driving block 1422 is arranged on the movable turntable 142. The driving block 1422 is arranged in the connecting groove 161. The shape of the driving block 1422 is adapted to the connecting groove 161, but is smaller than the connecting groove 161, so that the driving block 1422 can move in the connecting groove 161. The driving block 1422 is connected with the second driving member 141. The second driving member 141 drives the driving block 1422 to move in the connecting groove 161, synchronously driving the movable turntable 142 to rotate. The center of the arc-shaped connecting groove 161 coincides with the center of the movable turntable 142, so that the movable turntable 142 can also rotate at the same angle when the driving block 1422 moves in the connecting groove 161.

[0053] The second driving member 141 is a second driving cylinder. The fixed end of the second driving cylinder is provided with a connecting arm 17. The connecting arm 17 is fixed on the second fixed plate 16. The second driving cylinder is fixed on the second fixed plate 16 through the connecting arm 17. The moving end of the second driving cylinder is connected with the driving block 1422. When the moving end of the second driving cylinder extends or retracts, the driving block 1422 moves in the connecting groove 161 away from or close to the fixed end of the second driving cylinder, pulling the movable turntable 142 to rotate.

[0054] The first inclined groove 1421 is formed in the movable turntable 142, the following rod 143 is arranged in the first inclined groove 1421, the following rod 143 is connected with the clamping piece 144, when the second driving cylinder drives the movable turntable 142 to rotate, the following rod 143 moves in the first inclined groove 1421, drives the clamping piece 144 to move to the direction close to or away from the iron core 5, clamps or releases the iron core 5. The clamping piece 144 comprises a clamping connecting plate 1441, a fixed plate 1442 and a clamping iron core plate 1443, the clamping connecting plate 1441 is connected with the following rod 143, the fixed plate 1442 is used for connecting the clamping connecting plate 1441 and the clamping iron core plate 1443, and the clamping iron core plate 1443 is used for clamping the iron core 5. Since the outer ring of the iron core 5 is circular, the side close to the iron core 5 of the clamping iron core plate 1443 is arranged in an arc shape, so that the iron core 5 can be clamped better. Of course, the clamping piece 144 can also be arranged in other structures, as long as the function of clamping the iron core 5 can be realized.

[0055] In order to ensure the clamping of the iron core 5, the clamping piece 144 is arranged at least two to form a mutual force to clamp the iron core 5, but in order to clamp the iron core 5 better, the clamping piece 144 is arranged three, and the three clamping pieces 144 are arranged uniformly.

The moving plate 313 is driven to move on the first sliding rail 311. The limiting part is arranged on the moving plate 313. The limiting part is synchronously driven to move towards or away from the lower mold 61, so as to clamp the inclined pole 611 of the lower mold 61.

The second sliding rail 321 is arranged in two parts. The two second sliding rails 321 are arranged at intervals. The two second sliding rails 321 extend towards the direction in which the lower mold 61 is placed. The second sliding block 322 is arranged on the second sliding rail 321. The second sliding block 322 moves on the second sliding rail 321. A guide rod 3221 is arranged on the second sliding block 322. The guide rod 3221 is connected with the clamping plate 324.

In order to ensure that the two clamping plates 324 move towards or away from each other when the driving plates 323 move simultaneously and in the same direction, the two second inclined slots 3241 arranged on the clamping plate 324 are symmetrically arranged along the connecting line of the two inclined poles 611. The guide rod 3221 is arranged in the second inclined slot 3241, and when the second sliding block 322 moves towards or away from the lower mold 61, the guide rod 3221 drives the clamping plate 324 to move towards or away from each other.
