As shown in fig. 7, the high-speed profile measuring instrument 3 is mainly composed of a stand 3a, and a first measuring instrument 3b and a second measuring instrument 3c mounted on the stand 3a one above the other. For the iron cores of different specifications, the positions detected by the high-speed profile measuring instrument 3 are different, and the stepping module 3d is used for assisting automatic alignment of the measuring instrument, specifically: the vertical frame 3a is driven to move back and forth through the stepping module 3d, or the vertical frame 3a is driven to move left and right through the stepping module 3d, and the specific moving direction is determined according to the detected iron core. The first gauge 3b and the second gauge 3c are each provided with a horizontal rotary cylinder 3e.

The horizontal rotary cylinder 3e drives the high-speed profile measuring instrument to rotate 90 degrees to reach the detection position to detect the stacking height, and after detection, the horizontal rotary cylinder 3e drives the high-speed profile measuring instrument to retract, so that the lamination manipulator 1 retracts.
c. Each time the stack is completed, the measurement is preferably performed by the second measuring instrument 3c with lower level, for example, the detection range is 290mm; when the whole thickness of the iron core exceeds 290mm, the second measuring instrument 3c rotates by 90 degrees to retract, the higher first measuring instrument 3b detects the thickness, and the whole machine detection thickness can reach 560mm. For cores with a thickness exceeding 560mm, three gauges may also be used to measure together.

The scale plate 1e is provided with waist-shaped holes corresponding to the tool frames 1b, the two rows of tool frames 1b and the scale plate 1e are fixed together through bolts penetrating through the waist-shaped holes, and the bolts are provided with locking handles 1f to facilitate operation.
The lamination tool adopts the vacuum chuck 1c to absorb the silicon steel sheets, and the steel sheet pressing mechanism 1d is specially added in order to ensure that the silicon steel sheets are not taken away by the vacuum chuck 1c after lamination. Before the vacuum chuck 1c on the lamination tool sucks the silicon steel sheets and lamination is carried out, the steel sheet pressing mechanism 1d is in a retracted state. After lamination is finished, the steel sheet compressing mechanism 1d compresses the silicon steel sheet, and when the vacuum chuck 1c is completely separated from the silicon steel sheet, the steel sheet compressing mechanism 1d is retracted again, so that the vacuum chuck 1c is prevented from dragging or taking away after pressure relief. In order to enable the lamination tool to adapt to silicon steel sheets with various specifications and sizes, the scale plate 1e of the lamination tool is designed to be in a scale adjustable form, and the lateral limiting block 1g is provided with a scale pointer, so that the width of the two rows of tool frames 1b can be conveniently adjusted manually.

The X-direction screw centering mechanism 2b adopts a screw rod nut mechanism to adjust and center, the X-direction screw centering mechanism 2b improves the reliability of the positioning mechanism, and the transverse positioning center of the iron core lower clamp on the sliding table 4 is convenient to manually adjust; one end of the iron core Y, which is close to the iron core, is used as a reference, the other end of the iron core Y adopts a Y-direction positioning mechanism 2c, and the Y-direction positioning mechanism 2c adopts a manual adjustment mode, so that the iron cores with different longitudinal length specifications can be compatible, and the center position of the iron core Y is automatically aligned by a robot system through calculation.

As shown in fig. 5, two floating pins 8 are respectively arranged on the automatic lamination area 4a, the iron core upper clamp and base mounting area 4b, the iron core lower clamp mounting and finished product taking area 4c, and respectively correspond to a group of floating pin butt joint holes 2d of the lamination table 2. When the lamination stage 2 slides to this area, the two floating pins 8 of this area rise and are inserted into the floating pin docking holes 2d to achieve docking with the lamination stage 2. After the lamination of the iron core is finished, a floating pin on a transmission mechanism of the sliding table 4 is lifted to butt-joint the lamination table, and then the iron core is conveyed to each station.

At this time, the lamination area in the lamination workstation is empty, and manual clamping is a better process. Therefore, after the iron core is sent out, the other lamination table 2 installs the iron core lower clamp carrying the next iron core from the iron core lower clamp of the sliding table 4, the finished product taking area 4c enters the automatic lamination area 4a, and the lamination manipulator 1 continues to perform lamination work.
