[0042] The push rod 61, one end of which is connected to the floating plate 5 and is used to connect a driving member to push the floating plate 5 away from the bottom plate 1; the push rod 61 is pushed upward by the telescopic movement of the air cylinder.

[0043] The elastic element 62 is sleeved on the push rod 61, and its two ends respectively elastically abut against the upper flat plate 2 and the floating plate 5 for pushing the floating plate 5 close to the bottom plate 1. The elastic element 62 can be a compression spring. After the push rod 61 pushes the floating plate 5 upward, the first clamping jaw 7 and the second clamping jaw 8 will move upward and move to both sides, thus opening, and then the core 3 is placed in. The air cylinder contracts, and the compression spring makes the floating plate 5 move downward through its own elastic potential energy, driving the first clamping jaw 7 and the second clamping jaw 8 to approach each other, and at the same time, pressing and installing the core 3.

[0044] As Figures 1 to 6 shown, the first clamping jaw 7 and the second clamping jaw 8 are respectively connected to the clamping jaw mounting plate 91 through the clamping jaw connecting arms 9, the clamping jaw mounting plate 91 is connected to the slide rail mounting seat 93 through the limit block 92, the limit block 92 is provided with a slide block 921, and the slide block 921 is located on the slide rail mounting seat 93 for preventing the limit block 92 from falling off the slide rail mounting seat 93.

[0046] As Figure 1 shown, the first clamping jaw 7 and the second clamping jaw 8 are respectively provided with a first anti-scratch pad 71 and a second anti-scratch pad 81. To prevent scratches during the press-fitting of the core 3.

[0047] As Figure 4 shown, one side of each end of the slide rail mounting seat 93 is connected with a stop block 932 through a locking nut 931, and an adjusting bolt 933 is provided on the stop block 932. The horizontal movement distance of the limit bar 922 is limited by the adjusting bolt 933, and the stop block 932 is located on one side of the limit bar 922.

[0049] As Figures 3 to 6As shown, on one side of each of the two limiting blocks 92, there are limiting strips 922 with an L-shaped structure. The limiting strips 922 are used to limit the sliding distance of the jaw mounting plate 91 on the slide rail mounting seat 93. On the other side, there are a first slide plate 923 and a second slide plate 924 respectively. A first cam 925 is connected to the first slide plate 923.

[0051] As Figure 4 shown, the floating plate 5 is connected to the slide rail mounting seat 93 through a right-angle connecting block 51.

[0052] As Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 shown, rectangular through holes 11 are formed in the middle of both sides of the long side of the bottom plate 1. A buffer seat 12 is provided on the bottom plate 1. An oil buffer 13 is provided on the buffer seat 12. It is used to buffer the downward moving slide rail mounting seat 93.

[0053] Working process: By means of the reciprocating telescoping of the cylinder and the self-resetting of the compression spring, the first jaw and the second jaw are driven to perform the opening and closing actions, so as to realize the pressing and releasing of the core 3. When the transfer fixture moves to a fixed position, the cylinder at this position extends, pushes the push rod 61, drives the floating plate 5 to move upward. The floating plate 5 will drive the entire slide rail mounting seat 93 to move upward and separate from the top of the oil buffer 13. At the same time, the elastic element 62 is in a compressed state. During the upward movement of the slide rail mounting seat 93, the first cam 925 and the second cam 926 on the first slide plate 923 and the second slide plate 924 will move in the first chute 41 and the second chute 42 on the limiting plate 4, and cause the slider 921 on the slide rail mounting seat 93 to move to both sides inside it, thereby driving the jaw mounting plate 91 to move. The jaw mounting plate 91 drives the first jaw 7 and the second jaw 8 to move to both sides simultaneously through the jaw connecting arm 9, so as to realize the upward movement of the first jaw 7 and the second jaw 8 while moving open to both sides, and place the core 3 on the contact plate 22.

[0054] After the core 3 is placed, the air cylinder retracts. Under the action of the self-resetting of the compression spring, the first pressing claw 7 and the second pressing claw 8 move back to their original closed state. Under the action of the elastic potential energy of the compression spring, the core 3 is press-fitted and fixed. At the same time, the oil buffer 13 on the buffer seat 12 will buffer the downward moving slide rail mounting seat 93.
