The press-fitting part 2 is fixedly connected to the dividing disc 4, and the dividing disc 4 is also arranged on the workbench 3. When the index plate 4 rotates in place, the press-fitting portion 2 is stopped just inside the holder portion 1 so as to complete the press-fitting process.
Referring to fig. 2 and 3, the bracket part 1 includes a main bracket 11 and a hydraulic cylinder part 12. The main frame 11 is connected to the upper surface of the table 3 by a lower fixing plate 111, and the fixing plate 111 is provided with a hole. The top end of the main support is a top plate 112, and a downward limiting pressure head 5 is arranged on the lower surface of the top plate 112. The hydraulic cylinder part 12 is connected to the lower part of the table 3, and the ram 121 of the hydraulic cylinder part 12 passes through the perforations in the table 3 and the fixing plate 111. The center line of the ejector rod 121 is on the same straight line with the center line of the perforation and the limiting pressure head 5.
As shown in fig. 3, a clamping groove 1211 is formed at the top of the jack 121. The centerline of the slot 1211 should also be collinear with the centerline of the limit ram 5. The bolt is longer than the press-fit die, and the locking groove 1211 plays a role of clearance for the bolt to pass through.
As shown in connection with fig. 2, 4, 5 and 6. The press-fitting portion 2 includes a first press-fitting die 21 and a second press-fitting die 22. The first press-fitting die 21 and the second press-fitting die 22 are connected in a chute and slider mode. The first press-fitting die 21 is slidable up and down with respect to the second press-fitting die 22.
As shown in fig. 4 and 5, a protruding connecting portion 211 is provided on one side of the first press-fitting die 21, a bolt hole is provided on the connecting portion 211, the connecting portion 211 is connected with the index plate 4, and the entire press-fitting portion 2 is connected to the index plate 4.
