A feeding seat 2 and a cylinder seat 3 are respectively arranged on both sides of the base plate 1. The feeding seat 2 has a positioning groove 201, on which a floating positioning seat 4 is provided. The positioning groove 201 is used to install the floating positioning seat 4. A pressing cylinder 5 is fixedly connected to the cylinder seat 3. A lifting plate 6 is fixedly connected to the piston rod of the pressing cylinder 5. Pressing arms 601 are provided at both ends of the lifting plate 6. Hinge seats 7 are provided on both sides of the feeding seat 2 on the base plate 1. A swing arm 8 is hinged to the hinge seat 7. A torsion spring is provided at the connection between the swing arm 8 and the hinge seat 7. A clearance groove 801 is opened at the end of the swing arm 8 near the loading seat 2. The two ends of the loading seat 2 are slidably connected to the clearance grooves 801 of the two swing arms 8 respectively. A roller 802 is rotatably connected at the end of the swing arm 8 near the pressure arm 601. The roller 802 is tangent to the lower end of the swing arm 8. A bracket 602 is provided in the middle of the lifting plate 6. A pressure head 603 is detachably connected to the lower part of the bracket 602. The pressure head 603 can be lowered to press.

[0020] The positioning groove 201 is provided with a first spring 202 and a locking block 203. The floating positioning seat 4 is provided with a positioning block. The positioning block is provided with a groove corresponding to the locking block 203. The positioning block is used to lock the floating positioning seat 4 in conjunction with the locking block 203. The locking block 203 is slidably connected to the positioning groove 201. The positioning groove 201 can guide the sliding of the locking block 203.

[0021] A guide rail 9 is fixedly connected to the seat plate 1. The feeding seat 2 is slidably connected to the guide rail 9. The guide rail 9 can guide and limit the sliding stroke of the feeding seat 2. The feeding seat 2 has guide posts at both ends. The guide posts are slidably connected to the relief groove 801. The swing arm 8 can drive the feeding seat 2 to slide during the swinging process.

[0022] The swing arm 8 is V-shaped, and the middle part of the swing arm 8 is hinged to the hinge seat 7.

[0023] The pressure arm 601 is L-shaped. The horizontal section of the pressure arm 601 is tangent to the roller 802. The lifting and lowering action of the pressure arm 601 can drive the swing arm 8 to swing around the hinge seat 7.

The positioning plate can be lowered relative to the base during the pressing process. The second spring is located between the positioning plate and the base and is used to reset the positioning plate. The positioning block is located at the bottom of the base.

[0026] The working principle of this utility model is as follows: The shaft seat with the pre-installed round shaft is placed on the positioning plate of the floating positioning seat 4 (the positioning plate is provided with corresponding positioning holes). Then, the piston rod of the pressing cylinder 5 extends, the lifting plate 6 moves down, and under the action of the pressing arm 601, the swing arm 8 rotates clockwise. On the one hand, the loading seat pressing head 603 descends vertically, and on the other hand, the loading seat 2 slides down the pressing head. During this process, the pressing head 603 first contacts the round shaft and presses down, and the positioning plate moves down relative to the base until the pressing head 603 presses the round shaft completely into the shaft seat. At this time, the assembly is completed, and then the pressing cylinder 5 is reset.
