[0029] In the technical solution of this embodiment, a plurality of movable plates 4 are provided, each of which is provided with a placement groove 5. Each placement groove 5 can realize the placement operation of an engine cylinder head non-return valve, so that the device can realize the transfer of multiple engine cylinder head non-return valves at the same time, thereby improving the conveying efficiency of the press-fitting of the engine cylinder head non-return valve, and the rotation of the round shell 3 can be realized by the driving of the driving assembly 13, and the round shell 3 drives the movable plate 4 to rotate together. When the roller 6 on the movable plate 4 moves to the position of the fixed plate 7, the fixed plate 7 pushes the movable plate 4, and the position of the placement groove 5 on the movable plate 4 changes. At this time, the engine cylinder head non-return valve is conveyed to the placement groove 5 by the external conveying device on one side to realize the loading function, and the engine cylinder head non-return valve is moved to the installation position on the upper side of the engine cylinder head by the movable plate 4 on the other side, thereby realizing the alignment of the assembly and improving the press-fitting accuracy of the engine cylinder head non-return valve.

[0030] Among them, an annular groove 24 is opened on the outer wall of the fixed tube 2, and an annular plate 25 is fixedly connected to the inner wall of the circular shell 3. The annular plate 25 is movably connected to the annular groove 24, which can make the circular shell 3 rotate stably on the fixed tube 2, improve the conveying accuracy, and facilitate press-fitting production;

[0031] Furthermore, the fixed plate 7 is arranged in a fan shape, and the fixed plate 7 is arranged at the same height as the movable plate 4, so as to facilitate contact with the roller 6, thereby pushing the movable plate 4;

[0032] Furthermore, the placement groove 5 is set through the side wall of the movable plate 4 away from the circular shell 3, and the placement groove 5 is fixedly connected with an anti-slip pad 26, which improves the reliability of positioning the one-way valve of the engine cylinder head and facilitates press-fitting use;

[0033] A movable rod 8 is movably connected to the inner cavity of the fixed tube 2, and a mounting plate 9 is fixedly connected to the top of the movable rod 8. A counterweight 10 is installed on the bottom surface of the mounting plate 9.

[0034] In the technical solution of this embodiment, a counterweight 10 of a specified weight is installed on the mounting plate 9 according to the pressing force during the press-fitting operation of the engine cylinder head non-return valve, so as to realize the control of the pressing force and facilitate the improvement of the press-fitting accuracy of the engine cylinder head non-return valve. Then, under the drive of the driving assembly 13, the fixed rod 12 can be moved on the upper side of the push plate 19. When the movable plate 4 moves the engine cylinder head non-return valve to the specified position, the fixed rod 12 moves to a position on the side of the push plate 19. Under the action of gravity, the fixed rod 12 slides from the highest point of the push plate 19, and the fixed rod 12 drives the movable rod 8 to move, and the movable rod 8 drives the mounting plate 9 to move, so that the counterweight 10 on the mounting plate 9 performs the press-fitting operation on the engine cylinder head non-return valve. The operation is convenient and the press-fitting efficiency of the engine cylinder head non-return valve is effectively improved.

[0035] A drive assembly 13 is provided on the top surface of the base plate 1. The drive assembly 13 includes a motor 14, which is fixedly connected to the base plate 1. A drive shaft 15 is fixedly connected to the rotor of the motor 14. A first gear 16 is fixedly connected to the top of the drive shaft 15. A ring gear 17 is engaged with one side of the first gear 16. The ring gear 17 is fixedly connected to the circular shell 3. A circular plate 18 is fixedly connected to the side wall of the drive shaft 15. The fixing rod 12 is provided on the top surface of the circular plate 18. A plurality of push plates 19 are evenly distributed and fixedly connected to the top surface of the circular plate 18.

[0036] In the technical solution of this embodiment, by starting the motor 14 and controlling the angle of a single rotation of the motor 14, the motor 14 drives the drive shaft 15 to rotate, and the drive shaft 15 drives the first gear 16 and the circular plate 18 thereon to rotate. The first gear 16 is engaged and rotated with the ring gear 17, which can drive the circular shell 3 to rotate, so that the positioning and transfer operation of the one-way valve of the engine cylinder head can be achieved. The push plate 19 is driven to move by the circular plate 18, and the push plate 19 pushes the fixed rod 12, so that the counterweight block 10 can be continuously reciprocated up and down, and a constant force press-fitting operation is achieved, thereby improving the press-fitting accuracy of the one-way valve of the engine cylinder head and achieving a good use effect.

[0037] Furthermore, the push plate 19 is arranged in an arc shape, the top surface of the push plate 19 is arranged inclined, and the number of push plates 19 is set to be the same as the number of movable plates 4. The push plate 19 can be used to lift the fixed rod 12, which facilitates the press-fitting operation of the cylinder head one-way valve.

[0038] Working principle: When using this press-fitting device, first fix the press-fitting device to the specified position on the engine production line, and install a counterweight block 10 of a specified weight on the mounting plate 9 according to the pressing force during the press-fitting operation of the engine cylinder head non-return valve to realize the control of the pressing force. Then start the motor 14 and control the angle of the motor 14's single rotation. The motor 14 drives the drive shaft 15 to rotate, and the drive shaft 15 drives the first gear 16 and the circular plate 18 thereon to rotate. The first gear 16 is engaged and rotated with the ring gear 17, which can drive the circular shell 3 to rotate, and the circular shell 3 drives the movable plate 4 to rotate together. When the roller 6 on the movable plate 4 moves to the position of the fixed plate 7, the fixed plate 7 is used to press the movable plate 4. Pushing is performed, and the position of the placement slot 5 on the movable plate 4 changes. At this time, one side conveys the engine cylinder head one-way valve to the placement slot 5 through an external conveying device to realize the loading function, and the other side moves the engine cylinder head one-way valve to the upper installation position of the engine cylinder head through the movable plate 4 to realize assembly alignment. At the same time, the fixed rod 12 moves to a position on one side of the push plate 19, and the fixed rod 12 slides from the highest point of the push plate 19 under the action of gravity. The fixed rod 12 drives the movable rod 8 to move, and the movable rod 8 drives the mounting plate 9 to move, so that the counterweight block 10 on the mounting plate 9 performs a press-fit operation on the engine cylinder head one-way valve, realizing a constant-force press-fit operation, thereby improving the press-fitting accuracy of the engine cylinder head one-way valve and achieving good use effect.
