[0003] Before installing the piston connecting rod assembly, a connecting rod sleeve needs to be installed at the installation position as a guide sleeve. However, the existing connecting rod sleeves are all manually aligned and assembled. During assembly, due to manual installation, it is not easy to align the position, or due to tilting, it is easy to get stuck on the wall at the installation position, which can easily cause damage or wear, affecting the installation accuracy. Moreover, manual assembly requires alignment, and the assembly time for a single piece can be as long as 15-20 minutes. Furthermore, the pass rate is greatly affected by human factors and fluctuates greatly, making it difficult to meet the needs of large-scale production. Utility model content:

[0043] The printing plate forward and backward moving mechanism 30 includes a linear module 32 extending forward and backward, which is fixed to the top surface of the top plate of the frame 10. The receiving plate 31 is fixed to the top surface of the moving block on the linear module 32. The top surfaces of the top plates of the frame 10 on the left and right sides of the linear module 32 are fixed with forward and backward extending guide rails 34. The left and right sides of the bottom surface of the receiving plate 31 are fixed with guide sliders, which are inserted into the guide grooves of the corresponding guide rails 34 and cooperate with them.

[0044] A limit sensor block 35 is fixed on the left side wall of the receiving plate 31. Support plates are fixed on the front and middle parts of the left side of the receiving plate 31.

[0045] The lower part of the frame 10 is fixed with a control host, and an operation panel is fixed on the outside of it. All electrical components used in this embodiment are electrically connected to the control host through electrical connection lines. All cylinders in this embodiment are connected to the pneumatic system through connecting pipes. The pneumatic system controls the corresponding control valve to realize the action of the corresponding cylinder. It is also controlled by the control host. They are all conventional structures and will not be described in detail here.

[0046] In this embodiment, first loosen the locking nut, open the engine mounting plate 50, and let the engine 100 enter the upper protective cover 1 along the inlet / outlet channel 2 and place it on the top surface of the engine mounting plate 50. Press the right side wall and rear side wall of the engine 100 against the corresponding anti-slip layer 53 (the position of the anti-slip layer 53 can be changed by loosening the corresponding locking nut and rotating the adjusting bolt 51 to ensure that the engine 100 is accurately positioned). Then, push the push rods of all the pressing cylinders 55 to make the pressing plate 56 press against the corresponding wall surface of the engine 100 to fix it. The proximity switch 7 will detect that the engine 100 is installed in place.

[0047] Then, the door panel 3 is closed, and protective gas (such as nitrogen or other inert gas) is introduced into the upper protective cover 1 to expel the air inside the upper protective cover 1. Then, the top surface of the engine 100 is photographed by the industrial camera 8 and its matching engine 100 is checked. If the check is correct, the 3D printing device 20 prints two matching connecting rod sleeves on the receiving plate 31. At this time, the receiving plate 31 is in the rear, and its limit sensing block 35 is sensed by the third proximity switch 36 in the middle. After printing is completed, the protective gas can be stopped. The receiving plate 31 is moved to the front by the linear module 32, so that the third proximity switch 36 in the front senses the corresponding limit sensing block 35, indicating that it has moved into place. Then, the rotating shaft of the rotary cylinder 12 is rotated so that the sensing end of the second proximity switch 111 on the right senses the sensing part, indicating that it has rotated into place. Then, the moving block is moved forward by the rear moving motor and is sensed by the fifth proximity switch in the front, indicating that it has moved into place. The rear moving motor stops running.

[0048] At this time, the two receiving plates 31 are above the corresponding connecting rod sleeves. Then, the lifting servo motor 132 operates, causing the horizontal plate 41 to descend. During descent, proximity switches are fixed on the opposite walls of the top and bottom plates of the lifting adjustment mechanism 13. When the bottom end of the lifting block 131 approaches the proximity switch, it indicates that it has moved into position. Then, the gripping cylinder 42 operates, causing the vacuum suction cup 44 to press against the corresponding connecting rod sleeve, adsorbing it. The corresponding proximity switch senses the connecting rod sleeve, indicating that it has been gripped in place. Then, the push rod of the gripping cylinder 42 retracts, and the lifting block 131 rises. It is sensed by the proximity switch above, indicating that it has moved into position. Then, the rotary cylinder 12 operates, moving the connecting rod sleeve to the engine 1. Directly above the engine 100, since both the lifting servo motor 132 and the rear movement motor are servo motors, they can accurately move the gripping plate 43 forward and backward and up and down, precisely moving it to directly above the position to be installed on the engine 100. Then, the lifting block 131 descends to a set distance (the distance from the top of the lifting block 131 to the engine 100 can be precisely determined by the number of rotations of the shaft of the lifting servo motor 132). After descending, the push rod of the gripping cylinder 42 pushes the connecting rod sleeve into the corresponding position on the engine 100. After completion, all parts return to their original positions, the door panel 3 is opened, and the engine 100 can be taken out for subsequent parts installation. It is very convenient, with good installation effect and high installation accuracy.

[0049] Finally, the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model, and the patent protection scope of the present utility model should be defined by the claims.
