[0001] This invention relates to the field of camshaft assembly equipment technology, specifically to a fully automated assembly equipment for engine camshaft covers. Background Technology

[0002] The engine camshaft is a core component of a piston engine, used to control the opening and closing of valves, ensuring sufficient intake and exhaust of air into the cylinders, and directly affecting the engine's power performance and operating characteristics. During engine camshaft assembly, a large camshaft cap and a small camshaft cap need to be installed on the cylinder head. Currently, these caps are typically assembled manually. The process involves first pressing the two ends of the large camshaft cap together using pin sleeves, then placing the large and small camshaft caps in their corresponding positions on the cylinder head, and finally installing the large and small bolts in their respective positions. This process is cumbersome, inefficient, and labor-intensive. Furthermore, manual assembly is prone to errors such as improper installation of the large and small camshaft caps and the falling of impurities. Therefore, a fully automated assembly machine for engine camshaft caps is needed. Summary of the Invention

The clamping cylinder 79 pushes the clamping block 78 forward, so that the clamping block 78 is inserted into the groove to fix the lifting guide rod 77 and prevent the cylinder head from falling during the pressing process. Specifically, after the cylinder head is moved to the corresponding position by the conveyor 1, the lifting assembly lifts the cylinder head, the cylinder head passes through the pressing hole 86 corresponding to the shelf 82, and then the pressing assembly performs the pressing action.

[0021] The pressing assembly includes a servo press 731 mounted on the top plate 73 and a pressure plate 732 disposed at the lower end of the servo press 731. Pressure heads 733 and clamping members 734 are distributed on both sides of the pressure plate 732 to press and install the pin sleeve via the pressure heads 733. The clamping member 734 includes a clamping claw cylinder and clamping plates disposed on the clamping arms on both sides of the clamping claw cylinder.

The platform 81 moves away, and the large shaft cover is pressed into the corresponding position of the cylinder cover by the push of the servo press 731.

[0023] like Figure 1 and Figure 7As shown, in this embodiment, the large bolt feeder 4 and the small bolt feeder 5 are respectively located at both ends of one side of the conveyor 1. A bolt feeding gripper is installed at the end of the second collaborative robot 12. The second collaborative robot 12 works in conjunction with the large bolt feeder 4 and the small bolt feeder 5 through the bolt feeding gripper to place the large and small bolts at corresponding positions on the cylinder head and the positioning platform 9. Specifically, the large bolt feeder 4 and the small bolt feeder 5 serve as bolt guiding devices, which are conventional technical equipment. The second collaborative robot 12, in conjunction with the bolt feeding gripper, is also a conventional technical means for picking up and placing bolts. Therefore, this embodiment will not further elaborate on the large bolt feeder 4, the small bolt feeder 5, and the bolt feeding gripper.

[0024] like Figure 7 , Figure 8 and Figure 9 As shown, in this embodiment, the small shaft cover feeder 6 is also equipped with a vision inspection camera 61. The small shaft cover feeder 6 is used to sequentially guide the trays, in which small shaft covers are placed.

The end of the third collaborative robot 13 is equipped with a second gripping component to grip the small shaft covers.

[0025] The second gripping component includes a second gripping plate 62 installed at the end of the third collaborative robot 13 and a lifting cylinder 63 vertically distributed at the lower end of the second gripping plate 62. The lower end of the output rod of the lifting cylinder 63 is fixedly provided with a cylinder plate 64. A third gripper cylinder 65 is vertically installed at the lower end of the cylinder plate 64. A third clamping plate 66 is installed on the two clamping arms of the third clamping cylinder 65 respectively. The lower ends of the third clamping plates 66 are provided with clamping rods on both sides, so as to insert the clamping rods into the corresponding holes of the small shaft cover, thereby clamping and fixing the small shaft cover.

[0026] The positioning platform 9 is provided with a first positioning plate 91 for placing the small shaft cover. The first positioning plate 91 is provided with a positioning groove 94, and the lower end of the positioning groove 94 is provided with an arc-shaped protrusion to support the small shaft cover. The upper end of the first positioning plate 91 is provided with a groove plate 95, and the groove plate 95 is provided with a corresponding groove corresponding to the positioning groove 94. A positioning cylinder 96 is provided on one side of the first positioning plate 91 to push the groove plate 95 to move.

[0028] Specifically, the working principle of this invention is as follows: Conveyor 1 guides the cylinder head forward, and each conveyor 1 is equipped with a blocking component to limit the cylinder head, so as to facilitate the assembly of the cylinder head. The first collaborative robot 11 grabs the pin sleeve from the pin sleeve feeder 3 and places the pin sleeve on the moved positioning mold seat 87. The positioning mold seat 87 moves to the lower end of the pressure plate 732 and lifts the pin sleeve by the lifting cylinder 88 and pushes the pressure head 733 up. Conveyor 1 moves the cylinder head to the lower end of the pin sleeve press 7. The lifting cylinder 76 is activated and the cylinder head is lifted and fixed by the lifting positioning rod 75. The clamping cylinder 79 pushes the clamping block 78 to clamp the lower end of the lifting guide rod 77, thereby preventing the cylinder head from falling. The servo press 731 controls the pressure head 733 to fall so as to install the pin sleeve in the corresponding position of the cylinder head. The first collaborative robot 11 grasps the large shaft cover, places it on the positioning mold base 87, and the positioning mold base 87 moves to the lower end of the pressure plate 732.

The third collaborative robot 13 uses the second gripping component to pick up the small shaft cover. The third collaborative robot 13 first picks up 4 small shaft covers and puts them on the first positioning plate 91, then picks up 5 small shaft covers and puts them into the cylinder cover. The third collaborative robot 13 returns to pick up 4 small shaft covers on the first positioning plate 91 and puts them into the cylinder cover again, completing the assembly of 9 small shaft covers.

[0030] The second collaborative robot 12 first places some large and small bolts on the positioning table 9 through the bolt feeding gripper, and then picks them up and puts them into the shaft cover. In this way, 18 small bolts (small shaft cover bolts) + 3 large bolts (large shaft cover bolts) are picked up and put into the corresponding shaft cover in sequence. The fourth collaborative robot 14 tightens the bolts through the tightening assembly, realizing the automated assembly of the large shaft cover and the small shaft cover.
