Detailed implementation manners

[0026] In combination with the attached drawings and specific embodiments, the present utility model will be further described. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the present utility model, those skilled in the art can make various changes or modifications to the present utility model, and these equivalent forms also fall within the scope defined by this application.

[0027] Refer to Figure 1 shown, which is a schematic diagram of the cylinder block and bearing cap structure. In the illustration, a total of 5 bearing caps 1 are installed on the cylinder block 2. The bearing caps 1 are installed on the cylinder block 2 at intervals in sequence and are fixed by bolts 3. The cylinder block, bearing cap and bolt mechanism provided in this embodiment mainly places the bolts 3 into the corresponding installation holes of the bearing caps 1, and then sends them to the next automatic tightening process to tighten the bolts 3.

[0028] Refer toFigure 2 As shown, it is a schematic diagram of the overall structure of the cylinder block and valve cover bolt installation mechanism provided in this embodiment. It mainly includes a bolt installation workbench 4. At the bolt installation workbench 4, there is a bolt installation cylinder block lifting assembly 6. After the valve cover 1 is placed on the cylinder block 2, it is transported to the position of the bolt installation workbench 4 through a conveyor line, and then lifted and positioned by the bolt installation cylinder block lifting assembly 6, so as to facilitate the installation of the bolt 3. A bolt vibrating disk 5 is arranged on one side of the bolt installation cylinder block lifting assembly 6. The bolt vibrating disk 5 is mainly used to provide the bolts 3 used for installation. The outlet of the bolt vibrating disk 5 is a linear vibration, and the bolts 3 are sequentially transported to the outlet position through vibration. A bolt sorting assembly 7 is arranged at its outlet position. The bolt sorting assembly 7 mainly sorts the bolts so that they are in groups of two, and arranges and positions the two bolts 3 at the same spacing as the installation holes of the valve cover 1 to facilitate the grasping of the subsequent bolt installation assembly 8. The bolt installation assembly 8 is arranged above the bolt sorting assembly 7, and it can achieve multi-degree-of-freedom movement. It first moves to the position of the bolt sorting assembly 7 to grasp the bolt 3, and then moves to the corresponding position above the valve cover 1 to put the bolt 3 into the installation hole of the valve cover 1. After all the bolts 3 are installed, the cylinder block 2 can move to the next process to automatically tighten the bolts 3.

[0029] Refer to Figure 3 As shown, the bolt installation cylinder block lifting assembly 6 mainly includes a bolt installation cylinder block positioning plate 10. A bolt installation cylinder block lifting cylinder 9 is connected below the bolt installation cylinder block positioning plate 10. A bolt installation roller way blocking block 12 is arranged on one side of the bolt installation cylinder block positioning plate 10, and the bolt installation roller way blocking block 12 is connected to a bolt installation roller way blocking cylinder 11. When the cylinder block transported from the previous process reaches the position of the bolt installation workbench 4, the front end is blocked and limited by the rising bolt installation roller way blocking block 12, and the rear end is limited by a backstop block. Then the bolt installation cylinder block lifting cylinder 9 is started to raise the bolt installation cylinder block positioning plate 10 to separate the cylinder block from the conveying track, and then the bolt 3 is installed.

[0030] Refer to Figure 4 And Figure 5As shown, the bolt sorting assembly 7 mainly includes a material receiving block 13, a material dividing plate 16, and a material pushing block 15. Among them, the material receiving block 13 has a material receiving block inlet channel 19 and a material receiving block outlet channel 20 that are perpendicular to each other. The material receiving block inlet channel 19 corresponds to the outlet of the bolt vibrating disk 5, and the bolts 3 sequentially enter the material receiving block inlet channel 19. The material pushing block 15 is arranged in the material receiving block outlet channel 20, and the material pushing block 15 is connected to a material pushing block cylinder 14. When the bolts enter the connection position of the material receiving block inlet channel 19 and the material receiving block outlet channel 20, the material pushing block cylinder 14 acts, causing the material pushing block 15 to convey the bolts 3 backward. A material dividing plate 16 is arranged at the end of the material receiving block outlet channel 20. Two bolt positioning grooves 21 with a certain spacing are arranged on the material dividing plate 16, and the material dividing plate 16 is connected to a material dividing plate cylinder 22. The material dividing plate cylinder 22 controls the movement of the material dividing plate 16. First, one of the bolt positioning grooves 21 is aligned with the material receiving block outlet channel 20. Under the action of the material pushing block 15, a bolt enters the bolt positioning groove 21. Then the material dividing plate cylinder 22 acts again, causing the other bolt positioning groove 21 to be aligned with the material receiving block outlet channel 20. Under the action of the material pushing block 15, a bolt enters the other bolt positioning groove 21, thus realizing the arrangement of two bolts 3. Two lifting heads 18 are located below the two bolts 3 and lift the two bolts 3 under the action of the bolt lifting cylinder 17. At this time, the two bolts 3 are in the Figure 4 state shown, waiting to be grabbed by the bolt installation assembly 8.

[0031] Refer to Figure 6 and Figure 7 As shown, the bolt installation assembly 8 of this embodiment includes a bolt installation front-back movement assembly 23, a bolt installation left-right movement assembly 24, a bolt installation up-down movement assembly 25, and a fixture plate 26. The multi-directional movement of the fixture plate 26 is driven by the bolt installation front-back movement assembly 23, the bolt installation left-right movement assembly 24, and the bolt installation up-down movement assembly 25, so as to grab the bolts and shift them to be installed on the tile cover.

[0032] A bolt clamping cylinder 27 is installed on the fixture plate 26. The bolt clamping cylinder 27 is connected to a bolt clamping head 28. The action of the bolt clamping head 28 is controlled by the bolt clamping cylinder 27 to clamp the bolts 3, and the bolts 3 are installed into the installation holes of the tile cover through the bolt installation up-down movement assembly 25.

[0033] In this embodiment, four bolt clamping cylinders 27 are provided, and each bolt clamping cylinder 27 is connected to a bolt clamping head 28. In the structural design of this embodiment, the equipment can realize the installation of two different types of valve cover bolts. The difference between the two different types of valve covers lies in the different bolt installation spacings. Therefore, among the four bolt clamping heads 28, the two bolt clamping heads 28 on one side and the two bolt clamping heads 28 on the other side can be designed with different spacings to adapt to the installation of valve covers with different hole pitches. The spacing between the two bolt clamping heads 28 on each side is the same as the bolt positioning groove 21 in the corresponding bolt sorting assembly 7. That is, when installing bolts, for one type of valve cover, the corresponding bolt sorting assembly 7 and bolt clamping head 28 are used, and for the other type of valve cover, the corresponding other bolt sorting assembly 7 and bolt clamping head 28 are used, so as to meet the installation requirements of the two valve covers.
