[0034] The utility model is further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the utility model and are not used to limit the scope of the utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by this application.

[0035] refer to Figure 1 As shown in FIG. 1 , a schematic diagram of the cylinder body tile cover structure is shown. In the figure, a total of five tile covers 1 are installed on the cylinder body 2, and the tile covers 1 are installed on the cylinder body 2 in sequence. Figure 2 As shown, a pre-installation structure of a tile cover provided in this embodiment is required, and the pin sleeve needs to be pressed onto the tile cover 1 before the tile cover 1 is installed on the cylinder body 2. In another structure provided in this embodiment, the tile cover 1 does not need to be pressed onto the pin sleeve, but can be directly installed on the cylinder body 2. The tile cover installation line provided in this application can realize the automatic installation of the above two types of tile covers on the cylinder body.

[0036] refer to Figure 3 , Figure 4 The installation line of this embodiment includes a cylinder conveying track mechanism 3, at the end of which a cylinder positioning mechanism 4 is arranged, and the engine cylinder enters through the cylinder conveying track mechanism 3 and is then sent into the cylinder positioning mechanism 4, where the cylinder is positioned and waits for the installation of the tile cover.

[0037] Among them, a tile cover installation mechanism 5 is arranged above the cylinder positioning mechanism 4, and a rotating table mechanism 7 is arranged on one side of the cylinder positioning mechanism 4. The rotating table mechanism 7 is divided into four stations: a tile cover loading station, a pin sleeve pressing station, a tile cover unloading station, and a waiting station. The rotating table mechanism 7 realizes the switching of the above four stations by rotating 90° each time. At the tile cover loading station, the tile cover can be placed on the rotating table 71 by a configured manipulator or manually, and the rotating table 71 rotates. At the pin sleeve pressing station, two pin sleeves are pressed onto the tile cover 1 by the pin sleeve pressing mechanism 9, and then the tile cover 1 with the pin sleeves pressed is moved to the tile cover unloading station. At the tile cover unloading station, the tile cover is grabbed by the tile cover picking mechanism 6 and sent to the pin sleeve pressing mechanism 5, and the tile cover is pressed onto the cylinder body by the pin sleeve pressing mechanism 5. For the tile caps that do not need to be installed with pin sleeves, after the tile caps are loaded, the rotary table can directly rotate 180° to send the tile caps to the tile cap unloading station, and then be taken away by the tile cap taking mechanism 6.

[0038] refer to Figure 5 As shown, in this embodiment, the cylinder positioning mechanism 4 includes a cylinder block 45, a cylinder clamp 41 and a cylinder pressing member 43. The cylinder block 45 is located in the middle of the mechanism, and is controlled by a cylinder block lifting cylinder 46, which blocks the cylinder when it is lifted to facilitate its positioning. The cylinder clamp 41 is arranged on both sides of the mechanism, and the cylinder is clamped and fixed and centrally positioned from both sides through the connected cylinder clamping translation cylinder. A plurality of cylinder pressing members 43 are arranged on the upper part, and the cylinder is pressed downward by the connected cylinder pressing lifting cylinder 44 to ensure stability when the tile cover is pressed.

[0039] The relevant structures of the tile cover installation mechanism 5 and the tile cover material taking mechanism 6 are referenced Figure 6 , Figure 7 as well as Figure 8 The tile cover picking mechanism 6 is mainly used to grab the tile cover 1 located on the rotating table 71 on one side thereof, and mainly comprises a tile cover picking horizontal moving component 61, a tile cover picking lifting component 62, a swing table cylinder 63, a swinging air claw 64 and a tile cover picking single clamp 65.

[0040] In the above structure, the tile cover material taking horizontal moving assembly 61 is controlled by an electric cylinder, which can realize horizontal left and right movement, and can conveniently grab the tile cover 1 from the rotating table 71 through horizontal movement. The tile cover material taking lifting assembly 62 is mainly used to realize up and down movement, so as to send the tile cover 1 upward to the position of the tile cover installation mechanism 5. The swing table cylinder 63 can realize swinging, which can realize multi-angle control in conjunction with the tile cover material taking horizontal moving assembly 61 to facilitate the grabbing of the tile cover 1. The swinging air claw 64 mainly adopts a pneumatic structure to realize the grabbing and flipping of the tile cover 1.

[0041] As described above, for the tile cover 1 that needs to be press-fitted with the pin sleeve, the position of the tile cover 1 when the pin sleeve is pressed is exactly opposite to the position when the tile cover 1 is installed on the cylinder body 2. Therefore, the tile cover 1 needs to be flipped when it enters the installation position after being grabbed from the rotating table 71, and the flipping action is controlled by the above-mentioned swinging air claw 64. The tile cover picking mechanism 64 of the above-mentioned structure operates as follows: First, the tile cover picking horizontal moving component 61 translates to the position close to the rotating table 71, the swing table cylinder 63 swings to make the tile cover picking single clamp 65 enter the grabbing station, and the swinging air claw 64 moves to make the tile cover picking single clamp 75 clamp the tile cover 1, and then the tile cover picking horizontal moving component 61 moves to the direction close to the tile cover installation mechanism 5, the swing table cylinder 63 resets, the tile cover picking lifting component 62 moves upward, and the swinging air claw 64 moves to flip the tile cover 1. As the tile cover 1 moves upward, it enters the tile cover installation mechanism 5 and is fixed. After that, the tile cover picking mechanism 6 continues to grab the next tile cover 1.

[0042] In this embodiment, the tile cover installation mechanism 5 is mainly used to press the tile cover 1 onto the cylinder body 2. The tile cover installation mechanism 5 includes a tile cover installation lifting assembly 52 and a tile cover installation translation assembly 51. The tile cover installation lifting assembly 52 is mainly used to control the descent of the tile cover 1 so that it is pressed downward onto the cylinder body 2, and the tile cover installation translation assembly 51 is mainly used to adjust the horizontal position. Figure 1 A total of five tile covers 1 are installed on the cylinder body 2 shown. The positions of the five tile covers 1 are adjusted by means of a tile cover installation translation assembly 51, and the five tile covers 1 are installed on the cylinder body 2 one by one.

[0043] In this embodiment, the tile cover installation translation assembly 51 mainly includes a tile cover installation slide and a driving motor, the tile cover installation lifting assembly 52 is arranged on the tile cover installation slide, and the tile cover installation clamp assembly 53 is arranged under the installation slide and connected to the tile cover installation lifting assembly 52.

[0044] In this embodiment, the tile cover installation clamping claw assembly 53 mainly includes two tile cover installation clamping claw rods 531 and two clamping claw hanging plates 533. The tile cover installation clamping claw rods 531 are outside and the clamping claw hanging plates 533 are inside. The two clamping claw hanging plates 533 are connected to the finger cylinder 532. The finger cylinder 532 controls the relative movement of the two clamping claw hanging plates 533. When the tile cover 1 conveyed by the tile cover material taking mechanism 4 moves upward, the two tile cover installation clamping claw rods 531 are inserted into the two installation holes of the tile cover 1 for positioning, and then the finger cylinder 532 is operated to make the two clamping claw hanging plates 533 move to the bottom of the tile cover 1 to prevent the tile cover 1 from falling. When the tile cover installation lifting assembly 52 moves downward to the installation position of the cylinder body 2, the finger cylinder 532 is opened, and the tile cover 1 is installed to the corresponding position of the cylinder body 2. The above structure has the advantages of simple design and flexible movement.

[0045] In this embodiment, two sets of tile cover installation clamping assemblies 53 are arranged in parallel, and the two sets of tile cover installation clamping assemblies 53 have the same structure, but the spacing and size of the tile cover installation clamping rods 531 are different. The two sets of tile cover installation clamping assemblies 53 are respectively connected to independent tile cover installation lifting assemblies 52. Because the sizes of the tile covers 1 installed for different cylinder bodies 2 are slightly different, two sets of tile cover installation clamping assemblies 53 are designed so that the mechanism can realize the installation of two types of tile covers 1 of different sizes.

[0046] refer to Figure 9-13 The figure is a schematic diagram of the structure related to the rotating table and the pin sleeve press assembly provided in this embodiment.

[0047] The pin sleeve feeding track 10 adopts a vibration arrangement machine, through which the pin sleeves are arranged and then transported to the exit in sequence along the track. A pin sleeve dividing assembly 8 is arranged at the exit position of the pin sleeve feeding track 10, and the pin sleeves are arranged by the pin sleeve dividing assembly 8, which facilitates the pin sleeve pressing mechanism 9 to grab the pin sleeves.

[0048] The pin sleeve material dividing assembly 8 mainly includes a large material dividing cylinder 81, a small material dividing cylinder 82, a material dividing block 85 and a pin sleeve material dividing connecting plate 83, on which two pin sleeve receiving grooves 84 are arranged. In the above structure of this embodiment, the material dividing block 85 is swingably arranged at the exit position of the lower sleeve material feeding track 10 through a rotating shaft to prevent the pin sleeve from running backward. The small material dividing cylinder 82 is located on the large material dividing cylinder 81, and the pin sleeve material dividing connecting plate 83 is connected to the small material dividing cylinder 82.

[0049] The operation and use principle of the pin sleeve dividing assembly 8 are as follows: First, the large dividing cylinder 81 is actuated to drive the small dividing cylinder 82 and the pin sleeve dividing connecting plate 83 to move. When moving to the end of the stroke, the pin sleeve dividing connecting plate 83 pushes the dividing block 85 away and the pin sleeve receiving groove 84 on the left is just located at the exit of the pin sleeve feeding track 10. Under the vibration of the pin sleeve feeding track 10, a pin sleeve falls into the pin sleeve receiving groove 84. Then the small dividing cylinder 82 is actuated to move the pin sleeve dividing connecting plate 83. At the end of the stroke, the pin sleeve receiving groove 84 on the right moves just to the exit of the pin sleeve feeding track 10, and the second pin sleeve falls into the pin sleeve receiving groove 84 on the right. Then the small dividing cylinder 82 and the large dividing cylinder 81 are reset. At this time, there are two pin sleeves on the pin sleeve dividing connecting plate 83. The two positioned pin sleeves can be directly grabbed by the pin sleeve pressing mechanism 9 for installation.

[0050] In this embodiment, the rotating table mechanism 7 includes a rotating table 71, and the rotating table 71 is mainly used for positioning the tile cover 1 and switching the workstations. The bottom of the rotating table 71 is connected to a rotating table drive motor 73, and four groups of tile cover positioning assemblies 72 are arranged on the rotating table 71, and two sets are arranged in each group, and two different types of tile covers 1 can be installed. The tile cover positioning assembly 72 includes a rotating table tile cover positioning plate and two positioning shafts, and the positioning of the tile cover 1 is achieved through the positioning shafts. The rotating table 71 has four workstations in the circumference, and the switching of the four workstations is achieved by the rotation of the rotating table 71. When the rotating table 71 rotates to the pin sleeve press-fitting workstation, the pin sleeve is press-fitted at this workstation.

[0051] When the pin sleeve is pressed, the rotating table 71 is subjected to downward pressure. In order to ensure the stability of the structure, a rotating table support assembly is provided. The rotating table support assembly includes a rotating table support cylinder 76 and a lower inclined iron 75. An upper inclined iron 74 is provided below the rotating table 71. After the rotating table 71 moves to the right position, the rotating table support cylinder 76 is actuated to make the lower inclined iron 75 abut against the upper inclined iron 74 to realize stable support of the rotating table 71.

[0052] In this embodiment, the press-fitting of the pin sleeve is mainly completed by the pin sleeve press-fitting mechanism 9. Among them, the pin sleeve press-fitting mechanism 9 includes a pin sleeve press-fitting horizontal driving component 92, a pin sleeve press-fitting lifting driving component 91 and a pin sleeve press-fitting component 93. The pin sleeve press-fitting horizontal driving component 92 is used to drive the pin sleeve press-fitting component 93 to move horizontally, so that it grabs two pin sleeves from the pin sleeve material dividing plate 83 and moves to the top of the tile cover 1. The pin sleeve press-fitting lifting driving component 91 is used to drive the pin sleeve press-fitting component 93 to move downward to press the pin sleeve into the tile cover 1.

[0053] The pin sleeve press-fitting assembly 93 includes two press-fitting heads 931 and an auxiliary clamping assembly 932 arranged between the two press-fitting heads 931, wherein the auxiliary clamping assembly 932 includes a pin sleeve press-fitting auxiliary rod 9322 and an auxiliary rod spring 9321, which are used to clamp the tile cover 1 during press-fitting. The press-fitting head 931 includes a press-fitting head flange seat 9311, a press-fitting head core shaft 9312 and a material picking rod 9314. The press-fitting head core shaft 9312 is slidably arranged in the press-fitting head flange seat 9311 and is sleeved with a core shaft spring 9313 to enable the press-fitting head core shaft 9312 to achieve elastic pressing. The material picking rod 9314 is installed in the press-fitting head core shaft 9312. The material picking rod 9314 is a rod with a groove in the middle so that the two sides of the bottom have a certain elasticity. After the material picking rod 9314 is inserted into the pin sleeve, the pin sleeve is taken out from the pin sleeve material dividing plate 83 through the extrusion force of the two sides and the pin sleeve. After the pin sleeve is pressed into the tile cover 1, the friction between the pin sleeve and the tile cover 1 is large, so the material picking rod 9314 will not bring out the pin sleeve when it is pulled out.
