The first gear 33 is meshed with the rack plate 32 under force, so that the first motor 35 is forced to drive the movable plate 36 to move to one side. At the same time, the sliding plate 361 slides to one side inside the conveying groove 37, effectively ensuring a more stable movement of the movable plate 36. After reaching the positioned position, the first motor 35 is stopped; this is beneficial not only for conveying during assembly of the cylinder head, but also for conveying the finished cylinder head in the opposite direction after assembly, which can effectively improve functionality and practicality.

[0048] In this embodiment, the lifting mechanism 5 includes a second hydraulic cylinder 51 fixedly connected to the upper end surface of the conveying plate 43, the output end of the second hydraulic cylinder 51 is connected to a lifting rod 52, the upper end surface of the lifting rod 52 is connected to a bearing plate 53, both sides of the lower end surface of the bearing plate 53 are connected to limit rods 531, the lower ends of the limit rods 531 are inserted into the limit holes 431 on both sides of the inner side of the conveying plate 43, the upper end surface of the bearing plate 53 is provided with an adjustment groove 532, and both sides of the adjustment groove 532 are provided with a first L-shaped Groove 533 and a second L-shaped groove 534, a second gear 54 is connected to the middle of the upper end surface of the supporting plate 53 through a first fixing rod sleeve, the second gear 54 is meshed with a first tooth 55 and a second tooth 56, a side of the first tooth 55 is connected to a first L-shaped plate 551, the first L-shaped plate 551 is slidably connected to the inside of the first L-shaped groove 533, and the upper end surface of the first L-shaped plate 551 is fixedly connected to the first supporting plate 552, and the upper end surface of the first supporting plate 552 is provided with a first anti-slip pattern 553. When the cylinder head is lifted upward by the first support plate 552 and the second support plate 553, a small deviation occurs, and one side of the cylinder head first hits the first adjustment plate 6 or the second adjustment plate 62. After the side of the cylinder head first hits the first adjustment plate 6, the cylinder head is subjected to a reverse force to cause the first support plate 552 and the first L-shaped plate 551 to slide to one side inside the first L-shaped groove 533, wherein the first tooth 55 is engaged with the second gear 54, which allows the second gear 54 to rotate clockwise on the first fixing rod, and the second gear 54 is forced to engage with the second tooth 56, so that the first support plate 552 and the second support plate 553 can be displaced.

[0049] In this embodiment, one side of the second tooth 56 is connected to the second L-shaped plate 561, and the second L-shaped plate 561 is slidably connected to the inside of the second L-shaped groove 534, and the upper end surface of the second L-shaped plate 561 is fixedly connected to the second support plate 562, and the upper end surface of the second support plate 562 is provided with the second anti-slip groove 563. The first tooth 55 is meshed with the second gear 54, which allows the second gear 54 to rotate clockwise on the first fixing rod, and the second gear 54 is forcefully meshed with the second tooth 56, so that the second support plate 562 and the second L-shaped plate 561 slide in opposite directions inside the second L-shaped groove 534, so that the offset cylinder head can be gradually corrected. It is beneficial to utilize the first anti-slip groove 553 and the second anti-slip groove 563 to prevent the cylinder head from sliding during the movement of the first support plate 552 and the second support plate 562. After the cylinder head is offset, it can be automatically adjusted and corrected without human intervention, thereby speeding up the work progress and improving the functionality. Furthermore, the assembly accuracy of the cylinder head is improved, preventing the assembly work from not working properly due to offset, and improving work efficiency and practicality.

[0050] In this embodiment, a first butt plate 57 is connected to one side of the first L-shaped plate 551, and the first butt plate 57 is slidably matched with a first opening 571, and the first opening 571 is opened on the inner side wall of the first L-shaped groove 533; a second butt plate 58 is connected to one side of the second L-shaped plate 561, and a second butt plate 58 is slidably matched with a second opening 581, and the second opening 581 is opened on the inner side wall of the second L-shaped groove 534; one side of the first butt plate 57 and the second butt plate 58 are pressed against one side of the return block 362; the assembly grooves 59 are annularly and equiangularly opened on the upper end surface of the rotating circular plate 2, and one side of the conveying guide rail 44 extends to the lower end of the assembly groove 59. Start the first hydraulic cylinder 41 to return to the original position. Due to the adjustment of the offset cylinder head, the first support plate 552 and the second support plate 562 are in a misaligned state. Therefore, when returning to the original position, either the first abutment plate 57 or the second abutment plate 58 first abuts against one side of the return block 362, so that the first support plate 552 and the second support plate 562 can gradually return to the original state. After the first abutment plate 57 and the second abutment plate 58 both abut against the first abutment sensor 3621, stop the first hydraulic cylinder 41 to prepare for the conveying of the next cylinder head.

[0051] In this embodiment, a second conflict sensor 61 is disposed on one side of the first adjustment plate 6, and a third conflict sensor 63 is disposed on one side of the second adjustment plate 62, which is conducive to more accurate correction and subsequent assembly.

The first clamping assembly 74 includes a pull plate 741 transmission-connected to the elastic plate 73, and the pull plate 741 is connected to a clamping plate 742 through a second fixing rod. The lower end surface of the clamping plate 742 is fixedly connected to a guide plate 743, and the guide plate 743 is slidably matched with a guide groove 744.

The pull plates 741 are pulled by the clamping plate 742 and the pressure plate 745 to move toward the cylinder head, wherein the guide plate 743 is forced to slide inside the guide groove 744, which can ensure that the two pressure plates 745 are clamped more stably. At the same time, the two pressure plates 745 are gradually clamped on both sides of the cylinder head and fixed, which is conducive to clamping and fixing the cylinder head, and can avoid deviation and falling during assembly, thereby improving the protection of the cylinder head and the finished product efficiency of the cylinder head.

[0053] The method of using the cylinder head automatic assembly equipment for engine manufacturing is as follows:

[0054] S1, first conveying: the cylinder head is placed on the placing plate rack 363 by a manipulator, and the movable plate 36 is moved to one side to the positioned position under the output of the first motor 31, so that the work of loading (cylinder head) and taking out the cylinder head can be effectively realized;

[0055] S2, rising: using the output of the second hydraulic cylinder 51, the bearing plate 53, the first supporting plate 552, and the second supporting plate 562 are moved upward, and the first supporting plate 552 and the second supporting plate 552 gradually lift the cylinder cover upward, and then the cylinder cover is lifted to the positioning position, and the second hydraulic cylinder 51 can be stopped, so that the cylinder cover can be lifted stably;

[0056] S3, second conveying: through the output of the first hydraulic cylinder 41, the conveying plate 43 slides to one side inside the conveying guide rail 11, which also drives the first support plate 552, the second support plate 562, and the cylinder cover to move toward the assembly port 11. This work does not require the use of a manipulator;

[0057] S4, adjustment: if the cylinder head has a deviation problem, the first adjustment plate 6 or the second adjustment plate 62 is used to press the first support plate 552 and the second support plate 562 to move the first support plate 552 and the second support plate 562, so that the cylinder head can be automatically corrected. This work does not require manual participation and speeds up the work progress;

[0058] S5, descending: under the signal transmission of the second contact sensor 61 and the third contact sensor 63, the second hydraulic cylinder 51 is started, and the first support plate 552, the second support plate 553 and the cylinder head are driven downward by the output of the second hydraulic cylinder 51, so that the cylinder head is gradually and slowly placed on the assembly groove 59. In this work, there is no need for the manipulator to load the material (cylinder head);

[0059] S6, clamping: through the output of the second motor 71, the tension plate 73 is pulled on the pull plates 741 on both sides, and the pull plates 741 are pulled by the clamping plates 742 and the pressure plates 745, and the two pressure plates 745 are gradually clamped on both sides of the cylinder head and fixed, effectively avoiding the problem of deviation and falling during assembly;

[0060] S7, assembly: After the cylinder head is clamped and fixed, it is assembled with the sleeve device 13, the screw plug device 14, the bowl plug device 15, and the damping pin device 16 in sequence through the rotation of the rotating circular plate 2, and then transported to the finished product port 12;

[0061] S8, taking out: the unloading work is completed through the adjacent conveying mechanism, feeding mechanism and lifting mechanism, wherein the cylinder head is first lifted by the lifting mechanism, and then the feeding mechanism is started to transport the lifted cylinder head outward, and when it reaches the upper end of the placement plate rack on the conveying mechanism, the lifting mechanism is started to place the cylinder head on the placement plate rack, thereby realizing the work of taking out the cylinder head.

[0062] The specific working principle of the present invention includes the following process:

[0063] First, the cylinder head is placed on the upper end surface of the plate rack 363 (such as Figure 1 As shown), after placement, start the first motor 35 to drive the first rotating shaft 34 to drive the first gear 33 to rotate counterclockwise, and the first gear 33 is meshed with the rack plate 32 by force, so that the first motor 35 is forced to drive the movable plate 36 to move to one side, and at the same time, the sliding plate 361 slides to one side inside the conveying groove 37. After reaching the positioning position (positioning work is performed in advance by the controller), stop the first motor 35. At this time, start again, the second hydraulic cylinder 51 drives the lifting rod 52 to drive the bearing plate 53 to move upward, and then the bearing plate 53 moves upward, driving the limiting rod 531 to slide upward inside the limiting hole 431. At the same time, the bearing plate 53 drives the first L-shaped plate 551, the second L-shaped plate 561, the first supporting plate 552, and the second supporting plate 562 to move upward, and the upper end surfaces of the first supporting plate 552 and the second supporting plate 552 gradually lift the cylinder cover. After the cylinder cover is lifted upward and lifted to the positioning position, the second hydraulic cylinder can be stopped.

[0064] Then start the first hydraulic cylinder 41 to drive the conveying rod 42 to press against the conveying plate 43 to one side. The conveying plate 43 is forced to slide to one side inside the conveying guide rail 11, and the conveying plate 43 drives the cylinder head on the first support plate 552 and the second support plate 562 to move toward the assembly port 11. After the cylinder head reaches the assembly port 11, one side of the cylinder head will first contact the first adjustment plate 6 and the second adjustment plate 62. If the cylinder head is lifted upward by the first support plate 552 and the second support plate 553, and there is a small deviation, one side of the cylinder head will first contact the first adjustment plate 6 or the second adjustment plate 62. After one side of the cylinder head first contacts the first adjustment plate 6, the cylinder head is The reverse force causes the first support plate 552 and the first L-shaped plate 551 to slide to one side inside the first L-shaped groove 533, wherein the first tooth 55 is meshed with the second gear 54, which causes the second gear 54 to rotate clockwise on the first fixing rod, and the second gear 54 is meshed with the second tooth 56 under force, causing the second support plate 562 and the second L-shaped plate 561 to slide in opposite directions inside the second L-shaped groove 534, so that the offset cylinder head can be gradually corrected, wherein the friction between the second anti-slip groove 563 and the first anti-slip groove 553 and the weight of the cylinder head itself will not cause the cylinder head to tip over or slide to one side, and the cylinder head can only be rotated in situ to correct the position.

[0065] After adjusting the position again (at this time, the cylinder head is located at the upper end of the assembly groove 59), one side of the cylinder head contacts the first adjustment plate 6 and the second adjustment plate 62. At this time, the second contact sensor 61 and the third contact sensor 63 have received signals, and their signals are transmitted to the controller. After receiving the signals, the controller stops the first hydraulic cylinder 41 and starts the second hydraulic cylinder 51 to drive the lifting rod 52 downward to drive the bearing plate 53, the first support plate 552, the second support plate 553, and the cylinder head until the lower end surface of the cylinder head is placed in the assembly groove 59, and then continues to move downward. Lower the first support plate 552 and the second support plate 553 to their original positions to stop the second hydraulic cylinder 41. At the same time, after the cylinder head is placed in the assembly groove 59, start the second motor 71 to drive the second rotating shaft 72 to rotate the tension plate 73 clockwise to pull the pulling plates 741 on both sides. The pulling plate 741 is pulled by the clamping plate 742 and the pressure plate 745 to move toward the cylinder head, wherein the guide plate 743 is forced to slide inside the guide groove 744. At the same time, the two pressure plates 745 are gradually clamped on both sides of the cylinder head and fixed.

[0066] After fixing the cylinder head, start the driving device 22 to allow the multiple transmission plates 21 to drive the rotating circular plate 2 to rotate inside the assembly circular box 1, thereby allowing the newly fixed cylinder head to rotate in the direction of the assembly sleeve device 13. At this time, start the first hydraulic cylinder 41 to return to the original position. Due to the adjustment of the offset cylinder head, the first support plate 552 and the second support plate 562 are in a misaligned state. Therefore, when returning to the original position, either the first abutment plate 57 or the second abutment plate 58 first abuts against one side of the return block 362, so that the first support plate 552 and the second support plate 562 can gradually return to their original states. After the first abutment plate 57 and the second abutment plate 58 both abut against the first abutment sensor 3621, stop the first hydraulic cylinder 41 to prepare for the transportation of the next cylinder head.

[0067] After the cylinder head is assembled with the sleeve device 13, the screw plug device 14, the bowl plug device 15 and the damping pin device 16 in sequence, it is transported to the finished product port 12, and then passes through the adjacent conveying mechanism, loading mechanism and lifting mechanism to complete the unloading work. This work is the same as the above work (the working and conveying direction is opposite), the difference is that there is no first adjustment plate 6 and the second adjustment plate 62, and automatic loading and removal of the cylinder head is realized.

[0068] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
