Description

TECHNICAL FIELD

[0001] The present application relates to the engine cylinder block processing technical field, especially to a kind of auxiliary component circulation turnover equipment for engine cylinder block processing. BACKGROUND

[0002] In the engine cylinder block processing process, many links have higher requirements for the efficiency, stability and automation degree of equipment. Among them, the turnover of auxiliary components for engine cylinder block processing, such as the assembly and disassembly of accompanying brackets, simulated cylinder covers and lower cylinder blocks, is a key factor affecting processing efficiency and cost.

[0003] In traditional engine cylinder block processing, some products need to be assembled with these auxiliary components in specific processes. For example, the patent document with the authorized announcement number "CN106239058B" discloses a "process cylinder cover removal equipment and process cylinder cover disassembly and circulation line". Although it realizes semi-automatic processing line layout for process cylinder cover installation and disassembly at relatively low cost, it improves processing efficiency, reduces processing error rate and reduces regional layout cost to a certain extent. However, in actual operation, this technology still has obvious shortcomings. The turnover process of auxiliary components is relatively complex. For example, when connecting different processes, the robot needs to be compatible with multiple different process feeding and discharging work, which causes tight rhythm and makes it difficult to further improve processing efficiency, so that the capacity of cylinder block finishing cannot be fully utilized. At the same time, the participation of manual work is high. At least two operators are needed in the process of assembling and transporting auxiliary components, which not only increases labor cost, but also greatly increases labor intensity of employees.

[0047] Embodiment 1

[0048] Please see Figure 1 The embodiments of the present application provide a kind of auxiliary component circulation turnover equipment for engine cylinder machining;In the processing and manufacturing process of engine cylinder 5000, in order to ensure the accuracy and stability of cylinder, some specific auxiliary components 4000 are often needed to cooperate with the use of engine cylinder 5000.For example, when engine cylinder 5000 is processed, part of product must be equipped with auxiliary operation such as cylinder, simulation cylinder cover or accompanying bracket.The use of these auxiliary components 4000 is to better fix and support cylinder, ensure the accuracy and consistency in processing process.

[0049] The conventional assembly method mainly relies on manual operation, specifically, workers need to manually install the auxiliary components 4000 on the engine cylinder block 5000. This not only means that manual and tedious installation work is required, but also requires special staff to be arranged to disassemble these auxiliary components 4000 after processing is completed and to transport them to the next assembly process. In this process, at least two operators are required to cooperate to complete the disassembly, transportation and installation of the auxiliary components 4000; these auxiliary components 4000 themselves have a certain weight, and workers not only consume a lot of physical strength when assembling and transporting, but also increase the labor intensity due to the weight burden. This high-intensity physical labor not only affects work efficiency, but also can cause certain damage to the health of employees. Therefore, how to reduce the labor burden of employees while ensuring the processing quality has become a problem to be solved.

[0050] Therefore, in the present embodiment, an engine cylinder block processing auxiliary component circulation turnover equipment is provided, which automatically completes the disassembly, transportation and installation of the auxiliary components 4000 by the equipment, thereby effectively reducing manual intervention and improving overall work efficiency.

[0051] Further, please refer to Figure 1 , Figure 2 and Figure 3 , the circulation turnover equipment comprises a first working device 1000 and a second working device 2000 which are centrally symmetrically arranged, and a conveying device 3000 connecting the first working device 1000 and the second working device 2000; the first working device 1000 comprises a rack 1100, a grabbing mechanism 1200 and a lifting mechanism 1300.

[0052] Please refer to Figure 1 and Figure 2The rack 1100 is composed of square tubes and forms a working space; the grabbing mechanism 1200 is arranged on the top of the rack 1100 and is used for grabbing auxiliary parts 4000 for machining the engine cylinder block 5000, and comprises a jaw base plate 1240 and clamping parts 1250 symmetrically arranged on both sides of the jaw base plate 1240; the jaw base plate 1240 can move laterally based on the rack 1100; the lifting mechanism 1300 is arranged on one side of the rack 1100 and comprises a lifting platform 1320, which can move up and down based on the rack 1100; wherein the first working device 1000 is used for disassembling the auxiliary parts 4000 from the engine cylinder block 5000, the second working device 2000 is used for mounting the auxiliary parts 4000 on the engine cylinder block 5000, and the conveying device 3000 is used for conveying the auxiliary parts 4000 disassembled by the first working device 1000 to the second working device 2000.

[0053] Further, the structures of the first working device 1000 and the second working device 2000 are consistent.

[0054] Please refer to Figure 2 In use, first, the engine cylinder block 5000, which has completed preliminary machining and needs to be disassembled auxiliary parts 4000 next, is placed in the first working device 1000 at a pre-set machining position. In this process, the engine cylinder block 5000 is placed in a posture so that the auxiliary parts 4000 are just on the top of the engine cylinder block 5000, to facilitate the smooth operation of the subsequent operation. Next, the grabbing mechanism 1200 is used to grab the auxiliary parts 4000 and place them securely on the lifting mechanism 1300. Through the movement of the lifting mechanism 1300, the grabbed auxiliary parts 4000 are safely placed on the conveying device 3000. Then, with the transmission function of the conveying device 3000, the auxiliary parts 4000 are smoothly conveyed to the second working device 2000.

[0055] At the second working device 2000, the auxiliary parts 4000 are moved to a position where they can be easily grabbed by the grabbing mechanism 1200 through the lifting mechanism 1300 of the device. Again, the grabbing mechanism 1200 is used to firmly grab the auxiliary parts 4000 and move them to the top of the engine cylinder block 5000 according to the predetermined path for installation.

[0056] This series of automatic operation steps, through strict operation specification and technical guidance, ensures that the disassembly and installation process of the auxiliary component 4000 is not only efficient but also accurate, greatly improving work efficiency and fundamentally guaranteeing the smooth operation and high-quality output of the entire engine cylinder block 5000 machining process. In this way, errors and uncertainties caused by manual intervention are effectively avoided, and the problem of excessive labor intensity of manual assembly and disassembly of the engine cylinder block 5000 is also avoided.

[0057] Further, the auxiliary components 4000 (such as traveling carriages, simulated cylinder covers, lower cylinder blocks, etc.) in the machining of the engine cylinder block 5000 need to be recycled, the fundamental reason being the special nature of their functions and the necessity of cost control. These auxiliary components 4000 are not disposable consumables, but are used to support, position, or simulate assembly environments during the machining process, such as traveling carriages that need to carry the cylinder block through different workstations, simulated cylinder covers for testing sealing performance, etc. If not recycled, new components need to be replaced each time, which not only significantly increases procurement costs, but also leads to a decline in production efficiency due to frequent disassembly and assembly of new components. In addition, recycling ensures that the mating precision of the components and the cylinder block remains consistent, avoiding the impact of tolerance differences in new components on machining quality, while reducing waste generation, meeting the dual requirements of green and economic industrial production.

[0058] In the present application, the conveying device 3000 is provided to realize the recycling of the auxiliary components 4000, which has the advantage of constructing a closed-loop transfer system through automated logistics design, so that the disassembled auxiliary components 4000 in the first working device 1000 can be automatically returned to the installation station in the second working device 2000 through the conveying device 3000, avoiding time loss and process interruption caused by manual handling, and significantly improving production continuity.

[0059] Please refer to Figure 2 In the present embodiment, the first working device 1000, the conveying device 3000 and the second working device 2000 form an efficient recycling link of "disassembly-conveying-installation", not only saving the physical consumption of manual transfer, but also reducing the risk of surface damage caused by handling through reducing human intervention in the process of parts turnover, ensuring the accuracy and reliability of the repeated use of parts, and achieving effective reduction of production cost from the dual dimensions of process optimization and quality control.

[0060] Further, please refer to Figure 1 and Figure 2The conveying device 3000 is arranged at the bottom of the first working device 1000 and the second working device 2000; both sides of the conveying device 3000 are provided with conveying chains 3100 for synchronous conveying operation; both sides of the conveying device 3000 are also provided with limiting plates 3200 for limiting the position of the auxiliary components 4000; the auxiliary components 4000 are conveyed by the conveying chains 3100.

[0061] The main function of the conveying device 3000 is to effectively avoid the cumbersome process of manually disassembling the auxiliary components 4000 and then carrying them one by one to another processing device, thereby ensuring the continuity and uninterruptedness of the entire working process.

[0062] This design not only greatly improves the work efficiency, but also fundamentally solves the problem of downtime caused by manual carrying. In addition, the conveying device 3000 also has an important function, which can significantly reduce the risk of bumps, friction or other forms of damage to the auxiliary components 4000 during the carrying process. This feature not only effectively protects the integrity of the auxiliary components 4000, but also further improves the stability and safety of the entire processing process, ensuring the smooth progress of the production process.

[0063] At the same time, the design of the limiting plate 3200 also plays a crucial role. It ensures that the auxiliary components 4000 can always maintain the correct posture and accurate position during the conveying process, effectively avoiding the occurrence of problems such as conveying failure or equipment jamming caused by component deviation. This fine design not only improves the reliability of conveying, but also greatly reduces the failure rate caused by improper position.

[0064] This highly automated conveying method not only fundamentally optimizes the rhythm and process of the entire operation, but also significantly reduces the need for manual intervention. Through intelligent control, the entire production process becomes more efficient and intelligent, greatly improving production efficiency and product quality. In addition, the conveying system also adopts the synchronous conveying operation design of double-sided conveying chains 3100, which can greatly improve the conveying efficiency and provide more reliable and stable support for subsequent processing links, ensuring the smooth operation and high output of the entire production line.

[0065] Further, please refer to Figure 3 , Figure 4 and Figure 5Since the engine cylinder block 5000 needs to be placed in a specified machining position when assembling and disassembling, in order to ensure the continuity of machining and reduce the labor intensity of manual work, in the embodiment, the first working device 1000 is also provided with a conveying mechanism 1400 for conveying the engine cylinder block 5000; the conveying mechanism 1400 is arranged on the rack 1100, and first limiting assemblies 1500 are arranged on both sides of the conveying mechanism 1400, and second limiting assemblies 1600 are arranged on both sides of the end of the conveying mechanism 1400; the conveying mechanism 1400 is used to input or output the engine cylinder block 5000 after the auxiliary component 4000 is disassembled or installed or before the auxiliary component 4000 is disassembled or installed.

[0066] When the auxiliary component 4000 needs to be disassembled, the first working device 1000 inputs the engine cylinder block 5000 that needs to be disassembled through the conveying mechanism 1400, moves the engine cylinder block 5000 to a predetermined machining position, then limits the position of the engine cylinder block 5000 through the first limiting assemblies 1500 and the second limiting assemblies 1600 to avoid displacement of the engine cylinder block 5000, then disassembles the auxiliary component 4000 on the engine cylinder block 5000 through the grabbing mechanism 1200 and the lifting mechanism 1300, and outputs the engine cylinder block 5000 after disassembly through the conveying mechanism 1400, and then inputs the next engine cylinder block 5000 that needs to be disassembled to realize the continuity of the entire disassembly process.

[0067] When the auxiliary component 4000 needs to be installed, the second working device 2000 conveys the engine cylinder block 5000 that needs to install the auxiliary component 4000 to a specified machining position, and installs the auxiliary component 4000 on the engine cylinder block 5000 through the lifting mechanism 1300 and the grabbing mechanism 1200, and then conveys the engine cylinder block 5000 away after installation, and then inputs the next engine cylinder block 5000 that needs to install the auxiliary component 4000 to realize the continuity of the entire installation process.

[0068] Further, when facing engine blocks 5000 with different heights, the fixed-height grabbing mechanism 1200 is difficult to directly and accurately grab or install the auxiliary components 4000, therefore, in the embodiment, a lifting mechanism is arranged in the conveying mechanism 1400, which compensates for the limitation of the fixed height of the grabbing mechanism 1200 to adapt to engine blocks 5000 with different heights. The lifting mechanism includes a first lifting mechanism 1800 and a second lifting mechanism 1900, which can drive the lifting driving plate and the guide rod to rise and fall through the first lifting cylinder 1810 and the second lifting cylinder 1910, so that the engine block 5000 is lifted to a position consistent with the height of the grabbing mechanism 1200, and the grabbing mechanism 1200 can complete the standardized disassembly and assembly operation in the same height plane, thereby breaking through the limitation of the height difference of the block, realizing the universal adaptation of various models of engine blocks 5000, and improving the processing compatibility and automatic adaptation ability of the equipment.

[0069] In the embodiment, please refer to Figure 5 and Figure 7 , the bottom of the conveying mechanism 1400 is also provided with a first lifting mechanism 1800 through a lifting fixing plate 1420, the first lifting mechanism 1800 includes a first lifting cylinder 1810 and a first lifting driving plate 1820 connected with the first lifting cylinder 1810; a plurality of first guide rods 1830 are arranged on the first lifting driving plate 1820, the first guide rods 1830 can move based on a first sleeve 1431 arranged on the lifting fixing plate 1420; and a plurality of the first guide rods 1830 can pass through the interval between the conveying rollers 1410 of the conveying mechanism 1400 and extend.

[0070] Further, please refer to Figure 7 , the bottom of the conveying mechanism 1400 is also provided with a second lifting mechanism 1900 through the lifting fixing plate 1420, the second lifting mechanism 1900 is arranged between the lifting fixing plate 1420 and the first lifting driving plate 1820; the second lifting mechanism 1900 includes a second lifting cylinder 1910 and a second lifting driving plate 1920 connected with the second lifting cylinder 1910; a plurality of second guide rods 1930 are arranged on the second lifting driving plate 1920, the second guide rods 1930 can move based on a second sleeve 1432 arranged on the lifting fixing plate 1420; and a plurality of the second guide rods 1930 can pass through the interval between the conveying rollers 1410 of the conveying mechanism 1400 and extend.

[0071] The first lifting mechanism 1800 and the second lifting mechanism 1900 are arranged to meet the requirements of stability and accurate positioning of the engine cylinder block 5000 during transportation and assembly. The first lifting mechanism 1800 is composed of a first lifting cylinder 1810, a first lifting driving plate 1820, and a first guide rod 1830, which is connected to the bottom of the transportation mechanism 1400 through a lifting fixed plate 1420, and the first guide rod 1830 can extend through the interval between the transportation rollers 1410. Such a structure can smoothly lift the cylinder block after it is transported to the designated position, so that the cylinder block is separated from the transportation rollers 1410, avoiding the interference of the rotation of the transportation rollers 1410 with the assembly process, and providing a stable grasping plane for the grasping mechanism 1200, ensuring that the position of the cylinder block is fixed during the disassembly or installation of the auxiliary component 4000, and preventing assembly errors caused by the shaking of the cylinder block.

[0072] The coordinated action of the two lifting mechanisms can realize reliable support and height adjustment of the cylinder block. The second lifting mechanism 1900 is arranged between the lifting fixed plate 1420 and the first lifting driving plate 1820, and is also composed of a second lifting cylinder 1910, a second lifting driving plate 1920, and a second guide rod 1930, forming a symmetrical support structure with the first lifting mechanism 1800.

[0073] This bilateral lifting design can evenly distribute the stress on the cylinder block, avoiding the tilting or deformation of the cylinder block caused by single-point lifting, especially when facing cylinder blocks of different weights or sizes, the synchronous lifting of the two mechanisms can ensure the levelness of the cylinder block. At the same time, the combination of the two mechanisms can improve the stability and precision of the lifting process, and the guiding action of the guide rods and sleeves can make the lifting height of the cylinder block more accurate, meet the adaptation requirements of the grasping mechanism 1200 to cylinder blocks of different heights, and effectively enhance the processing adaptability and reliability of the equipment to various types of cylinder blocks.

[0074] When installing the auxiliary component 4000, the working principle of the lifting mechanism (the first lifting mechanism 1800 and the second lifting mechanism 1900) is as follows: when the engine cylinder block 5000 is transported to the designated position, the first lifting cylinder 1810 and the second lifting cylinder 1910 are started synchronously, the piston rods of the first lifting cylinder 1810 and the second lifting cylinder 1910 are extended, pushing the first lifting driving plate 1820 and the second lifting driving plate 1920 to move upwards, driving the first guide rod 1830 and the second guide rod 1930 to extend upwards through the interval between the transportation rollers 1410, smoothly lifting the cylinder block. At this time, the cylinder block is separated from the transportation rollers 1410 and is lifted to a position consistent with the height of the grasping mechanism 1200, facilitating the grasping mechanism 1200 to precisely dock the positioning structure such as the pin hole on the cylinder block with the auxiliary component 4000 (such as a traveling bracket), completing the installation of the auxiliary component 4000. After installation, the piston rods of the lifting cylinders are retracted, driving the lifting driving plates and guide rods to descend, and the cylinder block falls back onto the transportation rollers 1410, which are then transported away by the transportation mechanism 1400.

[0075] When disassembling the auxiliary component 4000, the operation logic of the lifting mechanism (the first lifting mechanism 1800 and the second lifting mechanism 1900) is as follows: after the cylinder is transported to the position, the lifting mechanism lifts the cylinder through the driving of the air cylinder, so that the auxiliary component 4000 (such as the accompanying bracket) is kept in a suspended state with the cylinder, facilitating the movement of the grabbing mechanism 1200 above the auxiliary component 4000 for grabbing. After the grabbing mechanism 1200 clamps the auxiliary component 4000, the lifting mechanism starts to descend, and the cylinder falls with it, while the auxiliary component 4000 is fixed by the grabbing mechanism 1200. Due to the descent of the cylinder, the positioning pins and other connecting structures between the auxiliary component 4000 and the cylinder gradually disengage, and finally rely on the action of gravity, the auxiliary component 4000 and the cylinder are completely separated. At this time, the lifting mechanism stops descending, and the grabbing mechanism 1200 can carry the auxiliary component 4000 to the conveying device 3000, completing the disassembly process. The whole process realizes the separation of the auxiliary component 4000 and the cylinder through the lifting and descending actions of the lifting mechanism, reducing manual intervention and operation difficulty.

[0076] Further, please refer to Figure 7 , the top of the first guide rod 1830 is provided with a lifting pad 1840, and the top of the second guide rod 1930 is also provided with a lifting rod 1940, and the lifting rod 1940 is arranged at least through two second guide rods 1930; the lifting pad 1840 is made of wear-resistant and elastic material, which can provide buffering effect when contacting the bottom of the cylinder, avoiding damage to the surface of the cylinder caused by rigid contact. At the same time, the design of the lifting rod 1940 enhances the supporting strength of the second lifting mechanism 1900, which is fixed through two or more second guide rods 1930, ensuring stability during lifting and avoiding deviation due to uneven stress. This design not only improves the reliability of the lifting system, but also effectively disperses the weight of the cylinder, reduces local stress concentration, prolongs the service life of the equipment and ensures the safety of operation. In addition, the combination of the lifting pad 1840 and the lifting rod 1940 makes the cylinder more accurately dock with the grabbing mechanism 1200 after being lifted to the target height, providing higher position accuracy and operation convenience for the subsequent assembly link.

[0077] Further, please refer to Figure 4 and Figure 5The lifting mechanism 1300 comprises a pair of lifting guide rods 1310 arranged on the rack 1100 and a lifting platform 1320 arranged on the lifting guide rods 1310; the lifting platform 1320 is provided with a first mounting plate 1331 and a second mounting plate 1332 arranged at intervals, and the first mounting plate 1331 and the second mounting plate 1332 are provided with a detachable receiving plate 1333; the receiving plate 1333 is provided with a mounting hole 1335 for mounting a positioning pin 1334; and the lifting platform 1320 is driven by a lifting cylinder 1336.

[0078] When the lifting cylinder 1336 is driven, the lifting platform 1320 moves up and down along the pair of lifting guide rods 1310 on the rack 1100. When the receiving auxiliary component 4000 is needed, the piston rod of the lifting cylinder 1336 is extended to drive the lifting platform 1320 to rise along the guide rod to the specified position, at which time the grabbing mechanism 1200 places the auxiliary component 4000 on the receiving plate 1333 of the lifting platform 1320, and the receiving plate 1333 is positioned by the positioning pin 1334 in the mounting hole 1335 and cooperates with the positioning hole on the auxiliary component 4000 to realize accurate positioning of the auxiliary component 4000; when the auxiliary component 4000 needs to be placed, the piston rod of the lifting cylinder 1336 is retracted, the lifting platform 1320 is lowered along the guide rod, and the auxiliary component 4000 is placed on the conveying track or the specified station. The height of the lifting platform 1320 is controlled by the extension and retraction of the lifting cylinder 1336, and the stability and guiding accuracy of the lifting process are ensured by the lifting guide rods 1310.

[0079] Further, in the installation of the auxiliary component 4000, when the auxiliary component 4000 placed on the conveying device 3000 is obtained, the lifting platform 1320 of the lifting mechanism 1300 needs to be moved to the position first, and then the auxiliary component 4000 is conveyed by the conveying device 3000 into the lifting platform 1320 to ensure that the auxiliary component 4000 is in a correct posture for installation.

[0080] Please refer to Figure 4, the cooperation of the lifting guide rod 1310 and the lifting cylinder 1336 ensures that the lifting platform 1320 remains horizontal during lifting, avoiding tilting or shaking of the auxiliary component 4000, and ensuring accurate docking of the positioning pin 1334 with the positioning hole of the auxiliary component 4000; the receiving plate 1333 is detachably arranged on the first mounting plate 1331 and the second mounting plate 1332, facilitating replacement of different specifications of receiving plates 1333 according to the size and positioning needs of different auxiliary components 4000, improving the adaptability of the equipment to various auxiliary components 4000; the positioning pin 1334 and the mounting hole 1335 are provided to achieve precise positioning of the auxiliary component 4000 on the lifting platform 1320, providing a stable reference for subsequent grabbing or mounting actions of the grabbing mechanism 1200, effectively improving the precision and reliability of disassembly and assembly of the auxiliary component 4000, and reducing manual operation through automatic driving of the lifting cylinder 1336, improving production efficiency.

[0081] Further, please refer to Figure 4 and Figure 6 , the grabbing mechanism 1200 includes a pair of moving guide rods 1210 arranged on the top of the rack 1100, and a moving platform 1220 arranged on the moving guide rods 1210; the moving platform 1220 is driven by a rodless cylinder unit 1260 arranged on one side of the top of the rack 1100. The rodless cylinder unit 1260 includes a driving guide rod 1261 and a movable connecting part 1262 based on the driving guide rod 1261; the connecting part 1262 is connected with the moving platform 1220 through a connecting rod 1263 and drives the moving platform 1220 to move on the moving guide rod 1210.

[0082] The driving core of the grabbing mechanism 1200 is the coordinated operation of the rodless cylinder unit 1260 and the moving guide rod 1210. When the compressed gas in the rodless cylinder unit 1260 pushes the driving guide rod 1261, the connecting part 1262 makes linear reciprocating motion on the driving guide rod 1261, and the moving platform 1220 is driven by the connecting rod 1263 to slide horizontally along the moving guide rod 1210 on the top of the rack 1100. For example, when disassembling the auxiliary component 4000, the rodless cylinder drives the moving platform 1220 to move towards the engine block 5000, so that the grabbing mechanism 1200 is positioned above the target component; when installing, it moves in the opposite direction, and the component is transported to the designated station. The moving guide rod 1210 provides rigid support and guidance for the moving platform 1220, ensuring the stability and trajectory accuracy of the moving process, and realizing the precise displacement of the grabbing mechanism 1200 between different stations.

[0083] The working principle of the rodless cylinder is to realize linear motion through non-contact transmission of the internal piston and the driving guide rod 1261. In its internal structure, the piston moves along the cylinder axis under the action of gas pressure, and the driving guide rod 1261 is linked with the piston through magnetic coupling or mechanical connection to form linkage, so that the connecting part 1262 moves synchronously with the piston. Compared with the traditional rod cylinder, the rodless cylinder omits the structure of the protruding rod, and through the slot or built-in guide rail on the side of the cylinder body, the connecting part 1262 directly drives the load, avoiding the problems of space occupation and motion interference caused by the exposure of the piston rod, and at the same time, it has higher stroke utilization rate and protection performance, which is suitable for driving the grabbing mechanism 1200 to move high-frequency reciprocating in the compact rack 1100 top space.

[0084] Please refer to Figure 4 , the design significantly improves the motion efficiency and space adaptability of the grabbing mechanism 1200 through the combination of the rodless cylinder and the moving guide rod 1210. On the one hand, the rodless structure of the rodless cylinder reduces the horizontal space occupation of the equipment, making the layout of the rack 1100 top more compact, which is suitable for the dense station arrangement of the engine cylinder body 5000 processing line; on the other hand, the parallel arrangement of the moving guide rod 1210 and the driving guide rod 1261 forms a stable double-track support, which can withstand the lateral force when the grabbing component is grabbed, avoiding the shaking of the moving platform 1220, and ensuring the positioning accuracy of the clamping action. In addition, the high-speed response characteristics of the rodless cylinder (such as rapid start-stop and adjustable speed) can match the beat requirements of the automated production line, so that the grabbing mechanism 1200 can realize rapid positioning in the disassembly and assembly process, improve the overall production efficiency, and reduce the mechanical wear and maintenance cost.

[0085] Further, please refer to Figure 5 , the moving platform 1220 is connected with the clamping jaw substrate 1240 through the connecting column 1230; the clamping part 1250 is connected with the clamping jaw substrate 1240 through the clamping jaw mounting plate 1251; the clamping part 1250 includes a clamping jaw cylinder 1252 and a fixed rod 1253 arranged at the bottom of the clamping jaw substrate 1240; the piston rod of the clamping jaw cylinder 1252 is hinged with a clamping jaw 1254, the other end of the clamping jaw 1254 is hinged with the fixed rod 1253 through a first connecting rod 1255 and a second connecting rod 1256; the clamping jaw 1254 can realize clamping or releasing action through the elongation or shortening of the piston rod of the clamping jaw cylinder 1252.

[0086] In use, when the piston rod of the clamping cylinder 1252 is elongated, the clamping jaw 1254 is pushed to rotate around the hinge point, and the first connecting rod 1255 and the second connecting rod 1256 are linked to tighten the end of the clamping jaw 1254 inward, thereby completing the clamping action on the workpiece; when the piston rod is shortened, the clamping jaw 1254 is opened outward under the action of the connecting rod mechanism, releasing the workpiece. Through the simultaneous operation of a pair of said clamping parts 1250, the clamping part 1250 can stably clamp the auxiliary part 4000; this design converts linear motion into rotary motion of the clamping jaw 1254 through the connecting rod mechanism, not only enhancing the transmission efficiency of the clamping force, but also ensuring the stability and reliability of the clamping action. In addition, the fixed rod 1253 provides additional support for the entire clamping part 1250,

[0087] Further, please refer to Figure 10 The first limiting assembly 1500 includes a first limiting cylinder 1510 and a limiting rod connected to the piston rod of the first limiting cylinder 1510, and the end of the limiting rod is further provided with a limiting push rod 1530.

[0088] In use, when the piston rod of the first limiting cylinder 1510 is elongated, the limiting rod is pushed to move forward, and the limiting push rod 1530 acts to accurately position and limit the target workpiece, so as to limit the deviation of the engine cylinder block 5000 to both sides on the conveying mechanism 1400. This design can also effectively prevent the workpiece from deviating or shaking during clamping, thereby improving the accuracy and stability of the overall operation. The position of the limiting push rod 1530 can be adjusted according to actual needs to ensure that it adapts to workpieces of different sizes and shapes.

[0089] Further, please refer to Figure 9 The second limiting assembly 1600 includes a second limiting cylinder 1610 and a first rotating plate 1620 connected to the piston rod of the second limiting cylinder 1610, and the other end of the first rotating plate 1620 is connected with a second limiting base plate 1650; the second limiting assembly 1600 further includes a bushing 1640 arranged on the conveying mechanism 1400, and the second limiting base plate 1650 is connected with the bushing 1640 through a second rotating plate 1630; the second limiting cylinder 1610 drives the second limiting base plate 1650 to rotate based on the bushing 1640 through the extension or shortening of the piston rod, so as to release or limit the movement of the engine cylinder.

[0090] In use, when the piston rod of the second limiting cylinder 1610 extends, the first rotating plate 1620 rotates accordingly, and drives the second limiting base plate 1650 to rotate around the bushing 1640. This rotating action enables the second limiting assembly 1600 to accurately adjust the position, thereby effectively limiting the movement range of the engine cylinder. Conversely, when the piston rod retracts, the first rotating plate 1620 reverses its rotation, and the second limiting base plate 1650 also resets, thereby releasing the constraint on the movement of the engine cylinder. When the two said second limiting assemblies 1600 are used simultaneously, the movement of the said engine block 5000 on the conveying path of the said conveying mechanism 1400 is limited; through such a design, the second limiting assembly 1600 can flexibly switch states under different working conditions, ensuring the running stability and reliability of the entire system, while avoiding accidental situations caused by misoperation or mechanical failure.

[0091] Further, please refer to Figure 8 Further, a third limiting assembly 1700 is arranged at one end of the driving mechanism through a limiting mounting plate 1750, for preventing other engine blocks 5000 from entering the conveying mechanism 1400 when the engine block 5000 is disassembled and the auxiliary component 4000 is assembled. The third limiting assembly 1700 comprises a third limiting cylinder 1710 and a limiting driving plate 1720 connected by the piston rod of the third limiting cylinder 1710; both ends of the limiting mounting plate 1750 are provided with limiting sleeves 1740, both ends of the limiting driving plate 1720 are provided with limiting guide rods 1730 which can move based on the limiting sleeves 1740, and the top of the limiting guide rod 1730 is provided with a limiting base block 1760, and a limiting stop rod 1770 is further arranged through the limiting base block 1760.

[0092] In use, when the engine block 5000 needs to be disassembled and the auxiliary component 4000 is assembled, the third limiting assembly 1700 starts to work. By controlling the extension and retraction of the piston rod of the third limiting cylinder 1710, the limiting driving plate 1720 moves accordingly, driving the limiting guide rod 1730 to slide in the limiting sleeve 1740. The limiting base block 1760 cooperates with the limiting stop rod 1770 to form an effective blocking structure, ensuring that other engine blocks 5000 cannot enter the working area of the conveying mechanism 1400. This process not only improves the safety of operation, but also avoids damage to the equipment or interruption of production caused by accidental interference. In addition, the position of the limiting stop rod 1770 is accurately designed, which can provide maximum protection and isolation without affecting the disassembly of the current engine block 5000.

[0093] To further optimize the use experience, the device is also equipped with high-precision sensors for real-time monitoring of the position and state of the auxiliary component 4000. This not only avoids operational errors caused by human negligence, but also dynamically adjusts the angle and force of the auxiliary component 4000 during processing, ensuring that the precision and stability of the cylinder processing are always in the best state. In addition, the design of the device fully considers safety, with multiple protection mechanisms such as overload protection and emergency stop function, maximizing the safety of the operator.

[0094] By introducing such a circulating turnover device, not only can the labor intensity be significantly reduced, but also the turnover time of the auxiliary component 4000 can be greatly shortened, thereby improving the overall efficiency of the production line. This innovative solution brings a new solution to the engine cylinder 5000 processing field, and also provides a useful reference for the automation upgrade of related industries.

[0095] Further, please refer to Figure 2 and Figure 3 , the top of the conveying device 3000 is also provided with a protective plate 3300; the reason for setting the protective plate 3300 on the top of the conveying device 3000 is that there are iron filings, dust and other impurities in the environment of the engine cylinder 5000 processing workshop. If these substances fall on the surface or joint surface of the auxiliary component 4000 (such as the accompanying bracket and the simulated cylinder cover), it will seriously affect the assembly precision of the component and the product quality. For example, iron filings may be embedded in the positioning hole or sealing surface of the component, causing gaps or scratches during installation, and dust accumulation may affect the fit of the component and the cylinder, and even bring in aluminum filings and other pollutants during subsequent processing. The protective plate 3300 forms a physical barrier by covering the top of the conveying device 3000, blocking the impurities in the environment from falling directly onto the surface of the auxiliary component 4000, ensuring that the component remains clean during the circulating transfer process, avoiding assembly errors or product damage caused by impurities, and thus ensuring the precision and quality stability of the engine cylinder 5000 processing.
