Abstract
Description
Technical Field
[0001] This invention relates to an assembly conveyor line, and more particularly to an assembly conveyor line and method for cylinder head and cylinder block. Background Technology
[0002] As core components of an engine, the precise assembly of the cylinder block and cylinder head is a crucial step in the engine assembly process. The assembly accuracy of the cylinder head and cylinder block directly determines the engine's sealing performance, power output, and overall operational stability. Only by completing the reliable assembly of the two can the subsequent normal assembly and use of the engine be guaranteed. Therefore, the assembly of the cylinder block and cylinder head is an indispensable and important part of engine manufacturing.
[0003] In the existing technology, the assembly of cylinder block and cylinder head is mostly completed manually. In the specific operation, the operator first moves the cylinder block to the designated assembly station using a handling tool. The cylinder block is initially fixed with simple tooling such as shims and clamps. Then, the cylinder head is manually moved to the top of the cylinder block. With the cooperation of multiple people, the position and angle of the cylinder head are adjusted so that the assembly interface of the cylinder head and the cylinder block are aligned. Then, the cylinder head is slowly lowered to complete the assembly. After the assembly is completed, the assembled cylinder block and cylinder head assembly is manually moved to the next process. In the whole process, if it is necessary to change to a different specification of cylinder block for assembly, the operator needs to manually disassemble, replace and adjust the tooling and clamps. When maintaining and replacing the tooling, it is also necessary to use tools to gradually disassemble the connecting parts, and then reassemble them one by one after maintenance. The existing manual assembly method has many obvious drawbacks. Manually handling cylinder blocks and cylinder heads is not only labor-intensive but also prone to damage due to improper human control, affecting product quality. Manually adjusting the alignment and angle of the cylinder head and cylinder block is difficult to achieve precisely, easily leading to misalignment of the assembly interface, reducing assembly accuracy, and consequently affecting engine performance. The simple method of manually fixing the cylinder block allows for easy shaking and displacement during assembly, further reducing accuracy and failing to achieve stable positioning. The connection between assembly processes relies on manual handling, preventing continuous assembly and transfer operations and resulting in low production efficiency. Adjusting tooling for different cylinder block specifications is cumbersome, time-consuming, and lacks adaptability. The disassembly and installation of tooling fixtures are complex, lacking a quick-disassembly / reassembly design, resulting in insufficient flexibility for maintenance and replacement, consuming significant time, and impacting the overall production rhythm. Furthermore, the inconsistent nature of manual assembly operations is easily affected by operator skill and work status, leading to inconsistent assembly quality and making it difficult to guarantee standardized product production.
[0004] Therefore, those skilled in the art are dedicated to providing an assembly transmission line and method for cylinder heads and cylinder blocks that can effectively solve the above-mentioned technical problems. Summary of the Invention

[0010] Furthermore, a positioning seat is provided on the transmission frame, a positioning guide is provided on the inner side of the positioning seat, and a sliding guide is provided on the outer side of the upright plate.

[0011] Furthermore, it also includes blocking and limiting components; The blocking and limiting component includes a limiting cylinder disposed on the outside of the positioning seat. The output end of the limiting cylinder passes through the positioning seat and is provided with a telescopic seat. The telescopic seat is slidably located inside the positioning box. The positioning box is connected to the inner side of the positioning seat. The upper and lower ends of the positioning box are respectively flush with the upper and lower ends of the positioning guide. Both the upper and lower ends of the telescopic seat are provided with racks. Two swing seats are rotatably disposed inside the positioning box. Each swing seat is located above and below the telescopic seat and meshes with each rack. Each swing seat is provided with a limiting swing rod. Each limiting swing rod can extend through the swing windows opened at the upper and lower ends of the positioning box to limit the sliding guide by swinging outwards from the positioning box.
[0012] Furthermore, the gripping robot includes a robotic arm on which a cylinder head gripping assembly is mounted; The cylinder head gripping assembly includes a connector connected to the robotic arm. The connector is located at the front end of the guide seat, and a guide rail is located at the rear end of the guide seat. Two adjusting seats are slidably mounted on the guide rail. An adjusting cylinder is connected to the guide seat between each adjusting seat. The adjusting cylinder is simultaneously connected to each adjusting seat and is used to adjust the distance between the two adjusting seats to achieve gripping. Each adjusting seat is equipped with a gripping arm.
[0013] Furthermore, it also includes a cylinder head transfer unit for transferring the cylinder head to the working position of the gripping robot, which is located between the cylinder head transfer unit and the cylinder block conveyor line.
[0014] A method for assembling and transferring a cylinder head and a cylinder block includes the following steps: First, place the cylinder head on the working side of the gripping robot or on the cylinder head transmission unit. The cylinder head transmission unit will then transport it to the working range of the gripping robot. At the same time, place the cylinder body on the cylinder body loading assembly at the input section of the cylinder body conveyor line. The operator can rotate the adjustment disc to drive the adjustment rod to rotate, which in turn drives the adjustment disc to rotate. This allows for the adjustment of the cylinder body fixing rod angle to accommodate different cylinder body specifications. After adjustment, tighten the locking screw to engage the second anti-slip edge of the locking head with the first anti-slip edge of the adjustment rod to achieve locking and ensure stable cylinder body positioning. Then, the transmission motor is started to drive the transmission roller to rotate, which in turn drives the transmission steel belt to move along the transmission frame. The cylinder loading assembly moves with the transmission steel belt from the input section to the assembly section. During the transmission process, the guide rib on the inner side of the transmission steel belt slides in conjunction with the guide groove of the support plate to provide guidance and limit for the transmission. The support plate also provides support for the transmission steel belt in the assembly section. When the cylinder loading assembly carrying the cylinder moves to the positioning seat in the assembly section, the sliding guide part on the outer side of the upright plate of the cylinder loading assembly cooperates with the positioning guide part on the inner side of the positioning seat to achieve initial positioning of the cylinder. Then, the blocking and limiting component is activated, and the limiting cylinder drives the telescopic seat to slide in the positioning box. The racks at the upper and lower ends of the telescopic seat drive the swing seat to rotate, so that the limiting swing rod extends outward through the swing window and fits against the sliding guide part to achieve hard limiting of the cylinder loading assembly. At the same time, the transmission motor stops working, and the transmission steel belt stops, ensuring that the cylinder does not move during assembly. Then, the gripping robot begins to operate. The robotic arm moves the cylinder head gripping assembly to the cylinder head placement position. An adjusting cylinder drives two adjusting seats to move closer together along the guide rail, causing the gripping arm to close and grasp the cylinder head. After grasping, the robotic arm moves the cylinder head gripping assembly to directly above the cylinder block in the assembly section. After precise adjustment of the position and angle, the cylinder head is lowered, aligning the cylinder head with the cylinder block assembly interface and completing the assembly. During assembly, the cylinder block fixing rod performs secondary positioning of the cylinder block to prevent wobbling and improve assembly accuracy. After the cylinder head and cylinder block are assembled, the blocking limit component resets, and the limit cylinder drives the telescopic seat to slide in the opposite direction, causing the rack and pinion belt... The movable swing seat rotates in the opposite direction, and the limit swing rod retracts into the positioning box, releasing the limit on the cylinder block loading assembly. Then, the transmission motor restarts, and the transmission belt continues to move the cylinder block loading assembly from the assembly section to the output section. Upon reaching the unloading position, the operator removes the assembled cylinder head and cylinder block assembly from the cylinder block loading assembly, completing the unloading. The empty cylinder block loading assembly then continues its cyclical movement with the transmission belt, returning to the input section to await the next loading, thus achieving continuous assembly and transmission operations. If it is necessary to remove the cylinder block loading assembly, follow these steps: The operator holds the handle and lifts the cylinder loading assembly upwards. The first and second arc-shaped opening and closing sections of the opening and closing mechanism rotate outwards around the positioning axis under tension, opening the locking area. The limiting part of the positioning head disengages from the locking inlet and outlet, thus completing the disassembly. After maintenance and replacement, the limiting part is placed into the locking area from the locking inlet and outlet. The first and second arc-shaped opening and closing sections return to their original positions and close under the elastic force of the first and second locking return springs. At the same time, the lateral limiting protrusion is engaged in the limiting groove of the limiting part, realizing the quick installation and positioning of the cylinder loading assembly. The positioning head and the transmission steel belt are detachably connected by screws, and the positioning head can be replaced separately as needed.
[0015] The present invention has the following beneficial effects: 1. This invention sets up a cylinder block conveyor line and a cylinder head transmission unit to realize the automated conveying of cylinder blocks and cylinder heads. The cylinder head is automatically picked up, assembled and placed by a gripping robot. The entire process does not require manual handling of heavy cylinder block and cylinder head components, which greatly reduces the labor intensity of operators. At the same time, the stability of mechanical operation avoids component collision damage caused by improper human control.
[0016] 2. The robotic arm of the gripping robot can precisely adjust the position and angle of the cylinder head. Combined with the stable gripping of the cylinder head gripping component, it can accurately align the cylinder head and cylinder block assembly interface. The entire process from gripping to assembly is mechanically positioned, which completely solves the precision defects of manual adjustment and avoids misalignment of the assembly interface. The assembly section is equipped with a positioning seat. The sliding guide of the cylinder block loading component cooperates with the positioning guide of the positioning seat to achieve the initial positioning of the cylinder block. The subsequent blocking and limiting components achieve hard limiting to ensure that the cylinder block does not move during assembly. 3. The cylinder body is placed on the positioning plate of the cylinder body bearing seat. The base and upright plate on the positioning plate, together with the cylinder body fixing rod on the adjustment plate, can adjust the angle of the fixing rod according to the cylinder body specifications and lock it with the locking screw to achieve precise fixation of the cylinder body. During the assembly process, the cylinder body fixing rod performs secondary positioning of the cylinder body, effectively preventing the cylinder body from shaking during assembly, ensuring assembly accuracy from the structure, and solving the instability problem of traditional simple tooling fixation.
[0017] 4. The conveyor belt of the cylinder conveyor line is set around the conveyor roller in one circle. Several cylinder loading components are arranged in a cycle along the conveyor belt. The conveyor belt is divided into an input section, an assembly section and an output section. The cylinders are loaded from the input section, assembled in the assembly section and unloaded from the output section. The empty cylinder loading components return to the input section with the conveyor belt, realizing continuous assembly and transmission; replacing the traditional manual handling and improving the overall production efficiency.
[0018] 5. The adjustment plate of the cylinder block loading assembly can be rotated by the adjustment rod. The fixing seat on the adjustment plate has multiple fixing rod positioning holes. The cylinder block fixing rod can be detachably inserted. The operator can rotate the adjustment plate to drive the adjustment rod to rotate, thereby adjusting the angle of the cylinder block fixing rod to adapt to different specifications of cylinder blocks. After the adjustment is completed, tighten the locking screw so that the second anti-slip edge of the locking head engages with the first anti-slip edge of the adjustment rod to achieve locking. The entire adjustment process does not require disassembling a large number of tooling parts. The operation is simple and quick, which solves the cumbersome problem of traditional tooling adjustment that requires manual disassembly, replacement and debugging, and greatly saves adjustment time.
[0019] 6. The cylinder loading assembly and the transmission steel belt are quickly disassembled and assembled via an opening and closing mechanism. The operator holds the handle and lifts the cylinder loading assembly upwards. The first and second arc-shaped opening and closing sections of the mechanism are pulled and rotate around the positioning shaft, opening the locking area to complete disassembly. After maintenance, the limiting part is placed into the locking area, and it will be reset and closed under the elastic force of the locking return spring. At the same time, the lateral limiting protrusion and the limiting groove cooperate to achieve positioning. No tools are needed to disassemble the connecting parts, achieving quick disassembly and assembly. The positioning head and the transmission steel belt are detachably connected by screws. The positioning head can be replaced separately as needed without replacing the entire cylinder loading assembly or other tooling parts, improving the flexibility of tooling maintenance. 7. From cylinder block positioning and conveying to cylinder head gripping and assembly, and then to finished product unloading, the operating parameters and positioning accuracy of all processes are guaranteed by the equipment, and are not affected by the operator's skill level or working condition. This realizes standardized production of cylinder head and cylinder block assembly, effectively ensures the consistency of product quality, and solves the problem of inconsistent quality in manual assembly.

[0061] In specific applications, an industrial camera, ring light, vision image processing system, and sensing and recognition module (position sensor, proximity switch) can be set up. These components are all existing mature technologies in the field of industrial automation, with no structural innovation, and will not be elaborated here, only integrated and adapted. The vision module is installed at the cylinder head gripping component of the gripping robot, which takes pictures of the cylinder block / cylinder head assembly interface and calculates the positional deviation, driving the robot to make fine adjustments to achieve precise alignment. The sensing module is installed at the positioning seat of the assembly section and the end of the cylinder head transmission unit to realize automatic detection of the cylinder block and cylinder head in place, and trigger the transmission to stop, the robot to operate, etc., improving the assembly accuracy and automation linkage, without changing the original core structure and operation process of the equipment.
[0062] The disassembly base of the opening and closing mechanism of this invention has weight-reduction holes, which reduces the overall weight of the cylinder loading assembly while ensuring structural strength, reduces the motion load on the transmission steel belt, reduces equipment operating energy consumption, and improves the service life of the transmission steel belt. A reinforcing member is installed at the angle between the upright plate and the base to effectively improve the structural strength of the upright plate and prevent deformation of the upright plate due to stress during assembly. A guide rib is provided on the inner side of the transmission steel belt, and a guide groove is opened on the support plate of the assembly section. The two work together to provide guidance and limit for the transmission steel belt, while the support plate provides support for the transmission steel belt in the assembly section, preventing the transmission steel belt from sinking due to bearing the cylinder and ensuring the stability of transmission and assembly. A rubber sleeve is fitted on the outside of the locking screw, which not only improves the operator's grip comfort when tightening but also prevents wear on the screw surface and extends the service life of the components.
[0063] A method for assembling and transferring a cylinder head and a cylinder block includes the following steps: First, place the cylinder head on the working side of the gripping robot 2 or on the cylinder head transmission unit. The cylinder head transmission unit will then transport it to the working range of the gripping robot 2. At the same time, place the cylinder body on the cylinder body loading assembly 7 of the cylinder body conveying line 1 input section 11. The operator can rotate the adjustment disc to drive the adjustment rod 68 to rotate, which in turn drives the adjustment disc 62 to rotate. Adjust the cylinder body fixing rod angle to adapt to different cylinder body specifications. After adjustment, tighten the locking screw 71 so that the second anti-slip edge 76 of the locking head 73 engages with the first anti-slip edge 69 of the adjustment rod 68 to lock and ensure stable cylinder body positioning. Then, the transmission motor 8 is started to drive the transmission roller 5 to rotate, which in turn drives the transmission steel belt 6 to move along the transmission frame 3. The cylinder loading assembly 7 moves with the transmission steel belt 6 from the input section 11 to the assembly section 12. During the transmission process, the guide rib 17 on the inner side of the transmission steel belt 6 slides in cooperation with the guide groove 16 of the support plate 15 to provide guidance and limit for the transmission. The support plate 15 also provides support for the transmission steel belt 6 in the assembly section 12. When the cylinder loading assembly 7 carrying the cylinder moves to the positioning seat 77 in the assembly section 12, the sliding guide part on the outer side of the upright plate 61 in the cylinder loading assembly 7... 79 cooperates with the positioning guide 78 inside the positioning seat 77 to achieve initial positioning of the cylinder. Then, the blocking limit component 81 is activated, and the limiting cylinder 82 drives the telescopic seat 83 to slide inside the positioning box 85. The racks 86 at the upper and lower ends of the telescopic seat 83 drive the swing seat 87 to rotate, so that the limiting swing rod 88 extends outward through the swing window 89 and fits against the sliding guide 79, achieving a hard limit on the cylinder loading component 7. At the same time, the transmission motor 8 stops working, and the transmission steel belt 6 stops, ensuring that the cylinder has no displacement during assembly. Then, the gripping robot 2 begins to work. The robotic arm 90 moves the cylinder head gripping assembly 91 to the cylinder head placement position. The adjusting cylinder 97 drives the two adjusting seats 96 to move closer together along the guide rail 95, causing the gripping arm 98 to close and grip the cylinder head. After gripping, the robotic arm 90 moves the cylinder head gripping assembly 91 to directly above the cylinder block in the assembly section 12. After precisely adjusting the position and angle, the cylinder head is lowered, aligning the cylinder head with the cylinder block assembly interface and completing the assembly. During the assembly process, the cylinder block fixing rod performs secondary positioning of the cylinder block to prevent shaking and improve assembly accuracy. After the cylinder head and cylinder block are assembled, the blocking limit component 81 resets, and the limit cylinder 82 drives the telescopic seat 83 to slide in the opposite direction. 86 drives the swing seat 87 to rotate in the opposite direction, and the limiting swing rod 88 retracts into the positioning box 85, releasing the limit on the cylinder loading assembly 7. Then the transmission motor 8 restarts, and the transmission steel belt 6 continues to move the cylinder loading assembly 7 from the assembly section 12 to the output section 13. After reaching the unloading position, the operator removes the assembled cylinder head and cylinder block assembly from the cylinder loading assembly 7, completing the unloading. The empty cylinder loading assembly 7 continues to circulate with the transmission steel belt 6, returning to the input section 11 to wait for the next loading, realizing continuous assembly and transmission operations. If it is necessary to remove the cylinder loading assembly 7, follow these steps: The operator holds handle 58 and lifts the cylinder loading assembly 7 upwards. The first arc-shaped opening and closing section 31 and the second arc-shaped opening and closing section 32 of the opening and closing mechanism 22 are pulled and rotate outwards around the positioning shaft 39. The locking area 53 opens, and the limiting part 20 of the positioning head 18 disengages from the locking inlet and outlet 55, thus completing the disassembly. After maintenance and replacement, the limiting part 20 is placed into the locking area 53 from the locking inlet and outlet 55. The first arc-shaped opening and closing section 31 and the second arc-shaped opening and closing section 32 are reset and closed under the elastic force of the first locking return spring 36 and the second locking return spring 52. At the same time, the transverse limiting protrusion 56 is inserted into the limiting groove 57 of the limiting part 20, realizing the quick installation and positioning of the cylinder loading assembly 7. The positioning head 18 and the transmission steel belt 6 are detachably connected by screws, and the positioning head 18 can be replaced separately as needed. To enhance maintenance flexibility, the transmission box 9 provides an installation foundation and protection for components such as the transmission frame 3 and the transmission motor 8. Operators can inspect and maintain the internal components by opening the box door 10. The weight reduction holes 28 on the disassembly base 23 of the cylinder loading assembly 7 reduce the overall weight while ensuring structural strength, thereby reducing the moving load on the transmission steel belt 6. The positioning threaded cylinder 29 ensures the firmness of the connection between the disassembly base 23 and the cylinder bearing seat 21. The reinforcing member 66 at the angle between the upright plate 61 and the base 60 enhances the structural strength of the upright plate 61, preventing deformation due to stress during assembly and ensuring the stable operation of the entire assembly transmission line.
