Description

Technical Field

[0001] This invention belongs to the field of engine manufacturing equipment, and in particular relates to a multi-faceted machining system and machining method for engine cylinder heads. Background Technology

[0002] The engine cylinder head is a core component of a diesel engine, working together with the cylinder block to form the engine's working core. Its structure is a regular cuboid, requiring high-precision machining of its six surfaces and the hole system distributed on each surface. The machining quality directly affects the engine's power performance, sealing performance, and service life, thus requiring extremely high precision and integrity in the machining process.

[0003] Current engine cylinder head processing mostly adopts traditional assembly line operation mode, which requires the configuration of special processing equipment step by step according to the processing process. Each process corresponds to an independent special machine, resulting in high equipment investment costs and large floor space. It relies on a large number of intermediate links such as clamping, transfer, and unloading, which not only requires a large number of operators to cooperate, but also requires a large number of equipment. The huge floor space occupied, and the lack of automation limits production efficiency and makes it difficult to adapt to the needs of large-scale production. Summary of the Invention

[0004] This invention addresses the problems of complex six-sided machining, clamping, and transfer processes and large footprint of current engine cylinder head manufacturing methods by providing a multi-sided machining system for engine cylinder heads.

[0005] To solve the above problems, the technical solution adopted by the present invention is a multi-faceted machining system for engine cylinder heads, including a displacement device and a machining device. The displacement device includes a lateral translation component, the moving end of which is provided with a clamping frame. The clamping frame has a vertical surface and is arranged in the lateral direction. Vertical clamping components are respectively provided on the horizontal opposite sides of the clamping frame, and the clamping part of the vertical clamping component can rotate around a vertical axis. Horizontal clamping components are respectively provided on the vertical opposite sides of the clamping frame, and the clamping part of the horizontal clamping component can rotate around a horizontal axis. The machining device includes at least one machining head, which is disposed on one side of the lateral translation component, and the spindle of the machining head is arranged in the longitudinal direction. It also includes a conveying device, which is located at both ends of the lateral translation component, and the conveying device is used to convey the blank and feed the blank into the displacement device. Stable lateral movement is achieved by driving the clamping frame through the lateral translation component. Combined with the bidirectional rotation function of the vertical clamping component around the vertical axis and the lateral clamping component around the horizontal axis, the blank posture can be flexibly adjusted, enabling multi-face processing to be completed in a single clamping. This completely eliminates the traditional multiple clamping mode, significantly reduces clamping time and positioning errors, and ensures the consistency of positional accuracy of each processed surface. The conveying device and the processing device are located at opposite ends of the lateral translation component, creating a seamless automated process that eliminates the need for manual intervention in blank transfer, reducing reliance on manual labor and the risk of operational errors. At the same time, it reduces the space required for equipment layout, solving the pain point of large floor space in traditional production lines.

[0006] As a preferred implementation of a multi-faceted machining system for engine cylinder heads, the conveying device includes a first roller conveyor support, on which a first longitudinal translation component is mounted. The moving end of the first longitudinal translation component is equipped with a first roller conveyor, the conveying direction of which is longitudinal, and one end of the first roller conveyor can extend into the clamping frame. The first longitudinal translation component can precisely drive the first roller conveyor to extend and retract longitudinally, allowing one end to directly extend into the clamping frame to complete the blank conveying. This achieves direct connection of the blank from the conveying link to the machining station, avoiding problems such as blank collisions and positional shifts that may occur during manual transfer, effectively ensuring initial clamping accuracy. The longitudinal conveying direction is precisely matched to the vertical plane of the clamping frame, resulting in a short and direct feeding path without the need for additional turning or adjustment steps, significantly improving feeding efficiency and laying the foundation for subsequent continuous processing.

[0007] As a preferred implementation of a multi-faceted machining system for engine cylinder heads, the conveying device further includes a second roller support. Along the longitudinal direction, the first roller support and the second roller support are respectively located on both sides of the clamping frame. The second roller support is equipped with a second longitudinal translation component, and the moving end of the second longitudinal translation component is equipped with a second roller. In the longitudinal direction, the first roller and the second roller are arranged opposite each other. The first roller and the second roller are positioned on both sides of the clamping frame and arranged opposite each other, forming a closed-loop automated conveying chain for feeding, processing, and unloading. The entire process from blank feeding to finished product output requires no manual intervention, achieving continuous batch production and significantly improving production cycle time. The opposite design of the two rollers ensures the coaxiality of the blank conveying. During feeding, the blank accurately enters the clamping area, and during unloading, the finished product smoothly leaves the processing station, avoiding surface damage or precision deviation caused by blank displacement or collision during conveying, and ensuring product quality stability.

[0008] As a preferred implementation of a multi-faceted machining system for engine cylinder heads, the first longitudinal translation component and the second longitudinal translation component are rodless cylinders. Compared with traditional cylinders, rodless cylinders have a more compact structure and smaller axial dimensions, effectively adapting to the installation space on both sides of the clamping frame, significantly reducing the overall footprint of the conveying device, and meeting the requirements of integrated equipment design. Their operation is stable, with fast response speed and precise stroke control, accurately driving the roller conveyor to extend and retract to the target position, ensuring the positional accuracy of billet feeding and unloading, and reducing positioning deviations. Simultaneously, rodless cylinders have no exposed piston rods, resulting in good sealing performance, low wear, low maintenance costs, and long service life, effectively improving the operational stability and durability of the entire machining system and reducing long-term operating costs.

[0009] As a preferred implementation of a multi-faceted machining system for engine cylinder heads, a lifting drive cylinder is provided on each of the vertically opposite sides of the clamping frame. The cylinder rod of the lifting drive cylinder is connected to a mounting plate, and a first linear guide rail is provided between the mounting plate and the clamping frame. Two transverse clamping components are respectively arranged on the opposite surfaces of the two mounting plates. The lifting drive cylinder can drive the mounting plate and the transverse clamping components to achieve vertical height adjustment, which can flexibly adapt to engine cylinder head blanks of different heights and sizes, greatly expanding the processing adaptability range of the system and meeting diverse production needs without changing special fixtures. The first linear guide rail between the mounting plate and the clamping frame provides precise guidance for the lifting movement, ensuring the stability and straightness of the transverse clamping components during the lifting process, avoiding blank clamping misalignment caused by component offset, ensuring the coaxiality and stability of blank clamping, and providing a reliable guarantee for subsequent high-precision machining.

[0010] As a preferred implementation of a multi-faceted machining system for engine cylinder heads, the vertical clamping assembly and the horizontal clamping assembly have identical structures, both including a rotary cylinder. A rotating plate is mounted on the rotating part of the rotary cylinder, and a clamping cylinder is mounted on the side of the rotating plate facing away from the rotary cylinder. A clamping plate is mounted on the cylinder rod of the clamping cylinder. First, the clamping cylinder drives the clamping plate to quickly and firmly clamp the workpiece. Then, the rotary cylinder drives the workpiece to precisely rotate and reposition around the corresponding axis. The actions are smoothly connected, significantly improving machining efficiency. The vertical and horizontal clamping assemblies have completely identical structures, facilitating standardized production, assembly, and subsequent maintenance, reducing equipment manufacturing costs and maintenance difficulty. Simultaneously, it ensures the consistency and reliability of clamping and rotation actions in different directions, avoiding deviations in repositioning accuracy due to component differences.

[0011] As a preferred implementation of a multi-faceted machining system for engine cylinder heads, the vertical clamping assembly and the horizontal clamping assembly each include pneumatic pins. Multiple positioning holes are evenly distributed along the circumference of the rotating plate, and the pneumatic pins can be inserted into these positioning holes. When the rotating cylinder drives the workpiece to the target machining angle, the pneumatic pins quickly insert into the corresponding positioning holes to achieve mechanical locking, firmly fixing the rotating plate to the clamping assembly body. This effectively avoids workpiece angle deviation caused by cutting forces, vibrations, and other factors during machining, ensuring the positional accuracy and dimensional consistency of multi-faceted machining. The multiple positioning holes evenly distributed along the circumference of the rotating plate enable precise stopping at multiple angles, significantly improving the system's machining flexibility and applicability, and expanding the equipment's application scenarios.

[0012] As a preferred implementation of a multi-faceted machining system for engine cylinder heads, two machining heads are provided, one on each side of the transverse translation assembly along the longitudinal direction. Each side of the transverse translation assembly has a machining head base, and the machining heads are mounted on the bases via lead screws. A second linear guide rail is also provided between the machining heads and the bases. The symmetrical arrangement of the two machining heads on both sides of the transverse translation assembly allows for simultaneous machining of two opposite surfaces of the workpiece. Compared to single-sided machining, this significantly shortens the machining cycle for a single workpiece, substantially improving production efficiency, and is particularly suitable for large-scale batch production. The lead screw transmission mechanism has high-precision feed adjustment capabilities, and combined with the guiding effect of the second linear guide rail, it enables smooth and precise movement of the machining heads along a set direction, ensuring accurate control of machining dimensions. This allows for flexible adaptation to diverse machining needs such as machining holes of different depths and planar milling with different surface roughness requirements, thereby improving product machining quality.

[0013] On the other hand, the present invention also provides a multi-faceted machining method for an engine cylinder head, comprising the following steps: S1. The billet is conveyed from the first roller conveyor to one end near the clamping frame. The first longitudinal translation component drives the first roller conveyor to translate and feed the billet into the clamping frame. The two transverse clamping components extend to clamp the billet. The first longitudinal translation component drives the first roller conveyor to retract. S2. The lateral translation component drives the clamping frame to move laterally between the two machining heads, and the two machining heads process a set of surfaces of the blank; S3. The horizontal clamping assembly and / or the vertical clamping assembly reposition the blank once or multiple times, and the two processing heads process another set or more sets of surfaces of the blank; S4. The clamping frame moves back to the conveying device, the second longitudinal translation component drives one end of the second roller conveyor to move to the clamping frame, the two transverse clamping components place the processed blank on the second roller conveyor, the second longitudinal translation component retracts, and the second roller conveyor sends out the processed blank.

[0014] Step S3 includes: two lateral clamping components driving the billet to rotate 90° along the horizontal axis; or, two vertical clamping components extending to clamp the billet, the lateral clamping components separating, and then the two vertical clamping components driving the billet to rotate 90° along the vertical axis, and the two lateral clamping components re-clamping the billet.

[0015] The multi-faceted machining method for engine cylinder heads provided by this invention achieves automated and precise blank feeding through the coordinated action of the first roller conveyor and the transverse clamping assembly in step S1, eliminating the need for manual transfer and auxiliary positioning. This reduces labor intensity and operational errors while ensuring clamping stability and feeding efficiency. In step S2, the transverse translation assembly smoothly transfers the blank between the two machining heads, enabling simultaneous machining on both sides, significantly shortening the machining time for a single surface. Furthermore, the balanced force distribution prevents blank deformation, ensuring the flatness and parallelism of the machined surfaces. In step S3, the flexible combination and displacement of the transverse and vertical clamping assemblies allows the blank to be rotated around horizontal and vertical surfaces. Multi-angle rotation of the vertical axis, combined with two precise 90° displacement methods, enables full-coverage processing of six sides and holes without multiple clamping operations, effectively avoiding the accumulation of positioning errors and ensuring consistent positional accuracy of each processed surface. Step S4 achieves automated unloading of finished products through the second roller conveyor, avoiding surface damage and contamination caused by manual contact. It forms a complete closed loop with the feeding and processing steps, building a fully automated processing chain, significantly improving production cycle time and batch production stability, while greatly reducing equipment footprint and manual dependence, effectively solving the pain points of traditional assembly line processing such as cumbersome procedures, low efficiency, and high costs.

[0016] As can be seen from the above technical solutions, the advantages of this invention are as follows: This system drives the clamping frame to move stably through the lateral translation component, and with the bidirectional rotation function of the vertical and lateral clamping components, it can complete multi-face processing of the billet in one clamping, completely abandoning the traditional multiple clamping mode, greatly reducing clamping time and positioning errors, and ensuring the consistency of positional accuracy of each processing surface; The conveying device adopts a design in which the first roller conveyor and the second roller conveyor are placed on both sides of the clamping frame and arranged facing each other, combined with the precise extension and retraction driven by the rodless cylinder, forming a closed-loop automated link for loading, processing, and unloading. The billet does not need to be manually transferred throughout the process, which avoids bumps and positional deviations, and significantly improves the production cycle. At the same time, the rodless cylinder has a compact structure, runs smoothly, and has low maintenance costs, further optimizing the equipment layout and operational stability; The lifting drive cylinder on the clamping frame, in conjunction with the first linear guide rail, can drive the lateral clamping component to flexibly adjust the height to adapt to billets of different sizes and specifications, broaden the processing adaptability range, and ensure the coaxiality and stability of the clamping; The vertical and The lateral clamping assembly adopts a structure of "rotary cylinder and clamping cylinder", combined with a precise locking design of pneumatic pins and positioning holes, to achieve continuous action of billet clamping, rotation and positioning. This ensures both displacement accuracy and processing stability, while facilitating standardized production and maintenance. The multi-angle stop function also enhances system flexibility. The dual-sided processing heads, combined with high-precision transmission via lead screws and a second linear guide, can simultaneously process opposite surfaces of the billet, shortening the processing cycle, adapting to diverse processing needs, and improving product quality. The corresponding processing method, through the coordinated operation of steps S1 to S4, achieves automated and precise billet feeding, stable transfer processing, flexible displacement processing, and automated finished product unloading, constructing a fully automated process. This not only reduces reliance on manual labor and labor intensity, avoiding human error and finished product damage, but also significantly reduces the equipment footprint. It effectively solves the pain points of traditional assembly lines—cumbersome processes, low efficiency, and high costs—and adapts to the needs of large-scale batch production, combining high precision, high efficiency, high stability and high applicability.

[0022] To make the objectives, features, and advantages of this patent more apparent and understandable, the technical solutions of this patent will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this patent, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0023] like Figure 1 , 2 As shown, the present invention discloses a multi-faceted machining system for engine cylinder heads, the core of which includes a displacement device 01, a machining device 02 and a conveying device 03. The three components achieve automated and high-precision multi-faceted machining of engine cylinder head blanks through precise structural layout and transmission coordination.

[0024] The displacement device 01, as the core component for billet clamping and displacement, has a lateral translation component 1 fixedly mounted on its bottom by bolts. This lateral translation component 1 is preferably a ball screw slide, with its moving end's mounting surface welded to the back of the clamping frame 2 to ensure connection strength and motion synchronization. The clamping frame 2 has a rectangular frame structure, with a vertical surface and horizontal orientation. Vertical clamping components 3 are symmetrically fixed to the inner sides of the top and bottom horizontal sides of the frame by bolts. The clamping parts of the vertical clamping components 3 can rotate around their own vertical axis. Lateral clamping components 4 are symmetrically mounted to the inner sides of the left and right vertical sides of the frame by bolts. The clamping parts of the lateral clamping components 4 can rotate around their own horizontal axis. Through the coordinated action of the vertical and lateral clamping components, the attitude adjustment of the billet in three-dimensional space is achieved.

[0025] The processing device 02 includes two identical processing heads 5, symmetrically arranged on both sides of the transverse translation component 1 along the longitudinal direction. The spindle of the processing head 5 is set horizontally along the longitudinal direction, and the end of the spindle can be adapted to install various processing tools such as milling cutters and drills to meet different processing needs such as planar milling and hole processing. The head base 21 is fixed to the ground on both sides of the transverse translation component 1 by expansion bolts. The bottom of the processing head 5 is connected to the head base 21 by a lead screw 22. A second linear guide 23 is also assembled between the processing head 5 and the head base 21. The guide seat of the second linear guide 23 is bolted to the head base 21, and the slider is bolted to the bottom of the processing head 5. Through the rotation drive of the lead screw 22 and the guiding limit of the second linear guide 23, the processing head 5 can achieve high-precision feed motion along the longitudinal direction.

[0026] The conveying device 03 and processing device 02 are located at opposite ends of the transverse translation component 1, respectively, for automatic loading of billets and automatic unloading of finished products. It includes a first roller conveyor support 6 and a second roller conveyor support 9, both longitudinally positioned on opposite sides of the clamping frame 2 and fixed to the ground with expansion bolts. A first longitudinal translation component 7 is bolted to the top of the first roller conveyor support 6. The moving end of the first longitudinal translation component 7 is bolted to the bottom support of the first roller conveyor 8. The first roller conveyor 8 has a longitudinal conveying direction, and its roller shaft is rotatably connected to the support via a bearing seat. The end of the first roller conveyor 8 near the clamping frame 2 can extend into the clamping frame 2 under the drive of the first longitudinal translation component 7. Similarly, a second longitudinal translation component 10 is bolted to the top of the second roller conveyor support 9. Its moving end is bolted to the bottom support of the second roller conveyor 11. The structure of the second roller conveyor 11 is identical to that of the first roller conveyor 8, and it is positioned directly opposite the first roller conveyor 8 in the longitudinal direction to ensure coaxiality of the billet conveying. It is worth noting that both the first longitudinal translation component 7 and the second longitudinal translation component 10 use rodless cylinders. The cylinder body of the rodless cylinder is bolted to the corresponding roller support, and the slider is bolted to the bottom support of the roller. With its compact structural design, it effectively saves installation space.

[0027] The inner sides of the left and right vertically opposite sides of the clamping frame 2 are also fixed with lifting drive cylinders 12 by bolts. The cylinder rod of the lifting drive cylinder 12 is set upward in the vertical direction, and the top of the cylinder rod is connected to the mounting plate 13 by thread. The mounting plate 13 has a rectangular flat plate structure, and a first linear guide rail 14 is also assembled between its back and the clamping frame 2. The guide rail seat of the first linear guide rail 14 is fixed to the clamping frame 2 by bolts, and the slider is bolted to the back of the mounting plate 13. The two transverse clamping components 4 are respectively fixed to the opposite surfaces of the two mounting plates 13 by bolts. Through the extension and retraction drive of the lifting drive cylinder 12 and the guiding action of the first linear guide rail 14, the height of the transverse clamping components 4 in the vertical direction can be adjusted.

[0028] like Figure 3 As shown, the vertical clamping assembly 3 and the horizontal clamping assembly 4 have identical structures, both including a rotary cylinder 15, a rotary plate 16, a clamping cylinder 17, a clamping plate 18, a pneumatic pin 19, and a positioning hole 20. The cylinder body of the rotary cylinder 15 is fixed to the corresponding side bolt of the clamping frame 2 via a flange. The rotating part of the rotary cylinder 15 is connected to the center hole of the rotary plate 16 via a flat key, and the two are locked together by a set screw. The rotary plate 16 has a circular flat plate structure, and the clamping cylinder 17 is fixed to its side facing away from the rotary cylinder 15 by bolts. The cylinder rod of the clamping cylinder 17 is arranged radially, and the end of the cylinder rod is connected to the clamping plate 18 by a thread. The clamping surface of the clamping plate 18 is covered with an anti-slip rubber pad to enhance clamping stability and avoid damage to the surface of the blank. The outer side of the cylinder body of the rotary cylinder 15 is also fixed with a pneumatic pin 19 by a bracket bolt. The piston rod of the pneumatic pin 19 is arranged radially along the rotating plate 16. Multiple positioning holes 20 are evenly opened on the rotating plate 16 along the circumference. The diameter of the positioning hole 20 is adapted to the diameter of the piston rod of the pneumatic pin 19. When the rotating plate 16 rotates to the target angle, the piston rod of the pneumatic pin 19 can extend and be inserted into the positioning hole 20 to achieve precise locking of the rotating plate 16.

[0029] In this embodiment, all components are connected by detachable bolt or threaded connections, facilitating future maintenance and component replacement. All transmission joints are lubricated with grease to reduce motion resistance and component wear, extending equipment lifespan. Through this structural design, the system can achieve fully automated operation of the entire process from blank loading, clamping, positioning, processing to unloading, significantly improving processing efficiency and accuracy.

[0030] Example 2 This embodiment further provides a multi-faceted machining method for an engine cylinder head, including the following steps: S1. The billet is conveyed from the first roller conveyor 8 to one end near the clamping frame 2. The first longitudinal translation component 7 drives the first roller conveyor 8 to translate and feed the billet into the clamping frame 2. The two transverse clamping components 4 extend to clamp the billet. The first longitudinal translation component 7 drives the first roller conveyor 8 to retract. S2. The lateral translation component 1 drives the clamping frame 2 to move laterally between the two processing heads 5, and the two processing heads 5 process a set of surfaces of the blank; S3. The lateral clamping assembly 4 and / or the vertical clamping assembly 3 reposition the billet once or multiple times, and the two machining heads process another set or more sets of surfaces of the billet, including: Two transverse clamping components 4 drive the billet to rotate 90° along the horizontal axis; Alternatively, the two vertical clamping components 3 extend to clamp the billet, the horizontal clamping component 4 separates, and then the two vertical clamping components 3 drive the billet to rotate 90° along the vertical axis, and the two horizontal clamping components 4 re-clamp the billet; S4. The clamping frame 2 moves back to the conveying device 03. The second longitudinal translation component 10 drives one end of the second roller conveyor 11 to move into the clamping frame 2. The two transverse clamping components 4 place the processed blank on the second roller conveyor 11. The second longitudinal translation component 10 retracts and the second roller conveyor 11 sends out the processed blank.

[0031] The following is a processing example: Loading and Positioning: The engine cylinder head blank to be processed is placed at the feed end of the first roller conveyor 8. The drive motor of the first roller conveyor 8 is started, and the blank is conveyed longitudinally to a designated position near the clamping frame 2. Then, the first roller conveyor 8 stops operating. At this time, the first longitudinal translation component 7 is activated, driving the first roller conveyor 8 to move towards the clamping frame 2 until the blank is completely inside the clamping area of ​​the clamping frame 2, and the center of the blank is aligned with the center of the clamping frame 2. Subsequently, the clamping cylinders 17 of the two transverse clamping components 4 extend synchronously, driving the clamping plate 18 to move closer to the blank until the anti-slip rubber pad is tightly attached to the left and right sides of the blank, achieving a firm clamping of the blank. After clamping is completed, the first longitudinal translation component 7 drives the first roller conveyor 8 to return to the initial position in the opposite direction to avoid interfering with subsequent processing actions.

[0032] Initial machining: The transverse translation component 1 is activated, driving the clamping frame 2 and the clamped blank to move smoothly laterally until the blank is positioned between the two machining heads 5, with the front and rear surfaces of the blank aligned with the spindle axes of the two machining heads 5. According to machining requirements, milling cutters and drill bits are installed on the two machining heads 5 respectively. The machining heads 5 are activated, and through the cooperation of the lead screw 22 and the second linear guide 23, the machining heads 5 are driven to feed longitudinally, simultaneously performing planar milling and hole drilling on the front and rear surfaces of the blank. After machining is completed, the machining heads 5 return to their initial position.

[0033] Multiple repositioning processes: First repositioning: Maintaining the clamping state of the billet by the transverse clamping assembly 4, its rotary cylinder 15 is activated, driving the billet to rotate 90° clockwise around the horizontal axis. After rotation to the correct position, the pneumatic pin 19 extends and inserts into the positioning hole 20 of the rotating plate 16 to lock it in place. At this time, the upper and lower surfaces of the billet turn towards the machining head 5. The machining head 5 is activated, and after changing the corresponding tool, the upper and lower surfaces are milled, and the remaining holes are drilled and tapped. After machining is completed, the machining head 5 retracts.

[0034] Second repositioning: The clamping cylinder 17 of the transverse clamping assembly 4 retracts, releasing the blank and separating it to both sides; subsequently, the clamping cylinders 17 of the two vertical clamping assemblies 3 extend, causing the clamping plate 18 to fit tightly against the upper and lower surfaces of the blank, achieving secondary clamping of the blank. The rotating cylinder 15 of the vertical clamping assembly 3 is activated, causing the blank to rotate 90° counterclockwise around the vertical axis, and the pneumatic pin 19 is inserted into the positioning hole 20 to lock and position; then, the clamping cylinder 17 of the transverse clamping assembly 4 extends again, re-clamping the blank, and the vertical clamping assembly 3 releases the clamp and resets. At this time, the remaining two sides of the blank turn towards the machining head 5. After the machining head 5 changes the tool, it completes the milling of these two sets of surfaces and the machining of the hole system, ensuring that all six surfaces and all holes are machined in place.

[0035] Material unloading: After all processing steps are completed, the transverse translation component 1 drives the clamping frame 2 back to the initial position corresponding to the conveying device 03. The second longitudinal translation component 10 is activated, driving the second roller conveyor 11 to translate towards the clamping frame 2 until its end extends into the clamping frame 2 and is aligned with the bottom of the blank; the clamping cylinders 17 of the two transverse clamping components 4 retract, placing the finished cylinder head smoothly on the second roller conveyor 11; then the second longitudinal translation component 10 drives the second roller conveyor 11 back to the initial position, and starts the drive motor of the second roller conveyor 11 to transport the finished cylinder head to the unloading end, completing the entire processing flow.

[0036] As can be seen from the above embodiments, the beneficial effects of the present invention are as follows: First, by utilizing the bidirectional rotary clamping component and lateral translation function of the displacement device, the entire process of machining six sides and the hole system can be completed in one clamping of the billet, completely eliminating the traditional multiple clamping mode, greatly reducing the accumulation of positioning errors, and controlling the flatness of each surface and the positional error of the hole system within a high-precision range, ensuring consistent product quality; Second, the conveying device adopts a double roller conveyor layout and rodless cylinder drive to construct a closed-loop automated link for feeding, processing, and unloading, eliminating the need for manual transfer of the billet throughout the process, avoiding collision damage and positional deviation, significantly improving the production cycle, and shortening the processing cycle compared to traditional assembly lines; Third, the modular structure and lifting adjustment design of the clamping component... The multi-angle stop function not only adapts to cylinder head blanks of different sizes and specifications, expanding the processing range, but also facilitates standardized production and subsequent maintenance, reducing equipment manufacturing costs and maintenance difficulty; fourth, the dual-sided processing head, combined with high-precision lead screws and linear guide transmission, can simultaneously complete relative surface processing, greatly improving production efficiency, and can flexibly adapt to diverse processing needs such as milling, drilling, and tapping; fifth, the overall structure is compact and reasonable, and the design of rodless cylinders and integrated frames effectively reduces the equipment's footprint. The fully automated operation reduces manual dependence and labor intensity, while reducing component wear and operational failures, improving equipment durability and long-term operational stability, significantly reducing overall production costs, and perfectly adapting to the needs of large-scale mass production.
