Description

Technical Field

[0001] This utility model relates to the field of engine cylinder head assembly technology, and in particular to an auxiliary tooling for engine cylinder head assembly. Background Technology

[0002] In the field of engine cylinder head assembly, with the rapid development of the automotive industry and related sectors, the requirements for efficiency and quality in engine cylinder head assembly are increasing. Traditional engine cylinder head assembly relies heavily on manual operation and some simple auxiliary tools, which are gradually becoming inadequate when facing large-scale production and high-precision requirements. In the layout of production workshops, this often requires significant manpower and time costs, and it is difficult to guarantee the consistency and accuracy of the operation process, which restricts the improvement of overall engine production capacity and quality stability.

[0003] Traditional engine cylinder head assembly auxiliary tooling often employs hydraulically or pneumatically driven mechanical structures. For example, the extension and retraction of hydraulic cylinders are used to achieve the lifting or moving of certain components. The technical principle is based on the pressure transmission characteristics of liquids or gases; within a sealed container, changing the pressure drives a piston, which in turn moves the connected mechanical components accordingly. While these traditional structures can accomplish basic assembly auxiliary tasks to a certain extent, they have limitations in adaptability and precision in the complex engine cylinder head assembly process.

[0004] In traditional engine cylinder head assembly, the lack of lifting and positioning mechanisms makes it difficult to adjust the cylinder head to the appropriate height and position during the assembly of the cylinder head with other components. This results in excessively long transition times between material handling and assembly actions. For example, when assembling the cylinder head with components such as the valve mechanism, the inability to easily lift the cylinder head to match different assembly height requirements forces workers to spend a significant amount of time manually adjusting and aligning it. This not only increases the time cost of material handling but also easily introduces assembly errors due to the instability of human operation, reducing the assembly quality and production efficiency of the engine cylinder head. This makes it difficult to meet the urgent needs of modern engine production for efficient and high-precision assembly. Therefore, an auxiliary tooling for engine cylinder head assembly is proposed to solve the above problems. Utility Model Content

[0020] As a further description of the above technical solution:

[0021] The slider sidewall is slidably connected to a limiting block, and both sides of the limiting block are fixedly connected to the sidewall of the placement plate.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 - Figure 3This utility model provides an embodiment of an auxiliary tooling for assembling an engine cylinder head, comprising a support column 1. The support column 1 is made of high-strength alloy steel and formed by precision forging, possessing bending and compressive strength. Its outer wall is finely ground, resulting in low surface roughness, providing a good foundation for subsequent sliding connections. A mounting bracket 2 is slidably connected to the outer wall of the support column 1. The main body of the mounting bracket 2 is made of aluminum alloy through extrusion forming, possessing the characteristics of light weight and high strength. Its internal structure is rationally designed, and a box 3 is fixedly connected inside the mounting bracket 2. The box 3 is made of stainless steel sheet bent and welded, and its internal space layout is optimized, enabling... To meet various requirements during engine cylinder head assembly, a connecting plate 16 is fixedly connected to the bottom of the housing 3. The connecting plate 16 is milled from a single piece of carbon steel plate, resulting in high flatness. A motor 5 is fixedly connected to the bottom of the connecting plate 16. The internal windings of the motor 5 are made of high-purity copper. A shaft head 6 is fixedly connected to the output end of the motor 5. The shaft head 6 is made of tempered alloy steel, possessing good toughness and strength. One end is fixedly connected to the side wall of the worm shaft 8. A fixing bracket 7 is fixedly connected to the outer wall of the connecting plate 16. The fixing bracket 7 is welded from multiple stainless steel angle bars, resulting in a stable structure. The worm shaft 8 is rotatably connected inside the fixing bracket 7. The worm shaft 8 is connected to the fixing bracket 7 via these bearings. The frame 7 achieves a rotatable connection. A worm 9 is fixedly connected to the outer wall of the worm shaft 8 via a heat-fitting process. The worm 9 is made of alloy steel and precision-machined by gear hobbing, resulting in high tooth profile accuracy and excellent transmission performance. A worm wheel 10 is rotatably connected to the side wall of the connecting plate 16. The worm wheel 10 is also made of high-strength alloy material and is carefully designed and machined to mesh with the worm 9. A fixing column 12 is fixedly connected inside the worm wheel 10. The fixing column 12 is a solid carbon steel cylinder, and a gear 11 is fixedly connected to its outer wall via welding. Supports 14 are fixedly connected to both ends of the support column 1. The support 14 is stamped from stainless steel sheet and has a rack 13 fixedly connected to its interior via bolts. Strip 13 meshes with gear 11. A lifting column 15 is slidably connected to the outer wall of support column 1. The lifting column 15 adopts a hollow cylindrical structure made of aluminum alloy, which reduces weight and ensures strength. A self-lubricating linear bearing is installed between its inner wall and the outer wall of support column 1 to ensure smooth lifting and low friction. The side wall of connecting plate 16 is fixedly connected to one side of lifting column 15. A connector 17 is fixedly connected to the side wall of lifting column 15. The connector 17 is made of aluminum alloy sheet by CNC machining. Its shape and size are customized according to actual connection requirements. It can be easily connected and cooperated with other parts, thereby realizing multiple functions and operations of the auxiliary tooling for the assembly of the entire engine cylinder head.

[0034] Specifically, when it is necessary to lift or lower an object, the motor 5 is first started to drive the shaft head 6 to rotate, thereby transmitting power to the worm shaft 8, causing it to rotate as well. The worm 9 on the outer wall of the worm shaft 8 also begins to roll. Due to the meshing action between the worm 9 and the worm wheel 10, the worm wheel 10 is driven to rotate. Both the worm 9 and the worm wheel 10 are processed with high tooth profile matching, ensuring the smoothness and efficiency of the transmission. The rack 13 is made of high-quality carbon steel and is fixed at both ends of the support 14 and embedded inside the support column 1, forming a meshing relationship with the gear 11. The fixed column 12 inside the worm wheel 10 is firmly connected to the gear 11. When the worm wheel 10 rotates, the fixed column 12 drives the gear 11 to slide on the rack 13, thus driving the lifting column 15 to move up and down on the outer wall of the support column 1. The lifting column 15 is made of aluminum alloy, which is lightweight and high-strength. Its lifting process drives the housing 3 and the mounting bracket 2 to lift synchronously. This design allows the cylinder head to be adjusted to a suitable height, which facilitates subsequent processing operations. For example, in the drilling and milling processes of the cylinder head, workers no longer need to tediously adjust the position of the cylinder head, saving a lot of time and further improving the overall efficiency of the production line, thus ensuring the efficient production of engine cylinder heads.

[0035] Reference Figure 1 , Figure 4 and Figure 5The housing 3 has a platform 22 fixedly connected inside. The platform 22 is made of high-strength aluminum alloy, possessing good strength and weight, which contributes to the stability and energy efficiency of the overall device. A placement plate 19 is installed on the top of the platform 22. The placement plate 19 is made of high-quality carbon steel and has undergone fine grinding, resulting in a smooth and flat surface to reduce frictional resistance with other components. A fixing seat 23 is fixedly connected to the top of the platform 22. The fixing seat 23 is cast from stainless steel, providing corrosion resistance and structural stability. An electric push rod 24 is fixedly connected to the side wall of the fixing seat 23. The screw and nut assembly inside the electric push rod 24 has high transmission efficiency and precise positioning capability, enabling stable output. Furthermore, the electric actuator 24 has a precise linear thrust. The output end of the electric actuator 24 is fixedly connected to a connecting block 25, which is milled from a single piece of aluminum alloy. Its reasonable shape design effectively transmits the thrust of the electric actuator 24. The housing 3 has a sliding groove 4 inside, the inner wall of which is polished to have low surface roughness, ensuring that the components slidably connected to it can slide. A clamp 18 is fixedly connected to the top of the placement plate 19. The clamp 18 adopts an adjustable mechanical structure, and its main body is made of hardened alloy steel, possessing high hardness and wear resistance. Its clamping part is covered with a rubber buffer pad, which protects the clamped object from damage and increases friction to ensure a firm clamping grip. The outer wall of the plate 18 is slidably connected to the inside of the slide groove 4. One side of the connecting block 25 is fixedly connected to the outer wall of the placement plate 19. The top of the placement plate 19 is fixedly connected to the second support column 26. The second support column 26 is made of round steel pipe with moderate wall thickness and good axial compressive strength. One side of the second support column 26 is rotatably connected to the rotating arm 27. The rotating arm 27 is extruded from high-strength aluminum alloy and is shaped like a curved lever, which can effectively transmit force and change the direction of force. One side of the rotating arm 27 is rotatably connected to the third support column 28. The top of the platform 22 is fixedly connected to the second support 32. The second support 32 is equipped with a rolling bearing. The rotating column 30 is rotatably connected inside the second support 32. The rotating column 30 is made of... Made of solid carbon steel, the platform 22 has a support plate 29 fixedly connected internally by welding. The support plate 29 is formed by stamping steel plate and has good flatness and strength. The bottom of the support column 3 28 is fixedly connected to the top of the support plate 29. The top of the support plate 29 is fixedly connected to the fixing seat 2 31. The top of the platform 22 is fixedly connected to the slider 21. The slider 21 is made of self-lubricating nylon material, which has a low coefficient of friction and good wear resistance. The side wall of the slider 21 is slidably connected to the limit block 20. The limit block 20 is made of aluminum alloy material and is fixedly connected to the side wall of the placement plate 19 by welding on both sides, which can ensure that the placement plate 19 maintains a stable posture during movement and will not shift or shake.

[0036] Specifically, when it is necessary to fix an object, the electric push rod 24 is activated. The motor inside the electric push rod 24 starts running, pushing its telescopic rod to extend, thereby moving the connecting block 25. The connecting block 25 is connected to the placement plate 19, causing the placement plate 19 to move accordingly. Both sides of the placement frame 2 are fixedly connected to the limiting block 20 by welding. During the movement of the placement plate 19, the limiting block 20 slides on the slider 21, ensuring the smoothness and accuracy of the movement. Then, the second support column 26 at the top of the placement plate 19 also begins to move, thereby driving the rotating arm 27 to move to the right. The rotating arm 27 rotates around its connection point with the second support column 26, and then drives the support... Column 3 28 moves, simultaneously causing the rotating column 30 to rotate. At this time, the rotating arm 27 on the other side associated with the rotating column 30 moves to the left, ultimately causing the clamp 18 to move towards the center. This allows the clamps 18 on both sides to clamp the object. The clamp 18 is made of high-strength alloy steel, and its inner clamping surface has been finely polished and equipped with an elastic buffer pad. This provides clamping force to fix the cylinder head, preventing it from shaking due to external forces during processing, and also avoids damage to the cylinder head surface. This ensures that the flatness and roughness of the cylinder head surface meet the design requirements, improves the processing quality and production efficiency of the cylinder head, and provides a guarantee for the entire engine cylinder head assembly process.

[0037] Working principle: When it is necessary to lift or lower an object, the motor 5 is started, which drives the shaft head 6 to rotate, thereby driving the worm shaft 8 to rotate, which in turn drives the worm 9 to roll, which in turn drives the worm wheel 10 to rotate, so that the worm 9 and the worm wheel 10 mesh. The rack 13 is fixed at both ends of the support 14 and embedded inside the support column 1, so that the rack 13 meshes with the gear 11. The worm wheel 10 drives the gear 11 to slide on the rack 13 through the fixed column 12, which can drive the lifting column 15 to rise and fall on the outer wall of the support column 1, thereby driving the housing 3 to rise and fall, and then driving the placement frame 2 to rise and fall. This realizes the adjustment of the cylinder head to a suitable height, which is convenient for processing and further improves the overall efficiency of the production line.

[0038] When it is necessary to fix the object, the electric push rod 24 is activated, which drives the connecting block 25 to move, thereby moving the placement frame 2. Both sides of the placement plate 19 are fixedly connected to the limiting block 20, thereby causing the limiting block 20 to slide on the slider 21. Then, the second support column 26 at the top of the placement plate 19 moves, which in turn drives the rotating arm 27 to move to the right, and then drives the third support column 28 to move, which in turn drives the support plate 29 to move. At the same time, the support plate 29 drives the rotating column 30 to rotate. At this time, the other rotating arm 27 moves to the left, which in turn drives the clamp 18 to move to the middle, so that the clamps 18 on both sides clamp the object and fix the cylinder head through clamping force. Whether in a static state or under the interference of cutting force, vibration and other disturbances during processing, the position can be kept relatively fixed, which improves production efficiency.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
