[0002] In the complex and precise manufacturing and assembly process of cylinder heads, spring installation is undoubtedly a crucial step. As one of the core components of an engine, the cylinder head has a compact internal structure, and the precision requirements for the fit between various parts are extremely high. Springs play an indispensable role in this process.

[0003] A search revealed that patent publication number CN206010338U discloses a structure for assembling spring coils on automotive gear shift shafts. This structure includes a frame, a cylinder, a linear guide, an automatic retracting claw, a tapered sleeve, a tapered sleeve fixing fixture, and a product shaft fixing fixture. The product shaft is placed into the fixing fixture, the tapered sleeve is fitted onto the product shaft, and the spring coil is placed inside. The cylinder drives the automatic retracting claw to press the spring coil into the fixed position on the product shaft. The automatic retracting claw can accommodate spring coils of different diameters. During the pressing process, the linear guide provides guidance, ensuring excellent concentricity. The inventors discovered the following problems with the existing technology during the development of this invention:

[0004] When installing springs inside the cylinder head, manual installation is often used, which is not only inefficient but also poses a safety hazard due to the springs' high elasticity, potentially causing them to spring out and injure people. Furthermore, manual installation makes it difficult to ensure the accuracy and consistency of spring installation, which can lead to unstable cylinder head performance and affect the overall engine performance.

[0005] Therefore, a cylinder head spring mounting device is proposed to address the above-mentioned problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a cylinder head spring mounting device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cylinder head spring mounting device, including a support base. Fixed vertical plates are welded and fixed to the upper left and right ends of the support base, respectively. The fixed vertical plates are arranged opposite each other. A fixed rod is welded and fixed to the opposite side of the fixed vertical plates. A support base is movably sleeved on the outer side of the fixed rod. A placement plate is bolted and fixed to the top of the support base. A vertical rod is vertically fixed and welded to the middle of the upper side of the support base. A top plate is also welded and fixed to the top of the vertical rod. A cylinder is placed at the bottom of the top plate via a positioning frame. A telescopic rod is movably mounted at the output end of the cylinder. A support plate is detachably connected to the bottom of the telescopic rod via a positioning plate. Multiple threaded holes are evenly formed on the upper surface of the support plate. A positioning screw is threaded into the internal threads of each threaded hole. A support rod is provided at the bottom of the positioning screw. An mounting sleeve is fixedly installed at the bottom of the support rod.

[0008] Preferably, a protective plate is fixedly installed above the support base, and two fixed vertical plates are symmetrically located on the left and right sides of the protective plate, and the protective plate is tightly connected to the support base.

[0009] Preferably, a limiting hole is provided on the upper side of the fixed vertical plate, and a pin is installed inside the limiting hole in a detachable manner, wherein the outer diameter of the pin is tightly fitted with the inner diameter of the limiting hole.

[0010] Preferably, the pins on the fixed vertical plate are not only partially embedded, but penetrate the entire fixed vertical plate. The bottom of the pins is in direct contact with the upper surface of the placement plate. At the same time, multiple through holes are evenly provided on the upper side of the placement plate.

[0011] Preferably, the vertical rod is perpendicular to the upper surface of the bearing seat, and the two vertical rods are located on both sides of the fixed vertical plate, and the vertical rods cooperate with the fixed vertical plate.

[0012] Preferably, protective rings are fixedly installed at both ends of the bearing plate. There is a certain gap between the inner wall of the protective ring and the outer wall of the vertical rod, and the two do not contact each other. During the operation of the device, the protective ring can slide smoothly along the outer side of the vertical rod.

[0013] Preferably, the positioning screw is rotated to move up and down within the threaded hole of the support plate, while the mounting sleeve is installed in a direction perpendicular to the placement plate.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] Compared with existing technologies, this cylinder head spring mounting device uses a cylinder to drive a telescopic rod to quickly press down the support plate, which can quickly complete the spring installation action. Compared with manual installation, it significantly shortens the installation time of a single spring and significantly improves the overall installation efficiency, which can meet the demand for high-efficiency output in large-scale production.

[0016] Compared with existing technologies, this cylinder head spring mounting device offers several advantages in terms of safety. The protective plate above the support seat effectively blocks the spring from popping out during installation, preventing injury to operators. The protective rings at both ends of the support plate slide smoothly along the outside of the vertical rod during device operation, providing stability and protection, further ensuring operational safety.

[0017] To ensure installation accuracy and consistency, the fixed vertical plate, fixed rod, and support base work together, and the pins precisely limit the placement of the mounting plate, ensuring the accurate positioning of the cylinder head. By rotating the positioning screw, which moves up and down within the threaded hole of the bearing plate, the height of the mounting sleeve can be precisely adjusted, ensuring the accurate installation position of the spring. Simultaneously, the stable downward pressure provided by the cylinder and the mounting sleeve's perpendicularity to the mounting plate ensure consistent force and position during each spring installation, improving the cylinder head assembly quality and contributing to stable engine operation.

Example

[0026] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0027] In a preferred embodiment, a protective plate 2 is fixedly installed above the support base 1, and two fixed vertical plates 3 are symmetrically located on the left and right sides of the protective plate 2. The protective plate 2 is closely connected to the support base 1, providing a stable support structure for the components to be installed later. The protective plate 2 and the fixed vertical plates 3 cooperate with each other to form a relatively regular layout with certain protective functions under the device.

[0028] In a preferred embodiment, mounting grooves are provided at both ends of the support base 5. The bearing 6 is detachably installed inside the mounting groove by bolt fasteners, which facilitates the subsequent replacement or maintenance of the bearing 6. The bearing 6 has good rotation performance. The inner ring of the bearing 6 fits tightly and contacts the outer surface of the fixing rod 4. When the support base 5 needs to move, the bearing 6 can roll smoothly along the fixing rod 4, effectively reducing friction and making the movement of the support base 5 more stable and flexible.

[0029] In a preferred embodiment, a limiting hole 8 is horizontally formed on the upper side of the fixed vertical plate 3. The size of the limiting hole 8 is adapted to the components to be installed laterally. A pin 9 is installed inside the limiting hole 8 in a detachable manner. The outer diameter of the pin 9 is in close fit with the inner diameter of the limiting hole 8. Installation and disassembly operations can be easily achieved by inserting or removing the pin 9. This design provides a flexible limiting means for adjusting or fixing the device.

[0030] In a preferred embodiment, the pins 9 provided on the fixed vertical plate 3 are not only partially embedded, but penetrate the entire fixed vertical plate 3. Both ends of the pins 9 protrude a certain length, which enhances the stability of the installation. The bottom of the pins 9 is in direct contact with the upper surface of the placement plate 7, which plays a limiting and supporting role, preventing the placement plate 7 from moving too high or shaking. At the same time, multiple through holes 10 are evenly opened on the upper side of the placement plate 7. The through holes 10 are of the same size and distributed regularly, which can be used to pass through fasteners such as bolts, making it convenient to install other components or perform fixing operations on the placement plate 7.

[0031] In a preferred embodiment, the vertical rod 11 is perpendicular to the upper surface of the support base 1, ensuring a vertical relationship with the support base 1 and providing a stable vertical support structure for the entire device. The two vertical rods 11 are located on both sides of the fixed vertical plate 3. The vertical rods 11 and the fixed vertical plate 3 cooperate with each other to form a reasonable support frame in terms of spatial layout. This not only makes the device structure more stable, but also provides a reliable support foundation for other components installed on the vertical rods 11, ensuring the overall stability of the device operation.

[0032] In a preferred embodiment, protective rings 16 are fixedly installed at both ends of the support plate 15. The protective rings 16 are made of high-strength and wear-resistant materials, which can effectively protect the ends of the support plate 15. A certain gap is left between the inner wall of the protective ring 16 and the outer wall of the vertical rod 11, and the two do not contact each other, thus avoiding friction and wear caused by direct contact. During the operation of the device, the protective rings 16 can slide smoothly along the outer side of the vertical rod 11, which not only provides guidance for the movement of the support plate 15, but also prevents the support plate 15 from shifting to a certain extent, thus ensuring the stable operation of the device.

[0033] In a preferred embodiment, the positioning screw 18 is rotated to move up and down within the threaded hole 17 of the bearing plate 15, thereby achieving a suitable installation position. The positioning screw 18 has flexible adjustment characteristics and can be adjusted according to the actual cylinder type used. Operators can adjust the displacement according to the size of different cylinders, installation requirements, etc. The mounting sleeve 20 is installed in a direction perpendicular to the placement plate 7, ensuring the verticality of the mounting sleeve 20. This allows the components subsequently installed on the mounting sleeve 20 to maintain a reasonable spatial relationship with the placement plate 7, meeting the overall installation and operation requirements of the device.

[0034] The working process of this utility model is as follows: First, the cylinder head is placed on the placement plate 7. The placement plate 7 is fixed to the top of the support base 5 with bolts. The bearings 6 in the mounting slots at both ends of the support base 5 are fitted onto the fixing rods 4 and can move along the fixing rods 4. The fixing rods 4 are fixed to the opposing fixing vertical plates 3 by welding. The fixing vertical plates 3 are welded to the left and right ends above the bearing base 1. A protective plate 2 is also fixed above the bearing base 1, and the fixing vertical plates 3 are located on the left and right sides of the protective plate 2. Next, the pin 9 is passed through the horizontally opened limiting hole 8 on the upper side of the fixing vertical plate 3. The pin 9 penetrates the entire fixing vertical plate 3, so that its bottom directly contacts the upper surface of the placement plate 7, thus limiting and fixing the placement plate 7. Multiple through holes 10 are evenly opened on the upper side of the placement plate 7 for easy operation. Then, the cylinder 13 is started. The output end of cylinder 13 drives telescopic rod 14 to move downward. The bottom of telescopic rod 14 is detachably connected to bearing plate 15 through positioning plate. Protective rings 16 fixedly installed at both ends of bearing plate 15 can slide smoothly along the outside of vertical rod 11 perpendicular to the upper surface of bearing seat 1. Vertical rod 11 is welded to the middle position on the upper side of bearing seat 1, and the two vertical rods 11 are respectively located on both sides of fixed vertical plate 3, cooperating with fixed vertical plate 3 to adjust bearing plate 15 to a suitable height. Finally, rotate positioning screw 18 to move up and down in multiple threaded holes 17 evenly opened on the upper surface of bearing plate 15. Support rod 19 is provided at the bottom of positioning screw 18, and mounting sleeve 20 is fixedly installed at the bottom of support rod 19. Align mounting sleeve 20 with cylinder head spring mounting position in a direction perpendicular to placement plate 7 to complete spring installation.

[0035] The principle behind the protective ring preventing the load-bearing plate from shifting:

[0036] The main function of the protective ring is to prevent the load-bearing plate from shifting during movement, thereby ensuring the accuracy of the spring installation. Its working principle is as follows:

[0037] Guiding function: A certain gap is left between the inner wall of the protective ring and the outer wall of the vertical rod, allowing the bearing plate to slide smoothly along the outer side of the vertical rod. This design is equivalent to providing a guide track for the bearing plate, restricting its lateral movement and thus preventing it from deviating.

[0038] Limiting function: The gap between the protective ring and the vertical rod is usually designed to be relatively small, which can effectively limit the lateral displacement range of the load-bearing plate. Even if the load-bearing plate is subjected to external forces during movement, the protective ring can limit it within a certain range, preventing it from deviating too far and affecting the accuracy of the spring installation;

[0039] The protective area of ​​the protective ring:

[0040] The protective ring typically covers the entire end of the load-bearing plate, including its edges and sides. This is primarily because:

[0041] Protecting the edges of the load-bearing plate: The edges of the load-bearing plate are its weakest point and are easily damaged by impacts or abrasions. Protective rings effectively protect the edges of the load-bearing plate from damage.

[0042] Preventing load-bearing plate deformation: The protective ring restricts the lateral displacement of the load-bearing plate, thus preventing deformation. This is crucial for ensuring the accuracy of spring installation;

[0043] Improving device stability: The protective ring connects the load-bearing plate and the vertical rod together, improving the stability of the entire device and making it more stable and reliable during operation;

[0044] The protective ring effectively prevents the support plate from shifting during movement by guiding and restricting its movement, ensuring the accuracy of spring installation. Its protection range covers the entire end of the support plate, improving the stability and reliability of the device.
