[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0025] Example 1: Reference Figures 1 to 4This application provides a truss-type press-fitting device for assembling valve lock clips on an engine cylinder head. The engine cylinder head includes valve springs, which are sleeved on the valve lock clips. It also includes a support 1, which includes two frames 11 and a connecting rod 14 connected between the two frames 11. The connecting rod 14 and the frames 11 form a support frame 15. The top beams 111 of the two frames 11 are connected by a horizontal beam 2. The mounting section includes a drive assembly 3 and a valve lock clamp mounting auxiliary tool 4. The drive assembly 3 is slidably mounted on the horizontal crossbeam 2 and is connected to the valve lock clamp mounting auxiliary tool 4. The valve lock clamp installation auxiliary tool 4 has through holes at both ends. The valve lock clamp installation auxiliary tool 4 is used to cover the valve spring and compress the valve spring so that the valve lock clamp passes through and extends out of the through hole. The drive assembly 3 is used to provide the force to compress the valve spring to the valve lock clamp installation auxiliary tool 4.
[0026] In this embodiment, the frame 11 is constructed entirely of welded metal, possessing the structural strength to support the weight of the mounting section and the engine cylinder head. The frame 11 has a rectangular shape, with its four uprights reinforced by diagonal braces, enhancing the overall stability of the frame 11 and preventing swaying during pressing. Two frames 11 are connected by connecting rods 14 to form a support frame 15, which supports the roller conveyor 5.
[0027] The horizontal beam 2 and the top beams 111 of the two frames 11 adopt a guide rail and slider structure. Linear guide rails are installed along the length direction on the top beams 111 of the two frames 11. Adaptive sliders are installed at corresponding positions at the bottom of the horizontal beam 2 to reduce sliding friction and allow the horizontal beam 2 to slide left and right along the top beams 111.
[0028] The drive assembly 3 mainly consists of a power source, a transmission mechanism, and connecting components. The top of the drive assembly 3 is provided with a structure that is adapted to the second slide rail 21 on the horizontal beam 2, so that the drive assembly 3 can slide along the horizontal beam 2.
[0029] The through-hole diameter of the valve lock clamp installation aid 4 is larger than the outer diameter of the valve lock clamp to allow it to pass through smoothly. During the press-fit operation, the valve lock clamp installation aid 4 is aligned with the valve lock clamp, and the drive assembly 3 applies downward pressure to the valve lock clamp installation aid 4. The valve lock clamp installation aid 4 presses down on the valve spring covering the valve lock clamp, gradually compressing the valve spring. Under pressure, the valve lock clamp passes through the through-hole and extends a certain length, at which point it aligns perfectly with the valve lock clamp slot in the engine cylinder head. The valve lock clamp is then installed into the valve lock clamp slot, completing the assembly process. After the valve lock clamp is installed, the pressure is slowly released, the valve spring returns to its original position, and the valve lock clamp installation aid 4 is driven upward by the drive assembly 3 to prepare for the next press-fit operation.
[0030] Using the above technical solution, the frame 11 and connecting rod 14 of bracket 1 can form a stable support structure, and the horizontal beam 2 ensures that the mounting part can slide stably, improving the overall structural rigidity and reducing assembly deviation. The drive assembly 3 and valve lock clamp installation auxiliary tool 4 provide pressure to the valve spring, and guide the valve lock clamp to extend through the through hole of the valve lock clamp installation auxiliary tool 4, which improves the assembly accuracy, simplifies the operation process, reduces labor intensity, and greatly improves production efficiency.
[0031] Example 2: Reference Figure 1 and Figure 2 Furthermore, the bottom of the top beams 111 of the two frames 11 are respectively provided with first slide rails 13, the two ends of the horizontal beam 2 are respectively slidably installed on the two first slide rails 13, the horizontal beam 2 is provided with second slide rails 21, and the drive assembly 3 is slidably installed on the second slide rails 21.
[0032] In this embodiment, the top beams 111 of the two frames 11 are made of sheet metal or steel profiles, possessing the strength and rigidity to bear the weight and force of the subsequent horizontal beams 2 and related components. Mounting grooves for installing the first slide rail 13 are machined along the length of the lower surface of the top beams 111.
[0033] The first slide rail 13 is a linear guide rail, which has guiding and load-bearing capacity. The guide rail is installed in the mounting groove of the top beam 111 by bolts, and the two ends of the horizontal beam 2 are slidably installed on the two first slide rails 13 respectively.
[0034] A second slide rail 21 is installed along the length of the lower surface of the horizontal beam 2. The second slide rail 21 is also a linear guide rail, which provides guidance and support for the drive assembly 3 according to the weight of the mounting part and the load it bears during use. The installation process of the second slide rail 21 is similar to that of the first slide rail 13. First, a corresponding mounting groove is machined on the horizontal beam 2, and then the second slide rail 21 is fixed in the mounting groove with bolts to ensure that its straightness and levelness meet the requirements.
[0035] Example 3: Reference Figure 1 and Figure 2 Furthermore, a second slider 12 is provided at each end of the horizontal beam 2, and the second slider 12 is slidably connected to the first slide rail 13.
[0036] In this embodiment, the first slide rail 13 is installed at the bottom of the top beam 111. The first slide rail 13 consists of a guide rail body and a mounting base. The guide rail body is made of alloy steel. The mounting base is fixed in the mounting groove of the top beam 111 by bolts. Bolts are used in conjunction with flat washers and spring washers to prevent loosening. At the same time, the mounting base is in close contact with the bottom surface of the top beam 111 to avoid gaps between the mounting base and the bottom surface of the beam.
[0037] Limiting devices (not shown in the figure) are provided at both ends of the first slide rail 13, such as limiting blocks. The limiting blocks are fixed to both ends of the mounting base by bolts to limit the sliding range of the horizontal beam 2.
[0038] The second slider 12 is made of aluminum alloy or alloy steel, possessing sufficient strength and rigidity to withstand the load transmitted by the horizontal beam 2 and the components mounted on it. The connection between the second slider 12 and the horizontal beam 2 is achieved using bolts to ensure the relative positional accuracy between them.
[0039] Example 4: Continue to refer to Figure 1 Furthermore, the drive assembly 3 includes a first slider 31, which is slidably mounted on the second slide rail 21; and a cylinder 32, connected to the first slider 31, with the drive shaft of the cylinder 32 running vertically. Figure 1(As shown in the Y direction) The spring rod 33 is set downwards; one end of which is connected to the drive shaft of the cylinder 32. Driven by the drive shaft of the cylinder 32, the spring rod 33 moves downwards in the vertical direction, and the other end of the spring rod 33 abuts against the valve lock clamp installation auxiliary tool 4, providing a force to compress the valve spring to the valve lock clamp installation auxiliary tool 4. The truss-type press-fitting device also includes an extension rod 34. Both ends of the extension rod 34 are respectively provided with threaded holes with internal threads. The drive shafts of the spring rod 33 and the cylinder 32 are respectively provided with external threads that match the internal threads. The extension rod 34 can be threadedly connected to the spring rod 33 and the drive shaft of the cylinder 32 respectively.
[0040] In this embodiment, the first slider 31 is made entirely of metal to maintain structural strength and wear resistance during long-term sliding. The first slider 31 is installed inside the second slide rail 21 to slide within the second slide rail 21.
[0041] The first slider 31 and the cylinder 32 are mechanically connected. A mounting surface is provided at the bottom of the first slider 31, and the top of the cylinder body of the cylinder 32 is fixed to the mounting surface by bolts. During installation, the center line of the drive shaft of the cylinder 32 and the center line of the second slide rail 21 are in the same vertical plane to avoid additional lateral force generated during the driving process of the cylinder 32 due to installation deviation, which would affect the normal operation of the entire drive assembly 3 and the valve lock clamp installation auxiliary tool 4.
[0042] The drive shaft of cylinder 32 is connected to one end of spring rod 33. At the connection point, a lock nut is used for further reinforcement to ensure that the force output by cylinder 32 can be effectively transmitted to valve lock clamp installation auxiliary tool 4 through spring rod 33.
[0043] The spring rod 33 possesses sufficient strength and rigidity, and is manufactured using a metal rod. The cross-sectional shape of the rod can be designed as circular or rectangular depending on the force applied. The length of the spring rod 33 is determined based on the overall layout of the device and the distance between the valve lock clamp installation auxiliary tool 4 and the cylinder 32. While ensuring effective connection and force transmission, its length is reduced to minimize bending deformation that may occur due to excessive rod length.
[0044] The spring rod 33 and the valve lock clamp installation auxiliary tool 4 are in contact. During the driving process of the cylinder 32, the force of the driving shaft of the cylinder 32 can be transmitted to the valve lock clamp installation auxiliary tool 4 along the axial direction of the spring rod 33. This avoids the valve lock clamp installation auxiliary tool 4 from tilting, shaking or other unstable situations caused by eccentric force, which would affect the assembly accuracy of the valve lock clamp.
[0045] The extension rod 34 is made of a similar metal material to the spring rod 33. The extension rod 34 is available in various lengths, such as 100mm, 200mm, and 300mm. The threaded holes at both ends of the extension rod 34 are identical, ensuring versatility. It allows for convenient and quick threaded connections to both the spring rod 33 and the cylinder 32 drive shaft. By selecting and combining extension rods 34 of different lengths according to actual assembly requirements, the adaptability and scalability of this application are improved, facilitating efficient assembly of valve lock clips for different engine cylinder heads.
[0046] Example 5: Continue to refer to Figure 1 Furthermore, an auxiliary positioning component 321 is provided at the bottom of the cylinder 32 to position the engine cylinder head so that the cylinder 32 moves to the top of the engine cylinder head.
[0047] In this embodiment, the auxiliary positioning component 321 is fixed to the bottom of the cylinder 32 by bolts, forming an integral structure with the cylinder 32, and slides on the horizontal beam 2 as the cylinder 32 slides.
[0048] The auxiliary positioning component 321 is usually a proximity sensor, specifically an inductive proximity sensor. When the cylinder 32 moves, the auxiliary positioning component 321 generates a corresponding signal change based on the change in distance between the engine cylinder head and the sensing head of the auxiliary positioning component 321, thereby determining the position of the engine cylinder head until the cylinder 32 is positioned directly above the engine cylinder head for the pressing operation.
[0049] Example 6: Reference Figure 4 Furthermore, the valve lock clamp installation auxiliary tool 4 includes a spring guide sleeve 41 with a through hole inside the spring guide sleeve 41. The specifications of the spring guide sleeve 41 correspond to the valve lock clamp on the engine cylinder head. The valve spring pressure plate 42 has a mounting hole 421. The valve spring pressure plate 42 is set on the spring guide sleeve 41 and fixedly connected to the spring guide sleeve 41. The mounting hole 421 communicates with the through hole. The valve lock clamp passes through the through hole and extends out from the mounting hole 421.
[0050] In this embodiment, the spring guide sleeve 41 is designed as a hollow columnar structure with a through hole inside for the valve lock clamp to pass through. The diameter of the through hole is machined according to the outer diameter of the valve lock clamp to ensure a suitable gap between them. This gap ensures that the valve lock clamp passes through smoothly without causing it to wobble or deviate due to excessive clearance. This gap is controlled at approximately 0.1-0.3 mm.
[0051] The spring guide sleeve 41 is made of metal materials, such as alloy steel or carbon steel. This ensures that the spring guide sleeve 41 maintains its structural integrity under repeated compression forces from the valve spring and friction from the valve lock clamp, preventing easy wear and deformation, and ensuring the stability and accuracy of the valve lock clamp assembly process.
[0052] The number of spring guide sleeves 41 corresponds to the number of valve lock clips on the engine cylinder head. They are distributed on the valve lock clip installation auxiliary tool 4 according to the actual layout of the engine cylinder head valve lock clips. For common four-cylinder and six-cylinder engine cylinder heads, the valve lock clips are often distributed in pairs symmetrically. The spring guide sleeves 41 are also arranged in pairs symmetrically on the valve lock clip installation auxiliary tool 4 accordingly, ensuring that each valve lock clip has a corresponding spring guide sleeve 41 to guide it through and assemble it.
[0053] The valve spring pressure plate 42 has a flat plate structure. Its mounting hole 421 communicates with the through hole of the spring guide sleeve 41. The diameter of the mounting hole 421 is slightly larger than the outer diameter of the valve lock clip to facilitate the valve lock clip to pass smoothly through the through hole and extend to a suitable length through the mounting hole 421, which is convenient for subsequent assembly operations. The edges of the mounting hole 421 are chamfered to prevent the valve lock clip from being scratched or damaged due to sharp edges during extension.
[0054] Example 7: Continue to refer to Figure 4 The valve spring pressure plate 42 is also provided with an abutment groove 43, which is located at the center of the valve spring pressure plate 42, and the other end of the spring pressure rod 33 abuts against the abutment groove 43.
[0055] In this embodiment, the abutment groove 43 provided on the valve spring pressure plate 42 is used to abut against the spring pressure rod 33. The abutment groove 43 is located at the center of the valve spring pressure plate 42, ensuring that the pressure applied by the spring pressure rod 33 can be evenly transmitted to the valve spring pressure plate 42, thereby enabling each spring guide sleeve 41 to exert a guiding and supporting effect on the valve lock clamp.
[0056] When cylinder 32 applies downward pressure through spring rod 33, the other end of spring rod 33 abuts against the abutment groove 43, pushing valve spring plate 42 into contact with the valve spring, transmitting pressure to the valve spring, causing it to begin compression. As the valve spring compresses, the valve lock clips, guided by the through hole of spring guide sleeve 41 and the mounting hole 421 of valve spring plate 42, gradually pass through and extend out of the mounting hole 421 of valve spring plate 42. The valve spring plate 42, through its own structural stability, ensures that the extension position and state of each valve lock clip are relatively consistent, facilitating the subsequent installation of the valve lock clips into the valve lock clip groove of the engine cylinder head using appropriate assembly tools, thus completing the assembly work.
[0057] Example 8: Continue to refer to Figure 3 Furthermore, the truss-type pressing device also includes a roller conveyor 5 and a cylinder head pad 6. The roller conveyor 5 is mounted on a support frame 15 and is used to transport the engine cylinder head from the previous process to the support frame 15. The cylinder head pad 6 is mounted on the roller conveyor 5, and the engine cylinder head is mounted on the cylinder head pad 6. The cylinder head pad 6 moves with the roller conveyor 5 to the support frame 15.
[0058] In this embodiment, the roller conveyor 5 consists of multiple rollers arranged at equal intervals, with both ends of the rollers mounted on the support frame 15. The surface of the rollers is coated with a textured rubber coating to better contact the cylinder head gasket 6, facilitating smooth movement of the cylinder head gasket 6 during conveying and preventing slippage.
[0059] The cylinder head gasket 6 has a larger overall dimension than the bottom contour of the engine cylinder head, ensuring that the engine cylinder head can be placed stably on the cylinder head gasket 6, and a certain edge area is reserved around it to facilitate subsequent operations and cooperation with other components. The cylinder head gasket 6 is placed on rollers and moves with the roller conveyor 5.
[0060] Furthermore, limiting devices (not shown in the figure) are provided on both sides or at the ends of the cylinder head gasket 6. The limiting devices cooperate with the corresponding structure of the roller conveyor 5 to limit the lateral movement range of the cylinder head gasket 6 on the roller conveyor 5, and prevent the cylinder head gasket 6 from leaving the roller conveyor 5 or colliding or interfering with other components due to unexpected situations (such as being subjected to lateral forces). This ensures that the cylinder head gasket 6 always accurately transports the engine cylinder head to the support frame 15 along the predetermined movement path.
[0061] Furthermore, during the process of supporting the engine cylinder head, the cylinder head gasket 6, in addition to its supporting and moving functions, also has a positioning auxiliary function. The surface of the cylinder head gasket 6 is provided with positioning protrusions, which match the corresponding positioning structure at the bottom of the engine cylinder head. When the engine cylinder head is placed on the cylinder head gasket 6, the positioning protrusions cooperate with the corresponding parts of the cylinder head to position the engine cylinder head, so that it maintains a relatively fixed position during the movement of the cylinder head gasket 6. This facilitates the subsequent precise locking of the engine cylinder head position, so that the cylinder 32 can be accurately positioned directly above the engine cylinder head to carry out the valve lock clamp assembly work.
[0062] Furthermore, the surface of the cylinder head gasket 6 is treated with an anti-slip texture to further enhance the stability of the engine cylinder head when placed on it. In addition, if wear or scratches occur on the surface of the cylinder head gasket 6 during long-term use, it is easy to replace it, so as to ensure the normal operation of the entire transportation and assembly process.
[0063] Furthermore, the engine cylinder head is placed on the cylinder head pad 6. As the roller conveyor 5 rotates, the cylinder head pad 6 moves the cylinder head towards the support frame 15. During this process, the cylinder head pad 6 works closely with the power transmission system of the roller conveyor 5, relying on the rotation of the rollers to provide stable moving power, ensuring that the cylinder head is transported at a preset speed and direction.
[0064] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
