Description

Technical Field

[0001] This utility model relates to the field of cylinder head press-fitting technology, and more specifically, to a cylinder head seat press-fitting device that prevents misalignment. Background Technology

[0002] The cylinder head is mounted on top of the cylinder block, sealing the cylinder from above and forming the combustion chamber. It is frequently in contact with high-temperature, high-pressure combustion gases, thus bearing significant thermal and mechanical loads. During cylinder head manufacturing, press-fitting equipment is often used to install the cylinder head seat rings. For example, application number "CN202220059373.6" proposes an automotive cylinder head seat ring press-fitting device, relating to the field of automotive cylinder head manufacturing technology. This utility model includes a main body of the device, with a first support column and a second support column arranged side-by-side above the main body. A connecting plate is mounted above the first and second support columns, and a press-fitting assembly is located below the connecting plate. A positioning assembly is located below the press-fitting assembly. The press-fitting assembly includes a cylinder and a pressure plate, with the cylinder located below the connecting plate.

[0003] However, the above-mentioned technical solutions lack a structural design for precise positioning and effective anti-displacement of the cylinder head seat ring during press-fitting. They rely solely on simple positioning components to clamp and position the cylinder head, but cannot clamp and position the seat ring. This makes it difficult to ensure that the seat ring maintains a precise position throughout the press-fitting process, and it is prone to displacement. This reduces the fit accuracy between the seat ring and the cylinder head, affecting the overall performance and sealing effect of the cylinder head. Therefore, we propose an anti-displacement cylinder head seat ring press-fitting device to solve the above problems. Utility Model Content

[0004] The main objective of this invention is to provide a cylinder head seat ring pressing device that prevents misalignment. This device solves the problem of lacking a structural design for precise positioning and effective anti-misalignment of the seat ring during cylinder head seat ring pressing. It relies solely on simple positioning components to clamp and position the cylinder head, but cannot clamp and position the seat ring. This makes it difficult to ensure that the seat ring maintains a precise position during the pressing process, which can easily lead to misalignment. Consequently, the fit between the seat ring and the cylinder head decreases, affecting the overall performance and sealing effect of the cylinder head.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A cylinder head seat press-fitting device for preventing misalignment includes a support platform. A support frame is mounted on the rear end of the upper surface of the support platform. A cross-shaped electric slide rail is mounted on the lower end of the support frame. A first slider is mounted on the lower end of the cross-shaped electric slide rail. A press-fitting mechanism is mounted on the lower end of the first slider. The lower end of the press-fitting mechanism engages with raw materials. A storage box is mounted on one side of the rear end of the upper surface of the support platform. The press-fitting mechanism includes a cylinder, which is installed inside the first slider. A push rod is mounted on the output end of the cylinder. A first connecting plate is movably sleeved on the outer side of the push rod. The lower surface of the first connecting plate is movable. A plurality of clamping blocks are movably installed. The raw material is clamped and installed at the lower end of the clamping blocks. The lower end of each clamping block is provided with a guide groove. A pressing block is movably installed inside each guide groove. The pressing block and the raw material are vertically aligned. A second connecting plate is movably installed between the clamping blocks. The second connecting plate is provided with a plurality of temporary storage grooves. The ends of the pressing blocks that are close to each other are respectively engaged inside the temporary storage grooves. A hydraulic cylinder is installed at the lower end of the push rod. The output end of the hydraulic cylinder movably passes through the lower end of the push rod and is fitted with a pressure plate. The pressure plate and the second connecting plate are vertically aligned.

[0007] Preferably, the push rod has several positioning grooves on its outer side, and positioning blocks are respectively installed inside the first connecting plate and at one end near the positioning groove. The positioning blocks are respectively engaged and installed inside the positioning groove.

[0008] Preferably, the lower surface of the first connecting plate is provided with a sliding groove, and a second slider is movably installed inside the sliding groove. The lower ends of the second sliders are connected to the clamping blocks. A first guide rod is installed at both ends inside the sliding groove, and the rod body of the first guide rod is movably installed through the inside of the second slider.

[0009] Preferably, springs are fitted on the outer side of the first guide rod near one end of the push rod. The two ends of the springs are respectively in contact with the second slider and the slide groove. The lower end of the positioning block is provided with a groove. A connecting rope is movably installed between the groove and the slide groove. The two ends of the connecting rope are respectively connected to the second slider and the push rod.

[0010] Preferably, a second guide rod is installed inside the guide groove, and the rod body of the second guide rod is movably installed inside the press block.

[0011] Preferably, a tension spring is fitted onto the upper end of the second guide rod, and the upper and lower ends of the tension spring are connected to the guide groove and the press block, respectively.

[0012] Preferably, electric push rods are installed at both ends of the upper surface of the first connecting plate, and clamping frames are installed at the output ends of the electric push rods, with the clamping frames clamping and connecting to the rod body.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) In this utility model, the seat ring can be accurately positioned by the combination of clamping block, positioning groove, positioning block and other structures. When the cylinder pushes the push rod to move down, the push rod pulls the connecting rope so that the second slider drives the clamping block to clamp the raw material. The raw material is fixed stably before pressing, which greatly reduces the possibility of seat ring displacement during pressing, improves the fitting accuracy between the seat ring and the cylinder head, and thus ensures the overall performance and sealing effect of the cylinder head.

[0015] (2) In this utility model, the cross electric slide rail cooperates with the first slider to accurately move the raw material to the installation position, so that the raw material and the installation position are accurately aligned. The hydraulic cylinder pushes the pressure plate and the second connecting plate to move down, and the second connecting plate drives the pressing block to press. The whole process is smooth and orderly, reducing rework caused by deviation and improving pressing efficiency. At the same time, under the action of the second guide rod and the tension spring, the pressing block moves stably in the guide groove, further ensuring the stability and reliability of the pressing process.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0026] like Figures 1 to 8As shown in the figure, this utility model embodiment proposes a cylinder head seat pressing device to prevent displacement, including a support platform 1, a support frame 2 installed at the rear end of the upper surface of the support platform 1, a cross electric slide rail 3 installed at the lower end of the support frame 2, a first slider 4 installed at the lower end of the cross electric slide rail 3, a pressing mechanism 5 installed at the lower end of the first slider 4, a raw material 7 engaged at the lower end of the pressing mechanism 5, a storage box 6 installed on one side of the rear end of the upper surface of the support platform 1, and the pressing mechanism 5 including a cylinder 501 installed inside the first slider 4. A push rod 502 is installed at the output end of the cylinder 501, a first connecting plate 503 is movably sleeved on the outer side of the push rod 502, and several clamps are movably installed on the lower surface of the first connecting plate 503. The material 7 is clamped and installed inside the lower end of the clamping block 512. The lower end of the clamping block 512 is provided with guide grooves 513. Pressing blocks 516 are movably installed inside the guide grooves 513. The pressing blocks 516 and the material 7 overlap vertically. The clamping blocks 512 are movably installed with a second connecting plate 517. The second connecting plate 517 is provided with several temporary storage grooves 518. The ends of the pressing blocks 516 that are close to each other are respectively engaged inside the temporary storage grooves 518. The lower end of the push rod 502 is equipped with a hydraulic cylinder 519. The output end of the hydraulic cylinder 519 movably passes through the lower end of the push rod 502 and is equipped with a pressure plate 520. The pressure plate 520 overlaps vertically with the second connecting plate 517.

[0027] like Figures 4 to 8As shown, in another embodiment of this utility model, the outer side of the push rod 502 is provided with several positioning grooves 504. Positioning blocks 505 are respectively installed inside the first connecting plate 503 and near one end of the positioning groove 504. The positioning blocks 505 are respectively engaged inside the positioning groove 504. The lower surface of the first connecting plate 503 is provided with a sliding groove 506. Second sliders 508 are movably installed inside the sliding groove 506. The lower ends of the second sliders 508 are respectively connected to clamping blocks 512. First guide rods 509 are respectively installed at both ends inside the sliding groove 506. The rods of the first guide rods 509 are movably inserted through the interior of the second sliders 508. Springs 510 are respectively sleeved on the outer side of the first guide rod 509 near one end of the push rod 502. The two ends of the springs 510 are respectively connected to the second sliders 508. The 08 and the slide 506 are fitted together. The lower end of the positioning block 505 is provided with a groove 507. A connecting rope 511 is movably installed between the groove 507 and the slide 506. The two ends of the connecting rope 511 are connected to the second slider 508 and the push rod 502 respectively. The inside of the guide groove 513 is provided with a second guide rod 514. The rod body of the second guide rod 514 is movably installed inside the pressing block 516. The upper end of the rod body of the second guide rod 514 is fitted with a tension spring 515. The upper and lower ends of the tension spring 515 are connected to the guide groove 513 and the pressing block 516 respectively. The upper surface of the first connecting plate 503 is provided with an electric push rod 521 at both ends. The output end of the electric push rod 521 is provided with a clamping frame 522. The clamping frame 522 is clamped and connected to the rod body of the push rod 502.

[0028] First, the clamping block 512 is moved to the upper end of the raw material 7 by the cooperation of the cross electric slide rail 3 and the first slider 4. Then, as the cylinder 501 pushes the push rod 502 downward, the push rod first moves the clamping block 512 downward, allowing the clamping block 512 to be inserted into the storage box 6, and at the same time, the raw material 7 is clamped between the clamping blocks 512. Then, as the push rod 502 continues to move downward, it pulls the connecting rope 511 to move. The connecting rope 511 then pulls the second slider 508 to move, thereby allowing the second slider 508 to move the clamping block 512 to feed the raw material 7. During clamping, the second slider 508 also compresses the spring 510. After the material 7 is clamped, the electric push rod 521 can push the clamping frame 522 to move, so that the clamping frame 522 clamps and positions the push rod 502. Thus, when the cylinder 501 pulls the push rod 502 to move upward, the push rod 502 does not need to move along the positioning block 505 and the positioning groove 504. Instead, the push rod 502 directly drives the first connecting plate 503 and the clamping block 512 to move upward through the clamping frame 522, so that the clamping block 512 can stably clamp the material 7.

[0029] Then, the cross-shaped electric slide rail 3, in conjunction with the first slider 4, moves the raw material 7 to the upper end of the required installation position. Then, the cylinder 501 pushes the push rod 502 and the first connecting plate 503 to move downward, so that the clamping block 512 moves the raw material 7 to the upper end of the required installation position and makes them fit together. Then, the hydraulic cylinder 519 pushes the pressure plate 520 to move downward, so that the pressure plate 520 pushes the second connecting plate 517 and the pressing block 516 to move downward, so that the pressing block 516 stretches the tension spring 515 and presses the raw material 7 into the inside of the cylinder head along the guide groove 513, thus completing the pressing work.

[0030] Then, after the pressing is completed, the hydraulic cylinder 519 pulls the pressure plate 520 to move upward, and the tension spring 515 will also pull the second connecting plate 517 and the pressing block 516 to move upward, so as to control the pressing block 516 to perform the reset work.

[0031] The temporary storage groove 518 is used to assist in storing one end of the pressing block 516. When the second slider 508 works with the slide groove 506 to drive the clamping block 512 to adjust its position, the second guide rod 514 will also drive the pressing block 516 to adjust its length, so that it can achieve the telescopic adjustment function by following the position change of the clamping block 512. This can not only achieve clamping and positioning of raw materials 7 of various sizes, but also facilitate the pressure plate 520 to work with the second connecting plate 517 to press down multiple clamping blocks 512 synchronously, so that the force is more even.

[0032] When the cylinder 501 drives the push rod 502 to move upward, causing the push rod 502 to separate the clamping block 512 from the cylinder head, the electric push rod 521 can drive the clamping frame 522 to reset, so that the clamping frame 522 separates from the push rod 502. Then the first connecting plate 503 can move downward by its own weight, and at the same time the spring 510 will push the second slider 508 to expand outward, thereby realizing the reset of the first connecting plate 503 and the clamping frame 522, so that it can continue to clamp and transport new raw materials 7.

[0033] The working principle of this anti-displacement cylinder head seat press-fitting equipment:

[0034] In use, firstly, the clamping block 512 is moved to the upper end of the raw material 7 by the cooperation of the cross electric slide rail 3 and the first slider 4. Then, as the cylinder 501 pushes the push rod 502 downward, the push rod first moves the clamping block 512 downward, allowing the clamping block 512 to be inserted into the storage box 6, and at the same time, the raw material 7 is inserted between the clamping blocks 512. Then, as the push rod 502 continues to move downward, it pulls the connecting rope 511 to move, and then the connecting rope 511 pulls the second slider 508 to move, so that the second slider 508 moves the clamping block 512 to the upper end of the raw material 7. Material 7 is clamped, and at the same time, the second slider 508 will also squeeze the spring 510. After the material 7 is clamped, the electric push rod 521 can push the clamping frame 522 to move, so that the clamping frame 522 clamps and positions the push rod 502. Thus, when the cylinder 501 pulls the push rod 502 to move upward, the push rod 502 does not need to move along the positioning block 505 and the positioning groove 504. The push rod 502 directly drives the first connecting plate 503 and the clamping block 512 to move upward through the clamping frame 522, so that the clamping block 512 can stably clamp the material 7.

[0035] Then, the cross-shaped electric slide rail 3, in conjunction with the first slider 4, moves the raw material 7 to the upper end of the required installation position. Then, the cylinder 501 pushes the push rod 502 and the first connecting plate 503 to move downward, allowing the clamping block 512 to move the raw material 7 to the upper end of the required installation position so that they fit together. Then, the hydraulic cylinder 519 pushes the pressure plate 520 to move downward, allowing the pressure plate 520 to push the second connecting plate 517 and the pressing block 516 to move downward, so that the pressing block 516 stretches the tension spring 515 and presses the raw material 7 into the inside of the cylinder head along the guide groove 513, completing the pressing work.

[0036] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
