Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0020] The following is in conjunction with the appendix Figure 1-9 To further describe this application in detail, a cylinder head press-fitting fixture includes a base 1, a first placement frame 2, a second placement frame 3, a press 4, an adjustment mechanism 5, a first positioning mechanism 6, and a press 7. The base 1 is installed on the lower part of the press 4, the first placement frame 2 and the second placement frame 3 are respectively installed on the upper part of the base 1, the press 7 is installed on the upper part of the press 4, and the output end of the press 7 is connected to a press head 8. The adjustment mechanism 5 and the first positioning mechanism 6 are respectively installed on the first placement frame 2 and the second placement frame 3.

[0021] Furthermore, the first placement rack 2 is provided with a plurality of spaced first placement seats 21, the first placement rack 2 is provided with first stops 22 on both sides, and the bottom of the first placement rack 2 is provided with a plurality of second positioning mechanisms 23.

[0022] The spaced first placement seat 21 can place multiple cylinder heads 9 at the same time, improving tooling utilization; anti-offset limiting: the first stop blocks 22 on both sides form a physical limit to prevent the cylinder head 9 from sliding laterally during placement or pressing, ensuring operational safety; secondary positioning reinforcement: the bottom second positioning mechanism 23 (such as positioning seat 231 and second positioning pin 232) fixes the first placement frame 2 to the base 1, preventing the placement frame itself from shifting and further improving positioning accuracy.

[0023] Furthermore, the second placement rack 3 is provided with a plurality of spaced second placement seats 31, the first placement rack 2 is provided with second blocks 32 on both sides, and the bottom of the second placement rack 3 is provided with a plurality of third positioning mechanisms 33.

[0024] The second placement rack 3 has a similar structure to the first placement rack 2 and can simultaneously carry workpieces, realizing parallel pressing at two workstations and doubling production efficiency; Standardized limiting: The second stop block 32 cooperates with the second placement seat 31 to ensure that the cylinder head 9 is placed in the same direction, reducing clamping errors; Layered positioning system: The third positioning mechanism 33 works in conjunction with the second positioning mechanism 23 to fix the first placement rack 2 / second placement rack 3 respectively, forming a three-level positioning of base 1-placement rack-workpiece, improving overall stability.

[0025] Furthermore, the first placement rack 2 and the second placement rack 3 have the same structure. The first placement rack 2 includes an inclined plate 24 and two mounting seats 25, with both ends of the inclined plate 24 mounted on the mounting seats 25.

[0026] The first placement rack 2 and the second placement rack 3 have the same structure, which facilitates the interchangeability and maintenance of parts and reduces tooling costs; inclined plate guiding function: the inclined plate 24 is designed to use gravity to assist in the positioning of the cylinder head 9, so that the workpiece naturally fits the inclined plate, and the tilt angle makes it easy for the pressure head 8 to be vertically aligned with the seat ring mounting hole; adjustable mounting base: the inclined plate 24 is fixed by the mounting base 25, and the tilt requirements of different models of cylinder heads 9 can be adapted by adjusting the height or angle of the mounting base 25, thereby improving the versatility of tooling.

[0027] Furthermore, the adjustment mechanism 5 includes a cylinder 51 and a top head 52. The cylinder 51 is fixed on the inclined plate 24 by a mounting bracket I 53, and the output end of the cylinder 51 is fixed to the top head 52.

[0028] The cylinder 51 drives the top head 52 to precisely control the thrust and make fine adjustments to the position of the cylinder head 9 after placement, compensating for minor deviations in manual clamping; dynamic adaptability: the adjustment mechanism 5 can compensate for the dimensional tolerances of different cylinder heads 9 in real time, ensuring the consistency of the seat ring pressing position; high-efficiency drive: the cylinder 51 has a fast response speed and stable thrust, which is more efficient than manual adjustment and is suitable for automated production lines.

[0029] Furthermore, the first positioning mechanism 6 includes a first positioning pin 61, which is fixed to the inclined plate 24 by a mounting bracket II 62. The first positioning pin 61 is inserted into the positioning hole of the cylinder head 9 to form a rigid positioning reference, ensuring the coaxiality of the seat ring press-fit position with the cylinder head 9 structure; the shape of the positioning pin matches the positioning hole of the cylinder head 9, which can prevent the workpiece from being installed backwards or misaligned, improving assembly reliability; the positioning pin is fixed to the inclined plate 24, and the workpiece can be directly inserted into the first positioning pin 61 when placed, reducing clamping time.

[0030] Furthermore, the second positioning mechanism 23 and the third positioning mechanism 33 have the same structure. The second positioning mechanism 23 includes a positioning seat 231 and a second positioning pin 232, with the second positioning pin 232 connected to the positioning seat 231. The second positioning mechanism 23 / third positioning mechanism 33 connects to the base 1 via the positioning seat 231 and the second positioning pin 232, locking the placement frame and preventing displacement of the placement frame due to reaction force during pressing. The rigid positioning from the base 1 to the placement frame ensures that the workpiece positioning accuracy is not lost due to the shaking of the placement frame, which is especially suitable for high-precision pressing scenarios. The detachable structure of the positioning seat 231 and the second positioning pin 232 facilitates replacement after wear, reducing tooling maintenance costs.

[0031] The beneficial effects of this utility model are as follows: By setting the first positioning mechanism 6, the second positioning mechanism 23 and the third positioning mechanism 33, this utility model achieves precise positioning of the cylinder head 9 and the seat ring, ensuring the pressing quality and enhancing versatility; the first placement frame 2 and the second placement frame 3 have the same structure and are equipped with an adjustable adjustment mechanism 5, which can adapt to different models of cylinder heads 9 and seat rings, improving pressing efficiency; the pressing is performed using a press 7, which is simple and quick to operate, greatly improving production efficiency, and the structure is simple and reliable; the overall structure of the tooling is simple, the components are firmly connected, the operation is stable and reliable, and the maintenance cost is reduced.

[0032] Working Principle: When using this fixture to press-fit the cylinder head 9 seat ring, the cylinder head 9 is placed on the first placement seat 21 of the first placement frame 2, and positioned by the first positioning mechanism 6 and the second positioning mechanism 23. Then, the seat ring is placed on the second placement seat 31 of the second placement frame 3, and positioned by the first positioning mechanism 6 and the third positioning mechanism 33. Next, the positions of the cylinder head 9 and the seat ring are finely adjusted by the adjusting mechanism 5 to ensure precise alignment between the seat ring and the mounting holes on the cylinder head 9. The press 7 is started, and the press head 8 of the press 7 moves downward, pressing the seat ring into the mounting holes of the cylinder head 9, completing the pressing operation. The workpiece is then loaded as required; the seat ring and press head 8 are positioned; the press 7 is started to press the seat ring, the position of the press head 8 is changed, and pressing continues. After pressing is completed, the workpiece is removed.

[0033] The foregoing has shown and described the basic principles, key features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
