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

[0026] 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.

[0027] The following is in conjunction with the appendix Figure 1-11To further describe this application in detail, a through-type cylinder camshaft bushing press-fitting device includes a base 1, a support frame 2, a lifting mechanism 3, a conveyor frame 4, a press-fitting machine 5, and a top frame 6. The support frame 2 is mounted on the base 1, the lifting mechanism 3 is mounted in the middle of the base 1, the conveyor frame 4 is mounted in the middle of the support frame 2 and placed above the lifting mechanism 3, and the press-fitting machine 5 is mounted on both sides of the upper end of the support frame 2. The top frame 6 is mounted on the upper end of the support frame 2.

[0028] By integrating the base 1, support frame 2, lifting mechanism 3, conveyor frame 4, press machine 5, and top frame 6, an integrated through-type press device is formed, realizing the automated conveying and press-fitting of cylinder camshaft bushings, reducing manual intervention and improving production efficiency; the coordinated cooperation of each component ensures the stability and continuity of the press-fitting process and improves the overall processing accuracy.

[0029] Furthermore, the lifting mechanism 3 includes a support 31, a lifting cylinder 32, and a top frame 33. The lifting cylinder 32 is fixed to the lower part of the support 31, and the output end of the lifting cylinder 32 is fixed to the top frame 33. A plurality of guide frames 34 are provided between the top frame 33 and the support 31. In the lifting mechanism 3, the lifting cylinder 32 provides stable power to the top frame 33. Combined with the guide frames 34, it effectively limits the lifting trajectory of the top frame 33, preventing the top frame 33 from deviating, ensuring a smooth cylinder lifting process, improving the accuracy of cylinder positioning, and providing a reliable foundation for subsequent pressing processes. Furthermore, the top frame 33 includes a top plate 331 and a plurality of push rods 332, with the top plate 331 having a plurality of push rods 332. The top plate 331 of the top frame 33 cooperates with several top rods 332 to flexibly contact and support the cylinder body according to the bottom structure of the cylinder body, increase the contact area with the cylinder body, avoid excessive local stress that could cause cylinder body deformation, and at the same time improve the stability of the lifting process to ensure the cylinder body is raised and lowered horizontally.

[0030] Furthermore, the guide frame 34 includes a guide rod 341 and a guide sleeve 342. The guide sleeve 342 is fitted over the guide rod 341, and a limit rod 343 is connected between one end of the two guide rods 341. The guide rods 341 and guide sleeve 342 of the guide frame 34 slide against each other, reducing the frictional resistance when the top frame 33 is raised and lowered, and ensuring smooth raising and lowering. The limit rod 343 prevents the guide rods 341 from coming out of the guide sleeve 342, enhancing the structural safety of the guide frame 34, extending the service life of the equipment, and maintaining guiding accuracy. Furthermore, the press-fitting machine 5 includes a press-fitting plate 51, an electric cylinder 52, and a press-fitting head 53. The electric cylinder 52 is fixed to the support frame 2 through the press-fitting plate 51, and the output end of the electric cylinder 52 is fixed to the press-fitting head 53. The pressing machine 5 uses an electric cylinder 52 to drive the pressing head 53. The electric cylinder 52 has high control precision and can accurately adjust the pressing force and pressing stroke to avoid over-pressing or under-pressing of the bushing. The pressing plate 51 fixes the electric cylinder 52 to ensure the stability of the electric cylinder 52 during the pressing process, reduce the impact of vibration on the pressing accuracy, and improve the pressing quality of the bushing.

[0031] Furthermore, the lower two sides of the top frame 6 are connected to abutments 61. The abutments 61 at the bottom of the top frame 6 can limit the movement of the cylinder on both sides, preventing the cylinder from shifting laterally during the pressing process, ensuring the accurate relative position of the cylinder and the pressing head 53, improving pressing consistency, and reducing the scrap rate caused by positioning deviation. Furthermore, the conveyor frame 4 includes drive rollers 41, a first fixed beam 42, and a second fixed beam 43, with several drive rollers 41 connected between the first fixed beam 42 and the second fixed beam 43. The conveyor frame 4 forms a conveying structure through the first fixed beam 42, the second fixed beam 43, and several drive rollers 41. The drive rollers 41 can realize continuous conveying of the cylinder, adapting to the needs of assembly line production and improving the automation level of the equipment; the fixed beams enhance the installation stability of the drive rollers 41, avoiding the impact of structural shaking on the cylinder position accuracy during conveying, and extending the service life of the conveying mechanism.

[0032] The beneficial effects of this utility model are as follows: This utility model adopts a through-type design, realizing the automatic conveying of the cylinder body through the transmission roller 41 of the conveyor frame 4, eliminating the need for manual handling, reducing labor intensity, and improving pressing efficiency. The lifting mechanism 3 is equipped with a guide frame 34. Through the cooperation of the guide rod 341 and the guide sleeve 342, as well as the limiting action of the limiting rod 343, the stability and accuracy of the lifting process of the top frame 33 are ensured, thereby improving the accuracy of cylinder body lifting. The pressing machine 5 uses an electric cylinder 52 to drive the pressing head 53. The electric cylinder 52 has high control precision and can accurately control the pressing force and pressing stroke, ensuring the quality of bushing pressing. The stop 61 at the bottom of the top frame 6 can effectively position the cylinder body, preventing the cylinder body from shifting during the pressing process, further improving the accuracy of pressing.

[0033] Working principle: The cylinder body 7 is conveyed to the pressing position by the transmission roller 41 of the conveyor frame 4. At this time, the lifting cylinder 32 of the lifting mechanism 3 works, driving the top frame 33 to rise. The lifting rod 332 lifts the cylinder body 7, causing it to disengage from the transmission roller 41. Simultaneously, the cylinder body contacts the stop 61 at the bottom of the top frame 6, achieving positioning. Subsequently, the electric cylinder 52 of the pressing machine 5 drives the pressing head 53 to descend, performing the pressing operation on the camshaft bushing of the cylinder body. After pressing is completed, the electric cylinder 52 drives the pressing head 53 to reset, the lifting cylinder 32 drives the top frame 33 to descend, and the cylinder body is placed back on the transmission roller 41, which then conveys the cylinder body to the next process. The workpiece enters the bushing pressing machine 5 from the previous roller conveyor, is lifted to the top frame 6, and simultaneously enters the stop. The electric cylinder 52 begins pressing. After pressing is completed, the workpiece falls onto the roller conveyor and enters the next process. This mainly solves the problem of workpieces not leaving the production line or roller conveyor, reducing scratches and collisions.

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.
