Description

Technical Field

[0001] This invention relates to a component pressing machine, specifically to a pressing mechanism for valve seat guides applied to the cylinder head of a diesel engine. Background Technology

[0002] Currently, diesel engines mainly consist of the engine block and cylinder head. The cylinder head contains air passages, oil passages, and water passages, as well as corresponding water passage holes, guide holes (including intake and exhaust guide holes), and seat ring holes. The guide holes and seat ring holes are located on both sides of the cylinder head, respectively. Therefore, it is necessary to install guides (including intake and exhaust guides), seat rings, and other components accordingly. Currently, operators generally place these components manually and use relevant tools to press them into the cylinder head. The quality and accuracy of the pressing are difficult to guarantee uniformity, resulting in low automation and low work efficiency. The bidirectional installation on both sides of the cylinder head also requires a certain amount of labor. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide an automatic pressing mechanism for diesel engine cylinder head seat rings and guides that can automatically press in the seat rings and guides inside the diesel engine cylinder head.

[0004] The objective of this invention is achieved through the following technical solution: an automatic pressing mechanism for diesel engine cylinder head seat ring guides, comprising a base and a bracket, wherein a guide pressing power source and a seat ring pressing power source are respectively mounted on both sides of the bracket, a guide placement assembly that is connected to the guide pressing piston rod of the guide pressing power source and a seat ring placement assembly that is connected to the seat ring pressing piston rod of the seat ring pressing power source are respectively mounted inside the bracket, and a cylinder head running assembly is mounted inside the bracket and between the guide placement assembly and the seat ring placement assembly.

[0005] The catheter placement assembly includes a combination of a catheter slide rail and a catheter baffle, and the seat ring placement assembly includes a combination of a seat ring slide rail and a seat ring baffle. A catheter downward pressure power source is installed on the top of the bracket, above the catheter slide rail, to apply downward pressure to the catheter, flattening and compacting it, so that several overlapping catheters are all at the same level. Both the catheter baffle and the seat ring baffle are provided with observation holes.

[0006] The bracket has corresponding duct channels and seat ring channels located inside and below the duct baffle and seat ring baffle, respectively. The duct slide rails include an intake duct slide rail and an exhaust duct slide rail. The intake duct slide rail has an upper vertical structure and a bottom outward-curving structure, while the exhaust duct slide rail has an overall vertical structure. The duct pressing power source, seat ring pressing power source, duct downward pressing power source, and cylinder head running components are all electrically connected to a microcomputer controller for unified and precise control.

[0007] With the structure of this invention, several overlapping guide tubes are placed inside the guide tube slide rail and fitted with guide tube baffles. Similarly, several overlapping seat rings are placed inside the seat ring slide rail and fitted with seat ring baffles. A guide tube pressing power source drives a guide tube pressing piston rod, automatically pressing the bottommost guide tube through the guide tube channel into the guide tube hole of the cylinder head workpiece. Likewise, a seat ring pressing power source drives a seat ring pressing piston rod, automatically pressing the bottommost seat ring through the seat ring channel into the seat ring hole of the cylinder head workpiece. This invention ensures good and accurate guide tube and seat ring pressing, reduces labor intensity, enables simultaneous bidirectional installation on both sides of the cylinder head workpiece, has a high degree of automation and high work efficiency, and guarantees the quality of the cylinder head product.

[0014] Reference Figures 1 to 4 As can be seen, the present invention applies to the automatic pressing mechanism for diesel engine cylinder head seat ring guides in diesel engine production, including a base 1 (lower position) and a bracket 10 (upper position). On both sides of the bracket 10, there are several guide pressing power sources 3 (guide pressing cylinders, arranged horizontally) and several seat ring pressing power sources 9 (seat ring pressing cylinders, arranged horizontally). Inside the bracket 10, there are several guide placement assemblies 7 (corresponding groups) that are connected to the guide pressing piston rod 2 of the guide pressing power source 3, and several seat ring placement assemblies 6 (corresponding groups) that are connected to the seat ring pressing piston rod 12 of the seat ring pressing power source 9. Inside the bracket 10 and between the guide placement assembly 7 and the seat ring placement assembly 6, there is a cylinder head running assembly 8 (which drives the cylinder head workpiece to run on a slide rail via a chain).

[0015] like Figure 2 , Figure 3 , Figure 5 As shown, the catheter placement assembly 7 includes a combination of a catheter slide rail 11 and a catheter baffle 13, and the seat ring placement assembly 6 includes a combination of a seat ring slide rail 15 and a seat ring baffle 16. Figure 1 , Figure 4 As shown, since the conduits are long and narrow, manual placement cannot guarantee their horizontal descent. A downward pressure is needed to flatten and compact them, ensuring that several overlapping conduits are at the same level. A conduit pressing power source 5 (a conduit pressing cylinder, several in number, with its pressing piston rod aligned with the conduits placed inside the conduit slide rail) is installed on the top of the support 10 and above the conduit slide rail 11. The conduit baffle 13 and seat ring baffle 16 are each equipped with baffle observation holes 18 (several arranged longitudinally at intervals). Some conduits and seat rings are positioned precisely within these observation holes to observe whether their placement orientation is correct. The conduit pressing power source 3, seat ring pressing power source 9, conduit pressing power source 5, and cylinder head running assembly 8 are all electrically connected to a microcomputer controller 4 (including a touchscreen) for unified and precise control.

[0016] Inside the bracket 10, and below the guide tube baffle 13 and the seat ring baffle 16, there are respectively a guide tube channel 19 (which connects to the guide tube pressing piston rod of the guide tube pressing power source) and a seat ring channel 20 (which connects to the seat ring pressing piston rod of the seat ring pressing power source). Figure 5 As shown, the duct slide rail 11 includes an intake duct slide rail 21 (for placing the intake duct, with the bottom placed at an angle) and an exhaust duct slide rail 22 (for placing the exhaust duct). The intake duct slide rail 21 has an upper vertical structure and a bottom angled outward bending structure (the two are combined). The exhaust duct slide rail 22 has an overall vertical structure.

[0017] The working principle of this invention is as follows: The bottom of the guide rail 11 and the seat ring rail 15 are both equipped with push holes corresponding to the guide channel 19 and the seat ring channel 20, respectively, for the guide to press into the piston rod 2 and the seat ring to press into the piston rod 12. Several vertically overlapping guides 14 are placed in the guide rail 11 (pressed downward by the guide downward pressing power source 5) and a guide baffle 13 is installed, with the two bottom guides protruding outside the guide baffle. Several vertically overlapping seat rings 17 are placed in the seat ring rail 15 and a seat ring baffle 16 is installed, with the two bottom seat rings protruding outside the seat ring baffle. Then, the cylinder head workpiece 23 reaches the position between the guide baffle 13 and the seat ring baffle 16 during the sliding transport of the cylinder head running assembly 8. When the guide hole and seat ring hole of the cylinder head workpiece are respectively aligned with the positions of the guide channel 19 and the seat ring channel 20 of the bracket, the cylinder head running assembly 8 stops running. Next, the guide pipe pressing power source 3 operates, driving the guide pipe pressing piston rod 2 into the discharge hole at the bottom of the guide pipe slide rail 11. This automatically presses the bottommost guide pipe through the guide pipe channel 19 into the guide pipe hole of the cylinder head workpiece. Simultaneously, the seat ring pressing power source 9 operates, driving the seat ring pressing piston rod 12 into the discharge hole at the bottom of the seat ring slide rail 15. This automatically presses the bottommost seat ring through the seat ring channel 20 into the seat ring hole of the cylinder head workpiece. Finally, the guide pipe pressing piston rod 2 and the seat ring pressing piston rod 12 return to their original positions. The second-to-last guide pipe and seat ring fall to the bottom, and the cylinder head running assembly 8 outputs the pressed-in cylinder head workpiece. This process is repeated in a cycle.
