Description

Piston ring trimming and milling machine

technical field

The utility model relates to a milling machine, in particular to a piston ring repairing milling machine.

Background technique

The piston ring is an important part of the piston of the automobile and motorcycle engine. It seals the cylinder together with the piston, prevents the high-pressure gas from leaking downward from the upper part of the piston, and transfers the heat of the piston to the cylinder wall, so that it has a good heat dissipation effect; at the same time, Piston rings control the thickness of the lubricating oil film on the cylinder walls, scrape excess lubricating oil back into the tank, and prevent lubricating oil from entering the combustion chamber. The piston ring rubs against the cylinder wall when the piston moves up and down, and is worn to protect the piston from contact with the cylinder wall. With the development of the automobile industry, the requirements for the quality and output of engine piston rings are getting higher and higher. The previous piston ring processing equipment can no longer meet the requirements of modern processing. Therefore, new, high-speed, high-efficiency piston ring special equipment has been developed. It is imperative.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

Fig. 1 is a front view of a piston ring repairing milling machine, Fig. 2 is a left view of a piston ring repairing milling machine, Fig. 3 is a front view of a milling cutter milling a piston ring opening, and Fig. 4 is a top view of a milling cutter milling a piston ring opening, as As shown in the figure. The piston ring trimming milling machine includes a bed 1, a motor-driven bevel gear reducer set on the bed 1, a power head 2, a trimming die 3 with a horn structure, a storage device 4, a feeding device 5, and a pressing device 6. Collecting device 7 and milling cutter 8. The milling cutter 8 is installed on the power head 2 and driven by the power head 2 to rotate.

Wherein, the feeding device 5 includes a crank linkage mechanism composed of a disc I9, a connecting rod I10 and a V-shaped push block 11 for sending the piston ring to be processed into the trimming die 3 . The disc I9 is used as the crank of the crank linkage mechanism and is driven by the power output shaft I of the bevel gear reducer. One end of the connecting rod I10 is hinged on the disc I9, and the other end is hinged on the V-shaped push block 11. The V-shaped push block 11 Set on the cover plate 12 of the bed 1 and slidingly fit with the cover plate 12, the V-shaped push block 11 is located under the material storage device 4, and the sliding track of the V-shaped push block 11 is from the bottom of the material storage device 4 to the trimming die catchy this distance.

The pressing device 6 includes a vertically arranged linear guide rail I, and a crank linkage II composed of a disc II13, a connecting rod II14 and a pusher rod 15 that pushes the piston ring out from the trimming die 3 .
