Problems solved by technology

However, the flame ring is easy to wear and needs to be replaced regularly. After the engine has been working for a period of time, many carbon deposits will accumulate in the gap between the flame ring and the cylinder liner. It is very difficult to manually remove the flame ring. At present, there is a lack of special tools for easy removal of the flame ring.

Embodiment Construction

[0033] The present invention is described with reference to the drawings and specific embodiments.

[0034] Such as figure 1 , 2 As shown, a combined disassembly tool for an engine piston and a flame ring mainly includes: a support body, a piston tightening device, a flame ring disassembly device, and the like. The support body is composed of a support plate 1 , a handle 4 and a nut 11 . The support plate 1 is disc-shaped, with three fan-shaped weight-reducing holes 14 evenly distributed on it, a boss in the center of the upper end surface, and the center of the boss is a threaded hole, and three holes are evenly distributed on the lower end surface of the support plate 1 along the circumferential direction. T-shaped guide groove 8 and a pair of stepped holes; the handle 4 is U-shaped with a circular cross-section, and the two ends of the handle 4 have a section of thinner external thread, and the two ends pass through a hole on the end surface of the support plate 1 Fix th...

Abstract

The invention belongs to the technical field of machinery and relates to a combination tool and method for installing and detaching an engine piston and a flame ring. The tool comprises a supporting body, a piston tensioning device and a flame ring detaching device, wherein the supporting body is composed of a supporting disc (1), a handle (4) and a nut (11), the piston tensioning device is composed of a tensioning block (9), a spring (10), a push rod (7), a stressing rod (5) and a bolt II, and the flame ring detaching device comprises a positioning block (3) and a bolt I. The combination tool and method solve the problem that the engine piston and the flame ring are hard to detach manually. The combination tool is convenient and fast to operate, labor intensity is low, time and labor are saved, and working efficiency is improved greatly.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a combined disassembly tool and a disassembly method for an engine piston and a flame ring. Background technique [0002] The piston is one of the important moving parts of the engine. It needs to be disassembled regularly to determine whether the piston is abnormal, and the mass of the piston increases with the increase of the cylinder diameter. The mass of many large cylinder diameter pistons is more than 10 kg. Therefore, when disassembling the piston, Firstly, two threaded holes symmetrically distributed along the piston axis should be processed on the top of the piston, and the special tool should be screwed into the two threaded holes for disassembly. [0003] In recent years, as the engine strengthening index has become higher and higher, steel-top aluminum skirt pistons and all-steel pistons have been widely used. Considering the reduction of piston weight and the improve...
