Abstract

The invention discloses a combined tool for dismounting an engine oil seal, which comprises a handheld part, an impact part and a dismounting part, the handheld part comprises a handle and an impact sliding sleeve, the impact part is arranged on the right end surface of the handle, the impact part comprises a connecting rod, an impact block and a protective sleeve, the connecting rod is provided with the impact block and the protective sleeve, and the impact sliding sleeve is arranged on the impact block. The surface of the right side of the connecting rod is provided with threads, the right end face of the connecting rod is provided with a dismounting part, the dismounting part comprises a fixing rod, a dismounting head, a bolt and a nut, the right end face of the fixing rod is provided with a rectangular notch, the dismounting head is arranged in the rectangular notch, the end face of the dismounting head is conical, and the side wall of the dismounting head is provided with an annular groove. Coaxial penetrating through holes are formed in the side wall of the fixing rod and the side wall of the dismounting head, and a bolt penetrates through the penetrating through holes of the fixing rod and the dismounting head and is tightened through a nut. The method has the advantages that the parts are not damaged, secondary use of the parts is facilitated, and the cost for purchasing the parts is reduced.

Description

【Technical field】 [0001] The invention belongs to the technical field of engine maintenance equipment, and particularly relates to a combined tool for disassembling an engine oil seal and a method for using the same. 【Background technique】 [0002] Oil seal, also known as shaft seal, is a device part used in machines to prevent fluid (mostly lubricating oil) from overflowing from joints (mostly joint surfaces or shafts of parts). [0003] In the process of engine overhaul, it takes time for the overhaul engineer to overhaul the oil seal of the engine. Usually, the drill rod structure such as screwdriver, crowbar and other tools are used to pry the oil seal. Because the internal structure of the oil seal has a stereotyped iron shell, commonly known as the iron frame, The prying method needs to insert a screwdriver into the contact surface before the camshaft and the oil seal, and then use the lever principle to pry out the oil seal. During this process, the oil seal is subjec...
