Description

Technical Field

[0001] The utility model belongs to the technical field of crankcase cover processing, and particularly relates to a crankcase cover punching device. Background Art

[0002] The lower part of the cylinder block where the crankshaft is installed is called the crankcase cover. The crankcase cover is divided into an upper crankcase cover and a lower crankcase cover. The upper crankcase cover is cast as one piece with the cylinder block. The lower crankcase cover is used to store lubricating oil and close the upper crankcase cover, so it is also called the oil pan. The oil pan is subjected to very little force and is generally made of thin steel plates. Its shape depends on the overall layout of the engine and the capacity of the engine oil. The oil pan is equipped with an oil stabilizing baffle to prevent excessive fluctuations in the oil level when the motorcycle is shaken. The bottom of the oil pan is also equipped with an oil drain plug, which is usually equipped with a permanent magnet to absorb metal chips in the lubricating oil and reduce engine wear. A gasket is installed between the joint surfaces of the upper and lower crankcase covers to prevent lubricating oil leakage. In the process of producing the engine crankcase cover, some through holes and threaded holes need to be processed on the side or top surface of the crankcase cover. The common method is to use a drill to directly drill or tap. .

[0003] The Chinese patent with application number CN202022200460.2 discloses an engine crankcase punching device, which belongs to the field of crankcase processing technology. It solves the problem that the existing crankcase punching device takes a long time to punch. It includes a bottom plate and a support column arranged on the bottom plate, a top plate is arranged on the support column, a longitudinally telescopic cylinder is arranged on the top plate, a connecting shaft is coaxially fixed to the bottom end of the piston rod on the cylinder, a punching drill driven by a power unit and rotating around the central axis of the connecting shaft is vertically arranged at the bottom end of the connecting shaft, a guide block is arranged on the connecting shaft, a vertically extending guide groove is provided on the guide block, a connecting frame is slidably matched in the guide groove, a pressing plate is arranged at the bottom of the connecting frame, a first elastic member is arranged at the top of the connecting frame, the top of the first elastic member acts on the guide block, and the bottom surface of the pressing plate is lower than the bottom end of the drilling hole under the action of the first elastic member. The utility model first clamps the crankcase and then punches, which reduces the manual operation burden and has high punching efficiency.

[0004] However, when drilling holes on the side of the crankcase cover, the existing skilled workers usually first fix the workpiece to be processed on the vertical plate below the drilling equipment with a clamp, and face the side to be processed to the drill bit, and then start the equipment to drill a through hole in the drilling position. However, since the side of the crankcase cover is an irregular shape, the surface of the ordinary clamp is mostly a regular plane shape, which increases the difficulty of clamping and fixing the crankcase cover, and easily affects the efficiency of product processing. Therefore, an improved crankcase cover drilling device is designed. Utility Model Content
