Problems solved by technology

Since the strength of the aluminum casting cover is lower than that of the cast iron and steel casting cover, there is no support in the middle part of the cover when the end face is turned, so the middle part of the end face is prone to indentation during processing, so that the flatness of the end face cannot meet the expected requirements

Embodiment approach

[0042] One end of the flange sleeve 3 with the flange and the seat plate 4 are fixedly installed by bolts. There are two ways of positioning the seat plate 4 and the flange sleeve 3: one is that the side of the seat plate 4 in contact with the flange sleeve 3 is provided with a positioning groove, and the flange sleeve 3 is provided with a groove that passes through the positioning groove. Cooperate with the protrusion for positioning the seat plate 4; the other is that the side of the seat plate 4 in contact with the flange sleeve 3 is provided with a protrusion, and the flange sleeve 3 is provided with a protrusion for positioning the seat plate 4 by cooperating with the protrusion positioning groove. The cooperation mode between the above-mentioned boss and the positioning groove is a transition fit. The other side of the seat plate 4 is fixedly installed with a disc-shaped blocking cover clamping plate 5, and the blocking cover clamping plate 5 completes fastening and pos...

Abstract

The invention discloses a manufacturing method for a cast aluminum type engine blocking cover. The manufacturing method for the cast aluminum type engine blocking cover includes the following steps that firstly, casting is performed, wherein the blocking cover is cast through a metal mold casting method, the bottom face of one side of the blocking cover is a plane, and the other side of the blocking cover is a to-be-machined assembly face; secondly, an end face is turned, wherein the blocking cover is clamped through a turning clamp, the assembly face of the blocking cover is turned, the turning clamp comprises a flange sleeve clamping plate used for ejecting the bottom face of the blocking cover, and a blocking cover top plate used for clamping the assembly face of the blocking cover, and certain machining allowance is reserved for the assembly face of a blank of the blocking cover; and thirdly, hole drilling is performed, wherein the assembly face, machined in the second step, of the blocking cover is placed in a blocking cover installing and clamping device in a whole face attaching manner, the angle and the pressing force of the blocking cover are adjusted by adjusting an angular direction adjusting device and a tight holding force adjusting device, and hole drilling is performed. The invention provides the manufacturing method avoiding sunken deformation of the blocking cover in the end face turning work procedure and thus guaranteeing the planeness of the end face of the blocking cover.

Description

technical field [0001] The invention relates to an engine plug and a manufacturing method, belonging to the technical field of mechanical processing. Background technique [0002] The plugging parts are a kind of key components on the diesel engine, which are used to block various through holes on the diesel engine box, such as the parts assembly access hole on the flywheel housing, the inspection hole on the oil pan, etc. Because its role on the engine is mostly to block the box, it has high requirements on its airtight performance, which is reflected in the manufacturing process of the plug cover, that is, the flatness of its assembly surface is very high. [0003] For the casting process of the prior art, sand casting is usually used, and its production efficiency is low, and the overall property of the sand is soft and porous, so the dimensional accuracy of the castings of sand casting is low, and the surface will be relatively rough. These have a great influence on the...
