Problems solved by technology
In the production and processing of the connecting rod, the supporting surface of the connecting rod cap nut should be processed on a milling machine to ensure the flatness of the supporting surface of the connecting rod cap nut. The existing processing fixture can only position one connecting rod cap at a time, and the processing efficiency is low.

The invention discloses a machining clamp for a connecting rod cover nut bearing surface and a clamping method of the machining clamp. The clamp includes a base plate, as well as a connecting rod cover side surface fixing plate, a fastening plate, a fixing plate and a fastening bolt, wherein the connecting rod cover side surface fixing plate and the fixing plate are arranged in parallel and at an interval, and are fixed on the base plate; one end of the fastening bolt penetrates a threaded hole in the middle of the fixing plate, and corresponds to a groove in the middle of the fastening plate; a fixing groove for fixing the two side surfaces of the connecting rod cover is formed between the connecting rod cover side surface fixing plate and the fastening plate. The fastening plate and a jacking bolt of the clamp can be used for simultaneously positioning a group of connecting rod cover arranged side by side, when the connecting rod cover nut bearing surfaces of a plurality of connecting rod covers are machined on a milling machine, only one-time positioning is needed, the machining efficiency is greatly improved, and labor intensity of operators is reduced.
Description
technical field [0001] The invention relates to the technical field of connecting rod processing, in particular to a clamp for processing a supporting surface of a connecting rod cover nut and a clamping method thereof. Background technique [0002] The connecting rod is an important part of the piston engine. The connecting rod includes a connecting rod body and a connecting rod cover, and the connecting rod body and the connecting rod cover are fixed by bolts and nuts. One end surface of the nut is in contact with the nut supporting surface of the connecting rod cover, and the connecting rod cover The flatness of the nut support surface affects the stability of the fixation. In the production and processing of the connecting rod, the supporting surface of the connecting rod cap nut must be processed on a milling machine to ensure the flatness of the supporting surface of the connecting rod cap nut. The existing processing fixture can only position one connecting rod cap a...
