Abstract

The invention discloses a connecting rod big end hole fine boring fixture, which includes a base plate (1), wherein a vertical plate (2) is arranged on the base plate (1); a fixture base (3) is arranged on one side of the vertical plate (2); a stop dog (6) used for positioning a connecting rod and a positioning pin (7) matched with a connecting rod small end hole are arranged on the fixture base (3); a clamping mechanism is also arranged on the fixture base (3), and includes a pressure plate (4); a brace mounting hole is formed near to the middle part of the pressure plate (4); a brace (5) is arranged on the fixture base (3); the brace mounting hole is matched with the brace (5), and enables the pressure plate (4) to swing around the brace (5); one end of the pressure plate (4) is a clamping end, and a jacking mechanism used for jacking the other end is arranged at the other end of the pressure plate (4). Clamping is realized through utilizing the seesaw principle, so that only a screw rod (8), rather than the disassembly of the entire clamping fixture, is needed to rotate for each clamping, as a result, the clamping efficiency is high, and the production efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the field of connecting rod processing equipment, and in particular relates to a precision boring jig for a large end hole of a connecting rod. Background technique [0002] The traditional connecting rod big end hole fine boring fixture adopts the positioning method of setting positioning pins and stoppers on the bottom plate. The clamping mechanism is fastened by bolts. Every time a connecting rod is processed, the fixture needs to be disassembled. The processing efficiency is low and the labor intensity is high. Productivity. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a precision boring fixture for connecting rod big end holes with convenient clamping and high processing efficiency. [0004] In order to solve the above technical problems, the technical solution adopted in the present invention is: a connecting rod big end hole fine boring fixture, including...
