[0002] At present, there is no special positioning tool for the boring process of automobile connecting rods. The positioning of automobile connecting rods is carried out through the combination of several positioning structures, and the positioning fasteners need to be tightened manually. The positioning accuracy is poor, which affects the processing quality of the big head hole of the connecting rod.

The invention discloses a connecting rod large-head end machining positioning device. The device comprises a baseplate, and a positioning support plate vertically arranged on the baseplate. The connecting rod large-head end machining positioning device further comprises a hydraulic cylinder, a pushing cylinder, and a pressing plate for pressing a large-head end of a connecting rod; a connecting rod small-head positioning column is arranged on the side, near a boring cutter, of the positioning support plate; the pressing plate is movably arranged on the positioning support plate through a pin shaft; the upper end of the pressing plate is arranged corresponding to the large-head end of the connecting rod; the hydraulic cylinder is provided with an ejector rod for ejecting the lower end of the pressing plate; the positioning support plate is provided with a positioning stopper for limiting one side of the large-head end of the connecting rod; the pushing cylinder is arranged on the positioning support plate; and the pushing cylinder is provided with a positioning block for positioning the other side of the large-head end of the connecting rod. A small-head hole of the connecting rod sleeves the connecting rod small-head positioning column during positioning; the large-head end of the connecting rod is pressed through the pressing plate; positioning structures are arranged on two sides of the large-head end of the connecting rod to achieve high positioning precision; and three-point limited positioning is reliable, so that the connecting rod cannot move during machining, and the machining precision is further improved.
Description
technical field [0001] The invention relates to the technical field of connecting rod processing, in particular to a processing and positioning device for the big end of a connecting rod. Background technique [0002] At present, there is no special positioning tool for the boring process of automobile connecting rods. The positioning of automobile connecting rods is performed by combining several positioning structures. The positioning fasteners need to be tightened manually, and the positioning accuracy is poor, which affects the processing quality of the big head hole of the connecting rod. Contents of the invention [0003] Aiming at the deficiencies of the existing technology, the technical problem to be solved by the present invention is to provide a processing and positioning device for the big end of the connecting rod, so as to achieve the purpose of high positioning accuracy. [0004] In order to solve the problems of the technologies described above, the technic...
