Positioning clamp for honing crankshaft hole of automobile connecting rod

Abstract

The invention relates to connecting rod production equipment, in particular to a positioning clamp for honing a crankshaft hole of an automobile connecting rod. The positioning clamp comprises a clampbody, wherein a placing platform is arranged on the clamp body; a placing cushion block for placing the connecting rod is arranged on the placing platform; the placing cushion block is provided witha limiting side plate and a positioning pin; the limiting side plate is used for positioning the side surface of the connecting rod, and attached to the end part of the connecting rod; the positioningpin is connected with a through hole in the connecting rod; and the positioning pin is arranged at one end, away from the limiting side plate, of the placing cushion block. According to the novel positioning clamp for honing the crankshaft hole of the automobile connecting rod, the connecting rod can be quickly positioned and clamped on a machine tool through simple mechanical component combination, so that the honing processing for the crankshaft hole of the connecting rod is fast; and the positioning clamp is simple in structure, low in cost, and suitable for industrial use.

Description

Technical field [0001] The invention relates to connecting rod production equipment, in particular to a positioning clamp used for honing the crankshaft hole of an automobile connecting rod. Background technique [0002] Crank and connecting rod mechanism is one of the two major mechanisms of automobile engines. The function of the automobile engine is to convert the heat energy received on the piston into mechanical energy. Therefore, this mechanism is very important in the engine, especially the connecting rod, in the crank connecting rod mechanism. Both rotation and translation, the force is complicated, and the big end of the connecting rod is the crankshaft hole, which is connected with the crankshaft, and moves frequently in the mechanism, which makes its precision requirements very high, and generally requires honing. [0003] However, the shape of the two ends of the connecting rod is complicated, and the end faces are not in the same plane, which makes the positioning of t...

Problems solved by technology

[0003] However, the shape of the two ends of the connecting rod is complicated, and its end faces are not in the same plane, which makes the positioning of the machine tool honing more troublesome, so the connecting rod is more difficult to locate during honing.
