Abstract

The invention discloses a crankshaft connecting rod neck grinding one hundred and eighty DEG C automatic dividing apparatus. A clamp body (4) is provided with a gear shaft (7) via a pivoting support body, an indexing disc (10) is arranged on the gear shaft (7), two sides of the clamp body (4) are provided with an adjusting pad (12) and an indexing location chock block (9) corresponding to the indexing disc (10), the clamp body (4) is provided with an oil cylinder (13) and a piston (3) thereof which is provided with a rack (2) which meshes with and transmitted with the gear shaft (7). The invention is simple in structure and needs only a simple low pressure hydraulic control loop to control automatic indexing action. The invention can be conveniently connected with a numerical control system and realizes the automatic indexing during neck grinding of the crankshaft connecting rod. The indexing precision can be adjusted via a mechanical turned piece and the adjustment is convenient, stable and reliable. The invention has good maintenance of precision.

Description

technical field [0001] The invention relates to an indexing device, in particular to a 180-degree automatic indexing device for crank pin neck grinding. Background technique [0002] The crankshaft is composed of the main journal and the connecting rod journal. The connecting rod journal is usually distributed eccentrically at a certain angle. For the two-cylinder and four-cylinder crankshafts, the connecting rod journal is distributed at 180 degrees. The traditional crankshaft grinder is divided into two processes when grinding the connecting rod neck, one is directly processed on two machine tools, and the other is processed twice on one machine tool, and manual indexing is required in the middle, which affects Grinding efficiency, indexing accuracy and stability are difficult to guarantee. There are hydraulic and servo automatic indexing fixtures designed abroad, which can realize high-precision automatic indexing, but the price is expensive. Contents of the invention ...
