Embodiment Construction

[0018] As can be seen from FIG. 1 , a crankshaft turning indexing fixture of the present invention includes left and right eccentricity adjustment mechanisms, left and right clamping mechanisms, indexing mechanisms, positioning mechanisms, and the like. The left and right eccentricity adjustment mechanisms are located at the left and right ends of the fixture. Wherein, the left eccentricity adjustment mechanism mainly includes connecting plate 1, a lead screw 3 installed on the connecting plate 1 through a fixed sleeve 2, a nut 4 matched with the leading screw 3 installed on the fixture base 5, and one end of the connecting plate 1 is installed on the machine tool spindle, The other end is connected with the clamp body or the clamp base 5 through a rectangular track, and the rotating lead screw 3 drives the clamp body or the clamp base 5 to move relative to the connecting plate 1 through the nut 4 to adjust the eccentricity of the crankshaft. The right eccentricity adjustment ...

Abstract

The invention relates to a crankshaft grinding and turning indexing fixture which comprises a left eccentricity regulating mechanism, a right eccentricity regulating mechanism, a left clamping mechanism and a right clamping mechanism; a left fixture body is connected with a fixture base by a bearing; an indexing mechanism and a positioning mechanism are also arranged on the left fixture body; the indexing mechanism is provided with a plurality of conical positioning holes which are distributed on the fixture base, a conical positioning rod installed in a hole of the left fixture body and an operation device thereof and a T-shaped bolt pressing and fixing device; the positioning mechanism comprises a positioning disk installed on the fixture body; positioning pins which are matched with the positioning holes of the end face of a flange of the crankshaft and a positioning pin extending and retracting control device are arranged on the positioning disk. The fixture has reasonable structure, simple, fast and time saving operation, wide indexing range and high production efficiency and is reliable, safe and applicable to the crankshaft grinding and turning indexing fixture for crank phase angle grinding of various crankshafts.

Description

technical field [0001] The invention relates to a crankshaft grinding fixture, in particular to a crankshaft grinding indexing fixture. Background technique [0002] We know that the crankshaft is one of the important parts of the engine that bears impact loads and transmits power. Its structure and force are complex and its work load is large. 120°, 60°, 72°, 90°, 180° or more. And the machining accuracy requirements are very high, and the tolerance is generally required to be ±15'. The existing crankshaft neck grinding fixture used on ordinary crankshaft grinders includes left and right eccentricity adjustment mechanisms, clamping mechanisms, and indexing mechanisms. The eccentricity adjustment mechanism includes a connection plate, a screw mounted on the connection plate through a fixed sleeve, and a nut matched with the lead screw installed on the clamp body. One end of the connection plate is installed on the spindle of the machine tool, and the other end is connected...
