Description

Grinding wheel for connecting rod of automobile engine

Technical Field

The utility model belongs to the emery wheel field, concretely relates to automobile engine connecting rod grinding emery wheel.

Background

The connecting rod is one of the main transmission components of the automobile engine, and is an important part which connects the piston and the crankshaft, transmits the acting force applied on the piston to the crankshaft and converts the reciprocating motion of the piston into the rotating motion of the crankshaft. The connecting rod group comprises a connecting rod body, a connecting rod big end cover, a connecting rod small end bushing, a connecting rod big end bearing bush, a connecting rod bolt (or screw) and the like. The part connected with the piston pin is called a connecting rod small end; the part connected with the crankshaft is called a connecting rod big head, and the rod part connected with the small head and the big head is called a connecting rod body. The upper plane and the lower plane of the connecting rod big end cover and the connecting rod small end bushing need to be ground. At present, the rough and fine machining of the large head cover and the small head bush of a connecting rod is carried out on the plane by adopting a vertical round platform surface grinding machine and grinding by using a combined sand tile, clamps for grinding two end surfaces are adjacently arranged on a circular workbench of a machine tool, after one end surface is ground, a workpiece is overturned and placed on the other clamp for grinding the other end surface, the workpiece is installed twice and rotates for two circles along with the workbench, so that the two-surface grinding can be completed, and the working efficiency is lower.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an automobile engine connecting rod grinding wheel, through the thickness difference with between other emery wheels that utilize the third emery wheel, can grind the major part and the microcephaly of a plurality of connecting rods simultaneously, improve work efficiency.

The utility model provides a scheme that its technical problem adopted is:

the utility model provides an automobile engine connecting rod grinding wheel, includes the base member, is located one of them terminal surface of base member, is equipped with concentric and for annular first emery wheel, second emery wheel and third emery wheel along its diameter direction from the extroversion inwards in proper order, its characterized in that, the thickness of first emery wheel is the same with the thickness of second emery wheel, and the thickness of third emery wheel is greater than the thickness of first emery wheel and second emery wheel.

By increasing the thickness of the third grinding wheel, when the grinding wheel is used, the third grinding wheel grinds the small end of the connecting rod, the first grinding wheel and the second grinding wheel grind the large end of the connecting rod, and one or more grinding wheels can be simultaneously ground according to the size of the connecting rod.

Further, the clearance between the second grinding wheel and the third grinding wheel is larger than the clearance between the second grinding wheel and the first grinding wheel.

The gaps between two adjacent grinding wheels are different, so that the connecting rod is convenient to clamp, remove chips after grinding and dissipate heat.

Further, the thickness of the third grinding wheel is preferably, but not limited to, 80-100mm, and the thickness of the first and second grinding wheels is preferably, but not limited to, 60-80 mm.

Further, the gap between the second grinding wheel and the third grinding wheel is preferably, but not limited to, 150mm, and the gap between the second grinding wheel and the first grinding wheel is preferably, but not limited to, 30 mm.

Further, the first grinding wheel preferably has a grit size of 54 to 60# and a hardness of G, the second grinding wheel preferably has a grit size of 54 to 60# and a hardness of H, and the third grinding wheel preferably has a grit size of 46 to 54# and a hardness of F.

The utility model has the advantages that:

the large head and the small head of a plurality of connecting rods can be ground simultaneously, the structure is simple, the use is convenient, and the working efficiency is improved.
