Abstract
The invention relates to the machining field, in particular to a hexagonal mandrel machining method. The hexagonal mandrel machining method comprises the steps of turning a step shaft with the length greater than the required length for work-pieces firstly, wherein the sizes of steps at the two ends are the same, center holes are drilled in the two ends and circles are ground; carrying out equal division through an indexing head with the circles at the two ends as the standard, milling six surfaces, guaranteeing hexagonal equal division, machining the work-pieces, preserving the machining allowance of 0.5 mm and carrying out heat treatment after machining is completed; polishing center holes after the heat treatment; grinding the conical degree, preparing two copper sheets of 0.05 mm, placing one copper sheet on a grinding machine platform, pressing one end of a hexagonal shaft at one end of a steel sheet, placing the other end of the hexagonal shaft on the grinding machine platform, forming the height difference of 0.05 mm at the two ends of the hexagonal shaft, carrying out surface grinding on the three adjacent surfaces and guaranteeing that the size of the small ends, the size of the middle parts and the size of the three opposite sides are equal; stacking the two copper sheets and placing the two copper sheets on the grinding machine platform. According to the invention, the machining process is simple, manufacturing is easy, the machining quality and the dimensional accuracy of the work-pieces can be guaranteed, the production efficiency can be improved, and the production cost can be lowered.
Description
Technical field
The present invention relates to field of machining, be specifically related to six side's axle processing methods.
Background technology
Hexagonal hole sprocket wheel uses widely in machinery industry, but need use six side axle when detecting the beating of hexagonal hole sprocket wheel, and six side's axle make time, relative both sides symmetry should be ensured and beat, ensure the tapering of six side's axles again, adopt common processing methods, success rate is very low, and crudy and the dimensional accuracy of workpiece can not be ensured, even cause waste product.
Summary of the invention
In order to solve the problem, the invention provides a kind of process simple, be easy to manufacture, and ensure crudy and the dimensional accuracy of workpiece, enhance productivity, reduce by six side's axle processing methods of production cost.
The present invention six side axle processing method, comprises the following steps:
The first step, blanking, first turning length is greater than the Step Shaft of workpiece requirement, and two ends step dimension is identical, two ends drill centers, then grinds platform circle, ensures coaxial with centre bore, clamping and location when processing in order to postorder;
Second step, with two end stand circles for benchmark, dividing head decile, milling six, ensures six side's deciles, processing work, and stays allowance to be 0.5mm, after machining, heat-treats, and adopts high-frequency quenching;
3rd step, advanced study and training centre hole after heat treatment, cylindrical grinder grinds two ends fowl circle and sees light, ensure that two circles are coaxial with centre bore, on plain grinding grinding machine, grinding six side axle one meets personally light, stay appropriate surplus, the face crossed by plain grinding is adsorbed on the workbench of surface grinding machine, the height of two end stand circles is detected with the lever meter on height gauge, ensure that two ends height is consistent, if highly inconsistent, can by padded method adjustment height, can adjust with the copper sheet of the clearance gauge scrapped or respective thickness, like this with two end stand circles for benchmark, grinding six successively, ensure to two end stand circle common axis symmetry and beat qualified,
4th step, grinding core degree, the copper sheet of standby two 0.05mm, is placed on grinding machine platform by a copper sheet, be pressed on sheetmetal by six square shaft one end, one end is placed on grinding machine platform, two ends height of formation difference 0.05mm, adjacent three of plain grinding, ensure small end size, intermediate sizes, three opposite side sizes are equal; Two copper sheets are stacked in one piece to be placed on grinding machine platform, and be pressed in six square shaft one end on two copper sheets, one end is placed on grinding machine platform, and mill residue three, just ensure that the tapering needed for six side's axles, ensure that small end size simultaneously;
Process of the present invention is simple, is easy to manufacture, and ensures crudy and the dimensional accuracy of workpiece, enhances productivity, reduces production cost.
Detailed description of the invention
The present invention six side axle processing method, comprises the following steps:
