Abstract
The utility model provides an inequality profile modeling device for a cam grinder, which at least comprises an inequality profile modeling part and a guide wheel; the inequality profile modeling part consists of a base circle part and a curve part, wherein the shape of the inequality profile modeling part is the same as that of a cam, and the radius of the base circle of the inequality profile modeling device is small than that of the base circle of the cam; the guide wheel is in close contact with the inequality profile modeling part in the rotary machining process; the axis line of the guide wheel is parallel to that of the inequality profile modeling part; a workpiece and the inequality profile modeling part are closely fastened and are kept coaxial; and the radius of the base circle of the inequality profile modeling part is 0.30+/0.02mm smaller than that of the base circle of the cam. The inequality profile modeling device for the cam grinder, provided by the utility model, is sample in structure, easy to manufacture and convenient to install and use; and the workpiece can be clamped on the inequality profile modeling device in one step, a grinding process can be finished in the high-speed cam grinder, and the machining precision of parts is high.
Description
Technical field
The utility model relates to a kind of cam mill inequality copying apparatus, belongs to the Machining Technology field.
Background technology
Camshaft is an important components in the engine driving system, and the grinding of camshaft adopts following mode to realize usually:
One. adopt the no profile copy grinding machine tooling of total control, need investment to introduce the CBN grinding machine and the emery wheel of import, this method is high to operator's specification requirement, and input cost is big, and the machine upkeep cost is higher.
Two. adopt centerless grinder and novel no pattern CNC cam grainder; With centerless grinder cam is roughly ground, with novel no pattern CNC cam grainder cam is finish grinded, this method is high to operator's specification requirement at present; Input cost is big; Clamping times and operation are more than 2 times, and input cost is bigger, and processing cost is high.
Summary of the invention
The purpose of the utility model is to provide a kind of cam simple in structure mill inequality copying apparatus; Adopt this device can on the High speed cam grinding machine, accomplish cam journal corase grind operation man-hour adding; Thereby control the dimensional accuracy of its cam contour profile and workpiece, improve correct grinding efficient.
The technical scheme that realizes the utility model purpose is: a kind of cam mill inequality copying apparatus comprises inequality pattern spare and guide wheel at least; Inequality pattern spare is made up of base circle portion and curved portion, and the profile of inequality pattern spare is identical with cam, and the base radius of inequality pattern spare is littler than the base radius of cam; Guide wheel closely contacts in rotary processing with inequality pattern spare; Guide wheel axial line and inequality pattern spare axis parallel; Workpiece is fastening and keep coaxial with inequality pattern spare.
And the base radius of inequality pattern spare is littler 0.3 ± 0.02 millimeter than the base radius of cam.
Can know that by technique scheme that workpiece and inequality pattern spare keep is coaxial, with rotating speed and equidirectional in rotary processing, and the base radius of inequality pattern spare is littler 0.3 ± 0.02 millimeter than the base radius of cam; Guide wheel closely contacts with each point of inequality pattern spare outline in rotary processing, and the movement locus of inequality pattern spare outline is delivered on the emery wheel of grinding machine.Can on the High speed cam grinding machine, realize the mill manufacturing procedure of camshaft by this device.
The utility model compared with prior art has the following advantages and beneficial effect:
1. this device can be used for the High speed cam grinding machine, can realize camshaft processing of a great variety, that batch is big, has less investment, low, the advantage of high production efficiency of processing cost.
2. simple in structure, easy to manufacture, the installation and easy to use of cam mill inequality copying apparatus that provides of the utility model.
3. workpiece clamping once on this device can be accomplished grinding process on the High speed cam grinding machine, and part processing precision is high.
Description of drawings:
The cam mill inequality copying apparatus sketch map that Fig. 1 provides for the utility model.
Among the figure: 1, guide wheel, 2, inequality pattern spare, 3, workpiece, 4, emery wheel, 5, tailstock centre, 6, the headstock.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1, the cam mill inequality copying apparatus that the utility model provides comprises inequality pattern spare 2 and guide wheel 1; Inequality pattern spare 2 is made up of base circle portion and curved portion, and the profile of inequality pattern spare 2 is identical with cam, and the base radius of inequality pattern spare 2 is littler 0.3 ± 0.02 millimeter than the base radius of cam; Guide wheel 1 closely contacts in rotary processing with inequality pattern spare 2; Guide wheel 1 axial line and inequality pattern spare 2 axis parallels; Workpiece 3 and inequality pattern spare 2 are fastening and keep coaxial.
In the processing, workpiece 3 is fastening with the headstock 6, and tailstock centre 5 top tight workpieces, guide wheel 1 are installed on the High speed cam grinding machine; In rotary processing inequality pattern spare 2 and guide wheel 1 near, guide wheel 1 can roll on axle; When inequality pattern spare 2 rotates, force through the headstock 6 to be fastened on tailstock and to treat 3 one swing of grinder part, 4 pairs of workpiece of emery wheel 3 carry out grinding, thereby workpiece 3 is formed and the consistent profiles of inequality pattern spare 2 profiles.
