Background technology
Camshaft is the parts in piston engine, is used to control the opening and closing of valve.The main body of camshaft is a cylindrical barred body approximately uniform with air cylinder group length, and is socketed with several cam bits along the axis direction of barred body, is used for driving valve.In order to meet camshaft requirements of one's work, current camshaft mandrel end is provided with the spline 01 for connecting, in addition it is also necessary to process three rings 02 on camshaft to meet this camshaft job demand under specific circumstances.Wherein, three rings 02 refer to that camshaft is provided with the radial convex loop of an evagination, and this radial convex loop carry out grinding to process three planes, and these three plane constitutes one and offers circulus jaggy, the most inverted П shape structure.That is, in three planarization process of grinding, first camshaft is positioned, then to first plane of radial convex loop grinding, after first plane terminates, drive cam shaft rotates 90 °, again to second plane of radial convex loop grinding, after second plane terminates, drive cam shaft rotates 90 ° again, finally to the 3rd plane of radial convex loop grinding, so process three ring structures.But, in the actual course of processing, after camshaft positions, owing to the precision grasp of each drive cam shaft rotation 90 ° is improper, so three planes that grinding is out can not meet design requirement, thus the job demand of camshaft cannot be met.
Utility model content
The technical problems to be solved in the utility model is, overcomes existing technological deficiency, it is provided that a kind of to processing three high devices for processing off roader cam shaft for diesel engine of ring precision on off roader cam shaft for diesel engine.
Technical solution of the present utility model is, there is provided a kind of device for processing off roader cam shaft for diesel engine with following structure: it includes the grinding machine for processing Camshaft Grinding, grinding machine is provided with for the first thimble of location, camshaft one end and the second thimble for camshaft other end location, second thimble is arranged on slide unit, slide unit is slidably connected on grinding machine, and grinding machine is provided with the power set for driving slide unit to move along camshaft axis direction；Being socketed with rotating disk on first thimble, on rotating disk, the end face towards camshaft is provided with for the projection with the spline clamping on camshaft, and the end face that rotating disk deviates from camshaft is provided with gear, and grinding machine is provided with the motor for driving pinion rotation to rotate to drive rotating disk.
This utility model drives rotating disk to rotate by motor in grinding process, and then drive camshaft turnover, thus by circumferential areas different on cam just to the underface of emery wheel on grinding machine, for grinding machine camshaft carries out grinding, and grinding goes out three planes and forms three rings according to this.Wherein, can accurately control, by the working time controlling motor each, the angle that rotating disk has enough to meet the need every time, then accurately control the angle of cam axle each time so that the angle that camshaft rotates every time is identical, indirectly improve the precision of three rings.Therefore, this utility model provides a kind of to processing three high devices for processing off roader cam shaft for diesel engine of ring precision on off roader cam shaft for diesel engine.
Preferred as one, described power set refer to, grinding machine is provided with cylinder, and the cylinder body of cylinder is fixedly connected on grinding machine, and the expansion link of cylinder is connected with slide unit.Preferred by this, by the movement of air cylinder driven slide unit, and then the second thimble can be driven to move, such that it is able to camshaft is applied an axial force so that camshaft can be positioned on grinding machine.
Preferred as one, described gear is fixedly connected on rotating disk, and geared sleeve is connected on the first thimble.Preferred by this, effectively can be rotated by gear driven rotating disk, and geared sleeve is connected on the first thimble so that the assembling of gear and the first thimble is compacter, and gear can also use the first thimble as mandrel.
Preferred as one, described slide unit is slidably connected on grinding machine by dovetail groove.Preferred by this, slide unit can be guided by dovetail groove so that slide unit slides along the length direction of dovetail groove, it is to avoid slide unit occurs sliding inclined phenomenon in moving process.

Detailed description of the invention
The utility model is described in further detail with detailed description of the invention below in conjunction with the accompanying drawings.
Operation principle of the present utility model: first, by camshaft 1 clamping on grinding machine 2, camshaft 1 right-hand member acts against on the first thimble 3 so that the pointed portion on the first thimble 3 is embedded in the axially extending bore on camshaft 1, and is snapped fit onto by the projection 7 on rotating disk 6 in the spline 01 on camshaft 1；
Then, cylinder 10 drives slide unit 5 to move, the second thimble 4 on slide unit 5 moves closer to camshaft 1, until the pointed portion on the second thimble 4 is embedded into the axially extending bore on camshaft 1 Nei to be clamped in by camshaft 1 in the axial gap between first thimble 3 and the second thimble 4, thus complete the location to camshaft 1；
Subsequently, the stone on grinding machine 2, the periphery on camshaft 1 is carried out grinding, after first flat surface grinding completes, motor 9 works, and drives rotating disk 6 to rotate 90 ° by gear 8；
