Description
Technical field
The utility model relates to a kind of cylindrical workpiece grinding servicing unit, relates in particular to a kind of cylindrical work grinding frock.
Background technology
In industrial production, often need to be with cylindrical work grinding on grinding machine in order to improve Product Precision and surface roughness.For general precision require or two ends with the cylinder grinding of centre bore, generally can be owing to the unreasonable machining accuracy that makes that is installed is affected, but some products are arranged owing to being subject to the restriction of product Special use requirement, the one or both ends of workpiece do not allow to keep centre bore after through some operation processing, this has just caused difficulty to following process.Namely belong to this kind situation such as the piston in the hydraulic breaking hammer, the design of piston and crudy have determined the performance of quartering hammer dramatically, the impact end of piston and drill steel is not allow centre bore, because stay centre bore may cause piston termination cracking in impact herein.Both required the surface that higher hardness and wearability are arranged for piston, and required again the inner enough toughness that has, this just must adopt some surface Hardening Treatment operations, is exactly the processing mode of commonly using such as carburizing.After surface treatment, also need workpiece is carried out grinding, usually the grinding of this type of workpiece has two kinds of methods: a kind of is that a end at workpiece leaves the process area with centre bore, after all grindings finish, remove again process area, the defective one of this method is owing to needing carburizing and quenching before the grinding work piece, surface of the work hardness improves, therefore after finishing, grinding removes process area just relatively more difficult, and the piston by this processes can increase certain cost owing to destroying process area, the 2nd, the end face that removes behind the process area does not have carburized layer, has therefore affected the hardness of crucial shock surface; Second method is after piston has carried out preceding working procedure processing, impact end at piston is no longer stayed centre bore, like this when entering Carburization Treatment, simultaneously can make the shock surface of piston obtain good surface treatment quality, be very beneficial for improving the performance of piston, but this method stays difficulty in follow-up grinding process being installed of workpiece, and the way of prior art is an end of living workpiece with grinding machine headstock gripper chuck, and the other end that tailstock centre withstands workpiece carries out grinding.Owing to the precision of this kind method that the limits grinding work piece that is subject to grinding machine headstock rotating accuracy is very undesirable, and the adjustment of inconvenient grinding allowance, if the revolution deviation of the warpage of workpiece self and the grinding machine headstock just in time superposes, be easy to products waste, increased manufacturing cost.
The utility model content

Further, also be set with the plug locking nut on the described technique plug.
Adopt the beneficial effect of above-mentioned further scheme to be, the technique plug is considered from recycling, and generally adopts with frock body silk to connect, and therefore needs the plug locking nut, to guarantee machining accuracy.
Further, the edge at the described end also is provided with endless groove.
Adopt the beneficial effect of above-mentioned further scheme to be, endless groove is set is conducive to guarantee cylinder baseplane degree, and the perpendicularity of this plane and axis of workpiece, this is one of leading indicator of this frock.
The using method of the utility model cylindrical work grinding frock is as follows:
1) location of workpiece being adjusted retaining mechanism and technique plug is assembled on the described frock body;
2) tooling sleeve that assembles is contained in an end of workpiece to be processed, the end face of confirming workpiece fits with a baseplane of described frock body;
3) according to the degree of crook of workpiece, adjust retaining mechanism the axis of workpiece and the axis of frock are coincided by adjusting the described location of workpiece, to obtain the grinding allowance of the best, then lock each locking nut, with the fixing all-in-one-piece assembly of workpiece and frock;
4) said modules is fixed on the lathe, levelling is beaten the plug centre bore at described technique plug behind the position;
5) assembly that will accomplish fluently the plug centre bore moves and installs on cylindrical grinder or the grinding machine of universal, namely and tailstock centre grinding machine top with the headstock of grinding machine withstands on respectively on original centre bore of the technique plug centre bore of described assembly and the described workpiece other end, then roughly grinds, fine grinding.
After accomplishing fluently the plug centre bore, also comprise described assembly moved to install on the centre-hole lapping machine plug centre bore is ground.
