Abstract
The invention relates to a lathe tailstock hole grinding fixture. The fixture comprises a core shaft (1); a tapered guide sleeve (2) is arranged in the middle of the core shaft (1); a taper sleeve (3) is arranged on the guide sleeve (2); the taper sleeve (3) consists of three taper sleeve blocks; a grinding spiral groove (4) is formed on the surface of each of the three taper sleeve blocks, a spring mounting groove (6) is formed on each of the front and rear sides of each grinding spiral groove (4), a spring (5) is arranged in each spring mounting groove (6), and the three taper sleeve blocks are fixed through the springs (5); a washer (9) and an adjusting nut (10) are arranged at each of the front end and the rear end of the taper sleeve (3); and grinding sand (7) is arranged on the surface of the taper sleeve (3). The lathe tailstock hole grinding fixture is simple in structure and convenient to operate, can be used for lathes of the same model, is low in manufacturing cost and high in grinding efficiency, and can effectively ensure the precision control of surface roughness, roundness, cylindricity and the like of a lathe tailstock hole.
Description
Technical field
The present invention relates to a kind of precision and grind special tooling, be mainly used in the precision attrition process is carried out in engine lathe tailstock hole, belong to gold and cut equipment precision service technique field.
Background technology
Grind in the repairing in engine lathe tailstock hole precision, traditional mode is that grinding rod is made in preparation according to tailstock hole dimension list.And the characteristics that precision is ground are that size constantly increases, and surface roughness constantly reduces.Change along with tailstock hole dimension after grinding, need again prepare grinding rod, will realize that simultaneously surface roughness reduces, need progressively to use higher order to count abrasive sand, even this has just determined to prepare many grinding rods, also be difficult to satisfy fully the size of process of lapping, the instant change of precision.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, a kind of tail stock hole grinding tool is provided, it is simple in structure, makes Meteorological few, and grinding efficiency is high, and effectively the guarantee fund cuts the control of machine tool accuracy repairing quality.
The object of the present invention is achieved like this: a kind of tail stock hole grinding tool, it comprises mandrel, described mandrel middle part is provided with a fairlead that is tapering, be provided with tapered sleeve on the described fairlead, described tapered sleeve is made of three tapered sleeve pieces, described three tapered sleeve piece surfaces are provided with the grinding helicla flute, both sides are provided with the spring fitting groove before and after the described grinding helicla flute, in the described spring fitting groove spring is installed, described three tapered sleeve pieces fix by spring, described tapered sleeve front-end and back-end are provided with packing ring and adjusting nut, and described tapered sleeve closely cooperates by packing ring and adjusting nut and fairlead, and described tapered sleeve surface is provided with abrasive sand.
Described mandrel front end is provided with handle.
Compared with prior art, the present invention has following beneficial effect:
A kind of tail stock of the present invention hole grinding tool, it is simple in structure, and is easy to operate, the homotype lathe is as long as a cover frock, the making Meteorological is less, and grinding efficiency is high, can effectively guarantee the precision controls such as tail stock hole surface roughness, circularity and cylindricity.

The specific embodiment
Referring to Fig. 1, a kind of tail stock of the present invention hole grinding tool, it comprises mandrel 1, described mandrel 1 middle part is provided with a fairlead 2 that is tapering, be provided with tapered sleeve 3 on the described fairlead 2, described tapered sleeve 3 is made of three tapered sleeve pieces, described three tapered sleeve piece surfaces are provided with grinds helicla flute 4, both sides, described grinding helicla flute 4 front and back are provided with spring fitting groove 6, in the described spring fitting groove 6 spring 5 is installed, described three tapered sleeve pieces fix by spring 5, described tapered sleeve 3 front-end and back-end are provided with packing ring 9 and adjusting nut 10, and described tapered sleeve 3 closely cooperates with fairlead 2 by packing ring 9 and adjusting nut 10, and described tapered sleeve 3 surfaces are provided with abrasive sand 7, described abrasive sand 7 closely cooperates with tapered sleeve 3 by grinding helicla flute 4, and described mandrel 1 front end is provided with handle 11.
During grinding, press the hole dimension of tail stock 8 and regulate adjusting nut 10, choose larger order and count abrasive sand 7 and grind; After grinding certain hour, by hole dimension, the surface roughness of the tail stock 8 after grinding, regulate once again adjusting nut 10, choose less order and count abrasive sand 7 and again grind.Go round and begin again, to repairing till tailstock hole cylindricity, surface roughness reach standard-required.Three large I of tapered sleeve piece abradant surface external diameter are by carrying out balanced change with the taper fit shift in position of fairlead.
Claims (2)
1. tail stock hole grinding tool, it is characterized in that: it comprises mandrel (1), described mandrel (1) middle part is provided with a fairlead (2) that is tapering, be provided with tapered sleeve (3) on the described fairlead (2), described tapered sleeve (3) is made of three tapered sleeve pieces, described three tapered sleeve piece surfaces are provided with grinds helicla flute (4), both sides are provided with spring fitting groove (6) before and after the described grinding helicla flute (4), spring (5) is installed in the described spring fitting groove (6), described three tapered sleeve pieces fix by spring (5), described tapered sleeve (3) front-end and back-end are provided with packing ring (9) and adjusting nut (10), described tapered sleeve (3) closely cooperates with fairlead (2) by packing ring (9) and adjusting nut (10), and described tapered sleeve (3) surface is provided with abrasive sand (7).
