Description
Technical field
The present invention relates to field of machining, particularly relate to a kind of sanding tool that is used for sand milling cylinder axial workpiece on the lathe.
Background technology
In machine-building such as large-scale marine low speed diesel engine, medium-and-large-sized important spare parts such as Chang Youru diesel engine piston bar, crosshead pin, camshaft, the very high shaft of the precision of cylinder class needs processing on these medium-and-large-sized important spare parts.For example, the shaft required precision of cam shaft for diesel engine and piston rod is high, and rough turn back burr is many, needs polishing, improves precision.
In the middle of the prior art; The process that solves the precision problem of diesel engine cylinder class generally is: after the lathe shaft processed, manual work by on shaft, was pushed down sand paper with wooden stick with sand paper; Rotate machine tool chief axis; Operational danger is very high like this, and the fineness quality behind the sand milling is inhomogeneous, operates also not convenient.
Above-mentioned exists following problem to medium-and-large-sized parts cylinder axial workpiece sander process such as diesel engine piston bars:
1. because the physical dimension of these medium-and-large-sized parts profiles is bigger, and shaft is long, the machine tool specification that therefore is used to process is also bigger, and processing cost is high;
2. because these medium-and-large-sized parts shafts are polished with long wooden stick and sand paper when sanding, and danger is very high, and fineness is also bad, the low staff's of working (machining) efficiency labour intensity is very big.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned prior art, a kind of sanding tool that is used for sand milling cylinder axial workpiece on the lathe is provided, be used for big-and-middle-sized cylinder axis type component precision processing.
Technical solution of the present invention is following:
A kind of sanding tool that is used for sand milling cylinder axial workpiece on the lathe, its characteristics are to be made up of feed drive gearing and sanding head two parts;
Described feed drive gearing works to transmit feeding power and regulates sand milling intensity, comprises sleeve, screw rod and axle plug, and said screw rod places described sleeve respectively with an end of axle plug; And through the contiguous block connection; On the periphery of said axle plug, be provided with straight trough, with the corresponding sleeve of this straight trough on be provided with through hole, in order to limit the effect of described sleeve and axle plug relative position through interior hexagonal straight pin; Can limit feed distance; Can prevent again that simultaneously the axle plug from rotating in sleeve body, the circular arc that the guarantees sanding head part of better fitting is guaranteed the security of operation.
An end that stretches out said sleeve at said axle plug is provided with through hole, and the diameter of this through hole and the diameter of bearing pin are suitable, supply this bearing pin to pass through;
Described sanding head comprises that successively the lamina rara externa, la m and the internal layer felt that connect constitute, and has through hole on the said lamina rara externa, and the diameter of this through hole and the diameter of said bearing pin are suitable, is connected with through hole on the said sleeve in order to pass through this bearing pin and split pin.
Preferably, a side of said la m and internal layer felt is circular arc respectively, is convenient to fit with the cylindrical part outer round surface, has big sand milling area, and cylindrical precision is preferably arranged, and improves part outer round surface fineness effectively.
The outside at said internal layer felt also is provided with pressing plate, in order to fixing internal layer felt.
Described screw rod and axle plug are through said contiguous block matched in clearance, and the free degree that makes screw rod and axle fill in is more flexible, axially with circumferentially more flexible, avoid screw rod to fill in axle and phenomenon in transmission process, occurs killing, improve the life-span of part, and dismounting and change are convenient.
Through the internal layer felt of replacing different-thickness and/or the la m of different arc surfaces, can adapt to the sand milling of the cylinder class piece surface of different-diameter.
Compared with prior art; The invention has the beneficial effects as follows the difficult problem that machining accuracy is low when having solved cylinder Machining of Shaft-type Parts on this large parts lathe, production cost is high and operating personnel's labour intensity is big, processing safety is not high; Reached the requirement of machining accuracy; Have characteristics simple in structure, easy to use, cheap.
