Abstract
The utility model provides a combined grinder used to process stepped bores. The grinder comprises a grinding rod (1) and a plurality of grinding bushes (2) with different inner diameters; wherein, the grinding rod is made of metal; and the grinding bushes are made of non-metallic material. One end of the grinding rod (1) is provided with a cylindrical held end (a) which can be clamped on a lathe chuck; a plurality of stepped conical supporting ends (b) sized down are formed from the middle section to the front end of the grinding rod (1); and the length of the stepped cone depends on the depth of the inner bore of the part to be processed. The grinding bushes (2) with different inner diameters are respectively assembled on the corresponding stepped conical parts of the supporting ends of the grinding rod (1), the grinding bush for processing is a main grinding bush, the grinding bush of the other section is an auxiliary grinding bush, and the main and the auxiliary grinding bushes can be exchanged for use. When being used, the grinder provided by the utility model can process a bore with different inner diameters at a time, the coaxiality can meet the requirement, and thereby, high efficiency and high precision can be realized.
Description
Technical field
The present invention's invention relates to a kind of field of machining, the using method of the particularly mill of processing parts endoporus, and this mill.
Background technology
Mill is a kind of common machine finishing instrument, and it is widely used in fields such as Aeronautics and Astronautics, particularly the machining high-precision endoporus.Present mill all is used for the processing of single endoporus, need add man-hour running into the stepped hole that has axiality to require, usually can only adopt the replacing mill, the hole that is different inner diameters uses different mills to process one by one, Jia Gong part like this, though the shape and size in single hole can meet the demands, the axiality between each hole is difficult to guarantee, therefore the qualification rate of product is lower, influences quality.
Summary of the invention
The purpose of this invention is to provide a kind of multiple grinding device that is used for processing step hole, and the using method of this mill, use mill provided by the invention, can guarantee the hole of time processing different inner diameters, axiality meets the demands, and accomplishes high efficiency, high accuracy.
Mill of the present invention comprises: the milling bar (1) and several different grinding sleeves of being made by nonmetallic materials (2) of internal diameter made by metal material.Milling bar (1) one end is columniform bare terminal end (a), be used for clamping at machine chuck, milling bar (1) interlude to front end is several different step-like cone support ends (b) from large to small, and the length of its step cone is looked the difference of hole depth in its part that need process and difference.Grinding sleeve (2) is the annulus of opening vertically, and endoporus is a tapered hole, is placed in during use on the milling bar (1).
The using method of mill of the present invention is:
A. with milling bar (1) clamping of mill on machine chuck;
B. the grinding sleeve (2) with different inner diameters is loaded on respectively on the corresponding step cone position of milling bar (1) support end, at this moment, the grinding sleeve that is used to process is main grinding sleeve, and the grinding sleeve of other section is the assisted milling cover, and main and auxiliary grinding sleeve can be changed use mutually;
To firmly it be knocked in the cone of milling bar when C. installing and support the position, end, make its opening part spreading, hold milling bar support end as the main grinding sleeve of processing usefulness;
Firmly be not locked when D. assisted milling cover is installed, its effect is part to be played the assist location effect at main grinding sleeve during to part processing;
E. after an endoporus machines, the grinding sleeve of its processing is struck pine, make it become the assisted milling cover and be used for the location, another grinding sleeve that will need again to process loads, and makes it become main grinding sleeve and carries out processing grinding.
Use mill processing of the present invention to have the step hole shape part of different inner diameters, the axiality of processed stepped hole is reached in the Φ 0.004mm, and can also play the effect of rectification to the bad part of axiality.The structure and the processing method of apparatus of the present invention are simple, the product processed stable performance.

The specific embodiment
Utilize multiple grinding device of the present invention to be processed with two inner bore of step parts, as shown in Figure 3.
At first, select for use one to have the milling bar 1 of two sections taperings and two sections big grinding sleeve 3 and little grinding sleeves 4 of supporting that the end external diameter matches of internal diameter and milling bar;
With milling bar 1 clamping to the scroll chuck of lathe;
Respectively big grinding sleeve 3 and little grinding sleeve 4 are loaded on the milling bar 1, earlier with big grinding sleeve 3 as the assisted milling cover, processing parts is played the role of positioning, when being loaded on little grinding sleeve 4 on the milling bar 1, to firmly it be knocked in milling bar 1 and support the cone of end, the opening spreading of little grinding sleeve 4 is tightly blocked, make it, part is processed as main grinding sleeve;
After machining, the large and small grinding sleeve of clamping allows little grinding sleeve 4 unclamp as assisted milling and overlaps its positioning action again, make big grinding sleeve 3 become main grinding sleeve part processed, until with part processing till meet the demands.
Claims (4)
1, a kind of multiple grinding device, comprise the grinding sleeve (2) that milling bar (1) is different with several internal diameters, it is characterized in that: an end of milling bar (1) is cylindrical bare terminal end a, milling bar (1) interlude to front end is several different step-like cone support end b from large to small, and the grinding sleeve of different inner diameters (2) is placed in respectively on each support end b of milling bar (1).
2, multiple grinding device according to claim 1 is characterized in that: grinding sleeve (2) is opening vertically, and endoporus is a tapered hole.
