Abstract
The utility model creatively discloses a cartridge grinding rod, has a grinding vessel, it establishes on the plug to grind the barrel casing to nut I through being located both ends is fixed at the plug with nut II, the position of installing the grinding vessel on the plug 1 has 1: 50 the tapering, the interior profile of grinding vessel have with plug assorted tapering. Realize the grinding of high accuracy hole, improve the precision and the efficiency of grinding the hole, reduce the use quantity of ordinary grinding rod, avoid the grinding rod because of the phenomenon of thermal energy with the hole driving fit to existing hole is located to narrow and small position on can be used to grind the aircraft frame.
Description
Technical field
The invention relates to a kind of endoporus milling tool, is specifically related to a kind of cartridge type grinding rod.
Background technology
Grinding rod is the grinding of machining hole on the grinding of the accurate endoporus being widely used in measurer and aircraft.Under normal circumstances, the grinding in a hole needs 4-5 grinding rod, and the material of grinding rod is HT grey cast-iron, and the size difference 0.01mm of each grinding rod diameter, it is more that last excellent lappingout frotton needs.Chip pocket on grinding rod is generally annular straight trough, abrasive pastes in chip pocket and with part contact internal walls, in process of lapping, the easy thermal expansion deformation of grinding rod due to cast iron quality, be closely linked with inner bore of part, not easily take out grinding rod, and be easy to cause aperture openings place to be out of shape when firmly pull grinding rod.
Summary of the invention
The invention is for the deficiencies in the prior art, a kind of cartridge type grinding rod is provided, realize the grinding of high precision inner-pore, improve precision and the efficiency of inner bore grinding, reduce the usage quantity of common grinding rod, avoid grinding rod because of thermal expansion and the closely sealed phenomenon of endoporus, and can be used for the existing endoporus in narrow position place on grinding aircraft ring frames.
The technical scheme that the invention adopts is:
Cartridge type grinding rod, have sand cylinder, described sand cylinder is set on plug, and is fixed on plug by the nut I and nut II being positioned at two ends, the position of described plug being installed sand cylinder has the tapering of 1:50, and the inner mold mask of described sand cylinder has the tapering matched with plug.
Described cartridge type grinding rod, described plug is 9CrSi material plug, and the hardness of described plug is HRC40-45.
Described cartridge type grinding rod, the surface of described sand cylinder is provided with several bidirectional screw shape annular knurl chip pockets, is provided with abrasive pastes in chip pocket.
Described cartridge type grinding rod, the degree of depth of chip pocket is 0.3mm, and the spacing of adjacent chip pocket is 12mm, and the helical angle of chip pocket is 75 degree.
Described cartridge type grinding rod, plug is provided with pin-and-hole, and sand cylinder is provided with the long slot bore corresponding with pin-and-hole position, and one end of pin is inserted in the pin-and-hole of plug through long slot bore, and the other end of pin extends to outside sand cylinder.
Described cartridge type grinding rod, the interior profile of sand cylinder is provided with successively two annular endoporus that internal diameter size increases progressively along the direction that its tapering increases.
The using method of cartridge type grinding rod, after grinding rod uses a period of time, sand cylinder has certain wearing and tearing, screws the sand cylinder on plug by nut II, makes sand cylinder and plug produce deformation to increase the outside dimension of sand cylinder by tensioner.
The using method of described cartridge type grinding rod, also comprises micrometer callipers, the outside dimension after utilizing micrometer callipers to measure sand cylinder tensioner.
The invention has following beneficial effect:
The application of the invention is created cartridge type grinding rod and is ground endoporus, the usage quantity of grinding rod can be reduced, avoid common grinding rod because of thermal expansion and the closely sealed phenomenon of endoporus, improve precision and the efficiency of inner bore grinding, and the existing high precision inner-pore in narrow position place on aircraft ring frames can be ground.

Detailed description of the invention
A kind of cartridge type grinding rod as Figure 1-4, comprise plug 1, nut I 2, sand cylinder 3 and nut II 6, sand cylinder 3 is set on plug 1, and is fixed on plug 1 by the nut I 2 and nut II 6 being positioned at two ends, packing ring 5 is set between nut II 6 and sand cylinder 3, play the effect of fixing sand cylinder 3, described nut I 2 is No. 45 steel, and the hardness of described nut I 2 is HRC33-48.The position of plug 1 being installed sand cylinder has the tapering of 1:50, and the inner mold mask of sand cylinder 3 has the tapering matched with plug 1.This states plug 1 for 9CrSi material plug 1, and the hardness of plug 1 is HRC40-45.The surface of sand cylinder 3 is provided with several bidirectional screw shape annular knurl chip pockets, abrasive pastes are provided with in chip pocket, during grinding, make abrasive pastes have a fixed gap with polished endoporus, effectively prevent grinding rod and processed endoporus due to the situation of the close dead tensioner of abrasive pastes occurs.Preferably, the degree of depth of chip pocket is 0.3mm, and the spacing of adjacent chip pocket is 12mm, and the helical angle of chip pocket is 75 degree.The interior profile of sand cylinder is provided with successively two annular endoporus that internal diameter size increases progressively along the direction that its tapering increases, the size of two annular endoporus is divided into φ=14.5mm, 16mm, effectively reduces the frictional force of sand cylinder 3 and plug 1.Preferably, plug 1 is provided with pin-and-hole, and sand cylinder 3 is provided with the long slot bore corresponding with pin-and-hole position, one end of pin 4 is inserted through long slot bore in the pin-and-hole of plug 1, the other end of pin 4 extends to outside sand cylinder 3, plays the effect of handle, makes not easily to slip out of the hand during the hand-held sand cylinder 3 of operating personnel.
The using method of cartridge type grinding rod, after grinding rod uses a period of time, sand cylinder 3 has certain wearing and tearing, screws the sand cylinder 3 on plug 1 by nut II 6, makes sand cylinder 3 and plug 1 produce deformation to increase the outside dimension of sand cylinder 3 by tensioner.Outside dimension after utilizing micrometer callipers to measure sand cylinder 3 tensioner, just can continue to employ, thus reduces the manufacturing quantity of common grinding rod.
