Abstract
The utility model discloses a special fixture of a grinding bar. The special fixture of the grinding bar comprises a fixture body, wherein grinding bar mounting tanks are arranged on the circumference face of the fixture body, magnet mounting tanks communicated with the grinding bar mounting tanks are arranged on the lower parts of the grinding bar mounting tanks, magnets are disposed inside the magnet mounting tanks, and locking disks are fixedly arranged at two ends of the fixture body. The special fixture of the grinding bar is simple in structure, the magnets play a role of radial direction positioning to the grinding bar, the locking disks play a role of axial positioning to the grinding bar, a fixed method which positioning of the magnets and positioning of the locking disks are combined is used for installing and clamping the grinding bar, so that the installing and clamping of the grinding bar are easy and convenient.
Description
Technical field
The utility model belongs to milling tool and uses the clamp technology field, particularly a kind of abrasive stick special fixture.
Background technology
At present, the milled portion of milling tool mainly is an abrasive stick, and abrasive stick is processed by bearing steel matrix and diamond coating, and diamond coating is participated in grinding.Attrition process is a kind of hole polishing processing method; Need on right boring, the basis of finish reaming or finish grinding, carry out, its operation principle is: under certain pressure, abrasive stick contacts with surface of the work; And the relative motion that produces complicacy; Promptly rotatablely move, move back and forth or stressed radial motion, the diamond coating in the motion process on the abrasive stick plays cutting, scraping and squeezing action, downcuts as thin as a wafer smear metal (smear metal mainly is to go up operation at protruding peak that surface of the work stays) from surface of the work.When rotating and moving back and forth between abrasive stick and the workpiece; The diamond coating of abrasive stick cuts layer of material as thin as a wafer from workpiece; The Cutting trajectory of abrasive stick also forms the reticulate pattern that intersects and don't repeat mutually simultaneously; The reticulate pattern cut channel helps storing lubricating oil, makes to form one deck oil film between the piece surface, thereby reduces the surface abrasion between part.The characteristics of abrasive stick attrition process are: 1, because the contact area of abrasive stick and workpiece hole wall cutting speed very big and abrasive stick is lower; The normal load of abrasive particle is merely 1/50-1/100 of grinding, and the cutting speed of abrasive stick generally below 100m/min, is merely 1/30-1/100 of plain grinding; When grinding; A large amount of cutting fluids of injecting can in time wash away the abrasive particle that comes off, and surface of the work is fully cooled off, so workpiece generates heat less, is difficult for burn; And deformation layer is very thin, thereby can obtain higher surface quality; 2, attrition process can reach high dimension precision, form accuracy and lower roughness; Carry out under low speed, low pressure owing to grind; Surface of the work form accuracy and dimensional accuracy high (more than the IT6 level), surface roughness Ra are less than 0.16 μ m; The also corresponding raising of the circularity in hole and cylindricity, and have residual compressive stress and slight work hardening; 3, the time kept in reserve of abrasive stick attrition process is short, production efficiency is high and the range of work is big, and the processing aperture is 15～500mm, and the aspect ratio in hole can reach more than 10.
When processing and reconditioning milling tool, the milling tool that the whole series are used must could guarantee that like this abrasive stick of processing reaches supporting requirements in the production and processing workshop, and operation is extremely inconvenient, wastes time and energy inefficiency.In addition, existing abrasive stick is processed external diameter earlier, is cut inner formation again by bar, and internal material is scrapped, the waste raw material, and processing cost is high, and processing efficient is low.
The utility model content
The utility model provide a kind of simple in structure, clamping is easy and the abrasive stick special fixture of high efficiency.
For realizing above-mentioned purpose; The technical scheme of the utility model is: a kind of abrasive stick special fixture, comprise chuck body, and the periphery of said chuck body is provided with the abrasive stick mounting groove; Be provided with coupled logical magnet mounting groove below the abrasive stick mounting groove, be provided with magnet in the magnet mounting groove; The chuck body two ends are fixed with locking plate.
Be laid with eight abrasive stick mounting grooves that are connected and magnet mounting groove on the periphery of said chuck body.
Be laid with 12 abrasive stick mounting grooves that are connected and magnet mounting groove on the periphery of said chuck body.
Said chuck body one end is provided with the cylinder step.
Said abrasive stick mounting groove is a T shape, and the magnet mounting groove is square.
Compared with prior art, the utility model has the advantages that:
1, the utility model comprises chuck body, and the periphery of said chuck body is provided with the abrasive stick mounting groove, is provided with coupled logical magnet mounting groove below the abrasive stick mounting groove, is provided with magnet in the magnet mounting groove; The chuck body two ends are fixed with locking plate, and it is simple in structure, and magnet plays the radial location effect to abrasive stick, and locking plate plays the axial location effect to abrasive stick, the fixing means clamping abrasive stick that utilizes magnet location and locking plate location to combine, and clamping is easy.
2, be laid with eight abrasive stick mounting grooves that are connected and magnet mounting groove on the periphery of chuck body; Perhaps be laid with 12 abrasive stick mounting grooves that are connected and magnet mounting groove on the periphery of chuck body; Can No. one time eight of clampings or 12 abrasive sticks, can improve the operating efficiency of attrition process greatly.
3, chuck body one end is provided with the cylinder step, is used for linking with lathe, and dismounting is convenient in accurate positioning.
4, the abrasive stick profile of the utility model employing can form through the line cutting processing, and then grinding abrasive stick external diameter, both can save raw material, can improve working (machining) efficiency again.

The specific embodiment
The fixing means clamping abrasive stick 4 that the utility model utilizes magnet 5 location and locking plate 2 location to combine, simple in structure, clamping is easy.
In the utility model when work, connect with lathe and get final product, and easy and simple to handle, specifically coupling method has two kinds: a kind of for to fix to clamp from its two ends with addendum cone, another kind be an end through cylinder step 13 connect with lathe, the other end holds out against with addendum cone.
Be not limited to above-mentioned embodiment; The quantity of the maximum outside diameter of chuck body and abrasive stick mounting groove and magnet mounting groove depends on the circular arc external diameter of abrasive stick 4 and the width of abrasive stick 4 in the utility model; According to customer demand, also can process chuck body with 4 or 16 abrasive stick mounting grooves and magnet mounting groove.
