Background technology
Spot-facing is a kind of mechanical processing technique of reprocessing the original hole on workpiece, and its form scrapes planar end surface, cuts out taper chamfering, cylindrical pit etc.In some thin plate porous ramming parts, because punching precision does not reach, the position degree in each hole and size are all difficult to meet design requirement, and when therefore carrying out spot-facing chamfering to this kind of part, difficulty is larger.Existingly be rigid knife bar for the knife bar connected between drilling machine and spot-facing cutter, that is: under any circumstance its axial location is immutable for the rotation of the rotation of drilling machine and knife bar, cutter.Carry out spot-facing chamfering with so rigid knife bar to the original hole on sheet workpiece, often occur that chamfering is eccentric, even one side of something does not go out phenomenon, seriously has influence on outward appearance and the process quality of product.Therefore, rigid knife bar is not suitable with the spot-facing chamfer machining of thin plate porous ramming part.
Summary of the invention
The bias occurred when carrying out spot-facing chamfering for existing rigid knife bar to thin plate porous ramming part, one side of something do not go out phenomenon, and the utility model provides a kind of spot-facer floating cutter arbor.
The utility model Bian gets following technical scheme and implements: a kind of spot-facer floating cutter arbor, be made up of outer Mohs connecting taper shank, cross shaft joint, bearing pin, stop collar, resilient bushing, interior Mohs branch sleeve, jump ring, elastic washer, the top of described outer Mohs connecting taper shank is Mohs cone, bottom is cylinder, and Mohs cone is connected with the interior mohs tapered bore in drilling machine main shaft; Described interior Mohs branch sleeve top is cylinder, and bottom is changable sleeve, and the outer Morse taper shank on itself and spot-facer is connected, and it is characterized in that:
The cylindrical end face of described outer Mohs connecting taper shank bottom is provided with rectangular channel recessed in the axial direction, and two sides and the axial center section of rectangular channel are symmetrical parallel;
The end face of described interior Mohs branch sleeve upper cylinder is provided with rectangular channel recessed in the axial direction, and two sides and the axial center section of rectangular channel are symmetrical parallel;
The key that described cross shaft joint one end is provided with is inserted in the rectangular channel of outer Mohs connecting taper shank, and the key that the other end is provided with is inserted in the rectangular channel of interior Mohs branch sleeve, and forms two hinges respectively by bearing pin;
The internal face of described stop collar is provided with to entering the recessed annular space in body direction, described resilient bushing is inserted in annular space, form the endoporus elasticity wall of stop collar, on the cylinder external diameter of its overcoat Mohs connecting taper shank bottom outside, on the external diameter of cross shaft joint, on the cylinder external diameter on interior Mohs branch sleeve top, and form matched in clearance;
Jump-ring slot is provided with between the Mohs cone on described outer Mohs connecting taper shank top and the cylinder of bottom, described jump ring is fastened in jump-ring slot, described elastic washer is arranged on the cylinder on interior Mohs branch sleeve top and between changable sleeve step surface and the lower surface of stop collar, jump ring and elastic washer limit the axial location of stop collar jointly.
The utility model is by the mutual vertical hinge at cross shaft joint two ends, and pass through the elasticity wall of stop collar endoporus, in common formation Mohs branch sleeve relative to outer Mohs connecting taper shank in radial directions can floating structure, thus be the spot-facing chamfering of thin plate porous ramming part, provide centering condition, not only increase processing quality, and increase work efficiency.
The utility model has reasonable in design, that structure is simple, easy to operate, crudy is good advantage.
Accompanying drawing explanation
Accompanying drawing 1 is main sectional structure schematic diagram of the present utility model;
Accompanying drawing 2 is left sectional structure schematic diagram of the present utility model.
In attached Fig. 1 and 2: Mohs branch sleeve in 1 outer Mohs connecting taper shank, 2 jump rings, 3 stop collars, 4 elastic washers, 5,6 and 6 ' bearing pin, 7 resilient bushings, 8 cross shaft joints.
Detailed description of the invention
Below in conjunction with accompanying drawing, explanation is further explained to the utility model:
As shown in accompanying drawing 1,2, outer Mohs connecting taper shank 1 is connected with the interior mohs tapered bore in drilling machine main shaft; Interior Mohs branch sleeve 5 is connected with the outer Morse taper shank on spot-facer; The Mohs cone bottom of outer Mohs connecting taper shank 1 is cylinder, and cylindrical lower surface is provided with rectangular channel recessed in the axial direction, and two sides and the axial center section of rectangular channel are symmetrical parallel; Be cylinder in the middle part of cross shaft joint 8, two ends are square key, and two square keys are mutually vertical, and the two rectangle keyboards of every one end are all symmetrical parallel with axial center section; The external diameter of interior Mohs branch sleeve 5 is provided with two sections of cylinders, and wherein the cylindrical end face of epimere is provided with rectangular channel recessed in the axial direction, and two sides and the axial center section of rectangular channel are symmetrical parallel; Its one end of square key at cross shaft joint 8 two ends is inserted in the rectangular channel on outer Mohs connecting taper shank 1, and the other end is inserted in the rectangular channel on interior Mohs branch sleeve 5, and forms the fixed hinge at cross shaft joint 8 two ends respectively by bearing pin 6 and bearing pin 6 '; The internal face of stop collar 3 is provided with to entering the recessed annular space in body direction; Resilient bushing 7 is inserted in annular space, form the endoporus elasticity wall of stop collar 3, on cylinder external diameter on the cylinder external diameter of its overcoat Mohs connecting taper shank 1 bottom outside, in the middle part of cross shaft joint 8, on the cylinder external diameter on interior Mohs branch sleeve 5 top, and form matched in clearance; Be provided with jump-ring slot between the Mohs cone on outer Mohs connecting taper shank 1 top and the cylinder of bottom, jump ring 2 is fastened in jump-ring slot; Elastic washer 4 is arranged between step upper surface between interior Mohs branch sleeve 5 two sections of cylinders and the lower surface of stop collar 3, and jump ring 2 and elastic washer 4 limit the axial location of stop collar 3 jointly.
In the process of spot-facing chamfering, when spot-facer not with hole coaxial and monolateral cutting time, its monolateral cutting force can force cross shaft joint 8 around bearing pin 6 ' instantaneously, interior Mohs branch sleeve 5 is done slightly to rotate around bearing pin 6 simultaneously, make between cross shaft joint 8 and outer Mohs connecting taper shank 1, between interior Mohs branch sleeve 5 and cross shaft joint 8, the disalignment state of trace is formed in the elasticity wall of stop collar 3 endoporus, and universal change is constantly done on 360 ° of rotation rounds, with the axis that centering has been holed, thus be the spot-facing chamfering of thin plate porous ramming part, provide centering condition.
The utility model is by the mutual vertical hinge at cross shaft joint two ends, and by the elasticity wall of stop collar endoporus, common form in Mohs branch sleeve relative to outer Mohs connecting taper shank in radial directions can floating connecting structure, not only increase processing quality, and increase work efficiency.
