Description

A kind of ball ring-shaped work pieces grinding attachment
Technical field:
The utility model relates to grinding attachment technical fields, and in particular to a kind of ball ring-shaped work pieces grinding attachment.
Background technique:
Interior ball ring-shaped work pieces is part less common in the field of machining, therefore many small-sized machine processing factories Often do not have the interior ball shape equipment for grinding of profession, thus can not the Precision Machining part.It is past even if having made simple tooling by oneself Toward because can only be used for specific grinding wheel, it can not be repeated as many times and use, also be not suitable for the grinding wheel of different size.For precision Part, the requirement to grinding wheel spherical surface is high, needs constantly to be modified grinding wheel spherical radius in grinding process, and accurate amendment is difficult Degree is big, and correction effect is unstable, if therefore replacing entire grinding wheel, cost is again high.
Utility model content:
The purpose of this utility model is to overcome above-mentioned the shortcomings of the prior art places, and provide a kind of ball shape Part grinding attachment, it is cheap, and production is simple, easy to use, can repeatedly utilize, adapt to the ball ring-shaped work pieces of plurality of specifications Grinding attachment.
The technical solution adopted in the utility model are as follows: a kind of ball ring-shaped work pieces grinding attachment, including shaft, expansion pawl, cone Shape set, spheric washer, round nut and ball grinding wheel, both ends of the shaft are respectively equipped with center hole, are equipped with the shaft shoulder, the shaft shoulder one in shaft Side is equipped with expansion pawl, expansion pawl and shaft using interference fit connection, and expansion pawl is equipped with internal taper, and expansion pawl is opposite with the shaft shoulder Side be equipped with taper sheath, taper sheath is gap-matched with shaft and connect, and taper sheath is equipped with external taper, external taper and internal taper Taper is identical, and described shaft one end is equipped with screw thread, and the round nut is covered on screw thread, is equipped between round nut and taper sheath Spheric washer;It expands and ball grinding wheel is installed outside pawl.
The expansion pawl is the thin metal parts of annular opening that one end has uniformly distributed gap.
The spheric washer is made of a pair of concave-convex gasket.
The beneficial effects of the utility model are: this ball ring-shaped work pieces grinding attachment, can repeatedly use;By replacing not The ball grinding wheel of same specification is, it can be achieved that the ball machine parts'precise to sizes is ground;It is convenient for disassembly and assembly;It is easy to make, it is at low cost It is honest and clean;By adjusting round nut, it is convenient to replace grinding wheel;It is low in cost using ball grinding wheel, and the present apparatus replaces grinding wheel side Just, the grinding wheel of accurate grinding is unable to for having worn out, it is not necessary to which reconditioning is directly replaced.
Detailed description of the invention:
Fig. 1 is the utility model section view;
Fig. 2 is the utility model expansion pawl structure chart.
Specific embodiment:
Referring to each figure, a kind of ball ring-shaped work pieces grinding attachment, including shaft 1, expansion pawl 2, taper sheath 3, spheric washer 4, Round nut 5 and ball grinding wheel 6,1 both ends of shaft are respectively equipped with center hole, and 1 is equipped with the shaft shoulder in shaft, and shaft shoulder side is equipped with expansion Pawl 2, expansion pawl 2 and shaft 1 using interference fit connection, expansion pawl 2 be equipped with internal taper, expansion pawl 2 it is opposite with the shaft shoulder one Side is equipped with taper sheath 3, and taper sheath 3 is gap-matched with shaft 1 and connect, and taper sheath 3 is equipped with external taper, external taper and internal taper Taper is identical, described 1 one end of shaft be equipped with screw thread, described 5 sets of round nut on screw thread, between round nut 5 and taper sheath 3 Equipped with spheric washer 4;It expands and ball grinding wheel 6 is installed outside pawl 2.The expansion pawl 2 is that there is the annular in uniformly distributed gap to open for one end 7 thin metal parts of mouth.The spheric washer 4 is made of a pair of concave-convex gasket.
Referring to Fig.1, there is a center hole at the both ends of shaft 1, one end be used to mounted in slewing it is top on, the other end can press from both sides It holds, using interference fit connection, expansion pawl 2 carries out axially position by the shaft shoulder of shaft 1 for shaft 1 and expansion pawl 2;Taper sheath 3 It is gap-matched with shaft 1;There is screw thread in one end of shaft 1, and round nut 5 is on screw thread;Spheric washer 4 is mounted in taper sheath 3 Between round nut 5.
Referring to Fig. 2, expansion pawl is the thin metal parts of annular opening 7 that an one end has uniformly distributed gap, main function It is by swelling ball grinding wheel 6 after radial force;Taper sheath 3 is a metal parts with taper identical as expansion 2 inner hole of pawl; Its main function is to be provided radial force by after axial thrust for expansion pawl 2;The taper of taper sheath 3 and expansion 2 inner hole of pawl is big In self-locking angle, when taper sheath 3 is by axial force, it will lead to expansion pawl 2 and be radially expanded.Spheric washer 4 is by two concave-convex pads Circle is composed, can automatic adjusting position, make with the taper sheath of shaft clearance fit by more uniform axial force, and With stopping function, main function is to transmit axial force for taper sheath 3, simultaneously because it has retaining effect, thus anti-rotation stop Round nut 5 loosens when axis high speed rotation, and due to the ability that it has automatic adjusting position by oneself, makes and turns, the cone of 1 clearance fit Shape set 3 is by more uniform axial force, to preferably guarantee the concentricity of ball grinding wheel 6 and shaft 1;Round nut 5 is one A screw thread specification metal parts identical with 1 screw thread of shaft, main function are axial force to be provided for taper sheath 3 and unloading is axial Power conveniently realizes the disassembling, assembling and replacing of ball grinding wheel 6.
Ball grinding wheel 6, the radial pressure that ball grinding wheel 6 is implemented it after expanding by expansion pawl 2 can be installed outside expansion pawl 2 Power, to generate frictional force, the two links together.
In use, round nut 5 is unscrewed out, since the mating surface taper of taper sheath 3 and expansion pawl 2 is greater than self-locking angle, And taper sheath 3 and shaft 1 are clearance fit, and taper sheath 3 will be skidded off outward (or with outside threaded tool screw-in taper sheath 3 The threaded hole of end face, pulls out), then it expands pawl 2 and loses the external force being radially expanded, it will radial contraction, at this time by ball Then 6 inner hole of grinding wheel screws round nut 5 on expansion 2 outer diameter of pawl, in this way, circle spiral shell, 5 push spheric washer 4, spheric washer 4 Push taper sheath 3,3 pairs of expansion pawls 2 of taper sheath apply radial forces, expansion pawl 2 be radially expanded to 6 swelling of ball grinding wheel, by The grinding mesh of internal ball ring-shaped work pieces can be realized on the common rotating machinery process equipments such as lathe or grinding machine in the device 's.
In conclusion this ball ring-shaped work pieces grinding attachment, can repeatedly use;By the ball sand for replacing different size Wheel 6 is, it can be achieved that the ball machine parts'precise to sizes is ground;It is convenient for disassembly and assembly;It is easy to make, it is low in cost;Justified by adjusting Nut 5, it is convenient to replace grinding wheel;It is low in cost using ball grinding wheel 6, and present apparatus replacement grinding wheel is convenient, for having ground Damage is unable to the grinding wheel of accurate grinding, it is not necessary to which reconditioning is directly replaced.
