Preferably, also connecting axle is provided with between described pull bar and described tapered sleeve.
Preferably, the distance between the axis of described overcoat and the axis of described inner sleeve is less than or equal to 3mm.
Preferably, the end face of described inner sleeve is also provided with straight pin.
Preferably, with bolts between described overcoat and described inner sleeve.
Preferably, the number of described bolt is two.
Relative to above-mentioned background technology, the fixture that the utility model provides, comprise the overcoat of Morse taper shank and one end interference fit with Morse taper shank, the clamping end face of overcoat is provided with inner sleeve, the circle centre position of the end face of inner sleeve is provided with and can expands or shrink in order to realize clamping or to loosen the spring bushing of part to be processed, the inside of Morse taper shank is provided with the pull bar that one end is connected with the piston rod of lathe, the other end of pull bar be positioned at spring bushing inside, the tapered sleeve that spring bushing expands or shrinks can be made along with moving of pull bar, lathe tool can be made to treat distance that processing parts processes off-centre operation or eccentric orfice is provided with between the axis of overcoat and the axis of inner sleeve.Adopt this setup, utilize the inner sleeve being arranged on the clamping end face of overcoat to fix part to be processed, due to the axis of overcoat and the axis not conllinear of inner sleeve, between two axis, tool is provided with distance; This distance can make to overlap outside drive inner sleeve and in put part revolution to be processed time, lathe tool can be treated processing parts and process off-centre operation or eccentric orfice; That is, we can determine between the axis of overcoat and the axis of inner sleeve according to the distance in required off-centre operation or the center of circle of eccentric orfice and the center of circle of part to be processed distance; So, lathe tool just can be made on part to be processed to process off-centre operation or eccentric orfice, thus achieve the object of processing off-centre operation or eccentric orfice easily.
Accompanying drawing explanation
Fig. 1 is the structural representation of fixture provided by the utility model and part to be processed.
Detailed description of the invention
Core of the present utility model is to provide a kind of fixture, and this fixture can turning eccentric orfice easily.
In order to make those skilled in the art understand the utility model scheme better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Please refer to Fig. 1; Fig. 1 is the structural representation of fixture provided by the utility model and part to be processed.
The fixture that the utility model provides, comprise the overcoat 3 of Morse taper shank 2 and one end interference fit with Morse taper shank 2, the clamping end face of overcoat 3 is provided with inner sleeve 4, the circle centre position of the end face of inner sleeve 4 is provided with and can expands or shrink in order to realize clamping or to loosen the spring bushing 5 of part 9 to be processed, the inside of Morse taper shank 2 is provided with the pull bar 1 that one end is connected with the piston rod of lathe, the other end of pull bar 1 is with to be positioned at spring bushing 5 inner, the tapered sleeve 7 that can spring bushing 5 be made to expand along with moving of pull bar 1 or shrink, lathe tool can be made to treat distance that processing parts 9 processes off-centre operation or eccentric orfice is provided with between the axis of overcoat 3 and the axis of inner sleeve 4.
Adopt this setup, utilize the inner sleeve 4 being arranged on the clamping end face of overcoat 3 to fix part 9 to be processed, due to the axis of overcoat 3 and the axis not conllinear of inner sleeve 4, between two axis, tool is provided with distance; This distance can make when overcoat 3 drives the part to be processed 9 in inner sleeve 4 and inner sleeve 4 to turn round, and lathe tool can be treated processing parts 9 and process off-centre operation or eccentric orfice; That is, we can determine between the axis of overcoat 3 and the axis of inner sleeve 4 according to the distance in required off-centre operation or the center of circle of eccentric orfice and the center of circle of part to be processed 9 distance; So, lathe tool just can be made on part 9 to be processed to process off-centre operation or eccentric orfice, thus achieve the object of processing off-centre operation or eccentric orfice easily.
Certainly, we can be provided with connecting axle 6 between pull bar 1 and tapered sleeve 7.That is, connecting axle 6 is utilized to be connected with tapered sleeve 7 by pull bar 1; Certainly, we can be provided with external screw thread at connecting axle 6, in pull bar 1 with tapered sleeve 7, arrange internal thread, thus pull bar 1 and tapered sleeve 7 are connected on connecting axle 6, realize the object that pull bar 1 is connected with tapered sleeve 7.
Certainly, for connecting axle 6, one end of connecting axle 6 is concentric with the main shaft of lathe, and the other end is concentric with tapered sleeve 7, so just can realize the object of processing off-centre operation or eccentric orfice.
In addition, the distance between the axis of overcoat 3 and the axis of inner sleeve 4 can be less than or equal to 3mm by us.
Specifically, if the distance in the center of circle of the center of circle of required off-centre operation or eccentric orfice and part to be processed 9 is 1mm, namely the eccentric throw of part 9 to be processed is 1mm, then the distance between the axis of overcoat 3 and the axis of inner sleeve 4 can be set to 1mm; Similar, if the distance in the center of circle of the center of circle of required off-centre operation or eccentric orfice and part to be processed 9 is comparatively large, the distance between the axis of overcoat 3 and the axis of inner sleeve 4 just can be set to 3mm by us; Certainly, according to actual conditions, the distance between the axis of overcoat 3 and the axis of inner sleeve 4 can also be set to other distances by us, will repeat no more herein.
In addition, we can also be provided with straight pin 8 at the end face of inner sleeve 4.That is, we can utilize straight pin 8 to fix part 9 to be processed; Certainly, the position of straight pin 8 can set according to different parts to be processed 9, repeats no more herein.
In addition, the diameter of straight pin 8 can also be set to the diameter of the locating hole being less than part 9 to be processed by us.
So, straight pin 8 just can inject in the locating hole of part 9 to be processed by we, thus the object that processing parts 9 positions is treated in realization.Certainly, the number of straight pin 8 can be set to two by us.So, utilize two straight pins 8 effectively can treat processing parts 9 and position, thus realize turnery processing off-centre operation or eccentric orfice.
In addition, can be with bolts between overcoat 3 and inner sleeve 4.That is, bolt is utilized to be fixed on the clamping end face of overcoat 3 by inner sleeve 4; Certainly, overcoat 3 and inner sleeve 4 can be set to interference fits by us.
In addition, the number of the bolt between overcoat 3 and inner sleeve 4 can be set to two.That is, by two bolts, overcoat 3 and inner sleeve 4 are fixed, be so just conducive to dismounting when changing.Certainly, we can also arrange the bolt of other numbers, will repeat no more herein.
Above fixture provided by the utility model is described in detail.Apply specific case herein to set forth embodiment of the present utility model, the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping.Should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle, can also carry out some improvement and modification to the utility model, these improve and modify and also fall in the protection domain of the utility model claim.
