Abstract

The invention provides a fixture for machining eccentric sleeves. The fixture comprises a connecting plate, a fixed plate, a rotary sleeve and a center shaft; the fixed plate and the connecting plate are mounted together, the rotary sleeve and the fixed plate are mounted together, and the center shaft is mounted in the rotary sleeve which is tapered; distance and angle between the center of location of the center shaft and the center of rotation of a machine tool are changed along with rotation of the rotary sleeve. The rotary sleeve can rotate relative to the fixed plate, the fixture can generate a centrifugal force during cutting of a dividing gear on the rotary sleeve, but the centrifugal force is small due to small offset of the rotary sleeve relative to the fixed plate and nearly no influence is caused to the machining precision; therefore, the fixture for machining the eccentric sleeves has high machining precision, can clamp workpieces reliably and complete machining of the eccentric sleeves all by itself, and is high in machining efficiency and good in machining quality.

Description

A kind of for processing the fixture of eccentric bushing
Technical field
The present invention relates to fixture, more specifically, relate to a kind of for processing the fixture of eccentric bushing.
Background technology
Eccentric bushing is a kind of adjustable part of diameter of bore of realizing, add screw can reach inner ring circumferentially, the object of axial restraint, be widely used in as in the machineries such as planet-cycloid reducer, be also a part conventional in textile industry machinery.
In the processing of textile machinery part, can there is the processing problems of eccentric bushing, the fixture of processing eccentric bushing will meet the eccentric bushing cylindrical that completes turning axis parallel (bias) in a procedure.In batch production, there are some problems in eccentric bushing fixture, for example, makes clamping workpiece unreliable, and need to assist a plurality of fixtures to use, and the clamping time is long, reduces working (machining) efficiency, and can not effectively guarantee the quality of the part of processing.
Summary of the invention
For above-mentioned defect of the prior art, the invention provides a kind of fixture for eccentric bushing processing that clamping is reliable, machining accuracy is high.
The invention provides a kind of for processing the fixture of eccentric bushing, the fixed disk that comprises terminal pad, is installed together with described terminal pad, the turning set being installed together with described fixed disk and be arranged on the central shaft in described turning set, described turning set is the turning set of taper, and described turning set changes the centre of location of described central shaft and distance and the angle of lathe pivot while rotating.
In one embodiment of the present of invention, further comprise, one end of described central shaft is provided with the tie rod that described turning set can be strained and fixed.
In one embodiment of the present of invention, further comprise, one end of described tie rod is embedded in the inside of described terminal pad.
In one embodiment of the present of invention, further comprise, also comprise dividing gear, described dividing gear is arranged on described turning set.
In one embodiment of the present of invention, further comprise, described dividing gear is fixed on described turning set by fixing steelframe.
In one embodiment of the present of invention, further comprise, described terminal pad and fixed disk are fixed together by screw.
The invention solves deficiency of the prior art, reach following beneficial effect: turning set of the present invention rotates relative to fixed disk, in dividing gear working angles on turning set, fixture can produce centrifugal force, because the side-play amount of the relative fixed disk of turning set is less, so the centrifugal force producing is also less, almost nil on machining accuracy impact, therefore, the precision of eccentric bushing fixture provided by the invention when processing eccentric bushing is higher, reliable to clamping workpiece, a fixture can complete the processing of eccentric bushing, and working (machining) efficiency is high and crudy good.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the right view of mechanism of the present invention.
Wherein, 1-central shaft, 11-tie rod, 2-turning set, 3-fixed disk, 4-terminal pad, 5-dividing gear, 6-is steelframe fixedly, 7-mark location 1,8-mark anchor point 2.
The specific embodiment
In order to make those skilled in the art person understand better the present invention program, and above-mentioned purpose of the present invention, feature and advantage can be become apparent more, below in conjunction with embodiment and embodiment accompanying drawing, the present invention is further detailed explanation.
As shown in Figure 1-2, the invention provides a kind of for processing the fixture of eccentric bushing, mainly comprise terminal pad 4, fixed disk 3, turning set 2, central shaft 1, above-mentioned fixed disk 3 is installed together with above-mentioned terminal pad, above-mentioned turning set 2 is installed together with above-mentioned fixed disk 3, and above-mentioned central shaft 1 is arranged in above-mentioned turning set 2.Above-mentioned turning set 2 changes the centre of location of above-mentioned central shaft 1 and distance and the angle of lathe pivot while rotating, in order to make turning set 2 can better change distance and the angle of central shaft 1 centre of location and lathe pivot, the turning set 2 in embodiments of the invention is the turning set 2 of taper.
Wherein, in one end of above-mentioned central shaft 1, be provided with the tie rod 11 that above-mentioned turning set 2 can be strained and fixed, the effect of this tie rod 11 is to be strained and fixed to being set in the turning set 2 of central shaft 1 excircle, and one end of above-mentioned tie rod is embedded in the inside of above-mentioned terminal pad.On above-mentioned turning set 2, be provided with dividing gear 5, the precision of these dividing gear 5 positioning centres is higher, and dividing gear 5 is fixed on above-mentioned turning set 2 by fixing steelframe; Above-mentioned terminal pad 4 and fixed disk 3 are fixed together by screw.
In the embodiment of the present invention, the central shaft 1 of fixture can coordinate very accurately with workpiece, wherein, and the mounting center of axle 1 centered by O in Fig. 1, O 1the center of rotation of turning set 2, O 2it is the pivot of lathe.The center of rotation O of the mounting center O of central shaft 1 and turning set 2 1keep certain distance, turning set 2 can change central shaft 1 mounting center O and be decided to be center and lathe pivot O 2distance and angle.When stirring turning set 2, by the dividing gear 5 on turning set 2, make turning set 2 on the position of 0 ° or 180 ° during (7,8 gauge points in Fig. 2) location, two pivots that guaranteed two eccentric bushings respectively with the pivot O of lathe 2overlap; By 11 pairs of turning sets 2 of tie rod, be strained and fixed again, can carry out the cylinder turning of two ends, eccentric bushing left and right.
In fixture in embodiments of the present invention, turning set 2 rotates relative to fixed disk 3, and the dividing gear 5 on turning set 2 is in working angles, and fixture can naturally produce certain centrifugal force.The side-play amount of the turning set 2 relative fixed disks 3 in fixture of the present invention is less, and the centrifugal force of generation is also less, and almost nil on machining accuracy impact, therefore, the machining accuracy of the eccentric bushing of fixture production and processing of the present invention is higher.But if in actual production, when the eccentricity value of processing work is larger, balance in addition, to reduce the impact of centrifugal force on machining accuracy.
The above; be only the specific embodiment of the present invention, protection scope of the present invention is not limited to this, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claim was defined.
