Abstract
The utility model provides a fixture for machining of eccentric bushings. The fixture comprises a connecting disc, a fixed disc, a rotating sleeve, and a central shaft; the fixed disc and the connecting disc are mounted together; the rotating sleeve and the fixed disc are mounted together; the central shaft is mounted in the rotating sleeve; the rotating sleeve is conical; when the rotating sleeve rotates, the distance and angle between the positioning center of the central shaft and a machine tool rotating center is changed. The rotating sleeve rotates relative to the fixed disc; during the cutting process of an index gear on the rotating sleeve, the fixture generates centrifugal force; the rotating sleeve has small offset relative to the fixed disc, so that the centrifugal force generated is small too and the influence upon machining precision is nearly zero; accordingly, the fixture has high precision for machining of the eccentric bushings, workpieces can be reliably clamped and can be machined with one fixture, machining efficiency is high, and machining quality is good.
Description
Technical field
The utility model relates to fixture, more specifically, relates 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.
Utility model content
For above-mentioned defect of the prior art, the utility model provides a kind of fixture for eccentric bushing processing that clamping is reliable, machining accuracy is high.
It is a kind of for processing the fixture of eccentric bushing that the utility model provides, 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 an embodiment of the present utility model, further comprise, one end of described central shaft is provided with the tie rod that described turning set can be strained and fixed.
In an embodiment of the present utility model, further comprise, one end of described tie rod is embedded in the inside of described terminal pad.
In an embodiment of the present utility model, further comprise, also comprise dividing gear, described dividing gear is arranged on described turning set.
In an embodiment of the present utility model, further comprise, described dividing gear is fixed on described turning set by fixing steelframe.
In an embodiment of the present utility model, further comprise, described terminal pad and fixed disk are fixed together by screw.
The utility model has solved deficiency of the prior art, reach following beneficial effect: turning set of the present utility model 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 the eccentric bushing fixture that the utility model provides 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 utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the right view of mechanism of the present utility model.
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 utility model scheme, and above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with embodiment and embodiment accompanying drawing, the utility model is described in further detail.
As shown in Figure 1-2, it is a kind of for processing the fixture of eccentric bushing that the utility model provides, 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 embodiment of the present utility model 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 utility model embodiment, 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 the utility model embodiment, 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 the utility model fixture 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 utility model 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.
