Abstract
The utility model relates to an internal gear eccentric sleeve excircle processing clamp which comprises a clamp body, a transition disc, a first fastening piece, a mandrel, a second fastening piece and balancing weight blocks. The transition disc is arranged at one end of the clamp body, and is fixedly connected with the clamp body through the transition disc. The mandrel is fixed at the other end of the clamp body, the second fastening piece is connected with the clamp and is arranged above the mandrel, and two balancing weights are arranged on the second fastening piece. The internal gear eccentric sleeve excircle processing clamp can maintain balance when rotating along the mandrel, reduce centrifugal force generated by rotation along with the mandrel when a workpiece is processed, eliminate possible radical runout generated by the workpiece when the workpiece processes an excircle, ensure accuracy of processing of the excircle, and is convenient and safe to operate, high in processing efficiency, and suitable for batch processing.
Description
Technical field
The utility model relates to a kind of fixture, relates in particular to a kind of fixture for machining interal eccentric bushing cylindrical, belongs to the Workpiece clamping device technical field of machining.
Background technology
The internal gear eccentric bushing is a kind of part that is used for supporting internal gear, its structure as shown in Figure 1, because gear requires engagement accurately, make in engagement process wearing and tearing little, so guarantee that the eccentric throw of eccentric bushing and inside and outside circle diameter are the keys that guarantees the gear correct engagement.Existing traditional diamond-making technique is that at first the roughing cylindrical, then process endoporus take cylindrical as benchmark with after fixture clamping internal gear eccentric bushing, at last fine finishining cylindrical again.Although the internal gear eccentric bushing can be processed like this, but a lot of defectives are arranged, because respectively there is a crescent at the two ends, left and right of this eccentric bushing one side, so can produce centrifugal force with the revolution of main shaft adding the man-hour workpiece, make workpiece bowlder outside fine finishining may produce circular runout, thereby the crudy of workpiece, the life-span of cutter and operator's safety are impacted, cause the working (machining) efficiency of workpiece low, the precision of cylindrical can't be guaranteed, and the requirement of batch machining can not be satisfied.
The utility model content
The utility model purpose is that a kind of internal gear eccentric bushing Excircle machining fixture that can guarantee the Excircle machining precision and improve working (machining) efficiency is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of internal gear eccentric bushing Excircle machining fixture comprises clamp body, transition disc, the first securing member, axle, the second securing member and balancing weight; Described clamp body one end is provided with transition disc; Described transition disc and clamp body are fixedly linked by the first securing member; The described clamp body other end is fixed with axle; Described the second securing member is connected with clamp body and is positioned at the top of axle; Described the second securing member is provided with two balancing weights.
Preferably, it is characterized in that: also be provided with packing ring on described the second securing member.
Preferably, described the second securing member is screw.
Preferably, the quantity of described the first securing member is six.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Internal gear eccentric bushing Excircle machining fixture of the present utility model, can keep balance in the main shaft rotation, reduce to add the man-hour workpiece and produced centrifugal force with the revolution of main shaft, eliminated the issuable circular runout of workpiece bowlder outside fine finishining, guaranteed the Excircle machining precision.Internal gear eccentric bushing Excircle machining fixture of the present utility model, easy and safe to operate, working (machining) efficiency is high, is applicable to batch machining.
Description of drawings
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of internal gear eccentric bushing;
Accompanying drawing 2 is the structural representation of internal gear eccentric bushing cylindrical of the present utility model;
Accompanying drawing 3 is the front view that internal gear eccentric bushing Excircle machining fixture of the present utility model uses state;
Wherein: 1, clamp body; 2, transition disc; 3, the first securing member; 4, axle; 5, the second securing member; 6, balancing weight; 7, packing ring; 8, internal gear eccentric bushing; 9, crescent.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Described in the utility model a kind of internal gear eccentric bushing Excircle machining fixture as shown in Figure 2 comprises clamp body 1, transition disc 2, the first securing member 3, axle 4, the second securing member 5 and balancing weight 6; Described clamp body 1 one ends are provided with transition disc 2; Described transition disc 2 is fixedly linked by the first securing member 3 with fixture 1 body; Described clamp body 1 other end is fixed with axle 4; The diameter of described axle 4 is identical with the diameter of bore of internal gear eccentric bushing; Described the second securing member 5 is connected with clamp body 1 and is positioned at the top of axle 4; Described the second securing member 5 is provided with two balancing weights 6; Also be provided with packing ring 7 on described the second securing member 5; Described the second securing member 5 is screw.
Described in the utility model a kind of internal gear eccentric bushing Excircle machining fixture as shown in accompanying drawing 3,4, add man-hour, at first internal gear eccentric bushing 8 endoporus are placed on the axle 4 of clamp body 1 and position, then the second securing member 5 is passed the crescent 9 on internal gear eccentric bushing 8, internal gear eccentric bushing 8 is fixed on clamp body 1, then the first securing member 3 is connected clamp body with transition disc 2, at last transition disc 2 is arranged on machine tool chief axis and can processes workpiece.Two balancing weights on the second securing member 5 just in time can be placed in the crescent 9 of internal gear eccentric bushing 8, thereby make clamp body 1 can keep balance in the main shaft rotation, reduce to add man-hour internal gear eccentric bushing 8 and produced centrifugal force with the revolution of main shaft, eliminated the issuable circular runout of workpiece bowlder outside fine finishining, guaranteed the Excircle machining precision
Internal gear eccentric bushing Excircle machining fixture of the present utility model, easy and safe to operate, working (machining) efficiency is high, is applicable to batch machining.
Above-mentioned internal gear eccentric bushing Excircle machining fixture, when the quantity of described the first securing member was six, result of use was best.
Be only below concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, within all dropping on the utility model rights protection scope.
