Description
Technical field
The utility model relates to a kind of auxiliary stationary fixture, is specifically applicable to the fixing of workpiece.
Background technology
Along with the develop rapidly of modern industry, the mode of traditional artificial work has been difficult to the needs meeting modernization large-scale production, therefore, the use of automation equipment is got more and more, reason is the action such as fixing, processing, transfer that these automation equipments can complete all kinds of workpiece fast, wherein the fixing link of workpiece is even more important, if workpiece is fixing not firm, it will inevitably produce when bearing cutting force in process and rock, so very easily cause mismachining tolerance, therefore, these automation equipments needing can the fixture of firm fixation workpiece.
In addition, on firm fixing basis, the axis of workpiece, especially cylindrical work axis must with horizontal plane or parallel, can process accurately workpiece like this, but, existing workpiece fixed jig, complete but can not detect workpiece after workpiece is fixed axis whether with horizontal plane or parallel, so very easily cause larger mismachining tolerance.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of stationary fixture can guaranteeing machining accuracy.
For solving the problems of the technologies described above, the utility model provides a kind of auxiliary stationary fixture, comprises pedestal, described pedestal has the workpiece slot matched with workpiece end, and in described workpiece slot, symmetry is provided with the first fore-set and the second fore-set;
The end face that described first fore-set and the second fore-set contact with workpiece is inwardly formed porose along its axis;
Be provided with flexible member in described hole, the top of described flexible member is connected with push rod, and described push rod can extend to the outside in described hole by described flexible member;
The side of described first fore-set and the second fore-set is respectively arranged with a gear, and described gear is mutually meshing with the side of described push rod, and also meshing on described gear have a tooth bar, and one end of described tooth bar extends to the outside of described workpiece slot.
Described flexible member is helical spring.
The end face that described first fore-set contacts with workpiece is provided with rubber layer.
The end face that described second fore-set contacts with workpiece is provided with rubber layer.
The end face that described push rod contacts with workpiece is provided with rubber layer.
The horizontal cross-section of described workpiece slot is circular.
Compared with prior art, the beneficial effects of the utility model are: because the utility model is after place work piece, when axis and the horizontal plane of workpiece, workpiece is in normal place, each push rod is stressed identical, every root push rod is all in retraction hole, and drive each gear to produce the revolution of equivalent, the every toothed rack of such drive produces identical contracting amount, and when workpiece tilts, namely there is the angle of a non-90 degree between the axis of workpiece and horizontal plane, at this moment the stressed difference of each push rod, amount of recovery is also different, each gear is driven to produce the revolution of inequality, the every toothed rack of such drive produces not identical contracting amount, after person to be operated finds this phenomenon, workpiece will be adjusted, thus avoid unnecessary mismachining tolerance, therefore the utility model can guarantee machining accuracy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: pedestal 2, workpiece slot 4, the first fore-set 6, second fore-set 8, hole 10, flexible member 12, push rod 14, gear 16, tooth bar 18.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with embodiment and accompanying drawing, the utility model is described in further details.At this, exemplary embodiment of the present utility model and illustrating for explaining the utility model, but not as to restriction of the present utility model.
Shown in Figure 1, one of the present utility model assists stationary fixture, comprise the pedestal 2 be fixed on lathe, the center of this pedestal 2 is provided with the workpiece slot 4 matched with workpiece end, symmetrically in workpiece slot 4 be provided with the first fore-set 6 and the second fore-set 8, this first fore-set 6 and the second fore-set 8 are positioned at the two ends of the same diameter of same circle; The end face that first fore-set 6 and the second fore-set 8 contact with workpiece simultaneously inwardly forms porose 10 along its axis; Be provided with preferably helical spring flexible member 12 in hole 10, the top of this flexible member 12 is connected with push rod 14, and push rod 14 can extend to the outside in hole 10 by described flexible member 12; A gear 16 is respectively arranged with in the side of the first fore-set 6 and the second fore-set 8, this gear 16 is mutually meshing with the side of push rod 14, namely the surface that push rod 14 contacts with gear 16 is provided with tooth, and also meshing on gear 16 have a tooth bar 18, and one end of this tooth bar 18 extends to the outside of workpiece slot 4.Designing principle of the present utility model based on said structure is: in workpiece slot during non-place work piece, push rod 14 stretches out hole 10 under the effect of flexible member 12, gear 16 is static, the length that every toothed rack 18 stretches out pedestal 2 is equal, after place work piece, when axis and the horizontal plane of workpiece, workpiece is in normal place, each push rod 14 is stressed identical, every root push rod 14 is all in retraction hole 10, and drive each gear 16 to produce the revolution of equivalent, the every toothed rack of such drive 18 produces identical contracting amount, and when workpiece tilts, namely there is the angle of a non-90 degree between the axis of workpiece and horizontal plane, at this moment the stressed difference of each push rod 14, amount of recovery is also different, each gear 16 is driven to produce the revolution of inequality, the every toothed rack of such drive 18 produces not identical contracting amount, after person to be operated finds this phenomenon, workpiece will be adjusted, thus avoid unnecessary mismachining tolerance, therefore the utility model can guarantee machining accuracy.
Surface for protection workpiece in actual use is injury-free; the end face that first fore-set 6 contacts with workpiece is provided with rubber layer; the end face that second fore-set 8 contacts with workpiece is provided with rubber layer, the end face that push rod 14 contacts with workpiece is provided with rubber layer.The utility model is specially adapted to cylindrical work in addition, and namely the horizontal cross-section of workpiece slot 4 is circular.
