Description
Technical field
The utility model relates to frock clamp field, and specifically, the utility model relates to a kind of boring grab.。
Background technology
Often need in process of factory production hole in the end of axle, need holder to keep the precision of boring in boring procedure, holder more firm, the precision of boring is higher.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of boring grab, the clamp axis workpiece that this fixture can be comparatively firm, ensures borehole accuracy.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of boring grab, comprise base, also comprise chuck, bearing, eccentric wheel and spring, described spring housing is outside stud, the middle part of chuck is fixed on by nut and pad, stud is vertically fixed on base, and described bearing and base are fixed on same horizontal plane, and eccentric wheel is hinged on bearing by guide bracket, eccentric pivot is hinged on one end of chuck, eccentric surfaces connecting handle.
Preferably, the clamping part middle part of described chuck is provided with location-plate.
Preferably, the end of described base is provided with positioning sleeve, positioning sleeve internal fixtion locating dowel, and described positioning sleeve is arranged on front end, grips portion.
Adopt the technical solution of the utility model, following beneficial effect can be obtained:
Boring grab of the present utility model, is applied to eccentric wheel in fixture, utilizes eccentric special construction, and drive chuck clamping or unclamp workpiece, clamping work pieces carries out follow-up bore operation.
Accompanying drawing explanation
Brief description is made to the content expressed by each accompanying drawing of this description and the mark in figure below:
Fig. 1 is structural representation of the present utility model;
Mark in above-mentioned figure is: 1, positioning sleeve; 2, locating dowel; 3, chuck; 4, location-plate; 5, base; 6, nut; 7, packing ring; 8, spring; 9, eccentric wheel; 10, pin joint; 11, bearing; 12, handle; 13, axle.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the effect and operation principle etc. of detailed description of the invention of the present utility model as the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part are described in further detail.
As shown in Figure 1, this boring grab, comprise base 5, chuck 3, bearing 11, eccentric wheel 9 and spring 8, spring 8 is enclosed within outside stud, is fixed on the middle part of chuck 3 by nut 6 and pad 7, stud is vertically fixed on base 5, bearing 11 and base 5 are fixed on same horizontal plane, and eccentric wheel 9 is hinged on bearing 11 by guide bracket, and the pivot of eccentric wheel 9 is hinged on one end of chuck 3, in Fig. 1, the position of pin joint 10 is pin joint place, the surperficial connecting handle 12 of eccentric wheel 9.
The clamping part middle part of chuck 3 is provided with location-plate 4, and the middle part that location-plate 4 is placed on chuck 3 clamping part can prevent the clamping tension of chuck 3 pairs of axles 13 and leave impression on the surface of axle 13, affects the processing of workpiece.The end of base 5 is provided with positioning sleeve 1, positioning sleeve 1 internal fixtion locating dowel 2, positioning sleeve 1 is arranged on front end, grips portion, think positioning sleeve be parallel to axle 13 axis arrange, so can judge whether axle 13 is clamped on correct position by observing locating dowel 2 with the relative position of axle 13 axis.
During use, axle 13 is placed in chuck 3, after the relative position of locating dowel of having good positioning 2 and axle 13 axis, press down handle 12, chuck 3 forms a lever between eccentric wheel 9 and stud, after chuck 3 clamp shaft 13, to axle 13 type bore operation, bore release handle 12 behind hole.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out; or design of the present utility model and technical scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
