Description

A kind of circular shaft drilling jig

Technical field

The utility model relates to a kind of fixture, particularly relates to a kind of circular shaft drilling jig.

Background technology

Circular shaft-type parts is common part in mechanical processing industry, and its shape is cylindrical, multi-size, and material mostly is steel part, and circular shaft-type parts, after turnery processing, all will get out various decile connection holes on its one end or two terminal circle side face on drilling machine.This some holes all needs, with common vertical type rocker arm drilling machine processing, due to the variable lengths of Short Axis Kind of Parts, adding man-hour at present, needing ceaselessly to change fixture, labor intensive, and cause drilling efficiency low.

Application number is that 201020285919.7 " drilling equipment for drilling circumference of circular shaft parts " disclose a kind of drilling equipment for drilling circumference of circular shaft parts, comprise body, bushing plate is provided with above described body, described bushing plate is provided with drill jig hole, described body is provided with disk, be provided with stay bolt in described disk, the described stay bolt left side is provided with clamp nut, and described disk is provided with calibration alignment pin.This equipment improves machining accuracy, but disposablely also can only process one, and can only process the circular shaft-type parts of a length.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, and provides a kind of circular shaft drilling jig.

The utility model has come by the following technical programs:

A kind of circular shaft drilling jig, comprise with the use of upper fixture and lower clamp, described upper fixture and position corresponding to lower clamp all have semicircle groove, described semicircle groove while be provided with baffle plate, described baffle plate inserts in lower clamp by the draw-in groove on lower clamp, described draw-in groove is multiple, be set in parallel on lower clamp, and perpendicular to described semicircle groove, on described upper fixture, the position of corresponding lower clamp also has draw-in groove, the edge correspondence position of described upper fixture and lower clamp has screwed hole, one bolt coordinates with nut through upper fixture and lower clamp and upper fixture and lower clamp is clamped.

Described a kind of circular shaft drilling jig, described semicircle groove is multiple.

Described a kind of circular shaft drilling jig, the edge of the semicircle groove of described upper fixture is marked with angle mark.

Described a kind of circular shaft drilling jig, described semicircle groove inner surface is elastic layer.

Described a kind of circular shaft drilling jig, described upper fixture and lower clamp are square, and the quantity of described screwed hole is 4, are positioned on four angles of fixture.

Described a kind of circular shaft drilling jig, described lower clamp also offers locating hole.

The beneficial effect that the utility model reaches: circular shaft boring grab structure of the present utility model is simple, clamping is stable, by upper fixture and lower clamp with the use of, a fixation is risen to the radial direction of circular shaft, by baffle plate axial device fixation to circular shaft, thus clamping circular shaft, because the position of baffle plate is adjustable, so can clamp the circular shaft of different length, do not need to change fixture frequently, use convenient.

Accompanying drawing explanation

Fig. 1 is the upward view of fixture on the utility model.

Fig. 2 is the top view of the utility model lower clamp.

Fig. 3 is the right view of Fig. 1.

In figure: 1, upper fixture, 2, lower clamp, 3, semicircle groove, 4, baffle plate, 5, draw-in groove, 6, screwed hole, 7, elastic layer, 8, locating hole.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.

As shown in the figure, a kind of circular shaft drilling jig of the present utility model, comprise with the use of upper fixture 1 and lower clamp 2, the position of described upper fixture 1 and lower clamp 2 correspondence all has semicircle groove 3, described semicircle groove 3 while be provided with baffle plate 4, described baffle plate 4 inserts in lower clamp 2 by the draw-in groove 5 on lower clamp 2, described draw-in groove 5 is multiple, be set in parallel on lower clamp 2, and perpendicular to described semicircle groove 3, on described upper fixture 1, the position of corresponding lower clamp 2 also has draw-in groove 5, the edge correspondence position of described upper fixture 1 and lower clamp 2 has screwed hole 6, one bolt (not shown) coordinates with nut (not shown) through upper fixture 1 and lower clamp 2 and upper fixture 1 and lower clamp 2 is clamped.

Described semicircle groove 3 is multiple, and the edge of the semicircle groove 3 of described upper fixture is marked with angle mark, and described semicircle groove 3 inner surface is elastic layer 7.Described upper fixture 1 and lower clamp 2 are square, and the quantity of described screwed hole 6 is 4, are positioned on four angles of fixture 1.Described lower clamp 2 also offers locating hole 8.

Semicircle groove 3 is multiple, gets final product the multiple circular shaft of clamping simultaneously, increases work efficiency; The angle mark at the edge of semicircle groove 3 can play a mark action to the position of circular shaft; elastic layer 7 can reduce the friction of circular shaft in semicircle groove 3; thus protection circular shaft is not impaired; screwed hole 6 is positioned on four angles of fixture 1; mean forced and easily clamping, locating hole 8 can position fixture.

Circular shaft boring grab of the present utility model in use, circular shaft is placed in the semicircle groove 3 of lower clamp 2, baffle plate 4 is inserted draw-in groove 5, to circular shaft while be fixed, reserve the processing part of circular shaft outside fixture, subsequently upper fixture 1 is clamped by bolt and nut with lower clamp 2, can be fixed the radial direction of circular shaft, after clamping, drilling operation can be carried out to circular shaft.

The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
