Abstract

The utility model relates to a boring grab which comprises a soleplate, a side plate, a positioning plate and a press plate, wherein the soleplate is arranged on a drilling machine table; the side plate is perpendicular to the soleplate and is fixedly arranged; the positioning plate is removably arranged on the side plate and is provided with at least one bore hole; and the press plate is removably arranged on the side plate and is positioned below the positioning plate. The shaft axis of the bore hole is parallel to the surface of the side plate; the lower part of the soleplate is telescopically connected with at least one pair of adjusting members. The adjusting members are arranged at the lower part of the soleplate, so the determination of the instable boring size caused by the original paper washers is avoided; therefore, the boring precision is further improved and the rate of certified products can reach 99% in the processing process. The contact area between the soleplate and the working table is decreased only through that the adjusting members contact with the working table; the relative friction is reduced; the boring grab is easily cleaned; thereby, the work efficiency is greatly improved.

Description

Boring grab

Technical field

The utility model relates to a kind of to realize the anchor clamps of boring on drilling machine.

Background technology

In part processing, utilize the bushing plate anchor clamps giving a kind of processing mode that the drilling and tapping right and wrong are usually seen on part side or the circumference on the drilling machine, existing clamp structure and clamping schematic diagram thereof are referring to Fig. 1 and Fig. 2, it comprises the base plate 1 that is used to be arranged on the drilling machine, with base plate 1 fixing and vertically disposed side plate 2, on side plate 2, be removably connected with location-plate 3 respectively, pressing plate 4, offer of the boring of at least one axis parallel on the location-plate 3 in side plate 2, when needs are holed, base plate 1 is arranged on the workbench of drilling machine, part to be holed is folded between pressing plate 4 and the location-plate 3, because side plate 1 and base plate 8 perpendicularity are bad sometimes, precision problem of drilling machine own and base plate and problems such as the workbench large tracts of land contacts, drilling rubbish factor such as can't discharge causes institute's machining hole perpendicularity deviation.In the prior art, adopt paper washer to overcome the problems referred to above usually, but, cause the paper position indefinite, will cause the size instability owing to bore the two holes anchor clamps that reverse; Moreover owing to the reason of paper sheet thickness can not reach our desirable thickness sometimes, precision just is affected.Therefore, this mode makes that the percentage of A-class goods is not too high, generally 93%.

The utility model content

The utility model purpose is the boring grab that provides a kind of machining accuracy higher 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 boring grab, comprise the base plate that is arranged on the Drilling machines bench, and the side plate that fixedly install vertical with described base plate, be removably disposed on the described side plate and offer at least one boring location-plate, be removably disposed on the described side plate and be positioned at the pressing plate of described location-plate below, the axial line of described boring parallels with described surface of side plate, and telescopically is connected with at least one pair of regulating part below described base plate.

Further, described regulating part is an adjustment screw.

Described regulating part is two pairs, and described two pairs of regulating parts closely are arranged on four bights of described base plate.

Because the application of technique scheme, the utility model compared with prior art has following advantage: owing in floor below regulating part is set, the bore size of having avoided adopting original paper washer to cause is unsettled to be determined, make borehole accuracy be further enhanced, the percentage of A-class goods can reach 99% in process, and only by regulating part contact workbench, make base plate and workbench contact area reduce, corresponding friction reduces, and is easy to cleaning, thereby makes operating efficiency obtain bigger raising.

The specific embodiment

Below in conjunction with accompanying drawing, describe particular content of the present utility model in detail for example:

Boring grab as shown in Figure 3 and Figure 4, comprise base plate 1, side plate 2, side plate 2 and base plate 1 vertical and setting regularly, on side plate 2, also be removably connected with location-plate 3 and pressing plate 4, pressing plate 4 is positioned at the below of location-plate 3, offer boring 31 and locating hole 32 on the location-plate 3, the axial line of boring 31 parallels with the inner surface of side plate 2, the inner surface of the axial line of locating hole 32 and side plate 2 is perpendicular, so location-plate 3 is fixed on the side plate 2 by locating hole 32, pressing plate 4 is fixed on part to be bored on the side plate 2 by back supporting screw 41 and trip bolt respectively, lower surface at base plate 1 also is provided with regulating part 5, and this regulating part 5 is adjustment screw in the present embodiment, and regulating part 5 is arranged on four bights of base plate 1, like this in process, when finding the perpendicularity of having holed, deviations such as the depth of parallelism can be passed through to regulate the screw of corresponding position, thereby be made side plate 2 and base plate 1 integral body do corresponding adjustment, therefore, guaranteed drilling accuracy.Simultaneously, contact with work top, reduced contact area, make drilling rubbish in time to discharge, further guaranteed the high efficiency of processing by screw.

The utility model anchor clamps in manufacturing process, should note following some:

1, the anchor clamps side plate will grind on flat stone mill vertically with base plate, the outside and the inner face of clamping parts of side plate also will guarantee parallelly, reduces regulated quantity to reach as far as possible, guarantees original anchor clamps rigidity, the clamping face has been put down, also easy to clean has promptly guaranteed the surface smoothness of part also to have guaranteed perpendicularity.

2, location, the brill of the screw bottom outlet of pressing plate, expand, attack and should after the depth of parallelism is ground, carry out, guarantee that the thrust of pressing plate is vertical with face.

3, it is parallel with the anchor clamps base plate to use preceding need that adjustment screw is transferred to, and gets a test specimen, adjusts according to actual conditions again, can effectively reduce regulated quantity, guarantees the rigidity of anchor clamps itself.
