Abstract

A kind of rat holing frock, comprise base plate, for penetrating the positioning core axle in pump body dead eye, positioning core axle top is provided with one and passes and the drill bushing of fast changeable for drill bit, a stop pin is housed between drill bushing and positioning core axle, drill bushing bottom is positioned at pump body die cavity, inclined hole on drill bushing and pump body between ring shaped oil passage with oil sealing hole is coaxial, base plate left side is provided with one piece and contacts with pump body bottom end face and inclined hole can be made to be the support plate of vertical state, is connected bottom positioning core axle with support plate.A kind of rat holing frock of the utility model processing and fabricating is simple, low cost of manufacture, without the need to radial drill, only common driller need be used can to process the inclined hole on pump body between ring shaped oil passage and oil sealing hole.

Description

A kind of rat holing frock
Technical field:
The utility model relates to a kind of frock clamp, is specifically that one is arranged on drilling machine, facilitates the rat holing frock that workman processes the inclined hole on pump body between ring shaped oil passage and oil sealing hole.
Background technology:
Fig. 2 is existing a kind of pump body, has an inclined hole 5 between its ring shaped oil passage 6 and oil sealing hole 3, and the effect of this inclined hole 5 is guided in ring shaped oil passage 6 by the oil being leaked to oil sealing hole 3 position by dead eye 12.This inclined hole 5 is owing to being sink in die cavity, pump body 4 must just can be holed by slant setting, be generally and make pump body 4 convenient mounting and clamping, bushing plate must have certain height apart from pump body 4, drill bit can be caused like this to lengthen, and meanwhile, bench drill stroke is also inadequate, fixture need move on radial drill together with pump body 4, so then causes the waste of resource.
Utility model content:
The technical problems to be solved in the utility model is, provides a kind of processing and fabricating simple, low cost of manufacture, without the need to radial drill, and the rat holing frock that only common driller need be used can to process the inclined hole on pump body between ring shaped oil passage and oil sealing hole.
Technical solution of the present utility model is, there is provided a kind of rat holing frock with following structure: comprise base plate, for penetrating the positioning core axle in pump body dead eye, positioning core axle top is provided with one and passes and the drill bushing of fast changeable for drill bit, a stop pin is housed between drill bushing and positioning core axle, drill bushing bottom is positioned at pump body die cavity, inclined hole on drill bushing and pump body between ring shaped oil passage with oil sealing hole is coaxial, base plate left side is provided with one piece and contacts with pump body bottom end face and inclined hole can be made to be the support plate of vertical state, be connected with support plate bottom positioning core axle.
After adopting above structure, compared with prior art, a kind of rat holing frock of the utility model has the following advantages:
1, a kind of rat holing of the utility model frock makes more convenient to operate, applicable by the relative position of change pump body Set and Positioning mode and drill bushing;
2, drill bushing bottom is deep in the die cavity of pump body, this structure substantially reduces the length of drill press spindle stroke and drill bit, and without the need to radial drill, common driller can be processed the inclined hole on pump body between ring shaped oil passage and oil sealing hole, facilitate boring, working (machining) efficiency is improved;
3, drill bushing adopts quick change construction, both can be convenient for changing drill bushing, also workpiece easy to setup after drill bushing wearing and tearing, and effectively prevent positioning core axle simultaneously and directly contact with drill bit and the wearing and tearing that produce;
4, with the dead eye of pump body and bottom end face location, make the structure of a kind of rat holing frock of the utility model very simple, clamping also facilitates, and is suitable for very much inclined hole boring;
5, processing and fabricating is simple, and low cost of manufacture, the process-cycle is short.
Accompanying drawing illustrates:
Fig. 1 is that in a kind of rat holing frock of the utility model, clamping has master during pump body to look sectional structure schematic diagram;
Fig. 2 is the three-dimensional structure for amplifying schematic diagram of prior art pump body.
Detailed description of the invention:
Below in conjunction with the drawings and specific embodiments, a kind of rat holing frock of the utility model is described in further detail:
As depicted in figs. 1 and 2, in this embodiment, the utility model rat holing frock comprises base plate 7, for penetrating the positioning core axle 11 in pump body 4 dead eye 12, positioning core axle 11 top is provided with one and passes and the drill bushing 2 of fast changeable for drill bit, a stop pin 1 is housed between drill bushing 2 and positioning core axle 11, drill bushing 2 bottom is positioned at pump body 4 die cavity, pump body 4 there is an inclined hole 5 between ring shaped oil passage 6 and oil sealing hole 3, drill bushing 2 is coaxial with inclined hole 5, base plate 7 left side is provided with one piece and contacts with pump body 4 bottom end face 10 and can make the support plate 9 of inclined hole 5 in vertical state, support plate 9 and base plate 7 weld together, be connected with support plate 9 by locking nut 8 bottom positioning core axle 11.
The using method of the utility model rat holing frock is: as depicted in figs. 1 and 2, the dead eye 12 of pump body 4 is aimed at positioning core axle 11 be inserted in, ensure that the bottom end face 10 of pump body 4 is close to support plate 9, and drill bushing 2, stop pin 1 are inserted positioning core axle 11 respectively, respectively stop pin 1, drill bushing 2 are taken out from positioning core axle 11 again after boring terminates, finally pump body 4 is taken out from fixture.After a long time use, if the wearing and tearing of drill bushing 2 endoporus, a new drill bushing is changed.
Above-described embodiment is only be described preferred embodiment of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
