Abstract
The utility model discloses a device for drilling holes in bulldozer half shaft threads. The device comprises an outer sleeve, drilling sleeves and fastening screws, wherein the outer sleeve is used for being sleeved on a half shaft. The outer sleeve is in the shape of a hollow tube, the inner structure of the outer sleeve is matched with the shape of the outer surface of the bulldozer half shaft, the outer sleeve is provided with screw holes and sleeve holes for drilled holes, the screw holes are used for fixing the outer sleeve, and the drilling sleeves are arranged in the sleeve holes and used for protecting walls of the drilled holes. When the device is used, the fastening screws are screwed into the screw holes, the tail ends of the screws are tightly pressed on the surface of the half shaft, and the outer sleeve with the drilling sleeves is fixed on the half shaft. The device for drilling the holes in the bulldozer half shaft threads has the advantages that the corresponding drilled holes are designed in the device according to hole diameters which are actually needed, the device is sleeved on the half shaft to achieve an ideal positioning effect directly, convenience in actual operation is greatly improved, the process of manual positioning by marking is eliminated, and therefore both errors and labor intensity are reduced.
Description
Technical field
The utility model belongs to machinery manufacturing technology field, relates in particular to drilling equipment on a kind of bull-dozer semiaxis screw thread.
Background technology
At present, 3-￠ 12.5 holes on the cylindrical are bored in bull-dozer semiaxis screw thread processing back.If earlier bore screw thread on the 3-￠ 12.5 holes reprocessing cylindrical at cylindrical, screw thread interrupted cut then, difficulty of processing is very big.If the screw thread on the first processing excircles is drawn 3-￠ 12.5 hole lines at flank again, to use usually vernier card, depth gauge rule detect length and pitch-row from, operate very loaded down with trivial details.Quantity is many simultaneously, can only control at 0.5mm the difficult control in some position by artificial line error minimum.Another aspect drill bit easily skids in flank boring and bores partially, is difficult to reach the drawing positioning requirements.
The utility model content
The technical problems to be solved in the utility model provides drilling equipment on a kind of simple in structure, accurate positioning, the easy to operate bull-dozer semiaxis screw thread.
In order to solve the problems of the technologies described above, the utility model solves the technical scheme that its technical problem adopts and is: drilling equipment on a kind of bull-dozer semiaxis screw thread is provided, comprises be used to the overcoat, drill bushing and the holding screw that are set on the semiaxis;
Described overcoat is hollow tubular; the internal structure of overcoat and bull-dozer semiaxis external surface shape are suitable; described outer putting offers for the trepanning of boring and the screw of fixed jacket; described drill bushing is arranged in the trepanning; for the protection of the hole wall of trepanning, during use, screw in the screw by described holding screw; end with screw is pressed on the semiaxis surface, and the overcoat that will have drill bushing is fixed on the semiaxis.
More accurate for overcoat is cooperated with drill bushing, the utility model is further optimized, described drill bushing and trepanning interference fit.
When making overcoat fixedly and the spacing of semiaxis average, the utility model is further optimized, described screw is three, is equally spaced on the coat.
The utility model is further optimized, and also comprises fastening screw, and after boring finished, described fastening screw was plugged in the described boring.
In order to prevent that the boring procedure overcoat is worn, the utility model is further optimized, and the material of described overcoat is Fine Steel Casting iron, and the material of described drill bushing is carbon tool steel.
The beneficial effects of the utility model are, there is corresponding boring in aperture according to actual needs in the design of this drilling equipment, this drilling equipment is set in the locating effect of directly realizing ideal on the semiaxis, improved the facility of practical operation widely, save by artificial line location, both reduce error, also reduced labour intensity.

The specific embodiment
By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.
See also Fig. 1 and Fig. 6, the embodiment of drilling equipment comprises overcoat 1, drill bushing 2 and holding screw 3 on the utility model bull-dozer semiaxis screw thread; Described overcoat 1 is hollow tubular; the internal mechanism of overcoat 1 and bull-dozer semiaxis shape are suitable; described overcoat 1 is provided with screw 12 and trepanning 11; described screw 12 is three; be equally distributed on the overcoat 1; described drill bushing 2 is arranged in the trepanning 11; it is drill bushing 2 and 11 removable connections of trepanning; as drill bushing 2 and trepanning 11 interference fit or nested the connection; drill bushing 2 is arranged in the trepanning 11 for the protection of the hole wall of holing; because the material of overcoat 1 is No. 45 Fine Steel Casting irons; and the material of drill bushing 2 is the T10A carbon tool steel, and drill bushing 2 quality are harder than overcoat 1, is unlikely to be worn and torn by drill bit so that influence follow-up boring in boring procedure; owing to need bore 3-￠ 12.5 holes at cylindrical after the processing of bull-dozer semiaxis screw thread, so the number of trepanning 11 is three.
When drilling equipment uses on the utility model bull-dozer semiaxis screw thread, earlier drill bushing 2 is squeezed in the trepanning 11, the overcoat 1 that will have a drill bushing 2 semiaxis of packing into, the cylindrical of axle is located (axis direction) with the endoporus of overcoat 1 location (diametric(al)), the step of axle.After having determined the position of boring, three holding screws 3 screw in the screws 12, are pressed on the semiaxis surface with the end of screw, and the overcoat 1 that will have drill bushing 2 is fixed on the semiaxis, and cover can not arbitrarily be rotated, begin afterwards the bull-dozer semiaxis is holed.
In this example, further include fastening screw 4, bore three on the edge arbitrarily
After one of them of hole, in trepanning 11, plug the alignment pin location, bore all the other two holes.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
