Abstract
The invention discloses a drilling and positioning device for hollow pipes. The drilling and positioning device for hollow pipes can fix a steel sleeve conveniently and rapidly before the steel sleeve is drilled, and comprises a rack. The rack is connected with a positioning mandrel horizontally extending out. The external diameter of the positioning mandrel is equal to the internal diameter of the steel sleeve to be machined. The positioning mandrel is provided with an annular boss. One end face of the boss is a positioning face for positioning the end face of the steel sleeve. A gasket is fixed to the end, penetrating through the steel sleeve, of the positioning mandrel through a nut. When the steel sleeve is at the machining station, the inner wall of the steel sleeve is connected with the positioning mandrel in a sleeving mode, the end face of the steel sleeve abuts against the positioning face, and the other end face of the steel sleeve abuts against the gasket. The rack is further connected with a drill plate which is provided with a rotary sleeve for positioning a drill bit. When the steel sleeve to be drilled is positioned on the device, the preset rotary sleeve aligns at the design processing position, the whole steel sleeve is also fixed with multiple positioning faces, and a drilling machine can drill workpieces accurately.
Description
Technical field
The present invention relates to a kind of steel bushing boring grab.
Background technology
Steel bushing (i.e. hollow pipe) is the parts be widely used in machine-building, may be used for various environment, in some heavy engineering machineries, in order to prevent the part axis hole wearing and tearing caused because there are wearing and tearing between part and axle, usually need steel bushing is installed between axle and part.
On steel bushing, boring is very common process requirements.Due to the requirement to Drilling operation precision, usually need the method adopting line centering when steel bushing is holed, determine the part quality after processing, but when parts batch is larger, the shortcoming adopting the method for line centering just to manifest him is come: efficiency is low, and working strength is large.Be unfavorable for the need of production of modern plant.
Summary of the invention
The invention is intended to provide a kind of hollow pipe drilling-hole positioning device, fixing with before the boring conveniently realizing steel bushing.
Hollow pipe drilling-hole positioning device in this programme, comprise frame, frame is connected with the apotting spindle that level is stretched out, the external diameter of apotting spindle equals the internal diameter of steel bushing to be processed, apotting spindle is provided with the boss of annular, one end face of boss is the locating surface for locating steel bushing end face, apotting spindle is fixed with packing ring through the other end of steel bushing by nut, when steel bushing is in processing stations, its inwall and apotting spindle are socketed, the end face of steel bushing pushes against locating surface, other end and the packing ring of steel bushing push against, frame is also connected with bushing plate, bushing plate is provided with the pivoted housing for drill bit location.
When the steel bushing of processing hole to be drilled is located in this device, namely the pivoted housing pre-seted targeted by design Working position, steel bushing entirety also fix by multiple locating surface, rig can carry out drilling operation accurately on workpiece.
Further, described locating surface is provided with anti-rotation pin.Can coordinate with features such as the holes on steel bushing, steel bushing be realized to the location of the anglec of rotation.
Further, bushing plate is bolted in frame.According to different processing needs, the bushing plate of various criterion size can be changed.
Further, one end that apotting spindle connects with frame is connected by nut.The apotting spindle of different size can be changed as required.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: frame 1, apotting spindle 2, bushing plate 3, drill bushing 4, open washer 5, nut 6, anti-rotation pin 7, nut 8.
Embodiment is substantially as shown in Figure 1: frame 1 is provided with apotting spindle 2, and the left end that apotting spindle connects with frame is connected by nut 8, and apotting spindle is provided with the breach abdicating bit operation space, and it is positioned at the below of machining hole on steel bushing.
The external diameter of apotting spindle equals the internal diameter of steel bushing to be processed, and apotting spindle is provided with the boss of annular, and the left end face of boss is tight against in frame, and its other end is the locating surface for locating steel bushing end face, and locating surface is provided with anti-rotation pin 7.
Apotting spindle is fixed with open washer 5 through the right-hand member of steel bushing by nut, and the opening direction of open washer down.When steel bushing is in processing stations, its inwall and apotting spindle are socketed, the end face of steel bushing pushes against locating surface, the open washer of the other end of steel bushing is pushed against by nut 6, frame also there is the bushing plate 3 of level by bolt-connection, bushing plate is provided with the pivoted housing 4 for drill bit location, and the axis of pivoted housing keeps vertically.
Workpiece is using endoporus and end face thereof as positioning datum, keeps in touch, thus determine the tram of workpiece in fixture with the setting element (apotting spindle 2 and end surface supporting thereof) on fixture.Fastening nut 6, by open washer 5, is pressed on setting element securely by workpiece end face.Because the center of the drill bushing 4 on bushing plate 3 is to the distance of setting element end face, determine according to the size of workpiece Shang Kong center to workpiece end face, therefore, ensure that the drill bit that drill bushing 4 is guided, workpiece has the Working position that correct, and work in-process can prevent again the axis of drill bit from drawing partially.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
