Abstract
The utility model relates to a quick-replacing drill bush device used on a drilling machine processing parts. The drill bush device comprises a drill bush body, a drill rod, a fixed bush and a plurality of positioning parts, wherein, the upper end of the drill bush body is connected with the main shaft of the drilling machine, the lower end is provided with a connecting hole, in which the upper end of the drill rod can be inserted, the hole wall of the connecting hole is provided with a plurality of positioning throughholes, the drill rod is provided with a plurality of positioning pits corresponding to the positions of the positioning throughholes, the positioning parts are placed in the positioning throughholes and the positioning pits, the fixed bush is slidable bushed on the drill bush body, a chute with a downward opening is arranged at a position corresponding to the positions of the positioning parts on the fixed bush, and when the fixed bush slides down, the positioning parts are also positioned in the chute. The positioning parts can apply steel balls, the positioning pits are ball pits matching the steel balls, and spring clips limiting the up-and-down sliding of the fixed bush are mounted on the drill bush body. The quick-replacing drill bush device resolves the problem that parts cannot be processed because of the short travel of the main shaft of the drilling machine, moreover, the drill rod can be quickly connected with the drill bush body, and replacement is convenient.
Description
Technical field
The utility model relates to a kind of fast replacing drill covering device that is used for drill press parts processing.
Background technology
In the drill press parts processing, run into because the drill press spindle stroke is short, can't on part, hole or the situation of thread mill drilling, have adpting flange on the cylindrical as axial workpiece, the connecting hole of adpting flange or the processing of screwed hole through regular meeting.The general way of the bar portion of drill bit being carried out spreading that adopts of prior art is as welding extension bar etc.But the drill bit precision behind the welding lengthening reduces, and is difficult for guaranteeing the dimensional accuracy of part.
Summary of the invention
The purpose of this utility model provides a kind of fast replacing drill covering device, solves the restriction that is subjected to the drill press spindle stroke short, can't carry out the problem of part boring or thread mill drilling.
For achieving the above object, the scheme that the utility model is taked is: a kind of fast replacing drill covering device, comprise the drill bushing body, drilling rod, fixed cover, some keepers, described drill bushing body upper end is connected with drill press spindle, there is connecting hole the lower end, insert in the connecting hole of drill bushing body described drilling rod upper end, have some positioning through hole on the hole wall of described drill bushing body connecting hole, have the some location pit corresponding on the drilling rod with described positioning through hole position, keeper is placed in positioning through hole and the location pit, described being fixedly set on the drill bushing body slidably, the chute that under shed is arranged with the locating piece position corresponding position on the fixed cover, fixed cover makes keeper also be positioned at chute when gliding.
Described keeper is a steel ball, and described location pit is the ball-and-socket that coincide with steel ball, also has upper and lower annular groove on the described drill bushing body, is separately installed with in the upper and lower annular groove fixed cover is slided up and down spacing Spring Card.
When the utility model was used, drill bit was with after drilling rod is connected, and the drill bit shaft portion that is equivalent to extend has solved the problem that can't carry out part processing owing to drill press spindle stroke weak point, and drilling rod is connected fast with the drill bushing body, changes and makes things convenient for.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, the utility model fast replacing drill covering device is made up of drill bushing body 1, drilling rod 2, fixed cover 3, keeper 4.Drill bushing body 1 upper end has plug 1a to be connected with drill press spindle, and there is the connecting hole that is connected with drilling rod 2 upper ends the lower end.Insert in the connecting hole of drill bushing body 1 drilling rod 2 upper ends, and the hole wall upper edge circumference of drill bushing body 1 connecting hole is symmetrically distributed with two positioning round orifice, and is corresponding with the positioning round orifice position, on the drilling rod 2 ball-and-socket arranged.Keeper 4 adopts steel ball to be placed in circular hole and the ball-and-socket.Fixed cover 3 is contained on the drill bushing body 1 and drill bushing body 1 slip relatively, corresponding chute with the steel ball position on the fixed cover 3 with under shed, to lower slider steel ball is entered in the chute fixed cover 3, steel ball can be fixed, realize that drill bushing body 1 is connected with the quick of drilling rod 2, fixed cover 3 is upwards slided, make chute break away from steel ball, take out steel ball, drilling rod 2 can be taken out or changes fast.The hole 2a of drilling rod 2 lower ends is used to the drill bit of packing into.Have up and down two cannelures on drill bushing body 1 cylindrical, Spring Card 5,6 be housed in the cannelure, be used for to fixed cover 3 when connecting or take out drilling rod 2, move down or on the sliding position that moves spacing.
During application, drill bit is connected on the drilling rod 2, makes drill bit shaft portion obtain lengthening, solved and be subjected to drill press spindle stroke weak point can't carry out the problem of part boring or thread mill drilling.Because this device adopts machined to make, can guarantee that drill bit connects the precision of back drill bit, thereby guarantee the dimensional accuracy of part to be processed.
