Description
Technical field
The utility model relates to a kind of bush end face installing hole tool for processing.
Background technology
Belt transmission is a kind of kind of drive be in daily use, and in belt transmission, belt pulley and lining are very common.
In order to strengthen the bond strength between belt pulley and belt pulley fixed axis, lining usually also can be used to connect belt pulley and belt pulley fixed axis.
Add man-hour carrying out end face installing hole to lining, inventor encounters problem, and clamping tool of the prior art often fixes insecure when clamping lining or operation is too complicated, and these not only have impact on machining accuracy, and have impact on production efficiency.
Utility model content
The utility model is intended to provide a kind of bush end face installing hole tool for processing, to enhance productivity.
Bush end face installing hole tool for processing in this programme, comprise bushing plate, lock-screw, steel ball, axle, pin and spring, axle upper end is protruding to be fixed with bushing plate, on bushing plate, circumference is embedded with drill bushing, spindle center is provided with the cavity running through axle vertically, lock-screw is connected in the middle part of cavity from cavity threaded upper ends, lock-screw lower end and the steel ball be positioned in the middle part of cavity offset, axle circumference slidably connects the pin of multiple band wedge mouth, the wedge mouth place of pin all can be against on steel ball, and pin outer face is provided with the groove holding spring.
Compared with prior art, the utility model has the advantage of: during work, workpiece is enclosed within axle, workpiece end face is against on bushing plate, then screw lock-screw, lock-screw moves down against steel ball, and steel ball is against the wedge mouth place outwards movement of pin, pin against the force of the spring is by lining fixation, and then drill bit stretches into processing lining from drill bushing; After machining, oppositely unscrew lock-screw, pin is travelling backwards under the action of the spring, unclamps workpiece.This programme convenient mounting and clamping is quick, processing ease, can stationary bushing fast, substantially increases production efficiency.
Further, be connected by screw fixing between drill bushing and bushing plate, facilitate installing/dismounting.
Further, be connected by screw by finger setting between bushing plate and axle, accurate positioning and facilitate installing/dismounting.
Further, lock-screw upper end is provided with the clamping part of band slip-resistant texture, facilitates rotation lock screw.
Further, cavity lower end diameter is less than steel ball size, prevents steel ball from departing from cavity.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description comprises: bushing plate 1, lock-screw 2, steel ball 3, axle 4, pin 5, spring 6.
Embodiment is substantially as shown in Figure 1: bush end face installing hole tool for processing comprises bushing plate 1, lock-screw 2, steel ball 3, axle 4, pin 5 and spring 6, axle upper end is protruding to be fixed with bushing plate, to be connected by screw by finger setting between bushing plate and axle, accurate positioning and facilitate installing/dismounting, on bushing plate, circumference is embedded with drill bushing, be connected by screw fixing between drill bushing and bushing plate, facilitate installing/dismounting, spindle center is provided with the cavity running through axle vertically, lock-screw is connected in the middle part of cavity from cavity threaded upper ends, lock-screw upper end is provided with the clamping part of band slip-resistant texture, facilitate rotation lock screw, lock-screw lower end and the steel ball be positioned in the middle part of cavity offset, cavity lower end diameter is less than steel ball size, prevent steel ball from departing from cavity, axle circumference slidably connects the pin of three band wedge mouths, the wedge mouth place of pin all can be against on steel ball, pin outer face is provided with the groove holding spring.
This frock is for processing the end face installing hole of lining, particularly suitable during D/d >=2.
Compared with prior art, the utility model has the advantage of: during work, workpiece is enclosed within axle, workpiece end face is against on bushing plate, then screw lock-screw, lock-screw moves down against steel ball, and steel ball is against the wedge mouth place outwards movement of pin, pin against the force of the spring is by lining fixation, and then drill bit stretches into processing lining from drill bushing; After machining, oppositely unscrew lock-screw, pin is travelling backwards under the action of the spring, unclamps workpiece.This programme convenient mounting and clamping is quick, processing ease, can stationary bushing fast, substantially increases production efficiency.
Above-described is only embodiment of the present utility model, 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 the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.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.
