A kind of combined type exhibition cutter is provided, it is characterized in that: it comprises an axle bed that is fixedly connected with cylinder block, be equipped with a rotating shaft in the axis hole of described axle bed, described rotating shaft front end is provided with the exhibition tool rest, described exhibition tool rest front end is provided with a drill bit holder, also is provided with an opening that is connected with the hollow axocoel of rotating shaft on the described exhibition tool rest; Described opening part embeds an exhibition cutter head; Described exhibition cutter head is connected with described exhibition tool rest axle, and the wedge afterbody of exhibition cutter head partly extend in the hollow axocoel of described rotating shaft, and matches with the wedge front portion of push rod in placing the hollow axocoel.
The wedge front portion of described push rod is provided with an arc convex, when described push rod moves ahead, promote described arc convex and contact with the wedge afterbody of exhibition cutter head, arc convex protracts in the process, and the wedge afterbody that will open up cutter head holds up gradually thereby so that open up the head of cutter head and fall gradually.
The partial fixing that described rotating shaft is positioned on the cylinder block is connected with a belt pulley, and described push rod afterbody is connected with bearing block, and described bearing block is connected with the cylinder of described cylinder block; One back-moving spring is set on the described push rod, and described back-moving spring front end withstands belt pulley, and the bearing on the bearing block is withstood in its rear end; When cylinder axis was return, under action of reset spring, the head of exhibition cutter head lifted gradually.
Through the present invention of above setting in use, described combined type exhibition cutter is arranged on the planker, described belt pulley driven rotary axle rotates, cylinder on described cylinder block holds lower, and push rod moves forward, until the exhibition cutter that arranges on the exhibition cutter head pushes against insert surface, inserts maintains static, when planker moved, the exhibition cutter on the exhibition cutter head was made circular motion along insert axis, and the annular groove on the processing inserts; When the drill bit that arranges on the rotating shaft moves ahead under planker drives inserts is punched; Like this, during drill bit 91 punching, exhibition cutter 8211 forms groove milling to the insert surface groove synchronously.
The present invention can be applicable to the processing of inserts, valve, pipe fitting part, has improved the positioning accuracy and the working (machining) efficiency that add the workpiece in man-hour, has the automaticity height, the advantage of applied range,
