Radial drilling device of shaft sleeve type parts

The utility model discloses a radial drilling device of shaft sleeve type parts. The radial drilling device comprises a clamp body, a drilling die component, a positioning mandrel, a shaft sleeve type part positioning mechanism and an indexing mechanism. The positioning mandrel is rotationally supported on the clamp body, the shaft sleeve type part positioning mechanism is mounted on the positioning mandrel so as to conveniently lock the shaft sleeve type parts on the positioning mandrel, and the drilling die component is mounted at the top end of the clamp body so as to drill the shaft sleeve type parts. The indexing mechanism comprises a positioning pin, an index plate, an index pin and a reset spring, the index plate is sleeved with the positioning mandrel and provided with a plurality of index grooves and a plurality of positioning holes corresponding to the drilled holes of the shaft sleeve type parts, each index groove is of an inner-arc concave hemisphere structure, the front end of the index pin is provided with an arc-shaped ball head matched with the index grooves, one end of the reset spring is abutted against the clamp body, and the other end of the reset spring is abutted against the index pin. The radial drilling device can drill the holes having high positioning accuracy, radial multi-hole index machining is easy to realize, and the radial drilling device is simple and convenient to operate.
