Radial drilling device for shaft sleeve parts

The invention discloses a radial drilling device for shaft sleeve parts. The radial drilling device comprises a clamp, a drilling jig component, a positioning mandrel, a shaft sleeve part positioning mechanism and an indexing mechanism, the positioning mandrel is supported on the clamp rotatably, the shaft sleeve part positioning mechanism is mounted on the positioning mandrel so as to lock one shaft sleeve part on the positioning mandrel, the drilling rig component is mounted at the top end of the clamp so as to be used for drilling the shaft sleeve part, the indexing mechanism comprises a positioning pin, an indexing plate, an indexing pin and a return spring, the indexing plate sleeves the positioning mandrel, a plurality of indexing grooves and a plurality of positioning holes corresponding to to-be-drilled positions of the shaft sleeve part are formed in the indexing plate, each indexing groove is of an internal arc half-concave sphere structure, the front end of the indexing pin is provided with an arc ball head matched with the indexing grooves, one end of the return spring butts against the clamp, and the other end of the same butts against the indexing pin. By the radial drilling device which is simple and convenient to operate, high positioning accuracy in drilling can be achieved, and radial multi-hole indexing machining is easy to realize.
