Disk punching device

Abstract

The invention belongs to the technical field of disk type component drilling tools and particularly discloses a disk punching device. The disk punching device comprises a rack, a drive mechanism, a clamping device, a workbench and a drilling mechanism. The drilling mechanism comprises a first motor, a drive gear and a driven gear. The driven gear is provided with an inner threaded hole, the innerthreaded hole of the driven gear is provided with a threaded rod, the threaded rod is sleeved with a tapered rotor, and the tapered rotor is internally provided with a first groove. The threaded rod is provided with a first protrusion, the lower end of the threaded rod is connected with a tapered column, a plurality of tapered drill rods are arranged on the circumferential side of the tapered rotor, the lower portions of the tapered drill rods are sleeved with drill bushings, one sides of the drilling bushings are connected with springs fixed to the rack, the other sides of the drilling bushings are in sliding connection with the side wall of the tapered column, the drill bushings are internally provided with second grooves, the tapered drill rods are provided with second protrusions, andthe lower ends of the tapered drill rods are connected with drill bits. By adopting the technical scheme, the working efficiency can be improved, and the problem that disks with different diameters but with same index holes cannot be machined is solved.

Description

technical field

[0001] The invention belongs to the technical field of drilling tools for disc parts, in particular to a disc drilling device. Background technique

[0002] Disc-like parts are very common in the mechanical manufacturing process. Due to the needs of process design, sometimes it is necessary to drill equal parts on the circular end surface of the outer circumference of the disc. At this stage, the general practice of the staff is to clamp the workpiece on the dividing head, use the dividing head to divide and mark the position of the workpiece to be drilled, and finally use the drill bit to drill the hole, or directly install the dividing head on the Set the position on the drilling machine, each time a hole is punched, then shake the dividing head to the position of the next hole and continue drilling until the entire hole is drilled. There are the following problems in adopting these punching methods: 1. It is necessary to pre-divide the bisector or shake t...
