Abstract

The invention belongs to the field of mechanical machining equipment, specifically relates to a tool for drilling an inclined hole in a circular plate-shaped part, and aims to solve the problems thatthe angle cannot be well controlled and clamping is not easy when the inclined hole is drilled in the side wall of the annular plate-shaped part. The tool comprises a workbench, a support base, a support plate and a drill sleeve guiding device. The support base is composed of a left support arm and a right support arm, a horizontal rotating shaft is connected to the top of the left support arm andthe top of the right support arm, and the support plate is inserted between the two support arms and is connected with a rotating shaft in a sleeve manner; the support plate comprises a bottom plate,a pressing plate and a positioning pin plate, the pressing plate is further provided with a two-force rod device, the support plate rotates around the horizontally-arranged rotating shaft to drive workpieces to pitch, and drilling at different oblique angles can be realized; the position of the positioning pin plate is changed so that the workpieces with different radii can be fixed, and radial runout of the workpieces during drilling can be prevented; the pressing plate restricts axial movement of the workpieces; the two-force bar device realizes restriction on rotation of the workpieces; and the drill sleeve guiding device can achieve accurate guiding of a drill bit for working.

Description

technical field [0001] The invention belongs to the field of mechanical processing equipment, and in particular relates to a tool for drilling oblique holes in circular plate-shaped parts. Background technique [0002] When processing mechanical parts, it is often necessary to drill inclined holes on the surface of mechanical parts. According to searches, some existing devices are only suitable for drilling inclined holes on a plane. If the drilling surface is an arc surface, such as for circular plate parts Drilling oblique holes on the outer wall surface of the workpiece not only needs to solve the problem of fixing the inclination angle, but also needs to be suitable for workpieces with different diameters and thicknesses, and solve the problems of axial movement, radial runout, and rotation of the workpiece during processing. The existing device It is impossible to solve the above problems at the same time. Contents of the invention [0003] The invention provides a t...
