Special fixture for drilling 2-phi1.5 hole on part

Abstract

The invention discloses a special fixture for drilling a 2-phi1.5 hole on a part, comprising a bottom plate, a vertical plate, a locating plate, a platen and a drill bushing, wherein the bottom plate is arranged on a drill workbench; the vertical plate is vertically and fixedly arranged with the bottom plate; the locating plate is arranged on the vertical plate; the platen is arranged on the side surface of the vertical plate; and the drill bushing is arranged between the platen and the locating plate. According to the fixture, a hole can be drilled by one-time clamping, working efficiency is improved, and drilling precision can be guaranteed.

Description

Technical field: [0001] The invention belongs to mechanical processing equipment, in particular to a special fixture for drilling 2-φ1.5 holes of parts. Background technique: [0002] In part processing, it is a very common processing method to use the drill template fixture to drill and tap the side or circumference of the part on the drill press. Drilling can be done on a special machine tool such as a drill press or a hexagonal lathe, or it can be drilled on an ordinary lathe with a hand-operated tailstock. Machining a part often requires multiple processes to complete, and the drilling process is mostly carried out after rough machining or semi-finishing, so drilling on a special machine tool such as a drilling machine or a hexagonal lathe requires repeated loading and unloading, alignment of the workpiece, and multiple stop and start. Machine tools, moving back and forth, consume more time. However, using a hand-operated tailstock to drill holes on a common lathe cons...

Problems solved by technology

Machining a part often requires multiple processes to complete, and the drilling process is mostly carried out after rough machining or semi-finishing, so drilling on a special machine tool such as a drilling machine or a hexagonal lathe requires repeated loading and unloading, alignment of the workpiece, and multiple stop and start. Machine tools, moving back and forth, consume more time

However, when drilling holes with a hand-operated tailstock on an ordinary lathe, it consumes a lot of energy and labor intensity is very high, it is difficult to accurately control the depth of the hole, and the production efficiency is not high.
