Special clamp for drilling phi 1 holes in pin blocks

Abstract

The invention relates to a special clamp for drilling phi 1 holes in pin blocks. The special clamp comprises a baseplate arranged on a workbench of a drilling machine, a vertical plate which is fixedly arranged by being vertical to the baseplate, an eccentric shaft mounted on the vertical plate, a drill bush mounted at the top of the vertical plate and a part clamping device, wherein a groove is arranged on the vertical plate, the part clamping device is placed in the groove, and the part of the drill bush, which extends out of the vertical plate, is opposite to the groove; and the part clamping device is mounted at the end part of the eccentric shaft. The clamp can complete drilling by clamping once, so that working efficiency is improved and drilling precision can be ensured.

Description

Technical field: [0001] The invention belongs to mechanical processing equipment, in particular to a special jig for drilling a φ1 hole with a pin block. 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, if the manual tailstock is used to drill holes on an ordinary lathe,...

AI Technical Summary

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.
