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.

Embodiment Construction

[0013] As shown in the figure: a special jig for drilling 2-φ2.5 holes with a small bracket, consisting of a bottom plate 5 set on the drilling machine table, a backing plate 2 fixed to the bottom plate, a pressure plate 1 installed on the side of the bottom plate, and a drill sleeve 3 It is composed of a drill sleeve 8 installed on the top of the base plate. The installation position of the above-mentioned drill sleeve is opposite to the backing plate. The above-mentioned pressing plate is installed on the side of the bottom plate by adjusting the set screw 4 .

[0014] When using the present invention, the bottom plate is set on the workbench of the drilling machine, and then the parts 7 are fixed on the backing plate through the positioning pins 6, and the surfaces to be drilled are respectively opposite to the above two drill sleeves, and then the parts 7 are fixed on the backing plate through the adjustment of the pressing plate. The positioning screw 4 is clamped with a...

Abstract

The invention discloses a fixture special for a 2-phi2.5 hole of a small support drill. The fixture consists of a bottom plate arranged on a worktable of a drilling machine, a base plate fixed with the bottom plate, a platen arranged on one side of the bottom plate, a drill bushing and a drill bushing which is arranged on the top of the bottom plate. The fixture can finish drilling by one-time clamping, so that the work efficiency is improved and the accuracy of the drilling can be ensured.

Description

Technical field: [0001] The invention belongs to mechanical processing equipment, in particular to a special clamp for drilling 2-φ2.5 holes in a small bracket. 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...
