Abstract

The invention relates to a special fixture for a lifting lug, which comprises a backing plate, a cylindrical positioning pin and a trimming positioning pin. The cylindrical positioning pin and the trimming positioning pin are respectively arranged on the backing plate, a bottom plate is arranged at the bottom of the backing plate, the bottom plate, the backing plate, the cylindrical positioning pin and the trimming positioning pin are of an integral structure, and a positioning hole is arranged on the bottom plate. The special fixture for the lifting lug is designed into the integral structure, so that clamping speed is greatly increased, realignment is not needed in batch production, layered machining is omitted, chamfering is uniform, production efficiency is improved, machining precision is ensured, and the special fixture can be used for machining other similar workpieces and has certain universality.

Description

A kind of hanger special fixture
Technical field
The present invention relates to a kind of anchor clamps, relate in particular to a kind of digital control processing hanger special fixture that is used for, belong to the component of machine technical field.
Background technology
Require chamfering 2mm * 45 ° during CNC milling machine processing hanger part, other operations of workpiece are accomplished, and two big faces process, and two holes boring processing finish external arc surplus 2~3mm.Require peripheral circular arc of processing and chamfering on the CNC milling machine, the clamping in circular arc limit can machine, but chamfering needs positive and negative twice clamping just can accomplish.The positive and negative chamfering requires uniformity, in process, can exist, and there is inconvenience in workpiece when centering; Workpiece can only position clamping with centre bore; And two hole lines of centres of levelling are more time-consuming, bothersome, especially when producing in batches, this defective is more obvious.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed a kind of can make workpiece simply, the hanger special fixture of positioning and clamping fast and accurately.
Technical solution of the present invention is achieved in that a kind of hanger special fixture, comprises backing plate, cylinder alignment pin, chamfered edge alignment pin, and said cylinder alignment pin, chamfered edge alignment pin are separately positioned on the backing plate, and said backing plate bottom is provided with base plate; Said base plate, backing plate, cylinder alignment pin, pin limit alignment pin are the integral type overall structure; Have locating hole on the said base plate.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
The present invention program's hanger special fixture is that the overall structure of integral type has greatly improved clamping speed with jig Design, does not need centering again when producing in batches; Process without layering; Chamfering is even, has improved production efficiency, and machining accuracy has also had assurance simultaneously; Also can be used in other similar workpiece processing, have certain versatility.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Accompanying drawing 1 is the three-dimensional structure diagram of a kind of hanger special fixture of the present invention;
Accompanying drawing 2 is the user mode figure of a kind of special fixture of hanger of the present invention;
Wherein: 1, base plate; 2, backing plate; 3, cylinder alignment pin; 4, chamfered edge alignment pin; 5, opening pressing plate; 6, nut; 7, workpiece; 8, installing hole.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done further detailed description.
Accompanying drawing 1,2 is a kind of hanger special fixture of the present invention, comprises backing plate 2, cylinder alignment pin 3, chamfered edge alignment pin 4, and said cylinder alignment pin 3, chamfered edge alignment pin 4 are separately positioned on the backing plate 2, and the bottom of said backing plate 2 is provided with base plate 1; Said base plate 1, backing plate 2, cylinder alignment pin 3, pin limit alignment pin 4 are the integral type overall structure; Have installing hole 8 on the said base plate 1.Digit Control Machine Tool is when processing work; Workpiece 7 is placed on the backing plate 2; Two locating holes of workpiece 7 are enclosed within respectively according on the cylinder alignment pin 3 of the locating hole size design of workpiece 7 and the chamfered edge alignment pin 4; Make on its workpiece pressing 7 with nut 6 lock opening pressing plates 5 again, make workpiece 7 Fast Installation location.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
The present invention program's hanger special fixture is that the overall structure of integral type has greatly improved clamping speed with jig Design, does not need centering again when producing in batches; Process without layering; Chamfering is even, has improved production efficiency, and machining accuracy has also had assurance simultaneously; Also can be used in other similar workpiece processing, have certain versatility.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
