Abstract

A special fixture for machining a fan hub comprises a fixture body, a plate pressing mechanism and a positioning mechanism. The four corners of the upper surface of the fixture body are respectively provided with a thread hole, and the plate pressing mechanism is mounted on the thread holes of the fixture body. The positioning mechanism is arranged in the middle of the upper surface of the fixture body, and the positioning mechanism comprises two sets of positioning stopping blocks which are arranged in a crisscross shape. Each set of positioning stopping blocks comprises one fixed positioning stopping block and one sliding positioning stopping block, and the sliding positioning stopping blocks can freely rotate relative to the fixed positioning stopping blocks. The special fixture for machining the fan hub has the advantages that the structure is simple, hubs with complex shapes and mechanisms can be clamped, the production efficiency is high, and production needs are met.

Description

A kind of special fixture for axial fan hub processing

Technical field

The utility model relates to Machining Technology field, especially a kind of special fixture for axial fan hub processing.

Background technology

Axial fan hub is the important spare part of blower fan, directly has influence on performance and the service life of blower fan, and the wheel hub that therefore processes superior performance uses and has important value blower fan.But due to the complex structure of axial fan hub, as shown in Figure 1, axial fan hub has circular hole face and elliptical aperture face.In the time of processing, clamping is very difficult, when existing axial fan hub fixture clamping wheel hub, not to its positioned internal, very easily causes machining deformation, reduces wheel hub machining accuracy.As Chinese patent " a kind of rotating jig for wind power hub (patent No.: 201120469929.0) " arranges wind power hub fixed block at rotation seat upper surface in middle wind-powered electricity generation fixing device for wheel hub, fixed block is unadjustable, can not meet the not clamping processing of coplanar of wheel hub.

Utility model content

In order to overcome above-mentioned technical problem, the utility model provides a kind of special fixture for axial fan hub processing.

The technical scheme in the invention for solving the technical problem is: a kind of special fixture for axial fan hub processing, comprise jig main body, press plate mechanism and detent mechanism, it is characterized in that, four bights of described jig main body upper surface are respectively equipped with a screwed hole, described press plate mechanism is installed on the screwed hole place of jig main body, described jig main body upper surface middle part is furnished with detent mechanism, described detent mechanism is two groups of position blocks that across is arranged, every group of position block comprises a fixed position block and a slip position block, slip position block can be free to slide with respect to fixed position block.

Further, described press plate mechanism comprises threaded rod, pressing plate and nut, and described threaded rod is installed on the screwed hole place, four bights of jig main body upper surface, and described pressing plate is set on threaded rod and in pressing plate upper end and is screwed with nut.

Further, described detent mechanism is two groups of position blocks, every group of position block comprises a fixed position block and a slip position block, described fixed position block is fixedly installed on jig main body, described slip position block is installed on jig main body by leading screw, described leading screw is installed in the chute that jig main body upper surface offers, and described leading screw two ends are fixed by bearing.

Further, described jig main body upper surface offers the chute for slip position block is installed, and described chute one end is provided with the through hole that connects jig main body, and the described chute other end is provided with for bearings mounted blind hole.

The beneficial effects of the utility model: adopt after said structure, the utility model is by regulating the distance of two slip position blocks with respect to each self-corresponding fixed position block, be used for locating each face of axial fan hub, the utility model is simple in structure, not only can realize the wheel hub clamping to shape mechanism complexity, and production efficiency is higher, has met need of production.
