Abstract
The utility model relates to an adjustable fixture for an above-3MW (Megawatt) wind turbine torsion shaft. The adjustable fixture comprises a fixture main body and a supporting plate perpendicular to the fixture main body. A clamping mouth which is used for clamping a workpiece is arranged at the top end of the supporting plate. A hexagon socket screw which is used for aligning the workpiece is arranged at the clamping mouth. Long holes are arranged in the fixture main body. Bolts penetrate through the long holes to tightly fix the fixture on a worktable. Bolt holes are additionally arranged on the fixture main body. A pressing plate tightly presses the workpiece through the bolt holes. Rib plates which take an effect of reinforcing the supporting plate are additionally arranged on the fixture. By using the adjustable fixture for the above-3MW wind turbine torsion shaft, not only can the problem that the wind turbine torsion shaft is required to be clamped and aligned for multiple times because a digital display boring worktable is short when a central hole is punched in the wind turbine torsion shaft be solved, the one-step clamping for processing be realized, the production efficiency be improved, and the requirements on size precision and position tolerance are better satisfied.
Description
Technical field
The utility model relates to a kind of processing of wind power product blower fan torsional axis, the flexible jig of using when relating in particular to blower fan torsional axis centering.
Background technology
Along with the exhaustion day by day of traditional energy and day by day increasing the weight of of environmental pollution, wind energy more and more is subject to people's attention as a kind of green energy resource.In order to develop better and develop wind power product, country has provided a lot of favourable policies, and purpose will encourage enterprise to draw close to Wind Power Generation Industry exactly, produces energy saving and environment friendly product, when revitalizing and developing national industry, further develops novel industry.Country encourages the dynamics of new energy development constantly to strengthen, and impels various energy products to emerge in an endless stream.
The blower fan torsional axis is a vitals in wind power product, in the mechanical processing process of blower fan torsional axis centering, because the workbench of digital display boring is shorter, need multiple clamping, centering in the process of centering, workpiece loading and unloading bothers very much, and versatility is poor, can not complete disposable processing, and this has reduced the efficient of manufacturing to a great extent.
Summary of the invention
Be the above-mentioned problem that needs multiple clamping, centering that runs in the mechanical processing process that solves the blower fan torsional axis centering in present wind power product, the applicant designs a kind of fixture of blower fan torsional axis centering, and namely 3 megawatts are with fan torsional axis flexible jig.
The technical scheme that its technical problem that solves the utility model adopts is:
3 megawatts are with fan torsional axis flexible jig, comprise jig main body and perpendicular to the gripper shoe of jig main body, and the gripper shoe top has the jaws for place work piece, and clamp mouth part arranges the hexagon socket head cap screw that workpiece is carried out centering; Have slotted hole on jig main body, bolt by slotted hole with this fixture tightly on workbench, bolt hole also is set on jig main body, pressing plate by bolt hole with Work-sheet pressing; Also arrange on fixture gripper shoe is worked the gusset of strengthening supporting role.
When the jaws of described hexagon socket head cap screw self-supporting slab is stretched in jaws, when all being placed with hexagon socket head cap screw at the bottom of two contained sides of jaws and jaws, result of use is better.
During use, with bolt by slotted hole with jig main body tightly on workbench, then workpiece is placed on the jaws on gripper shoe top, be placed with hexagon socket head cap screw at the bottom of the contained side by being adjusted at jaws and recess; Workpiece is carried out centering; Again by bolt hole with pressing plate with Work-sheet pressing, guarantee that workpiece reverses end for end in process clamping, centering again again.Gusset is set plays the reinforcement supporting role.In the Practical manufacturing process, use simultaneously two fixtures can produce better effect.
The beneficial effects of the utility model are: by using the utility model, not only solved the aobvious boring workbench of factor shorter and cause a difficult problem that needs multiple clamping, centering in blower fan torsional axis centering process, can complete disposable clamping processing, improve production efficiency, and guaranteed better dimensional accuracy and position of related features requirement.Simultaneously, this utility model is installed, convenient disassembly, can manual adjustments, and flexibility is very good.
Description of drawings
The utility model has accompanying drawing 3 width.
Fig. 1 is that the utility model master looks schematic diagram,
Fig. 2 is the utility model schematic top plan view,
Fig. 3 is that the utility model uses view.
In the drawings: 1, jig main body, 2, gripper shoe, 3, jaws, 4, workpiece, 5, hexagon socket head cap screw, 6, contained side, 7, contained side, 8, at the bottom of jaws, 9, slotted hole, 10, bolt hole, 11, gusset.
The specific embodiment
Illustrate the utility model below in conjunction with embodiment.
A kind of 3 megawatts as shown in Fig. 1 ~ 3 are with fan torsional axis flexible jig, comprise jig main body 1 and perpendicular to the gripper shoe 2 of jig main body, gripper shoe 2 tops have the jaws 3 for place work piece, and jaws 3 places arrange the hexagon socket head cap screw 5 that workpiece 4 is carried out centering; Have slotted hole 9 on jig main body 1, bolt by slotted hole 9 with this fixture tightly on workbench, bolt hole 10 also is set on jig main body 1, pressing plate compresses workpiece 4 by bolt hole 10; Also arrange on fixture 2 gussets 11 of strengthening supporting role of gripper shoe.
As better embodiment of the present utility model, the jaws 3 of described hexagon socket head cap screw 5 self-supporting slabs 2 is stretched in jaws 3, two contained sides 6 of jaws 3,7 and jaws at the bottom of 8 all be placed with hexagon socket head cap screw.
During use, with bolt by slotted hole with jig main body tightly on workbench, then workpiece is placed on the jaws on gripper shoe top, be placed with hexagon socket head cap screw at the bottom of the contained side by being adjusted at jaws and recess; Workpiece is carried out centering; Again by bolt hole with pressing plate with Work-sheet pressing, guarantee that workpiece reverses end for end in process clamping, centering again again.Gusset is set plays the reinforcement supporting role.In the Practical manufacturing process, use simultaneously two fixtures can produce better effect.
By using the utility model, manually to adjust hexagon socket head cap screw and just can carry out centering to workpiece, convenient processing is raised the efficiency and machining accuracy, can realize that disposable clamping completes this operation.And this frock facilitates the clamping location of torsional axis, can guarantee better stability and security in process.
Through facts have proved, remarkable with this its effect of centre bore of installing the blower fan torsional axis of having processed, have process technology reliable, process is stable, and practical, high reliability has guaranteed the quality of production of this product well, finally, reach client's satisfaction.
The utility model is not limited to above-described embodiment, and protection domain of the present utility model is all classified in any equivalent concepts or change in the technical scope that the utility model discloses as.
