Abstract
The utility model relates to a special clamping device for grinding an outer arc of a crank component, which comprises a flange disc, wherein a group of positioning blocks for inserting work pieces are uniformly arranged on the upper surface of the flange disc, and a press plate used for positioning the work pieces and located above the positioning blocks is arranged on the flange disc. The special clamping device for grinding the outer arc of the crank component has the advantages of unique design, reasonable structure, convenience in use and good practicality. By adopting the device, the work pieces can be processed at a time, so that the processing time is shortened and the working efficiency is increased. In addition, the device is also high in processing precision, long in service life and suitable to be used in industrial production.
Description
Technical field
The utility model relates to the clamping positioning tool field, especially a kind of crank parts mill outer arc Special clamping device.
Background technology
Sewing machine crank needs to grind outer arc in process, the each clamping of conventional machining process can only be processed a workpiece, if want to process a plurality of workpiece, then need multiple clamping just can finish, therefore have in process that process velocity is slow, efficient is low, each dimensional accuracy is difficult to many defectives such as assurance.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of crank parts reasonable in design, simple in structure, easy to manufacture, that can improve working (machining) efficiency and machining accuracy to grind the outer arc Special clamping device.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of crank parts mill outer arc Special clamping device, it is characterized in that: comprise a ring flange, one group of locating piece that is used for the plug-in mounting workpiece of the uniform installation of the upper surface of this ring flange, the pressing plate that is used for positioning workpieces above one of ring flange installation is positioned at locating piece.
And, all make the alignment pin for the plug-in mounting workpiece on described each locating piece.
And described locating piece is four.
And three installing holes are made at the back side of described ring flange.
Advantage of the present utility model and beneficial effect are:
1, this clamping device is uniform on ring flange has installed one group of locating piece that is used for the plug-in mounting workpiece, so this device can grip a plurality of workpieces to be processed simultaneously, finishes simultaneously the mill outer arc processing of a plurality of workpiece, thereby has greatly improved working (machining) efficiency.
2, a pressing plate that is positioned at the locating piece top has been installed on the ring flange of this clamping device, this pressing plate can carry out compression set position, top to the workpiece that is installed on the locating piece, therefore use this device can improve machining accuracy, each dimensional accuracy of the part after the processing has all reached requirement.
3, this clamping device is that to adopt material be that the iron plate of 45# is made, and it has good wearability, can prolong the service life of this device.
4, the utility model is a kind of ingenious, rational in infrastructure, easy to use, practical crank parts mill outer arc Special clamping device that designs, and uses this device once can finish the processing of a plurality of workpiece, has shortened process time, has improved operating efficiency.In addition, this device has also that machining accuracy is high, long service life, the advantage such as is adapted at using in the suitability for industrialized production.
