Abstract
The utility model relates to a special fixture for an arc pen fork lathe groove, which comprises a ring flange, wherein a group of positioning components for mounting work pieces are uniformly mounted on the upper surface of the ring flange, and one pressure plate used for pressing a work piece and located above each positioning component is mounted on a flange plate which is on the side of each positioning component. The special fixture for the arc pen fork lathe groove is smart in design, reasonable in structure, convenient to use, strong in practicability and long in service life; and since the processing of a plurality of work pieces can be completely at one time, thereby greatly shortening the processing time and improving the working efficiency and the processing precision.
Description
Technical field
The utility model relates to the clamping device field, especially a kind of circular arc fork truck groove Special clamping device.
Background technology
Use in sewing machine circular arc pen fork surface need to process groove, usually adopt at present the milling machine working groove, though this mode is widely used, but still there is following defective in it: 1, because each clamping can only be processed a workpiece, want to process a plurality of workpiece, then need multiple clamping just can finish, therefore in process, have slow, the inefficient problem of process velocity, be not suitable for large-scale processing; 2, machining accuracy is low, and each dimensional accuracy of workpiece is difficult to guarantee.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of reasonable in design, simple in structure, easy to manufacture, circular arc fork truck groove Special clamping device that can improve working (machining) efficiency and machining accuracy is provided.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of circular arc fork truck groove Special clamping device, it is characterized in that: comprise a ring flange, one group of the uniform installation of the upper surface of this ring flange is used for installing the positioning component of workpiece, and a pressing plate that is used for workpiece pressing that is positioned at above the positioning component all is being installed on the ring flange of each positioning component side.
And, described positioning component is made of two alignment pin and detents that are formed on the ring flange upper surface that are installed on the ring flange, these two alignment pins and detent radially distribute from inside to outside, pressing plate is installed on two ring flanges between the alignment pin by screw, and this pressing plate is positioned at the top of two alignment pins.
And described positioning component is three.
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 a plurality of positioning components, so this device can grip a plurality of workpieces to be processed simultaneously, finishes simultaneously the recessing processing of a plurality of workpiece, thereby has greatly shortened process time, improved operating efficiency.
2, each positioning component top all is provided with a pressing plate, because this pressing plate can position workpiece, avoids workpiece to produce in process and rocks, and therefore uses this device can improve machining accuracy, and each dimensional accuracy of the part after the processing has all reached requirement.
3, positioning component is made of alignment pin and detent, and the front end of workpiece to be processed uses alignment pin to fix, and the detent location is used in the rear end, its good positioning effect, and stability is high, is conducive to equally improve machining accuracy.
4, this clamping device is that to adopt material be the iron plate of 45#, after design with the special fixture that rocking arm mills, the lathes such as surface grinding machine, line cutting are made, the service life that it has good anti-wear performance and extremely grows.
5, the utility model is an a kind of circular arc fork truck groove Special clamping device that designs ingenious, rational in infrastructure, easy to use, practical and long service life, owing to use this device once can finish the processing of a plurality of workpiece, therefore greatly shortened process time, improved operating efficiency and machining accuracy.

Fig. 1 is front view of the present utility model;
Fig. 2 is the top view (only illustrate one group of positioning component) of Fig. 1;
Fig. 3 is the rearview of Fig. 1.
The specific embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of circular arc fork truck groove Special clamping device comprises a ring flange 1, and three installing holes 7 are made at the back side of ring flange, and this installing hole is used for ring flange is installed in lathe.One group of positioning component that is used for installing workpiece of the uniform installation of the upper surface of this ring flange, positioning component quantity is not limit, and is generally three.A pressing plate 3 that is used for workpiece pressing that is positioned at above the positioning component all is being installed on the ring flange of each positioning component side.
Above-mentioned concrete mounting structure is: positioning component is made of two alignment pins 4 and a detent 5, alignment pin is installed on the ring flange, detent is formed on the upper surface of ring flange, these two alignment pins and detent radially distribute from inside to outside, and this alignment pin and detent are used for plug-in mounting workpiece 2.Pressing plate is installed on two ring flanges between the alignment pin by screw 6, and this pressing plate is positioned at the top of two alignment pins, so that compress from the top with the workpiece front end.
