The clamping device of carbon bar curved face processing
Technical field
The utility model relates to technical field of tooling clamps, particularly relates to a kind of frock clamp of carbon bar curved face processing.
Background technology
Carbon slipper is the necessity that high ferro is run, and run hourly velocity due to high ferro and be exceedingly fast, therefore, in the manufacture process of carbon slipper, links all can not be made mistakes easily, when especially processing carbon slipper carbon bar.Along with the expansion of carbon slipper range of application, sometimes need to process cambered surface and fluting on the carbon bar of carbon slipper, but in prior art, also only do not need clamped one time carbon bar can carry out the special fixture of cambered surface and fluting processing on carbon bar.
Summary of the invention
The purpose of this utility model is exactly to overcome above-mentioned the deficiencies in the prior art, a kind of clamping device of carbon bar curved face processing is provided, its structure is simple, clamping carbon bar is easy, quick, only need carry out milling arc that clamped one time just can complete carbon bar with slotting to carbon bar to process, guarantee precision when large curved face processing carries out to carbon bar, ensure cambered surface and the uniformity of processing of slotting.
For realizing above-mentioned purpose of the present utility model, the clamping device of carbon bar curved face processing of the present utility model comprises: for settling the fixed block treating the carbon bar of curved face processing thereon; For carbon bar being positioned the positioning component on described fixed block; Wherein, described fixed block has the medial surface for contacting with the lateral surface of described carbon bar.
Wherein, the medial surface of described fixed block comprises vertical plane.
Wherein, arrange L shape groove inside described fixed block, described carbon bar is placed in L shape groove.
Wherein, described positioning component comprises: to be placed in above described fixed block and to have the pressing plate of the compressed part contacted with described carbon bar upper surface; For pressing plate being anchored on the clamping screw on described fixed block.
Wherein, described fixed block is detachably installed on the workbench of milling machine.
Compared with prior art, the clamping device tool of carbon bar curved face processing of the present utility model has the following advantages: structure is simple, clamping carbon bar is easy, quick, only need carry out milling arc that clamped one time just can complete carbon bar with slotting to carbon bar to process, guarantee precision when large curved face processing carries out to carbon bar, ensure cambered surface and the uniformity of processing of slotting.
Below in conjunction with accompanying drawing, the utility model is described in detail.

Detailed description of the invention
As shown in Figure 1 and Figure 2, for front view and the right view of curved face processing carbon bar are treated in clamping device clamping of the present utility model, as seen from the figure, this clamping device comprises: for settling the fixed block 1 treating the carbon bar 4 of curved face processing thereon; For carbon bar 4 being positioned the positioning component on fixed block 1; Wherein, fixed block 1 has the medial surface for contacting with the lateral surface of carbon bar 4.
Wherein, as shown in Figure 2, fixed block 1 comprise vertical plane for the medial surface contacted with the lateral surface of carbon bar 4.Preferably, arrange L shape groove in the inner side of fixed block 1, this L shape groove comprises vertical plane and horizontal plane (as shown in Figure 2), and treats that the carbon bar 4 of curved face processing is placed in L shape groove.
Wherein, as shown in Figure 1 and Figure 2, positioning component of the present utility model comprises: be placed in the pressing plate 2 above fixed block 1, and it has the upper surface stretching out in fixed block 1 and the compressed part contacted with the upper surface of carbon bar 4; For pressing plate 2 being anchored on the clamping screw 3 on fixed block 1.Accordingly, fixed block 1 arranges the screwed hole matched with clamping screw 3, by mode clamping screw 3 being screwed into fixed block 1, pressing plate 1 is installed on fixed block 1, carbon bar 4 is compressed by the compressed part of pressing plate 1.Preferably, pad can also be adopted between clamping screw 3 and pressing plate 2.
Wherein, fixed block 1 of the present utility model is installed on the workbench of milling machine by removably, and such as, the mode be bolted is installed on workbench.
Adopt clamping device of the present utility model can clamp carbon bar 4 as shown in Figure 3, this carbon bar 4 is in cuboid, before needs carry out curved face processing to carbon bar 4 as shown in Figure 3, first adjust the depth of parallelism of clamping device datum level and milling machine table mobile alignment, then carbon bar 4 is clamped on clamping device, the lateral surface of carbon bar 4 is made to be tight against on the medial surface of fixed block 1, adjust the PLC program of carbon bar being carried out to curved face processing and fluting on CNC milling machine, recycling milling arc cutter carries out the processing of default radian at carbon bar 4 medial surface, add man-hour, length direction along carbon bar 4 is processed from its one end towards the other end, and after radian machines, milling arc cutter is pulled down by the pneumatic knife-changing system of CNC milling machine, change T-slot dedicated tool, fluting processing is carried out to the carbon bar 4 processing radian, add man-hour, the length direction along carbon bar 4 is processed from its other end towards one end (that is, completes radian processing in process, fluting processing is completed in backhaul), carbon bar 4 to be processed into the carbon bar 4 ' with cambered surface and groove as shown in Figure 4, Figure 5.
To sum up, clamping device tool of the present utility model has the following advantages: structure is simple, when to carbon bar cambered surface and slot machining, clamping carbon bar is easy, quick, and, only need carry out to carbon bar the milling arc that clamped one time just can complete carbon bar process with fluting, guarantee precision when large curved face processing carries out to carbon bar, ensure the uniformity that cambered surface and fluting are processed.
Although be explained in detail the utility model above; but the utility model is not limited thereto; those skilled in the art can modify according to principle of the present utility model; therefore, all various amendments carried out according to principle of the present utility model all should be understood to fall into protection domain of the present utility model.
