The specific embodiment
The special-purpose built-up jig of a kind of shaft key groove processing; At least comprise 2 groups of fixture units; Described fixture unit comprises V-shaped rest 1 and hold down gag 2; Described V-shaped rest 1 comprises: V-block backing plate 11 is provided with at least 1 pair of V-block 12 and feather key 15, and on V-block backing plate 11, is provided with the T type nut 13 and bolt 14 that is used for fixing V-shaped rest 1 on V-block backing plate 11; Described hold down gag 2 comprises: rotation cylinder pressure backing plate 21; On rotation cylinder pressure backing plate 21, be provided with at least 1 pair of rotation cylinder pressure 22, and on rotation cylinder pressure backing plate 21, be provided with and be used for fixing hold down gag 2 nuts 25 and T type bolts 24, on the piston rod of rotation cylinder pressure 22, be connected with briquetting 23; In the present embodiment; Built-up jig comprises 2 groups of fixture units, on V-block backing plate 11, is provided with 2 pairs of V-blocks 12, on rotation cylinder pressure backing plate 21, is provided with 2 pairs of rotation cylinder pressures 22.
For making content of the present invention more obviously understandable, further specify below in conjunction with the accompanying drawing and the specific embodiment.
In conjunction with Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the keyway processing special tooling anchor clamps of axial workpiece of the present invention comprise V-block, V-block backing plate, rotation cylinder pressure, rotation cylinder pressure briquetting, rotation cylinder pressure backing plate and feather key.V-block is fixed on the V-block backing plate; The rotation cylinder pressure is fixed on the rotation cylinder pressure backing plate; Rotation cylinder pressure briquetting is connected on the rotation cylinder pressure; The V-block backing plate all is fixed on the platen through T type slot bolt or T type groove nut with rotation cylinder pressure backing plate, and feather key is embedded in V-block backing plate lower surface and can slides along workbench T type groove, thereby can adjust the processing that two distances between the V-block backing plate adapt to different types of keyway easily like this.Add man-hour, axle is supported on the V-block, presses down through machine tool numerical control system control rotation cylinder pressure then to make axle fixing.
The V-block backing plate all is fixed on the platen through T type slot bolt or T type groove nut with rotation cylinder pressure backing plate; Feather key is embedded in V-block backing plate lower surface and can slides along workbench T type groove, thereby can adjust the processing that two distances between the V-block backing plate adapt to different types of keyway easily like this.Add man-hour, axle is supported on the V-block, presses down through machine tool numerical control system control rotation cylinder pressure then to make axle fixing.
As a kind of preferred implementation of the present invention; V-block is all fixed through the T type groove of backing plate and workbench with the rotation cylinder pressure; V-block all is fixed on the backing plate with the rotation cylinder pressure; Two V-blocks that support same axis must guarantee its center line on same straight line, and first assembling need check and adjust through instrumentation, adjusts the back and fixes.
As a kind of preferred implementation of the present invention; In order to adapt to different types of axle; Distance between two V-block backing plates can be adjusted; And when being supported on the different-diameter place of axle, we put into small cushion block and remain level with the axle center that guarantees axle on the V of V-block face, can guarantee the machining accuracy of keyway like this.
As an improvement of the present invention; Under the V-block backing plate feather key is installed, during bolt on unclamping the V-block backing plate, feather key can slide along T type groove; Slide into suitable apart from the time can directly tight a bolt; The center of two V-blocks of supporting same axis this moment and does not need to adjust once more still on same straight line, can practice thrift the time of assembling once more so greatly.
As an improvement of the present invention, the briquetting of cylinder pressure can extend, because the restriction of processed shaft size; When two cylinder pressures distance is too near; Interfere easily in the rotary course, adopt shorter briquetting this moment, and when two cylinder pressures distance is far away; We add contiguous block at the briquetting end increases its length, is connected through dogbolt between the two.
Shaft key groove processing special tooling of the present invention is when using; Should select the Support Position and guarantee that enough space mounting rotation cylinder pressure backing plates are arranged between two V-block backing plates; Because rotation cylinder pressure stroke is certain, so select suitable cushion block pad under rotation cylinder pressure backing plate, to make the rotation cylinder pressure can be pressed onto processed axle according to the size of axle.
When the axle confirming to process, we contrast this drawing, and selected its Support Position and rotation cylinder pressure depressed position are adjusted two distances between the V-block backing plate then and made it equal the distance between last two support levels of axle, tight a bolt.With four axles be put on the V-block face with V-block be benchmark to one side snap, the control panel control rotation cylinder pressure through Digit Control Machine Tool pressed down four axles was fixed on the V-block this moment.The controlled pressure of rotation cylinder pressure can obtain optimal value through finite element analysis software, also can obtain through the method for experiment.Control rotation cylinder pressure lifts so that take out the axle that machines after keyway machines, and waits for processing next time.The case of practical implementation described in the present invention is merely preferable case study on implementation of the present invention, is not to be used for limiting practical range of the present invention.Be that all equivalences of doing according to the content of claim of the present invention change and modification, all should be as technological category of the present invention.
