Embodiment

[0035] Irregular shape parts to be processed 4 such as figure 1 , 2 , as shown in 3, for figure 1 , 2 3. For cast aluminum parts with extremely irregular shapes as shown in 3, especially a tapered hole is processed in the middle of the part, and a tapered annular spiral oil groove is processed in the hole. The precision and surface roughness of the tapered hole are very high. The feature of the tapered annular spiral oil groove must be processed on a CNC lathe, and the traditional three-jaw or four-jaw chuck on a CNC lathe cannot meet the clamping requirements at all.

[0036] like Figure 4 , Figure 5 As shown, a fixture for CNC lathe processing parts with irregular shapes, including a supporting part, a positioning part and a fixing part, the supporting part includes a supporting base 1, a supporting plate 5 and a supporting panel 7, and the positioning part includes a positioning pin 2 and a shaft Shoulder positioning screw 3, the fixed parts include locking bolt 6 an...

Abstract

The invention relates to a clamp used for a numerical control lathe for machining parts in irregular shapes. The clamp comprises a supporting part, a positioning part and a fixing part; the supportingpart comprises a supporting base, supporting plates and a supporting panel, the positioning part comprises a shaft shoulder positioning screw, the fixing part comprises a locking bolt and a fixing nut, the two supporting plates are arranged, the left supporting plate and the right supporting plate are vertically placed on the supporting base, the supporting panel is arranged on the left supporting plate and the right supporting plate, the locking bolt fixes the supporting panel and the left and right supporting plate to the supporting base from top to bottom, the parts to be machined and in irregular shapes are positioned on the supporting panel through the shaft shoulder positioning screw, and are fixed through the fixing bolt, and the supporting base is of an external circle step structure and is used for being directly fixed to a three-claw chuck of the numerical control lathe. Compared with the prior art, the clamp has the advantages of being simple in structure, wide in application range, high in positioning precision, high in generality, long in service life and the like.

Description

technical field [0001] The invention relates to a fixture, in particular to a fixture for machining irregular-shaped parts with a numerical control lathe. Background technique [0002] At present, CNC lathes are basically equipped with three-jaw or four-jaw chucks, which can only process round, triangular, hexagonal or square materials. For parts with irregular shapes, the current three-jaw or four-jaw chucks cannot be directly clamped at all. [0003] For cast aluminum parts with extremely irregular shapes, especially a conical hole is processed in the middle of the part, and a tapered annular spiral oil groove is processed in the hole. The characteristics of the oil groove must be processed on a CNC lathe, and the traditional three-jaw or four-jaw chuck on a CNC lathe cannot meet the clamping requirements at all. Therefore, it is urgent to develop a fixture for machining irregular shape parts on a CNC lathe. [0004] Chinese patent CN202607301U discloses a fixture for pr...
