The specific embodiment
Following constipation closes the embodiment accompanying drawing, the specific embodiment of the present utility model is described in further detail, so that technical solutions of the utility model are easier to understand, grasp.
As shown in Figure 1, the related hole of the utility model processing unit (plant) is the ladder deep hole 1 that processing makes on the nonferrous materials, and b/a is greater than 30 for its draw ratio, and pore diameter range is between Φ 3mm-Φ 100mm.It has the oblique angle 13 (also can be circular arc) that plays a transition role between the first rank deep hole 11, the second rank deep hole 12 of different-diameter, different depth and two sections deep holes.Ladder deep hole at this generic request certain surface smoothness, circularity, axiality and linearity, traditional processing unit (plant) and technology thereof can't satisfy the required precision of processing, therefore design specific processing unit (plant), the honing that the non-ferrous metal workpiece carries out is step by step processed, just drawn the processing unit (plant) of a kind of big L/D ratio non-ferrous metal ladder deep hole of the present utility model.
As shown in Figure 2, the special feature of this processing unit (plant) 2 be to comprise by workpiece to be processed be transmitted wire-electrode cutting device 21, outer grinding equipment 22, self-centering collet 23 that direction sets gradually, mill reamer device 24 and in grinding equipment 25.Wherein:
Described wire-electrode cutting device 21 is used for the pre-hole of processing on the non-ferrous metal workpiece.The honing surplus is left in this pre-hole on workpiece, and with the main benchmark of this pre-hole as follow-up each procedure.For the consideration of the linearity and cost, adopt the first-selection of fast silk cutting machine in the utility model as wire-electrode cutting device.
The main effect of described outer grinding equipment 22 is based on the pre-hole processing excircles grinding machine of non-ferrous metal workpiece, and this cylindrical grinder obtains the first rank deep hole 11 that size, circularity, linearity and fineness satisfy required precision through honing processing.
Described self-centering collet 23 serves as location benchmark assembling with the first rank deep hole 11, improves the linearity and the axiality of follow-up honing processing operation with this.Be benchmark with this self-centering collet 23 earlier, cross-under is milled reamer device 24 and is processed counterbore, and this counterbore is to go deep into the stepped hole that pre-Kong Bingyu forms transition arc or oblique angle therebetween, is the blank of the second rank deep hole 12; Be benchmark with this self-centering collet 23 again, and be assist location that hone 25 carries out the counterbore honing in the cross-under, obtains the second rank deep hole 12 that size, circularity, linearity, fineness and axiality satisfy required precision to mill the counterbore that processes of hinge.
Especially, as shown in Figure 3, for overcoming non-ferrous metal honing furfur difficulty, the utility model grinding equipment outside reaches the auxiliary lead-in 3 that interior grinding equipment surface is equipped with anti-scraping.
