As shown in Figure 4 and Figure 5, in the present embodiment, to 5 various sizes of unthreaded holes of preparatory processing the latter body cavity Edge carries out accurate 45 ° of chamferings, it is desirable that Glabrous thorn residual at chamfering.
The processing method of reversed chamfering the following steps are included:
Step 1: Work inspection device.Check the required precision of workpiece relative dimensions, appearance requirement simultaneously records.
Step 2: workpiece lumen spatial margin determines.
Before the unthreaded hole inner chamfer of processing different product inner cavity, the spatial margin size that need to be fully understood in product cavity is high H, width W, through-hole diameter D size are spent, chamfer dimesion requires and the requirement of finish roughness parameter, and then selects fitter type Number tip size and rotary speed parameter setting.
As shown in figure 5, in the present embodiment, to chamfered bore D1=10mm, D2=9mm, D3=8mm, D4=8mm, D5= 6mm.1,2,4 spatial margin height H=40mm of hole, width W=50mm;3 spatial margin height H=12mm of hole, width W= 40mm;5 spatial margin height H=8mm of hole, width W=8mm.All Hole chamfering angle=45 °;Decomposition data, set device add Engineering order parameter, and record data.
Step 3: the selection of reversed rose reamer.
Firstly, the shank diameter d of reversed rose reamer < diameter D to chamfered bore.The diameter of the width w of cutter head > to chamfered bore D, and < spatial margin width W.
Secondly, work as chamber intracorporal spatial margin dimensional height H > 15 millimeter, and the intracorporal spatial margin dimension width W of chamber > At 15 millimeters, the processing of reversed chamfering is carried out using the reversed rose reamer of cutter head locking type.
When chamber intracorporal spatial margin dimensional height H≤8 millimeter or the intracorporal milli of spatial margin dimension width W≤8 of chamber Meter Shi carries out the processing of reversed chamfering using the reversed rose reamer of bolt fixing type.
The processing for being all made of the reversed rose reamer of knife handle locking type and carrying out reversed chamfering to fall between.I.e. chamber is intracorporal Spatial margin dimensional height H > 8 millimeter, and the case where chamber intracorporal 15 >=W > 8 millimeter of spatial margin dimension width and cavity Interior spatial margin dimensional height 15 >=H > 8 millimeter, and the case where chamber intracorporal spatial margin dimension width W > 8 millimeter, it uses The reversed rose reamer of knife handle locking type carries out the processing of reversed chamfering.
In the present embodiment, cutter head w>10mm, the h<20mm of hole D1 are processed, spatial margin is big to be selected to use cutter head locking type anti- The processing of reversed chamfering is carried out to rose reamer.Process the cutter head w>9mm, h<25mm of hole D2;The big selection of spatial margin uses cutter head The reversed rose reamer of locking type carries out the processing of reversed chamfering.Process the cutter head w>8mm, h<10mm of hole D3;Spatial margin is little (8mm-15mm) selects the reversed rose reamer of knife handle locking type.Process the cutter head w>8mm, h<25mm of hole D4;Spatial margin is little, can Select the reversed rose reamer of knife handle locking type.Processing hole D5 is since spatial margin is too small (=8mm), cutter head w < 6mm;Select bolt solid The reversed rose reamer of fixed pattern.
