In spherical bearing seat processing

In spherical bearing processing ( Spherical bearing processing) : design and manufacture of the boring bar, to solve the problem in spherical bearing seat processing. Installed on a lathe, solved the production with general equipment and the key technology of the bearing. Tool rod 3 with shaft 4 devices in one long boring bar slot, boring bar 1 with three jaw chuck clamping and special top 15 bearing. Clip is 5 on the other side of the cutting tools by pin 2 connected with connecting rod (6). Connecting rod 6 at the other end through the pin shaft connected to the nut 8 7. Turn the screw 9 8 boring bar can make the nut 1 mobile in the dovetail groove. T20 1. 5 a left-handed screw 9 watts 10 hole in the rotation. Watts 10 from 16 fastening bolt in the boring bar 1 right end. Gear 11 m = 2 z = x = 31 - 0. 5 through the flat key 12 washer 13 14 fixed on the screw nut 9 right end. Boring bar 1 rotates, gear 11 special top 15 rotate. Top 15 milling with m = 2 z = 12 x = 0. 5 teeth, so gear rotates, 11 to 9 screw rotates, making silk mother 8 on the boring bar by pin 7 connecting rod 6 pin shaft drives the cutter bar 3 and 2, centered on shaft 4 bit 5 of the boring bar around long slot arc movement, thus accomplishes the processing within the sphere. With ordinary boring bar first boring? 164 on both sides of inner hole and end face, operation method: the workpiece fastening on the lathe big slide board. By using spherical boring boring bar 1 again. According to the machining allowance and ball face turning depth, determine the length of 5 out of the cutting tools, with screw fastening of the cutting tools. Slip board moved so that the workpiece center to align the center of shaft 4 tighten big slide plate. Turn head spindle are five axis four driving rotation from right to left, start cutting boring a knife after parking, shaking big slide plate to move artifacts operation lever, loosen the fastening screw, remove the cutting head, flipping over ( The knife before facing down) Again in the tool bar, and make out is equivalent to a certain depth of the turning of the cutting tools, tighten cutting head, to roll back the big slide plate fastening good, open the car, then start from left to right rotation of the cutting tools and cutting, repeated several times, until the processing to the appropriate size. In order to improve the surface quality. Recommended when rough boring. Tool main Angle f and vice are 45 ° Angle f1, point to grinding into fine boring with R95 R100 arc blade.
