The specific embodiment
A kind of super-long inner hole grinding tool of revolved body, as shown in Figure 1, comprise grinding unit, motor 10 and base 11, the grinding cell end is connected with motor 10 by shaft coupling 9, grinding unit and motor 10 are installed in respectively on the base 11, and the grinding unit comprises sleeve 7, mill bar axle 6 and emery wheel 2, and sleeve 7 is fixed on the base 11 by upper press cover 8, mill bar axle 6 is installed in the sleeve 7, and the tip position of mill bar axle 6 is installed emery wheel 2.
Emery wheel 2 closely is connected with mill bar axle 6 by round nut 1 and pressing plate 3, mill bar axle 6 is installed in the sleeve 7 by end mounted bearing 5 and end cap 4, sleeve 7 is clamped on the base 11 by upper press cover 8, the afterbody of mill bar axle 6 is connected with rubbercushioned sleeve bearing coupling 9 by key () 19, rubbercushioned sleeve bearing coupling 97 is connected with motor 10 by key (two) 20, motor 10 puts together on the base 11 by the lower margin hole, the handle that closes bolt and motor 10 footing by the handle that unclamps upper press cover 8 closes bolt, sleeve 7 and motor 10 can move axially on base 11 together, adjust the length of grinding unit protuberate basic unit 11, screw then closing bolt, to satisfy the requirement of different grinding lengths.
Set forth process below by specific embodiment:
Embodiment one
Add man-hour, as shown in Figure 2, penetrate in processing work 12 endoporus grinding rod sleeve tube 7 and being contained in this emery wheel 2 that grinds bar axle 6 terminations, carry out the finishing of emery wheel 2 with emery wheel 2 dressing tools that are fixed on the workpiece to be machined 12, the overall radial dimension of emery wheel 2 that is contained in these mill bar axle 6 terminations is greater than mill bar axle 6 sleeves 7, less than the diameter of bore of work piece, axial length that its mill bar axle 6 sleeves 7 the stretch out length greater than the required grinding of work piece position.Having the key () 19 of rotatable emery wheel 2 mill bar axles 6 by afterbody links with rubbercushioned sleeve bearing coupling 9, rubbercushioned sleeve bearing coupling 9 is driven by motor 10 by key (two) 20, thereby make emery wheel 2 rotations, whole super-long inner hole grinding tool of revolved body can put together on by four holes of base 11 bottoms on the middle slide carriage 17 of heavy horizontal lathe, by lathe big cargo chute 18 drive do vertical (axle) thus to the length of mobile grinding workpiece to be machined 12 endoporus, horizontal (directly) finished the diameter of grinding workpiece to be machined 12 endoporus by lathe middle slide carriage 17 to feeding.
Embodiment two
Can use a kind of truer that emery wheel 2 peripheries are repaired before the processing endoporus, as shown in Figure 3, this instrument comprises body 15, pinching screw 16 and diamond pen 14, and body 15 is the U font, and pinching screw 16 and diamond pen 14 are installed in the end, two ends of body 15 respectively.
At first processing work 12 clampings are held on the chuck of engine lathe and with carrying roller, super-long inner hole grinding tool of revolved body is fixed on the middle slide carriage 17 of lathe 13, again truer is fixed on the workpiece by the pinching screw on it 16, then the inner hole grinding unit is stretched in the endoporus of workpiece, utilize 14 pairs of emery wheel 2 cylindricals of diamond pen on the truer to repair, guarantee that emery wheel 2 cylindrical abrasive particles are sharp, unload truer at last, do radial motion (upper slitter) with lathe middle slide carriage 17, big cargo chute 18 axially moves (feeding), with super-long inner hole grinding tool of revolved body the endoporus of workpiece is carried out grinding.
