Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is done to further concrete detailed explanation.
As shown in the figure, a kind of aluminium lid cross grinding fixture for processing, comprise be provided with the chuck body 1 of screw thread locating hole and by identical two halfbodies at the synthetic tensioner tapered sleeve 3 with inner circle taper hole and external cylindrical surface of incision, the circumference of described external cylindrical surface is provided with the annular groove 5 that center line and tensioner tapered sleeve 3 center lines coincide.Described tensioner tapered sleeve 3 adds man-hour, inner circle taper hole and external cylindrical surface process in clamped one time, bipassage ring connected in star 5 on external cylindrical surface is processed as respectively the square groove of width and deep equality, in this detailed description of the invention, square groove is of a size of 1.5mm x 1.5mm, after the tensioner tapered sleeve 3 of entirety processes, this tensioner tapered sleeve 3 is cut into identical two halfbodies along the plane of crossing center line, place the wire loop 4 that the steel wire that is 1mm by diameter is made, described wire loop 4 has a fracture, one of them otch 6 between 3 two halfbodies of the fracture of described wire loop 4 and tensioner tapered sleeve is corresponding.
In tensioner tapered sleeve 3, be provided with and clamp mandrel 2, described clamping mandrel 2 is provided with that the conical section 8 matching with inner circle taper hole is connected with conical section 8 small ends and diameter is less than the cylindrical section 9 of inner circle taper hole end diameter, the end diameter of described conical section 8 is greater than the end diameter of inner circle taper hole, can avoid like this conical section 8 to be supported in chuck body 1, thereby ensure, during tensioner tapered sleeve 3 outside, be that tensioner tapered sleeve 3 contacts with the upper surface of chuck body 1 by workpiece to be processed gland.In this detailed description of the invention, because workpiece to be processed has a boss 12, so be provided with at the screw thread locating hole place of chuck body 1 counterbore matching with boss 12.The utility model, when only not having the workpiece of holes for clamping 13 with boss, can not have this counterbore.Described holes for clamping 13 can be the hole that on workpiece, itself just has, and can be also the fabrication hole of the special processing in order to use the utility model.
In order to reduce the contact-making surface of workpiece and chuck body 1 upper surface, further ensure the effect of clamping, can process some intervals and parallel groove 14 at chuck body 1 upper surface, described groove 14 can be linear, can be also arc.The setting of this groove 14 also can reduce the processing and fabricating cost to chuck body 1 upper surface itself.
Described cylindrical section 9 is provided with the external screw thread in order to match with the screw thread locating hole in chuck body 1, is provided with for clamping the driving section 7 of mandrel 2 precession chuck body 1 screw thread locating holes on the end face of the bigger diameter end of conical section 8.
Larger in order to make to screw power, hexagonal structure in described driving section 7 is used, further for better processing, can adopt the SOC.HD. cap screw of standard change a social system and obtain clamping mandrel 2, thereby can reprocess in addition interior hexagonal structure.This detailed description of the invention, clamps mandrel 2 and adopts the transformation of the way of M16 SOC.HD. cap screw to form.
When the utility model uses, the conical section that clamps mandrel 2 is coordinated with the inner circle taper hole of the tensioner tapered sleeve 3 of putting wire loop 4 well, then by downward tensioner tapered sleeve 3 taper hole small ends, upwards pack in holes for clamping 13 from the lower surface 11 of workpiece, again the cylindrical section 9 that clamps mandrel 2 is put into the screw thread locating hole of chuck body 1, using spanner to be inserted in driving section 7 from workpiece upper surface 10 by holes for clamping 13 again screws, in the process screwing, clamp mandrel 2 by tensioner tapered sleeve 3 and the outside spreading stretching workpiece of wire loop 4, it is clamped and is located.Then its upper surface 10 is processed.Completion of processing, unscrews and clamps mandrel 2, and wire loop 4 restores to the original state under the elastic force effect of himself, and tensioner tapered sleeve 3 is unclamped from the inwall of workpiece clamp tieholen 13.
Use the utility model, not only can effectively solve the clamping and positioning problem that aluminium lid cross grinding adds man-hour, and easy to operate, positioning precision is high, reliable clamping, has improved the grinding accuracy of aluminium lid cross grinding processing greatly, and has improved the efficiency that grinding is produced.
