The cutter ring External Shape of shield machine is more complicated, and lathe or grinding machine add man-hour almost without periphery that can clamping, cause clamping location difficulty.Particularly grinding machine adds man-hour, the axiality in cutter ring interior step hole is required higher, and this just preferably requires to complete after clamped one time the Grinding Process of stepped hole.Though traditional grinding fixture can meet processing request, manufacturing procedure is many, and installing/dismounting is complicated, need to repeatedly adjust clamping process, to process, brings inconvenience.
Utility model content
The utility model is in order to solve weak point of the prior art, provides a kind of clamped one time can be by the whole grindings of shoulder hole in cutter ring and easy-disassembling-assembling shield structure cutter ring inner hole grinding frock clamp.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: shield structure cutter ring inner hole grinding frock clamp, comprise base plate, positioning core axle, double threaded screw and pressing plate, positioning core axle is located on base plate, the center line of positioning core axle is vertical with base plate to be arranged, positioning core axle is multidiameter structure, the external diameter that positioning core axle is positioned at base plate upper section is greater than the external diameter that is positioned at base plate below part, double threaded screw is provided with even number, all double threaded screws are all parallel with positioning core axle center line and circumferentially evenly arrange along positioning core axle center line, base plate is provided with the nut seat equating with double threaded screw number, each equal correspondence in double threaded screw lower end is threaded in nut seat, pressing plate is parallel with base plate, pressing plate is located on double threaded screw, double threaded screw upper end is threaded and is positioned at the clamp nut of pressing plate top, between clamp nut and pressing plate, be provided with the packing ring being enclosed within on double threaded screw, on pressing plate, offer the circular hole with the concentricity line of mandrel, pressing plate lower surface is provided with and is positioned at the positioning boss that circular hole outward flange is annular, pressing plate upper surface is provided with suspension ring.
Described double threaded screw lower end extend in base plate and is connected with base thread, the clamp nut being threaded on double threaded screw with the top interference fit of nut seat upper surface.
Described base plate is provided with the installing hole that is positioned at nut seat inner side, and installing hole is circumferentially evenly arranged along positioning core axle center line.
Adopt technique scheme, first base plate is placed on the workbench of vertical grinder, positioning core axle lower end is plugged in the groove on workbench, and uses bolt by installing hole, base plate to be fixedly installed on workbench.Back out clamp nut, use traveling crane to tangle the suspension ring on pressing plate, pressing plate is sling, re-using another driving is placed into cutter ring lifting on the base plate between double threaded screw, cutter ring compared with the endoporus of small end be placed on positioning core axle upper end and with positioning core axle matched in clearance, then pressing plate is installed on double threaded screw, positioning boss extend into the larger end endoporus of cutter ring matched in clearance, finally tightens clamp nut cutter ring is fixed.After clamping, can carry out grinding operation to cutter ring inner step hole.
The utility model is according to the processing request of shield machine cutter ring, manufacture a kind of frock clamp that can use on lathe and grinding machine, meet the demand of shield machine cutter ring grinding, easy installation and removal simultaneously, can effectively enhance productivity, guarantee the uniformity of product quality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, shield structure cutter ring inner hole grinding frock clamp of the present utility model, comprise base plate 1, positioning core axle 2, double threaded screw 3 and pressing plate 4, positioning core axle 2 is located on base plate 1, the setting vertical with base plate 1 of the center line of positioning core axle 2, positioning core axle 2 is multidiameter structure, the external diameter that positioning core axle 2 is positioned at base plate 1 upper section is greater than the external diameter that is positioned at base plate 1 below part, double threaded screw 3 is provided with even number, all double threaded screws 3 are all parallel with positioning core axle 2 center lines and circumferentially evenly arrange along positioning core axle 2 center lines, base plate 1 is provided with the nut seat 5 equating with double threaded screw 3 numbers, each double threaded screw 3 equal correspondence in lower end is threaded in nut seat 5, pressing plate 4 is parallel with base plate 1, pressing plate 4 is located on double threaded screw 3, double threaded screw 3 upper ends are threaded and are positioned at the clamp nut 6 of pressing plate 4 tops, between clamp nut 6 and pressing plate 4, be provided with the packing ring 7 being enclosed within on double threaded screw 3, on pressing plate 4, offer the circular hole 8 with the concentricity line of mandrel, pressing plate 4 lower surfaces are provided with and are positioned at the positioning boss 9 that circular hole 8 outward flanges are annular, pressing plate 4 upper surfaces are provided with suspension ring 10.
Double threaded screw 3 lower ends extend in base plate 1 and are threaded with base plate 1, can strengthen like this stability and the bonding strength of double threaded screw 3, the clamp nut 11 being threaded on double threaded screw 3 with nut seat 5 upper surface top interference fits.Adopt double threaded screw 3, this structure is convenient to dismounting and processing.
