Form moving pipe by moving pipe splined shaft, spline housing and interior pipe interlock short circuit and be installed in the motionless outer tube bore of forming by motionless outer tube loam cake, outer tube short circuit, spring housing, spline coupling cover and spline coupling cover lower cover.Second oil sealing, needle bearing and second thrust ball bearing on the interior pipe interlock short circuit cylindrical is in the inner chamber of spline coupling cover lower cover; The inner chamber that the inner ringless roller bearing on the moving pipe splined shaft cylindrical and first oil sealing are in spline coupling cover; Helical spring and stage clip on the moving pipe splined shaft cylindrical push away the inner chamber that fork is in spring housing; Braking slips tapering push rod on the moving pipe splined shaft cylindrical, first thrust ball bearing and moving pipe T type short circuit are in the inner chamber of motionless outer tube loam cake, and the outer tube braking slips on the moving pipe splined shaft cylindrical is between spring housing and the outer tube short circuit.
The single action three pipe bit tool outer tubes machinery slip-type check mechanism operating principle that the utility model provides is following:
When moving pipe splined shaft presses down; Moving pipe T type short circuit promotes first thrust ball bearing and moves down with braking slips tapering push rod; When being pushed to certain position, outer tube braking slips makes outer tube braking slips outwards eject under the extruding of braking slips tapering push rod; Make outer tube braking slips can be good to carry out the outer tube braking under the effect of the moving slips of control outside reliably with the rock contact.
When moving pipe splined shaft presses down the thrust elimination, utilize helical spring elastic force to make outer tube braking slips automatically reset, thereby the braking of removing outer tube promptly can be carried brill.
The utility model compared with prior art has following characteristics:
The mechanical slip-type outer tube check mechanism that the utility model provides when moving pipe splined shaft presses down, is released outer tube braking slips through the braking slips tapering push rod on the moving pipe splined shaft fast, and outer tube is braked reliably.
Further describe below in conjunction with accompanying drawing and the specific embodiment detailed structure the utility model.
