The advantages are that: before the rig operation, when pressing from both sides the clamping part tight fixed, knob on the rotatory magnetic gauge stand makes its firm absorption on the workstation of rig, rig drive drilling rod downshifting in-process, it slides along the guide bar to drive the connecting block, when rig drive drilling rod drives antifriction bearing's inner circle and rotates, under the spacing of guide bar, antifriction bearing's outer lane and connecting block can not rotate, at this moment, can be through convenient the drilling position that sprays of coolant liquid that the cooling tube introduced, do not need manual operation, reduce intensity of labour, and the cooling efficiency is improved.
Description
The technical field is as follows:
the utility model relates to the technical field of machining, in particular to counter bore drill bit subassembly structure.
Background art:
in the mechanical processing process, drilling a structural member is a common processing procedure, and a drill bit is a tool which is necessary for drilling by a drilling machine; the counter bore drill bit is used for processing a counter bore, and the counter bore is designed on the structural member so that a screw cap of a screw is embedded into the structural member; in the process of processing the counter bore, the drill bit is heated due to friction, and the drill bit is easy to damage after long-time operation, so that the service life is influenced; in order to reduce the temperature of the drill bit in the machining process, the cooling liquid is squeezed into the drilling position by a plastic bottle filled with the cooling liquid manually, so that the labor intensity is high, and the efficiency is low.
The utility model has the following contents:
an object of the utility model is to provide a counter bore drill bit subassembly structure that is favorable to improving cooling efficiency and reduces intensity of labour.
The utility model discloses by following technical scheme implement: a counter bore drill bit assembly structure comprises a clamping part, a drill rod and a counter bore drill bit; the clamping part and the top end of the drill rod are coaxially and integrally formed, a blind hole is coaxially formed in the bottom end of the drill rod, and the counter bore drill bit is inserted into and welded and fixed in the blind hole; the drilling rod is sleeved with a rolling bearing, a connecting block is fixed to the outer ring of the rolling bearing, a guide rod is arranged on the connecting block in a penetrating mode and is parallel to the drilling rod, a magnetic gauge stand is fixed to the bottom end of the guide rod, and a cooling pipe with an outlet facing the counter bore drill bit is fixed to the connecting block.
Further, the cooling pipe is a universal bamboo joint pipe.
Furthermore, a linear bearing sleeved on the guide rod is fixed in the connecting block.
The utility model has the advantages that: before the drilling machine runs, the clamping part is clamped and fixed, meanwhile, the knob on the magnetic gauge stand is rotated to enable the knob to be firmly adsorbed on a workbench of the drilling machine, the drilling machine drives the drill rod to slide along the guide rod in the downward moving process, and meanwhile, the drill rod only drives the inner ring of the rolling bearing to rotate in the process that the drilling machine drives the drill rod to rotate; when the drilling machine drives the drill rod to drive the inner ring of the rolling bearing to rotate, the outer ring and the connecting block of the rolling bearing cannot rotate under the limiting of the guide rod, at the moment, the cooling liquid introduced through the cooling pipe can be conveniently sprayed to a drilling position, manual operation is not needed, the labor intensity is reduced, and the cooling efficiency is improved.
