Abstract
The utility model discloses a cutting head exchangeable thin plate drilling bit, which includes a cutting head, a drilling handle. A center water guide hole is provided in the drilling handle. A water cooling hole and the water outlet are provided in the cutting head. The cutting head is connected with one end of the drilling handle by thread. The water cooling hole on the cutting head is simultaneously connected with the water guide hole in the drilling handle. The other end of the drilling handle is connected with the drilling machine power outlet. Since the cutting head and the drilling handle are connected in a demountable mode, the completely corrosion cutting head can be demounted from the drilling head. The new cutting head can be replaced and the drilling handle can still continuously be used, therefore, the utility model can reduce the operation cost effectively.

The utility model content
At the defective that prior art exists, the purpose of this utility model provides a kind of by cutting head and drillstock are removably connected, thereby makes the removable Thin board drilling bit of cutting head.
For achieving the above object, the Thin board drilling bit of the utility model replaceable cutting head comprises cutting head, drillstock, be provided with the center water-guiding hole in the drillstock, be processed with cooling water hole and delivery port on the cutting head, cutting head links to each other with drillstock one end threadably, the cooling water hole while on it is communicated with the water-guiding hole on the drillstock, and the drillstock other end links to each other with rig power delivery.
Further, cooling water outlet is eccentrically set on the cutting head bottom surface on the described cutting head.
Further, the described drillstock end that links to each other with rig is taper, links to each other with rig power delivery by this taper.
Further, the described drillstock end that links to each other with rig has external screw thread, links to each other with rig power delivery by this external screw thread.
Further, also be provided with locking nut on the described drillstock.
Further, link to each other with the rig end of an end of described drillstock is provided with shoulder, be set with a fixed cover on the drillstock, this fixed cover outer surface is processed with external screw thread and for the be installed rotation fastening structure of usefulness of instruments such as spanner, drillstock one end is pressed solidly in the threaded mounting hole that on rig power delivery, is provided with by this fixed cover, at drillstock with when rig power delivery links to each other, radial location face by being provided with in the threaded mounting hole on described fixed cover or the rig power delivery makes drillstock concentric with the power delivery.
Further, cutting functor in second road is set also on the described drillstock, has suitable spacing between this cutting functor and the cutting head, effective radius of clean-up of described second road cutting functor is greater than effective radius of clean-up of described cutting head.
Further, be set with one on the described drillstock for being connected with rig power delivery with screw thread pressure mother, this screw thread presses female shoulder that is provided with by the drillstock end to be limited on the drillstock, its outer surface is processed with rotation fastening structure, press mother by its internal thread and when rig power delivery links to each other at screw thread, drillstock one end is pressed solidly with one heart on rig power delivery end face.
Further, described screw thread presses generatrix to be provided with second road cutting functor to the first end of described cutting, have suitable spacing between this cutting functor and the cutting head, effective radius of clean-up of described second road cutting functor is greater than effective radius of clean-up of described cutting head.
After cutting head and drillstock be arranged to the mode of removably connecting, when cutting head by after the wearing and tearing fully, it can be unloaded from drillstock, change new cutting head again, and drillstock continues still to use, so the utility model can effectively reduce construction cost.
