Description
Technical field
The present invention relates to the equipment of drying cylinder inner tube wall bore hole, a kind of boring machine for inner wall of drying drum by after repacking of ordinary lathe is particularly related to.
Background technology
At present for the Boring of large-scale drying cylinder inner tube wall it is relatively difficult, it is necessary to which special equipment, still, these special equipment prices are expensive, general producer can not purchase, if can now carry out bore hole on engine lathe, that will save many costs.The bore hole on engine lathe is achieved in that at present passes through special fixing equipment by drying cylinder（Such as outer centre frame）It is fixed on lathe, drying cylinder is rotated by the chuck of lathe, and knife rest bar is fixed with the active fulcrum bearing of lathe, and boring cutter is provided with the knife rest bar, active fulcrum bearing makes boring cutter bore hole on inner tube wall in the drive lower slider of secondary power set, this construction blade holder bar shakes knife aggravation into cantilever-shaped, not only, and moves back trend of pulling out and become big, make the precise decreasing of bore hole, and chuck drives drying cylinder to rotate, it is necessary to which aggressive device provides sufficiently large power output, causing the power consumption of lathe increases.
The content of the invention
The technical problems to be solved by the invention are：A kind of boring machine for inner wall of drying drum is provided, the equipment is under the improvement of original engine lathe, you can to select corresponding boring bar according to drying cylinder internal diameter and requirement on machining accuracy, the power output of main power plant can be reduced again, saved energy extension device service life.
In order to solve the above technical problems, the technical scheme is that：A kind of boring machine for inner wall of drying drum, including support, and it is installed on head and tailstock on support, the chuck driven by main power plant is installed on the head, thimble is installed on tailstock, the thimble is coaxially disposed with chuck, it is located on the support and active fulcrum bearing and driven fulcrum bearing is slidably fitted between head and tailstock, the active fulcrum bearing is driven by secondary power set and slided, fixed plate is installed in active fulcrum bearing and driven fulcrum bearing, the fastener of fixed drying cylinder is installed in the fixed plate, boring bar is installed between the chuck and thimble, one end of boring bar is installed on chuck, the other end is held out against by thimble, boring cutter component is installed on the boring bar.
It is used as a kind of preferred scheme, the fastener includes the first anchor ear and the second anchor ear, first anchor ear and the second anchor ear are provided with the arc banding face cooperated, the lower end of first anchor ear and the second anchor ear is mounted in fixed plate, and the upper end of first anchor ear and the second anchor ear can be connected by bolt buckle.
As a kind of preferred scheme, the lower end of first anchor ear and the second anchor ear and the mounting means of fixed plate are to be hinged.
Employ after above-mentioned technical proposal, effect of the invention is：Because this Boring machine fixes drying cylinder, and boring bar is installed between chuck and thimble, boring cutter is driven in drying cylinder inner tube wall bore hole operation using the rotation of boring bar, therefore, the moment of torsion of chuck output need to only ensure the rotation of boring bar, the power output of main power plant is reduced, energy consumption, extension device service life has been saved, in addition, boring bar bore hole process is not cantilever operation, and therefore, vibrations reduce, Boring preciseness is improved, and boring bar can be changed at any time, according to the different suitable boring bars of drying cylinder inner cylinder size selection, make the apparatus adaptability stronger.
Again because the fastener includes the first anchor ear and the second anchor ear, first anchor ear and the second anchor ear are provided with the arc banding face cooperated, the lower end of first anchor ear and the second anchor ear is mounted in fixed plate, the upper end of first anchor ear and the second anchor ear can be connected by bolt buckle, and the lower end of first anchor ear and the second anchor ear and the mounting means of fixed plate are to be hinged.Therefore, the first anchor ear and the second anchor ear can be rotated around jointed shaft, and the fixation of such drying cylinder more facilitates.
