Cylinder, the 3rd cylinder, the 4th cylinder, changeover portion, bullet and rod handle are set gradually from left to right, the 4th cylinder
Periphery is machined with external screw thread, and one end of bearing block is machined with blade installation slot, and the other end of bearing block is machined with bearing installation
Groove, and blade installation slot connected with bearing mounting groove, and back-up ring is arranged with adjusting nut, the side wall of adjusting nut is provided with spiral shell
Nail, ball-collecting rack bearing and adjusting nut are arranged in the bearing mounting groove of bearing block, and the periphery of back-up ring is stuck in bearing mounting groove
On the wall of side, and adjusting nut is threadedly coupled with the external screw thread of the 4th cylinder, and the end of thread of screw is withstood on the 4th cylinder, the
Blade dress hole is machined with two cylinders and the 3rd cylinder, blade is inserted into blade dress hole, and blade is arranged on blade
In mounting groove.
The beneficial effects of the invention are as follows：
1st, heat exchanger pore rounding instrument of the invention, solve lack in the prior art it is a kind of such as high plus, it is low plus
Deng heat-exchanger products tube sheet pore rounding equipment, compared with ordinary blade connection drilling machine processing mode, present invention processing rounding
The operating efficiency at angle improves 10-15 times.What is more important, using this instrument, the size and machining accuracy energy of work pieces process
Guarantee is accessed, while product quality is greatly enhanced, manufacturing cost is reduced.Simple in construction, low cost of the invention
It is honest and clean, it is easy to operate, and significantly reduce labor strength.Different lead is processed according to different pore aperture size designs
Post, this instrument is repeatable using multiple, reduces manufacturing cost.
