Description
Technical field
The utility model belongs to mechanical manufacturing technology, is related to a kind of drilling machine transmission arm for being used to process endoporus.
Background technology
In machine-building, some ring-shaped work pieces madial walls need counter boring.At present using the conventional anti-counterbit of combination.Divide four
Step completes counter boring：The first step, knife bar pass through the hole processed on part；Second step loads onto cutter head by hand；Third walks, by knife bar
Clamping is on drilling machine or milling machine；4th step, retaining element promote knife bar then up, complete counter boring.After the completion of counter boring, by hand
Cutter head is unloaded, exits knife bar.Repeat above operation the counter boring for carrying out next hole.The shortcomings that this method, is as follows：1st, because of zero
Part wall is thin, is susceptible to and allows knife phenomenon, counter boring size and surface roughness are not easy to ensure；2nd, part is not easy clamping；3rd, processing effect
Rate is low；4th, smaller in ring-shaped work pieces endoporus, handling cutter head is very inconvenient.
Invention content
The purpose of this utility model is：A kind of drilling machine transmission arm for being used to process endoporus is designed, for the part of processing
Mostly thin-walled parts, part wall thickness are 1mm~2mm, are needed from part madial wall counter boring.And ensure part processing quality, it improves
Processing efficiency.
The technical solution of the utility model is：It is a kind of for processing the drilling machine transmission arm of endoporus, which is characterized in that including the

Head (4)；First fastening semi-ring (1) is coupled, and first fastens semi-ring (1) and the with the second fastening semi-ring (8) by shaft rotation
Two fastening semi-rings (8) can be fixed on drilling machine；
Driven wheel (5) is rotatably arranged on support arm, and driven wheel is fixedly connected with drill bit, and realization rotates integrally；
Driving wheel (9) is provided with endoporus, is mutually fixed with drill press spindle by via；Driving wheel is passed by belt and driven wheel
It is dynamic.
Further, the driven wheel both sides are extended with axle journal, and two side shaft journals are rotatably supported by bearing
On support arm.
Further, support arm tool includes blank pipe cantilever and linking arm, and linking arm is used to fasten semi-ring or the with first
Two fastening semi-rings are fixedly connected；Driven wheel and belt are arranged in blank pipe cantilever, and support and protection are provided by blank pipe cantilever.
Further, the first fastening semi-ring and the second fastening semi-ring are tightened together by spiral or fixed pin.
Further, drill bit coordinates with driven wheel endoporus character, rotates integrally.
First fastening semi-ring (1) and the second fastening semi-ring (8) can be fixed on drilling machine shaft sleeve, workbench or drilling machine shell
On body；
Further, the first fastening semi-ring is interference fitted with shaft (7), and the second fastening semi-ring (8) is matched with shaft (7) gap
It closes, the second fastening semi-ring (8) can be freely rotated relative to the first fastening semi-ring (1).
The utility model has the advantages that：Have devised a kind of drilling machine transmission arm for being used to process endoporus, the fixture clamping side
Just, it is easy to ensure part counter boring quality, improves processing efficiency.One embodiment of the utility model, tests prove that, production
Efficiency improves 10 times or more.
