Abstract
The utility model relates to a kind of numerically controlled lathe circular arc blind hole chit drill forming processing devices for realizing numerically controlled lathe circular arc blind hole segmentation chit drill processing and forming, including chit drill, the chit drill cutter hub of chit drill is installed, the knife bar of chit drill cutter hub being connected on numerically-controlled machine tool rest by cutting tool arbor for CNC machine tool seat is installed, the knife bar is eccentric knife bar, chit drill cutter hub is connected on eccentric knife bar by tailing screw flight, realize 2.5 meters of 300 depth of diameter of phi 200- Φ or more circular arc blind hole chit drill processing and forming, chit drill processing and forming can effectively be controlled and connect depth dimensions and diameter dimension at knife, it is high to control precision accuracy, improve the processing quality of product.
Description
Technical field
The utility model belongs to numerically controlled lathe forming processing technology field more particularly to a kind of realization numerically controlled lathe circular arc is blind
The numerically controlled lathe circular arc blind hole chit drill forming processing device of hole segmentation chit drill processing and forming.
Background technique
Currently, when processing the processing of blind hole inner hole bottom circular arc of diameter of phi 200- Φ 300mm, 2.5 meters of depth or more,
Generally use deep hole drilling and boring machine and process inner hole boring in the way of forming flat drill at after stepped hole, i.e., forming flat drill be designed as with it is blind
The identical integrally formed cutter of hole bore circular arc shape, after forming flat drill is coupled with boring cutter body and drilling rod, in deep hole drilling and boring machine
On processed.When processing the blind hole inner hole bottom larger arc of diameter of phi 200- Φ 300mm, 2.5 meters of depth or more, usually
It takes and chit drill is divided into several sections of split type processing, it is big using the processing method processing bite of forming flat drill, it is high-efficient, but
When on deep hole drilling and boring machine using segmentation chit drill processing orthodrome, due to the equipment limitation of deep hole drilling and boring machine（Artificial control is deep
Degree）, several sections of circular arcs connect depth dimensions and diameter dimension at knife and are difficult to control, and exist after circular arc molding and connect knife print, influence product matter
Amount.
Utility model content
A kind of realization diameter of phi 200- is provided the purpose of the utility model is to overcome the deficiencies in the prior art
The processing of 2.5 meters of 300 depth of Φ or more blind hole inner hole bottom circular arc molding, it is blind instead of the molding numerically controlled lathe circular arc of former deep hole chit drill
Hole chit drill forming processing device, solving deep hole drilling and boring machine chit drill processing and forming, to connect depth dimensions and diameter dimension at knife not easily-controllable
The shortcomings that processed, improves the quality assurance power of product processing.
What the purpose of this utility model was realized in：
A kind of numerically controlled lathe circular arc blind hole chit drill forming processing device, including chit drill, the chit drill cutter hub of installation chit drill, installation
The knife bar of chit drill cutter hub being connected to by cutting tool arbor for CNC machine tool seat on numerically-controlled machine tool rest, it is characterised in that：The knife bar is
Eccentric knife bar.
Chit drill cutter hub is connected on eccentric knife bar by tailing screw flight.
The high offset of the knife rest of numerically-controlled machine tool and the center of chuck is identical as the eccentric eccentricity value of knife bar.
The utility model is up to following effect afterwards by adopting the above technical scheme：It realizes blind using realization numerically controlled lathe circular arc
The processing unit (plant) of hole chit drill processing and forming realizes that the molding of 2.5 meters of 300 depth of diameter of phi 200- Φ or more circular arc blind hole chit drill adds
Work can effectively control chit drill processing and forming and connect depth dimensions and diameter dimension at knife, and control precision accuracy is high, improves product
Processing quality.
Detailed description of the invention
Fig. 1 is that the processing unit (plant) assembling processing of the realization numerically controlled lathe circular arc blind hole chit drill processing and forming of the utility model is shown
One of be intended to.
Fig. 2 is the assembling processing of the processing unit (plant) of the realization numerically controlled lathe circular arc blind hole chit drill processing and forming of the utility model
The two of schematic diagram.
Specific embodiment
As shown in Figure 1, 2, the utility model includes knife bar 3, chit drill cutter hub 2, chit drill 1, and chit drill 1 is mounted on chit drill cutter hub 2
On, for chit drill cutter hub 2 using being threadedly coupled on knife bar 3, knife bar 3 is connected to numerically-controlled machine tool rest by cutting tool arbor for CNC machine tool seat
On.Knife bar 3 is designed as eccentric knife bar, since the center that deep hole drilling and boring machine awards oily device bracket and boring bar support and machine chuck is high by one
Cause property is good, but there are certain offsets for the center height of the knife rest of numerically-controlled machine tool and chuck.If directly processing will cause chit drill
It is inconsistent with the center of workpiece 5, cause inner hole deflection.The design of eccentric knife bar solves this processing problems, according to what is measured
The high offset 4 of the knife rest of numerically-controlled machine tool and the center of chuck, designs and produces eccentric knife bar, and when assembly adjusts center height, realizes
Numerically controlled lathe circular arc blind hole chit drill processing and forming.It is controlled when numerically-controlled machine tool chit drill processing and forming circular arc blind hole using numerical control program
The feeding depth of chit drill can effectively control chit drill processing and forming and connect depth dimensions and diameter dimension at knife, and control precision is quasi-
True property is high.The high offset 4 of the knife rest of numerically-controlled machine tool and the center of chuck is identical as the eccentric eccentricity value of knife bar.6 be to connect knife in figure
Point.
