Abstract
The utility model provides a take drill bushing of chip breaking function, relates to the machining field. Include boss, the locating surface supporting with drill jig, the locating surface inner zone has the guiding hole that is used for installing the drill bit, realizes to iron fillings that the chip breaking tooth of chip breaking sets up in the bottom of locating surface, is equipped with on the boss to make the groove that compresses tightly that the drill bushing fixed a position on drill jig, the chip breaking tooth is four, and the equipartition is in the bottom of locating surface, and every chip breaking tooth comprises vertical face, plane, inclined plane, and the inclined plane becomes 60 degrees angles with vertical face. The utility model discloses a when drill bit processing part was rotatory, iron fillings were rotatory along with the drill bit, and when iron fillings touched drill bushing chip breaking tooth, the chip breaking tooth blockked the production counter -force to iron fillings to make iron fillings drawing breakage, disconnection. Simple structure, easy and simple to handle, the rigidity is good, and low in manufacturing cost for the drill bushing provides the chip breaking function, has improved the life of part surface quality and drill bit greatly.
Description
Technical field
The utility model relates to Machining Technology field, specifically a kind of drill bushing of the band chip breaking function used in boring procedure.
Background technology
In mechanical processing process, often use the frock processing parts of band bushing plate, all with drill bushing on bushing plate, for being led by drill bit, in case part bores partially by drill bit.In process, drill bit is wound around by drilling cuttings, and rotates in the lump with drill bit, often causes the treatment of surfaces of components to be occurred by situations such as iron filings scuffing, the easy scaling loss of drill bit, and the port of export of traditional drill bushing is generally planar structure or for cross-shaped groove structure, do not possess chip breaking function.
Summary of the invention
For overcoming the deficiencies in the prior art, goal of the invention of the present utility model is to provide a kind of drill bushing with chip breaking function, makes the chip breaking tooth of the drill bushing port of export realize chip breaking function to iron filings.
For achieving the above object, the utility model comprises the boss supporting with drill jig, locating surface, with the pilot hole for installing drill bit in locating surface, the chip breaking tooth realizing chip breaking to iron filings is arranged on the bottom of locating surface, and boss is provided with the pressing groove that drill bushing is located on drill jig.
Described chip breaking tooth is four, is distributed on the bottom of locating surface, and each chip breaking tooth is made up of vertical plane, plane, inclined-plane, and inclined-plane becomes 60 degree of angles with vertical plane.
Compared with prior art, when drill bit processing parts rotates, iron filings are with bit, and when iron filings touch drill bushing chip breaking tooth, chip breaking tooth stops generation counter-force to iron filings, thus makes iron filings drawing crack, disconnection for the utility model.Structure is simple, and easy and simple to handle, good rigidly, low cost of manufacture, for drill bushing provides chip breaking function, substantially increases the service life of surface quality of workpieces and drill bit.

Fig. 1 is stereochemical structure simplified schematic diagram of the present utility model.
Fig. 2 is the profile of Fig. 1.
Fig. 3 is the top view of Fig. 2.
Fig. 4 is the expansion schematic diagram of the chip breaking tooth of Fig. 1.
Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3, Figure 4, the utility model comprises boss 1, locating surface 2, pilot hole 3, chip breaking tooth 4 and pressing groove 5, and with pilot hole 3 in locating surface 2, chip breaking tooth 4 is arranged on the bottom of locating surface 2, and boss 1 is provided with pressing groove 5.Boss 1 and locating surface 5 are arranged on drill jig, and by adopting screw to push down pressing groove 5, drill bushing is located on fixture, and pilot hole 3 makes drill bit lead in drill bushing, and chip breaking tooth 4 pairs of iron filings of the drill bushing port of export realize chip breaking function.
Described chip breaking tooth 4 is four, is distributed on the bottom of locating surface 2, and each chip breaking tooth 4 is made up of vertical plane 6, plane 7, inclined-plane 8, the 60 degree of angles in inclined-plane 8 and vertical plane 6 one-tenth.
During use, identical with traditional drill bushing using method, when drill bit processing parts rotates, iron filings are with bit, and when iron filings touch the chip breaking tooth 4 of drill bushing, chip breaking tooth 4 pairs of iron filings stop generation counter-force, thus make iron filings drawing crack, disconnection, realize chip breaking function.
