Abstract
The utility model relates to a drilling tool, in particular to an improved drilling device for a bench drill. The improved drilling device comprises a sleeve sleeved on a drill bit seat, two grooves are arranged on the sleeve, the sleeve is fixed on the drill bit seat through a bolt and a nut, an inclined hole is drilled on the outer ring of the lower end of the sleeve, a chamfer cutter is installed in the inclined hole, and the tail end of the chamfer cutter is arranged in a drill bit chip exhaust groove. The improved drilling device can drill a work piece, and the purposes of locating hole depth and removing hole opening burrs can be simultaneously achieved when the work piece is clamped in one time. The improved drilling device can effectively eliminate hole depth disqualification caused by operation error, greatly improves work efficiency and is simple in structure and low in manufacture cost.
Description
Technical field
The utility model relates to boring bar tool, is specially bench drill boring modifying device.
Background technology
When using bench drill boring, drilling depth is a major parameter, present stage, determine that drilling depth roughly has two kinds of methods: the one, determine according to the bench drill scale, another kind method is directly to use depth gauge rule to measure, the former the absent minded or operate miss of operator may occur, causes hole depth not reach requirement; The latter wastes process time.After boring finishes, orifice chamfer (deburring) step that is absolutely necessary, and orifice chamfer mostly all needs again to change the drill bit larger than existing aperture and processes, the perhaps unified process equipment of an other special chamfering.If carry out chamfering according to above step, also need spended time to remove the reconditioning chmfer bit, more bit change perhaps makes workpiece have more together the separately operation of chamfering, has increased the time of Workpiece circulation and the waste of manpower; But also chamfering angle size, the depth, angle disunity may appear, affected the attractive in appearance of workpiece.
Although prior art can be processed as requested, efficient is on the low side, defective work occurs easily, and during especially for batch production, the time spent is long when measuring hole depth or orifice chamfer.
Summary of the invention
The utility model is for the problems referred to above, a kind of bench drill boring modifying device is provided, adopts this device in the situation of workpiece clamped one time, can when guaranteeing drilling depth, also machine by orifice chamfer, greatly improve operating efficiency, reduced the occurrence rate of defective work.
According to the technical solution of the utility model: bench drill boring modifying device comprises the sleeve that is set on the drill headstock, have two grooves on the described sleeve, be fixed on the drill headstock by bolt and nut, be drilled with inclined hole on the cylindrical of described sleeve lower end, in the described inclined hole chamfering tool is housed, described chamfering tool tail end places in the flute of drill.
Described chamfering tool is locked by holding screw.
Described inclined hole becomes 30 ° of angles with the sleeve baseplane.
Described inclined hole and sleeve baseplane angle at 45 °.
Described inclined hole becomes 60 ° of angles with the sleeve baseplane.
Described drill bit is installed on the drill headstock.
Technique effect of the present utility model is: use the utility model that workpiece is carried out Drilling operation, workpiece only needs clamped one time, can reach the purpose of locating simultaneously hole depth and removing the aperture burr; It is defective to adopt this covering device can effectively eliminate the hole depth that the human operational error causes; Adopt this covering device greatly to increase work efficiency; This covering device is simple in structure, and manufacturing cost is lower.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described.
Among Fig. 1, comprise sleeve 1, bolt 2, nut 3, holding screw 4, chamfering tool 5, drill headstock 6, drill bit 7, inclined hole 8 etc.
As shown in Figure 1, the utility model is that a kind of bench drill boring modifying device comprises the sleeve 1 that is set on the drill headstock 6, have two grooves on the described sleeve 1, be fixed on the drill headstock 6 by bolt 2 and nut 3, the height of sleeve 1 height can up-down adjustment, be drilled with inclined hole 8 on the described sleeve 1 lower end cylindrical, in the described inclined hole 8 chamfering tool 5 be housed, described chamfering tool 5 tail ends place in drill bit 7 chip areas.
Described chamfering tool 5 is by holding screw 4 lockings, and chamfering tool 5 is fixing.
Described inclined hole 8 becomes 30 ° of angles with sleeve 1 baseplane.
Described inclined hole 8 and angle at 45 °, sleeve 1 baseplane.
Described inclined hole 8 becomes 60 ° of angles with sleeve 1 baseplane.
Described drill bit 7 is installed on the drill headstock 6.
The course of work of the present utility model is as follows: when workpiece is carried out Drilling operation, to up and down by bolt 2 and nut 3, adjustable sleeve 1 is fixed on the drill headstock 6, be drilled with respectively on the lower end cylindrical of sleeve 1 and become 30 °, 45 °, 60 ° inclined holes 8 with its baseplane, can chamfering tool 5 be installed in 8 li of required inclined holes according to drawing requirement, then regulating sleeve 1 up and down the height and drill bit 7 extension elongations, determine drilling depth, next, regulate chamfering tool 5 extension elongations, its tail end is in drill bit 7 chip areas, locking holding screw 4, chamfering tool 5 is fixing.During work, chamfering tool 5 and drill bit 7 turn round and feed motion synchronously, drill bit 7 drillings are behind set depth, sleeve 1 baseplane contacts with workpiece planarization, this moment, drilling depth put in place, and chamfering tool 5 is also complete with chamfer machining, like this by clamped one time, just can reach the double effects that burr is removed in hole depth location and aperture.
But the utility model requires chamfering tool 5 to be installed on the sleeve 1 of up-down adjustment according to different angles, do synchronous revolving and feed motion with drill bit 7, reach accurate assurance drilling depth and remove simultaneously the effect of aperture burr, this apparatus structure is simple, is skillfully constructed.
The utility model carries out Drilling operation to workpiece, and workpiece only needs clamped one time, can reach the purpose of locating simultaneously hole depth and removing the aperture burr; It is defective to adopt this covering device can effectively eliminate the hole depth that the human operational error causes; Adopt this covering device greatly to increase work efficiency; This covering device is simple in structure, and manufacturing cost is lower.
