Description
Technical field
The utility model relates to fraise jig field, specifically relates to a kind of drilling attachment.
Background technology
Drill bit is to go out through hole or blind hole in order to drilling on solid material, and can be to the cutter of existing hole reaming.According to different structures, can be divided into the kinds such as fluted drill, chit drill, centre drill, depth drill and cylindrical drill.Although different bit edge mouth structures differ, the afterbody of drill bit is all groove shape structures, for coordinating with the clamping device of electric hammer or electric drill.
Bit grooves mostly is CNC milling machine milling at present.But in actual production, be limited to the factor of fixture, once can only process a drill bit, inefficiency.Meanwhile, only clamping drilling bit radially of existing fixture, drill bit is subject to the pressure of milling cutter can produce slight circular runout adding man-hour, therefore causes groove deep mixed, so cause drill bit in use circle skip large.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, and a kind of drilling attachment is provided.
A kind of drilling attachment, comprises grip slipper, the first Mobile base, the first screw rod, the second Mobile base and the second screw rod; On described grip slipper, be evenly arranged at intervals with at least 4 scroll chucks for clamping drilling bit, corresponding the first through hole connecting with scroll chuck centre bore that is provided with on grip slipper; On described grip slipper, be also provided with the second through hole and third through-hole; Described the first Mobile base and the second Mobile base lay respectively at the both sides of grip slipper, and the first Mobile base is used for propping up drill bit afterbody, and the second Mobile base is used for propping up drill bit head, and the first Mobile base and the second Mobile base match and provide axial chucking power to drill bit; One end of the first screw rod is fixedly connected with the first Mobile base, and the other end of the first screw rod passes the second through hole, is also provided with 2 nuts on the first screw rod, and 2 nuts lay respectively at the both sides of grip slipper; One end of the second screw rod is fixedly connected with the second Mobile base, and the other end of the second screw rod passes third through-hole, is also provided with 2 nuts on the second screw rod, and 2 nuts lay respectively at the both sides of grip slipper.
Preferably, described grip slipper, the first Mobile base, the first screw rod, the second Mobile base and the second screw rod are high-speed steel material.
Preferably, on described the second Mobile base, be also provided with the second through hole passing for the first screw rod.
Preferably, described third through-hole is positioned at the first Mobile base below.
The beneficial effects of the utility model are: saved tool setting operation, improved workman's operating efficiency, the drill bit of energy batch machining same size.

Wherein: 1, grip slipper, 2, scroll chuck, 3, the first Mobile base, 4, the second screw rod, 5, nut, 6, the second Mobile base, 7, the first screw rod, 8, the second through hole, 9, third through-hole, 10, the first through hole.
The specific embodiment
Embodiment 1: a kind of drilling attachment, its structure as Figure 1-4: comprise grip slipper 1, the first Mobile base 3, the first screw rod 7, the second Mobile base 6 and the second screw rod 4; On described grip slipper 1, be evenly arranged at intervals with at least 4 scroll chucks 2 for clamping drilling bit, corresponding the first through hole 10 connecting with scroll chuck 2 centre bores that is provided with on grip slipper 1; On described grip slipper 1, be also provided with the second through hole 8 and third through-hole 9; Described the first Mobile base 3 and the second Mobile base 6 lay respectively at the both sides of grip slipper 1, and the first Mobile base 3 is for propping up drill bit afterbody, and the second Mobile base 6 is for propping up drill bit head, and the first Mobile base 3 and the second Mobile base 6 match and provide axial chucking power to drill bit; One end of the first screw rod 7 is fixedly connected with the first Mobile base 3, and the other end of the first screw rod 7 passes the both sides that are also provided with 5,2 nuts 5 of 2 nuts on the second through hole 8, the first screw rods 7 and lay respectively at grip slipper 1; One end of the second screw rod 4 is fixedly connected with the second Mobile base 6, and the other end of the second screw rod 4 passes the both sides that are also provided with 5,2 nuts 5 of 2 nuts on third through-hole 9, the second screw rods 4 and lay respectively at grip slipper 1; Described grip slipper 1, the first Mobile base 3, the first screw rod 7, the second Mobile base 6 and the second screw rod 4 are high-speed steel material; On described the second Mobile base 6, be also provided with the second through hole 8 passing for the first screw rod 7; Described third through-hole 9 is positioned at the first Mobile base 3 belows.
Before use, first with vise, grip slipper 1 lower end is clamped.
When use, first the second Mobile base 6 is pulled down, then according to drill bit technological requirement, determined the distance of the first Mobile base 3 and grip slipper 1, then use nut 5 by fastening the first screw rod 7.Then drill bit is inserted in scroll chuck 2, drill bit afterbody props up the first Mobile base 3, fastening scroll chuck 2, and drill bit is clamped.Finally the second screw rod 4 is inserted to third through-hole 9, make the head of drill bit prop up the second Mobile base 6, and by fastening the nut 5 on the second screw rod 8.
Distance between scroll chuck 2 is identical, and the distance of adjacent drill bit is also identical.Add man-hour, inner side drill bit afterbody is defined as zero point, then the distance input between drill bit is entered to CNC milling machine, can process.After complete first drill bit of milling tool, according to distance moving to the second the drill bit zero point of input, carry out repetition milling, therefore omitted repeatedly tool setting and determine the operation at zero point, improved workman's working (machining) efficiency.
When milling, scroll chuck 2 provides radially chucking power for drill bit, the first Mobile base 3 and the second Mobile base 6 provide axial chucking power, having overcome traditional clamping device only can provide the drawback of axial chucking power, and while therefore having solved milling, drill bit is subject to milling cutter pressure at right angle to produce micro-circular runout and causes the deep mixed problem of groove.
By reference to the accompanying drawings the specific embodiment of the present invention is described although above-mentioned; but not limiting the scope of the invention; one of ordinary skill in the art should be understood that; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection scope of the present invention.
