Description

Rhinestone head water jacket
Technical field
The utility model relates to a kind of electric drill technical field for glass punching, particularly connects the water jacket of rhinestone head and electric drill.
Background technology
Existing rhinestone head water jacket oil sealing seals central shaft, this oil sealing directly and overcoat rub, service life is short, easily leaks, and needs often to change oil sealing, causes cost high like this, affects operating efficiency; Its drill point part of installing drill bit can be dismantled, and this position easily leaks, and causes drill point to get rusty, and reduces service life.
Utility model content
Not enough for overcoming above-mentioned prior art, the utility model discloses a kind of rhinestone head water jacket, good sealing effect, long service life, avoid operating personnel frequently to change seal.
The technical scheme that the utility model adopts is a kind of rhinestone head water jacket, comprise overcoat, central shaft, central shaft is by drill bit shaft, axis and electric drill folder axle are formed, wherein axis, drill bit shaft is hollow shaft, the centre of axis arranges location star and inlet opening, location star and inlet opening lay respectively at axis both sides and Central Symmetry, locating ring is enclosed within axis, locating ring is beaten centrosymmetric holes, wherein locating ring is positioned on the star of location by a hole set screw, align with inlet opening in another hole, axis and electric drill press from both sides one end that axle is connected establishes draw-in groove, draw-in groove is equal with its length to the length of the axis other end, axis overlaps the mechanical water seal of two covers, the mechanical water seal of two covers lays respectively at locating ring both sides, machinery water seal outer end bearing extrudes, bearing connects central shaft and overcoat, the centre position of overcoat punches, outside, hole connects water inlet tap.
Described overcoat divides two ends, middle three parts, and mid portion internal diameter is little, and two end portions internal diameter is large, and two end portions is the same, and water seal determined by machinery, bearing connects overcoat and is positioned at overcoat two end portions
The beneficial effects of the utility model are that sealing is tight, water-tight, avoid frequently changing seal, long service life.Good sealing effect, easy to operate, with low cost, be adapted at the electric drill for the punching of glass specialty is applied.
Accompanying drawing explanation
Fig. 1 is the utility model cross-sectional view, and Fig. 2 is the utility model central shaft and locating ring structure schematic diagram.
Detailed description of the invention
As shown in Figure 1, a kind of rhinestone head water jacket, comprise overcoat 1, central shaft 11, central shaft 11 is by drill bit shaft 9, axis 5 and electric drill folder axle 4 are formed, wherein axis 5, drill bit shaft 9 is hollow shafts, short than axis 5 of electric drill folder axle 4 diameter, short than drill bit shaft 9 of axis 5 diameter, hollow 10 of drill bit shaft 9 center is conical structure, the drill bit shaft 9 of central shaft 11, axis 5, electric drill folder axle 4 be disposable lathe car out, axis 5, the disposable car of hollow lathe of drill bit shaft 9 goes out, the centre of axis 5 arranges location star 13 and inlet opening, location star 13 and inlet opening lay respectively at axis 5 both sides and Central Symmetry, locating ring 12 is enclosed within axis 5, locating ring 12 is beaten centrosymmetric two circular holes 14, wherein locating ring 12 is positioned on the star 13 of location by a circular hole 14 set screw, another circular hole 14 aligns with inlet opening, axis 5 and electric drill press from both sides one end that axle 4 is connected establishes draw-in groove 15, draw-in groove 15 is equal with overcoat 1 length to the length of axis 5 other end, axis 5 overlaps the mechanical water seal of two covers, the mechanical water seal of two covers lays respectively at locating ring 12 both sides, machinery water seal moves water seal 8 by machinery, machinery is determined water seal 6 and is formed, the dynamic water seal 8 of machinery is arranged on axis 5, machinery is determined water seal 6 outer end bearing 2 and is extruded, two bearings 2 is enclosed within axis 5 two ends respectively, central shaft 11 penetrates overcoat 1, overcoat 1 point of two ends, middle three parts, mid portion internal diameter is little, two end portions internal diameter is large, two end portions is the same, water seal 6 determined by machinery, bearing 2 connects overcoat and is positioned at overcoat two end portions, draw-in groove 15 is installed jump ring 3, prevent bearing 2 from coming off, the centre position of overcoat 1 punches, outside, hole connects water inlet tap 7.
When the utility model uses, water inlet tap 7 connecting water pipe, drill bit shaft 9 installs taper-shank drill, electric drill folder axle 4 clamped by electric drill, electric drill band central shaft 11 rotates, and central shaft 11 drives taper-shank drill to rotate, and overcoat 1 does not rotate, taper-shank drill is glass punching, meanwhile, water enters overcoat 1 by water inlet tap 7, and water enters axis 5 by the inlet opening on central shaft 11, drill bit shaft 9 is inner, then enter taper-shank drill inside, flow out at taper-shank drill and glass contact place.
