Description
Technical field
The present invention relates to field of machining, more particularly, it relates to tool-broaching mechanism.
Background technology
The cutter of five axle cutter and tool grinding machine processing to realize batch production, needs to use automatic charging equipment, matches
Special broach mechanism have to use, so when finger feed comes, by unclamping of Special broach mechanism controls handle of a knife
And clamping, it is achieved automatically reload.
Existing tool-broaching mechanism is divided into two kinds, and one is non-rotatable Standard Cylinder, and the rotation that another kind is expensive connects
Head.At present, tool-broaching mechanism mostly is the non-rotatable cylinder of standard and expensive swivel joint.After Standard Cylinder is ventilation source, logical
Move before and after crossing piston, it is achieved axially extended and retraction, but piston mandrel can not be realized and rotate in cylinder interior, in not having
Heart blowing function.
Above-mentioned existing apparatus has a problem in that:
1, piston mandrel cannot be realized rotate in cylinder interior, there is no center blowing function.
2, expensive, it is used for controlling handle of a knife clamping and unclamping bar, cost performance is the highest.
Summary of the invention
The present invention had both solved the Rotation of cylinder, reduced again the price of costliness.And assemble and adjustment side
Just, it is simple to keep in repair and change, good airproof performance, contamination resistance is strong；And the present invention is very easy to use, can be controlled by system
Pine folder action and center blowing function.Additionally, the present invention is equipped with different adnexa, the clamping of multiple handle of a knife can be realized.
In order to achieve the above object, the present invention provides the Special broach mechanism of a kind of rotary type, including by cylinder body and cylinder
Cover buckle connect form, inside arranges the cylinder-piston assembly of piston plate, described piston plate arranges rotary mandrel, institute by centre bore
State mandrel and pass through described cylinder body and the cylinder cap of both end sides with air-tight manner；Described piston plate both sides end face is respectively arranged with needle roller axle
Hold；The described needle bearing of side abuts on the step surface of one section of reducer on described mandrel；The described needle roller of opposite side
Bearing is locked by a locking nut being rotatably connected in described mandrel thread section.Additionally, the body body wall of described cylinder body and cylinder cap
In be provided with three induction pathway；It is the path entering described piston plate both sides cavity respectively, and enters described mandrel center
The path that axle axis hole is given vent to anger to the shank end port arranged；The air inlet of described three induction pathway lay respectively at described cylinder body or
The outside of cylinder cap arranges gas source interface.
Additionally, the outside that described cylinder cap is positioned at cylinder-piston assembly cylinder body arranges one section of sleeve sections being socketed described mandrel；
Spun outside described sleeve sections a rotating disk；Described rotating disk is provided with three described gas source interfaces.And then, described air inlet
In path, the docking location of three described gas source interfaces the most corresponding is respectively positioned on described sleeve sections.
Additionally, the rotary mandrel that the present invention relates to, referring to opposing pistons dish, mandrel can rotate, and the two holding is close
Envelope relation.And independent piston plate only does axial action, and do not rotate.
The present invention can be together with automatic charging device, it is achieved the function of automatic charging, improves working (machining) efficiency, reduces artificial
Put into, reduce buying and the maintenance finished product of equipment, increase economic efficiency.
Accompanying drawing explanation
Fig. 1 be tool-broaching mechanism of the present invention be embodied as main structure schematic diagram；
In figure: 1. mandrel；2. cylinder body；3. locking nut；4. piston plate；5. cylinder cap；6. needle bearing；7. rotating disk.
Detailed description of the invention
Shown in Fig. 1 is the example that is embodied as of the present invention, and the cylinder body 2 of tool-broaching mechanism and cylinder cap 5 form a closing
Cavity, as the running space of piston plate 4, rotating disk provides the input interface of source of the gas for whole broaching tool structure.Whole axle system by
Mandrel 1, locking nut 3, piston plate 4 and needle bearing 6 three-major-items assembly, be respectively arranged with one group of needle bearing 6 at piston plate 4 two ends,
It is used for supporting piston plate 4, and locks with locking nut 3, make piston plate 4 to rotate, sealing member is installed at each rotation, it is ensured that
The source of the gas stability of broaching tool structure, it is ensured that pulling force.
Running is: source of the gas is controlled by system, is optionally passed through. three corresponding interfaces of rotating disk 7, control axle
System stretch out, retracts and center air blowing three actions.The source of the gas internal holes by cylinder cap 5, enters on the right side of piston plate 4 and cylinder cap 5
Between cavity, give and piston plate 4 thrust forward, (import of A labelling and path) is stretched out by axle system.Source of the gas passes through cylinder cap 5 He
The internal holes of cylinder body 2, enters the cavity (import of C flag and path) on the left of piston plate 4 and between cylinder body 2, gives and piston plate 4
Thrust backward, axle system retracts.The source of the gas internal holes by cylinder cap 5, enters the inside (import of B labelling and path) of mandrel 1,
And by mandrel 1 leading portion spray, centered by blow, blow away processing remain on handle of a knife iron filings.
When handle of a knife changed by needs, use spanner rotary core shaft counterclockwise 1 rear end, support piston plate by needle bearing 6
4, it is ensured that piston plate 4 does not rotates, make mandrel 1 rotate under the support of needle bearing 6, the threaded connection place of mandrel 1 and handle of a knife by
Gradually disengage, pull down handle of a knife.When handle of a knife is installed, use spanner to turn clockwise mandrel 1 rear end, make the screw thread of mandrel 1 and handle of a knife even
The place of connecing gradually tightens, and completes the installation of handle of a knife.
Additionally, contact support by rotation Glais ring between piston plate 4 with cylinder casing wall, the frictional force of Glais ring is more than rolling
The frictional force of needle bearing 6, during so that it is guaranteed that mandrel rotates, piston plate 4 will not pivoting.And the two centre bore connected needs
Ensure air-tightness.
The above, the only present invention preferably detailed description of the invention, but protection scope of the present invention is not limited thereto,
Any those familiar with the art in the technical scope of present disclosure, according to technical scheme and
Inventive concept equivalent or change in addition, all should contain within protection scope of the present invention.
