Abstract
The invention relates to an automatic broaching device of an extended cutter head, belonging to the field of machine tool fittings. An extended cutter head box is internally provided with the main shaft of an extended cutter head; the inner cavity of the main shaft of the extended cutter head is inserted with a support sleeve along the axial direction; the inner cavity of extended cutter head is inserted with a broaching rod along the axial direction; a standard pull nail is fixed at the upper end of the broaching rod; the broaching rod at the lower side of the inner cavity of the support sleeve is sleeved with a disc-shaped spring; and a standard pull claw is fixed at the lower end of the broaching rod. The automatic broaching device can replace a cutter under the condition that the extended cutter head does not need to be disassembled, and the motion of a broach and a released cutter is synchronous with the main shaft of the machine tool, so that the automatic broaching device has exact motion, simple structure, convenient maintenance, security and reliability.
Description
Technical field
The present invention relates to machine tool field, especially large-sized gantry machine extends the automatic tool-broaching device of milling head.
Background technology
As everyone knows, large-sized gantry machine need use the extension milling head when some peculiar part of processing, at present, the extension milling head that is equipped with except minority advanced person's large-sized gantry machine has the automatic tool-broaching function, all the other most of milling heads that extend all are to use a long broaching tool bar manually to strain cutter, all to unload from lathe extending milling head earlier when changing cutter at every turn, to extend milling head after the operator manually more finishes changing cutter again is installed on the lathe, the time-consuming effort again of this structure, reduce production efficiency widely, increased production cost.
Summary of the invention
To extend the problem that the extension milling head need be dismantled and install to milling head replacing cutter in order solving, to extend the milling head internal structure, be implemented in to dismantle under the situation of extending milling head and just can change cutter, the invention provides a kind of automatic tool-broaching device that extends milling head by changing.
The technical solution adopted for the present invention to solve the technical problems is: a kind of automatic tool-broaching device that extends milling head, extend to be equipped with in the milling head casing and extend the milling head main shaft, extend milling head main shaft inner chamber and be fitted with support set along axis direction, the support set inner chamber is fitted with the broaching tool bar along axis direction, broaching tool bar upper end is fixed with the standard blind rivet, be set with disk spring on the broaching tool bar of support set inner chamber downside, broaching tool bar lower end is fixed with the standard pulling claw.
The present invention also can realize by following measure: the support set lower end is connected with the pulling claw cover, and pulling claw is positioned at pulling claw cover inner chamber.
The invention has the beneficial effects as follows, the action of the broaching tool of this automatic tool-broaching device is that the broaching tool by machine tool chief axis moves and realizes, the loose cutter action of this automatic tool-broaching device then is the loose cutter action by machine tool chief axis, adds the disk spring action realization together in this device.The ingenious combination of this automatic tool-broaching device and machine tool chief axis automatic tool-broaching device, the common hydraulic cylinder mechanism of using machine tool chief axis in the time of action, thus make this automatic tool-broaching device save the control components and parts of realization necessary hydraulic cylinder mechanism of action and the action of control hydraulic cylinder.Simultaneously, realized under the situation that need not dismantle the extension milling head, just changing cutter, and the action of broaching tool and loose cutter and machine tool chief axis is synchronous.This automatic tool-broaching device action is accurate, simple in structure, easy to maintenance, safe and reliable.

Place, Fig. 3 location of the present invention partial enlarged drawing
1. standard blind rivets, 2. dust ring, 3. sliding bearing among the figure, 4. the location is covered, 5. broaching tool bar, 6. support set, 7. adjusting pad, 8. disk spring, 9. sleeve, 10. pulling claw cover, 11. standard pulling claws, 12. cutters, 13. extend the milling head main shaft, 14. extend milling head casing, 15. machine tool chief axis automatic tool-broaching devices, 16. connected body, 17. glands.
The specific embodiment
Fig. 1, Fig. 2, shown in Figure 3, the present invention extends to be equipped with in the milling head casing 14 and extends milling head main shaft 13, extend milling head main shaft 13 inner chambers and be fitted with support set 6 along axis direction, support set 6 inner chambers are fitted with broaching tool bar 5 along axis direction, broaching tool bar 5 upper ends are fixed with standard blind rivet 1, be set with sliding bearing 3 on the broaching tool bar 5 of standard blind rivet 1 bottom, sliding bearing 3 is fastened on connected body 16 upper ends, connected body 16 is fixed on by involute spline pair and long spiro nail and extends on the milling head main shaft 13 (transmitting the moment of torsion of machine tool chief axis by the keyway on the connected body 16), sliding bearing 3 tops are fixed with dust ring 2, extension milling head main shaft 13 inner chambers upper end is established gland 17 is installed, support set 6 is glanded 17 and is fixed on extension milling head main shaft 13 upper ends, the location is covered 4 and is fixed together through bolt and support set 6, be set with disk spring 8 on the broaching tool bar 5 of support set 6 inner chamber downsides, be set with adjusting pad 7 on the broaching tool bar 5 of disk spring 8 upper ends, be set with sleeve 9 on the broaching tool bar 5 of disk spring 8 lower ends, disk spring 8 is compressed between sleeve 9 and the adjusting pad 7, support set 6 lower ends are fixed with pulling claw cover 10, and pulling claw overlaps 10 inner chambers and is provided with the standard pulling claw 11 that is fixed together with broaching tool bar 5 lower ends.Standard blind rivet 1 was grabbed and is stuck on the machine tool chief axis automatic tool-broaching device 15 when the present invention used, and 11 of standard pulling claws are in order to grasp cutter 12.
In Fig. 1, after the broaching tool action takes place in machine tool chief axis automatic tool-broaching device 15, tension standard blind rivet 1 moves upward, driving standard pulling claw 11 by broaching tool bar 5 again moves upward, move (stroke of machine tool chief axis automatic tool-broaching device is greater than stroke of the present invention) after certain stroke, standard pulling claw 11 is retracted among the pulling claw cover 10 fully, and cutter 12 is tightened up.Meanwhile, disk spring 8 is compacted.
In Fig. 2, after loose cutter action takes place in machine tool chief axis automatic tool-broaching device 15, disk spring 8 compacted in moving process to flicks rapidly, standard pulling claw 11, broaching tool bar 5, standard blind rivet 1 are moved downward, move after certain stroke, standard pulling claw 11 opens after exposing pulling claw cover 10, and standard pulling claw 11 continues to move downward, the inner face of standard pulling claw 11 pushes up the blind rivet upper surface of cutter 12, and cutter 12 is released under the effect of impulsive force.After cutter 12 unclamped, the shaft shoulder of broaching tool bar 5 bumped against the location and covers 4 backs (as shown in Figure 3), and standard pulling claw 11 stops to move downward.After changing cutter 12, repeat the action among Fig. 1 again, cutter 12 is tightened up once more.
