Abstract
The utility model belongs to the field of machine tool fittings and relates to an automatic broaching device of an extending mill head. An extending mill head main shaft is mounted inside an extending mill head box body, a support sleeve is inserted inside an inner cavity of the extending mill head main shaft in the axial line direction, a broaching pole is inserted in an inner cavity of the support sleeve in the axial line direction, a standard blind rivet is fixed at the upper end of the broaching pole, a butterfly spring is sleeved on the broaching pole on the lower side of the inner cavity of the support sleeve, and a standard pull claw is fixed at the lower end of the broaching pole. The utility model realizes cutter replacement without detaching the mill head, and the broaching operation and the loosing operation of the automatic broaching device are synchronous to those of a main shaft of a machine tool; moreover, the automatic broaching device has the advantages of accurate operations, simple structure, convenient maintenance, safety and reliability.
Description
Technical field
The utility model relates to machine tool field, and 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
Extend the problem that the extension milling head need be dismantled and install to milling head replacing cutter in order to solve, extend the milling head internal structure by changing, be implemented in need not dismantle under the situation of extending milling head and just can change cutter, the utility model provides a kind of automatic tool-broaching device that extends milling head.
The technical scheme that its technical problem that solves the utility model adopts 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 utility model also can be realized 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 beneficial effects of the utility model are, 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.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 the utility model broaching tool state installation diagram.

Place, Fig. 3 the utility model location 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, be equipped with in the utility model extension milling head casing 14 and extend 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 utility model 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 utility model) 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.
