Description
Technical field:
The utility model relates to a kind of machine tool component, the link gear of particularly a kind of cam robot tool changing of vertical, horizontal Machining centers and machining center main shaft pine cutter.
Background technology:
The machining center lathe is can be processed automatically by CNC control, automatic tool changer, and can finish multiple operation at a clamping, multiplex's kind (is milled, boring, bore, expand, the hinge tapping) a kind of Digit Control Machine Tool, the loose cutter cutter-exchange mechanism of existing machining center is that a multiple mounted cam that is supported on the lathe bed is arranged, multiple mounted cam and connecting rod and hexagonal axis match, connecting rod connects sliding axle with hexagonal axis, the other end of sliding axle connects manipulator, the cutter pine pull bar that matches and be positioned at main shaft with manipulator, the power set (mostly be oil cylinder and control device thereof) of external end head tipping on main spindle box of cutter pine pull bar are used to strain cutter and loosening cutter.On lathe bed, also be provided with a reducing motor that joins with electric control gear and be used to drive multiple mounted cam.Main spindle box moves to the tool changing position together with the cutter on main shaft and the main shaft during tool changing, drive oil cylinder by control device and make cutter pine pull bar loosening cutter, driving multiple mounted cam by reducing motor simultaneously rotates, drive manipulator behavior by connecting rod and hexagonal axis again, cutter is taken out in main shaft and rotate and change cutter, strain the cutter of being changed by cutter pine pull bar again, after tool changing finished, main spindle box shifted out the tool changing position together with the cutter in main shaft and the main shaft, cutter pine pull bar.The tool changing device of this structure is the tool changing action of being finished by two drive units, and action does not link, and in exchanging knives process, needs respectively repeatedly starter motor and repeated detection position, makes cutter long swap time thus, and motion process is unreliable.
Summary of the invention:
The purpose of this utility model provides link gear a kind of tool changing action interlock, short, the reliable cam robot tool changing of motion process swap time and the loose cutter of machining center main shaft, overcomes the deficiencies in the prior art.
Technical solution of the present utility model is: the link gear of a kind of cam robot tool changing and machining center main shaft pine cutter, it comprises the multiple mounted cam 5 that is supported on the lathe bed, multiple mounted cam 5 matches with connecting rod 3 and hexagonal axis 4, connecting rod 3 connects sliding axle 2 with hexagonal axis 4, the other end of sliding axle 2 connects manipulator 1, the cutter pine pull bar 10 that matches and be positioned at main shaft 7 with manipulator 1, it is characterized in that: the external end head of described cutter pine pull bar 10 matches with cam 11, the axle 14 of cam 11 connects decelerator 16, decelerator 16 is fixed on the main spindle box and connects motor 12, axle 14 terminations and the axle of cam 11 are provided with joint element 17 between 18, axle 18 be supported on the lathe bed and and multiple mounted cam 5 spools 19 between establish transmission device.
Described transmission device is the cog belt transmission.
The utility model compared with prior art because loose cutter, strain cutter and take off cutter, the exchange cutter action finish by a drive unit, so the tool changing of this device action links, shortened the swap time of cutter, motion process is reliable, need not repeatedly to start drive unit and repeated detection position.
Description of drawings:
Fig. 1 is the structural representation of the utility model specific embodiment;
Fig. 2 is an I place enlarged drawing shown in Figure 1.
The specific embodiment:
As shown in the figure: 7 is main shaft, is contained on the main spindle box.Main spindle box is driven and can be slided on lathe bed by drive unit.With bearing and bearing block axle 19 being supported on the lathe bed, is key connecting between multiple mounted cam 5 and the axle 19.Multiple mounted cam 5 matches with connecting rod 3 and hexagonal axis 4, and connecting rod 3 connects sliding axle 2 with hexagonal axis 4, and the other end of sliding axle 2 connects manipulator 1, the cutter pine pull bar 10 that matches with manipulator 1 and be positioned at main shaft 7.Above-mentioned is the prior art part, no longer describes in detail.The external end head of described cutter pine pull bar 10 is equipped with roller 15, and roller 15 matches with the cam 11 of plane formula, and cam 11 is fixedly mounted on the axle 14, can be key connecting with axle 14.Axle 14 joins with the output shaft of decelerator 16, can be structure as a whole with this output shaft.Decelerator 16 is bolted on the main spindle box, and the output shaft of the power shaft of decelerator 16 and motor 12 links.Motor 12 connects with decelerator 16 bolting.Axle 14 terminations and the axle of cam 11 are provided with joint element 17 between 18, and joint element 17 be traditional latch form, and promptly an axle 18 and axle 14 two ends plug when touching and can reach the diaxon coupled situation, and spools 14 also can separate with the mobile diaxon that make of main spindle box.With bearing and bearing block axle 18 is supported on the lathe bed.Establish transmission device between the axle 19 of axle 18 and multiple mounted cam 5.Described transmission device can be the profile of tooth belt, carries out transmission by cog belt 13, profile of tooth belt wheel 20, back shaft 9, also can adopt other type of belt drive.In this structure after 5 actions of loose cutter broaching tool and cam to get cutter tool changing action only be that a drive unit is a motor 12.
During tool changing, main spindle box moves to the tool changing position together with the cutter 8 on main shaft 7 and the main shaft 7, and this moment, axle 14 engaged with axle 18.By motor 12, decelerator 16 drives cam 11 and rotates, unclamp cutter 8 in the main shaft 7 by roller 15 and loose pull bar 10 again, simultaneously by axle 14, joint element 17, axle 18, profile of tooth belt wheel 20, cog belt 13 driving shafts 19, multiple mounted cam 5 rotates, drive manipulator 1 action by connecting rod 3 and hexagonal axis 4 again, cutter is taken out in main shaft 7 and rotate and change cutter, again by the cutter that cooperate tension changed of cutter pine pull bar 10 with cam 11, after tool changing finishes, main spindle box is together with the cutter of being changed in main shaft 7 and the main shaft 78, cutter pine pull bar 10, decelerator 16, cam 11, axle 14 shifts out the tool changing position together and carries out next step processing action, and this moment, axle 14 separated with axle 18.
