It is provided with press box on the revolving door 2, transparent glass 12 is installed in the press box.
The main view of machine tooling center double change-table rotary door structure of the present invention as shown in Figure 2, the outer shield
Cover 1 and revolving door combine place, are respectively arranged with strong magnets 9, according to principle of opposite sex attraction, guarantee revolving door 2 in work work
After being restored to initial position in journey, revolving door 2 is constant with respect to the relative position of lathe and pallet changer 10.
The cross-sectional view in the direction main view A-A of the present invention as shown in Figure 3, primarily to comprehensively showing exchange work
Make the structure connection relationship between platform 10 and rotational structure in vertical structure.
In order to make rolling bearing units being more clear of modular construction, the present invention provides B in Fig. 3 of the present invention as shown in Figure 4
Locate the partial enlarged view of structure, the rolling bearing units component there are multiple rolling bearing units to form along axially stacking, the multiple to usher to seat
It is connected between bearing for axle sleeve, will not influence rotation；Fixed rotary shaft 13 passes through the circular hole among rolling bearing units 4, passes through bolt
It is connect with live spindle 5；Top rotary table 6 is attached by bolt with crossbeam 3, rolling bearing units 4 is encased, so that rolling bearing units 4 can
To be rotated in top rotary table 6；Transparent glass 12 is fixed on revolving door 2 by press box；Revolving door 2 is bolted on rotation
On main shaft 5, lathe provides power to live spindle 5, so that revolving door 2 rotates.
Lower rotary table of the present invention 7 as shown in Figure 5, spacer pin 8,10 3 kinds of workpiece of pallet changer three-dimensional combination figure, body
The relative positional relationship between spacer pin 8 and pallet changer 10 is showed, primarily to embodying spacer pin 8 in lower rotary table 7
The positional relationship of lower end.
The plan structure of the lower rotary table of machine tooling center double change-table rotary door structure of the present invention as shown in FIG. 6
Figure, the lower end of the lower rotary table 7 are provided with waist-shaped hole 71, fast mouth 72 are provided in the middle part of 7 lower end of lower rotary table, with the friendship
The protrusion being arranged in the middle part of structure turntable 11 of changing planes is in mating connection.
The cross-sectional view in the direction B-B in lower rotary table top view of the present invention as shown in Figure 7, the depth at 71 both ends of waist-shaped hole
Difference, the spacer pin 8 reach the other end of waist-shaped hole 71, the waist-shaped hole 71 after being rotated by 90 ° from one end of waist-shaped hole 71
The other end be provided with the deep hole greater than 40mm.
The working principle of machining center pallet changer 10 of the invention are as follows: when initial position, exchange mechanism turntable 11
Parallel with pallet changer 10, and then the driving motor of exchange mechanism turntable 11 drives the intermediate hook being arranged to be rotated by 90 °,
After exchange mechanism turntable 11 is lifted 40mm upwards by exchange oil cylinder, intermediate hook is linked into No. 1 pallet changer and 2 respectively
Number pallet changer, the intermediate hook strip of exchange mechanism turntable 11 is two 180 ° of worktable rotary dynamic, at this point, realizing No. 1 friendship
Change jobs the location swap of platform and No. 2 pallet changers.At this point, exchanging oil cylinder whereabouts 40mm, set among exchange mechanism turntable
The hook set will be separated from pallet changer, and the driving motor of exchange mechanism turntable 11 drives intermediate hook rotation
90 ° return to initial position.
A kind of work step of machine tooling center double change-table rotary door structure of the invention are as follows:
Start to work in machining center when, exchange mechanism turntable 11 is in initial position, and exchange mechanism rotates
Platform 11 is in relatively parallel state with revolving door 2；The working principle of machining center workbench 10 needs exchange mechanism turntable
It is first rotated by 90 °, therefore spacer pin 8 needs the first sky in the waist hole hole of lower rotary table 7 to be rotated by 90 °, and then, exchange oil cylinder lifts friendship
Structure turntable 11 of changing planes rises 40mm.
Because spacer pin 8 is fixed on exchange mechanism turntable 11, spacer pin 8 and exchange mechanism turntable
Convex portion on 11 rises 40mm together, until in the fast mouth that the convex portion on exchange mechanism turntable heads into lower rotary table 7,
So the waist-shaped hole being arranged on lower rotary table 7 will guarantee that the depth of its other end is greater than 40mm, spacer pin 8 just can guarantee
Lower rotary table 7 will not be bumped against, to guarantee the safety in uphill process.
It rotates 180 ° together after exchange mechanism turntable 11 tangles two pallet changer 10, exchanges oil cylinder to revolving door
2 provide power, and revolving door 2 can also rotate 180 °, to achieve the purpose that pallet changer, and realize processing district and feeding area
Separation.
Later, exchange mechanism turntable 11, which declines 40mm and is rotated by 90 °, returns to initial position, in the process, spacer pin 8
After exchange mechanism turntable 11 can be followed to decline 40mm together, spacer pin 8 is again in the waist-shaped hole of exchange mechanism turntable 11
It dallies again and returns to initial position after 90 °.
