Description of drawings
The object of the invention, advantage and characteristics will illustrate through the non-limitative illustration of following preferred embodiment and explain.These embodiment only are the prominent examples of using technical scheme of the present invention, and all technical schemes of taking to be equal to replacement or equivalent transformation and forming all drop within the scope of requirement protection of the present invention.In the middle of these accompanying drawings,
Fig. 1 is the structure intention of this PCB drilling machine Z axle construction.
The implication of each Reference numeral is following among the figure:
1 Z axle base plate, 2 motor stators
3 electric movers, 4 upper flanges
5 steel wires, 6 lower flanges
7 main shaft trays, 8 main shafts
9 air admission holes, 10 air-float guide rails
11 supports
The specific embodiment
A kind of PCB drilling machine Z axle construction as shown in Figure 1 includes Z axle base plate 1, and its unusual part is: be fixed with motor stator 2 on the Z axle base plate 1 that the present invention adopts, on this motor stator 2 electric mover 3 be installed.Simultaneously, on electric mover 3, be connected with an end of steel wire transmission component, the other end of steel wire transmission component connects main shaft 8.And, be arranged with the air-float guide rail assembly outside the main shaft 8, main shaft 8 is accomplished in the air-float guide rail assembly moved up and down.Moreover the air-float guide rail 10 that the present invention adopts links to each other with Z axle base plate 1.
With regard to the present invention's one preferred implementation, the air-float guide rail assembly includes air-float guide rail 10, is arranged with main shaft 8 in the said air-float guide rail 10, and air-float guide rail 10 is outside equipped with support 11, and described support 11 is fixed on the Z axle base plate 1.Simultaneously, consider the need of work of air-float guide rail 10, on air-float guide rail 10, be distributed with air admission hole 9.Like this; In the course of the work; Main shaft 8 cylindricals are by air film encirclement uniformly, and main shaft 8 is positioned at the center of air-float guide rail 10 under the effect of air film, because main shaft 8 cylindricals have very high circularity and axiality; So when main shaft 8 moved up and down, air-float guide rail 10 can well guarantee the perpendicularity of its motion.
Further, consider that air-float guide rail 10 its air supporting thrusts must be able to overcome connector above the main shaft 8 because the active force that kinematic error produces.Thus, the steel wire transmission component that adopts to the present invention includes upper flange 4 and lower flange 6.Specifically, upper flange 4 links to each other with electric mover 3, and lower flange 6 links to each other with main shaft 8 through main shaft tray 7, between upper flange 4 and lower flange 6, is connected with steel wire 5, and this steel wire 5 axially has rigidity radially having elasticity.
Further come, upper flange 4, lower flange 6 adopt with steel wire 5 threes and are threaded again.Certainly, consider different manufacturing demands, its three is welded to connect or bonding connection.Moreover in order to adapt to different environments for use, its three can also one machine-shaping.Thus, can overcome the active force that kinematic error produces.Because steel wire 5 connects main shaft 8, makes main shaft 8 have the free degree in X, Y direction, make main shaft 8 motion vertical when guaranteeing air-float guide rail 10 effect main shafts 8.And the Z axle is to be rigidly connected, and guarantees the accuracy of 8 times drilling depths of main shaft.
Through above-mentioned character express and combine accompanying drawing to find out, adopt the present invention after, can effectively overcome the connector above the main shaft because the active force that kinematic error produces has the borehole accuracy height, Installation and Debugging are convenient.Specifically, high-accuracy air-float guide rail guarantees the borehole accuracy of boring; The Z axle omits two accurate line slideways, has reduced the difficulty of processing of part simultaneously through structural design, has reduced the processing and manufacturing cost of part; Be used through the ingenious of high-accuracy air-float guide rail and steel wire, greatly reduce the assembly precision requirement of Z axle, improved the efficiency of assembling of Z axle.And unitary construction of the present invention is simple, and the device fabrication cost is low.
