Consult shown in Fig. 2 to Fig. 7, a kind of long-stroke linear module that first embodiment of the invention provides, it formed primarily of slide unit 53 and a cover plate 80 in belt pulley 72, belt 73, after belt pulley 71, before slide unit 52, fixing rod 60, after slide unit 51, before pedestal 20, linear slide rail 30, ball screw 40.
Pedestal 20, has a length and is positioned at the long fixed block 21 to the nearly middle of X to X and.
Linear slide rail 30, comprise along long two slide rails 31 being fixedly arranged on pedestal 20 to X and in parellel of pedestal 20, be slidedly arranged on front-slider 32, rear slider 33 on each slide rail 31 and between forward and backward slide block 32,33 two in slide block 34.Because linear slide rail 30 is known members, and group establishes mode and manner of execution all with known identical, the design focal point of non-invention, therefore no longer describes in detail for the detailed construction of this component and manner of execution.
Ball screw 40, comprises one and is located at pedestal 20 pivotly and screw rod 41 and between two slide rails 31 is driven by screw rod 41 and is reciprocally located at the nut 42 on screw rod 41 movably along pedestal 20 is long to X.Because ball screw 40 is known members, and group establishes mode and manner of execution all with known identical, the design focal point of non-invention, therefore the detailed construction of this component and manner of execution are no longer described in detail, unlike, the present invention is into about being the long half to X length of pedestal 20 by the Design of length of screw rod 41.
Front slide unit 51, has pivot groove 513 before forward wing that front a group of establishing for nut 42 spiral shell establish portion 511, two to establish for front-slider 32 groups 512 and.
Rear slide unit 52, has the two rear alar part supplying rear slider 33 groups to establish 521 and rear pivot grooves 522.
Fixing rod 60, has a first end 61 and being arranged in front slide unit 51 and is in reverse to first end 61 and is arranged in the second end 62 of rear slide unit 52, makes forward and backward slide unit 51,52 produce equally spaced displacement.
Front belt pulley 71, is hubbed at front slide unit 51, and has front pivot 711 and a front wheele part 712 run through by front pivot 711 that one is hubbed at front pivot groove 513.
Rear belt pulley 72, is hubbed at rear slide unit 52, and has rear pivot 721 and a trailing wheel portion 722 run through by rear pivot 721 that one is hubbed at rear pivot groove 522.
Belt 73, is set around between the front wheele part 712 of front belt pulley 71 and the trailing wheel portion 722 of rear belt pulley 72, and has first fixing part 731 and being fixed on pedestal 20 and be positioned at the second fixing part 732 above the first fixing part 731.Wherein, the first fixing part 731 is fixed on the fixed block 21 of pedestal 20 by a pedestal belt fixed plate 74.
Middle slide unit 53, the second fixing part 732 being located at each middle slide block 34 and belt 73 has a table top 531 and is positioned at the fixing part 532 of table top 531 both sides.Wherein, the second fixing part 731 of belt 73 is fixed thereon by slide unit belt fixed plate 54 in by middle slide unit 53.
Cover plate 80, be located at pedestal 20 and the table top 531 of covering linear slide rail 30, ball screw 40, front slide unit 51, rear slide unit 52, fixing rod 60, belt 73 and middle slide unit 53, and the fixing part 532 of middle slide unit 53 exposes outside cover plate 80, establishes for other device groups.
The above is structure and the configuration explanation thereof of each main member of first embodiment of the invention.The following description is please refer to as manner of execution of the present invention and effect.
Consult shown in Fig. 3, Fig. 6 to Fig. 9, when screw rod 41 one end is rotated in original place by power plant (figure does not show) connect drive, nut 42 drives front slide unit 51 at screw rod 41 and slide rail 31 top offset, and the front slide unit 51 after displacement more synchronously can drive rear slide unit 52 and middle slide unit 53 displacement, namely, the distance of slide unit 53 and rear slide unit 52 displacement is the distance of nut 42 at screw rod 41 top offset.In addition, design on belt 73 is fixedly arranged on by being provided with belt 73 and middle slide unit 53 between forward and backward slide unit 51,52, forward and backward slide unit 51,52 is in the process of displacement, belt 73 can produce rotation displacement, belt 73 is made to pull middle slide unit 53 and displacement again, therefore, for nut 42 drives the shift length of front slide unit 51 to add, belt 73 rotates the actual displacement distance of middle slide unit 53 pulls the distance of middle slide unit 53 displacement.
Accordingly, the transmission stroke that the present invention needs only needs the long screw rod 41 being about half length to X of pedestal 20, in the processing procedure of screw rod 41, short screw is the half of long bolt material requested, in manufacture, short screw is also than being easier to, smooth and easy, straight degree and to install short screw all convenient than long bolt, and cost and the time of saving are many, and whipping and sagging situation can not occur screw rod 41, so do not need to support.Therefore, the present invention reaches the degree of difficulty reducing the cost of material of screw rod, processing procedure degree of difficulty and correction really, avoids the object that screw rod whipping is possible simultaneously.
Consult shown in Fig. 3, Fig. 6, Fig. 7, front slide unit 51 of the present invention has a front support roller 55 contacted with cover plate 80, rear slide unit 52 has a rear support roller 56 contacted with cover plate 80, and be equipped with fixing rod 60 between forward and backward slide unit 51,52, make the distance of back and front supporting roller 55,56 contact cover plate 60 constant.Therefore, the forward and backward slide unit 51,52 in long-stroke linear module of the present invention can support cover plate 80, avoids cover plate 80 sagging.
Consult shown in Figure 10, a kind of long-stroke linear module that second embodiment of the invention provides, it is primarily of pedestal 20a, ball screw 40a, front slide unit 51a, rear slide unit 52a, fixing rod 60a, front belt pulley 71a, rear belt pulley 72a, belt 73a, middle slide unit 53a and cover plate composition, because its configuration, effect and object are same as the first embodiment, therefore do not repeat them here, after its action as shown in figure 11.Be as the second embodiment and first embodiment's difference:
Front slide unit 51a, is located on nut 42a, and has multiple front wheel 514a contacted with pedestal 20a;
Rear slide unit 52a, is located on pedestal 20a, and has multiple rear roller 523a contacted with pedestal 20a;
Middle slide unit 53a, is located at the second fixing part 732a of belt 73a and has a table top 531a, is arranged in the fixing part 532a of table top 531a both sides and multiple roller 533a contacted with pedestal 20a.
By this, the rear roller 523a on the front wheel 514a directly arranged on front slide unit 51a, middle slide unit 53a on roller 533a and rear slide unit 52a replaces the linear slide rail in the first embodiment, uses to reach another and can implement state.
In sum, above-mentioned two specific embodiments and accompanying drawing are preferred embodiment of the present invention, and be not used to limit the present invention, anyly know above operator, not departing from spirit of the present invention and scope, every equalization done according to the present patent application the scope of the claims changes and modifies, and all belongs to the scope that patent of the present invention contains.
