Consult shown in Fig. 1 to Fig. 6, the linear module of a kind of tool support device that first embodiment of the invention provides, it is mainly made up of pedestal 21, two trunnion mount 22, screw rod 23, two guide rail 24, mobile platform 30, two supporting base 40, roller 50, a connection piece 60 and an enclosing cover 70, wherein this mobile platform 30, each supporting base 40, roller 50 and link 60 form the support device supporting this screw rod 23 and this enclosing cover 70, wherein:
Described pedestal 21 is a long strip pedestal.
Described trunnion mount 22, is installed in this pedestal 21 in a distance.
Described screw rod 23, is arranged between described two trunnion mounts 22; In the present embodiment, this screw rod 23 is driven by a motor 25, makes this screw rod 23 pivotable between described two trunnion mounts 22.
Described two guide rails 24, are installed in this pedestal 21 in parallel to each other, and lay respectively at the both sides of this screw rod 23.
Described mobile platform 30, is placed on this screw rod 23 and can be located at this guide rail 24 with displacement; In the present embodiment, this mobile platform 30 has the platform pivot groove 32 that a platform end face 31 and is located at this platform end face 31, and the opposed slot wall of this platform pivot groove 32 is respectively provided with a groove shoulder 321, this mobile platform 30 has two supporting sliders 33 being slidably installed in respectively this guide rail 24 again.It is worth mentioning that, there is in this mobile platform 30 nut 34 that is sheathed on this screw rod 23, due to this nut 34 and this screw rod 23 configuration and make flowing mode all with known identical, the also emphasis of non-invention, therefore for these components detailed construction with make flowing mode and no longer describe in detail.
Described two supporting bases 40, are placed on this screw rod 23 and can be located at this guide rail 24 with displacement, and laying respectively at the two ends of this mobile platform 30; In the present embodiment, respectively this supporting base 40 all has two supporting sliders 41 being slidably installed in respectively this guide rail 24.
Described roller 50, the platform pivot groove 32 of this mobile platform 30 can be located at rotationally, and have two the first round portion 51, between described two first round portions 51 and wheel footpath 521 is less than this portion 51 first round takes turns second of footpath 511 and take turns portion 52 and and place each this portion 51 and second first round and take turns portion 52 and two ends are separately positioned on the axle portion 53 of this groove shoulder 321; In the present embodiment, the first round portion of this roller 50 51 partly can protrude from this platform end face 31, and this first round portion 51 and the second wheel footpath 511,521 of taking turns portion 52 than for two-to-one, as shown in Figure 7.
Described link 60 is an on-deformable plate body, and has two connecting end portion being installed in described two supporting bases 40 respectively 61 and and second taken turns the connection bottom surface 62 that portion 52 contacts drive by this; In the present embodiment, make this connection bottom surface 62 and this second take turns between portion 52 and can not produce skidding.
Described enclosing cover 70, has two enclosing cover ends being installed in described two trunnion mounts 22 respectively 71 and one and the enclosing cover bottom surface 72 of keeping in touch, this portion 51 first round; In the present embodiment, make between this enclosing cover bottom surface 72 and this portion 51 first round and can not produce skidding, when driving this mobile platform 30 shift reciprocately in order to do making this screw rod 23, this roller 50 rotates forward thereupon or rotates backward.
The above is structure and the configuration explanation thereof of each main member of first embodiment of the invention.Make flowing mode and effect thereof as first embodiment of the invention, be described as follows.
One, are the platform pivot grooves 32 that can be located at this mobile platform 30 rotationally due to described roller 50, and group establish after this first and second take turns portion 51,52 and partly can protrude from this platform end face 31, and protrude from this platform end face 31 this portion 51 first round can contact with the enclosing cover bottom surface 72 of this enclosing cover 70, therefore, this enclosing cover 70 can be supported, avoid this enclosing cover 70 because of long the produced bending phenomenon of length, the mobile platform 30 or the supporting base 40 that reach this enclosing cover 70 of reduction and this linear module produce the object of interfering.
Two, because described mobile platform 30 and described two supporting bases 40 are all placed on this screw rod 23 and can be located at this guide rail 24 with displacement, therefore, avoided this screw rod 23 because of longer the produced bending phenomenon of length, reach the basic demand supporting this screw rod 23, continuous action relation simultaneously between this mobile platform 30 and described two supporting bases 40 only transmits this roller 50 single and this link 60 single reached, therefore form the number of components obviously less compared with case before aforementioned patent, use and reach the object that mechanism is simple, maintenance cost is low.
