Said driving mechanism 2 comprises variable-frequency motor 21, drive pulley 22, driven pulley 23, belt 24 and main shaft 25; Said variable-frequency motor 21 is installed on the said machine tool main body 1; Output is connected with said drive pulley 22; Said main shaft 25 is articulated on the said machine tool main body 1 and an end is connected with said driven pulley 23, and the other end is connected with said chuck 31, and said belt 24 is wound on said drive pulley 22 and the driven pulley 23.Drive said drive pulley 22 and driven pulley 23 through said variable-frequency motor 21, rotate thereby drive said main shaft 25, and then driving is held on the screw rod 200 on the said chuck 31; Screw rod 200 is rotated; Utilize said variable-frequency motor 21 to realize infinitely variable speeds, thereby simplify traditional speed-changing gear box, greatly save the space; Simple in structure, Operation and Maintenance is very convenient.
As shown in Figure 2; Said burnishing device 4 comprises mounting bracket 41, motor 42, driving wheel 43, driven pulley 44, guide wheel 45, abrasive band 46, horizontal mobile mechanism 47, tensioning apparatus 48 and elastic parts 49; Said horizontal mobile mechanism 47 can be connected on the said machine tool main body 1 with moving horizontally; Said mounting bracket 41 is articulated on the said horizontal mobile mechanism 47; Said motor 42 is installed on the said mounting bracket 41 and output is connected with said driving wheel 43, and said driving wheel 43, driven pulley 44 and guide wheel 45 are articulated in respectively on the said mounting bracket 41, and said abrasive band 46 is wound on said driving wheel 43, driven pulley 44 and the guide wheel 45.
Said horizontal mobile mechanism 47 comprises axis of guide 47a and linear bearing 47b, and said axis of guide 47a flatly is installed on the said mounting bracket 41, and said linear bearing 47b is socketed on the said axis of guide 47a.Utilize said linear bearing 47b straight line on said axis of guide 47a to move, said burnishing device 4 is moved around on the length direction of said screw rod 200, realize whole screw rod 200 polished.
Said tensioning apparatus 48 is a cylinder, and the cylinder body of said cylinder is fixed on the said mounting bracket 41, and the piston rod output of said cylinder and said driven pulley 44 articulate.Said abrasive band 46 is wound between said driving wheel 43, driven pulley 44 and the guide wheel 45, is installing or during demolition, utilizes the Telescopic of the piston rod of said cylinder to make 44 pairs of abrasive bands of said driven pulley 46 carry out tensioning or loosen, thereby makes things convenient for the abrasive band to install or demolition.
Said elastic parts 49 comprises guide pillar 49a and compression spring 49b; Said guide pillar 49a is fixed on the said mounting bracket 41; Said compression spring 49b is socketed on said guide pillar 49a last and an end and 41 conflicts of said mounting bracket, and the other end and said horizontal mobile mechanism 47 are conflicted.When 4 pairs of screw rods 200 of said burnishing device polish; Said burnishing device 4 must rotate and make said abrasive band 46 press close to said screw rod 200 surfaces; After polishing is accomplished, need leave said screw rod 200 surfaces again, therefore, utilize the elastic-restoring force of said elastic parts 49; Can make said burnishing device 4 automatically revert to the state before using, the operation utmost point is convenient.
Comprehensive above-mentioned and combine Fig. 3, the operation principle in the face of the utility model screw rod specialized high-speed polishing machine 100 is described in detail down, as follows:
Before the polishing, with said screw rod 200 horizontal positioned, an end of said screw rod 200 is held on the said chuck 31; Promote said thimble dolly 33 again; Said thimble dolly 33 is moved along said guide rail 11, thereby make said thimble 32 contact at the other end of said screw rod 200, said screw rod 200 is in stationary state; Said control system controls said variable-frequency motor 21 and starts; Said variable-frequency motor 21 rotates and drives said drive pulley 22 and driven pulley 23, thereby drives said main shaft 25 and chuck 31, and said screw rod 200 is rotated.Simultaneously, the motor 42 of said burnishing device 4 starts, and drives said driving wheel 43 and rotates; Because said abrasive band 46 is wound between said driving wheel 43, driven pulley 44 and the guide wheel 45, therefore said driving wheel 43 drives said abrasive band 46 and rotates, at this moment; Manually press said burnishing device 4; Said abrasive band 46 is close to said screw rod 200 surfaces, at this moment, the said compression spring 49b of said mounting bracket 41 compressions.At this moment, promptly polish the screw channel surface of said screw rod 200 in said abrasive band 46.In addition; Can promote said burnishing device 4; Said linear bearing 47b is moved on said axis of guide 47a, thereby make abrasive band 46 on the said burnishing device 4, thereby polish in other places that move to said screw rod 200 when rotated along with the screw channel of screw rod 200 moves horizontally.After having polished, discharge said burnishing device 4, because the restoring force effect of said compression spring 49b, said burnishing device 4 upwards rotates along its articulated section, makes abrasive band 46 leave said screw rod 200 surfaces and can stop polishing.When said abrasive band 46 uses a period of times to change, control said cylinder, make in the piston rod indentation cylinder body of said cylinder through said control system; And then drive said driven pulley 44 and retreat; Thereby said abrasive band 46 is loosened, can take off replacing, the piston rod of changing the said cylinder of back control stretches out cylinder body; And then promote to move on the said driven pulley 44, thereby the said abrasive band 46 of tensioning can continue to use.
Certainly; Said horizontal mobile mechanism 47 also can be combined by servomotor and ball wire bar pair; Utilize said servomotor and said ball wire bar pair that said burnishing device is moved around on the length direction of said screw rod automatically, thereby realize automatic polishing, be not described in detail at this.
Because the utility model utilizes the end clamping of said chuck 31 with said screw rod 200, said thimble 32 contacts at the other end of said screw rod 200, thereby makes said screw rod 200 horizontal positioned; Again the said abrasive band 46 on the said burnishing device 4 is contacted on the surface of said screw rod 200,, make the surface finish of said abrasive band 46 at said screw rod 200 through driving wheel 43 and driven pulley band 44 moving said abrasive bands 46; And utilize horizontal mobile mechanism 47 on the length direction of said screw rod 200, to move around and drive moving around of whole burnishing device 4; Thereby solve the irremovable problem of general polishing machine fuselage, realize whole screw rod 200 polished, manually polish with traditional thousand pages of wheels of use and compare; The utility model uses abrasive band 46 can effectively reduce the dust that polishing produces; Effectively improve production environment, and only need manually press down said burnishing device 4 and can realize automatic polishing, operate very simple and convenient; Production efficiency is greatly improved, and has saved a large amount of production costs.
The control method of the control system that the utility model screw rod specialized high-speed polishing machine 100 is involved is well known to those of ordinary skill in the art, no longer does detailed explanation at this.
The above disclosed preferred embodiments that is merely the utility model can not limit the interest field of the utility model certainly with this, so according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
