Description

Technical Field

[0001] The invention relates to the field of devices designed for grinding rotating surfaces of workpieces, and in particular to a multifunctional stainless steel pipe polishing machine. Background Art

[0002] Stainless steel pipe is a hollow long strip of steel. When producing stainless steel pipe, after the stainless steel pipe is formed, it is usually necessary to polish the stainless steel pipe. This is because polishing can make the surface roughness of the stainless steel pipe reach the specified standard, improve the consistency of product quality and performance, and meet the use requirements; secondly, polishing can remove tiny defects on the surface of the stainless steel pipe (such as scratches, pits, etc.) that may become the starting point of corrosion, and enhance the corrosion resistance of the stainless steel pipe; in addition, polishing can also make the surface of the stainless steel pipe smoother, less likely to adhere to dirt, dust and other impurities, easier to clean, and more beautiful.

[0003] The commonly used stainless steel pipe polishing machine is a centerless polishing machine (also called a centerless grinder). During polishing, the stainless steel pipe is placed between the rotating guide wheel, the rotating polishing wheel and the workpiece support plate. The friction of the guide wheel drives the stainless steel pipe to rotate, and the polishing wheel grinds the rotating surface of the stainless steel pipe for polishing. Obviously, during the processing, the stainless steel pipe is not fixed by the top, and its center position is determined by the workpiece support plate and the guide wheel. Therefore, the stainless steel pipe is prone to slight axial movement during grinding, which will produce slight displacement deviation in the axial direction, thereby affecting the dimensional accuracy of the pipe diameter.

[0057] After being fixed, the telescopic end of the first telescopic member 303 installed on the left side of the inverted U-shaped frame 903 of the front driving assembly begins to extend, driving the driving ring 302 to move backward, and the driving ring 302 drives the three inclined wedges 301 to slide backward in the small circular ring frame 102 located on the front side, and the inclined surface of the inclined wedge 301 squeezes the small connecting plate 403 of the clamping head corresponding to it in the direction of the center of the small circular ring frame 102, and the first reset spring 404 is compressed, and the small connecting plate 403 drives the small roller 401 to move toward the small circular ring frame 102 through the two small straight rods 402. 2, the small rollers 401 of the three clamping heads slide synchronously in the direction of the center of the small circular frame 102, the clamping opening diameter becomes smaller, and the small rollers 401 simultaneously contact the outer surface of the stainless steel pipe to be processed. After the stainless steel pipe to be processed is clamped, the telescopic end of the first telescopic member 303 stays at this length. At the same time, the telescopic end of the first telescopic member 303 installed on the left side of the inverted U-shaped frame 903 of the rear driving assembly is also extended to this length, so that the clamping opening of the clamping member of the small circular frame 102 located at the rear side is also maintained at this size.

[0058] While adjusting the size of the clamping opening, the telescopic end of the second telescopic member 603 is gradually shortened, and the substrate 5 is driven to rise through the driving plate 604. When the substrate 5 rises, the polishing member 7 and the square frame 904 are driven to rise synchronously. The square frame 904 drives the capped rod 905 to rise, and the second reset spring 906 is gradually stretched. The top of the polishing wheel 701 is always in the same plane as the top of the advancing lower roller 901. Therefore, when the top of the advancing lower roller 901 contacts the outer surface of the stainless steel tube to be processed, it also means that the top of the subsequent polishing wheel 701 can also contact the outer surface of the stainless steel tube to be processed.

[0059] After the clamping position is debugged, the mechanical arm is no longer needed to support the stainless steel pipe to be processed. If the stainless steel pipe is super long, adding some external support will make it more stable. The third motor 10012, the first motor 204, and the second motor 801 are started synchronously.

[0060] After the third motor 10012 is started, the output shaft of the third motor 10012 drives the rotating shaft 1002 in the front drive assembly to rotate, and the rotating shaft 1002 in the front drive assembly drives the rotating shaft 1002 in the rear drive assembly to rotate. When the rotating shaft 1002 rotates, it drives the first bevel gear 1003 to rotate, and the first bevel gear 1003 drives the second bevel gear 1005 to rotate. The second bevel gear 1005 drives the first belt groove gear 1004 to rotate through the axle of the first belt groove gear 1004, and the first belt groove gear 1004 drives The second belt groove gear 1006 and the third belt groove gear 1007 rotate, the third belt groove gear 1007 drives the third pulley 1008 to rotate through the second belt 1009, the third pulley 1008 drives the axle of the forward lower roller 901 to rotate, so that the forward lower roller 901 rotates, the second belt groove gear 1006 drives the fourth pulley 10010 to rotate through the third belt 10011, the fourth pulley 10010 drives the axle of the backward upper roller 902 to rotate, so that the backward upper roller 902 rotates. At this time, the forward lower roller 901 is in contact with the outer surface of the stainless steel pipe to be processed, so as the forward lower roller 901 rotates, the stainless steel pipe to be processed is transported backwards and gradually approaches the polishing wheel 701.

[0061] After the first motor 204 is started, the output shaft of the first motor 204 drives the first gear 203 on the left side of the positive U-shaped frame 201 located on the front side to rotate, the first gear 203 drives the gear ring 202 to rotate, the gear ring 202 drives the large circular frame 101 to rotate, and the large circular frame 101 drives the stainless steel pipe to be processed to rotate through the clamping piece on the small circular frame 102. At the same time, the first gear 203 on the right side of the positive U-shaped frame 201 located on the front side drives the first gear 203 on the right side of the positive U-shaped frame 201 located on the rear side to rotate, and the first gear 203 on the right side of the positive U-shaped frame 201 located on the rear side drives the large circular frame 101 located on the rear side to rotate through the gear ring 202, so that the two large circular frames 101 rotate synchronously.

[0062] After the second motor 801 is started, the output shaft of the second motor 801 drives the second pulley 803 to rotate, the second pulley 803 drives the first pulley 802 to rotate through the first belt 804, and the first pulley 802 drives the axle of the polishing wheel 701 to rotate, thereby rotating the polishing wheel 701. When the front end of the stainless steel pipe to be processed contacts the polishing wheel 701, the polishing wheel 701 polishes its surface.

[0063] The driving assembly 9 drives the stainless steel pipe to continue to be transported backwards, and the front end of the stainless steel pipe gradually extends into the clamping opening of the clamping piece of the small circular frame 102 located at the rear side and is clamped. The deformation of the first return spring 404 can cause the clamping opening to deform briefly so that the front end of the stainless steel pipe passes through and is clamped. Subsequently, the front end of the stainless steel pipe contacts the forward lower roller 901 of the rear driving assembly.

[0064] When the rear end of the stainless steel tube leaves the polishing wheel 701, polishing is completed, the first motor 204 and the second motor 801 are turned off, the stainless steel tube no longer rotates, the polishing wheel 701 also no longer rotates, the telescopic end of the second telescopic member 603 gradually extends, and drives the base plate 5 to descend through the driving plate 604. When the base plate 5 descends, the polishing member 7 and the frame 904 are driven to descend synchronously, and they no longer contact the outer surface of the stainless steel tube. The rotation direction of the output shaft of the third motor 10012 is changed to the opposite direction, thereby driving the backward upper roller 902 and the forward lower roller 901 to reverse. Therefore, when the bottom of the backward upper roller 902 contacts the outer surface of the stainless steel tube, the backward The upper roller 902 drives the polished stainless steel pipe to be transported forward. When the front end of the stainless steel pipe is about to leave the clamping opening of the clamping piece of the small circular ring frame 102 located on the front side, the polished stainless steel pipe is supported by a mechanical arm, and the third motor 10012 is turned off. The telescopic end of the first telescopic piece 303 is gradually shortened, driving the three inclined wedges 301 to move away from the center point of the substrate 5, and the first return spring 404 gradually returns to the natural extension state, driving the small connecting plate 403, the two small straight rods 402 and the small roller 401 to slide in the direction away from the center of the small circular ring frame 102, and the diameter of the clamping opening becomes larger. At this time, the mechanical arm can take out the polished stainless steel pipe.

[0065] It should be noted that the present invention is not limited to the specific structures shown in the drawings in the above-mentioned embodiments, and various changes can be made thereto within the knowledge scope of ordinary technicians in this field.
