[0004] However, the following problems still exist in the current stainless steel plate stacking racks:

[0005] When the above-mentioned device is in use, the stainless steel bar is directly placed on the grinding roller. During this process, the stainless steel bar is only in contact with the grinding roller. As the stainless steel bar is manually conveyed and polished, it is easy for the stainless steel bar to move upward, that is, the stainless steel bar is no longer in close contact with the grinding roller, which makes it difficult to ensure the polishing effect of the stainless steel bar, and it is easy for the grinding to be insufficient and uneven.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figure 1-Figure 5The utility model provides a technical solution: a stainless steel bar polishing machine comprises a workbench 1, a polishing wheel 2 for polishing the bar is arranged on the left front side of the upper end of the workbench 1, a grinding wheel 3 for grinding the bar is arranged on the left rear side of the upper end of the workbench 1, a rotating screw 4 is arranged on the upper plate-shaped structure of the workbench 1, and the rotating screw 4 is connected to the grinding wheel 3 through a pulley, and an adjusting screw 7 is rotatably arranged on the upper plate-shaped structure of the workbench 1, and the adjusting screw 7 is connected to the fixing plate 6 through a threaded hole opened on the fixing plate 6, and a fixing component 8 is arranged on the fixing plate 6, and a pressing wheel 9 is arranged on the fixing component 8; a pushing plate 5 is rotatably arranged on the rotating screw 4, and the pushing plate 5 forms a limiting structure with the workbench 1 through a ball roller arranged at its lower end, and an arc groove is opened on the left and right sides of the workbench 1, and a ball roller is arranged in the spherical groove opened at the lower end of the pushing plate 5 for rolling;

[0023] When the stainless steel bar needs to be polished, the stainless steel bar is placed between the polishing wheel 2 and the grinding wheel 3, and then the pushing plate 5 is tightly fitted with the rear end of the stainless steel bar, and then the polishing wheel 2 and the grinding wheel 3 start to rotate (the polishing wheel 2 and the grinding wheel 3 are both driven to rotate by the motor, and the driving directions of the two motors are opposite, that is, the polishing wheel 2 and the grinding wheel 3 start to rotate in different directions, and the surface roughness of the polishing wheel 2 is greater than the surface roughness of the grinding wheel 3, and the length of the polishing wheel 2 is greater than the length of the grinding wheel 3). At this time, the surface of the stainless steel bar starts to be polished, and the grinding wheel 3 is connected to the rotating screw 4 through a pulley. At this time, the rotating screw 4 starts to rotate. As the rotating screw 4 rotates, the pushing plate 5 starts to push the stainless steel bar to move to the left (the pushing plate 5 is connected to the rotating screw through the threaded hole opened at its upper end 4 are interconnected), at this time, the stainless steel bar can be stably transported while being ground and polished, and as the stainless steel bar is ground, the front side of the stainless steel begins to fit with the pressing wheel 9, and the pressing wheel 9 can be used to press the front side of the stainless steel bar to avoid the uneven grinding caused by the change in the supporting position of the stainless steel bar during the grinding process (as the stainless steel bar moves to the left, the weight of the stainless steel bar on the left side of the grinding wheel 3 begins to increase, that is, the stainless steel is prone to warping during the grinding process, because when the grinding starts, the push plate 5 can support the stainless steel bar to a certain extent, and when the grinding starts, the position of the stainless steel bar is placed more closely to the polishing wheel 2 and the grinding wheel 3, so there will be no warping), ensuring the grinding and polishing effect of the stainless steel bar;

[0024] The fixing assembly 8 includes a receiving plate 801 and a positioning plate 802. The lower end of the receiving plate 801 is connected to the upper end of the fixing plate 6. The positioning plate 802 is slidably connected to the receiving plate 801 through a groove provided on the receiving plate 801. The fixing assembly 8 also includes a pulling spring 803. The pulling spring 803 is connected to the positioning plate 802. The pulling spring 803 is installed on the receiving plate 801. The positioning plate 802 is elastically connected to the receiving plate 801 through the pulling spring 803. The fixing assembly 8 also includes a snap-fit ​​plate 804 and a positioning plate Rod 805, the engaging plate 804 is installed on the plate-like structure provided on the pressing wheel 9, the engaging plate 804 and the groove provided on the receiving plate 801 are mutually fitted, and the plate-like structure provided on the pressing wheel 9 is mutually connected with the positioning rod 805; the fixing assembly 8 also includes a traction plate 806 and a vortex spring 807, the traction plate 806 is mutually fitted with the positioning rod 805 through the arc-shaped groove provided on the upper end thereof, the vortex spring 807 is mutually connected with the lower end of the traction plate 806, and the vortex spring 807 is mutually connected with the fixing rod provided on the side of the fixing plate 6;

[0025] When it is necessary to grind stainless steel bars of different diameters, the adjusting screw 7 is rotated, because the adjusting screw 7 is connected to the fixing plate 6 through the threaded hole opened on the fixing plate 6 (the left end of the fixing plate 6 at the upper end position is connected to the adjusting screw 7, and the right end is connected to the adjusting screw 7 to form a sliding connection, and the right end of the fixing plate 6 at the lower end position is connected to the adjusting screw 7 to form a sliding connection). Therefore, by rotating and adjusting the two adjusting screws 7, the position of the fixing plate 6 can be adjusted, and because a pressing wheel 9 is installed on the fixing plate 6, the purpose of adjusting the pressing wheel 9 can be achieved, that is, it can ensure that stainless steel bars of different diameters are fitted and limited. When it is necessary to disassemble and replace the pressing wheel 9 (the pressing wheel 9 will be worn out as the use time increases, so as to avoid being unable to grind the stainless steel bars The rod material is stably supported), the positioning plate 802 is pulled, so that the two positioning plates 802 begin to move towards each other, and the circular parts of the two positioning plates 802 are set to magnetic materials that can be attracted to each other. At this time, the pulling spring 803 begins to be stretched and deformed, and the positioning plate 802 begins to move away from the locking plate 804 until it is no longer in contact with the upper end of the locking plate 804, and then the traction plate 806 is rotated. Because the traction plate 806 and the fixed plate 6 form a rotating mechanism through the vortex spring 807, therefore, with the rotation of the traction plate 806, the vortex spring 807 begins to be squeezed and deformed, and the traction plate 806 begins to rotate in the direction away from the positioning rod 805 until it is no longer in contact with the positioning rod 805. At this time, the fixed plate 6 can be pulled, so as to achieve the purpose of disassembling and replacing the pressing wheel 9.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
