Usually, the polishing operation of stainless steel bars is carried out by an automatic polishing machine. The existing automatic polishing machine is the equipment used for polishing during the processing and production of stainless steel bars. It is convenient to rotate the stainless steel bar and adjust the polishing plate to contact the surface of the stainless steel bar for polishing.

[0003] Existing automatic grinding machines, when grinding stainless steel bars, directly close the end of the stainless steel bar inside the fixed cylinder connected to the end of the rotary motor and cylinder, and then use tools to rotate multiple fixing bolts to press and fix it on the surface of the stainless steel bar. Therefore, the operation is inconvenient during fixing and installation, and the bolt ends are prone to causing severe stress on the outer surface of the stainless steel bar during installation, resulting in damage. Conversely, the same operation is still cumbersome to disassemble, thus affecting the convenience of fixing, installation and protection of automatic grinding machines when processing and grinding stainless steel bars. To address this, this utility model proposes an automatic grinding machine for stainless steel bars. Utility Model Content

The stainless steel rod is moved again by the movement of the auxiliary cylinder 104, so that the other end of the stainless steel rod is engaged inside the internal threaded fixing cylinder 106 connected to the end of the rotary motor 108. The stainless steel rod and the internal threaded fixing cylinder 106 are fixedly installed again. The internal threaded fixing cylinder 106 and the stainless steel rod are rotated by the rotary motor 108 and contact the inner surface of the grinding plate 105 for grinding.

[0024] The front surface of the main housing 101 is provided with a protective door 102. A lead screw 1012 rotates at the top of the interior of the main housing 101. A forward / reverse motor 1011 is fixed to the end of the lead screw 1012 on the side of the main housing 101. A movable seat 1013 is provided on the outer surface of the lead screw 1012. The bottom end of the movable seat 1013 is connected to the upper surface of the mounting plate 109 via a main cylinder. A collection box 103 is fixed to the bottom of the interior of the main housing 101. During grinding, the movable seat 1013 can be moved on the outer surface of the lead screw 1012, causing the mounting plate 109 and the grinding plate 105 to move laterally, facilitating grinding of different positions on the outer surface of the stainless steel bar. The automatic grinding machine body 100 is also equipped with:

[0025] The convenient fixing and installation mechanism includes a rotary adjustment component disposed inside the internally threaded fixing cylinder 106. A clamping and fixing component is disposed on the inner surface of the rotary adjustment component. A sliding control component is disposed at the connection between the bottom end of the clamping and fixing component and the bottom end of the internal threaded fixing cylinder 106. When the automatic grinding machine body 100 grinds and fixes the stainless steel rod, the end of the stainless steel rod is conveniently fixed and installed to the inside of the internally threaded fixing cylinder 106 through the convenient fixing and installation mechanism. The installation is convenient and is not prone to squeezing damage.

[0026] In order to facilitate the pressing, moving, clamping, and fixing of the outer arc-shaped clamping plate 1063 by means of the rotation adjustment component, in this embodiment, preferably, the rotation adjustment component includes an externally threaded hollow ring 1061 with its threads rotating inside the internally threaded fixing cylinder 106. The top edge of the externally threaded hollow ring 1061 is fixed with a toggle button 1062, which is convenient to hold and move the externally threaded hollow ring 1061 inside the internally threaded fixing cylinder 106 by hand, and to press and move the externally arc-shaped clamping plate 1063 by the rotation of the externally threaded hollow ring 1061.

[0027] To facilitate the quick and convenient installation of the stainless steel rod inside the internally threaded fixing cylinder 106 using a clamping and fixing assembly, in this embodiment, preferably, the clamping and fixing assembly includes an outer arc-shaped clamping plate 1063 disposed on both sides inside the internally threaded fixing cylinder 106. A friction plate 1064 is provided on the inner surface of the outer arc-shaped clamping plate 1063. An inner arc-shaped surface 1067 is formed at the bottom end of the inner surface of the outer threaded hollow ring 1061, and the inner arc-shaped surface 1067 matches the outer surface structure of the outer arc-shaped clamping plate 1063. This allows the outer arc-shaped clamping plate 1063 to be pressed and moved by the inner arc-shaped surface 1067 when the outer threaded hollow ring 1061 rotates, thus clamping and fixing the friction plate 1064 onto the surface of the stainless steel rod, facilitating installation.

[0028] In order to facilitate the stable compression and movement of the outer arc-shaped clamping plate 1063 by means of the sliding control component, in this embodiment, preferably, the sliding control component includes two limiting slide rods 1065 fixed to the bottom of the inner threaded fixing cylinder 106. A limiting slider 1066 slides on the outer surface of the limiting slide rod 1065. The upper surface of the limiting slider 1066 is fixed to the bottom of the outer arc-shaped clamping plate 1063 by welding. When the outer arc-shaped clamping plate 1063 is compressed and moved, the limiting slider 1066 is driven to slide on the outer surface of the limiting slide rod 1065 to control the movement, so that the outer arc-shaped clamping plate 1063 can move stably for compression and fixing installation.

[0029] The stabilization mechanism includes a stabilization sliding component disposed at the connection between the mounting plate 109 and the main housing 101. A uniform force support component is disposed at the connection between the end of the grinding plate 105 and the outer surface of the stabilization sliding component. The stabilization mechanism can stably control and support the automatic grinding machine body 100 during grinding by adjusting the mounting plate 109 and the grinding plate 105.

[0030] To facilitate stable adjustment and grinding of the mounting plate 109 and grinding plate 105 using a stabilizing sliding assembly, in this embodiment, preferably, the stabilizing sliding assembly includes control slide rods 1052 welded and fixed to both sides inside the main housing 101. Slide sleeves 1053 are fitted onto the outer surface of the control slide rods 1052. A support crossbar 1051 is welded to the connection point of the two slide sleeves 1053. When the main cylinder drives the mounting plate 109 to rise and fall, it also drives the support crossbar 1051 to rise and fall, causing the end of the support crossbar 1051 to slide the slide sleeves 1053 on the outer surface of the control slide rods 1052. A sliding hole 1054 is provided inside the mounting plate 109, and the support crossbar 1051 passes through the sliding hole 1054, allowing it to slide on the outer surface of the support crossbar 1051 through the sliding hole 1054 during lateral movement, facilitating stable sliding operation.

[0031] In order to facilitate stable support and grinding of the ends of the mounting plate 109 and the grinding plate 105 by means of a uniform force support assembly, in this embodiment, preferably, the uniform force support assembly includes a reinforcing support body 1055 fixedly installed at both ends of the mounting plate 109 by bolts, and the supporting crossbar 1051 passes through the interior of the reinforcing support body 1055. When the mounting plate 109 and the grinding plate 105 can be moved down and moved laterally for grinding, the reinforcing support body 1055 can slide on the outer surface of the supporting crossbar 1051 to stably support the mounting plate 109 and the grinding plate 105 for uniform force grinding.

[0032] The working principle and usage process of this utility model are as follows: When using this automatic stainless steel bar grinding machine, the main body 100 of the automatic grinding machine is first placed stably in the processing operation position. During operation, one end of the stainless steel bar is closed inside the internal threaded fixing cylinder 106 connected to the end of the mounting base 107. Then, the stainless steel bar is moved by the movement of the auxiliary cylinder 104, so that the other end of the stainless steel bar is engaged inside the internal threaded fixing cylinder 106 connected to the end of the rotary motor 108. The stainless steel bar and the internal threaded fixing cylinder 106 are fixedly installed again. The internal threaded fixing cylinder 106 and the stainless steel bar are rotated by the rotation of the rotary motor 108. At this time, the main cylinder moves to drive the mounting plate 109 and the grinding plate 105 to move down to contact the outer surface of the stainless steel bar for rotational grinding. Then, the forward and reverse motor 1011 drives the lead screw 1012 to rotate. When the lead screw 1012 rotates, it drives the moving base 1013 to move on the outer surface of the lead screw 1012, thereby driving the grinding plate 105 to move laterally on the outer surface of the stainless steel bar for grinding.

[0033] Then, before the automatic grinding machine body 100 is used for grinding, when the end of the stainless steel rod is closed inside the internal thread fixing cylinder 106 and installed, the end of the stainless steel rod can be passed through the external thread hollow ring 1061 and extended into the internal thread fixing cylinder 106. At this time, the hand-held toggle button 1062 drives the external thread hollow ring 1061 to rotate inside the internal thread fixing cylinder 106. When the external thread hollow ring 1061 rotates, it contacts the outer surface of the external arc clamp 1063 through the inner arc surface 1067 and presses it inward. At the same time, when the external arc clamp 1063 moves, the bottom end drives the limiting slider 1066 to slide on the outer surface of the limiting slider 1065, so that the external arc clamp 1063 moves stably and drives the friction plate 1064 to clamp and fix it on the outer surface of the stainless steel rod. Thus, the stainless steel rod is quickly rotated and fixed inside the internal thread fixing cylinder 106. The installation is convenient and it is not easy to squeeze and damage the surface of the stainless steel rod, which improves the convenience of fixing, installation and protection of the automatic grinding machine body 100 when processing and grinding stainless steel rods.

[0034] Finally, when the automatic grinding machine body 100 is grinding, the main cylinder drives the mounting plate 109 to rise and fall, thereby driving the support crossbar 1051 to rise and fall. This causes the end of the support crossbar 1051 to slide on the outer surface of the control slide bar 1052 via the sliding sleeve 1053, ensuring stable support for the mounting plate 109 and the grinding plate 105. As the mounting plate 109 moves laterally, the support crossbar 1051 slides on the outer surface of the support crossbar 1051 via the sliding hole 1054. The end of the mounting plate 109 is slidable and supported on the outer surface of the support crossbar 1051 by the reinforcing support body 1055, so that the ends of the mounting plate 109 and the grinding plate 105 can be stably slidably controlled. This makes it easier to move and adjust the mounting plate 109 and the grinding plate 105 more stably for grinding. It also makes the operation more stable when the grinding force is applied, and it is not easy to shake or become unstable. This improves the stability control of the mounting plate 109 and the grinding plate 105 by the main body 100 of the automatic grinding machine when processing and grinding stainless steel bars.
