[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0020] Please see Figures 1-4 The present invention provides the following two preferred embodiments:
[0021] Example 1: A grinding machine depth adjuster, comprising: a protective sleeve 2, the protective sleeve 2 being fixedly installed on the outside of the cutter wheel on the grinding machine body 1; a guide block 3 being fixedly installed on one side of the protective sleeve 2 and a fixing block 4 being fixedly installed on the other side; the bottom surface of the guide block 3, the bottom surface of the fixing block 4, and the axis of the cutter wheel of the grinding machine body 1 being located on the same plane; characterized in that: the protective sleeve 2 is provided with an adjustment component and a fixing component; the guide hole 5 in the adjustment component is opened at the bottom end of the guide block 3, the bottom end of the fixing block 4 is provided with a positioning hole 6, and the pad 7 is provided with a cutter hole 8 for the cutter wheel of the grinding machine body 1 to pass through; the two ends of the side wall of the pad 7 are respectively fixedly provided with a positioning post 9 and a guide rod 10, the positioning post 9 being inserted into the positioning hole 6, the guide rod 10 being inserted into the guide hole 5, a scale strip 11 being fixedly embedded on the side wall of the guide rod 10, and a limit plate 12 being threadedly connected to the end of the guide rod 10.
[0022] During use, the guide rod 10 is moved along the guide hole 5 while the positioning pin 9 moves in the positioning hole 6, allowing the grinding machine body 1's cutting wheel to pass through the cutting hole 8. The end of the guide rod 10 is threadedly connected to the limiting plate 12 to prevent the pad 7 from falling off during use. The position of the pad 7 is adjusted according to the cutting depth requirements of the material line pipe. The reading indicator scale 11 is exposed on the bottom side of the guide hole 5 to control the distance from the bottom of the pad 7 to the axis of the grinding machine body 1's cutting wheel, thereby controlling the depth at which the grinding machine body 1's cutting wheel is exposed in the cutting hole 8. After that, the position of the positioning pin 9 is fixed to fix the pad 7. During cutting, the pad 7 contacts the outer wall of the material line pipe to limit the cutting, that is, to control the cutting depth of the grinding machine. The operation is simple and quick, avoiding damage to the pipe fittings inside the material line pipe during cutting.
[0023] Example 2: Based on Example 1, the circular groove 13 in the fixing component is formed on the side wall of the fixing block 4. A stud 14 is movably disposed in the circular groove 13, and a fixing post 15 is fixedly disposed on the side wall of the stud 14. The diameter of the fixing post 15 is smaller than the diameter of the stud 14. The fixing post 15 is movably disposed in the circular groove 13. A slot 16 is formed on the peripheral wall of the fixing post 15. The positioning post 9 is movably engaged in the slot 16. One end of the slot 16 is arc-shaped. Anti-slip ridges 17 are provided in the arc surface of the slot 16. The anti-slip ridges 17 are engaged with the positioning post 9. A lever plate 18 is fixedly disposed on the side wall of the stud 14, and a knob nut 19 is rotatably disposed on the side wall of the fixing block 4. The knob nut 19 is threadedly connected to the stud 14.
[0024] During use, after the pad 7 is positioned, rotate the knob nut 19 to control the stud 14 to move outward within the circular groove 13 until the positioning post 9 moves to the arc end of the slot 16, so that the periphery of the positioning post 9 is tightly engaged with the anti-slip ridge 17 to achieve anti-slip fixation. This fixes the position of the positioning post 9, limits the pad 7, and thus controls the cutting depth of the grinder. The operation is simple and quick. At the same time, if the scale strip 11 or the anti-slip ridge 17 wears during use, the limit plate 12 can be unscrewed to separate the positioning post 9 from the slot 16 and unscrew the stud 14. Then, the pad 7 with the new scale strip 11 and the fixing post 15 with the new anti-slip ridge 17 can be replaced to further ensure the accuracy of controlling the cutting depth. During installation, use the lever 18 to rotate the stud 14 to assist the positioning post 9 in inserting into the slot 16 on the fixing post 15.
[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
