[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] The present invention discloses a grinding machine for grinding irregularly shaped parts. It is mainly used in situations where irregularly shaped parts have some protruding surfaces. When the irregularly shaped parts rotate and come into contact with the grinding wheel, the protruding surfaces make rigid contact with the grinding wheel, which can easily lead to damage to both the grinding wheel and the irregularly shaped parts.

[0024] Reference Figure 1 , Figure 2 and Figure 4 A grinding machine for grinding irregularly shaped parts includes a cabinet 1. A partition 4 is fixedly installed at the lower end of the cabinet 1. A slide rail 5 is fixedly installed on the right side of the cabinet 1. A slidable platform 6 is connected to the outside of the slide rail 5. A slide rod 7 is fixedly installed on the right side of the cabinet 1 at the front and rear ends of the slide rail 5. A first hydraulic rod 8 is fixedly installed on the right side of the slidable platform 6. A grinding table 9 is fixedly installed on the right side of the first hydraulic rod 8. Fixed blocks 10 are fixedly installed at the front and rear ends of the right side of the grinding table 9. A rotating shaft 11 is rotatably connected between the fixed blocks 10. A steel wire grinding wheel 12 is fixedly installed in the middle of the outer side of the rotating shaft 11. A movable groove 13 is formed inside the fixed block 10. A telescopic rod 14 is fixedly installed inside the movable groove 13. A spring 15 is sleeved on the outside of the telescopic rod 14. A push block 16 is fixedly installed on the right side of the telescopic rod 14.

[0025] In this embodiment: When grinding irregularly shaped parts, the slide rail 5 is activated to drive the stabilizing platform 6 to slide on the slide rail 5, adjusting the stabilizing platform 6 to a suitable position. When the slide rail 5 drives the stabilizing platform 6 to slide, the stabilizing platform 6 will also slide on the slide rod 7, improving the stability of the stabilizing platform 6 during sliding. Then, the first hydraulic rod 8 is activated to drive the grinding table 9 to move closer to the irregularly shaped part. The motor is started to drive the rotating shaft 11 to rotate, thereby driving the wire grinding wheel 12 to rotate, realizing the grinding of the irregularly shaped part. After a section of the irregularly shaped part is ground, the slide rail 5 is activated to drive the stabilizing platform 6 to slide, thereby driving the wire grinding wheel 12 to slide up and down. The process involves comprehensive grinding of irregularly shaped parts to reduce grinding dead spots. When the protruding side of the irregularly shaped part suddenly comes into contact with the wire grinding wheel 12 during rotation, the wire grinding wheel 12 is forced to move to the left, and the rotating shaft 11 also moves accordingly, pressing the push block 16, thereby pressing the spring 15. The telescopic rod 14 improves the stability of the push block 16 when sliding. After the contact with the protruding surface ends, the spring 15 returns to its original position, causing the push block 16 to slide to the right, thereby causing the rotating shaft 11 to return to its original position. This avoids the protruding surface of the irregularly shaped part from suddenly making rigid contact with the wire grinding wheel 12 when rotating, which could lead to damage to the wire grinding wheel 12 and the irregularly shaped part.

[0026] Reference Figure 2 , Figure 3 , Figure 5 and Figure 6 In a preferred embodiment, a turntable 17 is rotatably connected to the upper right side of the partition 4. A limiting groove 23 is formed at the upper end of the turntable 17. A double-ended lead screw 24 is rotatably connected inside the limiting groove 23. A limiting block 25 is rotatably connected to the outer side of the double-ended lead screw 24. A clamping block 26 is fixedly installed on the side of the limiting block 25 near the central axis. A rubber pad 27 is adhered to the side of the clamping block 26 near the central axis. A second hydraulic rod 28 is fixedly installed at the top inside the cabinet 1. An installation platform 29 is fixedly installed at the lower end of the second hydraulic rod 28. A pressure plate 30 is rotatably connected to the lower end of the installation platform 29.

[0027] In this embodiment, when grinding irregularly shaped parts, one end of the irregularly shaped part is placed on the turntable 17, and the motor is started to drive the double-ended lead screw 24 to rotate. The rotation of the double-ended lead screw 24 causes the limiting block 25 to slide in the limiting groove 23, so that the clamping block 26 gradually fits against the irregularly shaped part, thereby limiting and locking the irregularly shaped part and improving the stability of the irregularly shaped part during grinding. Then, the second hydraulic rod 28 is started to drive the mounting table 29 to press down, so that the pressure plate 30 fits and presses against the upper end of the irregularly shaped part. Then, the motor is started to drive the turntable 17 to rotate, thereby driving the irregularly shaped part to rotate, which facilitates the comprehensive grinding of the irregularly shaped part and improves the grinding effect.

[0028] Reference Figure 1 , Figure 2 and Figure 6In a preferred embodiment, a cabinet door 2 is rotatably connected to the front end of the cabinet body 1, and a glass plate 3 is fixedly installed in the middle of the interior of the cabinet door 2. A sliding groove 18 is provided on the upper end of the partition 4 at the rear end of the turntable 17. A slider 19 is slidably connected inside the sliding groove 18. A suction hood 20 is fixedly installed on the upper end of the slider 19. An air suction groove 21 is provided on the left side of the suction hood 20. A storage box 22 is fixedly installed on the upper right side of the cabinet body 1.

[0029] In this embodiment: the cabinet door 2 is designed to prevent irregularly shaped parts from falling off during grinding and causing injury to workers. At the same time, the glass plate 3 allows workers to observe the grinding process inside. When installing irregularly shaped parts, the suction hood 20 is rotated, causing the slider 19 to rotate within the slide groove 18. The suction hood 20 is then rotated behind the turntable 17 to prevent it from interfering with the installation of the irregularly shaped parts. A telescopic pipe connects the storage box 22 and the suction hood 20. After the irregularly shaped parts are installed, the suction hood 20 is rotated back to the right side of the turntable 17. During the grinding of the irregularly shaped parts, the air pump is activated, and impurities are sucked up by the suction groove 21 on the suction hood 20 and then enter the storage box 22. This facilitates the centralized collection of debris generated during the grinding process, making it easier to recycle and reuse the debris later.

[0030] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
