Description

Technical Field

[0001] The utility model relates to the technical field of grinders, in particular to a grinder convenient for overhaul and maintenance. Background Art

[0002] A grinder is an essential tool in a machinery factory and has a relatively high usage rate. It is a common device used to grind various cutting tools and tools. It mainly consists of a base, a grinding wheel, an electric motor or other power sources, a bracket, a protective cover, a water feeder, etc. There are mainly bench grinders, vertical grinders, dust-removing grinders, hand-held grinders, hanging grinders, etc.

[0003] Among them, the grinding wheel and the protective cover of the grinder will come into contact with materials and debris. Both are vulnerable parts and need to be overhauled and maintained regularly. However, the existing grinders generally fix the grinding wheel and the protective cover with multiple bolts, and a wrench needs to be used to disassemble them one by one during replacement, which is rather troublesome to operate.

[0004] Therefore, a grinder convenient for overhaul and maintenance is proposed. Summary of the Utility Model

[0024] Such as Figures 1 to 4As shown, a grinding machine that is easy to inspect and maintain includes a base 1, a motor 2 is fixedly installed on the top surface of the base 1, a rotating shaft 3 is fixedly connected to the output end of the motor 2, a grinding wheel 4 is arranged at the end of the rotating shaft 3, a protective shell 5 is arranged outside the grinding wheel 4, a support seat 6 is fixedly connected to the top surface of the base 1, a locking mechanism 7 for limiting the protective shell 5 is arranged on the surface of the support seat 6, and a docking assembly 9 for limiting the grinding wheel 4 is installed on the inner wall of the protective shell 5. More specifically, the motor 2 is operated to drive the rotating shaft 3 and the grinding wheel 4 to rotate, so that the grinding operation can be carried out. When the grinding wheel 4 or the protective shell 5 needs to be replaced, the protective shell 5 is released by the locking mechanism 7, the protective shell 5 is pulled to the right, and then the protective shell 5 is pulled upward to make it detached from the surface of the support seat 6, so that the protective shell 5 is disassembled, and in the process of the protective shell 5 moving to the right, the limit of the grinding wheel 4 by the docking assembly 9 is released, so that the grinding wheel 4 is quickly disassembled.

[0025] The locking mechanism 7 includes a positioning ring 701, and the positioning ring 701 is fixedly connected to the left side of the protective shell 5, and the positioning ring 701 is movably connected to the surface of the support seat 6, a retaining ring 702 is fixedly connected to the surface of the support seat 6, and the top surface of the retaining ring 702 is fitted with the bottom surface of the positioning ring 701, the inner wall of the support seat 6 is rotatably connected to a double-headed screw 703, the surface of the double-headed screw 703 is threadedly connected to an insertion rod 704, and the insertion rod 704 is movably connected to the support seat 6, a slot is provided on the inner wall of the positioning ring 701, and the inner wall of the slot is movably connected to the end of the insertion rod 704, a sliding column 705 is fixedly connected to the inner wall of the support seat 6, and the surface of the sliding column 705 is slidably connected to the insertion rod 704, and the locking mechanism 7 also includes an adjustment component for controlling the rotation of the double-headed screw 703. It should be noted that the double-headed screw 703 is controlled to rotate by the adjusting component, and the insertion rod 704 is driven to slide along the surface of the sliding column 705 under the action of the thread, and finally the end of the insertion rod 704 is separated from the inner wall of the slot, thereby releasing the limit on the positioning ring 701, pulling the protective shell 5 to the right, driving the positioning ring 701 to move to the right, and at the same time allowing the docking component 9 to release the limit on the grinding wheel 4, and then pulling the protective shell 5 upward, driving the positioning ring 701 to no longer contact the retaining ring 702 and separate from the top of the support seat 6, and the protective shell 5 can be disassembled.

[0026] The adjustment assembly includes a worm 706, and the worm 706 is rotatably connected to the support seat 6, a rotating disk 707 is fixedly connected to the top of the worm 706, a worm wheel 708 is fixedly sleeved in the middle of the double-headed screw 703, and the worm wheel 708 is meshed with the worm 706. More specifically, the rotating disk 707 is rotated to drive the worm 706 to rotate, and the worm 706 will drive the worm wheel 708 meshed with it to rotate, thereby controlling the double-headed screw 703 to rotate.

[0027] The docking assembly 9 includes a rotating seat 901, and the rotating seat 901 is rotatably connected to the right side of the inner wall of the protective shell 5, the left end of the rotating seat 901 is fixedly connected to a fixed block 902, the left side of the fixed block 902 is fixedly connected to a pin shaft 903, a mounting hole 904 is opened in the middle of the grinding wheel 4, and the inner wall of the mounting hole 904 is slidably connected to the pin shaft 903, the right end of the rotating shaft 3 is fixedly connected to a fixed plate 905, the surface of the fixed plate 905 is opened with a positioning hole 906, and the inner wall of the positioning hole 906 is movably plugged into the end of the pin shaft 903. It should be noted that when the protective shell 5 slides to the left, it will drive the rotating seat 901 and the fixed block 902 to move, so that the pin shaft 903 can pass through the inner wall of the mounting hole 904, and finally the end of the pin shaft 903 is inserted into the alignment hole 906, so that the grinding wheel 4 and the fixed plate 905 and the fixed block 902 can fit tightly, thereby limiting the grinding wheel 4. When disassembly is required, pull the protective shell 5 to the right to drive the rotating seat 901 to move, so that the rotating seat 901 is separated from the inner wall of the mounting hole 904 and the alignment hole 906, and the limit can be released.

[0028] There are multiple pins 903, mounting holes 904 and alignment holes 906, and the multiple pins 903, mounting holes 904 and alignment holes 906 are distributed in a circular array. More specifically, multiple pins 903, mounting holes 904 and alignment holes 906 are arranged in an array, thereby improving the stability of the grinding wheel 4.

[0029] The surface of the rotating shaft 3 is sleeved with a support bearing 8, and the support bearing 8 is embedded in the support seat 6. It should be noted that during the rotation of the rotating shaft 3, the support bearing 8 provides enhanced support for the rotating shaft 3, so that the rotation of the rotating shaft 3 is more stable.

[0030] In summary: by running the motor 2, driving the rotating shaft 3 and the grinding wheel 4 to rotate, the grinding operation can be carried out. When the grinding wheel 4 or the protective shell 5 needs to be replaced, the limit on the protective shell 5 is released through the locking mechanism 7, and the protective shell 5 is pulled to the right and then pulled upward to make it separate from the surface of the support seat 6, thereby disassembling the protective shell 5. In the process of moving the protective shell 5 to the right, the limit on the grinding wheel 4 by the docking assembly 9 will be released, thereby quickly disassembling the grinding wheel 4. During use, the effect of facilitating the quick disassembly of the grinding wheel and the protective cover is achieved, and the disassembly can be completed without the aid of tools. The operation is more convenient and efficient, which effectively improves the inspection and maintenance efficiency.
