[0025] The following is a more detailed description of the grinding wheel unloading and lifting tooling of the present invention, with reference to schematic diagrams, which illustrate preferred embodiments of the present invention. It should be understood that those skilled in the art may modify the present invention described herein while still achieving the advantageous effects of the present invention. Therefore, the following description should be understood as being generally known to those skilled in the art and not as limiting the present invention.

[0026] The following paragraphs describe the present invention in more detail by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description and claims. It should be noted that the drawings are greatly simplified and not to exact scale, and are intended solely to facilitate and clearly illustrate the embodiments of the present invention.

[0027] like Figures 1 to 3 As shown, the embodiment of the utility model proposes a grinding wheel unloading and lifting tool, which includes an elastic lifting ring 1, a crank arm 2, a grinding wheel chuck 3, a connecting screw 4 and a disassembly screw 5.

[0028] Specifically, the crank arm 2 is installed on the elastic hanging ring 1 , and the crank arm 2 is used to connect the elastic hanging ring 1 and the grinding wheel chuck 3 .

[0029] The grinding wheel chuck 3 is fixedly arranged at one end of the crank arm 2 away from the elastic hanging ring 1 , and the grinding wheel chuck 3 is used to connect and fix the grinding wheel 15 .

[0030] The connecting screw 4 is provided through the grinding wheel chuck 3 , and the end of the connecting screw 4 is threadedly connected to the grinding wheel 15 .

[0031] The disassembly screw 5 is threadedly mounted on the grinding wheel chuck 3 , and the end of the disassembly screw 5 abuts against the mounting shaft of the grinding wheel.

[0032] In this embodiment, when installing the grinding wheel of the roll grinder, the position of the grinding wheel chuck 3 is adjusted, and the connecting screw 4 is threaded into the hole of the grinding wheel 15, thereby achieving a quick connection and installation between the grinding wheel chuck 3 and the grinding wheel 15. When removing the grinding wheel 15 from the grinding machine spindle 16, the disassembly screw 5 is rotated, and the disassembly screw 5 abuts against the grinding machine spindle. As the disassembly screw 5 is continuously screwed in, the thrust of the disassembly screw 5 on the grinding machine spindle increases, causing the grinding wheel 15 and the grinding wheel chuck 3 to separate from the grinding machine spindle, completing the removal of the grinding wheel 15.

[0033] In one embodiment, the grinding wheel chuck 3 has a conical positioning groove 6. When the grinding wheel chuck 3 is inserted into the grinding machine spindle 16, the axis of the positioning groove 6 of the grinding wheel chuck 3 gradually approaches and coincides with the axis of the grinding machine shaft. At this time, the connecting screw 4 can be docked with the hole on the grinding wheel, and the grinding wheel chuck 3 can be quickly connected to the grinding wheel.

[0034] Furthermore, the elastic lifting ring 1 includes a lifting and mounting sleeve 7 , a hanging column 8 , a lifting ring 9 and a shock-absorbing spring 10 .

[0035] Specifically, the installation sleeve 7 is penetrated by a movable cavity 11 that matches the suspension column 8 .

[0036] The end of the hanging column 8 is movably arranged in the movable cavity 11, and the end of the mounting sleeve 7 is provided with a retaining ring 12 for limiting the position of the hanging column 8.

[0037] The lifting ring 9 is fixedly mounted on one end of the hanging column 8 away from the mounting sleeve 7 .

[0038] The shock absorbing spring 10 is arranged between the end of the suspension column 8 and the suspension ring, and the shock absorbing spring 10 is used to elastically connect the suspension column 8 and the retaining ring 12.

[0039] In this embodiment, the damping spring 10 is sleeved onto the outer wall of the suspension post 8 and is in contact with and sliding against the inner wall of the active cavity 11. The suspension post 8 is elastically connected to the mounting sleeve 7. During installation of the grinding wheel, the installer can vertically adjust the grinding wheel chuck 3 and the grinding wheel to align the grinding wheel with the axis of the grinding machine spindle, facilitating installation. Furthermore, because the damping spring 10 has a certain buffering effect, it can also reduce the impact force of the grinding wheel with external objects during installation, thus providing a certain degree of protection.

[0040] The lifting ring 9 is rotatably mounted on the suspension column 8. During the installation and removal of the grinding wheel, the grinding wheel chuck 3 can be rotated, which is convenient for installing and removing the grinding wheel in different scenarios.

[0041] Furthermore, a mounting hole 13 matching the crank arm 2 is provided at one end of the mounting sleeve 7 away from the suspension column 8 , and an end of the crank arm 2 passes through the mounting hole 13 and is provided with a fastening handle 14 .

[0042] Specifically, the crank arm 2 is rotatably connected to the inner wall of the mounting hole 13 and is secured within the mounting hole 13 via the fastening handle 14. The crank arm 2 is rotatably mounted within the mounting hole 13 and can rotate vertically, facilitating adjustment of the position of the grinding wheel chuck 3 and the grinding wheel, thereby facilitating installation and removal of the grinding wheel. Furthermore, once the crank arm 2 is positioned correctly, the fastening handle 14 is locked, preventing the crank arm 2 from rotating, allowing for stable installation and removal of the grinding wheel.

[0043] Compared with the prior art, the present invention has at least the following beneficial effects:

[0044] The utility model utilizes the connecting screw 4 and the disassembly screw 5 to realize the rapid disassembly of the grinding wheel. At the same time, the elastic lifting ring 1 can reduce the collision force during the disassembly of the grinding wheel chuck 3, thereby effectively protecting the grinding wheel. The utility model has the characteristics of simple structure and convenient operation.

[0045] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
