Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and do not limit the present utility model.

[0017] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0018] Please see Figure 1 and Figure 4 This utility model provides a reinforcing structure for mounting a grinding wheel, the reinforcing structure for mounting a grinding wheel includes: The grinding wheel body 1 and the galvanized iron cover 2 are fixed inside the grinding wheel body 1 to provide stable support for the grinding wheel body 1. The galvanized iron cover 2 has a threaded hole and a positioning hole in the middle, with the positioning hole distributed on both sides of the threaded hole. The mounting mechanism 3 is threadedly connected to the galvanized iron cover 2 through the threaded hole and passes through the positioning hole. The mounting mechanism 3 is threadedly connected to a rotating rod 4, which has a positioning groove and a cavity. The rotating rod 4 is sleeved on the mounting mechanism 3 through the positioning groove. The reinforcing mechanism 5 is installed on the rotating rod 4 to lock the mounting mechanism 3 to reinforce the installation of the grinding wheel.

[0019] When installing the grinding wheel, the mounting mechanism 3 is passed through the positioning hole in the galvanized iron cover 2 and the positioning groove in the rotating rod 4. Then, the mounting mechanism 3 is screwed into the rotating rod 4 until it is tightened. The reinforcing mechanism 5 then locks the mounting mechanism 3 in place, completing the installation and reinforcement of the grinding wheel body 1. Connecting the rotating rod 4 to the output shaft of the motor controls the rotation of the grinding wheel body 1. For disassembly, the operation is reversed: the mounting mechanism 3 is unscrewed, and the control end of the reinforcing mechanism 5 is rotated to push the mounting mechanism 3 outward, allowing for quick disassembly of the grinding wheel body 1. The entire process is simple and efficient.

[0020] like Figure 1 , Figure 2 and Figure 3As shown, in a preferred embodiment of the present invention, the installation mechanism 3 includes: a positioning rod 31, which passes through the positioning hole opened in the galvanized iron cover 2; a rotating rod 4 is sleeved on the positioning rod 31 through a positioning groove; the positioning rod 31 has a locking groove and a disc 32 is fixedly connected to its end; the disc 32 has a round hole; a fixing bolt 33, which passes through the round hole through the disc 32 and is connected to the galvanized iron cover 2 through a threaded hole; the rotating rod 4 and the fixing bolt 33 are threadedly connected.

[0021] When installing the grinding wheel body 1, the positioning rod 31 on the disc 32 is passed through the positioning hole opened in the galvanized iron cover 2 and the positioning groove opened in the rotating rod 4. Then, the fixing bolt 33 is screwed into the threaded hole and the rotating rod 4 until the fixing bolt 33 is tightened. At the same time as the fixing bolt 33 is tightened, both ends of the reinforcing mechanism 5 are also inserted into the locking groove opened in the positioning rod 31 to form a double locking, thereby reinforcing the grinding wheel body 1 and ensuring that the grinding wheel body 1 is stable and reliable when rotating at high speed.

[0022] like Figure 2 As shown, in a preferred embodiment of this utility model, the reinforcing mechanism 5 includes: a central rod 51, which is fixedly installed in the cavity opened by the rotating rod 4, a base 52 is fixedly installed on the central rod 51, a handle 53 extending out of the cavity is rotatably installed on the base 52, and a cam 54 is fixedly installed on the handle 53; an outward pushing component 55, which is installed in the cavity opened by the rotating rod 4 and sleeved on the central rod 51, with locking rods 56 fixedly connected to both ends of the outward pushing component 55, the locking rods 56 extending into the positioning groove, and the outward pushing component 55 is used to push the locking rods 56 into the locking groove to reinforce the positioning rod 31; and an ejection component 57, which is fixedly installed in the positioning groove opened by the rotating rod 4, and is used to push the positioning rod 31 outward when the grinding wheel body 1 is disassembled.

[0023] As the fixing bolt 33 is tightened, the positioning rod 31 is gradually inserted. The arc design at the front end of the positioning rod 31 ensures that it can overcome the obstruction of the locking rod 56. When the locking groove of the positioning rod 31 and the locking rod 56 are fully engaged, the push assembly 55 can push the locking rod 56 to be firmly locked into the locking groove, thereby strengthening the grinding wheel body 1 and ensuring the stability and reliability of the grinding wheel body 1 during high-speed rotation. When removing the grinding wheel body 1, first unscrew the fixing bolt 33, turn the handle 53 to control the cam 54 to rotate, so that the push assembly 55 can drive the locking rod 56 out of the locking groove. The ejection assembly 57 can push the positioning rod 31 outward a certain distance, and the positioning rod 31 can then be pulled out from the positioning hole and positioning groove, and the grinding wheel body 1 can be easily disassembled. This design not only improves the convenience of installing and disassembling the grinding wheel body 1, but also further enhances the safety of the grinding wheel body 1 by strengthening the installation of the grinding wheel body 1, and extends the service life of the equipment.

[0024] like Figure 2 As shown, in a preferred embodiment of this utility model, the push-out assembly 55 includes: a guide rod 551, whose two ends are fixedly connected to the inner wall of the cavity opened by the rotating rod 4; a partition plate 552 is fixedly provided in the middle of the guide rod 551; guide plates 553 are provided on both sides of the partition plate 552 and sleeved on the guide rod 551; a locking rod 56 is fixedly connected to the guide plate 553; and a push spring 554 for pushing the locking rod 56 into the locking groove is fixed between the guide plate 553 and the partition plate 552; and a linkage block 555, which is sleeved on the central rod 51; a synchronizing rod 556 is hinged to the linkage block 555; and the end of the synchronizing rod 556 away from the linkage block 555 is hinged to the guide plate 553.

[0025] When the locking groove of the positioning rod 31 and the locking rod 56 are fully engaged, the push spring 554 can push the guide plates 553 on both sides and the locking rod 56 away from each other along the guide rod 551. The locking rod 56 can then be embedded into the locking groove, thereby reinforcing the installation of the grinding wheel body 1. When the grinding wheel body 1 is removed, after the fixing bolt 33 is unscrewed, the throttle handle 53 is turned to control the cam 54 to rotate. The cam 54 pushes the linkage block 555 to move to the right along the center rod 51. The linkage block 555 can then cause the synchronizing rod 556 to drive the guide plate 553 and the locking rod 56 to retract. The locking rod 56 exits from the locking groove, and the ejector assembly 57 pushes the positioning rod 31 outward a certain distance, thereby allowing the positioning rod 31 to be removed. The grinding wheel body 1 can then be disassembled smoothly. The whole process is simple and efficient, ensuring safe operation.

[0026] like Figure 2 As shown, in a preferred embodiment of the present invention, the ejector assembly 57 includes: a sleeve 571, which is fixed in the positioning groove opened in the rotating rod 4; a sleeve rod 572 is slidably disposed on the sleeve 571; an ejector plate 573 is fixedly disposed on the sleeve rod 572; and a top spring 574, whose two ends are respectively fixedly connected to the ejector plate 573 and the sleeve 571 and sleeved on the sleeve rod 572, for pushing the positioning rod 31 outward by the ejector plate 573.

[0027] After the locking rod 56 is removed from the locking groove, under the elastic force of the top spring 574, the ejector plate 573 drives the sleeve rod 572 to slide along the sleeve 571. The movement of the ejector plate 573 can push the positioning rod 31 outward a certain distance, thereby ensuring that the positioning rod 31 is smoothly removed from the positioning groove, and realizing the unobstructed disassembly of the grinding wheel body 1.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
