DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 4 The utility model provides a technical solution: a diamond grinding wheel with a positioning support structure, comprising an outer wheel sleeve 1, an inner mounting wheel 2 and a support mechanism 3,

[0022] An inner mounting wheel 2 is arranged inside the outer wheel sleeve 1, and a supporting mechanism 3 is arranged on the inner side of the outer wheel sleeve 1. The supporting mechanism 3 is composed of a scissors support arm 31, an extension layer 32, a reserved groove 33, a plug-in groove 34, abutment block 35, a first magnetic block 36, a second magnetic block 37 and a mounting base plate 38. The scissors support arm 31 is rotatably installed in the groove inside the inner mounting wheel 2 through a connecting column, one side of the scissors support arm 31 is connected to the extension layer 32, and the other side of the scissors support arm 31 is provided with a reserved groove 33.

[0023] The outer wheel sleeve 1 has equidistantly provided plug-in grooves 34 inside, a mounting base plate 38 is plugged into the bottom of the inner mounting wheel 2, a contact block 35 and a first magnetic block 36 are installed on the upper side of the mounting base plate 38, the vertical cross-section of the contact block 35 is trapezoidal, one side of the contact block 35 and the inside of the inner mounting wheel 2 are both installed with the first magnetic block 36, the extension layer 32 and the adjacent reserved groove 33 are both installed with the second magnetic block 37, and the upper side of the inner mounting wheel 2 is connected with a mounting column 4.

[0024] During specific implementation, in order to facilitate the rapid replacement of the edging wheel, the edging wheel is assembled in a manner that the outer wheel sleeve 1 and the inner mounting wheel 2 can be installed and disassembled. The inner mounting wheel 2 is first plugged into the outer wheel sleeve 1 by plugging. After the plugging is completed, the positioning mechanism 5 is used to position and install the mounting base 38. At this time, the abutment block 35 on the upper side of the mounting base 38 presses the scissor support arm 31 upward to open the extension layer 32 and the reserved groove 33 that were originally in the plug-in state. After the scissor support arm 31 is fully unfolded, it is plugged into the plug-in groove 34 inside the outer wheel sleeve 1. At this time, under the action of the abutment block 35, the scissor support arm 31 plays a supporting and plugging effect in the plug-in groove 34 of the outer wheel sleeve 1, and squeezes and limits the outer wheel sleeve 1. At this time, the mounting column 4 can be installed and connected to the grinder;

[0025] The upper side of the mounting base plate 38 and the first magnetic block 36 in the inner mounting wheel 2 have a mutual attraction effect, thereby enhancing the squeezing and opening effect of the abutment block 35 and the first magnetic block 36 on the scissor support arm 31. When the second magnetic block 37 is used to replace the outer wheel sleeve 1, the mounting base plate 38 is moved downward through the positioning mechanism 5 until the abutment block 35 and the first magnetic block 36 are no longer connected to the scissor support arm 31. The scissor support arm 31 will automatically close under the action of the extension layer 32 and the second magnetic block 37 in the reserved groove 33, so as to facilitate the removal of the outer wheel sleeve 1. The diamond grinding wheel with a positioning support structure is provided with a support mechanism 3. The support mechanism 3 can quickly open and close under the action of the positioning mechanism 5, and effectively limit the support of the outer wheel sleeve 1, which is convenient to operate.

[0026] See also Figure 1 and Figure 2It can be seen that a positioning mechanism 5 is arranged on the upper side of the mounting base plate 38, and the positioning mechanism 5 is composed of a groove 51, a mounting knob 52, a rotational connection layer 53, a positioning screw 54, a docking layer 55, a docking groove 56 and a threaded groove 57. A groove 51 is provided at the bottom of the mounting base plate 38, and a mounting knob 52 is provided inside the groove 51. The mounting base plate 38 is connected to a docking layer 55 on one side close to the abutment block 35. The slide groove provided inside the docking layer 55 is rotationally connected to the positioning screw 54 through the rotational connection layer 53. A docking groove 56 and a threaded groove 57 are provided inside the inner mounting wheel 2, and the threaded groove 57 is located above the docking groove 56.

[0027] When the positioning mechanism 5 is used, the mounting knob 52 in the groove 51 is rotated, and the mounting base plate 38 is slowly pushed upward until the docking layer 55 on the upper side of the mounting base plate 38 is plugged into the docking groove 56 at the bottom of the inner mounting wheel 2. When the positioning screw 54 and the threaded groove 57 are threadedly connected, the end of the abutment block 35 close to the docking layer 55 will be plugged into the positioning groove inside the inner mounting wheel 2 to prevent the mounting base plate 38 from shaking. At the same time, the mounting base plate 38 and the interior of the docking layer 55 are rotationally connected with the positioning screw 54 through the rotating connection layer 53, which can effectively prevent the connection between the positioning screw 54 and the threaded groove 57 from loosening. The diamond grinding wheel with a positioning support structure is provided with a positioning mechanism 5, which can quickly complete the positioning installation of the mounting base plate 38, and the effect of preventing the positioning screw 54 from loosening is significant, and the installation is convenient.

[0028] To sum up, when using the diamond grinding wheel with a positioning support structure, the inner mounting wheel 2 is plugged into the outer wheel sleeve 1 by plugging, the mounting knob 52 in the groove 51 is turned, and the mounting base plate 38 is slowly pushed upward. When the positioning screw 54 and the threaded groove 57 are threadedly connected, the abutment block 35 on the upper side of the mounting base plate 38 squeezes the scissor support arm 31 upward to open it. At this time, under the action of the abutment block 35, the scissor support arm 31 plays a supporting and plugging effect in the plug-in groove 34 of the outer wheel sleeve 1, and the outer wheel sleeve 1 is squeezed and limited.
