Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] For purposes of simplicity and illustration, the principles of the embodiments are described primarily by way of example. In the following description, numerous specific details are set forth to provide a thorough understanding of the embodiments. However, it will be apparent to those skilled in the art that these embodiments may not be limited to these specific details in practice. In some instances, well-known methods and structures have not been described in detail to avoid unnecessarily obscuring these embodiments. Furthermore, all embodiments can be used in combination with each other. Example

[0032] Please see Figures 1 to 10 This invention provides a technical solution: a grinding structure replacement system, comprising a quick-change mounting plate 1 for the grinding structure, a grinding structure mounting bracket 2 disposed below the quick-change mounting plate 1; a main shaft 11 fixedly mounted at the upper center of the quick-change mounting plate 1, a quick-change dial 12 fixedly mounted at the center of the main shaft 11, a rotating shaft 21 rotatably mounted at the center of one side inner wall of the grinding structure mounting bracket 2, and a grinding wheel 3 disposed on the outside of the rotating shaft 21; a servo motor 13 disposed on one side of the main shaft 11, a dial wheel 14 fixedly mounted on the output shaft of the servo motor 13, the outer side of the dial wheel 14 being adapted to the outer side of the quick-change dial 12; a grinding wheel retaining ring 31 is engaged at the center of the grinding wheel 3, and the inner surface of the grinding wheel retaining ring 31 is threadedly connected to the outer surface of the rotating shaft 21;

[0033] The quick-change mounting plate 1 for grinding structure is rotatably mounted on the vertical gear grinding machine platform 4 via the main shaft 11. Four sets of grinding structure mounting brackets 2 can be installed below the quick-change mounting plate 1. Grinding wheels 3 can be installed in the middle of each set of grinding structure mounting brackets 2. The servo motor 13 drives the actuating wheel 14 to rotate, which in turn rotates the quick-change dial 12, causing the main shaft 11 to rotate and drive the quick-change mounting plate 1 to rotate. This enables the quick-change of grinding wheels 3 below the grinding structure mounting brackets 2 to be changed quickly. The grinding wheels 3 are rotatably mounted on the rotating shaft 21 in the middle of the grinding structure mounting bracket 2 via a grinding wheel fixing ring 31. The grinding wheel fixing ring 31 can be removed by rotating it to replace the grinding wheels 3. This solves the problem that existing gear grinding machines can only install one set of grinding wheels on the servo motor, and the need to use tools to replace the grinding wheels is very inconvenient. The quick-change of grinding wheels can be achieved by adding a grinding structure. Example

[0034] See attached document Figures 8 to 10Based on Embodiment 1, in order to achieve a tighter installation of the grinding wheel 3 on the rotating shaft 21, this embodiment adds a grinding wheel auxiliary fixing mechanism 8 on the outside of the grinding wheel 3. The grinding wheel auxiliary fixing mechanism 8 includes a locking fixing plate 81 that is snapped onto one end of the rotating shaft 21. The inner surface of the locking fixing plate 81 is snapped onto the outer surface of the grinding wheel fixing ring 31. A pressing fixing plate 82 is provided on the outside of the locking fixing plate 81. The outer wall of the locking fixing plate 81 is provided with a movable groove that matches the pressing fixing plate 82. A threaded adjusting rod 83 is fixedly installed on the outside of the pressing fixing plate 82. The outer surface of the threaded adjusting rod 83 is threadedly connected to the side wall of the grinding structure mounting bracket 2. A damping spring 84 is provided between the outer surface of the pressing fixing plate 82 and the inner surface of the grinding structure mounting bracket 2.

[0035] After the grinding wheel retaining ring 31 is snapped into the middle of the grinding wheel 3, the grinding wheel retaining ring 31 is rotated to install it on the rotating shaft 21 and tightened. Then, the locking retaining plate 81 is snapped into the rear end of the rotating shaft 21 to support the outer side of the grinding wheel retaining ring 31. The threaded adjusting rod 83 is rotated to make the pressing retaining plate 82 snap into the movable groove at the rear end of the locking retaining plate 81. This will not prevent the rotating shaft 21 from driving the locking retaining plate 81 and the grinding wheel 3 to rotate and grind as a whole. At the same time, the pressing retaining plate 82 presses the locking retaining plate 81 to further ensure that the grinding wheel 3 is installed more tightly on the rotating shaft 21. The damping spring 84 buffers the vibration generated by the grinding wheel 3 during grinding. This further solves the problem that the existing gear grinding machine's servo motor can only install one set of grinding wheels, and the grinding wheel needs to be replaced with tools, which is very inconvenient. The grinding wheel can be quickly replaced by adding a grinding structure. Example

[0036] See attached document Figures 8 to 10 Based on Embodiment 2, an anti-slip mechanism 9 is added. The anti-slip mechanism 9 includes a lever 91 that is symmetrically hinged to the inner wall of the grinding structure mounting frame 2. A locking block 92 is fixedly installed at one end of the lever 91. The side wall of the pressing fixing plate 82 is provided with a slot that matches the locking block 92. Limiting telescopic spring rods 93 are movably installed on the outer side of the lever 91. The upper ends of the limiting telescopic spring rods 93 are respectively hinged to the inner wall of the grinding structure mounting frame 2.

[0037] After the pressing fixed plate 82 is installed and engaged with the locking fixed plate 81, the lever 91 is moved to lock the locking block 92 against the upper and lower ends of the side wall of the pressing fixed plate 82. The limiting telescopic spring rod 93 provides oblique support to the side wall of the lever 91, making the pressing fixed plate 82 stable and continuously pressing the locking fixed plate 81, so that the grinding wheel 3 is tightly installed. This further solves the problem that the existing gear grinding machine can only install one set of grinding wheels on the servo motor, and the grinding wheel needs to be replaced with tools, which is very inconvenient. The grinding wheel can be quickly replaced by adding a grinding structure. Example

[0038] See attached document Figures 1 to 10 Based on Embodiment 3, this embodiment proposes a CNC vertical gear grinding machine that facilitates the replacement of the grinding structure. It includes a vertical gear grinding machine platform 4, with a CNC device 41 externally connected to one side of the platform. A workpiece mounting bracket 43 is welded to the front end of the platform. A grinding structure mounting bracket 42 is fixedly mounted on the upper surface of the platform. A servo motor 13 is fixedly mounted on the upper surface of the grinding structure mounting bracket 42. The outer surfaces of the actuating wheel 14 and the spindle 11 are rotatably connected to the inner top wall of the grinding structure mounting bracket 42. A grinding drive structure mounting bracket 5 is fixedly installed on the lower side. A telescopic rod 51 is fixedly installed at the rear end of the grinding drive structure mounting bracket 5. A grinding servo motor mounting plate 52 is fixedly installed at the output end of the telescopic rod 51. A grinding servo motor 53 is fixedly installed on the rear side of the grinding servo motor mounting plate 52. A rotating bushing 54 is rotatably installed on the front side of the grinding servo motor mounting plate 52. The output shaft of the rotating bushing 54 passes through the inner wall of the grinding servo motor mounting plate 52 and is fixedly connected to the output shaft of the grinding servo motor 53. The inner wall of the rotating bushing 54 is provided with a slot that matches the rear end of the rotating shaft 21.

[0039] The CNC equipment 41 can control the gear grinding machine and the grinding structure. The grinding structure mounting bracket 42 serves to mount the grinding drive structure mounting bracket 5 and the grinding structure mounting bracket 2. The grinding drive structure mounting bracket 5 is installed on one side of the grinding structure mounting bracket 42, with a distance set to allow sufficient space for the grinding structure mounting bracket 2 to rotate. The telescopic rod 51 at the rear end of the grinding drive structure mounting bracket 5 controls the extension and movement of the grinding servo motor mounting plate 52, so that the rotating bushing 54 installed at the front end of the grinding drive structure mounting bracket 5 can engage with the rotating shaft 21. Driven by the grinding servo motor 53, the shaft rotates... The bushing 54 drives the rotating shaft 21 to rotate, thereby rotating the grinding wheel 3 to perform the grinding action. The telescopic rod 51 controls the retraction and movement of the grinding servo motor mounting plate 52, so that the rotating bushing 54 installed at the front end of the grinding drive structure mounting frame 5 is disengaged from the rotation range of the grinding structure mounting frame 2. This does not obstruct the rotation of the grinding structure mounting frame 2, enabling quick replacement of the grinding wheel 3. This further solves the problem that existing gear grinding machines can only install one set of grinding wheels on the servo motor, and that replacing the grinding wheel requires the use of tools, which is very inconvenient. By adding a grinding structure, the effect of quick replacement of the grinding wheel can be achieved. Example

[0040] See attached document Figures 1 to 10 Based on Embodiment 3, this embodiment proposes that a workpiece mounting platform 6 is fixedly installed above the workpiece mounting frame 43. A guide rail 61 is fixedly installed on the outer side of the upper surface of the workpiece mounting platform 6. A threaded rod 62 is rotatably installed on the inner side of the upper surface of the workpiece mounting platform 6. A servo motor 63 is fixedly installed at one end of the workpiece mounting platform 6. The output shaft of the servo motor 63 is fixedly connected to one end of the rotating shaft of the threaded rod 62. A workpiece moving platform 7 is slidably installed on the inner side of the guide rail 61. A telescopic top rod 71 is fixedly installed on one side of the workpiece moving platform 7. A movable top plate 72 is fixedly installed at the output end of the telescopic top rod 71. A fixed clamping plate 73 is fixedly installed on one side of the upper surface of the movable top plate 72. A clamping telescopic rod 74 is fixedly installed on the outer side of the fixed clamping plate 73. A telescopic groove adapted to the clamping telescopic rod 74 is provided on the lower inner wall of the fixed clamping plate 73. A movable clamping piece 75 is fixedly installed at the output end of the clamping telescopic rod 74. The movable clamping piece 75 is located on the inner side of the fixed clamping plate 73.

[0041] In this embodiment, the servo motor 63 drives the threaded rod 62 to rotate, causing the workpiece moving table 7 to move under the limiting cooperation of the guide rail 61, thereby realizing the saw blade grinding and tooth-grinding function. The telescopic top rod 71 can lift the movable top plate 72, so that the saw blade workpiece mounted on the movable top plate 72 contacts the grinding wheel 3 for grinding. The clamping telescopic rod 74 retracts, causing the movable clamping plate 75 to move closer to the fixed clamping plate 73 to clamp the saw blade workpiece. The installation is convenient. It is worth noting that the workpiece mounting table 6 is fixed to the workpiece mounting frame 43 by bolts and can be disassembled. Therefore, other clamping fixtures can be replaced and installed on the workpiece mounting frame 43 to realize the grinding treatment of other parts that need grinding, such as gears, on the vertical gear grinding machine platform 4. Example

[0042] This embodiment proposes a method for using a CNC vertical gear grinding machine that facilitates the replacement of grinding structures, including the following steps:

[0043] Step 1: After snapping the grinding wheel retaining ring 31 into the middle of the grinding wheel 3, rotate the grinding wheel retaining ring 31 to install it on the rotating shaft 21 and tighten it. Then, snap the retaining plate 81 onto the rear end of the rotating shaft 21 to support the outer side of the grinding wheel retaining ring 31. Rotate the threaded adjusting rod 83 to make the pressing retaining plate 82 snap into the movable groove at the rear end of the pressing retaining plate 81. After the pressing retaining plate 82 is installed and snapped into the pressing retaining plate 81, move the lever 91 to make the locking block 92 lock the upper and lower ends of the side wall of the pressing retaining plate 82.

[0044] Step 2: The telescopic rod 51 at the rear end of the grinding drive structure mounting bracket 5 controls the grinding servo motor mounting plate 52 to extend and move, so that the rotating bushing 54 installed at the front end of the grinding drive structure mounting bracket 5 can engage the rotating shaft 21. Driven by the grinding servo motor 53, the rotating shaft 21 is rotated by the rotating bushing 54 to test and realize the rotation of the grinding wheel 3 before installing the workpiece.

[0045] Step 3: Install the workpiece between the fixed clamping plate 73 and the movable clamping plate 75. The clamping telescopic rod 74 retracts to bring the movable clamping plate 75 closer to the fixed clamping plate 73 to clamp the saw blade workpiece. The servo motor 63 drives the threaded rod 62 to rotate, causing the workpiece moving table 7 to move under the limiting cooperation of the guide rail 61, realizing the saw blade grinding tooth processing function. The telescopic top rod 71 can lift the movable top plate 72 so that the saw blade workpiece installed on the movable top plate 72 contacts the grinding wheel 3 for tooth grinding.

[0046] Step 4: When the grinding wheel 3 needs to be removed after grinding, the workpiece is removed. The telescopic rod 51 controls the grinding servo motor mounting plate 52 to retract and move, so that the rotating bushing 54 installed at the front end of the grinding drive structure mounting frame 5 is disengaged from the rotation range of the grinding structure mounting frame 2. The servo motor 13 can drive the dial wheel 14 to rotate and turn the quick change dial 12 to make the spindle 11 rotate and drive the grinding structure quick change mounting plate 1 to rotate, so as to quickly replace the grinding wheel 3 under the grinding structure mounting frame 2. For the grinding wheel 3 that needs to be removed, turn the dial rod 91 to remove the locking block 92, and rotate the threaded adjustment rod 83 in the opposite direction to make the pressing fixing plate 82 disengage from the locking fixing plate 81. After removing the locking fixing plate 81, rotate the grinding wheel fixing ring 31 to remove the grinding wheel fixing ring 31 and replace the grinding wheel 3.

For those skilled in the art, all applications utilizing the concept of this application are protected as long as various variations are within the spirit and scope of this application as defined and determined by the appended claims.
