[0033] As shown in the attached Figures 1-6 A crystal grinding device that is convenient for replacing grinding blocks, which includes a frame 1, a workbench 11, an X-axis transverse movement component 12, a Y-axis transverse movement component 13, and a moving seat 14. The Y-axis transverse movement component 13 is fixed to the frame 1, the moving seat 14 is slidably connected to the frame 1, and the Y-axis transverse movement component 13 moves the moving seat 14 in the Y-axis direction. An X-axis transverse movement component 12 is fixedly installed on the moving seat 14, and a grinding table 15 is also slidably arranged on the moving seat 14. The X-axis transverse movement component 12 moves the grinding table 15 in the X-axis direction. The grinding table 15 includes a grinding device, a movable plate 152, and a Z-axis lifting component 151. The grinding device is installed on the movable plate 152, and the Z-axis lifting component 151 moves the movable plate 152 in the Z-axis direction.

[0034] In this embodiment, the grinding table 15 can be moved in three directions by the X-axis transverse movement assembly 12, the Y-axis transverse movement assembly 13, and the Z-axis lifting assembly 151. The X-axis transverse movement assembly 12, the Y-axis transverse movement assembly 13, and the Z-axis lifting assembly 151 can be electric push rods or pneumatic push rods, etc. Their structures are well-known to those skilled in the art, so they will not be described in detail in this specification.

[0035] The grinding device includes a grinding motor 153 and a grinding block removal assembly. The grinding motor 153 provides power for grinding work. The grinding block removal assembly is used to conveniently replace the grinding block 1546.

[0036] In some embodiments, the grinding block removal assembly includes a connecting seat 1541 and a locking rod 1542. The connecting seat 1541 is provided with a sliding groove 1543. The locking rod 1542 is slidably disposed in the sliding groove 1543. One end of the connecting seat 1541 is slidably provided with a fixing block 1544. The fixing block 1544 is snap-fitted and fixed with a mounting bracket 1545. The mounting bracket 1545 is fixedly connected with a grinding block 1546 through a central locking nut. The connecting seat 1541 is provided with a sliding groove 1543, and the locking rod 1542 can slide in the sliding groove 1543. The design of the sliding groove 1543 allows the locking rod 1542 to move within a certain range, so as to realize the disassembly and installation of the mounting bracket 1545. The number of fixing blocks 1544 is multiple, and they are slidably disposed on the connecting seat 1541 around the locking rod 1542. When the locking rod 1542 moves downward, the fixing blocks 1544 move away from each other, so that the fixing blocks 1544 extend out of the connecting seat 1541, and the fixing blocks 1544 are snap-fitted and fixed with the mounting bracket 1545, thereby fixing the grinding block 1546.

[0037] In some embodiments, a tooth groove 15451 is provided on the inner side wall of the mounting bracket 1545, a first through hole 15452 is provided on the inner bottom wall of the mounting bracket 1545, and the grinding block 1546 is also provided with a second through hole 15462. The first through hole 15452 and the second through hole 15462 are concentrically arranged. One end of the fixing block 1544 is provided with a convex tooth 15441, and the convex tooth 15441 meshes with the tooth groove 15451. When the fixing block 1544 moves to the corresponding position where it is snap-fitted with the mounting bracket 1545, the convex tooth 15441 meshes with the tooth groove 15451, so as to realize the fixation of the mounting bracket 1545 and prevent the mounting bracket 1545 from rotating relative to the connecting seat 1541.

[0038] In some embodiments, a placement groove 111 capable of accommodating the mounting bracket 1545 is provided on the workbench 11. An electric push rod 114 is provided below the placement groove 111. The electric push rod 114 is fixed to the frame 1, and the movable end of the electric push rod 114 penetrates through the placement groove 111, the first through hole 15452, and the second through hole 15462. The diameter of the movable end of the electric push rod 114 is smaller than the diameter of the locking rod 1542. A magnet 112 is further provided on the inner bottom wall of the placement groove 111. The workbench 11 is provided with the placement groove 111, providing a dedicated space for storing multiple mounting brackets 1545. The design of the placement groove 111 ensures that the mounting bracket 1545 has a fixed position when not in use, avoiding damage caused by random placement. A magnet 112 is provided on the inner bottom wall of the placement groove 111. When the mounting bracket 1545 is placed in the placement groove 111, the magnet 112 will adsorb the mounting bracket 1545 to ensure its stable fixation and prevent sliding or displacement. During use, the operator can install grinding blocks 1546 with different mesh numbers on the mounting bracket 1545 and place them in the placement groove 111, thereby improving the replacement efficiency of the grinding blocks 1546.

[0039] In some embodiments, a notch 15421 adapted to the fixing block 1544 is provided at the lower end of the locking rod 1542. A clamping spring 1547 is provided between the fixing block 1544 and the connecting seat 1541, and the clamping spring 1547 always makes the fixing blocks 1544 have a tendency to move closer to each other. When the notch 15421 at the lower end of the locking rod 1542 moves to the corresponding position of the fixing block 1544, the clamping spring 1547 makes the fixing blocks 1544 move in the direction of approaching each other, so that the fixing blocks 1544 retract into the connecting seat 1541, causing the fixing blocks 1544 to be disengaged from the mounting bracket 1545, thereby realizing the unlocking of the mounting bracket 1545.

[0040] In some embodiments, the connecting seat 1541 is fixedly connected to the output end of the grinding motor 153. Through the fixed connection, the vibration and energy loss that may occur during the transmission process are reduced, and the stability and efficiency of the grinding process are improved.

[0041] In some embodiments, a return spring 1548 is provided between the connecting seat 1541 and the locking rod 1542, and the return spring 1548 always makes the locking rod 1542 have a tendency to move downward. When the operator operates the locking rod 1542 for unlocking or locking operations, the return spring 1548 will automatically reset the locking rod 1542 after the operation is completed, ensuring that the locking rod 1542 is always in the correct position. The function of the return spring 1548 ensures that the locking rod 1542 can be accurately reset after each operation, thereby ensuring the stable fixation of the mounting bracket 1545 and avoiding loosening or falling off.

[0042] In some embodiments, a rubber buffer pad 1549 is provided between the mounting bracket 1545 and the grinding block 1546. The rubber buffer pad 1549 can effectively absorb and mitigate the vibration and impact force generated during the grinding process, protect the grinding block 1546 and other components of the device, and extend their service life. By reducing vibration, the rubber buffer pad 1549 helps to improve the stability of the grinding process, thereby enhancing the grinding accuracy and product quality.

[0043] In some embodiments, a clamping seat 113 is provided on the workbench 11. Three screw rods 1131 are threadedly connected inside the clamping seat 113. An arc-shaped clamping member 1132 is rotatably connected to the inner side of the screw rod 1131. Two ends of the outer side of the arc-shaped clamping member 1132 are fixedly connected with slide rods 1133; the slide rods 1133 are slidably connected inside the clamping seat 113. When an operator needs to fix the crystal, first place the crystal to be ground inside the clamping seat 113, and then turn the three screw rods 1131 on the outside. Under the action of the threaded connection, the screw rod 1131 can drive the arc-shaped clamping member 1132 to move in the direction of approaching each other, so that the arc-shaped clamping member 1132 can clamp the crystal.

[0044] The working principle of this utility model is as follows: When an operator needs to grind the crystal, first fix the crystal in the clamping seat 113. By turning the three screw rods 1131 on the outside, under the action of the threaded connection, the screw rod 1131 can drive the arc-shaped clamping member 1132 to move in the direction of approaching each other, so that the arc-shaped clamping member 1132 can clamp the crystal. Subsequently, with the cooperation of the X-axis transverse movement assembly 12, the Y-axis transverse movement assembly 13 and the Z-axis lifting assembly 151, the grinding block 1546 is moved to abut against the crystal. Driven by the grinding motor 153, the grinding block 1546 starts to rotate and grind the crystal. When grinding to a certain extent and it is necessary to replace the grinding block 1546 with a larger mesh number for fine grinding of the crystal. The X-axis transverse movement assembly 12, the Y-axis transverse movement assembly 13 and the Z-axis lifting assembly 151 will drive the movable plate 152 to move above the empty placement groove 111. Subsequently, the Z-axis lifting assembly 151 moves the grinding block removal assembly downward until the grinding block 1546 abuts against the inner bottom wall of the placement groove 111. At this time, the rod body of the electric push rod 114 extends upward. During this process, the locking rod 1542 is pushed upward due to the electric push rod 114, so that the position of the notch 15421 is in the corresponding position of the fixed block 1544. Due to the provision of the notch 15421, the fixed block 1544 moves in the direction of approaching each other under the elastic force of the clamping spring 1547, so that the notch 15421 abuts against the fixed block 1544, thereby the fixed block 1544 is disengaged from the clamping connection with the mounting clip 1545, and the mounting bracket 1545 is in the unlocked state. Immediately afterwards, the Z-axis lifting assembly 151 drives the movable plate 152 to move upward.

[0045] At the same time, the magnet 112 provided on the inner bottom wall of the placement groove 111 has a downward suction force on the mounting bracket 1545 and the grinding block 1546, so as to ensure that when the Z-axis lifting assembly 151 drives the movable plate 152 to move upward, the connecting seat 1541 and the mounting bracket 1545 are smoothly separated.

[0046] Finally, under the cooperation of the X-axis transverse movement assembly 12 and the Y-axis transverse movement assembly 13, the movable plate 152 is moved above the placement groove 111 for placing the mounting bracket 1545 to be replaced, and then the grinding block removal assembly is moved downward by the Z-axis lifting assembly 151. Before that, the electric push rod 114 first extends upward so that the movable end of the electric push rod 114 protrudes from the upper end surface of the mounting bracket 1545. During the downward movement of the grinding block removal assembly, the movable end of the electric push rod 114 abuts against the locking rod 1542, causing the locking rod 1542 to move upward. Since the diameter of the movable end of the electric push rod 114 is smaller than the diameter of the locking rod 1542, the fixing block 1544 can move in the direction of approaching each other under the elastic force of the clamping spring 1547, so that the fixing block 1544 retracts into the connecting seat 1541, and then the lower end of the connecting seat 1541 smoothly abuts against the upper end surface of the mounting bracket 1545. Subsequently, the movable end of the electric push rod 114 moves downward to return to the initial position, so that the locking rod 1542 moves downward under the elastic force of the return spring 1548, causing the fixing block 1544 to move in the direction of moving away from each other, so that the fixing block 1544 is clamped and fixed to the mounting bracket 1545, thereby fixing the grinding block 1546. Finally, the mounting bracket 1545 is in a locked state. The replacement of the grinding block 1546 is completed through the above steps.

[0047] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
