Detailed Implementation

[0020] This utility model provides a grinding stone device. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit the scope of protection of this utility model.

[0021] Please see Figures 1-2 This utility model provides a grinding device, including a frame 1, a worktable 2 set on the frame 1 for placing samples, a slide 3 set on the frame 1, a lifting frame 4 set on the slide 3, a grinding machine 51 set on the lifting frame 4, a grinding head 52 connected to the grinding machine 51, a first moving mechanism 6 for driving the slide 3 to reciprocate along the front-back direction of the frame 1, a second moving mechanism 7 for driving the lifting frame 4 to reciprocate along the height direction of the slide 3, and a rotary pressing cylinder 8 set on the worktable 2 for pressing samples.

[0022] In practical use, the sample to be ground is placed on the worktable 2, and the rotary clamping cylinder 8 is activated, causing the pressure rod 84 to rotate to a position above the sample. The pressure rod 84 then presses down, clamping the sample to ensure it does not move during processing. Through the continuous operation of the first moving mechanism 6 and the second moving mechanism 7, the slide 3 and the lifting frame 4 are displaced, causing the grinding head 52 to move to the processing position. The grinding machine 51 is activated, driving the grinding head 52 to rotate at high speed to grind the sample surface. During grinding, the feed rate of the grinding head 52 is changed by altering the position of the slide 3 or the lifting frame 4 to ensure grinding accuracy. Once the sample surface reaches the required dimensional accuracy or surface finish, the grinding machine 51 stops working, and the pressure rod 84 of the rotary clamping cylinder 8 releases the clamping force applied to the sample, allowing the processed sample to be removed.

[0023] In the aforementioned grinding equipment, the first moving mechanism 6 enables the slide 3 to move along the front-back direction of the frame 1; the second moving mechanism 7 enables the lifting frame 4 to move along the up-down direction of the slide 3, thereby driving the grinding head 52 to move back-to-back and up-down; in addition, the rotary clamping cylinder 8, through the rotation, lifting or pressing of the upper pressure rod 84 of the rotary clamping cylinder 8, realizes the loosening or clamping of the sample, so that the grinding equipment can realize multi-axis motion and can also be used for grinding processing needs of samples of different thicknesses.

[0024] In some embodiments, the rotary clamping cylinder 8 includes a base 81 disposed on the upper surface of the worktable 2, a cylinder body 82 fixed to the upper surface of the base 81, a connecting rod 83 that is throttle-connected to the upper surface of the cylinder body 82 and extends laterally, a pressure rod 84 detachably connected to the end of the connecting rod 83, and a pressure plate 85 disposed on the lower surface of the pressure rod 84; the pressure plate 85 is used to contact the upper surface of the sample. Before sample loading, the output end of the rotary clamping cylinder 8 is in an extended state, and the pressure plate 85 is located beside the sample, providing space for sample loading. After sample loading is completed, the connecting rod 83 drives the pressure rod 84 and the pressure plate 85 to rotate, so that the pressure plate 85 is located above the sample. Then, the output end of the rotary clamping cylinder 8 begins to retract, driving the pressure plate 85 to gradually move downward until the lower surface of the pressure plate 85 is in close contact with the upper surface of the sample. In addition, since the pressure rod 84 is detachable, it is convenient to replace or adjust the position of the pressure plate 85 relative to the pressure rod 84 to accommodate samples of different sizes or shapes.

[0025] In some embodiments, the connecting rod 83 has a threaded hole extending vertically, and the outer peripheral wall of the pressure rod 84 is provided with an external thread. The pressure rod 84 is threadedly connected to the threaded hole, and a nut 86 is also threadedly connected to the pressure rod 84. The nut 86 is used to fix the pressure rod 84 to the connecting rod 83. When it is necessary to change the height of the pressure rod 84 relative to the connecting rod 83, the pressure rod 84 is turned to a suitable position, and then the nut 86 is used to lock the pressure rod 84 to the connecting rod 83, thereby improving the versatility of the grinding equipment.

[0026] In some embodiments, a buffer plate (not shown) is provided on the lower surface of the pressure plate 85. The buffer plate reduces the rigid contact between the rigid pressure plate 85 and the hard sample, thus preventing damage to the sample surface.

[0027] In some embodiments, the first moving mechanism 6 includes two first bearing seats 61 disposed front and rear on the upper surface of the frame 1, a first screw 62 rotatably disposed between the two first bearing seats 61, and a first nut seat 63 disposed on the lower surface of the slide 3 and threadedly connected to the first screw 62; one end of the first screw 62 passes through one of the first bearing seats 61 and is connected to a first handwheel 64. In use, rotating the first handwheel 64 clockwise or counterclockwise causes the first screw 62 to rotate, thereby causing the first nut seat 63 to move forward or backward, thus moving the slide 3 forward or backward.

[0028] In some embodiments, the upper surface of the frame 1 is further provided with two first guide rails 11, the first screw 62 is located between the two first guide rails 11, and the lower surface of the carriage 3 is provided with a first slider 12 corresponding to the first guide rail 11, the first slider 12 being slidably disposed on the corresponding first guide rail 11. The first guide rails 11 and the first slider 12 are provided to improve the stability of the carriage 3 when moving back and forth.

[0029] In some embodiments, limit blocks 13 are provided at the ends of both first guide rails 11. The provision of limit blocks 13 ensures that the first slider 12 can only reciprocate between the two limit blocks 13, thus limiting the travel of the carriage 3.

[0030] In some embodiments, the second moving mechanism 7 includes a second nut seat 71 disposed on the upper surface of the lifting frame 4, and a second screw 72 threadedly connected to the second nut seat 71 and extending vertically; the slide 3 includes a base plate 31 and an n-shaped bracket 32 ​​fixedly connected to the upper surface of the base plate 31, the upper end of the second screw 72 passing through the upper part of the n-shaped bracket 32 ​​and connected to a second handwheel 73. Similarly, by rotating the second handwheel 73, the second screw 72 is rotated, which can drive the lifting frame 4 to rise or fall, thereby changing the position of the grinding head 52 relative to the sample in the vertical direction.

[0031] In some embodiments, the two inner sidewalls of the n-shaped bracket 32 ​​are respectively provided with vertically extending second guide rails 33, and the second screw 72 is located between the two second guide rails 33. The two outer sidewalls of the lifting frame 4 are respectively provided with second sliders 34 corresponding to the second guide rails 33, and the second sliders 34 are slidably disposed on the corresponding second guide rails 33. The second guide rails 33 and the second sliders 34 are provided to improve the smoothness of the lifting frame 4 when it rises or falls.

[0032] In some implementations, the first handwheel 64 and the second handwheel 73 can be replaced with motors to improve the automation level of the grinding equipment.

[0033] In some embodiments, the lower surface of the worktable 2 is provided with an adjusting plate 21. The adjusting plate 21 has a plurality of oblong holes 22 parallel to the moving direction of the slide 3. The frame 1 is provided with mounting holes of the same number as the oblong holes 22. Screws (not shown in the figure) are installed in the mounting holes and the corresponding oblong holes 22. When it is necessary to make a fine adjustment to the position of the worktable 2 relative to the frame 1 in the front-back direction, the screws can be loosened, the adjusting plate 21 can be moved, and then the screws can be tightened.
