DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Reference Figure 1-3 A small vertical grinder tool adjustment device comprises: a base plate 1, four groups of support columns 4 are fixedly installed on the top of the base plate 1, a top frame 5 is fixedly installed on the top of the four groups of support columns 4, a worm 7 and a rotating rod 9 are rotatably installed inside the top frame 5, a turntable 6 is rotatably installed on one side of the top frame 5, the turntable 6 is fixedly installed on one end of the worm 7, a worm gear 8 and a bevel gear 10 are fixedly installed on the outside of the rotating rod 9, a screw 12 is rotatably installed on the bottom of the top frame 5, a bevel gear 2 11 is fixedly installed on the top of the screw 12, a threaded sleeve 13 is threadedly connected to the outside of the screw 12, a movable plate 14 is fixedly installed on the bottom of the threaded sleeve 13, two groups of limit rods 15 are slidably installed inside the movable plate 14, a motor 16 is fixedly installed on the bottom of the movable plate 14, and a grinding tool 17 is fixedly installed on the output end of the motor 16.

[0020] In this embodiment, a bottom frame 2 is fixedly installed on the top of the bottom plate 1, and a bidirectional screw rod 18 is rotatably installed inside the bottom frame 2. The outer side of the bidirectional screw rod 18 is threadedly connected to two groups of moving blocks 19. The two groups of moving blocks 19 are slidably installed on the top of the two groups of moving blocks 19. A connecting block 21 is fixedly installed on the top of each of the two groups of connecting blocks 21, and a clamp 22 is fixedly installed on one side of each of the two groups of connecting blocks 21. This precise adjustment capability is very important for clamping workpieces of different sizes, which can ensure that the workpiece is firmly clamped in the appropriate position and provide a stable foundation for the processing of the grinding tool 17.

[0021] In this embodiment, the worm 7 is meshed with the worm wheel 8, and the bevel gear 1 10 is meshed with the bevel gear 2 11. Four sets of support legs 3 are fixedly installed on the bottom of the base plate 1, and the bottoms of the four sets of support legs 3 are fixedly installed with anti-slip pads, that is, only the worm 7 can drive the worm wheel 8 to rotate, and the worm wheel 8 cannot drive the worm 7 to rotate. This feature can ensure that after the height of the grinding tool 17 is adjusted, the device can remain stable and will not cause unexpected height changes due to external forces or vibrations during the operation of the grinder, thereby ensuring processing accuracy.

[0022] In this embodiment, two sets of sliding holes are opened inside the movable plate 14, and two sets of limiting rods 15 are slidably installed in the corresponding sliding holes. The sliding holes provide a clear movement path for the limiting rods 15, so that the movable plate 14 can only move up and down along the direction of the limiting rods 15. This precise guiding effect ensures that the movable plate 14 will not deviate or shake during the movement, thereby ensuring the accuracy and stability of the adjustment of the mold 17.

[0023] In this embodiment, a motor 20 is fixedly mounted on one side of the bottom frame 2, and one end of the bidirectional screw 18 is fixedly mounted on the output end of the motor 20. This is crucial for the adjustment device of the grinding tool 17 of the grinding machine, because it can ensure that the clamping force and position accuracy of the clamp 22 for workpieces of different sizes reach the optimal state. For example, when processing small precision parts, the motor 20 can achieve tiny movement adjustments to meet the requirements of high-precision processing.

[0024] In this embodiment, two groups of guide grooves 23 are provided on the top of the bottom frame 2, and the two sides of the two groups of moving blocks 19 are slidably installed in the corresponding guide grooves 23. One side of the two groups of clamps 22 is provided with anti-slip grooves. The guide grooves 23 on the top of the bottom frame 2 provide a clear path for the movement of the moving block 19, so that it can only move linearly in a specific direction. This is crucial for the precise operation of the adjustment device of the mold 17, because it ensures that the moving block 19 will not be offset or skewed when adjusting its position, thereby ensuring that the clamping position of the clamp 22 on the workpiece is accurate.

[0025] In this embodiment, when in use, by placing the workpiece to be polished on the bottom frame 2, starting the second motor 20 to drive the bidirectional screw 18 to rotate, thereby driving the moving block 19 to move relatively under the restriction of the guide groove 23, and then driving the connecting block 21 to move relatively, thereby driving the clamp 22 to clamp and fix the workpiece to be polished. The position of the moving block 19 can be adjusted according to the workpieces of different sizes, thereby changing the clamping range of the clamp 22, and can adapt to various sizes of workpieces to be polished, thereby improving the versatility and applicability of the grinder; starting the first motor 16 to drive the grinding tool 17 to pre-start The worm gear 7 is rotated in the top frame 5, and the worm gear 8 is driven to drive the rotating rod 9 to rotate, thereby driving the bevel gear 10 to rotate, and the bevel gear 10 is meshed with the bevel gear 2 11, thereby driving the bevel gear 2 11 to drive the screw 12 to rotate, and the screw 12 is threadedly connected to the threaded sleeve 13, thereby driving the threaded sleeve 13 to move up and down, and then driving the movable plate 14 to move up and down horizontally under the restriction of the limit rod 15, thereby driving the motor 16 and the grinding tool 17 to move up and down to the specified position to grind the workpiece to be ground.
