CONTENT OF UTILITY MODEL

[0005] In order to overcome the numerical control processing machine tool's grinding device when using, the clamp on its work surface cannot be turned over, leading to after grinding the top of workpiece, cannot directly turn over workpiece through clamp, needs to cooperate with special overturning device and turns over, improves production cost and is more time-consuming Problem.

After the two clamping plates clamp the workpiece, the rotation of the left clamping plate can drive the workpiece, the right clamping plate and the rotating rod to rotate, thereby realizing the flipping of the workpiece. This solves the problem that the fixtures on the working surface of the existing CNC machining grinding device cannot be flipped when in use, which means that after grinding the top of the workpiece, it is not possible to directly flip the workpiece with the fixtures. It is necessary to use a special flipping device to flip it, which increases the production cost and is more time-consuming.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting a first drive motor, its output end will drive the drive gear to rotate during operation. When the drive gear rotates, it will drive the driven gear meshing with it to rotate synchronously. When the driven gear rotates, it can drive the electric push rod and the inner ring of the first bearing to rotate, thereby driving the clamping plate to rotate. After the two clamping plates clamp the workpiece, the rotation of the left clamping plate can drive the workpiece, the right clamping plate and the rotating rod to rotate, thereby realizing the flipping of the workpiece. This solves the problem that the fixtures on the working surface of the existing CNC machining grinding device cannot be flipped when in use, which makes it impossible to directly flip the workpiece after grinding the top of the workpiece.

[0022] Please see Figures 1-4This utility model provides an embodiment of a grinding device for a CNC machine tool, including a lathe table 1; it also includes a first bearing 4, a driven gear 5, a first drive motor 6, a drive gear 7, and a rotary rod 8. A grinding module 2 is arranged on the rear side of the upper surface of the lathe table 1. An electric push rod 3 is inserted into the left side surface of the lathe table 1. A first bearing 4 is arranged on the left side of the outer surface of the electric push rod 3. The electric push rod 3 is rotatably connected to the lathe table 1 through the first bearing 4. A driven gear 5 is arranged on the left side surface of the electric push rod 3. A first drive motor 6 is arranged on the left side of the bottom surface of the lathe table 1. A drive gear 7 is arranged at the output end of the first drive motor 6. The drive gear 7 and the driven gear 8 are connected to the driven gear 5. The drive gear 5 is engaged, and a rotating rod 8 is inserted and rotatably connected to the right side surface of the lathe table 1. Both the telescopic end of the electric push rod 3 and the end of the rotating rod 8 near the electric push rod 3 are equipped with clamping plates 9. By setting the first drive motor 6, its output end will drive the drive gear 7 to rotate during operation. When the drive gear 7 rotates, it will drive the driven gear 5, which meshes with it, to rotate synchronously. When the driven gear 5 rotates, it can drive the electric push rod 3 and the inner ring of the first bearing 4 to rotate, thereby driving the clamping plates 9 to rotate. After the two clamping plates 9 clamp the workpiece, the rotation of the left clamping plate 9 can drive the workpiece, the right clamping plate 9 and the rotating rod 8 to rotate, thereby realizing the flipping of the workpiece.

[0023] Please see Figures 1-3 In this embodiment, two symmetrical second bearings 10 are provided on the outer surface of the rotating rod 8. The rotating rod 8 is rotatably connected to the lathe table 1 through the second bearings 10. By providing the second bearings 10, the rotating rod 8 can rotate inside the lathe table 1, improving the stability of the rotating rod 8. An equipment box 11 is provided on the right side surface of the lathe table 1 below the rotating rod 8. A second drive motor 12 is provided on the rear surface of the equipment box 11. The output end of the second drive motor 12 passes through the rear surface of the equipment box 11 and is connected to one end of a bidirectional screw 13. The other end of the bidirectional screw 13 is rotatably connected to the front side of the inner surface of the equipment box 11. Two symmetrical movable seats 14 are threadedly connected to the outer surface of the screw 13. By setting a second drive motor 12, its output end will drive the bidirectional screw 13 to rotate during operation. When the bidirectional screw 13 rotates, it will drive the two movable seats 14 that are threaded with it to move synchronously in opposite directions. One end of the connecting rod 15 is provided on the top surface of the movable seat 14, and the other end of the connecting rod 15 is provided with a clamping block 16. By setting the clamping block 16, when the movable seat 14 moves, it can drive the connecting rod 15 and the clamping block 16 to move synchronously, so that the two clamping blocks 16 clamp the rotating rod 8 and prevent the rotating rod 8 from rotating during processing.

[0024] Please see Figures 1-4In this embodiment, a recycling bin 17 is provided at the bottom of the lathe table 1. A filter screen 18 is inserted into the upper part of the front surface of the recycling bin 17. By setting up the recycling bin 17 and the filter screen 18, the grinding fluid and debris sprayed during processing will fall into the recycling bin 17. The filter screen 18 can separate the debris for easy recycling. Slider 19 is provided on both the left and right sides of the filter screen 18. The filter screen 18 is slidably connected to the recycling bin 17 through the slider 19. A pull rod 20 is provided on the front surface of the filter screen 18. By setting up the slider 19 and the pull rod 20, the operator can easily pull the pull rod 20 to remove the filter screen 18 from the inside of the recycling bin 17 for cleaning. Universal wheels 21 are provided at the corners of the bottom surface of the recycling bin 17. The universal wheels 21 are fixed to the recycling bin 17 by screws. By setting up the universal wheels 21, the recycling bin 17 can be moved easily, improving the convenience of use.

[0025] During operation, the second bearing 10 enables the rotating rod 8 to rotate inside the lathe table 1, improving the stability of the rotating rod 8's rotation. The second drive motor 12, during operation, drives the bidirectional screw 13 to rotate. The bidirectional screw 13, when rotating, drives the two threaded moving seats 14 to move synchronously in opposite directions. The clamping blocks 16, when the moving seats 14 move, drive the connecting rod 15 to move synchronously with the clamping blocks 16, thus allowing the two clamping blocks 16 to hold the rotating rod 8... The device is clamped to prevent the rotating rod 8 from rotating during processing. By setting up a recycling bin 17 and a filter screen 18, the grinding fluid and debris sprayed during processing will fall into the recycling bin 17. The filter screen 18 can separate the debris for easy recycling. By setting up a slider 19 and a pull rod 20, the operator can easily pull the pull rod 20 to remove the filter screen 18 from the inside of the recycling bin 17 for cleaning. By setting up casters 21, the recycling bin 17 can be moved easily, improving the convenience of use.

[0026] Through the above steps, by setting the first drive motor 6, its output end will drive the drive gear 7 to rotate during operation. When the drive gear 7 rotates, it will drive the driven gear 5 meshing with it to rotate synchronously. When the driven gear 5 rotates, it can drive the electric push rod 3 and the inner ring of the first bearing 4 to rotate, thereby driving the clamping plate 9 to rotate. After the two clamping plates 9 clamp the workpiece, the rotation of the left clamping plate 9 can drive the workpiece, the right clamping plate 9 and the rotating rod 8 to rotate, thereby realizing the flipping of the workpiece. This solves the problem that the fixtures on the working surface of the existing CNC machining machine tool grinding device cannot be flipped when in use, which makes it impossible to directly flip the workpiece after grinding the top of the workpiece. It requires the use of a special flipping device to flip it, which increases the production cost and is more time-consuming.
