Detailed implementation

[0022] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] Refer to Figures 1-5 , a metal tool grinding device, including a base 1 and a workpiece 2, and a controller 30 is installed on the front surface of the base 1.

[0024] A first chute 4 is provided on one side of the upper surface of the base 1, and a first mounting plate 3 is fixedly connected to the other side of the upper surface of the base 1. A second mounting plate 5 is slidably connected inside the first chute 4. A rotating shaft 6 is rotatably installed on the opposite surface of the second mounting plate 5 and the first mounting plate 3. And a stepping motor 14 for driving the rotating shaft 6 is fixedly installed on the side of the second mounting plate 5 away from the rotating shaft 6.

[0025] Refer to Figures 1-4 , clamping plates 7 are fixedly connected to the opposite ends of the two rotating shafts 6. A first clamping block 8 is fixedly connected to the lower surface of one side of the clamping plate 7. And a second chute 9 is provided in the middle of one side of the clamping plate 7. A second clamping block 10 is slidably installed inside the second chute 9. Grooves 11 corresponding to the workpiece 2 are provided inside the second clamping block 10 and the first clamping block 8. During use, the stepping motor 14 rotates a step distance to drive the workpiece 2 to rotate a step distance, eliminating the need for the operator to manually remove and turn the workpiece over for fixing and grinding, facilitating the grinding of different surfaces of the workpiece 2.

[0026] Refer to Figure 3 , a plurality of vertically arranged limiting holes 12 are provided on the front surface of the clamping plate 7. A limiting screw 13 is threadedly connected inside the limiting holes 12. After the limiting screw 13 rotates to the bottom of the bottom limiting hole 12, it abuts against the second clamping block 10 for limiting, preventing the second clamping block 10 from sliding inside the second chute 9 during operation. By limiting the height of the second clamping block 10 through different limiting holes 12, it is convenient to use with workpieces 2 of different models.

[0027] Refer to Figure 1, on one side of the base 1, there is a threaded rod 15 which passes through the inside of the first chute 4 and is in threaded fit with the base 1. One end of the threaded rod 15 is rotatably connected to the surface of the second mounting plate 5, and the other end of the threaded rod 15 is fixedly installed with a knob 16. By turning the knob 16, the threaded rod 15 rotates, thereby driving the second mounting plate 5 to slide inside the first chute 4 and adjusting the distance from the first mounting plate 3, so as to facilitate the grinding of workpieces 2 with different lengths.

[0028] Reference Figure 2 and Figure 5 , on the upper surface of the base 1, four columns 17 are fixedly connected. The top of the columns 17 is fixedly connected with a top plate 18. On the top of the top plate 18, a cylinder 19 is fixedly installed. The output end of the cylinder 19 is fixedly connected with a support plate 20 which is penetrated by the columns 17. When the cylinder 19 pushes the support plate 20 to move downward to grind the workpiece 2, the columns 17 ensure the stability during its operation.

[0029] Reference Figure 5 , on both sides of the lower surface of the support plate 20, side plates 21 are fixedly installed. A lead screw 23 is rotatably installed between the two side plates 21, and a servo motor 22 for driving the lead screw 23 is fixedly installed on one side of one of the side plates 21. A limit groove 24 is provided on the lower surface of the support plate 20. A slider 25 which slides in the limit groove 24 is threadedly installed on the surface of the lead screw 23. A grinding motor 26 is fixedly installed on the lower surface of the slider 25. The output end of the grinding motor 26 is fixedly installed with a grinding wheel 27. The grinding wheel 27 is a wire wheel, which is convenient for grinding the corners of the workpiece 2.

[0030] Reference Figure 2 , on the front and rear sides of the workpiece 2, a dust collector 28 fixedly installed on the base 1 is provided. A square dust suction hood 29 is provided on the top of the dust collector 28, which is convenient for use with the workpiece 2. When the workpiece 2 is being ground, the dust collector 28 sucks in the grinding debris to protect the surrounding working environment.

[0031] Furthermore, insert the lower end of the workpiece 2 into the groove 11 of the first clamping block 8, adjust the second clamping block 10 so that the upper end of the workpiece 2 corresponds to the groove 11 of the second clamping block 10. Rotate the knob 16 to make the threaded rod 15 rotate and drive the second mounting plate 5 to move, so that the groove 11 on the second mounting plate 5 clamps the workpiece 2 for fixation. Control the cylinder 19 to push the support plate 20 to move downward so that the grinding wheel 27 is located on the upper surface of the workpiece 2. Make the servo motor 22 rotate, so that the lead screw 23 rotates, and then the slider 25 drives the grinding wheel 27 to move left and right to grind the workpiece 2 from left to right. When one side is ground, the stepping motor 14 rotates, thereby driving the workpiece 2 to rotate by a step distance for turning over, and the different surfaces of the workpiece 2 can be ground. During the grinding process, the dust collector 28 absorbs the grinding debris through the dust suction hood 29.

Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in names as a way to distinguish components, but rather use the difference in functions of components as the criterion for distinction.
