[0045] When it is necessary to grind the surface of a hardware workpiece, firstly, the hardware workpiece is clamped at the front end of the clamping connecting rod 311 by the clamping claw 312, and then the motor 13 is started to drive the screw rod 15 to rotate. Since the outer wall of the output end of the motor 13 is fixedly connected to the transmission shaft 14, the transmission shaft 14 is connected to the outer wall of the second transmission shaft 18 by the crawler 16. When the transmission screw rod 15 of the motor 13 rotates, the crawler 16 drives the second screw rod 17 and the screw rod 15 to rotate at the same time, thereby rotating the transmission plate bottom plate 21 to one side to the rear side where one of the grinding mechanisms 5 is needed. , and then start the slide rod rotation motor 19. After the slide rod rotation motor 19 is started, the transmission slide rod 110 rotates, thereby driving the worm connecting groove 25 to rotate, so that the meshing gear 28 drives the third screw rod 24 to rotate the inner wall of the transmission top plate groove 23 opened at the top of the transmission top plate 22, so that the transmission block 32 of the transmission clamping mechanism drives the clamping mechanism bottom plate 31 to move axially at the top of the transmission top plate 22 through the third screw rod 24 to the inner wall of the selected grinding mechanism 5. At this time, the hardware workpiece has been accurately located at the grinding position in the grinding mechanism, ready for grinding operation.

[0046] like Figure 5-10As shown, the grinding mechanism 5 includes a grinding mechanism connecting plate 51, the outer wall of the grinding mechanism connecting plate 51 is slidably connected with a circular baffle 52, the front side of the grinding mechanism connecting plate 51 is rotatably connected with a grinding chamber 53, the inner side of the grinding chamber 53 is rotatably connected with a plurality of grinding rods 54, the grinding mechanism connecting plate 51 includes a grinding mechanism connecting plate body 511, the bottom of the grinding mechanism connecting plate body 511 is fixedly connected with a bottom connecting block 512, the front top of the grinding mechanism connecting plate body 511 is fixedly connected with a second motor 513, the output end of the second motor 513 is fixedly connected with a fourth screw rod 514, and the grinding chamber 53 is rotatably connected with a plurality of grinding rods 54. The grinding chamber rotating shaft 531 includes a grinding chamber rotating shaft 531, the outer wall of which is slidably connected to the inner wall of the grinding mechanism connecting plate body 511, the front side of the grinding chamber rotating shaft 531 extends to the front side outer wall of the grinding mechanism connecting plate body 511 and is fixedly connected to the grinding chamber rotating disk 532, the outer wall top of the grinding chamber rotating disk 532 is fixedly connected to a rotating block 533, the front side of the rotating block 533 is fixedly connected to a rotating transmission block 534, the inner wall of the rotating transmission block 534 is threadedly connected to the outer wall of the fourth screw rod 514, and the front side annular array of the grinding chamber rotating disk 532 is respectively fixedly connected to a plurality of front rotating disk connecting rods 535, and the plurality of front rotating disk connecting rods 535 are fixedly connected to the front side annular array of the grinding chamber rotating disk 532. The front side of the connecting rod 535 is fixedly connected to the front turntable 536, and the plurality of grinding rods 54 include grinding rod connecting rods 541. The rear ends of the plurality of grinding rod connecting rods 541 are respectively fixedly connected to the front side of the grinding mechanism connecting disk body 511 in an annular array. The outer walls of the plurality of grinding rod connecting rods 541 are rotatably connected to rotating rods 543. The outer walls of the plurality of rotating rods 543 are fixedly connected to grinding rod connecting shells 542. The outer walls of the plurality of grinding rod connecting shells 542 are respectively rotatably connected to the opposite sides of the front turntable 536 and the grinding chamber turntable 532 in an annular array. The plurality of rotating rods 543 are respectively connected to the opposite sides of the front turntable 536 and the grinding chamber turntable 532 in an annular array. A grinding wheel 544 is fixedly connected, the internal structures of the multiple grinding mechanisms 5 are the same, the outer walls of the grinding wheels 544 fixed to the inner walls of the multiple grinding mechanisms 5 have different patterns, the circular baffle 52 includes a circular baffle body 521, the rear side annular array inside the circular baffle body 521 is respectively fixedly connected with spring connecting blocks 522, the front sides of the multiple spring connecting blocks 522 are all fixedly connected with springs 523, the front ends of the multiple springs 523 are respectively fixedly connected to the rear side of the grinding mechanism connecting plate body 511 in an annular array, and the front side of the inner side of the circular baffle body 521 is slidably connected to the outer wall of the grinding mechanism connecting plate body 511;

[0047] When the clamping mechanism transmission block 32 drives the clamping mechanism bottom plate 31 to move toward the grinding mechanism connecting plate 51, the push plate 310 pushes the circular baffle body 521 to slide forward, compressing the spring 523, so that a slight elastic contact is generated between the spring connecting block 522 and the grinding mechanism connecting plate body 511. This design not only ensures that the clamping mechanism can stably contact the grinding mechanism when it moves to the specified position, but also effectively reduces the vibration and noise that may be generated by direct collision through the buffering effect of the spring, thereby improving the stability and service life of the equipment. As the clamping mechanism bottom plate 31 continues to move, the push plate 310 eventually covers the outer wall of the grinding bin 53 with the circular baffle body 521, and at the same time, the hardware workpiece clamped by the clamping claw 312 extends into the inner wall of the grinding bin 53.

[0048] Then, the second motor 513 is started to drive the fourth screw rod 514 to rotate. After the fourth screw rod 514 rotates, it drives the rotating transmission block 534 to move axially on the outer wall of the rotating transmission block 534 and drives the rotating block 533 to move, thereby rotating the grinding chamber turntable 532. When the grinding chamber turntable 532 rotates, it drives the multiple front turntable connecting rods 535 and the front turntable 536 to rotate together, thereby causing the multiple grinding rod connecting shells 542 fixed on the front turntable 536 to rotate accordingly. This series of rotational actions drives the rotating rod 543 installed on the inner wall of the grinding rod connecting shell 542 and the grinding wheel 544 thereon to perform circular motion, so that the multiple grinding wheels 544 are attached to the surface of the hardware workpiece in a circular array;

[0049] Then, the servo motor 33 is started. Under the precise control of the servo motor 33, the turntable 34 starts to rotate at a constant speed. This action directly drives the clamping mechanism bottom plate 31 and the hardware workpiece clamped thereon to rotate. As the hardware workpiece rotates stably in the grinding chamber 53, the contact with the grinding wheel 544 becomes more uniform and sufficient, ensuring the comprehensiveness and efficiency of the grinding process.

[0050] At the same time, since the outer wall textures of the grinding wheels 544 fixed inside the multiple grinding mechanisms 5 are different, these different texture designs provide a variety of grinding effects and options for the surfaces of hardware workpieces of different materials, shapes and roughness. As the rotation of the workpiece and the rotation of the grinding wheel are superimposed on each other, the surface of the workpiece gradually becomes smooth and delicate, achieving the expected grinding quality;

[0051] During the grinding process, the circular baffle 52 not only guides the clamping mechanism to accurately enter the grinding chamber, but also effectively prevents the debris and dust generated during grinding from splashing into the equipment or the surrounding environment, thereby maintaining the cleanliness and safety of the working area.

[0052] In addition, since the rotation speed and rotation direction of the servo motor 33 can be adjusted, the rotation speed can be adjusted as needed to achieve multi-stage grinding.

[0053] In addition, the present invention also relates to a hardware workpiece surface graded grinding device and a process thereof, comprising the following steps:

[0054] Step 1: Start the equipment and set the required grinding parameters through the control system, including grinding time, servo motor speed, grinding wheel selection, etc., to ensure that the equipment works according to the preset process requirements;

[0055] Step 2: Place the hardware workpiece to be polished on the clamping jaws 312 of the clamping mechanism, and firmly clamp the workpiece by closing the clamping jaws to ensure that the workpiece will not fall off or shift due to vibration or external force during the polishing process;

[0056] Step 3: The clamping mechanism is driven by the transmission mechanism to move toward the grinding mechanism connecting plate 51, and at the same time, the push plate 310 contacts the circular baffle body 521 and pushes it to slide forward, compressing the spring 523 to achieve a smooth docking process. At this time, the hardware workpiece clamped by the clamp has accurately extended into the grinding chamber 53;

[0057] Step 4: Start the second motor 513, and drive the rotation transmission block 534 and the grinding chamber turntable 532 to rotate through the rotation of the fourth screw rod 514, thereby driving the front turntable 536 and the grinding rod connecting shell 542 to rotate, so that the grinding wheel 544 fits the surface of the workpiece;

[0058] Step 5: During grinding, the servo motor 33 is started, and the driving turntable 34 drives the clamping mechanism bottom plate 31 and the workpiece to rotate, forming a composite motion with the rotation of the grinding wheel to achieve a finer and more uniform grinding effect. At the same time, the speed of the servo motor can be adjusted as needed to meet the needs of different grinding stages;

[0059] Step 6: When the preset grinding time is reached or it is observed that the surface of the workpiece has achieved the expected grinding effect, the servo motor is stopped, the clamping mechanism returns to its original position under the drive of the transmission mechanism, and the polished hardware workpiece is taken out.

[0060] Working principle of the present invention: when it is necessary to grind the surface of a hardware workpiece, firstly, the hardware workpiece is clamped at the front end of the clamping connecting rod 311 by the clamping claw 312, and then the motor 13 is started to drive the screw rod 15 to rotate. Since the outer wall of the output end of the motor 13 is fixedly connected to the transmission shaft 14, the transmission shaft 14 is connected to the outer wall of the second transmission shaft 18 by the crawler 16. When the transmission screw rod 15 of the motor 13 rotates, the crawler 16 drives the second screw rod 17 and the screw rod 15 to rotate at the same time, thereby rotating the transmission plate bottom plate 21 to move to one side until one of the grinding mechanisms is required. 5, and then the slide rod rotating motor 19 is started. After the slide rod rotating motor 19 is started, the transmission slide rod 110 rotates, thereby driving the worm connecting groove 25 to rotate, so that the meshing gear 28 drives the third screw rod 24 to rotate the inner wall of the transmission top plate slot 23 opened at the top of the transmission top plate 22, so that the transmission block 32 of the transmission clamping mechanism drives the clamping mechanism bottom plate 31 to move axially at the top of the transmission top plate 22 through the third screw rod 24 to the inner wall of the selected grinding mechanism 5. At this time, the hardware workpiece has been accurately located at the grinding position in the grinding mechanism, ready for grinding operation;

[0061] When the clamping mechanism transmission block 32 drives the clamping mechanism bottom plate 31 to move toward the grinding mechanism connecting plate 51, the push plate 310 pushes the circular baffle body 521 to slide forward, compressing the spring 523, so that a slight elastic contact is generated between the spring connecting block 522 and the grinding mechanism connecting plate body 511. This design not only ensures that the clamping mechanism can smoothly contact the grinding mechanism when it moves to the specified position, but also effectively reduces the vibration and noise that may be generated by direct collision through the buffering effect of the spring, thereby improving the stability and service life of the equipment. As the clamping mechanism bottom plate 31 continues to move, the push plate 31 Finally, the outer wall of the grinding chamber 53 is covered with the circular baffle body 521, and the hardware workpiece clamped by the clamping claw 312 extends into the inner wall of the grinding chamber 53. Then, the second motor 513 is started to drive the fourth screw rod 514 to rotate. After the fourth screw rod 514 rotates, the rotating transmission block 534 moves axially on the outer wall of the rotating transmission block 534 and drives the rotating block 533 to move, thereby rotating the grinding chamber turntable 532. When the grinding chamber turntable 532 rotates, it drives the multiple front turntable connecting rods 535 and the front turntable 536 to rotate together, thereby causing the multiple grinding rod connecting shells 542 fixed on the front turntable 536 to rotate accordingly. The series of rotational actions drive the rotating rod 543 installed on the inner wall of the grinding rod connecting shell 542 and the grinding wheel 544 thereon to perform circular motion, so that the multiple grinding wheels 544 are attached to the surface of the hardware workpiece in a circular array, and then the servo motor 33 is started. Under the precise control of the servo motor 33, the turntable 34 begins to rotate at a constant speed. This action directly drives the clamping mechanism bottom plate 31 and the hardware workpiece clamped thereon to perform rotational motion. As the hardware workpiece rotates stably in the grinding chamber 53, the contact with the grinding wheel 544 becomes more uniform and sufficient, ensuring the comprehensiveness and efficiency of the grinding process. At the same time, since the outer wall patterns of the grinding wheels 544 fixed inside the multiple grinding mechanisms 5 are different, these different pattern designs provide a variety of grinding effects and options for the surfaces of hardware workpieces of different materials, shapes and roughness. As the rotation of the workpiece and the rotation of the grinding wheel are superimposed on each other, the surface of the workpiece gradually becomes smooth and delicate, achieving the expected grinding quality. During the grinding process, the circular baffle 52 not only guides the clamping mechanism to accurately enter the grinding chamber, but also effectively prevents the debris and dust generated during grinding from splashing into the equipment or the surrounding environment, thereby maintaining the cleanliness and safety of the working area.
