[0021] In this embodiment, the X-axis moving assembly 15, Y-axis moving assembly 14, and Z-axis moving assembly 13 have the same structure. The X-axis moving assembly 15 includes a moving box with an opening on one side. A moving screw is disposed inside the moving box, and a moving block is threaded onto the moving screw. The moving block is fixedly connected to the connecting arm 16. One end of the moving screw passes through the moving box and is connected to a servo motor.

The moving block in the Y-axis moving assembly 14 is connected to the bottom end of the moving box in the X-axis moving assembly 15. The moving box is fixedly connected. The servo motors in the X-axis moving assembly 15, Y-axis moving assembly 14 and Z-axis moving assembly 13 are all equipped with self-locking function. The servo motor drives the moving screw to rotate. The screw and the moving block are connected by threads to realize the movement of the milling cutter 19. The cooperation of the three moving assemblies can realize the flexible movement and positioning of the milling cutter 19 in the XYZ axis direction. At the same time, the X-axis moving assembly 15, Y-axis moving assembly 14 and Z-axis moving assembly 13 are all made of steel structure, and the structural strength is sufficient to support the flexible movement of the milling cutter 19.

[0022] In this embodiment, an L-shaped notch is provided on the front side of the workbench 1, and several docking holes 101 are provided at the notch. The movable plate 2 has an L-shaped structure corresponding to the notch. The movable plate 2 is provided with docking posts 201 that are inserted and matched with the docking holes 101. A latch 12 is provided between the movable plate 2 and the workbench 1. The bottom of the workbench 1 has at least four support legs, and the bottom of the movable plate 2 has at least one support leg. This arrangement can make the device more stable as a whole. The latch 12 is a general safety latch lock structure. The movable plate 2 can be installed and fixed through the latch 12.

[0023] In this embodiment, the adjusting part 3 includes a first adjusting plate 301 fixedly connected to the piston end of the third hydraulic cylinder 11. A second adjusting plate 303 and a support plate 304 are sequentially arranged above the first adjusting plate 301 from bottom to top. A first adjusting groove 307 is formed on the upper surface of the first adjusting plate 301 along the extension direction of the X-axis moving assembly 15. A first adjusting block 302 extending into the first adjusting groove 307 is provided on the lower surface of the second adjusting plate 303. A first adjusting assembly 4 for driving the first adjusting block 302 to move is provided in the first adjusting groove 307. The upper surface of the second adjusting plate 303 extends along the extension direction of the Z-axis moving assembly 13. A second adjustment groove 308 is provided in the first adjustment plate 301. A second adjustment block 305 extending into the second adjustment groove 308 is provided on the lower surface of the support plate 304. A second adjustment component 5 for driving the second adjustment block 305 to move is provided in the second adjustment groove 308. Four directional wheels 306 are provided below the first adjustment plate 301. A ventilation groove 3041 is provided inside the support plate 304. The first adjustment component 4 has the same structure as the second adjustment component 5. The first adjustment component 4 includes a first adjustment screw 401 horizontally arranged in the first adjustment groove 307. The first adjustment screw 401 passes through the first adjustment block 302. The adjusting block 302 is threadedly engaged with the first adjusting screw 401. One end of the first adjusting screw 401 extends through the first adjusting plate 301 and is provided with an adjusting disc 402 at its end. The side of the first adjusting plate 301 has several positioning holes arranged in a ring around the first adjusting screw 401. The adjusting disc 402 is provided with positioning pins 403 that correspond to the positioning holes. In actual use, the workpiece is first fixed on the adjusting part 3 by the clamping assembly 6. The adjusting disc 402 is rotated, and the adjusting disc 402 drives the first adjusting screw 401 to rotate. The first adjusting screw and the first adjusting block 302 are threadedly engaged. The first adjusting block 302 moves along the first adjusting groove 307, thereby causing the second adjusting plate 303 and the support plate 304 to move along the extension direction of the X-axis moving assembly 15. The second adjusting assembly 5 is adjusted in the above manner, causing the support plate 304 to move along the extension direction of the Z-axis moving assembly 13 until the workpiece is moved to a suitable position (this position is when the third hydraulic cylinder 11 moves the workpiece to below the milling cutter disc 19, and the weld seam on the workpiece is facing the milling cutter disc 19). The adjusting part 3 is fixed by the cooperation of the positioning pin 403 and the positioning hole, which facilitates the cleaning of weld seams of the same batch of workpieces.

[0024] In this embodiment, the clamping assembly 6 includes two support blocks 601 and a first hydraulic cylinder 603. The two support blocks 601 are of different heights, and two clamping plates 602 are symmetrically arranged on the inner side of the two support blocks 601. A connecting part 604 is movably installed on the outer side of the clamping plate 602 through a spring connector 8. One of the connecting parts 604 is fixedly connected to the top of the lower support block 601. The first hydraulic cylinder 603 is fixedly installed on the outer side of the higher support block 601, and the piston end of the first hydraulic cylinder 603 passes through the higher support block 601, and the end is fixedly connected to the other connecting part 604. In specific use, when the unloading assembly 10 pushes the workpiece between the two clamping plates 602, the first hydraulic cylinder 603 is activated. The first hydraulic cylinder 603 pushes the clamping plates 602 to move, and the two clamping plates 602 are used to clamp and fix the workpiece.

[0025] In a preferred embodiment, the spring connector 8 includes a connecting post fixedly connected to the clamping plate 602, and a connecting groove formed on the connecting portion 604. The inner wall of the connecting groove has a frustum-shaped groove, and the connecting post has a mounting groove. A frustum-shaped protrusion corresponding to the groove is mounted in the mounting groove by a spring, and the two ends of the spring are fixedly connected to the mounting groove and the protrusion, respectively. With this configuration, when the connecting post is inserted into the connecting groove, the connecting groove squeezes the protrusion and overcomes the elastic force of the spring, causing the protrusion to retract completely into the mounting groove. This allows the connecting post to smoothly enter the connecting groove. When the connecting post is fully inserted into the connecting groove, the protrusion aligns with the groove. The spring force pushes the protrusion into the groove, completing the fixation of the connecting post and the connecting groove, thus enabling the installation of the clamping plate 602. When it is necessary to replace different clamping plates 602, simply pull the clamping plate 602 outwards. The inclined surface of the groove presses against the inclined surface of the protrusion, thereby pressing the protrusion into the installation groove, allowing the connecting post to be smoothly pulled out of the connecting groove, facilitating the replacement of clamping plates 602 of different sizes.

[0026] In this embodiment, a positioning component 9 is provided on the front side of the clamping component 6. The positioning component 9 includes a support rod 901 fixedly connected to the movable plate 2. A positioning plate 902 is movably mounted on the top of the support rod 901 via a screw. The position of the positioning plate 902 can be adjusted by rotating the screw, so that when the unloading component 10 pushes the workpiece between the two clamping plates 602, the positioning plate 902 can be used to position the workpiece, which facilitates the subsequent clamping and fixing of the workpiece.

[0027] In this embodiment, the air blowing assembly 7 includes an air pump 701 installed on one side of the clamping assembly 6. The output end of the air pump 701 is connected to an air supply pipe 703 (there are two air supply pipes 703; the two ends of the air supply pipe 703 near the air pump 701 are connected to the output end of the air pump 701 and the mounting block 702 respectively; one end of the other air supply pipe 703 is connected to the mounting block 702, and the other end is connected to the ventilation groove 3041 inside the support plate 304. The ventilation groove 3041 is connected to the output end of the air pump 701 through a pipe. This arrangement prevents the other air supply pipe 703 from bypassing the clamping plate 602, thus preventing it from affecting the clamping and fixing of the workpiece). The end of the air supply pipe 703 is fixed to the clamping assembly 6 via the mounting block 702. The bottom of the mounting block 702 has a slot corresponding to the top of the clamping plate 602, and the mounting block 702 and the clamping plate 602 are fixedly connected by screws. An internal cavity is provided, and the end of the air supply pipe 703 is connected to the cavity. Multiple air blowing ports are provided at the bottom of the mounting block 702, located inside the clamping plate 602, and these air blowing ports are connected to the cavity. In actual use, the air pump 701 is started, and high-pressure gas is delivered to the cavity of the mounting block 702 through the air supply pipe 703 and blown out through the air blowing ports to blow air onto the weld seam of the workpiece, so that the dust removed by the grinding of the weld seam is quickly blown away, preventing the dust from adhering to the weld seam and affecting the grinding process. As a preferred embodiment, the air blowing component 7 can be replaced with an air suction component, changing the air pump 701 from blowing to suction, and a filter bag is provided at the output end of the air pump 701. This filter bag is made of the same material as the filter bag in a vacuum cleaner. With this configuration, the air pump 701 directs the air blowing port to the workpiece to draw air, thereby collecting the dust removed by the grinding of the weld seam, which can also prevent the dust from adhering to the weld seam and affecting the grinding process.

[0028] In this embodiment, the feeding assembly 10 includes a pusher box 1001 with openings on the top and one side. The pusher box 1001 is fixed to the workbench 1 by bolts. The top of the pusher box 1001 is connected to a storage box 1003 with an opening at the top. The bottom opening of the storage box 1003 is the same size as the top opening of the pusher box 1001. A second hydraulic cylinder 1002 is installed on the outside of the side of the pusher box 1001 opposite to the opening. The piston end of the second hydraulic cylinder 1002 extends through the pusher box 1001. Inside the material box 1001, an L-shaped push plate 1004 is fixedly connected to its end via a connecting block. The width of the push plate 1004 is smaller than the width of the workpiece. This arrangement ensures that when the L-shaped push plate 1004 pushes the workpiece between the two clamping plates 602, the clamping plates 602 will not be obstructed by the L-shaped push plate 1004 when clamping the workpiece. The height of the L-shaped push plate 1004 from the storage box 1003 is equal to the height of the workpiece. The push box 1001 and the storage box 1003 mentioned in this specification... The box 1003 comes in various sizes to accommodate workpieces of different sizes. Different sizes of pusher box 1001 and storage box 1003 can be replaced using bolts to accommodate workpieces of varying sizes. The pusher box 1001 has a connecting hole at its top, and the storage box 1003 has a connecting post at its bottom that engages with the connecting hole. This engagement between the connecting hole and the connecting post allows for easy assembly and disassembly of the storage box 1003. In a preferred embodiment, the workpiece in this application has a flat bottom and a welded top, and its width is the same as the internal width of the storage box 1003. This allows the workpieces to be stacked within the storage box 1003 and fall smoothly into the pusher box 1001 sequentially. The second hydraulic cylinder 1002 in the pusher box 1001 can then smoothly push the workpiece between the two clamping plates 602 via the L-shaped push plate 1004, facilitating clamping and fixing of the workpiece by the clamping plates 602.

[0029] In this embodiment, a movable connecting arm 16 is installed on the X-axis moving assembly 15. A drive motor 18 is installed at the bottom of the connecting arm 16, and a floating force control actuator 17 is provided on the connecting arm 16. By setting the floating force control actuator 17 to rely on power sources such as hydraulic, pneumatic or voice coil motors, combined with high-precision force sensors and closed-loop control algorithms, the milling cutter disk 19 is kept in an adaptive floating state during the root clearing process. It automatically compensates for the workpiece's dimensional deviation and surface shape and position error, and always outputs a preset constant contact force to avoid workpiece damage or insufficient processing caused by rigid contact.

[0030] In this embodiment, positioning blocks 20 are respectively provided on both sides of the adjustment part 3, and the positioning blocks 20 can be fixed in different positions by screws. By setting the positioning blocks 20, the adjustment part 3 can be limited and fixed, so that when the third hydraulic cylinder 11 drives the adjustment part 3 to move, it can move to the predetermined position accurately. For example, when the third hydraulic cylinder 11 extends, it can move the adjustment part 3 to the unloading position. When the third hydraulic cylinder 11 retracts, it can move the adjustment part 3 to the bottom of the milling cutter 19, so that the milling cutter 19 can perform root cleaning on the workpiece.

[0031] This device, through the feeding component 10, can sequentially feed workpieces of the same batch onto the clamping component 6, and automatically clamp and fix them through the clamping component 6. Then, the third hydraulic cylinder 11 sends the workpiece to the milling cutter head 19 for weld cleaning, realizing automatic workpiece feeding. This device, through the air blowing component 7, blows air onto the weld position of the workpiece, quickly blowing away the dust removed by grinding, preventing dust from adhering to the weld and affecting the grinding process, thereby greatly improving the weld cleaning efficiency. This device, through the setting of multiple movable plates 2, can change the applicable range of the device by changing different movable plates 2, so that it can perform weld cleaning operations on workpieces of different sizes.

[0032] In practical use, the device is first debugged. According to the size of the workpiece, a suitable unloading component 10 is selected and replaced with bolts. Workpieces of the same batch are placed in the discharge box in the order of weld seam facing upwards. The workpieces fall from the storage box 1003 into the push box 1001 in sequence. The second hydraulic cylinder 1002 is activated. The second hydraulic cylinder 1002 pushes the workpiece between the two clamping plates 602 through the push plate 1004. The first hydraulic cylinder 603 is activated. The first hydraulic cylinder 603 pushes the clamping plate 602 to clamp and fix the workpiece. The third hydraulic cylinder 11 is activated. The third hydraulic cylinder 11 drives the workpiece to move through the adjustment part 3 and the clamping component 6, moving the workpiece to below the milling cutter disc 19. The X-axis moving component 15, Y-axis moving component 14 and Z-axis moving component 13 are used to control the milling cutter disc 19 to perform root cleaning treatment on the weld seam of the workpiece.

[0033] Example 2 Please see Figure 6 The difference between this embodiment and Embodiment 1 is that the Y-axis moving assembly 14 and the Z-axis moving assembly 13 are provided with guide rods 21 extending along the length direction on their sides, and self-lubricating bushings 22 are fixedly provided on the Y-axis moving assembly 14 and the X-axis moving assembly 15, and the self-lubricating bushings 22 are sleeved on the guide rods 21. With this arrangement, the sliding fit between the self-lubricating bushings 22 and the guide rods 21 can enhance the structural strength between the X-axis moving assembly 15, the Y-axis moving assembly 14 and the Z-axis moving assembly 13, so that the milling cutter disc 19 can be stably adjusted and moved.

[0034] Example 3 Please see Figure 7 The difference between this embodiment and Embodiment 1 is that the surface of the movable plate 2 is provided with a guide rail 23 extending along the X-axis moving assembly 15. A movable plate 24 is slidably mounted on the guide rail 23. A clamping member 25 is provided on the movable plate 24. The clamping member 25 includes two vertical plates. A threaded rod is threadedly mounted on the vertical plates. A clamping piece is provided at the inner end of the threaded rod. With this configuration, the clamping member 25 can clamp and fix medium-sized workpieces or components that are inconvenient to put into the unloading assembly 10. The workpiece is moved to the milling cutter disc 19 for weld grinding by the cooperation of the guide rod 21 and the movable plate 24.

[0035] Example 4 Please see Figure 8 The difference between this embodiment and embodiment one is that the surface of the movable plate 2 is provided with several threaded holes, and several threaded rods are installed in the threaded holes. Through the threaded engagement between the threaded rods and the threaded holes, the threaded rods can be installed onto the surface of the movable plate 2 in a regular manner. With the use of the pads, the threaded rods and pads can limit and fix the large workpiece. Then, through the cooperation of the X-axis moving assembly 15, the Y-axis moving assembly 14 and the Z-axis moving assembly 13, the movement of the milling cutter 19 is adjusted, so that the milling cutter 19 can grind the weld seam on the surface of the large workpiece.
