[0034] The following will detail the specific implementation manners of the present disclosure with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only for explaining and illustrating the present disclosure, and are not used to limit the present disclosure.

[0035] In the present disclosure, unless otherwise stated, the orientation terms such as "upper, lower, front, rear, left, and right" are defined for facilitating the description of the drawing directions according to the corresponding drawings, and "inner and outer" are defined according to the contour of the corresponding component itself. The terms such as "first and second" used in the present disclosure are for differentiating one element from another, and do not have sequence and importance. In addition, when the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0036] Please refer to Figures 1 to 3 , an automatic processing device for removing steel plate cutting burrs provided by an embodiment of the present disclosure includes a frame 100, an X-direction moving mechanism 210, a Y-direction moving mechanism 220, a fixture mechanism 300, a cutting mechanism 400, and a tool changing mechanism 500. Among them, the X-direction moving mechanism 210 is installed on the frame 100. The Y-direction moving mechanism 220 is installed on the frame 100 through the X-direction moving mechanism 210, and the Y-direction is perpendicular to the X-direction. The fixture mechanism 300 is installed on the frame 100 for clamping the steel plate 10. The cutting mechanism 400 is fixedly connected to the Y-direction moving mechanism 220 and is located on one side of the steel plate 10 close to the cutting burr 11, and the cutting mechanism 400 is used for cutting the cutting burr 11. The tool changing mechanism 500 is installed on the frame 100 for providing a tool 560 to the cutting mechanism 400.

[0037] It can be understood that the X-direction moving mechanism 210 is installed on the frame 100 to achieve precise movement in the front and rear directions; the Y-direction moving mechanism 220 is installed on the frame 100 through the X-direction moving mechanism 210 and is perpendicular to the X-direction to achieve precise movement in the left and right directions; the fixture mechanism 300 is installed on the frame 100 for firmly clamping the steel plate 10; the cutting mechanism 400 is fixedly connected to the Y-direction moving mechanism 220 and is located on one side close to the cutting burr 11 of the steel plate 10, and can move and cut precisely as needed; the tool changing mechanism 500 is installed on the frame 100 for providing a tool 560 for cutting. The working principle is: through the coordinated action of the X-direction and Y-direction moving mechanisms 220, the fixture mechanism 300 clamps the steel plate 10, and the cutting mechanism 400 moves at a precise position and uses the tool 560 provided by the tool changing mechanism 500 to cut off the cutting burr 11 on the steel plate 10, improving the cutting efficiency of the cutting burr 11.

[0038] In one embodiment, please refer to Figures 10 to 15, the machine frame 100 is formed with a processing position 110. An avoidance groove 120 is provided at the bottom of the processing position 110, and the steel plate 10 is placed above the avoidance groove 120. The fixture mechanism 300 includes a downward pressing component 310, an X-direction pushing component 320, and an X-direction positioning surface switching component 330. Among them, the downward pressing component 310 is installed on the side of the machine frame 100 away from the cutting burr 11 for pressing down the steel plate 10. The X-direction pushing component 320 is installed in the avoidance groove 120. The X-direction positioning surface switching component 330 is arranged in the avoidance groove 120 in X-direction misalignment with the X-direction pushing component 320. The X-direction pushing component 320 and the X-direction positioning surface switching component 330 are used to clamp the steel plate 10 in the X direction. The working principle is as follows: First, the steel plate 10 is placed above the avoidance groove 120, and the downward pressing component 310 presses down the steel plate 10 tightly to ensure its stability. Then, the X-direction pushing component 320 and the X-direction positioning surface switching component 330 work together to move and precisely position the steel plate 10 along the X-axis direction, providing precise clamping to ensure the high-precision requirements during the subsequent removal of the cutting burr 11.

[0039] In an embodiment, please refer to Figures 10 to 12 , there are multiple downward pressing components 310, which are arranged at intervals along the Y direction to ensure the stability and reliability of downward pressing. The downward pressing component 310 includes a first standard oil cylinder 311, a first pressing plate 312, a downward pressing support, and a pressing head 314. The first standard oil cylinder 311 is installed on the machine frame 100, and the output shaft of the first standard oil cylinder 311 is hinged to one end of the first pressing plate 312. The other end of the first pressing plate 312 is installed with the pressing head 314, and the pressing head 314 is used to abut against the top surface of the steel plate 10. The middle part of the first pressing plate 312 is hinged to the downward pressing support, and the bottom of the downward pressing support 313 is fixedly connected to the machine frame 100. Specifically, there can be four downward pressing components 310, whose function is to stably clamp the steel plate 10 on the positioning block; the main clamping (downward pressing component 310) form is a swing rod hinge type; the main clamping oil cylinder is installed on the machine frame 100 through 4 M24 screws. The front end of the oil cylinder piston rod is connected with the joint through an external thread, the joint and the first pressing plate 312 are connected through a pin shaft, the first pressing plate 312 and the downward pressing support are connected through a connecting plate and a pin shaft, the pressing head 314 and the first pressing plate 312 are connected through a pin shaft, and the downward pressing support is installed on the machine frame 100. The oil cylinder and the downward pressing support are fixed. When the oil cylinder piston rod extends, the pressing plate swings around the pin shaft, and the pressing head 314 swings downward to achieve the clamping action. When the oil cylinder piston rod retracts, the pressing head 314 swings upward to achieve the loosening action.

[0040] The fixture mechanism 300 may further include a base. The downward pressing component 310, the X-direction pushing component 320, and the X-direction positioning surface switching component 330 are all installed on the machine frame 100 through the base. Users can first assemble the components used in the fixture mechanism 300 on the base and then directly fix the base on the machine frame 100.

[0041] In one embodiment, please refer to Figure 10 and Figure 15 , the X-direction pushing component 320 includes a second standard oil cylinder 321, a connecting block 322, a rotary oil cylinder 323 and a second pressing plate 324. The second standard oil cylinder 321 is installed in the avoidance groove 120 through an oil cylinder seat. The output shaft of the second standard oil cylinder 321 is fixedly connected to the connecting block 322. A rotary oil cylinder 323 is installed at one end of the connecting block 322 away from the second standard oil cylinder 321. The output shaft of the rotary oil cylinder 323 is installed with the second pressing plate 324. The second pressing plate 324 is used to abut against the X-direction of the steel plate 10.

[0042] Specifically, the X-direction pushing component 320 is composed of a standard oil cylinder with a cylinder diameter of 40 mm, a rotary oil cylinder 323, an oil cylinder seat, a pressing plate, a guide shaft 333, a guide rail seat and a bearing seat 334. There are three sets of X-direction pushing in total. The X-direction pushing component 320 and the X-direction positioning surface switching component 330 act together to clamp the steel plate 10 in the front and back directions. The second standard oil cylinder 321 is installed on the oil cylinder seat, and the oil cylinder seat is fixed on the fixture body. The standard oil cylinder drives the rotary oil cylinder 323 and the second pressing plate 324 to move back and forth through two guide shafts 333 to achieve the pushing action. The rotary oil cylinder 323 is installed on the movable oil cylinder seat. When loading, the standard oil cylinder is in the extended state, and the rotary oil cylinder 323 is also in the extended horizontal state. When it is necessary to push the steel plate 10, the rotary oil cylinder 323 swings up and retracts, and then the standard oil cylinder retracts (i.e., in the vertical state), and the steel plate 10 is pushed against the X-direction reference surface for positioning.

[0043] In one embodiment, please refer to Figures 10 to 16 , the X-direction positioning surface switching component 330 includes a third standard oil cylinder 331, a limit block 332, a guide shaft 333, a bearing seat 334 and an L-shaped positioning block 335. The third standard oil cylinder 331 is installed in the avoidance groove 120 through an oil cylinder seat. The output shaft of the third standard oil cylinder 331 passes through the limit block 332 and is slidably connected to the limit block 332. The end of the output shaft of the third standard oil cylinder 331 is fixedly connected to the L-shaped positioning block 335. The vertical side wall of the L-shaped positioning block 335 is used to abut against the X-direction of the steel plate 10, and the horizontal side wall of the L-shaped positioning block 335 is used to support the steel plate 10. The guide shaft 333 is installed in the avoidance groove 120 through a guide rail seat. The L-shaped positioning block 335 is slidably connected to the guide shaft 333 through a slider. In this way, the switching of the X-direction positioning surface is realized, and the processing surfaces of steel plates 10 with different widths are satisfied to meet the processing requirements by switching the positioning surface; the positioning of the steel plate 10 is divided into two gears. For the steel plate 10 with a width of 320 mm - 475 mm, the X-direction positioning oil cylinder needs to retract. For the steel plate 10 with a width of 150 mm - 320 mm, the X-direction positioning oil cylinder needs to extend; the X-direction reference positioning surface switching mechanism is fixed on the fixture body through mounting screws.

[0044] In one embodiment, please refer toFigure 10 and Figure 13 The fixture mechanism 300 further includes a plurality of steel plate positioning blocks 340 disposed above the avoidance groove 120. The top surface of the steel plate positioning blocks 340 forms a grid surface and a stripe surface. Specifically, it is composed of 6 steel plate positioning blocks 340. The arrangement positions of the steel plate positioning blocks 340 on the fixture are considered to ensure that the steel plate 10 with a length of 800 - 1700 mm, a width of 147 - 475 mm, and a thickness of 70 - 140 mm can be positioned and placed on the fixture. When loading, the steel plate 10 is directly placed on the steel plate positioning blocks 340 of the fixture mechanism 300 through a large electromagnet. In order to increase the friction between the steel plate 10 and the positioning blocks, since the lower surface of the steel plate 10 is not very smooth, considering the situation of avoiding material jamming when pushing against the steel plate 10, the positioning blocks are made into two kinds of pattern effects, and the surface of the positioning blocks is made into a grid surface form and a stripe form; each positioning block is installed on the fixture body through 4 M10 screws.

[0045] In an embodiment, please refer to Figure 10 and Figure 14 The fixture mechanism 300 further includes a plurality of auxiliary support oil cylinders 350. The plurality of auxiliary support oil cylinders 350 are arranged at intervals along the Y direction on the frame 100 and are disposed at one end of the cutting burr 11 of the steel plate 10 for supporting the steel plate 10. Its function is to support the wider steel plate 10; for the steel plate 10 with a width of about 475 mm, after being positioned and clamped on the fixture, there is a certain width dimension below the processing surface side that cannot be supported by the steel plate positioning blocks 340, so vibration will occur during processing. In order to reduce the vibration of the steel plate 10 and increase the stability of positioning and clamping, auxiliary support oil cylinders 350 are added below the processing surface side. After the main clamp clamps the workpiece, the front end of the auxiliary support extends out through the oil circuit to support under the steel plate 10. The auxiliary support oil cylinders 350 are installed on the fixture body through 4 M10 screws; In an embodiment, please refer to Figure 10 The fixture mechanism 300 further includes a Y - direction blocking block 360. The Y - direction blocking block 360 is installed on the frame 100 and is used to abut against the Y direction of the steel plate 10. Since the machining cutting force is relatively large and there is no positioning and clamping in the Y direction, a blocking block is needed during the machining process to ensure that the steel plate 10 will not fall out of the fixture when the cutting force is greater than the clamping force.

[0046] Please refer to Figures 10 to 15 and Figure 18, before loading the steel plate 10, the size of the steel plate 10 is identified through the loading platform, and the size information of the steel plate 10 is sent to the processing equipment. If the width dimension of the steel plate 10 is greater than or equal to 320 mm, the oil cylinder of the X-direction positioning surface switching component 330 retracts. If the width dimension of the steel plate 10 is less than 320 mm, the oil cylinder of the X-direction positioning surface switching component 330 extends, and the reference surface is switched; the positioning switching action corresponds to the X-direction positioning surface switching component 330, the rotation clamping / loosening action is the rotation oil cylinder 323 at the front end of the X-direction push, the push clamping / loosening action is the standard oil cylinder of the X-direction push component 320, the main clamping / loosening action is the action of the main clamping mechanism oil cylinder, and the auxiliary clamping / loosening action is the auxiliary support mechanism; Advantages of the fixture mechanism 300: 1. This fixture solves the problem that the steel plate 10 within the required size range can be clamped and positioned.

[0047] 2. This fixture can meet the problem of machining and cutting of steel plates 10 with different width dimensions through the switching of the X-direction positioning surface switching component 330.

[0048] 3. This mechanism can be widely applied to the processing equipment of steel plates 10.

[0049] 4. This fixture has strong rigidity and can meet the requirements of heavy cutting.

[0050] In an embodiment, please refer to Figures 1 to 3 and Figure 6, the cutting mechanism 400 includes a first motor 410, a small pulley 420, a large pulley 430, a synchronous belt 440, a mechanical main shaft 450, and a tool clamping cylinder 460. The first motor 410 is mounted on the slide plate of the Y-direction moving mechanism 220 through a motor bracket. The small pulley 420 is sleeved on the outer periphery of the output shaft of the first motor 410 and is fixedly connected to the output shaft of the first motor 410. The large pulley 430 is sleeved on the rear end of the mechanical main shaft 450. The synchronous belt 440 is wound around the small pulley 420 and the large pulley 430. The tool clamping cylinder 460 is mounted on the motor bracket and is located at the rear end of the mechanical main shaft 450. The tool clamping cylinder 460 is used to loosen the tool 560 on the front end of the mechanical main shaft 450. Here, the small pulley 420 and the large pulley 430 refer to the diameters of the pulleys. The tool clamping cylinder 460 is mounted on the motor bracket; the rated speed of the motor is 590 r / min, and the output speed of the main shaft is reduced through the synchronous belt 440 pulley pair. The reduction ratio is 34:72, and the rated speed of the main shaft is reduced to 278 r / min; the specification of the mechanical main shaft 450 is BT50. In order to realize the automatic tool change function, a tool clamping cylinder 460 is configured at the rear end of the main shaft; the tool clamping cylinder 460 is mounted on the motor bracket at the rear end of the mechanical main shaft 450. When changing the tool, the main shaft needs to be positioned, so a main shaft positioning recognition switch is configured at the rear end of the main shaft; the main shaft component is connected and mounted to the slide table component through the X-axis guide rail; specifically, the tool clamping cylinder 460 provides thrust through the hydraulic system to push the draw bar forward, thereby loosening the fixture on the main shaft and realizing the replacement of the tool 560. In this process, the main shaft remains fixed, and the tool clamping cylinder 460 offsets the axial force during the tool change process through its internal mechanical structure (such as a disc spring and a locking mechanism), thereby protecting the main shaft bearing from damage.

[0051] In one embodiment, please refer to Figure 6 , the cutting mechanism 400 further includes a main shaft positioning switch 470 and a first sensor 480. The main shaft positioning switch 470 and the first sensor 480 are mounted on the rear end housing of the mechanical main shaft 450. The first sensor 480 is used to detect the rotation of the rotating shaft of the mechanical main shaft 450, and the main shaft positioning switch 470 is used for main shaft positioning. The first sensor 480 determines whether the synchronous belt 440 is broken by identifying whether the mechanical main shaft 450 rotates when the motor rotates. The working principles of the main shaft positioning switch 470 and the first sensor 480 are prior art and will not be described in detail here.
