[0017] Technical effects and advantages of the present invention:

[0018] 1. The present invention utilizes a moving assembly to help the moving plate to move horizontally under force, so that the fixture is forced to move in a direction close to the tool. At the same time, the tool moves under the action of the second guide rail. During the movement, the distance between the tool and the fixture gradually decreases, which facilitates the simultaneous movement of the fixture and the tool to the position of the workbench, reduces the time for tool movement, facilitates the alignment and positioning between the workpiece on the fixture and the tool, and increases the efficiency of tool alignment and positioning.

[0019] 2. The present invention utilizes a rotating component to help the U-shaped frame to rotate around the second motor shaft as the axis under the action of the second motor, so that the fixture and the workpiece rotate at the same time, which helps the tool of the CNC machine tool to process the workpiece at an inclined angle. When not rotating, the tool of the CNC machine tool is forced to move in a vertical direction after alignment and positioning. After processing the groove side body, it is necessary to align the tool and the groove side body again. Only after multiple alignments of the tool can the processing of the groove side body be completed. When the groove side body is in an inclined state, the processing surface between the tool and the groove side body is increased, reducing the number of alignments between the tool and the groove side body, and at the same time, reducing the alignment time between the tool and the groove side body.

[0020] 3. The present invention utilizes a lifting and flipping assembly to help the rotating plate to rotate under force. At this time, there is a certain angle between the rotating plate and the U-shaped frame, and the fixture and the groove side body rotate with the rotating plate, so that the fixture and the groove side body are offset as a whole, and a certain angle is generated between the fixture, the groove side body and the tool, which is convenient for the tool to process multiple surfaces of the groove side body, and helps the tool to perform end milling, back milling and other processes on the groove side body, avoiding the need for multiple CNC machine tools to process the groove side body during processing, thereby increasing efficiency. At the same time, it avoids the need to manually disassemble the groove side body from the fixture, adjust the processing angle of the groove side body, and then install and process the groove side body, thereby reducing labor consumption.

[0021] 4. The present invention utilizes a clamping and fixing assembly to help limit and fix the workpiece. When the workpiece is placed on the electromagnet, the electromagnet is electrically connected to the power supply through the power box, so that the electromagnet generates magnetic force. At the same time, the third motor is electrically connected to the power supply, and the third motor drives the rotating column to rotate, which helps the rotating pressure block to rotate to the workpiece and fit with the workpiece. On the one hand, the rotating pressure block fixes the workpiece through the rotational force of the third motor, and on the other hand, the rotating pressure block is attracted by the magnetic force of the electromagnet, so that the rotating pressure block moves in the direction close to the electromagnet, which helps the rotating pressure block to clamp and fix the workpiece through a double force, thereby increasing the stability of the workpiece and causing the workpiece to shake during processing, affecting the processing quality of the workpiece.

[0033] The numerically controlled machine tool 1 moves the tool 16 in vertical and horizontal directions through the first guide rail 6 , the second guide rail 10 , and the third guide rail 14 , which helps to align and position the tool 16 with the groove side body 35 .

[0034] The tool box door 3 is located on the tool box, and some tools, such as a cleaning brush, etc., are placed in the tool box.

[0035] Four supporting legs 2 are provided, and the four supporting legs 2 support the CNC machine tool 1, thereby increasing the stability of the CNC machine tool 1 and preventing the CNC machine tool 1 from vibrating when in use.

[0036] The workbench 4 is rectangular and is used for installing the fixture. The notch 36 on the workbench 4 plays a guiding role, which helps the moving plate 17 to move under force and avoids the moving plate 17 from deflecting during the movement.

[0037] Four support frames 5 are provided for supporting the first guide rail 6 for use.

[0038] Two first guide rails 6 are provided, which are respectively fixedly connected to the support frame 5 and are used for the second guide rail 10 to move under force. The movement of the second guide rail 10 helps to align and position the tool 16 and the groove side body 35. A guide rail is opened on the first guide rail 6.

[0039] The first guide slider 8 is composed of a ball or slider and a supporting structure. The ball or slider is usually fixed through a fixing hole at the bottom of the guide rail to ensure that it maintains contact with the guide rail during movement. The first guide rail 6 is usually made of metal material with high rigidity and stability to support the movement of the ball or slider and withstand the working load. The first guide slider 8 realizes the linear motion of the object through the contact between the ball or slider on the guide rail and the sliding surface on the slider. The ball or slider is usually made of wear-resistant material and has a low friction coefficient to reduce friction loss during movement. The guide rail usually has a straight shape to ensure that the slider moves smoothly thereon.

[0040] The first guide slide block 8 is used in the CNC machine tool to support and guide the linear motion of the tool 16 to achieve precise processing and positioning.

[0041] The first limit block 7 serves as a limiter for limiting the moving range of the first guide slider 8 .

[0042] Taking into account that the groove side is limited and fixed by a clamp and aligned by a tool on a CNC machine tool, which increases the time for tool alignment, a moving component is provided on the top of the workbench 4 in the present invention, and the moving component includes a moving plate 17, and the moving plate 17 is slidably connected to the workbench 4. The two ends of the workbench 4 are respectively fixedly connected with a first fixed triangular block 18 and a second fixed triangular block 21, and the first fixed triangular block 18 is fixedly connected to a first motor 19 by screws on the side away from the workbench 4. A screw rod 20 is fixedly connected to the rotating shaft of the first motor 19, and the moving plate 17 is threadedly connected to the outer ring of the screw rod 20. The screw rod 20 passes through the first fixed triangular block 18 and the second fixed triangular block 21, and is rotatably connected to the first fixed triangular block 18 and the second fixed triangular block 21.

[0043] The movable plate 17 is rectangular in shape. When the movable plate 17 is subjected to force by the screw rod 20 , the movable plate 17 moves on the workbench 4 .

[0044] The first fixed triangular block 18 and the second fixed triangular block 21 are triangular in shape, and threaded holes are provided on both of them to play a supporting role. On the one hand, they are used to be fixedly connected to the first motor 19, and on the other hand, they are used to support the screw rod 20 to rotate under force.

[0045] The present invention utilizes a moving component to help the moving plate 17 to move horizontally under force, so that the fixture is forced to move in the direction close to the tool 16. At the same time, the tool 16 moves under the action of the second guide rail 10. During the movement, the distance between the tool 16 and the fixture gradually decreases, which facilitates the simultaneous movement of the fixture and the tool 16 to the position of the workbench 4, reduces the movement time of the tool 16, facilitates the alignment and positioning between the groove body 35 on the fixture and the tool 16, and increases the efficiency of the alignment and positioning of the tool 16.

[0046] Furthermore, the moving assembly helps to reduce the alignment time between the tool 16 and the groove side body 35. Specifically, the first motor 19 is electrically connected to the power supply, and the first motor 19 drives the screw rod 20 to rotate, so that the moving plate 17 is forced to move on the workbench 4, and the moving plate 17 drives the U-shaped frame 22 to move. When the U-shaped frame 22 is forced to move, the hydraulic cylinder 23 inside the U-shaped frame 22 moves at the same time, the fixed seat 24 moves in the direction of the U-shaped frame 22, the hinged seat moves in the direction of the U-shaped frame 22, and the moving plate 25 moves in the direction of the U-shaped frame 22. The electromagnet 30 moves in the direction of the U-shaped frame 22, the fixed plate 31 moves in the direction of the U-shaped frame 22, the third motor 32 moves in the direction of the U-shaped frame 22, the moving column 33 moves in the direction of the U-shaped frame 22, the moving pressing block 34 moves in the direction of the U-shaped frame 22, and the groove body 35 moves in the direction of the U-shaped frame 22. At the same time, after the CNC machine tool 1 is started, the second guide rail 10 on the CNC machine tool 1 moves along the first guide rail 6 under the action of the guide rail slider 8, and the first connecting frame 9 moves in the direction of the second guide rail 10. The slider 8 moves in the direction of the second guide rail 10, the second limit block 11 and the second guide slider move in the direction of the second guide rail 10, the first connecting block 12 moves in the direction of the second guide rail 10, the second connecting block 13 moves in the direction of the second guide rail 10, the third guide rail 14 moves in the direction of the second guide rail 10, the connecting seat 15 moves in the direction of the second guide rail 10, and the tool 16 moves in the direction of the second guide rail 10. At this time, the fixture, the groove body 35 and the tool 16 move towards each other, and the three will meet in the middle of the workbench 4. After that, the first connecting block 12 is driven to move horizontally by the second guide slider, the second connecting block 13 moves in the direction of the first connecting block 12, the third guide rail 14 moves in the direction of the first connecting block 12, the connecting seat 15 moves in the direction of the first connecting block 12, and the tool 16 moves in the direction of the first connecting block 12, so that the tool 16 is aligned with the groove side body 35, and then the connecting seat 15 is vertically moved on the third guide rail 14 to be aligned with the groove side body 35. After the alignment, the groove side body 35 is processed by the tool 16.

[0047] Considering that after the tool 16 of the CNC machine tool is aligned and positioned and is forced to move in a vertical direction to process the groove side body 35, it is necessary to align and position the tool 16 with the groove side body 35 again. Only through multiple alignment and positioning of the tool 16 can the groove side body 35 be processed. Therefore, the top of the movable plate 17 in the present invention is rotatably connected with a U-shaped frame 22, and the U-shaped frame 22 is U-shaped. A groove 28 and a screw hole 29 are opened inside the U-shaped frame 22. A rotating assembly is arranged inside the groove 28, and the rotating assembly includes a second motor 27. The second motor 27 is fixedly connected to the groove 28, and the U-shaped frame 22 is fixedly connected to the rotating shaft of the second motor 27.

[0048] The U-shaped frame 22 is used to support the clamping and fixing components.

[0049] The present invention utilizes a rotating assembly to help the U-shaped frame 22 to rotate around the rotating shaft of the second motor 27 under the action of the second motor 27, so that the clamp and the groove side body 35 rotate at the same time, which helps the tool 16 of the CNC machine tool to process the groove side body 35 at an inclined angle. When not rotating, the tool 16 of the CNC machine tool processes the groove side body 35 in a vertical direction, and the tool 16 and the groove side body 35 are aligned and positioned through continuous tool movement. When the groove side body 35 is in a tilted state, the processing surface between the tool 16 and the groove side body 35 is increased, thereby reducing the number of alignments between the tool 16 and the groove side body 35, and at the same time, reducing the alignment time between the tool 16 and the groove side body 35.

[0050] Furthermore, the rotating assembly helps the tool 16 to process the groove side body 35 with an inclined angle. Specifically, the second motor 27 is electrically connected to the power supply, the second motor 27 drives the rotating shaft to rotate, and the rotating shaft drives the U-shaped frame 22 to rotate. When the U-shaped frame 22 is subjected to force to rotate, the hydraulic cylinder 23 inside the U-shaped frame 22 rotates at the same time, the fixed seat 24 rotates in the direction of the U-shaped frame 22, the hinged seat rotates in the direction of the U-shaped frame 22, the rotating plate 25 rotates in the direction of the U-shaped frame 22, the electromagnet 30 rotates in the direction of the U-shaped frame 22, the fixed plate 31 rotates in the direction of the U-shaped frame 22, the third motor 32 rotates in the direction of the U-shaped frame 22, the rotating column 33 rotates in the direction of the U-shaped frame 22, the rotating pressure block 34 rotates in the direction of the U-shaped frame 22, and the groove side body 35 rotates in the direction of the U-shaped frame 22, so that the groove side body 35 and the tool 16 are in an inclined state, which helps the tool 16 to process the groove side body 35 with an inclined angle.

[0051] Taking into account that the groove side usually requires CNC machine tools to perform end milling, back milling and other processes, and these processes are processed by different machine tools respectively, resulting in low processing efficiency. Therefore, a lifting and flipping assembly is provided on one side of the second motor 27 in the present invention, and the lifting and flipping assembly includes a hydraulic cylinder 23, and the hydraulic cylinder 23 is rotatably connected to the U-shaped frame 22. The telescopic end of the hydraulic cylinder 23 is hinged with a fixed seat 24, and the top of the U-shaped frame 22 is fixedly connected to two hinged seats, and a rotating plate 25 is rotatably connected between the two hinged seats, and the fixed seat 24 is fixedly connected to the rotating plate 25.

[0052] The hydraulic cylinder 23 is a driving component, and the retractable end of the hydraulic cylinder 23 drives the rotating plate 25 to rotate under force.

[0053] The fixing seat 24 is provided with a square groove, and a column is fixedly connected in the fixing seat 24 . The column and the telescopic end of the hydraulic cylinder 23 are connected to each other, which helps to rotate the telescopic end of the hydraulic cylinder 23 on the column.

[0054] The rotating plate 25 is fixedly connected with a circular shaft at the position of the hinge seat, and the rotating plate 25 is rotatably connected in the hinge seat through the circular shaft.

[0055] The present invention utilizes a lifting and flipping assembly to help the rotating plate 25 to rotate under force. At this time, there is a certain angle between the rotating plate 25 and the U-shaped frame 22, and the fixture and the groove side body 35 rotate with the rotating plate 25, so that the fixture and the groove side body 35 are offset as a whole, and a certain angle is generated between the fixture, the groove side body 35 and the tool, which is convenient for the tool 16 to process multiple surfaces of the groove side body 35, and helps the tool 16 to perform end milling, back milling and other processes on the groove side body 35, avoiding the need for multiple CNC machine tools to process the groove side body 35 during processing, thereby increasing efficiency. At the same time, it avoids the need to manually disassemble the groove side body 35 from the fixture, adjust the processing angle of the groove side body 35, and then install and process the groove side body 35, thereby reducing labor consumption.

[0056] Furthermore, the lifting and flipping assembly helps to perform end milling, back milling and other processes on the groove side body 35. Specifically, the hydraulic cylinder 23 is electrically connected to the power supply, the telescopic end of the hydraulic cylinder 23 is forced to move, the telescopic end of the hydraulic cylinder 23 drives the fixed seat 24 to rotate, the rotating plate 25 is forced to rotate, the electromagnet 30 rotates in the direction of the rotating plate 25, the fixed plate 31 rotates in the direction of the rotating plate 25, the third motor 32 rotates in the direction of the rotating plate 25, the rotating column 33 rotates in the direction of the rotating plate 25, the rotating pressure block 34 rotates in the direction of the rotating plate 25, and the groove side body 35 rotates in the direction of the rotating plate 25, so that a certain angle is generated between the groove side body 35 and the tool 16, which helps to make the end face, back face, etc. of the groove side body 35 contact with the tool 16, and the end face, back face, etc. of the groove side body 35 are processed by the tool 16.

[0057] Taking into account that the CNC machine tool cooperates with the clamp through screws, manual operation is required to limit the groove side body 35, and the operation is complicated. Therefore, a clamping and fixing component is provided on the top of the rotating plate 25 in the present invention, and the clamping and fixing component includes an electromagnet 30, the electromagnet 30 is fixedly connected to the rotating plate 25, and the groove side body 35 is provided on the electromagnet 30. Two fixed plates 31 are provided on both sides of the electromagnet 30, and the fixed plates 31 are fixedly connected to the rotating plate 25. One side of one of the fixed plates 31 is fixedly connected to the third motor 32, and a rotating column 33 is fixedly connected to the rotating shaft of the third motor 32. Two rotating pressure blocks 34 are fixedly connected to the outer ring of the rotating column 33, and the two rotating pressure blocks 34 are located on both sides of the rotating column 33. The bottom of the electromagnet 30 is fixedly connected to the power box 26, and the power box 26 cooperates with the electromagnet 30, which is helpful to energize the electromagnet 30 and generate magnetic force in the electromagnet 30.

[0058] The clamp is composed of a fixed plate 31, a third motor 32, a rotating column 33, and a rotating pressing block 34. The four cooperate with each other to help clamp and fix the groove side body 35.

[0059] Two fixing plates 31 are provided, and circular holes are formed on the two fixing plates 31 . The circular holes are used to support the rotating column 33 to rotate.

[0060] The power box 26 is provided with a power supply for supplying power to the parts on the CNC machine tool 1 .

[0061] The electromagnet 30 is generally composed of an iron core, an armature and an excitation coil. It generates magnetism when power is supplied and loses magnetism when power is disconnected. An energized solenoid is provided in the electromagnet 30. When the iron core is inserted into the energized solenoid, the iron core is magnetized by the magnetic field of the energized solenoid, and the magnetized iron core also becomes a magnet. In this way, the two magnetic fields are superimposed on each other, thereby greatly enhancing the magnetism of the solenoid. In order to make the magnetism of the electromagnet stronger, the iron core is usually made into a horseshoe shape, and the winding direction of the coil on the horseshoe-shaped iron core is opposite, one side is clockwise and the other side must be counterclockwise. The iron core of the electromagnet is made of soft iron.

[0062] The present invention utilizes a clamping and fixing component to help limit and fix the groove side body 35. When the groove side body 35 is placed on the electromagnet 30, the electromagnet 30 is electrically connected to the power supply through the power box 26, so that the electromagnet 30 generates a magnetic force. At the same time, the third motor 32 is electrically connected to the power supply, and the third motor 32 drives the rotating column 33 to rotate, which helps the rotating pressure block 34 to rotate to the groove side body 35 and fit with the groove side body 35. On the one hand, the rotating pressure block 34 fixes the groove side body 35 through the rotational force of the third motor 32. On the other hand, the rotating pressure block 34 is attracted by the magnetic force of the electromagnet 30, so that the rotating pressure block 34 moves in a direction close to the electromagnet 34, which helps the rotating pressure block 34 to clamp and fix the groove side body 35 through a double force. The operation is simple and convenient, and it helps to disassemble the groove side body 35 after processing. When the groove side body 35 is processed, the stability of the groove side body 35 is increased, so that the groove side body 35 shakes during the processing, affecting the processing quality of the groove side body 35.

[0063] The groove body 35 is made of steel and will not be attracted by the magnetic force of the magnet.
