[0017] Beneficial Effects

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] When the movable ring is in contact with the vertical plate, the spring is continuously pulled to compress the spring, and at the same time, the limiting rod on one side of one of the connecting plates is pulled out of the limiting hole, and then the two connecting plates are driven to rotate by rotating the pulling plate, so as to drive the structural member clamped and fixed between the two connecting plates to adjust the inclination angle. After the inclination angle of the structural member is adjusted, the pulling plate is slowly released. At this time, the limiting plate will be pushed to move to the left under the action of the spring force. When the limiting plate moves, it will drive the first movable rod and the connecting plate to move, and at the same time, it will drive the limiting rod to be inserted into the corresponding limiting hole to fix the inclination angle. The inclination angle of the clamped and fixed structural member can be conveniently adjusted, so as to adapt to the processing requirements of different parts, improve the processing flexibility, and have high practicality.

[0020] 2. The CNC machine tool for processing the structural parts can push the two movable plates to move toward the center position through the hydraulic telescopic rod, and at the same time drive the two fixed frames to move, so that the two sides of the structural parts of different lengths can be clamped. By rotating the handle to drive the first screw rod, the connecting tube and the second screw rod to rotate, the two second movable blocks can be driven to move toward the center position, and at the same time, the two clamping blocks can be driven to clamp the front and rear ends of the structural parts. The first guide rod and the first movable block can ensure that the movable plate and the fixed frame move more smoothly, so that the structural parts to be processed can be clamped and fixed more stably, thereby ensuring that the structural parts will not be displaced during the processing, ensuring the processing accuracy and improving the processing efficiency to a certain extent, and the practicability is high.

[0021] 3. The CNC machine tool for processing structural parts can drive the third screw to rotate through the first servo motor. At this time, the third moving block will drive the moving frame to move downward with the rotation of the third screw, and then drive the processing component to move up and down. The fourth screw can be driven to rotate by the second servo motor. At this time, the fourth moving block will drive the U-shaped moving frame to move left and right with the rotation of the fourth screw, and then drive the processing component to adjust the left and right position. The fifth screw can be driven by the third servo motor to move, which can drive the fifth moving block to move forward and backward, and then drive the processing component to adjust the front and back position. At the same time, the L-shaped rotating plate can be driven to rotate horizontally through the fourth servo motor. The processing component can be driven to adjust the inclination angle through the fifth servo motor. The position of the processing component in the CNC machine body can be conveniently adjusted, and the inclination angle and horizontal rotation angle of the processing component can be adjusted. The position and angle of the processing component can be conveniently adjusted when processing different structural parts, so as to achieve the best processing effect, improve the versatility and adaptability of the CNC machine tool, and have high practicality.

[0022] 4. The CNC machine tool for processing structural parts can make the protective door slide horizontally smoothly through the first slide rail and the second slide rail, and can be opened and closed quickly, which is convenient for operators to load and unload structural parts and adjust the machine tool. At the same time, through the transparent observation window, the processing status of the structural parts can be intuitively observed when the structural parts are processed. The embedded block can be inserted into the sealing groove when the two protective doors are closed and connected, so as to better seal the CNC machine tool body and avoid splashes generated when processing structural parts from flying out of the gap between the two protective doors to cause harm to the operator. The limit block and the fixed stop block can limit the protective doors when the two protective doors are fully opened to avoid the two protective doors from sliding from both sides, which is highly practical.

[0023] 5. The CNC machine tool for processing structural parts can extract the cutting fluid in the filter box under the action of the extraction pipe through the water pump, and then transport it through the delivery pipe and spray it out from the nozzle. When processing the structural parts, the tool and the structural parts in the cutting area can be cooled down to avoid overheating and wear of the tool. At the same time, the deformation of the structural parts due to overheating can be avoided. The debris generated in the cutting process can be flushed down and then fall into the filter box through the rectangular opening. Some larger debris will sink to the bottom after falling into the filter box. At this time, it will be blocked by the baffle, and the cutting fluid will flow from the upper end of the baffle to the center position, and then the fine impurities in the cutting fluid will be filtered by the filter plate. It can be extracted by the extraction pipe for recycling, which is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS

During the movement, the movable ring 18 is fitted with the vertical plate 13 and then continued to be pulled to compress the spring 19. At the same time, the limit rod 22 on one side of one of the connecting plates 21 will be pulled out of the limit hole 14, and then the two connecting plates 21 can be driven to rotate by rotating the pulling plate 20, and then the structural member clamped and fixed between the two connecting plates 21 can be driven to adjust the inclination angle. After the inclination angle of the structural member is adjusted, the pulling plate 20 is slowly released.

At the same time, through the transparent observation window 4, the processing status of the structural parts can be intuitively observed when the structural parts are processed. The embedded block 9 can be inserted into the sealing groove 8 when the two protective doors 3 are closed and connected, so that the CNC machine tool body 1 can be better sealed to prevent splashes generated during the processing of the structural parts from flying out of the gap between the two protective doors 3 to cause harm to the operator. The limit block 10 and the fixed stopper 11 can be set to limit the protective door 3 when the two protective doors 3 are fully opened to prevent the two protective doors 3 from sliding from both sides.

[0042] like Figure 1 , Figure 8 As shown, a CNC machine tool for processing structural parts, a processing component 53 has a pipe clamp 54 detachably connected to one side, a filter box 55 is welded to the lower end of the CNC machine tool body 1, a water pump 56 is detachably connected to the top of the CNC machine tool body 1, an extraction pipe 57 is detachably connected to the upper end of the water pump 56, the other end of the extraction pipe 57 is inserted into the filter box 55, a delivery pipe 58 is detachably connected to the left end of the water pump 56, the other end of the delivery pipe 58 passes through the CNC machine tool body 1 and is clamped in the pipe clamp 54, a nozzle 59 is installed at the lower end of the delivery pipe 58, two rectangular openings 60 are provided at the bottom of the CNC machine tool body 1 and at the top of the filter box 55, the CNC machine tool body 1 is connected to the filter box 55 through the second slide rail 6 limit block 10, two baffles 61 and two filter plates 62 are symmetrically installed in the filter box 55, and two sewage outlets 63 are installed at the front end of the filter box 55.

When processing the structural parts, the tool and the structural parts in the cutting area can be cooled down to avoid overheating and wear of the tool and deformation of the structural parts due to overheating. The debris generated in the cutting process can be washed down and then fall into the filter box 55 through the rectangular opening 60.

At this time, it will be blocked by the baffle 61, and the cutting fluid will flow from the upper end of the baffle 61 to the center position, and then the fine impurities in the cutting fluid will be filtered by the filter plate 62, and then it can be extracted by the extraction pipe 57 for recycling.

[0044] It should be noted that the present invention is a CNC machine tool for processing structural parts. When in use, the structural part to be processed is placed between the two connecting plates 21, and then the first connecting plate 25 and the movable plate 26 are pushed to move toward the center position by the two hydraulic telescopic rods 24.

At the same time, when the movable plate 26 moves, it will drive the fixed frame 29 to move until the two fixed frames 29 clamp the two sides of the structural part. Then, the first screw rod 31, the connecting tube 32 and the second screw rod 33 are driven to rotate by rotating the handle 30. Since the thread directions of the first screw rod 31 and the second screw rod 33 are opposite, when the first screw rod 31 and the second screw rod 33 rotate, the two second movable blocks 34 will be driven to move toward the center position, and then the two clamping blocks 35 can be driven to clamp the front and rear ends of the structural part.

[0045] After the structural part is clamped, the pulling plate 20 is manually pulled to drive the first movable rod 15, the second movable rod 16 and the two connecting plates 21 to move to the right, and at the same time, the limit plate 17 will be driven to move to the right. When the limit plate 17 moves, the spring 19 will be compressed under the action of the movable ring 18 and the vertical plate 13. When the connecting plate 21 moves, the limit rod 22 will be pulled out of the limit hole 14, and then the two connecting plates 21 and the structural part can be driven to adjust the inclination angle by rotating the pulling plate 20. After adjusting to the appropriate inclination angle, slowly release the pulling plate 20. At this time, under the action of the elastic force of the spring 19, the limit plate 17 will be pushed to move to the left, and at the same time, the first movable rod 15 and the two connecting plates 21 will be driven to move to the left. When one of the connecting plates 21 moves, it will drive the limit rod 22 to be inserted into the corresponding limit hole 14 opened on one side of the vertical plate 13. At this time, the fixing of the inclination angle can be completed, and then the structural part can be processed.

[0046] After the structural member is clamped and fixed and its tilt angle is adjusted, the third screw rod 38 is driven to rotate by the first servo motor 37. At this time, the third moving block 39 can drive the moving frame 40 to move up and down as the third screw rod 38 rotates. At the same time, when the second servo motor 41 drives the fourth screw rod 42 to rotate, the fourth moving block 43 will drive the U-shaped moving frame 44 to adjust the left and right position as the fourth screw rod 42 rotates. When the fifth screw rod 46 is driven to rotate by the third servo motor 45, the fifth moving block 48 will drive the second connecting plate 49 and the processing assembly 53 to adjust the front and rear positions as the fifth screw rod 46 rotates, so that the position of the processing assembly 53 can be conveniently adjusted. At the same time, the fourth servo motor 50 can drive the L-shaped rotating plate 51 to rotate, and the fifth servo motor 52 at the rear end of the L-shaped rotating plate 51 can drive the processing assembly 53 to rotate, so as to drive the processing assembly 53 to rotate horizontally and adjust the tilt angle, so that different positions of the structural member can be processed efficiently, thereby improving the versatility and adaptability of the CNC machine tool.

[0047] After the structural parts are clamped and fixed, the two protective doors 3 can be closed by pulling the handle 5, and the processing can be carried out after the protective doors 3 are closed. Here, when the two protective doors 3 are docked and closed, the embedding block 9 on one side of the protective door 3 will be inserted into the sealing embedding groove 8 opened on the other side of the other protective door 3, which can effectively prevent the splashes generated during the processing of the structural parts from flying out from the gap between the two protective doors 3 to cause harm to the workers. At the same time, during processing, the processing status of the structural parts can be observed through the transparent observation window 4. The first slide rail 2, the second slide rail 6 and the slider 7 can make the horizontal sliding of the protective door 3 more stable. At the same time, under the action of the limit block 10 and the fixed stop block 11, the problem that the two protective doors 3 may slide from both sides when the protective doors 3 are opened can be solved.

[0048] When machining the structural parts, the water pump 56 is turned on to extract the cutting fluid in the filter box 55 through the extraction pipe 57, and then the cutting fluid is transported through the delivery pipe 58 and sprayed out by the nozzle 59, which can effectively cool the tool and the structural parts in the cutting area during machining, thereby solving the problem of damage caused by overheating of the tool and deformation of the structural parts due to overheating. At the same time, the debris generated during cutting can be washed down under the spray of the nozzle 59 and fall into the filter box 55 through the rectangular opening 60. After falling into the filter box 55, some relatively large Large debris will sink to the bottom of the filter box 55. The large debris can be prevented from moving to the middle position by the obstruction of the logistics CNC machine tool body 1, and the upper cutting fluid will flow from the baffle 61 to the middle, and will filter the smaller debris in the cutting fluid when it flows into the filter plate 62. After filtration, the cutting fluid between the two filter plates 62 will be extracted by the extraction pipe 57 for recycling. Here, the debris and cutting fluid in the filter box 55 can be regularly discharged and replaced through the drain port 63 to ensure the processing quality of the structural parts.
