Description

Technical Field

[0001] The present invention relates to the technical field of drilling and milling machines, and particularly to a multifunctional integrated drilling and milling machine tool. Background Art

[0002] An integrated drilling and milling machine is a processing equipment that combines drilling and milling, and can complete multiple processing procedures in one clamping, thereby improving processing efficiency and accuracy.

[0003] When the integrated drilling and milling machine is in use, it usually processes for a long time. During processing, the drill bit needs to be cooled, and the cooling method mostly uses water cooling to reduce the temperature, thereby increasing the service life of the drill bit.

[0004] After retrieval, a Chinese patent with the publication number CN110253296B discloses an integrated drilling and milling multi-process numerical control drilling machine tool. However, there are still the following problems: 1. The motor driving the clamping workbench rotates with the movable plate. When the movable plate rotates in a circle, the connecting wire of the motor will be wound. If the movable plate continues to rotate, the connecting wire of the motor will fall off from the motor, resulting in the clamping assembly being unable to achieve clamping; 2. During the milling or drilling of the workpiece, the coolant used to cool the drill bit will directly fall on the surface and flow around from the surface, resulting in the accumulation of coolant on the surface of the workbench, thereby corroding the workbench and reducing the service life of the workbench; 3. During the milling process, chips will be generated and fall on the clamping workbench. If not cleaned in time, it is easy to change the subsequent processing accuracy, thereby reducing the processing accuracy of the machine tool. Summary of the Invention

A surrounding component for blocking the coolant during workpiece processing is provided on the top outer wall of the outer frame body 1. Dust suction components for adsorbing the chips generated during processing are provided on the top outer walls at the four corners of the outer frame body 1. During use, place the workpiece to be processed on the placing table 22, then use the clamping mechanism to clamp and fix the workpiece to be processed. Then use the surrounding component to surround the placing table 22. Use the drilling and milling module to pre-process the part. After pre-processing, start the adjusting motor 20.

All the motors of this equipment are fixed or slide up and down without rotation, thus avoiding the phenomenon of wire entanglement and further improving the operating stability of the device.

[0027] To achieve the machining of workpieces, in the present invention, the drilling and milling module includes a support frame 3, which is fixed to the bottom inner wall of the inner frame body 4 by bolts. The outer walls on multiple sides of the support frame 3 are slidably connected with sliding seats 7.

The drill bit can be a center drill, a fine twist drill, a rough twist drill, a reamer, or a milling cutter. A cooling assembly for cooling the drill bit is provided at the bottom of the mounting frame 9. When machining a workpiece is required, the drill bit is brought into contact with the workpiece through the power assembly, and then the drilling and milling motor 12 is started, thereby driving the drill bit to rotate.

By providing multiple machining stations, different machining steps of the workpiece can be carried out synchronously, and the required drill bit is installed according to requirements to complete different machining steps, thereby improving the machining efficiency of the workpiece.

[0028] To drive the sliding seat 7 to move up and down, in the present invention, the power assembly includes a lifting motor 6, which is fixed to the top outer wall of the connecting frame 2 by bolts.

[0031] In order to prevent the placing table 22 from rotating, the limiting mechanism in the present invention includes a plurality of clamping blocks 28, which are all welded on the circumferential outer side of the placing table 22, and the plurality of clamping blocks 28 are evenly arranged. A plurality of clamping grooves 29 are evenly opened on the circumferential inner wall of the mounting seat 24, and the clamping blocks 28 can be clamped into the clamping grooves 29. When the clamping blocks 28 are clamped into the clamping grooves 29, the placing table 22 will be clamped in the mounting seat 24, so as to limit the placing table 22 and prevent the placing table 22 from rotating, thereby improving the processing accuracy of the device.

At this time, the first slot 27 and the second slot 38 cooperate to form a transmission shaft, so as to be able to drive the placing table 22 to rotate. When the cleaning motor 34 continues to move upward, it will drive the placing table 22 to move upward, so that the clamping block 28 is separated from the clamping groove 29. At this time, the cleaning motor 34 can drive the placing table 22 to rotate, thereby expanding the chip removal range of the dust suction component.

[0033] In order to prevent the coolant from spilling onto the workbench, in the present invention, the enclosure assembly includes multiple groups of baffle frames. The multiple groups of baffle frames are symmetrically arranged on the top outer wall of the outer frame body 1. Each group of baffle frames includes two second baffles 41. The two second baffles 41 are both rotatably connected to the top outer wall of the outer frame body 1. The two second baffles 41 and a first baffle 21 can form an annular fence. Connecting shafts 44 are welded to the bottoms of the two second baffles 41. One end of each connecting shaft 44 passes through the outer frame body 1 and is respectively key-connected to a second gear 45 and a third gear 46, and the second gear 45 is combined with the third gear 46. A connecting seat 47 is fixed to the top inner wall of the outer frame body 1 by bolts. An unfolding motor 48 is fixed to the bottom of the connecting seat 47 by bolts. The output shaft of the unfolding motor 48 passes through the connecting seat 47 and is fixed to one of the connecting shafts 44. A liquid guiding mechanism for discharging the coolant is provided on the inner wall of one side of each of the multiple second baffles 41. When the workpiece needs to be processed, the unfolding motor 48 is started. The unfolding motor 48 drives one of the connecting shafts 44 to rotate. When the second gear 45 meshes with the third gear 46, the two connecting shafts 44 will rotate synchronously, and then the two second baffles 41 will rotate, so as to form an annular fence with the first baffle 21. The splashed coolant will fall on the fence and flow out through the liquid guiding mechanism, thus preventing the coolant from falling onto the workbench and also preventing the coolant from accumulating on the placing table 22, which affects the processing of the workpiece, and thereby improving the service life of the machine tool. After the workpiece is processed at this station, the unfolding motor 48 is started to reverse the unfolding motor 48, thereby opening the two second baffles 41, preventing the second baffles 41 from blocking the rotation of the workpiece, making the operation of the device more smooth, and at the same time facilitating the removal of the workpiece from the placing table 22.

[0034] In order to prevent the coolant from accumulating in the annular fence, in the present invention, the liquid guiding mechanism includes an installation groove. The installation groove is opened on the inner wall of one side of the second baffle 41. A material guiding box 43 is welded in the installation groove. A filter screen 49 is fixed to the middle part of the material guiding box 43 by bolts. A connecting hose 40 is fixed to the lower end of the outer wall of one side of the material guiding box 43 by a clamp, and the connecting hose 40 is communicated with the inside of the material guiding box 43, and the connection point is located below the filter screen 49. The other end of the connecting hose 40 is fixed to a water tank 39 by a clamp, and the water tank 39 is fixed to the outer frame body 1. The coolant carrying a part of the debris flows into the material guiding box 43. After being filtered by the filter screen 49, the coolant flows into the connecting hose 40 from below the filter screen 49, and then flows into the water tank 39 again. The coolant in the water tank 39 can be recycled, reducing the processing cost of the factory and facilitating the subsequent treatment of the coolant.

[0035] To clean up debris, the dust suction component in the present invention includes a fixed seat 42, which is fixed to the top outer wall of the outer frame 1 by bolts. Two symmetrical guide grooves 50 are provided on one outer wall of the fixed seat 42. A moving frame 57 is slidably connected in the guide grooves 50. A dust suction head 52 is fixed between the inner walls on both sides of the moving frame 57 by bolts. An external hose 51 is fixed to the back of the dust suction head 52 by a clamp, and the external hose 51 is connected to an external vacuum cleaner. At both ends of one side of the moving frame 57, support rods 53 are welded. A rolling groove 54 is provided at the bottom of the support rod 53, and a ball 55 is rotatably connected in the rolling groove 54. The ball 55 can reduce the frictional loss between the support rod 53 and the placement table 22, thereby improving the service life of the device. Start the external vacuum cleaner, so that the dust suction head 52 can have suction force to suck the debris into the vacuum cleaner. During the upward movement of the placement table 22, the placement table 22 will drive the support rod 53 and the moving frame 57 to move upward synchronously, so that the dust suction head 52 always maintains a certain distance from the placement table 22. When the placement table 22 rotates, it will drive the debris to rotate together, thereby changing the position of the debris, so that the dust suction head 52 can adsorb the debris and improve the cleaning effect of the device. The two symmetrically arranged support rods 53 can make one of the support rods 53 located at the sliding groove 23 while the other support rod 53 can provide support, preventing the moving frame 57 from resetting and jamming the rotation of the placement table 22, and further improving the smoothness of the device operation.

[0036] When the present invention is in use, it is divided into the following steps: S1: Place the workpiece to be processed on the placement table 22, rotate the fixing screw 31, so that the fixing screw 31 rotates in the threaded hole 32. Under the action of the thread, the fixing screw 31 moves downward, so that the rubber pad 33 contacts the sliding groove 23, thereby fixing the slider 25, and further clamping the workpiece by the clamping seat 30; S2: When the workpiece needs to be processed, start the unfolding motor 48. The unfolding motor 48 drives one of the connecting shafts 44 to rotate. When the second gear 45 meshes with the third gear 46, the two connecting shafts 44 will rotate synchronously, and further rotate the two second baffles 41, so as to form an annular fence in combination with the first baffle 21; S3: Start the lifting motor 6. The lifting motor 6 drives the lead screw 5 to rotate. Under the action of the thread and the connecting frame 2, the sliding seat 7 moves downward, so as to synchronously adjust the heights of the drills at multiple stations. Start the drilling and milling motor 12, and then drive the drill to rotate. Adjust the position of the drill through the three-axis linear module 8 to process the workpiece, and use coolant to cool the drill during the processing. The air nozzle 14 will blow the coolant and the debris together to the material guide box 43; S4: A part of the debris is carried by the coolant and flows into the material guide box 43. After being filtered by the filter screen 49, the coolant flows into the connecting hose 40 from below the filter screen 49, and then flows back into the water tank 39 again; S5: After the workpiece at this station is processed, start the lifting motor 6. The lifting motor 6 drives the lead screw 5 to rotate. Under the action of the thread and the connecting frame 2, the sliding seat 7 moves upward, so that the height of the drill bit is reset; S6: While the sliding seat 7 moves upward, start the position adjustment motor 20. The position adjustment motor 20 drives the first gear 19 to rotate, which drives the internal gear ring 18 to rotate, and then drives the rotating ring 17, the connecting frame 2 and the mounting seat 24 to rotate synchronously, so that the workpiece rotates by a certain angle for the next process. At this time, a new workpiece to be processed can be placed at its subsequent station, and a new workpiece to be processed is placed; S7: During the process of placing the new workpiece, start the cylinder 56 and the external vacuum cleaner. The cylinder 56 drives the fixed disk 35 to move upward, and then drives the cleaning motor 34 to move upward. The cleaning motor 34 drives the plug 36 to move upward. First, the plug 36 will be inserted into the lower joint 26. At this time, the first slot 27 and the second slot 38 cooperate to form a transmission shaft, so that the placing table 22 can be driven to rotate. The cleaning motor 34 continues to move upward, which will drive the placing table 22 to move upward, and then the clamping block 28 will be disengaged from the clamping slot 29. At this time, the cleaning motor 34 can drive the placing table 22 to rotate; S8: When the output shaft of the cleaning motor 34 drives the placing table 22 to rotate, it will drive the debris to rotate together, and then change the position of the debris, so that the dust suction head 52 can adsorb the debris and complete the cleaning of the surface of the placing table 22; S9: In this way, after the workpiece to be processed is completely processed, it will return to the initial position. The processed workpiece is taken out, and a new workpiece to be processed is placed again, and the workpiece can be continuously processed.
