Description

Technical Field

[0001] The invention relates to the technical field of laser processing equipment, in particular to a laser five-axis tool processing machine tool. Background Art

[0002] Nowadays, hard cutting, dry cutting, high-speed and efficient processing have become important symbols of modern cutting technology, and have driven the overall improvement of cutting processing technology and become the key technology of CNC processing. Tool products have developed into high value-added, high-tech products, containing the latest achievements in contemporary materials, information science, computers, and microelectronics application technology.

[0003] The tool industry collectively refers to super-hard tools, which are mainly made of PCD, CBN, single crystal diamond, natural diamond and other materials. The common characteristics of these materials are high hardness and difficulty in processing, and the advantage is that the tool life is long. Therefore, in the early days when they were used as tool materials, only relatively simple cutting tools could be manufactured. With the advancement of science and technology, the materials and tool manufacturing processes have been expanded more and more widely, and the tool manufacturing process has also undergone a great change. At present, the main characteristics of the progress of tool materials are: on the one hand, cemented carbide has replaced high-speed steel as the main tool material; on the other hand, the proportion of super-hard tool materials has increased significantly.

[0004] Laser processing technology, with its non-contact and high-precision characteristics, has brought new hope to the processing of cemented carbide tools. It is not limited by the hardness of the material and can flexibly realize the processing of complex shapes while maintaining high precision and high efficiency. The heat-affected zone generated by laser technology during the processing is extremely small, which helps to reduce material damage and maintain processing quality.

[0005] The Chinese patent document with publication number CN118616925A discloses a diamond laser processing machine tool, which includes a bed, a gantry arranged on the bed, a first slide and a second slide arranged on the bed slidably forward and backward, a first Y-axis driving mechanism for driving the first slide to move forward and backward, and a second Y-axis driving mechanism for driving the second slide to move forward and backward, a first X-axis saddle is slidably arranged on the gantry, and a first X-axis driving mechanism for driving the first X-axis saddle to move left and right, a first Z-axis saddle is slidably arranged on the first X-axis saddle, and a first Z-axis driving mechanism for driving the first Z-axis saddle to move up and down A Z-axis driving mechanism, wherein the first Z-axis slide saddle is provided with a first laser assembly and a first glue dispensing assembly, the first slide is provided with a first AC-axis turntable, the first AC-axis turntable is provided with a first chuck, the first chuck clamps a first adhesive positioning seat, the second slide is provided with a second AC-axis turntable, the second AC-axis turntable is provided with a second chuck, the second chuck clamps a second adhesive positioning seat, the second adhesive positioning seat is located in front of the first adhesive positioning seat, the first glue dispensing assembly can dispense glue on the second adhesive positioning seat so that the second adhesive positioning seat adheres to the diamond, and the first adhesive positioning seat can adhere to the diamond through glue. It utilizes double-station handover processing to realize continuous processing of diamonds, and can only realize processing operations of diamond planes and inclined surfaces during the processing of diamonds, and cannot realize processing of spiral surfaces and complex curved surfaces of cutting tools. At the same time, the laser processing machine tool needs operators to perform when placing blanks, and the clamping accuracy is low, and the clamping time is long, which leads to extended waiting time of the laser processing machine tool and reduced processing efficiency.

[0006] A Chinese patent document with publication number CN106112704A discloses a tool grinder with a laser coating function, which includes a bed and a grinding processing equipment arranged on the bed, the bed is further provided with a laser coating equipment, the laser coating equipment is composed of a frame fixed to the bed, a cladding head fixing frame assembled on the slideway of the frame, a driving cylinder connected between the cladding head fixing frame and the frame, and a laser cladding head, the top surface of the cladding head fixing frame is provided with a positioning key for limiting horizontal displacement, the bottom of the fixing seat of the laser cladding head is provided with a positioning ring matching the positioning key, the laser cladding head is fixed to the cladding head fixing frame by the positioning key and the positioning ring, the top of the fixing seat of the laser cladding head is provided with a cladding grabbing head, and the lower part of the spindle box of the grinding processing equipment is provided with a hydraulic automatic broaching mechanism corresponding to the cladding grabbing head. Although the tool grinder is equipped with a material tray on the grinder bed, the removal and placement of the tool still requires the operator to complete the clamping accuracy. Since the tool undergoes cladding processing and the surface temperature is high, there is a safety risk when removing the tool. In addition, the high temperature environment of the cladding processing has a certain impact on the drive mechanism, reducing the processing accuracy.

[0007] Taking advantage of CNC machining technology represented by turning machining centers and boring and milling machining centers, performing centralized machining of multiple processes for complex parts in one installation, and blurring the boundaries of different cutting processes such as traditional turning, milling, boring, and threading are currently important ways to improve the efficiency of CNC machine tools and accelerate product development. To this end, new requirements are also put forward for tools. In addition to tool modularization, it is also required that a tool should complete the machining of different processes of parts as much as possible. Reduce the number of tool changes and save time for frequent tool changes; special and efficient tools have become the characteristics of modern automatic production lines, playing an important role in reducing investment costs, ensuring production rhythm and product quality. The development of multifunctional composite tools is another trend in the current development of tool structure.

[0008] The important characteristics of the development of multifunctional composite tools, such as carbide tools, are specialization, compounding and multifunctionality, which lead to increasingly complex tool structures, peculiar shapes, and complex and time-consuming processing. Although traditional processing methods, especially grinding wheel grinding, can cope with most materials, they are powerless when facing carbide, with low efficiency and limited processing accuracy. Traditional tool processing equipment can no longer guarantee the processing accuracy and efficiency of multifunctional composite tools, and it is difficult to meet the growing market demand.

The setting of the left mounting hole 26 and the right mounting hole 27 can also reduce the weight of the mounting seat 17, thereby reducing the load of the mechanical arm 16 and extending the service life of the mechanical arm 16.

[0044] Embodiment 5: As an optimization of the above embodiment, as shown in the attached Figures 1 to 6, as shown in FIGS. 8 to 11, the front swing device includes a mandrel 30, a piston 31, a swing arm 32 and a cylinder block 33. A mandrel 30 that is front-rearward and tubular is fixedly installed inside the left part of the mounting seat 17. A cylinder block 33 that can move back and forth within the mounting groove 23 is hermetically sleeved outside the middle part of the mandrel 30. A piston 31 is hermetically and fixedly installed outside the middle part of the mandrel 30. The outside of the piston 31 is in sealed contact with the inner wall of the cylinder block 33. Front air outlets 34 and rear air outlets 35 that are internally and externally connected are provided outside the mandrel 30 at positions corresponding to the front and rear of the piston 31. A sealing plug 36 is fixed inside the mandrel 30 at a position corresponding to the middle between the front air outlets 34 and the rear air outlets 35. Oval swing grooves 37 that open outward are provided on both the left and right sides of the cylinder block 33. A connecting pin 38 is provided in each swing groove 37. The swing arm 32 is in a U shape with an upward opening. The left and right upper parts of the swing arm 32 are respectively installed together with the corresponding connecting pins 38. A swing hole that penetrates left and right is provided on the right side of the lower part of the swing arm 32. The left part of the front rotating shaft 28 is sleeved within the swing hole. The rear swing device 39 has the same structure as the front swing device.

[0045] According to requirements, the cylinder block 33 includes a front end cover, a cylinder liner and a rear end cover that are sequentially sleeved outside the mandrel 30 from front to rear. The rear end of the front end cover is fixedly installed together with the front end of the cylinder liner. The front end of the rear end cover is fixedly installed together with the rear end of the cylinder liner. Sealing rings are provided between the centers of the front end cover and the rear end cover and the outside of the mandrel 30, so as to ensure that the cylinder block 33 is always in sealed contact with the outside of the mandrel 30 when moving back and forth. At the same time, an annular sealing groove is provided outside the piston 31, and an O-ring is installed in the sealing groove, so as to ensure that the inner wall of the cylinder block 33 is always in sealed contact with the outside of the piston 31 when moving back and forth. This can prevent air leakage during the transfer process after clamping the workpiece to be processed or the processed tool 44, which may cause the clamping force between the front active finger 20 and the front driven finger 18 to decrease, resulting in the workpiece to be processed or the processed tool 44 falling. For the convenience of machining the sealing plug 36, the sealing plug 36 is integrally provided with the mandrel 30. Two holes can be drilled along the axis at the end of the cylinder respectively, and the two holes are not connected to each other, so as to form the mandrel 30 with the sealing plug 36.

[0046] In order to make the structure of the material transfer assembly more compact, the swing groove 37 of the cylinder 33 in the front swing device and the swing groove 37 of the cylinder 33 in the rear swing device 39 are staggered front and back, so that the swing arms 32 in the front swing device and the rear swing device 39 can avoid mutual interference during the swinging process. In order to improve the efficiency of taking and placing the material to be processed or the processed tool 44, the front active finger 20 and the front driven finger 18 are used to load the material to be processed into the cradle five-axis turntable 2, and the rear active finger 21 and the rear driven finger 19 are used to insert the processed tool 44 into the storage hole 14. In this way, two clamping stations are set, and the mounting seat 17 can realize the picking and placing operation of the material to be processed or the processed tool 44 with the mechanical arm 16 moving back and forth between the storage tray 11 and the cradle five-axis turntable 2, avoiding multiple back and forth movements that cause the waiting time of the machine tool to be extended, and can improve the processing efficiency.

[0047] When air is ventilated into the front end of the core shaft 30, the gas enters the cylinder body 33 in front of the piston 31 through the front end of the core shaft 30 and the front air outlet 34. After the pressure in the cavity in front of the piston 31 is greater than the pressure in the cavity behind the piston 31, the cylinder body 33 moves forward. When the cylinder body 33 moves forward, it drives the swing arm 32 and the front rotating shaft 28 to swing forward so that the front active finger 20 and the front driven finger 18 move away from each other. In this way, the material to be processed or the processed tool 44 between the front active finger 20 and the front driven finger 18 can be loosened and placed in the cradle five-axis turntable 2 or the storage hole 14.

[0048] When air is ventilated into the rear end of the core shaft 30, the gas enters the cylinder body 33 behind the piston 31 through the rear end of the core shaft 30 and the rear air outlet 35. After the pressure in the cavity in front of the piston 31 is less than the pressure in the cavity behind the piston 31, the cylinder body 33 moves backward. When the cylinder body 33 moves backward, it drives the swing arm 32 and the front rotating shaft 28 to swing backward so that the front active finger 20 and the front driven finger 18 are close to each other, so that the front active finger 20 and the front driven finger 18 can clamp and take out the material to be processed in the cradle five-axis turntable 2 or the storage hole 14 or the processed tool 44.

[0049] The front air outlet 34 and the rear air outlet 35 may be evenly spaced along the circumference with one or more holes. In this embodiment, the number of the front air outlet 34 and the rear air outlet 35 is one. In order to protect the cylinder 33 and the core shaft 30, a dust cover is fixedly installed on the upper side of the mounting seat 17. The swing grooves 37 on the left and right sides of the cylinder 33 are both vertically arranged. The arrangement of the swing grooves 37 enables the connecting pin 38 to move up and down in the swing grooves 37 when the cylinder 33 moves forward and backward, thereby realizing the swing arm 32 to swing along the central axis of the front rotating shaft 28, avoiding the phenomenon of the swing arm 32 swinging unsmoothly.

[0050] Embodiment 6: As an optimization of the above embodiment, as shown in the attached Fig.10As shown, two screw holes communicating with each other are provided at intervals on the left and right sides of the lower side of the swing arm 32 , and a top screw 40 whose upper end abuts against the outer side of the front rotating shaft 28 is screwed into each screw hole.

[0051] During use, by setting the top screw 40, the relative position between the swing arm 32 and the front rotating shaft 28 can be adjusted according to the specifications of the material to be processed or the processed tool 44 clamped between the front active finger 20 and the front driven finger 18. If the specifications of the material to be processed or the processed tool 44 are large, that is, the diameter of the material to be processed or the processed tool 44 is large, the relative position between the swing arm 32 and the front active shaft is adjusted so that when the cylinder body 33 is located in the central position, the two connecting pins 38 of the swing arm 32 are both located at the lower part of the swing groove 37, so that the initial opening width between the front active finger 20 and the front driven finger 18 is large, and a material with a larger diameter can be clamped. The material to be processed or the processed tool 44 is ventilated into the rear end of the core shaft 30, and then the cylinder body 33 moves backward, driving the upper part of the swing arm 32 to swing backward, so that the front rotating shaft 28 swings to reduce the opening between the front active finger 20 and the front driven finger 18, and then the material to be processed or the processed tool 44 is clamped. When the material to be processed or the processed tool 44 needs to be put down, air is ventilated into the front end of the core shaft 30, and then the cylinder body 33 moves forward, driving the upper part of the swing arm 32 to swing forward, so that the front rotating shaft 28 swings to increase the opening between the front active finger 20 and the front driven finger 18, and then the material to be processed or the processed tool 44 is released.

[0052] If the specifications of the material to be processed or the processed tool 44 are small, that is, the diameter of the material to be processed or the processed tool 44 is small, the relative position between the swing arm 32 and the front active shaft is adjusted so that when the cylinder body 33 is located in the central position, the two connecting pins 38 of the swing arm 32 are both located at the upper part of the swing groove 37, so that the initial opening width between the front active finger 20 and the front driven finger 18 is small, and the material to be processed or the processed tool 44 with a smaller diameter can be clamped. In this way, the clamping operation of tools of various specifications can be realized, the adjustment is convenient, and the application range is wide. At the same time, the top screw 40 can also fix the swing arm 32 and the front rotating shaft 28 together, so that the front rotating shaft 28 swings synchronously with the swing arm 32.

[0053] In order to prevent the swing arm 32 from swinging too much after resetting, the left part of the left mounting hole 26 and the right mounting hole 27 are both rectangular, so that when the swing arm 32 contacts the lower inner wall of the left mounting hole 26 when resetting, the left mounting hole 26 can also limit the swing arm 32, which can shorten the swing angle of the swing arm 32 and make the swing time of the swing arm 32 shorter, thereby shortening the time for clamping the material to be processed or the tool 44 after processing.

[0054] Embodiment 7: As an optimization of the above embodiment, as shown in the attached Figure 1 ,3 As shown in Figures 6, 8 to 11, a front air intake hole 41 is provided on the upper left side of the mounting seat 17 corresponding to the front end position of the core shaft 30, and the other end of the front air intake hole 41 is communicated with the front end of the core shaft 30. A rear air intake hole 42 is provided on the upper left side of the mounting seat 17 corresponding to the rear end position of the core shaft 30, and the other end of the rear air intake hole 42 is communicated with the rear end of the core shaft 30. Air pipe joints 43 are fixedly installed on the upper sides of the mounting seat 17 corresponding to the positions of the front air intake hole 41 and the rear air intake hole 42.

[0055] According to the requirements, the outer side of the front end of the core shaft 30 is sealed and fixedly installed on the other end of the front air intake hole 41, and the outer side of the rear end of the core shaft 30 is sealed and fixedly installed on the other end of the rear air intake hole 42. Sealing rings are provided between the outer side of the front end of the core shaft 30 and the inner wall of the front air intake hole 41, and between the outer side of the rear end of the core shaft 30 and the inner wall of the rear air intake hole 42. In order to facilitate the setting of the front air intake hole 41 and the rear air intake hole 42 and the installation between the core shaft 30 and the mounting seat 17, the mounting seat 17 includes a base plate and clamping plates fixedly installed on the front and rear sides of the base plate, the front air intake hole 41 and the rear air intake hole 42 are respectively arranged on the clamping plates, and the two ends of the core shaft 30 are respectively installed together with the clamping plates on both sides, and the air pipe joint 43 is an existing well-known technology, such as an SL air pipe quick joint throttle valve.

[0056] During use, the setting of the air pipe joint 43 is convenient for connecting the two ends of the core shaft 30 with the air source pipeline, and can also adjust the flow rate, thereby adjusting the moving speed of the cylinder body 33, and finally realizing the adjustment of the clamping action speed. When the front end of the forward air intake hole 41 is ventilated, the gas enters the cylinder body 33 in front of the piston 31 through the front air intake hole 41 and the front air outlet hole 34. After the pressure in the cavity in front of the piston 31 is greater than the pressure in the cavity behind the piston 31, the cylinder body 33 moves forward. When the cylinder body 33 moves forward, it drives the swing arm 32 and the front rotating shaft 28 to swing forward so that the front active finger 20 and the front driven finger 18 move away from each other. In this way, the material to be processed or the processed tool 44 between the front active finger 20 and the front driven finger 18 can be loosened and placed in the cradle five-axis turntable 2 or the storage hole 14.

[0057] When air is ventilated into the rear air inlet hole 42, the gas enters the cylinder body 33 behind the piston 31 through the rear air inlet hole 42 and the rear air outlet hole 35. After the pressure in the cavity in front of the piston 31 is less than the pressure in the cavity behind the piston 31, the cylinder body 33 moves backward. When the cylinder body 33 moves backward, it drives the swing arm 32 and the front rotating shaft 28 to swing backward so that the front active finger 20 and the front driven finger 18 are close to each other, so that the front active finger 20 and the front driven finger 18 can clamp and take out the material to be processed in the cradle five-axis turntable 2 or the storage hole 14 or the processed tool 44.

[0058] Embodiment 8: As an optimization of the above embodiment, as shown in the attached Figures 1 to 5As shown, the cradle five-axis turntable 2 is a torque motor cradle five-axis turntable, and the rear part of the column 8 is hollow.

[0059] According to the requirements, the torque motor cradle five-axis turntable is an existing known technology, such as the torque motor cradle five-axis turntable of model DZDC, and the left, rear and right parts of the column 8 are all hollowed out. During use, the torque motor cradle five-axis turntable cooperates with the lower slide 6, the upper slide 7 and the laser processing module 5 to realize the processing of various curved surfaces or planes of the tool, which can reduce the number of tool clamping times and improve the processing accuracy. The rear part of the column 8 is hollowed out, which can reduce the weight of the column 8, thereby reducing the deformation of the column 8 and the bed 1 during the processing process, which affects the processing accuracy of the tool.

[0060] The above technical features respectively constitute various embodiments of the present invention, which have strong adaptability and implementation effect. Non-essential technical features can be added or reduced according to actual needs to meet the requirements of different situations.
