Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, and in particular to a five-axis linkage processing equipment with high-speed drilling. Background Art

[0002] The five-axis linkage machining center, also known as the five-axis machining center, is a high-tech, high-precision machining center specifically used for machining complex surfaces. This machining center system has a significant influence on a country's aviation, aerospace, military, scientific research, precision machinery, high-precision medical equipment and other industries.

[0003] When the existing drilling equipment is in use, the drill bit rotates continuously at a high speed, and the friction between the drill bit and the sheet metal is large, thereby generating a large amount of heat energy. During the cooling process, most equipment uses a nozzle set on one side of the drill bit to continuously spray coolant to the drill bit to achieve cooling of the drill bit. However, this method has the problem that when the coolant sprayed by the nozzle hits the drill bit, the coolant splashes everywhere due to the rotating movement of the drill bit, resulting in low cooling efficiency of the coolant. In addition, since the coolant only flows through quickly and does not have enough time to penetrate into the interior of the cutting area, for some deep holes or workpieces with complex internal structures, it may not be able to fully cool the bottom of the hole or the internal corners. When drilling deep holes, as the drilling depth increases, the cooling effect of the coolant at the bottom will gradually weaken. How to invent a five-axis linkage processing equipment with high-speed drilling to solve these problems has become an urgent problem to be solved by technical personnel in this field.

[0018] The beneficial effects of the present invention are:

[0019] 1. During the drilling process of sheet metal parts, since the initial drilling feed speed is relatively slow, the coolant can flow downward from the opening of the fixed seat to the surface of the drill bit to cool the drilling position. At the same time, the fan is started to blow the inhaled air through the exhaust slot to the surface of the sheet metal part, and the airflow can generate a cylindrical airflow barrier around the drill bit. The airflow barrier can intercept and block part of the coolant on the surface of the sheet metal part, slowing down the flow and diffusion speed of the coolant, so that the coolant can stay in the cutting area for a short time, and has more time to penetrate into the deep part and internal structure of the drill hole, thereby more effectively reducing the temperature of the entire drilling area, which is conducive to more even heat dissipation, so as to improve the drilling accuracy and workpiece quality, and improve the cooling efficiency of the coolant.

[0020] 2. As the drilling depth increases, the drilling speed will increase. At this time, the centrifugal force when the movable frame rotates is greater than the elastic force of the telescopic spring. The telescopic rod will drive the magnetic block to move to the inner wall of the fixed seat and stretch the telescopic spring. The telescopic airbag is compressed through the interaction between the magnetic block and the magnetic ring, and the gas inside it enters the interior of the fixed frame through the connecting pipe, expanding the expanded airbag, thereby reducing the size of the vent of the exhaust slot and changing the flow direction of the gas, so that the gas is blown to the end position of the drill bit. The air intake of the fan is constant, so the air flow velocity discharged from the exhaust slot increases at this time. As the gas flow rate increases, the force of the gas rushing out will also increase, thereby accelerating the chip removal efficiency and avoiding the problem that the drill bit generates waste chips too quickly when accelerating drilling, and fails to clean them up quickly and in time, resulting in waste chips mixed in the hole seam, causing obstacles to drilling. In addition, the coolant is used to form a dual cooling effect of air cooling and water cooling on the drilling position, and promotes the coolant to enter the inside of the drill hole to improve the cooling efficiency.

[0038] Fixing and adjusting of sheet metal parts by the overall equipment: When processing sheet metal parts, the sheet metal parts are first fixed by the processing table 10, and the positioning mechanism on the processing table 10 belongs to the prior art, so the specific installation method is no longer described in detail, and then the electric slide 32 can be controlled to slide on the slide rail 31 according to the drilling point on the surface of the sheet metal part to change the horizontal position of the support seat 41, thereby controlling the feed position of the drill bit 9 in the X-axis direction, and then the electric slide 42 can be used to control the movement of the slide rail 53, thereby changing the front and rear position of the rear seat 52, so as to control the feed position of the drill bit 9 in the Y-axis direction.

Moreover, the slide rails and the electric slide are also existing technologies, so the specific working process is not described in detail.

[0039] Reference Figure 4-Figure 10 , further; the support assembly 6 includes a support column 61 and a slide rail three 62, one side of the support column 61 is fixedly connected to the slide rail three 62, the slide rail three 62 is slidably connected to the electric skateboard three 51, a liquid storage chamber 63 is provided inside the support column 61, a motor 64 and a water pump 65 are provided inside the liquid storage chamber 63, a mounting seat 641 is rotatably connected inside the support column 61, one end of the mounting seat 641 is fixedly connected to the motor 64, a drain pipe 651 is provided inside the support column 61, one end of the drain pipe 651 is fixedly connected to the water pump 65, the mounting seat 641 is detachably connected to the drill bit 9, and a card slot 91 is provided on the outer wall of the drill bit 9.

[0040] Storage of coolant by the support column 61: A large amount of coolant can be installed inside the support column 61 through the liquid storage chamber 63, and a protective shell can be installed outside the motor 64 and the water pump 65 to avoid the influence of the coolant. During use, the mounting seat 641 can be driven to rotate by the motor 64, thereby driving the drill bit 9 to work. At the same time, the water pump 65 is started to transport the coolant to the inside of the fixed seat 73 through the drain pipe 651, so as to provide assistance for subsequent cooling. The mounting seat 641 and the drill bit 9 are detachably connected to facilitate the replacement of drill bits 9 of different sizes or damage.

[0041] Furthermore, the drilling assembly 7 includes a sleeve 71 and a fixed seat 73, the fixed seat 73 is fixedly connected to the lower end of the support column 61, the sleeve 71 is fixedly connected to the outer wall of the fixed seat 73, the upper end of the sleeve 71 is provided with a docking hole 733 adapted to the drain pipe 651, the side wall of the fixed seat 73 is provided with an exhaust slot 732, the inner wall of the exhaust slot 732 is provided with a plurality of through holes 731 distributed in a circumferential array, the side wall of the sleeve 71 is provided with an air inlet hole 72, the interior of the sleeve 71 is provided with a fan 74, and the fan 74 is fixedly connected to the outer wall of the fixed seat 73; the drilling assembly 7 also includes a limiting mechanism 76, the limiting mechanism 76 includes a limiting ring 761 and a connecting rod 762, the limiting ring 761 and the fixed seat 73 The movable frame 763 is provided with a telescopic rod 765 and a telescopic spring 766 inside, and the telescopic rod 765 is arranged in a "T" shape, and the telescopic rod 765 is slidably connected to the inner wall of the movable frame 763. The two ends of the telescopic spring 766 are respectively fixedly connected to the side wall of the telescopic rod 765 and the inner wall of the movable frame 763. The end of the telescopic rod 765 located on the outside of the movable frame 763 is fixedly connected to the magnetic block 764, and the movable frame 763 is slidably connected to the card slot 91.

[0042] The improvement of the cooling effect of the drilling component 7: during the installation of the drill bit 9 and the mounting seat 641, one end of the movable frame 763 can be connected to the inner wall of the slot 91. Through the limit connection between the two, the stability of the drill bit 9 during rotation can be increased, and the shaking can be reduced to improve the drilling accuracy. In the process of drilling the same sheet metal, first, at the beginning of drilling, the drill bit 9 needs to be accurately centered on the surface of the sheet metal. In order to avoid the drill bit 9 deviating from the predetermined position due to slight vibration or unbalanced cutting force when it quickly contacts the surface, a lower rotation speed and feed speed are generally used in this stage to ensure that the drill bit 9 can accurately start drilling at the predetermined position. In the initial drilling process, since the feed speed is relatively slow, the centrifugal force generated when the drill bit 9 drives the movable frame 763 to rotate is less than the elastic force of the telescopic spring 766. At this time, the magnetic block 764 fits against the side wall of the movable frame 763, and the coolant can be cooled from The opening of the fixing seat 73 flows downward to the surface of the drill bit 9, thereby cooling the position of the drilling hole. At the same time, the fan 74 is started to generate negative pressure inside the sleeve 71, and the outside air is sucked into the inside of the sleeve 71 through the air inlet 72. The sucked air is then quickly flowed to the inside of the exhaust slot 732 through the through hole 731, and then blown to the surface of the sheet metal. The surface coolant is thrown out through the rotation of the drill bit 9 itself, and the thrown coolant will splash in the direction of the wind flow. At the same time, the gas discharged from the exhaust slot 732 will flow in a staggered or vertical direction in the direction where the coolant splashes, and a cylindrical airflow barrier can be generated around the drill bit 9. The airflow barrier will block the splashed or fallen coolant. When the speed of the fan 74 is constant and the drilling speed is relatively slow, the power of the coolant when it is thrown out by centrifugal force is less than the air resistance, so that the coolant is not easily thrown out, effectively reducing the temperature of the air in the drilling area, and as Fig.10 As shown, the airflow barrier can intercept and block part of the coolant on the surface of the sheet metal, slowing down the flow and diffusion speed of the coolant, so that the coolant can stay in the cutting area for a short time and have more time to penetrate into the deep part and internal structure of the drilled hole, thereby more effectively reducing the temperature of the entire drilling area, and the coolant that stays for a short time can form a relatively stable cooling environment around the drilled hole, so that heat can be dissipated more evenly in all directions. This uniform cooling helps to reduce thermal deformation caused by temperature gradients, improve drilling accuracy and workpiece quality, and improve the cooling efficiency of the coolant. In the process of coolant flushing flow, waste chips can be quickly discharged through the airflow to avoid the accumulation of debris affecting the processing quality.

[0043] Furthermore, the drilling assembly 7 also includes an adjusting mechanism 75, which includes a fixed frame 754, which is fixedly connected to the inner wall of the fixed seat 73, and the side wall of the fixed frame 754 is fixedly connected with an expansion airbag 755, and the expansion airbag 755 is located on the inner side of the exhaust slot 732. The upper end of the fixed frame 754 is fixedly connected with a plurality of connecting tubes 753 distributed in a circular array, and the end of the connecting tube 753 away from the fixed frame 754 is provided with a telescopic airbag 751, and the upper end of the telescopic airbag 751 is fixedly connected with a magnetic ring 752.

[0044] The adjustment mechanism 75 improves the chip removal speed during drilling: During the drilling process of the same sheet metal, as the drilling depth increases, when the drill bit 9 successfully cuts into the sheet metal and reaches a certain depth, if the sheet metal material is uniform, the drilling speed can be appropriately increased at this time, because at this stage, the drill bit 9 has been stably cutting inside the material, and the cutting force is relatively stable. As long as it is within a reasonable range that the drill bit 9 and the equipment can withstand, increasing the speed can effectively improve the drilling efficiency. Therefore, as the drilling speed increases, the movable frame 763 The centrifugal force during rotation is greater than the elastic force of the telescopic spring 766. At this time, the telescopic rod 765 drives the magnetic block 764 to move toward the inner wall of the fixed seat 73 and stretch the telescopic spring 766, so that the magnetic block 764 is finally located above the magnetic ring 752. The polarity of the lower end of the magnetic block 764 is the same as the polarity of the upper end of the magnetic ring 752. Therefore, the telescopic airbag 751 is compressed at this time, and the gas inside it enters the interior of the fixed frame 754 through the connecting pipe 753. In the initial state, the expansion airbag 755 is in a contracted state, and the fixed frame 754 is in a closed state. 54 is connected to the expansion airbag 755, so the squeezed gas can make the expansion airbag 755 expand and expand, thereby reducing the size of the vent hole of the exhaust slot 732 and changing the flow direction of the gas, so that the gas is blown to the end position of the drill bit 9, and the air intake of the fan 74 is constant, so at this time, the air flow speed discharged from the exhaust slot 732 increases, and as the gas flow rate increases, the force of the gas rushing out will also increase, thereby accelerating the efficiency of chip removal, avoiding the drill bit 9 from generating waste chips too quickly when accelerating drilling, and failing to remove them in time. The cooling device is used to clean the holes quickly, thereby preventing waste chips from being mixed in the holes and hindering the drilling process. The cooling liquid is used in combination with the cooling liquid to form a dual cooling effect of air cooling and water cooling on the drilling position to improve the cooling efficiency. In addition, the outer diameter of the telescopic airbag 751 is smaller than the inner diameter of the fixed seat 73. When the telescopic rod 765 is extended, the coolant can also flow out smoothly from the gap between the telescopic airbag 751 and the fixed seat 73 to ensure the cooling effect. This equipment is suitable for the processing of three-dimensional flat sheet metal parts, and the drilling assembly 7 and the drill bit 9 can be replaced according to the size of the sheet metal parts.

[0045] Example 2, refer to Figure 3-Figure 6, further; the buffer assembly 8 includes a vertical cylinder 81 and a vertical rod 82, a plurality of vertical cylinders 81 are provided, and the plurality of vertical cylinders 81 are distributed in a circular array about the central axis of the sleeve 71, the vertical cylinder 81 is fixedly connected to the side wall of the sleeve 71, a buffer spring 811 is provided inside the vertical cylinder 81, the vertical rod 82 is slidably connected to the inner wall of the vertical cylinder 81, the vertical rod 82 is arranged in a "T" shape, and the two ends of the buffer spring 811 are respectively fixedly connected to the side wall of the vertical rod 82 and the inner wall of the vertical cylinder 81, and the end of the vertical rod 82 located on the outside of the vertical cylinder 81 is fixedly connected to an anti-slip pad 83.

[0046] The buffer component 8 strengthens the stability of the sheet metal position during drilling: after the sheet metal is fixedly mounted on the surface of the processing table 10, the drilling position of the drill bit 9 is adjusted, and then in the process of controlling the drill bit 9 to move downward, since the position of the anti-skid pad 83 is lower than the end of the drill bit 9, the anti-skid pad 83 will first contact the surface of the sheet metal. As the drilling component 7 continues to move downward, the interaction force between the sheet metal and the anti-skid pad 83 causes the vertical rod 82 to slide upward inside the vertical tube 81 and stretch the buffer spring 811. The anti-skid pad 83 can be made of rubber material, which is not only wear-resistant and non-slip, but also has certain high temperature resistance. Therefore, the buffer component 8 can increase the firmness of the sheet metal position before drilling, thereby effectively preventing the sheet metal from moving or deflecting during the drilling process, effectively ensuring the stability of the sheet metal, and preventing its deflection from affecting the normal operation of drilling.

[0047] It should be noted that the specific models and specifications of the motor, water pump and fan need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
