[0034] It should be noted that the hydraulic cylinder 203 is an execution element in the hydraulic system, which realizes the telescopic function through cooperation with the hydraulic system, and realizes the precise control of the telescopic displacement of the hydraulic cylinder piston rod through cooperation with the magnetic switch, proximity switch or photoelectric switch. Those skilled in the art can set it according to actual needs; The linear motor 204 adopts electromagnetic driving mode, realizes linear motion through electromagnetic action between stator and mover, can accurately drive the moving frame 201 to move along the preset track to ensure the position switching precision of the fin main body 6 between different processing steps.
[0035] In order to position and fix the position of the fin main body 6; The limiting component includes at least two positioning columns 212 fixed on the top of the placement table 207, and the positioning columns 212 pass through the fixing holes 7 on the fin main body 6. The circumferential outside of the positioning column 212 is provided with a sliding groove 218, and two symmetrical trapezoidal blocks 219 are slidably connected in the sliding groove 218. The fin main body 6 is clamped and fixed by the trapezoidal blocks 219 and the placement table 207. A spring 220 is arranged between the two trapezoidal blocks 219. The top of the positioning column 212 is provided with a pushing component for driving the two trapezoidal blocks 219 to move into the sliding groove 218. The pushing component includes a sliding hole formed in the top of the positioning column 212, a connecting frame 223 slidably connected in the sliding hole, and a connecting plate 221 rotatably connected to the bottom of the connecting frame 223. The two connecting plates 221 are rotatably connected with the trapezoidal blocks 219 respectively. The bottom of the sliding groove 218 is provided with an avoidance groove 222 for avoiding the connecting plate 221 and the connecting frame 223; When the fin main body 6 is placed on the placement table 207, the fixing hole 7 needs to be aligned with the positioning column 212 and pressed downward, and the connecting frame 223 is pressed downward at the same time. The connecting frame 223 drives the two trapezoidal blocks 219 to overcome the elastic force of the spring 220 and shrink into the sliding groove 218 through the connecting plate 221, so that the two trapezoidal blocks 219 are completely located in the sliding groove 218; The two trapezoidal blocks 219 slide inward along the sliding groove 218, which compresses the spring 220. When the fin main body 6 completely adheres to the top of the placement table 207, the connecting frame 223 is released. At this time, the spring 220 releases the elastic potential energy and pushes the two trapezoidal blocks 219 to reset outward, and the top surface thereof tightly abuts against the top of the fin main body 6, which realizes the up-down clamping and fixing of the fin main body 6 together with the placement table 207; When the finished fin body 6 needs to be removed, press down the connecting frame 223, the connecting frame 223 drives the two trapezoidal blocks 219 to overcome the elastic force of the springs 220 and retract into the sliding groove 218, thereby releasing the top limiting of the fin body 6, so that it can be easily removed from the positioning column 212; The avoidance slot 222 provides sufficient space for the movement of the connecting plate 221 and the connecting frame 223, avoiding structural interference during the sliding of the trapezoidal block 219, and ensuring the stable operation of the limiting assembly; The preliminary positioning is achieved by the cooperation of the positioning column 212 and the fixed hole 7 on the fin body 6, and the quick clamping and releasing is completed by the elastic expansion of the trapezoidal block 219. The entire operation process can be completed by pressing and releasing the connecting frame 223 without the need for additional tools, greatly simplifying the clamping process, while ensuring the positional stability of the fin body 6 during processing, effectively preventing cutting deviation caused by workpiece loosening.
[0036] In order to drive the placement table 207 to adjust the angle; The drive assembly includes a servo motor 211 fixed on one side of the sliding frame 202, the output shaft of the servo motor 211 is key connected with a first pulley 215, the rotating shaft of the placement table 207 is key connected with a second pulley 216 through the sliding frame 202, the second pulley 216 and the first pulley 215 are driven by a belt, and the bottom of the sliding frame 202 is fixed with a closed box 214, and the first pulley 215 and the second pulley 216 are located in the closed box 214, wherein the first pulley 215 and the second pulley 216 are synchronous pulleys, and are driven by a synchronous belt; When the cutting angle of the fin body 6 needs to be adjusted, the servo motor 211 starts according to the preset program, its output shaft drives the first pulley 215 to rotate, the first pulley 215 accurately transmits power to the second pulley 216 through the synchronous belt, and since the second pulley 216 is key connected with the rotating shaft of the placement table 207, the placement table 207 rotates synchronously with the second pulley 216, thereby driving the fin body 6 fixed on the placement table 207 to deflect at an angle; By utilizing the high-precision control characteristics of the servo motor 211 and combining the non-slip transmission advantages of the synchronous pulley and the synchronous belt, the rotation angle of the placement table 207 can be accurately controlled, meeting the processing needs of different cutting angles of the fin body 6; In addition, compared with the traditional gear transmission or chain transmission, the transmission mode of the synchronous pulley and the synchronous belt has the advantages of smooth transmission, no slip, low noise, easy maintenance, etc., which can effectively avoid impact and vibration during angle adjustment, further ensuring the stability and precision of angle adjustment; The arrangement of the closed box 214 isolates the transmission components such as the first pulley 215, the second pulley 216 and the synchronous belt from the external environment, preventing impurities such as aluminum chips and dust generated during the cutting process from entering the inside of the transmission system, avoiding problems such as transmission jamming and accelerated wear caused by impurities, prolonging the service life of the drive assembly and ensuring its long-term stable operation.
[0037] It should be noted that the servo motor 211 is used in cooperation with the encoder, and the number of rotations and the rotation angle are controllable, and its structure and principle are well known to those skilled in the art, and will not be described in detail here.
[0038] In order to fix the angle adjustment of the placement table 207; The locking assembly includes an electric push rod 205 fixed on one side of the sliding frame 202, and the movable end of the electric push rod 205 passes through the sliding frame 202 and is fixed by a bolt to the top frame 206 which is slidingly connected to the sliding frame 202. One end of the top frame 206 is welded with a top plate 213, and the top plate 213 is in contact with the angle-adjusted placement table 207; When the angle adjustment of the placement table 207 is completed, the electric push rod 205 is started, and its movable end pushes the top frame 206 to slide horizontally along the inner wall of the sliding frame 202, and the top frame 206 drives the top plate 213 to move synchronously until the side of the top plate 213 tightly abuts against the outer wall of the placement table 207; At this time, the top plate 213 exerts a lateral clamping force on the placement table 207, and through the combined action of friction and structural rigidity, the placement table 207 is firmly locked at the current adjusted angle position, preventing any slight rotation or displacement of the placement table 207 due to cutting force during the angle cutting operation of the cutting module 3; When the angle cutting operation is completed and the next angle adjustment is needed, the movable end of the electric push rod 205 is retracted, driving the top frame 206 and the top plate 213 away from the placement table 207 to release the locking state, so that the drive assembly can again drive the placement table 207 to rotate to a new preset angle; This locking method is fast in response, reliable in locking, simple in structure, easy to maintain, can accurately cooperate with the action of the drive assembly, and realizes the automatic switching of the angle adjustment and locking of the placement table 207.
[0039] It should be noted that the electric push rod 205 adopts a DC electric push rod with a model number of LAP22, which is used in cooperation with a magnetic switch, a proximity switch or a photoelectric switch to realize precise control of the extension and retraction displacement of the push rod, and can provide sufficient locking force to ensure that the placement table 207 remains angle-fixed during the entire cutting process, thereby ensuring the accuracy of the angle cutting size.
[0040] In order to keep the waste away from the sliding frame 202; The blowing assembly comprises a first external pipe 208 fixed at the bottom of the sliding frame 202 and a second external pipe 210 fixed at one side of the sliding frame 202, both of which are connected with an external air pump, and one end of each of the first external pipe 208 and the second external pipe 210 is fixed with an air jet head 209 through a nut, and the blowing mouth of the air jet head 209 is inclinedly arranged; When the cutting module 3 performs the corner cutting operation on the heat sink body 6, the external air pump is started, and the compressed air is delivered to the corresponding air jet head 209 through the first external pipe 208 and the second external pipe 210, and the inclined blowing mouth of the air jet head 209 sprays the compressed air at a certain angle to the cutting area and the edge of the sliding frame 202; Among them, the air jet head 209 connected with the first external pipe 208 blows the area near the avoidance opening 217 at the bottom of the placement table 207, and when the waste is separated from the heat sink body 6, the waste is directly blown to the direction of the material discharging module 4; The air jet head 209 connected with the second external pipe 210 blows from the side of the sliding frame 202 to the center axis side of the rotating shaft of the placement table 207, and when the heat sink body 6 is removed, the waste is blown to the middle and moved to the material discharging module 4; Through multi-directional and multi-angle airflow blowing, the waste scattering range around the cutting area can be fully covered, and it is ensured that the aluminum scraps and other wastes will not accumulate on the bottom of the sliding frame 202, the edge of the placement table 207 or the placement platform of the frame body 1; The inclined blowing mouth design makes the impact force of the compressed air more concentrated, which can effectively blow away the small waste adhering to the surface of the heat sink body 6 or the cutting tool.
[0041] In order to perform the corner cutting operation on the heat sink body 6; The cutting module 3 comprises a mounting frame 302 sliding on the frame body 1, one side of the mounting frame 302 is fixed with a cutting machine 303 through bolts, one side of the frame body 1 is fixed with a ball screw module 301 through bolts, and the sliding block of the ball screw module 301 is fixed with the mounting frame 302; When the heat sink body 6 needs to be corner cut, the ball screw module 301 starts according to the preset cutting path, and the sliding block drives the mounting frame 302 to move along the guide rail on the frame body 1, and the cutting machine 303 on the mounting frame 302 moves synchronously with the mounting frame 302; At the same time, the saw blade of the cutting machine 303 rotates at high speed to perform the corner cutting operation on the heat sink body 6 which has been adjusted in angle and fixed on the lower placement table 207; The ball screw module 301 controls the movement of the mounting frame 302, and in combination with the high-speed rotation of the saw blade of the cutting machine 303, realizes the cutting corner operation on the heat dissipation fin body 6, ensures that the cutting corner size is highly consistent with the preset parameters, guarantees the flatness and smoothness of the cutout, and provides a good structural basis for the subsequent assembly and use of the heat dissipation fin body 6.
