[0030] S1. Stacking: Stack the target workpiece to be processed inside the silo formed by the limit frame, the trough and the frame, and support it with an L-shaped plate that extends to the bottom of the silo under the action of spring 1, waiting for the material to fall;

[0031] S2, loading: control the servo motor to drive the turntable to rotate, use the straight bar that swings with the rotation of the turntable to push the longitudinal slide seat to approach the seat block, and use the material guide plate on the transverse slide seat that moves synchronously with the longitudinal slide seat to push the L-shaped plate out of the silo, so that the material at the bottom of the silo falls and is covered on the clamping column;

[0032] S3, clamping and centering: control motor 2 to drive the vertical axis to rotate, use the rotating gear to drive the two racks to move towards each other, drive the two side plates to move towards each other, and let the two centering screws limit the two sides of the target workpiece. At the same time, the rotation of the gear will also drive the straight rod to slide in the limiting groove, and use the sliding straight rod to drive the moving ring to rotate, so that the rotating moving ring pushes the end of the chuck away from the moving ring out of the through groove, and limits the upper side of the target workpiece;

[0033] S4, slotting: After the target workpiece that has been clamped and centered is reset with the longitudinal slide, the motor 1 is used to drive the screw to rotate, so that the transverse slide moves from the loading station to the slotting station, and in the process of pushing the longitudinal slide to approach the seat block, the end of the target workpiece to be processed is extended into the cavity surrounded by the fixed cylinder and the movable cylinder, and the target workpiece is slotted by the rotating saw blade;

[0034] S5, grinding: After the slotted target workpiece is reset with the longitudinal slide, the motor 1 is used to drive the screw to rotate, so that the transverse slide moves from the slotting station to the grinding station, and in the process of pushing the longitudinal slide to approach the seat block, the slotted end of the target workpiece enters the grinding area, and the inner side of the slot on the target workpiece is polished by the driven grinding belt;

[0035] S6. Unloading: After the target workpiece that has been polished is reset with the longitudinal slide, the motor is used to drive the screw to rotate, so that the transverse slide moves from the polishing station to the unloading station, and then the longitudinal slide continues to move in the reset direction. The end of the folding plate away from the transverse slide is swung downward under the guidance of the L-shaped guide frame, driving the other end of the folding plate to tilt upward, and after supporting the target workpiece to separate from the clamping column, the target workpiece automatically slides down and falls to the collection station under the guidance of the guide inclined plate.

[0036] Beneficial effects of the present invention:

[0037] 1. The present invention drives two racks to move toward each other by using rotating gears, so that two side plates move toward each other, and uses centering screws installed on the side plates to limit the two sides of the target workpiece. At the same time, the rotation of the gears also drives the straight rod to slide in the limiting groove, and uses the sliding straight rod to drive the moving ring to rotate, so that the rotating moving ring pushes one end of the chuck away from the moving ring out of the through groove, limits the upper side of the target workpiece, and avoids the target workpiece from swinging and jumping during the processing;

[0038] 2. The present invention utilizes the longitudinal feeding action of the feeding mechanism to push the target workpiece in and out of each processing station, and uses the lateral feeding action of the feeding mechanism to push the target workpiece to automatically flow between the loading, grooving, grinding and unloading stations. At the same time, multiple groups of clamping and centering mechanisms are arranged at equal intervals, so that multiple points can synchronously perform the actions of the corresponding stations, thereby improving production efficiency;

[0039] 3. The present invention uses spring 2 to push the stopper at the corresponding position out of the T-slot along the round rod, and uses the protruding stopper to prevent the locking nut from loosening during the slotting process, thereby affecting the processing accuracy.

[0079] Specifically, Figure 3 As shown, the feeding mechanism 3 includes a seat block 31 fixed on the mounting seat 2, a material groove 32 and a receiving groove 33 are opened on one side of the seat block 31, and the material groove 32 is connected with the receiving groove 33, wherein the arrangement of the receiving groove 33 can prevent the longitudinal sliding seat 73 and the transverse sliding seat 75 from being blocked during the longitudinal feeding and transverse feeding, a limiting frame 38 is fixedly provided at the position of the material groove 32 on the outer side of the seat block 31, and a material frame 34 is fixedly provided at the position of the material groove 32 on the top of the seat block 31;

[0080] An L-shaped plate 35 is movably provided at a position corresponding to the connection between the material trough 32 and the receiving groove 33 on one side of the seat block 31, and a spring 36 is fixedly connected between the end of the L-shaped plate 35 away from the material trough 32 and the outer side of the seat block 31, wherein, when the spring 36 is in a natural state, the L-shaped plate 35 can block the target workpiece to be processed inside the silo from falling under the action of the spring 36, and a vertical plate 37 is fixedly provided at the bottom of one end of the L-shaped plate 35 close to the limit frame 38, and an embedding groove is opened at the position of the vertical plate 37 on the inner side of the receiving groove 33 corresponding to the position of the vertical plate 37, wherein the setting of the embedding groove can make it possible to use the material guide support plate 13 to push the vertical plate 37 to drive the L-shaped plate 35 to release the blocking state of the bottom end of the silo without obstruction.

[0081] It should be noted that in the process of automatically loading the target component to be processed, the servo motor drives the turntable 711 to rotate, and the straight bar 713 that swings with the rotation of the turntable 711 is used to push the longitudinal slide seat 73 to approach the seat block 31. In the process of the longitudinal slide seat 73 driving the transverse slide seat 75 to gradually approach the seat block 31, the guide plate 13 on the transverse slide seat 75 will continue to push the vertical plate 37 to move away from the transverse slide seat 75 after contacting the vertical plate 37, thereby driving the L-shaped plate 35 to move synchronously in the direction away from the transverse slide seat 75 and stretching the spring 1 36, so that the L-shaped plate 35 gradually releases the blocking state of the bottom of the silo, allowing the target workpiece at the bottom of the silo to leave the silo under the action of its own gravity and be sleeved to the outside of the corresponding clamping column 814;

[0082] When the target workpiece at the bottom of the silo is separated from the silo sleeve to the outside of the corresponding clamping column 814 under the action of its own gravity, the longitudinal slide seat 73 will drive the transverse slide seat 75 to retreat synchronously, and the L-shaped plate 35 will seal the bottom of the silo again under the tensile restoring force of spring 1 36, waiting for the next round of material dropping.

[0083] Specifically, Figure 2 As shown, the driving assembly 4 includes a transverse shaft 42 which is rotatably installed on the seat block 31 and a bracket 41 which is fixed on the inner side of the frame 1. A motor 44 is fixedly installed on the top of the bracket 41. A driving wheel 43 is fixedly provided on the output shaft end of the motor 44 and one end of the transverse shaft 42. The two driving wheels 43 are connected by a belt drive.

[0084] It should be noted that during the operation of the driving assembly 4, the driving wheel 43 at the end of its output shaft is driven to rotate by the motor 44, and the driving wheel 43 at the end of the horizontal shaft 42 is driven to rotate synchronously by a belt, so that the horizontal shaft 42 rotates.

[0085] Specifically, Figure 3 and Figure 13-14As shown, the slotting mechanism 5 includes a fixed cylinder 51 movably sleeved on the outer side of the horizontal axis 42 and a mounting plate 53 fixedly sleeved on the outer side of the horizontal axis 42, a connecting rod 52 is fixedly connected between the fixed cylinder 51 and the seat block 31, a saw blade 54 is installed on the mounting plate 53, a locking nut is threadedly sleeved on the outer side of the horizontal axis 42, and an anti-loosening component 56 is provided at one end of the horizontal axis 42, and a movable cylinder 55 is fixedly installed on one side of the fixed cylinder 51 through a locking bolt, wherein the inner ring areas of the fixed cylinder 51 and the movable cylinder 55 are both set as truncated cone structures, and the inner ring area end surface of the fixed cylinder 51 is in contact with the outer side of the mounting plate 53, and the inner ring area end surface of the movable cylinder 55 is in contact with the outer side of the saw blade 54, which can reduce debris and coolant residue in the subsequent processing process;

[0086] The slotting mechanism 5 further includes a strip plate 57 fixed on the top of the seat block 31 and a slot opening formed on the outer side of the fixed cylinder 51. A liquid supply pipe 58 is installed on the strip plate 57. A nozzle communicating with the liquid supply pipe 58 is fixedly installed at a position corresponding to the slot opening on the inner side of the fixed cylinder 51. The liquid outlet of the nozzle faces the contact area between the saw blade 54 and the target workpiece, so as to cool the saw blade 54 and the target workpiece and reduce damage to the saw blade 54 and the target workpiece. A discharge pipe 59 is provided at the bottom end of the fixed cylinder 51.

[0087] The anti-loosening component 56 includes a T-slot 561 provided on the end surface of the horizontal axis 42, a partition plate 562 is fixedly provided in the middle of the inner side of the T-slot 561, and blocks 563 are movably inserted at both ends of the interior of the T-slot 561, wherein the two ends of the two blocks 563 that are opposite to each other and away from the saw blade 54 are both provided with inclined surfaces, so that the corresponding block 563 can be retracted into the interior of the T-slot 561 without moving the dial plate 564 during the process of limiting the position of the saw blade 54 by using the locking nut, and the outer sides of the two blocks 563 are fixed A paddle plate 564 is provided that extends to the outer side of the T-slot 561, and round rods 565 that movably penetrate the corresponding paddle plates 564 are fixedly provided on both sides of the partition plate 562. Spring 2 566 that is fixedly connected to the partition plate 562 and the corresponding paddle plate 564 is sleeved on the outer sides of the two round rods 565. When the spring 2 566 is in a natural state, the opposite ends of the two stoppers 563 extend to the outside of the T-slot 561, but the paddle plates 564 on the stoppers 563 remain sleeved on the outer sides of the corresponding round rods 565.

[0088] It should be noted that, in the process of slotting the target workpiece after clamping and centering, when the target workpiece after clamping and centering is reset with the longitudinal slide seat 73, the control motor 1 710 drives the screw rod 78 to rotate, so that the transverse slide seat 75 moves from the loading station to the slotting station, and then in the process of pushing the longitudinal slide seat 73 to approach the seat block 31, the end of the target workpiece to be processed and the guide support plate 13 are extended into the cavity surrounded by the fixed cylinder 51 and the movable cylinder 55, and the saw blade 54 is driven by the rotating shaft 42 to rotate at a high speed to slot the target workpiece;

[0089] It should be further explained that the material guide support plate 13 enters the cavity formed between the fixed cylinder 51 and the movable cylinder 55 just before the target workpiece is released from the rotating saw blade 54 , that is, the target workpiece enters the cavity formed between the fixed cylinder 51 and the movable cylinder 55 first.

[0090] When the anti-loosening component 56 is used to prevent the locking nut that restricts the saw blade 54 from loosening, when the locking nut is twisted, it squeezes the block 563 and compresses the corresponding spring 2 566 during the screwing process. After the locking nut completely passes over the block 563, the opposite ends of the two blocks 563 will be pushed out of the T-slot 561 under the action of the restoring force of the corresponding spring 2 566, thereby utilizing the block 563 to prevent the locking nut from loosening during the slotting process.

[0091] Specifically, Fig.16 As shown, the grinding mechanism 9 includes two upright frames 91 fixed on the top of the mounting base 2, a collecting frame 92 is fixedly arranged between the tops of the two upright frames 91, a truss 95 is fixedly arranged on the inner side of the collecting frame 92, a grinding belt 96 and a motor 97 for driving the grinding belt 96 are installed on the truss 95, wherein the collecting frame 92 is arranged as a Y-shaped structure, which will not affect the target workpiece after grooving to be sent into the grinding area for polishing by the grinding belt 96, and can guide the metal dust generated by grinding to gather to the middle of the collecting frame 92, and a filter plate 93 and a fan 94 are fixedly arranged on the inner bottom end of the collecting frame 92 from top to bottom.

[0092] It should be noted that after the target workpiece that has completed slotting is reset with the longitudinal slide 73, the motor 710 continues to be controlled to drive the screw 78 to rotate, so that the transverse slide 75 moves from the slotting station to the grinding station, and then in the process of pushing the longitudinal slide 73 closer to the seat block 31, the slotted target workpiece is allowed to approach the grinding area. During this process, the end of the high-speed transmission grinding belt will extend into the slot on the target workpiece to polish the inner side of the slot on the target workpiece.

[0093] Specifically, Figure 5-6 and Fig.12 As shown, the unloading mechanism 6 includes two brackets 61 fixed on the top of the horizontal sliding seat 75, a rotating rod 63 is rotatably installed between the two brackets 61, and folding plates 64 are fixedly sleeved at both ends of the outer side of the rotating rod 63, and a through groove 65 is opened at one end of the two folding plates 64;

[0094] A groove 69 is provided at the top of the horizontal sliding seat 75 at a position corresponding to the end of the folding plate 64 away from the through slot 65, and a vertical rod 62 that movably penetrates the through slot 65 is fixed at the top of the horizontal sliding seat 75 at a position corresponding to the through slot 65. A spring three 66 that fixes the folding plate 64 and the horizontal sliding seat 75 is sleeved on the outer side of the vertical rod 62. When the spring three 66 is in a natural state, the end of the folding plate 64 close to the clamping column 814 is completely movably embedded in the corresponding groove 69. At the same time, the top of the vertical rod 62 still maintains a state of penetrating the inside of the through slot 65 (such as Fig.12 shown);

[0095] The unloading mechanism 6 further comprises an L-shaped guide frame 67 fixed on the top of the frame 1 , and a material guiding inclined plate 68 is fixed on the top of the L-shaped guide frame 67 .

[0096] It should be noted that after the target workpiece that has been polished is reset with the longitudinal slide 73, the motor 710 is continued to be controlled to drive the screw 78 to rotate, so that the transverse slide 75 is moved from the polishing station to the unloading station. At this time, the servo motor is controlled to drive the turntable 711 to continue to rotate counterclockwise, so that the longitudinal slide 73 drives the transverse slide 75 to approach the direction of the bracket 61, so that the end of the folding plate 64 close to the L-shaped guide frame 67 is guided by the inclined surface of the L-shaped guide frame 67 and swings downward, thereby driving the other end of the folding plate 64 to tilt upward, and support the finished target workpiece to separate from the clamping column 814, allowing the target workpiece to slide automatically and fall to the collection station under the guidance of the guide inclined plate 68.

[0097] Specifically, Fig.15 As shown, a recycling mechanism 10 is provided at a position on the top of the mounting seat 2 corresponding to the slotting mechanism 5, and the recycling mechanism 10 includes a collecting box 101 fixed on the top of the mounting seat 2, a filter frame 102 is provided on the inner side of the collecting box 101, and hanging grooves 103 with T-shaped structures are provided on both sides of the top surface of the collecting box 101, wherein the hanging groove 103 is set as a T-shaped structure, so that the filter frame 102 can be quickly hung on the collecting box 101 conveniently, and the two ends of the filter frame 102 are movably hung inside the hanging grooves 103 on the corresponding sides.

[0098] It should be noted that in the process of grooving the target workpiece using the high-speed rotating saw blade 54, the coolant mixed with waste chips will fall into the filter frame 102 inside the collection box 101 through the drain pipe 59, and the filter frame 102 will be used to separate the coolant from the waste chips. The filtered waste chips can be returned to the production line for melting and reuse, while the filtered coolant can be connected to a reflux pipe connected to the liquid supply pipe 58 on the outside of the collection box 101, and the coolant collected in the collection box 101 can be pumped out for recycling using a pump.

[0099] In the above technical scheme, the motor 1 710 and the motor 2 83 mentioned above both use the driving motor model JSDL2-10A1; the motor 1 44 and the motor 2 97 mentioned above both use the three-phase asynchronous motor model YD series; the servo motor mentioned above uses the commercially available servo motor model JSMA-PUC02D; the fan mentioned above uses the negative pressure fan model Lanhao 900.

[0101] S1. Stacking: Stack the target workpiece to be processed inside the material bin formed by the limit frame 38, the material trough 32 and the material frame 34, and support it with the L-shaped plate 35 extending to the bottom of the inner side of the material bin under the action of the spring 1 36, waiting for the material to fall;

[0102] S2, loading: control the servo motor to drive the turntable 711 to rotate, use the straight bar 713 that swings with the rotation of the turntable 711 to push the longitudinal slide 73 to approach the seat block 31, and use the material guide support plate 13 on the transverse slide 75 that moves synchronously with the longitudinal slide 73 to push the L-shaped plate 35 out of the silo, so that the material at the bottom of the silo falls and is covered on the clamping column 814;

[0103] S3, clamping and centering: control the second motor 83 to drive the vertical shaft 84 to rotate, and use the rotating gear 85 to drive the two racks 88 to move toward each other, drive the two side plates 811 to move toward each other, and let the two centering screws 813 limit the two sides of the target workpiece. At the same time, the rotation of the gear 85 will also drive the straight rod 86 to slide in the limiting groove 87, and use the sliding straight rod 86 to drive the moving ring 818 to rotate, so that the rotating moving ring 818 pushes the end of the clamping head 821 away from the moving ring 818 out of the through groove 819, and limits the upper side of the target workpiece;

[0104] S4, slotting: After the target workpiece is clamped and centered and reset with the longitudinal slide 73, the motor 1 710 is used to drive the screw 78 to rotate, so that the transverse slide 75 moves from the loading station to the slotting station, and in the process of pushing the longitudinal slide 73 to approach the seat block 31, the end of the target workpiece to be processed is extended into the cavity surrounded by the fixed cylinder 51 and the movable cylinder 55, and the target workpiece is slotted by the rotating saw blade 54;

[0105] S5, grinding: After the target workpiece with the slotted groove is reset with the longitudinal slide 73, the motor 1 710 is used to drive the screw 78 to rotate, so that the transverse slide 75 is moved from the slotting station to the grinding station, and in the process of pushing the longitudinal slide 73 to approach the seat block 31, the slotted end of the target workpiece is allowed to enter the grinding area, and the inner side of the slot on the target workpiece is polished by the driven grinding belt 96;

[0106] S6. Unloading: After the target workpiece that has been polished is reset with the longitudinal slide 73, the motor 710 is used to drive the screw 78 to rotate, so that the transverse slide 75 is moved from the polishing station to the unloading station, and then the longitudinal slide 73 is continued to move in the reset direction. The end of the folding plate 64 away from the transverse slide 75 is swung downward under the guidance of the L-shaped guide frame 67, driving the other end of the folding plate 64 to tilt upward, and after supporting the target workpiece to separate from the clamping column 814, the target workpiece automatically slides down and falls to the collection station under the guidance of the guide inclined plate 68.

10. A method for processing a lower outlet assembly of a vacuum circuit breaker, using the automatic processing equipment for the lower outlet assembly of a vacuum circuit breaker according to any one of claims 1 to 9 to process the lower outlet assembly of a vacuum circuit breaker, characterized in that: The specific steps include the following: S1, stacking materials: stacking the target workpiece to be processed inside the material bin formed by the limiting frame (38), the material trough (32) and the material frame (34), and holding it with an L-shaped plate (35) extending to the bottom of the inner side of the material bin under the action of a spring (36), waiting for the material to fall; S2, loading: controlling the servo motor to drive the turntable (711) to rotate, using the straight bar (713) that swings with the rotation of the turntable (711) to push the longitudinal slide seat (73) to approach the seat block (31), and using the material guide support plate (13) on the transverse slide seat (75) that moves synchronously with the longitudinal slide seat (73) to push the L-shaped plate (35) out of the silo, so that the material at the bottom of the silo falls and is sleeved on the clamping column (814); S3, clamping and centering: control motor 2 (83) to drive the vertical shaft (84) to rotate, and use the rotating gear (85) to drive the two racks (88) to move toward each other, drive the two side plates (811) to move toward each other, and allow the two centering screws (813) to limit the two sides of the target workpiece. At the same time, the rotation of the gear (85) will also drive the straight rod (86) to slide in the limiting groove (87), and use the sliding straight rod (86) to drive the moving ring (818) to rotate, so that the rotating moving ring (818) pushes the chuck (821) away from one end of the moving ring (818) out of the through groove (819), thereby limiting the upper side of the target workpiece; S4, slotting: after the target workpiece is clamped and centered and reset with the longitudinal slide seat (73), the motor 1 (710) is used to drive the screw rod (78) to rotate, so that the transverse slide seat (75) moves from the loading station to the slotting station, and in the process of pushing the longitudinal slide seat (73) closer to the seat block (31), the end of the target workpiece to be processed is extended into the cavity enclosed by the fixed cylinder (51) and the movable cylinder (55), and the target workpiece is slotted using the rotating saw blade (54); S5, grinding: after the target workpiece with the slotted surface is reset with the longitudinal slide seat (73), the motor 1 (710) is used to drive the screw rod (78) to rotate, so that the transverse slide seat (75) moves from the slotting station to the grinding station, and in the process of pushing the longitudinal slide seat (73) to approach the seat block (31), the slotted end of the target workpiece enters the grinding area, and the inner side of the slot on the target workpiece is polished by the driven grinding belt (96); S6, unloading: After the target workpiece that has been polished is reset with the longitudinal slide seat (73), the motor 1 (710) is used to drive the screw rod (78) to rotate, so that the transverse slide seat (75) moves from the polishing station to the unloading station, and then continues to push the longitudinal slide seat (73) to move in the reset direction, and the end of the folding plate (64) away from the transverse slide seat (75) is swung downward under the guidance of the L-shaped guide frame (67), driving the other end of the folding plate (64) to tilt upward, and after supporting the target workpiece to separate from the clamping column (814), the target workpiece automatically slides down and falls to the collection station under the guidance of the guide inclined plate (68).
