Technical Field

[0001] The invention relates to the technical field of assembly and manufacturing of circuit breakers, in particular to vacuum circuit breaker assembly equipment and a method thereof. Background Art

It has the advantages of small size, light weight, suitable for frequent operation, and arc extinguishing without maintenance. It is widely used in distribution networks. The vacuum circuit breaker can play a stable control and protection role on electrical equipment. The existing vacuum circuit breaker consists of two parts: the pole and the chassis operating mechanism. When the vacuum circuit breaker is produced, the assembled chassis and pole need to be assembled.

[0003] The prior art discloses a Chinese patent with publication number CN 113560838 A (IPC classification number B23P19 / 00): A vacuum circuit breaker assembly machine and assembly method, and discloses a bottom plate, a positioning device, an adjusting device and a clamping device, wherein the bottom plate is installed with an adjusting device, the bottom plate and the adjusting device are both installed with positioning devices, and the rear end of the bottom plate is installed with a clamping device. The positioning device and the adjusting device designed in the technical scheme perform a stable buffering and supporting operation on the pole through the lifting spring rod and the lifting circular plate in the positioning circular box, and drive the arc plate, the arc rod, the arc plate and the rubber block to position the outer wall of the pole through the positioning cylinder and the push plate, thereby improving the stability of the pole positioning and preventing the arc extinguishing chamber in the pole from being broken, and the sliding plate is driven to move by the adjusting cylinder, and the sliding plate can drive the pole positioned in the positioning circular box to move to a suitable assembly position, which provides convenience for the assembly operation of the pole.

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] A vacuum circuit breaker assembly device and method thereof are characterized by a machine for simply assembling metal parts or products for producing vacuum circuit breakers with non-metal parts, and the IPC classification number is B23P19 / 00.

[0047] Refer to the instruction manual Figure 1-3 , a vacuum circuit breaker assembly device and method according to an embodiment of the present invention comprises a frame 1, two brackets 2 arranged in parallel are arranged on the top of the frame 1, a crimping positioning mechanism 3 and a mechanism box feeding mechanism 4 are respectively arranged on the opposite sides of the two brackets 2 on the top of the frame 1, a pushing mechanism 5 is arranged between the two brackets 2, and a pole feeding mechanism 6 is arranged on one end of the top of the frame 1 between the two brackets 2;

[0048] The crimping positioning mechanism 3 is composed of a reciprocating swing assembly and a clamping assembly 39 , and a screw driving mechanism 7 is installed at one end between the top end surfaces of the two brackets 2 away from the pole feeding mechanism 6 .

[0049] It should be noted that the present invention utilizes the mechanism box loading mechanism 4 and the pole loading mechanism 6 to push the target mechanism box and the target pole to be assembled to the designated loading position respectively, and utilizes the reciprocating swing assembly to push the clamping assembly 39 to the pole loading position to clamp the target pole, and then the reciprocating swing assembly pushes the clamped target pole to the press-fitting station. At the same time, the pushing mechanism 5 is utilized to push the target mechanism box to the press-fitting station, and finally the action of the reciprocating swing assembly is utilized to complete the press-fitting work and push the screw driving mechanism to complete the screw driving action.

[0050] Specifically, Figure 1 and Figure 8-9 As shown, the mechanism box feeding mechanism 4 includes a material box 41 fixedly arranged on the outer side of the surface of the bracket 2 at the location and a slot 42 opened on the surface of the bracket 2 at the location, a cylinder 43 is fixedly arranged at the position corresponding to the slot 42 on the inner side of the material box 41, a push plate 44 is fixedly arranged at the telescopic end of the cylinder 43, a straight rod 45 is movably penetrated through the middle part of one end of the material box 41, a push plate 46 and a limit plate 47 are fixedly arranged at both ends of the straight rod 45, and a spring 48 is movably sleeved on the outer peripheral surface of one end of the straight rod 45 extending to the outside of the material box 41.

[0051] It should be noted that, in the initial state, the push plate 44 is completely retracted in the recessed area inside the material box 41. When loading the target mechanism box, it is necessary to pull the straight rod 45 outward in advance and stretch the spring 48, and then stack the target mechanism boxes in the material box 41 in sequence, and push the target mechanism box to the mechanism box loading position by the stretching recovery force of the spring 48. When the target mechanism box needs to be pushed from the loading position to the pushing position between the two brackets 2, the control end controls the cylinder 43 to push the push plate 44 to push the target mechanism box at the current loading position to the pushing position between the two brackets 2 through the notch 42, and then the target mechanism box at the current pushing position is pushed to the press-fitting position by the pushing mechanism 5;

[0052] After the push plate 44 completes the pushing and loading and returns to the initial position, the stretching and restoring force of the spring 48 will be used to push the next target mechanism box to the mechanism box loading position, waiting for the next round of pushing and loading.

[0053] Specifically, Figure 1 and Figure 9-12 As shown, the pushing mechanism 5 includes a support platform 51 fixedly arranged between the two brackets 2, a dovetail groove 52 is horizontally penetrated in the middle of the top surface of the support platform 51, a guide groove 57 is vertically penetrated in the middle of the bottom end surface of the inner cavity of the dovetail groove 52, a dovetail block 53 is slidably connected inside the dovetail groove 52, a slide 54 and a slide guide seat 56 are fixed on the top and bottom of the dovetail block 53, and the guide seat 56 is slidably connected inside the guide groove 57, and a plurality of pusher components 55 arranged equidistantly are installed in the middle of the top of the slide 54;

[0054] A mounting plate 58 is fixedly provided at one end of the bottom of the support platform 51 near the pole loading mechanism 6, and a strip plate 2 59 is provided on one side of the mounting plate 58. A swing plate 2 510 is rotatably installed at one end of the strip plate 2 59 away from the mounting plate 58 through a round rod, and the end of the swing plate 2 510 away from the strip plate 2 59 is hinged to the bottom end of the guide seat 56, and a driving motor 1 is fixedly installed at the bottom end of the mounting plate 58 away from the strip plate 2 59, and the output shaft end of the driving motor 1 movably passes through the mounting plate 58 and is fixedly connected to the strip plate 2 59. A supporting plate 511 is fixedly provided at the position corresponding to the notch 42 at the bottom end of the opposite sides of the two brackets 2, wherein the setting of the supporting plate 511 can effectively prevent the forward end of the target mechanism box from tilting due to the center of gravity problem during the process of pushing the target mechanism box from the mechanism box upper material position to the push material position, resulting in a failure in pushing;

[0055] Each pusher assembly 55 includes two seat blocks 551 fixed on the top of the slide 54, a rotating rod is rotatably installed between the two seat blocks 551 arranged opposite to each other, two baffles 553 are fixedly provided on the outer circumference of the rotating rod, and a spring 552 is fixedly connected between the bottom end face of one of the baffles 553 away from the rotating rod and the top end face of the slide 54.

[0056] It should be noted that the angle formed between the two baffles 553 on each pushing assembly 55 is 120°, and one of the baffles 553 is perpendicular to the upper surface of the slide 54, while the end of the other baffle 553 away from the rotating rod is in contact with the upper surface of the slide 54 under the action of the tensile restoring force of the spring 2 552; the distance between the opposite sides of the two support plates 511 is greater than the width of the baffle 553, ensuring that the pushing assembly 55 can smoothly push the target mechanism box from the pushing position to the pressing position.

[0057] In the process of pushing the target mechanism box from the pushing material position between the two brackets 2 to the press fitting station, the strip plate 2 59 is driven by the driving motor 1 to rotate in a circle, and the strip plate 2 59 that moves in a circle drives the swing plate 2 510 to swing up and down with the hinge point between the guide seat 56 as the center, and at the same time, pulls the slide 54 to perform reciprocating linear motion along the direction of the dovetail groove 52;

[0058] When the swinging swing plate 2 510 pulls the slide 54 to move to the right (refer to the attached manual Fig.11 When the slide 54 moves to the right, the push assembly 55 moves to the right synchronously. After the baffle 553 perpendicular to the upper surface of the slide 54 contacts the target mechanism box at the material pushing position, as the slide 54 continues to move to the right, the target mechanism box pushes the baffle 553 at the rightmost vertical state to swing to the left, and at the same time, drives another baffle 553 to tilt upward and stretch the spring 2 522 at the corresponding position. After the push assembly 55 at the rightmost end completely passes the target mechanism box at the material pushing position, the two baffles 553 on the push assembly 55 will quickly reset under the tensile restoring force of the spring 2 552;

[0059] When the swinging swing plate 2 510 pushes the slide 54 to move from the rightmost end to the left, the baffle 553 perpendicular to the upper surface of the slide 54 after resetting will move left with the slide 54, pushing the target mechanism box pressing station at the pushing position. After being pushed into place, the slide 54 moves to the right again to repeat the above pushing process.

[0060] Specifically, Figure 3 As shown, the pole feeding mechanism 6 includes two vertical plates 61 fixedly arranged on the top of the frame 1, and a conveyor belt 62 driven by a stepper motor is installed between the opposite sides of the two vertical plates 61. A plurality of groups of brackets 63 arranged equidistantly are fixedly arranged on the outer surface of the conveyor belt 62. Each group of brackets 63 is composed of two mounting strips located at the edge positions on both sides of the outer surface of the conveyor belt 62. A bearing plate 64 is rotatably installed between the two mounting strips arranged opposite to each other in each group through a round rod, and three counterweight inserts 65 are fixedly penetrated and embedded in the middle of the bottom of each bearing plate 64.

[0061] It should be noted that the provision of the counterweight insert 65 can ensure that the carrier plate 64 always remains in a horizontal state during the synchronous transmission process with the transmission belt 62. When loading the target pole, the pole to be assembled needs to be first inserted into the counterweight insert 65 on each carrier plate 64, and then during the assembly process, the conveyor belt 62 is intermittently driven by a stepper motor to transport it forward one workstation, thereby realizing the automatic supply of the target pole.

[0062] Specifically, Figure 1 and Figure 4-6 As shown, the reciprocating swing assembly includes a vertical plate 31 fixedly arranged on the top of the frame 1 and a driving motor 2 fixedly installed on the outer side of the bracket 2 at the position, two L-shaped bars 32 arranged horizontally and parallelly are fixedly arranged on the top of the vertical plate 31 facing the bracket 2, a T-shaped slider 33 is slidably connected inside the T-shaped groove formed by the two L-shaped bars 32, a straight bar 310 is fixedly arranged on the side of the T-shaped slider 33 facing the driving motor 2, a strip plate 1 311 is fixedly connected to the end of the output shaft of the driving motor 2, a swing plate 1 312 is rotatably installed on the end of the strip plate 1 311 away from the driving motor 2 through a round rod, and an end of the swing plate 1 312 away from the strip plate 1 311 is hinged to the straight bar 310;

[0063] A U-shaped through groove 34 is penetrated through one side of the vertical plate 31 at a position between the two L-shaped bars 32, and an inverted V-shaped groove 35 is penetrated through one side of the T-shaped slider 33. A sliding column 36 is slidably installed at the penetration of the U-shaped through groove 34 and the V-shaped groove 35. Limit plates 37 are fixedly provided at both ends of the two sliding columns 36, and the opposite sides of the two limit plates 37 are respectively fitted with the surfaces of the vertical plate 31 and the T-shaped slider 33. A cross plate 38 is fixedly provided on one side of the limit plate 37 fitted with the T-shaped slider 33, and a clamping assembly 39 is installed on the end of the cross plate 38 away from the limit plate 37.

[0064] It should be noted that, in the process of using the reciprocating swing assembly to push the clamping assembly 39 to the pole upper material position to clamp the target pole, and pushing it to the press-fitting station to complete the press-fitting of the target pole, the strip plate 1 311 is driven by the driving motor 2 to rotate in a circle, and the strip plate 1 311 that rotates in a circle drives the swing plate 1 312 to swing up and down with the hinge point between the strip and the straight strip 310 as the center, and at the same time, the T-shaped slider 33 is pulled to perform reciprocating linear motion along the direction of the T-shaped groove formed by the two L-shaped strips 32, so as to realize continuous material taking and press-fitting actions;

[0065] In the above-mentioned process of taking materials and pressing, when the swinging swing plate 1 312 pushes the T-shaped slide block 33 to move to the right (refer to the attached manual), Figure 4When the T-shaped slider 33 moves to the right, the slide post 36 will be driven to move to the right along the U-shaped slot 34 synchronously, and when the slide post 36 moves to the vertical section area at the right end of the U-shaped slot 34, as the T-shaped slider 33 continues to move to the right, the slide post 36 will drive the cross plate 38 to move down along the vertical section at the right end of the U-shaped slot 34, and at the same time, it will move obliquely downward along the left half of the V-shaped slot 35, so that the clamping assembly 39 is close to the target pole, and the clamping assembly 39 is used to clamp the target pole;

[0066] When the swinging swing plate 312 pushes the T-shaped slide block 33 to move from the rightmost end to the left, as the T-shaped slide block 33 moves to the left, the clamping assembly 39 that clamps the target pole will move up with the cross plate 38 and disengage from the counterweight insert 65, and will simultaneously perform a translational movement after the slide post 36 enters the horizontal section of the U-shaped through groove 34. When the slide post 36 enters the vertical section area at the left end of the U-shaped through groove 34, as the T-shaped slide block 33 continues to move to the left, the slide post 36 will drive the cross plate 38 to move down along the vertical section at the left end of the U-shaped through groove 34, and at the same time, it will move obliquely downward along the right half of the V-shaped groove 35, so that the clamping assembly 39 that clamps the target pole is close to the target mechanism box of the press-fitting station, and the target pole is press-fitted to the specified position on the target mechanism box. In this way, continuous target pole material removal and continuous press-fitting between the target pole and the target mechanism box can be realized.

[0067] Specifically, Figure 4-7 As shown, the clamping assembly 39 includes a through slot 391 vertically penetrating the horizontal plate 38, two partitions 392 are fixedly arranged inside the through slot 391, a shaft 393 is rotatably installed in the middle of the inner cavity of the through slot 391, and the shaft 393 movably penetrates the partition 392, and the two partitions 392 divide the inner cavity of the through slot 391 into three cavities, and two cross sliders 394 are slidably installed inside each cavity, each cross slider 394 is threadedly sleeved on the outside of the shaft 393, and a semi-cylinder 395 is fixedly arranged in the middle of the bottom of each cross slider 394;

[0068] An arc-shaped groove 397 is provided on the inner circumference of each semi-cylinder 395, and three sets of rubber rollers 396 are rotatably installed inside each arc-shaped groove 397. A servo motor is fixedly installed at the position of the rubber roller 396 at the middle position corresponding to the bottom of each semi-cylinder 395, and the output shaft end of the servo motor is fixedly connected to the rubber roller 396 at that position. A laser sensor 398 is fixedly installed at the position of each cavity corresponding to one side of the bottom end surface of the cross plate 38.

[0069] It should be noted that after the cross plate 38 moves to the press-fitting station, the laser emitting end of the laser sensor 398 is facing one of the mounting holes on the target mechanism box at the location, and the rubber roller 396 in the middle of the two semi-cylinders 395 on each set of clamping assemblies 39 rotates in the same direction to drive the target pole to rotate for position adjustment. In addition, the shaft rod 393 is rotated by a driving motor, and the outer circumference of the shaft rod 393 corresponding to each part of each cavity is tapped with two groups of oppositely arranged threads to ensure that when the shaft rod 393 rotates, it can drive the two cross sliders 394 inside each cavity to move synchronously toward or away from each other.

[0070] In the process of clamping the target pole by the clamping assembly 39, the control end controls the driving motor to drive the shaft 393 to rotate, so that the two cross slides 394 in each cavity move toward each other, and after the press fitting is completed, the driving shaft 393 rotates in the opposite direction, so that the two cross slides 394 in each cavity move away from each other, thereby releasing the clamping state of the target pole at the location;

[0071] After the clamping assembly 39 for clamping the target pole enters the press-fitting station with the cross plate 38, the laser sensor 398 will emit a laser beam, which will first pass through the mounting hole on the target pole. If the laser beam cannot synchronously pass through the mounting hole on the target pole and the mounting hole at the corresponding position on the target mechanism box, the mounting holes of the two are in a non-aligned state. At this time, after receiving the feedback signal from the laser sensor 398, the control end will control the servo motor to drive the rubber roller 396 at the corresponding position to rotate, thereby driving the clamped pole to rotate until the mounting hole on the target pole is aligned with the mounting hole at the corresponding position on the target mechanism box.

[0072] When the push mechanism 5 pushes the target mechanism box of the subsequent sequence into the press-fitting station, the left end of the slide 54 (refer to the attached manual) Fig.11 The pushing assembly 55 (in the direction of the material) will push the target pole and the target mechanism box that have been crimped in the previous sequence to the screw-driving station.

[0073] Specifically, Figure 4 and Figure 6 As shown, a T-shaped slot 313 is provided on the bottom end surface of the L-shaped bar 32 at the lower end, a slide seat 314 is slidably installed inside the T-shaped slot 313, and a guide column 315 is fixedly provided on the top end surface of the slide seat 314 extending to the outside of the T-shaped slot 313, and the top end of the guide column 315 movably passes through the horizontal plate 38.

[0074] It should be noted that the guide column 315 always remains in a movable state passing through the cross plate 38, wherein, when the slide column 36 moves along the U-shaped through groove 34, in order to prevent the clamping assembly 39 from shaking, the slide seat 314 can be slidably installed at the bottom end of the L-shaped bar 32 at the lower end, and the guide column 315 is allowed to pass through the cross plate 38 to ensure that the clamping assembly 39 can only move linearly with the cross plate 38. In this way, the target pole material removal and the press-fitting of the target pole and the target mechanism box can be ensured to proceed smoothly.

[0075] Specifically, Figure 1 and Fig.13 As shown, the screw driving mechanism 7 includes a U-shaped frame 71 fixedly mounted between the top ends of the two brackets 2 and a pressure plate 76 fixedly mounted on the surface of the side of the horizontal plate 38 facing the screw driving mechanism 7. A lifting plate 72 is arranged on the top of the U-shaped frame 71. Cylinders 73 are fixedly mounted at the four corners of the top end of the U-shaped frame 71, and the top ends of the four cylinders 73 are movably penetrated through the lifting plate 72. A spring three 74 is movably sleeved on the outer circumference of each cylinder 73, and the two ends of the spring three 74 are respectively fixedly connected to the U-shaped frame 71 and the lifting plate 72. A plurality of screw driving machines 75 are fixedly mounted at the bottom of the lifting plate 72, and the screw driving end of each screw driving machine 75 is movably penetrated through the U-shaped frame 71. A channel groove is penetrated at the position of the pressure plate 76 on one side of the lifting plate 72.

[0076] It should be noted that the cylinder 73 always remains in a state of being movable and passing through the lifting plate 72, and when the press-fitting action is performed, the end of the pressing plate 76 away from the cross plate 38 is movable and passed through the channel groove on the lifting plate 72, and when the target pole is taken out, the end of the pressing plate 76 away from the cross plate 38 is completely separated from the channel groove on the lifting plate 72. In the process of screwing, the downward moving cross plate 38 is used to drive the target pole to be press-fitted to the corresponding position on the target mechanism box, and the pressing plate 76 inserted in the channel groove drives the lifting plate 72 to move downward synchronously, thereby driving the screw driver 75 to move downward synchronously, so as to realize the screwing and fixing of the mechanism box that has completed the pole crimping in the previous sequence.

[0077] The present invention also provides a method for assembling a vacuum circuit breaker using the above vacuum circuit breaker assembly equipment, which specifically includes the following operating steps:

[0078] S1: Place the target mechanism box in the material box 41, and at the same time, insert the target pole into the counterweight insert 65 on the bearing plate 64 for standby use;

[0080] S2-2: Use the step-by-step conveyor belt 62 to convey the carrier plate 64 carrying the target pole to the pole loading position, and push the clamping assembly 39 to the pole loading position to clamp the target pole through the reciprocating swing assembly, and then push the clamped target pole to the press-fitting position by the reciprocating swing assembly to press the target pole onto the target mechanism box;

[0081] S2-3: Use the laser sensor 398 to detect the alignment of the target pole and the mounting hole on the target mechanism box, and adjust the position of the pole through the servo motor to align the hole position;

[0082] S3: The target pole to be clamped in the latter sequence is pushed to the press-fitting station by the reciprocating assembly to complete the crimping. At the same time, the screw driver 75 is driven downward by the pressing plate 76 to screw and fix the mechanism box of the pole crimped in the former sequence.
