Description

Technical Field

[0001] This invention relates to the field of pole-mounted circuit breaker manufacturing technology, specifically to a primary and secondary integrated pole-mounted circuit breaker and its manufacturing and assembly machine. Background Technology

[0002] A primary and secondary integrated pole-mounted circuit breaker refers to a circuit breaker that deeply integrates primary and secondary equipment. It plays a vital role in the power distribution network, effectively controlling and protecting the distribution network lines to ensure the reliability and security of power supply. The assembly reliability of the solid-sealed pole and the mechanism box directly determines the insulation performance, sealing protection level and mechanical service life of the equipment.

[0003] In existing technologies, the solid-sealed pole and mechanism box of the primary and secondary integrated pole-mounted circuit breaker generally adopt an external flange bolt connection structure, which is not only cumbersome to assemble, but also prone to loosening of bolts due to long-term outdoor vibration, resulting in axial movement and circumferential deflection of the pole, which increases the contact resistance of the primary circuit and causes the secondary terminal wiring to break under stress.

[0004] Furthermore, when installing the poles to the top of the mechanism box, the existing technology mostly uses manual tightening of each pole one by one. The insertion depth and circumferential orientation of each pole are very different, which leads to deviations in the center distance of the three-phase poles and misalignment of the secondary terminals. This makes subsequent wiring difficult, results in poor consistency of the overall parameters, and affects the mechanical characteristics and insulation performance of the switch. Summary of the Invention

[0005] The purpose of this invention is to provide a primary and secondary integrated pole-mounted circuit breaker and its production and assembly machine to solve the problems in the prior art.

[0006] The objective of this invention can be achieved through the following technical solutions: Primary and secondary integrated pole-mounted circuit breakers, including: The mechanism box has multiple mounting holes and annular grooves concentrically arranged with the corresponding mounting holes on its top. Each mounting hole has a pole inserted into it. An annular water-proof strip is fixed at the bottom of the pole. An inclined pipe connected to the annular groove is fixed on one side of the mechanism box. The pole post positioning mechanism is located inside the mechanism box and is used to clamp and fix the lower end of the pole post that passes through the mounting hole. The pole post positioning mechanism consists of a clamping component and an anti-deviation component to prevent the clamping component from loosening.

The pole and mechanism box to be assembled are placed on the top of the sliding plate.

[0011] As a preferred embodiment of the production assembly machine of the present invention, the adjusting component includes an L-shaped groove on the top of the base frame located on both sides of the sink. An L-shaped platform is movably inserted into each of the two L-shaped grooves. Three limiting rods are movably inserted through the vertical sections of the two L-shaped platforms. A V-shaped clamp is fixedly connected between one end of the three limiting rods on the same side. A spring is sleeved on the outer side of the central limiting rod to fix the corresponding L-shaped platform and the V-shaped clamp. The adjustment assembly also includes guide slots on the upper side of the horizontal sections of the two L-shaped platforms and inserts fixedly connected to one side of the vertical plate. Inserts located on both sides of the inserts are also fixedly provided on one side of the vertical plate. The two inserts are directly opposite the guide slots on the corresponding L-shaped platforms. A slot is provided on one side of the base frame that is directly opposite the inserts and inserts.

[0012] As a preferred embodiment of the production assembly machine described in this invention, the pressing mechanism includes a cylinder two fixed to the top of the top frame and a lifting plate located at the bottom of the top frame. A sliding frame two is fixedly provided on the top of the lifting plate. A sliding seat fixed to the output end of the corresponding cylinder two is slidably installed on the sliding frame two. The number of cylinder two and lifting plates is equal to the number of poles to be assembled synchronously. A wedge-shaped groove is opened at one end of each lifting plate. A limiting post is fixedly provided at the top of the base frame corresponding to the position of each lifting plate.

[0013] As a preferred embodiment of the production assembly machine described in this invention, the pressing mechanism further includes a horizontal plate fixed between two adjacent lifting plates and on the opposite side of the two lifting plates that are furthest apart. One end of each of the two horizontal plates that are furthest apart is fixedly provided with an L-shaped bracket, and the bottom end of each of the two L-shaped brackets is fixedly connected with a rack.

[0014] As a preferred embodiment of the production assembly machine of the present invention, the actuating mechanism includes a column groove at one end of the lifting plate and a T-shaped column movably inserted into the column groove. A spring is fixedly connected between the end of the T-shaped column inserted into the column groove and the inner wall of the column groove. A square column movably passes through the T-shaped column, and the top of the square column movably passes through the top frame. A limiting plate is fixedly provided at the top of the square column. A circular plate is movably sleeved on the outside of the square column. Two arc grooves are opened on the circular plate and placed on both sides of the T-shaped column. Two straight grooves are opened on the T-shaped column. A lever is slidably installed at the intersection of the straight groove and the corresponding arc groove.

[0015] As a preferred embodiment of the production assembly machine of the present invention, the radial correction mechanism includes a conical cylinder fixed to the bottom of a square column. Two L-shaped columns are fixedly installed inside the conical cylinder. A horizontal bar is movably passed through the bottom of the vertical section of each of the two L-shaped columns. A baffle is fixedly fitted on the outside of each horizontal bar. A V-shaped clamp is fixedly connected to one end of each of the two horizontal bars. A spring is also fitted on the outside of each horizontal bar to fixally connect the corresponding L-shaped column and the baffle. A vertical bar is movably passed through the horizontal section of each of the two L-shaped columns. A baffle is fixedly installed on the outside of the vertical bar to restrict the vertical bar from disengaging from the through hole on the L-shaped column. A pressure seat is hinged to the bottom of the vertical bar.

[0016] The beneficial effects of this invention are: 1. The pole-mounted circuit breaker of the present invention adopts a combination waterproof design of annular water-proof strip, annular groove and inclined pipe. The annular water-proof strip is embedded in the annular groove to form a seal, which blocks most of the rainwater from seeping in. The small amount of water that seeps in is stored in the annular groove and automatically discharged outside the box along the inclined pipe, which completely avoids water seeping into the mechanism box and causing the components to get damp and the insulation to deteriorate. 2. This invention utilizes a double-sliding clamping column structure that links the gear column and the gear plate to simultaneously engage the pole column slots from both sides, resulting in uniform clamping force, good centering, and no radial displacement of the pole columns. Combined with the double anti-loosening locking of the one-way bearing stud, L-shaped swing arm, and limiting groove, it avoids the problems of pole column loosening and movement caused by outdoor vibration and short-circuit electric power. Furthermore, the entire pole column fixing structure is built into the mechanism box, making the overall shape simpler, reducing the number of sealing surfaces, and lowering the risk of water leakage. During assembly, multiple pole columns can be locked simultaneously by simply rotating the stud, making the installation and disassembly efficiency far higher than that of traditional bolt fastening methods. 3. This invention uses the vertical downward stroke of the pressing mechanism as the sole driving force to synchronously complete four core processes: radial coarse correction, radial fine correction, circumferential angle adjustment, and pole post pressing and locking, all through pure mechanical linkage. It eliminates the need for multiple independent drives and complex electrical timing control, ensuring natural synchronization of actions without signal delay. Furthermore, the synchronous pressing and locking of the three pole posts significantly improves production efficiency compared to single-station serial assembly. At the same time, the pressing depth and orientation of each pole post are more consistent. 4. This invention achieves simultaneous linkage between workpiece conveying and box clamping, enabling clamping and positioning upon material delivery. The entire process uses the same reference, avoiding reference offsets from multiple clamping operations, resulting in high assembly reliability. It also reduces the number of power components and lowers equipment manufacturing costs. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] The pole-mounted circuit breaker of this invention belongs to the category of electrical switches and is a basic power component for control and protection in power systems. It can be applied to distribution networks containing power electronic components (such as photovoltaic inverters, energy storage converters, SVG, etc.) and can also serve as upstream protection for grid connection points, disconnecting lines in the event of system-level faults. As a fundamental core device for smart distribution network protection in the smart grid industry, the pole-mounted circuit breaker is one of the core basic safety conditions for large-scale grid connection of new energy. Among them, assembling the poles and mechanism box of the pole-mounted circuit breaker is a process in the production of pole-mounted circuit breakers. This solution only requires rotating the stud to complete the synchronous locking of multiple poles, and with the cooperation of the one-way bearing stud, L-shaped swing arm, and limit groove, a double anti-loosening locking is achieved.

[0022] The production assembly machine of this invention belongs to the intelligent manufacturing equipment industry. It is used to simply assemble metal parts and non-metal parts together. It is a part of an industrial robot. It uses the vertical downward stroke of the pressing mechanism as the only driving force to complete four core processes in pure mechanical linkage: radial coarse correction, radial fine correction, circumferential angle adjustment, and pole post pressing and positioning. This enables the automated assembly of the pole post and mechanism box of the pole-mounted circuit breaker.

[0023] Refer to the instruction manual appendix Figure 1 and Figures 5-7 The device provides a primary and secondary integrated pole-mounted circuit breaker, including a mechanism box 1, three poles 2, a pole locking mechanism 3, and a drainage assembly. The mechanism box 1 is a stainless steel welded shell with three mounting holes on the top corresponding to the poles 2. Each mounting hole has a coaxial annular groove on its outer periphery. An annular water-proof strip is fixedly installed on the bottom outer wall of the pole 2. After the pole 2 is inserted into the mounting hole, the annular water-proof strip is precisely embedded in the annular groove, forming a waterproof barrier. An inclined drain pipe 4 is fixedly installed on one side of the mechanism box 1. The inner end of the inclined drain pipe 4 is connected to the bottom of the corresponding annular groove, and the outer end extends downward to the outside of the mechanism box 1, forming a drainage assembly. This allows water that seeps into the annular groove to be automatically discharged along the inclined drain pipe 4, preventing it from accumulating and seeping into the interior of the mechanism box 1.

[0024] The pole post positioning mechanism 3 is set inside the mechanism box 1 and consists of two parts: a clamping component and an anti-deviation component. It is used to clamp and lock the pole post 2 from the bottom simultaneously, and at the same time, prevent the clamping structure from loosening due to vibration, so as to achieve boltless and rapid fixing of the pole post 2.

[0025] Furthermore, such as Figures 1-7As shown, the clamping assembly includes sliding frames 31 symmetrically fixed on both sides of the inner cavity of the mechanism box 1, and two symmetrically arranged slots 38 opened on the lower outer side of each pole post 2. Two parallel sliding clamping posts 32 are slidably installed between the two sliding frames 31. Toothed plates 33 are fixed at both ends of the opposite sides of the two sliding clamping posts 32. The two toothed plates 33 located at the same end are staggered in the vertical direction, and slots adapted to the toothed plates 33 on the corresponding sliding clamping post 32 are opened to avoid motion interference.

[0026] Furthermore, the clamping assembly also includes two symmetrical through-threaded studs 34 that are threaded onto both ends of the mechanism housing 1. The outer end of each stud 34 is fixedly connected to a gear post 35, and the inner end is fixedly connected to a gear post 36. The gear post 36 located inside the mechanism housing 1 meshes with the upper and lower gear plates 33 at the same end. Both studs 34 are configured as two-section structures, and the two sections are rotatably connected by a one-way bearing. Only the studs 34 are allowed to rotate unidirectionally in the locking direction. The outer ends of the two studs 34 facing away from each other are provided with cross grooves 37. The cross grooves 37 penetrate the rotational connection area between the two sections. After inserting a special tool (such as a cross pin), bidirectional constraint is achieved, so as to achieve the purpose of reversing the rotation to release the clamping state of the sliding clamping column 32.

[0027] It should be noted that during the installation of pole post 2, after pole post 2 is inserted into the installation hole, the tool is used to rotate gear post 1 35 to drive stud 34 to rotate in the direction of locking the one-way bearing, so that gear post 2 36 rotates synchronously, and through the two misaligned meshing tooth plates 33, the two sliding clamping posts 32 move synchronously towards each other along the sliding frame 1 31. The two sliding clamping posts 32 are respectively inserted into the corresponding slots 38 on the lower end of pole post 2, clamping pole post 2 synchronously from both sides, thereby fixing pole post 2 axially and radially. The one-way bearing can ensure that stud 34 can only rotate in the locking direction and will not rotate back and loosen on its own when subjected to vibration.

[0028] Furthermore, such as Figures 1-4 As shown, the anti-deviation assembly includes through slots 39 at both ends of the mechanism box 1. A disc 310 is rotatably installed inside each through slot 39. A protruding plate 311 located outside the mechanism box 1 is fixedly connected to the outer side of each disc 310. An L-shaped swing arm 312 located inside the mechanism box 1 is fixedly connected to the inner side of each disc 310. A spring 314 is fixedly connected between the two L-shaped swing arms 312 and the corresponding side of the inner wall of the mechanism box 1. A limit groove 313 is opened on the outer side of one end of the two studs 34 that connect to the gear column 36.

[0029] It should be noted that, under normal conditions, the spring 314 pulls the end of the L-shaped swing arm 312 into the limiting groove 313 of the stud 34, forming a circumferential lock on the stud 34, further restricting the rotation of the stud 34, and preventing the clamping from loosening due to outdoor vibration or short-circuit electric power. When adjustment or disassembly is required, the external convex plate 311 is moved to drive the disc 310 to rotate, allowing the end of the L-shaped swing arm 312 to disengage from the limiting groove 313, and then the stud 34 can be rotated for adjustment. Example

[0030] Refer to the instruction manual appendix Figure 8 and Figure 16 This embodiment is the first embodiment of the present invention, which provides a production and assembly machine for a primary and secondary integrated pole-mounted circuit breaker, used to simultaneously press three poles 2 onto the top of the mechanism box 1 and complete the locking and clamping. The whole includes a bearing part 5 and a pressing part 6.

[0031] Furthermore, such as Figures 8-11 As shown, the support unit 5 includes a base frame 51, a feeding assembly for intermittently pushing the mechanism box 1 and pole post 2 to be assembled to the target assembly station, and an adjustment assembly for clamping and positioning the mechanism box 1 fed into the assembly station. The feeding assembly includes a cylinder 52 (model DSTA-SD80 / 50 / 32-1500-3S) fixedly installed at the bottom of the base frame 51 and a recess 54 opened at the top of the base frame 51. The output end of the cylinder 52 is fixedly connected to a vertical plate 53. A sliding plate 55 is movably embedded in the recess 54. The sliding plate 55 is fixedly connected to the vertical plate 53. The mechanism box 1 and pole post 2 to be assembled are pre-placed on the top of the sliding plate 55. The cylinder 52 reciprocates to drive the sliding plate 55 carrying the target assembly parts from the loading station into the assembly station.

[0032] Furthermore, the adjustment assembly consists of adjustment units symmetrically arranged on both sides of the settling tank 54. Each adjustment unit includes an L-shaped groove 56 opened on the top of the base frame 51. An L-shaped platform 57 is movably inserted inside the L-shaped groove 56. Three horizontally collinear parallel limiting rods 58 are movably passed through the vertical section of the L-shaped platform 57. A V-shaped clamp 59 is fixedly connected between the inner end faces of the three limiting rods 58. A spring 510 is sleeved on the outer side of the central limiting rod 58. The two ends of the spring 510 are fixedly connected to the L-shaped platform 57 and the V-shaped clamp 59, respectively.

[0033] Furthermore, guide grooves 511 with inclined surfaces are opened on the upper side of the horizontal section of the two L-shaped platforms 57. A column 513 is fixed on the side of the vertical plate 53 facing the assembly station. Insert strips 512 are symmetrically provided on both sides of the column 513 and fixedly connected to the side of the vertical plate 53. The two insert strips 512 are respectively aligned with the guide grooves 511 of the corresponding side of the L-shaped platform 57. Slots are opened at corresponding positions on the side wall of the base frame 51 to allow the column 513 and insert strips 512 to extend and avoid each other.

[0034] It should be noted that a conveyor belt is installed at both ends of the vertical plate 53 on the feeding side of the base frame 51. When the cylinder 52 pushes the sliding plate 55 out of the sink 54, the conveyor belt is started to complete one round of feeding, realizing the delivery of the target part to be assembled into the assembly station and the replacement of the target part after assembly. During the feeding of the vertical plate 53 and the sliding plate 55 to the assembly station by the cylinder 52, the insert 512 is inserted into the guide groove 511 at the same time. The inclined surface inside the guide groove 511 pushes the two L-shaped platforms 57 to move synchronously towards each other along the L-shaped groove 56, which drives the two V-shaped clamps 59 to move closer together at the same time, clamping the mechanism box 1 from both sides. At the same time as the feeding is in place, the mechanism box 1 automatically centers and clamps, without the need for additional clamping drive. When the cylinder 52 retracts, the insert 512 exits the guide groove 511, and the spring 510 pushes the V-shaped clamps 59 to automatically open and release the workpiece, realizing the pure mechanical linkage of feeding and clamping. Example

[0035] Refer to the instruction manual appendix Figure 8 , Figure 9 This embodiment is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the pressing part 6 includes a top frame 61 fixed to the top of the base frame 51. Between the top frame 61 and the base frame 51, there is a radial correction mechanism 64 for correcting the radially offset pole post 2, a toggle mechanism 63 for adjusting the orientation of the pole post 2, and a pressing mechanism 62 for driving the pole post locking mechanism 3 to complete the locking of the pole post 2. The pressing stroke of the pressing mechanism 62 also serves as the power source for the toggle mechanism 63 and the radial correction mechanism 64, and the three are mechanically linked.

[0036] Furthermore, such as Figure 9 and Figures 12-14 As shown, the pressing mechanism 62 includes three sets of cylinders 621 (model DSA25N200) fixed to the top of the top frame 61, and three lifting plates 622 correspondingly set at the bottom of the top frame 61. Each lifting plate 622 has a sliding frame 623 fixed to its top, and a sliding seat 624 is slidably installed on the sliding frame 623. The sliding seat 624 is fixedly connected to the output end of the corresponding cylinder 621. The number of cylinders 621 and lifting plates 622 is the same as the number of pole posts 2, which can form three sets of actuation units to realize the synchronous pressing of the three pole posts 2. Each lifting plate 622 has a wedge groove 625 at one end. A limit post 626 is fixed at the corresponding position on the top of the base frame 51. The limit post 626 is composed of three trapezoidal posts and a connecting plate connecting the three trapezoidal posts. When the lifting plate 622 descends to the set depth, the wedge groove 625 fits and limits the limit post 626 to ensure that the pressing depth of the pole post 2 is consistent.

[0037] Furthermore, a horizontal plate 627 is fixed between two adjacent lifting plates 622 and on the outer side of the two lifting plates 622. An L-shaped bracket 628 is fixed on the outer side of the two horizontal plates 627 that are furthest apart. A rack 629 is fixedly connected to the bottom end of the two L-shaped brackets 628. The rack 629 can cooperate with the transmission structure at both ends of the mechanism box 1 to realize the auxiliary synchronous verification of the downward stroke.

[0038] It should be noted that during the process of pressing down and assembling the pole post 2 pre-inserted into the top of the mechanism box 1, the lifting plate 622 is pushed down as a whole by the cylinder 621. During the downward movement, the lifting plate 622 first drives the radial correction mechanism 64 to complete the radial position correction of the pole post 2. Then, after the upper end of the trapezoidal column is inserted into the wedge groove 625 on the corresponding lifting plate 622, the inclined surface of the wedge groove 625 will guide the lifting plate 622 to move laterally while moving down, triggering the toggle mechanism 63 to adjust the orientation of the secondary terminals on the pole post 2, and drive the rack 629 to approach the gear post 35 on the mechanism box 1 to complete the meshing. During the meshing process between the rack 629 and the corresponding gear post 35, one end of the moving rack 629 will press the protruding plate 311 on the side of the corresponding side disc 310 to release the limiting state of the L-shaped swing arm 312 on the stud 34. After the orientation of the secondary terminals on the pole post 2 is completed, the lifting plate 622 enters the vertical downward stage. During this process, as the lifting plate 622 continues to move downward, it will synchronously drive the rack 629 downward, and use the downward rack 629 to drive the corresponding gear column 35 to rotate, providing rotational power for the actuating mechanism 63. This achieves the synchronous clamping of the three sets of pole posts 2 during the vertical downward stage of the lifting plate 622. Compared with the traditional bolt installation, the design of this clamping mechanism makes the disassembly and assembly of the pole posts 2 more convenient and faster.

[0039] Furthermore, such as Figure 9 and Figures 12-14As shown, the actuating mechanism 63 is used to automatically adjust the orientation of the pole post 2 in the circumferential direction during the pressing process to ensure that the secondary terminals are aligned. Each actuating unit includes a groove at one end of the lifting plate 622. A T-shaped post 631 is movably inserted into the groove. A spring 634 is fixedly connected between the inner end of the T-shaped post 631 and the inner wall of the groove. A square post 635 is vertically and movably inserted through the T-shaped post 631. The top of the square post 635 movably passes through the top frame 61 and is fixed with a limiting plate 636. The limiting plate 636 is used to prevent the square post 635 from falling off. A circular plate 637 is also movably fitted on the outside of the square post 635. In the circular plate 637, the perforation of the square column 635 fits perfectly with the square column 635, while the length of the perforation of the square column 635 on the T-shaped column 631 is greater than the length of the square column 635. The circular plate 637 has two symmetrically arranged arc grooves 638, and the T-shaped column 631 has two horizontally collinear straight grooves 632. A lever 633 is slidably installed at the junction of the straight groove 632 and the arc groove 638. Each lever 633 consists of a section slidably connected inside the straight groove 632 and a straight rod section connected to the lower end of the section, ensuring that the lever 633 never disengages from the corresponding straight groove 632.

[0040] It should be noted that during the lateral movement of the descending lifting plate 622 guided by the inclined surface of the wedge groove 625, the square column 635 maintains circumferential limitation on the circular plate 637 in the vertical direction. This causes the T-shaped column 631 to move laterally simultaneously when the lifting plate 622 moves laterally, and pulls the lever 633 to move along the corresponding arc groove 638. This causes the two levers 633 to converge synchronously in the direction of the secondary terminal target, completing the orientation adjustment of the secondary terminal on the pole 2. This ensures that after the lifting plate 622 moves laterally into position, the three sets of levers 633 synchronously adjust the orientation of the secondary terminal on the pole 2 to be consistent. The setting of the spring 634 can absorb the lateral excess after the orientation of the secondary terminal is adjusted to be in place, avoiding damage to the pole 2 by hard-hitting. Conversely, when the lifting plate 622 moves upward, the T-shaped column 631 resets, and the lever 633 opens in the opposite direction along the arc groove 638 to avoid the pole 2.

[0041] Furthermore, such as Figure 9 and Figure 15 As shown, the radial correction mechanism 64 is used to automatically center the pole post 2 during the initial pressing to eliminate radial offset. Each radial correction mechanism 64 includes a cone 641 fixed to the bottom of the square post 635. Two L-shaped posts 642 are symmetrically fixed inside the cone 641. A horizontal bar 643 is movably passed through the bottom of the vertical section of each of the two L-shaped posts 642. A retaining frame 644 is fixedly fitted on the outside of each horizontal bar 643. A V-shaped clamp 645 is fixedly connected to the opposite end of each of the two horizontal bars 643. A spring 646 is also fitted on the outside of each horizontal bar 643. The two ends of the spring 646 abut against the L-shaped post 642 and the retaining frame 644, respectively.

[0042] Furthermore, vertical strips 647 are movably inserted through the horizontal sections of both L-shaped posts 642. A stop block is fixed on the outside of the vertical strip 647 to prevent the vertical strip 647 from detaching from the L-shaped post 642. A pressure seat 648 is hinged to the bottom end of the vertical strip 647 to better adapt to the outer wall line of the pole post 2. In order to reduce the resistance encountered by the pole post 2 during radial movement correction, rolling balls can be rolled and embedded on the lower end face of the cone 641 and the pressure seat 648 to convert the static friction force encountered by the pole post 2 during movement into rolling friction, thereby avoiding scratches on the surface of the pole post 2.

[0043] It should be noted that a buffer spring is fitted on the outer side of the square column 635, located between the circular plate 637 and the conical cylinder 641. During the downward movement of the lifting plate 622 via the cylinder 621, the square column 635 first drives the conical cylinder 641 downward. The lower end of the inner conical surface of the conical cylinder 641 first covers the top of the pole post 2, completing the first-stage coarse radial correction by relying on the conical surface guidance. Then, continuing downward, the pressure seat 648 contacts the terminal post at the upper end of the pole post 2, and the reaction force pushes the vertical bar 647 upward relative to the L-shaped column 642. The inclined plane pushes the two horizontal bars 643 to move towards each other, and the two V-shaped clamping plates 645 retract synchronously, clamping the terminal post part at the upper end of the pole post 2 from both sides to complete the secondary fine radial correction. During this process, the spring 646 can push the V-shaped clamping plate 645 to reset after the lifting plate 622 moves upward. After the correction is completed, as the lifting plate 622 continues to move downward, it will tightly press the pole post 2 into the mounting hole. As the downward pressing process proceeds, the pole post 2 will compress the corresponding buffer spring in the opposite direction until the external drive triggers the pole post locking mechanism 3 to complete the clamping and locking.

[0044] The working principle of the above-mentioned production assembly machine is as follows: The pole post 2 to be assembled is pre-installed inside the mounting hole at the top of the mechanism box 1, and the mechanism box 1 is placed on the conveyor belt. The conveyor belt pushes the mechanism box 1 with the pre-installed pole post 2 to the top of the sliding plate 55 extending out of the sink 54. Then, the cylinder 52 pushes the sliding plate 55 to send the workpiece into the assembly station. Simultaneously, the insert bar 512 and the corresponding guide groove 511 drive the V-shaped clamping plates 59 on both sides to center and clamp the mechanism box 1. Then, the cylinder 621 controls the lifting plate 622 to move downward, so that the cone 641 moves downward synchronously. The cover is placed over the pole post 2, causing the two V-shaped clamps 645 to retract synchronously, completing the radial correction of the pole post 2. Then, the lifting plate 622 is controlled to descend, allowing the T-shaped column 631 to drive the lever 633 to swing along the arc groove 638, turning the pole post 2 to the standard orientation, ensuring that the secondary terminals are in the same position. After the pole post 2 is corrected, the rack 629, which descends synchronously with the lifting plate 622, will drive the corresponding gear column 35 to rotate, triggering the pole post locking mechanism 3 to lock and fix the three sets of pole posts 2 synchronously. Finally, each mechanism is reset, and after waiting for the material to be fed again, the next round of assembly operation is started.
