Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of power equipment manufacturing, specifically relates to a circuit breaker compression spring pin press riveting tool. BACKGROUND

[0002] 10kV outdoor vacuum on-pole circuit breaker is a key primary equipment in high-voltage power system. In its closing process, the insulating pull rod in the three-phase insulating part needs to rely on the elastic force of the overtravel spring to ensure that the movable and static contacts of the vacuum arc-extinguishing chamber can be reliably contacted and kept closed, so the riveting quality of the compression spring pin is crucial in this process. If the riveting quality of the compression spring pin is poor and the compression spring pin is not effectively fixed, the compression spring pin will fall out of the adjusting sleeve and the insulating pull rod hole and affect the normal opening and closing operation of the circuit breaker, and even cause the explosion of the vacuum arc-extinguishing chamber, etc. If the riveting force of the compression spring pin is too large, the middle end of the compression spring pin will be stressed and deformed, which will make the compression spring pin difficult to move smoothly in the insulating pull rod hole, so that the compression of the overtravel spring and the rebound process are blocked when the circuit breaker is operated, that is, the circuit breaker cannot be opened and closed instantaneously, which is easy to cause the movable and static contacts in the vacuum arc-extinguishing chamber to produce arc due to the long contact and separation time, and cause the vacuum arc-extinguishing chamber to be punctured.

[0003] The riveting method of the compression spring pin in the prior art usually adopts the artificial knocking method, that is, the worker uses a hammer or the like to knock the compression spring pin. Understandably, since the compression spring pin is knocked by the worker, the center part of the compression spring pin will be stressed and expanded due to different knocking forces, angles and positions of the workers, etc. After riveting, the compression spring pin will be blocked when moving up and down in the insulating pull rod hole, thereby directly affecting the action reliability and operation stability of the circuit breaker opening and closing, and the process controllability is poor. At the same time, since the number of insulating pull rods to be riveted is large when producing the same batch of circuit breakers, the artificial knocking riveting method of the compression spring pin not only increases the labor intensity of the workers, but also is difficult to accurately evaluate the deformation degree of the compression spring pin, which leads to the problem that the opening and closing parameters of the assembled circuit breaker are frequently unqualified in the debugging stage, thereby easily causing a large amount of rework and reducing the production efficiency.

[0028] Embodiment 1:

[0029] The utility model provides a circuit breaker spring press pin presss from both sides and rivets frock.

[0030] In an embodiment of the utility model, a circuit breaker spring press pin 101 presss from both sides and rivets frock is used for riveting the insulating pull rod 100 provided with the spring press pin 101, comprising rack 1, positioning assembly 2, limiting assembly 3 and press riveting assembly 4, positioning assembly 2 is movably installed on one side of rack 1 and is used for placing insulating pull rod 100, positioning groove 5 for the extension of spring press pin 101 is set up on positioning assembly 2, limiting assembly 3 is set up relative to positioning assembly 2 and is used for clamping and driving insulating pull rod 100 to move towards the direction close to or away from press riveting assembly 4, and press riveting assembly 4 is used for riveting the edge of spring press pin 101.

[0031] Working principle: the utility model discloses a kind of circuit breaker spring press pin presss from both sides and rivets frock, positioning assembly 2 can place the insulating pull rod 100 provided with spring press pin 101, and after being clamped and fixed by limiting assembly 3, it is driven to move to press riveting assembly 4, at this time, the end edge of spring press pin 101 is riveted by press riveting assembly 4, to realize the automatic precision riveting of spring press pin 101, convenient to use, reliable.

[0032] Specifically, as Figure 1 And Figure 2As shown in the circuit breaker spring pin press riveting tool, the rack 1 is used as the base support structure of the whole tool, and can provide a relatively stable operating environment for the positioning assembly 2, the limiting assembly 3 and the riveting assembly 4, so as to ensure the normal and orderly operation of the riveting operation. Further, since the two ends of the spring pin 101 of the insulating pull rod 100 are usually higher than the plane of the adjusting sleeve on the insulating pull rod 100, two protrusions (i.e. the two ends of the spring pin 101) are formed on the adjusting sleeve of the insulating pull rod 100. Therefore, during use of the circuit breaker spring pin press riveting tool, the worker can place the insulating pull rod 100 through the positioning assembly 2, and the two ends of the spring pin 101 are accommodated in the positioning groove 5 of the positioning assembly 2, so that the circumferential limiting of the insulating pull rod 100 can be realized, the predetermined positioning effect of the insulating pull rod 100 can be achieved, the installation angle of the insulating pull rod 100 can be automatically corrected, the centration of the spring pin 101 and the riveting assembly 4 can be ensured, the uneven stress caused by the installation deflection of the insulating pull rod 100 during riveting can be avoided, the consistency of the riveting position of each product in the same batch can be ensured, and the use is reliable.

[0033] Understandably, when the worker installs the insulating pull rod 100 provided with the spring pin 101 into the positioning assembly 2, since the limiting assembly 3 is arranged relative to the positioning assembly 2, the end of the insulating pull rod 100 naturally extends into the limiting assembly 3, so that the limiting assembly 3 can clamp the end of the insulating pull rod 100, and the axial limiting of the insulating pull rod 100 can be realized, and then the complete limiting of the insulating pull rod 100 can be realized by cooperation of the limiting assembly 3 and the positioning assembly 2, the riveting precision can be effectively prevented from being affected by the random movement of the insulating pull rod 100 during riveting, and the riveting quality of the spring pin 101 can be ensured; meanwhile, when the limiting assembly 3 stably clamps the insulating pull rod 100, the insulating pull rod 100 can be driven by the limiting assembly 3 to move towards the riveting assembly 4, after the spring pin 101 on the insulating pull rod 100 moves below the riveting assembly 4, the riveting assembly 4 can apply pressure to the edges of the two ends of the spring pin 101 and perform riveting, so as to realize the automatic and accurate riveting of the spring pin 101, which not only reduces the labor intensity of the worker and improves the riveting efficiency of the spring pin 101, but also ensures the consistency of the knocking angle and position of the riveting assembly 4 to the spring pin 101 by cooperation of the positioning assembly 2 and the limiting assembly 3, effectively avoids the influence of the stress expansion of the central part of the spring pin 101 on the normal use of the insulating pull rod 100 after the riveting of the spring pin 101 is completed, improves the action reliability and operation stability of the circuit breaker opening and closing, and has good process controllability.

[0034] It should be noted that the worker can accurately evaluate the deformation degree of the compression spring pin 101 by setting and checking the pressure size and other parameters of the riveting assembly 4, thereby effectively improving the qualification rate of the on-off parameters of the assembled circuit breaker in the debugging stage, reducing the batch rework, and greatly improving the production efficiency. In addition, when the riveting of the compression spring pin 101 is completed, the limiting assembly 3 drives the insulating pull rod 100 to move away from the riveting assembly 4, and releases the clamping and limiting of the insulating pull rod 100, so that the worker can take out the processed insulating pull rod 100 and reinstall the next insulating pull rod 100 to be processed, which is simple and convenient to operate.

[0035] In an embodiment, the riveting assembly 4 comprises a first driving member 6, a movable riveting tool 7 and a fixed riveting tool 8. The first driving member 6 is vertically arranged on the top of the rack 1. The power output end of the first driving member 6 is provided with the movable riveting tool 7. The fixed riveting tool 8 is arranged opposite to the movable riveting tool 7 and is detachably mounted on the rack 1. Specifically, as shown in Figure 1 and Figure 2 In the riveting assembly 4, the first driving member 6 can adopt a linear reciprocating driving device such as an existing air cylinder, hydraulic cylinder or electric push rod. In the embodiment, the first driving member 6 is preferably an air cylinder, which has the characteristics of simple structure, short response time and rapid pressure value change by adjusting air pressure. Since the first driving member 6 is vertically arranged on the rack 1, the movable riveting tool 7 on the power output end of the first driving member 6 can move along the height direction of the rack 1 relative to the fixed riveting tool 8, which is simple and reasonable in structure design. Further, when the riveting of the compression spring pin 101 on the insulating pull rod 100 is needed, the limiting assembly 3 can drive the insulating pull rod 100 to move and make the installed compression spring pin 101 move between the fixed riveting tool 8 and the movable riveting tool 7. After the compression spring pin 101 is moved in place, the first driving member 6 can drive the movable riveting tool 7 to apply pressure to one end edge of the compression spring pin 101, and the fixed riveting tool 8 can simultaneously apply supporting force to the other end edge of the compression spring pin 101, thereby completing the automatic and accurate riveting of the compression spring pin 101. Compared with the riveting method of artificial knocking in the prior art, the circuit breaker compression spring pin riveting tool can ensure the consistency of riveting force, angle and position parameters of the compression spring pin 101, effectively prevent the center part of the compression spring pin 101 from expanding under stress, avoid the blocking of the compression spring pin 101 when moving up and down in the hole of the insulating pull rod 100, and improve the action reliability and operation stability of the circuit breaker.

[0036] In an embodiment, the side opposite to the fixed riveting tool 8 and the movable riveting tool 7 is respectively provided with a tapered groove, and the groove wall of the tapered groove is formed with a shaped protrusion. Specifically, as shown in Figure 1 and Figure 2As shown, through the tapered groove, not only the end of the compression spring pin 101 can be smoothly inserted into the fixed riveting tool 8 and the movable riveting tool 7, but also the compression spring pin 101 can be self-adapted to the centering effect, that is, when the end of the compression spring pin 101 enters the tapered groove, a radial component force is generated to automatically correct the position deviation of the compression spring pin 101, thereby improving the accuracy of riveting of the compression spring pin 101 and the processing quality. Further, since the groove wall of the tapered groove is formed with a shaped protrusion, the shaped protrusion can press an axial groove on the surface of the compression spring pin 101, and a mechanical interlocking structure is formed between the riveting and the inner wall of the hole of the insulating pull rod 100, so as to realize the stable installation of the compression spring pin 101, and the structure design is simple and reasonable.

[0037] In an embodiment, the positioning assembly 2 comprises two second driving members 9 and a clamping sleeve 10, the two second driving members 9 are movably installed on the rack 1 at intervals, respectively, and the power output ends of the two second driving members 9 are respectively provided with a clamping sleeve 10, and the two clamping sleeves 10 can be close to or away from each other to form an installation hole 11 for placing the insulating pull rod 100 through the two second driving members 9.

[0038] Specifically, as shown in Figure 1 and Figure 2 In the positioning assembly 2 of the circuit breaker compression spring pin riveting tool, the second driving member 9 can also be a linear reciprocating driving device such as a cylinder, a hydraulic cylinder or an electric push rod in the prior art. The second driving member 9 in the embodiment is preferably a cylinder. Since the power output ends of the two second driving members 9 are respectively provided with a clamping sleeve 10, the two clamping sleeves 10 can be close to each other to form the installation hole 11 under the action of the two second driving members 9. When the compression spring pin 101 of the insulating pull rod 100 needs to be riveted, the worker only needs to install the insulating pull rod 100 into the installation hole 11 and make the two ends of the compression spring pin 101 extend into the corresponding positioning groove 5 to realize the installation and positioning of the insulating pull rod 100, which is simple to operate. It can be understood that the circuit breaker compression spring pin riveting tool meets the placement and positioning requirements of the insulating pull rod 100 by synchronously pushing the two clamping sleeves 10 to move towards each other through the two second driving members 9, which not only ensures that the compression spring pin 101 is accurately aligned with the riveting station, avoids the deviation caused by manual placement, but also enables the worker to adapt to insulating pull rods 100 of different diameters by adjusting the stroke of the two second driving members 9, thereby improving the production flexibility, simplifying the operation process, greatly improving the assembly efficiency, and being especially suitable for batch production requirements.

[0039] In an embodiment, the opposite sides of the two clamping sleeves 10 are respectively provided with notches at the top and bottom positions, and the two notches on the two clamping sleeves 10 form the positioning groove 5. It can be understood that, as shown in Figure 1 and Figure 2As shown, when the two clamping sleeves 10 abut under the action of the two second driving members 9, the corresponding notches at the top and bottom of the two clamping sleeves 10 can be precisely matched to form a complete positioning groove 5, and the two ends of the compression spring pin 101 can be naturally accommodated in the positioning groove 5, so as to realize the pre-positioning of the compression spring pin 101, and further ensure that the compression spring pin 101 maintains a correct relative positional relationship with the insulating pull rod 100 before riveting, so as to ensure the accuracy of the riveting processing of the compression spring pin 101. Further, the notches can also provide a clearance space for the two ends of the compression spring pin 101 when the clamping sleeve 10 abuts against the insulating pull rod 100, preventing interference or extrusion between the clamping sleeve 10 and the compression spring pin 101, which not only ensures the stable clamping of the insulating pull rod 100 but also avoids the stress deformation of the compression spring pin 101 in the positioning stage.

[0040] In an embodiment, the limiting assembly 3 comprises a third driving member 12, a mounting seat 13 and a plurality of limiting members 14. The third driving member 12 is detachably mounted on one side of the rack 1, and the power output end of the third driving member 12 is provided with the mounting seat 13. The mounting seat 13 is uniformly and spacedly provided with a plurality of limiting members 14 along the circumference thereof, and the plurality of limiting members 14 are all used for abutting against the outer wall of the insulating pull rod 100. As can be understood, Figure 1 and Figure 2 As shown, the third driving member 12 can adopt a linear reciprocating driving device such as a cylinder, a hydraulic cylinder or an electric push rod in the prior art. The third driving member 12 in the embodiment is preferably a cylinder. The combined structure of the mounting seat 13 and the plurality of limiting members 14 can adopt a three-jaw chuck. When the installation of the insulating pull rod 100 on the positioning assembly 2 is completed, the mounting seat 13 and the plurality of limiting members 14 move towards the positioning assembly 2 under the action of the third driving member 12, so that one end of the insulating pull rod 100 can extend to one side of the mounting seat 13. The worker can move the plurality of limiting members 14 towards the center of the mounting seat 13 by using a wrench or the like to abut against the outer wall of the insulating pull rod 100, so as to realize the multi-point clamping and fixing of the insulating pull rod 100 and ensure the installation stability of the insulating pull rod 100. Further, when the positioning assembly 2 and the limiting assembly 3 clamp and limit the insulating pull rod 100, the third driving member 12 is operated to move the compression spring pin 101 on the insulating pull rod 100 between the fixed riveting tool 8 and the movable riveting tool 7, and the first driving member 6 is operated to rivet the compression spring pin 101. The structure design is simple and reasonable.

[0041] In an embodiment, the plurality of limiters 14 are any one of a pneumatic cylinder, a hydraulic cylinder or an electric push rod, and the power output ends of the plurality of limiters 14 are provided with flexible blocks for abutting against the insulating pull rod 100. Preferably, the plurality of limiters 14 can be pneumatic cylinders, so that the insulating pull rod 100 can be quickly clamped and fixed. Compared with the mode in which the mounting seat 13 and the plurality of limiters 14 are three-jaw chucks, the plurality of limiters 14 in the embodiment are any one of a pneumatic cylinder, a hydraulic cylinder or an electric push rod, so that the worker does not need to manually fix the end of the insulating pull rod 100, the operation steps are simplified, the labor intensity of the worker is reduced, and the processing efficiency is improved. Further, when the insulating pull rod 100 needs to be clamped, the plurality of limiters 14 that are uniformly and spaced apart in the circumferential direction of the mounting seat 13 are synchronously operated, and thus the insulating pull rod 100 can be multi-point limited, so that the installation stability of the insulating pull rod 100 is ensured. In addition, by providing the flexible blocks at the power output ends of the plurality of limiters 14, sufficient contact friction is ensured to prevent the insulating pull rod 100 from rotating or displacing during the riveting process, and the elastic deformation of the flexible blocks can adapt to the shape tolerance of the insulating pull rod 100, so that surface damage caused by rigid contact is avoided, and the use is reliable.

[0042] In an embodiment, an adjusting assembly 15 is further included, which is arranged at the top of the rack 1 and is used to drive the riveting assembly 4 to move towards or away from the press spring pin 101. Specifically, as shown in Figure 1 and Figure 2 The adjusting assembly 15 can be a linear driving device such as a hydraulic cylinder or a sliding table, so that the riveting assembly 4 can move along the height direction of the rack 1 to approach or move away from the press spring pin 101, so as to adapt to insulating pull rods 100 of various sizes and meet the riveting needs of press spring pins 101 of different specifications, thereby not only expanding the use range, but also improving the use flexibility and versatility.

[0043] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
