Abstract
Description
Technical Field
[0001] This utility model relates to the field of riveting technology, and more specifically, to a fully automatic feeding and riveting device for arc-starting plates suitable for air switches. Background Technology
[0002] An air switch, also known as an air circuit breaker, is a type of circuit breaker. It is a switch that automatically disconnects the circuit whenever the current exceeds the rated current. Air switches are a very important electrical appliance in low-voltage power distribution networks and electric drive systems, integrating control and multiple protection functions. In addition to connecting and disconnecting circuits, they can also protect against short circuits, severe overloads, and undervoltage in circuits or electrical equipment.
[0003] An air circuit breaker includes at least contacts and an arc-starting piece riveted to the contacts. For example, patent announcement number CNCN207746312U relates to an arc-starting piece riveting fixture for a frame circuit breaker, including a stationary contact and an arc-starting piece. This fixture includes a power mechanism, a positioning and fixing mechanism, and an upper punch. The power mechanism includes an upper baffle, an upper fixing plate, a lower base plate, a guide post, and a spring. The positioning and fixing mechanism includes a limit plate, a rear baffle, an arc-starting piece pressure post, an arc-starting piece pad, and an arc-starting piece baffle. The upper punch is fixed below the upper fixing plate. However, in this fixture, the arc-starting piece needs to be riveted to a designated position on the contact. This operation is usually performed manually or by a robot, resulting in time-consuming and labor-intensive work, reducing efficiency. Furthermore, due to dimensional deviations in the contact housing during injection molding, this fixture is prone to damaging the contact housing during assembly, affecting the yield rate and exhibiting significant limitations.

[0028] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0029] like Figures 1 to 4 As shown, this utility model discloses a fully automatic feeding and riveting device for arc-initiating plates suitable for air switches. It includes a carrier 1 for supporting contacts 200, a machine platform 2 on one side of the carrier 1, and a conveying assembly 3 on the machine platform 2 for sorting and conveying the arc-initiating plates 100 one by one. The conveying assembly 3 includes at least an arc-shaped conveying block 31 fixed on the machine platform 2. A conveying channel is formed within the conveying block 31, with a feed inlet 32 at the top and a feed connector 33 at the feed inlet 32. The bottom of the conveying channel is located on one side of and close to a positioning assembly 4. A conveying groove 34 is formed on one side of the conveying block 31, communicating with the conveying channel, and the width of the conveying groove 34 is equal to the diameter of the positioning end 101 of the arc-initiating plate 100. This ingenious design allows the conveying channel and the conveying groove 34 to work together to neatly arrange the arc-initiating plates 100 within the conveying channel, thereby adapting to large-scale processing procedures and improving work efficiency.
[0030] In this application, a telescopic cylinder 35 is fixedly mounted on the machine base 2. A limiting block 36 is fixedly mounted on the cylinder shaft of the telescopic cylinder 35. A first limiting piece 37 and a second limiting piece 38 are fixedly mounted on the limiting block 36. The first limiting piece 37 and the second limiting piece 38 are located on both sides of the conveying groove 34, and the distance between the first limiting piece 37 and the second limiting piece 38 is less than the diameter of the positioning end 101. The distance between the first limiting piece 37 and the second limiting piece 38 is equal to or greater than the diameter of the positioning end 101. By extending or retracting the telescopic cylinder 35, the limiting block 36 can be driven to move horizontally. This allows the first limiting piece 37 to make way for the lowermost arc-inducing piece 100, and the second limiting piece 38 to limit the arc-inducing pieces adjacent to the lowermost arc-inducing piece 100. This enables the arc-inducing pieces 100 to be conveyed one by one. This operation is simple, convenient, stable, reliable, and has wide applicability.
[0031] One side of the conveying assembly 3 is provided with a positioning assembly 4 for receiving and positioning the arc-inducing piece 100. A driving assembly 5 is provided above the positioning assembly 4, and the driving assembly 5 and the positioning assembly 4 are connected by a floating assembly 6.

[0032] The floating assembly 6 includes at least a guide block 61 slidably mounted on the guide rail 41. A guide plate 62 is fixedly mounted on the guide block 61. A guide rod 63 and a riveting rod 7 are fixedly mounted on the guide plate 62. The other end of the guide rod 63 passes through the guide plate 43. A return spring 64 is sleeved on the guide rod 63. One end of the return spring 64 is connected to the guide plate 62, and the other end is connected to the guide plate 43. The driving assembly 5 includes at least an electric cylinder 51 fixedly mounted on the machine base 2. The cylinder shaft of the electric cylinder 51 is fixedly connected to the guide plate 62 via a connecting seat 52. A riveting rod 7 is fixedly mounted on the guide plate 62. The riveting rod 7 can pass through the positioning assembly 4 to rivet the arc-inducing piece 100 it positions onto the contact 200. The above layout is reasonable and ingeniously designed. The setting of the return spring 64 in the floating assembly 6 allows the positioning clamp 46 to float up and down relative to the contact 200, avoiding pressure damage to the contact, reducing scrap costs, and improving the yield rate.
[0033] In a preferred embodiment of this utility model, the carrier 1 includes a base plate 11 and a fixed seat 12 disposed thereon. A column 19 is fixedly mounted on the fixed seat 12, and a support 13 is slidably mounted on the column 19. In this application, an elastic spring (not shown in the figure) is sleeved on the column 19. One end of the elastic spring abuts against the support 13, and the other end abuts against the fixed seat 12. A bearing groove adapted to the contact 200 is formed on the support 13. A support column 14 is fixedly mounted on the machine base 2. A limiting column 15 is provided directly above the support column 14. The limiting column 15 consists of a large-diameter end 151 and a small-diameter end 152. A limiting stop 16 is fixed on the small-diameter end 152.

A limiting plug 17 is fixedly provided on the cylinder shaft of the limiting cylinder. The limiting plug 17 can abut against the limiting stop 16.
[0034] The working process of this utility model is briefly described below:
[0035] The arc-inducing piece 100 is conveyed from the feed inlet 32 into the conveying channel. The positioning end 101 of the arc-inducing piece 100 is placed in the conveying groove 34. The lowermost arc-inducing piece 100 is blocked by the first limiting piece, and the arc-inducing piece adjacent to the lowermost arc-inducing piece 100 is blocked and limited by the second limiting piece.
[0036] The contact 200 is placed into the bearing groove of the support 13. After placement, the telescopic cylinder 35 controls the limiting block to retract. The first limiting block makes way for the arc-inducing piece 100 located at the bottom, so that it falls from the conveying channel into the receiving groove formed at the bottom of the positioning clamp 46.
[0037] The electric cylinder 51 extends, driving the positioning chuck 46 downwards via the guide plate 62 and the return spring 64 until the positioning chuck 46 abuts against the contact 200. At this point, the electric cylinder 51 continues to extend, and the riveting rod 7, passing through the receiving groove, continues to drive the arc-inducing plate 100 downwards. The riveting rod 7 presses against the contact 200 via the arc-inducing plate 100, driving the support 13 to slide on the column 19. The support 13 drives the limiting post 15 downwards until the limiting stop 16 abuts against the support column 14. At this point, the limiting cylinder extends, driving the limiting plug 17 to abut against the limiting stop 16, facilitating work at other stations (such as inspection).
[0038] After all workstations have completed their work, the limit cylinder seat retracts, and the limit plug 17 separates from the limit stop 16. At this time, under the action of the lifting spring, the limit post 15 pushes the contact after riveting out from the support 13, completing the unloading.
[0039] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
[0040] The detailed descriptions listed above are merely specific descriptions of feasible implementations of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
