Description

Technical Field

[0001] This utility model relates to the field of moving contact riveting, specifically a moving contact riveting positioning fixture. Background Technology

[0002] Moving contacts are key components in power systems used to connect or disconnect circuits. They achieve circuit connection or disconnection through mechanical displacement and are usually used in conjunction with stationary contacts. The moving contacts need to be riveted to conduct electricity. The quality of the riveting directly affects the conductivity, mechanical strength, and product life.

[0003] In the current method of riveting moving contacts and contact points, the holes on the contact point and moving contact are aligned and riveted together. When manually aligning the contact point and moving contact, misalignment is likely to occur, resulting in poor contact or reduced mechanical strength after riveting. Therefore, a positioning fixture is needed to position the contact point. Thus, a moving contact riveting positioning fixture is proposed. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] A moving contact riveting and positioning fixture, such as Figures 1-6 As shown, the device includes a base 1, with a positioning seat 2 and a fixing seat 3 fixedly connected to the upper end of the base 1. A fixing seat 4 is fixedly connected to the back of the base 1. A material guiding component and a material feeding component are respectively fixedly connected to the upper ends of the fixing seat 3 and the fixing seat 4. The fixing seat 3 is located between the positioning seat 2 and the fixing seat 4. The positioning seat 2, the fixing seat 3, and the fixing seat 4 are adjacent and closely attached. The contact point enters the material guiding component with the larger end facing down and the smaller end facing up. The material feeding component pushes the contact point in the material guiding component into the positioning hole 10 on the positioning seat 2, and the contact point sinks into the positioning hole 10 to a certain depth.

[0026] An electric push rod 17 (model TA-01-30) is fixedly connected to the bottom of the positioning hole 10. A push plate 16 is slidably installed inside the positioning hole 10. The output end of the electric push rod 17 is used to drive the push plate 16 to rise and fall. Before riveting, the output end of the electric push rod 17 retracts to a certain extent, causing the push plate 16 to fall to a certain height. The contact enters the positioning hole 10, and the push plate 16 supports the contact. After riveting, the output end of the electric push rod 17 extends and pushes the push plate 16 upward, causing the push plate 16 to push the contact upward, making it easier for the contact to disengage from the positioning hole 10.

[0027] The positioning hole 10 has a vertically formed groove 11 on its side wall. The positioning seat 2 has a cavity 12 inside, which is located on the side wall of the groove 11 and is coaxial with the positioning hole 10. There are two sets of push plates 16, and a connecting plate 18 is fixed between the two sets of push plates 16. The connecting plate 18 slides in the groove 11. The two sets of push plates 16 and the two sets of connecting plates 18 form a "U" shape. The push plates 16 slide in the positioning hole 10, and the connecting plates 18 slide in the groove 11. The output end of the electric push rod 17 pushes the lower push plate 16 and pushes the upper push plate 16 through the connecting plate 18.

[0028] Support seats 13 are fixedly connected to the upper and lower ends of the inner wall of cavity 12. Motors 14 (model F260) are fixedly connected to both sets of support seats 13. Load-bearing plates 15 are rotatably installed at the ends of both sets of support seats 13. The output ends of the two sets of motors 14 are fixedly connected to one end of the two sets of load-bearing plates 15 respectively. The two sets of load-bearing plates 15 are arranged in an alternating manner. The ends of the two sets of load-bearing plates 15 are inserted between the two sets of push plates 16. The load-bearing plates 15 rotate within cavity 12.

[0029] When the load-bearing plate 15 rotates to the position where it enters between the two sets of push plates 16, it supports and limits the push plates 16 to prevent damage to the electric push rod 17 due to excessive riveting force. When the load-bearing plate 15 rotates to the position where it disengages from the push plates 16, the push plates 16 are no longer limited and can slide within the positioning hole 10.

[0030] The material guiding assembly includes a guide seat 6, which is fixed to the upper end of the fixed seat 3. The guide seat 6 has a horizontal material guiding groove 7 and a vertical material guiding groove 9. The horizontal material guiding groove 7 is perpendicular to the vertical material guiding groove 9 and the two are connected. The positioning hole 10 is located at one end of the vertical material guiding groove 9.

[0031] After the horizontal guide trough 7 conveys the contact point to a certain position, it enters the vertical guide trough 9 and then moves to the positioning hole 10.

[0032] The feeding assembly includes a cylinder 5, which is fixed to the upper end of the fixed base 4. The output end of the cylinder 5 is inserted into the vertical guide groove 9. The side wall of the output end of the cylinder 5 is provided with a groove 8, which is mated with the horizontal guide groove 7 and the groove 8 is mated with the positioning hole 10.

[0033] The contact point is located at a certain position in the transverse guide groove 7 and enters the groove 8. The output end of the cylinder 5 (model CDU6-10D) extends to transport the contact point in the groove 8 to the positioning hole 10.

[0034] The working principle of the moving contact riveting and positioning fixture provided by this utility model is as follows:

[0035] Motor 14 drives the load-bearing plate 15 to rotate, so that the load-bearing plate 15 supports the push plate 16. The contact point enters the guide seat 6 from the transverse guide groove 7, and then enters the groove 8. The output end of cylinder 5 extends, moving the contact point to the positioning hole 10. The moving contact is aligned and placed on the positioning seat 2. External equipment rivets the moving contact and the contact point, so that the moving contact is riveted. Motor 14 drives the load-bearing plate 15 to rotate, and the load-bearing plate 15 disengages from the push plate 16. The output end of electric push rod 17 pushes the push plate 16 upward, so that the contact point can easily disengage from the positioning hole 10. This positioning fixture can position the contact point, and the contact point can easily disengage from the positioning hole 10, thus improving the riveting quality of the moving contact and the contact point.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
