Description

Technical Field

[0001] This utility model relates to a stationary contact tooling for contactors. Background Technology

[0002] like Figure 8 As shown, the existing contactor stationary contact structure includes a stationary contact plate 71 and stationary contact points 72 riveted to both ends of the stationary contact plate 71. The stationary contact plate 71 includes a stationary contact plate arc swing portion 73. The two ends of the stationary contact plate arc swing portion 73 extend outward sequentially to form stationary contact plate swing portions 74. The stationary contact plate swing portions 74 bend outward to form a stationary contact plate contact portion 75 that is riveted to the stationary contact point 72. Since the two ends of the stationary contact plate arc swing portion 73 are not on the same horizontal plane, the existing contactor stationary contact tooling has limited positioning and limiting structure for the stationary contact plate 71 and stationary contact point 72 during riveting. The stationary contact plate 71 and stationary contact point 72 have a certain amount of room for movement on the tooling, and cannot be firmly fixed in the correct riveting position during riveting. This results in the stationary contact point 72 and the stationary contact plate contact portion 75 not being accurately aligned, and deviations are prone to occur during riveting, leading to poor riveting accuracy and low riveting yield. Improvements and optimizations are made to address this issue. Utility Model Content

[0007] The bottom of the inner clamp of the stationary contact plate limiting block is provided with a limiting block T-shaped part, and the receiving seat fixing block is provided with a fixing block guide groove that guides the T-shaped part of the limiting block when it moves.

[0008] The stationary contact receiving and limiting assembly also includes a buffer spring. The upper end face of the receiving seat mounting part is provided with a spring positioning groove for positioning the buffer spring. The buffer spring is placed within the stroke gap of the receiving seat, with its lower end placed in the spring positioning groove and its upper end abutting against the limiting port of the fixed block.

[0009] The cylinder connecting block has a U-shaped structure, and the tooling base plate is provided with a square guide hole for the cylinder connecting block to pass through.

[0010] The advantages of this contactor stationary contact tooling are: the upper limit of the stationary contact plate is achieved by the first limiting block and the second limiting block of the stationary contact plate, and the negative pressure adsorption is applied during the riveting of the stationary contact point, which effectively reduces the positional displacement of the stationary contact plate and the stationary contact point when subjected to vibration or movement during riveting, making the riveting more controllable, with high riveting accuracy and good riveting effect.

The cylinder connecting block 10 passes through the fixture base plate 6 and drives the contact receiving seat 7 to move upward. A receiving seat stroke gap 22 is formed between the receiving seat mounting part 14 and the fixing block limiting hole 20. The first limiting block 11 and the second limiting block 12 of the stationary contact plate both include a stationary contact plate limiting block inner clamping part 25. The clamping part 25 is movably fixed on the receiving seat fixing block 8. The inner side of the first limiting block 11 of the stationary contact plate is provided with a limiting block round rod 26 for the upper limit of the arc swing part 73 of the stationary contact plate. The second limiting block 12 of the stationary contact plate is provided with a round rod positioning hole 27 that mates with the limiting block round rod 26. The upper limit of the stationary contact plate 71 is achieved by the first limiting block 11 and the second limiting block 12 of the stationary contact plate, which effectively reduces the positional displacement of the stationary contact plate when it is vibrated or moved during riveting, making the riveting more controllable, with high riveting accuracy and good riveting effect.

[0021] It also includes a stationary contact limiting component 4, which includes an adsorption rod 30 and an adsorption rod fixing block 31 for adsorbing the stationary contact 72 during riveting. The adsorption rod 30 includes an adsorption rod body 32 and an adsorption rod limiting head 33 passing through the adsorption rod fixing block 31. The receiving seat recess 19 is provided with an adsorption rod docking hole 35 for docking the adsorption rod body 32.

The adsorption rod 30 is provided with an adsorption rod air vent 38 that runs vertically through the rod, which can perform negative pressure adsorption on the stationary contact 72 during riveting, ensuring that the stationary contact 72 does not shift during riveting, avoiding displacement caused by vibration during riveting, and improving riveting accuracy.

[0022] The tooling base plate 6 is provided with a base plate air inlet 40 communicating with the air outlet 38 of the adsorption rod and a base plate air extraction hole 41 communicating perpendicularly with the base plate air inlet 40. The base plate air extraction hole 41 is connected to an external vacuum pump.

[0024] The stationary contact receiving and limiting assembly 3 also includes a buffer spring 13. The upper end face of the receiving seat mounting part 14 is provided with a spring positioning groove 46 for positioning the buffer spring 13. The buffer spring 13 is placed in the travel gap 22 of the receiving seat, with its lower end placed in the spring positioning groove 46 and its upper end abutting against the fixed block limiting port 20. The buffer spring 13 effectively prevents excessive impact force from damaging the contact receiving seat 7 and the stationary contact.

[0025] The cylinder connecting block 10 has a U-shaped structure, and the tooling base plate 6 is provided with a square guide port 47 for the cylinder connecting block 10 to pass through. The U-shaped structure makes the transmission smoother and the operation more reliable.

[0026] Riveting process: Place the stationary contact 72 in the sink groove 19 of the receiving seat body 15, and then place the stationary contact plate arc swing part 73 of the stationary contact plate 71 in the arc insertion groove 16. Manually move the first limiting block 11 and the second limiting block 12 of the stationary contact plate inward to clamp them, so that the limiting block round rod 26 blocks above the arc swing part 73 of the stationary contact plate and aligns with the round rod positioning hole 27. The suction rod air hole 38 of the suction rod 30 draws air to adsorb and fix the stationary contact 72. The riveting cylinder device 2 presses down to rivet the contact part 75 between the stationary contact 72 and the stationary contact plate. At the same time, the lower support cylinder 9 moves upward, driving the receiving seat body 15 to move upward for support, thereby realizing the riveting of the stationary contact 72 and the stationary contact plate 71.
