Description

Technical Field

[0001] This utility model relates to a composite rivet contact tooling. Background Technology

[0002] like Figure 9 and 10 As shown, the existing composite rivet contact includes a contact plate 71 and a contact point 72. The contact plate 71 includes a contact bridge central section 74. The two ends of the contact bridge central section 74 are bent sequentially to form a contact bridge mating section 75 parallel to the contact bridge central section 74. A contact bridge limiting seat 76 is provided on the back of the contact bridge mating section 75. A contact bridge riveting hole 77 is provided in the contact bridge limiting seat 76. The contact point 72 includes a contact body 78 that fits against the front of the contact bridge mating section 75 and a contact riveting post 79 that passes through the contact bridge riveting hole 77. The contact body 78 has a contact hemisphere 80 on its front side, and a contact transmission gap 81 is formed between the two parallel-driven contacts 72. The composite rivet contact fixture is used for positioning when riveting the contact riveting post 79 and the contact bridge limiting seat 76. When riveting, the existing composite rivet contact fixture requires the contacts 72 and the contact plate 71 to be placed one by one, which results in low riveting efficiency and lacks a reliable limiting structure, causing the contact plate 71 and the contact 72 to be weakly riveted and easy to fall off. This needs to be improved and optimized. Utility Model Content

[0022] like Figure 1-10As shown, the composite rivet contact tooling of this utility model includes a tooling base 1, a lower support assembly 2 for supporting the contact 72 during riveting, an upper pressure plate 3 for supporting the contact plate 71 during riveting, and a clamping cylinder 4 fixed on the tooling base 1. The tooling base 1 is provided with a contact bridge receiving groove 7 for receiving the contact bridge intermediate part 74. The tooling base 1 is provided with contact transmission grooves 8 at both ends of the contact bridge receiving groove 7 for driving the contact body 78. The outer end of the contact transmission groove 8 is connected to the contact vibrating plate. The contact vibrating plate... The contact points 72 are arranged and fed into the contact transmission groove 8, causing the contacts 72 within the contact transmission groove 8 to move forward under vibration. The contact transmission groove 8 is provided with a contact clearance groove 9 for the contact hemisphere 80 to make way during transmission. The inner end of the contact clearance groove 9 is provided with a seat block 10 and a lower support action hole 12 perpendicularly communicating with the contact clearance groove 9. The diameter of the lower support action hole 12 is smaller than the diameter of the contact body 78. The seat block 10 is provided with a limiting function for the contact 72 during transmission and is perpendicular to the contact body 78. The lower support assembly 2 includes a stop block arc groove 11 concentric with the lower support action hole 12, and a lower support rod 15. The lower support rod 15 includes a lower support rod body 19 passing through the lower support action hole 12 and a lower support rod connecting part 20 connected to the output end of the lower support cylinder. The upper end of the lower support rod body 19 is provided with a lower support rod inner countersunk hole 21 for the contact hemispherical ball 80 to make way when receiving it. The upper pressure plate 3 includes an upper pressure plate connecting part 23 connected to the pressing cylinder 4 and two ends of the upper pressure plate connecting part 23. The upper pressure plate pressing part 24 presses on the contact bridge docking part 75. The upper pressure plate pressing part 24 is provided with an upper pressure plate positioning port 25 for docking and positioning of the contact bridge limiting seat 76. The contact points are transported by the contact vibration plate, eliminating the need to place the contact points 72 one by one, reducing downtime and waiting time, and effectively improving riveting efficiency. The lower support component 2 and the upper pressure plate 3 cooperate with each other to ensure that the contact points 72 and the contact plate 71 dock accurately and reliably during riveting, eliminating the risk of contact point misalignment, making the riveting more precise and firm, and suitable for large-scale contact riveting scenarios.

[0023] The back of the upper pressure plate pressing part 24 is provided with an upper pressure plate guide protrusion 27 at the front and rear ends of the upper pressure plate positioning port 25, and a silver point isolation post 28 placed in the contact transmission gap 81 for isolating the two contacts 72. The contact transmission groove 8 is also provided with a transmission groove rear limiting port 29 at the rear end of the stop block 10 in the seat body for limiting the upper pressure plate guide protrusion 27. The silver point isolation post 28 plays the role of isolating the contacts 72 during riveting, effectively preventing other contacts 72 from still moving forward in the contact transmission groove 8 when the lower support rod body 19 supports the contacts 72, ensuring the stability and reliability of the riveting action and higher safety.

[0024] The lower support assembly 2 further includes an upper balance spring 16, a lower buffer spring 17, and a spring cover 18. The lower support rod body 19 passes through the spring cover 18 and moves up and down within the lower support action hole 12. The outer wall of the lower support rod body 19 is provided with a lower support rod positioning boss 31, and the inner wall of the lower support action hole 12 is provided with an upper stop 32. The spring cover 18 covers the bottom of the lower support action hole 12, and the upper balance spring 16 is sleeved on the lower support rod body 19, with its upper end abutting against the action hole. The stop 32 has its lower end abutting against the positioning boss 31 of the lower support rod. The lower buffer spring 17 is sleeved on the lower support rod body 19, with its upper end abutting against the positioning boss 31 of the lower support rod and its lower end abutting against the spring cover 18. The upper balance spring 16 is used to prevent the lower support rod body 19 from extending out of the lower support action hole 12 in the normal state and affecting the normal transmission of the contact 72. The lower buffer spring 17 is used to provide buffering force when the lower support rod body 19 and the contact 72 are in contact, effectively preventing damage to the contact 72 caused by excessive impact force.

[0025] The bottom of the tooling base 1 is provided with a cover positioning groove 33 at the lower support action hole 12 for the installation and positioning of the spring cover 18, so that the installation is reliable and stable.

[0026] The tooling base 1 is provided with a pry opening 35 at the contact bridge receiving groove 7 to facilitate the removal of the contact bridge connecting part 74, so that personnel can quickly remove the contact plate 71 and improve riveting efficiency.

[0027] It also includes a protective plate 5, which covers the contact transmission groove 8. The protective plate 5 has a waist-shaped hole 36 and an observation port 37 at the front end for the silver point isolation column 28 to be inserted into the contact transmission groove 8. The protective plate 5 is used to prevent dust from entering the contact transmission groove 8 and affecting the normal transmission of the contact 72, thus providing better protection.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model are included within the protection scope of the present utility model.
