Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, and more specifically to a clamping riveting mechanism. Background Technology

[0002] Car audio systems hold an irreplaceable position as the most frequently used component in a vehicle, and better sound quality has become an important reference standard for consumers when choosing new energy vehicles. Therefore, there is a significant market demand for car audio wiring harnesses. Most car audio wiring harnesses consist of four parts riveted together: a fiberglass board, aluminum rivets, and two welding tabs. The aluminum rivets are pressed and riveted from top to bottom on the front of the wiring harness, while the welding tabs on the left and right sides are installed on the front and riveted on the back.

[0003] The existing process involves riveting the aluminum rivet column and the two welding pieces separately, all from top to bottom. Riveting these three parts requires three riveting operations, moving the fiberglass board to multiple riveting locations, and flipping it over, which is very troublesome and inefficient.

[0011] For example, see below. Figures 1 to 5 As shown, a clamping riveting mechanism includes an upper clamping cylinder 10 and a lower clamping cylinder 20. The lower clamping cylinder 20 is fixed on the bottom surface of a horizontal fixed plate 100 of the frame. The top end of the push rod of the lower clamping cylinder 20 extends out of the top end of the vertical through hole of the horizontal fixed plate 100. Side support plates 11 are fixed on the top surface of the horizontal fixed plate 100 on both sides of the vertical through hole. The same intermediate support block 12 is fixed in the middle of the top surface of the two side support plates 11. Multiple vertical columns are fixed on the top surface of the two side support plates 11. The upper mounting plate 19 is fixed on the top surface of all the vertical columns. The upper pressing cylinder 10 is fixed on the top surface of the upper mounting plate 19. The bottom end of the push rod of the upper pressing cylinder 10 extends out of the bottom end of the middle through hole of the upper mounting plate 19. The bottom end of the push rod of the upper clamping cylinder 10 is fixed with an upper riveting block 30. The upper riveting block 30 is inserted into the central through groove 121 of the intermediate support block 12, and the bottom of the upper riveting block 30 extends out of the bottom end of the central through groove 121. The central through groove 121 is a rectangular through groove, and the upper riveting block 30 is also a rectangular block, which cooperates with the central through groove 121.

[0012] Furthermore, a first intermediate support block 14 is fixed between the middle parts of the two side support plates 11. The left and right parts of the middle part of the first intermediate support block 14 are both formed with lower vertical through holes 15. The top of the push rod of the lower pressing cylinder 20 is fixed with a lifting block 21. Two lower riveting columns 211 are fixed or formed on the lifting block 21. The lower riveting columns 211 are inserted into the corresponding lower vertical through holes 15, and their tops extend out of the top of the lower vertical through holes 15. The top of the lower riveting column 211 is formed with a four-sided pyramidal riveting head 212.

[0013] The two side support plates 11 have centrally extending positioning side through grooves formed in the middle of their opposing walls. The left and right parts of the first intermediate support block 14 are inserted into the corresponding centrally positioned side through grooves and are fixedly connected to the two side support plates 11 by bolts.

[0014] Furthermore, the top surface of the first intermediate support block 14 has two upwardly extending positioning protrusions 141 formed in the middle, and a slot is formed between the two positioning protrusions 141. The conveying beam 40 is located behind the first intermediate support block 14. The front end face of the fixing block 41 fixed to the front end of the conveying beam 40 has a forwardly extending protrusion formed in the middle, and the top surface of the front end of the protrusion has an upwardly extending front limiting part. The bottom surface of the fiberglass board 1 to be processed presses against the top surface of the protrusion. The front sidewall of the fiberglass board 1 is close to or in close contact with the rear wall of the front limiting part, and the rear sidewall of the fiberglass board 1 is close to or in close contact with the front wall of the fixing block 41. The top surface of the protrusion corresponding to the central through hole of the fiberglass board 1 is formed with a central through groove. The left and right ends of the central through groove extend out of the left and right side walls of the protrusion. The left and right sides of the fiberglass board 1 are inserted into the side guide grooves of the side beam assembly extending forward and backward on the left and right sides of the conveying beam 40. The protrusion is inserted into the slot, and its left and right side walls are close to or in close contact with the inner sidewall of the slot. The conveying beam 40, side beam assembly and other components are components of the conveying mechanism, which can use existing conveying devices, and will not be described in detail here.

[0015] Furthermore, a vertical guide post 22 is fixed or installed on the lifting block 21, and the vertical guide post 22 is inserted into the vertical guide through hole formed in the middle of the left or right part of the first intermediate support block 14.

[0016] A guide sleeve 1410 is inserted into the vertical guide through hole. The radial annular portion formed on the bottom outer wall of the guide sleeve 1410 is inserted into the annular groove formed on the bottom inner wall of the vertical guide through hole. The outer wall of the guide sleeve 1410 is pressed against the inner wall of the vertical guide through hole. The vertical guide post 22 is inserted into the guide sleeve 1410, and its outer wall is close to or adjacent to the inner wall of the guide sleeve 1410.

[0017] The lower riveting post 211 is a column with a rectangular cross-section, and the lower vertical through hole 15 is a rectangular columnar through hole. The outer side wall of the lower riveting post 211 is close to the inner side wall of the lower vertical through hole 15, and the two are matched.

[0018] In this embodiment, the fiberglass board 1 to be processed is installed at the fixing block 41 of the conveying beam 40 and conveyed forward along the side guide grooves of the two side beam assemblies. When it is above the first intermediate support block 14, an aluminum rivet is inserted into the central through hole of the fiberglass board 1. The clamping head at the top of the aluminum rivet is located above the central part of the fiberglass board 1. At the same time, two welding plates are pressed against the top surface of the fiberglass board 1. The vertically extending downward edges formed at the four sides of the central through hole of the welding plates are inserted into the connecting through holes on the left and right sides of the fiberglass board 1, with their bottom ends extending out of the bottom end of the connecting through holes. At the same time, the fiberglass board 1 is connected by the connecting plate installed at the side beam assembly. When the proximity switch (not shown in the attached diagram) detects the contact, the push rods of the upper clamping cylinder 10 and the lower clamping cylinder 20 are pushed simultaneously, causing the bottom end of the upper riveting block 30 to press against the top surface of the welding piece and the top surface of the clamping head of the aluminum rivet, so that the bottom surface of the clamping head presses against the top surface of the fiberglass board 1, and the outer side wall of the top of the aluminum rivet presses against the outer side wall of the central through hole of the fiberglass board 1. At the same time, the bottom of the lower riveting column 211 pushes upward, and the four sides of the central through hole of the welding piece are opened and folded outward by the four-sided pyramidal riveting head 212, so as to achieve riveting fixation and complete the installation. The installation effect is good, the efficiency is high, and it is completed in one go.
