Description

[0001] The invention relates to the field of rivet installation equipment, and in particular to an automatic rivet installation equipment in a mold. Background Art

[0002] In the existing automotive mold field, when installing rivets on the mold, most of the work is done manually, and the rivets need to be placed manually one by one in the appropriate position in the mold. This will greatly rely on manual operation, and the human operation speed is relatively slow. In the large-scale production process, manual installation of rivets will become a bottleneck in the production process, slowing down the entire production rhythm. For example, in an automobile manufacturing workshop, if workers manually install rivets for connecting body parts, compared with automated installation, the production efficiency may be reduced by several times or even more.

[0031] The preferred embodiments of the present invention are now further described in conjunction with the accompanying drawings. Figures 1 to 3 As shown, an automatic installation device for rivets in a mold includes a workbench 10, on which a first conveying mechanism 100 is arranged in a preset direction, a supporting plate 110 is placed on the top of the first conveying mechanism 100, and a mold 20 on which rivets need to be installed is placed on the supporting plate 110, and a hole position calibration mechanism 200 and a rivet installation mechanism 300 are sequentially arranged along the movement direction of the first conveying mechanism 100, and the hole position calibration mechanism 200 and the rivet installation mechanism 300 are respectively arranged on both sides of the first conveying mechanism 100, the hole position calibration mechanism 200 is used to position the rivet holes 22 on the side walls of the mold 20, and the rivet installation mechanism 300 is used to drive the rivets into the rivet holes 22.

[0032] In the working state of this embodiment, the mold 20 is first placed on the supporting plate 110, and then the first conveying mechanism 100 drives the supporting plate 110 to move along the preset direction to the middle of the hole position calibration mechanism 200, and then the hole position calibration mechanism 200 is started to position and calibrate the nail holes 22 on the side walls of the mold 20. After completion, the first conveying mechanism 100 is started again to drive the supporting plate 110 to move along the preset direction again to the middle of the rivet installation mechanism 300, and then the rivet installation mechanism 300 is started to drive the rivets into the nail holes 22.

[0033] Compared with the prior art, the present application uses a first conveying mechanism 100 and a hole position calibration mechanism 200 and a rivet installation mechanism 300 sequentially arranged along the movement direction of the first conveying mechanism 100, so that when installing the rivets, it is only necessary to place the mold 20 on the supporting plate 110, and the subsequent hole position calibration and rivet installation are all completed automatically, which greatly improves the production efficiency and yield rate.

[0034] On the basis of the above embodiments, Figure 3 As shown, the first conveying mechanism 100 includes a first guide rail 120, and a first sliding seat 130 and a first driving motor 140 are respectively arranged on the top and one end of the first guide rail 120, and the first driving motor 140 is used to drive the first sliding seat 130 to slide along the first guide rail 120, and the supporting plate 110 is fixed on the top of the first sliding seat 130. When the mold 20 is placed on the supporting plate 110, the first driving motor 140 is started to drive the first sliding seat 130 and the supporting plate 110 to move along the first guide rail 120.

[0035] On the basis of the above embodiments, Figure 4 As shown, the hole position calibration mechanism 200 includes a second guide rail 210, and the laying direction of the second guide rail 210 is perpendicular to the first guide rail 120. A second sliding seat 220 and a first driving cylinder 230 are arranged on the second guide rail 210. The driving end of the first driving cylinder 230 is connected to the second sliding seat 220. When the first driving cylinder 230 is started, the second sliding seat 220 can be driven to move along the second guide rail 210. A first connecting frame 240 is installed on the second sliding seat 220, and a plurality of positioning rods 250 are arranged on the top of the first connecting frame 240. When the first driving motor 140 drives the supporting plate 110 to move with the mold 20 to between the hole position calibration mechanism 200, the first driving cylinder 230 is started to drive the second sliding seat 220 to move along the second guide rail 210, thereby driving the positioning rod 250 to insert into the nail hole 22 on the side wall of the mold 20, thereby forming a positioning for the nail hole 22.

[0036] In some embodiments, Figure 5 As shown, the positioning rod 250 includes a cylindrical rod body 251, and a step portion 251a is provided on the side of the rod body 251 close to the mold 20, which is recessed into the rod body 251. The step portion 251a forms a raised step end 251b on the rod body 251, and a guide groove 251c is provided on the step portion 251a along the direction of the rod body 251. A positioning sleeve 252 is sleeved on the step portion 251a, and the rod body 251 can be extended into or extended from the positioning sleeve 252. First through holes 252a are provided on opposite sides of the positioning sleeve 252, and a guide rod 253 is provided in the positioning sleeve 252. When the positioning sleeve 25 When the rod body 251 is arranged, the guide rod 253 passes through the first through hole 252a and the guide groove 251c, and a spring 254 is arranged between the step end 251b and the positioning sleeve 252. When the positioning rod 250 is driven to insert into the nail hole 22 on the side wall of the mold 20, the positioning sleeve 252 abuts against the side walls around the nail hole 22, and the rod body 251 passes through the positioning sleeve 252 and extends into the nail hole 22 to position the nail hole 22. In this process, the positioning sleeve 252 retreats along the guide groove 251c so that the retreat direction does not deviate, and the spring 254 is compressed to prevent the positioning sleeve 252 from excessively abutting against the side walls around the nail hole 22 and causing damage to the side walls.

[0037] On the basis of the above embodiments, Figure 6 As shown, the rivet installation mechanism 300 includes a third guide rail 310 arranged in parallel, and the laying direction of the third guide rail 310 is perpendicular to the first guide rail 120.

A second connecting frame 340 is installed on the third sliding seat 320, and a rivet installation device 350 is installed on the second connecting frame 340. When the first driving motor 140 drives the supporting plate 110 to move with the mold 20 from between the hole calibration mechanisms 200 to between the rivet installation mechanisms 300, the second driving cylinder 330 is started to drive the third sliding seat 320 to move along the third guide rail 310, thereby driving the rivet installation device 350 to drive the rivet into the rivet hole 22.

[0038] On the basis of the above embodiments, Figure 6 and Figure 7As shown, the rivet installation device 350 includes a rivet shooting part 351 and a rivet shooting part 352. A hollow first clamping end 353 is provided at one end of the rivet shooting part 352. The first clamping end 353 is aligned with the outlet of the rivet shooting part 351. A fourth guide rail 354 is connected to the other end of the rivet shooting part 352. A third driving cylinder 355 is provided on one side of the fourth guide rail 354. The third driving cylinder 355 is connected to the rivet shooting part 352. When the third driving cylinder 355 is activated, the rivet shooting part 352 can be driven. The movable rivet portion 352 moves along the fourth guide rail 354. When the rivet installation device 350 abuts against the rivet hole 22, the first clamping end 353 is aligned with the rivet hole 22, and then the rivet shooting portion 351 is controlled to shoot the rivet through the first clamping end 353 and shoot the rivet into the rivet hole 22. At this time, the first clamping end 353 clamps the end of the rivet, and then the third driving cylinder 355 is started, thereby driving the rivet portion 352 to move in the opposite direction along the fourth guide rail 354, thereby tightening the rivet in the rivet hole 22.

A second connecting plate 470 is provided at the bottom of the lifting cylinder 460, and a clamping cylinder 480 and a second clamping end 490 are provided at the bottom of the second connecting plate 470. The clamping cylinder 480 is used to control the opening and closing of the second clamping end 490. When the mold 20 completes the installation of the rivet, the fourth driving cylinder 440 drives the fourth sliding seat 430 to move along the fifth guide rail 420 to the top of the mold 20, and then the first lifting cylinder 460 controls the clamping cylinder 480 and the second clamping end 490 to descend to a preset height, so as to control the second clamping end 490 to clamp the mold 20 and thus the support plate 110 and transport it to the next process.

[0041] In some embodiments, in combination Figure 2 and Figure 8 As shown, a through slot 21 is provided on the mold 20. When the second clamping end 490 is lowered and opened to both sides, it extends into both sides of the through slot 21, so that the mold 20 can be clamped upward more conveniently.
