Detailed Description
The invention is described in further detail below with reference to the accompanying drawings.
As shown in fig. 1, a column type riveting module for riveting corner points of a refrigerator liner is used for riveting corners between a bottom plate and a coaming of the refrigerator liner, and comprises a first column 310 and a second column 311. The first and second columns 310 and 311 are vertically disposed and fixed to each other by a connection block 314. The second upright 311 is provided with two rivet means facing the first upright 310: a rivet device 312 for horizontal corner riveting and a rivet device 313 for vertical corner riveting. The first upright 310 is provided with a right angle spacer co-located with the clinching device. The two riveting devices respectively correspond to the right-angle cushion blocks. The right-angle cushion block is used for providing right-angle support for the riveting device when riveting the side angle nails.
The rivet devices 312, 313, as shown in fig. 2, 3, 4, 5, 6, 7, 8, and 9, include a translation stage base plate 32, a translation stage 33, a translation cylinder 331, a rivet swing stage 34, a swing drive stage 35, and a swing cylinder 351. The pan carriage base plate 32 is mounted on the second upright 311. The translation frame base plate 32 is provided with a clamping groove. The translation frame 33 is caught on the catching groove so that the translation frame 33 can move forward and backward on the translation frame base plate 32. The clamping groove on the translation frame bottom plate 32 is constructed by two L-shaped sliding guide plates 321 reversely buckled on two sides of the translation frame bottom plate 32 and a straight guide clamping plate 322 arranged between the two L-shaped sliding guide plates 321. The two L-shaped sliding guide plates 321 are bilaterally symmetrical and parallel to each other. A wing groove 323 is formed between the L-shaped sliding guide plate 321 inversely fastened to the pan frame base plate 32 and the pan frame base plate 32. The flat guide clamping plate 322 is mounted on the translation frame bottom plate 32 and is positioned in the middle of the two L-shaped sliding guide plates 321. Two sliding channels 324 are respectively formed between the flat guiding clamping plate 322 and the two L-shaped sliding guiding plates 321. The translation frame 33 is a block, and a clamping block 332 matched with a clamping groove on the bottom plate 32 of the translation frame is arranged at the bottom. Wing protrusions 3321 are arranged on two sides of the clamping block 332, and a straight guiding clamping groove 3322 is arranged in the middle of the bottom. The two wing protrusions 3321 at two sides of the fixture block 332 are respectively corresponding to and matched with the two wing grooves 323. The straight guide card slot 3322 corresponds to and mates with the straight guide card 322. Thus, the translation frame 33 is locked to the translation frame bottom plate 32 by the engagement of the locking groove on the translation frame bottom plate 32 and the locking block 332 at the bottom of the translation frame 33, and can move back and forth along the locking groove. A limiting block 325 is arranged at the rear of the clamping groove.
The rear end of the translation frame 33 is connected to the piston of the translation cylinder 331. The translation cylinder 331 is disposed in the front-rear direction and is mounted on the translation frame base plate 32. The rear end of the translation cylinder 331 is fixed to the cylinder backplate 329. The cylinder back 329 is vertically mounted on the pan carriage floor 32. The translation cylinder 331 is used for driving the translation frame 33 to move back and forth on the translation frame base plate 32. A guide plate 335 is installed at the front end of the translation frame 33. A step groove 333 is provided above the front end surface of the translation frame 33. The guide plate 335 is mounted on the step groove 333 of the translation frame 33 by a guide mounting frame 3351. The front end surface of the guide plate 335 is provided with a guide inclined surface 3352 inclined forward and backward, and the bottom is used as a riveting pad surface during riveting. Rivet holes 3353 are provided on the rivet pad surface. Swing shaft holes 334 are provided on both sides of the front end of the translation frame 33.
The rivet swing frame 34 includes a swing plate 341 and a rivet frame plate 345. There are two swinging plates 341. The two swinging plates 341 are respectively erected on two sides of the translation frame 33 through a swinging shaft 342 and a swinging shaft hole 334. The two ends of the rivet plate 345 are respectively fixed to the two swing plates 341 and perpendicular to the swing plates 341. The rivet plate 345 is located in front of the translation frame 33 and below the guide plate 335. The rivet plate 345 has a platen surface 3451. The platen surface 3451 is provided with rivet 346. The positions of the rivet 346 are matched with the positions of the rivet holes 3353 at the bottom of the guide plate 335. The upper end of at least one of the two swing plates 341 is provided with a driving block 343.
The swing driving frame 35 is provided above the translation frame 33 and is connected to the swing cylinder 351 such that the swing driving frame 35 can be moved forward and backward with respect to the translation frame 33 by the driving of the swing cylinder 351. The front end of the swing driving frame 35 is provided with a driving plate 352. In this embodiment, in consideration of space allowance, the rivet device 312 for horizontal corner riveting and the rivet device 313 for vertical corner riveting adopt different mounting modes of the swing cylinder 351: in the rivet device 312 for riveting horizontal corners, as shown in fig. 2, 3 and 5, a swing cylinder 351 is stacked on a translation cylinder 331, the rear end is fixed to a cylinder back plate 329, and a front end piston of the swing cylinder 351 is connected to the rear end of a swing driving frame 35. In the rivet device 313 for vertical corner riveting, as shown in fig. 8 and 9, the swing driving frame 35 and the driving plate 352 constitute a four-square frame structure; the swing cylinder 351 is provided in the square frame structure and is fixed to the translation frame 33, and the rear end piston is connected to the rear end of the swing drive frame 35. The drive plate 352 protrudes to the side of the swing drive frame 35. When the swing driving frame 35 moves back and forth, the protruding portion of the side edge of the driving plate 352 can prop against the front end of the driving block 343 of the rivet swing frame 34, and therefore the rivet swing frame 34 is driven to swing around the swing shaft 342 in a turnover manner through the driving block 343. When the rivet swing frame 34 swings upside down, the rivet frame plate 345 is driven to swing upwards, and the pressing plate surface 3451 on the rivet frame plate 345 can be pressed on the bottom surface of the guide plate 335, so that the edge pressing and rivet operation are completed. At this time, the rivet 346 on the pressing plate surface 3451 is driven into the rivet hole 3353 at the bottom of the guide plate 335.
The working principle of the edge pressing and riveting operation is shown in fig. 12. Wherein 391 is a floor, typically a Z-shaped floor; 392 is a bottom plate crimping; 393 is the coaming, namely the oral coaming or the big coaming and the small coaming which form the oral coaming; 394 is a coaming flange. The bottom plate bending edge 392 and the coaming bending edge 394 are both 90-degree bends. The bottom plate 391 is perpendicular to the coaming 393, and the bottom plate 391 is perpendicular to the coaming 393 at the corners through the right-angle cushion 399. First, in the initial state of the riveting device, the pressing plate surface 3451 on the riveting plate 345 is separated from the bottom surface of the guide plate 335, and a gap of 6-12 mm is formed, which is smaller than the bending width of the bottom plate bending edge 392. Then, the coaming bending edge 394 is snapped into the bending angle formed by the base plate bending edge 392 by the transfer of the robot plate and the outward bracing action of the first upright 310. Then, the translation cylinder 331 drives the translation frame 33 to move forward, so that the coaming bending edge 394 is clamped into the structure formed by the bending angle formed by the bottom plate bending edge 392 under the guidance of the guiding inclined surface 3352 of the guiding plate 335 at the front end of the translation frame 33, and is clamped into the gap between the pressing plate surface 3451 on the rivet frame plate 345 and the bottom surface of the guiding plate 335. At this time, since the width of the bottom plate bent edge 392 is larger than the gap between the pressing plate surface 3451 on the rivet plate 345 and the bottom surface of the guide plate 335, after the bottom plate bent edge 392 is caught in the gap, the bottom plate bent edge 392 is bent into an acute angle mechanism by 90 degrees by the pressing plate surface 3451 on the rivet plate 345. Thus, when the floor flange 392 is snapped into the gap, it overlaps the shroud flange 394 into the gap. At this time, the guide plate 335 is required to be clamped on the right-angle pad 399, otherwise, the bottom plate bending edge 392 and the coaming bending edge 394 are likely to be not overlapped to be clamped into the gap, but the middle of the bottom plate is raised. Then, the swing cylinder 351 drives the rivet swing frame 34 to turn over, and drives the rivet frame plate 345 to swing upwards, so that the pressing plate surface 3451 on the rivet frame plate 345 can be pressed on the bottom surface of the guide plate 335, thereby pressing together the parts of the coaming folded edge 394, the bottom plate folded edge 392 and the bottom plate 391, which are more than the right-angle cushion block 399, and simultaneously riveting together the parts of the coaming folded edge 394, the bottom plate folded edge 392 and the bottom plate 391, which are more than the right-angle cushion block 399, through the nailing of the riveting nails 346. After the caulking is completed, the rivet swing frame 34 is reset to an initial state, and the pressing plate surface 3451 on the rivet frame plate 345 is separated from the bottom surface of the guide plate 335.
In the above process, the reset of the rivet swing frame 34 to the initial state is achieved by the rivet reset mechanism. The rivet resetting mechanism is used for resetting the rivet swing frame 34. After the rivet swing frame 34 is reset, the pressing plate surface 3451 on the rivet frame plate 345 is separated from the bottom surface of the guide plate 335. The gap between the pressing plate surface on the separated rivet support plate and the bottom surface of the guide plate is 6-12 mm. In this embodiment, three embodiments are adopted for the rivet resetting mechanism:
in the first embodiment, in the rivet device 312 for horizontal corner riveting, since the weight of the rivet plate 345 on the rivet swing frame 34 is relatively large, in this embodiment, the rivet plate 345 can naturally swing down by the gravity action of the weight of the rivet plate 345 on the rivet swing frame 34, thereby achieving resetting. At this time, the rivet resetting mechanism is a rivet plate 345 of a large weight.
A second embodiment may be to provide a return spring 336 between the rivet swing frame 34 and the translating frame 33. The rivet swing frame 34 is reset by the elasticity of the reset spring 336.
In the third embodiment, in the rivet device 313 for vertical corner riveting, the swing driving frame 35 is provided with a reset lever 353. The reset lever 353 is located at the rear side of the driving block 343. When the swing driving frame 35 moves, the reset rod 353 can prop against the rear end of the driving block 343, and the swing cylinder 351 pushes the rivet swing frame 34 to reset.
The right angle spacer 399 is necessary according to the operating principles of the above-described crimping and riveting operations. The right angle spacer 399 plays a role of right angle support. If the edge is an arc corner, the problem of abdication of the plate material at the riveting edge line part during riveting can occur. Because the width of the riveting edge line part is very small and is generally not more than 15 mm, the problem of yielding of the plate material of the riveting edge line part during riveting can directly cause riveting failure. For this purpose, in the present embodiment, as shown in fig. 1 and 10, the top of the first pillar 310 is provided with a right angle pad 315. The first pillar 310 itself is a pillar of L-shaped cross section. The clinching means 312 for horizontal corner clinching is opposite the first upright 310. The corner of the right-angle pad 315 in the direction of the riveting device for riveting the horizontal corner is a right-angle corner, thereby realizing the function of the right-angle pad 399. The guide plate 335 of the rivet device 312 can be snapped onto the right angle shim plate 315 as the translation carriage 33 moves forward. Similarly, the rivet device 313 for vertical corner riveting also requires a corresponding right angle spacer. In this embodiment, the joint between the two flat plates of the L-section column of the first column 310 has an arc-shaped corner 319. The arc-shaped corners 319 of the first upright post 310 facilitate the loading and unloading of the port-shaped coaming. However, in the riveting of the vertical corners of the Z-shaped bottom plate, the corners opposite to the riveting device 313 requiring the riveting of the vertical corners are right-angle corners. For this reason, in this embodiment, as shown in fig. 1, 10 and 11, a right-angle block 362 driven by an air cylinder to stretch out and draw back is provided at an arc-shaped corner 319 facing the front end of the rivet device. The right angle block 362 is installed in the telescopic hole of the arc-shaped corner 319 of the first upright 310 and is connected to the telescopic cylinder 361. The telescopic cylinder 361 is mounted inside the column of the L-shaped section by a corner bracket 363. The expansion direction of the expansion cylinder 361 is 45 degrees with two flat plates of the column body with the L-shaped section. Therefore, when riveting, the right-angle block 362 extends out under the driving of the telescopic cylinder 361, so as to realize the function of the right-angle cushion block 399. When loading and unloading, the right angle block 362 is retracted, so that loading and unloading are not hindered.
It should be noted that in this embodiment, the column type riveting module includes two riveting devices. It will be appreciated by those skilled in the art that the post-rivet module may also include only rivet means 312 for horizontal corner riveting and not rivet means 313 for vertical corner riveting, or may also include only rivet means 313 for vertical corner riveting and not rivet means 312 for horizontal corner riveting. How the top riveting device on the column type riveting module is configured is designed according to an actual production line, for example, in the riveting operation of a flat bottom plate and a port-shaped coaming, the riveting device 313 for riveting vertical corners is not needed.
