A placing fixture 44 for discharging and placing the single terminal 8 which has been riveted is installed on the second mounting plate 43.

[0042] The action principle of an automatic riveting machine for pipe fittings and terminals according to an embodiment of the present utility model is as follows:

[0043] S1: The terminal 8 on the terminal vibrating disk 10 is fed onto the linear feeding vibrator 11.

[0044] S2: First, the front one of the two blocking cylinders of the blocking assembly 23 drives to block. One terminal 8 on the linear feeding vibrator 11 is fed onto the single terminal picking station 21 of the assembling assembly line 2 and is blocked by the front one of the two blocking cylinders at the same time. At this time, the single picking sensor 22 senses the single terminal 8.

[0045] S3: Then, the first lifting module 242 on the dialing mechanism 24 drives the first lifting plate 244 to descend, so that the positioning rod 2461 on the first mounting plate 246 is inserted into the riveting hole 83 of the single terminal 8 at the single terminal picking station 21, and the first dialing block 2462 on the first mounting plate 246 abuts against the extension piece 81 of the single terminal 8.

[0046] S4: The front one of the two blocking cylinders of the blocking assembly 23 retracts to cancel the blocking, and the rear one of the two blocking cylinders drives to block, blocking the adjacent terminal 8 of the single terminal 8 at the single terminal picking station 21 to prevent it from entering the assembling assembly line 2 first.

[0047] S5: Then, the first linear transportation module 245 on the dialing mechanism 24 drives the first mounting plate 246 to come below the riveting station 26, so that the single terminal 8 reaches the riveting station 26.

[0048] S6: Next, the first lifting module 242 on the blank feeding mechanism 24 drives the first lifting plate 244 to rise. Then, the first linear transportation module 245 on the blank feeding mechanism 24 drives the first mounting plate 246 to retract. The rear cylinder of the two blocking cylinders retracts to cancel the blocking, and the front cylinder of the two blocking cylinders of the blocking assembly 23 drives to block. A terminal 8 on the linear feeding vibrator 11 is fed onto the single terminal picking station 21 of the assembly line 2);

[0049] S7: At the same time, the pushing cylinder 275 of the single pipe fitting picking mechanism 27 drives the single pipe fitting placement groove 277 on the single pipe fitting picking block 276 to the bottom of the pipe fitting feeding channel 279 (the pipe fitting feeding channel 279 is connected to the pipe fitting 9 bin, and the pipe fitting 9 bin is a prior art and not shown in the drawings). A pipe fitting 9 in the pipe fitting feeding channel 279 falls into the single pipe fitting placement groove 277. The pushing cylinder 275 of the single pipe fitting picking mechanism 27 drives the single pipe fitting placement groove 277 on the single pipe fitting picking block 276 to below the riveting station 26. Finally, the second lifting module 272 drives the second lifting plate 274 to rise, so that the single pipe fitting placement groove 277 on the single pipe fitting picking block 276 is aligned with the bottom of the single terminal 8 at the riveting station 26;

[0050] S8: Next, the linear pushing cylinder 281 of the lifting mechanism 28 drives the wedge-shaped pushing block 282 to abut against the roller 283 on the floating top block 284, so that the floating top block 284 slides and rises below the riveting station 26 of the assembly line 2. As a result, the lifting rod 285 on the floating top block 284 passes through the single pipe fitting placement groove 277. Finally, the lifting rod 285 pushes the pipe fitting 9 into the riveting hole 83 of the terminal 8 and into the optimal riveting height position;

[0051] S9: The riveting head 291 of the riveting mechanism 29 rivets the pipe fitting 9 and the terminal 8;

[0052] S10: After the riveting is completed, the single pipe fitting picking mechanism 27, the lifting mechanism 28, and the riveting mechanism 29 are reset. During the process that the blank feeding mechanism 24 in step S6 feeds the next single terminal 8 from the single terminal picking station 21 to the riveting station 26, incidentally, the second block 2463 of the blank feeding mechanism 24 feeds the already riveted terminal 8 into the discharging line 3;

[0053] S11: The discharging pipeline 3 is a linear vibrator. The discharging pipeline 3 moves the already riveted terminals 8 to one end. The second linear transportation module 41 of the single discharging mechanism 4 drives the second mounting plate 43 close to the discharging pipeline 3, so that the placement jig 44 abuts against one end of the discharging pipeline 3, thereby putting a single already riveted terminal 8 into the placement jig 44. Finally, the single discharging mechanism 4 moves the placement jig 44 away to facilitate taking by the next workstation or manually.

[0054] The above-mentioned first lifting module 242, first linear transportation module 245, second lifting module 272, and second linear transportation module 41 in the embodiments of the present invention are a slide table or a cylinder or a combination of a cylinder and a slide rail slider or a combination of a rotary motor, a synchronous pulley and a synchronous belt, a slide rail slider or a combination of a rotary motor, a lead screw, and a slide rail slider or other driving components that are driven in a linear form.

[0055] An automatic riveting machine for pipe fittings and terminals in the embodiments of the present invention can realize the automatic riveting of terminals 8 and pipe fittings 9, with high riveting accuracy, high yield rate, high production efficiency, and greatly reducing the labor intensity of workers.

[0056] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
