[0034] Specific operation is as follows, the actual interval between laser sensor 602 and insertion port 4 is fixed, after rod body 501 is inserted into insertion port 4, artificial holds handle 2 and inserts deformation cap 502 into the workpiece hole position needing riveting, at this time, one side of patch 503 is abutted against the end of insertion port 4, and the other side is abutted against the surface of workpiece, and the thickness of patch 503 is also measured in advance, so that laser sensor 602 measures the interval between itself and the surface of workpiece at this time, the interval between laser sensor 602 and insertion port 4 is set as A, the interval between laser sensor 602 and the surface of workpiece is B, and the thickness of patch 503 is C, if B-A is greater than C, it indicates that deformation cap 502 is not inserted into the position by artificial, at this time, riveting will cause unstable connection between workpieces, so as to trigger alarm to prompt, if B-A is equal to C, it indicates that deformation cap 502 is inserted into the position by artificial, and then riveting is carried out;
[0035] When riveting, air pump box 1 injects external air into the inside of support rod 11 along pipeline and air inlet pipe 14, so that telescopic claw sheet 12 is close to each other to clamp rod body 501, and then air pump box 1 also injects external air into the inside of air cylinder 7 along another pipeline and first air port 8, so that piston rod 10 is retracted into the inside of air cylinder 7, so that rod body 501 is deformed under the action of external pulling, until rod body 501 is broken, so as to complete riveting and fixing of workpiece;
[0036] And the self-checking sheet 604 is manually rotated to rotate to the front of the laser sensor 602 through the damping rotating ring 603 regularly or each time the laser sensor 602 is started, since the distance between the laser sensor 602 and the self-checking sheet 604 is always fixed, thus the distance between the laser sensor 602 and the self-checking sheet 604 is measured after the laser sensor 602 is started, whether the measured distance is consistent with the actual distance, thus the laser sensor 602 is self-checked, if the measured distance is consistent with the actual distance, it indicates that the laser sensor 602 is accurate, if not, it indicates that the laser sensor 602 has an error, at this time, manual calibration is needed, thus the pull riveting accuracy is ensured;
[0037] Based on the above description, when the pull riveting gun is manually held to perform pull riveting, the thickness of the patch 503 and the distance between the laser sensor 602 and the insertion opening 4 are known data, and then the distance between the laser sensor 602 and the workpiece surface during pull riveting is measured, if the sum of the known data is consistent with the distance between the laser sensor 602 and the workpiece surface, it indicates that the deformed cap 502 of the rivet is inserted in place, if the sum of the known data is less than the distance between the laser sensor 602 and the workpiece surface, it indicates that the deformed cap 502 is not inserted in place, at this time, continuous pull riveting will cause the workpiece to be not fastened in place and loose, at this time, an alarm is issued to stop subsequent pull riveting, thus prompting the personnel to re-adjust the deformed cap 502 of the rivet, thereby facilitating the timely avoidance of the generation of loose workpieces.
[0038] Moreover, the data measured by the laser sensor 602 can be actively self-checked, only the self-checking sheet 604 needs to be manually rotated to be located on the distance measuring path, since the distance between the laser sensor 602 and the self-checking sheet 604 is a known parameter, if the parameter measured by the laser sensor 602 is consistent with the known parameter, it indicates that the laser sensor 602 is accurate and can participate in pull riveting, if not, it is timely prompted that manual calibration is needed, thus avoiding that the laser sensor 602 has an error and participates in pull riveting to cause the workpiece to be not fastened in place.
[0039] As shown in Figures 1-6 The outer wall bottom of the gun body shell 3 is provided with a recycling assembly 15, the recycling assembly 15 comprises a plug-in sleeve 1501, the inside of the plug-in sleeve 1501 is provided with a falling channel, and the falling channel is in communication with the inside of the gun body shell 3, the recycling assembly 15 further comprises a recycling sleeve box 1502, the outer wall bottom of the plug-in sleeve 1501 is sleeved with the recycling sleeve box 1502, the recycling assembly 15 further comprises a magnet box 1503, the outer wall bottom of the recycling sleeve box 1502 is sleeved with the magnet box 1503, the magnet box 1503 is plug-in connected with the recycling sleeve box 1502, and the recycling sleeve box 1502 is plug-in connected with the plug-in sleeve 1501;
[0040] The specific operation is as follows: the rod body 501 is broken due to the applied tension force, and the broken rod body 501 is located inside the gun body shell 3 and above the falling channel. At this time, the electronic valve at the exhaust pipe 13 is opened to exhaust air, so that the telescopic claw 12 is away from each other to loosen the rod body 501, and the rod body 501 falls along the falling channel to the inside of the recycling sleeve box 1502. The falling channel inside is provided with a counting sensor for recording the number of recycled rod bodies 501. A set of fixed number of rod bodies 501 is preset to represent a workpiece after the rivet is fixed. Based on the number of rod bodies 501 in the recycling sleeve box 1502, the number of rivet workpieces is recorded. When the rod body 501 is stored in the recycling sleeve box 1502, the magnet box 1503 is used to adsorb it to prevent the rod body 501 from shaking randomly and making noise. When the rod body 501 in the recycling sleeve box 1502 is removed, the recycling sleeve box 1502 is pulled down and inverted, and the magnet box 1503 is pulled up. When the magnetic adsorption effect of the magnet box 1503 is lost, the rod body 501 automatically falls under the action of gravity.
[0041] After the rod body 501 falls, air is injected into the second air port 9 to make the piston rod 10 extend and reset, so as to enter the next rivet cycle.
[0042] Based on the above description, the present application does not need manual operation to make the insertion port 4 downward to exit the rod body 501 after each riveting. After riveting each time, the telescopic claw 12 is loosened after the rod body 501 is broken, so that the rod body 501 naturally falls into the recycling sleeve box 1502. Only a certain amount of rod body 501 needs to be stored in the recycling sleeve box 1502, and then it can be removed for centralized cleaning. The degree of complexity of the riveting gun is greatly reduced. Moreover, the rod body 501 is adsorbed by the magnet box 1503 after entering the recycling sleeve box 1502 to prevent the rod body 501 from shaking randomly and making noise during riveting.
[0043] A control method applied to the above-described error-proof riveting gun, the control method comprising the following steps:
[0044] Step one: manually rotate the self-checking sheet 604 to rotate to the front of the laser sensor 602 through the damping rotating ring 603. Since the distance between the laser sensor 602 and the self-checking sheet 604 is always fixed, the distance between the laser sensor 602 and the self-checking sheet 604 is measured after the laser sensor 602 is started, so as to self-check the laser sensor 602;
[0045] Step two: after the laser sensor 602 self-checks, rotate the self-checking sheet 604 so that it no longer blocks the laser sensor 602. The actual distance between the laser sensor 602 and the insertion port 4 is fixed. After the rod body 501 is inserted into the insertion port 4, manually hold the handle 2 to push the deformation cap 502 into the workpiece hole position that needs to be riveted. At this time, one side of the patch 503 is against the end of the insertion port 4, and the other side is against the workpiece surface. The thickness of the patch 503 is also pre-measured. Therefore, at this time, the laser sensor 602 measures the distance between itself and the workpiece surface. The distance between the laser sensor 602 and the insertion port 4 is set as A, the distance between the laser sensor 602 and the workpiece surface is set as B, and the thickness of the patch 503 is set as C. If B-A is greater than C, it indicates that the deformation cap 502 is not pushed in place by the artificial, and riveting at this time will cause unstable connection between the workpieces, thereby triggering the alarm to prompt. If B-A is equal to C, it indicates that the deformation cap 502 is pushed in place by the artificial, and then riveting is performed.
[0046] Step three: during riveting, the air pump box 1 injects external air into the inner part of the branch rod 11 along the pipeline and the air inlet pipe 14, so that the telescopic claw sheet 12 approaches each other to clamp the rod body 501. Then the air pump box 1 also injects external air into the inner part of the air cylinder 7 along another pipeline and the first air port 8, so that the piston rod 10 retracts into the air cylinder 7. Thus, the rod body 501 deforms the deformation cap 502 under the action of external pulling, until the rod body 501 breaks, thereby completing the riveting and fixing of the workpiece.
[0047] Step four: the broken rod body 501 is located in the inner part of the gun body shell 3 and above the falling channel. At this time, the electronic valve at the exhaust pipe 13 is opened to exhaust air, so that the telescopic claw sheet 12 moves away from each other to release the rod body 501. The rod body 501 falls along the falling channel to the inner part of the recycling sleeve box 1502. The falling channel inside is provided with a counting sensor for recording the number of recycled rod bodies 501. A fixed number of rod bodies 501 is set as a completed riveted workpiece. Based on the number of rod bodies 501 in the inner part of the recycling sleeve box 1502, the number of riveted workpieces is recorded.
[0048] Step five: when storing the rod body 501 in the recycling sleeve box 1502, use the magnet box 1503 to adsorb it to prevent the rod body 501 from shaking randomly and making noise. When removing the rod body 501 in the recycling sleeve box 1502, just pull down the recycling sleeve box 1502 and invert it, and pull up the magnet box 1503. When the magnetic attraction of the magnet box 1503 is lost, the rod body 501 automatically falls under the action of gravity.
