The utility model discloses each technical feature in the creation can the interactive combination under the prerequisite that does not contradict conflict each other.
Referring to fig. 1 and 2, the numerical control press riveting machine head capable of preventing hand pressing comprises an upper die holder 1, a lower die holder 2, a pressing die 3 and a control system, wherein the pressing die 3 is arranged at the bottom of the upper die holder 1, the pressing die 3, the upper die holder 1 and the lower die holder 2 are electrically communicated through contact, and the hand pressing riveting process is realized through electrical communication; the upper die base 1 is further provided with an upper die connecting piece 4, the upper die connecting piece 4 is further provided with a pressing hand detection structure, and the pressing hand detection structure is used for preventing pressing detection during pressing riveting. The hand pressing detection structure comprises a proximity switch 5, the proximity switch 5 is a photoelectric sensor, when the proximity switch 5 is in a space of a shell surrounding of the upper die base 1, the photoelectric sensor sends a signal for normal riveting, and when the photoelectric sensor is not shielded, if the photoelectric sensor slides to a clearance position 6, the photoelectric sensor sends an error signal for riveting to a control system. The proximity switch 5 is arranged on the upper die connecting piece 4, the upper die base 1 is further provided with a clearance position 6, and the proximity switch 5 and the clearance position 6 are correspondingly arranged.
The specific riveting process comprises the following steps: there is the safe potential difference of 5V between riveter upper die, material pressing grinding apparatus and the lower mould to form a closed circuit, the material pressing grinding apparatus divide into upper die and lower mould, and the upper die sets up in upper die base 1 bottom, and the lower mould sets up on lower die base 2. When the upper die, the workpiece and the lower die are in complete contact, two working conditions can occur: one condition is that when the workpiece is a metal/conductor, the 5V closed circuit among the upper die, the workpiece and the lower die is switched on, the normally open relay arranged at the control system is closed, and the relay transmits a correct command to the control system. Under the state that closed circuit intercommunication, photoelectric sensor signal is normal, and upper die base 1 drives the mould and continues to push down at this moment and accomplish the pressure and rivet the action. The other condition is that the workpiece is a hand/insulator, at this time, because the hand or the insulator cannot be normally electrified, a 5V closed circuit between the upper die, the workpiece and the lower die is still disconnected, at this time, a control system does not obtain a correct command for closing the relay, when the photoelectric sensor on the upper die connecting piece 4 continuously presses down for 3mm in the upper die base 1 to the clearance position 6, the photoelectric sensor sends an error signal and transmits the command to the control system, the control system executes the next procedure (namely, the electro-hydraulic servo valve is closed), at this time, the hand pressing prevention device integrally ascends, the pressing head is separated from the hand/insulator, and the hand is prevented from being mechanically damaged.
Referring to fig. 3 and 4, specifically, for the upper die holder 1 and the upper die connecting piece 4 which are arranged in a sliding manner, an installation groove 11 is formed in the upper die holder 1, the upper die connecting piece 4 is located in the installation groove 11, and the upper die connecting piece 4 is arranged in the installation groove 11 in a sliding manner.

Just can push down the slip in the mounting groove 11 of upper die base 1 after last mould connecting piece 4 receives the drive of drive structure, along with the pushing down of connecting piece, upper die base 1 receives the pressure that comes from last mould connecting piece 4 can be promoted downwards to the last mould that drives the material grinding apparatus pushes down and presses the riveting. And the upper die holder 1 and the upper die connecting piece 4 can be simultaneously subjected to the elastic force of the spring 12 in the process of pressing the upper die connecting piece 4 downwards, so that elastic buffering is realized when the upper die connecting piece is pressed to the position of the spring 12, and the impact force generated by direct press riveting is reduced.
To preventing pressing the hand and detecting the structure, keep away empty position 6 and set up the side at upper die base 1, and be the logical groove on the side of upper die base 1 and the 11 intercommunications of mounting groove, proximity switch 5 sets up the side at last mould connecting piece 4, and is located the position that corresponds with keep away empty position 6 on the slider of last mould connecting piece 4. Like this, when going up mould connecting piece 4 and pushing down, proximity switch 5 that sets up on last mould connecting piece 4 just can follow last mould connecting piece 4 and slide down in the mounting groove 11 of upper die base 1, when proximity switch 5 slided down to the clearance position 6 that upper die base 1 side was seted up, proximity switch 5 just can produce the signal. The distance of the downward pressing buffer stroke of the upper die connecting piece 4 in the mounting groove 11 of the upper die holder 1 is about 10mm, so that the system can reserve enough time for judgment after receiving the output signal of the proximity switch 5. When the riveting is carried out, the upper die and the lower die are in butt joint, the middle part is a metal conducting plate, the conducting condition is achieved, and the proximity switch 5 is set to be the output signal 1 and is output to the control system to be the judgment condition. When the upper die connecting piece 4 is continuously pressed down in the mounting groove 11, the metal upper die base 1 shell exceeds the induction line of the proximity switch 5, and the proximity switch 5 generates an output signal 2. And the system receives the output signal 1, judges that the continuous pressing condition is met after outputting the signal 2, continuously presses the upper die, and starts to generate pressure after the buffer distance is finished.
