[0036] like Figure 2 As shown in the figure, X refers to the X-axis in the coordinate system, Y refers to the Y-axis in the coordinate system, and Z refers to the Z-axis in the coordinate system.

[0037] like Figure 1 As shown, the present invention provides a riveted nut processing device, including a vibration plate 1, the outlet of the vibration plate 1 is connected to a nut channel 2, and the nut channel 2 is connected to a plurality of tooling stations 4, and the nuts falling on the tooling stations 4 are transferred to the auxiliary component 3 by a transfer component 5.

[0038] The nuts are fed by the vibration plate 1, and then the nuts are delivered to the tooling station 4 from the nut channel 2, and then the nuts are transferred to the auxiliary component 3 by the transfer component 5, and then the nuts are pre-punched.

[0039] Please focus on Figure 2 and Figure 3 The nut channel 2 includes a main channel 201, and a plurality of feeding grooves are arranged in the main channel 201. The number of the feeding grooves is equal to the number of the tooling stations 4. A branch channel 202 is arranged corresponding to the position of the tooling station 4. The branch channel 202 is used to connect the feeding groove and the tooling station 4. At the same time, the feeding groove of the main channel 201 and the groove of the branch channel 202 are both installed with a cover plate 203 to prevent the nut from shifting and falling when discharging.

[0040] First, the nuts are discharged from the vibration plate 1 , move along the main channel 201 to the branch channel 202 , and then move to the tooling station 4 .

[0041] Please focus on Figure 2 The tooling station 4 includes a bracket 401, a carrying plate 402 installed on the bracket 401, a channel 403 is provided on the carrying plate 402, a cylinder 405 is installed on one end of the bracket 401 through a cylinder seat 406, a push rod 404 is installed on the cylinder 405, and the push rod 404 is placed in the channel 403.

[0042] When the nut moves into the channel 403, the cylinder 405 is turned on, and the cylinder 405 pushes the push rod 404 forward along the channel 403, so that the nut can be pushed to the other end of the bracket 401 and the connection between the branch channel 202 and the channel 403 can be blocked to prevent the next nut from entering the channel 403; when the nut reaches the other end of the bracket 401, the transfer component 5 clamps the nut and moves it to the auxiliary component 3; then the cylinder 405 pushes the next nut to the other end of the bracket 401, so that the transfer operation can be repeated.

[0043] Please focus on Figure 1 The transfer component 5 includes an X-axis single-axis robot 501, a plurality of Y-axis single-axis robots 503 installed on the X-axis single-axis robot 501, and a finger-gripping cylinder 502 installed on the Y-axis single-axis robot 503, wherein the number of the Y-axis single-axis robots 503 is equal to the number of the tooling stations 4.

[0044] After the nut reaches the other end of the bracket 401 , the Y-axis single-axis robot 503 drives the finger clamping cylinder 502 to approach the nut, the finger clamping cylinder 502 clamps the nut, and then the X-axis single-axis robot 501 drives the nut to approach the auxiliary component 3 .

[0045] Please focus on Figure 4 and Figure 5 The auxiliary component 3 includes a base plate 301, a telescopic cylinder 303 mounted on the base plate 301, and a long fixed rod 310 and a short fixed rod 311. The telescopic cylinder 303, the long fixed rod 310 and the short fixed rod 311 are arranged to form a trapezoid. One end of the long fixed rod 310 is hinged on the lower clamping plate 309, and the other end of the lower clamping plate 309 is hinged on the base plate 301. One end of the short fixed rod 311 is hinged on the upper clamping plate 308, and the other end of the upper clamping plate 308 is hinged on the base plate 301. One end of the telescopic cylinder 303 is hinged through a connecting rod 304. It is connected to the connecting rod 307, the other end of the long fixed rod 310 is hinged to the connecting rod 307 through the connecting rod 2 305, and the other end of the short fixed rod 311 is hinged to the connecting rod 307 through the connecting rod 306. At the same time, the connecting rod 307 is hinged to the base plate 301, and the base plate 301 is covered with a cover 302. The cover 302 is provided with a nut inlet 312, and the base plate 301 is provided with an opening corresponding to the nut inlet 312. At the same time, the top inner wall of the cover 302 is provided with a sprinkler head 313 and an air inlet 314, and the bottom inner wall of the cover 302 is provided with a water outlet 315.

[0046] Furthermore, the hinge point at which the connecting rod 307 is hinged on the base plate 301 is located between the hinge point at which the connecting rod 2 305 is hinged on the connecting rod 307 and the hinge point at which the connecting rod 306 is hinged on the connecting rod 307, thereby ensuring that when the long fixed rod 310 moves upward, the short fixed rod 311 descends, and then after the telescopic cylinder 303 is opened, the cooperation between the upper clamping plate 308 and the lower clamping plate 309 can clamp the nut.

[0047] When the nut is fed into the nut inlet 312 by the finger clamping cylinder 502, the other end of the nut is exposed from the opening of the bottom plate 301, and the telescopic cylinder 303 is turned on at the same time. The telescopic cylinder 303 pushes the upper clamping plate 308 and the lower clamping plate 309 to clamp the nut, and the finger clamping cylinder 502 always clamps the nut during the processing, so that the upper clamping plate 308 and the lower clamping plate 309 further fix the nut, thereby preventing the nut from shaking during the processing. When the lathe performs preliminary pre-punching, the bottom plate 301 can block the chips on the other side, thereby preventing the chips from damaging the nut body or affecting the nut. At this time, the nut will have some chips and lubricating oil. In order to avoid affecting the staff's observation of the pre-punching state of the nut, the telescopic cylinder 303 is turned on to loosen the nut. At the same time, the nut is driven by the Y-axis single-axis robot 503 to move into the cover 302, and the spray head 313 is turned on to clean the nut first to wash away impurities on the nut.

[0048] Then, the air inlet is opened, and hot air enters the nuts through the air inlet for drying, and the cleaned sewage flows out through the outlet 315, so that the sewage does not flow onto the workbench or the ground, thereby avoiding polluting the working environment.

[0049] Furthermore, the base plate 301 and the cover 302 are made of acrylic board, so that during the cleaning and drying process, it is convenient for the staff to observe the pre-punching state of the nut.

[0050] After the nuts are dried, if the staff is not satisfied with the pre-punching state, the Y-axis single-axis robot 503 sends the nuts out for reprocessing, and then performs the cleaning and drying operations again, and finally recycles the processed nuts.

[0051] The vibration plate 1, the telescopic cylinder 303, the spray head 313, the air inlet 314, the water outlet 315, the cylinder 405, the finger clamp cylinder 502, the X-axis single-axis robot 501 and the Y-axis single-axis robot 503 are communicatively coupled to the control panel.

[0052] The control panel contains a PLC controller, which can program the numerical control system. The PLC is used as the central control system, and the touch screen is used to realize the program input and operation control of the whole machine, so as to realize the full automation of the transportation process. The control system can be used as a system that connects various actuators to move according to the logical trajectory, and the actuators can be controlled by programming to run according to the required operation steps.

[0053] Based on the above device, the present invention also proposes a rivet nut processing device and an operating method thereof, comprising the following steps:

[0054] Step 1: Feeding nuts by vibrating plate 1;

[0055] Step 2: The nut reaches the tooling station 4 from the nut channel 2;

[0056] Step 3, the transfer component 5 transfers the nut to the auxiliary component 3;

[0057] Step 4: pre-punching the nut;

[0058] Step 5, the transfer assembly 5 returns the nut to the auxiliary assembly 3 for cleaning and drying;

[0059] Step six, reprocessing the nut;

[0060] Step 7, the transfer assembly 5 returns the nut to the auxiliary assembly 3 for cleaning and drying;

[0061] Step 8. Place the processed nuts in a unified manner.

[0062] The device performs pre-punching processing on the nut, and the operation is fully automated. At the same time, it can prevent chips from affecting the nut, and can immediately clean and dry the nut, so that the staff can observe the pre-punching status of the nut and can immediately reprocess it, thereby ensuring the processing quality of the pre-punching.
