[0001] The invention relates to the technical field of hinge processing, in particular to a pin insertion device of a hinge processing machine. Background Art

[0002] Hinge, also known as hinge, is a mechanical bearing used to connect two solids and allow relative rotation between them. It is widely used in doors, windows, furniture and various equipment to achieve flexible opening and closing and fixation between components. Hinge is mainly composed of blades, pins and latches.

[0012] Preferably, a mounting groove is provided on the top surface of the workbench, and a reinforcing plate is fixed inside the mounting groove.

[0013] Compared with the prior art, the pin insertion device of a hinge processing machine adopting the above technical solution has the following beneficial effects:

[0014] 1. The staff will first place the two hinge pieces on one side of the two clamping plates respectively, and use the sliding plate to clamp the hinge pieces between the sliding plate and the clamping plate. At this time, the pin tubes between the two hinge pieces overlap each other, and then the staff will start the second motor. The output shaft of the second motor will drive the rotating plate to rotate. The rotating plate rotates counterclockwise, driving the adding hopper to slide on the top surface of the arc plate, and finally move to the inside of the sliding groove and be above the pin tube between the two hinge pieces. At this time, the bottom of the adding hopper loses the obstruction of the arc plate, so the pin inside the adding hopper will fall. After the pin is added to the top of the pin tube, the rotating plate will rotate clockwise under the drive of the output shaft of the second motor, and then the output shaft of the first motor will drive the rotating plate to rotate clockwise, driving the telescopic rod of the cylinder to move to the inside of the sliding groove and above the pin tube between the two hinge pieces. Then the cylinder starts to work, and the telescopic rod extended by the cylinder will exert a downward force on the pin in the pin tube, so that the pin can be pushed into the pin tube to complete the transmission of the pin. The entire pin insertion process has a very high degree of automation, which increases the efficiency of hinge pin insertion;

[0015] 2. Before fixing the two hinges between the clamping plate and the sliding plate, the staff will first apply pressure to the foot switch, and then the foot switch will send an electrical signal to the PLC controller. After receiving the electrical signal, the PLC controller will send an electrical signal to the electric push rod. After receiving the electrical signal, the telescopic rod extending from the electric push rod will apply a pushing force to the pressure sensor, which can push the sliding plate to slide on the top surface of the workbench, drive the sliding rod to slide inside the sliding hole, and compress the extrusion spring. Then the staff will place the hinge on one side of the clamping plate and remove the pressing force applied to the foot switch. The foot switch will send an electrical signal to the PLC controller again. After receiving the electrical signal, the PLC controller will send an electrical signal to the electric push rod again. The telescopic rod of the electric push rod will be retracted, so the sliding plate will move toward the clamping plate under the push of the compressed extrusion spring. At this time, the pressure sensor loses the pressure applied by the telescopic rod of the electric push rod, so the pressure sensor will send an electrical signal to the PLC controller. Then the PLC controller controls the first motor or the second motor to work and perform the pin penetration work, so that the hinge piece can be fixed between the clamping plate and the sliding plate, thereby increasing the firmness of the hinge piece on the workbench.

[0016] 3. When the staff needs to process hinges of different heights, the staff will first apply a rotating force to the threaded tube. The threaded tube rotates on the surface of the threaded column. The rotating threaded tube will apply the rotating power to the other two threaded tubes through the transmission belt, which can drive the threaded column to move up or down inside the positioning groove, and then increase or decrease the height of the lifting folding plate to adapt to the processing of hinges of different heights, increasing the adaptability of hinge processing;

[0017] 4. When the pin passes through the pin tube between the hinge pieces, the pin tube at the bottom between the hinge pieces is on the top surface of the reinforcing plate. Therefore, when the pin is applied with force by the cylinder to pass through the pin tube, it will impact the top surface of the reinforcing plate. The reinforcing plate made of high-hardness cubic boron nitride increases the impact force that the workbench can withstand, thereby increasing the service life of the workbench.

[0028] During use, the staff will first place the two hinge pieces on one side of the two clamping plates 2 respectively, and use the sliding plate 5 to clamp the hinge pieces between the sliding plate 5 and the clamping plate 2. At this time, the pin tubes between the two hinge pieces overlap each other, and then the staff will start the second motor 10. The output shaft of the second motor 10 will drive the rotating plate 9 to rotate. The rotating plate 9 rotates 180 degrees counterclockwise, driving the adding hopper 11 to slide on the top surface of the arc plate 15, and finally move to the inside of the sliding groove 12, and be above the pin tube between the two hinge pieces. At this time, the bottom of the adding hopper 11 loses the obstruction of the arc plate 15, so the inside of the adding hopper 11 is The pin at the bottom will fall into the top of the pin tube. After the pin is added, the rotating plate 9 will rotate 180 degrees clockwise driven by the output shaft of the second motor 10, and then the output shaft of the first motor 7 will drive the rotating plate 6 to rotate 180 degrees clockwise, driving the telescopic rod of the cylinder 8 to move to the inside of the sliding groove 12 and be above the pin tube between the two hinge pieces. Then the cylinder 8 starts to work, and the telescopic rod extended by the cylinder 8 will apply a downward force to the pin in the pin tube, thereby pushing the pin into the pin tube to complete the transmission of the pin. The entire pin threading process has a very high degree of automation, which increases the efficiency of hinge pin threading.

[0029] like Figure 2 , Figure 4 and Figure 7As shown, a sliding rod 16 is fixed to one side of the sliding plate 5, and two sliding holes 17 are provided on one side of the fixed plate 3. The sliding rod 16 and the sliding hole 17 are slidably inserted.

Two limit grooves 19 are provided on the top surface of the workbench 1, and a limit plate 20 is fixed to the bottom surface of the sliding plate 5.

Two electric push rods 23 are fixed to the top surface of the workbench 1, and a foot switch 24 is fixed to the bottom surface of the workbench 1.

[0030] During use, before fixing the two hinges between the clamping plate 2 and the sliding plate 5, the staff will first apply pressure to the foot switch 24, and then the foot switch 24 will send an electrical signal to the PLC controller. After receiving the electrical signal, the PLC controller will send an electrical signal to the electric push rod 23. After receiving the electrical signal, the telescopic rod extending from the electric push rod 23 will apply a pushing force to the pressure sensor 22, thereby pushing the sliding plate 5 to slide on the top surface of the workbench 1, and driving the sliding rod 16 to slide inside the sliding hole 17, and compressing the extrusion spring 18. Then the staff will place the hinge on one side of the clamping plate 2 and remove the pressure applied to the foot switch 24. The foot switch 24 will send an electric signal to the PLC controller again. After receiving the electric signal, the PLC controller will send an electric signal to the electric push rod 23 again. The telescopic rod of the electric push rod 23 will be retracted. Therefore, the sliding plate 5 will move toward the direction of the clamping plate 2 under the push of the compressed extrusion spring 18. At this time, the pressure sensor 22 loses the pressure applied by the telescopic rod of the electric push rod 23. Therefore, the pressure sensor 22 will send an electric signal to the PLC controller. Then the PLC controller controls the first motor 7 or the second motor 10 to work and perform the pin threading work, so as to fix the hinge between the clamping plate 2 and the sliding plate 5, thereby increasing the firmness of the hinge on the workbench 1.

[0031] like Figure 2 , Figure 4 and Figure 6As shown, the top surface of the fixed plate 3 is provided with a plurality of positioning grooves 25, the bottom surface of the lifting folding plate 4 is fixed with a plurality of threaded columns 26, the positioning grooves 25 and the threaded columns 26 are slidably inserted, the top surface of the fixed plate 3 is fixed with a fixing ring 27, the inside of the fixing ring 27 is rotatably provided with a threaded tube 28, the inside of the fixing ring 27 is fixed with a bearing, the threaded tube 28 is fixed to the inner wall surface of the inner ring of the bearing, the threaded tube 28 is threadedly connected with the threaded column 26, a transmission belt 31 is provided above the fixed plate 3, and the threaded tube 28 is threadedly connected with the threaded column 26.

[0032] During use, when the staff needs to process hinges of different heights, the staff will first apply a rotational force to the threaded tube 28, and the threaded tube 28 will rotate on the surface of the threaded column 26. The rotating threaded tube 28 will apply the rotational power to the other two threaded tubes 28 through the transmission belt 31, which can drive the threaded column 26 to move upward or downward inside the positioning groove 25, and then increase or decrease the height of the lifting folding plate 4 to adapt to the processing of hinges of different heights, thereby increasing the adaptability of hinge processing.

[0033] like Figure 2 As shown, a mounting groove 36 is formed on the top surface of the workbench 1 , and a reinforcing plate 37 is fixed inside the mounting groove 36 .

[0034] During use, when the pin passes through the pin tube between the hinge pieces, the pin tube at the bottom between the hinge pieces is on the top surface of the reinforcing plate 37. Therefore, when the pin is applied with force by the cylinder 8 to pass through the pin tube, it will impact the top surface of the reinforcing plate 37. The reinforcing plate 37 made of high-hardness cubic boron nitride increases the impact force that the workbench 1 can withstand, thereby increasing the service life of the workbench 1.
