10 is an exploded perspective view of the driving unit of FIG. 1. As shown, the drive unit 60 is to rotate the rotary jig 50 while the press rod 42 presses one end of the rivet to form the release preventing cap (150a, 250a), the lower frame 20 A rack unit 62 slidably installed in the rack unit, a rack unit driving hydraulic cylinder 61 for driving the rack unit 62, and a pinion unit coupled to the rack unit 62 and having a rotary jig 50 installed at an edge thereof ( 63). At this time, one end of the rack driving hydraulic cylinder 61 is supported by the pressure sensing unit (70).

The rack 62 is linearly moved on the lower frame 10 by interlocking with the rack driven hydraulic cylinder 61, and the pinion 63 is configured to rotate the rotary jig 50 by changing the linear motion of the rack 62 into a rotary motion. The pivoting drive is driven around the fixed jig 30. In this embodiment, the drive unit is composed of a rack unit and a pinion unit interlocked by the hydraulic cylinder, but this is only one embodiment, of course, can be implemented by various means such as a hydraulic motor or an electric motor.

The pressure sensing unit 70 is applied to the hinge when the rotary jig 50 rotates the first support member 110 and 210 about the rivet while the press unit 40 presses one end of the rivet. The torque is measured to control the operation of the press unit 40 and the drive unit 60. The pressure sensing unit 70 senses the pressure applied to the rack driving hydraulic cylinder 61 by supporting one end of the rack driving hydraulic cylinder 61, and when the pressure is greater than or equal to the set pressure, the pressure sensing unit 70 is used as a controller not shown. The signal is transmitted to prevent the press unit 40 and the drive unit 60 from being driven.

When the press rod 42 presses one end of the rivet to form the release preventing caps 150a and 250a, when the first support member 110 and 210 are rotated according to the pressing strength applied to the rivet, The torque applied to the first support member is different. That is, as the gap between the washer springs constituting the hinge is narrowed, the frictional force by the washer springs increases, which leads to an increase in torque. If the torque is large, it is difficult to rotate the first support members 110 and 210 (which means that the monitor does not rotate well with respect to the stand), and if the torque is small, the first support member rotates too easily (this is the monitor). Means it rotates too easily with respect to the stand). Therefore, it is necessary to generate an appropriate torque when the first support member is rotated with respect to the rivet, which means that the compressive strength of the rivet should not be higher than the set value.

When the rack portion 62 rotates the pinion portion 63 by the rack portion hydraulic cylinder 61, the rotary jig 50 rotates the first support member 110, 210, wherein the press rod 42 is As one end of the rivet is squeezed, the torque applied to the first support members 110 and 210 is gradually increased, which is transmitted to the rotary jig 50 as it is. Since the rotary jig 50 is installed in the pinion portion 63, the torque is transmitted to the rack portion 62 through the pinion portion 63. Then, the driving force for the rack drive hydraulic cylinder 61 to move the rack 62 is increased, and the drive force acts as a force for the rack drive hydraulic cylinder 61 to pressurize the pressure sensing unit 70 in reaction. The pressure sensing unit 70 senses this reaction and sends a signal to the control unit, and the control unit outputs an amount of oil applied to the rack drive inlet cylinder 61 or the press rod driving hydraulic cylinder 41 when the reaction is greater than the set value. To control. In this way, the assembly of the hinge is completed by preventing the press rod 42 from pressing one end of the rivet any more.

According to the hinge assembly device as described above, when assembling the first embodiment of the hinge, as shown in Figure 8, the fixing fitting protrusion 152 of the rivet 150 is directed downward, washer spring 120b After the first support member 110, the washer spring 120a, and the washer 130 are sequentially inserted into the rivet 150, the fixing fitting protrusion 152 is fixed to the groove 142 of the second supporting member 140. ) Assemble the hinge. Then, the preassembled hinge is seated on the seating portion 31, and the press rod 42 causes the rivet to pressurize. Then, at one end and the other end of the hinge, the separation prevention cap formation groove 42a of the press rod 42 and the separation prevention cap formation groove 32a of the seating portion 31 are prevented from separation as shown in FIG. 11. Caps 150a and 152a are formed to complete the assembly of the hinge.

In addition, when assembling the second embodiment of the hinge, as shown in Figure 9, the fixing fitting protrusion 252 of the rivet 250 is directed downward, the stopper 240, washer spring 220b, the first The support member 210, the washer spring 220a, the washer 230 is temporarily assembled to the rivet 250 to be assembled. The preassembled hinge is then seated on the seating portion 36 and the press rod 42 presses the rivet. Then, at one end of the hinge, as shown in Figure 12 by the separation prevention cap forming groove 42a of the press rod 42 is formed as the separation prevention cap 250a is completed assembling the hinge.

Although the present invention has been described with reference to the above embodiments, this is only one embodiment, and those of ordinary skill in the art can implement a variety of other embodiments from this.

As described above, according to the hinge assembling apparatus according to the present invention, by assembling the hinge, a large amount of the hinge can be quickly assembled by adopting a crimped rivet without employing a bolt and a nut.

In addition, the pressure sensing unit senses the torque generated when the first support member rotates to control the compression strength of the rivets, thereby making it possible to make the quality of the assembled hinge constant and to increase the reliability of the product employing the hinge. It works.
