In the apparatus for stud bolt and nut work, the main control panel is attached to the right rear side of the main frame. On the main control panel, switches and lamps that operate all tasks are exposed to the outside for smooth operation by the operator. The main control panel is equipped with an electronic switch that detects abnormalities during operation and stops all operations. The main control panel controls all operations with a programmable logic controller (PLC). The main power required for the device is set to 480V three-phase input and 220V three-phase output. The control power supply uses DC24V as an example (not shown). ).

Hereinafter will be described the operating relationship of the apparatus for working stud bolt and nut according to the present invention.

The operator lifts the stud bolt 10 separated from the reactor using a crane, and operates each switch of the main control panel to operate the apparatus for working stud bolts and nuts of the present invention.

First, the rotating frame 120 is rotated 90 ° in a horizontal state, and the stud bolt 10 is mounted on the stud bolt fixing means 200. Thereafter, the upper support 320 and the shock absorber 330 of the clamp means 300 are manually rotated, respectively, so that the idle roller is in contact with the stud bolt 10.

In addition, the worker rotates the rotating frame 120 of the main frame 100 in a horizontal state and lowers the nut conveying means 500 under the nut 20 fastened to the stud bolt 10. Then, the load balancer 520 of the nut conveying means 500 is raised so that the nut seating plate 510 abuts against the nut 20.

Then, the second motor 430 of the stud bolt rotating means 400 is driven to rotate the rotating roller 410 engaged by the chain 420. Then, the stud bolt 10 rotates in frictional contact with the rotary roller 410, the rotational speed of the stud bolt 10 is adjusted by the operation of the second motor 430. In addition, the stud bolt rotating means 400 is automatically stopped by the second motor 430 by the operation of the sensor when overloaded. At this time, the stud bolt 10 is maintained in a horizontal state by each roller support 800, the impact of the rotation is absorbed by the upper and lower supports 310, 320 of the clamp means (300).

The nut 20 is transferred along the guide rail 532 by the nut transfer means 500 while the stud bolt 10 rotates, and is fitted to the locator 610 of the nut separating means 600. The nut separating means 600 rotates the loading frame 620 downward by the operation of the first air cylinder 650, thereby completely separating the nut 20 from the stud bolt 10.

Then, the upper air cylinder 760 of the stud bolt cleaning means 700 is operated to rotate the brush 720 and the upper sealing cover 710 downward, and the lower air cylinder 770 is operated to lower the sealing cover. Causes 712 to rotate upwards. Then, the upper and lower sealing covers 710 and 712 surround the outer circumference of the stud bolt 10, and the brush 720 is in contact with the stud bolt 10. These stud bolt cleaning means 700 is used to install each one on the threaded portion of the stud bolt 10 and the mounting portion of the gauge, but a pair of stud bolt cleaning means 700 is brush 720 is each individually It may be activated or may be operated at the same time. In addition, the stud bolt cleaning means 700 may set the operation time of the brush motor 730 so that the brush 720 is operated for a predetermined time.

Then, the brush motor 730 of the stud bolt cleaning means 700 is operated to clean the thread of the stud bolt 10 with the brush 720. At this time, the stud bolt rotating means 400 rotates the stud bolt 10 in the same direction as the brush 720, thereby making it easier to clean the stud bolt (10).

In addition, the dust collector sucks air into the suction hose connected to the upper sealing cover 710, and removes and removes the foreign matter generated by the operation of the brush 720 to the outside.

After the cleaning of the stud bolt 10 is completed, the brush motor 730 and the second motor 430 are stopped, and the upper and lower air cylinders 760 and 770 are operated to move the upper and lower sealing covers 710 and 712 up and down. Rotate each.

Then, in order to check the shaft diameter of the stud bolt 10, the ring gauge is coupled to the threaded portion of the stud bolt 10 by rotating about 1-2 times. Then, the operator raises the nut seat 510 of the nut conveying means 500 to close the ring gauge. Then, when the stud bolt 10 is rotated in the forward direction, the ring gauge is conveyed along the guide rail 532 by the nut conveying means 500. At this time, the operator measures the axial diameter of each position of the stud bolt 10 by a ring gauge.

After the inspection is completed, the stud bolt 10 is rotated in the reverse direction to separate the ring gauge from the stud bolt 10. The separated ring gauge is stored in a storage box located on the lower side of the main frame 100. After the inspection and cleaning of the stud bolt 10 is finished, a mori coat of lubricant is applied to the threaded portion.

Then, after operating the first air cylinder 650 to rotate the nut separating means 600, the second air cylinder 652 is operated to advance the locator 610 to the end of the stud bolt 10. . Then, the worker transfers the nut 20 mounted on the locator 610 to the stud bolt 10 using the nut transfer means 500. Then, the second motor 430 of the stud bolt rotating means 400 is operated to rotate the stud bolt 10 until the nut 10 is completely fastened to the thread. Then, the worker seals and wraps the threaded portion of the stud bolt 10 to which the nut 20 is fastened with a plastic container.

Then, by rotating the rotary frame 120 in the vertical state by the switch operation of the main control panel, by rotating the upper support 320 of the clamp means 300, the supporting means of the stud bolt 10 is relaxed.

The operator fastens the crane to the stud bolt 10, and separates the stud bolt 10 from the stud bolt and nut working device and stores it in the bolt storage box. In addition, the worker performs the cleaning and inspection work in the stud bolt and nut working device for the other stud bolts as described above.

As described in detail above, the apparatus for working with stud bolts and nuts of the present invention has the advantage that the workability is improved by performing a simple switch operation to clean and inspect the stud bolt, which was difficult to handle by the conventional manual.

In addition, the present invention can obtain a more accurate inspection results by cleaning and inspecting the stud bolts conventionally performed by hand on the ground by automated cleaning means and inspection equipment on the shelf of the main frame, There is an advantage to clean more clean.

In addition, the present invention has the advantage that the operator can work in more harmless working conditions because the suction to remove the foreign matter generated during the cleaning of the stud bolt through the dust collector.

Although the technical idea of the apparatus for working with stud bolts and nuts of the present invention has been described above with the accompanying drawings, this is illustrative of the best embodiments of the present invention and is not intended to limit the present invention. In addition, it is obvious that any person skilled in the art can make various modifications and imitations without departing from the scope of the technical idea of the present invention.
