Abstract

PURPOSE:To ensure engagement of screws by pushing a coupling to a pipe at a right angle to a pipe axis at a constant pressure and feeding at a rate of feeding different from the lead of the screw while rotating the coupling. CONSTITUTION:When a coupling B is forwarded to the direction of a pipe A and reached the point E, the rate of feeding is reduced to approx. 75% of the lead of the screw, and the coupling B is pushed to the direction of an arrow P with the force of approx. 100-120kg. This time, a screw thread portion 41 of the screw 40 of the coupling B is contacted to a screw thread portion 51 of the screw 50 of the pipe A. The rate of feeding of the coupling B is approx. 75% of the lead of the screw, then the screw 40 is moved relatively to the direction of an arrow R to the screw 50. Then, the thread 41 of the coupling B is slid to the R direction with 41', 41'' while contacting the thread 51 of the pipe A, and engaging of the thread 40 of the coupling B and the thread 50 of the pipe is completed.

１ねばならず、これが従来装置の大きな欠点であった。Next, the operation will be explained. First, the pipe A has a skid 9 whose stopper position is slid in advance according to its diameter.
1, the cylinder 64 is activated and the upper frame 6.3 is turned into a V-shape! The roller 77 is raised until it comes into contact with the person, and the tip of the tube A is supported by the V-shaped roller 77. Meanwhile, in synchronization with this, the coupling supply mechanism 90 is operated, and the coupling B is automatically supplied to the parallel mill rough 8, so that the coupling B and yA are positioned facing each other. Generally, tube A is often treated with some care during manufacturing or subsequent handling. Therefore, if Coupling B is attached to a person in this state, the mismatch between the center lines of the two parts will likely result in a malfunction in the fit or an accident such as jamming. However, in this device, a type roller 77 and a parallel roller 78 or 70 are installed on a holding table 74, and the floating table 74 is floated by a spring 73 installed on a coupling mounting table 67. Because it is supported, when the person comes into contact with the V-shaped roller 77, the tin ring 73 is activated, and the parallel me rough 8 and this tzV
Coupling B that has been ctt9tt also floats and naturally follows the bending of pipe A, so simply leaving coupling B stationary on the parallel roll 78 will straighten the aluminum of the pipe.
Regardless of I9, the center of the coupling B can be automatically aligned with the taper threaded part. Since the parallel roller 78 has an alignment adjustment mechanism, rotate the threaded shaft 82 in advance to align the center of the coupling B. By moving 81 and adjusting the opening degree of the pair of parallel rollers 78, it is possible to perform the above-mentioned coupling B even if the outer diameter of the tube changes. While being rotated by the hydraulic motor 86, the cylinder 70 approaches the cylinder 70 in the vertical direction and begins to be threaded with the taper threaded portion A', but at this time the vibration motor 75 is activated and rotates. This conventional device applies slight vibrations to the coupling B to prevent it from causing a spray failure at the start of screwing.
When screwing the couplings B and WA onto the same floating table 74, the couplings B and WA are supported by the parallel rollers 77, and the parallel rollers A and Rough B are supported by the rollers 77. 78, the centers of couplings B and gh will be aligned based on the outer diameter of the husband.However, considering the situation of coupling B and the threaded blade of pipe A, the cup The center of the outer diameter of the ring or pipe and the center of the threaded part do not exactly match, and the center of the threaded part of the coupling and the threaded part of the pipe do not exactly match, and the center of the threaded part of the coupling and the threaded part of the pipe are If the lines match, this is almost impossible to expect.If the thread is a triangular thread,
Even if there is a mismatch in the center lines of the threaded part between the coupling and the pipe, it will not cause a major problem in the threading of the coupling and the pipe, but in the case of square threads, the mismatch in the center line of the threaded part Of course, even if there is a mismatch in the center of the threaded part, the threaded part will dry out and it will be difficult to screw together, making it impossible to smoothly screw the ring B into the threaded part of the pipe A to the specified position t. Not only will the scale not work properly, but it may also cause the screws to rust or damage the threads. We have a constant guard stationed for seven reasons.
1, which was a major drawback of conventional devices.

The coupling is pressed against the pipe at a constant pressure in a cross-sectional direction perpendicular to the pipe axis, and the coupling is fed in the direction of the pipe at a feed rate that is different from the lead of the screw while using the coupling ring as a rotation source. The present invention provides a method for ensuring screw engagement.

Since the screw 40 is inserted into the screw 50 of the pipe A and pulled, the current value of the driving electric motor 18 changes. Therefore, if a device is provided to measure the current value of the drive motor 18, it is possible to detect when the engaged state is reached.

When the meshing start point (point F) obtained in advance by a length measuring device (not shown) is reached, a suppressor m (not shown) is activated by a hydraulic cylinder. ) is activated, and the coupling B is pressed against the pipe in the cross-sectional direction perpendicular to the pipe axis.Proceeding further,
When it is confirmed from the change in the current value of the drive DC motor 18 that the screw 40 of the coupling B and the screw 50 of the pipe have reached the engaged state, the compression of the coupling B is released and the feed of the chuck 1 is stopped. Return the lead to the same as the screw lead.

Switch the rotation to low speed and wait for a certain period of time. When the engaged state is detected within a certain time T, the feed of the chuck 1 is returned to its original state as described above, and the coupling B reaches the final position tH, and the screwing device is completed. If no engagement is detected in the T-circle, the rotation of the chuck is stopped and an alarm is issued.
