Description

[Detailed description of the invention] TECHNICAL FIELD The present invention relates to a plow barrel assembly device.

Conventionally, when assembling a plow cylinder, the plow teeth were temporarily secured to the plow body with nuts, and then the worker tightened each nut further to secure the plow teeth.

direction, and the tip 34a of the pin 34 is pulled out from the positioning hole 31. Next, the teeth 3 are lightly fastened with nuts 4, but the small-diameter plow body 1, which does not have side plates 5 at either end, is placed on the circular arc portion 16c of the small-diameter plow main body support 16. Next, the piston rod of the first hydraulic cylinder device 18 is reduced. Then, the movable support frame 12 is moved in the direction of arrow A, and the plow barrel fitting portion 14a of the moving side fitting body 14 is moved.
is fitted into one end of the small-diameter plowing trunk body 1, and the small-diameter plowing trunk main body 1 is pushed in the direction of arrow A by the flange 14b, so that the other end of the main body 1 is fitted into the plowing trunk of the fixed fitting body 20. It will fit into the joint portion 25a. As a result, the small diameter plow body main body 1 has a circular arc portion 1
It is in a state where it is slightly lifted from 6c and supported by both fitting bodies 14 and 20. Next, the small diameter plow body 1 is rotated to align the through hole 1a of the main body 1 with the positioning hole 31, and then the operation of the air cylinder 37 is stopped. Then, the positioning lock pin 34 is moved by the arrow C by the spring 35.

Then, each sliding plate 62 is slid in the direction of arrow I via each arm 65 and each link 66, and the sixth
As shown by the imaginary line in the figure, the moving shaft 60 is also moved in the same direction, and the tool 69 is fitted into a predetermined nut 4. The impact during this fitting is absorbed by the spring 73, so that the tool 69 and the nut 4 are not damaged. Next, the pneumatic motor 74 is activated. Then, the rotating rod 67 is rotated in a predetermined direction, and the operating rod 6

Rotate the stationary side fitting body 20 by a predetermined angle via
As a result, the small diameter plow body 1 is rotated by a predetermined angle in the same direction via the positioning pin 34, and the tool 69
The next nut 4 to be tightened is placed opposite the nut 4. At this time, the tool 69 and its nut 4 are aligned with arrow A,
If the position is shifted in the B direction, the second
The drive motor 76 is operated to move the insert 48 in the direction of arrow A.
Alternatively, the tool 69 may be moved appropriately in the B direction to face the next nut 4 to be tightened. Next, the tool 69 may be fitted into the nut 4 by performing the same operation as described above, and the tool 69 may be further tightened. Similarly, each nut 4 may be tightened in turn.

Next, when assembling the large-diameter plow body 2, as in the case described above, the large-diameter plow body 2 is attached to the circular arc portion 17.

4, 15, 20, 21, pull out the tip 34a of the lock pin 34 from the holes 1a, 31, and remove the plow body bodies 1, 2 on the respective arcuate portions 16c, 17c.

As described above, according to the plow barrel assembly apparatus of the present invention, by making the fitting bodies of each pair of a plurality of pairs of supports installed in parallel have a diameter that matches the diameter of the plow barrel main body having different diameters, The insert body, which is compatible with the saw body and is supported by the fitting body, is moved along the front surface of the support body in the direction in which they are juxtaposed, and is moved up and down, thereby allowing the insertion body to be inserted into the saw body with different diameters. Assembling can be quickly performed for a plurality of plow trunk bodies. Furthermore, since one support body is moved closer to and further away from the other and both ends of the wood-throwing body are fitted into the fitting body, the supporting body can quickly and reliably support the wood-throwing body, providing stable support. By rotating the fitted body with a rotary drive device, the positioning of the toothed fixing nut in the body of the plow cylinder relative to the nut tightening tool can be performed smoothly and easily, and the moving axis can be moved in the longitudinal direction of the insert body. By simply moving the nut tightening tool back and forth in the orthogonal direction, the nut tightening tool can be easily engaged with the toothed fixing nut, and each toothed fixing nut can be tightened one after another with a constant pressure, reducing overall assembly time. It has the advantage of being able to
