Since they are completely the same, the explanation of the structure and operation will be omitted.

Next, to explain how to use it, the horizontally elongated elevating member 71 of the injection means 65 is moved to the lower limit position as shown by the solid line in Fig. 15 by the cylinder/visual unit 85 of the elevating drive means 89 (Fig. For example, when the ground is lowered down to
is transferred to the bolt support plate 75'' of the horizontally elongated lifting member 71. The bolt B to be polished, which is transferred onto the pole 1 support plate 73 and transferred downwardly, comes into contact with the bolt lifting guide rail portion 44C of the bolt support plate 44 of the bolt-receiving stop means 42. In this state, when the horizontally elongated elevating member 71 is raised by the cylinder/bislin unit 85 of the elevating drive means 89 (Fig. 8) to the "1 raising limit position" shown by the solid line in Fig. 3, the bolt support plate 75 Since the pole to be polished IB comes off from the bolt lifting guide rail section 44C, the bolt support plate 73'' rolls downward, and the bolt 1 on the retraction side It moves onto the bolt support plate 44 and stops in a state where it abuts against the protrusion 44b at the lower end of the inclination.

On the other hand, the movable table 51 of the POL 1 transfer means 50 is in a state where the lifting table 54 is lowered to the lower limit by the cylinder/piston unit 55 as shown by the imaginary line in FIG. Move the bolt to the stroke limit on the bolt loading side. At this time, the bolt support base 56 of the lifting table 54 is located at a position corresponding to the pole 1 temporary receiving means 42, and the bolt support base 57 is located at the position corresponding to the pole 1 temporary receiving means 42.
(Fig. 3).

Once the pole to be polished 1-B is supported on each bolt support plate 44 of the bolt stopper means 42 on the loading side as described above, the lifting platform 54 in the pole 1 transfer means 50 is moved. By the cylinder/piston unit 55, the upper part of the support plate 44 is raised up to the upper limit.

The axial center height of B is determined by moving the pair of movable bodies 5a and 5b in each roller unit 2 and 5 toward or away from each other by rotating the screw shaft 8 in forward and reverse directions using the handle 7. It can be arbitrarily adjusted by changing the distance between the bolt supporting rollers 6a and 6b. Also, the first
The fixing position of the bolt positioning stopper 36 shown in the figure is adjusted according to the length of the pole to be polished (I-B), and a freely rotating ball is attached to one end of the pole to be polished (B) supported on the bolt support means 1. 67 is adjacent. Of course, at this time, the height of the elevating member 36 is adjusted by the screw shaft 40 with a handle so that the freely rotatable pole 67 faces the axial center position 7b of the pole to be polished (B).

Next, each air motor unit 9 of the polishing means 9 shown in FIG.
Each polishing rotating brush 13a is operated by operating the polishing brushes 12a to 12C.
15C are rotated in the same direction, the chino 20 of the driving means 11 (FIG. 2) is rotated by the handle 21, and the traverse table 10 is laterally moved to the side where the pole II3 to be polished is located. The three rotary polishing brushes 1-5a to 13C rotated in this manner are brought into sliding contact with the circumferential surface of the threaded shaft portion b1 at one end of the pole IB to be polished supported by the pole 1-supporting means 1, while the bolt shaft By moving in the center direction at an appropriate speed, the pole 1 - one end threaded shaft portion b1 is polished.

Of course, in this case, each polishing rotary brush 13a to 1i5c is adjusted by 1ρ so that each of the polishing rotary brushes 16a to 16C slides into three places on the circumferential surface of the pole l end threaded shaft portion b1 with equal pressure.
Adjust it. Immediately, polishing rotating brush 1 in the upper center
3a is a seat with a fixing handle. By loosening the fixing handle 25, rotate the nut 28 with the pan 1 bolt forward and backward to move the air motor unit 8) 12a up and down, and fix it at an appropriate height. Bread 1

It is sufficient to fasten the fixing handle-equipped NAND 29 and 30 while adjusting the interval 5c.

As described above, the polishing rotary brushes 1i5a to 13C are brought into sliding contact with the circumferential surface of the threaded shaft portion b1 at one end of the pole to be polished with appropriate pressure.
Due to the frictional force between the polishing polishing brushes 13a and 1i5c, the polishing pole B is moved between the poles 1 and both roller units 2.6 of the support means 1 at a circumferential speed that is moderately slower than the peripheral speed of the rotating polishing brushes 13a to 1i5c.
It will rotate on its axis. Therefore, the bolt one end threaded shaft portion b1 has its entire circumferential surface polished by the polishing rotating brushes 15a to 15.
It will be polished with C. At this time, the pole to be polished)B1
0, an axial thrust is applied in the direction of movement of the polishing means 9, and the bolt supporting means 1''2 tends to skid in the axial direction. Side slipping in the axial direction is prevented by the other end surface of the polished pole IB coming into contact with the freely rotatable ball 57 of the bolt positioning stopper i55. Of course, since the freely rotatable ball 67 is adjusted in position so as to come into contact with the axial center position of the other end of the pole IB to be polished, there is no fear of interfering with the rotation of the bolt B to be polished.

In addition, each air motor unit 12a of this polishing means 9
When 12c is in operation, Pol I/Transporter 19
In order to avoid danger, it is desirable to have an interlock in the control circuit so that each of the cylinders and screws 52 and 55 cannot be avoided from operating.
Although the polishing means 9 was configured to be manually moved back and forth,
It can also be configured to mechanically move back and forth using a motor or cylinder/viston UNISO 1.

After polishing the threaded shaft portion b1 at one end of the polished pole B as described above, air motor units 12a to 1
2c is stopped, and the handle 21 is rotated in the reverse direction to temporarily move the polishing means 9 backward to the standby position shown in FIGS. 1 and 2. Then, the elevating table 54 of the bolt transfer means 50 is raised to its upper limit by the cylinder/piston unit 55 again, and the bolt to be polished (B) on the bolt support means 1 is lifted by the bolt support table 56 as shown in FIG. Lift it up. Next, by manually pushing the end of the polished bolt B on the bolt support stand 56 horizontally, the polished bolt B is moved along with the bolt support stand 56 against the vertical axis 60 (the sixth
Rotate horizontally around the image. At the start of this rotation,
The ball 65a of the spring plunger 63 (FIG. 6), which had stopped the rotation of the bolt support base 56, escapes from the recess U64a against the biasing force of the internal biasing spring. In this way, the polishing pole) B is rotated 180 degrees, and the ball 6i5 of the spring plunger 65 is
a is fitted into the recess 641 t υ b provided on the opposite side by the biasing force of the spring, and the bolt support base 56
Lock elastically. As a result, Pol 1 = Polished Pol 1-B on the support stand 56 has the other end threaded shaft portion b2 at the polishing means 9.
It will be in a state where it is facing. In addition, in this way, the bolt support base 5
The bolt B to be polished, which rotates horizontally together with 6, is mounted on the same lifting platform 5.
As shown in FIG. 5, the pole support base 57 is configured to be slightly lower than the bolt support base 56 so as not to contact the pole support base 57 on the bolt support base 56.

Thereafter, the lifting table 54 of the bolt transfer means 50 is lowered to the lowering limit again, the polished pole I-B is transferred onto the bolt support means 1 again, and the polishing means 9 is operated as described above. , the threaded shaft portion b2 at the other end of the bolt B to be polished can be similarly polished. During the polishing work of the threaded shaft portion b2 at the other end of the bolt, the movable base 51 of the bolt transfer means 50 is moved by the cylinder/piston unit 52 to the forward limit position shown by the imaginary line in FIG. The bolt standby on the carry-in side is moved to a position directly below the stop means 42, and the bolt support stand 57 is also moved to a position directly below the pole B during polishing 2.

- Raise the polished pole IB on the bolt support means 1 with the bolt support stand 57 of the bolt transfer means 5o. Next, the movable table 51 of the bolt transfer means 5° is moved backward by the cylinder/piston unit 52 to the backward limit position shown by the solid line in FIG. The Bordeaux standby with B on the unloading side is transported horizontally to just above the stop means 43. After that, by lowering the bolt support base 57 together with the lifting platform 54 to the lowering limit, the polished pin I3 on the bolt support base 57 is removed from each bolt support plate 45 in the stop means 4!1. It will move to the top.

It is also possible to provide a motor for forcibly driving at least one of the polishing rollers B, and to forcibly rotate the polishing pole B by this drive roller.

The bolt polishing device of the present invention can be implemented and used as described above, and its characteristics include providing bolt support means for rotatably supporting the bolt to be polished, and supporting the bolt on the bolt support means. A polishing means for polishing the threaded end portion of the pole to be polished is provided on at least one of the axial directions of the pole to be polished so as to be movable back and forth in the axial direction of the pole to be polished; is caused to rotate by side contact of the rotary polishing tool in the O] grinding means or by driving the Pol I support roller in the Pol I support means, and the loading and unloading sides of the MiJ bolt support means are rotated. A stop means is arranged in parallel on each side of the pole I and the stand-by side, and the pole 1 to be polished on the stop means of the input side pole 1-stand is placed on the support means for the pole 1, and this pole] is supported. This is a bolt polishing device provided with a bolt transfer means for simultaneously transferring the polished pins 1 on the means onto the stop means on the unloading side.
ζ, said POL 1-transfer] A pair of front and rear POL 1 support stands (in the example, bolt support stands 56 and 57) that can be raised and lowered in the stage
), at least one of the poll 1 support stands is configured to be able to rotate within a range of at least 180° around a vertical axis, so that the direction of the polishing poll 1- supported by the poll 1 support means 2 can be reversed. The point is that it is configured like this.

According to such a bolt polishing device of the present invention, a suitable one
As long as the bolt to be polished is fed onto the stop means on the carry-in side by the port means (for example, the bolt carry-in means 65 as shown in the embodiment), the bolt to be polished can be transferred by the bolt transfer means. At the same time as the polished bolt is transferred onto the bolt supporting means, the polished bolt on the bolt supporting means can be carried out onto the stop means at the Bordeaux stand on the carrying-out side,
By operating the polishing means after this transfer, the tip threaded shaft portion of the bolt to be polished on the bolt support means can be automatically polished. Therefore, compared to conventional manual polishing, not only can work efficiency be greatly improved and labor saved, but even non-skilled workers can perform uniform polishing work safely and efficiently. It is possible to do so.

Moreover, the greatest advantage obtained by the device of the present invention is that the polishing means is provided only at one end of the bolt to be polished, but if the polishing of the threaded shaft portion of one end of the bolt to be polished is finished, the M1 bolt can be removed. Reverse the direction of the polished bolt by 80 degrees using the rotatable support of the transfer means,
The advantage is that the threaded shaft portion of the other end of the bolt to be polished can be subsequently polished by the polishing means. Therefore, even if the POL 1- is equipped with threaded shaft portions at both ends, the threaded shaft portions at both ends can be sequentially polished extremely efficiently and safely. Also, compared to the case where polishing means are arranged on both sides of the pole to be polished 1- in the axial direction, or compared to the case where means for reversing the direction of the pole to be polished 1- is provided separately from the means for transferring the pole 1-. According to the present invention, the entire device has a simple structure and can be made small and lightweight. Of course, if the step of reversing the orientation of the bolt to be polished using a pivotable bolt support is omitted, it is possible to use the bolt at one end with a head (11) without any problem.

Although the bolt support stand 57 located on the carry-out side may be configured to be pivotable, it is better to configure the pole 1 support stand 56 on the carry-in side to be pivotable as in the embodiment, considering the work procedure. preferable. Of course, depending on the situation, Pol 1 support stand 56.5
7 may be configured to be rotatable. It is also possible to use a motor or a cylinder/piston unit for rotating the rotatable bolt support base, so that the direction reversal of the bolt to be polished can be performed with zero mechanical force.

1. The work of supplying and unloading the polishing material to the bolt stoppers provided on each of the loading and unloading sides can also be carried out by a hoist, a manipulator, or a forklift using a suitable axo-timen 1. , especially the Pol 1 carrying means 65 and Pol as shown in the embodiment) It
When the ejecting means 66 is provided, not only can it be used conveniently, but also these means 65, 66, the polishing means 9, the bolt transfer means 50, etc. can be fully automatically linked and operated by a microcomputer or sequence circuit. It is also possible to make the polishing work unmanned.
