There is an arm adjusting handle 21 which can move the polishing device to easily adjust the amount in left, right and circumferential directions, and the driven rubber roll 9 is a guide plate 38 which is rotatably coupled by a screw thread 37 ( The bearing 10 is fixed to the inside of the 38-1 so as to be rotatable, and the guide plates 38 and 38-1 are rotated when the sand belt 5 is disassembled so as to be coupled and disassembled. To facilitate.

As shown in Fig. 3, the configuration and operation of the polishing amount microadjustment device of the sand belt 5 are shown in the following manner: the frame fixing latch 40-1 of the ratchet link frame 12 is turned clockwise and the handle 11 is half-washed. When turned in the 켸 direction, the link internal gear bar 7 rotates clockwise to pull the sand belt 5 wound around the driven rubber roll 9, so that the amount of filamentary salt is finely controlled by this rotational force.

As shown in Fig. 4, in order to adjust the length of the sand belt 5, the ratchet link frame 12 is supported by the frame fixing ratchet 40-1 so that the ratchet link frame can be rotated in the circumferential direction. 12 is assembled to the gear-side block 13 by the bush 15, so the ratchet link frame 12 can rotate only in a certain direction, thereby the angle of the ratchet link frame 12 is rotated and the link internal gear bar The length of the sand belt 5 can be arbitrarily adjusted by the rotation angle of (7), and the ratchet 40, 40-1 is composed of a ratchet stopper fixing pin, a ratchet stop ball, and a ratchet stopball spring.

In addition, in order to give the finishing polishing amount to the workpiece 6 to which the sand belt 5 intends to finish grinding, the link internal gear bar 7 which supports the driven rubber roll 9 of the gear side block 13 is compressed and expanded. When the sand belt 5 is subjected to finishing polishing by sand spring 5 being inserted so that one side can be inserted into the other side and the spring 36 is inserted around the outer side so that it can be inserted between the driving rubber roll 16 and the driven rubber roll 9 The finishing polishing amount was determined by the force of the spring 36 to be inserted.

As shown in Figs. 5 and 6, the gear side block 13 and the motor side block 16 each have a pair of tapered rollers to rotate horizontally and circumferentially on various roll and journal bearing assemblies of various diameters ( 50, 50-1, which has a fixed length rack 27 formed on the piston rod 26 of the roll rotating cylinder 25 so that compressed air is provided on the piston rod 26 of the roll rotating cylinder 25. When the inflow is pushed to the spring (36-3) is pressed on the other side to rotate the pinion (28) connected to the rack 27 and at the same time the worm of the rotary bar (30) (30-1) to which the pinion (28) is coupled 29) 29-1 rotates clockwise.

At this time, since the worms 29 and 29-1 of both sides have a left screw worm on the right side and the right screw worm on the left side, the fixing bracket 31 on which the right taper roll 50 of the gear side block 13 is fixed is a worm 29 Rotates in the counterclockwise direction, the left tapered roll 50-1 rotates in the clockwise direction, and at the same time, the motor side block 16 also has the left screw worm in the same way as the gear side block 13, Since the left side is a right screw worm, the taper roll 50 is rotated counterclockwise by the worm 50, and the left taper roll 50-1 is rotated clockwise.

Since it moves up and down by the fixing ball 56 coupled to the end of the close contact bolt 55 to be supported, it can be stably seated on rolls and shafts of various standards and can prevent falling due to the tension of the sand belt 5. have.

As shown in Fig. 7, the roll rotating cylinder 25 is returned by the spring 36-3 inside the piston rod 26, and the idle roll 33 rotates outside the roll rotating cylinder 25. It is possible to act as a pedestal of the brush roll 35 to shake off the foreign matter adsorbed to the sand belt (5), the brush roll 35 is welded to the gear block 13, brush roll 35 It is rotated by the inner bearing to press the sand belt 5 by the weight of the brush roll 35 and at the same time, it is possible to shake off the foreign matter adsorbed on the upper side.

As shown in Fig. 8, the link cylinders 19 are provided on both the blocks 13 and 16 of the driving rubber roll 16 so that the polishing apparatus can have a constant bearing force with respect to the workpiece 6 to be subjected to finishing polishing. To generate a return force, the chain link arm 20 is welded to the link cylinder 19 in the opposite direction of the latch 40-3, 40-4, and the inner side of the arm adjustment handle 21. ), The ratchet (40-3) (40-4) has a ratchet groove having a different ratchet direction on the inner side and can rotate the chain link arms (20, 20-1) to the arm control handle (21). Since the rotation directions are opposite to each other, when the arm adjustment handle 21 rotates, the chain link arms 20, 20-1 rotate in the reverse direction, so that the chain link 23 assembled to the chain link arm rolls with a constant force. (6) is press-fitted.

That is, in order to install the polishing device on the roll 6, the link ball 34 and the guide roll 22 are coupled to the chain link 23 wrapped around the roll 6, and then the link cylinder 19 to a certain distance. After lifting, if the arm adjusting handle 21 is rotated in the clockwise direction, the chain link arms 20 and 20-1 are rotated, whereby the chain link arms 20 and 20-1 are rotated at a constant angle so that the chain link is rotated. The chain link 23 assembled to the arm is pulled out.

On the contrary, when the arm adjustment handle 21 is rotated counterclockwise, the chain link arms 20 and 20-1 are reversely rotated so that they can be applied to various diameters and have appropriate supporting force. And the chain link 23 on which the guide rolls 22 are installed prevent the overlapping part and the returning part from overlapping with each other when the sand belt rotates, and the guide rolls 22 of the link ball 34 Since it is smaller than the diameter, it does not interfere with finishing polishing.

1 to 9, taper rolls 50 and 50-1 are seated in the circumferential direction in accordance with the specifications of the workpiece on both side blocks 13 and 16 to which the driving rubber rolls 16 are fixed. The chain link 34 coupled with the link ball 34 to the chain link arms 20 and 20-1 assembled in the link air cylinder 19 so that the polishing apparatus has a constant bearing force against the workpiece to be polished is attached to the workpiece. Wrap and fasten.

Subsequently, the link cylinder 19 is operated to become a predetermined length and a constant supporting force, and then the arm adjusting handle 21 is repeatedly rotated in a clockwise and counterclockwise manner so as to be adjusted to an appropriate supporting force, and then driven rubber rolls ( 9) The sand belt 5 is wound between the driving rubber roll 16 and the brush roll 35 while the sand belt 5 is wound. Then, the sand belt 5 is hooked and the length of the sand belt 5 is adjusted to match the size of the workpiece. To adjust, the latch 40-1 of the ratchet link frame 19 is placed in the adjusting counterclockwise direction.

In addition, when the arm adjustment handle 21 is rotated while rotating the ratchet link frame 19 counterclockwise, the internal gear 42 formed thereon rotates the link internal gear bar 7 to rotate the driven rubber roll 9. Since the rotation is made at an angle, the tension amount by the spring 36 is generated in the sand belt 5.

As described above, the air motor 17 drives the sand belt drive rubber roll 16 by the spline 18 so as to drive the drive rubber roll 16 after the installation of the sand belt 5 is completed. If you adjust the air control valve that can adjust the rotation speed of the multi ratchet type sand belt finishing grinding device, it is operated. At this time, while holding the handle for horizontal movement and circumferential rotation, it moves repeatedly to the position that you want to finish grinding. Perform a sabotage.

As described above, in the mobile roll polishing apparatus according to the present invention, the surface roughness and foreign matters on the surface having a great influence on the product quality in the leveler roll or the table roll are uniformly polished in the state where the facility is installed to improve the product quality. And the shaft assembly of journal bearings used for large motors, fans, blowers, and spindles is ground in the state where the facility is installed in the field. There is an excellent effect such as minimizing time and maximizing work efficiency.
