【Example】

 The table roller bearing seat processing apparatus of the present invention will be described below with reference to the illustrated embodiment.

In the transport roller table 31 (see FIGS. 3 and 4) in which a plurality of rollers 30 are arranged, the bearing seat 32 of each roller 30 provided on the drive-side and driven-side frames 1a and 1b. The processing device 33 (see FIGS. 1 and 2) for repairing the wrench is capable of expanding and contracting in the longitudinal direction, and also has a supporting base 35 having mounting portions 34, 34 at both ends in the longitudinal direction, and the supporting base 35. Both end portions in the longitudinal direction are provided with both processing portions 36, 36 movably provided in the longitudinal direction.

Then, the two mounting portions 34, 34 adjust the position in the height direction, the perpendicularity to the roller table transport direction, and the roller axis center direction, and support the roller table 31 between the frames 1a, 1b. By mounting and mounting the gantry 35, the bearing seats 32 of both frames 1a and 1b can be repaired by the machining parts 36 and 36 with the same center on the drive side and the driven side after the welding overlay. It is configured to be implemented.

The support base 35 in this embodiment includes an arm case 3 and both arms 9 and 9 arranged on both sides of the arm case 3. Further, the mounting portion 34 includes a saddle receiving frame 16 having the centering bolt 23 built therein, a support base fixing jig 2b, a fixing bolt 2 and a fixing nut 2a.

Further, the processing section 36 includes a main motor 15 attached to a saddle 17 movably provided in a longitudinal direction of a support frame 35, a propeller 11 rotated by the main motor 15, and And a bite 10 attached to a propeller 11.

The repairing work of the bearing seat 32 in the frame 1 of the transport roller table 31 using the working device 33 having such a structure will be described. The roller 30 that has been installed is mounted on the bearing seat 32, and the bearing seat 32 is built up to improve wear resistance and corrosion resistance.

Next, the length L of the support frame 35 in the processing device 33 is adjusted to the length L between the drive-side frame 1 a and the driven-side frame 1 b of the transport roller table 31, which is the frame 1.

In this length adjusting work, the worm 4 is rotated by rotating the expansion / contraction motor 8 provided in the arm case 3, and the wheel shaft 6 (right screw, left screw) screwed to the arm 9 is rotated. The rotation is performed by expanding and contracting the left and right arms 9 by rotating the wheel 5 having the brackets. In FIG. 1, reference numeral 4a is a worm shaft and 4b is a worm bearing.

Next, after setting the length of the processing device 33, the processing device 33 is hoisted by a crane and installed on the frame 1 of the transport roller table 31, and centering for repair processing is performed on both the frames 1a and 1b.

The centering in the height direction in the centering operation at this time is performed by adjusting the centering bolt 23 so that the center of the propeller 11 comes to the center of the side shaft 24. Confirmation is done at the Y level.

Further, the perpendicularity between the line direction of the transport roller table 31 and the processing device 33 is determined by making the side shaft 24 and the processing device 33 at right angles. For confirmation, attach a dial gauge (not shown) to the propeller 11, swing it around the side of the side shaft, and press the pushing jig 25 until the numbers become the same. The pushing jig 25 is attached by welding if necessary.

Further, the position adjustment in the roller shaft center direction is performed by aligning with the roller shaft center. In addition, check with the dial gauge in advance at the marking position and the unworn portion of the bearing engagement surface.

Then, the processing apparatus 33 is fixed by welding the nut 2a onto the frame 1 and tightening the support base 35 with the fixing bolt 2 and the support base fixing jig 2b.

Next, the cutting by the cutting tool 10 for repairing will be described. The propeller 11 with the cutting tool 10 attached is fixed to the main shaft 13 supported by the bearing case 12 containing the bearing, and The main shaft 13 is connected to the main motor 15 via bevel gears 14 and 14 '.

Since the cutting tool 10 here is a single-edged tool, the cutting tool is replaced depending on the cutting direction to change the rotation direction of the propeller. In addition, the feed mechanism of the cutting tool 10 operates the saddle 17 on which the complete rotating mechanism is mounted on the sliding surface of the saddle receiving frame 16, so that the feed motor 18 and the bearing 19 are provided on the saddle side. Also, attach the bearing 20 to the arm side and reciprocate with the feed screw 21.

The feed mechanism of the cutting tool 10 is symmetrical, and the propeller shaft center is also set on the same axis, so that the drive side frame 1a and the driven side frame 1b can be machined with the same core.

Since the motor control of each mechanism is controlled by the inverter, it is possible to change the speed without permission. The processing diameter is measured with a micrometer from the propeller center shaft 26 to the processing surface.

Then, the bolt 2 is removed, the processing device 33 is hoisted by a crane, the nut 2a and the pushing jig 25 are removed, and the grinder is used for maintenance, so that the frame 1 of the transport roller table 31 is removed. The repairing work of the bearing seat 32 is completed.

In the processing apparatus of the present invention, two or more processing apparatuses can be spliced in parallel to increase the working efficiency, such as simultaneous processing at four locations and simultaneous processing at six locations.
