Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

1 is a view showing an arch grinding machine applied to the present invention, the arch grinding machine is a structure for smoothly grinding both sides, the outer surface and the inner surface of the grinding material (1) by continuously conveying the arch-shaped grinding material (1) Is done.

That is, the arch grinding machine, as an example, is a timing at which a guide rail 2 supporting a plurality of grinding materials 1 below guides the grinding material 1 in a longitudinal direction and is connected to a driving gear 3 that is rotated by power. A part of the belt 4 is arranged side by side above the guide rail 2 to move the grinding material 1 positioned on the guide rail 2, and the side grinding to grind the side of the grinding material 1 The grindstone 5 is rotated by power and is installed below the guide rail 2 while being below the timing belt 4, and the outer grinding wheel 6 and the inner surface for grinding the outer surface and the inner surface of the grinding object 1. The grinding wheel 7 is rotated by the power, respectively, and is configured to be separately installed above and below the guide rail 2 while being the exit side of the timing belt 4.

And the front and rear adjustment device of the grinding shaft for the arch grinding machine according to the present invention, as shown in Figure 2 and 3, the grinding shaft rotates together with the grinding wheel (5, 6, 7) for grinding the grinding material (1) (10) is moved back and forth in the axial direction, the fixed shaft (10a) rotatably supporting the grinding shaft 10 is moved in the axial direction (the following axial direction is the same direction as the front and rear direction) to the grinding axis 10 and the grinding wheel 5, 6, 7 are moved in the front-rear direction.

That is, in the present invention, the female screw groove 11 is formed at one side of the slide 8 in the longitudinal direction of the fixed shaft 10a, and the large diameter bearing guide groove 11a is an outer portion of the female screw groove 11. The bearing 13 is formed in the central portion of the adjustment lever 12 having a male screw portion 12a fastened to the female screw groove 11, the bearing is inserted into a part of the circumferential surface of the bearing 13 Insertion groove 14 is formed on one side of the fixed shaft (10a).

Of course, the bearing 13 is movably disposed in the bearing guide groove 11a formed in the slide 8 together with the adjustment lever 12, and the jaw 12b supporting one side of the bearing 13 is provided. A fixed ring 12c, which is integrally formed at the central portion of the adjustment lever 12 and supports the other side of the bearing 13, is installed at the central portion of the adjustment lever 12.

And the present invention includes a sensing means for detecting the front and rear position of the fixed shaft (10a) as shown in Figures 3 and 5, the detection means moves with the fixed shaft (10a) in this embodiment The detection bar 21 is erected upwards, the fixed bar 22 installed on the slide 8 protrudes from the slide 8, and the gauge fixing block 23 is the tip end of the fixed bar 22. Installed in, the dial gauge 24 for indicating the position of the detection bar 21 is made of a structure that is fixed to the gauge fixing block (23).

In addition, the present invention includes a fixing means for fixing the fixed shaft (10a) as shown in Figure 3 and 4, the fixing means are two clamps in close contact with a part of the peripheral surface of the fixed shaft (10a) A hole 31 of the slide 8 is provided with a turnbuckle adjustment lever 33 which is disposed in the hole 32 formed in the slide 8, and the two clamps 31 are spaced apart or close to each other. A large diameter sleeve installed on the outer side of the hole 31 of the slide 8 having a sleeve 34 inserted into and fastened to the two clamps 31 and rotatably supporting the turnbuckle adjustment lever 33. It consists of being installed in the part 31a.

The front and rear adjustment device of the grinding shaft for the arch grinding machine according to the present invention thus formed acts as follows.

The operator adjusts the grinding wheel in the longitudinal direction of the grinding shaft 10 in order for the worker to align the machining center of the grinding object 1 with the grinding wheels 5, 6, 7.

At this time, when the operator rotates the turnbuckle adjustment lever 33 to release the fixed state of the fixed shaft 10a supporting the grinding shaft 10, the two clamps 31 are spaced apart from each other and the fixed shaft 10a. The state of close contact is released, and thus the fixed shaft 10a is movable in the longitudinal direction.

When the adjustment lever 12 is rotated in this state, the male screw portion 12a formed at one side of the adjustment lever 12 is rotated in the female screw groove 11 to move in the longitudinal direction.

As the adjustment lever 12 rotates and moves in the longitudinal direction, the position of the bearing 13 is changed, and at the same time, the fixed shaft 10a moves together with the bearing 13.

Then, the grinding shaft 10 and the grinding wheels 5, 6, and 7 together with the fixed shaft 10a can be moved in the longitudinal direction of the grinding shaft 10 to easily adjust the position of the grinding wheel.

At this time, while the detection bar 21 of the sensing means is moved, the scale of the dial gauge 24 is variable, and the degree of movement can be visually confirmed with precision.

When the movement is completed, the turnbuckle-type adjustment lever 33 is tightened again to the original position so that the two clamps 31 fix the fixed shaft 10a and the grinding shaft 10 due to the fixing of the fixed shaft 10a. ), The grinding shaft 10 and the grinding wheels 5, 6, and 7 are rotated in position in the state where the front and rear positions thereof are variable, so that the grinding material can be easily processed.

As described above, the front and rear adjustment device of the grinding shaft for the arch grinding machine according to the present invention finely adjusts the front and rear positions of the grinding shaft, that is, the longitudinal direction of the grinding shaft, so as to finely adjust the front and rear positions of the grinding wheel, so that the small size change of the grinding object The advantage is that the machining center of the grinding material and grinding wheel can be precisely grasped to produce the grinding material precisely.
