The present invention relates to a work turn over table used for repairing or replacing a mold, or for reversing work of a machine tool.

More specifically, both rotating plates are mounted on both sides of the bottom of the rotating plate which is independently rotatable on the base of the reversing machine by installing locking means that can adjust the angle. In addition to being deformed at an arbitrary angle, the synchronous rotation of the rotating plate is always maintained at a constant angle.

Conventionally, many hydraulically-operated inverters have been introduced and used for repairing or replacing molds, and for reversing work of other machine tools. However, these inversions facilitate the repair of molds and adjust the angle of the rotating plate. Since the structure uses a stopper, there is a large closed end that cannot be adjusted while giving an angle change arbitrarily, except for the angle set in advance at the time of manufacture. The drawback that deviation occurs and the deviation correction which is very difficult by this are a drawback, and there exists a problem that it causes big trouble in a metal mold | die (inversion) operation.

The present invention solves the above-mentioned shortcomings of the conventional inverters, and it is possible to adjust both rotating plates of the independent type of the inverter at any desired angle and to maintain the angle of the rotating plate to rotate the synchronous. It is an object of the present invention to maintain a constant angle at all times without the occurrence of an angle deviation even during time.

The present invention is a means for achieving the above object, in the inverter configured to be independently rotatable by the hydraulic cylinder is held in the state in which the end portion of the two rotating plate is pinched on the base, On each side of the bottom of the rotating plate, one side end of the fixed rod body in which the spiral part is formed is rotatable, and the other end of the fixed rod body is inserted into the fitting hole of the sliding body installed between the fixing brackets, and the spiral portion Is a combination of adjustment nuts.

The above objects and other advantages will become more apparent from the accompanying drawings and examples. The following examples are merely examples of the present invention and the present invention is not limited thereto.

As shown in Figs. 1 to 5, the support bases 6, 6 ', 6'',6''', 6 '''' are placed at the center of the upper surface of the base. ) Is vertically placed, and one side portion of the rotary shaft 8 laterally built on the bearing base 6, 6 ', 6 ",6'" The rotary plate 4, 5 having the inclined end portions 4 'and 5' that are bent in a magnetic shape is rotatably rotatably held in the state where the inclined end portion 4 'and the end portion 5' are sandwiched.

The bearings 6, 6 ', 6' 'and 6 are provided on the fixed shafts 13 and 13' which are respectively arranged on the inclined ends 4 'and 5' of the rotating plate 4 and 5, respectively. The piston rods 12 and 12 'of the hydraulic cylinders 10 and 10', in which the body part is rotatably mounted, are fixedly rotatably connected in the " "

The rotating plates 4 and 5 are rotated separately from each other about the rotating shaft 8 by the appearance of the hydraulic cylinders 10 and 10 '.

A pair of fixing brackets 14, 14 ′, 16, 16 ′ with a predetermined gap are installed at each of both bottom ends of the rotating plates 4, 5, and the fixing brackets 14, 14 are installed. One end of the fixed rod bodies 22 and 22 ', in which the spiral portions 20 and 20' are formed at the other end, is pivotally relieved in the hinge shafts 18 and 18 'built up in the "). The other side of the fixing rods 22 and 22 'is a sliding hole 29 of the sliding bodies 24 and 24' installed in the fixing brackets 16 and 16 'mounted on both sides of the bottom of the rotary plate 5, respectively. Adjustment nut is provided in the spiral portion 20, 20 'inserted loosely in the 29' and the other end of the fixing rods 22, 22 '. 30, 30 'are combined.

In the above embodiment, the hydraulic cylinders 10 and 10 'for rotation of the rotary plates 4 and 5 are installed in two places, but the hydraulic cylinders 10 and 10' are respectively referred to as the rotary plates 4 and 5, respectively. Depending on the size, it is possible to install two or more, and also the fixing means consisting of a fixed rod body 22, 22 ', sliding body 24 (24') and adjustment nut 30, 30 ' (3 ') also illustrated that two installations on both sides of the bottom of the two rotating plate (4) (5), depending on the size of the rotating plate (4) (5) may be any two or more.

In the drawing, reference numeral 26 denotes a mold, 28, 28 'denotes a hydraulic supply hose, and 32, 32' denotes a hydraulic discharge hose.

With such a configuration, a mold (or a work piece) to be repaired in one upper surface portion of the rotating plate 4, 5 of the present invention inverter 1 which is normally in the state shown in FIGS. 1 and 2 ( After mounting the twenty-sixths, the hydraulic supply hoses 28 of the hydraulic cylinders 10 and 10 'are operated by a valve (not shown) operation to adjust the rotary plates 4 and 5 to a desired angle θ. The hydraulic pressure may be gradually supplied to the 28) side. For example, when adjusting the rotating plate 5 in a state as shown in FIG. 3 (a), when the hydraulic cylinder 10 is operated, a fixed shaft (below the inclined end 5 'of the rotating plate 5) The piston rod 12, which is relieved to be rotatable in 13, presses the inclined end 5 ′ of the rotating plate 5 upwardly as shown in FIG. 3 (a), so that the rotating plate 5 is rotated. It is rotated upward from the horizontal state around. At this time, the fixing rods 22 and 22 'having one end mounted on the fixing brackets 14 and 14' at the bottom of the rotating plate 4 have the other end fixed brackets 16 and 16 of the rotating plate 5. It is caught by the sliding holes 29 and 29 'of the sliding bodies 24 and 24' installed in the '), and the pivot plate 5 rises and the hinge shafts 18 and 18' are centered. Brackets 16, 16 'integrally mounted with the sliding bodies 24, 24' which are rotated in the direction of arrow a (FIG. 3a) and are inserted into the fixed rods 22, 22 '. Sliding in the direction of the arrow (a ') along the fixing rods (22) and (22') is moved from the "P" position of the first Figure 2 to the "P" position of Figure 3 (a), the bracket One side of (16) and 16 'is blocked by the adjusting nut 25 screwed into the spiral portions 20 and 20' of the fixed rod bodies 22 and 22 '. In this way, when the rotary plate 5 is positioned at a desired angle θ, the valve (not shown) may be turned off, and the hydraulic pressure may be stopped if the hydraulic plate 10 is supplied to the hydraulic supply hose 28 side of the hydraulic cylinder 10 until then. In addition, when changing to a larger angle in the state of FIG. 3 (a) (the angle is 90 °), the hydraulic cylinder 10, which has been advanced, is operated to discharge the hydraulic pressure to the discharge hose 32 shaft. The rotating plate 5 acts downward due to the contraction of the rod 12. In this case, the fixed rods 22 and 22 'are centered on the hinge shafts 18 and 18'. And the bracket 16 (1 6 ') integrated with the sliding bodies 24 and 24' is slid along the fixing rods 22 and 22 'in the direction of the arrow b' and the third Each two-dot dashed line position Q (Q ') of FIG. In this way, the hydraulic discharge of the hydraulic cylinder 10 is stopped when the desired angle is reached, and the brackets 16 and 16 'are adjusted by adjusting the adjusting nuts 30 and 30' which are screwed into the spiral portions 20 and 20 '. ) To the moving position Q '.

In addition, when both the rotating plates 4 and 5 in the state of FIG. 3 (a) are rotated for example from the state of FIG. 3 (a) to the state of FIG. 3 (b), When the hydraulic cylinder 10 is contracted and the hydraulic cylinder 10 'is moved forward, the two rotating plates 4 and 5 are fixed by the fixing means 3 and 3'. When the synchronous rotation is performed in the same state as in (b) and in the same state as in FIG. 3 (a) in FIG.

In addition, when returning to the original state of FIG. 1, 2 from the state of FIG. 3 (b), only hydraulic discharge is required.

The hydraulic cylinders 10 and 10 'for pressing the rotating plates 4 and 5 have a center of gravity toward the inner center of the rotating plates 4 and 5 as the piston rods 12 and 12' are advanced. As it is biased, the cylinders 10 and 10 'are rotated upwards as the rods 12 and 12' move forward, as shown in FIG. 3 (a) (b).

As such, the present invention performs the fixing of both the rotating plate (4) and (5) by the sliding body, the fixed rod body, and the adjusting nut, so that the angle can be freely adjusted, unlike the conventional fixed angle by the stopper. In the case of synchronous rotation, in particular, the conventional angle depends only on the pressure of the hydraulic cylinder that rotates both rotating plates, so the weakening of durability due to the extrusion force of the plate and the plate does not preserve the original angle and causes the angle deviation. Unlike the fear that the mold placed on the rotating plate slips, the two rotating plates are fixed by the fixing means, and then rotated synchronously in the left and right directions so that the original angle is always kept constant. There is a feature that there is no fear of slipping on the plate.
