In addition, welding failure caused by poor handling of the workpieces during the welding operation causes problems such as an increase in the construction time and an increase in the construction cost. In addition, although the quality of the welded part as a whole deteriorates, a specialized welded positioner that meets the requirements for solving such problems has not been developed. Therefore, the welded worker is inconvenient, to be.

FIG. 1 is a perspective view of a welding positioner according to an embodiment of the present invention, FIG. 2 is a perspective view of a rotating plate rotating and a rotating part facing the front, and FIG.

1 to 3, a welding positioner according to an embodiment of the present invention includes a support portion 100, a rotation portion 200, and a lift driving portion 300.

The supports 100 are supported on the bottom surface and are spaced apart and arranged in pairs. The supporting part 100 supports the rotating part 200 and serves to guide the linear movement of the lifting and lowering driving part 300 when the cylinder unit 310 is lifted or lowered.

The supports 100 are supported on the bottom surface and are spaced apart and arranged in pairs. The supporting part 100 is formed as a pair of side plates 110 having a triangular hollow shape on the inner circumferential surface and a triangular outer circumferential surface and at least one side surface of the inner circumferential surface and the outer circumferential surface of the side surface plate 110 And connected to the baffle plate 111 to form a frame shape. Accordingly, the supporting part 100 forms a triangular truss structure by forming the lower frame 120 supported on the bottom surface and the side frame 130 guiding the lifting and lowering of the cylinder unit 310.

The lower frame 120 is supported on the bottom surface, and a plurality of rectangular connection holes 121 are formed in the direction crossing the longitudinal direction. The horizontal beams 122 can connect the coupling holes 121 facing each other to stably fix the supporting portion 100 on the floor surface. Therefore, even if the lower frame 120 is formed as a hollow rectangular cross-section, it can stably support the heavy welding products.

The side frame 130 is an area formed by projecting upward from both ends of the lower frame 110 to form a triangular truss structure. The side frame 130 is formed in a " C "shape in section, and can guide the cylinder unit 310 up and down along a space formed in the" C "

A first connection hole 112 is formed on the upper surface of the side plate 110 and a fourth connection hole 113 is formed on the lower surface of the first connection hole 112. The first connection hole 112 is connected to the second connection hole 213 formed in the protrusion plate 212 of the later described swinging plate 210.

The support portion 100 may include a reinforcing plate 115 connecting the side plate 110 and the transverse beam 122.

The rotary unit 200 is connected to the upper ends of both sides of the pair of supports 100 and rotates to change the working position of the workpiece to various angles (360 degrees). The rotary unit 210, (220) and a jig (230).

The rotary plate 210 includes a pair of protruding plates 212 connected to the upper portion of the support portion 100 arranged to face each other and a support plate 211 connected to the protruding plate 212. The protrusion plates 212 are provided as a pair and include a second connection hole 213 connected to the first connection hole 112 and a third connection And has a hole 214. The third connection hole 214 is connected to the belt plate 320 of the cylinder unit 310 to be described later.

The second connection hole 213 connected to the first connection hole 112 is connected by the first connection pin 215 and the rotation plate 210 is connected to the first connection pin 215 by 90 degrees in both directions So as to incline the welded part coupled to the jig 230 so as to perform the welding operation at various positions. Therefore, since the welder can weld the welding material attached to the C region by rotating the rotary plate 210 after welding the welding material in the region B, the welding time can be shortened and the working efficiency can be increased.

The rotating unit 220 is coupled to the upper side of the support plate 211 and serves to rotate the welding material to change the welding position of the welding material. The rotating unit 220 includes a rotating plate 221, a bearing swing 222, (reducer swing) 223.

Here, as the retainer swing 223 rotates, the bearing swing 221 rotates, whereby the rotary plate 221 rotates to rotate the workpiece. At this time, since the retainer swing 223 is connected to the rotary plate 210, it is possible to maintain the state where the through hole 224 is formed in the center of the rotary plate 210 and the rotary unit 220. When the through hole 224 is formed as described above, the welding position can be welded by rotating the rotary plate 210 in a state in which the welding material located on the back surface of the through hole 224 is not disassembled from the jig. That is, since the conventional axial drive motor can not form a through hole in the rotary plate 221, there is a problem that it must be disassembled in the jig in order to weld the back surface of the weld.

The jig 230 is coupled to the upper surface of the rotary plate 221 at regular intervals along the circumferential direction. The jig 230 may be formed with a T-shaped groove 231 formed in a direction from the center of the circle toward the outer peripheral surface. When the head of the bolt is inserted along the T-shaped groove 231, the head of the bolt is caught by the T-shaped groove 231 and is not separated, and the threaded portion of the bolt protrudes vertically from the T-shaped groove 231. At this time, the vertically projected screw portion and the welded portion are fastened to each other and fastened with a nut or the like, whereby the welding object having various shapes can be firmly fixed.

At this time, the first jig 230a disposed at an interval of 90 degrees from the center of the circle and fixing the large-sized welding object, and the second jig 230b disposed between the first jig 230a and fixing the small- . The first jig 230a can insert a relatively large amount of bolts as compared with the second jig 230b, thereby selectively increasing the welding object according to the size of the welding object, thereby increasing the working efficiency.

Further, the jig 230 may be formed of an electromagnet. When the jig 230 is formed of an electromagnet, when the bolt is inserted into the T-groove 231, the electromagnet state is released, and after the bolt is inserted into the T-groove 231, So that the bolt can be fixed so as not to move, and the welding material contacting the surface of the jig 230 can be more firmly supported so as not to be shaken.

The lifting and lowering driving unit 300 is coupled to the third connecting hole 214 provided at one end of the supporting unit 110 and the other end of the lifting and driving unit 300 is coupled to the lower end of the supporting unit 110, Thereby adjusting the rotation angle of the rotary plate 210. The lifting and lowering drive unit 300 includes a cylinder unit 310, a belt plate 320, and an auxiliary belt plate 330.

One end of the cylinder unit 310 is coupled to the lower portion of the support 110 and the other end of the cylinder unit 310 is provided with a protrusion 311 to connect the belt plate 320. The projections 311 are formed in a cylindrical shape, and the ends thereof are formed so as to be stepped to maintain a firm connection with the strip plate 320. Here, the strip plates 320 are formed as a pair, one end of which is connected to the projection 311 of the cylinder unit 310, and the other end of which is connected to the third connection hole 214.

The auxiliary strip plate 330 is formed of an arc-shaped strip and is connected to the protrusion 311 and the fourth connection hole 113 formed in the side plate 110. The auxiliary strip plate 330 is formed in a concave shape such that the circular arc shape is directed toward the bottom surface in a state where the rotary plate 221 is horizontal so that the auxiliary strip plate 330 rotates in a direction wrapping the connection pin 215 when the rotary part 210 rotates So that it is possible to maintain a firm pivoting state even after the rotation of the rotary part 210.

Further, the cylinder unit 310 may further include a hydraulic pressure fixing device (not shown). When the cylinder unit 310 is inclined at a predetermined angle, the hydraulic pressure fixing apparatus can prevent the inclination angle of the cylinder unit 310 from being changed by the weight of the welding member, Welding quality can be obtained and worker safety accidents can be prevented.

4A and 4B are operation diagrams showing the rotation of the lifting and lowering driving unit according to the embodiment of the present invention.

4, it is to be understood that one of the pair of side plates 110 provided on the supporting part 100 is not shown in order to check the pivoting state of the lifting and lowering driving part 300. [

The lifting and lowering drive unit 300 includes the cylinder unit 310, the belt plate 320, and the auxiliary belt plate 330 as described above.

One end of the band plate 320 is connected to the protrusion 311 of the cylinder unit 310 and the other end is connected to the third connection hole 214. Here, the respective connected points are pin-connected and held in a rotatable state. At this time, the control unit 500 can release the hydraulic pressure of the cylinder unit 310 on the left side and supply the hydraulic pressure to the cylinder unit 310 on the right side. By the linear movement of the cylinder unit 310, the belt plate 320 and the auxiliary strip plate 330 connected to the left cylinder unit 310 are rotated counterclockwise, and the rotary plate 210 is also rotated counterclockwise So that the rotating part is inclined. At this time, the length of the cylinder unit 310 on the right side becomes longer due to the supply of the hydraulic pressure, thereby facilitating smooth rotation of the rotary plate 210 in the counterclockwise direction.

The strip plate 320 and the auxiliary strip plate 330 connected to the ends of the left cylinder unit 310 are folded so as to be wrapped around the space formed inside the side plate 110 and the end of the right cylinder unit 310 And the auxiliary strip plate is rotated in the counterclockwise direction on the upper side.

At this time, the auxiliary strip plate 330 is connected to the protrusion 311 of the cylinder unit 320 and the fourth connection hole 113 formed in the side plate 110 to surround the connection pin 215, Can be maintained firmly. That is, it is possible to maintain the rigid state while supporting the protruding portion 311 and the belt plate 320 of the cylinder unit 320 even when the weight of the welded material is obliquely mounted on the jig 230.

When the hydraulic pressure is released on one side for tilting the rotary plate 210, the pair of cylinder units 310 can increase the working efficiency by tilting the rotary unit 200 in both directions by supplying oil pressure to the other side . Each of the hydraulic cylinders 310 is driven by the control unit 500. When the control unit 500 inputs the rotary plate 210 at a predetermined angle, the rotary unit 210 is rotated at a predetermined angle It is possible to supply or release the hydraulic pressure of the cylinder unit 310 to rotate, or to control the driving unit to rotate the rotation unit 200 at a predetermined angle.

That is, the rotation part 200 and the elevation driving part 300 are controlled by the control part 500 so that the welding position can be adjusted irrespective of the shape of the welding object so that the welding position is horizontal with the bottom surface. As such, if the welding position is horizontal to the bottom surface, the worker can work in a stable state, welding can be prevented from flowing, welding can be performed with a constant thickness, and welding quality can be improved.

FIG. 5 is a conceptual diagram showing an elevation drive of a table according to an embodiment of the present invention. FIG.

As shown in FIG. 5, the present invention may include a table lifting driver 400. The elevation drive unit 400 can automatically perform the welding operation by adjusting the elevation of the worker, thereby stably setting the welding height regardless of the size of the workpiece or the physical condition of the welder. The table lifting and lowering drive unit 400 can be operated by electric or hydraulic pressure, and the operation method thereof is not limited thereto.

It should be noted that the embodiments of the present invention disclosed in the present specification and drawings are only illustrative of the present invention in order to facilitate description of the present invention and to facilitate understanding of the present invention and are not intended to limit the scope of the present invention. It will be apparent to those skilled in the art that other modifications based on the technical idea of the present invention are possible in addition to the embodiments disclosed herein.
