Description

[Technical field]

[0001] The present invention relates to a positioner. [Background technology]

[0002] In general, steel columns, such as column columns, SRC columns, and round pipe columns for steel frame buildings, are manufactured by welding so that the joints and long columns, which have been previously welded, are continuous in the longitudinal direction. When welding steel columns, a rotating positioner is used, and the welding work is performed using a welding device that can hold both ends of the steel column on the rotating positioner and move along the longitudinal direction of the steel column.

[0003] The joints used here are generally made by circumferentially welding diaphragms to both ends of a column with the same cross section as the long pillar material to create a joint core as a core material, and then welding a so-called bracket to the joint core, which is a heavy object with a complex shape. In order to perform welding work on steel columns, a positioner is also required to hold this joint in a position that can be changed to make the welding work easier.

[0011] (First embodiment) The joint positioner to which the present invention is applied will be described below with reference to the drawings. Note that this embodiment is an example of a positioner according to the present invention, and the present invention is not limited to the configuration of this embodiment. Figure 1 is a perspective view showing the positioner of the present invention holding a workpiece. Figure 2 is a side view showing the positioner of the present invention. Figure 3 is a plan view of Figure 2 showing the support table on which the workpiece is placed.

[0012] As shown in FIGS. 1 and 2, the positioner 100 includes a device main body 10, an arm 20, and a support base 30. The device main body 10 includes a device body 10, an arm 20, and a support base 30. The device body 10 has a lifting device 11 that lifts and lowers the arm 20, an arm rotation device 12 that rotates the arm 20, and a control device (not shown). The arm 20 extends horizontally from the device body 10, and is provided with a support table 30 on the tip of which the workpiece 1 is placed. The support table 30 has a workpiece W fixed thereto and is rotated by a rotation drive unit 21 provided on the arm 20. The control device controls the lifting and lowering operation of the arm 20, the rotation operation of the arm 20, and the rotation operation of the support table 30. The lifting and lowering position and the rotation position of the workpiece W fixed to the support table 30 can be adjusted to various positions by the device body 10 and the arm 20 as appropriate.

[0013] The workpiece W is a so-called joint, and has a joint core Wa extending in the vertical direction and a beam attachment part Wb extending in a direction perpendicular to the joint core Wa. The joint core Wa is formed by welding end plates Wa2 to both ends of a rectangular pillar-shaped support part Wa1. The beam attachment part Wb is formed with an I-shaped cross section by a vertical plate Wb1 extending along the extension direction of the support part Wa1 and a pair of flange plates Wb2 welded to both ends of the vertical plate Wb1, and the base end side is welded to each wall surface of the support part Wa1. In this embodiment, the workpiece W is arranged in four directions by attaching the beam mounting portions Wb to each wall surface of the rectangular column-shaped joint core Wa, and forms a cross-shaped workpiece centered on the joint core Wa when viewed in a plane.

[0014] The lifting device 11 has a pair of rails 13 extending in the vertical direction, a lifting body 14 that moves up and down along the rails 13, and a ball screw 19.

[0015] As shown in FIGS. 1 and 2, the arm rotating device 12 has an arm rotation shaft 15 extending horizontally from the lifting body 14, and an arm rotating body 16 that rotates about the arm rotation shaft 15.

[0016] The arm 20 has a rotation drive unit 21 that rotates the support base 30, an arm fixing unit 22 that firmly attaches and fixes the base end side to the arm rotating body 16 on the device main body 10 side, and a pair of arm units 23 extending horizontally from the arm fixing unit 22.

[0017] The rotational drive unit 21 is a plate-shaped member formed in a ring shape along the support base 30, and has a rotational base to which the support base 30 is attached and fixed with the support base 30 placed on it, and a drive unit that rotates the rotational base around the axis of the center of the opening portion. The pair of arms 23 extend in directions away from each other toward the tips so as to avoid an opening formed in the center of the turntable, and support the rotating turntable from below. This configuration can be seen in FIG. 4.

[0018] (Support stand 30) Next, the configuration of the support base 30 will be specifically described with reference to Figs. 3 to 8. Fig. 4 is a perspective view showing the arm and the support base. Fig. 5 is a plan view showing the support base. Fig. 6 is a perspective view showing the fixing clamp to which the workpiece is fixed. Fig. 7 is a front view showing the fixing clamp to which the workpiece is fixed. Fig. 8 is a plan view showing the fixing clamp to which the workpiece is fixed.

[0019] The support base 30 has a longitudinal support frame 31, a support groove 34 formed in the support frame 31 along the longitudinal direction of the support frame 31, a reinforcing member 35 attached to the support frame 31 along the support groove 34, a scale 36 provided along the support groove 34, and a fixing mechanism 40 provided in the support groove 34. The four support frames 31 are arranged in a rectangular shape along the rotation drive unit 21 to configure the support base 30.

[0020] The support grooves 34 extend to both ends of the support frame 31, and two of them are formed side by side in the width direction of the support frame 31. Note that it is sufficient that a plurality of support grooves 34 are arranged side by side in the width direction of the support frame 31, and a configuration in which three or more support grooves 34 are arranged side by side may also be used. Fixing holes 34a penetrating the bottom surface are formed in the bottom surface of the support groove 34. A plurality of fixing holes 34a are arranged at predetermined intervals along the extension direction of the support groove 34. Components constituting the fixing mechanism 40 are fixed with pins in the fixing holes 34a.

[0021] The reinforcing member 35 extends along the support groove 34 and has an L-shaped cross section so as to fit along the surface of the support frame 31 and the depth direction of the support groove 34. The reinforcing member 35 is formed so that the depth direction is shorter than the depth of the support groove 34. The reinforcing member 35 forms a step in the depth direction of the support groove 34, making the opening narrower than the bottom. That is, the support groove 34 is formed into a rail shape by providing the reinforcing member 35. This configuration can be seen in FIG. 6.

[0022] (Fixing mechanism 40) As shown in Figures 3, and 6 to 8, the fixing mechanism 40 has a fixing clamp 41 that fixes the workpiece W, a receiving plate member 42 on which the workpiece W is placed, a regulating member 43 that prevents the fixing clamp 41 from coming loose, and a positioning member 44 that positions the workpiece W. The direction in which the fixed clamp 41 is inserted from the end of the support groove 34 is referred to as the front side in the front-to-back direction, the direction in which the fixed clamp 41 slides toward the closer end of the support groove 34 is referred to as the rear side in the front-to-back direction, and the direction perpendicular to the surface on which the workpiece W is placed is referred to as the up-down direction.

[0023] As shown in Figure 7, the fixing clamp 41 has a sliding portion 41a that is inserted into the support groove 34 from the end of the support frame 31 and slides along the support groove 34, a main body portion 41b that is attached and fixed to the sliding portion 41a and positioned on the upper surface side of the support groove 34 and the reinforcing member 35, and a bolt fixing portion 41c at the front of the main body portion 41b to which a fixing bolt 45 is fastened.

[0024] 7, the bolt fixing portion 41c is formed to protrude forward beyond the front end of the sliding portion 41a, so that the fixing clamp 41 is formed in a crank shape as viewed from the front.

[0025] A pressing body 46 is provided on the lower end side of the fixing bolt 45. The vertical position of the pressing body 46 can be adjusted by adjusting the amount of fastening of the fixing bolt 45 to the bolt fixing portion 41c. This allows the clamping force of the fixing clamp 41 to act perpendicularly on the flange plate Wb2, improving the clamping force of the fixing clamp 41. In addition, by providing the pressing body 46 at the lower end of the fixing bolt 45, the contact area and frictional force between the fixing bolt 45 and the workpiece W are increased. This further improves the clamping force of the fixing clamp 41. In this embodiment, the main body 41b is firmly fixed to the sliding part 41a by a bolt. This allows the main body 41b to be replaced with a bolt fixing part 41c suitable for the type and size of the workpiece W to be fixed by the fixing clamp 41.

[0026] The receiving plate member 42 has a receiving plate sliding portion 42a that is inserted into the support groove 34 and slides along the support groove 34, a fixed pin 42b that is inserted into the receiving plate sliding portion 42a, and a receiving plate portion 42c that is arranged on the upper surface of the support groove 34 and the reinforcing member 35 and on which the workpiece W is directly placed.

[0027] The receiving plate member 42 slides along the support groove 34 by the receiving plate sliding portion 42a being inserted into the support groove 34. The receiving plate member 42 is pressed against the reinforcing member 35 by bolts and fixed at a predetermined position on the support groove 34. The front end of the fixing clamp 41 is disposed adjacent to the receiving plate member 42, so that the fixing bolt 45 is disposed directly above the receiving plate portion 42c.

[0028] The regulating member 43 has a regulating sliding portion 43a that is inserted into the support groove 34 and slides along the support groove 34, a fixing pin 43b that is inserted into the regulating sliding portion 43a, and a regulating portion 43c that is arranged on the support groove 34 and the upper surface of the reinforcing member 35 and against which the fixed clamp 41 abuts.

[0029] Similar to the receiving plate member 42, the restricting member 43 slides along the support groove 34 by the restricting sliding portion 43a being inserted into the support groove 34. Similar to the receiving plate member 42, the restricting member 43 is fixed at a predetermined position on the support groove 34 by inserting a fixing pin 43b into a fixing hole 34a of the support groove 34. The restricting member 43 is disposed adjacent to the rear end of the fixed clamp 41. As a result, even if the fixed clamp 41 slides toward the end of the support groove 34, the edge of the restricting portion 43c comes into contact with the fixed clamp 41, thereby restricting the sliding of the fixed clamp 41. This reliably prevents the fixed clamp 41 from falling out of the support groove 34.

[0030] As shown in FIG. 8, the restricting fixing hole through which the fixing pin 43b is inserted is provided at a position shifted in the front-rear direction and width direction with respect to the center position of the restricting portion 43c formed in a rectangular shape in a plan view. This results in a difference in the distance between each edge of the restricting portion 43c and the restricting and fixing hole through which the fixing pin 43b is inserted. In the example shown in Fig. 8, the distance is as follows: first edge 43cA>second edge 43cB>third edge 43cC>fourth edge 43cD. According to this configuration, the adjustment of the fixing position of the regulating member 43 fixed by a pin in the fixing hole 34a becomes discontinuous, so that the distance between the fixing clamp 41 and the edge of the regulating portion 43c can be made as narrow as possible by appropriately selecting the edge of the regulating portion 43c that is to come into contact with the fixing clamp 41. Therefore, rattling between the fixing clamp 41 and the regulating member 43 is reduced with a low-cost configuration that does not increase the number of parts.

[0031] The positioning member 44 has a sliding portion that is inserted into the support groove 34 and slides along the support groove 34, and a positioning portion 44c that is positioned on the upper surface of the support groove 34 and the reinforcing member 35 to position the workpiece W on the support frame 31.

[0032] Similar to the receiving plate member 42, the positioning member 44 slides along the support groove 34 by inserting the sliding portion into the support groove 34. The positioning member 44, like the receiving plate member 42, is pressed against the reinforcing member 35 by bolts and fixed at a predetermined position on the support groove 34. The position of the workpiece W placed on the support table 30 is determined by the positioning portion 44c of the positioning member 44 fixed to the support groove .

[0033] (How to fix the workpiece) The procedure for fixing the cross-shaped workpiece W having the joint core Wa and the beam mounting portion Wb to the support base 30 will be described with reference to FIG. First, the positioning members 44 are fixed at predetermined positions in the support grooves 34 so that the workpiece W can be positioned at a predetermined position on the support base 30. In this embodiment, as shown in Fig. 3, a total of four positioning members 44 are provided so as to sandwich at least two orthogonal beam mounting portions Wb among the four beam mounting portions Wb extending from the joint core Wa. Next, the receiving plate member 42 is fixed at a predetermined position in the support groove 34, thereby disposing the receiving plate portion 42c at a predetermined position on the support frame 31. Thereafter, the beam attachment portion Wb of the workpiece W is placed on the receiving plate portion 42c. Next, the fixing clamps 41 are provided at predetermined positions in the support grooves 34, and then the fixing bolts 45 of the fixing clamps 41 are fastened, so that the flange plate Wb2 is clamped vertically between the fixing bolts 45 and the receiving plate portions 42c. In this embodiment, as shown in FIG. 3, a total of eight fixing clamps 41 are provided so as to sandwich the four beam mounting portions Wb, respectively. This fixes the workpiece W to the support base 30. Next, the restricting member 43 is fixed to the rear of the fixed clamp 41. With this configuration, the fixed clamp 41 is reliably prevented from falling out of the support groove .

[0034] (Action and Effects) 3 and other figures, the above-mentioned configuration allows the workpiece W, which has four beam attachment parts Wb provided on each side of the joint core Wa, to be easily and firmly fixed to the support base 30. As a result, even when the workpiece W supported by the support base 30 is switched to various positions by the lifting and lowering operation of the device main body 10, the rotation of the arm 20, and the rotation of the support base 30, the workpiece W fixed to the support base 30 remains stable. In addition, the workpiece W fixed to the support base 30 has the underside of the joint core Wa exposed by the opening of the rectangularly arranged support frame 31 and the opening of the annular rotation drive unit 21, improving workability in welding and other operations using the positioner 100.

[0035] 3, by forming two support grooves 34 side by side in the width direction of the support frame 31, the fixing clamps 41 and the positioning members 44 can be arranged side by side in the width direction of the support frame 31. This facilitates the work of installing and fixing the workpiece W on the support base 30. Also, since the number of fixing clamps 41 that clamp the beam mounting portions Wb can be increased, a heavier workpiece W can be stably fixed to the support base 30.

[0036] In addition, by providing the support frame 31 with the receiving plate member 42, the workpiece W supported by the support base 30 is placed on the receiving plate member 42 which is detachable from the support groove 34. Therefore, the workpiece W, which is a heavy object, does not come into direct contact with the support frame 31, and the support base 30 is less likely to be damaged. It is also possible to use a configuration in which the workpiece W is placed directly on the support frame 31 without attaching the receiving plate member 42 to the support frame 31.

[0037] Furthermore, when there is no space to install the regulating member 43 behind the fixed clamp 41 because the beam attachment portion Wb of the workpiece W is placed on the end side of the support frame 31, a configuration may be provided in which a regulating plate 39 is provided so as to connect the ends of adjacent support frames 31 together, instead of the above-mentioned regulating member 43. This configuration may be seen in FIG. 3.

[0038] Second embodiment The second embodiment of the support table 30 and the fixing mechanism 40 will be described with reference to Fig. 9, showing the differences from the above-mentioned examples. Fig. 9 is a diagram showing a support table that supports a T-shaped workpiece. In this embodiment, the workpiece W is provided in three directions by attaching the beam mounting portions Wb to each wall surface of the rectangular column-shaped joint core Wa, forming a T-shaped workpiece W2 centered on the joint core Wa when viewed in a plane.

[0039] In this embodiment, as shown in Figure 9, a total of four positioning members 44 are provided, each sandwiching two of the three beam mounting portions Wb extending from the joint core Wa that are arranged on the same straight line. Of the three beam mounting portions Wb, two beam mounting portions Wb that are arranged on the same straight line are clamped to the support base 30 side by two fixing clamps 41 arranged to sandwich the beam mounting portion Wb. The remaining beam mounting portion Wb is clamped to the support base 30 side by four fixing clamps 41 arranged to sandwich the beam mounting portion Wb. As a result, the T-shaped workpiece W2 is fixed to the support base 30 side using a total of eight fixing clamps 41.

[0040] According to this configuration, by arranging two support grooves 34 side by side in the width direction of the support frame 31, even if the workpiece W has only three beam mounting portions Wb, there is no need to reduce the number of fixing clamps 41 installed, and therefore the fixation of the workpiece W to the support base 30 is stable.

[0041] Third embodiment The third embodiment of the support base 30 and the fixing mechanism 40 will be described with reference to Fig. 10, showing the differences from the above-mentioned examples. Fig. 10 is a diagram showing a support base that supports an L-shaped workpiece. In this embodiment, the workpiece W has beam mounting portions Wb attached to two perpendicular wall surfaces of a rectangular column-shaped joint core Wa, forming an L-shaped workpiece W3 centered on the joint core Wa in a plan view.

[0042] In this embodiment, as shown in FIG. 10, an L-shaped workpiece positioning member 60 for positioning a joint core Wa is attached to the support base 30 in place of the above-mentioned positioning member 44. The positioning member 60 for the L-shaped work extends diagonally across the two support frames 31 on which the two beam mounting portions Wb extending in an L-shape from the joint core Wa are not placed, and has a support plate 61 that fits into the support frames, and a positioning portion 62 that is provided in the middle of the support plate 61 and abuts against the end plate Wa2 of the joint core Wa to position the L-shaped work W3. The two beam attachment parts Wb extending in an L-shape from the joint core Wa are clamped to the support base 30 by four fixing clamps 41 arranged to sandwich the beam attachment parts Wb. As a result, the L-shaped workpiece W3 is fixed to the support base 30 by a total of eight fixing clamps 41.

[0043] According to this configuration, by arranging two support grooves 34 side by side in the width direction of the support frame 31, even if the workpiece W has only two beam mounting portions Wb, there is no need to reduce the number of fixing clamps 41 installed, and therefore the fixation of the workpiece W to the support base 30 is stable.

[0044] (Fourth embodiment) The fourth embodiment of the support table 30 and the fixing mechanism 40 will be described with reference to Fig. 11, showing the differences from the above-mentioned examples. Fig. 11 is a diagram showing a support table that supports an I-shaped workpiece. In this embodiment, the workpiece W is provided in two consecutive directions by attaching the beam mounting portions Wb to each wall surface of the rectangular column-shaped joint core Wa, and forms an I-shaped workpiece W4 centered on the joint core Wa when viewed in a plane.

[0045] In this embodiment, as shown in FIG. 11, an I-work positioning member 70 for positioning a joint core Wa is attached to the support base 30 in place of the above-mentioned positioning member 44. The positioning member 70 for the I-shaped workpiece has a support plate 71 extending to bridge between a pair of support frames 31 on which two beam mounting portions Wb extending in the same straight line from the joint core Wa are not placed, and a positioning portion 72 provided in the middle of the support plate 71 and abutting against the end plate Wa2 of the joint core Wa to position the I-shaped workpiece W4. The two beam attachment parts Wb extending in an I-shape from the joint core Wa are clamped to the support base 30 by four fixing clamps 41 arranged to sandwich the beam attachment parts Wb. As a result, the I-shaped workpiece W4 is fixed to the support base 30 by a total of eight fixing clamps 41.

[0046] According to this configuration, by arranging two support grooves 34 side by side in the width direction of the support frame 31, even if the workpiece W has only two beam mounting portions Wb, there is no need to reduce the number of fixing clamps 41 installed, and therefore the fixation of the workpiece W to the support base 30 is stable.
