Description

Technical Field

[0001] The utility model relates to the technical field of arc plate assembly welding, in particular to an arc plate assembly welding tool. Background Art

[0002] In conventional welding assembly operations, a multi-section arc plate assembly welding process is involved. Since the weld between the arc plates is on the arc, when the bevel is butted, the placement of the arc plate is unstable, and multiple workers are required to cooperate to assemble the multi-section arc plates. When welding the arc weld, the hoisting tools need to be lifted and rotated multiple times, and multiple construction workers need to perform multiple leveling and rotation calibrations to ensure accurate positioning. Therefore, in the existing multi-section arc plate assembly welding operations, there are problems such as a large number of arc plate segments, large size, and difficulty in handling or splicing. When it comes to arc thin plates with larger arc diameters, butting the bevel is even more difficult. Utility Model Content

[0003] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a circular arc plate assembly welding tool which is convenient for assembling multiple circular arc plates and improves the efficiency of circular arc plate assembly welding construction.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A circular arc plate assembly welding tool comprises a variable diameter base and a plurality of positioning clamping plates; each positioning clamping plate is provided with a clamping groove for clamping the circular arc plate; the variable diameter base comprises a central fixing seat and a plurality of slide rails symmetrically arranged along the central axis of the central fixing seat; the positioning clamping plate is slidably connected to the slide rails and is locked and fixed by a locking piece; after the circular arc plate is clamped in the clamping groove of the positioning clamping plate, the arc center of the circular arc plate is located on the central axis of the central fixing seat.

[0006] Compared with the prior art, the utility model adopting the above technical solution has the following outstanding features:

[0007] The utility model discloses a circular arc plate is convenient for adjusting the groove angle and position of the circular arc plate, can avoid the weld deviation caused by the circular arc plate being not firmly fixed during welding, reduces the working hours used for lifting, rotating, leveling and calibrating the circular arc plate during the assembly welding, and improves the efficiency of the circular arc plate assembly welding; at the same time, by adjusting the position of the positioning clamping plate on the slide rail, it is suitable for the assembly welding of circular arc plates with different radii.

[0008] As a preferred embodiment, a further technical solution of the utility model is:

[0009] Preferably, a slide groove is provided on the slide rail, the groove opening of the slide groove faces upward, and long holes are symmetrically provided on both side walls of the slide rail, and the long holes are through holes; the lower edge of the positioning card is inserted into the slide groove and can slide along the slide groove, and a positioning hole is provided on the lower edge of the positioning card; the locking part includes a locking bolt and a matching nut, the locking bolt passes through the two long holes and the positioning hole and is locked and fixed by the matching nut; the position adjustment and fixation of the positioning card are simple.

When the positioning card is inserted downward into the slide groove, the horizontal side wings fit against the top surface of the slide rail, thereby avoiding inconsistent depths of each positioning card inserted into the slide groove, resulting in the arc plates not being on the same horizontal plane.

[0019] The present invention is further described below in conjunction with specific embodiments, the purpose of which is only to provide a better understanding of the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.

[0020] like Figures 1 to 5As shown, this embodiment provides a welding tool for an arc plate assembly, including a variable diameter base and a plurality of positioning clamps 3; each positioning clamp 3 is provided with a clamping groove 301 for clamping the arc plate 4; the variable diameter base includes a central fixing seat 1 and a plurality of slide rails 2 symmetrically arranged along the central axis of the central fixing seat 1; the positioning clamp 3 is slidably connected to the slide rail 2 and is locked and fixed by a locking member; after the arc plate 4 is clamped in the clamping groove 301 of the positioning clamp 3, the arc center of the arc plate 4 is located on the central axis of the central fixing seat 1; wherein the central fixing seat 1 is a cylindrical structure, and the slide rails 2 are symmetrically arranged with 4 or 6 pieces about the central axis of the cylinder.

[0021] Preferably, Figure 2 , Figure 3 As shown, a slide groove 201 is provided on the slide rail 2, and the groove of the slide groove 201 faces upward, and long holes 202 are symmetrically provided on the two side walls of the slide rail 2, and the long holes 202 are through holes; the lower edge of the positioning card plate 3 is a plug-in part, which is plugged into the slide groove 201 and can slide along the slide groove 201, and a positioning hole 302 is provided on the lower edge of the positioning card plate 3; the locking part includes a locking bolt 5 and a matching nut, and the locking bolt 5 passes through the two long holes 202 and the positioning hole 302 and is locked and fixed by the matching nut.

[0022] Preferably, Figure 4 , Figure 5 As shown, there may be certain manual errors when manually inserting the lower edge of the positioning card 3 into the slide groove 201, which will cause inconsistent horizontal heights of each positioning card 3, and when fixing the arc plate 4, it will cause inconsistent fixing heights of the arc plate 4; therefore, on the upper side of the insertion portion of the positioning card 3, horizontal side wings 6 are provided on the left and right sides of the positioning card 3. When the positioning card 3 is inserted downward into the slide groove 201, since the width of the horizontal side wings 6 is greater than the slide groove 201, the horizontal side wings 6 are cross-armed on the slide rail 2, thereby ensuring that the depth of each positioning card 3 inserted into the slide groove 201 is consistent.

[0023] Preferably, Figure 5 As shown, a slot 303 adapted to the thickness of the arc plate 4 is provided on the lower horizontal part of the slot 301; after the groove angle and position of the arc plate 4 are adjusted in place, the arc plate 4 is inserted into the slot 303, and the arc plate 4 is shifted when placed for welding.

[0024] Preferably, when fixing the positioning card plate 3, it is necessary to ensure that the positioning card plate 3 is located at the same position of the slide rail 2, so as to ensure that the arc center of the arc plate 4 fixed by each positioning card plate 3 is located at the same point. Therefore, this embodiment provides scale markings on the slide rail 2 along the length of the slide rail 2.

[0025] Before the assembly begins, roughly confirm the placement position of the positioning card plate 3 according to the arc radius of the arc plate 4; place the arc plate 4 in the card slot 301 of the positioning card plate 3, and adjust the groove angle and position of the arc plate 4 according to the welding requirements to adjust to the optimal groove angle. After proofreading, fix the positioning card plate 3 and the slide rail 2, and then start the assembly welding.

[0026] The utility model can avoid the weld deviation caused by the loose fixation of the arc plate 4 during welding, plays the role of assisting the welding of the arc plates 4, reduces the working hours used for lifting, rotating, leveling and calibrating the arc plates 4 during welding, and improves the welding efficiency and welding quality of the arc plates 4.
