For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] As attached Figure 1-5 As shown, the single-arm assembly welding anti-deformation tool provided by the utility model comprises a support platform 1, a clamping mechanism for limiting the vertical direction of the workpiece 11 to be processed, the clamping mechanism comprises a movable clamping mechanism arranged at one end of the support platform 1 and a fixed clamping mechanism arranged at the upper part of the other end of the support platform 1; a cushion block 5 is also arranged on the upper part of the support platform 1;

[0022] The movable clamping mechanism includes a clamping crossarm 6, a column 8, and a base 10. The lower part of the column 8 is fixedly connected to the support platform 1, and the upper part of the column 8 is hinged to the support body of the crossarm. The end of the crossarm away from the support platform 1 is hinged with a cylinder 9 for driving the crossarm to swing up and down, and the lower part of the cylinder 9 is hinged with the base 10; the lower part of the other end of the crossarm is hinged with a movable pressure plate 7.

[0023] The fixed clamping mechanism includes a positioning block 2 and a fixed pressure plate 3. The positioning block 2 includes a horizontal portion connected to the support platform 1 by bolts and a vertical plate fixedly connected to the horizontal portion. The fixed pressure plate 3 is connected to the side of the vertical plate toward the movable clamping mechanism by bolts.

[0024] The upper part of the support platform 1 is provided with a slide groove 12 which is parallel to the long side of the support platform 1, and the pad 5 is slidably matched with the slide groove 12; the pad 5 is penetrated by a countersunk bolt which passes through the pad 5; the fixation and sliding of the pad 5 can be controlled by tightening and loosening the countersunk bolt.

[0025] A limiting mechanism 4 is also fixedly arranged on the upper part of the support platform 1, and the limiting mechanism 4 includes a fixed limiting block 41, a limiting adjustment block 42, and a connecting plate 43, and the thickness of the connecting plate 43 is less than the thickness of the cushion block 5; the connecting plate 43 is connected to the upper part of the support platform 1 and is perpendicular to the long side of the support platform 1, and both ends of the connecting plate 43 extend outward beyond the edge of the support platform 1, and one end of the upper part of the extending part of the connecting plate 43 beyond the edge of the support platform 1 is fixedly connected to the fixed limiting block 41, and the other end is fixedly connected to the limiting adjustment block 42, and the limiting adjustment block 42 includes a protruding portion and a screw rod which is threadedly matched with the upper part of the protruding portion.

[0026] Specifically, the single-arm welding anti-deformation tool provided by the utility model is mainly used to overcome the stress deformation caused by uneven heating during welding. The main change is that the two sides of the component welding point will bend upward. In order to overcome this bending, the upper part of the support platform 1 in this solution is kept horizontal, and the component 11 to be processed is placed on the pad 5. When the movable clamping mechanism does not apply external force, the component 11 to be processed is in a horizontal state, and the lower surface of the fixed pressure plate 3 contacts the upper surface of the component 11 to be processed but does not squeeze each other.

[0027] In order to facilitate the clamping and disassembly of the workpiece and to be able to apply sufficient force to the workpiece to be processed during the welding process, the present scheme adopts the oil cylinder 9 as the power of the movable clamping mechanism. The execution part of the movable clamping mechanism adopts a seesaw structure. The oil cylinder 9 drives the clamping cross arm 6 to rotate, which can provide sufficient space for the clamping and disassembly of the workpiece to be processed. At the same time, the lifting force of the oil cylinder 9 can be converted into a clamping force on the part to be processed 11 through the clamping cross arm 6.

[0028] The cushion block 5 is arranged just below the welding point. Before welding, the oil cylinder 9 is adjusted to the movable pressing plate 7 to press the part to be processed 11, and the part to be processed 11 is kept in a horizontal state.

[0029] The fixed clamping mechanism includes a positioning block 2 and a fixed pressure plate 3. The positioning block 2 includes a horizontal part connected to the support platform 1 by bolts and a vertical plate fixedly connected to the horizontal part. Since the processing is batch production, the size of a batch of parts 11 to be processed is fixed, and different parts 11 to be processed can be adapted by designing vertical plates of different heights.

[0030] In order to reduce the disassembly work and adapt to the parts 11 to be processed with different welding points or multiple welding points, a slide groove 12 parallel to the long side of the support platform 1 is opened on the upper part of the support platform 1, and the pad 5 is penetrated by a countersunk bolt passing through the pad 5 and the slide groove 12; the position of the sliding pad 5 is adapted to the welding points in different positions.

[0031] The fixation and sliding of the pad 5 can be controlled by tightening and loosening the countersunk bolts. The countersunk bolts can be rotated to keep the pad 5 and the support platform 1 relatively fixed. This can be achieved by common methods such as opening a plurality of threaded holes at the bottom of the slide groove 12 that cooperate with the countersunk bolts.

[0032] In order to improve the welding accuracy and prevent the part to be processed 11 from being displaced or deformed in the horizontal direction, a limiting mechanism 4 for limiting the part to be processed 11 in the horizontal direction is also provided on the upper part of the support platform 1. The limiting mechanism 4 includes a fixed limiting block 41, a limiting adjustment block 42, and a connecting plate 43, the thickness of which is less than the thickness of the cushion block 5; the connecting plate 43 is connected to the upper part of the support platform 1 and is perpendicular to the long side of the support platform 1, and both ends of the connecting plate 43 extend outward beyond the edge of the support platform 1, and one end of the upper part of the extension of the connecting plate 43 beyond the edge of the support platform 1 is fixedly connected with the fixed limiting block 41, and the other end is fixedly connected with the limiting adjustment block 42, and the limiting adjustment block 42 includes a protruding portion and a screw rod that is threadedly matched with the upper part of the protruding portion, and by rotating the screw rod, the front end of the screw rod is pressed against the side wall of the part to be processed, thereby limiting the part to be processed 11 in the horizontal direction.

[0033] When in use, first adjust the oil cylinder 9 to the retracted state, lift the sliding platen, place the part to be processed 11 on the cushion block 5, and place one end of the part to be processed 11 on the lower part of the fixed platen 3;

[0034] Then the oil cylinder 9 is adjusted to an extended state until the movable pressing plate 7 presses the workpiece 11 to be processed, and the workpiece 11 to be processed remains in a horizontal state;

[0035] Then, the screw of the limiting mechanism 4 is rotated to position the part 11 to be processed in the horizontal direction; then welding can be carried out; the steps are reversed when disassembling. The utility model limits the deformation of the strip long arm during welding by pre-pressing, avoids subsequent measurement and correction, saves procedures and working hours, and improves efficiency.

[0036] Except for the technical features described in the specification, all other technical features are known to those skilled in the art.
