drawings

2 and 3, the following front and rear parts refer to the right and left parts of the attached

2 and 4, and the following left and right parts refer to the left and right parts of the attached drawings 3. The upper, lower, front, rear, left and right are only used for describing the structure of the utility model and are not used as the limitation of the utility model. The fixed connection described below may be a weld, a fastener connection, or a unitary structure.

The brazing tool is designed by fully utilizing the structural characteristics of the plowshare. The tool comprises a workbench 6, a moving block 8, a rotating shaft 10, a supporting plate 2, a pin shaft 11, a positioning rod 4, a positioning support 5 and the like. The worktable 6 is groove-shaped, and a plurality of rotatable balls 7 are embedded on two sides of the bottom of the groove. The moving block 8 is placed in the groove, supported by the small ball 7, and can move in the front-rear direction of the groove. A vertical rotating shaft 10 is installed on the moving block 8, and the rotating shaft 10 is rotatably connected with the moving block 8, is fixed in the vertical direction and can rotate freely. In this embodiment, in order to facilitate the rotation of the rotating shaft, a bearing 9 is used to connect with the moving block 8 at the lower part of the rotating shaft 10. The upper part of the rotating shaft 10 is fixedly provided with a pin shaft 11, the pin shaft 11 is hinged with a support frame, and the support frame can freely rotate around the pin shaft 11. Or the support frame is integrated with the pin shaft 11 and hinged with the rotating shaft 10. The free rotation of support frame can both be realized to two kinds of connected modes.

The support frame is formed by fixedly connecting two V-shaped support plates 2 through two positioning blocks 12 at the front side and the rear side into a whole, and is of a rotational symmetric structure, as shown in figure 4. The pin shaft is positioned at the bottom of the V shape. The distance between the two supporting plates 2 corresponds to the thickness of the rib plate of the plowshare, and when the plowshare 1 slides into the two supporting plates 2, the positioning block 12 can realize the positioning of the plowshare. The outer sides (the inner side and the outer side, relative to the positions of the two support plates) of the support plates 2 are fixedly connected with positioning arc plates 3, the supporting surfaces of the positioning arc plates 3 are slidably connected with the upper ends of positioning rods 4, the lower ends of the positioning rods 4 are hinged with positioning brackets 5, and the positioning brackets 5 are fixed on movable blocks 8. As shown in fig. 1, the positioning arc plate 3 is designed with two limiting positions in tandem to limit the sliding position of the positioning rod 4. When the positioning rod 4 rotates clockwise and slides to the front end of the positioning arc plate 3, the inclined plane of the plowshare A in the front part of the rotating shaft 10 is a horizontal plane, the inclined plane of the plowshare B in the rear part of the rotating shaft 10 is a horizontal plane, and meanwhile, the supporting stress direction of the positioning rod 4 is vertical to the supporting surface of the positioning arc plate 3. When the positioning rod 4 rotates anticlockwise and slides to the rear end of the positioning arc plate 3, the inclined plane of the plowshare B in the front of the rotating shaft 10 is a horizontal plane, the inclined plane of the plowshare A in the rear of the rotating shaft 10 is a horizontal plane, and similarly, the stress direction of the positioning rod 4 is vertical to the supporting surface of the positioning arc plate 3.

When the utility model is used, two plowshare are placed on the support frame, the rotating shaft 10 is rotated to enable the positioning arc plate 3 to correspond to the positioning rod 4, and then the support frame is rotated around the pin shaft 11 to enable the positioning rod 4 to be matched with the positioning arc plate 3. Rotating the positioning rod 4 to the front end of the positioning arc plate 3, enabling the A inclined plane to be horizontal, moving the moving block 8 forwards along the direction of the groove of the workbench 6, entering a brazing station of a first brazing machine, and brazing the wear-resistant sheet on the A inclined plane. After the wear-resistant pieces on the inclined surface A are brazed and fixed, the positioning rod 4 is rotated anticlockwise to the rear end of the positioning arc plate 3, the inclined surface B is horizontal, the position of the moving block 8 is adjusted forwards and backwards, the moving block enters a brazing station of a second brazing machine, and the wear-resistant pieces on the inclined surface B are brazed. After one plowshare is brazed, the supporting frame is rotated to separate the positioning rod 4 from the positioning arc plate 3, then the rotating shaft 10 is rotated to rotate the second plowshare to the position of the previous plowshare, and the operations are repeated to braze the wear-resistant pieces on the inclined surfaces A and B of the second plowshare. The two plowshares are mutually balanced on the supporting frame, so the labor is not required to rotate the supporting frame. When the positioning rod 4 is at the limit position at the two ends of the positioning arc plate 3, the supporting force direction of the positioning rod is perpendicular to the supporting surface of the positioning arc plate 3, and when the front moving block 8 moves backwards or the wear-resistant plate is brazed, the supporting frame can be kept relatively stable.

The embodiment adopts the groove of the workbench 6 to limit the moving block 8 to move back and forth so as to ensure the moving direction, and can also adopt other positioning and moving structures, such as a dovetail groove, a guide post, a guide rail and the like. The above-mentioned embodiment uses the ball 7 to roll to realize the movement of the moving block 8, and may also use the sliding and small wheel moving methods, and the improvement of the above-mentioned moving block 8 moving structure by using the prior art is all in the protection scope of the present invention.

The utility model fully utilizes the structural characteristics of the plowshare, can realize the continuous brazing of the A, B inclined-surface wear-resisting pieces of the two plowshares, not only quickens the brazing rhythm and greatly saves the auxiliary time, but also reduces the labor intensity of operators by a half, and changes the previous brazing of one inclined-surface wear-resisting piece into the brazing of two inclined surfaces for once. Because the A, B slope level elevation of same ploughshare is different, and induction coil fixes the upper segment at the brazing machine, so need two brazing machines to use together.
