The first upper positioning block 600 is mainly used for positioning the front and rear positions of the main body plate 110 on the platform 210, in actual operation, the main body plate 110 is placed on the platform 210, the main body plate 110 is pushed forward, and when the front side surface of the first upper positioning block 600 abuts against the rear side surface of the main body plate 110 (the front side surface of the first upper positioning block 600 is substantially parallel to the rear side surface of the main body plate 110), the main body plate 110 cannot move forward any more, so that the front and rear positions of the main body plate 110 on the platform 210 can be positioned. The first side positioning block 510 is mainly used for positioning the left and right positions of the main body plate 110 on the platform 210, and in actual operation, the main body plate 110 is placed on the platform 210, the main body plate 110 is pushed to the left, and when the right side surface of the first side positioning block 510 abuts against the left side surface of the main body plate 110 (the right side surface of the first side positioning block 510 is substantially parallel to the left side surface of the main body plate 110), the main body plate 110 cannot move to the left any more, so that the left and right positions of the main body plate 110 on the platform 210 can be positioned. It should be understood that, when the front and rear positions of the main body plate 110 are first located and then the left and right positions of the main body plate 110 are located, in order to prevent the main body plate 110 from moving backward, a force is generally applied obliquely to the left upper corner to push the main body plate 110 to move left; when the left and right positions of the main body plate 110 are first located and then the front and rear positions of the main body plate 110 are located, the main body plate 110 is pushed forward by applying a force obliquely to the left upper corner to prevent the main body plate 110 from moving rightward. It should be understood that the positioning blocks (the first upper positioning block 600 and the second upper positioning block 520) for positioning the front and rear positions of the plate members (the main body plate 110 and the side plate 120) are positioned by using the front side surfaces (i.e. the positioning blocks are located at the positions behind the platform 210), so that the front push plate member is convenient to position for the operation of the worker; although the positioning blocks (the first side positioning block 510 and the second side positioning block 700) for positioning the left and right positions of the plate members (the main body plate 110 and the side plate 120) are all positioned by using the right side surface (i.e. the positioning blocks are located at the left position of the platform 210), it is to be noted that the left and right directions are only for convenience of description, and even if the positioning blocks are positioned by using the left side surface (i.e. the positioning blocks are arranged at the right position of the platform 210), the same functions as those of the positioning blocks in the present invention can be achieved, which is a simple replacement of the embodiment of the present invention.

The second upper positioning block 520 is mainly used for positioning the front and rear positions of the side plate 120 on the platform 210, in practical operation, the side plate 120 is placed on the platform 210, the side plate 120 is pushed forward, and when the front side surface of the second upper positioning block 520 abuts against the rear side surface of the side plate 120 (the front side surface of the second upper positioning block 520 is substantially parallel to the rear side surface of the side plate 120), the side plate 120 cannot move forward any more, so that the front and rear positions of the side plate 120 on the platform 210 can be positioned. When the side plate 120 is pushed to the right, when the left side surface of the main body plate 110 abuts against the right side surface of the side plate 120 (the left side surface of the main body plate 110 and the right side surface of the side plate 120 are spliced together to form a connecting gap 130), the side plate 120 cannot move to the right any more, so that the left and right positions of the side plate 120 on the platform 210 can be positioned. It should be understood that the side plate 120 is also obliquely pushed in practice. It should be understood that, in actual practice, the main body plate 110 is positioned first, and then the side plate 120 is positioned. It is to be understood that after the main body plate 110 and the side plate 120 are positioned, tack welding (tack welding) may be performed to assist the next welding work. It should be understood that the first upper positioning block 600, the second upper positioning block 520, the first side positioning block 510, and the second side positioning block 700 are collectively referred to as positioning blocks for convenience of description.

Since the positioning block is fixed in position on the platform 210, and the sizes of the main body plate 110 and the side plate 120 are not changed in the water tank of the same specification, through the above positioning work, each time the welding work is performed, the connecting gap 130 of the main body plate 110 and the side plate 120 is located at a specific position on the platform 210, and the specific position is kept unchanged, so that the moving mechanism 400 can drive the welding gun 300 to weld the connecting gap 130 according to a predetermined program, the welding work can be repeated, the welding efficiency is high, and the welding quality is stable.

Referring to fig. 1 to 5, in some embodiments of the present invention, a second side positioning block 700 is further included, the second side positioning block 700 is disposed on the platform 210, the second side positioning block 700 is located in front of the first side positioning block 510, and a right side surface of the second side positioning block 700 is configured to abut against a left side surface of the main body plate 110.

Since the main body plate 110 needs to be divided into the bottom plate 111 and the two side plates 112 above and below the bottom plate 111, the main body plate 110 is generally a rectangular long and narrow plate, and therefore, the left and right sides of the main body plate 110 are long, and therefore, the right side of the first side positioning block 510 is small relative to the left side of the main body plate 110, and if only the first side positioning block 510 is used to position the main body plate 110, the positioning accuracy may be poor and the error may be large. The second side positioning block 700 is arranged to assist in positioning the main body plate 110, so that the positioning accuracy of the main body plate 110 can be improved, the positioning error is small, and the welding quality of the plate is improved.

Referring to fig. 1 to 5, in some embodiments of the present invention, a general locating block 500 is further included, the general locating block 500 is disposed on the platform 210, and the general locating block 500 includes a first side locating block 510 and a second upper locating block 520.

Since the second side positioning block 700 is disposed in front of the first side positioning block 510, the first side positioning block 510 and the second upper positioning block 520 are disposed at the upper left corner of the main body plate 110, and are closer to each other. It is possible to use only one overall positioning block 500 to perform the functions of the first side positioning block 510 and the second upper positioning block 520, i.e., the overall positioning block 500 includes the first side positioning block 510 and the second upper positioning block 520; the front side of the general positioning block 500 is the front side of the second upper positioning block 520, and the right side of the general positioning block 500 is the right side of the first side positioning block 510. The positioning effect of the main body plate 110 and the side plate 120 is affected by the machining error (the error of the parallelism of the side surfaces of the positioning blocks) of the first side positioning block 510 and the second upper positioning block 520, the absolute position error (the error of the absolute value of the coordinate of the central point of the positioning block on the platform 210) mounted on the platform 210, the relative position error (the error of the relative value of the coordinate of the central points of the two positioning blocks on the platform 210) mounted on the platform 210, and the form error (the positioning block may rotate and deflect around the central point) mounted on the platform 210; and only one general positioning block 500 is used to realize the functions of the first side positioning block 510 and the second upper positioning block 520, so that the relative position error mounted on the platform 210 does not need to be considered, and other error variables are changed from two superposition into only one, thereby greatly reducing the range of the general error and enabling the positioning of the main body plate 110 and the side plate 120 to be more accurate.
