Background
The extensive numerous fields such as boiler, chemical industry equipment that are used for of tube sheet formula heat exchanger, this kind of heat exchanger main part comprises a plurality of pipes that are parallel to each other and two steel sheets, and pipe and steel sheet welding during the welding, penetrate the pipe both ends in the corresponding hole of steel sheet and make relatively fixed between the two, then adopt manual welding, and at present, heat exchanger tube sheet welding is accomplished by the manual work basically, mainly because two aspects: 1. the steel plate can generate deformation after a plurality of working procedures during processing, and the height difference between the highest point and the lowest point of the steel plate is more than 5 mm; 2. the welding seam clearance between the round pipe and the steel plate is different in size, the largest welding seam is 5mm, and the smallest welding seam is 1 mm. Therefore, if a welding robot on the market is adopted, each welding seam needs to be taught, the efficiency is too low, the use of automatic welding is completely limited, the manual welding efficiency is low, the cost is high, if the automatic welding is realized, the welding track of the welding position of each pipe and a steel plate can be accurately and efficiently realized, the measuring arm technology developed by the applicant can be used for producing the welding track through calculating by collecting the space coordinates of three points on the welding seam for a circular welding seam, but the mode needs to measure three points for each circular pipe, and another circular pipe is measured after one circular pipe is welded, although the welding is carried out by the robot, the mode also needs a worker to continuously measure and then carry out the measurement by equipment, and the efficiency is not obviously improved.
Disclosure of Invention
The utility model aims to overcome the problems in the prior welding of the heat exchanger tube plate and provides an array type efficient automatic welding tool for the heat exchanger tube plate.
In order to realize the purpose of the utility model, the following technical scheme is adopted: the array type efficient automatic welding tool for the tube plate of the heat exchanger comprises a circumferential surface at the lower part, the diameter difference between the inner diameter of a round tube on the heat exchanger and the circumferential surface is less than or equal to 0.8mm, a supporting plate is integrally or fixedly connected onto the circumferential surface, the maximum distance between two points on the edge of the supporting plate is greater than the inner diameter of the round tube, at least three supporting legs with the same height are fixedly connected onto the supporting plate, the three supporting legs are distributed in a triangular shape, a mark point is arranged on the supporting plate, and the mark point is located on the axis of the circumferential surface.
Further, the method comprises the following steps of; the mark point is a conical bulge with a small upper part and a big lower part, and the axis of the cone is superposed with the axis of the circumferential surface.
Further, the method comprises the following steps of; the supporting plate is a disc plate.
Further, the method comprises the following steps of; three screw holes are uniformly distributed along the center on the supporting plate, and three equal-height supporting legs are screwed in the screw holes.
Further, the method comprises the following steps of; the circumferential surface and the supporting plate are of a split structure, a screw rod is arranged on the lower end face of the supporting plate, a threaded hole is formed in the upper end face of the circumferential surface, and the threaded hole is connected with the screw rod in a screwing mode.
Further, the method comprises the following steps of; the diameter difference between the inner diameter and the circumferential surface of a circular pipe on the heat exchanger is less than or equal to 0.6 mm.
The utility model has the positive and beneficial technical effects that: in the welding of heat exchanger tube sheet, insert the periphery of this frock in the pipe, can obtain the peripheral welding seam orbit parameter of pipe through measuring arm measurement mark point position, particularly, if the steel sheet is the horizontal plane, then accessible centre of a circle coordinate, the stabilizer blade height, the welding orbit of welding seam is obtained to the pipe external diameter, if the steel sheet is the inclined plane, accessible centre of a circle coordinate, stabilizer blade and backup pad height, the pipe external diameter, the gradient of steel sheet obtains the welding orbit of the peripheral welding seam that corresponds of each pipe, welding robot can be based on welding orbit and welding parameter one by one the welding of the completion of each welding seam after having the welding orbit, can realize heat exchanger array tube sheet automatic weld.

Detailed Description
In order to more fully explain the implementation of the present invention, examples of the implementation of the present invention are provided. These examples are merely illustrative of the present invention and do not limit the scope of the present invention.
The utility model is explained in further detail in connection with the accompanying drawings, in which: 1: a circumferential surface; 2: a support plate; 3: a support leg; 4: a conical projection; 5: a screw; 6: a circular tube; 7: and (3) a steel plate.
As shown in the attached drawing, the heat exchanger tube plate array type efficient automatic welding tool comprises a circumferential surface 1 at the lower part, the diameter difference between the inner diameter and the circumferential surface of a circular tube 6 on a heat exchanger is less than or equal to 0.8mm, and preferably, the diameter difference between the inner diameter and the circumferential surface of the circular tube on the heat exchanger is less than or equal to 0.6 mm.
The circumferential surface is integrally or fixedly connected with a supporting plate 2, and the maximum distance between two points on the edge of the supporting plate 2 is larger than the inner diameter of the circular pipe. The supporting plate is a disc plate. The disk plate is concentric with the circumferential surface.
