[0047] The present invention also provides a construction method of the robot arc welding workstation for template welding, comprising the following steps:

[0048] A. Clean the tabletop 11 of the welding platform 1, prepare the support 4, the first chuck 6, the second chuck 7 and the template M with the material placed;

[0049] B. Place the template M on the table top 11, align the edge of the template with the grid on the table top 11, and align one long side and one short side respectively; fasten the support member 4 on the table top 11 and fix it outside the template M, so that the support member 4 is perpendicular to the table top 11;

[0050] C. Place the upper strip plate, rib plate and lower strip plate; place the first clamp 6 at the corresponding position of the support member 4; first tighten the first clamp 6 corresponding to the middle rib plate; then place the rib plates at both ends between the upper and lower strip plates, and tighten the corresponding first clamp 6; check the plane verticality and facade verticality of the rib plate, tap and fine-tune the position of the rib plate; further, fix two first clamps 6 on the outside of the short side of the template M, and fix one first clamp 6 at a spacing of 400-500mm on the long side;

[0052] E. Program according to the welding robot 3 operating procedure requirements and simulate the welding operation process; after confirmation, start the automatic welding process.

[0053] The tightening process of the support member 4 is as follows: the second plate 42 of the support member 4 is tightly attached to the upper surface of the table panel 11, the positioning rod 51 of the fixing member 5 passes through the oblong hole 421 of the second plate 42, and is inserted into the positioning hole 12 of the table panel 11, and the nut 53 is rotated. As the nut 53 is tightened, the screw rod 52 moves downward, and the bottom steel ball 54 is pushed out and pressed against the inner wall of the positioning hole 12 of the table panel 11.

[0054] When the positioning rod 51 of the fixing member 5 is too long, a cushion layer is placed on the second plate 42 , and the cushion layer is provided with a through hole corresponding to the long hole 421 , so that the steel ball 54 of the fixing member 5 is located on the inner wall of the positioning hole 12 .

[0055] The present invention adopts a vertical flip positioner and a welding robot to manually assemble and clamp the template components on the table panel of the welding platform using a support, a first clamp, and a second clamp, and the robot automatically welds all welds; two welding stations can be set up in a symmetrical arrangement, and when one station is welding, the other station loads and unloads workpieces, and the cycle is in sequence. The welding robot takes turns welding at the two stations, which greatly improves the work efficiency.

[0056] The present invention adopts a welding robot to realize full automation of the processing process, reducing the labor intensity of workers. The welding robot teaching programmer is a 6.5-inch color touch screen with Chinese display, which is easy to operate. The motion trajectory of the welding robot can be taught, and it can complete the motion of any path in space; it can store multiple sets of programs at the same time, corresponding to products of various specifications. The welding robot has zero point memory, process memory and return functions. The control system is controlled by PLC and has functions such as automatic control, detection, protection, and alarm. When the specifications of the workpiece or the production program change, different programs can be selected on the operating panel to adapt to new production needs. Emergency stop buttons are provided on the robot control cabinet (DX200), teaching box, operating panel and operating box. When an emergency occurs in the system, the system can be stopped by pressing the emergency stop button and an alarm signal can be issued at the same time.

[0057] The welding positioning fixture (support, fixing, first chuck, second chuck) of the present invention is a modular, standardized, reusable, and widely applicable new welding fixture for welding, machining, and testing workpieces. It is based on a workbench with grid holes and a ruler, equipped with various standard modules for positioning, connected by fixings, and can quickly clamp workpieces of various shapes to ensure that the welded or processed workpieces reach a very high precision. It replaces the traditional special fixture, allowing users to not only shorten a large amount of design and manufacturing time, but also can be used repeatedly, saving research and development and production costs, and is a very economical and practical choice. The welding positioning fixture (support, fixing, first chuck, second chuck) of the present invention is a fixture that can be freely combined and can adapt to different workpiece shapes. Several sets of fixture systems can replace a large number of high-cost special fixtures. After using the fixture, the cost and time of special fixtures invested due to product changes can be saved. In the production of multi-variety and personalized molds, its economy is particularly obvious.

[0058] The table top of the present invention adopts a cast iron platform, which has the following characteristics:

[0059] 1. After the cast iron platform is worn out, it can be scraped again to restore its accuracy.

[0060] 2. The cast iron platform can be used to check the flatness of parts by coloring, which has the advantages of accuracy, intuitiveness and convenience. Pushing the table seat and workpiece on the scraped cast iron platform is relatively smooth, without astringency, which facilitates measurement and ensures measurement accuracy.

[0061] 3. The quality of cast iron and heat treatment of cast iron platform has a great influence on the performance of the plate: the working surface may be deformed due to the large residual internal stress; the precision cannot be maintained due to the wear resistance; or the roughness with small value cannot be obtained due to the difficulty of scraping. Therefore, when using cast iron platform, attention must be paid to the selection of cast iron material, and the residual stress of cast iron platform should be eliminated by aging treatment and other methods.

[0062] The above embodiments may be modified in some ways without departing from the scope of the present invention. Therefore, the above description should be regarded as illustrative rather than limiting the scope of protection of the patent application of the present invention. All technical solutions under the concept of the present invention belong to the scope of protection of the present invention.
