Detailed Description

The embodiment of the application provides a welding test plate groove machining device, and solves the technical problems of insufficient machining efficiency and quality of welding test plates in the related technology.

In order to solve the technical problems, the general idea of the embodiment of the application is as follows:

the utility model provides a welding test panel groove preparation device, includes mount, aircraft nose and running gear, and the mount is equipped with the draw-in groove, and the draw-in groove is used for the clamping to be a plurality of test panels of treating processing that row was arranged, and the aircraft nose is equipped with milling cutter and motor power, and motor power is used for carrying out angle fine-tuning and the fine-tuning of depth of feed to milling cutter, and milling cutter installs in running gear, and running gear can follow the array direction removal of test panel.

In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.

In different fields, different methods exist for welding modes due to different requirements, different materials and different welding modes. The welding has higher requirements on welders, has strict requirements on welding grooves and end faces, and particularly for high-strength steel plates, the welders need to be trained before welding, the welding state is simulated, and the test plate 180 is subjected to simulated welding. The welding test plate 180 is required to be consistent with the product welding process in a simulation state, and the groove of the test plate 180 is processed before welding. No special test plate 180 processing equipment is arranged in the machining process, and a universal planer and a large-scale milling machine are adopted for operation.

The welder training is a foundation stone for enterprise development, and besides training newly-entered welders, the welder training also needs to retrain old welders every two years. New products and new materials are welded and evidence is obtained. In order to satisfy the welder training work, a large number of welding test plates 180 are required to be processed every year. Because the process requirements are different, the groove forms of the welding seams at different stations are different, and the groove angles are different from 20 degrees to 50 degrees.

The inventors summarized and analyzed the processing manner of the welding test plate 180 in the related art, and found the following:

if a shaping machine is adopted for processing, 18 test plates 180 are processed averagely every day, each test plate needs 25 minutes, the processing surface is not formed well, and only 14 test plates reach the standard. The processing speed cannot meet the requirement, the transfer workload of the test plate 180 is large, no hoisting equipment is arranged in an infield, and the test plate is carried by manpower;

if a floor boring machine is adopted, the forming is good after the processing of one block needs 12 minutes. The floor boring machine is large in bed body and suitable for machining large workpieces, the test plates of machining &28 x 125 x 300 and &28 x 125 x 600 are complex to operate, and each test plate is measured and clamped; when one test plate 180 is machined, the test plate needs to be replaced frequently, the machining efficiency cannot be improved, the production requirement cannot be met, and the production technical requirement cannot be met;

if a bicycle type beveling machine is adopted, the design for processing large steel plates is not suitable for processing small test plates 180; because test panel 180 length 300 millimeters, bicycle formula beveling machine centre gripping mode is different, need pass through the seam of two steel sheets, because test panel 180 centre gripping, it is portable through the gyro wheel operation, at processing initial stage and later stage, the gyro wheel walking, need pass through test panel 180 seam, only unilateral pinch roller work, during the processing groove, appear test panel 180 shake from top to bottom, only one side pinch roller work, cause test panel 180 shake phenomenon appear in the course of working, milling cutter 210 pieces often appear damaged, the consume is higher. The two ends of the test plate 180 are not well formed, and potential safety hazards exist; the machining cannot be carried out back and forth (the machining runs in one direction); the clamping of the test plate 180 is nonstandard, the accurate operation is difficult, the clamping is loose and tight, the control is not possible, the blade is easy to damage due to the loose clamping, and the walking is impossible due to the tight clamping; the processing depth of the groove of the test plate 180 is different, the processing quality and the processing precision can not be ensured.

In the angle groove machining, the machine head 200 can realize the adjustment of 0-60 degrees, and in one embodiment, the designated angle can be selected to be 30-50 degrees.

Based on the welding test plate 180 groove processing method, the following processing modes can be referred to by combining the welding test plate 180 groove processing device:

sequentially placing the test panels 180 subjected to flame blanking into the slots 171 of the test panels 180 according to a certain arrangement, relying on a bottom base plate 160, screwing a compression bolt 130 and compressing a cushion block 140 to tightly connect the test panels 180 with the first base plate 150;

after the test plate 180 is fixed, the second hand wheel 630 is adjusted, so that the connecting plate 440 drives the power head to move up and down along the fixed rail 110 of the adjusting upright column 620 to reach a proper position;

then adjusting the first hand wheel 510, adjusting the horizontal angle between the head of the power head milling cutter 210 and the test plate 180 to make the milling cutter face of the milling cutter 210 and the end face of the test plate 180 form an angle of 0 degree, adjusting the first hand wheel 510 again to adjust the depth of feed, starting the motor, and operating the motor to perform machining at 0 degree;

after the machining of 0 degree is finished, adjusting a first hand wheel 510 to match with a power motor 220 to enable the milling cutter 210 to reach a specified angle, and moving back to perform angle groove machining, wherein the groove can be machined in place at one time;

in the process of back and forth operation of the beveling machine, the processes of 0-degree machining and beveling can be realized, and the machining efficiency is greatly improved. And the multi-time processing is realized by one-time clamping, so that the efficiency is improved, the quality is improved, and the technical requirement of welding the test plate 180 is met.
