AI Technical Summary

Problems solved by technology

The existing welding method is manual welding, the welding efficiency is low, and there is a large error in the welding position, including the error in the position of the welding point between the steel bar and the steel frame, that is, the error between the parallel steel bars, and the error between each steel frame. The error of the distance, the product quality is poor
There are also some technologies that use a welding machine with a welding torch to weld each steel bar and steel frame one by one, which still cannot solve the above-mentioned problems of low welding efficiency and large welding spot errors

Embodiment 1

[0083] The feeding step of steel frame 10a:

[0084] Step 1. Start the lifting motor 4b to lower the material rack. After it falls, the distance between the upper material rack 51 and the lower material rack 52 is less than the vertical height of the inner frame of the steel frame 10a, specifically the angle beam 5e and the joist The distance between 5g is less than the inner frame vertical height of steel frame 10a;

[0085] Step 2. Transport a plurality of steel frames 10a distributed forward and backward to the material rack 5 through a forklift or other upstream machinery. The state after loading is that the bottom of the steel frame 10a is mounted on the joist 5g, the angle beam 5e is set in the steel frame 10a;

[0086] Step 3. If the distance between the angle beam 5e and the joist 5g is obviously smaller than the vertical height of the inner frame of the steel frame 10a, the steel frame 10a will have a relatively large inclination. At this time, start the lifting moto...

Embodiment 2

[0092] The loading steps of steel bar 10b:

[0093] Adjust the position of the line pipe 5i in the feeding rack 51. If the distance between the steel bars 10b on both sides is relatively close, and the left and right width difference between the inner frame of the steel frame 10a is large, it will cause the welding assembly to be unable to complete the fixing of the steel bars. Therefore, It is necessary to adjust the position of the wire pipe 5i so that it is close to the left and right width of the inner frame of the steel frame 10a,

[0094] Step 1. Loosen the bolts on the upper end of the mounting block 5f;

[0095] Step 2. Move the mounting block 5f in the left and right direction, so as to adjust the position of the wire pipe 5i through the angle beam 5e;

[0096] Step 3. Tighten the bolts on the top of the mounting block 5f to complete the fixation;

[0097] In the same way, adjust the position of the wire-passing pipe 5i in the blanking rack 52 to adjust,

[0098] S...

Embodiment 3

[0107] In embodiment 2, the feeding steps of 4 steel bars are described. If it is necessary to complete the feeding of more steel bars, it is necessary to install a plurality of upper channel steel 5b with passing beams 5k. The specific steps are:

[0108] Finish step 1-step 8 in embodiment 3;

[0109] Step 1, fixing the screw rod 5c and the uppermost upper channel steel 5b through nuts;

[0110] Step 2. Take another upper channel steel 5b, and put the wire passing beam below it on the two left and right screw rods 5c;

[0111] Step 3, insert the cotter pin 5d at a suitable height; adjust the height of the crossing beam 5k through the height of the cotter pin 5d, and finally adjust the height of the added reinforcing bar 10b;

[0112]Step 4, put down the added upper channel steel 5b, so that the wire passing beam 5k is mounted on the cotter pin 5d;

[0113] The above steps are recommended to be completed before loading the steel frame 10a, because the steel frame 10a after l...

Abstract

The invention discloses a beam column welding robot which comprises a feeding portion and a welding portion, wherein the feeding portion and the welding portion are connected through a fixing beam, the feeding portion carries workpieces and specifically comprises a plurality of steel frames distributed in a rectangular array mode in a front-back direction and at least four steel bars located at the four corners of the steel frames of a rectangular structure. The beam column welding robot has the beneficial effects that welding of one steel frame and all the steel bars is completed at the same time, carrying of all the steel frames is completed at one time, the steel frames are conveniently fed one by one, and the welding efficiency is improved; adjustment on a welding gun is achieved through numerical control of a servo motor, the positions of the welding gun, the steel bars and the steel frames are grasped through a plurality of air cylinders during welding, and the welding spot positions are accurate; and after welding, movement of the steel bars in the front-back direction is completed through numerical control of the servo motors, the positions of all the steel frames are accurately positioned, and the quality of welded products is integrally guaranteed.

Description

technical field [0001] The invention relates to the field of metal processing machinery, in particular to a beam and column welding robot. Background technique [0002] Beam-column welding refers to a rectangular steel frame, running through the steel bars in the frame, and then welding the steel bars to the left and right inner walls of the steel frame. According to the different requirements of the workpiece, the number of welded steel bars is also different. The existing welding method is manual welding, the welding efficiency is low, and there is a large error in the welding position, including the error in the position of the welding point between the steel bar and the steel frame, that is, the error between the parallel steel bars, and the error between each steel frame. The error of the distance between them, the product quality is poor. There are also some technologies that weld each steel bar and steel frame one by one through a welding machine with a welding torc...
