Description
Technical field
The present invention relates to hydraulic support connecting rods, more particularly, to the automation butt welding method of hydraulic support gonnecting rod body.
Background technology
Hydraulic support is as main support apparatus in coal-mine integrated-mining equipment, and with volume and weight, big, service condition is disliked
Bad, the features such as box welding structure is more.Gonnecting rod body is the important feature part of hydraulic support, and a gonnecting rod body is generally by 2 main reinforcements
Plate, 4 pasting boards, 1 bottom plate, 2 gussets and 1 cover board are constituted.Currently, the manufacture of hydraulic support connecting rod is mainly by artificial crossed
It is assembled；All parts are inspected by random samples before assembled, assembled benchmark is mainly assembled on the basis of one end of gonnecting rod body main reinforcement；Even
The logistics of body of rod assembly to welding uses artificial handling, is preheated respectively after the completion of a spelling component, cover board are assembled, amounts to preheating two
It is secondary.Currently, the technological process of production of hydraulic support gonnecting rod body is：One, which spells component → preheating → mono-, spells components welding → cover board assembly
→ preheating → gonnecting rod body outside weld seam welding.
The production of above-mentioned hydraulic support gonnecting rod body has the following disadvantages：1, due to artificial assembled, assembled precision is low, crucial
Size disunity influences the appearance of connecting rod and follow-up assembly；2, assembled gap size differs, when gap is excessive, after causing
Continuous welding robot weldering leakage or weld seam height differ；When gap is too small, leads to occur assembled interference fire and cut phenomenon, the amount of reprocessing
Greatly；3, positioning datum is unreasonable：Assembled benchmark and subsequent overall processing benchmark disunity, influence subsequent bore hole and assembly；
4, technological process is complicated, needs to preheat twice, needs process to transport between a spelling components welding and cover board assembly, causes energy consumption unrestrained
Take and influences production efficiency.
