Description
Technical field
Ball mill end covers welding procedure, belongs to tank body welding technical field.
Background technology
Ball mill end covers is the critical piece of ball mill, the main shaft of ball mill end covers center is that the firmness of main shaft welding and precision directly determine function and the service life of ball mill itself by the critical component of the power set connection for transmission of ball mill and ball mill.Current ball mill end covers welding process, in order to the shortening flow process of trying one's best, the technique of disposable welding is manually carried out in basic employing, when the welding of gusset, stiffener, main shaft and end covers, after workman manually locates, directly by each parts welding completely, the operation of workman does not reach unified standard, and welding efficiency is low, welding quality is unstable.Along with the development of society, the drawback of manual welding also displays day by day, and such as welding level is many, pore is many, weld interval is long, causes the end socket of postwelding can't meet the quality requirement, and loses larger.Lack a kind of suitable technological process at present, make ball mill end covers weld the process adapting to automation, to enhance productivity.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, provides that a kind of production efficiency is high, welding uniform specification ball mill end covers welding procedure accurately.
The technical solution adopted for the present invention to solve the technical problems is: this ball mill end covers welding procedure, and it is characterized in that, welding step is:
1) be first fixed on the vertical positioner arranged by the main shaft through end covers by opening up for end covers; Gusset is placed on the position to be welded in end covers, utilizes welding robot to carry out spot welding location at the contact point of the contact point of gusset and end covers, gusset and main shaft simultaneously; After starting the angle set between positioner rotation gusset, then another block gusset is placed on next position to be welded in end covers, repeats aforesaid operations until whole for the gusset of end covers design quantity spot welding completed;
2) end covers gusset spot welding completed is opening down to be buckled on smooth workbench, be enclosed within by stiffener on the main shaft outside end covers, the circumference that the circumference utilizing welding robot to be contacted with main shaft by stiffener and stiffener contact with end covers carries out the end covers that seal welding obtains being welded with stiffener respectively again;
3) utilize horizontally disposed positioner and the clamping piece relative with this positioner by relatively clamping for the main shaft being welded with the end covers of stiffener, after the arbitrary gusset utilizing positioner by end covers turns to level, welding robot is utilized to carry out seal welding to the gusset of this level, then next gusset of end covers is turned to level by positioner, welding robot proceeds welding, until all gussets and end covers all complete seal welding.
All gussets and end covers are first carried out spot welding by welding step of the present invention, realize calibration location, during spot welding, positioner is vertically arranged, the corresponding opening of end covers vertically upward, what be convenient to gusset ajusts placement, ensure that calibration location is easier, be convenient to realize welding and be transported through robot automatically completing, stiffener is welded between end covers and main shaft, strengthen the entirety of end covers by force intensity, main shaft can be utilized in step 3) by whole end covers horizontal positioned, now recycle welding robot and carry out seal welding, the action that completes needed for welding robot can be made simpler, be convenient to utilize simple programme-control, reduce programming difficulty and error probability.The welding process of whole end covers can carry out streamlined operation, improves the production efficiency of end covers greatly, and ensures that product specification is unified.
Clamping piece described in step 3) is the fixed structure on the opposite being fixed on positioner output shaft, can be simple machinery or hydraulic mechanism, also can be the automatic controls containing both.
Preferably, the gusset described in step 1) is placed in gusset Turnover Box before carrying.Gusset is placed in gusset Turnover Box, is convenient to pick and place successively, reduces the operation easier of transfer robot, is beneficial to simplification control program.
The carrying of gusset preferentially adopts can be carried out by transfer robot, and transfer robot mounting bracket can improve operation height, and the end of transfer robot is provided with the gripper jaw of clamping gusset.Transfer robot, by the gripper jaw clamping gusset of end, shifts after raising, and keeps gusset vertically to stablize in positioning welding process.
Preferably, described welding robot is gas shielded arc welding.Gas shielded arc welding can ensure welding quality.
Preferably, the angle set between the gusset described in step 1), the anglec of rotation that described positioner is each is identical.The quantity of gusset is determined according to the designing requirement of ball mill, but the angle preferably set between gusset is identical, is convenient to the automatic rotation Angle ambiguity of positioner.Also the welding of welding robot is convenient to.
Preferably, step 2) described in stiffener there is the radian identical with end covers.Stiffener and end covers design identical radian, and both paste tightr, weld more firm.
Preferably, step 2) described in the robot that circumferentially utilizes circumferentially contacted with end socket with stiffener that contacts with main shaft of stiffener carry out seal welding respectively.
Preferably, the welding robot described in step 3) is provided with two, and two welding robots carry out seal welding to the gusset of this level and relative gusset thereof respectively.In step 3) end covers opening be level towards, make robot manipulation simpler, the space taken is also less, can be implemented in main shaft both sides and respectively establishes a welding robot, two welding robots weld simultaneously, and the gusset welding efficiency of end covers doubles.
Compared with prior art, the beneficial effect that ball mill end covers welding procedure of the present invention has is: technical process of the present invention can realize the streamlined welding of ball mill end covers, first all gussets and end covers are carried out spot welding, realize calibration location, during spot welding, positioner is vertically arranged, the corresponding opening of end covers vertically upward, what be convenient to gusset ajusts placement, ensure that calibration location is easier, be convenient to realize welding and be transported through robot automatically completing, stiffener is welded between end covers and main shaft, strengthen the entirety of end covers by force intensity, main shaft can be utilized in step 3) by whole end covers horizontal positioned, now recycle welding robot and carry out seal welding, the action that completes needed for welding robot can be made simpler, be convenient to utilize simple programme-control, reduce programming difficulty and error probability.Improve the production efficiency of end covers greatly, and ensure that product specification improves the welding quality of end covers while unified greatly, improve disposable qualification rate, extend the service life of ball mill.
