Description
Technical field
The utility model relates to a kind of boring device, especially drum boring device.
Background technology
Station boiler, Industrial Boiler generally have drum, drum need connect many pipes, and the connection of these pipes generally has welding and expanded joint two kinds of methods.No matter adopt which kind of method to connect, all need to open open-work on drum.These bore dias are generally tens millimeters, and the quantity in hole is many, and density is large, and the position accuracy demand in hole is high.The technical process current drum being opened open-work is: adopting manual type to rule to drum, needing the position of perforate to mark cross centre line, drawing the circle needing perforate with compasses, and stamps ocean punching in the position that circumference is crossing with cross centre line; Then the orientation direction hole of drilling machine subdrilling minor diameter, Shi center Yang Chong position, then reaming drilling is carried out with drilling machine on the basis in orientation direction hole, reach the aperture of drawing requirement.
There is following shortcoming in existing technique:
1, artificial line is higher to the technical requirement of personnel, easily goes wrong.At hundreds of to several thousand not etc., a large amount of line workloads is a test to operating personnel's patience for the drilling hole amount of general drum.If bore position goes wrong, material impact will be produced to boiler quality, and even may need to scrap drum, form huge economic loss.
2, operating efficiency is low.After line completes, special reviewer is needed to check line situation, to determine that position of opening meets drawing requirement.Then position the drilling of bullport, then carry out reaming.Need repeatedly to operate at same position.
3, error is large.The precision of artificial line has larger associating with the technical merit of operating personnel, and manual operations is to the confirmation of position completely with sensation, and the collimation error can reach 0.5mm.Add the error of the diameter of upper drum own.These errors have an impact to the location of pore.
4, main equipment is needed to process.Because drum diameter is large, length is long, the weight of general drum is single-piece the heaviest in boiler component.Need to carry out rotation displacement to drum in line and boring procedure, need larger equipment to realize.
Along with the progress of technology, Digit Control Machine Tool progressively obtains application, in drum manufacture process, also there is several multi-form numerical control drilling machine, main working mechanism is: the circumference location achieving drum with the fixture of calibration, achieve axial location with guide rail, location of computerizeing control instead of artificial line, achieves the boring of intelligentized drum.Compare with complete manual operations, precision and operating efficiency all have raising in various degree, for boiler manfacturing automation provides condition.But because bit cutting active force is large, Digit Control Machine Tool is also grasped exists following shortcomings:
1, indexing fixture is huge.Drum weight and length are all comparatively large, and Numeric Control Technology needs to carry out indexing operation and control to drum flexibly, needs huge machinery could realize the flexible rotating of drum.
2, drilling elaboration power is large.Drilling processing needs drilling machinery to have certain power to realize drilling operation to workpiece, so only can not flexibly and rotate displacement accurately when calibration to the requirement of indexing fixture, need again in drilling process after completing displacement to keep stable by enough rigidity, this just more needs indexing fixture comparatively huge.
3, cut work efficiency to need to be improved further.Boring work efficiency is determined by drill unit, and drilling efficiency is strictly said the raising not having matter with manual operations.The effective measures taked at present are the quantity increasing unit head, and a number of units controlled machine configures the cutting power head of a greater number.
4, directly spectacle groove cannot be processed.Drilling processing directly cannot process spectacle groove, if need to carry out groove process to boring, needs more bit change.
5, big circle cutting cannot realize.The power limit of the cutting power head opening diameter of machine.The hole exceeding certain diameter cannot provide Digit Control Machine Tool to realize perforate.
Utility model content
The purpose of this utility model be exactly in order to overcome above-mentioned prior art exist defect and the drum boring device that a kind of working (machining) efficiency is high, perforate precision is high is provided.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of drum boring device, comprising:
For supporting or rotate the drum turning rolls of drum,
For determining the robot of drum position of opening,
Be connected with robot and robot slide unit with mobile robot movement,
Be connected with robot head end, to the high-pressure water knife unit of drum perforate,
And, the controller of respectively control slide unit, robot and the action of high-pressure water knife unit.
Described robot slide unit is arranged in the left part of drum, right part or top, and described robot is slidably connected at top or the bottom of robot slide unit.
Described drum turning rolls is electric roller frame.
Described high-pressure water knife unit is water-jet cutting machine, and the water jet cutting head of this water-jet cutting machine is fixed on the front end of robot.
Described controller is electrically connected with robot and high-pressure water knife unit simultaneously, and described controller is programmable logic controller (PLC).
Compared with prior art, the utility model has the following advantages and beneficial effect:
1, owing to adopting high-pressure water knife cutting, device stressed very little, greatly can reduce rigidity and the size of device, realize economical and effective cutting processing.
2, position of opening precision is high.Because the control of robot can gather the out-of-roundness of drum and the nonstraightness of cylindrical shell in advance, can locating holes position accurately, avoid because cylindrical shell out-of-roundness and nonstraightness cause error to position of opening.
3, opening diameter is unrestricted.Owing to being direct cutting, device cuts according to the saddle-shaped curve calculated, and not by the restriction such as tool diameter, machine power, can output the hole of any size in theory, and can one-shot forming, do not need to change cutter.
4, linear groove at any angle can be processed.According to split requirement, need the cylindrical shell of cutting straight line shape groove, can one-shot forming.
5, owing to being cold working, do not have heating process, barrel distortion is little; Without thermal stress.
