Description
Technical field
The present invention relates to compressor opening cover dismounting device and method.
Background technology
In increasing waste household appliances, refrigerator and air-conditioner have accounted for very big proportion, and compressor is the core component of refrigerator and air-conditioner, no matter are maintenance or recovery, need that all it is opened shell and handle.
The compressor case of refrigerator and air-conditioner is generally the Q235 steel plate, and thickness is between 3～4mm.Wherein cooler compressor mostly is cylindrical, and the compressor for refrigeration shape is complicated, and cross sectional shape mainly contains the rectangle of circle, ellipse and band fillet etc.
Domestic and international method for opening shell of the prior art comprises:
1, cryogenic pulverization: adopt cooled with liquid nitrogen, cryogenic pulverization.But equipment operating cost height, energy consumption height, big, the serious wear of noise can't utilize after shell is broken, and the part of cryogenic conditions lower compression machine inside can be damaged again in the shattering process.
2, portable saw cutting: can only be at the maintenance or the recovery of small lot, the equipment cheap and simple, but kerf quality is poor, and labour intensity is big, and efficient is low, is not suitable for producing in batches.
3, plasma cutting: otch is narrow, quality of cut face good, and cutting speed is fast.But because of the shell of compressor is not smooth steel plate, but revolving body is difficult to guarantee cutting torch and the constant distance of case surface in the cutting process, if cutting torch is run into shell, then can burn out electrode; The air-flow of cutting process high speed can blow to the molten metal slag particle inside of compressor, brings inconvenience to subsequent recovery.
4, flame cutting: utilize gases such as acetylene or propane and oxygen mix burning to carry out flame cutting, cost is low, and cutting speed is fast.But because the injection of oxygen jet, Mars, bead and scum splash everywhere, cause the accident of scalding of burning easily; The molten metal of quilt evaporates under high temperature action, condensation becomes metal fumes, insalubrity behind the suction human body; Flame and molten metal drop can impact inner body.
5, grinding wheel cutting: equipment cost is low, the cutting efficiency height; But noise is big, and dust is big, and abrasion of grinding wheel is fast, easily broken, dangerous.
6, lathe turning:, can adopt general horizontal lathe to cut shell for columniform cooler compressor.This method is to utilize universal machine tools, does not need special equipment, but can only handle columniform compressor, and is powerless for the compressor of noncircular cross section.
7, profile milling: Chinese invention patent CN1927478A, a kind of casing opening and disassembly device of waste and old compressor is provided, what this equipment adopted is the profile milling method.But compressor case is formed by punching of the steel plate, and appearance has a pattern draft, in milling process, can't guarantee that the profiling pinch roller closely contacts with compressor case, produces vibration in the time of will causing milling like this, and kerf quality is poor, and cutter is fragile.This equipment is fully by manual operations, and it is low to open shell efficient.
Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology weak point, a kind of compressor opening cover dismounting device and method being provided.Make on the one hand the opening the shell operation safe, reliably, do not damage the compressor inner body of compressor, reusability is good, otch is little and smooth, repair after welding easily; Make the shell of opening of compressor operate efficient more, energy-saving and environmental protection on the other hand.
Technical solution problem of the present invention adopts following technical scheme:
The design feature of compressor opening cover dismounting device of the present invention is:
Compressor is the end face that vertically is fixedly installed on workbench; The workbench layering is provided with, and its upper strata is the revolution layer by upper strata servomotor control rotation; Lower floor is by the translation layer of lower floor's servomotor control along the horizontal guide rail move left and right;
Linear displacement transducer is set, and the horizontal measuring staff of linear displacement transducer is in opening on the shell height of compressor, and horizontal measuring staff is along the translation direction setting of table translation layer, and the centre of gyration line of the center line of horizontal measuring staff and work table rotation layer intersects vertically; The detecting head of horizontal measuring staff is resisted against on the compressor opening cover position with elastic pressure;
Being the relative compressor opening cover position opposite side of 180 degree, cutterhead is set is the milling cutter that level is installed with detecting head; The central point of cutterhead drops on the center extended line of horizontal measuring staff.
The characteristics of compressor opening cover dismounting method of the present invention are to measure and remembered the shape of compressor case before opening shell in advance with linear displacement transducer, control cutting tool then and rotate a circle with respect to compressor case according to memorized shape, finish cutting and open shell.
Compressor opening cover dismounting method characteristics of the present invention are to operate as follows:
A, control upper strata servomotor make the compressor revolution that is placed on the bench top, keep centre of gyration invariant position; Detecting head with linear displacement transducer is resisted against opening on the shell position of compressor simultaneously; Least radius place with compressor is an original position, obtains compressor complete cycle boundary position information by linear displacement transducer;
B, according to the compressor complete cycle boundary position information that is obtained, control upper strata servomotor and lower floor's servomotor respectively, along the straight-line displacement of horizontal measuring staff direction, keep constant milling cutter in cutterhead center and compressor case tangent with the revolution of compressor and the compressor centre of gyration by the degree of depth of setting.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, apparatus of the present invention make the opening the shell operation safe, reliably, do not damage the compressor inner body of compressor, reusability is good, otch is little and smooth, repair after welding easily.
2, the inventive method makes the shell of opening of compressor operate efficient more, energy-saving and environmental protection.
