Description
Technical field
The present invention relates to a kind of compressor of combined threaded rod, particularly relate to toothed sheet parts that a kind of employing quenched by multi-disc be inserted in axle after after gluing superposition and spot welding form the compressor of the combined threaded rod of screw rod axis body.
Background technique
Helical-lobe compressor, also screw compressor is claimed, comprise screw air compressor and screw rod technique compressor (vinyl chloride compressor etc.), helical-lobe compressor is divided into single screw compressor and double-screw compressor, and helical-lobe compressor utilizes screw axis shape rotor to compress and fed sheet of a media do rotation motion in cylinder body.
It is high that helical-lobe compressor has reliability, and component are few, do not have easily damaged parts, and thus its running is reliable, and the life-span is long, and general screw machine host header reaches 30 years projected life; Convenient operating maintenance, automaticity is high, and operator, without the need to through long-time professional training, realize unmanned running; Dynamical balancing is good, does not have unbalance inertia force, and machine can high speed operation reposefully, realizes foundation-free running; Strong adaptability, has the advantages that to force gas transmission, and volume flow is hardly by the impact of exhaust pressure, higher efficiency can be kept in the condition range of broadness, when compressor arrangement without any changes, be applicable to various working, thus be easy to sizing batch production; Multi-phase mixed delivering, in fact leaves gap between the rotor flank of tooth, thus ability hydraulic shock, can force feed containing the gas of liquid, containing dusty gas, easy polymerizable gas etc.; Guiding valve Flow-rate adjustment, do not need to return stream, can effectively reduce the advantages such as energy consumption, therefore, helical-lobe compressor is widely used.
The subject matter that current containment helical-lobe compressor develops is that the cost of helical-lobe compressor is high, the flank of tooth due to the screw axis rotor of screw machine is a space curved surface, the outer contour in its cross section is formed by connecting by the curve of multiple complexity, the curved surface of the flank of tooth of overall screw axis rotor is formed through spiral stretch by the external frame of above-mentioned complex curve, the flank of tooth of screw axis rotor is the curved surface of a complicated stereoscopic three-dimensional, therefore, turning common in machining and milling device not competent, numerical control turning general at present and milling device can not be processed, need to utilize special cutter to process on expensive special device in machining.
The processing of screw axis rotor, divides from product material, is generally divided into foundry goods cutting and forged steel pieces cutting.
The screw axis rotor that foundry goods cutting is shaped, necessary first cast form, then with machining center and dedicated tool cutting, the screw axis rotor that the quality such as rigid, wear resistance of product is cut relative to forged steel pieces is weaker.
During the screw axis rotor machining that forged steel pieces cuts, must first by steel formed by forging, then with machining center and dedicated tool repeatedly cutting, Quenching Treatment and surface finishing is carried out again after shaping, therefore, technological requirement is high, technological process is complicated, processing speed is slow, cost of production is high.
In actual production, production enterprise often adopts import machining center and import cutter to complete processing, and enterprise is when purchasing high-end import machining center, and be subject to the technology restriction of developed country, meanwhile, import equipment and import cutter substantially increase cost of production.
This case work in-process have employed spot-welding technology, described spot-welding technology utilizes electric welding machine to realize, the principle that spot welding machine system adopts two-sided two point overcurrent to weld, during work, two electrode pressurization workpiece make double layer of metal form certain contact resistance under the pressure of two electrodes, and welding current from an electrode stream through another electrode time two contact resistance points formed moment thermal fusion weldings, and welding current moment flow to this electrode formation loop from another electrode along two workpiece, do not injure the internal structure of welded piece, spot welding machine divides according to purposes, there is universal (general-purpose type), specialized type, divide according to the solder joint number welded simultaneously, have single-point type, kinds of point mode, multipoint mode, divide according to electrically conducting manner, have one-sided, bilateral, divide according to the kind of drive of pressurizing mechanism, have foot-operated, motor-cammingly, pneumatic-typed, hydraulic type, combined type (Gas fluid pressure is box-like), divide according to the characteristic of running, have non-automated, automation, divide according to the method for installing, have fixed, portable or portable (suspension type), divide according to the movement direction of the float electrode (common is upper electrode) of welding machine, have vertical stroke (electrode moving linearly), circular arc stroke, divide according to the supply mode of electric energy, have power frequency welding machine (adopting 50 hz AC power supplys), pulsating welder (DC pulse welding machine, percussion welder etc.), frequency conversion welding machine (as low frequency welder).
Summary of the invention
The technical problem that the present invention solves is: in order to solve, prior art compressor complex process, long processing time, difficulty of processing when processing screw axis are large, processing cost high-technology defect, a kind of compressor of screw axis is provided, particularly relate to a kind of toothed sheet parts quenched by multi-disc be inserted in axle after after gluing superposition and spot welding forms the compressor of the combined threaded rod axle of screw rod axis body, reach the technical purpose of low cost, the fast high physical property compressor of manufacture.
The technological scheme of technical solution problem of the present invention is:
In order to reach technical purpose of the present invention, the compressor of a kind of combined threaded rod provided by the invention, comprise cylinder, screw axis is had in cylinder, described screw axis is a kind of sheet parts combined threaded rod axle, screw axis also comprises sheet parts, axle, there are engaging piece at the bottom of tooth and tooth top engaging piece in the outside of sheet parts, axis hole is had in sheet parts, a profile of tooth is had at least to protrude in axis hole, the outside of axle has a spiral groove at least, the quantity that profile of tooth in sheet parts axis hole is protruded is identical with the quantity of the groove of the external helicoid shape of axle, and cooperatively interact, the cover that the outside of axle is closely orderly has multi-disc sheet parts, relative position between axle and multi-disc sheet parts is fixed, the glue of solidification is filled with in gap mutual between axle and multi-disc sheet parts, the process step of screw axis is as follows:
