The device comprises a No.20 steel tube, stainless steel bolts and neodymium iron boron material; an aluminum depression bar is put into a V-shaped cavity body of the neodymium iron boron material; the center of the V-shaped cavity body of the neodymium iron boron material aligns at a fixing hole of the No.20 steel tube; the aluminum depression bar, the neodymium iron boron material and the No.20 steel tube are fixed through the stainless steel bolts; a guide edge is formed on the V-shaped cap of the stainless steel bolt; dynamic locking positioning is formed between the position of the guide edge and the aluminum depression bar; the V-shaped cavity body is a cavity when not being locked; and a locking device produces a downward acting force adjacent to the top end surface of the aluminum depression bar through stress application, so as to ensure that the aluminum depression bar forms a local directional outer edge, and a cavity is formed between a position where the aluminum depression bar enters to the guide edge and the aluminum depression bar to form dynamic locking positioning.
Description
Technical field
The utility model relates to a kind of motor, relates to a kind of specific type of electric machine exactly, is specifically related to the magnet steel fixture of a kind of forging machine tool with rotor.
Background technology
At present, the specific type of electric machine rotor adopt " neodymium iron boron " material, " neodymium iron boron " be a kind of magnetic force very by force, frangible material again; 96～120 magnet steel that every suit rotor is processed with this material, each magnet steel is of a size of (LxWxB) 80x40x8, is fixed with aluminium layering; Aluminium layering is fixed with stainless steel screw, and in forging machine tool high-frequency rotary course, screw produces loosening press strip and the magnet steel of causing and becomes flexible; Thereby cause magnet steel to break, burn-down of electric motor.
Summary of the invention
The purpose of the utility model provides the magnet steel fixture of a kind of forging machine tool with rotor; Exist aluminium layering to cause magnet steel to break easily with the rotor that solves employed motor in the present forging machine tool, the problem of burn-down of electric motor takes place because of shaking to get loose easily.
The purpose of the utility model is to realize like this; A kind of forging machine tool is with the magnet steel fixture of rotor; It is characterized in that: comprising: No. 20 steel pipes, stainless steel screw and " neodymium iron boron " materials; Aluminium layering is put into the v-shaped cavity body of " neodymium iron boron " material, No. 20 steel pipe fixing holes of v-shaped cavity body centrally aligned of " neodymium iron boron " material are fixed an aluminium layering, " neodymium iron boron " material and No. 20 steel pipes with stainless steel screw; " V " type of stainless steel screw emits guide margin is arranged, and forms dynamic locking bit between the position of guide margin and the aluminium layering.
Two or front, rear, left and right were four about said guide margin had at least.
There is aluminium layering to embed the chamber between said aluminium layering and " neodymium iron boron " material; When the fixing hole of stainless steel screw process aluminium layering connected as one No. 20 steel pipes, " neodymium iron boron " material and aluminium layerings, aluminium layering embeds the chamber made stainless steel screw and " neodymium iron boron " material form the air gap.
The dynamic locking bit size that described guide margin and aluminium layering form is between 2～3 millimeters.
The advantage of the utility model: form dynamically locking owing between stainless steel screw and aluminium layering, have; Like this when motor is given a shock; Screw can not become flexible, and has overcome in the motor operation course screw loosening and cause aluminium layering to get loose causing magnet steel by shatter problem.The utility model just to the shape of screw head and with aluminium layering between cooperate and improve, realize very simple.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Fig. 1 is that screw cooperates the front schematic view that compresses magnet steel with aluminium layering;
Fig. 2 is the part sectioned view of Fig. 1.
Among the figure: 1, stainless steel screw; 2, dynamic locking bit; 3, aluminium layering; 4, " neodymium iron boron " material; 5, No. 20 steel pipes; 6, aluminium layering embeds the chamber; 7, locking instrument; 8, guide margin.
Embodiment
Fig. 1, shown in Figure 2ly be the magnet steel fixed pan sketch map in the rotor that the utility model provided; Fig. 2 is the part sectioned view of Fig. 1, and the specific type of electric machine rotor is fixing many circle " neodymium iron boron " materials 4 on No. 20 steel pipes 5, " neodymium iron boron " material 4 be a kind of magnetic force very by force, frangible material again; 96～120 magnet steel that every suit rotor is processed with this material; Each magnet steel is of a size of (LxWxB) 80x40x8, compresses with aluminium layering 3, with the fixing hole of stainless steel screw 1 through aluminium layering 3 No. 20 steel pipes 5, " neodymium iron boron " materials 4 is connected as one with aluminium layering 3 then; " V " type of stainless steel screw 1 emits guide margin 8 is arranged; Two or front, rear, left and right were four about guide margin 8 had at least, formed dynamic locking bit 2 between the position of guide margin 8 and the aluminium layering 3, had not been cavity before the locking; Through reinforcing locking instrument 7 is acted on downwards at the top end face near the aluminium layering 3 of guide margin 8; Make aluminium layering 3 form local direction property outer, form cavity between the position of the local outer entering guide margin 8 of aluminium layering 3 and the aluminium layering 3 and form dynamic locking bit 2, after " V " of a stainless steel screw 1 type emits guide margin 8 corresponding dynamic locking bits 2 to accomplish; Accomplish other dynamic locking bit 2 successively, up to all stainless steel screw 1 peripheries and the dynamically locking of aluminium layering 3 formation of fixing 96～120 magnet steel.Form dynamically locking owing between stainless steel screw 1 and aluminium layering 3, have, when motor was given a shock, screw can not become flexible like this, had overcome in the motor operation course screw loosening and cause aluminium layering to get loose causing magnet steel by shatter problem.
In addition; There is aluminium layering to embed chamber 6 between aluminium layering 3 and " neodymium iron boron " material 4; When the fixing hole of stainless steel screw 1 process aluminium layering 3 connects as one No. 20 steel pipes 5, " neodymium iron boron " material 4 and aluminium layerings 3; Aluminium layering embeds chamber 6 and makes stainless steel screw 1 and " neodymium iron boron " material 4 formation air gaps, can cushion stainless steel screw 1 and neodymium iron boron " material 4 the two direct effect when vibrations, reach the protection neodymium iron boron " purpose of material 4.
During installation: the v-shaped cavity body of aluminium layering 3 being put into " neodymium iron boron " material 4; No. 20 steel pipe 5 fixing holes of the v-shaped cavity body centrally aligned of " neodymium iron boron " material 4; With stainless steel screw 1 aluminium layering 3, " neodymium iron boron " material 4 and No. 20 steel pipes 5 are fixed, because of repelling each other between " neodymium iron boron " material (magnet steel) and " neodymium iron boron " material (magnet steel), after having adorned first; When refilling second block of magnet steel; To two blocks of magnet steel be forced to connect with special fixing device, then near the screw the magnet steel press strip tightened, by that analogy assembling.After having adorned etc. whole magnet steel, with the stainless steel specific purpose tool all with screw.At this moment, along the locking of head of screw long axis direction, let aluminium layering 3 produce distortion with locking instrument 7, material flow to guide margin 8, and screw can not be rotated.Thereby guarantee motor when high speed rotating, screw can not become flexible, and magnet steel is also just guaranteed motor safety property not by shatter, and Electric Machine Control is normal.
