No adhesive is used, so the utility model is environment-friendly and does not have any adhesive trace, and the opening and the inner wall of the shell do not need to be cleaned. According to the utility model, the steel magnets can be assembled conveniently, quickly and efficiently, and the time for the whole steel magnet fastening process is less than 20 seconds; the steel magnets can be immediately magnetized and put into the production line without crushing the steel magnets; and the steel magnets can be taken out for reuse.
Description
Technical field
The utility model belongs to technical field of motors, specifically, and the particularly fixed structure of starter motor magnet steel.
Background technology
The magnet steel of starter motor is fixed on the casing for a long time, all adopts powerful bonding agent (AB glue) bonding.Its technical process roughly is; Apply A glue earlier at the magnet steel back side; On casing inner wall, apply B glue, the position of confirming according to positioning tool pastes casing inner wall to magnet steel, makes magnet steel be close to casing with the tensioner frock again; Wait for and just magnetizing after the bonding agent full solidification more than 12 hours, go up streamline then and carry out the motor assembling.Its major defect is following:
1, use the powerful bonding agent of chemical synthesis, it is pungent that the smell is awful, and not environmental protection influences workers ' health.
2, the production cycle long, need bonding agent curing time more than 12 hours, can not magnetize at once and go up streamline.
3, in magnet steel tensioner process, magnet steel is broken easily.
4, be adhesively fixed after magnet steel be not easy to take out, take out must broken magnet steel, and removes the glue trace difficulty very in the casing.
5, during adhesive-applying, accidentally will be coated onto on the casing seam, influence assembly quality, cause poorly sealed and leak, must check at any time and remove the glue trace.
6, need the bonding magnet steel of 2 people just can catch up with pipelining, also need 1 people to press-fit oiliness bearing, cost of labor is high.
The utility model content
The utility model technical problem to be solved is to provide a kind of installation magnet steel starter motor magnet steel fixed structure easily.
The technical scheme of the utility model is following: a kind of starter motor magnet steel fixed structure; Comprise motor case (1) and magnet steel (2); Magnet steel (2) is a circular arc, and its key is: in said motor case (1), be provided with support (3), this support (3) and motor case (1) interference fit; On said support (3), be symmetrically installed with two blocks of magnet steel (2), the inwall of the exterior arc surface of magnet steel (2) and motor case (1) fits tightly.
The utility model is set up a fixedly support of magnet steel; Earlier magnet steel is installed on the support during assembling, with the mode of positioning tool support is pressed in the motor case together with magnet steel again, can realize the assembling of magnet steel with interference fit; Not only simple to operate, quick; It is firm that magnet steel and support are installed, and need not after being pressed into to wait for the entering assembling line that can magnetize, and shortened the production cycle greatly.The utility model does not re-use bonding agent, and environmentally-friendly sanitary can not influence the healthy of operator.
Said support (3) is through injection mo(u)lding; Form by locating ring (3a) and card base (3b); The inwall of the outer circumference surface of locating ring (3a) and motor case (1) is fitted; Be symmetrical set two card bases (3b) in the below of locating ring (3a), two blocks of magnet steel (2) are installed between two card bases (3b).Above structure support processing and fabricating on the one hand is easy, and materials are few in light weight, and cost is roughly suitable with the employing bonding agent; On the other hand, magnet steel is installed on the support very convenient.
The inwall inwardly protruding on said motor case (1) top forms two symmetrically arranged wedge shape boss (1a), and said wedge shape boss (1a) is up big and down small, and the bottom surface of said locating ring (3a) is spacing by wedge shape boss (1a).Above structure can limit bracket axial displacement, also can limit its radial displacement, has further guaranteed the fixing of assembling.
Said card base (3b) is a circular arc, and two card bases (3b) and two magnet steel (2) are formed a complete annulus, and the size of this annulus equates with locating ring (3a).Above structure can avoid magnet steel to take place circumferentially to move relative to support, makes the magnet steel location good.
All be formed with blend stop (3c) in the both sides of said card base (3b); This blend stop (3c) is " L " shape; The long limit of blend stop (3c) is formed along the circumferencial direction extension by the exterior arc surface of card base (3b); The minor face of blend stop (3c) is formed along the circumferencial direction extension by the bottom surface of card base (3b), and said magnet steel (2) is spacing by blend stop (3c).Above structure can be guaranteed the not axial and radial displacement of support generation relatively of magnet steel, has further improved the fixing that magnet steel is located on support.
The effect of having a mind to of the utility model is:
1, without bonding agent, environmental protection.
2, the production cycle very short, the fastening magnet steel overall process time can be magnetized immediately and go up streamline in 20 second.
3, can wholely take out magnet steel with take-off device, magnet steel can fragmentation not have the glue trace yet, and magnet steel can also re-use.
4, adhesive-free glue trace need not cleaning with inwall on the casing mouth.
5, support adopts plastic material, and very light consumption is also few, and cost is low.
6, adopt a pair to be pressed into positioning tool, only need 1 people just can accomplish simultaneously and press-fit magnet steel and oiliness bearing, improved work efficiency greatly.
