In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of diesel engine starting motor brush rocker riveting set, comprise cope match-plate pattern and die shank, red needle is installed on the described cope match-plate pattern, the lower bolster that is used for location brush holder base plate is arranged on the below of described cope match-plate pattern, described cope match-plate pattern is provided with guide finger and caging bolt nut, stripper slides on described guide finger and the caging bolt nut, flexible member is sleeved on the described red needle and supports and is contained between described cope match-plate pattern and the described stripper, the red needle cover is installed on the bottom surface of described stripper, described red needle puts the major trough that is provided with spacing brush carrier body and the secondary groove of spacing brush carrier elasticity post, and described red needle is passed described stripper and described red needle cover.
Further:
Described lower bolster is slidingly mounted in the guide groove of guide rail base plate.
Described flexible member is the Polyurethane rod.
Described cope match-plate pattern is provided with spacing thimble, and described spacing thimble is arranged between described cope match-plate pattern and the described stripper.
Technique effect of the present utility model is:
The disclosed a kind of diesel engine starting motor brush rocker riveting set of the utility model, simple and compact for structure, adopt the spacing structure of red needle cover, reduce the scale error that the actuating motor brush holder produces when riveted joint, improve dimensional accuracy, improve the qualification rate of product, satisfy the high-quality requirement of reducing motor, simultaneously, lower bolster makes faster and more convenient operation along the Sliding Structures of guide rail base plate, enhances productivity, further reduce potential safety hazard, avoid taking place industrial accident.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of actuating motor brush holder riveting set in the prior art.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
As shown in Figure 1, the utility model comprises cope match-plate pattern 2 and die shank 1, die shank 1 is arranged on the end face of cope match-plate pattern 2, red needle 9 is installed on the bottom surface of cope match-plate pattern 2, the lower bolster 13 of location brush holder base plate 11 is arranged on the below of cope match-plate pattern 2, lower bolster 13 is slidingly mounted in the guide groove of guide rail base plate 15, guide groove is made of the positive stop 14 that is installed in guide rail base plate 15 both sides, when carrying out riveting operation, lower bolster 13 can be pulled out from cope match-plate pattern 2 belows, avoid when punch press is worked the operator that hand is stretched into the punch press workspace to guarantee safety, reduce the probability that industrial injury takes place, make things convenient for simultaneously the actuating motor brush holder pack into and rivet after the actuating motor brush holder take out, swift and convenient to operate, enhance productivity.Guide finger 3 and caging bolt nut 4 are installed on the cope match-plate pattern 2, and stripper 7 slides on guide finger 3 and the caging bolt nut 4, is the guiding that moves up and down of stripper 7 by guide finger 3, makes the stripper 7 can only be for vertical movement.The bottom surface of cope match-plate pattern 2 is provided with spacing thimble 5, spacing thimble 5 is arranged between cope match-plate pattern 2 and the stripper 7, flexible member 6 is sleeved on the red needle 9 and supports and is contained between cope match-plate pattern 2 and the stripper 7, flexible member 6 can adopt spring and other elastic components, in the present embodiment, flexible member 6 adopts the Polyurethane rod.Red needle cover 8 is installed on the bottom surface of stripper 7, red needle cover 8 is done vertical up-or-down movement with stripper 7, red needle cover 8 is provided with major trough 801 and secondary groove 802, major trough 801 is used for the body of spacing brush carrier 10, secondary groove 802 is used for spacing brush carrier elasticity post 1001, the body of brush carrier 10 and the distortion of elasticity post 1001 during the restriction riveted joint are offset between brush carrier 10 and the brush holder base plate 11 during restriction riveted joint simultaneously, and red needle 9 is passed stripper 7 and red needle cover 8.
When carrying out the riveted joint of diesel engine starting motor brush rocker, lower bolster 13 is pulled out from cope match-plate pattern 2 belows along the guide groove of guide rail base plate 15, brush holder base plate 11 is placed and is positioned on the lower bolster 13, and be placed on brush carrier 10 on the brush holder base plate 11 and put into rivet 12, plug 16 is inserted in the body of brush carrier 10, lower bolster 13 is pushed into cope match-plate pattern 2 belows; Start punch press, cope match-plate pattern 2 is descending, and the body of brush carrier 10 and brush carrier elasticity post 1001 enter major trough 801 and the secondary groove 802 on the red needle cover 8 respectively, by body and the brush carrier elasticity post 1001 of red needle cover 8 at first spacing brush carriers 10; Cope match-plate pattern 2 continues descending, and the Polyurethane rod of cope match-plate pattern 2 compression elastic elements 6 provides pretightning force by the Polyurethane rod, guarantees before rivet 12 expands brush carrier 10 and brush holder base plate 11 to be compressed, and avoids occurring empty riveting; Finally by red needle 9 rivet 12 is flattened and expand, brush carrier 10 and brush holder base plate 11 are riveted together; Cope match-plate pattern 2 is up, and under the elastic force effect of Polyurethane rod, stripper 7 is returned to original position, takes out the actuating motor brush holder of having riveted, the riveted joint that can enter next actuating motor brush holder.Because the common restriction of red needle cover 8 and plug 16, in the riveted joint process, limited the distortion of brush carrier 10, the elasticity post 1001 that makes the deviation of A, B size in the carbon brush chamber of brush carrier 10 and brush carrier is limited in the small range with the dimensional discrepancy of the spacing C of brush carrier body, can will control in 0.15mm with above-mentioned scale error, thereby improved the precision of brush holder significant dimensions A, B, C greatly, efficient and the life-span of significantly improving the high-power diesel actuating motor, saved the wealth of society.
