[detailed description of the invention]
Below in conjunction with accompanying drawing, the present invention is further detailed explanation.
As shown in Figure 1 and Figure 2, a kind of line pressure shift dual control pressing machine, for press-fiting of ball pin seat 21 and knurled nut 22, it comprises board 11, base 12, carrier 13, body 14, first cylinder 15a and press-fits drift 15, base 12 is fixed on board 11, and carrier 13 is installed on base 12 upper surface, and body 14 is located at above base 12, first cylinder 15a is installed on above body 14, press-fits drift 15 and drives by the first cylinder 15a and pass body 11; Press-fit drift 15 and be provided with pressure inductor 151, base 12 side is provided with travel switch 16a, press-fits drift 15 side and is provided with collision block 16b for contacting travel switch 16a.Carrier 13 is provided with for the stopper slot 131 of place kick key seat 21 and the some vertical perforation 133 for dodging knurled nut 132.When ball pin seat 21 is placed in stopper slot 131, and knurled nut 132 is when being placed in the hole of ball pin seat 21, press-fit drift 15 and press down, the collision block 16b of side can be thereupon descending, touching travel switch 16a when press-fiting collision block 16b when drift 15 moves to minimum point, now press-fiting drift 15 action and stopping.The resistance that between ball pin seat 21 and knurled nut 22, interference fit produces can be sensed by pressure inductor 151; if resistance is less than standard value; illustrate knurled nut 13 relatively too little the or knurled nut 13 in ball pin seat 21 hole do not lay in place; processing mistake; can shut down at once or report to the police, avoid and not mate with ball pin seat press mounting hole due to knurled nut and the installation produced is bad.
With reference to Fig. 1, be provided with slide plate 152 below pressure inductor 151, slide plate 152 level is located at and is press-fited drift 15 bottom, slide plate 152 is uprightly fixed with two limited posts 153, and limited post 153 activity is through body 14.Limited post 153 can only move at vertical direction by guid skateboard 152, and restriction press-fits the direction of drift 15 then, prevents its unstability, and slide plate 152 can abutment pressure inductor 151 simultaneously.
With reference to Fig. 1, Fig. 2, carrier 13 side is provided with the second cylinder 13a for driving its level to retreat, and is provided with the first guide rail 121 for limiting carrier 13 glide direction above base 12.Be provided with the 3rd cylinder 17a below base 12, the 3rd cylinder 17 drives spacing mandril 17a, and spacing mandril 17a penetrates in vertical perforation 132.Because ball pin seat 21 has multiple press mounting hole, different press mounting holes can be delivered to and press-fit below drift 15 by moveable carrier 13, can prevent carrier 13 and ball pin seat 21 from moving in the horizontal direction when spacing mandril 17a inserts vertical perforation 132 again.
With reference to Fig. 3, carrier 13 both sides are provided with photoelectric sensor switch (light emitting source 133a, light-receiving device 133b), be provided with the some horizontal perforation 133 sending light beam for transmission photoelectric sensor switch light emitting source 133a in carrier 13, each horizontal perforation 133 is through a vertical perforation 132.When knurled nut 22 is inserted ball pin seat 21 installing hole and is penetrated the vertical perforation 132 of carrier 13, knurled nut 22 can block the light beam that light emitting source 133a sends, light-receiving device 133b does not detect that light beam can judge to be inserted with knurled nut 22 in corresponding vertically perforation 132, can confirm the stage belonging to current processing.
With reference to Fig. 1, Fig. 2, board 11 is also provided with feed mechanism, and feed mechanism comprises the vibrating disk 181, delivery device 182 and the pinch mechanism 183 that set gradually; Delivery device 182 comprise along movement of retreating perpendicular to vibrating disk 181 Way out tool 1821, for driving the four-cylinder 1821a of tool 1821 and limiting the second guide rail 1822 of tool 1821 moving direction, tool 1821 is provided with the groove only holding a knurled nut 22; Pinch mechanism 183 comprises the 3rd guide rail 1831 that level fixes, the 5th cylinder 1832 of movement on the 3rd guide rail 1831, the 6th cylinder 1833 driving the 5th cylinder 1832 to move horizontally and drives by the 5th cylinder 1832 and jaw 1834 for clamping knurled nut 22, jaw 1834 above tool 1821 release location and above carrier 13 between move.Vibrating disk 181, delivery device 182 and pinch mechanism 183 carry out respectively knurled nut 22 arrangement, be separated and lay in place, achieve the self-feeding of knurled nut 22.
During use, ball pin seat 21 is first fixed in the stopper slot 131 of carrier 13, now spacing mandril 17 penetrate carrier 13 vertical perforation 132 in and through an anon-normal of ball pin seat 21 to the press mounting hole press-fited below drift 15, make carrier 13 move horizontally; Knurled nut 22 arranges and sends from afterbody by vibrating disk 181, knurled nut 22 bottom enters into the groove of tool 1821, top is exposed to above tool 1821, tool 1821 is released by the 3rd cylinder 1821a, single knurled nut 22 is made to be chosen, then knurled nut 22 is moved to above carrier 13 by jaw 1834 gripping, knurled nut 22 is placed in ball pin seat 21 just in the press mounting hole press-fited below drift 15, then tool 1821 and jaw 1834 return initial position with next knurled nut 22 to be conveyed; Jaw 1834 leaves above carrier 13 and after photoelectric sensor switch detects the knurled nut 22 inserted in vertical perforation 132, press-fit drift 15 and press down, first knurled nut 22 be pressed in first press mounting hole of ball pin seat 21; If travel switch 16a and pressure inductor 151 detect that then press-fit drift 15 and return, spacing mandril 17 exits carrier 13 without press-fiting problem; Then the second cylinder 13a drives carrier 13 to move, and another press mounting hole on ball pin seat 21 is moved to and press-fits below drift 15, and now another knurled nut 22 is placed in this press mounting hole and carries out next step and press-fit by jaw 1834; End-use device gets back to original state, and press-fiting complete ball pin seat 21 can by taking out by hand with knurled nut 22 entirety.
Above-described is only some embodiments of the present invention.For the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
