The specific embodiment
Refer to Fig. 1 to Figure 17, the present inventor is in order to understand technical scheme of the present invention better, below by embodiment particularly, and is described in detail by reference to the accompanying drawings:
A kind of trunnion shaft hot pressing assembling device of the present invention, for trunnion shaft body and sprocket wheel are assembled by hot pressing, hot pressing is assembled into trunnion shaft.
Refer to Fig. 1 to Fig. 6, the trunnion shaft using on automobile, comprises trunnion shaft body 91, sleeve 92, pad 93 and sprocket wheel 94.Wherein, trunnion shaft body 91 comprises axle bottom 911, axle middle part 912 and axle top 913.The cross sectional shape at its axis middle part 912 is semicircle, because the cross sectional shape at axle middle part 912 is semicircle, therefore the outer peripheral face at axle middle part 912 is to be surrounded by a curved surface and a plane, and the two ends up and down of wherein said plane are respectively equipped with two upper anchor points 95 and two lower anchor points 96.
Sleeve 92 comprises that one for the sleeve joint hole 921 of axle top 913 sockets with trunnion shaft body 91.The top of sleeve 92 is provided with a sleeve edge 922, and sleeve edge 922 is provided with a positioning through hole 923.The radial center of sprocket wheel 94 is provided with one for the sprocket wheel sleeve joint hole 941 of axle top 913 sockets with trunnion shaft body 91.
On the outer peripheral face at the axle top 913 that sleeve 92, pad 93 and sprocket wheel 94 are socketed from bottom to up successively.
Trunnion shaft is divided into air inlet lateral balance axle and exhaust side trunnion shaft.The axle bottom 911 of the trunnion shaft body 91 of air inlet lateral balance axle and exhaust side trunnion shaft, axle middle part 912 and axle top 913, and sleeve 92 there are differences on section shape and size.
The another one difference of air inlet lateral balance axle and exhaust side trunnion shaft is the difference of the play interstitial site that a height is h.In air inlet lateral balance axle, the position in play gap is between the bottom surface of pad 93 and the end face of sleeve 92.And in exhaust side trunnion shaft the position in play gap between the bottom surface of sleeve 92 and the end face at axle middle part 912.
On the end face of sprocket wheel 94, print and have a sprocket wheel gauge point 942 simultaneously, the end face at axle top 913, the end face of trunnion shaft body 91 is printed a trunnion shaft gauge point 914.Take the center of trunnion shaft body 91 end faces is summit, the projection on horizontal plane with the center of trunnion shaft body 91 end faces and the line of sprocket wheel gauge point 941, and the center of trunnion shaft body 91 end faces and the line of trunnion shaft gauge point 914 be projected as both sides shape in an angle on horizontal plane, this angle is the setting angle θ of trunnion shaft.
Consult Fig. 7, a kind of trunnion shaft hot pressing assembling device of the present invention, comprises a trunnion shaft transmitting device 100, sprocket wheel transmission line 200 and hot press 300.
Refer to Fig. 8 to Figure 11, trunnion shaft transmitting device 100 wherein, comprises an index table assembly 101 that can horizontally rotate, on the end face of index table assembly 101, around eight the trunnion shaft fixtures 500 that are evenly distributed in of index table assembly 101 end faces.Eight trunnion shaft fixtures 500 are corresponding to eight stations of index table assembly 101, the first station to the eight stations that set gradually in the counterclockwise direction.
Refer to Figure 12 to Figure 14, trunnion shaft fixture 500 comprises, clamp bottom board 51, lower positioning seat 52, upper positioning seat 53.Fixture angle fixation kit 54, sleeve locating shaft 55, angle type handle 56 and handle keyset 57.
Wherein clamp bottom board 51 is connected on the end face of index table assembly 101, and lower positioning seat 52 is fixed on the end face of clamp bottom board 51, in order to balance support shaft balancing axle body 91.Upper positioning seat 53 is fixed on the end face of lower positioning seat 52.Upper positioning seat 53 is provided with the location mistake proofing through hole 531 of a vertical direction, and the shape of the shape of inwall of location mistake proofing through hole 531 and the axle of trunnion shaft body 91 bottom 91 outer peripheral faces matches.Therefore, only have the shape of axle bottom 911 outer peripheral faces could insert location mistake proofing through hole 531 with the trunnion shaft body 91 that location mistake proofing through hole 531 inner wall shape match, and forming circumference with the inwall of location mistake proofing through hole 531 contacts, that is to say that axle bottom 911 can insert in location mistake proofing through hole 531, the outer peripheral face of axle bottom 911, and there is not gap between the inwall of location mistake proofing through hole 531.If it is incorrect that trunnion shaft body 91 is installed, trunnion shaft body 91 cannot be installed.Can prevent from like this misplacing in trunnion shaft fixture 500 trunnion shaft body 91, thereby cause the loading error of trunnion shaft.
Fixture angle fixation kit 54 is positioned on the end face of positioning seat 53, and fixture angle fixation kit 54 is a fixed pan 541 towards location mistake proofing through hole 531 1 sides.The effect of fixed pan 541 is: with the plane contact on axle middle part 912 outer peripheral faces of trunnion shaft body 91, preferably contact with two upper anchor points 95 on axle middle part 912 outer peripheral faces of trunnion shaft body 91.The object of such design is: prevent that trunnion shaft body 91 is in the 531 interior rotations of location mistake proofing through hole, thereby trunnion shaft body 9 is fixed in location mistake proofing through hole 531, improved the intensity that clamps of trunnion shaft fixture 500.
Sleeve locating shaft 55 is fixed on the end face of fixture angle fixation kit 54, and vertical with the end face of fixture angle fixation kit 54.Positioning through hole 923 internal diameters on the sleeve edge 922 at the external diameter of sleeve locating shaft 55 and the sleeve of trunnion shaft 92 tops equate.
Because the sleeve joint hole 921 of sleeve 92 is when axle top 913 socket with trunnion shaft body 91, its positioning through hole 923 is also fixing with sleeve locating shaft 55, and the bottom surface of sleeve edge 922 contacts with the end face of fixture angle fixation kit 54 simultaneously, so sleeve 92 is fixed.
Meanwhile, two angle type handles 56 are fixed on lower location-plate 51 face-to-face by handle keyset 57, are convenient to dismounting and the carrying of trunnion shaft fixture 500.
Simultaneously the first station is provided with and is positioned at the vertically sleeve pad testing agency assembly 102 of top of trunnion shaft fixture 500, and sleeve pad testing agency assembly 102 is provided with a blind hole (not shown) on sleeve 92 outer peripheral faces that can be socketed in trunnion shaft.If it is correct that the sleeve of trunnion shaft 92 and pad 93 installed, this blind hole can with the outer peripheral face socket of sleeve 92, meanwhile, the end face of this blind hole can also contact with the end face of the sleeve edge 922 of sleeve 92.If sleeve 92 and pad 93 setup errors, this blind hole cannot be socketed with the outer peripheral face of sleeve 92.
