Abstract
The invention discloses a variable distance mechanism of a double-shaft tightening machine, characterized in that it includes: a lower boxboard, on which straight guide rail is arranged along the Y axis; a pair of shift sliding plates, being able to slide toward each other on the straight guide rail of the lower boxboard; a pair of tightening axles, respectively fixedly arranged in the axle holes of the pair of shift sliding plates. By adopting the straight line movement of the shift sliding plates on the lower box board, the invention realizes the variable distance between a pair of tightening axles, which is simple in structure and easy to realize. By changing the shape of sliding chute on the pulling plate, the motion trail of the axis pin is changed to obtain switch of variable center distance values so as to satisfy the tightening of bolt sets of different center distances. It is highly adaptable.
Description
Technical field
The present invention relates to the automobile main reducer bearing (ball) cover and tighten bending moment mechanism, more specifically saying so needs the conversion of centre-to-centre spacing of the twin shaft of the process that twin shaft tightens for accomplishing bearing (ball) cover assembling or any, thereby accomplishes tightening of different centre-to-centre spacing bolts.
Background technology
In the bearing (ball) cover assembling process of drive axle main reducing gear, or the process of what is the need for and wanting bolt to tighten in office, twin shaft is tightened and is widely used.From adapting to the scope of product, the twin shaft tightening machine has two kinds of forms, and a kind of is specially to certain product design; Its centre-to-centre spacing of tightening axle is non-adjustable, in the time need tightening the bolt of different model product, because of the variation of its centre-to-centre spacing position; Fix and tighten a wheelbase; Thereby the bolt that can not satisfy the different centre-to-centre spacing of different product tightens, and can only purchase the supporting with it use of equipment that difference is tightened wheelbase, increased the equipment input thus greatly; Another kind is that the centre-to-centre spacing of tightening axle can be regulated within the specific limits, makes it can be used for tightening bolt group through adjusting with having different centre-to-centre spacing.But in prior art, the adjusting of tightening shaft position is not only loaded down with trivial details but also inaccurate, thereby influences operating efficiency and tighten quality.
Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology weak point; A kind of twin shaft screw down distance-variation mechanism is provided; Centre-to-centre spacing with the adjustment twin shaft of efficiently and accurately; Make tightening machine can tighten the bolt group of different centre-to-centre spacing, thus the bolt that makes tightening machine can adapt to multiple product tighten, have bigger flexibility.
Technical solution problem of the present invention adopts following technical scheme:
The design feature of twin shaft screw down distance-variation of the present invention mechanism is in boxboard upper edge Y direction down line slideway to be set; Can be in the driving lower edge of the sled drive mechanism said line slideway slippage in opposite directions of boxboard down of a pair of displacement slide plate; The a pair of axle of tightening that runs through the displacement slide plate is fixedly installed on respectively in the axis hole of a pair of displacement slide plate.
The design feature of twin shaft screw down distance-variation of the present invention mechanism also is:
Said sled drive mechanism is set to: on the symmetric position of a pair of displacement slide plate, be fixedly welded with the bearing pin that protrudes out along Z-direction respectively; Be provided with and the relatively-stationary feather key plate of following boxboard, said feather key plate has " eight " font slideway, and an arm-tie is that key is connected with the feather key plate, can form relatively moving of X-direction between said arm-tie and the feather key plate; Said arm-tie is provided with the arm-tie chute, and said arm-tie chute is an inner side edge with " eight " font slideway on the said feather key plate, and said bearing pin is positioned at said arm-tie chute; Relatively moving of X-direction is to be actuator with said arm-tie between arm-tie and the feather key plate.
The arm-tie cylinder is set, and the cylinder mounting plate that is used to install the arm-tie cylinder is fixedly installed on down boxboard, and said feather key plate is connected with the cylinder mounting plate bolt, and said arm-tie is connected with the drive end of arm-tie cylinder.
Compared with present technology, beneficial effect of the present invention is embodied in:
1, the present invention moves with displacement slide plate straight line on following boxboard to realize a pair of displacement between the axle of tightening, and is simple in structure, is easy to realize;
2, the present invention can change the movement locus of bearing pin through the shape that changes the chute on the arm-tie, obtains the conversion of different centre-to-centre spacing values, and to satisfy tightening of different centre-to-centre spacing bolt groups, adaptability is strong;
3, the present invention adopts moving of slide plate cylinder control displacement slide plate, can realize the Automatic Control of cylinder, easy to operate quick, accurate positioning.

Fig. 3 cooperates sketch map for middle guide briquetting of the present invention with line slideway;
Label among the figure: 1 directional bond; 2 guide rail briquettings; 3 displacement slide plates; 4 slide plate briquettings; 5 arm-ties; 6 feather key plates; 7 pins; 8 line slideways; 9 times boxboards; 10 cylinder mounting plates; 11 arm-tie cylinders; 12 tighten axle.
The specific embodiment
Referring to Fig. 1, Fig. 2, the structure setting in the present embodiment is in following boxboard 9 upper edge Y directions line slideway 8 to be set; A pair of displacement slide plate 3 can be under the driving lower edge of sled drive mechanism line slideway 8 slippage in opposite directions of boxboard 9; The a pair of axle 12 of tightening that runs through displacement slide plate 3 is fixedly installed on respectively in the axis hole of a pair of displacement slide plate 3.
In the practical implementation, sled drive mechanism is set to: on the symmetric position of a pair of displacement slide plate 3, be fixedly welded with the bearing pin 7 that protrudes out along Z-direction respectively; Be provided with and following boxboard 9 relatively-stationary feather key plates 6, feather key plate 6 has " eight " font slideway, and an arm-tie 5 and feather key plate 6 can form relatively moving of X-direction for key is connected between arm-tie 5 and the feather key plate 6; Arm-tie 5 is provided with the arm-tie chute, and the arm-tie chute is an inner side edge with " eight " font slideway on the feather key plate 6, and bearing pin 7 is positioned at the arm-tie chute; Relatively moving of X-direction is to be actuator with arm-tie 5 between arm-tie 5 and the feather key plate 6; In order to drive arm-tie 5, arm-tie cylinder 11 is set, the cylinder mounting plate 10 that is used to install arm-tie cylinder 11 is fixedly installed on down boxboard 9, and feather key plate 6 is connected with cylinder mounting plate 10 bolts, and arm-tie 5 is connected with the drive end of arm-tie cylinder 11.
Like Fig. 1, Fig. 2 and shown in Figure 3, in the practical implementation, the corresponding structure setting also comprises:
The course of work:
Behind the replacement of products that needs are tightened, the centre-to-centre spacing of the bolt group that will tighten on it also changes, and will change the centre-to-centre spacing of tightening axle 12 this moment.Driving arm-tie 5 by arm-tie cylinder 11 moves forward and backward; Bearing pin 7 in arm-tie 5 chutes moves according to the track of chute simultaneously; Driving displacement slide plate 3 slides on line slideway 8 relatively; On it two tighten axle 12 and also will slide relatively, realize that tightening spools 12 for two is converted to another centre-to-centre spacing value from a centre-to-centre spacing value.Realize different product can be on same machine the completion of efficiently and accurately.
