Abstract
The invention relates to a press fitting mechanism for a bolt of a tractor driving shaft. The press fitting mechanism comprises a pressing machine, wherein the pressing machine is provided with a pressing machine seat and a pressing head, the pressing machine seat is provided with a press fitting base, an upper sleeve is arranged below the pressing head, the lower end of the upper sleeve is connected with a lower sleeve, and the lower end of the lower sleeve is provided with an annular pressing plate corresponding to a screwed hole in a flange disc of the driving shaft. The press fitting mechanism can be used for pressing eight bolts at the same time and pressing the bolts in place in one step, is applicable to large batch production and favorable for improving the production efficiency and has an obvious effect, and the upper sleeve and the lower sleeve are connected in a movable sleeved mode, and the press fitting mechanism is simple in structure, accurate in positioning, convenient to operate and good in applicability and is favorable for reducing the labor intensity of operators in mounting and dismounting.
Description
Technical field
The present invention relates to a kind of tractor dedicated set mounting mechanism, particularly a kind of press fitting mechanism for bolt of tractor driving shaft.
Background technology
What adopt between tractor final drive driving wheel set bolt and drive shaft hole is interference fit, mostly adopts hand assembled in prior art, because the magnitude of interference is larger, so production efficiency is very low, is not easy to knock the position.Every tractor has 16 such bolts, by hand rings very difficult, rings very hard, is not suitable with production demand.
Summary of the invention
The purpose of this invention is to provide a kind of above-mentioned shortcoming that overcomes, easy to assembly, the press fitting mechanism for bolt of tractor driving shaft that production efficiency is high.
The technical scheme that realizes the object of the invention is: a kind of press fitting mechanism for bolt of tractor driving shaft, has press, press has press bed and pressure head, described support is provided with and press-fits base, the pressure head below is provided with upper bush, the upper bush lower end connects lower sleeve, and the lower sleeve lower end is provided with the ring platen corresponding with driving shaft ring flange screw.
Adopt the mode of pivot bush unit to be connected between the upper bush of above-mentioned press fitting mechanism for bolt of tractor driving shaft and lower sleeve.
The lower sleeve of above-mentioned press fitting mechanism for bolt of tractor driving shaft is integrated part with the ring platen.
The present invention has positive effect: the present invention can also can once be press-fit into place by eight bolts of synchronous press mounting, can adapt to production in enormous quantities, enhance productivity, and successful; Adopt the mode of pivot bush unit to connect between the sleeve of up and down, simple in structure, accurate positioning, easy to operate, applicability is good, reduces operative employee's dismounting labour intensity.
Description of drawings
Content of the present invention is easier to be expressly understood in order to make, and the below is according to specific embodiment and by reference to the accompanying drawings, and the present invention is further detailed explanation, wherein
Fig. 1 is structural representation of the present invention.
The specific embodiment
See Fig. 1, the present invention has press 1, and press 1 has press bed 11 and pressure head 12; Support 11 is provided with and press-fits base 2, pressure head 12 belows are provided with upper bush 3, upper bush 3 lower ends connect lower sleeve 4, lower sleeve 4 lower ends are provided with the ring platen 41 corresponding with driving shaft ring flange 9 screws, adopt the mode of pivot bush unit to be connected between upper bush 3 and lower sleeve 4, lower sleeve 4 is integrated part with ring platen 41.
during operation, first the ring flange 9 of driving shaft is placed on downwards and press-fits on base 2, eight bolts 8 to be press-fited are placed in the corresponding mounting hole, the top of the ring platen 41 of lower sleeve 4 being placed and is aligned in eight bolts 8 is socketed in upper bush 3 on lower sleeve 4 again, start press 1, the pressure head 12 of press moves down conflict to upper bush 3 tops, at the ring platen 41 by lower sleeve 4, eight bolt synchronous press mountings under it are put in place, complete and press-fit, then move on pressure head 12, take off upper bush 3 and lower sleeve 4, to press-fit good workpiece removes again, change another workpiece to be press-fited, the circulation above-mentioned steps.
Above-described specific embodiment; purpose of the present invention, technical scheme and beneficial effect are further described; institute is understood that; the above is only specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any modification of making, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
