Abstract
The utility model 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 a 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 increasing the production efficiency and has an obvious effect; and the upper sleeve and the lower sleeve are connected in a movable sleeving manner, 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 utility model relates to a kind of tractor dedicated set mounting mechanism, particularly a kind of tractor driving shaft bolt press-loading device.
Background technology
What adopt between tractor final drive driving wheel set bolt and the drive shaft hole is interference fit, mostly adopts hand assembled in the prior art, because the magnitude of interference is bigger, so production efficiency is very low, is not easy to strike and puts in place.Every tractor has 16 such bolts, by hand rings very difficulty, ring very hard, the incompatibility production demand.
The utility model content
The purpose of the utility model provides a kind of above-mentioned shortcoming that overcomes, and is easy to assembly, the tractor driving shaft bolt press-loading device that production efficiency is high.
The technical scheme that realizes the utility model purpose is: a kind of tractor driving shaft bolt press-loading device; Has press; Press has press bed and pressure head, and said support is provided with and press-fits base, and 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 and the corresponding ring platen of driving shaft ring flange screw.
Adopt the mode of pivot bush unit to be connected between the upper bush of above-mentioned tractor driving shaft bolt press-loading device and the lower sleeve.
The lower sleeve of above-mentioned tractor driving shaft bolt press-loading device is an integral piece with the ring platen.
The utlity model has positive effect: the utility model can press-fit eight bolts simultaneously and can once be press-fit into place, and can adapt to production in enormous quantities, enhances productivity, and effect is obvious; Adopt the mode of pivot bush unit to connect up and down between the sleeve, simple in structure, accurate positioning, easy to operate, applicability is good, reduces operative employee's dismounting labour intensity.
Description of drawings
For the content that makes the utility model is expressly understood more easily,, the utility model is done further detailed explanation, wherein below according to specific embodiment and combine accompanying drawing
Fig. 1 is the utility model structural representation.
The specific embodiment
See Fig. 1, the utlity model has press 1, 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 and the corresponding ring platen 41 of driving shaft ring flange 9 screws, adopt the mode of pivot bush unit to be connected between upper bush 3 and the lower sleeve 4, and lower sleeve 4 is an integral piece with ring platen 41.
During operation, first ring flange 9 with driving shaft is placed on downwards and press-fits on the base 2, and 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 the lower sleeve 4 again, starts press 1, and the pressure head 12 of press moves down upper bush 3 tops of conflicting; Ring platen 41 through lower sleeve 4 is press-fit into place eight bolts under it simultaneously, and completion press-fits, and moves on the pressure head 12 then; Take off upper bush 3 and lower sleeve 4; To press-fit good workpiece again and remove, change another workpiece to be press-fited, the circulation above-mentioned steps.
Above-described specific embodiment; Purpose, technical scheme and beneficial effect to the utility model have carried out further explain, it should be understood that the above is merely the specific embodiment of the utility model; Be not limited to the utility model; All within the spirit and principle of the utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
