Description

It is fitted close Press fitting provision for disengagement and application method
Technical field
Press fitting provision for disengagement and application method are fitted close the present invention relates to one kind, belongs to the fatigue examination of engineering structure node Test research field.
Background technology
In the industrial production, there is substantial amounts of tight fit among many mechanisms, these are fitted close part dismounting difficulty, in order to Dismantling these interference fits needs to expend a large amount of manpower and materials, and is easily caused whole equipment scrapping during dismounting.
The content of the invention
The purpose of the present invention is to be fitted close Press fitting provision for disengagement there is provided one kind for above weak point and use Method.
The scheme that present invention solution technical problem is used is that one kind is fitted close Press fitting provision for disengagement, including pull bar, The pull bar both sides are symmetrically arranged with two drag hooks, and drag hook upper end rotates with pull bar and is connected, and drag hook lower end sets hook portion, the drawing Set in the middle part of bar and traction screw is provided with screw, screw, traction screw lower end is provided with butting section, traction screw upper end is set There is handwheel.
Further, it is vertically arranged with before and after slot to make way, slot to make way to be symmetrically arranged with the middle part of the pull bar left and right sides and takes Access slot, overlap joint groove is from tie rod end to middle part arranged for interval, and the drag hook upper end, which is provided with pin-and-hole, pin-and-hole, is provided with support Pin, supporting pin both ends are ridden upon in overlap joint groove.
Further, the handwheel periphery is provided with for non-slip texture.
A kind of application method for being fitted close Press fitting provision for disengagement:The relative position of two drag hooks is adjusted, drag hook is led to Cross supporting pin to ride upon in suitable overlap joint groove, allow the hook portion of drag hook lower end to catch on part, rotate handwheel so that under traction screw Move, the butting section of traction screw lower end props up part end face so that hook portion firmly catches on part, then pull pull bar to tear part open It is lower.
Compared with prior art, the invention has the advantages that:It is simple in construction, it is reasonable in design, for interference fit Dismounting it is largely effective, removal efficiency is high, reliable operation, and worth enterprise widelys popularize.
Brief description of the drawings
Patent of the present invention is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the invention.
In figure:
1- pull bars, 2- drag hooks, 3- traction screws, 4- handwheels, 5- hook portions, 6- butting sections, 7- slots to make way, 8- overlap joint grooves, 9- supports Pin, the part that 10- is disassembled.
Embodiment
The present invention is further described with reference to the accompanying drawings and detailed description.
As shown in figure 1, a kind of be fitted close Press fitting provision for disengagement, including pull bar, the pull bar both sides are symmetrically arranged with Two drag hooks, drag hook upper end rotates with pull bar and is connected, and drag hook lower end sets and set in the middle part of hook portion, the pull bar in screw, screw Traction screw is provided with, traction screw lower end is provided with butting section, and traction screw upper end is provided with handwheel.
In the present embodiment, allowed to adapt to be vertically arranged with the middle part of part of different sizes, the pull bar left and right sides Overlap joint groove is symmetrically arranged with before and after position groove, slot to make way, overlap joint groove is from tie rod end to middle part arranged for interval, and the drag hook upper end is set It is equipped with pin-and-hole, pin-and-hole and is provided with supporting pin, supporting pin both ends is ridden upon in overlap joint groove.
In the present embodiment, the handwheel periphery is provided with for non-slip texture.
A kind of application method for being fitted close Press fitting provision for disengagement:The relative position of two drag hooks is adjusted, drag hook is led to Cross supporting pin to ride upon in suitable overlap joint groove, allow the hook portion of drag hook lower end to catch on part, rotate handwheel so that under traction screw Move, the butting section of traction screw lower end props up part end face so that hook portion firmly catches on part, then pull pull bar to tear part open It is lower.
The object, technical solutions and advantages of the present invention are further described by above-listed preferred embodiment, are answered Understand, the foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention God is with principle, and any modification, equivalent substitution and improvements made etc. should be included in the scope of the protection.
