Abstract
The utility model relates to a rubber busing press fitting device comprising a fixing workbench. A fixed positioning pin, an elastic positioning pin and a hydraulic oil cylinder are sequentially arranged on the fixing workbench. Output ends of the fixed positioning pin, the elastic positioning pin and the hydraulic oil cylinder are coaxial. The two pins are used for positioning and guiding the axes of large-span parts, and the hydraulic element is used for pressing rivets, so that form and position tolerances during press fitting and after press fitting are guaranteed.
Description
Technical field
The utility model relates to a kind of rubber bushing press-mounting instrument, and specifically a kind of a plurality of coaxial composite bush that are applied to solve heavy parts press-fits problem.
Background technology
A plurality of bushing press-mounting of current heavy parts is only located single part hole, for same direction press-fits,, simultaneously to location, a plurality of hole, so just do not cause in bushing coining process, locating hole being offset, thereby cause car load to be installed, go wrong or the difficult installation of car load.
Utility model content
The utility model has proposed a kind of energy and has met the Geometrical Tolerance Principle after press-fiting in order to solve Geometrical Tolerance Principle (axiality, the depth of parallelism require) after the press-fiting and press-fit of rubber bushing of large span part, and accurate positioning operating aspect rubber bushing press-mounting workpiece.
The technical solution adopted in the utility model is: a kind of rubber bushing press-mounting instrument, comprise stationary work-table, and it is characterized in that: on stationary work-table, be provided with successively fixed fastening screw, elastic positioning pin and hydraulic jack; The output of fixed fastening screw, elastic positioning pin and hydraulic jack is coaxial.
Preferably, described fixed fastening screw comprises latch body and holder, and described latch body is connected with holder dismounting, and holder is located on stationary work-table; At latch body two ends, be respectively equipped with diameter and equal the work end of workpiece installing hole internal diameter and the lining end that diameter equals rubber bushing internal diameter.
Preferably, described elastic positioning pin comprises two-part external part, i.e. the first external part and the second external part, the diameter of described the first external part equals the internal diameter of rubber bushing, and the diameter of described the second external part equals to install on workpiece the internal diameter of the installing hole of rubber bushing.
The beneficial effects of the utility model: large span axis of workpiece is positioned, led by two alignment pins, by Hydraulic Elements, complete the action that presses simultaneously, effectively guaranteed the Geometrical Tolerance Principle after press-fiting and press-fiting, can also to two ends, press-fit rubber bushing successively simultaneously.It has met large span part rubber bushing installation requirement completely, and accurate positioning is simple, convenient.
