Description
Technical field
The utility model relates to shaft press-fitting tool.
Background technology
Concrete mixer is widely used in highway construction, and it can continuous stirring produces the concrete finished product of various ratio compositions.Existing concrete mixer generally comprises mixing drum and rotates and is assemblied in the shaft device in mixing drum, shaft device comprises that shaft and interval are fixed on the retainer ring on shaft, shaft two ends are rotated and are assemblied on corresponding bearing block, and rotated by driven by motor by gear drive, fixing assembling stirring vane on retainer ring, for stirring concrete.During shaft assembling, need in advance cutting ferrule or bearing etc. to be provided with on the sheathed corresponding axle journal that is fixed to shaft of the annular element of installing hole, but, because shaft is thick and weight is very large, therefore the size of cutting ferrule and bearing, weight are also larger, move difficulty, easy fitted not during installation, labor strength is very large, and is easily injured by a crashing object or weigh wounded.Meanwhile, after cutting ferrule and bearing are set on retainer ring, installation process is the hammerings that adopt more, waste time and energy and can't guarantee installation accuracy, and in installation process, swinging easily appears in shaft, to installation, brings very big inconvenience.
Utility model content
The purpose of this utility model is to provide a kind of shaft press-fitting tool, cutting ferrule or bearing can be overlapped easily and is set on shaft, and assembling realizes semi-automation.
The technical scheme that the utility model shaft press-fitting tool adopts is: shaft press-fitting tool, comprise base, the two ends of described base length direction are fixed with respectively ejector apparatus and top headstock, be also provided with for corresponding shaft horizontal support and be placed into the shaft bearing between described ejector apparatus and top headstock on base; Described ejector apparatus has horizontal extension end, described horizontal extension end is provided with for overlapping the sleeve of the corresponding end that is set to shaft, described sleeve has for pushing up the corresponding cutting ferrule of pressure or bearing makes cutting ferrule or bearing holder (housing, cover) be set to the annular end face on shaft, and described top headstock has one end stopping surface that block is located vertically away from ejector apparatus for shaft.
Described sleeve comprises cylindrical shell and is fixed on the mount pad of cylinder back-end, and described sleeve is by the removable output that is fixed on described ejector apparatus of described mount pad.
Described shaft bearing is Y shape, its top have that two intervals arrange and for symmetric support at the shaft support roller of both sides radially.
Described ejector apparatus is the horizontal hydraulic machine that is provided with horizontal extension bar.
The utility model adopts technique scheme, and on base, the two ends of length direction are fixed with respectively ejector apparatus and top headstock, and shaft bearing can be placed between ejector apparatus and top headstock for corresponding shaft horizontal support; The stopping surface of top headstock can carry out block away from one end of ejector apparatus vertically to shaft, realizes the axial location to shaft, and while avoiding ejector apparatus ejection, shaft is moved; Sleeve on the horizontal extension end of ejector apparatus has for pushing up the corresponding cutting ferrule of pressure or bearing makes cutting ferrule or bearing holder (housing, cover) be set to the annular end face on shaft, cutting ferrule can be promoted or bearing moves, and the middle bore portion of sleeve can overlap the corresponding end that is set to shaft, thereby in ejection process, dodge shaft, cutting ferrule or bearing are pushed into desired location.Compared with prior art, this frock has avoided beaing operation, press-fits process and by ejector apparatus, is completed completely, time saving and energy saving, and cutting ferrule or bearing can uniform stresseds, guarantees installation accuracy, easy to operate, has realized semi-automatic assembling.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of the utility model shaft press-fitting tool;
Fig. 2 is the schematic diagram of cutting ferrule in Fig. 1.
The name that in figure, each Reference numeral is corresponding is called: 1 base, 2 horizontal hydraulic machines, 21 telescopic shafts, 3 sleeves, 31 cylindrical shells, 32 mount pads, 4 top headstocks, 5 shaft bearings, 51 support rollers, 6 shafts, 7 cutting ferrules.
The specific embodiment
An embodiment of the utility model shaft press-fitting tool is as shown in Fig. 1-Fig. 2, comprise base 1, one end of described base 1 length direction is fixed with horizontal hydraulic machine 2 as ejector apparatus, and the other end of base 1 length direction is fixed with the top headstock 4 of vertical setting.Between horizontal hydraulic machine 2 and top headstock 4, be also fixed with shaft bearing 5, this shaft bearing 5 is Y shape, its top have that two intervals arrange and for symmetric support at shaft 6 support roller 51 of both sides radially, when two shaft bearings 5 are used respectively with the first half of corresponding shaft 6 and latter half of corresponding, corresponding shaft 6 horizontal supports are placed between horizontal hydraulic machine 2 and top headstock 4.
Horizontal hydraulic machine 2 has telescopic shaft 21 that can along continuous straight runs stretching motion, and the end of telescopic shaft 21 is provided with for overlapping the sleeve 3 of the corresponding end that is set to shaft 6.Described sleeve 3 comprises cylindrical shell 31 and the mount pad 32 that is fixed on cylindrical shell 31 rear ends, and the front end of telescopic shaft 21 is plugged in the corresponding blind hole on mount pad 32 and relies on corresponding holding screw removable fixing.Cylindrical shell 31 has for pushing up the corresponding cutting ferrule 7 of pressure or bearing makes cutting ferrule 7 or bearing holder (housing, cover) be set to the annular end face on shaft 6, the hollow space of sleeve 3 can overlap in the corresponding end that is set to shaft 6, while avoiding sleeve 3 to move and the axle journal of shaft 6 interfere, thereby make to need the cutting ferrule 7 of assembling can be pushed to desired location.Top headstock 4 has one end stopping surface that block is located vertically away from ejector apparatus for shaft 6, can prevent from press-fiting shaft 6 in process and move axially.
During use, controlling horizontal hydraulic machine 2 retracts sleeve 3, shaft 6 is transferred on shaft bearing 5, make shaft 6 horizontal supports at sleeve 3 and come directly towards between pedestal and its axis is overlapped with horizontal hydraulic machine 2 the axial of telescopic shaft 21, adjusting shaft 6 tops, Shi Qi one end, position is pressed on the pedestal of top, then cutting ferrule 7 is preloaded onto on the axle journal of shaft 6 respective end, the telescopic shaft 21 of controlling horizontal hydraulic machine 2 extends, making sleeve 3 move forward and rely on annular end face to hold out against cutting ferrule 7 slowly moves forward cutting ferrule 7, move to and control telescopic shaft 21 after desired location and return, cutting ferrule 7 can be installed on shaft 6.Sleeve 3 by transposing different size, can also assemble cutting ferrule 7 or the bearing of different model, easy to use, time saving and energy saving.Certainly, in the above-described embodiments, ejector apparatus also can replace to other structures, such as hydraulic cylinder, pneumatic cylinder, electric pushrod etc.
