Abstract

The utility model discloses a bearing pressing device of a motor rotor assembly line relating to the motor production technology field. The device can be used to solve the technical problems of reducing costs, occupied space, labor intensity, and improving operation safety performance and pressing quality. The device comprises a pressing support, a cylinder, and a bearing seat. The bearing seat is fixedly disposed on the pressing support, and an upper end of the bearing seat is provided with a pit, which is recessed downwardly, and is a bearing positioning pit, in addition, the bearing can be disposed in the pit. The cylinder is disposed on the pressing support, and a power arm faces vertically downwards, and a lower end of the power arm is fixedly provided with a pressing block. The briquetting is disposed right above the bearing positioning pit, and a working chamber of the cylinder is connected with a high pressure gas source of the motor rotor assembly line through an air valve. The device provided in the utility model is suitable for the motor rotor assembly line provided with the high pressure gas source.

Description

The bearing press-fitting device of rotor assembling line
Technical field
The utility model relates to motor manufacturing technology, particularly relates to a kind of technology of bearing press-fitting device of rotor assembling line.
Background technology
All be equipped with high-pressure air source in the rotor assembling line, and be equipped with for the bearing press-fitting device of bearing press mounting to the rotating shaft.
All employings hydraulic jack of the bearing press-fitting device that is equipped with in the existing rotor assembling line is as main driver part, therefore be necessary for hydraulic jack configuration hydraulic oil container, so that the input cost of existing bearing press-fitting device is higher, and it is also larger to install shared space.
In addition, existing bearing press-fitting device is when the pressing bearing operation, operating personnel first will be to be press-fited bearing be placed on the bearing pedestal of hydraulic jack below, arrest bearing with hand again it is aimed at the rotating shaft lower end of rotor, and then on the rotating shaft by the pushing of the briquetting on hydraulic jack power arm rotor, make the rotating shaft lower end insert the centre bore of bearing, this bearing press mounting mode is owing to need staff to arrest bearing when the rotating shaft lower end is pressed into the bearing centre hole, therefore operating personnel are existed potential safety hazard, and labour intensity is also larger, the bearing press mounting quality also is difficult to guarantee, deviation occurs easily.
The utility model content
For the defective that exists in the above-mentioned prior art, technical problem to be solved in the utility model provide a kind of cost low, take up room little, processing safety is high, and can reduce labor intensity of operating staff, improve the bearing press-fitting device of the rotor assembling line of bearing press mounting quality.
In order to solve the problems of the technologies described above, the bearing press-fitting device of a kind of rotor assembling line provided by the utility model is provided with high-pressure air source in the described rotor assembling line, and this device comprises and press-fits support, driver part, bearing pedestal; It is characterized in that: described driver part is cylinder;
Described bearing pedestal is fixed on and press-fits on the support, and the bearing pedestal upper end is provided with a pit that supplies bearing to insert to lower recess, and this pit is the bearing positioning pit;
Described cylinder is installed in and press-fits on the support, and its power arm is vertically towards the below, and its power arm lower end is fixed with a briquetting, this briquetting be positioned at the bearing positioning pit directly over, the working chamber of cylinder is received high-pressure air source in the rotor assembling line through air valve.
The bearing press-fitting device of the rotor assembling line that the utility model provides, adopt cylinder as main driver part, can utilize in the rotor assembling line other device institute high-pressure air source that is equipped with as power source, need not to dispose separately extra power source, therefore its cost is lower, it is also less to take up room, and be provided with the bearing positioning pit in bearing pedestal upper end, only need during the pressing bearing operation bearing is put into the bearing position hole, can make the bearing centre hole aim at the rotating shaft lower end of rotor, when being pressed into the bearing centre hole, the rotating shaft lower end no longer need staff to help bearing, its processing safety is higher, can reduce labor intensity of operating staff, improve the bearing press mounting quality.
Description of drawings
Fig. 1 is the structural representation of bearing press-fitting device of the rotor assembling line of the utility model embodiment;
Fig. 2 is the use schematic diagram of the bearing press-fitting device of the utility model embodiment rotor assembling line.
Embodiment
Below in conjunction with description of drawings embodiment of the present utility model is described in further detail, but present embodiment is not limited to the utility model, every employing analog structure of the present utility model and similar variation thereof all should be listed protection range of the present utility model in.
As shown in Figure 1, the bearing press-fitting device of a kind of rotor assembling line that the utility model embodiment provides is provided with high-pressure air source in the described rotor assembling line, and this device comprises and press-fits support 1, driver part, bearing pedestal 3; It is characterized in that: described driver part is cylinder 2;
Described bearing pedestal 3 is fixed on and press-fits on the support 1, and bearing pedestal 3 upper ends are provided with a pit 31 that supplies bearing to insert to lower recess, and this pit 31 is the bearing positioning pit;
Described cylinder 2 is installed in and press-fits on the support 1, its power arm 21 is vertically towards the below, and its power arm 21 lower ends are fixed with a briquetting 4, this briquetting 4 be positioned at bearing positioning pit 31 directly over, the working chamber of cylinder 2 is received high-pressure air source in the rotor assembling line through air valve.
The using method of the utility model embodiment is as follows:
As shown in Figure 2, bearing 5 that first will be to be press-fited is inserted the bearing positioning pit of bearing pedestal 3 upper ends, rotor 6 with bearing to be installed places between the briquetting 4 of bearing pedestal 3 and cylinder power arm lower end again, and the rotating shaft 61 of rotor 6 is kept vertically, the lower end of rotating shaft 61 props up the centre bore of the bearing 5 in the bearing positioning pit, then the power arm by Air Valve Control cylinder 2 stretches out downwards, the briquetting 4 of cylinder power arm lower end namely pushes rotating shaft 61 upper ends of rotor 6 downwards, make rotating shaft 61 lower ends insert the centre bore of bearing 5, then upwards retract by the power arm of Air Valve Control cylinder 2, the briquetting 4 of cylinder power arm lower end also upwards is retracted to initial position thereupon, and can take off the rotor 6 that has press-fited bearing this moment from press-fiting support.
