The belt pulley rapid installation device
Technical field
The utility model relates to a kind of assembling device of generator internal part, relates in particular to the belt pulley rapid installation device in the generator.
Background technology
At present, when being installed to belt pulley on the generator shaft, generally all be through manually the belt pulley assembly being pressed into dynamo bearing, consume power relatively and workload is big.Simultaneously, in assembling process manually, if unbalanced, cause the damage of dynamo bearing or belt pulley assembly easily, and this assembly cost manually is high, can't carry out streamline production to the belt pulley assembly or the dynamo bearing application of force.
Summary of the invention
In order to overcome the deficiency of prior art, the purpose of the utility model is to provide a kind of assembling speed fast and guarantee the belt pulley rapid installation device of assembly quality.
The utility model belt pulley rapid installation device, it comprises frame, frame one side horizontal fixed has cylinder; The cylinder end is provided with top board; Top board is arranged with the top cover outward, and generator is fixed on the frame opposite side, and the center of top cover and the center of dynamo bearing are on a horizontal line; The belt pulley assembly is set on the dynamo bearing, and is inserted in dynamo bearing by cylinder drive top cover roof pressure.
Said top cover internal diameter is greater than belt pulley assembly external diameter.
The air inlet end of said cylinder is provided with choke valve.
Adopt the belt pulley rapid installation device of the utility model; Manually the belt pulley assembly being changed existing manual over to dynamo bearing changes the cylinder automation into the belt pulley assembly is pushed dynamo bearing; Improved pack into the speed of dynamo bearing of belt pulley assembly greatly; Practice thrift the production time, improved production efficiency, reduce production costs.Simultaneously, the fit of this automation has also improved the assembly quality of belt pulley assembly and dynamo bearing.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation:
Fig. 1 is the structural representation of the utility model belt pulley rapid installation device.
Embodiment
As shown in Figure 1, the utility model belt pulley rapid installation device, it comprises frame 1; Frame 1 one side horizontal fixed have cylinder 2, and cylinder 2 ends are provided with top board 3, the top board 3 outer top covers 4 that are arranged with; Generator 5 is fixed on frame 1 opposite side; The center of top cover 4 and the center of dynamo bearing 6 are on a horizontal line, and belt pulley assembly 7 is set on the dynamo bearing 6, and are inserted in dynamo bearing 6 by cylinder 2 drive top cover 4 roof pressures.
4 internal diameters are overlapped greater than belt pulley assembly 7 external diameters in said top.
The air inlet end of said cylinder 2 is provided with choke valve 8.
When assembling belt pulley assembly 7 and dynamo bearing 6; Earlier belt pulley assembly 7 is enclosed within on the dynamo bearing 6; To push up cover 4 then and aim at belt pulley assembly 7; By the pressure of choke valve 8 control cylinders 2 and press down speed, drive top cover 4 by cylinder 2 and automatically belt pulley assembly 7 is pressed into dynamo bearing 6 again.
