Description
Technical field
The utility model relates to a kind of improvement invention of concrete vibration bar of electric motor built-in.
Background technology
Concrete vibration bar is the indispensable instrument of concreting, is widely used in building trade.The concrete vibration bar that uses in the engineering at present, major part still adopts the structure of electric machine external formula, drive the purpose that the built-in planet tapper of vibrating head moves to reach the vibrating head vibration at high speed by common asynchronous motor by flexible axle, but the shortcoming of electric machine external formula vibrating head is: application life is short, noise is large, and operating personnel's labour intensity is large, and energy consumption is large, efficient is very low, also has the failure of oscillation phenomenon.So, the concrete vibration bar that has occurred electric motor built-in on the market, the electric motor built-in concrete vibration bar efficiently solves the above-mentioned shortcoming of electric machine external formula concrete vibration bar, its structure is: comprise the rod cover, lower cone, upper cover, stator core winding, the magnet steel ring, rotating shaft and eccentric block, lower cone is connected to the lower end of rod cover, upper cover is connected to the upper end of rod cover, the rod cover has the hollow circular cylinder structure, stator core winding, rotating shaft and eccentric block are installed in rod cover endoporus, eccentric block is welded in the rotating shaft and is structure as a whole with rotating shaft, rotating shaft is by a plurality of rollers and ball bearing supporting in parallel, and magnet steel ring fixed cover is located in the rotating shaft.Because eccentric block and the integrally welded structure of rotating shaft of electric motor built-in concrete vibration bar, so that the assembling of whole vibrating head just seems is loaded down with trivial details, the replacing after the damage parts is very inconvenient, and the while eccentric block can not be according to required independent replacing.
Summary of the invention
In view of the deficiencies in the prior art, the utility model provides that a kind of assembling is simple, part exchanging electric motor built-in concrete vibration bar easily.
For solving the problems of the technologies described above, the utility model takes following technical scheme to finish:
The electric motor built-in concrete vibration bar, comprise the rod cover, lower cone, upper cover, stator core winding, the magnet steel ring, rotating shaft and eccentric block, lower cone is connected to the lower end of rod cover, upper cover is connected to the upper end of rod cover, the rod cover has the hollow circular cylinder structure, stator core winding, rotating shaft and eccentric block are installed in rod cover endoporus, the rotating shaft two ends are provided with bearing and support, magnet steel ring fixed cover is located in the rotating shaft, it is characterized in that: eccentric block is in the lower shaft end setting of rotating shaft, the rotating shaft lower shaft end has external splines, and eccentric block has internal spline, and the internal spline that the external splines of rotating shaft lower shaft end is inserted into eccentric block forms splined.The two ends of described eccentric block are provided with bearing and support.
The electric motor built-in concrete vibration bar that the utility model provides, rational in infrastructure, carry out transmission by splined between rotating shaft and the eccentric block, eccentric block and rotating shaft are part independently separately, so it is simple that the assembling of whole vibrating head just seems, replacing after the damage parts is very convenient, and eccentric block can be according to required independent replacing, to satisfy the particular demands of different operating condition simultaneously.
Description of drawings
The utility model has following accompanying drawing:
Fig. 1 is structure chart of the present utility model,
Fig. 2 is that the axial view of eccentric block among Fig. 1 is amplified.
The specific embodiment
Accompanying drawing has represented the technical solution of the utility model and embodiment, and the below further describes each details and the operating principle thereof of embodiment more by reference to the accompanying drawings.
As shown in the figure, electric motor built-in concrete vibration bar of the present utility model, comprise rod cover 6, lower cone 13, upper cover 1, stator core winding 5, magnet steel ring 4, rotating shaft 3 and eccentric block 10, lower cone 13 is threaded in the lower end of rod cover 6, upper cover 1 is threaded in the upper end of rod cover 6, rod cover 6 has the hollow circuit cylinder body structure, stator core winding 5, rotating shaft 3 and eccentric block 10 are installed in the endoporus of rod cover 6, rotating shaft 3 two ends are provided with bearing 2 and bearing 7 supports, magnet steel ring 4 fixed covers are located in the rotating shaft 3, eccentric block 10 is in the lower shaft end setting of rotating shaft 3, the two ends of eccentric block 10 are provided with bearing 9 and bearing 12 supports, the lower shaft end of rotating shaft 3 has external splines 8, and eccentric block 10 has internal spline 11, and the internal spline 11 that the external splines 8 of rotating shaft 3 lower shaft end is inserted into eccentric block 10 forms splined.
The utility model is like this work: vibrating head is inserted in the concrete, and stator core winding 5 energisings, drive shaft 3 is rotated, and rotating shaft 3 drives again eccentric block 10 and rotates, and the high speed rotating of eccentric block 10 makes vibrating head produce vibration at high speed.
