Abstract
The utility model relates to an excircle grinding head for a large sleeping car. The excircle grinding head comprises a connecting sleeve in which a main shaft is positioned. The excircle grinding head is characterized in that an end cover is positioned at one end of the connecting sleeve, and an electric motor is positioned at the other end of the connecting sleeve; one end of the main shaft is connected with the power output end of the electric motor, and the other end of the main shaft stretches out of the end cover; and a polish disc is positioned at the end part of the main shaft. The main shaft is fixed with the connecting sleeve by a bearing. The polish disc is fixed on the main shaft by round nuts and spacers. The electric motor is positioned on a fixed board. Compared with the prior art, the excircle grinding head for the large sleeping car has the advantages that: 1. the installation is convenient, all the general sleeping car can be installed without professional installation personnel, and the application is wide; 2. the structure is simple and practical and does not need high maintenance cost; 3. the polish disc is easy to replace, the general staff can replace the polish disc, and dynamic balance does not need to be adjusted like the replacement of a sand wheel in the excircle grinding head, therefore, time and labor are saved; and 4. the operation is simple, and the general lathe operators can independently operate without training.
Description
Technical field
The utility model relates to a kind of cylindrical bistrique that is used for large-scale sleeping carriage, belongs to field of mechanical technique.
Background technology
Along with the high speed development of China's mechanical industry, country advocates green energy resource energetically, and wind-power electricity generation is the industry that state key is supported, and is more and more to the demand of wind-powered electricity generation major part main shaft, along with MW class constantly strengthens.Along with diameter and all significantly increasings of weight of main shaft, the difficulty of processing of bearing installed surface is increasing, also has been difficult to reach requirement of client as depending the lathe Vehicle Processing in the past alone.Little and in light weight can also being placed on the peripheral milling of low in the past megawatt hour main shaft diameter ground, and needs the secondary clamping, wastes time and energy, and still can satisfy customer requirement substantially, the present big Heavy Weight of main shaft diameter, and general peripheral milling outside dimension and load-bearing all can not be processed.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of cylindrical bistrique that is used for large-scale sleeping carriage easy for installation, simple to operate is provided.
According to the technical scheme that the utility model provides, the described cylindrical bistrique that is used for large-scale sleeping carriage comprises adapter sleeve, and main shaft is installed in adapter sleeve, it is characterized in that: the end at described adapter sleeve is installed end cap, at the other end of adapter sleeve motor is installed; One end of described main shaft is connected with the clutch end of motor, and the other end of main shaft stretches out end cap, and installation is dumped in the end.
Utilize bearing fixing between described main shaft and the adapter sleeve.
Described dumping utilizes round nut and spacers on main shaft.
Described motor is installed on the fixed head.
The utility model is compared with existing technology and is had the following advantages:
1, easy for installation, general sleeping carriage can both be installed, and does not need the installation personnel of specialty, and use is extensive;
2, simple and practical, do not need high maintenance cost;
3, dump replacing simply, general employee can both oneself change, and does not need picture peripheral milling replacing emery wheel to calibrate dynamic balancing, and is time saving and energy saving;
4, simple to operate, general latheman need not train just can independent operation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: the cylindrical bistrique that is used for large-scale sleeping carriage comprises round nut 1, pad 2, specially dumps 3, end cap 4, main shaft 5, motor 6, fixed head 7, adapter sleeve 8, bearing 9 etc.
The utility model comprises adapter sleeve 8, at an end of adapter sleeve 8 end cap 4 is installed, and the other end is installed motor 6, and main shaft 5 is installed in adapter sleeve 8; Utilize bearing 9 fixing between described main shaft 5 and the adapter sleeve 8; One end of main shaft 5 is connected with the clutch end of motor 6, and the other end of main shaft 5 stretches out end cap 4, and installation dumps 3 in the end;
Dump and 3 utilize round nut 1 and pad 2 to be fixed on the main shaft 5;
Described motor 6 is installed on the fixed head 7.
The utility model is dumped and 3 is utilized two pads 2 and round nut 1 to fix on main shaft 5 in use, can follow main shaft 5 rotations; Fixed head 7 is installed to the sleeping carriage knife rest tightens, utilize the sleeping carriage X-axis just can regulate the amount of feeding, utilize lathe Z axle just can regulate to need the length of finish grinding,, can satisfy the requirement of main shaft best bright finish owing to having adopted high-speed bearing, motor 6 and specially having dumped 3.
