Abstract
The utility model provides a main shaft end guide locking device for a large-scale power concentrator, comprising a thread hole I which is matched with the main shaft end thread, a guide locking body, a tool withdrawal groove, amd two thread holes II which are matched with the fastening bolts. The guide locking body is the combination of a cylinder and a circular platform. The upper part of the body is in a cylinder shape, and the lower part is in a circular platform shape. The upper end face of the cylinder of the guide locking body is provided with the thread hole I which is matched with the main shaft end thread, and the lower end face of the circular platform is provided with the two thread holes II which are matched with the fastening bolts. The tool withdrawal groove is design to satisfy the process requirement of the guidance locking body, and is arranged between the thread hole I and the thread hole II.
Description
Technical field
The utility model relates to a kind of locking device of powder concentrator, especially a kind of guiding locking device of large-scale powder concentrator main-axis end.
Background technique
Along with the propelling of large-scale new dry process line, the maximization of grinding equipment is further advanced, and the maximization of classifying equipoment has become inevitable in the grinding equipment.When powder concentrator maximized, its whole processing, installation, transportation, debugging, equipment investment etc. had become a common attention point, and the fit of equipment investment cost wherein, main shaft and rotor is the most important.In order to save cost, make things convenient for Installation and Debugging, the large-scale assembling of selecting powder to equip main shaft and rotor adopts segmentation to install usually.
The locking of existing powder concentrator main shaft and coupling band adopts round nut to add the mode of lock washer usually, be difficult for when this mode is not only installed installing, and the collision in the installation process also can cause the damage of main shaft portion screw thread.Be difficult for guide-localization when especially the whole main shaft portion of main shaft and coupling band formation and cage rotor assemble.
The model utility content
Technical problem to be solved in the utility model is, at the deficiencies in the prior art part, a kind of large-scale powder concentrator main-axis end guiding locking device is provided, this device has not only solved the locking problem of main-axis end in powder concentrator maximization and other equipment, and easy for installation, in main shaft portion and cage rotor assembly process, can realize the positioning and guiding effect of certain limit simultaneously.
The technical scheme in the invention for solving the technical problem: comprise tapped hole I, guiding locking body, tool withdrawal groove, two tapped hole II that match with clamping bolt with the main-axis end threads engaged.
Guiding locking body is the assemblying body of cylinder and round platform, and its top is cylindrical, and the bottom is frustoconic shape.
Guiding locking body cylinder upper-end surface has the tapped hole I with the main-axis end threads engaged, and its round platform lower end surface has two tapped hole II that match with clamping bolt.
Tool withdrawal groove then is for the requirement of satisfying guiding locking bulk process designs, and places between tapped hole I and the tapped hole II.
After coupling band that cooperates with the powder concentrator main shaft and powder concentrator spindle mounted finish, screw on guiding locking body at main-axis end screw thread place, after treating guiding locking body fix in position, two clamping bolts are tightened from guiding locking body below by tapped hole II, bolt is contacted with the main-axis end end face, thereby further realize locking.
At this moment just can lift whole main shaft portion and cage rotor assembles, because guiding locking body top is cylindrical, and the upper-end surface diameter equates with the cage rotor internal diameter, can realize location, the leading role of certain limit in assembly process, helps the assembling of complete machine.
The beneficial effects of the utility model are: solved the locking problem of main-axis end in powder concentrator maximization and other equipment, and also easy for installation, in powder concentrator main shaft portion and cage rotor assembly process, realize the positioning and guiding effect of certain limit simultaneously.
Description of drawings
Fig. 1 is a plan view of the present utility model;
Fig. 2 is a plan view of the present utility model;
Among the figure: 1 is that tapped hole I, 2 is that guiding locking body, 3 is that tool withdrawal groove, 4 is tapped hole II.
Specific embodiment
Present embodiment comprises and the tapped hole I1 of main-axis end threads engaged, guiding locking body 2, tool withdrawal groove 3, two tapped hole II4 that match with clamping bolt.
Guiding locking body 2 is assemblying bodys of cylinder and round platform, and its top is cylindrical, and the bottom is frustoconic shape.
Guiding locking body 2 cylinder upper-end surfaces have the tapped hole I1 with the main-axis end threads engaged, and its round platform lower end surface has two tapped hole II4 that match with clamping bolt.
3 of tool withdrawal grooves are for the requirement of satisfying guiding locking bulk process designs, and place between tapped hole I1 and the tapped hole II4.
After coupling band that cooperates with the powder concentrator main shaft and powder concentrator spindle mounted finish, screw on guiding locking body 2 at main-axis end screw thread place, after treating guiding locking body 2 fix in position, two clamping bolts are tightened from guiding locking body 2 belows by tapped hole II4, bolt is contacted with the main-axis end end face, thereby further realize locking.
At this moment just can lift whole main shaft portion and cage rotor assembles, because guiding locking body 2 tops are cylindrical, and the upper-end surface diameter equates with the cage rotor internal diameter, can realize location, the leading role of certain limit in assembly process, helps the assembling of complete machine.
So not only solved the locking problem of main-axis end in powder concentrator maximization and other equipment, and easy for installation, in powder concentrator main shaft portion and cage rotor assembly process, realize the positioning and guiding effect of certain limit simultaneously.
