Abstract
The utility model relates to a grinding device of a direct-current motor carbon brush. The grinding device of the direct-current motor carbon brush comprises a driving motor, a first belt pulley, a second belt pulley, a transmission shaft and a bearing, wherein the driving motor, the first belt pulley, the second belt pulley, the transmission shaft and the bearing are arranged on a rack. The first belt pulley is installed on an output shaft of the driving motor and connected with the second belt pulley through a triangular belt, the transmission shaft is installed on the rack through the bearing, the second belt pulley is installed at one end of the transmission shaft, the other end of the transmission shaft extends out of the rack, and a grinding head is arranged at the other end of the transmission shaft. The motor is used for providing motive power, the grinding head is driven to rotate through the triangular belt, the working state of the carbon brush is simulated, and the carbon brush needed by the whole motor is grinded to form a cambered surface in a one-time mode. Besides the structure is simple, using method is simple and convenient to use and easy to master.
Description
Technical field
The utility model belongs to direct current generator manufacturing technology field, relates to a kind of milling apparatus, especially a kind of direct current generator carbon brush milling apparatus.
Background technology
At present, direct current generator grinds the carbon brush cambered surface, all is to adopt after the motor assembling fine sandpaper is placed between commutator and the carbon brush, commutator is close at the sand paper back side, manually with the tension of sand paper two ends, motion sand milling carbon brush makes the identical method of carbon brush cambered surface and commutator exterior arc surface repeatedly.The work efficiency of doing like this is very poor, and carbon dust can enter motor internal, is difficult to clean out.Some producers adopt the method that mills out cambered surface on CNC milling machine, and work efficiency is not high yet, and need take equipment.Other has some producers directly to buy the carbon brush of band cambered surface, because of radian differs, can increase the buying difficulty, also can increase manufacturing cost simultaneously.
The utility model content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, a kind of direct current generator carbon brush milling apparatus is provided, this equipment can utilize motor that power is provided, drive the bistrique rotation by the V-belt, simulation carbon brush duty, disposable whole the required carbon brush of motor ground out cambered surface, and simple in structure, the easy easy grasp of using method.
The purpose of this utility model solves by the following technical programs:
This direct current generator carbon brush milling apparatus comprises the drive motors, first belt pulley, second belt pulley, power transmission shaft and the bearing that are arranged on the frame; Described first belt pulley is installed on the drive motors output shaft, and is connected with second belt pulley by the V-belt; Described power transmission shaft is installed on the frame by bearing, and described second belt pulley is installed in an end of power transmission shaft; The other end of power transmission shaft stretches out frame bistrique is installed.
The other end of above-mentioned power transmission shaft also is equipped with brush holder dish seat near the bearing place.
Above-mentioned bistrique is a cylindrical shell, fixedlys connected with power transmission shaft is coaxial, and the urceolus face of bistrique is a working face.
Direct current generator carbon brush milling apparatus of the present utility model has been broken through traditional thinking, and craft originally or lathe monomer method for processing go to live simulation processing, has better guaranteed the goodness of fit of cambered surface, and the colleague who improves the carbon brush Grinding Quality raises the efficiency.
Description of drawings
Fig. 1 is thermometric junction box structure figure of the present utility model;
Wherein: 1 is first belt pulley; 2 is the V-belt; 3 is second belt pulley; 4 is power transmission shaft; 5 is bearing; 6 is brush holder dish seat; 7 is bistrique; 8 is drive motors.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Referring to Fig. 1, this direct current generator carbon brush milling apparatus comprises drive motors 8, first belt pulley 1, second belt pulley 3, power transmission shaft 4 and the bearing 5 that is arranged on the frame.Wherein first belt pulley 1 is installed on drive motors 8 output shafts, and is connected with second belt pulley 3 by V-belt 2; Power transmission shaft 4 is installed on the frame by bearing, and second belt pulley 3 is installed in an end of power transmission shaft 4; The other end of power transmission shaft 4 stretches out frame bistrique 7 is installed.And the other end of power transmission shaft 4 also is equipped with in order to the fixing brush holder dish seat 6 of brush holder near bearing 5 places.As shown in the figure, brush holder dish seat 6 is discoid, and fixed cover is located on the power transmission shaft 4.Described bistrique 7 is a cylindrical shell, and with power transmission shaft 4 coaxial fixedlying connected, the urceolus face of bistrique 7 is a working face.
Brush holder dish seat 6 of the present utility model and bistrique 7 can be adjusted at any time according to the model of brush holder, during use, at first will select the brush holder dish seat 6 and the bistrique 7 of ready respective model for use, and brush holder dish seat 6 and bistrique 7 be filled to the tram, then with the brush holder overall fixed that assembles on the brush holder dish 6 of milling apparatus, starting device mixes up the various parameters that adapt to this commutator model, begins to grind.
