Abstract
A groove broacher for a direct-current motor commutator relates to a groove broacher for grooves of mica plates in a direct-current motor commutator, and comprises a rotor support, a motor disposed on a cutting rack, a cutting tool connected with the motor, a vertical adjusting controller and a longitudinal adjusting controller, wherein the cutting rack is controlled to move vertically by the aid of the vertical adjusting controller, and controlled to move longitudinally by the aid of the longitudinal adjusting controller. The groove broacher as a special maintenance tool for direct-current motors guarantees maintenance quality and timeliness of the direct-current motors, original manual operation is changed to mechanical operation, physical labor is greatly reduced, and market gaps are filled.
Description
Technical field
The utility model relates to the commutator prosthetic device of direct current machine, specially refers to the groove broacher of insulating concrete mica plate groove in the commutator.
Background technology
In DC motor, commutator matches with brush, external dc power supply can be converted to the alternating current in the armature coil, makes the direction of electromagnetic torque invariable.The cylinder that commutator is made up of many commutator segments is used mica-sheet insulation between the commutator segment, commutation.DC motor in use, commutator segment and brush constantly rub repeatedly, commutator segment will be worn, and must process again.Commutator segment after the processing is recessed down, and mica sheet then outwards protrudes, and commutator just can not be worked.The mica sheet that must will outwards protrude is removed, and forms groove, commutator ability operate as normal, and the electric current commutation of direct current machine could continue to carry out well.But for a long time, the maintenance of this type of direct current machine maintenance operation can only rely on manually removes kerve with saw blade, and operating efficiency is low, and labour intensity is big, and maintenance time is longer, and quality fluctuation is bigger, and really effort is time-consuming again, is difficult to satisfy in time produce needs.
The utility model content
The technical problems to be solved in the utility model is to overcome deficiency of the prior art, proposes a kind of DC motor commutator groove broacher, discarded manual work, adopt mechanization and automated job, to improve operating efficiency, it is big to reduce labour intensity, reduce quality fluctuation, satisfy in time and produce needs.
The utility model is to realize by following technical measures.A kind of DC motor commutator groove broacher comprises rotor field spider, also comprises the motor that is arranged on the cutting rack, the cutting tool that is connected with motor, the up-down adjustment controller that the control cutting rack moves up and down, the front and back conditioning controller that the control cutting rack moves forward and backward.
Described motor is a pneumatic motor.
Described up-down adjustment controller comprises backstay handle and positioning tooth wheels.
Described front and back conditioning controller comprises motor, transmission mechanism and walking guide rail.
The utility model can reduce the trust maintenance cost after adopting abovementioned technology, reduces the spare unit buying, has realized the mechanization of electrical machmary maintenance industry DC motor commutator insulating concrete mica plate kerve.Shortened the direct current machine maintenance time, improved operating efficiency, alleviated labour intensity, eliminated the uneven quality of artificial kerve and cannot say for sure to demonstrate,prove, this technology is not only simple in structure, and low cost of manufacture is used also very convenient.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model embodiment.
Among the figure: 1 is rotor field spider, and 2 is cutting rack, and 3 is pneumatic motor, and 4 is cutting tool, and 5 are up-down adjustment control, and 5-1 is the backstay handle, and 5-2 is the positioning tooth wheels, and 6 is the front and back conditioning controller, and motor 6-1, transmission mechanism are 6-2, and the walking guide rail is 6-3.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, a kind of DC motor commutator groove broacher, comprise rotor field spider 1, also comprise the pneumatic motor 3 that is arranged on the cutting rack 2, the cutting tool 4 that is connected with pneumatic motor 3, the up-down adjustment controller 5 that control cutting rack 2 moves up and down, the front and back conditioning controller 6 that control cutting rack 2 moves forward and backward.
Up-down adjustment controller 5 comprises backstay handle 5-1 and positioning tooth wheels 5-2.
Front and back conditioning controller 6 comprises motor 6-1, transmission mechanism 6-2 and walking guide rail 6-2.
When the d.c. motor commutator of needs maintenance after machined into, be put on the rotor field spider 1 and the mica film trap that will need to cut places the upper end of vertical direction.Utilize the position of the positioning tooth wheels 5-2 adjustment cutting rack 2 in the up-down adjustment controller 5, make cutting tool 4 aim at mica cutting tool 4 grooves that need cutting, and fixed with backstay handle 5-1.Start pneumatic motor 3 then, make cutting tool 4 begin to cut mica cutting tool 4 grooves.Meanwhile, the motor 6-1 before and after starting in the conditioning controller 6 moves cutting rack 2 by transmission mechanism 6-2 and walking guide rail 6-2 in the past backward gradually, and pneumatic motor 3 moves synchronously with cutting tool 4 in the past backward gradually.This moment, cutting tool 4 one side were carried out the degree of depth cutting of mica film trap, and cutting tool 4 moves in the past backward on the other hand, finished up to a mica film trap cutting.Then commutator is turned to next groove, proceed cutting operation.
Above-described only is preferred implementation of the present utility model.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection range of the present utility model.
