Abstract
The utility model relates to a motor revolving shaft counter bore direction identification device which comprises a base, an orientation pin and a spring. The base is composed of an upper cover and a lower cover, an ink storage chamber, an ink discharge port and a shaft penetrating hole are sequentially arranged at the center of the base, the orientation pin is installed in a cavity formed by the upper cover and the lower cover, and the top end of the orientation pin extends in the shaft penetrating hole through the spring. The orientation pin is connected with a motor revolving shaft counter bore in clamping mode to fix a motor revolving shaft, the counter bore direction is identified by ink, no positioning groove needs to be arranged on the end face of the revolving shaft, processing steps are reduced, assembly time is shortened, and manufacturing cost is saved.
Description
Technical field
The utility model belongs to technical field of motors, relates to machine shaft.
Background technology
Motor is a kind of electric rotary machine, can be mechanical energy with electric energy conversion, mainly comprises one in order to the stator winding of the electromagnet winding that produces magnetic field or distribution and rotating armature or rotor.At present, common motor is by the fixing small pulley of the counterbore in the rotating shaft, and the skew of small pulley installing hole and machine shaft counterbore easily appears in imperforation direction signs in the rotating shaft in assembling process, it is not in place that set bolt is installed, and causes motor to be in operation abnormal sound occurring and small pulley comes off.Some manufacturers leave locating slot by the machine shaft end face, guarantee that small pulley is in place.But need like this to drop into a large amount of fund, equipment and manpower.
The utility model content
For solving above-mentioned existing motor small pulley installation question, the purpose of this utility model is to provide a kind of machine shaft counterbore direction signs device, can identify fast and effectively the direction of machine shaft counterbore, has reduced procedure of processing, shorten the assembling time spent, saved manufacturing cost.
The utility model is the technical scheme that its purpose of realization is taked: a kind of machine shaft counterbore direction signs device, it is characterized in that: comprise pedestal, orienting pin and spring, described pedestal is comprised of loam cake and lower cover two parts, pedestal center ink storing chamber, lower Mo Kou and wear axis hole and once be communicated with from top to bottom, described orienting pin is installed in the chamber of pedestal, by elastic device its top is stretched into and is worn axis hole.
Elastic device is torsion spring, extension spring or stage clip.
The machine shaft top directly contacts with lower Mo Kou lower end.
Orienting pin and machine shaft counterbore are engagement connection.
The ink storing chamber bottom is the rounding cylindricality.
Lower China ink mouth is rectangle, and length is slightly less than the machine shaft external diameter, and length direction is parallel with the orienting pin center line.
Wear shaft hole diameter and be slightly larger than the machine shaft external diameter.
Orienting pin can move along its center line in chamber, and displacement stretches into the length of wearing axis hole greater than orienting pin.
The difference of wearing shaft hole diameter and machine shaft external diameter stretches into the length of wearing axis hole less than orienting pin.
The beneficial effects of the utility model:By orienting pin and machine shaft counterbore engagement connection, the fixed electrical machinery rotating shaft, the machine shaft top directly contacts with the ink port lower end, ink identifies the counterbore direction by lower China ink mouth on the machine shaft top in the ink storing chamber, small pulley installing hole and the skew of machine shaft counterbore of having avoided the common electric machine rotating shaft to cause without sign without the counterbore direction, set bolt is installed not in place, cause motor to be in operation abnormal sound occurring and small pulley comes off, also need not to guarantee that by leaving locating slot at the machine shaft end face small pulley is in place.Whole apparatus structure is simple and easy to usefulness, need not to drop into a large amount of funds, equipment and manpower, can effectively reduce procedure of processing, shortens the assembling time spent, save manufacturing cost.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is loam cake upward view of the present utility model;
Fig. 3 is lower cover top view of the present utility model.
Among the figure: 1, loam cake, 2, lower cover, 3, orienting pin, 4, spring, 5, wear axis hole, 6, lower China ink mouthful, 7, ink storing chamber, 8, the orienting pin chamber.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Such as Fig. 1, Fig. 2 and shown in Figure 3, the pedestal center has successively under ink storing chamber 7, the rectangle China ink mouthfuls 6 and wears axis hole 5, and orienting pin 3 is installed in the orienting pin chamber 8 that loam cake 1 and lower cover 2 consist of, and by spring 4 its top is stretched into and is worn axis hole 5; Lower China ink mouthful 6 length are slightly less than the machine shaft external diameter, and length direction is parallel with orienting pin 3 center lines; Wear axis hole 5 internal diameters and be slightly larger than the machine shaft external diameter; Orienting pin 3 can move along its center line in chamber, and displacement stretches into the length of wearing axis hole 5 greater than orienting pin 3; Orienting pin 3 stretch into wear axis hole 5 length greater than the difference of wearing axis hole 5 internal diameters and machine shaft external diameter.
During use, orienting pin 3 is placed in the chamber after loading onto spring 4, because effect orienting pin 3 tops of spring 4 are stretched into and worn axis hole 5, pedestal loam cake 1 and lower cover 2 are bolted, and puts into the ink storage material such as sponge, cotton and drip ink in ink storing chamber 7.On machine shaft and rotation, make orienting pin 3 fall into the rotating shaft counterbore base sleeve, machine shaft top and lower China ink mouthfuls 6 directly contact, determine that rotating shaft can't be rotated after, press the ink storage material, make ink stay sign by lower black mouth 6 at the rotating shaft end face.When small pulley is installed, as long as make the installing hole of small pulley aim at the tag line of machine shaft, just can aligning carry out bolt and fix.
