Description

Technical Field

[0001] The present invention relates to the field of motors, and more particularly to a servo motor. Background Art

[0002] The concept of servo motor generally refers to an adjustable motor with servo characteristics and especially without brushes. This motor is widely used. The output shaft of the motor is connected to the power output part, and the power is output through the transmission of the output shaft of the motor and the power output part. When the connection between the output shaft of the motor and the power output part fails, the power cannot be transmitted. The existing private servo motor cannot be connected to the power output part in two ways to ensure the stable output of the servo motor power. Summary of the invention

[0003] In order to improve the deficiencies of the prior art, the present invention provides a servo motor that can be connected to a power output part in two ways to ensure stable output of the servo motor power.

[0004] The technical solution adopted by the present invention to solve its technical problem is:

[0005] A servo motor comprises a body and a spline shaft rotatably connected to the body, a sliding sleeve is slidably connected to the spline shaft, and a plurality of engaging rods are circumferentially arranged on the sliding sleeve.

[0006] Furthermore, a spring plate is fixedly connected to the sliding sleeve, a plurality of springs are fixedly connected to the spring plate, another spring plate is fixedly connected to the other end of the plurality of springs, and an end sleeve for limiting the rotation of the corresponding spring plate is fixedly connected to the fuselage.

[0007] Furthermore, a support plate is fixedly connected to the fuselage, a travel sensor is fixedly connected to the support plate, and a counting sensor is fixedly connected to the travel sensor.

[0008] Furthermore, an arc block is fixedly connected to the stroke sensor.

[0009] Furthermore, the minimum distance between the arc surface of the arc block and the axis of the spline shaft is smaller than the maximum distance between the plurality of engaging rods and the axis of the spline shaft.

[0010] The beneficial effects of a servo motor of the present invention are: it can be connected to a power output part in two ways to ensure stable output of the servo motor power; it can also accurately control the number of revolutions of the servo motor output shaft by counting the number of rotations of the motor output shaft; and it can also cool the servo motor by exchanging heat with the servo motor through coolant.

DETAILED DESCRIPTION

[0021] refer to Figure 1 , 4 and 5, detailing an embodiment of stabilizing the power output of the servo motor:

[0022] A servo motor comprises a body 11 and a spline shaft 14 rotatably connected to the body 11, the spline shaft 14 being the output shaft of the servo motor, the spline shaft 14 outputting the motor power through its own concave and convex, a sleeve 31 being slidably connected to the spline shaft 14, a plurality of interlocking rods 32 being circumferentially arranged on the sleeve 31, the plurality of interlocking rods 32 being slidably inserted into the parts for outputting the motor power, so that when the spline shaft 14 rotates, the power can be output synchronously through the sleeve 31 and the plurality of interlocking rods 32 on the sleeve 31 through transmission through its own keyway, and the power output can be effectively prevented when the spline shaft 14 and the parts for outputting the power can be output through the sleeve 31 and the plurality of interlocking rods 32, so that the power transmission can be realized, and the power output can be performed in two ways, thereby ensuring the stability of the motor power output.

[0023] refer to Figure 1 , 2 3, detailed description of the embodiment of pushing the sliding sleeve 31 to drive the multiple engaging rods 32 to be inserted into the parts of the motor power transmission:

[0024] The sliding sleeve 31 is fixedly connected with a spring plate 21, and a plurality of springs 22 are fixedly connected with the spring plate 21. The other end of the plurality of springs 22 is fixedly connected with another spring plate 21. An end sleeve 13 for limiting the rotation of the corresponding spring plate 21 is fixedly connected to the fuselage 11. Under the push of the spring force of the plurality of springs 22, the spring plate 21 fixedly connected to the sliding sleeve 31 drives the sliding sleeve 31 to slide, and the sliding sleeve 31 drives the plurality of engaging rods 32 to slide onto the parts of the motor power output, thereby ensuring that in the absence of external force, the sliding sleeve 31 is always in contact with the parts of the motor power output, ensuring that the plurality of engaging rods 32 are inserted into the parts of the motor power output to output power.

[0025] refer to Figure 1 , 2 , 4 and 6, detail embodiments of monitoring the number of rotations of the spline shaft 14:

[0026] The fuselage 11 is fixedly connected with a support plate 15, and a stroke sensor 41 is fixedly connected with the support plate 15. The stroke sensor 41 is fixedly connected with a counting sensor 43. The counting sensor 43 can be connected with the controller, so that when power is turned on, the counting sensor 43 can monitor how many times the stroke sensor 41 is pushed, and when the spline shaft 14 rotates, it drives the sliding sleeve 31 to rotate, and the sliding sleeve 31 drives the multiple interlocking rods 32 to rotate. When the multiple interlocking rods 32 rotate and rotate to contact with the stroke sensor 41, the stroke sensor 41 is squeezed, so that the stroke sensor 41 can detect how many times it is squeezed, and the counting sensor 43 monitors the number of detections of the stroke sensor 41 to measure the number of rotations of the spline shaft 14, so as to fully control the number of rotations of the spline shaft 14 of the servo motor, thereby accurately controlling the number of rotations of the spline shaft 14.

[0027] refer to Figure 1 and 6 , detailed description of an embodiment of ensuring that the plurality of engaging rods 32 rotate to push the stroke sensor 41:

[0028] The stroke sensor 41 is fixedly connected with an arc block 42, so that when the multiple interlocking rods 32 rotate, the multiple interlocking rods 32 gradually push the arc block 42, thereby achieving the extrusion of the stroke sensor 41, and the arc surface of the arc block 42 can contact and guide the outer wall of the interlocking rod 32, so that the interlocking rod 32 squeezes the arc block 42 more smoothly, thereby achieving the accurate detection of the number of turns of the spline shaft 14 by the stroke sensor 41. The minimum distance between the arc surface of the arc block 42 and the axis of the spline shaft 14 is less than the maximum distance between the multiple interlocking rods 32 and the axis of the spline shaft 14, thereby ensuring that the multiple interlocking rods 32 can push the arc block 42 to slide when rotating, thereby achieving the counting of the number of turns of the spline shaft 14.

[0029] refer to Figure 1 , 4 and 7, detailed description of the embodiment of the regular counting sensor 43 line body:

[0030] The support plate 15 is fixedly connected with an auxiliary frame 16 for supporting the wire of the counting sensor 43 , so that the wire of the counting sensor 43 can be regulated by the auxiliary frame 16 to prevent the wire from being entangled on the spline shaft 14 .

[0031] refer to Figure 1 , detailed description of the embodiment of connecting the servo motor line body:

[0032] The fuselage 11 is fixedly connected with a junction box 12, and the junction box 12 is fixedly connected with a regular frame supporting its own wire body and the wire body of the counting sensor 43, so as to realize the regularity of the wire body, ensure the regular arrangement of the wire body, and ensure the safe use of the servo motor.

[0033] refer to Figure 1 and 8 , detailed description of the embodiment of cooling the servo motor:

[0034] The cooling box 51 is fixedly connected to the fuselage 11, and two connecting pipes 52 are detachably connected to the cooling box 51, so that the cooling box 51 can be connected to the cooling liquid supply device through the two connecting pipes 52, so that the cooling liquid supply device can circulate the cooling liquid in the cooling box 51 through the two connecting pipes 52, thereby cooling the servo motor. The cooling box 51 is provided with a straight opening that allows the terminal box 12 to pass through, so that the cooling box 51 can be installed on the fuselage 11, thereby ensuring that the cooling box 51 fully cools the servo motor, and coolant can also be added to the cooling box 51, and the connection between the two connecting pipes 52 is sealed to achieve the storage of the cooling liquid in the cooling box 51, thereby achieving the cooling of the servo motor by the cooling box 51.

[0035] refer to Figure 1 and 4 , detailed description of the embodiment of the regular line body:

[0036] The auxiliary frame 16 is processed with an opening so as to limit the position of the wire body, and the wire body can also be removed through the opening to achieve the regularity of the wire body.
