Description

Technical Field

[0001] The utility model relates to the technical field of flanges, in particular to a flange for a stepping motor. Background Art

[0002] A stepper motor is an induction motor. Its working principle is based on the principle of electromagnetism. It achieves precise control of the motor's rotation angle and speed by controlling the frequency and number of electrical pulse signals. Every time a pulse signal is input, the stepper motor's rotor rotates a fixed angle, called the "step angle". The stepper motor flange is an interface component used to connect the stepper motor and the mechanical device. It can transmit the stepper motor's rotation speed to the mechanical device to achieve precise position control.

[0003] After searching, the Chinese patent with application number CN209354547U discloses a motor flange. When the inner diameter of the flange is too large, the flange will shake on the motor shaft. When the inner diameter of the flange is too small, it is not conducive to the installation and removal of the flange. Since the size of the inner diameter of the flange directly affects the fit with the motor shaft, the machining accuracy of the inner diameter of the flange is very high, and the keyway needs to be high-precision, which requires the use of wire cutting technology, resulting in slow processing speed and increased costs, resulting in high keyway processing costs, and the transmission torque has a great impact on the keyway. The stress of the groove is shear stress, and the transmitted torque is small. The torque transmitted by the flange is insufficient, so the shape of the inner circle of the flange is C-shaped. The function of the threaded holes on the flange is to fasten the rotor core and transmit the torque, so that the torque on the rotor core is transmitted to the flange; the positioning holes can perform circumferential positioning of the rotor core; and the function of the C-shaped inner circle is to transmit the torque transmitted by the rotor core to the motor shaft. The flange adopts a C-shaped inner circle to convert the shear stress generated by the torque into extrusion stress, thereby increasing the transmitted torque; and the C-shaped inner circle of the flange has low precision requirements, which reduces processing costs.

[0004] When the above-mentioned flange is in use, since the position of the holes in the internal flange is fixed, if the flange is installed on the motor first, when the other side is connected to other interfaces, the position of the mounting holes in the interface may deviate, so that the flange on the motor needs to be removed and reinstalled, which can easily lead to a more troublesome installation process and low installation efficiency. In addition, it is not convenient to align the mounting holes in the flange with the mounting holes in other interfaces, which reduces the installation accuracy. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] As attached Figure 1-6 As shown, the utility model provides an embodiment: a flange for a stepper motor, comprising a mounting ring 1, and an adjustment mechanism is arranged outside the mounting ring 1;

[0033] The adjusting mechanism comprises a connecting ring 2, which is fixedly connected to the outside of the mounting ring 1; a sliding groove 3 is provided inside the connecting ring 2; a plurality of connecting rods 4 are fixedly connected to the outside of the sliding groove 3; an outer ring 5 is fixedly connected to the other end of the plurality of connecting rods 4; a stabilizing ring 6 is slidably connected to the inside of the sliding groove 3; an adjusting ring 7 is fixedly connected to the outside of the stabilizing ring 6; a plurality of mounting holes 8 are provided on the outside of the adjusting ring 7; a plurality of hole grooves 9 are provided on the upper surface of the outer ring 5; a fixing block 10 is fixedly connected to the upper surface of the adjusting ring 7; a threaded sleeve 11 is fixedly connected to the middle part of the fixing block 10; a threaded column 12 is threadedly connected to the inner part of the threaded sleeve 11; the sliding groove 3 is used for the sliding connection of the stabilizing ring 6; the adjusting ring 7 is convenient for driving the position of the hole groove 9 to move; and the threaded sleeve 11 is convenient for the threaded connection of the threaded column 12.

[0034] As attached Figure 6 As shown, multiple silencer springs 13 and multiple protective shells 14 are fixedly connected to both sides of the connecting ring 2. The silencer springs 13 are arranged inside the protective shell 14. The multiple silencer springs 13 are distributed in a ring shape. The other end of the silencer spring 13 is fixedly connected to a protrusion 15. The protrusion 15 is slidably connected to the inside of the protective shell 14. One side of the multiple protrusions 15 is fixedly connected to a silencer plate 16. The silencer plate 16 is made of stainless steel. One side of the silencer plate 16 is provided with multiple silencer pads 17. The silencer pads 17 are made of mineral wool. The protective shell 14 facilitates the limiting protection of the silencer spring 13, and the protrusion 15 facilitates the sliding of the protective shell 14.

[0035] As attached Figure 2 As shown, a plurality of elastic balls 18 are arranged on the lower surface of the outer ring 5, and the plurality of elastic balls 18 are distributed in a ring shape, so that the vibration force can be squeezed to the elastic balls 18, thereby producing a sound-absorbing effect.

[0036] As attached Figure 1 As shown, an elastic strip 19 is provided on the upper surface of the outer ring 5, and the plurality of elastic balls 18 and the elastic strip 19 are all made of rubber material, which facilitates rebound under pressure, thereby achieving noise reduction.

[0037] Working principle: After one side of the flange is installed on the motor, when the other side needs to be connected to the connecting piece and the holes are difficult to align, twist the threaded column 12 to make the threaded column 12 disengage from the inside of the threaded sleeve 11, and then release the limit fixation of the fixing block 10, and then rotate the adjusting ring 7 to make the adjusting ring 7 drive the multiple mounting holes 8 to revolve, and at the same time, the adjusting ring 7 drives the stabilizing ring 6 to slide inside the slide groove 3, and the other side slides inside the outer ring 5, which is conducive to adjusting the position of the mounting hole 8 on the adjusting ring 7. After adjustment, screw the threaded column 12 back into the threaded sleeve 11 to facilitate the other end of the threaded column 12 to be inserted into the inside of the hole groove 9, thereby fixing the position of the fixing block 10 and facilitating the fixing of the position of the mounting hole 8;

[0038] When the power output by the motor drives the flange to vibrate, the vibration force will squeeze the silencer pad 17, and the silencer pad 17 will collide with the connected object, thereby producing a first layer of silencer effect. Then, when the silencer pad 17 is pressed down, it will squeeze the silencer plate 16, so that the silencer plate 16 pushes the protrusion 15 under the action of multiple silencer springs 13, so that the protrusion 15 slides inside the protective shell 14, thereby producing a secondary silencer effect on the vibration force. Then, at the same time, the elastic strip 19 facilitates the third layer of silencer on one side of the flange, and the multiple elastic balls 18 facilitate the third layer of silencer on the other side, which is conducive to reducing the phenomenon of noise pollution in the working environment.
