Description

Technical Field

[0001] This application relates to the field of servo motor technology, and more specifically, to a servo motor output shaft angle positioning fixture. Background Technology

[0002] A servo motor is a position (angle) servo actuator suitable for control systems that require continuous angle changes and the ability to maintain those angles. It is widely used in drones, robots, and various automated devices.

[0003] When a servo motor leaves the factory, it needs to be set to an initial angle (i.e., the zero-position angle). This initial angle setting is an important step, as it ensures that the servo motor can maintain a specific position without any external control signal adjustment.

[0004] When setting the initial angle of a servo motor, the operator needs to manually rotate the output shaft of the servo motor to the initial angle. During this process, it is necessary to measure whether the output shaft has rotated to the initial angle multiple times, which results in low efficiency in setting the target angle.

[0005] Therefore, how to improve the efficiency of setting the target angle of the servo motor is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the purpose of this application is to provide a servo motor output shaft angle positioning fixture to improve the efficiency of setting the target angle of the servo motor.

[0007] To achieve the above objectives, this application provides the following technical solution:

[0008] The first aspect of this application provides a servo motor output shaft angle positioning fixture for assisting the servo motor in positioning the target angle of the servo motor output shaft, including:

[0009] The tooling body has a positioning part and an output shaft fixing part for fixing to the output shaft of the servo motor, and the positioning part has a strip groove.

[0010] An angle positioning assembly includes a fastener and an angle positioning component. The angle positioning component has a fastening screw hole. The screw portion of the fastener passes through the slot and is threaded into the fastening screw hole. The nut of the fastener and the angle positioning component are respectively clamped on both sides of the positioning part. The side of the positioning part facing the nut of the fastener is provided with a first friction texture. A washer is fitted on the fastener. The washer is provided with a second friction texture that mates with the first friction texture. The nut of the fastener presses the washer onto the positioning part and is fixed to the servo output shaft at the output shaft fixing part. When the servo output shaft rotates to the target angle, the angle positioning component and the servo form a limit.

[0011] In one possible implementation, the angular positioning element is a cylindrical structure.

[0012] In one possible implementation, the positioning part and the output shaft fixing part are connected by a connecting part;

[0013] The positioning part and the output shaft fixing part extend from the connecting part to different sides, respectively.

[0014] In one possible implementation, the extending direction of the positioning part is parallel to the extending direction of the output shaft fixing part, and both are perpendicular to the extending direction of the connecting part.

[0015] In one possible implementation, the extension direction of the strip groove is perpendicular to the extension direction of the connecting portion.

[0016] In one possible implementation, the positioning part has multiple fixing holes, and the angle positioning component can be selectively fixed to one of the fixing holes.

[0017] In one possible implementation, the output shaft fixing part has an output shaft mounting hole for cooperating with the servo output shaft and a clamping groove that passes through the output shaft fixing part and communicates with the output shaft mounting hole;

[0018] The clamping groove divides the fixed portion of the output shaft into two clamping arms;

[0019] The servo output shaft angle positioning fixture also includes a clamping assembly for clamping the two clamping arms.

[0020] In one possible implementation, the clamping assembly includes:

[0021] The connecting screw and the connecting nut are provided, and both clamping arms are provided with clamping holes for the connecting screw to pass through;

[0022] A quick-release control component is provided, which has a cam portion. One end of the connecting screw is eccentrically hinged to the quick-release control component. The quick-release control component and the connecting nut are respectively disposed on both sides of the output shaft fixing portion.

[0023] In one possible implementation, the tooling body is made of plastic;

[0024] And / or,

[0025] The angle positioning component is made of metal.

[0026] In one possible implementation, when the servo output shaft rotates to the target angle, the angle positioning component forms a limit with the upper surface of the servo.

[0027] The servo output shaft angle positioning fixture provided in this application, when used for setting the target angle of the servo output shaft, requires fixing the output shaft fixing part of the fixture body to the servo output shaft, so that the servo output shaft angle positioning fixture rotates synchronously with the servo output shaft when it rotates. When rotating in the corresponding direction until the angle positioning component and the servo form a limit, that is, when the angle positioning component and the servo form a limit, the servo output shaft can no longer rotate in that direction, and the angle of the servo output shaft at this time is the target angle to be set. With the servo output shaft angle positioning fixture provided in this application, it is not necessary to measure the servo output shaft multiple times when setting the target angle, thus improving the efficiency of setting the servo target angle.

[0041] The core of this application is to provide a servo motor output shaft angle positioning fixture to improve the efficiency of setting the target angle of the servo motor.

[0042] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the application as described in the claims. Additionally, the complete composition represented in the embodiments below is not limited to what is necessary as the solution to the application described in the claims. It should be noted that, for ease of description, only the parts relevant to the application are shown in the drawings. Unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0043] like Figures 1-3 As shown in the embodiment of this application, the servo output shaft angle positioning fixture 200 is used to assist the servo 100 in positioning the target angle of the servo output shaft 110. The target angle can be the initial angle that needs to be set when the servo leaves the factory, or it can be other angles that need to be positioned.

[0044] The servo motor output shaft angle positioning fixture 200 includes a fixture body 210 and an angle positioning assembly 230. The fixture body 210 has a positioning part 211 and an output shaft fixing part 212. The output shaft fixing part 212 is used to fix itself to the servo motor output shaft 110. In this embodiment, the fixing method between the output shaft fixing part 212 and the servo motor output shaft 110 is not limited, as long as it can be fixed to the servo motor output shaft 110 and the fixture body 210 rotates synchronously with the servo motor output shaft 110. The fixture body 210 can be a one-piece structure, providing higher positioning accuracy.

[0045] An angle positioning component 230 is disposed on the positioning part 211 and fixed to the servo output shaft 110 on the output shaft fixing part 212. When the servo output shaft 110 rotates to the target angle, the angle positioning component 230 can form a limit with the servo 100.

[0046] like Figure 4 As shown, a slot 2111 is provided on the positioning part 211. The angle positioning component 230 can be selectively fixed at different positions on the slot 2111. For example, the angle positioning component 230 can slide along the slot 2111. When adjusted to a suitable position, it can be locked to fix the position of the angle positioning component 230 on the positioning part 211. Those skilled in the art will understand that the servo output shaft angle positioning fixture 200 uses the angle positioning component 230 and the limiting position of the servo 100 at a certain position to achieve the positioning of the target angle of the servo output shaft 110. Therefore, by changing the fixed position of the angle positioning component 230, the target angle that the servo output shaft angle positioning fixture 200 can position can be changed. In this embodiment, by adjusting the fixed position of the angle positioning component 230 on the slot 2111, different target angles can be achieved.

[0047] Furthermore, in another embodiment of this application, the positioning part 211 may also have multiple fixing holes, and the angle positioning component 230 can be selectively fixed to one of the fixing holes. Similar to the above embodiments, by fixing the angle positioning component 230 to different fixing holes, different target angles can be achieved. Those skilled in the art will understand that, compared with the strip groove 2111 solution disclosed in the above embodiments, the adjustable target angle of the multiple fixing holes disclosed in this embodiment is the corresponding angle corresponding to each fixing hole. Therefore, the angle positioning component 230 can be fixed in the corresponding fixing hole according to different servo models to match the corresponding servo model.

[0048] like Figure 3 and Figure 6 As shown, in this embodiment, the angle positioning assembly 230 includes a fastener 231 and an angle positioning member 232. The fastener 231 is used to fix the angle positioning member 232 onto the positioning part 211. The angle positioning member 232 has a fastening screw hole 2321. The screw portion of the fastener 231 passes through the slot 2111 and is threaded into the fastening screw hole 2321. The nut of the fastener 231 and the angle positioning member 232 are respectively clamped on both sides of the positioning part 211. When it is necessary to adjust the target angle of the servo output shaft 110 to be positioned, simply loosen the fastener 231 to reduce the clamping force of the nut of the fastener 231 and the angle positioning member 232 on the positioning part 211. Then, the angle positioning assembly 230 can be moved along the slot 2111. After moving to the appropriate position, tighten the fastener 231 so that the nut of the fastener 231 and the angle positioning member 232 are clamped onto the positioning part 211.

[0049] It should be noted that the angle positioning component 232 can be entirely located on one side of the positioning part 211, or it can be equipped with a slider that can be embedded in the strip groove 2111, and the slider can slide back and forth along the strip groove 2111. The fastener 231 can cooperate with the fastening screw hole 2321 on the angle positioning component 232, so that the positioning part 211 is clamped by the nut of the fastener 231 and the angle positioning component 232, thereby fixing the angle positioning assembly 230. Alternatively, a slider can be provided on the angle positioning component 232 and embedded in the strip groove 2111, and the slider can be pressed against the strip groove 2111 by a set screw, thereby fixing the angle positioning assembly 230.

[0050] When the servo output shaft angle positioning fixture 200 rotates with the servo output shaft 110, the angle positioning component 232 needs to form a limit with a certain position of the servo 100 (such as the upper surface 120 of the servo) to prevent the rotation of the servo output shaft 110. When the angle positioning component 232 forms a limit with the upper surface 120 of the servo, it needs to collide with the upper surface 120 of the servo. In order to prevent damage to the upper surface 120 of the servo caused by the collision, and damage to the angle positioning component 232 caused by the collision, in this embodiment, the angle positioning component 232 can be designed as a cylindrical structure, and the material of the angle positioning component 230 can be designed as metal, such as copper or steel.

[0051] When the servo output shaft angle positioning fixture 200 rotates with the servo output shaft 110, the angle positioning component 232 will form a limit with a certain position of the servo 100 (such as the upper surface 120 of the servo). For example, the angle positioning component 232 may collide with the upper surface 120 of the servo. The angle positioning component 232 is fixed to the corresponding position of the slot 2111 by the fastener 231. If the collision force is too large, or if the clamping force of the nut of the fastener 231 and the angle positioning component 232 on the positioning part 211 is too small, the angle positioning component 232 will move along the slot 2111, which will inevitably affect the positioning accuracy of the target angle.

[0052] Based on this, in this embodiment, a first friction texture (not shown in the figure) is provided on the side of the positioning part 211 facing the nut of the fastener 231. That is, some texture is provided on the side of the positioning part 211 facing the nut of the fastener 231 to improve the friction. It should be noted that the first friction texture should be arranged on the path of the strip groove 2111, that is, the first friction texture needs to be arranged on both sides of the strip groove 2111.

[0053] A washer is fitted onto the fastener 231. The washer has a second friction pattern (not shown in the figure) that mates with the first friction pattern; that is, the second friction pattern is provided on the side of the washer facing the positioning part 211. When the washer is attached to the positioning part 211, the first and second friction patterns can interlock. The nut of the fastener 231 presses the washer tightly onto the positioning part 211.

[0054] With the above solution, even if the collision force between the angle positioning component 232 and the upper surface 120 of the servo motor 100 is too large, the interlocking of the first friction pattern and the second friction pattern can prevent the angle positioning component 232 from moving along the strip groove 2111, thus avoiding the problem of affecting the positioning accuracy of the target angle due to the movement of the angle positioning component 232 caused by the impact.

[0055] Those skilled in the art can set a target angle based on the desired angle of the servo output shaft 110. Specifically, the target angle can be obtained by designing the positional relationship between the servo output shaft 110 and the angle positioning component 230 on the fixture body 210. This servo output shaft angle positioning fixture 200 can provide the same target angle setting for servos 100 of the same model. It should be noted that the target angle can be the initial angle of the servo or other angles. The servo output shaft angle positioning fixture 200 disclosed in this embodiment can position any angle as needed, facilitating operators to quickly rotate the servo output shaft 110 to the target angle.

[0056] The servo output shaft angle positioning fixture 200 disclosed in this application, when used for setting the target angle of the servo output shaft 110, requires fixing the output shaft fixing part 212 of the fixture body 210 to the servo output shaft 110, so that when the servo output shaft 110 is rotated, the servo output shaft angle positioning fixture 200 rotates synchronously. When rotating in the corresponding direction until the angle positioning member 232 and the servo form a limit, the servo output shaft 110 can no longer rotate in that direction, and the angle of the servo output shaft 110 at this time is the target angle to be set. With the servo output shaft angle positioning fixture 200 disclosed in this application, it is unnecessary to measure the servo output shaft 110 multiple times when setting the target angle, thus improving the efficiency of setting the servo target angle.

[0057] The angle positioning component 232 is designed as a cylindrical structure, making its outer surface relatively smooth. This prevents damage to the upper surface 120 of the servo motor due to sharp edges upon collision. Specifically, the angle positioning component 232 can be designed as a cylinder with a diameter of 4-8mm and a length of 8-12mm. The specific dimensions of the angle positioning component 232 can be designed according to requirements and are not limited to the above-mentioned range.

[0058] The angle positioning component 230 is designed to be made of metal, which gives it high strength and allows it to withstand multiple positioning uses.

[0059] In a specific embodiment of this application, the positioning part 211 and the output shaft fixing part 212 are connected by the connecting part 213. The distance between the positioning part 211 and the output shaft fixing part 212 can be increased by the connecting part 213, thereby increasing the rotation radius of the angle positioning component 230 so that the angle positioning component 230 can form a limit with the upper surface 120 of the servo motor.

[0060] The positioning part 211 and the output shaft fixing part 212 extend from the connecting part 213 to different sides, such that after the output shaft fixing part 212 is fixed to the servo output shaft 110, the positioning part 211 extends toward the upper surface 120 of the servo. It should be noted that the positioning part 211 and the output shaft fixing part 212 may also extend from the connecting part 213 to the same side. In this embodiment, the extending direction of the positioning part 211 and the output shaft fixing part 212 is not limited.

[0061] Furthermore, the extending directions of the positioning part 211 and the output shaft fixing part 212 can be designed to be parallel, and both perpendicular to the extending direction of the connecting part 213. Those skilled in the art can also design the extending directions of the positioning part 211 and the output shaft fixing part 212 to form a certain angle depending on the limiting position. The extending direction of the strip groove 2111 can be perpendicular to the extending direction of the connecting part 213, that is, the strip groove 2111 extends along the extending direction of the positioning part 211.

[0062] like Figure 3 As shown in a specific embodiment of this application, the output shaft fixing part 212 has an output shaft mounting hole 2121 for cooperating with the servo output shaft 110 and a clamping groove 2122 that penetrates the output shaft fixing part 212 and communicates with the output shaft mounting hole 2121. The servo output shaft 110 is usually a quadrangular prism structure, so the output shaft mounting hole 2121 can also be designed as a quadrangular hole structure; of course, the servo output shaft 110 can also be other shapes, such as cylindrical, etc., as long as the output shaft mounting hole 2121 is designed to be the same shape as the servo output shaft 110. That is, the output shaft mounting hole 2121 should be machined according to the shape and size of the servo output shaft 110. If the servo output shaft 110 has a special shape, the shape of the output shaft mounting hole 2121 can be changed according to the structure of the servo output shaft 110. In order to ensure positioning accuracy and avoid the influence of transmission error and return error on positioning accuracy, the tolerance of the output shaft mounting hole 2121 needs to be controlled.

[0063] The clamping groove 2122 divides the output shaft fixing part 212 into two clamping arms 2124. The servo output shaft angle positioning fixture also includes a clamping assembly 220 for clamping the two clamping arms 2124. The width of the clamping groove 2122 can be 2mm, or it can be designed to other sizes according to requirements.

[0064] After the servo output shaft 110 is inserted into the output shaft mounting hole 2121, there should be no obvious gap between the output shaft mounting hole 2121 and the servo output shaft 110. Then, the clamping assembly 220 presses the two clamping arms 2124, so that the servo output shaft 110 is clamped in the output shaft mounting hole 2121, ensuring the positioning accuracy of the servo output shaft 110.

[0065] like Figures 3-5 As shown, in this embodiment, the clamping assembly 220 may include a connecting screw 222, a connecting nut 223, and a quick-release control component 221. Both clamping arms 2124 have clamping through holes 2123 for the connecting screw 222 to pass through.

[0066] The quick-release control component 221 has a cam portion 2211, and one end of the connecting screw 222 is eccentrically hinged to the quick-release control component 221. For example, one end of the connecting screw 222 can be hinged to the cam portion 2211 via a hinge shaft 224, and the other end of the connecting screw 222 passes through the clamping holes 2123 on the two clamping arms 2124 and engages with the connecting nut 223. Through the engagement of the connecting screw 222 and the connecting nut 223, the clamping assembly 220 is mounted onto the output shaft fixing portion 212.

[0067] The quick-release control component 221 and the connecting nut 223 are located on both sides of the output shaft fixing part 212. By rotating the quick-release control component 221, the cam part 2211 can be driven to rotate. The cam part 2211 abuts against one of the clamping arms 2124. During the rotation of the cam part 2211, the distance between the hinge shaft 224 and the clamping arm 2124 can be changed, thereby achieving the purpose of driving the two clamping arms 2124 to clamp and release. For example, when the quick-release control component 221 is rotated in the first direction, the two clamping arms 2124 can be clamped, and when the quick-release control component 221 is rotated in the second direction (opposite to the first direction), the two clamping arms 2124 can be released.

[0068] It should be noted that the quick-release control component 221 should have a relatively long control lever 2212 to achieve the purpose of reducing the effort required to rotate the quick-release control component 221. Since the connecting screw 222 and the quick-release control component 221 will rotate relative to each other when the quick-release control component 221 is rotated, in order to prevent interference between the connecting screw 222 and the quick-release control component 221, a clearance groove 2213 is provided on the quick-release control component 221. When the quick-release control component 221 rotates, the connecting screw 222 rotates within the clearance groove 2213.

[0069] In this embodiment, the clamping assembly 220 is designed as a quick-release structure. During the clamping and releasing process of the clamping arms 2124, there is no need to rotate the connecting nut 223; only the quick-release control component 221 needs to be swung. Due to the fewer rotations, faster operation can be achieved, improving clamping efficiency. By rotating the connecting screw 222 and / or the connecting nut 223, the clamping force on the two clamping arms 2124 when rotating the quick-release control component 221 can be adjusted.

[0070] It should be noted that the clamping assembly 220 can also clamp the two clamping arms 2124 with fasteners, and is not limited to the quick-release structure disclosed in the above embodiments.

[0071] To ensure that the servo output shaft angle positioning fixture 200 does not scratch the structural housing of the servo output shaft 110 and the servo 100 during target angle positioning, and to ensure that the appearance is intact, the fixture body 210 is made of plastic.

[0072] In summary, the servo motor output shaft angle positioning fixture 200 disclosed in this application has the following technical effects:

[0073] 1) The clamping assembly 220 ensures that the output shaft mounting hole 2121, which mates with the servo output shaft 110, can clamp the servo output shaft 110, ensuring that there is no gap or backlash between the servo output shaft 110 and the output shaft mounting hole 2121, thus ensuring positioning accuracy.

[0074] 2) The servo motor output shaft angle positioning fixture 200 can achieve quick clamping and loosening, and is easy to disassemble, thus improving positioning efficiency;

[0075] 3) The target angle to be positioned of the servo output shaft angle positioning fixture 200 is adjustable, which can be used for positioning of various models of servos and multiple angles of the same model of servo, thereby improving the applicability and reducing costs.

[0076] Based on the above functional and process descriptions, the initial angle of the servo motor output shaft needs to ensure initial position accuracy to avoid control errors caused by initial position errors.
