[0002] Fork-type servos are widely used in robotics, model aircraft, and industrial automation. Their core adjustment requirements include neutral point calibration, travel limit adjustment, and backlash elimination. Currently, adjusting fork-type servos primarily involves using a tape measure, calipers, or micrometer, supplemented by materials such as angle iron or I-beams. The main problems with this method are relatively poor accuracy and a slow adjustment process; it also wastes materials (different servo sizes require different sizes of materials). Utility Model Content

[0003] The purpose of this invention is to provide a device for quickly adjusting a fork-type servo, in order to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0009] The above technical solution, by setting a positioning nut and a guide rod, can be used on various models and sizes of shift fork servos, eliminating material waste, with a wide range of applications and low cost, and is worthy of widespread promotion and use.

[0010] A further improvement of the present invention is that the marking needle includes a threaded section, a smooth section and a tip arranged in sequence; the threaded section is screwed to the locking nut.

[0011] A further improvement of this utility model is that the measuring needle includes a second threaded section, a second smooth section, and a ball end arranged in sequence; the second threaded section is screwed to the locking nut.

[0012] A further improvement of this utility model is that it also includes an adjusting block, which is slidably connected in the mounting groove; the adjusting block is screwed to the scribing needle and the measuring needle respectively.

[0013] By adopting the above technical solution, the scribing needle and measuring needle can be installed on the measuring ruler at the same time by setting the adjustment block, eliminating the need to replace the scribing needle and measuring needle during the adjustment process, thus further improving the efficiency of the adjustment fork.

[0014] A further improvement of this utility model is that: the adjusting block is provided with a sliding rod and a directional block; the sliding rod is slidably connected to a groove opened in the measuring ruler; and the directional block is fixedly connected to the adjusting block.

[0027] The present invention will be further described in detail below with reference to embodiments:

[0028] Example 1

[0029] like Figures 1-4 As shown, this utility model provides a device for quickly adjusting a fork-type servo, including a measuring ruler 1, a scribing needle 4, a locking nut 6, and a servo stick 7; it may also include a positioning nut 2, a guide rod 3, a fixing bolt 5, and a measuring needle 8.

[0030] Specifically, a measuring scale 1 is installed on the rudder 7; the measuring scale 1 has an installation groove; a scribing needle 4 is installed in the installation groove; the scribing needle 4 is detachably installed on the measuring scale 1 by means of a locking nut 6.

[0031] In this embodiment, the measuring ruler 1 is generally rectangular, with a through hole at one end allowing the fixing bolt 5 to be screwed onto the guide rod 3. The other end has a mounting groove for mounting the scribing needle 4 or the measuring needle 8. More specifically, in this embodiment, the end face of the measuring ruler 1 is square, measuring 40*40mm, with a length of 1500mm. The diameter of the through hole is 17mm, slightly larger than the thread outer diameter of the fixing bolt 5 but smaller than the bolt head outer diameter, facilitating the passage of the fixing bolt 5 while allowing it to fit snugly against the surface of the measuring ruler 1, thus limiting its movement. The mounting groove is 11mm wide and 500mm long, allowing the scribing needle 4 or the measuring needle 8 to move freely within it. Of course, in other embodiments, the dimensions can be adjusted according to the size of the servo motor or rudder stick.

[0032] The scribing needle 4 includes a threaded section, a smooth section, and a tip arranged sequentially; the threaded section is screwed onto the locking nut 6. In this embodiment, the outer diameter of the scribing needle 4 is 10mm, slightly smaller than the width of the mounting groove; the length of the threaded section is 131mm; the length of the smooth section is 19mm; and the tip is tapered with a length of 10mm. Of course, in other embodiments, the specifications of the scribing needle 4 can be larger or smaller, depending on the size of the servo or rudder stick.

[0033] The rudder 7 has a groove; a positioning nut 2 is installed in the groove, and a guide rod 3 is rotatably connected in the positioning nut 2; a fixing bolt 5 is screwed onto the guide rod 3.

[0034] The guide rod 3 can rotate freely within the positioning nut 2. When the fixing bolt 5 passes through the measuring ruler 1 and is screwed onto the guide rod 3 until the bolt head of the fixing bolt 5 is tightly fitted with the measuring ruler 1, the measuring ruler 1 is securely mounted on the rudder spur 7 and can rotate around the guide rod 3 so that the scribing needle 4 or measuring needle 8 is close to the fork groove to be measured. In this embodiment, the inner diameter of the positioning nut 2 is set to 30mm, the outer diameter is set to 50mm, and a positioning groove is formed inside the positioning nut with a depth of 25mm and an inner diameter of 10mm. The outer diameter of the guide rod 3 is set to 30mm, and a threaded groove matching the fixing bolt 5 is formed inside. The inner diameter of the threaded groove is set to 16mm and the depth is set to 20mm. Of course, in other embodiments, the specifications of the positioning nut 2, guide rod 3, and fixing bolt 5 can be larger or smaller, depending on the size of the servo or rudder spur.

[0035] The measuring needle 8 is detachably mounted on the measuring ruler 1 via a locking nut 6. The measuring needle 8 includes a threaded section two, a smooth section two, and a ball end arranged sequentially; the threaded section two is screwed to the locking nut 6. In this embodiment, the outer diameter of the threaded section two is 10mm, its length is slightly less than the width of the mounting groove, the length of the threaded section two is 131mm, the length of the smooth section two is 19mm, and the ball end is shaped like a ball-head cone with a length of 9mm. The length of the measuring needle 8 is slightly less than the length of the scribing needle 4. Of course, in other embodiments, the specifications of the measuring needle 8 can be larger or smaller, depending on the size of the servo or rudder stick.

[0036] During the actual adjustment process, firstly, power on the servo to return it to the factory-preset neutral position. Then, insert the measuring needle 8 into the shift fork slot and check if the gap between the needle and both sides of the slot is uniform. If asymmetrical, record the direction and distance of the deviation. Draw a baseline on the side of the shift fork using the scribing needle 4, aligning it with the reference line on the servo housing. Input the maximum or minimum PWM signal to the servo and use the measuring needle 8 to detect the limit displacement of the shift fork slot, calculating whether the actual travel matches the preset value. If the travel is insufficient, mark the original position at the servo potentiometer or limit screw using the scribing needle 4, gradually adjust, and then re-scibble to confirm. Secure the guide rod 3 with the fixing bolt 5, lightly touch one side of the shift fork slot with the measuring needle 8, manually shake the shift fork, and use a dial indicator to measure the axial movement. If the backlash is too large, adjust the preload of the shift fork support bearing or replace the worn gear. Mark the screw positions before and after adjustment with the scribing needle 4.

[0037] In this embodiment, the direction and distance that the servo fork needs to be adjusted are measured by fixing bolt 5, and then the scriber pin 4 is replaced to adjust the fork, achieving rapid and precise adjustment of the servo fork with an adjustment accuracy within 0.1mm. At the same time, by setting up the adjustment structure, it can be used on multiple models and sizes of fork-type servos, eliminating material waste, with wide applicability and low cost, making it worthy of widespread promotion and use.

[0038] Example 2

[0039] like Figures 5-7 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, it further includes an adjusting block 9. The adjusting block 9 is slidably connected in the mounting groove; the adjusting block 9 is screwed to the scribing needle 4 and the measuring needle 8 respectively. By installing the adjusting block 9, the scribing needle 4 and the measuring needle 8 can be installed on the measuring ruler 1 simultaneously. By adjusting the direction of the scribing needle 4 and the measuring needle 8, the direction of the scribing needle 4 and the measuring needle 8 can be reversed, realizing rapid switching between the scribing needle 4 and the measuring needle 8, effectively improving the adjustment speed.

[0040] Specifically, the adjusting block 9 is equipped with a sliding rod 91 and an directional block 92; the sliding rod 91 is slidably connected to a groove opened in the measuring ruler 1; the directional block 92 is fixedly connected to the adjusting block 9. A marking line or elastic plate matching the directional block 92 is provided in the mounting groove. The scribing needle 4 and the measuring needle 8 are arranged back-to-back and parallel, and are respectively screwed or fixedly connected to the adjusting block 9. In practical applications, the distance between the tip, ball end, and sliding rod 91 can be adjusted according to actual needs. The scribing needle 4 and the measuring needle 8 can still be fixed using locking nuts 6, and when the two sets of locking nuts 6 respectively provided on the scribing needle 4 and the measuring needle 8 are simultaneously and tightly fitted onto the measuring ruler 1, the scribing needle 4 and the measuring needle 8 are exactly perpendicular to the measuring ruler 1, achieving orientation of the scribing needle 4 and the measuring needle 8. Furthermore, the orientation of the scribing needle 4 and the measuring needle 8 can also be achieved by matching the directional block 92 with the marking line or elastic plate, so that one end of the directional block 92 coincides with the marking line or elastic plate.

[0041] By setting the adjusting block 9, both the scribing needle 4 and the measuring needle 8 can be installed on the measuring ruler 1 simultaneously, eliminating the need to replace the scribing needle 4 and the measuring needle 8 during adjustment, thus effectively improving the efficiency of the adjusting fork. In some embodiments, the mounting slot on the measuring ruler 1 can also be made open to prevent interference between the scribing needle 4, the measuring needle 8 and the measuring ruler 1 during the rotation of the adjusting block 9. Simultaneously, the sliding rod 91 can be rotatably connected to the adjusting block 9, with external threads on it. Upon completion of positioning, the sliding rod 91 is fixed relative to the measuring ruler 1 by an external nut, allowing the scribing needle 4 and the measuring needle 8 to be rotated for quick position changes without the need for repositioning, effectively improving adjustment efficiency.

[0042] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
