[0024] To make the objectives, contents, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0025] Reference Figure 1 This embodiment of the assembly and disassembly fixture for the variable size of the threaded pressure ring includes a main body 1, a torque rod 2, a locking nut 3, a disassembly and assembly mechanism 4, and an adjustment mechanism 5. The main body 1 is rod-shaped, with the torque rod 2 vertically mounted on the upper end, and a slider of the adjustment mechanism 5 sleeved in the middle. The locking nuts 3 are threadedly installed at both ends of the slider. The disassembly and assembly mechanism 4 includes two arms, each with two support arms hinged to its upper end. Of the two support arms, the two lower support arms are hinged to the lower end of the main body 1, and the two upper support arms are hinged to both sides of the slider.

[0026] The adjustment mechanism 5 includes a slider and lugs on both sides of the slider. The slider is sleeve-shaped, and the lugs are hinged to the support arm.

[0027] Mounting seats are provided at the upper ends of the two arms of the disassembly and assembly mechanism 4, and one end of the upper support arm and the lower support arm are coaxially hinged to the mounting seats.

[0028] The two arms of the disassembly and assembly mechanism 4 are referred to as the left arm and the right arm. The two arms on the left arm are referred to as the upper left arm and the lower left arm, respectively, and the two arms on the right arm are referred to as the upper right arm and the lower right arm, respectively.

[0029] One end of the upper left support arm and one end of the lower left support arm are hinged to the upper part of the left arm. The other end of the upper left support arm is hinged to the lug on one side of the slider, and the other end of the lower left support arm is hinged to the lower end of the main body 1.

[0030] One end of the upper right support arm and one end of the lower right support arm are hinged to the upper part of the right arm. The other end of the upper right support arm is hinged to the other side of the slider lug, and the other end of the lower right support arm is hinged to the lower end of the main body 1.

[0031] The other ends of the left lower support arm and the right lower support arm are hinged at the same point.

[0032] The upper end of the main body 1 has a through hole, and the torque rod 2 is inserted into the through hole. The inner diameter of the through hole matches the outer diameter of the torque rod 2.

[0033] The middle section of the main body 1 is an adjustment section for adjusting the position of the slider. The outer diameter of the adjustment section is larger than the diameter of the two ends.

[0034] The outer diameter of the adjustment section in the middle of the main body 1 matches the inner diameter of the slider.

[0036] Combination Figure 1The distance between the two arms of the disassembly and assembly mechanism 4 can be continuously changed by altering the position of the slider on the adjustment mechanism 5, thereby adapting to different sizes of threaded pressure rings. Tightening the locking nut 3 fixes the position of the slider on the adjustment mechanism 5, thus fixing the distance between the two arms of the disassembly and assembly mechanism 4 and preventing changes in distance during assembly and disassembly. This enables the assembly / disassembly of threaded pressure rings of different sizes, improving the assembly efficiency of the shaft system in small servo systems.

[0039] Combination Figure 3 The minimum adjustable distance between the two arms of the disassembly and assembly mechanism corresponds to the smallest size of the threaded pressure ring that can be fitted.
