[0028] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0029] like Figures 1 to 4 As shown, the utility model provides a precision torque motor assembly tool, including: a base 1, an upper main disk 2, a rotor connecting disk 3, a driving screw 4 and an adjustment limiter 5, wherein the upper main disk 2 is arranged above the base 1, and the upper main disk 2 and the base 1 are parallel to each other; a plurality of columns 10 are arranged on the base 1, and the columns 10 are suitable for supporting the upper main disk 2. The motor stator is suitable for being placed on the base 1, and the base 1 is suitable for limiting and fixing the motor stator; the driving screw 4 is threadedly adapted to the upper main disk 2, the driving screw 4 is vertically arranged, and the rotor connecting disk 3 is fixed at the lower end of the driving screw 4; the driving screw 4 is circumferentially rotated, which is suitable for driving the rotor connecting disk 3 to move vertically upward or downward. Every two of the limit adjustment blocks are symmetrically and slidably arranged at the lower end of the rotor connecting disk 3, and the limit adjustment blocks are suitable for abutting against the inner wall of the groove at the upper end of the rotor; wherein, when any one of the adjustment blocks is pushed to move inward, the other relatively arranged adjustment limiter 5 is suitable for sliding inward synchronously. By adjusting the coordination between the limiter 5 and the linkage gear 32, stators of different sizes can be adapted, thereby improving the adaptability of the equipment. At the same time, each limit block 51 is transmission-connected with the linkage gear 32, and when any limit block 51 is driven to slide inward, the other limit blocks 51 can slide inward synchronously, thereby improving work efficiency.

[0030] Reference Figure 3A positioning column 31 is fixed at the lower end of the rotor connection disk 3, and a linkage gear 32 is sleeved on the outer wall of the positioning column 31. The linkage gear 32 is suitable for circumferential rotation relative to the positioning column 31. A torsion spring is arranged on the outer wall of the positioning column 31, and the two ends of the torsion spring are respectively fixed on the positioning column 31 and the linkage gear 32. The torsion spring is suitable for pushing the linkage gear 32 to rotate circumferentially so as to make the limit block 51 slide outward. In the initial state, the limit block 51 is located at the outermost end of the rotor connection disk 3. When any limit block 51 is pushed to move toward the axial direction of the rotor connection disk 3, the adjustment rod 52 synchronously pushes the linkage gear 32 to rotate circumferentially, and at this time, the torsion spring is compressed by force. When the driving force on the limit block 51 disappears, the torsion spring is suitable for pushing the linkage gear 32 to return and rotate, so that the limit block 51 can slide outward. When the limit block 51 is located in the groove at the upper end of the rotor, the limit block 51 can abut against the inner wall of the groove of the rotor. The limit blocks 51 cooperate with each other to achieve the effect of clamping the rotor.

[0031] The rotor described in this application is Figure 4 As described above, a groove is provided at the upper end of the rotor, and when the rotor connecting plate 3 abuts against the rotor, the limit block 51 is suitable for being inserted into the groove.

[0032] In order to facilitate the adaptation of rotors of different sizes, the adjustment limiter 5 includes: a limit block 51 and an adjustment rod 52. The adjustment block is slidably arranged at the lower end of the rotor connecting disk 3. In order to improve the stability of the movement of the limit block 51, the rotor connecting disk 3 is provided with a plurality of slide grooves in the radial direction, one slide groove corresponds to one limit block 51, and the limit block 51 is suitable for sliding radially along the slide groove. The limit block 51 is suitable for abutting against the rotor; the adjustment rod 52 is fixed on the inner wall of the limit block 51, and the adjustment rod 52 is adapted to the transmission of the linkage gear 32; when the linkage gear 32 rotates circumferentially, it is suitable for driving the two limit blocks 51 to move toward or away from each other. The two oppositely arranged adjustment rods 52 are respectively arranged on both sides of the linkage gear 32. A linear rack is fixed on the side wall of the adjustment rod 52, and the linear rack is meshed with the linkage gear 32.

[0033] Preferably, there are four limit blocks 51, and the four limit blocks 51 are equidistantly spaced and rotate circumferentially around the rotor connecting plate 3. In order to avoid interference between the four adjustment rods 52, two adjustment rods 52 arranged opposite to each other are perpendicular to the other two adjustment rods 52 arranged opposite to each other, and two of the connecting rods are located below the other two connecting rods. When any limit block 51 is pushed to move inward, the adjustment rod 52 is suitable for driving the linkage gear 32 to rotate circumferentially; and the circumferential rotation of the linkage gear 32 is suitable for driving the other three limit blocks 51 to move inward synchronously, so as to facilitate the simultaneous insertion of each limit block 51 into the groove on the rotor. Through the above arrangement, the trouble of pushing the limit blocks 51 one by one is avoided, and the work efficiency is improved.

[0034] Preferably, a handle 40 is fixed to the end of the driving screw 4, and the handle 40 is perpendicular to the driving screw 4. The arrangement of the handle 40 facilitates the operator to drive the rotor connecting plate 3 to move.
