[0003] After searching, the Chinese patent application number 202320896827.X discloses a motor coil coaxiality calibration tool, which relates to the field of motor assembly tooling, including a base and an auxiliary shaft. A placement groove for supporting the protective shell A and a limiting groove for supporting the auxiliary shaft are formed on the base. The curvature radius of the placement groove is greater than the curvature radius of the limiting groove, and the line connecting the curvature centers of the placement groove and the limiting groove coincides with the axis of the auxiliary shaft. By setting the calibration tool, under the limiting action of the base and the auxiliary shaft, the axes of the motor protective shell A and the motor coil B can always remain in a coincidence state during the assembly and fixation process; in addition, under the action of the pressing plate, the state of the motor protective shell A and the motor coil B axes not coinciding caused by manual work during the motor assembly or fixation process can be calibrated to an axis coincidence state during pressing, and the two can be pre-fixed, so that the motor protective shell A and the motor coil B always remain coaxial. Compared with the prior art, the utility model can effectively reduce the scrap rate after the motor is assembled. The above patent has the following shortcomings in use: when in use, the pressing plate needs to be constantly moved up and down from the base, which increases the workload and reduces production efficiency, and it is inconvenient to intuitively judge the coaxiality between the two, affecting the use effect.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Example:

[0024] Reference Figure 1-Figure 4A motor coil coaxiality calibration tool includes a base 1, on which a lower limit groove 101 and a lower placement groove 102 are opened. Here, two groups of lower limit grooves 101 and lower placement grooves 102 are symmetrically arranged, so that two groups of workpieces can be calibrated at the same time. It also includes: a pressing plate 2, which is set to be lifted and lowered on the top of the base 1, and an upper limit groove 201 and an upper placement groove 202 corresponding to the lower limit groove 101 and the lower placement groove 102 are opened on the pressing plate 2, that is, the upper limit groove 201 and the upper placement groove 202 are also symmetrically arranged in two groups, and a lifting part for driving the pressing plate 2 to be lifted and lowered is arranged on the base 1. When in use, by placing the workpiece on the base 1, and then driving the pressing plate 2 to be lifted and lowered through the lifting part, it is convenient to calibrate the workpiece, and it can avoid frequent handling of the pressing plate 2, reduce labor, and improve the use effect; a second micrometer 402 for detecting the coaxiality of the auxiliary shaft is arranged on the pressing plate 2; a first micrometer 401 for detecting the coaxiality of the motor casing is slidably arranged on the pressing plate 2. When in use, by arranging the first micrometer 401 and the second micrometer 402 on the pressing plate 2, the coaxiality of the auxiliary shaft and the motor casing can be visually detected respectively, which is convenient for judging whether the coaxiality meets the requirements. If the requirements are met, the calibration process can be omitted, which can improve production efficiency.

[0025] Reference Figure 1 A guide groove 203 is provided on the pressure plate 2, and a mounting seat 4 is slidably arranged in the guide groove 203. The first micrometer 401 is set on the mounting seat 4, and the measuring rod of the first micrometer 401 is extended upward into the groove 202. When inspecting the motor casing, the mounting seat 4 can be pushed to slide back and forth along the guide groove 203 with the first micrometer 401, so as to realize sliding inspection from one end to the other end of the motor casing, thereby improving the inspection range.

[0026] Reference Figure 1 and Figure 2 The lifting part can use a cylinder, a hydraulic cylinder or an electric telescopic cylinder to drive the pressing plate 2 to lift. Here, we design the lifting part as follows: a screw rod 3 is rotatably set on the base 1, and a limit block is rotatably set in the base 1. One end of the screw rod 3 is fixedly connected to the limit block, and the pressing plate 2 is threadedly connected to the screw rod 3, and a knob 301 is fixedly set on the end of the screw rod 3 that passes through the pressing plate 2. When in use, the screw rod 3 is driven to rotate by the knob 301, which can drive the pressing plate 2 to move closer to or away from the base 1 to achieve calibration detection, and can avoid frequent handling of the pressing plate 2, which can reduce physical exertion and improve the use effect.

[0027] Reference Figure 1 and Figure 2, multiple groups of guide rods 302 are fixedly arranged on the base 1, and the guide rods 302 are arranged in two to six groups. Here, we prefer four groups, and the four groups are evenly arranged on the base 1, and the four groups of guide rods 302 are all slidably connected with the pressing plate 2. When in use, by fixing the guide rods 302 on the base 1, the pressing plate 2 can be reliably lifted and lowered, and the use effect can be improved. Here, a vertical plate can also be fixedly arranged on the base 1, and the vertical plate is slidably connected with the pressing plate 2 to limit the pressing plate 2.

[0028] Reference Figure 1-Figure 4 A limit seat 5 is fixedly arranged on the outer wall of the lower limit slot 101, and a rotating seat 6 is rotatably arranged on the limit seat 5. A plug-in slot 601 corresponding to the end of the auxiliary shaft is opened on the rotating seat 6, and a handle 603 is rotatably arranged on the outer wall of the rotating seat 6. When in use, when the auxiliary shaft is placed in the lower limit slot 101, the end of the auxiliary shaft is inserted into the plug-in slot 601. When detecting the coaxiality, the rotating seat 6 can be driven to rotate through the handle 603, and the rotating seat 6 can rotate with the auxiliary shaft to improve the detection effect.

[0029] Reference Figure 3 and Figure 4 A rotation groove 501 is opened on the limit seat 5, and an annular plate 602 is fixedly arranged on the rotating seat 6. The annular plate 602 is rotatably set in the rotation groove 501. When in use, by rotatably setting the annular plate 602 in the rotation groove 501, the rotating seat 6 can be ensured to rotate reliably, and the rotating seat 6 can be prevented from falling off from the limit seat 5, affecting normal use.
