Detailed Description
The following describes the embodiments of the present invention in further detail by way of examples with reference to figures 1 to 10.
A turnover tool for a low-speed high-torque motor stator comprises a base plate 10, wherein the base plate 10 and a stator core A form detachable matching connection, and lifting lugs 20 are arranged on the outer side plate surface of the base plate 10. When the lifting device is used, the base plates 10 of the two overturning tools are required to be symmetrically arranged on two sides of the stator core A respectively, then the flexible belt-shaped lifting appliance of the lifting device is sleeved on the lifting lugs 20, and as the axes of the two lifting lugs 20 are coincident, after the lifting device is started and the stator is lifted to a proper position, the stator overturns by taking the axes of the two lifting lugs 20 as a rotating shaft, so that the posture adjustment is realized. The overturning tool has a simple structure, and can be matched with the lifting device to conveniently realize overturning of the stator and avoid coil damage caused by collision of the end part of the stator.
Preferably, the lifting lug 20 comprises a turnover part 21 which is in rotary fit with the flexible belt-shaped lifting appliance, and the outer circumferential surface of the turnover part 21 is a smooth cylinder/round table surface. This allows the lifting lugs 20 to be well fitted to the spreader, thereby ensuring a continuous and reliable turning action of the stator. As shown in fig. 5 and 6, the turning portion 21 has a cylindrical shape, and in other embodiments, the turning portion 21 may have a truncated cone shape. When the turnover part 21 is a circular table with a large outer diameter at the side far away from the base plate 10 and a small outer diameter at the side close to the base plate 10, the product damage caused by the fact that the belt-shaped lifting tool is separated from the lifting lug 20 can be effectively prevented.
Preferably, as shown in fig. 1 and 3, the axis of the turning portion 21 intersects with the axis of the substrate 10 in the longitudinal direction, and the axes are perpendicular to each other. When the turnover part 21 is used, as shown in fig. 7 and 9, the turnover part 21 is also arranged at intervals from the middle point in the axial direction of the stator, so that the connecting line of two hanging points of the lifting device is arranged at intervals from the center of the stator, and the stator is in an eccentric hanging state after being lifted, therefore, the stator automatically rotates around the connecting line of the hanging points due to poor quality of two sides of the hanging points, and the automatic turnover of the lifted stator is realized.
Further, a stop block 22 is disposed on the outer side of the turnover portion 21, and a block body of the stop block 22 protrudes radially along the stop block, so that the maximum outer diameter of the stop block 22 is larger than the outer diameter of the joint of the turnover portion 21 and the stop block 22. Thus, the stability and the reliability of the coordination of the belt-shaped lifting appliance and the lifting lug can be ensured.
Preferably, two positioning plates 11 are symmetrically arranged in the width direction of the substrate 10, and the whole plate body of the positioning plates 11 extends along the length direction of the substrate 10. As shown in fig. 2, 5 and 7, the positioning plate 11 can avoid the problem of unstable connection caused by too small fitting area between the strip-shaped substrate 10 and the outer peripheral surface of the arc-shaped stator core a; when the peripheral wall of the stator core a is provided with connecting ribs along the axial direction thereof, the concave portion formed by the positioning plate 11 and the base plate 10 can also form a snap fit connection with the connecting ribs, thereby further improving the reliability of the turnover tool.
Preferably, the substrate 10 is a strip-shaped plate with a large middle part and small two ends. As shown in fig. 1 and 3, the width of the base plate 10 where the lifting lug 20 is arranged is larger, so that the reliability of the connection between the lifting lug 20 and the base plate 10 can be ensured.
Preferably, the plate body of the base plate 10 is provided with a connecting hole 12, the position and the aperture of the connecting hole 12 are consistent with those of the process hole of the stator core a, and the base plate 10 and the stator core a form threaded connection. As shown in fig. 1 and 3, the connection hole 12 may be a screw hole or a waist hole depending on the size and type of the stator core a.
The application method of the turnover tool comprises the following steps:
Step 1, symmetrically installing two overturning tools on two sides of a stator core A respectively, enabling the axes of two lifting lugs 20 to coincide, and enabling the axes of the lifting lugs 20 to deviate from the center of gravity of the stator;
step 2, sleeving and hanging a flexible belt-shaped lifting appliance of the lifting device on lifting lugs 20 of two overturning tools, then starting the lifting device, and maintaining the horizontal posture of the stator by an operator;
And 3, recording the distances between the axis of the lifting lug 20 and the end parts of the two ends of the stator as L1 and L2, wherein L1 is larger than L2, and after the stator to be turned over is lifted upwards, when the distance D between the bottom of the stator in a horizontal posture and the working surface at the bottom of the stator is larger than L1, removing the external force for maintaining the posture of the stator by an operator, and automatically turning the stator from the horizontal posture to the vertical posture under the action of gravity to finish the turning operation of the stator.
Here, the distance between the intersection point of the axis of the turning portion 21 and the longitudinal axis of the base plate 10 and the midpoint of the longitudinal axis of the base plate 10 and the distance between the axis of the lifting lug 20 and the center of gravity of the stator should be small. In this way, the operator can maintain the attitude of the stator by slightly applying force; in practical application, the center of gravity of the stator is difficult to completely coincide with the geometric center of the stator, so that after an operator removes the external force for maintaining the posture of the stator, the stator can maintain balance under the hanging of the lifting device, and the operator only needs to apply small force to finish the overturning of the stator.
The overturning operation of the stator is simple and reliable, the application range is wide, and the overturning device is particularly suitable for overturning the stator from a horizontal posture to a vertical posture, so that the working difficulty of overturning the stator is greatly reduced, and the assembly efficiency and the assembly quality are improved.
