Description

Technical Field

[0001] This utility model relates to the field of motor assembly, and in particular to a stator assembly placement platform. Technical Background

[0002] In motor assembly processes, the stator assembly is typically fixed and centered, and then the rotor assembly is controlled to move axially to achieve assembly with the stator assembly. In existing technologies, the placement and positioning of the stator assembly needs to consider multiple requirements. On the one hand, stator assemblies come in various models and specifications with different dimensions, so the placement platform must be able to adapt to different stator assembly models. On the other hand, during assembly, a guiding mechanism is often needed to assist in the centering of the rotor assembly to facilitate stator assembly assembly. For example, patent document CN107317440A discloses a top rod assembly for stator assembly positioning and guiding; this type of mechanism needs to pass through the stator assembly from bottom to top to connect with the rotor assembly. Therefore, the stator assembly placement platform must be designed to provide sufficient operating space for the rotor assembly guiding mechanism. Currently, common stator assembly placement platform structures are relatively fixed, lacking the ability to quickly adapt to multiple stator assembly models, and also failing to fully consider the movement requirements of the bottom guiding mechanism, making it difficult to provide a stable and accessible path for bottom-to-top positioning and guiding mechanisms such as top rods while accommodating different stator models. Utility Model Content

[0003] The present invention aims to solve the above problems by providing a stator assembly placement platform that can accommodate different models of stator assemblies while providing sufficient space for the operation of other mechanisms.

The placement plate and the mounting platform are horizontally arranged and mounted above the mounting platform. The rotation drive mechanism contacts the placement plate and is used to drive the placement plate to rotate around a rotation axis perpendicular to the horizontal plane. Each set of support components consists of a support member and a linear module. The linear module is mounted on the mounting platform, and the support member is slidably mounted on the linear module and slides along the length of the linear module. The placement plate is provided with N sets of sliding grooves. The two ends of the sliding grooves are the minimum limit and the maximum limit at different distances from the rotation axis. The minimum limit and the maximum limit are smoothly connected. The width between the two sides of the sliding groove is greater than the diameter of the support. The line connecting the geometric center of the minimum limit and the geometric center of the maximum limit does not pass through the rotation axis. The support member passes through the sliding groove, and the upper surface of the support member extends beyond the plane where the placement plate is located.

[0005] The sliding groove is an arc groove, and the center of the circle corresponding to the arc groove is offset from the rotation axis.

[0006] The linear module is oriented along the rotation axis in the length direction.

[0007] The angle between the line connecting the geometric centers of the maximum and minimum limits and the length direction of the straight module is 120°.

[0010] The arc-shaped rack is installed at the edge of the placement tray, and the arc-shaped rack extends beyond the edge of the placement tray.

[0011] The placement tray is annular, and N sets of sliding grooves are evenly distributed on the annular structure of the placement tray, where N ≥ 3.

[0012] The support member is mounted on the slider via a support column base, and the slider is mounted on the linear module.

[0013] The support consists of a support base and a support column mounted on the support base. The support base is mounted on the mounting platform, and the top of the support column is used to contact the item to be placed.

[0014] The beneficial effects of this utility model are as follows: the stator placement platform can adapt to different models of stator components by adjusting the relative distance between the support components, and can achieve automated control of the support position without replacing parts, reducing changeover time; the structure of this invention is reasonably designed, using an annular placement disk and driving rotation along its edge.

Detailed Implementation

[0017] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] A stator component placement platform, such as Figure 1 and Figure 2 As shown, it consists of: mounting platform 1, rotating component 2, and N sets of support components 3; N≥2.

[0024] The sliding groove 211 is an arc groove, and the center of the circle corresponding to the arc groove is offset from the rotation axis.

In a specific embodiment, the angle between the line connecting the geometric centers of the maximum limit point 2112 and the minimum limit point 2111 of the sliding slot 211 and the length direction of the linear module 32 is set to 120°. Here, the angle refers to the angle between the line connecting the geometric centers of the maximum limit point 2112 and the minimum limit point 2111 of the sliding slot 211 and the length direction of the linear module 32 when the geometric center of the sliding slot 211 is located directly above the linear module 32.

[0030] The distribution of mounting component 4, support component 3, and rotary drive mechanism 22 should avoid mutual interference.

[0031] In one embodiment, such as Figure 6 As shown, the rotary drive mechanism 22 includes an arc-shaped rack 221, a gear 222, and a rotary drive module 223. The gear 222 is horizontally arranged and mounted on the mounting platform 1 via a mounting base 224. Figure 7 As shown, the mounting base 224 includes a left mounting plate 2241, a right mounting plate 2242, and a horizontal mounting plate 2243. The horizontal mounting plate 2243 is mounted on the left mounting plate 2241 and the right mounting plate 2242. The left mounting plate 2241 and the right mounting plate 2242 are respectively mounted on both sides of the square slot of the mounting platform 1. The gear 222 is located above the horizontal mounting plate 2243, and the rotary drive module 223 is located below the horizontal mounting plate 2243. The gear 222 is aligned with the axis of the rotary drive module 223, and the gear 222 rotates around the gear axis under the drive of the rotary drive module 223.

[0032] The center of the circle corresponding to the arc rack 221 is on the rotation axis, the serrations of the arc rack 221 are located on the outer surface of the arc rack 221, and the arc rack 221 meshes with the gear 222.

[0033] In one embodiment, the rotary drive mechanism 22 is further provided with a gear guard 225, which is mounted on the placement plate 21 to protect the gears and related structures.

[0034] The rotary drive module 223 uses a servo motor, and the gear 222 is mounted on the edge of the mounting platform 1 by the mounting base 224. The servo motor passes through the square slot of the mounting platform 1 and connects to the horizontal mounting plate 2243.

[0035] In one embodiment, the arc-shaped rack 221 is installed at the edge of the placement plate 21, and the arc-shaped rack 221 extends beyond the edge of the placement plate 21. The arc-shaped rack 221 protrudes outward and meshes with the gear 222, which can prevent collisions between different mechanisms.

[0036] In one embodiment, the placement tray 21 is designed as a ring, and N sets of sliding slots 211 are evenly distributed on the ring structure of the placement tray 21, where N≥3. The vertical line where the geometric center of the placement tray 21 is located is the axis of rotation, and N sets of support components 3 are evenly distributed on the mounting platform 1 corresponding to the positions of the sliding slots 211.

[0037] In the embodiment shown in the accompanying drawings, the number of sliding slots 211 and support components 3 are both set to 4.

[0040] The support component 31 is designed in two parts. The support base 311 is made of rigid material, which is not easy to deform when moving in the sliding groove 211, making the movement smoother. The support column 312 is made of elastic material, such as polyurethane, which can increase the height and protect the stator assembly from deformation caused by external forces during assembly.

[0041] The operating principle of this utility model is as follows: The drive gear 222 is mounted on the edge of the mounting platform 1 by the mounting base 224. The rotary drive module 223 passes through the square slot of the mounting platform 1 and is mounted directly below the horizontal mounting plate 2243.

A gear protective cover 225 is provided on the outside of the gear structure to protect the gear and related structures. S mounting blocks 41 are evenly distributed on the mounting platform 1. The number of mounting blocks 41 is preferably 2 or more, and in the specific embodiment shown in the figure, it is set to 3. A guide rail 42 is installed above each mounting block 41.

The placement plate 21 has N sets of sliding slots 211 evenly distributed according to different stator radii, for the corresponding support members 31 to extend out, and the slot length is left with a margin; the rotary drive module 223 drives the gear 222 to rotate clockwise / counterclockwise, and the arc-shaped rack 221 meshing with the drive gear 222 drives the placement plate 21 to rotate counterclockwise / clockwise at a certain angle along the guide rail 42. The drive support member 31 is driven by the force of the sliding slots 211 and moves along the linear module 32, thereby being automatically adjusted to other positions.

[0042] The above-mentioned structure is designed to effectively support stator assemblies of different models by automatically adjusting the relative distance between the support components. The structure is also reasonably designed, using an annular placement disk that is driven to rotate along its edge.
