[0061] The following is combined with Figure 2-11 The present application is further described.

[0062] Example 1

[0063] Reference Figure 2 , Figure 3 and Figure 4 The present application provides a press-fitting head for press-fitting a motor flange and a stator, which has a main axis 100 and a first direction Z parallel to the main axis 100, and the press-fitting head is used to press-fit the motor flange 200 onto the stator 300 along the first direction Z. The press-fitting head includes a bracket assembly 1, and a clamping assembly 2, an adjustment assembly 4, and a positioning assembly 3 arranged on the bracket assembly 1. Among them, the bracket assembly 1 includes a top plate 12, a connecting column 13, and a press-fitting base plate 11, which are sequentially arranged at intervals along the first direction Z, and the top plate 12 and the press-fitting base plate 11 are fixedly connected by the connecting column 13.

[0064] Reference Figure 3 , Figure 4 and Figure 5 The clamping assembly 2 includes a plurality of clamping jaws 21 arranged in a circle around the main axis 100 and a clamping drive source 22 for driving the clamping jaws 21 to move closer to or away from the main axis 100. In this embodiment, the clamping assembly 2 is configured as a three-jaw chuck, that is, three clamping jaws 21 are arranged around the main axis 100, the clamping drive source 22 is a cylinder or a hydraulic cylinder, the clamping drive source 22 is cylindrical, the axis of the clamping drive source 22 coincides with the main axis 100, and the clamping drive source 22 is fixedly connected to a side of the top plate 12 close to the press-fit substrate 11.

[0065] Reference Figure 2-Figure 4 The adjustment assembly 4 includes an adjustment plate 41 rotatably sleeved on the outer wall of the clamping drive source 22 and an adjustment drive source 42 for driving the adjustment plate 41 to rotate around the main axis 100. Specifically, in this embodiment, a fixed block 1b is fixedly provided on one side of the press-fit substrate 11 close to the top plate 12, and the adjustment drive source 42 is configured as a cylinder. One end of the adjustment drive source 42 is hingedly provided on the fixed block 1b, and the other end of the adjustment drive source 42 is hingedly provided on the adjustment plate 41. When the position of the adjustment plate 41 needs to be adjusted, the adjustment drive source 42 is started to drive the adjustment plate 41 to rotate. To this end, an arc-shaped hole 411 is provided on the adjustment plate 41 for the connection column 13 to pass through so as to avoid interference from the connection column 13 when the adjustment plate 41 rotates.

[0066] Reference Figure 3 , Figure 4 and Figure 6 The positioning assembly 3 is arranged on the press-fit substrate 11. The positioning assembly 3 includes a main body 31 and a positioning pin 32 which is telescopically arranged on the main body 31. The main body 31 is fixedly arranged on the adjustment plate 41 and the positioning pin 32 is arranged in the first direction Z pointing to the press-fit substrate 11. The positioning pin 32 is plugged and matched with the first hole 202 and the second hole 301 to realize the positioning function. The above setting enables the positioning assembly 3 to be movably arranged on the press-fit substrate 11 in the circumferential direction around the main axis 100. The press-fit substrate 11 is provided with an avoidance hole 11a for the positioning pin 32 to pass through.

[0067] Reference Figure 3 and Figure 4 There are three positioning components 3, and the size of the positioning pin 32 corresponding to each positioning component 3 is different. There are three positioning pins 32 corresponding to the avoidance hole 11a. Multiple positioning components 3 can be set on the adjustment plate 41 at the same time. When facing the first hole 202 and the second hole 301 with different apertures, positioning can be performed by replacing the positioning pins 32 of different sizes to achieve better adaptation, thereby improving the applicability of the press-fitting head.

[0068] Reference Figure 5In this embodiment, each clamping jaw 21 includes a limiting portion 211 parallel to the first direction Z and a bearing portion 212 fixed on the limiting portion 211 for bearing the motor flange 200 , and the bearing portion 212 extends in a direction perpendicular to the main axis 100 . A clamping hole 11b is provided at the center of the press-fit substrate 11 for three clamping jaws 21 to pass through simultaneously. The clamping drive source 22 drives the three clamping jaws 21 to move closer to or away from the main axis 100. When the motor flange 200 needs to be clamped, the press-fitting head moves to the top of the motor flange 200 so that the main axis 100 coincides with the axis of the motor flange 200. The clamping jaws 21 follow the press-fitting head to move downward and finally the clamping jaws 21 pass through the center hole 201 of the motor flange 200. The clamping drive source 22 drives the clamping jaws 21 to expand outward until the limiting portion 211 abuts against the inner wall surface of the center hole 201 of the motor flange 200, and the bearing portion 212 abuts against the side of the motor flange 200 that is away from the press-fit substrate 11 in the first direction Z. At this time, the clamping assembly 2 clamps the motor flange 200 and enables the motor flange 200 to rotate around the main axis 100 when clamping the motor flange 200, so as to facilitate the subsequent adjustment of the position of the motor flange 200.

[0069] According to the above setting, when multiple clamping jaws 21 clamp the motor flange 200, the motor flange 200 contacts the bearing portion 212 on one side in the first direction Z, and the peripheral side of the motor flange 200 contacts the limiting portion 211 so that the motor flange 200 can rotate while being clamped, and the positioning component 3 can pass through the press-fitting substrate 11 through the avoidance hole 11a to be plugged and matched with the first hole 202, thereby ensuring the position stability of the motor flange 200 during the clamping process; by adjusting the driving source 42, the positioning component 3 can be driven to move, thereby driving the motor flange 200 to rotate so that the first hole 202 of the motor flange 200 is aligned with the second hole 301 on the stator 300, until the positioning pin 32 passes through the first hole 202 and the second hole 301 at the same time to finally complete the alignment of the motor flange 200 and the stator 300, ensuring the accuracy of the alignment of the stator 300 and the motor flange 200 to improve the press-fitting quality.

[0070] It should be noted that, in this embodiment, the clamping jaws 21 extend from the central hole 201 of the motor flange 200 for clamping, which does not exclude that in other optional embodiments, the clamping jaws 21 clamp the outer wall surface of the motor flange 200 to clamp the motor flange 200.

[0071] Reference Figure 6The positioning component 3 is configured as a pin clamping cylinder, and its specific structure is as follows: a cavity 311 is provided inside the main body 31 of the positioning component 3, a positioning cylinder 33 is fixedly provided at one end of the main body 31, a piston rod of the positioning cylinder 33 extends into the cavity 311 and is driven by the positioning cylinder 33 to reciprocate along the axis of the cavity 311, an elastic member 34 is provided at the end of the piston rod of the positioning cylinder 33, a slot is provided at one end of the positioning pin 32 facing the elastic member 34, and the elastic member 34 is clamped in the slot.

[0072] This solution has the following obvious advantages, which are explained below in conjunction with the working principle.

[0073] First, the material picking process is that the press-fitting head is first moved to the top of the motor flange 200, and the positioning cylinder 33 is used to push the elastic member 34 to move outward along the axis of the cavity 311, pushing the positioning pin 32 to extend until the part of the positioning pin 32 exceeds the side of the press-fitting substrate 11 away from the top plate 12 in the first direction Z; then the press-fitting head moves downward, if the positioning pin 32 is not coaxial with the first hole 202, then the positioning pin 32 stops moving downward until it abuts against the surface of the motor flange 200, and the elastic member 34 is compressed; then the adjustment drive source 42 is started to drive the adjustment plate 41 to rotate and then drive the positioning assembly 3 to rotate until the positioning pin 32 is plugged into the first hole 202. At this time, the accurate positioning of the motor flange 200 is completed, and the motor flange 200 is ensured not to move during the subsequent transfer process of the motor flange 200.

[0074] The second point is that during the press-fitting process with the stator 300, the locating pin 32 needs to exceed the side of the motor flange 200 away from the press-fitting substrate 11 in the first direction Z, and the press-fitting head drives the motor flange 200 to move to the top of the stator 300, and the press-fitting head moves down until the locating pin 32 abuts against the surface of the stator 300 and stops. At this time, the first hole 202 and the second hole 301 are not coaxially positioned. At this time, the adjustment drive source 42 is started to drive the adjustment plate 41 to rotate, thereby driving the positioning assembly 3 to rotate. Since the clamping jaws 21 are arranged in a circle along the main axis 100 and the limiting portion 211 and the bearing portion 212 of the clamping jaws 21 are set, the clamping assembly 2 can still rotate the motor flange 200 around the main axis 100 when clamping the motor flange 200. At this time, the locating pin 32 is inserted in the first hole 202, and the rotation of the positioning assembly 3 drives the motor flange 200 to rotate together until the locating pin 32 is plugged into the second hole 301 to complete the positioning process of the motor flange 200 and the stator 300.

[0075] The stator 300 and the motor flange 200 can be automatically positioned during the material removal process and the pre-pressing process, which greatly improves the degree of automation and positioning accuracy.

The press-fitting device also includes a docking mechanism 8, which includes a docking bracket 81, a docking platform 82 that moves on the docking bracket 81 along the third direction Y, and a docking driving source 83 for driving the docking platform 82 to move.

In this embodiment, the docking drive source 83 is configured as a telescopic cylinder, the cylinder body of the telescopic cylinder is fixedly connected to the docking platform 812, and the piston rod of the telescopic cylinder is fixedly connected to the docking slide rail 813. When in use, the piston rod of the telescopic cylinder drives the docking slide rail 813 to move along the third direction Y, thereby driving the docking platform 82 to reciprocate along the third direction Y.

This setting allows the motor flange 200 to be further limited in position during the transfer process to ensure the position accuracy of the clamping process. The docking platform 82 has at least two position states, namely, the material receiving position and the press-fitting position; wherein, in the press-fitting position, the docking platform 82 is located at one end of the press-fitting head in the first direction Z so that the main axis 100 coincides with the axis of the motor flange 200.
