Description

Technical Field

[0001] The utility model relates to the technical field of motor manufacturing, in particular to a press-fit rotor tooling. Background Art

[0002] The existing rotor core and shaft are fastened by interference fit between the containing part (the shaft hole on the rotor core) and the contained part (the shaft). The tooling in the prior art can achieve interference fit between the shaft and the shaft hole by positioning the rotor core with the shaft hole and then inserting the shaft into the shaft hole.

[0003] like Figure 1 As shown, the rotor core in the prior art is provided with a magnetic steel slot. After the rotor core and the shaft are assembled, the magnetic steel is installed in the secondary steel slot, and then the magnetic steel is magnetized. During magnetization, another tool is used to clamp the shaft, and a preset angle is formed between the magnetic steel and the magnetic field. To facilitate positioning of the rotor core, two oppositely arranged flat slots are provided at the end of the shaft. By clamping the bottom of the flat slot with a tool, the rotor core can be positioned, and a preset angle is formed between the rotor core and the magnetic field.

[0004] The tooling of the prior art can only transfer the shaft to the rotor core, but cannot achieve the relative positioning of the shaft and the rotor core in the circumferential direction. This results in that when the slot bottom of the shaft is clamped by another tooling, the rotor core and the magnetic field cannot form a preset angle. Utility Model Content

[0008] An axis positioning mechanism is connected to the mounting frame and is located at the lower side of the first axis hole. The axis positioning mechanism includes a mounting portion, a driving member, and a first slider and a second slider arranged opposite to each other. The mounting portion is provided with a second axis hole that matches the axis clearance. The first slider and the second slider can be relatively slidably connected to the mounting portion.

[0017] Optionally, the mounting frame further comprises a step adjustment hole connected to the mounting space, and the press-fit rotor tooling further comprises an adjustment bolt, which can pass through the step adjustment hole and be threadedly connected to the shaft positioning mechanism, and the nut of the adjustment bolt can abut against the step surface of the step adjustment hole.

[0018] Optionally, the press-fit rotor tooling further includes a base, the lower end of the mounting frame is connected to the base, a third axial hole is formed on the base, and the shaft can be inserted into the third axial hole.

[0019] Optionally, a positioning groove is provided at the top of the mounting frame, the positioning groove is connected to the first axial hole, the positioning protrusion is arranged at the bottom of the positioning groove, and the rotor core can be arranged in the positioning groove.

[0020] As can be seen from the above, the technical solution provided by the utility model is that the rotor core can be arranged at the top of the mounting frame, so that the rotor core is supported by the mounting frame, and the rotor core will not move in the axial direction when the shaft is assembled.

If the first slider and the second slider cannot abut against the bottom of the flat slot, the shaft can be rotated so that the first slider and the second slider can abut against the bottom of the flat slot respectively, thereby realizing the positioning of the shaft in the circumferential direction. Since the positions of the shaft and the rotor core in the circumferential direction are respectively positioned, the relative positions of the shaft and the rotor core in the circumferential direction are also positioned.

[0022] When the shaft is pressed by a press or the like, the shaft slides downward between the shaft hole of the rotor core, the first shaft hole, the second shaft hole, and the first slider and the second slider until it is assembled into place.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] like Figure 1 As shown, the press-fit rotor tooling provided in this embodiment can be used to assemble the shaft 100 into the rotor core 200, wherein the part of the shaft 100 that cooperates with the rotor core 200 is the assembly section 101, and the assembly section 101 and the shaft hole of the rotor core 200 are interference fits. Below the assembly section 101, the diameter of the shaft 100 is smaller than the diameter of the rotor core 200, and can easily pass through the shaft hole. The press-fit rotor tooling provided in this embodiment can fix the rotor core 200, and then insert the part below the assembly section 101 into the shaft hole. At the same time, the press-fit rotor tooling can realize the relative positioning of the rotor core 200 and the shaft 100 in the circumferential direction. Finally, the upper end of the shaft 100 is forced by a press, and the shaft 100 is further pressed into the shaft hole, that is, the assembly section 101 is inserted into the shaft hole.

[0043] Specifically, this embodiment provides a press-fit rotor tooling for assembling the rotor core 200 and the shaft 100 to improve the positioning accuracy between the shaft 100 and the rotor core 200 , including the positioning of the relative circumferential position between the shaft 100 and the rotor core 200 .

[0044] like Figure 2 and Figure 3 As shown, the press-fit rotor tooling provided in this embodiment includes a mounting frame 1 and a shaft positioning mechanism 2. At least one positioning protrusion 11 is provided at the top of the mounting frame 1. The mounting frame 1 is provided with a first shaft hole 13. The rotor core 200 can be provided at the top of the mounting frame 1, so that the rotor core 200 is supported by the mounting frame 1. When the shaft 100 is assembled, the rotor core 200 will not move in the axial direction. A positioning protrusion 11 can be inserted into a magnetic steel slot 201 of the rotor core 200, so as to realize the positioning of the rotor core 200 in the circumferential direction. At the same time, when the shaft 100 is assembled, the rotor core 200 will not move in the circumferential direction. In this embodiment, two positioning protrusions 11 are provided, and each positioning protrusion 11 corresponds to a magnetic steel slot 201.

[0045] The shaft positioning mechanism 2 is connected to the mounting frame 1 and is located at the lower side of the first shaft hole 13 . After the shaft 100 passes through the shaft hole of the rotor core 200 , it can pass through the first shaft hole 13 and enter the shaft positioning mechanism 2 .

[0046] like Figure 4 and Figure 5 As shown, the shaft positioning mechanism 2 includes a mounting portion, a driving member, and a first slider 22 and a second slider 23 arranged opposite to each other. The mounting portion is provided with a second shaft hole 21 which is clearance-matched with the shaft 100. The first slider 22 and the second slider 23 can be relatively slidably connected to the mounting portion. The shaft 100 can pass through the first shaft hole 13 and the second shaft hole 21 and be clamped between the first slider 22 and the second slider 23. The first slider 22 can abut against a groove bottom 104 of the shaft 100, and the second slider 23 can abut against another groove bottom 104 of the shaft 100. The driving member can drive the first slider 22 and the second slider 23 to clamp the shaft 100.

[0047] When the shaft 100 is assembled to the rotor core 200, the shaft 100 passes through the shaft hole, the first shaft hole 13, the second shaft hole 21, and between the first slider 22 and the second slider 23 of the rotor core 200 in sequence. When the first slider 22 and the second slider 23 respectively abut against the bottom 104 of the flat groove 103, the surface shaft 100 is accurately positioned in the circumferential direction. If the first slider 22 and the second slider 23 cannot abut against the bottom 104 of the flat groove 103, the shaft 100 can be rotated so that the first slider 22 and the second slider 23 can abut against the bottom 104 of the flat groove 103 respectively, thereby realizing the positioning of the shaft 100 in the circumferential direction. Since the positions of the shaft 100 and the rotor core 200 in the circumferential direction are respectively positioned, the relative positions of the shaft 100 and the rotor core in the circumferential direction are also positioned.

[0048] Since the second axial hole 21 on the mounting portion is clearance-fitted with the shaft 100, and at the same time, during assembly, the assembly section 101 of the shaft 100 is interference-fitted with the rotor core 200, and the second axial hole 21 is located below the rotor core 200, the rotor core 200 and the second axial hole 21 position the shaft 100 in the up and down directions to prevent the shaft 100 from shifting during the assembly process, thereby ensuring that the shaft 100 and the rotor core 200 are coaxial after assembly.

[0049] When the shaft 100 is pressed by a press, the shaft 100 slides downward between the shaft hole of the rotor core 200, the first shaft hole 13, the second shaft hole 21, the first slider 22 and the second slider 23 until it is assembled in place. In this embodiment, the mounting frame 1 can prevent the rotor core 200 from moving in the axial direction, the positioning protrusion 11 can realize the positioning of the rotor core 200 in the circumferential direction and prevent the rotor core 200 from moving in the circumferential direction, the first slider 22 and the second slider 23 can realize the positioning of the shaft 100 in the circumferential direction, and the shaft hole of the rotor core 200 and the second shaft hole 21 can prevent the shaft 100 from being offset, thereby ensuring that the shaft 100 is accurately assembled to the rotor core 200.

[0050] like Figure 2 As shown, preferably, a positioning groove 12 is provided at the top of the mounting frame 1, the positioning groove 12 is communicated with the first shaft hole 13, the positioning protrusion 11 is arranged on the bottom surface of the positioning groove 12, and the rotor core 200 can be arranged in the positioning groove 12. The positioning groove 12 facilitates the operator to determine the placement position of the rotor core 200, and is convenient for user operation.

[0051] like Figure 5-Figure 7 As shown, the mounting portion includes a positioning cover plate 26 and a box body 27, the positioning cover plate 26 is detachably covered on the box body 27, the second shaft hole 21 is opened in the positioning cover plate 26, and the first slider 22 and the second slider 23 are slidably arranged on the box body 27, so as to facilitate the installation of the first slider 22 and the second slider 23. Optionally, the positioning cover plate 26 and the box body 27 are connected by a connecting member such as a fixing bolt 20.

[0052] like Figure 4-Figure 6 As shown, the driving member includes a first spring 24 and a second spring 25. The first spring 24 is disposed between the mounting portion and the first slider 22 to drive the first slider 22 to move toward the side where the second slider 23 is located. The second spring 25 is disposed between the mounting portion and the second slider 23 to drive the second slider 23 to move toward the side where the first slider 22 is located. The spring drives the first slider 22 and the second slider 23 to sandwich the shaft 100, so that the shaft 100 can slide conveniently between the first slider 22 and the second slider 23, and it is also convenient to position shafts 100 of different sizes.

[0053] The first slider 22 is provided with a first blind hole 221 for accommodating the first spring 24. One end of the first spring 24 extends out of the first blind hole 221, so that one end of the first spring 24 abuts against the box body 27, and the other end of the first spring 24 abuts against the bottom of the first blind hole 221, so that the first spring 24 drives the first slider 22 to slide toward the side where the second slider 23 is located.

[0054] The second slider 23 is provided with a second blind hole 231 for accommodating the second spring 25. One end of the second spring 25 extends out of the second blind hole 231, so that one end of the second spring 25 abuts against the box body 27, and the other end of the second spring 25 abuts against the bottom of the second blind hole 231, so that the second spring 25 drives the second slider 23 to slide toward the side where the first slider 22 is located.

[0055] Of course, the arrangement of the first spring 24 and the second spring 25 is not limited to this. One end of the first spring 24 can also be fixedly connected to the inner wall of the box body 27, and the other end can be fixedly connected to the first slider 22, and one end of the second spring 25 can be fixedly connected to the inner wall of the box body 27, and the other end can be fixedly connected to the second slider 23.

[0056] like Figure 5 As shown, in order to facilitate the insertion of the shaft 100 between the first slider 22 and the second slider 23, optionally, the first slider 22 and the second slider 23 are each provided with a guide slope 232 on the side close to each other, and from the side close to the second shaft hole 21 to the side away from the second shaft hole 21, the two guide slopes 232 are inclined toward the side close to each other.

[0057] Preferably, the surfaces of the first sliding block 22 and the second sliding block 23 that contact the groove bottom 104 of the flat groove 103 are planes, and the groove bottom 104 is also a plane, so as to better position the shaft 100 .

[0058] like Figure 6 As shown, the installation portion is provided with a guide space 28. Specifically, the box body 27 is a hollow structure. After the positioning cover plate 26 is covered on the box body 27, the guide space 28 can be enclosed. The first slider 22 and the second slider 23 are slidably arranged in the guide space 28. Figure 7 As shown, the bottom and side of the first slider 22 and the second slider 23 are both provided with guide protrusions 233 , and the guide protrusions 233 can contact the bottom wall or the side wall of the guide space 28 to guide the sliding of the first slider 22 and the second slider 23 .

[0059] The guide protrusion 233 guides the first slider 22 or the second slider 23, reducing the contact area between the first slider 22 and the second slider 23 and the bottom wall and the side wall of the guide space 28, that is, reducing the contact area between the first slider 22 and the second slider 23 and the positioning cover plate 26 and the inner wall of the box body 27, so that the first slider 22 and the second slider 23 can move more smoothly.

[0060] like Figure 5 As shown, optionally, a fourth axial hole 271 can be opened on the bottom wall of the box body 27 to allow the shaft 100 to pass through the box body 27. Of course, in other optional embodiments, the height of the box body 27 can also be designed to be larger to accommodate the lower end of the shaft 100 through the box body 27.

[0061] Optionally, the press-fit rotor tool further includes a base 3, the lower end of the mounting frame 1 is connected to the base 3, a third shaft hole 31 is provided on the base 3, and the shaft 100 can be passed through the third shaft hole 31. The bottom surface area of ​​the base 3 is larger than the lower end area of ​​the mounting frame 1 to ensure that the press-fit rotor tool is stably placed.

[0062] like Figure 4 and Figure 5 As shown, when the shaft 100 is installed in place, it can pass through the shaft hole of the rotor core 200, the first shaft hole 13, the second shaft hole 21, between the first slider 22 and the second slider 23, the fourth shaft hole 271 and the third shaft hole 31 in sequence.

[0063] like Figure 4 As shown, the shaft shoulder 102 of the shaft 100 can abut against the positioning cover plate 26. Specifically, when the shaft 100 is assembled in place, the shaft shoulder 102 abuts against the positioning cover plate 26, thereby facilitating the determination that the shaft 100 is pressed into place.

[0064] In order to make the press-fit rotor tooling adapt to shafts 100 of different lengths, that is, when the positions of the shaft shoulders 102 of each shaft 100 are different, the press-fit rotor tooling can determine whether the shaft 100 is pressed into place. Optionally, the shaft positioning mechanism 2 is adjustably connected to the mounting frame 1 to be close to or away from the first shaft hole 13.

[0065] The specific position of the shaft positioning mechanism 2 is determined by the position of the shaft shoulder 102 when the shaft 100 is assembled in place, that is, when the shaft 100 is assembled in place, the shaft shoulder 102 just abuts against the shaft positioning mechanism 2. For example, when the position of the shaft shoulder 102 is relatively high, the position of the shaft positioning mechanism 2 can be adjusted upward (in the direction close to the first shaft hole 13) so that when the shaft 100 is installed in place, the shaft shoulder 102 can abut against the positioning cover plate 26 of the shaft positioning mechanism 2; on the contrary, when the position of the shaft shoulder 102 is relatively low, the position of the shaft positioning mechanism 2 can be adjusted downward (in the direction away from the first shaft hole 13) so that when the shaft 100 is installed in place, the shaft shoulder 102 can abut against the positioning cover plate 26 of the shaft positioning mechanism 2.

[0066] like Figure 2 and Figure 8 As shown, the mounting frame 1 is provided with a mounting space 16, and the shaft positioning mechanism 2 is adjustably arranged in the mounting space 16, so that the structure of the press-fit rotor tooling is compact.

[0067] like Figure 2 and Figure 8 As shown, in order to facilitate the fixing of the shaft positioning mechanism 2, the mounting frame 1 is further provided with a step adjustment hole 15 connected to the mounting space 16, and the press-fit rotor tooling also includes an adjustment bolt 29, which can pass through the step adjustment hole 15 and be threadedly connected to the shaft positioning mechanism 2, and the nut of the adjustment bolt 29 can abut against the step surface 151 of the step adjustment hole 15. Figure 6 As shown, specifically, a threaded hole 272 may be opened on the box body 27 , and the adjusting bolt 29 is threadedly connected to the threaded hole 272 .

[0068] The working process of the press-fit rotor tooling provided in this embodiment is as follows:

[0069] According to the position of the shaft shoulder 102 of the shaft 100, the position of the shaft positioning mechanism 2 is adjusted;

[0070] Place the rotor core 200 in the positioning groove 12, and insert the positioning protrusion 11 into the magnetic steel groove 201;

[0071] The shaft 100 is inserted between the rotor core 200, the first shaft hole 13, and the first slider 22 and the second slider 23;

[0072] Determine whether the groove bottom 104 abuts against the first slider 22 and the second slider 23. If so, it means that the shaft 100 is inserted in place. If not, rotate the shaft 100 so that the groove bottom 104 abuts against the first slider 22 and the second slider 23.

[0073] The shaft 100 is pressed down by a press or the like until the shaft shoulder 102 abuts against the positioning cover plate 26 , thereby completing the assembly of the shaft 100 and the rotor core 200 .

[0074] Although the utility model has been described in detail above by means of general description, specific implementation methods and tests, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
