DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0029] like Figure 1 As shown, an embodiment of the present application provides a stator press-fitting mechanism, including a rotating mechanism 3, a positioning mechanism 1 and a press-fitting mechanism 2, the rotating mechanism 3 is used to transfer the sleeve 5 to the positioning mechanism 1, the positioning mechanism 1 positions the stator 4 and the sleeve 5, and the press-fitting mechanism 2 is used to press the stator 4 onto the sleeve 5.

[0030] like Figure 2 As shown, the positioning mechanism 1 includes a fixed frame 11, a first cylinder 12 that moves vertically, a positioning assembly 13 and a fixing assembly 14. The first cylinder 12 is installed on the fixed frame 11, and the driving end of the first cylinder 12 is connected to the positioning assembly 13. The first cylinder 12 is used to drive the positioning assembly 13 to press the firmware assembly.

[0031] like Figure 3 and Figure 6 As shown, the positioning assembly 13 includes a positioning component 131, an elastic pressure plate 132 and two guide columns 133. The elastic pressure plate 132 is installed on the positioning component 131 to press the sleeve 5. The two guide columns 133 are respectively installed at the bottom ends of the positioning component 131. The positioning component 131 is provided with a first through hole 001 for accommodating the stator 4 and the sleeve 5 and a plunger 002 for spacing the stator 4 and the sleeve 5. The first through hole 001 is provided with a step 007 for limiting the sleeve 5.

[0032] like Figure 4As shown, the fixing assembly 14 is provided with a groove 141 for accommodating the sleeve 5 and two second through holes 142 for positioning the guide column 133 , and the groove 141 is provided with a carrier 143 for accommodating the sleeve 5 .

[0033] Specifically, the stator pressing mechanism is composed of a rotating mechanism 3, a positioning mechanism 1 and a pressing mechanism 2. The sleeve 5 and the stator 4 are respectively transferred to the positioning mechanism 1 by the rotating mechanism 3 and the four-axis robot in the prior art. The positioning mechanism 1 positions the stator 4 and the sleeve 5, and then the stator 4 is pressed into the sleeve 5 by the pressing mechanism 2.

[0034] The rotating mechanism 3 transfers the sleeve 5 to the carrier 143 of the fixed component 14, and the four-axis robot transfers the stator 4 to the first through hole 001 of the positioning component 131. The first cylinder 12 of the positioning mechanism 1 drives the positioning component 131 to drive the elastic pressure plate 132 and the guide column 133 to move toward the carrier 143 of the fixed component 14. The two guide columns 133 extend into the through holes on both sides of the fixed component 14 respectively. The elastic pressure plate 132 presses the sleeve 5 on the carrier 143. The sleeve 5 passes through the elastic pressure plate 132 and extends into the first through hole 001 of the positioning component 131. The step 007 in the first through hole 001 limits the sleeve 5, and the sleeve 5 is coaxial with the stator 4. Since the lower end of the stator 4 is provided with a plunger 002, the stator 4 will not fall directly into the sleeve 5. Next, the press-fitting mechanism 2 presses the stator 4, and the plunger 002 moves backward under the force, so that the stator 4 is press-fitted into the sleeve 5. After the press-fitting is completed, the rotating mechanism 3 moves the press-fitted stator 4 out of the carrier 143 and transfers it to the conveying mechanism.

[0035] The mechanism positions the stator 4 and the sleeve 5 by the positioning component 131 and then presses them by the press-fitting mechanism 2, which greatly improves the yield rate of the finished product after press-fitting. The rotation mechanism 3, the positioning mechanism 1 and the press-fitting mechanism 2 cooperate with each other to improve the working efficiency of the equipment.

[0036] like Figure 7 As shown, in one of the embodiments, the pressing mechanism 2 of the stator pressing mechanism includes a base 21, a support frame 22, an electric cylinder 23 and a pressing head 24. A second cylinder 25 for horizontal movement is provided on the base 21. The driving end of the second cylinder 25 is connected to the support frame 22. The support frame 22 and the base 21 are slidably matched through a sliding assembly. The second cylinder 25 is used to drive the support frame 22 to move horizontally toward the positioning mechanism 1. The electric cylinder 23 is installed at the upper end of the support frame 22. The driving end of the electric cylinder 23 is connected to the pressing head 24. The pressing head 24 and the support frame 22 are slidably matched through a sliding assembly. The electric cylinder 23 is used to drive the pressing head 24 to press the stator 4 in the positioning component 131 into the sleeve 5.

[0037] Specifically, the second cylinder 25 drives the support frame 22 to drive the electric cylinder 23 and the pressure head 24 to move horizontally toward the positioning mechanism 1. After moving to one side of the positioning mechanism 1, the electric cylinder 23 drives the pressure head 24 to press the stator 4 in the positioning component 131, so that the stator 4 is pressed into the sleeve 5.

[0038] This arrangement facilitates pressing the stator 4 of the positioning component 131 , thereby press-fitting the stator 4 into the sleeve 5 .

[0039] like Figure 7 As shown, in one embodiment, the pressing head 24 of the stator pressing mechanism is configured as a column, and the diameter of the column is smaller than the diameter of the stator 4. This configuration facilitates the pressing head 24 to extend into the first through hole 001 of the positioning component 131 to press the stator 4.

[0040] like Figure 8 As shown, in one of the embodiments, the rotating mechanism 3 of the stator pressing mechanism includes a supporting frame 31 and a rotating assembly 32, and a third cylinder 33 for vertical movement is provided on the supporting frame 31, and a driving end of the third cylinder 33 is connected to the rotating assembly 32, and the rotating assembly 32 and the supporting frame 31 are slidably matched through a sliding assembly, and the third cylinder 33 is used to drive the rotating assembly 32 to load and unload materials to the positioning mechanism 1.

[0041] Specifically, the third cylinder 33 drives the rotating assembly 32 to move downward to place the sleeve 5 at one end in the carrier 143 of the fixed assembly 14, and the third cylinder 33 drives the rotating assembly 32 to move downward to grab the press-fitted stator 4 and move it to the conveying mechanism. This arrangement facilitates the loading and unloading operations of the sleeve 5 and the press-fitted product.

[0042] like Figure 8 As shown, in one embodiment, the rotating assembly 32 of the stator pressing mechanism includes a fixed frame 321, a rotating cylinder 322 and a fixed plate 323, the rotating cylinder 322 is installed on the fixed frame 321, the driving end of the rotating cylinder 322 is connected to the fixed plate 323, and the first cylinder clamp 324 and the second cylinder clamp 325 are symmetrically arranged on the fixed plate 323, the first cylinder clamp 324 is used to grab the sleeve 5, and the second cylinder clamp 325 is used to grab the pressed product.

[0043] Specifically, the rotating cylinder 322 rotates to drive the first cylinder clamp 324 on the fixed plate 323 to grab the sleeve 5, and then the rotating cylinder 322 rotates the first cylinder clamp 324 to the upper end of the carrier 143 of the fixed assembly 14, and the third cylinder 33 drives the fixed frame 321 to drive the first cylinder clamp 324 to move downward and release to place the sleeve 5 in the carrier 143. When the press-fitting is completed, the rotating cylinder 322 rotates to rotate the second cylinder clamp 325 to the top of the carrier 143, and the third cylinder 33 drives the fixed frame 321 to drive the second cylinder clamp 325 to move downward to grab the stator 4 that has been press-fitted on the carrier 143. The rotating cylinder 322 and the third cylinder 33 cooperate to rotate and transfer the stator 4 that has been press-fitted to the conveying mechanism. This arrangement facilitates the loading and unloading operations of the sleeve 5 and the stator 4 that has been press-fitted.

[0044] like Figure 5 As shown, in one embodiment, the elastic pressure plate 132 of the stator pressing mechanism includes a pressure plate 003, two bolts 004 and two springs 005 sleeved on the two bolts 004, the two bolts 004 respectively pass through the positioning component 131 to be connected to the pressure plate 003, one end of the two springs 005 respectively abuts on the positioning component 131, and the other ends of the two springs 005 respectively abut on the pressure plate 003, and the pressure plate 003 is provided with a third through hole 006 for the sleeve 5 to pass through.

[0045] Specifically, the pressure plate 003 of the elastic pressure plate 132 presses the carrier of the sleeve 5 , and the spring 005 plays a role of fixing and buffering the carrier of the sleeve 5 .

[0046] like Figure 2 As shown, in one embodiment, a first sensor 15 is provided at one end of the fixed frame 11 of the stator press-fitting mechanism close to the fixed assembly 14, and the first sensor 15 is used to detect whether the sleeve 5 in the carrier 143 is placed in place. This setting is convenient for reminding the staff to check the placement of the sleeve 5 in the carrier 143 in time.

[0047] like Figure 2 As shown, in one embodiment, a second sensor 16 is provided on the positioning component 131 of the stator press-fitting mechanism, and the second sensor 16 is used to detect whether the stator 4 is placed in place in the positioning component 131.
