[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] A multifunctional pressing device includes a base 1, on which a horizontal guide rail 2 is provided. A first loading plate 3 and a second loading plate 4 are slidably mounted on the horizontal guide rail 2. A first loading platform 5, a stator placement seat 7, a second loading platform 6, and an end plate placement seat 8 are provided on the first loading platform 3 and the second loading plate 4, respectively. The first loading platform 5, the stator placement seat 7, the second loading platform 6, and the end plate placement seat 8 are arbitrarily arranged on the first loading platform 3 and the second loading plate 4 without limitation. A housing fixing structure 9 is provided on the first loading platform 5, and a rotor fixing mechanism is provided on the second loading platform 6. A mounting frame 12 is provided above the base 1 via a support frame 11, on which a vertically mounted device is installed. There is a first cylinder 13, and a lifting frame 14 is provided below the mounting frame 12. The telescopic rod of the first cylinder 13 is fixedly connected to the lifting frame 14 with the extension rod facing downward. The support frame 11 includes four support rods provided on the base 1. The four support rods are distributed in a rectangular shape. Four guide sleeves matching the support rods are fixedly provided on the lifting frame 14. The four guide sleeves are respectively fitted onto the four support rods and slide. A moving plate 15 is slidably provided on the lifting frame 14. An end cap gripping mechanism and a pressing mechanism 17 are installed at the lower end of the moving plate 15. The first loading plate 3, the second loading plate 4 and the moving plate 15 are driven to move by conventional means, such as the push of the propulsion cylinder or the driving method of the cooperation of the rotary motor and the lead screw.

[0023] The housing is fixed on the housing fixing structure 9 with the opening of the housing facing upward. The stator is placed on the stator placement seat 7 and placed vertically. The rotor is placed vertically on the rotor fixing structure 10. The end plate of the rotor is placed horizontally on the end plate placement seat 8 (in the prior art, the end plate needs to be installed on the rotor). The end plate placement seat 8 is moved to the lower part of the moving plate 15 by the movement of the first loading plate 3 and the second loading plate 4. The first cylinder 13 drives the lifting frame 14 to descend and grabs the end plate from the end plate placement seat 8 through the end cover gripping mechanism. Then the rotor fixing seat with the rotor is moved to the lower part of the moving plate 15 and the end plate is installed on the rotor. The moving plate 15 is moved to grab the rotor through the pressing mechanism 17 and the stator is moved to the lower part of the moving plate 15. The rotor is pressed into the stator through the pressing mechanism 17. The rotor is then grabbed by the pressing mechanism 17 and the stator and rotor are lifted together. Finally, the housing is moved to the lower part of the moving plate 15 and the pressing mechanism 17 presses the assembled stator and rotor into the housing together. This invention enables the assembly of the housing, stator, and rotor at the same workstation, thereby increasing work efficiency.

[0024] In a preferred embodiment, the housing fixing structure 9 includes a plurality of vertically arranged first support columns 18 and a plurality of second support columns 19 arranged in a circle. A vertically arranged second cylinder is provided inside the second support column 19. The telescopic rod of the second cylinder is arranged upward, and a first pressure block 20 is rotatably provided at the end of the telescopic rod of the second cylinder.

[0025] Several first support columns 18 are placed against the lower end of the housing. The second cylinder raises the first pressure block 20, then rotates one end of the first pressure block 20 to the top of the housing. The second cylinder lowers the first pressure block 20, and the housing is fixed by pressing the first pressure block 20 against the upper end of the housing.

[0026] In a preferred embodiment, the rotor fixing structure 10 includes a mounting base 23, the upper end of which is provided with mounting holes that match the stator.

[0027] Insert the rotor vertically into the mounting hole.

[0028] In a preferred embodiment, the stator placement base 7 includes a first column, the upper end of which is provided with a plurality of support blocks 22 arranged in a circle. The inner wall of the support block 22 is arranged in an arc shape that matches the outer wall of the stator. The diameter of the circle formed by the inner walls of the plurality of support blocks 22 is the same as the diameter of the outer wall of the stator. A support block for supporting the stator is fixed on the inner wall of the support block 22. The height of the support block is lower than the upper end of the support block 22.

[0029] The stator is placed vertically on several support blocks and is limited by several support blocks 22.

[0030] In a preferred embodiment, the end plate placement seat 8 includes a second column, the upper center of which has a limiting post 25 that matches the center hole of the end plate.

[0031] The end plate has a central hole. The end plate is placed horizontally on the upper end of the second column, and the limiting post 25 is inserted into the central hole.

[0032] In a preferred embodiment, the end cap gripping mechanism includes a first connecting seat 26 fixedly connected to the moving plate 15. A first gripping disc 27 is provided at the lower end of the first connecting seat 26. Three sliders 28 are slidably mounted on the lower surface of the first gripping disc 27 via a slide rail 30. The three sliders 28 form a circle with an included angle of 120° between each pair. A clamping block 29 is provided at the inner end of each slider 28. A pushing cylinder 31 mounted on the first gripping disc 27 is provided between every two sliders 28. The telescopic rod of the pushing cylinder 31 is arranged inwards and fixedly connected to a pushing block 32. Both ends of 32 are hinged to the sliders 28 on both sides by a drive link. The drive link includes a first link 33 and a second link 34. One end of the first link 33 is hinged to the push block 32, and the other end of the first link 33 is bent and extended toward the corresponding slider 28 to form the second link 34. The second link 34 is hinged to the slider 28. The angle between the first link 33 and the second link 34 is an obtuse angle and the angle between the first link 33 and the second link 34 faces inward. The connection between the first link 33 and the second link 34 is rotatably connected to the first gripper plate 27.

[0033] The first connecting seat 26 is moved above the end plate placement seat 8 and driven to descend by the first cylinder 13. This pushes the cylinder 31 to drive the push block 32 to move outward, causing the drive linkage to rotate. The end of the first linkage 33 that is hinged to the push block 32 rotates outward along with the push block 32, thereby causing the end of the second linkage 34 that is hinged to the slider 28 to move inward, thereby driving the slider 28 to slide inward. The three sliders 28 slide inward synchronously to clamp the end plate.

[0034] In a preferred embodiment, the inner end of the clamping block 29 is arranged in an arc shape that matches the end plate.

[0035] In a preferred embodiment, the pressing mechanism 17 includes a second connecting seat 35 fixedly connected to the movable plate 15. A pressing head 36 is rotatably provided at the lower end of the second connecting seat 35. The pressing head 36 has a through hole 37 at its center. A sliding hole 38 communicating with the through hole 37 is vertically provided inside the second connecting seat 35. A triangular pneumatic claw 39 is movably provided at the through hole 37. A sliding rod 40 extending into the sliding hole 38 is provided at the upper end of the triangular pneumatic claw 39. A limiting slider 41 matching the sliding hole 38 is fixedly provided on the sliding rod 40. A limiting edge protrudes from the inner wall of the sliding hole 38. The limiting edge is located below the limiting slider 41. A buffer spring 42 is sleeved on the sliding rod 40. The buffer spring 42 is located below the limiting edge. The lower end of the buffer spring 42 is fixedly connected to the sliding rod 40, and the upper end of the buffer spring 42 is fixedly connected to the inner wall of the sliding hole 38.

[0036] The triangular pneumatic gripper 39 is used to grip the rotor and insert it into the stator. Then, the rotor is clamped and the rotor and stator are inserted into the housing together. When pressing down, the end face of the pressure head 36 presses on the upper end of the stator to press the stator into the housing. Due to the setting of the buffer spring 42, the triangular pneumatic gripper 39 retracts inward during the pressing of the stator to avoid excessive pressing of the rotor.
