Description

Technical Field

DETAILED DESCRIPTION

[0068] The present invention will be further described below in conjunction with specific embodiments:

[0069] A motor press-fitting device comprises a press-fitting device and a workpiece positioning device, and is used for press-fitting a fan blade 11, a barrel 12, a rotor 13 and an end cover 14 of a motor 1.

[0070] like Figure 1-2 As shown, the motor 1 of this embodiment includes a fan blade 11, a barrel 12, a rotor 13, and an end cap 14. The rotor 13 is provided with bearings at both the front and rear ends. During installation, the rear end of the rotor 13 needs to pass through the end surface of the barrel 12 and the fan blade 11, and the rear end bearing is mounted on the end surface of the barrel 12. The front end of the rotor 13 needs to be fitted with an end cap 14, and the front end bearing is mounted on the end cap 14. In addition, the front end of the rotor 13 needs to be equipped with a corresponding accessory, typically a pulley 15 or a motor nut, depending on the purpose of the motor.

[0071] The fan blade 11 includes a disc-shaped fan blade body 111, blades 113 circumferentially arranged on the fan blade body 111, an axis mounting portion 112 arranged in the middle of the fan blade body 111 and used for mounting on one end of the rotor 13, and reinforcing ribs 114 arranged between the axis mounting portion 112 and two symmetrical blades 113.

[0072] At least one circumferential positioning protrusion 121 is extended from the front end side wall of the barrel 12, and at least one threaded hole is opened on the circumferential positioning protrusion 121. In this embodiment, three circumferential positioning protrusions 121 are provided, and each circumferential positioning protrusion 121 is provided with a threaded hole.

[0073] The end cover 14 is provided with mounting flanges corresponding to the circumferential positioning protrusions 121 around it, and the mounting flanges are provided with fixing holes 141 corresponding to the threaded holes. The fixing holes 141 are through holes. After the end cover 14 is crimped onto the barrel 12, the screws pass through the fixing holes 141 and are fixedly connected to the threaded holes to achieve fixed installation of the two.

[0074] like Figure 3-5 As shown, the workpiece positioning device includes a tooling base plate 91 , a barrel positioning unit 92 and an end cover positioning unit 93 .

[0075] The tooling base plate 91 is generally arranged on a turntable of a station switching device to facilitate its transportation to the corresponding processing station.

[0076] The barrel positioning unit 92 is provided on the tooling base plate 91 and is mainly used to position the barrel 12 and the fan blade 11 .

[0077] like Figure 4 As shown, the barrel positioning unit 92 includes a barrel positioning seat 921 , a plurality of barrel positioning pins 922 , a circumferential positioning member 923 and a fan blade positioning pin 925 .

[0078] The barrel locating seat 921 is disc-shaped and designed according to the barrel dimensions. It is first positioned on the tooling base plate 91 using two locating pins 94 and then secured using a seat fixing member 95, preferably a screw. The tooling base plate 91 is provided with a first pin hole corresponding to the locating pins 94 and a threaded fixing hole corresponding to the seat fixing member 95, facilitating installation of the barrel locating seat 921.

[0079] like Figure 5 As shown, the interior of the barrel positioning seat 921 defines a blade positioning cavity 924, within which are disposed a plurality of blade positioning pins 925 for positioning the blade 11. In this embodiment, two blade positioning pins 925 are provided, and the blade body 111 defines two blade positioning holes 115. The blade 11 is positioned by inserting the blade positioning pins 925 in the blade positioning cavity 924.

[0080] Preferably, the fan blade positioning cavity 924 is provided with a first avoidance portion 9241 for accommodating the shaft mounting portion 112 of the fan blade 11, a plurality of second avoidance portions 9242 for accommodating the blades 113 of the fan blade 11, and a third avoidance portion 9243 for accommodating the reinforcing ribs 114 of the fan blade 11. The third avoidance portion 9243 is arranged between the first avoidance portion 9241 and the two symmetrical second avoidance portions 9242. Since the assembled fan blade 11 has a shaft mounting portion 112, blades 113, and reinforcing ribs 114 protruding toward the same side, the present embodiment provides corresponding avoidance portions, each of which is a deep hole or groove of corresponding shape. When the fan blade 11 is placed in the fan blade positioning cavity 924, the shaft mounting portion 112, blades 113, and reinforcing ribs 114 enter the corresponding avoidance portions, thereby ensuring that the fan blade body 111 of the fan blade 11 can fully contact the bottom surface of the barrel positioning seat 921. When the rotor 13 and the fan blades 11 are press-fitted, the force-bearing area of ​​the fan blades 11 is increased, thereby effectively preventing the fan blades 11 from being deformed.

[0081] Second pinholes are distributed along the circumference of the barrel locating seat 921 according to the inner and outer diameters of the barrel 12. These second pinholes are provided with barrel locating pins 922. In this embodiment, three barrel locating pins 922 are provided, each spaced 120 degrees apart, and are positioned on the barrel locating seat 921 according to the outer diameter of the barrel 12.

[0082] Two circumferential positioning members 923 are provided, each having a strip-shaped hole formed therein and secured to the barrel positioning seat 921 by screws. The space between the two circumferential positioning members 923 accommodates any one of the circumferential positioning protrusions 121 of the barrel 12 for circumferential positioning of the barrel 12. In this embodiment, the gap between the two circumferential positioning members 923 can be adjusted through the strip-shaped hole, facilitating the accommodation of circumferential positioning protrusions 121 of varying widths to accommodate different barrel models.

[0083] Preferably, an end cap support portion 926 is provided between two adjacent second avoidance portions 9242. The end cap support portion 926 is an arc-shaped boss, and there are multiple end cap support portions 926, and their upper surfaces are all flush. The upper surface of the end cap support portion 926 and the upper surface of the fan blade positioning pin 925 contact the end face of the barrel 12 together. In this embodiment, the end face of the barrel 12 is flat, so the upper surface of the end cap support portion 926 and the upper surface of the fan blade positioning pin 925 are flush. When one end of the barrel 12 is mounted on the barrel positioning seat 921, the end cap support portion 926 supports the outer edge of the end face of the barrel 12, and the fan blade positioning pin 925 supports the center of the end face of the barrel 12. When the rotor is pressed, the center of the end face of the barrel 12 is supported by the fan blade positioning pin 925, and the edge of the end face of the barrel 12 is supported by the end cap support portion 926, which can effectively prevent the end face of the barrel 12 from deforming.

[0084] The outer ring of the end face of the barrel 12 is prone to burrs. In order to prevent the burrs from affecting the positioning, the outer ring of the end cover support part 926 is also provided with a flange avoidance part 927. The flange avoidance part 927 can be a complete annular groove, or an annular groove composed of several arc grooves, or an irregular groove that can accommodate the outer ring of the end face of the barrel 12.

[0085] like Figure 3 As shown, the end cap positioning unit 93 is provided on one side of the barrel positioning unit 92 for circumferential positioning of the end cap 14. When the end cap 14 is press-fitted, the end cap positioning unit 93 can guide the end cap 14 so that its fixing hole 141 can correspond to the threaded hole of the barrel 12.

[0086] The end cap positioning unit 93 comprises an end cap positioning seat 933 fixed to the tooling base 91, an end cap positioning frame 931, and an end cap positioning pin 932 vertically disposed on the end cap positioning frame 931. The end cap positioning frame 931 can be movably disposed on the end cap positioning seat 933 and adjusted in height to facilitate adaptation to barrels of different heights.

[0087] After the barrel 12 and the rotor 13 are installed in the workpiece positioning device, the end cover 14 is loaded. At this time, the guide hole 142 of the end cover 14 is aligned with the end cover positioning pin 932 and inserted, and then placed on the barrel 12 and the rotor 13.

[0088] The position of the end cover locating pin 932 and the position of the barrel locating seat 921 of this embodiment are both designed according to the size relationship of the motor 1. When the end cover 14 moves down along the end cover locating pin 932 and is pressed into the barrel 12, it can be ensured that the fixing hole 141 of the end cover 14 corresponds to the threaded hole of the barrel 12, which facilitates the tightening and fixing of the screws.

[0089] Preferably, the end cover positioning frame 931 has a vertical positioning rod and a horizontal pin mounting portion, one end of the pin mounting portion is fixed to one end of the positioning rod, and the other end is fixed to the end cover positioning pin 932. The end cover positioning pin 932 is vertically arranged, and the lower end is fixed to the pin mounting portion. Generally, the height of the pin mounting portion will be lower than the height of the circumferential positioning protrusion 121 of the barrel 12. In this way, when the end cover 14 is pressed, the end cover positioning unit 93 does not need to move up and down. Relying on the length of the end cover positioning pin 932, the end cover 14 is moved on the end cover positioning pin 932 and pressed. In addition, the end cover 14 of this embodiment is separately provided with a guide hole 142 for installing the end cover positioning pin 932, so that it will not affect the assembly of the screw. After assembly, it is only necessary to move the motor 1 upward and disengage it from the end cover positioning pin 932 before unloading.

[0090] The positioning rod is provided with a plurality of first adjustment holes 9311 at intervals. The adjusting fixing piece passes through the corresponding first adjustment holes 9311 to fix the end cap positioning frame 931 to the end cap positioning seat 933. The height of the end cap positioning frame 931 can be adjusted by adjusting the fixing piece to select different first adjustment holes 9311.

[0091] In addition, second adjustment holes 9331 are vertically opened on the two opposite side walls of the end cover positioning seat 933. The second adjustment hole 9331 is a long strip hole. The adjustment fixing part is a bolt and a fixing nut. The bolt passes through the second adjustment hole 9331 and the first adjustment hole 9311 in turn to realize the fixed connection between the end cover positioning frame 931 and the end cover positioning seat 933.

[0092] like Figure 6-7 As shown, the press-fitting device includes a press-fitting frame 51 , a press-fitting driving member 52 , a press-fitting frame 53 , a rotor press-fitting mechanism 54 , an end cover press-fitting mechanism 55 and a support unit 56 .

[0093] The press-fitting frame 51 includes a bottom plate, left and right side plates, a back plate and a top plate, which together form a frame structure with an open front side.

[0094] The press-fitting driving member 52 may be an electric cylinder, a pneumatic cylinder or a hydraulic cylinder, which is disposed at the upper end of the press-fitting frame 51 , namely the top plate row, for generating press-fitting power.

[0095] The press-fitting frame 53 comprises four press-fitting guide posts 534 movably mounted on the top plate, an upper press-fitting plate 532 positioned above the press-fitting guide posts 534, and a lower press-fitting plate 533 positioned below the press-fitting guide posts 534. The upper press-fitting plate 532 is a hollow plate positioned around the press-fitting driver 52, ensuring it is not interfered with by the driver 52 during movement and enabling the height of the press-fitting device to be controlled. The lower press-fitting plate 533 is connected to the telescopic end of the driver 52, enabling the press-fitting frame 53 to be raised and lowered via the driver 52.

[0096] In order to improve the quality of press-fitting, the press-fitting device of this embodiment realizes the stepwise press-fitting of the rotor 13 and the end cover 14 through a press-fitting driving member 52, first press-fitting the rotor 13 with the barrel 12 and the fan blades 11, and then press-fitting the end cover 14 with the rotor 13 and the barrel 12.

[0097] The end cover press-fitting mechanism 55 is provided on the press-fitting frame 53 and is located on the outer periphery of the rotor press-fitting mechanism 54 .

[0098] Specifically, the end cover pressing mechanism 55 includes an end cover pressing plate 551 , a plurality of columns 552 and an end cover pressing core 553 .

[0099] The end cover pressing plate 551 is fixed on the pressing frame 53 through a number of columns 552. A pressing core mounting hole is opened inside the end cover pressing plate 551, and the end cover pressing core 553 is fixed in the pressing core mounting hole. The shape of the end cover pressing core 553 is adapted to the outer ring of the end cover 14. The end cover pressing core 553 is made of wear-resistant material and has a C-shape or a ring shape.

[0100] In addition, the end cover pressure core 553 and the end cover pressing plate 55 can be set as one piece or as a separate piece, preferably as a separate piece. When the end cover pressure core 553 is worn, it is convenient to quickly replace the end cover pressure core 553 and reduce costs.

[0101] like Figure 8 As shown, the rotor press-fitting mechanism 54 is arranged in the middle of the press-fitting lower plate 533 of the press-fitting frame 53, and includes a rotor press-fitting sleeve 541 for rotor guidance, a rotor press-fitting core 542 for rotor press-fitting, and a press-fitting switching unit.

[0102] The rotor press sleeve 541 is fixed on the lower end surface of the press lower plate 533 of the press frame 53, and has an inlet 5414; the rotor press core 542 is movably arranged inside the rotor press sleeve 541 through a press spring 543, and the press switching unit is used to lock / release the positional relationship between the rotor press core 542 and the rotor press sleeve 541.

[0103] Specifically, the press-fit switching unit includes a switching driver 544 and a blocking member 545. The switching driver 544 is fixed to the press-fit frame 53 and is preferably a pneumatic cylinder. The blocking member 545 is a rectangular parallelepiped and is connected to the switching driver 544 to enable horizontal movement. A blocking hole 5413 is defined in the center of the rotor press-fit sleeve 541 for insertion of the blocking member 545.

[0104] After the blocking member 545 is inserted into the blocking hole 5413, when the press-fitting drive 52 drives the press-fitting frame 53 to press downward, the upper end of the rotor 13 first extends into the inlet 5414 and abuts against the rotor pressing core 542. The rotor pressing core 542 is blocked by the blocking member 545, that is, the rotor pressing core 542 is locked inside the rotor pressing sleeve 541. At this time, the rotor 13 can be pressed together with the barrel 12 and the fan blade 11. At this time, the end cover pressing mechanism 55 has not yet acted on the end cover 14. Subsequently, after the blocking member 545 leaves the blocking hole 5413, when the press-fitting drive 52 drives the press-fitting frame 53 to continue to press downward, the rotor pressing core 542 can move inside the rotor pressing sleeve 541 and will no longer generate downward pressure on the rotor 13. At this time, the end cover pressing mechanism 55 acts on the end cover 14 to press downward, completing the press-fitting with the rotor 13 and the barrel 12.

[0105] Specifically, the rotor press-fit sleeve 541 comprises an upper press-fit sleeve 5411 with the blocking hole 5413 and a lower press-fit sleeve 5412 with an inlet 5414, both of which are fixedly connected by screws. The upper press-fit sleeve 5411 is fixed to the press-fit lower plate 533. The rotor press core 542 comprises a press rod 5421 and a press-fit portion 5422. The outer diameter of the press-fit portion 5422 is larger than that of the press rod 5421, resulting in an inverted T-shaped cross-section of the rotor press core 542.

[0106] The upper press-fit sleeve 5411 defines an upper through-hole 5415 that mates with the press rod 5421. The lower press-fit sleeve 5412 defines a lower through-hole 5416 that mates with the press-fit portion 5422. The upper through-hole 5415 and the lower through-hole 5416 are coaxially arranged. The diameter of the upper through-hole 5415 is smaller than that of the lower through-hole 5416. The press-fit spring 543 is mounted on the press rod 5421 and abuts between the press-fit portion 5422 and the upper press-fit sleeve 5411. Under normal conditions, the press-fit spring 543 provides a force that forces the rotor press core 542 toward the inlet 5414.

[0107] Furthermore, the upper end of the rotor core 542 generally does not escape from the upper through-hole 5415. Specifically, when the rotor core 542 and the rotor press sleeve 541 are locked, a portion of the upper end of the rotor core 542 is within the upper through-hole 5415 and abuts the blocking member 545. This facilitates subsequent movement within the upper through-hole 5415 of the upper press sleeve 5411 after the lock is released, preventing it from becoming stuck. At this point, the lower end of the rotor core 542 precisely abuts the inlet 5414 of the lower press sleeve 5412, effectively controlling the length of the rotor press sleeve 541.

[0108] Because the blocking member 545 needs to transmit downward pressure during press-fitting of the rotor 13, the blocking hole 5413 radially extends through the upper press-fitting sleeve 5411 and the upper through-hole 5415 to enhance stability. When securing the rotor core 542, the blocking member 545 is inserted transversely throughout the upper press-fitting sleeve 5411. Both ends of the blocking member 545 are blocked by the upper press-fitting sleeve 5411. This prevents the blocking member 545 from deforming or shifting during press-fitting of the rotor 13, effectively ensuring the stable operation of the rotor core 542.

[0109] Preferably, a core avoidance hole 531 for the rotor core 542 is opened on the press-fitting frame 53 to facilitate the movement of the rotor core 542, thereby reducing the length of the rotor press-fitting sleeve 541 and making the structure compact.

[0110] like Figure 9As shown, the motor press-fitting equipment further includes a support unit 56 located below the workpiece positioning device, which has a support seat 561 , a support core 562 , a pushing member 563 and a pushing driving member 564 .

[0111] The support seat 561 is located below the turntable and the workpiece positioning device. A support core 562 is movably disposed within the support seat 561. The upper end of the support core 562 is used to contact the tooling base 91 of the workpiece positioning device. The lower end of the support core 562 is provided with an arc-shaped guide surface to facilitate the insertion of the push member 563.

[0112] The contact surface of the pushing member 563 is an inclined surface and contacts the lower end of the support core 562. The pushing driving member 564 is preferably a cylinder, which is used to provide power for the pushing member 563 to move.

[0113] When the press-fitting device needs to be press-fitted, the push-pull drive 564 pushes the push-pull member 563 to translate. Under the action of the inclined surface, the support core 562 moves upward, thereby abutting against the tooling base 91. This ensures the stability of the workpiece positioning device, prevents the turntable from tilting, and ensures the motor press-fitting effect. When the press-fitting is completed, the push-pull drive 564 drives the push-pull member 563 to return to its original position. The support core 562 falls under gravity and leaves the tooling base 91, ensuring that the workpiece positioning device can smoothly move to the next station.

[0114] Preferably, the support core 562 is movably arranged in the support seat 561 through the support spring 565, which can prevent gravity from failing and the support core 562 from falling automatically.

[0115] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
