Description

Technical Field

[0001] This application relates to the field of bearing assembly technology, and in particular to a bearing pressing machine for motor housings. Background Technology

[0002] With the continuous development of modern industry, the requirements for the precision of various equipment are gradually increasing. At the same time, the requirements for the vibration and noise of motors are also constantly increasing. In the existing technology, the motor has a housing, rotor, stator and motor shaft. The housing is composed of a shell and end cover. The motor shaft is set at the axis of the rotor, and the two ends of the motor shaft are rotatably supported on the shell and end cover. In order to ensure the flexible rotation of the motor shaft, an oil-impregnated bearing needs to be fixedly installed at the top center of the motor housing.

[0003] Currently, during the press-fitting of oil-impregnated bearings into the motor housing, the bearings placed in the pre-drilled holes in the motor housing are directly stamped. Due to the deviation in concentricity between the pre-drilled holes and the bearings, the fit between the bearings and the pre-drilled holes is poor, and in some cases, both the bearings and the motor housing are damaged during the pressing process, affecting product quality and reducing the product qualification rate. Utility Model Content

Each set of limiting discs 21 includes at least four limiting discs 21. The turntable device 20 is located between the telescopic positioning device 60 and the pressing device 50 along a preset direction. The telescopic positioning device 60 passes through the turntable device 20 and the limiting discs 21 on the turntable device 20 along the preset direction and is directly opposite the pressing device 50. Furthermore, the shaping device 30, the bearing conveying device 40, and the pressing device 50 are all distributed circumferentially along the turntable device 20. The device 40 and the pressing device 50 are respectively positioned opposite a limiting plate 21. The limiting plate 21 is provided with a limiting pin 211 inside, so as to realize the mutual cooperation between the limiting plate 21 and the limiting pin 211 and the outer wall of the motor housing 70 and the limiting hole 71 on the motor housing 70 to satisfy the position limitation of the motor housing 70 and the bearing 49 during the overall pressing process. The turntable device 20 is connected to an external power supply, signal sensor and automatic controller. Program code can be written according to actual needs to realize the automatic rotation of the turntable device 20.

Figure 7 As shown, the shaping device 30 includes a first bracket 31, a lifting and expanding mechanism 32 fixed to the first bracket 31, and a double-bar lifting and limiting mechanism 33. The lifting and expanding mechanism 32 is located between the double-bar lifting and limiting mechanisms 33 and can move freely up and down.

Figure 10 This is a perspective view of an inclined groove in a bearing pressing machine for motor housings, as described in this application.

The bearing sorting mechanism 42 includes a lifting tilting groove assembly 421 and a telescopic sorting assembly 422. The lifting tilting groove assembly 421 includes a lifting mechanism 4211 and a tilting groove 4212 connected to the lifting mechanism 4211. When the lifting mechanism 4211 descends, the tilting groove 4212 is in its initial position. When the lifting mechanism 4211 rises, the bearings 49 in the tilting groove 4212 slide along its tilting surface to the bearing conveying mechanism 43. Multiple bearings 49 are placed inside the tilting groove 4212. Specifically, the initial position of the tilting groove 4212 means that the groove opening 4212A of the tilting groove 4212 cooperates with the side wall of the bearing conveying mechanism 43 to restrict the bearings 49 inside the tilting groove 4212 and prevent the bearings 49 from sliding down the tilting surface of the tilting groove 4212.

[0058] Continue to refer to Figure 8 Please refer to them together. Figure 11 and Figure 12 , Figure 11 This is a structural diagram of the finishing plate and bearing conveying mechanism in a bearing pressing machine for motor housings according to this application. Figure 12 This is a schematic diagram of a bearing used in a bearing pressing machine for an electric motor housing, as described in this application. Figure 8 , Figure 11 and Figure 12 As shown, the telescopic sorting assembly 422 is mounted above the bearing conveying mechanism 43. Specifically, the telescopic sorting assembly 422 includes a telescopic mechanism 4221 and a sorting plate 4222 connected to the telescopic mechanism 4221. The telescopic mechanism 4221 is fixed to the second bracket 41. It should be noted that there is a gap L between the sorting plate 4222 and the bearing conveying mechanism 43, where L is less than the height H of the bearing 49. This allows the sorting plate 4222 and the telescopic mechanism 4221 to work together to clean the bearings 49 above the single-layer arrangement on the bearing conveying mechanism 43 through telescopic movement, and to allow the excess bearings 49 to fall into the inclined groove 4212. Multiple bearings 49 are placed inside the inclined groove 4212. With the cooperation of the lifting inclined groove assembly 421 and the telescopic sorting assembly 422, the bearings 49 are arranged in a single layer on the bearing conveying mechanism 43.

[0059] Continue to refer to Figure 8 and Figure 9 Please refer to them together. Figure 13 , Figure 13 yes Figure 8 An enlarged view of circle C shown. (See diagram below.) Figure 8 , Figure 9 and Figure 13 As shown, the bearing conveying mechanism 43 and the transfer propulsion mechanism 44 are connected by a transition component 47. The bearing conveying mechanism 43 is arranged along the X direction. The bearing conveying mechanism 43 includes a support frame 431, a conveyor belt 432 connected to the support frame 431, and a motor 433 connected to the conveyor belt 432. Furthermore, when the bearing 49 is placed on the transmission belt 432, the top surface of the support frame 431 and the top surface of the bearing 49 are at the same horizontal plane.

[0060] Continue to refer to Figure 9 The transfer propulsion mechanism 44 and the second support 41 are connected by a connecting plate 48. It should be noted that the shape of the connecting plate 48 includes, but is not limited to, L-shaped, H-shaped, etc.

[0061] Continue to refer to Figure 8 Please refer to them together. Figure 14 , Figure 14 This is another perspective view of the bearing conveying device in a bearing pressing machine for motor housings, as described in this application. Figure 8 and Figure 14 As shown, the transfer propulsion mechanism 44 includes a transfer platform 441 and a propulsion component 442 slidably connected to one end of the transfer platform 441. The transfer platform 441 is provided with a transfer groove 441A. The propulsion component 442 moves along the transfer groove 441A. The bottom of the transfer groove 441A is also provided with a discharge hole 441B. The discharge hole 441B corresponds to the bearing mounting position after the expansion hole of the motor housing 70. The transfer propulsion mechanism 44 is set along the Y direction. It should be noted that the discharge hole 441B corresponds to the bearing mounting position after the expansion hole of the motor housing 70 so that the bearing 49 falling through the discharge hole 441B can initially land at the bearing mounting position after the expansion hole of the motor housing 70.

[0062] Continue to refer to Figure 8 and Figure 9 A single-head lifting and limiting mechanism 45 is disposed on surface A of the transfer and propulsion mechanism 44. The single-head lifting and limiting mechanism 45 includes a lifting component 451 and a limiting head 452 connected to the lifting component 451. The lifting component 451 is fixedly connected to the propulsion component 442. The limiting head 452 corresponds to the discharge hole 441B, and the limiting head 452 can freely enter and exit the discharge hole 441B under the drive of the lifting component 451. When a bearing 49 passes through the discharge hole 441B, the limiting head 452 remains in contact with the circular plane of the bearing 49 during its descent until the bearing 49 falls into the bearing mounting position after the enlarged hole in the motor housing 70. Here, the limiting head 452 remains in contact with the circular plane of the bearing 49 during its descent until the bearing 49 falls into the bearing mounting position after the enlarged hole in the motor housing 70, thus preventing the bearing 49 from overturning during its descent and effectively improving reliability.

[0063] refer to Figure 15, Figure 15 This is a schematic diagram of the telescopic positioning device in a bearing pressing machine for motor housings, as described in this application. Figure 15 As shown, the telescopic limiting mechanism 46 is disposed on the B side of the transfer propulsion mechanism 44. The telescopic limiting mechanism 46 includes a telescopic component 461 and a limiting drag 462 connected to the telescopic component 461. The limiting drag 462 corresponds to the discharge hole 441B and drags the bearing 49 located in the discharge hole 441B to prevent it from falling out of the discharge hole 441B at will. Thus, only under the preset conditions, the limiting drag 462 retracts with the telescopic component 461, causing the bearing 49 to fall out of the discharge hole 441B.

[0064] Continue to refer to Figure 2 Please refer to them together. Figure 16 , Figure 16 This is a perspective view of the pressing device in a bearing pressing machine for motor housings, as described in this application. Figure 2 and Figure 16 As shown, the pressing device 50 includes a third support 51, a lifting pressing mechanism 52 fixed to the third support 51, and a double-bar lifting limit mechanism 33. The lifting pressing mechanism 52 is located between the double-bar lifting limit mechanisms 33, and the lifting pressing mechanism 52 can be freely raised and lowered. The center of the telescopic positioning device 60, the center of the pressing device 50, and the center of the limiting plate 21 are located on the same vertical line. The telescopic positioning device 60 positions the bearing 49 to be pressed from bottom to top. The telescopic positioning device 60 includes a telescopic cylinder 61 and a telescopic rod 62 connected to the telescopic cylinder 61. During operation, the telescopic rod passes through the turntable device 20, the limiting plate 21, and the motor housing 70 placed on the limiting plate 21 in sequence. The telescopic cylinder 61 drives the telescopic rod 62 to perform telescopic movement. It should be noted that after the motor housing 70 in the limiting plate 21 is limited by the double-rod lifting limiting mechanism 33, the telescopic positioning device 60 extends from bottom to top, thereby positioning the bearing 49. Then, the lifting pressing mechanism 52 presses the bearing 49 into the bearing mounting position after the hole is enlarged in the motor housing 70, which improves the accuracy of the bearing 49 pressing and avoids uneven pressing.

[0065] Here, the frame 10 is equipped with a turntable device 20, a shaping device 30, a bearing conveying device 40, a pressing device 50, and a telescopic positioning device 60. At least one set of limiting discs 21 are evenly distributed on the turntable device 20. The turntable device 20 is located between the telescopic positioning device 60 and the pressing device 50 along a preset direction. The shaping device 30, the bearing conveying device 40, and the pressing device 50 are all distributed circumferentially along the turntable device 20. Each of the shaping device 30, the bearing conveying device 40, and the pressing device 50 is directly opposite a limiting disc 21. The telescopic positioning device 60 passes through the turntable device 20 and the limiting plate 21 on the turntable device 20 along a preset direction and is directly opposite the pressing device 50. The center of the telescopic positioning device 60, the center of the pressing device 50 and the center of the limiting plate 21 are located on the same vertical line. This improves the concentricity of the bearing 49 and the reserved hole on the motor housing 70 during the pressing process of the bearing 49 in the bearing pressing machine for the motor housing. This makes the bearing 49 and the reserved hole on the motor housing 70 fit more closely, thereby effectively improving the product qualification rate.

[0066] To facilitate understanding, the working principle of this application is further described as follows: The bearing pressing machine for motor housings, through an external PLC controller, inputs a program into the PLC controller according to the sequence of first placing the motor housing 70 into the limiting plate 21, then expanding the hole, conveying the bearing, and pressing the bearing. This program, combined with the corresponding signal device, completes the pressing of the bearing 49 by the bearing pressing machine. This improves the concentricity of the bearing 49 and the reserved hole on the motor housing 70, making the bearing 49 fit the reserved hole on the motor housing 70 more closely, thereby effectively improving the product qualification rate.
