Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] like Figure 1 As shown, an automatic pressing equipment for automotive parts includes a frame 1;

[0046] A first feeding mechanism 2 for conveying the motor shaft to be processed is provided below the frame 1, and a lifting mechanism 4 for the motor shaft is arranged on the first feeding mechanism 2.

[0047] Positioning mechanism 5 is installed on frame 1, and lifting mechanism 4 extends upward from frame 1 to dock with positioning mechanism 5;

[0048] A second feeding mechanism 3 for conveying insulating sleeves is provided on the frame 1. A flipping mechanism 6 for the insulating sleeves is installed at the end of the second feeding mechanism 3. The flipping mechanism 6 is coaxial with the positioning mechanism 5.

[0049] The clamping and limiting mechanism 7 is arranged on the side of the positioning mechanism 5 away from the flipping mechanism 6, and is used to limit one end of the motor shaft to be processed;

[0050] The drive pressing mechanism 8 is arranged on the side of the flipping mechanism 6 away from the positioning mechanism 5, and is used to press the insulating sleeve onto the motor shaft to be processed;

[0051] The working principle and beneficial effects of the above embodiments are as follows:

[0052] The first feeding mechanism 2 of this utility model transports the motor shaft to be processed to the area below the processing position. The lifting mechanism 4 cooperates with the first feeding mechanism 2 to lift the motor shaft from the conveying position to the processing position. It extends upward out of the frame 1 and docks with the positioning mechanism 5, and accurately positions the motor shaft with the positioning mechanism 5 to ensure its stability and accuracy during the pressing process.

[0053] The second feeding mechanism 3 is responsible for conveying the insulating sleeve to be processed. The flipping mechanism 6 is installed at the end of the second feeding mechanism 3. It is used to adsorb the insulating sleeve and flip it 90 degrees to be coaxial with the motor shaft, so as to ensure that the insulating sleeve can be accurately fitted onto the motor shaft.

[0054] The clamping and limiting mechanism 7 is used to limit the position of one end of the motor shaft to be processed, ensuring that the motor shaft will not move during the pressing process; the driving clamping mechanism 8 is used to press the insulating sleeve onto the motor shaft to be processed, completing the assembly of the motor shaft and the insulating sleeve; then the lifting mechanism 4 transports the assembled motor shaft to the first feeding mechanism 2, which then transports it to the production line.

[0055] This utility model automates material feeding, positioning, and pressing, reducing manual operation and improving production line efficiency; at the same time, precise positioning ensures the assembly accuracy of the motor shaft and the insulating sleeve, improving the pressing quality.

[0056] In one embodiment,

[0057] like Figure 2-3As shown, the first feeding mechanism 2 includes a conveying guide rail 21 and a plurality of contour seats 22 mounted on the conveying guide rail 21. The motor shaft to be processed is placed on the contour seats 22. The lifting mechanism 4 is mounted on the conveying guide rail 21 and is located directly below the positioning mechanism 5.

[0058] The motor shaft to be processed is placed on the contour seat 22. As the conveying guide rail 21 moves, the motor shaft is conveyed to the position of the lifting mechanism 4. The conveying guide rail 21 is used to guide the movement of the contour seat 22, and the contour seat 22 is used to support the motor shaft to be processed. An arc-shaped groove matching the motor shaft is formed on the contour seat 22. The motor shaft is engaged in the arc-shaped groove to ensure the stability of the motor shaft during the conveying process. The combination of the conveying guide rail 21 and the contour seat 22 can effectively support and convey the motor shaft, improving the conveying efficiency.

[0059] In one embodiment,

[0060] The lifting mechanism 4 includes a lifting seat 41 mounted on the conveying guide rail 21, a first cylinder 42 mounted on the lifting seat 41, a guide seat 43 mounted on the telescopic end of the first cylinder 42, and a slot for placing the motor shaft on the guide seat 43. The guide seat 43 passes upward through the contour seat 22 along with the first cylinder 42 and lifts the motor shaft on the contour seat 22 upward to the positioning mechanism 5.

[0061] The lifting seat 41 is installed below the conveying guide rail 21 and does not interfere with the contour seat 22. The lifting seat 41 provides installation support for the first cylinder 42. A through slot for the guide seat 43 is provided on the contour seat 22. The guide seat 43 is installed on the telescopic end of the first cylinder 42. The guide seat 43 moves upward with the first cylinder 42, passes through the contour seat 22, and lifts the motor shaft on the contour seat 22 upward and raises it to the positioning mechanism 5. The precise control of the lifting mechanism 4 and the precise docking of the positioning mechanism 5 ensure the precise positioning of the motor shaft. A slot for placing the motor shaft is provided on the guide seat 43 to reduce the risk of the motor shaft sliding or shifting during the lifting process.

[0062] In one embodiment,

[0063] A vertical plate is provided on the frame 1, and a linear rail is installed on the vertical plate. The positioning mechanism 5 and the flipping mechanism 6 are slidably installed on the linear rail.

[0064] With precise guidance from the linear guide, the positioning mechanism 5 and the flipping mechanism 6 can be accurately moved to the predetermined position, ensuring the precise fit between the motor shaft and the insulating sleeve.

[0065] In one embodiment,

[0066] like Figure 4As shown, the positioning mechanism 5 includes a first sliding seat 51 that is slidably mounted on the rail, a positioning seat 52 that is mounted on the first sliding seat 51, and a guide groove for the motor shaft that is provided at the lower end of the positioning seat 52. The guide groove is connected to the placement groove for positioning the motor shaft. The positioning seat 52 is elastically connected to the upright plate.

[0067] The first sliding seat 51 is installed on the rail, enabling the positioning seat 52 to slide along the rail. The positioning seat 51 cooperates with the guide seat 43 for positioning the motor shaft. The positioning seat 52 is elastically connected to the vertical plate, providing a certain buffering and shock absorption capacity.

[0068] In one embodiment,

[0069] like Figure 5-6 As shown, the second feeding mechanism 3 includes a vibrating material plate 31 mounted on the frame 1, a feeding rod 32 communicating with the vibrating material plate 31, the feeding rod 32 being mounted obliquely on the frame 1, and a lifting component 33 being installed at the end of the feeding rod 32 away from the vibrating material plate 31.

[0070] The lifting assembly 33 includes a lifting seat 331 mounted on the frame 1. A second cylinder 332 is mounted on one side of the lifting seat 331. The feeding rod 32 is connected to the lifting seat 331. A contoured cavity for an insulating sleeve is opened on the lifting seat 331. The telescopic end of the second cylinder 332 passes through the lifting seat 331 and presses the insulating sleeve into the flipping mechanism 6.

[0071] The vibrating feeder 31 is used to store the insulating sleeves to be processed and feeds the insulating sleeves one by one into the feeding rod 32. The feeding rod 32 is installed at an angle to facilitate the flow of the insulating sleeves and to transport the insulating sleeves one by one into the contour cavity of the lifting seat 331. The telescopic end of the second cylinder 332 passes upward through the lifting seat 331 and presses the insulating sleeves in its contour cavity into the flipping mechanism 6. The second feeding mechanism 3 realizes the autonomous feeding of the insulating sleeves. The inclined design of the feeding rod 32 and the precise control of the lifting component 33 help to improve the feeding accuracy of the insulating sleeves.

[0072] In one embodiment,

[0073] The flipping mechanism 6 includes a flipping seat 61 slidably mounted on a linear rail, on which a gear shaft 62 is rotatably mounted. A sleeve 63 is engaged with the gear shaft 62, and the sleeve 63 rotates with the gear shaft 62. Figure 8 As shown, a conforming groove for engaging an insulating sleeve is provided at the end of the sleeve 63, and several vent holes are provided on the periphery of the conforming groove. These vent holes are connected to an air pipe and are used to adsorb the insulating sleeve inside the conforming groove.

[0074] A rack 64 that meshes with a gear shaft 62 is slidably mounted on a flip base 61. A sliding groove is provided on the flip base 61, and the rack 64 is installed in the sliding groove.

[0075] It also includes a third cylinder 65 mounted on the tilting base 61, the telescopic end of which is connected to a rack 64;

[0076] The flipping seat 61 is installed on the rail and can move laterally along the rail. The gear shaft 62 is rotatably installed on the flipping seat 61. When the gear shaft 62 rotates, it can drive the sleeve 63 to rotate. A contour groove is opened at the end of the sleeve 63. A vent hole is opened on the periphery of the contour groove and connected to an air pipe to adsorb the insulating sleeve in the contour groove, ensuring that the insulating sleeve will not fall off during the flipping process. The rack 64 meshes with the gear shaft 62. The third cylinder 65 drives the rack 64 to move and drives the gear shaft 62 to rotate, realizing the rotation of the sleeve 63. In order to further ensure the flipping angle of the sleeve 63 and make it accurately align with the lifting component 33 and the positioning mechanism 5, firstly, the extension and retraction of the third cylinder 65 is controlled, and secondly, limit posts 66 are installed on the flipping seat 61. The two limit posts 66 are installed vertically on the flipping seat 61 for the flipping positioning of the sleeve 63.

[0077] The insulating sleeve enters the contour groove of the sleeve 63 via the lifting assembly 33 and is attracted to the contour groove. The insulating sleeve is made coaxial with the motor shaft by rotating the gear shaft 62, and automatically flips over to improve the coaxial accuracy between the insulating sleeve and the motor shaft.

[0078] In one embodiment,

[0079] The clamping and limiting mechanism 7 includes a fixed base 71 mounted on the upright plate, a positioning guide post 72 slidably passing through the fixed base 71, an inclined groove at the end of the positioning guide post 72, an inclined slider 73 installed in the inclined groove, the inclined slider 73 being connected to the fifth cylinder 74, the moving direction of the inclined slider 73 being perpendicular to the moving direction of the positioning guide post 72, and a spring being sleeved on one end of the positioning guide post 72 near the inclined slider 73;

[0080] The positioning guide post 72 moves along the fixed base 71 to limit one end of the motor shaft. The fifth cylinder 74 drives the inclined slider 73 to move along the inclined groove. The moving direction of the inclined slider 73 is perpendicular to the moving direction of the positioning guide post 72.

[0081] When the fifth cylinder 74 drives the inclined slider 73 to approach the positioning guide post 72, the inclined slider 73 pushes the positioning guide post 72 to abut one end of the motor shaft. When the fifth cylinder 74 drives the inclined slider 73 to retract, the positioning guide post 72 is released by the spring force and returns to the initial position, which facilitates the loading and unloading of the motor shaft.

[0082] A mechanical structure is used to achieve precise positioning at one end of the motor shaft, which facilitates the control of the pressing force of the insulating sleeve by the driving clamping mechanism 8.

[0083] In one embodiment,

[0084] like Figure 7 As shown, the driving clamping mechanism 8 includes a fourth cylinder 81 mounted on the upright plate, the telescopic end of which is fixedly connected to the flipping seat 61.

[0085] It also includes a limiting member 82, which is mounted on the upright plate, and a limiting plate that mates with it is mounted on the flip base 61;

[0086] The fourth cylinder 81 provides power to drive the pressing action, and the limiting member 82 is used to limit the movement range of the flipping seat 61 to ensure the accuracy of the pressing action. When the extension end of the fourth cylinder 81 pushes the flipping seat 61 to move, the sleeve 63 rotates to the horizontal position and moves along the extension direction of the fourth cylinder 81 to realize the pressing action of the insulating sleeve against the motor shaft.

[0087] in,

[0088] When the sleeve 63 is displaced, one end of the motor shaft extends into the sleeve 63 and continues to displace along the inner cavity of the sleeve 63. At this time, the lifting mechanism 4 moves down and disengages from the motor shaft. When the flipping seat 61 is displaced to the limit position, the insulating sleeve and the motor shaft complete the pressing action. Because the positioning mechanism 5 has a certain buffering and shock absorption capacity, the insulating sleeve avoids damaging the positioning mechanism 5 at the moment of pressing.

[0089] Once the motor shaft is press-fitted, the lifting mechanism 4 moves upward to connect with the motor shaft and places it on the contour seat 22, and then moves it to the production line (discharge direction) via the conveying guide rail 21.
