Description

Technical Field

[0001] This invention relates to the field of intelligent manufacturing technology, specifically to a multi-station flexible automatic pressing device for electric drive housing components. Background Technology

[0002] Currently, components such as conductive rings, oil distribution plates, bearing outer rings, and locating pins of electric drive system housings are typically press-fitted one by one manually or using semi-automatic equipment at independent workstations. Existing equipment is mostly machine-specific or part-specific, lacking universal fixtures and quick-change mechanisms. Changeovers require manual replacement of the entire tooling set, resulting in low switching efficiency and insufficient flexibility. Conductive rings, oil distribution plates, and bearing outer rings require multiple clamping and handling operations between multiple machines, leading to lengthy processes, accumulated errors, and significant cycle time losses. Summary of the Invention

[0014] Furthermore, the component feeding slide mechanism includes a mounting side plate, horizontal guide rails, a feeding translation plate, a horizontal lead screw, a feeding servo motor, and a component tray. The mounting side plate is vertically fixed to the inner side of the column of the rigid structural frame located below the middle platform.

Detailed Implementation

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] like Figure 1 The diagram shows a type of electric drive housing 10 placed horizontally on a tray with one end facing upwards. When the robot uses a gripper to grasp the electric drive housing, the gripper is positioned and clamped against the outer peripheral sidewall structure of the electric drive housing.

[0043] like Figures 2-15 As shown, one embodiment of the present invention is: a multi-station flexible automatic pressing device for electric drive housing components, comprising: The line conveying unit 20 is used to convey the electric drive housing 10 to the pressing waiting area, and to continue to convey the qualified electric drive housing after pressing to the next process position. The robot gripper unit includes a robot 30 and a gripper library 40. The gripper library 40 is equipped with multiple grippers 41 for gripping different models of electric drive housings. Each gripper 41 has a flange interface 411 at its end. The end of the robot arm is equipped with a quick-change plate mechanism 31 that matches the flange interface 411. After the robot's quick-change plate mechanism 31 is docked and locked with the flange interface 411 of the gripper, the robot 30 can automatically pick up the corresponding model of electric drive housing 10 through the gripper 41 and transport it between workstations. The automatic pressing unit 50 includes a rigid structural frame 51, an electric cylinder servo pressing mechanism 52, an electric cylinder positioning mechanism 53, a multi-station pressing head mechanism 54, a pressing head positioning mechanism 55, a housing positioning reaction force support mechanism 56, a clamping mechanism 57, and a component feeding slide mechanism 58. The electric cylinder servo pressing mechanism 52 is located on the upper layer of the rigid structural frame 51 and outputs vertically downward pressing power. The electric cylinder positioning mechanism 53 drives the electric cylinder servo pressing mechanism 52 to translate horizontally along the X and Y directions. The multi-station pressing head mechanism 54 is located in the middle layer of the rigid structural frame 51 and includes a pressing head mounting base 541 and multiple pressing head modules 542. The pressure head module 542 is mounted on the pressure head mounting base 541. Each pressure head module 542 can be individually driven to move its own pressure head 5424 relative to the pressure head mounting base 541. The pressure head displacement mechanism 55 is used to drive the pressure head mounting base 541 and multiple pressure head modules 542 to move synchronously in the horizontal direction along the X and Y directions. The housing positioning reaction force support mechanism 56 is located at the bottom of the rigid structure frame 51. The housing positioning reaction force support mechanism 56 is used to position and support the electric drive housing 10 and to provide rigid reaction force support directly below the pressing position of the electric drive housing component. The pressing mechanism 57 is used to press the electric drive housing 10 from above. The component feeding slide mechanism 58 is used to transport the component to be pressed from the rigid structure frame to the bottom of the multi-station pressure head mechanism. The slide sorting unit 80 is used to transport the press-fitted defective electric drive housings to the rework station.

[0044] The robot selects a fixture compatible with the electric drive housing from the fixture library, moves the electric drive housing from the production line conveyor unit to the housing positioning reaction support mechanism of the automatic pressing unit, and the pressing mechanism clamps the electric drive housing. The component feeding slide mechanism feeds the component in. During pressing, the corresponding pressing head module grips the corresponding component from the component feeding slide mechanism, and the pressing head displacement mechanism moves the corresponding pressing head to the corresponding position above the electric drive housing. The electric cylinder displacement mechanism also moves the electric cylinder servo pressing mechanism to the corresponding pressing head. The corresponding reaction support mechanism is positioned to provide rigid reaction support for the pressing position of the electric drive housing. The electric cylinder servo pressing mechanism then applies vertically downward pressing force to the corresponding pressing head module, completing the pressing of the component. The automatic pressing unit then sequentially presses the components at designated positions on the electric drive housing. Finally, the robot automatically sorts the qualified and unqualified electric drive housing parts.

[0045] The beneficial effects of adopting the above technical solution are: each unit operates in coordination through a unified control system, constructing a fully automated process from conveying, gripping, pressing to sorting, reducing manual intervention, reducing labor intensity, avoiding errors caused by manual operation, improving production consistency, forming an integrated and closed-loop pressing execution structure, supporting flexible assembly of electric drive housings of multiple models and controllable operation throughout the process.

[0046] like Figure 3 , Figure 4 As shown, in some other embodiments of the present invention, the fixture library 40 includes a support frame 43, on which a plurality of fixture placement positions are arranged in parallel. Each fixture placement position is provided with a fixture positioning pin 431 at its front end and rear end. The fixture 41 includes a fixture main structure frame 412, a flange interface 411, a fixed end lateral positioning frame 413, a movable end lateral positioning frame 414, and a movable end opening and closing drive mechanism 415. The bottom surface of the fixture main structure frame 412 is provided with a fixture positioning pin 431. The positioning pin 431 matches the fixture positioning hole, and the flange interface 411 is fixedly installed at one end of the main fixture frame 412. The fixed end lateral positioning frame 413 is fixedly installed at the other end of the main fixture frame 412. The movable end lateral positioning frame 414 is slidably installed on the double-sided slide rail assembly of the main fixture frame. The movable end opening and closing drive mechanism 415 is used to drive the movable end lateral positioning frame 414 to translate along the main fixture frame 412 to achieve clamping and releasing of the electric drive housing 10. The beneficial effects of adopting the above technical solution are: the multi-position design of the fixture library can realize the centralized storage and precise positioning of multiple types of fixtures; the fixtures cooperate with the positioning pins and positioning holes to ensure the positioning accuracy when the robot grasps the fixtures; the movable end lateral positioning frame translates through the double-sided slide rail assembly, and cooperates with the linear drive mechanism to achieve stable clamping and releasing, adapting to the outer peripheral structure of the corresponding electric drive housing, improving clamping reliability and versatility.

[0047] like Figure 3 , Figure 4 As shown, in some other embodiments of the present invention, each clamp has two positioning elements and one support element on its fixed end lateral positioning frame 413 and movable end lateral positioning frame 414, which cooperate with the outer peripheral structure of the electric drive housing of the corresponding clamping model. The beneficial effect of adopting the above technical solution is that the combined design of two positioning elements and one support element can form a three-point positioning support for the electric drive housing from the side and bottom, fit the outer peripheral structure of the housing, ensure the stability and positioning accuracy during clamping, avoid the housing from shifting or falling off during transportation, and ensure the accuracy of subsequent pressing processes.

[0048] like Figure 3 , Figure 4 As shown, in some other embodiments of the present invention, the movable end opening and closing drive mechanism 415 is a linear cylinder. The beneficial effects of adopting the above technical solution are: the linear cylinder drive has a rapid response and stable power output, which can realize the rapid opening and closing of the movable end lateral positioning frame, and improve the efficiency of clamping and releasing.

[0049] like Figure 4As shown, in some other embodiments of the present invention, the main structure frame 412 of the clamp is provided with a first limiting mechanism 416 and a second limiting mechanism 417 for limiting the movement position of the movable end lateral positioning frame; when the movable end lateral positioning frame 414 abuts against the first limiting mechanism 416, the electric drive housing is clamped; when the movable end lateral positioning frame 414 abuts against the second limiting mechanism 417, the electric drive housing is released. The beneficial effects of adopting the above technical solution are: the first limiting mechanism and the second limiting mechanism clearly define the end point of the travel of the movable end lateral positioning frame, ensuring that the clamping force is stable and consistent during clamping, and that the opening size during release meets the housing loading and unloading requirements, avoiding problems such as insecure clamping or housing collisions caused by travel deviation, and improving the stability and safety of the clamp operation.

[0050] like Figure 3 As shown, in some other embodiments of the present invention, a baffle plate 418 and a swing cylinder 419 for controlling the opening and closing of the baffle plate 418 are provided at the end of the main fixture frame 412 corresponding to each fixture placement position. When the baffle plate 418 is in the closed state, the baffle plate 418 covers the end face of the flange interface 411. When the baffle plate 418 is in the open state, the baffle plate 418 is located below the flange interface 411. The beneficial effects of adopting the above technical solution are: the baffle plate is closed when the fixture is not in use, which can effectively prevent dust, debris and other contaminants from contaminating the end face of the flange interface and ensure the docking accuracy of the flange interface and the robot quick-change plate mechanism; when in use, it is automatically opened by the swing cylinder, which does not affect the docking operation and improves the protection and docking reliability of the equipment.

[0051] In other embodiments of the present invention, the electric cylinder servo pressing mechanism 52 includes a servo motor, a ball screw, a piston rod, a force sensor, and a displacement encoder. The servo motor drives the ball screw and piston rod to generate linear thrust. The force sensor is used to detect the real-time load during the pressing process, and the displacement encoder is used to provide feedback on the real-time stroke data during the pressing process. The beneficial effects of adopting the above technical solution are: the servo motor and ball screw work together to achieve precise control of the linear thrust, meeting the pressing force requirements of different components; the real-time detection and feedback of the force sensor and displacement encoder realize force-displacement dual closed-loop control of the pressing process, facilitating the control system to monitor the pressing process, promptly identify abnormalities and stop the machine, and prevent unqualified products from being shipped out. The control system can call the corresponding pressing curve according to the process requirements of different parts and automatically record the data of the entire pressing process, ensuring the stability and consistency of pressing depth, pressing force, and assembly posture.

[0052] like Figure 6As shown, in some embodiments of the present invention, the rigid structural frame 51 of the automatic pressing unit includes an upper platform 511, a middle platform 512, and a bottom platform 513 distributed vertically at intervals. The middle of the upper platform 511 and the middle of the middle platform 512 are vertically connected. The beneficial effects of adopting the above technical solution are: the three-layer platform structure realizes the layered layout of the electric cylinder servo pressing mechanism, the multi-station pressing head mechanism, and the housing positioning reaction force support mechanism, resulting in high space utilization; the vertically connected middle structure ensures the vertical transmission of pressing force, avoids force offset loss, and improves pressing accuracy; the rigid structural frame has high overall strength, can resist the reaction force during the pressing process, and ensures the long-term stability of the equipment.

[0053] like Figure 6 , Figure 7 As shown, in some other embodiments of the present invention, the electric cylinder positioning mechanism 53 includes a first base plate 531, a first X-axis guide rail assembly 532, a first X-axis servo drive mechanism 533, a first X-axis translation plate 534, a first Y-axis guide rail assembly 535, a first Y-axis servo drive mechanism 536, and a first Y-axis translation plate 537. The first base plate 531 is fixedly mounted on the upper platform 511. The guide rail of the first X-axis guide rail assembly 532 is fixed to the upper surface of the first base plate 531 along the X-axis direction. The first X-axis translation plate 534 is mounted on the first... On the slider of the X-axis guide rail assembly 532, a first X-axis servo drive mechanism 533 drives a first X-axis translation plate 534 to translate along the X-axis. The guide rail of the first Y-axis guide rail assembly 535 is fixedly mounted on the first X-axis translation plate 534 along the Y-axis.

[0055] In other embodiments of the present invention, the pressure head mounting base 541 has a vertically upward extending annular wall 5411 in the middle, and each pressure head module 542 is arranged in a ring along the annular wall.

Each pressure head 5424 is detachably connected to the bottom end of the pressure rod 5421 through a quick-locking structure, and each pressure head 5424 has a guide structure that matches the corresponding part to be pressed.

The beveled fork tooth 5646 pushes the reaction column 5642 upward through its upper beveled surface. The root of the beveled surface of the beveled fork tooth 5646 also has a horizontal surface. The beneficial effects of adopting the above technical solution are: the inclined fork tooth realizes the vertical lifting of the reaction column through horizontal translation, which has high transmission efficiency and accurate positioning; the horizontal plane at the root of the inclined plane can form a stable support for the reaction column after lifting, ensuring that the reaction column does not sink during the pressing process and ensuring the stability of the reaction support; the through hole design of the guide seat plays a guiding role for the reaction column, avoiding deviation during the lifting process and improving the accuracy of the reaction support.

Different models of components are equipped with component specification plates 588 that match their structure. The component tray 586 is also equipped with a sensor for detecting whether the component is in place.
