Description

Technical Field

[0001] This invention relates to the field of mechanical assembly technology, and in particular to a step-by-step fast pressing system for vehicle frame rubber bushings. Background Technology

[0002] Frame bushing press-fitting refers to the initial press-fitting of rubber bushings on the frame swingarm or subframe according to standard specifications, pressing brand-new bushings into the swingarm or subframe. During the press-fitting process, it is important to ensure that the markings on the bushing are consistent with the indicated direction on the swingarm (or the vehicle's forward direction / locating pin). The front and back, and left and right, cannot be interchanged. During press-fitting, it is necessary to ensure that the axis of the press is aligned with the axis of the hole, applying pressure slowly and evenly. If any deviation is found, immediately retract and readjust the pressure until the end face of the bushing is flush with the plane of the swingarm and subframe, without any cut edges or skewing. Existing frame bushing press-fitting production lines often use a single press and a single robot arm working together. However, to accommodate bushings at multiple angles, the robot arm needs to change position or angle in multiple directions for multi-angle press-fitting. This single-press and single-robot press-fitting production line has low efficiency and yield, and the processing is difficult. One set of equipment can only adapt to the same type of frame, resulting in extremely poor versatility.

[0003] Therefore, there is an urgent need to develop a new facility or equipment that can adapt to various types of frames, solve the problem of single and non-universal production lines, and improve production efficiency and product qualification rate. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a step-by-step fast pressing system for vehicle frame bushings, which solves the problems of multi-angle adaptation, easy processing defects and low efficiency in existing single press and single robot pressing production lines, and improves the production efficiency and product qualification rate of vehicle frame bushing pressing.

[0005] This invention discloses a step-by-step rapid pressing system for vehicle frame rubber bushings. It includes: a feeding device for transporting the vehicle frame and rubber bushings into the pressing process;

[0006] The first pressing equipment is used to press the transported vehicle frame and rubber sleeves to form a semi-finished vehicle frame;

[0007] The second pressing equipment is used to press the unprocessed parts of the semi-finished vehicle frame;

[0008] The unloading device is used to deliver the pressed frame.

[0009] Furthermore, it also includes a detection device and a transfer platform. The detection device is set within the working range of the gripping device to detect the front and back of the rubber sleeve. The transfer platform is used to place some of the processed semi-finished vehicle frames. The gripping device includes a replaceable clamping mechanism, which enables the gripping device to grip rubber sleeves and vehicle frames of different models within the working range and transfer them to the pressing equipment.

[0010] Furthermore, the feeding device includes a rubber sleeve slide and a frame feeding platform. The rubber sleeve slide includes a first rubber sleeve slide and a second rubber sleeve slide. The first rubber sleeve slide and the second rubber sleeve slide are arranged opposite each other on both sides of the frame feeding platform. A conveyor frame is provided inside the frame feeding platform to transport the frame to the other end of the feeding platform.

[0011] Furthermore, the first pressing device and the second pressing device are two devices with the same structure but different placement positions; the first pressing device is for placing the rubber sleeve on the first rubber sleeve slide, and the second pressing device is for placing the rubber sleeve on the second rubber sleeve slide.

[0012] Furthermore, the gripping device includes two identical robotic arms, namely a first robotic arm and a second robotic arm. The first robotic arm clamps the frame on the frame loading platform and the rubber sleeve on the first rubber sleeve slide. The second robotic arm clamps the semi-finished frame clamped and pressed by the first robotic arm to the second pressing device, and clamps the processed frame to the unloading device.

[0013] Furthermore, the first pressing device includes a positioning detection mechanism, a C-shaped pressing mechanism, and a rotatable turntable. The C-shaped pressing mechanism forms an open C-shaped cavity, and the turntable is installed inside the C-shaped cavity. The turntable is provided with multiple floating pressing mechanisms along its circumference, so that the multiple floating pressing mechanisms can be used alternately in the C-shaped cavity as the turntable rotates. The positioning detection mechanism can accurately position the floating pressing mechanisms in the C-shaped cavity after they are rotated and replaced.

[0014] Furthermore, the clamping mechanism includes a driving component and a clamping component. The driving component can drive the clamping component to rotate and adjust the angle. The clamping component is provided with a frame claw and a rubber sleeve claw.

[0015] Furthermore, the floating pressing mechanism includes a lower pressing head, an upper pressing head, and a fixed base. The fixed base is provided with a slide rail, and the slide rail is provided with slider I and slider II. Slider I is provided with an upper pressing head, and slider II is provided with a lower pressing head.

[0016] This allows the upper and lower pressure heads to be constrained and slide freely along the slide rail direction;

[0017] A pneumatic spring is also provided between the lower pressure head and the fixed base, so that the lower pressure head can be driven to reset by the pneumatic spring.

[0018] A buffer spring is provided between the upper pressure head and the upper part of the fixed base, so that the buffer spring can be reset after the upper pressure head has worked.

[0019] Furthermore, the C-type pressing mechanism includes an upper pressing head adapter and a lower pressing head adapter; the lower pressing head adapter is provided with a drivable pressing rod, which can be driven to push the lower pressing head closer to the upper pressing head, and the upper pressing head adapter is provided between the upper pressing head and the C-type pressing mechanism to provide downward prestress.

[0020] Furthermore, the floating press mechanism also includes a thrust mechanism, which is located on the side near the upper press head and is used to insert the processed rubber sleeve.

[0021] The beneficial effects of this invention are as follows: This invention provides a step-by-step rapid pressing system for vehicle frame bushings. Through collaborative robotic arms (i.e., two robotic arms working simultaneously), each robotic arm is equipped with its own pressing device. Each robotic arm grips the frame and installs a portion of the bushing, while the other robotic arm grips and installs the remaining bushing before delivering it. This effectively breaks down the complex multi-angle pressing process that a single robotic arm would handle, with each arm responsible for pressing bushings at different angles. This improves efficiency and yield. The robotic arm's grippers are replaceable, allowing for quick adaptation to frame model changes, thus enhancing the system's versatility. The rapid-change grippers also adapt to various frame types, eliminating the need for specialized machines manufactured for specific frames that later become idle, thereby reducing equipment purchase and production costs.

[0030] like Figures 1 to 7 As shown: This embodiment illustrates a step-by-step fast-pressing system for a vehicle frame bushing. It includes:

[0031] A loading device is used to transport the chassis and rubber bushings into the pressing process. The step-by-step rapid pressing system for the chassis and rubber bushings is equipped with a partition 13, dividing the entire system into a processing area and a transfer area. The loading and unloading devices are located at two different positions within the system, not in the same location or integrated into a single device. The loading device passes through the partition 13 and transfers the chassis 11 and rubber bushings 12 to be processed into the processing area.

[0032] The first pressing equipment is used to press the transported vehicle frame and rubber sleeves to form a semi-finished vehicle frame. The first pressing equipment 6 is located on one side of the loading device and prioritizes pressing the unprocessed vehicle frames entering the processing area. During the pressing of the unprocessed vehicle frame, it is not completely pressed on the first pressing equipment 6; instead, only the parts of the frame that need pressing are pressed, forming a semi-finished vehicle frame. At this point, the pressing angle and equipment deflection angle are minimized, and the stroke is shortest, thereby improving the pressing accuracy and finished product efficiency. The equipment refers to the gripping device. The first pressing equipment 6 uses a floating-point pressing process to achieve automatic centering within a certain range of geometric errors, reducing the risk of off-center loading, protecting precision mating surfaces, and making the pressing force curve more realistic and stable; it also improves the finished product yield.

[0033] The second pressing device 10 is used to press the unprocessed parts of the semi-finished vehicle frame. The second pressing device 10 is located on the other side of the feeding device opposite to the first pressing device 6, and is used to press the remaining structure of the vehicle frame that the first pressing device 6 has not pressed. By decomposing the entire pressing process, compared to using a single machine to press the entire vehicle frame, it reduces pressing dead angles or situations where the rotation stroke is too long and the positioning accuracy is inaccurate. By using a half-stroke method to decompose the pressing dead angles, it is easier to press. The second pressing device 10 also adopts a floating-point pressing process, meaning that the first pressing device 6 and the second pressing device 10 use the same pressing process.

[0034] The unloading device is used to send out the pressed frame. The unloading device 4 is also installed through the partition so that the processed frame can be transported to the transfer area. The transfer area is equipped with a hoisting mechanism made of I-beams, which can hoist the frame.

[0035] In this embodiment, a gripping device, a detection device 5, and a transfer platform 8 are also included. The detection device 5 is positioned within the working range of the gripping device to detect the orientation of the rubber sleeve 12. The transfer platform 8 is used to place some of the processed semi-finished vehicle frames. The gripping device includes a replaceable clamping mechanism 702, enabling it to grip different models of rubber sleeves 12 and vehicle frames 11 within its working range and transfer them to the pressing device. During the pressing of the vehicle frame rubber sleeves, there is a strict orientation between the rubber sleeve 12 and the vehicle frame 11, so the gripping device must first check the orientation with the detection device 5 after gripping the rubber sleeve. Conversely, the detection device 5 can be an industrial camera or a dual-camera synchronous detection device, etc. The gripping device can clamp the identified rubber sleeve onto the pressing device in the correct forward and reverse order. The transfer table 8 can place the incomplete frame. By utilizing the gap of the transfer table 8, the processing angle and the part to be processed of the frame 11 are divided into two parts. By decomposing the angle that needs to be adjusted for processing a frame 11, the long rotation stroke of the gripping device and the accuracy problem in the adjustment process are reduced when processing a single deflection. The gripping device, acting as the central hub connecting the entire processing flow, adapts to variations in different vehicle frames 11 through a replaceable clamping mechanism 702. This ensures the processing flow is unaffected by the specific model of the vehicle frame 11 being processed, achieving universality in the processing of multiple vehicle frame models 11. The clamping mechanism 702 can grip the vehicle frame 11 and also utilizes a side gripper to hold the rubber sleeve 12, allowing both the rubber sleeve 12 and the vehicle frame 11 to be acquired on the same clamping mechanism 702 without the need for additional connecting or clamping mechanisms 702. This further simplifies the construction clamping environment, reduces environmental conflicts, and effectively utilizes construction space. After gripping the vehicle frame 11 and rubber sleeve 12 from the loading device, the gripping device places the rubber sleeve 12 on the pressing device, then places the clamped vehicle frame 11 on the pressing device for pressing. Finally, the gripping device places the pressed vehicle frame onto the unloading device 4 for transport, completing the entire flow processing process.

[0036] In this embodiment, the feeding device includes a rubber sleeve slide and a frame feeding platform 1. The rubber sleeve slide includes two identical slides, namely a first rubber sleeve slide 2 and a second rubber sleeve slide 3. The first rubber sleeve slide 2 and the second rubber sleeve slide 3 are arranged opposite each other on both sides of the frame feeding platform 1. A conveyor frame 102 is provided inside the frame feeding platform 1 to transport the frame 11 to the other end of the feeding platform. The conveyor frame 102 is provided on the frame feeding platform 1. The conveyor frame 102 has a plate-like structure and a number of forks 1021 and positioning posts 1022 are provided on its surface. The forks 1021 can effectively support and fix the unprocessed frame 11 to prevent sliding and displacement during transportation. The frame 11 has rubber sleeve mounting holes at its four corners. The positioning posts 1022 pass through the rubber sleeve mounting holes to position the frame 11 and prevent it from deflecting when it is gripped by the gripping equipment, thus avoiding subsequent rubber sleeve installation errors. A cylinder slide 101 is connected below the conveyor frame. The cylinder slide 101 can drive the conveyor frame 102 to slide back and forth along the length of the cylinder slide 101, thereby pushing the vehicle frame 11 into the processing area. The first rubber sleeve slide 2 adopts a double-layer feeding arrangement, that is, the first rubber sleeve slide 2 includes a conveyor frame body 205, an upper material rack 201, and a lower material rack 202. The conveyor frame body 205 is provided with a central pneumatic slide 204 and a side pneumatic slide 203. The upper material rack 201 is provided with support legs on both sides. The support legs are connected to the side pneumatic slides 203 on both sides of the conveyor frame 205. Specifically, the support legs are fixed to the sliders of the side pneumatic slides by bolts, so that the upper material rack 201 can be driven by the side pneumatic slides 203 to slide back and forth along the length of the conveyor frame. The lower material rack 202 is connected to the middle pneumatic slide 204, so that the lower material rack 202 can be driven by the middle pneumatic slide 204 to slide back and forth along the length of the conveyor frame 205.

[0037] In this embodiment, the first pressing device 6 and the second pressing device 10 are two devices with the same structure but different placement positions; they are the first pressing device 6 and the second pressing device 10, respectively, and the first pressing device 6 and the second pressing device 10 press the rubber sleeves 12 on different parts of the frame 11; the first pressing device 6 is correspondingly installed on the rubber sleeve 11 on the first rubber sleeve slide 2 held by the gripping device, and the first pressing device 6 can place multiple rubber sleeves 11 at one time, thereby improving work efficiency through the storage and use of multiple rubber sleeves 11; the second pressing device 10 is correspondingly installed on the rubber sleeve 11 on the second rubber sleeve slide 3 held by the gripping device.

[0038] In this embodiment, the gripping device includes two identical robotic arms, namely a first robotic arm 7 and a second robotic arm 9. The first robotic arm 7 clamps the frame 11 on the frame loading platform 1 and the rubber sleeve 12 on the first rubber sleeve slide 2. The second robotic arm 9 clamps the semi-finished frame clamped and pressed by the first robotic arm 7 to the second pressing device 10, and clamps the processed frame to the unloading device 4. The first robotic arm 7 and the second robotic arm 9 are two identical structures set in different positions. The first robotic arm 7 includes a robotic arm body 701 and a base 703. The base 703 is fixed to the ground by bolts. This ensures that the working range of the robotic arm body 701 is fixed and that it will not tip over due to changes in the center of gravity after the robotic arm grips an object. The robotic arm body 701 adopts a two-link robotic arm, which is existing technology and will not be described in detail here. When the first robotic arm 7 grips the rubber sleeve to the pressing equipment for installation, it should first be tested by the testing device 5. After the test is completed, it is installed on the first pressing equipment 6 in sequence. Then, the first robotic arm 7 grips the frame 11 on the frame loading platform 1 and presses it onto the first pressing equipment 6. The semi-finished frame after pressing is held by the first robotic arm 7 and placed on the transfer platform 8. Finally, the second robotic arm 9 grips it to complete the subsequent processing operations.

[0039] In this embodiment, the first pressing device includes a positioning detection mechanism 602, a C-shaped pressing mechanism 601, and a rotatable turntable 605. The C-shaped pressing mechanism 601 forms an open C-shaped cavity, and the turntable 605 is installed inside the C-shaped cavity. The turntable has multiple floating pressing mechanisms 603 arranged circumferentially, allowing the floating pressing mechanisms 603 to rotate and be used interchangeably within the C-shaped cavity as the turntable 605 rotates. The positioning detection mechanism 602 can accurately position the floating pressing mechanisms 603 within the C-shaped cavity after rotation. The turntable 605 has a ring structure, with a gear ring below it. The gear ring is bolted to the turntable 605, allowing it to engage with a motor built into the first pressing device, enabling the turntable to rotate. A mounting ring is provided at the lower part of the gear ring, and the gear ring is bolted to the mounting ring. The mounting ring can be a plane bearing, allowing the gear ring to be rotated by the motor without jamming. The C-type pressing mechanism 601 is fixedly mounted on the top of one side of the turntable and has a lifting ring 6013. The lifting ring 6013 can facilitate the lifting of the entire first pressing device. Multiple floating pressing mechanisms 603 are provided along the turntable 605. In this scheme, there are two sets of floating pressing mechanisms 603 relative to the center, that is, four floating pressing mechanisms 605. The floating pressing mechanisms 603 can rotate with the turntable 605, so that the floating pressing mechanisms can be replaced sequentially in the C-shaped cavity of the C-type pressing mechanism. The positioning detection mechanism is equipped with a return sensor, and the return sensor is equipped with an upper pressure head return sensing plate 6021. When the floating pressing mechanism 603 completes the pressing and rotates with the turntable 605, the upper pressure head return sensing plate 6021 will control the motor to stop rotating after sensing the floating pressing mechanism 603.

[0040] In this embodiment, the clamping mechanism 702 includes a drive component 7021 and a clamping component 7022. The drive component 7021 can drive the clamping component to rotate and adjust the angle. The clamping component 7022 is provided with a frame gripper 7022b and a rubber sleeve gripper 7022c. The ends of the two identical first robotic arms 7 and second robotic arms 9 are connected by bolts to replaceable clamping mechanisms 702. The frame gripper 7022b can grasp the frame and move it to the pressing equipment for pressing. The rubber sleeve gripper 7022c can grasp the rubber sleeve and place it on the pressing equipment. The integrated clamping component eliminates the need for frequent clamp replacement, saving repeated work and improving work efficiency. The clamping component is provided with a drive source 7022a. The drive source 7022a can be a device for linear motion drive, such as a hydraulic cylinder, a lead screw, or a pneumatic cylinder. Here, a pneumatic cylinder is preferably used as the drive source to drive the frame gripper 7022b to clamp or release the waiting frame.

[0041] In this embodiment, the floating pressing mechanism 603 includes a lower pressing head 6032, an upper pressing head 6031, and a fixed base 604. The fixed base 604 is provided with a slide rail 6036, on which slide rail 6036 are provided slider I 6034 and slider II 6033. Slider I 6034 is provided with the upper pressing head 6031, and slider II 6033 is provided with the lower pressing head 6031, so that the upper and lower pressing heads can be constrained to slide freely along the slide rail 6036; the fixed base 604 is... The upper pressure head 6031 is fixedly connected to the turntable 605 by bolts. The slide rail 6036 is also fixed to the fixed base 604 by bolts. The slide rail 6036 is set perpendicular to the turntable 605. The upper pressure head 6031 is fixed to the slider I 6034 and the lower pressure head 6032 is fixed to the slider II 6033. When the upper pressure head 6031 and the lower pressure head 6032 can be driven close together, the pressing force is ensured to be transmitted in a vertical straight line without deviation, thus improving the installation accuracy of the rubber sleeve.

[0042] A pneumatic spring 6037 is also provided between the lower pressure head 6031 and the fixed base 604, so that the lower pressure head 60321 can be driven to reset by the pneumatic spring 6037. The pneumatic spring 6037 is provided between the lower pressure head 6032 and the fixed base 604. The pneumatic spring 6037 is arranged parallel to one side of the slide rail 6036, and its two ends are respectively fixed to the fixed base 604 and the slider II 6033. This allows the lower pressure head 6032 to automatically reset after being driven close to the upper pressure head 6032. Compared with conventional springs, the pneumatic spring can be customized in terms of force, stroke and direction, realizing buffer damping and protecting the floating pressing mechanism.

[0043] A buffer spring 6035 is provided between the upper pressure head 6031 and the upper part of the fixed base 604, so that the upper pressure head 6031 can be reset by the buffer spring 6035 after working. The upper pressure head 6031 is provided with a buffer spring 6035, which is arranged parallel to the slide rail 6036. When pressing, the upper pressure head 6031 is subjected to upward force, and the buffer spring 6035 provides part of the support force to prevent stress change caused by sudden application of lower torque during pressing. This makes the force distribution more uniform and linear throughout the pressing process, further improving the installation quality and protecting the installed product. After the upper pressure head 6031 has finished pressing, the buffer spring 6035 applies a downward force to make the upper pressure head return to its original position, waiting for the next processing.

[0044] In this embodiment, the C-type pressing mechanism 601 includes an upper pressing head adapter 6011 and a lower pressing head adapter 6012; the lower pressing head adapter 6012 is provided with a drivable pressing rod 6013, which can be driven to push the lower pressing head 6032 closer to the upper pressing head 6031; the upper pressing head adapter 6011 is disposed between the upper pressing head 6031 and the C-type pressing mechanism 601 to provide downward prestress. The lower pressure head adapter 6012 is a hollow cylindrical structure. The pressing rod 6013 passes through the lower pressure head adapter 6012 and contacts the lower pressure head 6032. The pressing rod 6012 is the output end of the worm gear. The driving component 6014 of the worm gear is vertically installed below the C-type pressing mechanism 601 to push the lower pressure head 6032 closer to the upper pressure head 6031 to complete the installation. The upper pressure head adapter 6011 is a cylindrical structure and is fixedly installed above the C-type pressing mechanism by bolts. The upper pressure head adapter 6011 is set as a support between the upper pressure head 6031 and the C-type pressing mechanism 601. The setting of the upper pressure head adapter 6011 prevents the upper pressure head 6031 from moving backward due to the upward force of the lower pressure head 6032 during the pressing of the rubber sleeve 12, thus preventing the rubber sleeve pressing from failing due to the lack of support force. This further improves the limiting and supporting functions.

[0045] In this embodiment, the floating pressing mechanism 603 further includes a thrust mechanism, which is located on the side near the upper pressing head 6031 and is used for inserting the rubber sleeve 12. The thrust mechanism is located below the upper pressing head and includes a thrust cylinder 6039 and a rubber sleeve clamp 6038. The rubber sleeve fork 6038 can be pushed by the thrust cylinder 6039 through the floating pressing mechanism 603 to insert the rubber sleeve 11 on the gripping device. The rubber sleeve fork 6038 is provided with a support leg 6038a that passes through the slider I 6034. Located on both sides of the fixed base 604, the support leg 6038a is provided with a reset component 6038b. The reset component 6038b can be a device such as a spring or a cylinder that can push the rubber sleeve fork 6038 to reset. Here, a spring is preferred as the reset component. The thrust cylinder 6039 and the rubber sleeve fork 6038 are driven by an intermittent drive. After the fork is lifted, the reset component 6038b drives the rubber sleeve fork 6038 to reset. The thrust cylinder 6039 does not participate in the drive. The reset accuracy is ensured only by the reset spring.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
