Description

Technical Field

[0001] This invention belongs to the field of aluminum alloy parts assembly, and specifically relates to a plastic plug pressing device. Background Technology

[0002] Aluminum alloy steering knuckles are core components of automotive steering systems. Many important parts related to safety, such as brake calipers and steering control arms, are connected to the wheel hub through steering knuckles. Currently, in most two-wheel-drive vehicles, after the steering knuckle is machined, a plastic cap is pressed into the pre-drilled center hole to achieve a dustproof, waterproof, and dirt-proof sealing effect, ensuring the performance and service life of the steering knuckle.

[0003] Plastic plugs are relatively lightweight, requiring a maximum force of 1500-2500N for press-fitting. Assembly relies on four clamps to engage with the steering knuckle, and angle requirements exist. Current methods for press-fitting steering knuckle plastic plugs are mainly divided into manual and pneumatic types. Manual methods rely entirely on manual operation; the pressing force, angle, and alignment depend entirely on experience and visual control, demanding high operator skill and precision. Alignment is difficult to guarantee, easily causing clamp damage or breakage, resulting in extremely low efficiency. This method is only suitable for small-batch installations and repairs. Pneumatic methods use small pneumatic devices with cylinder-driven pressing. However, the pressing pressure and cylinder speed cannot be controlled, easily leading to excessive force causing deformation, over-pressing, or insufficient force resulting in incomplete pressing. Furthermore, the cylinder-driven device lacks effective personnel protection measures, posing a significant risk of injury and safety hazards. Additionally, the positioning fixtures are often simple devices, unable to precisely position the steering knuckle and ensure proper alignment during press-fitting. Furthermore, both of the above methods lack effective monitoring of the cap pressing quality after pressing, making it impossible to identify defective products such as improper pressing, cap misalignment, damaged cap claws, and incorrect cap installation angle in a timely manner. A large amount of manpower is required for re-inspection, which not only poses a great risk of defective products being released but also increases production costs.

[0004] Therefore, designing a plug pressing machine that is highly adaptable, has high pressing accuracy, is safe for operators, has high pressing efficiency, can monitor pressing quality in real time, and can detect the angle and claw status of the plug after assembly has become an urgent technical problem to be solved in the automotive steering knuckle manufacturing industry. Summary of the Invention

[0005] This invention proposes a plastic plug pressing device to solve the problems of poor adaptability, low pressing accuracy and efficiency in the prior art.

[0006] To achieve the above objectives, the present invention proposes the following technical solution: A plastic plug pressing device includes a workbench frame, a worktable, a C-shaped base, a press head mounting base, a camera, a vision system bracket, a motor, a servo motor, a press head, and a steering knuckle positioning base; The workbench includes a cabinet and a frame, with the frame positioned on top of the cabinet and the workbench located inside the frame.

[0009] Preferably, it also includes an L-shaped connecting block, which is disposed below the servo electric cylinder, and the slider on the linear guide is connected to the pressure head mounting seat through the L-shaped connecting block.

[0010] Preferably, it also includes a limiting block, which is installed at the lower limit of the downward movement of the pressure head mounting seat and is located in the middle of the C-shaped base.

[0011] Preferably, a sensor bracket is arranged above the workbench, and a through-beam sensor or a vision sensor is installed on the sensor bracket.

[0018] The advantages of this invention are: This invention proposes a plastic plug pressing device. It achieves precise positioning of the steering knuckle through a steering knuckle positioning seat, and ensures the plug is placed correctly via a press head air detection pipeline, thus guaranteeing good alignment during pressing. The pressing control method using a servo electric cylinder allows for setting the force and speed at different stages of the pressing process, preventing damage to the clamps due to excessive pressing force or incomplete pressing due to insufficient force. A camera enables post-pressing inspection of the plastic plug, preventing defective products from being shipped out. This reduces manual inspection time and the difficulty of manual installation, making it suitable for continuous automated pressing of large-volume products, greatly improving batch production efficiency and pressing quality.

Steering Knuckle Positioning Pin 38. Notch 39. Claw 40. Cabinet 111 and L-shaped Connecting Block 112.

[0023] This invention is used to press a part into a workpiece to be processed. In this embodiment, the part is a plastic plug 34 and the workpiece to be processed is a steering knuckle 35. This invention is used to press the plastic plug 34 into the center hole of the steering knuckle 35.

[0024] The present invention includes a main body of equipment, a pressure electric cylinder control system, a camera vision recognition system, and a steering knuckle positioning fixture.

[0025] The main body of the equipment includes a workbench frame 1, a workbench 2, a C-shaped base 3, a pressure head mounting base 5, a barcode scanner 7, a safety light curtain 9, a two-hand start device 10, a sensor bracket 12, a three-color warning light 14, an equipment support beam 28, and an aviation plug interface 29.

[0026] The workbench 1 is the supporting part of the main body of the equipment, forming the main frame of the equipment. The workbench 1 includes a cabinet 111 and a platform. The platform is a square frame and is set on top of the cabinet 111. The camera vision recognition system is placed in the cabinet 111, and other parts are arranged on the platform.

[0027] The top of the cabinet 111 is equipped with a workbench 2, which is located inside the frame and includes a transition plate 4, a tooling positioning pin 6, and a transition plate positioning block 11. The transition plate 4 is positioned above the base plate of the workbench 2 and connected via bolt positioning holes. The transition plate positioning block 11 is mounted on the transition plate 4 to limit its movement. During tooling installation, the bolt holes of the transition plate 4 can be quickly aligned with the bolt holes on the upper surface of the workbench 2, improving the efficiency of tooling changeover. The tooling positioning pin 6 is located in the middle of the transition plate 4, and the pressure head mounting seat 5 is located on the top inner side of the workbench frame 1. The center of the tooling positioning pin 6 is aligned with the center of the pressure head mounting seat 5 directly above the transition plate 4 to ensure good alignment between the positioning tooling and the pressure head of the equipment after installation on the workbench.

[0028] The C-shaped base 3 is installed on the upper surface of the workbench 2 and is connected to the workbench 2 through the bolt holes in the base of the C-shaped base 3. The linear guide rail 24 is installed on the C-shaped base 3, and the slider on the linear guide rail 24 is connected to the pressure head mounting seat 5 through the L-shaped connecting block 112. The pressure head 30 is installed on the pressure head mounting seat 5. The pressure head mounting seat 5 has an opening, and the pressure head 30 has a slot. When installing the pressure head 30, the bolts are used to lock the pressure head 30 to the opening on the pressure head mounting seat 5 and the slot on the pressure head 30, thereby realizing the connection between the pressure head 30 and the pressure head mounting seat 5.

[0029] The pressure electric cylinder control system comprises a motor 21, a servo electric cylinder 22, a pressure sensor 23, a linear guide rail 24, a cable chain 25, a display touch screen 13, and a limit stop 8.

[0030] A replaceable pressure head 27 can be provided between the pressure head 30 and the pressure head mounting base 5, the replaceable pressure head 27 being used to extend the pressure head 30.

[0031] The servo cylinder 22 is installed above the C-shaped base 3 and is connected to the motor 21. The motor 21 drives the servo cylinder 22 to move vertically downward. When the pressure head 30 is installed on the pressure head mounting seat 5, after the equipment starts the pressing command, the motor 21 drives the servo cylinder 22 to move downward. An L-shaped connecting block 112 is provided below the servo cylinder 22, which also moves downward, thereby driving the pressure head mounting seat 5 to move downward as well. The replaceable pressure head 27 also moves downward, pressing the plastic plug 34 into the steering knuckle 35. When the plastic plug is pressed into place, the pressure of the pressure sensor 23 rises sharply. After reaching the set pressure threshold (equipment protection force), a command is issued for the servo cylinder 22 to return. At this time, the pressure head mounting seat 5 rises, driving the replaceable pressure head 27 to rise, and the servo cylinder 22 returns to the equipment origin.

[0032] The limiting block 8 is installed at the lower limit of the downward movement of the pressure head mounting base 5 and is located in the middle of the C-shaped base 3, which limits the movement of the pressure head mounting base 5.

[0033] A sensor bracket 12 is also arranged above the workbench 2 near the frame for mounting a through-beam sensor to detect whether the steering knuckle or the plug is placed during press-fitting. The sensor bracket is made of a slider and a support rod, with most of the support rods set on the workbench 2. The slider slides up and down along the support rods to adjust its position and achieve detection at different positions.

[0034] The barcode scanner 7 is located on the upper surface of the workbench 2. The fixed position of the steering knuckle 35 has a pre-engraved QR code. The operator manually holds the barcode scanner 7 to scan the QR code on the press-fitted steering knuckle 35. After scanning, the information is entered into the equipment, realizing the association and traceability of each QR code with each product. The product traceability function cannot be realized when manually installing or using a pneumatic hydraulic cylinder for press-fitting.

[0035] Further reference Figure 1 The safety light curtain 9 is installed on both sides at the front of the platform. Through-beam sensors are arranged in the safety light curtain 9. When the operator places the steering knuckle and the plug, or when personnel are detected working inside the equipment, the through-beam sensors on both sides of the safety light curtain are blocked from detection. At this time, the equipment cannot move and the motor 21 cannot start working.

[0036] The two-hand start device 10 is located at the frontmost part of the bottom of the platform and the outermost part of the equipment, with a button on each of the left and right sides. When the pneumatic equipment is being pressed, the worker needs to place both hands on one side and press both buttons simultaneously to start the equipment, thus preventing worker injury. Compared with manual installation and pneumatic installation, this design structure can ensure the safety of workers and prevent safety accidents caused by worker misoperation.

[0037] The touch screen 13 is suspended on the right side of the workbench 1. The touch screen 13 is integrated into a small computer. The force-displacement curve during cap pressing, equipment sensor signals, tooling sensor models, product QR code input information, cap QR code input information, and cap pressing program are all displayed on this touch screen. Different pressing displacement parameters, speed parameters, and force parameters can be set according to different products and different tooling to achieve pressing of different products.

[0038] like Figure 3 As shown, the camera vision recognition system includes a camera 15, a camera bracket 16, a camera guard plate 17, a camera guard plate cylinder 18, a camera light source 19, and a vision system bracket 20. The camera light source 19 is arranged around the camera 15, encircling it. A circular slot is located in the center of the camera light source 19 through which the camera 15 passes. The camera 15 is mounted on the camera bracket 16. The camera guard plate cylinder 18 is located on the left side of the camera guard plate 17 and connected to it by bolts. The camera guard plate 17 is positioned directly above the camera 15. Both the camera guard plate cylinder 18 and the camera bracket 16 are mounted on the vision system bracket 20, which is located inside a cabinet 111. The camera guard plate cylinder 18 is connected to the camera guard plate 17 to achieve movement control of the camera guard plate.

[0039] In the implementation case of using a camera vision recognition system, the tooling positioning pin 6 is replaced with a cylindrical positioning pin with a central through hole, which is used to enable the camera's photo-taking function. The positioning fixture is installed on the tooling positioning pin 6 to ensure alignment with the equipment. After the plastic plug 34 is pressed in, the camera guard cylinder 18 receives a command from the equipment and retracts to the left, causing the camera guard 17 to move to the left. At this time, the camera light source 19 emits light, illuminating the clamping claw 40 after the plug is pressed in, and the camera 15 takes a picture. After the picture is taken, the camera guard cylinder 18 extends, causing the camera guard 17 to extend and return to above the camera 15 to continue protecting the lens of the camera 15. It will move again after the next pressing is completed. The captured picture is transmitted to the equipment, and the set image grayscale algorithm is used to determine whether the clamping claw 40 is damaged and whether the plug installation angle is correct. If the pressing is deemed qualified, the green light of the three-color warning light 14 located on the top outer side of the platform lights up. If the pressing is deemed unqualified, the red light of the three-color warning light 14 lights up. During the assembly of plastic plugs, the clamps 40 are prone to damage and deformation, and the plug has two notches 39 on top, with specific assembly angle requirements. Whether assembling manually or pneumatically, the quality of the clamps and the assembly angle of the plug require manual inspection after assembly, which easily leads to missed or incorrect inspections, resulting in defective products and customer complaints. This plug pressing equipment incorporates a camera vision recognition system to photograph the assembled plug and, through corresponding algorithms, performs 100% inspection of the angle of the notches 39 and the integrity of the clamps 40, ensuring the quality of the assembled product.

[0040] like Figure 4 As shown, the steering knuckle positioning fixture includes a pressure head 30, a pressure head air detection pipeline 31, a steering knuckle positioning seat 32, fixing bolts 33, a positioning nylon block 36, a handle 37, and a steering knuckle positioning pin 38. The steering knuckle positioning fixture is connected to the upper end face of the fixture table 2 via four fixing bolts 33 around the steering knuckle positioning seat 32. The steering knuckle positioning seat 32 has a through hole in its center that engages with a cylindrical positioning pin with a central through hole. The positioning nylon block 36 is mounted on the steering knuckle positioning seat 32 and engages with the steering knuckle 35 to achieve angular positioning of the steering knuckle 35. The central hole of the steering knuckle 35 engages with the steering knuckle positioning pin 38 to achieve radial and axial positioning of the steering knuckle, thereby restricting the six degrees of freedom of the steering knuckle. The supporting beam 28 is mounted on the platform and is used to hold the pressure gauge 26. The pressure head air detection pipeline 31 is connected to the pressure gauge 26 through the equipment's air pipe. An air pipe is arranged at the bottom of the pressure head. When the plastic plug is placed completely horizontally and in contact with the air pipe, the pressure gauge reading is deemed qualified, and the equipment pressing can be started. The handle 37 is mounted on the steering knuckle positioning seat 32.

[0041] In one specific embodiment, the cable chain 25 is disposed on the inner wall of the platform and is used to secure the wiring and air pipes of the replaceable pressure head 27 and pressure head 30.

[0042] In one specific embodiment, the transition plate 4 and tooling positioning pin 6 of different sizes can be replaced to adapt to tooling of different sizes, thereby matching other types of products and realizing flexible pressing of multiple products by the equipment.

[0043] In one specific implementation, a barcode scanner 7 can also be used to input the QR code information reserved on the assembly parts, such as the plug, to achieve traceability of each plug.

[0044] In one specific embodiment, the safety light curtain 9 can be adjusted up and down according to the specific usage to achieve detection of different areas or to achieve complete coverage.

[0045] In one specific embodiment, the through-beam sensor on the sensor bracket 12 can be replaced with a vision sensor. The vision sensor can use a camera to capture images to prevent incorrect installation of different products and caps, thus preventing the wrong installation of other components. Alternatively, a proximity sensor can be used to prevent incorrect installation of components by setting a distance. Other types of sensors can also be installed to achieve the required detection functions, associated with the equipment, and detect the corresponding signals.

[0046] In one specific embodiment, the aviation connector 29 is located inside the barcode scanner 7. A through-beam sensor, a vision sensor, and a proximity sensor are arranged on the steering knuckle positioning fixture. The signal lines of these sensors can be integrated into the aviation connector. The aviation connector is connected to the aviation connector 29, and these signals can communicate with the PLC of the equipment. A corresponding program is set on the touch screen to monitor these signals. Example 2

[0047] This invention proposes a plastic plug pressing device. Taking the steering knuckle 35 to be pressed and the plastic plug 34 to be pressed as an example, its working process is as follows: Step 1: Place the steering knuckle positioning device onto the tooling positioning pin 6 on the workbench 2, and then tighten the four fixing bolts 33 to ensure the tooling is stably installed on the workbench 2. Connect the pressure head air detection pipeline 31 to the pressure gauge 26 through the air pipe interface.

[0048] Step 2: Place the steering knuckle 35 to be pressed onto the positioning fixture, and use the steering knuckle positioning pin 38 and positioning nylon block 36 to position it, restricting the workpiece's 6 degrees of freedom.

[0049] Step 3: Manually place the plastic plug 34 onto the pressure head 30 and position it so that it is in contact with the air tube on the pressure head. Observe the signal interface of the touch screen 13, which shows that the plug has been positioned.

[0050] Step 4: Take the barcode scanner 7 and scan the pre-engraved QR code on the steering knuckle 35 of the component to be pressed. Observe the display screen 13 interface. The QR code has been displayed on the interface. Then observe that the three-color warning light 14 is yellow. Place both hands on the two-hand start device 10 to start the equipment.

[0051] Step 5: After starting the equipment, motor 21 drives servo cylinder 22 to move downwards, and pressure head mounting seat 5 moves downwards along linear guide rail 24. Pressure head 30 moves downwards accordingly. During the pressing process, the real-time force value is transmitted from pressure head 30 to pressure sensor 23 and fed back to the equipment. The real-time pressure-displacement monitoring curve is displayed on touch screen 13. After plastic cap 34 is pressed into place, pressure sensor 23 reaches the set return force value, and motor 21 drives servo cylinder to move upwards, driving pressure head mounting seat to move upwards along linear guide rail 24. Pressure head 30 returns to the origin position of the equipment. At the same time that pressure sensor 23 reaches the set return force value, camera guard cylinder 18 moves to the left, driving camera guard 17 to move to the left. Camera light source 19 turns on to illuminate the end face of plastic cap 34 after the four claws 40 and steering knuckle 35 are assembled. Based on the set algorithm, it is determined whether the claws 40 of plastic cap 34 are intact and whether the assembly angle of notch 39 is correct. Figure 5 As shown. If the assembly is successful, the green indicator light (14) will illuminate; if the assembly is unsuccessful, the red indicator light will illuminate.

[0052] Step 6: Remove the steering knuckle 35 with the plastic plug 34 pressed on from the positioning fixture. At this point, start the cycle of this work process again from step two.

[0053] In some implementation cases, positioning fixtures for different steering knuckles or other products can be made, and pressure heads can also be made according to the parts to be installed, so as to realize flexible pressing of multiple products and multiple parts.

[0054] This invention proposes a plastic plug pressing device, which solves the problems of easy damage, easy omission, low assembly efficiency, poor assembly accuracy, easy error in assembly angle, and inability to monitor the assembly process when plastic plugs are manually assembled.

[0055] This invention includes a servo pressure electric cylinder control system, a pressure head air sensor, a pressure curve monitoring system, a camera vision recognition system, and a steering knuckle positioning fixture. After fixing the steering knuckle 35 to the equipment fixture, the plastic plug 34 is placed on the pressure head 30. The electric cylinder drives the pressure head to assemble the plastic plug 34 into the steering knuckle 35. The assembly process allows setting pressure and stroke parameters. During assembly, the real-time pressure curve is simultaneously uploaded to the equipment display. After assembly, the bottom camera system takes a picture, and visual recognition can determine whether the chuck 40 is properly assembled and whether the assembly angle of the plastic plug 34 is correct. The pressure electric cylinder control system can precisely control the pressing force and pressing speed of the plastic plug 34; the pressure curve monitoring system can be used to monitor the pressing parameters in real time and determine whether the pressing is qualified.

[0056] This invention features precise positioning, controllable pressing parameters, and a high degree of automation, effectively improving the pressing quality and batch assembly efficiency of steering knuckle plastic plugs. It is suitable for batch pressing production of different types of steering knuckles and other products, as well as different specifications of plastic plugs and other accessories.

[0057] As is known from common technical knowledge, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this invention or its equivalents are included in this invention.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of the present invention.
