Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing and automation equipment technology, specifically an installation device for production line fixture modification. Background Technology

[0002] In the field of automotive production line modification, fixture installation equipment is widely used in processes such as welding, assembly, and inspection. Typical fixture installation equipment consists of a main frame, fixture assemblies, a drive system, and a control system. The fixture assemblies are mechanically fixed to the main frame, the drive system adjusts the position of the fixtures, and the control system coordinates the actions of all components to complete the installation task. During operation, the equipment must meet the requirements of high-precision positioning, rapid adaptation, and stable operation, while also ensuring safety and adaptability to the on-site environment.

[0003] However, existing fixture installation equipment designs still have certain limitations. For example, a straight-rail side-panel conveyor vehicle with authorization announcement number CN103896032B, authorized on August 17, 2016, uses a suspended main structure with cylinders to achieve lifting and gripping functions. It is suitable for material handling between workstations in automotive welding lines and features low investment, high flexibility, and quick adaptation to different vehicle models. However, this technology is mainly designed for workpiece handling scenarios and does not address the fine-tuning and positioning functions in fixture installation, making it difficult to meet the high-precision installation requirements of ±0.1mm. Furthermore, this equipment lacks modular fixture interfaces and multi-degree-of-freedom adjustment mechanisms, resulting in insufficient adaptability to different fixture specifications. It cannot be used as a dedicated fixture installation device and cannot support the precise assembly requirements of complex fixture systems.

[0004] Furthermore, a flexible switching system layout structure for automotive welding, authorized by CN110788537B on February 1, 2022, achieves automatic switching of fixtures for various vehicle models through a combination of a sliding table and trolley mechanism with a fixture library, offering advantages in reducing modification time and costs. However, this system focuses on the overall layout and switching logic of the fixtures, without addressing the physical positioning, fine-tuning, and fixing operations of the fixtures during installation. Its fixture replacement relies on a seven-axis robot and preset tracks, lacking independent, portable, and flexibly deployable installation equipment. Especially in scenarios involving partial modifications to older production lines, it struggles to meet the rapid installation needs of space-constrained or non-standardized fixtures, and lacks dedicated safety protection design, posing certain operational risks.

[0005] The aforementioned problems indicate that while current technologies have made some progress in fixture switching and workpiece handling, significant shortcomings remain in areas such as fixture installation accuracy control, on-site adaptability, modular integration, and safety assurance. These shortcomings make it difficult to effectively meet the comprehensive requirements of "high-precision positioning + rapid adaptation + safety and reliability" during the fixture modification process in automotive production lines. Therefore, this utility model provides an installation device for production line fixture modification to overcome these deficiencies and offer a more intelligent, efficient, and adaptable solution for changing environments. Summary of the Invention

[0006] The purpose of this invention is to provide an installation device for production line fixture modification, addressing the shortcomings of existing fixture installation devices in terms of high-precision positioning, rapid adaptation, and safety assurance. Through modular design and multi-system integration, combined with optimized structural layout and control logic, it achieves precise adjustment, efficient adaptation, and safe operation of the fixture system.

[0007] This utility model provides an installation device for modifying production line fixtures, including a main support structure, a precision adjustment component, a power drive module, an intelligent control module, and a safety protection unit. The main support structure is made of high-strength alloy material, and its overall frame has been optimized through finite element analysis, possessing deformation resistance and load-bearing stability. The main support structure is equipped with multiple standardized interfaces for quick docking with external auxiliary devices or conveying equipment. These standardized interfaces employ a threaded nested connection method, achieving rapid fixation through a rotary locking mechanism to ensure a secure connection.

[0008] Furthermore, the precision adjustment assembly includes multiple independently operating clamping units, each connected to the main support structure via a sliding guide rail. The sliding guide rail adopts a dual-axis symmetrical design, with ball screws and linear bearings on both sides. The ball screws are driven by a stepper motor to adjust the horizontal position of the clamping unit; the linear bearings provide vertical guidance, working in conjunction with a hydraulic cylinder to complete the lifting and lowering of the clamping unit. The horizontal adjustment range of the clamping unit is ±60 mm, and the vertical adjustment range is ±120 mm, with an adjustment accuracy of 0.05 mm. The end of the clamping unit is equipped with an elastic chuck, the inner side of which is embedded with a rubber pad. The surface of the rubber pad is coated with an anti-slip coating to enhance clamping stability and reduce damage to the workpiece surface.

[0009] Specifically, the power drive module includes a hydraulic drive unit and an electric drive unit, which work in coordination through a central controller. The hydraulic drive unit consists of multiple miniature hydraulic cylinders, each employing a multi-layer sealing design: an outer wear-resistant rubber ring and an inner PTFE sealing ring, effectively reducing the risk of leakage. The hydraulic lines are made of stainless steel with a uniform diameter of 10 mm, and bend radii no less than four times the pipe diameter to prevent pressure loss during fluid transmission. The electric drive unit consists of a servo motor and a reducer. The servo motor is connected to a ball screw via a coupling, and the reducer has a transmission ratio of 1:20 to ensure that the output torque meets the load requirements of the clamping unit.

[0010] Furthermore, the intelligent control module includes a central processing unit (CPU), a signal acquisition unit, and a human-machine interface. The CPU incorporates a multi-threaded control algorithm, capable of processing feedback signals from sensors in real time and generating corresponding action commands. The signal acquisition unit includes a displacement sensor and a pressure sensor. The displacement sensor is mounted at the end of the ball screw to monitor changes in the position of the clamping unit, while the pressure sensor is embedded at the end of the piston rod of the hydraulic cylinder to detect the clamping force. The human-machine interface combines a touchscreen with physical buttons. The touchscreen displays the device's operating status, parameter settings, and fault alarm information, while the physical buttons allow for quick switching between operating modes, supporting both manual and automatic modes.

[0011] Specifically, the safety protection unit includes a protective fence, warning light strips, and emergency stop buttons. The protective fence, 1500 mm high, surrounds the equipment and is constructed from 50 mm diameter steel pipes welded together with a corrosion-resistant coating. The bottom of the fence features 10 mm thick anti-slip pads made of high-density polyurethane to enhance equipment stability. Warning light strips, using LED light sources with a brightness of at least 3000 lumens, are red and green to indicate dangerous and safe conditions, respectively. Emergency stop buttons are located at the four corners of the equipment, with a fluorescent coating for quick identification in low-light conditions.

[0012] Furthermore, the elastic chuck of the clamping unit is connected to the clamping arm via a quick-release mechanism. This quick-release mechanism employs a snap-fit ​​design, with a spring plate inside the snap-fit. The spring plate has a spring force coefficient of 5 Newtons / mm, ensuring convenience and reliability during chuck replacement. The clamping arm is connected to the sliding guide rail via a ball joint. The ball joint's swing angle range is ±15 degrees, used to compensate for possible angular deviations during clamping.

[0013] Furthermore, the hydraulic oil tank of the hydraulic drive unit is located at the bottom of the main support structure. The tank has a capacity of 20 liters and is equipped with an internal filter element with a pore size of 5 micrometers to filter impurities in the hydraulic oil. A level sensor is located on the top of the tank and is electrically connected to the central processing unit. When the hydraulic oil level is lower than a preset value, an alarm is displayed on the touch screen. The inlet and outlet of the hydraulic pipeline are connected to the hydraulic cylinder via quick-connect couplings. The quick-connect couplings have a self-locking design; they automatically lock after insertion and require an unlocking button to be pressed when removing them to prevent accidental dislodgement.

[0014] Furthermore, the signal acquisition unit of the intelligent control module also includes a temperature sensor installed inside the hydraulic oil tank to monitor changes in the hydraulic oil temperature. When the hydraulic oil temperature exceeds a preset upper limit, the central processing unit automatically reduces the operating frequency of the hydraulic cylinder and activates the cooling fan for cooling. The cooling fan is located on one side of the hydraulic oil tank, with seven aluminum alloy blades at a 30-degree angle to ensure sufficient airflow and low noise.

[0015] Furthermore, the protective fence posts are internally fitted with reinforcing ribs made of T-shaped steel, 8 mm thick, to enhance the overall rigidity of the fence. The fence mesh size is 50 mm × 50 mm, and the edges of the mesh are chamfered to prevent sharp parts from causing injury. The power supply line for the warning light strip uses a shielded cable with an outer aluminum foil shielding layer. The grounding resistance of the shielding layer is no more than 0.5 ohms to prevent electromagnetic interference from affecting the normal operation of the light strip.

[0016] Furthermore, the emergency stop button's circuit is designed with a dual-loop redundant structure. The main loop and the backup loop are respectively connected to different input ports of the central processing unit. When either loop triggers a stop signal, the equipment immediately stops operating. The button's contacts are made of silver alloy, with a contact resistance of less than 0.01 ohms, ensuring reliable signal transmission. The button's housing is made of flame-retardant ABS material with a flame-retardant rating of UL94-V0, enabling it to maintain stable performance in high-temperature environments.

[0017] Compared with existing technologies, the installation equipment for production line fixture modification provided by this utility model significantly improves the accuracy and efficiency of fixture installation through modular design and multi-system integration. The combination of sliding guide rails and ball screws enables high-precision adjustment of the clamping unit, while the coordinated operation of hydraulic and electric drives ensures the equipment's response speed and stability. The intelligent control module achieves intelligent operation of the equipment through multi-sensor data fusion, while the comprehensive coverage of the safety protection unit reduces operational risks. In addition, the design of the quick-release mechanism and standardized interface enhances the equipment's adaptability, enabling it to quickly adapt to fixtures of different specifications and meet the needs of various production scenarios.

The electrical drive unit consists of a servo motor and a reducer. The servo motor is connected to the ball screw 5 via a coupling. The reducer has a transmission ratio of 1:20 to ensure that the output torque meets the load requirements of the clamping unit 3.

[0027] The intelligent control module includes a central processing unit (CPU), a signal acquisition unit, and a human-machine interface (HMI).

[0028] The safety protection unit includes a protective fence, a warning light strip 8, and an emergency stop button 9. The protective fence, 1500 mm high, surrounds the equipment and is constructed from 50 mm diameter steel pipes welded together with a corrosion-resistant coating.

The button housing is made of flame-retardant ABS material with a UL94-V0 flame retardant rating, maintaining stable performance in high-temperature environments.

[0029] In practical applications, the operation process of the installation equipment for the production line fixture modification is as follows: First, the equipment is connected to the external auxiliary device or conveying equipment through the standardized interface on the main support structure 1, and quickly fixed by a rotary locking mechanism. Then, according to the size and shape of the workpiece, the initial position and clamping force parameters of the clamping unit 3 are set on the touch screen 10. After receiving the parameter settings, the central processing unit obtains feedback signals from the displacement sensor and pressure sensor through the signal acquisition unit, and adjusts the position and clamping force of the clamping unit 3 in real time. The horizontal movement of the clamping unit 3 is completed by a stepper motor driving the ball screw 5, while the vertical movement is achieved by a hydraulic cylinder in conjunction with a linear bearing 6. During clamping, the swing angle range of the ball joint is ±15 degrees to compensate for clamping angle deviation and ensure clamping stability. Simultaneously, a temperature sensor monitors the oil temperature inside the hydraulic oil tank 7. When the temperature exceeds the preset upper limit, the central processing unit automatically reduces the working frequency of the hydraulic cylinder and starts the cooling fan for cooling. During equipment operation, the warning light strip 8 switches between red and green lights according to the equipment status to remind the operator of the current safety situation. In case of emergency, the operator can press the emergency stop button 9 to immediately stop the equipment and ensure operational safety.

[0030] The above embodiments describe in detail the specific structure and operating principle of the installation equipment for production line fixture modification, covering the connection relationship, positional relationship and mutual cooperation relationship between various components, ensuring that those skilled in the art can implement the technical solution according to the contents of the specification.

[0031] To enable those skilled in the art to fully understand and implement this utility model, the following provides further supplementary explanations of the specific implementation principle of the installation equipment for production line fixture modification, in conjunction with a specific application scenario.

[0032] First, during the initial deployment phase of the equipment, the operator needs to connect the main support structure 1 to external auxiliary devices or conveying equipment through the standardized interfaces distributed around it. The standardized interfaces adopt a threaded nested connection method, and the design of the rotary locking mechanism ensures the firmness during the rapid fixing process. After the connection is completed, the operator inputs the workpiece size and shape parameters through the touch screen 10, and sets the initial position and clamping force of the clamping unit 3. After receiving the set parameters, the central processing unit activates the displacement sensor and pressure sensor in the signal acquisition unit to monitor the position change at the end of the ball screw 5 and the pressure value at the end of the hydraulic cylinder piston rod, respectively. These feedback signals are transmitted to the central processing unit in real time, and after being processed by the built-in multi-threaded control algorithm, instructions are generated to adjust the position and clamping force of the clamping unit 3.

[0033] Next, the clamping unit enters the precision adjustment stage. The clamping unit 3 moves horizontally along the sliding guide rail 2, an action driven by a stepper motor and ball screw 5. The dual-axis symmetrical design of the ball screw 5, combined with the linear bearing 6, provides stable guidance for the clamping unit 3, while achieving horizontal adjustment within a range of ±60 mm. In the vertical direction, the clamping unit 3, through a hydraulic cylinder and linear bearing 6, completes the lifting action, with an adjustment range of ±120 mm and an adjustment accuracy of 0.05 mm. The clamping arm is connected to the sliding guide rail 2 via a ball joint, with a swing angle range of ±15 degrees, compensating for possible angular deviations during clamping and ensuring clamping stability. Furthermore, the elastic chuck 4 is connected to the clamping arm via a quick-release mechanism. The spring coefficient inside the chuck is 5 N / mm, making chuck replacement both convenient and reliable. The rubber pad embedded inside the elastic chuck 4 is coated with an anti-slip coating, which not only enhances clamping stability but also reduces damage to the workpiece surface.

[0034] In the coordinated operation of the power system, the hydraulic drive unit and the electric drive unit work in unison through a central controller to meet the load requirements of different scenarios. The hydraulic pipelines are made of stainless steel, with bend radii no less than four times the pipe diameter to avoid pressure loss during fluid transmission. The hydraulic oil tank 7 is located at the bottom of the main support structure 1, and its internal filter element has a pore size of 5 micrometers to filter impurities in the hydraulic oil. A level sensor is installed on the top of the tank; when the hydraulic oil level is lower than a preset value, the touchscreen 10 will display an alarm. Simultaneously, the servo motor is connected to the ball screw 5 via a coupling, and the reducer's transmission ratio is 1:20 to ensure that the output torque meets the load requirements of the clamping unit 3. The hydraulic cylinder employs a multi-layer sealing design, with an outer wear-resistant rubber ring and an inner PTFE sealing ring, effectively reducing the risk of leakage.

[0035] During the operation of the intelligent control module, the central processing unit adjusts the movement of the clamping unit 3 in real time based on feedback signals from the displacement and pressure sensors. A temperature sensor is installed inside the hydraulic oil tank 7 to monitor changes in the hydraulic oil temperature. When the hydraulic oil temperature exceeds a preset upper limit, the central processing unit automatically reduces the operating frequency of the hydraulic cylinder and activates the cooling fan for cooling. The cooling fan blades are made of aluminum alloy, with seven blades and a blade angle of 30 degrees, ensuring sufficient airflow and low noise. The human-machine interface combines a touchscreen 10 with physical buttons, supporting both manual and automatic operation modes, allowing operators to quickly switch between modes.

[0036] Under the protection of the safety protection unit, the warning light strip 8 switches between red and green lights according to the status during equipment operation, reminding operators of the current safety situation. A protective fence, 1500 mm high, surrounds the equipment and is constructed from 50 mm diameter steel pipes with a corrosion-resistant coating. The bottom of the protective fence features 10 mm thick anti-slip pads made of high-density polyurethane, enhancing the equipment's stability. Emergency stop buttons 9 are located at the four corners of the equipment, with a fluorescent coating for easy identification in low-light conditions. The emergency stop button 9 has a dual-circuit redundant structure; the main circuit and backup circuit are connected to different input ports of the central processing unit. When either circuit triggers a stop signal, the equipment immediately stops operating, ensuring operational safety.

[0037] Finally, during the actual fixture installation process, clamping unit 3, through the coordinated work of the aforementioned modules, achieved the goals of high-precision positioning, rapid adaptation, and safe operation. For example, in a fixture modification scenario for an automotive production line, after the equipment connects to the conveying device via a standardized interface, clamping unit 3 quickly adjusts to the target position according to preset parameters. The elastic chuck 4 stably clamps the fixture and performs fine adjustments, ultimately completing the precise installation of the fixture. The entire process demonstrates the equipment's comprehensive advantages in high-precision positioning, rapid adaptation, and safety assurance, significantly improving fixture installation efficiency and quality.
