Description

Technical Field

[0001] This utility model relates to the field of assembly equipment technology, specifically to an automatic servo tightening assembly device. Background Technology

[0002] In the manufacturing production system, manual assembly occupies an irreplaceable and crucial position. This stage highly relies on the superb skills and meticulous work attitude of skilled workers. In actual operation, workers must strictly adhere to process requirements and product standards to precisely assemble various components into a complete product. This not only demands that workers possess excellent operational skills but also requires them to maintain a high degree of responsibility and patience at all times. Only in this way can the accuracy of each assembly step be ensured, ultimately achieving product quality standards.

[0003] However, in long-term and high-intensity production processes, manual assembly reveals many undeniable drawbacks. Due to prolonged repetitive work, workers are prone to fatigue, leading to a gradual decline in work efficiency. At the same time, quality control during manual assembly faces significant challenges. Although workers employ rigorous inspection and testing to ensure each assembly step meets quality standards, the limitations of manual operation make it difficult to completely avoid problems, such as accidental damage to parts during assembly and inconsistent assembly precision.

[0004] As the manufacturing industry demands increasingly higher production efficiency and product quality, the drawbacks of manual assembly have become increasingly apparent, making it difficult to meet the industry's development needs. Therefore, developing equipment that can overcome the shortcomings of manual assembly has become an urgent priority. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned problems and provide an automatic servo tightening assembly device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic servo tightening assembly device includes:

[0008] The lifting drive assembly includes a lifting motor and HGH series guide rails and sliders; the lifting motor is driven to connect with the HGH series guide rails and sliders.

[0009] Furthermore, the lifting motor is rigidly connected to the slider via bolts and drives the slider to move linearly along the HGH series guide rails. The lifting motor is the power source for the equipment to achieve vertical movement. It works in conjunction with the HGH series guide rails and sliders to drive related components to move up and down along the guide rails, thereby adjusting the height of components such as assembly fixtures. This allows the assembly fixtures to be precisely aligned with the product's assembly position, providing suitable height conditions for subsequent assembly operations.

[0010] HGH series guide rails and sliders provide stable and reliable guidance for vertically moving components in equipment. Working in conjunction with the lifting motor, they ensure the accuracy and stability of related components during lifting, effectively preventing misalignment of assembly fixtures during vertical movement, thereby ensuring the accuracy of the entire assembly process.

[0011] Furthermore, the power assembly is tightened, including a servo motor, a reducer, and a spindle bearing sleeve, and the servo motor, reducer, and spindle bearing sleeve are sequentially connected in a transmission manner;

[0012] The output shaft of the servo motor is connected to the input shaft of the reducer via a coupling; the output shaft of the reducer is connected to the main shaft bearing sleeve via a key.

[0013] As the core power source of the tightening power assembly, the servo motor can output precise speed and torque. Working in conjunction with the reducer and spindle bearing sleeve, it transmits power to subsequent components, providing stable and precise rotational power for the tightening assembly of the product, ensuring the accuracy and consistency of the tightening action during assembly.

[0014] The speed reducer is installed between the servo motor and the spindle bearing sleeve. Its main function is to reduce the output speed of the servo motor and increase the torque. Through the action of the speed reducer, the spindle bearing sleeve can obtain power parameters that are more suitable for tightening the product, so that the tightening operation can be carried out with appropriate force and speed during assembly, avoiding product damage or loose assembly caused by improper power.

[0015] The spindle bearing, driven by a servo motor and reducer, rotates and is a key component for the assembly fixture to perform tightening actions. It transmits power to the assembly fixture, causing it to rotate and thus completing the tightening assembly of the product. Its rotational accuracy directly affects the product assembly quality.

[0016] The control components include a touch screen, which is electrically connected to the lifting motor;

[0017] The touchscreen is electrically connected to the lifting motor and is a crucial component for operator-equipment interaction. Operators use the touchscreen to set equipment parameters, such as the lifting motor's speed and height, enabling them to control the equipment's operating status and complete assembly tasks intuitively and conveniently.

[0018] Furthermore, the positioning and support components include a central positioning clamp mechanism, an assembly platform lifting support plate, and an HE series pneumatic lifting mechanism, with the HE series pneumatic lifting mechanism being driven to connect with the assembly platform lifting support plate.

[0019] The center positioning clamping mechanism is used to position and clamp the product, ensuring that it remains in a stable and accurate position during assembly. Precise positioning and secure clamping prevent product displacement during assembly, guaranteeing high-precision assembly.

[0020] The assembly platform lifting support plate, in conjunction with the HE series pneumatic lifting mechanism, serves to support and adjust the product height during assembly. When the HE series pneumatic lifting mechanism drives it to rise or fall, it ensures that the product and assembly fixture are in a suitable relative position, facilitating assembly operations.

[0021] The HE series pneumatic lifting mechanism is connected to the lifting support plate of the assembly platform. It uses gas pressure to provide power to control the lifting and lowering of the lifting support plate of the assembly platform, thereby adjusting the height of the product and making it precisely match the assembly tooling to complete the entire assembly process.

[0022] Furthermore, it also includes a conductive ring and an assembly tooling connector; the top end of the conductive ring is connected to the spindle bearing sleeve, and the bottom end is connected to the assembly tooling connector.

[0023] The top of the conductive ring is connected to the main shaft bearing sleeve, and the bottom is connected to the assembly tooling connector, serving a dual function of conducting electricity and connecting components. On the one hand, it provides a current path for components in the equipment that require power transmission, ensuring the normal operation of the equipment; on the other hand, it connects different components, making them form a whole in terms of mechanical structure.

[0024] The assembly tooling connector connects a conductive ring at one end and a product positioning sensor and assembly tooling at the other end. It serves as a connector and support in the mechanical structure, ensuring accurate relative positioning between related components, guaranteeing coordinated operation of all components, and enabling the assembly tooling to perform assembly tasks in the correct position.

[0025] Furthermore, it also includes a product positioning sensor and an assembly fixture; the top end of the product positioning sensor is connected to the assembly fixture connector; the other end is connected to the assembly fixture; and the assembly fixture is linked with the spindle bearing sleeve.

[0026] The product positioning sensor is connected at one end to the assembly fixture connector and at the other end to the assembly fixture itself. It is primarily used to detect whether the product is properly positioned. When the product is detected to be in the correct position, it sends a signal to the equipment control system, triggering subsequent assembly actions. This ensures that assembly is performed only when the product is correctly positioned, improving the accuracy and reliability of the assembly process.

[0027] The assembly fixture is linked to the spindle bearing sleeve and rotates under the drive of the spindle bearing sleeve. It acts directly on the product and is the executing component that completes the product assembly. It achieves the tightening operation of the product through rotation, and its structure and performance directly affect the assembly quality and efficiency of the product.

[0028] The advantages of this utility model are:

[0029] 1. In this utility model, the lifting motor of the equipment works in conjunction with the HGH series guide rails and sliders to precisely adjust the height of the assembly platform, which houses the servo motor, reducer, and other components, allowing the assembly fixture to be accurately aligned with the valve position on the product. The servo motor drives the main shaft bearing sleeve via the reducer, causing the assembly fixture to rotate and complete the valve assembly. The entire process is characterized by precise positioning and stable operation. Compared to manual assembly, this significantly increases assembly speed, reduces manual operation time, ensures stable product quality, and effectively improves production efficiency.

[0030] 2. This utility model features automation capabilities. The central positioning clamping mechanism and the HE series pneumatic lifting mechanism work together to automatically complete a series of operations, including product positioning, clamping, assembly, and release, greatly reducing manual intervention. Workers only need to set parameters and place the product via a touchscreen in the early stages, reducing direct contact with dangerous parts, lowering the risk of workplace accidents, reducing the physical burden on workers, improving the working environment, and lowering the company's labor costs.

[0031] 3. The modern automatic servo system equipped in this utility model, combined with a touch screen, allows for flexible adjustment of assembly processes and parameters. It effectively adapts to the assembly needs of valves of different models and specifications, demonstrating high flexibility and scalability, and providing strong support for enterprises to carry out diversified production. Furthermore, the equipment can record data for each assembly, including time, parameters, and results, facilitating quality traceability and helping enterprises continuously improve their production processes.
