Description

Technical Field

[0001] This utility model relates to the field of shock absorber components, specifically to a production line for processing shock absorber oil reservoirs. Background Technology

[0002] As an important component for ensuring comfort during vehicle operation, the shock absorber works by filling a reservoir with oil, driving the piston rod to move the piston up and down in the reservoir, while the oil flows through the valve, thus buffering the vibrations during vehicle operation.

[0003] The oil reservoir is a major component of the shock absorber. The traditional processing flow mainly includes: selecting cold-rolled steel welded steel pipe as the base material, ensuring the assembly accuracy of the two ends of the cylinder with the oil seal and bottom cover through necking and machining, and performing rolling lettering on the cylinder body (the rolling lettering on the cylinder body is mainly used for identification and functional assistance. The identification includes the shock absorber model, batch number, production date, etc., which facilitates quality traceability and assembly matching. The functional assistance markings can guide subsequent assembly and improve the overall production and assembly efficiency of the shock absorber).

[0004] However, the current production of oil storage tanks mostly relies on manual loading and unloading operations and single-machine operation. Manual operation leads to material mixing problems and low operating efficiency, making it difficult to meet the needs of modern automated production lines. Furthermore, when manually machining both ends of the cylinder on a lathe, secondary positioning is required, and accumulated errors cause the cylinder's coaxiality to exceed tolerances, seriously affecting the sealing performance of the vibration damper. On the other hand, the single-machine operation mode has a large footprint, high energy consumption (more than 20% higher than automated production lines), and the splashing of cutting fluid causes serious pollution to the working environment. These problems result in a 15%-20% reduction in product qualification rate and restrict the intelligent upgrading of the production line. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this application provides a production line for processing shock absorber oil reservoirs. This shock absorber oil reservoir processing line utilizes a specific structure to automatically perform loading and unloading operations, and inspects the reservoir body during loading to prevent material mixing. During machining, both ends of the reservoir body can be processed simultaneously to ensure the coaxiality of the reservoir body meets usage requirements. Furthermore, the automated production line has a compact layout, effectively reducing the floor space required, and the enclosed machine tool processing reduces cutting fluid splash pollution, contributing to a cleaner work environment.

[0006] The technical solution of this application is as follows:

[0007] A shock absorber oil reservoir processing production line includes a feeding and distributing device, a double-head CNC lathe, a lettering device, a feeding robot, and a transferring and unloading robot. The feeding and distributing device includes a machine base, a material trough, a detection device, and a distributing device. The material trough contains a feeding device for transferring the cylinders from the trough to the detection device. The detection device includes a length detection mechanism and an outer diameter detection mechanism. The length detection mechanism detects the length of the cylinder, and the outer diameter detection mechanism detects the outer diameter of the cylinder. The distributing device transfers the cylinders from the detection device to a distributing table. The feeding robot transfers qualified cylinders to the double-head CNC lathe and unqualified cylinders to a scrap bin. The transferring and unloading robot includes a transferring robot and an unloading robot. The transferring robot transfers the cylinders processed on the double-head CNC lathe to the lettering device, and the unloading robot transfers the lettered cylinders from the lettering device to an unloading bin.

[0008] Compared with existing technologies, the shock absorber oil reservoir processing production line of this application uses a detection device in the feeding and sorting device to detect the cylinder body. A loading robot transfers the qualified cylinder body to a double-headed CNC lathe, or transfers the unqualified cylinder body to a scrap bin to avoid mixing. The double-headed CNC lathe synchronously processes both ends of the cylinder body to ensure that the coaxiality of the cylinder body meets the usage requirements. A transferring robot transfers the processed cylinder body from the double-headed CNC lathe to a lettering device, and an unloading robot transfers the lettered cylinder body from the lettering device to an unloading bin. This achieves automated production of the shock absorber oil reservoir. The automated production line, with its compact layout, effectively reduces the floor space required. The enclosed machine tool processing reduces cutting fluid splash pollution, contributing to a cleaner work environment.

[0009] As an optimization, in the aforementioned shock absorber oil reservoir processing production line, the feeding device includes a set of forward-inclined, stepped fixed plates, with a liftable pusher plate between adjacent fixed plates. When the pusher plate is at its lowest point, its top is lower than the top of the fixed plate behind it; when the pusher plate is at its highest point, its top is higher than the top of the fixed plate in front of it. This stepped feeding structure enables efficient automated operation; and compared to traditional vibratory feeder feeding, the stepped feeding structure effectively avoids the noise and surface scratches associated with vibratory feeder feeding.

[0010] As an optimization, in the aforementioned shock absorber oil reservoir processing production line, the material distribution device includes a translation mechanism, a lifting mechanism, and a pallet. The pallet is mounted on the lifting mechanism and is used to support the cylinder after it has been inspected in the inspection device. The lifting mechanism is mounted on the translation mechanism and is used to drive the pallet to move up and down. With this structure, after the cylinder has been inspected, the translation mechanism extends, the lifting mechanism rises, so that the pallet lifts the cylinder, the translation mechanism retracts, and the lifting mechanism descends, placing the cylinder on the material distribution table. This automation process is simple and less prone to errors.

[0011] As an optimization, in the aforementioned shock absorber oil reservoir processing production line, both the translation mechanism and the lifting mechanism are cylinders. Cylinders are characterized by their simple structure and convenient maintenance.

[0012] As an optimization, the aforementioned shock absorber oil reservoir processing production line is equipped with V-grooves on both the material distribution table and the pallet. This structure allows the cylinder to remain stationary after placement, facilitating the transfer of the material distribution device and the gripping of the robotic arm.

[0013] As an optimization, in the aforementioned shock absorber oil reservoir processing production line, a limiting plate is provided on the material trough, and a screw is provided on the limiting plate. The screw is screwed to the side wall of the material trough, and a handwheel is provided at the end of the screw extending out of the material trough. With this structure, the position of the limiting plate can be adjusted by rotating the handwheel, thereby adjusting the usable width of the material trough and limiting the position of the cylinder placed therein, which facilitates the loading operation.

[0014] As an optimization, in the aforementioned shock absorber oil reservoir processing production line, both the loading robot and the unloading robot are gantry robots. Gantry robots are characterized by high efficiency, high reliability, and convenient maintenance, and they occupy less space, making the production line layout more compact.

[0015] As an optimization, in the aforementioned shock absorber oil reservoir processing production line, both the length detection mechanism and the outer diameter detection mechanism are displacement sensors. Displacement sensors can provide high-precision measurement results, ensuring the accuracy of the detection; moreover, displacement sensors can be directly purchased, resulting in low cost.

[0016] As an optimization, in the aforementioned shock absorber oil reservoir processing production line, the lettering device is a servo lettering machine. Servo lettering machines offer high precision and stability, are relatively simple to install and use, and are easy to maintain; moreover, servo lettering machines can be directly purchased.

[0017] As an optimization, the aforementioned shock absorber oil reservoir processing production line includes two double-head CNC lathes, located on either side of the feeding and distributing device. This structure allows for the processing of two reservoirs at once, improving production efficiency. Attached Figure Description
