Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive equipment manufacturing, specifically to a method for automatically drying a vehicle axle housing after soaking and cleaning. It is a method that can solve the problems of dampness and rust, dust adsorption, and difficulty in long-term storage of axle housings, and improve the quality of axle housings. Background Technology
[0002] As a core load-bearing component of a vehicle's transmission system, the manufacturing process of the automotive axle housing (drive axle housing) directly affects the vehicle's safety, durability, and performance. With the automotive industry moving towards lightweight, high-strength, and long-life designs, the cleaning, storage, and drying processes of the axle housing have become critical quality control points. Dedicated axle housing drying workstations are a vital link in the intelligent and green transformation of automotive manufacturing processes. Their technological innovation not only improves product quality and production efficiency but also contributes to the industry's sustainable development goals. As an important carrier of modern drying technology, dedicated axle housing drying workstations are gradually becoming key equipment for improving quality and efficiency in various industries, with reliable drying capabilities providing quality assurance for subsequent processes. With advancements in manufacturing technology, dedicated axle housing drying workstations are developing towards greater intelligence and energy efficiency, significantly improving drying efficiency and quality, and providing more comprehensive solutions for automotive parts manufacturing. Utility Model Content
[0003] As a key component of the vehicle's transmission system, the automotive axle housing retains contaminants such as cutting fluid, oil, metal shavings, and dust on its surface after machining, welding, polishing, and grinding. Traditional methods of soaking and washing followed by natural air drying have several problems, including: low efficiency (natural drying takes several hours and the ambient temperature is uncontrollable, severely impacting production efficiency); environmental limitations (highly dependent on weather conditions, with seasonal and environmental changes, such as humid or rainy days, affecting axle housing quality); secondary contamination risks (damp surfaces easily attract dust, develop water stains, and rust); quality risks (residual moisture may lead to decreased quality in subsequent processes, resulting in unstable quality management, with the most serious issue being rusting of the axle housing); and poor storage conditions (without effective treatment, prolonged storage can significantly shorten the product's lifespan).
[0004] This invention aims to provide a device for automatically drying vehicle axle housings after soaking and cleaning. This device overcomes the shortcomings of the prior art and features high efficiency, is unaffected by environmental factors, effectively prevents secondary pollution, improves the quality of subsequent processes, and is beneficial for storage.
[0005] The technical solution of this utility model is as follows: A device for automatically drying vehicle axle shells after soaking and cleaning, comprising a left drying chamber, a right drying chamber, a traction mechanism, and axle shell material frame carts; characterized in that: the left and right drying chambers are symmetrically arranged, with a slide rail in the middle; the traction mechanism is mounted on the slide rail, and a set of axle shell material frame carts are fixedly mounted at both ends of the traction mechanism, and the traction mechanism can move left and right along the slide rail; when the traction mechanism moves to the left end of the slide rail, the axle shell material frame cart at its left end is sent into the left drying chamber, and the axle shell material frame cart at its right end is located outside the right drying chamber; when the traction mechanism moves to the right end of the slide rail, the axle shell material frame cart at its right end is sent into the right drying chamber, and the axle shell material frame cart at its left end is located outside the left drying chamber.
[0006] The traction mechanism includes a traction platform, a servo motor, limit switches, a cable chain, and a rack. A set of limit switches is provided at each end of the slide rail. The traction platform is mounted on the slide rail via a slider. The servo motor is mounted on the traction platform, and a connecting plate bracket is mounted on the traction platform and connected to the cable chain. The output shaft of the servo motor meshes with the rack on the side of the slide rail after being redirected by a bevel gear.
[0007] The axle shell frame car includes a base and an axle shell support. The base is placed on a traction platform. Multiple sets of axle shell supports are provided above the base.
[0008] The base is equipped with wheels at the four corners of its bottom. When the bridge shell material frame trolley moves with the traction platform, the wheels are always in contact with the ground.
[0009] The doors of the left and right drying rooms are located on the sides of their corresponding slide rails and are opened and closed by telescopic cylinders; the bottom of the doors is provided with opening slots at both ends of the corresponding traction mechanism; a set of warm air blowers is respectively installed in the middle of the top of the left and right drying rooms, and the air blowing direction of the warm air blowers is vertically downward.
[0010] The top surface of the traction platform is equipped with an anti-slip pedal.
[0011] The tops of the left and right drying chambers are equipped with anti-slip mats.
[0012] The drying room door is equipped with a pull handle for manually opening and closing the drying room.
[0013] The doors, left drying room, and right drying room are all made of insulation panels.
[0014] The slide rail is equipped with a slide rail slider guard plate.
[0015] The bridge shell material frame cart is categorized by large, medium, and small bridge shells and can be manually switched at will; the bridge shell drying workstation is laid out with three workstations: A, B, and C. A and C are drying positions, and B is the manual loading / unloading position for bridge shells. After the manual worker has filled the No. 1 material frame cart with the soaked and cleaned bridge shells, the worker presses the "complete" button, and the No. 1 bridge shell material frame cart will be automatically transported to the A drying position. Figure 3 As shown in the diagram, the workpiece is manually loaded and unloaded, and the next workpiece to be dried is loaded. After assembly, once the drying operation at drying station A is completed, the traction mechanism reverses direction, pulling the ① material frame car to manual station B for disassembly and replacement, while the ② material frame car is simultaneously sent to drying station C for drying. This process is repeated in a cycle.
[0016] The drying time is generally 10-15 minutes, which is basically the same as the disassembly and assembly time of the workpiece. This allows for continuous operation of the entire process, greatly improving work efficiency. In addition, the intermittent drying operation also allows the heater to rest intermittently, preventing overheating and damage, and extending the service life of the heater.
[0017] The beneficial effects of this utility model are as follows:
[0018] This utility model relates to a device for automatically drying vehicle axle housings after soaking and cleaning. It features convenient operation, safety and reliability, improved efficiency, controllable temperature, adjustable wind speed, and uniform drying. The drying chamber employs a warm air circulation design, combining warm air circulation, temperature control, and airflow adjustment technologies. The warm air blowers are arranged from top to bottom, evenly distributing the warm air source throughout the chamber. Finally, heat rises from the bottom, creating a continuous cycle that prevents incomplete drying of the axle housing in hard-to-reach areas and improves drying efficiency. The axle housing drying workstation uses a traction mechanism for automatic transport of the axle housings. Drying time is controlled by a time relay, allowing for flexible production rhythm customization. After drying, the axle housing traction mechanism automatically transports the axle housings from the drying chamber to a designated safe working position for manual lifting / loading, preventing workers from entering hazardous areas. The superior drying process enhances rust prevention and reduces after-sales maintenance issues. Attached Figure Description
