Excavator product structure and Design Outsourcing

product mix

Anhui excavator generally by the power device, transmission device, walking device and working device, etc.. Principle: above or below the surface of bearing machine material with bucket digging, earthmoving machinery transport and loading or unloading of vehicles to the yard. Install stripping or mineral products and apply it to row self-propelled mining machinery unloading unloading locations from the work surface with a shovel bucket. History: the first manual machine has been published for more than 130 years of history, during the process of the gradual development of the hydraulic excavator by steam driven bucket rotary excavator to power driven and internal combustion engine driven rotary excavator, application of Mechatronics technology.

Due to the application of hydraulic technology, 1940s has been installed in the tractor equipped with a backhoe hydraulic excavator suspension, in early 1950s, and have been developed in the mid towed rotary hydraulic excavators and crawler hydraulic excavator. The hydraulic excavator is used in the initial stage of the hydraulic pressure technology, the lack of hydraulic components used in various working conditions, the manufacturing quality is not stable, and the supporting parts are not complete. From 1960s onwards, the hydraulic excavator into the promotion and booming stage, the national excavator manufacturing plants and varieties increased rapidly, the output soared. 1968-1970 years, the hydraulic excavator production has accounted for 83% of the total output of excavators, is now close to 100%.

Design Outsourcing

Definition

Small excavator design outsourcing services: refers to the enterprise customers to hire professional small excavator design service providers, to provide customers with a full range of CMD technical services, to enhance the enterprise technology advantage, reduce the development costs of the behavior.

classification

Design: application of mature design experience or feasible new technology, design of new type of small excavator, including functional design and mechanism design.

Upgrade design: Based on experience and technology development of the existing small excavator design update, in order to improve performance, reduce manufacturing costs or reduce operating costs.

Derivative design: amended or part of the additions and deletions to adapt to the new needs of the existing small excavator, thus developed is different from the standard type of derivative products.

Series design: in a small excavator as female parent, a series of similar design with the same shape and function, but the power, tonnage, the size has a series of different products.

development procedure

A demand analysis. According to the functional, performance, operating environment and other factors, with the customer to develop a detailed user requirements specification, and then determine the development goals.

Two, preliminary scheme design. According to the requirement analysis, plan formulation, including function and parameter setting, basic calculation, drawing the preliminary three-dimensional total work, and then the preliminary examination with the customer.

Three, detailed plan design. Listen to the first instance, the implementation of the programme design. Modify the 3D model layout, drawing three-dimensional parts, finite element analysis and dynamic simulation of structural components. And then with customers for the two review.

Four, the final plan and drawing. Listen to the second opinion, modify the program design. Drawing plan (such as parts, assembly drawings, assembly drawings, painting, etc.), out of the list of parts, wearing parts list.

Five, the production of all technical documents, including propaganda and technical samples, product use manual.
