The Application And Production Scheme of Zero Position System

Zero point positioning system is used for all kinds of machining centers, and can also be used in the automotive industry, aviation industry, construction machinery industry, transportation industry, etc., and in the motor industry and military industry is also widely used. The production of a zero-point positioning system can take a flexible processing line or accompanying plate-fixture program production, the production of a zero-point positioning system is complete, and the quality is guaranteed, and the following details for everyone to introduce.

First, the application of a zero-positioning system
 
1, automobile: engine, automobile mold, gearbox, hub machine tool: metal cutting processing, equipment supporting, equipment production.
 
2. Aviation: aircraft engines, aircraft parts.
 
3, construction machinery: excavator, bulldozer, roller, crane, rock drill, etc.
 
4. Transportation: high-speed trains.
 
5. Wind power industry: Wind power generation.
 
6, pump, valve: pump, valve manufacturing.
 
7, motor: motor production.
 
8. Ship: Ship manufacturing.
 
9. Motorcycle: Motorcycle production.
 
10, military: military production, equipment manufacturing.
 
11, automatic production line: body welding line.
 
Second, the production scheme of zero positioning system
 
1, flexible processing line
 
Flexible manufacturing technology refers to manufacturing equipment based on highly flexible computer numerical control machine tools to achieve multi-variety and mass production. Flexible manufacturing technology has been proposed for more than 40 years, its connotation is richer and richer, the scope of application has been developed from the original multi-variety, small-batch production field to restricted varieties can be mass-produced field. The concept of flexible manufacturing technology is no longer a simple manufacturing technology, but in a broader sense is the technical component of advanced manufacturing system mode.
 
At present, in the automobile manufacturing industry, the production of cylinder blocks, cylinder head, and other box parts with an output of more than 300,000 is generally used in the flexible processing line (FML) or processing machine automatic line. The flexible machining line is generally composed of a conventional machining center (its function can be increased as needed), which is directly used for loading and unloading of the machine tool with the high-speed conveyor manipulator. With the development of equipment, tools and various auxiliary technologies, the application of flexible machining line in mass production tends to be mature, but it is only suitable for flexible production lines in large quantities and few varieties of production. In order to increase the flexibility of the production line and adapt to the processing of parts with different dimensions, the accompanying plate-fixture scheme has emerged.
 
2. Accompanying pallet - fixture scheme
 
Trailing plate fixtures are a class of fixtures used in automatic and flexible manufacturing systems. It not only completes the positioning and clamping of the workpiece but also acts as a carrier to transfer the workpiece between the machine tools. After being transferred to the machine tool of the next process, it should be able to accurately position and reliably clamp on the machine tool. There are many accompanying fixtures on a production line, each accompanying fixture goes through the whole process of the production line with the workpiece, and then the processed workpiece is removed, the new workpiece to be processed is installed, and the cycle is used. Because the workpiece is directly loaded by the clamping fixture of the machine tool up and down the flexible processing line, when the clamping fixture installed on the machine tool cannot meet the clamping requirements of the workpiece change, it is necessary to manually replace the pallet (with the fixture) of different parts, that is, the pallet - fixture of different parts is also different.
 
The previous accompanying plate-clamp form belongs to the category of special fixtures. The parts are installed on the accompanying pallet, and the conveying and positioning clamping of the parts are completed through the pallet. The accompanying pallet is both a fixture and a conveying medium, and the size is generally larger than the part itself; In order to ensure good rigidity when cutting, steel is generally used as a fixture material, and the quality is even heavier than the part itself.
