| Design Points Of Special Fixtures
The fixture design is generally carried out in accordance with the specific requirements of a certain process after the machining process of the parts is formulated.
DALIAN, China - Dec. 27, 2021 - PRLog -- - The Basic Principles Of Fixture Design
- Satisfy the stability and reliability of workpiece positioning during use
- There is sufficient load or clamping force to ensure the processing of the workpiece on the fixture
- Satisfy simple and fast operation in the clamping process
- The fragile parts must be of a structure that can be replaced quickly, and it is best not to use other tools when the conditions are sufficient.
- Satisfy the reliability of repeated positioning of the fixture during adjustment or replacement
- Avoid complex structure and high cost as much as possible
- Use standard parts as component parts as much as possible
- Form the systemization and standardization of the company's internal products
Basic Knowledge Of Fixture Design
A good machine tool fixture must meet the following basic requirements: - To ensure the machining accuracy of the workpiece, the key to ensuring the machining accuracy is to correctly select the positioning datum, positioning method and positioning components. If necessary, positioning error analysis is also required, and attention must be paid to the structure of other parts in the fixture to the machining accuracy The influence of this to ensure that the fixture can meet the machining accuracy requirements of the workpiece.
- The complexity of the special fixture for improving production efficiency should be adapted to the production capacity, and various fast and efficient clamping mechanisms should be adopted as far as possible to ensure convenient operation, shorten auxiliary time, and improve production efficiency.
- The structure of the special fixture with good process performance should be simple and reasonable, which is convenient for manufacturing, assembly, adjustment, inspection, maintenance, etc.
- Good use performance. The fixture should have sufficient strength and rigidity, and the operation should be simple, labor-saving, safe and reliable. Under the premise that objective conditions permit and are economical and applicable, pneumatic, hydraulic and other mechanized clamping devices should be used as much as possible to reduce the labor intensity of the operator. Tooling fixtures should also be convenient for chip removal. When necessary, a chip removal structure can be set to prevent chips from destroying the positioning of the workpiece and damaging the tool, and to prevent the accumulation of chips from bringing a lot of heat and causing deformation of the process system.
