Principles and Basic Principles of Tooling and Fixture Design

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. So what is the design principle of tooling and fixtures? When formulating the process, we should fully consider the possibility of fixture realization. When designing tooling and fixtures, you can also propose amendments to the process if necessary.

Before tooling and fixture design, you need to prepare these materials in advance: design notices, finished parts drawings, blank drawings and process routes and other technical materials, understand the processing technical requirements of each process, positioning and clamping schemes, the processing content of the previous process, and the status of the blank. Machine tools, cutting tools, inspection measuring tools, machining allowances and cutting parameters used in processing.

What is the design principle of tooling and fixture

1. Satisfy the stability and reliability of workpiece positioning during use;

2. There is sufficient load or clamping force to ensure the processing of the workpiece on the fixture;

3. Satisfy simple and fast operation in the clamping process;

4. The fragile parts must be of a structure that can be quickly replaced, and other tools are not required when the conditions are sufficient;

5. Satisfy the reliability of repeated positioning of the fixture during adjustment or replacement;

6. Avoid complex structure and high cost as much as possible;

7. Choose standard parts as component parts as much as possible;

8. Form the systemization and standardization of the company's internal products.

The design quality of tooling fixtures should be measured by whether it can stably guarantee the processing quality of the workpiece, high production efficiency, low cost, convenient chip removal, safe operation, labor-saving, easy manufacturing, and easy maintenance. The above is about the specific matters of fixture design, if you want to know more, you can pay attention to our website.

Basic principles of fixture design

The basic principle of tooling and fixture design is to design the positioning structure of the tooling according to the requirements of the actual situation of the product. Pay attention to the convenience of product access and the protection of the product appearance. The positioning block and the auxiliary positioning device contacting the product should use white glue as much as possible. Non-metallic materials.

1. Satisfy the stability and reliability of workpiece positioning during use;

2. There is sufficient load bearing or clamping force to ensure the construction process of the workpiece on the fixture;

3. Satisfy the simple and fast operation in the clamping process;

4. Vulnerable parts must be of a structure that can be quickly replaced

5. Satisfy the reliability of repeated positioning of the fixture during adjustment or replacement;

6. Avoid complex structure and high cost as much as possible;

7. As far as possible, select reliable quality standard products on the market as component parts;

8. Meet the safety laws and regulations of the country or region where the fixture is used;

9. The design plan follows the priority principle of manual, pneumatic, hydraulic, and servo in order;

10. Form the serialization and standardization of the company's internal products.

The special fixture with good economy should adopt standard components and standard structure as much as possible, and strive to be simple in structure and easy to manufacture to reduce the manufacturing cost of the fixture. During the design, the necessary technical and economic analysis of the fixture plan should be carried out according to the order and production capacity to improve the economic efficiency of the fixture in the production.
