Fixture is a kind of special equipment or tool, which is used to clamp or position the workpiece in machining to meet certain technological requirements.

Design principle of fixture

1. Fixing products and tools with fixtures

Fix products and tools with vises and clamps. , in order to free up hands for two-handed operation.

Use special tools

The tooling used in the production line should be the most suitable for the product, and it is a special manual tool to improve the production efficiency.

3. Combine the two kinds of tooling into one.

Reduce the trouble of changing tools, thus reducing the man-hour consumption of turning and pulling and improving the work efficiency. Common red and blue wool and pencils with erasers in life.

4. Improve the convenience of tool design and reduce fatigue.

(1) The tool handle is easy to grasp.

(2) Work tools should be coordinated with human movement.

⑶ The operation of fixture should be evaluated by IE method.

5. The mechanical operation is relatively stable and the operation is streamlined.

(1) The operating position should be close to the concentration.

⑵ Let the machine minimize or get rid of human monitoring and assistance.

(3) Switch position and next working procedure.

(4) the workpiece automatically falls off

5] Automation capable of self-inspection.

[6] Safety first.

Once miniaturized

It is easy to prepare homework.
