Design Points of CNC Machining Clamping Fixture

1. The above picture is a reference drawing of the gas test tooling. The specific structure needs to be designed according to the actual structure of the product. The idea is to seal the product in the simplest possible way, and fill the part to be tested and sealed with gas to confirm its tightness; 　　2 The size of the cylinder can be adjusted according to the actual size of the product, and it is also necessary to consider whether the stroke of the cylinder can meet the convenience of picking and placing the product; 　　3, the sealing surface in contact with the product is generally made of Uli glue, and the NBR rubber ring has good compression. At the same time, please note that if there are positioning blocks in contact with the appearance of the product, try to use white plastic plastic blocks and cover them with cotton cloth to prevent damage to the appearance of the product; 　　4. The positioning direction of the product should be considered when designing to prevent The internal leakage of gas is trapped inside the product cavity and false detection occurs.
