Technical field

[0001 This utility model relates to an auxiliary processing device for parts, especially an auxiliary processing device for thin-walled ring-shaped cast aluminum parts. Background technology in the field of parts processing

[O0Q] In the machining of mechanical parts, we often encounter the machining of some Pubi annular cast aluminum parts, and its manufacturing accuracy is difficult to meet the design requirements. The reason is that this part (see Figure 1 and Figure 2) has high machining accuracy (3 sets of holes with an included angle of 120° and a size of Φ3mm with tolerance of H7, and the shaft position with an outer diameter of 27.8m and tolerance of h7 is 0.03mm: The distance from the center of the hole Φ3m to the bottom of the groove is 3.1m±0.02m), the structural rigidity is poor, and the distance between a group of holes of the part is small, and the measurement is more difficult. Due to the high precision requirements of the parts and the influence of the internal quality of the casting (such as internal pores, blisters, impurities, etc.), the hole is prone to drift during hole processing. In order to prevent the generation of scraps, the size of the parts must be monitored at any time. For a long time, due to the limitation of the part structure, the method of monitoring can only be carried out with a three-coordinate measuring instrument. However, due to the small holes of the parts and the small distance between the holes in the first group, the probe of the three-coordinate measuring instrument can only measure the orifice, which makes the measurement result and the actual size sometimes have errors, causing misjudgment of the parts: In addition, the number of three-coordinate measuring instruments is limited, and it is not possible to monitor each part in real time. When the parts are added τ, the parts are out of tolerance due to tool wear, machine zero drift, and the influence of the internal quality of the casting. How to prove the machining accuracy of the parts, reduce the out-of-tolerance scrap, and realize the real-time monitoring of the parts is the current problem.
