Description

Positioning device for deburring inner wall of cylinder Technical Field The utility model relates to the field of machining equipment, in particular to a positioning device for deburring the inner wall of an air cylinder. Background The cylinder is used as a key component in a mechanical system, and the accuracy of the internal structure directly influences the performance and service life of the whole system. The core of the cylinder is a central shaft which is typically perforated with a plurality of holes, the size and location of which are determined by specific design requirements. The presence of these holes enables the cylinder to perform the functions of fluid control, pressure regulation, etc., and therefore the quality of the hole processing is critical. Punching is a critical step in the shaft manufacturing process. Since the punching is performed from outside to inside, burrs remain on the inner wall of the hole. These burrs can affect not only the quality of the fit of the shaft with other components, but also the non-uniformity of fluid flow, which in turn affects the performance of the cylinder. To remove these burrs, sanding or other post-processing steps are typically required. For larger holes, burr removal is relatively easy because the larger hole space is easier for the handling tool to access and process. However, for smaller holes, burr removal is more difficult because of the limited space of the small holes and the difficulty of efficient operation of conventional mechanical grinding methods. At present, an electrolytic flushing method is generally adopted in the industry to remove burrs in small holes, and the burrs are gradually melted and removed under the action of electrolyte. However, the existing deburring process has some obvious disadvantages. First, to ensure alignment of the small holes with the electrolytic rinse site, positioning is typically required with the large holes as a reference. This procedure requires manual rotation of the central axis of the cylinder to ensure that each orifice is accurately aligned with the flushing position. The manual operation is not only inefficient, but also it is difficult to ensure accuracy of each alignment, resulting in unstable processing quality. In addition, manual operation also easily introduces human error, further influences the effect of burring.
