Description

Clamp for processing inner hole of cylinder sleeve and boring machine Technical Field The utility model belongs to the technical field of cylinder sleeve clamps, and particularly relates to a clamp and a boring machine for machining an inner hole of a cylinder sleeve. Background In the traditional cylinder sleeve inner hole processing technology, the lathe chuck is generally used for clamping the outer circle of the cylinder sleeve and processing is carried out in a mode of alternately turning holes at two ends, the working stroke is long, and workpieces are required to be subjected to reversing and clamping adjustment twice, so that obvious cutter receiving marks appear in the inner hole, the form and position tolerance is difficult to meet the high standard requirement, and meanwhile, the labor intensity is also increased. When the existing boring machine clamp is used for machining an inner hole of a cylinder sleeve, indentation is easily caused on the outer wall of the cylinder sleeve, positioning of the cylinder sleeve is inconvenient, and concentricity and straightness of cylinder sleeve machining are not guaranteed. Disclosure of utility model Therefore, the technical problem to be solved by the utility model is to provide the clamp and the boring machine for processing the inner hole of the cylinder sleeve, which can be accurately matched with the size of the cylinder sleeve, ensure the stable installation of the cylinder sleeve, realize no joint mark in the inner hole processing, and obviously improve the concentricity and the straightness of the cylinder sleeve processing. In order to solve the problems, the utility model provides a clamp for processing an inner hole of a cylinder sleeve, which comprises at least two clamping parts. The two adjacent clamping parts are arranged at intervals. Each clamping portion includes a base, a tile cap and a tile. The tile cover is detachably connected to the base, and the tile cover and the base enclose an annular limiting space. The annular limiting space is used for being sleeved on the periphery of the cylinder sleeve. The tile sets up between the inner wall in cylinder liner and annular spacing space.
