Description

Technical Field

[0001] The utility model relates to the technical field of processing a marine cylinder sleeve, in particular to a screw rod roller bracket used for processing a marine cylinder sleeve. Background Art

[0002] There are many holes on the outer circle of the marine cylinder liner, which is generally processed on a boring machine. The traditional calibration method is to place a pair of rollers at both ends of the cylinder liner, calculate the roller spacing according to the outer circle size of the cylinder liner, and then drill holes to fix the roller position. This operation has the following disadvantages: 1. The same base plate can only fix a small number of cylinder liners of several models and cannot cover the production of multiple models; 2. During calibration, it is necessary to draw and calculate according to the actual situation, which increases the process preparation time; 3. Each time a different cylinder liner is processed, the roller needs to be disassembled and repositioned and installed, which consumes time; 4. Fine-tuning can only be performed by knocking with copper rods and gaskets, which is difficult to operate.

[0003] Therefore, it is necessary to provide a new screw roller bracket for processing marine cylinder sleeves and a use method thereof to solve the above-mentioned technical problems. Utility Model Content
