Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of screw adjustment and leveling, in particular to a screw adjustment and leveling device for a press machine. Background Art
[0002] For a lead screw, its straightness must meet certain requirements in order to work properly. Therefore, during the lead screw production process, the lead screw whose straightness does not meet the requirements needs to be straightened. Generally, the lead screw is straightened by using a lever dial indicator to detect the deviation in a certain section, and then it is straightened by a press.
[0003] When the existing lead screw is adjusted and leveled on a press, if the deviation is too large, the pressure will be increased to press the lead screw downward. At this time, the lead screw is subjected to greater force and is more bent. When the pressing is finished, the bent lead screw will rebound greatly. Due to the effect of toughness, the lead screw will be separated from the placement position and fall onto the workbench or the ground, causing damage to the lead screw surface and causing it to be scrapped. Therefore, we proposed a press lead screw adjustment and leveling device. Utility Model Content
