Description

Technical Field

[0001] The utility model relates to the technical field of vertical lathe processing, in particular to a workpiece clamping and adjusting mechanism of a vertical lathe. Background Art

[0002] The biggest difference between a vertical lathe and an ordinary lathe is that the spindle of a vertical lathe is vertical, which is equivalent to standing an ordinary lathe upright. Since its support seat is in a horizontal position, it is more suitable for processing large and heavy workpieces with a diameter of 1.5 and a short length and complex shapes, such as cylindrical surfaces, end faces, conical surfaces, cylindrical holes, conical holes, etc. of various disks, wheels and sleeves. At the same time, since its support seat is horizontal, it is more convenient to clamp the workpiece. However, there are still many problems with the fixtures used in the production process of the current vertical lathe. In view of the problem that during the use of the current vertical lathe, due to the imperfect clamping of its fixture, the support seat is easy to cause the workpiece to escape from the clamping of the fixture when it rotates, thereby increasing the difficulty of lathe processing. In view of this, we propose a workpiece clamping and adjustment mechanism for a vertical lathe. Utility Model Content
