Problems solved by technology

[0003] In some occasions where the position of the top needs to be adjusted frequently, the traditional screw connection method wears out quickly, which will cause the top to not be positioned tightly and move, so the top is not fast enough when positioning the machined parts
In addition, this thread-fitting structure limits the moving speed of the center during adjustment, making it take a long time to adjust the position of the movable center, reducing production efficiency

Abstract

The invention relates to the technical field of mechanical processing, in particular to a top device of a machine tool, which includes a fixed seat, a connecting rod, a block and a cam. The middle part of the connecting rod is fixedly connected, and the other end of the top sleeve is horizontally fixed with a top for pressing against the workpiece. The axis of the top sleeve and the connecting rod are perpendicular to each other, and the lower end of the connecting rod is fixed with a movable rod. Sliding fit, a compression spring is set on the movable rod, one end of the compressed spring is fixed in the spring groove horizontally arranged on the fixed seat, and the other end is fixedly connected with the fixed plate provided on the movable rod; the cam is arranged on the fixed seat and Axial rotation fits between the two, and the cam is provided with an offset that offsets with the set stop pin on the fixed seat, and offsets with the upper end of the connecting rod when the cam rotates. The tipping device of the machine tool adopting the technical solution of the invention can conveniently adjust the progress of the tipping and ensure the accuracy of the tipping.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a machine tool top device. Background technique [0002] At present, in the machining industry, machine tools have become the most frequently used tools in modern machining production. When machining shaft parts, it is also necessary to install a matching top on the machine tool to locate the shaft parts and drive the parts to rotate at a high speed, so that the tool can be easily processed. There are many kinds of shaft parts. When the same machine tool is processing shaft parts of different lengths, it is necessary to adjust the center before positioning the shaft parts. [0003] In some occasions where the position of the top needs to be adjusted frequently, the traditional screw with threaded connection wears quickly, which will cause the top to move without being tightly positioned, so the top is not tight enough to position the machined parts. In addition, the screw-fit...
