Manual press

Abstract

The invention relates to a manual press machine. The manual press machine comprises a machine seat (1), an installation barrel (2) is arranged on the machine seat (1), an ejector column (4) is arranged in the installation barrel (2), the lower end of the ejector column (4) is provided with a press head (8), the top of the installation barrel (2) is provided with a square-tooth screw (5), the lower end of the square-tooth screw (5) is connected with the ejector column (4), and the upper end of the square-tooth screw (5) is provided with a hand wheel (13); an annular limit groove (23) is formed in the outer side of the ejector column (4), the left side and the right side of the installation barrel (2) are provided with a first nut (7) and a first bolt (6) respectively, and the front end of the first bolt (6) extends into the annular limit groove (23) in the outer side of the ejector column (4). According to the manual press machine, the requirements of straightening and interference fit assembly of shaft parts in a plant can be met, the production efficiency is greatly improved, and the final product quality is guaranteed.

Description

technical field [0001] The invention relates to a manual press and belongs to the technical field of machining equipment. Background technique [0002] At present, during machining in the factory, it is often necessary to straighten some shaft parts, or to assemble some parts with interference fit. The traditional operation method of these tasks is usually done manually by workers, and most of them need to cooperate with some machines in the factory. The operation not only occupies the machine table and affects the progress of other operations, but also is very inconvenient for workers to operate, greatly reducing production efficiency, and the final alignment and assembly effects are not ideal. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages and provide a manual press, which can meet the requirements of alignment and interference fit assembly of shaft parts in the factory, greatly improve production efficiency...
