Problems solved by technology
Especially for tubes and sleeves with relatively thin wall thickness, the roundness and cylindricity of the workpiece are technically required. The disadvantage is that the clamping force causes product deformation, and the roundness and cylindricity of the bored hole are difficult to control and the accuracy is difficult to guarantee.

The invention relates to a fully-automatic workpiece pressing device, comprising a body. The front end of the body is internally provided with a workpiece hollow cavity; the body at the outer side of the workpiece hollow cavity is slidingly provided with a pull rod along the axial direction, the external end of the pull rod is provided with a pressing block protruding toward the direction of the workpiece hollow cavity, and the internal end of the pull rod can be fixed on a push and pull disc through a fixed pin in a rotation mode; the center of the push and pull disc is fixedly connected with a pull rod of a main shaft, and the pull rod of the main shaft is in transmission connection with a power source; the pull rod is cylindrical, and is provided with a helical ring groove on the external surface; and the body is provided with a positioning pin which is in matching arrangement with the helical ring groove of the external surface of the pull rod. The fully-automatic workpiece pressing device adopts the excircle orientation and an end surface pressing mechanism so as to solve the problems of deformation, roundness, cylindricity oversize and the like of workpieces machined and improve the production efficiency. The invention has simple operation and convenient maintenance, reduces the production cost and guarantees the product quality.
Description
technical field [0001] The invention relates to a numerically controlled lathe or a pressing device for the lathe, in particular to a fully automatic workpiece pressing device which automatically presses and loosens the end face of the workpiece. Background technique [0002] At present, three-jaw chucks or other forms of fixed outer circles are used to process the inner holes of workpieces. Especially for tubes and sleeves with relatively thin wall thickness, the roundness and cylindricity of the workpiece are technically required. The disadvantage is that the clamping force causes product deformation, and the roundness and cylindricity of the bored hole are difficult to control and the accuracy is difficult to guarantee. . Contents of the invention [0003] The purpose of the present invention is to provide a fully automatic workpiece pressing device, which can improve production efficiency and ensure product quality. [0004] In order to achieve the above object, t...
