Horizontal-type five-axis machining center

Abstract

The invention discloses a horizontal-type five-axis machining center. The horizontal-type five-axis machining center comprises a machine seat, a cradle supporting seat which is arranged on the machineseat and a cradle body which is installed on the cradle supporting seat. A servo motor is disposed on the cradle supporting seat; the servo motor is in driving connection with a cradle; the servo motor drives the cradle body to rotate in the left-right direction; an x-axis sliding mechanism is disposed on the machine seat; a first machine frame is disposed on the x-axis sliding mechanism; the first machine frame moves leftwards and rightwards on the x-axis sliding mechanism; a y-axis sliding mechanism is disposed on the first machine frame; a second machine frame is disposed on the y-axis sliding mechanism; the y-axis sliding mechanism drives the second machine frame to move up and down; a z-axis sliding mechanism is disposed on the second machine frame; a cutter is disposed on the z-axissliding mechanism; the z-axis sliding mechanism drives the cutter to move front and back; and the movement trajectory of the cutter forms a machining space, and the cradle body is disposed in the machining space. The horizontal-type five-axis machining center provided by the invention is high in accuracy.

Description

technical field [0001] The invention relates to the field of machine tool processing equipment, in particular to a horizontal five-axis machining center. Background technique [0002] With the continuous development of society and the continuous advancement of the scientific level, people have higher and higher requirements for the precision that can be achieved by processing. At the same time, people also require higher and higher requirements for processing equipment. On the one hand, the processing accuracy of machine tools On the other hand, the requirements for the space occupied by machine tools are becoming more and more miniaturized. [0003] At present, traditional horizontal five-axis machining centers generally have x-axis, y-axis, and z-axis so that the relative movement between the workpiece and the tool in the spatial Cartesian coordinate system can be realized, such as the reference document 1 with the publication number CN206825066U. [0004] This reference ...

Problems solved by technology

In the z-axis direction of the comparison file 1, when the guide rail of the z-axis drives the worktable to move along the z-axis direction to the tool for processing, when the tool contacts the workpiece for processing, the worktable can move along the z-axis direction, so the comparison The track of the z-axis, when the tool is processing the workpiece, the worktable has a moment around the contact point between the worktable and the z-axis relative to the z-axis, but since the worktable and the z-axis guide rail are slidingly connected, the worktable There must be a certain gap in the direction of motion, and the rotation of the tool will inevitably generate vibration, which will reduce the machining accuracy

At the same time, the debris generated during processing in Reference 1 can easily enter the track of the z-axis. Once the debris generated during processing enters the track, it will further affect the machining accuracy
