Horizontal Machining Center

Abstract

The invention provides a horizontal machining center. The horizontal machining center comprises a base, a main shaft head assembly and a stand column assembly. The stand column assembly is arranged on one side of the upper portion of the base. The stand column assembly is connected with the base in a sliding manner. The end, far away from the stand column assembly, of the upper portion of the base is provided with a workbench. The arrangement direction of the workbench is the same as the sliding direction of the stand column assembly. The main shaft head assembly is arranged on one side of the stand column assembly. The main shaft head assembly faces the workbench and is perpendicular to the X direction end face of the workbench. The main shaft head assembly is connected to the stand column assembly in a sliding manner. The main shaft head assembly comprises a main shaft box and a main shaft. The main shaft box is connected with the main shaft in the Z axis direction in a sliding manner. The main shaft can move in the X direction, the Y direction and the Z direction; and the workbench and the base are integrated, rigidity is good, a rotating table is arranged on the workbench, a large and heavy part can be completely machined though one time of clamping, and precision is high.

Description

technical field [0001] The invention belongs to the field of numerical control equipment, in particular to a horizontal machining center. Background technique [0002] Horizontal machining centers are mainly used to process large parts, such as box parts or parts with deep holes. Such parts are widely used in aerospace, aviation, oil exploration, heavy industry machinery, etc., so the horizontal machining center There are also high requirements for precision. The horizontal centers in the market are mainly divided into fixed column type and fixed column type. These two structures mostly use the spindle box and column to move, and cooperate with the workbench to realize the machine tool. X, Y, Z axis three Displacement changes in three directions. Among them, the spindle ram feed type and the shaft table are fixed, but it is suitable for processing small and medium-sized multiple parts. For long and large heavy shaft parts such as oil probe rods, it is troublesome to clamp an...

[0002] Horizontal machining centers are mainly used to process large parts, such as box parts or parts with deep holes. Such parts are widely used in aerospace, aviation, oil exploration, heavy industry machinery, etc., so the horizontal machining center There are also high requirements for precision. The horizontal centers in the market are mainly divided into fixed column type and fixed column type. These two structures mostly use the spindle box and column to move, and cooperate with the workbench to realize the machine tool. X, Y, Z axis three Displacement changes in three directions. Among them, the spindle ram feed type and the shaft table are fixed, but it is suitable for processing small and medium-sized multiple parts. For long and large heavy shaft parts such as oil probe rods, it is troublesome to clamp and position. Moreover, it must consume a large amount of power, and the repeat positioning accuracy is poor, which affects the processing accuracy, which in turn affects the processing quality of the parts, affects the product qualification rate, and increases the processing cost. To solve the above problems, it is necessary to provide a stable and high-precision Horizontal Machining Center
