Large-scale horizontal type machining center

Abstract

The invention provides a large-scale horizontal type machining center and belongs to the technical field of machine tool equipment. The large-scale horizontal type machining center comprises a workbench translation device and a main shaft device, a workbench of the workbench translation device can realize translation in the X-direction and the Y-direction, a Z-direction support seat of the main shaft device can be slidably arranged on a Z-direction rail, a Z-direction screw rod is in threaded connection with a Z-direction screw rod nut, a pushing screw rod is in threaded connection with a pushing screw rod nut, one end of a winding connector is installed on a pushing support seat, the other end of the winding connector is clamped into a winding clamping groove at the right end of a main shaft, a second gear is installed on the main shaft through a flat key, the second gear and the flat key can slide relatively in the Y-direction, first support rolling balls and a first annular rail canbe connected in a rolling manner, second support rolling balls and a second annular rail can be connected in a rolling manner, and a first gear is engaged with the second gear. According to the large-scale horizontal type machining center, the main shaft can stretch out in the Y-direction, drilling and milling machining is realized, and the machining precision of workpieces is greatly improved.

Description

technical field [0001] The invention relates to the technical field of machine tools, in particular to a large horizontal machining center. Background technique [0002] A machine tool refers to a machine that manufactures a machine, also known as a machine tool or a tool machine, and is customarily referred to as a machine tool. Generally divided into metal cutting machine tools, forging machine tools and woodworking machine tools. There are many ways to process mechanical parts in modern machinery manufacturing: in addition to cutting, there are also casting, forging, welding, stamping, extrusion, etc. The final machining is done by cutting on the machine tool. Machine tools play an important role in the modernization of the national economy. CNC milling machine is an automatic processing equipment developed on the basis of general milling machine. The processing technology of the two is basically the same, and the structure is somewhat similar. CNC milling machines ar...

Problems solved by technology

However, due to the large structure of large horizontal machining centers, the accuracy is poor. Especially in drilling, milling and other processing, the workpiece is installed on the workbench. After positioning at the specified position, common large horizontal machining centers rely on the workbench Y Direction of movement to achieve drilling or milling, but such a structure will seriously affect the machining accuracy of the workpiece

If there is a large-scale horizontal machining center on the market that does not move the worktable after the workpiece is positioned, if the spindle can extend along the Y direction, the quality of drilling and milling will be greatly improved, but there is no such large-scale horizontal machining center on the market
