Four axis deep hole drilling machine

Abstract

The invention provides a four-spindle deep-hole drilling machine and belongs to the technical field of tools. The four-spindle deep-hole drilling machine solves the problems of expensive equipment, high machining costs, the low machining efficiency and the like due to the fact that multi-hole and multi-direction drilling of workpieces is difficult to complete once on ordinary tools and multiple times of clamping and machining is required. The four-spindle deep-hole drilling machine comprises a machine body, a clamp is arranged in the middle of the machine body, transverse guide rails are arranged on two sides of the clamp respectively, transverse sliding tables capable of sliding along the transverse guide rails are arranged on the transverse guide rails respectively, and workpiece drilling mechanisms are arranged on the two transverse sliding tables respectively. A plurality of straight long drills are arranged on each transverse sliding table and driven synchronously through motors on the transverse sliding tables. Compared with 30 minutes required for machining of a vehicle gear box product, only 5 to 7 minutes are required by the four-spindle deep-hole drilling machine, the production time is greatly saved, and the four-spindle deep-hole drilling machine has the advantages of being capable of reducing the production time greatly, suitable for large batch production and the like.

Description

technical field [0001] The invention belongs to the technical field of machine tools, in particular to a four-axis deep hole drilling machine. Background technique [0002] The porous and multi-directional drilling of the workpiece is difficult to complete on a general drilling machine at one time, requiring multiple clamping processes, or using CNC machining centers for processing, expensive equipment, high processing costs, and low processing efficiency. [0003] At present, the Chinese patent literature discloses a four-axis drilling machine authorization announcement number: CN201880947U, which includes a frame and a spindle box arranged on the frame. A drill bit that can move up and down is installed on the spindle box. The drilling machine also includes a The workpiece is sent to the feeding device under the drill bit. The feeding device is set on the frame. It is characterized in that: the spindle box is equipped with two sets of left and right drill bits that can be ...

AI Technical Summary

Problems solved by technology

The above-mentioned structure utilizes the headstock to drive four drill bits, and simultaneously drills four workpieces, but the drilling of multiple holes in a single workpiece cannot be realized. According to the principle of the above-mentioned structure, the position of the drill bit can also be adjusted and the fixture of the workpiece to perform multi-hole machining of a single workpiece, but the overall structure of the equipment is still too complicated, the stability during the drilling process is not good, and the required production cost is extremely high
