A horizontal multi-axis woodworking deep hole drilling machine

Abstract

The invention discloses a horizontal multi-shaft woodworking deep hole drilling machine which comprises a machine body and an electric-control device. The machine body is provided with at least one set of deep hole drilling device. Each set of deep hole drilling device comprises a spindle seat and a terminal disc; a central chuck is arranged between the spindle seat and the terminal disc; a drill spindle is installed on the spindle seat; the drill spindle is driven by a spindle motor to rotate; a through hole suitable for the drill spindle to penetrate through is formed in the central chuck; the outer end face, close to one side of the terminal disc, of the through hole is matched with one end of a workpiece in a positioned mode; the other end of the workpiece abuts against the center of the terminal disc; a spindle core is fixed in the spindle seat; a through spindle core hole is formed in the spindle core; a chuck is installed in the spindle core hole; the chuck tightly clamps the drill spindle through a nut; and the spindle core hole extends axially towards the inner side to form a spindle core extension hole which is suitable for containing the drill spindle. According to the horizontal multi-shaft woodworking deep hole drilling machine, the structure is simple and reasonable, and the stability during drilling of the drill spindle can be improved; and in addition, by lengthening the drill spindle, the drill spindle can continue to be used through simple adjustment after one end of the drill spindle is abraded.

Description

technical field [0001] The invention relates to a woodworking drilling machine, in particular to a horizontal multi-axis woodworking deep hole drilling machine. Background technique [0002] At present, due to the unreasonable design of the existing woodworking deep hole drilling machines, the depth of the drilling holes has a bottom limit, and deeper holes cannot be drilled, and because the drilling shaft 1 required for drilling deep holes is longer, if the machine design is not enough reasonable, such as figure 1 As shown, there are the following defects: [0003] 1) The chuck 3 of the main shaft seat 2 clamps the end of the drill shaft 1, while the other part of the drill shaft 1 protrudes from the main shaft seat 2, causing the protruding part to sag easily, and the drill shaft 1 tends to shake greatly during drilling , the concentricity of the deep hole after processing is low, the processing accuracy is low, and the reject rate is high; [0004] 2) In addition, sinc...

Problems solved by technology

[0002] At present, due to the unreasonable design of the existing woodworking deep hole drilling machines, the depth of the drilling holes has a bottom limit, and deeper holes cannot be drilled, and because the drilling shaft 1 required for drilling deep holes is longer, if the machine design is not enough reasonable, such as figure 1 As shown, there are the following defects:

[0003] 1) The chuck 3 of the main shaft seat 2 clamps the end of the drill shaft 1, while the other part of the drill shaft 1 protrudes from the main shaft seat 2, causing the protruding part to sag easily, and the drill shaft 1 tends to shake greatly during drilling , the concentricity of the deep hole after processing is low, the processing accuracy is low, and the reject rate is high;

[0004] 2) In addition, since the chuck 3 of the main shaft seat 2 holds the end of the drill shaft 1, when the drilling section of the drill shaft 1 is partially lost during drilling, the entire drill shaft needs to be replaced, resulting in extreme big waste
