Problems solved by technology

[0002] Before the invention of the present invention, due to the large aperture ratio of the deep hole, the slender tool rod, the low rigidity, the vibration is easy to occur, and the boring is deviated to affect the machining accuracy and production efficiency. Therefore, the guiding problem of deep hole machining has always been a problem. problem
When processing large-diameter deep-hole parts on a horizontal lathe, it is often necessary to use a special deep-hole gun drill, or a gun-drilled deep-hole boring tool, which needs to be specially customized, and can only process parts of one diameter specification. It not only increases the cost, but also is not suitable for single piece or small batch production

Embodiment 1

[0029] like figure 1 Shown:

[0030] The present invention is a situation in which the support body 42 and the cutter body 41 are used in combination on the cutter bar 36 . Support body is made of support seat 13, support column 47, spring 45, adjustment ring 15, adjustment nut 17, fastening nut 18. The outer circle 44 of the support column 47 is inserted into the inner ring of the spring 45, and the outer circle 44 of the support column 47 is slidingly fitted with the radial cylindrical hole 48 on the support seat 13; The plane of the inner cavity 49, the other end is against the step of the support column 47, and the support column 47 can be freely expanded and contracted in the radial cylindrical hole 48 of the support seat 13 under the action of the spring 45; the adjustment ring 15 is sleeved on the support seat 13 On the outer circle 9, the inner hole 14 of the adjustment ring 15 is slidably matched with the outer circle 9 of the support seat 13, and the outer cone 12 ...

Embodiment 2

[0040] figure 2 It is another case where the cutter body 41 and the support body 42 are used together, and two cutter body 41 with different sizes and specifications and one support body 42 are used in combination. The cutter body 41 is installed at the left end of the cutter bar 36, and the cutter rod 36 on the left side of the installation body 41 has a space for installing the cooling pipe bolt 20, and the installation method of the cutter body 41 is the same as that of embodiment 1. Thereafter, the support body 42 is installed next to the support body 42, and the installation and debugging method of the support body 42 is the same as the installation and debugging method of embodiment 1; Space for 20 bolts. The installation method is the same as in Example 1

[0041] The inner square tooth thread 3 on the left side of the knife bar 36 is connected with the support plug 54, and its outer cylindrical square tooth thread 56 is tightened with the inner square tooth thread 3...

Abstract

The invention relates to a device for processing a deep hole with large diameter by a horizontal lathe. A supporting body and a cutter assembling body are sleeved in a tool bar; an outer circle of a supporting column is positioned in an inner ring of a spring and is in sliding fit with a cylindrical hole; the spring is arranged on the plane of an inner cavity and between steps of the supporting column; an adjusting ring is arranged on an outer circle of a bearing seat; an inner hole of the adjusting ring and an outer circle of the supporting seat are in sliding fit; a cone body of the outer circle of the adjusting ring and a cone body of the supporting seat are matched; the high position of a round head of a large step is supported against the cone body of the outer circle of the adjusting ring; the cutter assembling body is of a cone shape which is large in the middle part and small at two ends; the cone body is radially distributed at 180 degrees; the right side of the outside of the cutter assembling body is a cylinder; the tool bar is a tubular cylinder; a left inner hole is provided with square thread; a right inner hole is provided with triangular thread; two pairs of key grooves are processed through the axial milling of the outer circle of the tool bar; and axial lines are distributed at 90 degrees on the circumference. The device solves the problems of low rigidity, easy vibration and the like in the deep hole processing and has the characteristics of simple manufacture, flexible and convenient operation, low cost, quick effect, double increase of working efficiency and the like.

Description

technical field [0001] The invention relates to a mechanical processing device, in particular to a processing device for processing large-diameter deep holes with a horizontal lathe. Background technique [0002] Before the invention of the present invention, due to the large aperture ratio of the deep hole, the slender tool rod, the low rigidity, the vibration is easy to occur, and the boring is deviated to affect the machining accuracy and production efficiency. Therefore, the guiding problem of deep hole machining has always been a problem. problem. When processing large-diameter deep-hole parts on a horizontal lathe, it is often necessary to use a special deep-hole gun drill, or a gun-drilled deep-hole boring tool, which needs to be specially made, and can only process parts of one diameter specification. It not only increases the cost, but also is not suitable for single piece or small batch production. Such as machining through hole diameter 60mm- For deep hole p...
