Problems solved by technology

The problem with this technology is that in order to maintain balance, the two adjustment seats and the two boring tool seats need to be kept symmetrical during adjustment. However, in its technical solution, the two adjustment seats need to be adjusted separately, which makes the adjustment process more difficult. inconvenient
[0005] The above-mentioned technology of using a bidirectional screw to simultaneously adjust two tool holders has the following disadvantages: (1) The screw has a thread gap, and when the tool holder is fixed after adjusting the tool holder, the tool holder is easy to retreat, which affects the accuracy of the tool position
[0006] (2) The structure size of the screw rod is long, and it is inconvenient to process and install

Embodiment 1

[0027] Example 1: Combining Figure 1 to Figure 3 As shown, an inner hole boring tool adjustment seat, two tool seats 3 are installed symmetrically at the center of the end face of the tool handle 1, and the outer end of the tool seat 3 fixes the tool 2.

[0028] The side slide bars 1-2 and the middle slide bars 1-3 are symmetrically arranged in pairs. The two middle slide bars 1-3 are on the same straight line passing through the shaft center of the end face of the knife handle 1. The two side slide bars 1-2 are separated on both sides of the middle slide bar 1-3, and the two knife holders 3 are slidably installed between the corresponding side slide bar 1-2 and the middle slide bar 1-3. A dovetail groove sliding connection is selected between the side slide bar 1-2 and the knife seat 3, which can prevent the knife seat 3 from jumping in the axial direction. The knife seat 3 is provided with an elongated hole, and the elongated hole is used to ensure that the knife seat 3 c...

Embodiment 2

[0033] Embodiment two: combine figure 1 , figure 2 and Figure 4 As shown, the difference between the second embodiment and the first embodiment is that the fastening method of the tool holder 3 is different;

[0034]The middle slide bar 1-3 is made up of two oblique blocks 1-4. Set bolt 1-5 is installed in the threaded hole 1-1 on the inclined block 1-4, and set bolt 1-5 is perpendicular to the slope of inclined block 1-4. One side of the knife seat 3 close to the middle sliding bar 1-3 is provided with a sinking groove, and the tapered block 3-2 is embedded in the sinking groove on one side of the knife seat 3 and is fixedly connected by a fastening screw 8 . The tapered block 3-2 is located between the two inclined blocks 1-4, the inner end of the positioning bolt 1-5 faces the tapered block 3-2 and the positioning bolt 1-5 is perpendicular to the slope of the tapered block 3-2.

[0035] Through the two inclined and opposite positioning bolts 1-5, one is convenient to ...

Abstract

The invention discloses an inner hole boring tool adjusting seat, which belongs to the technical field of machining tools. Including the handle, two tool holders are installed on the end surface of the handle; the end surface of the handle has two symmetrical side slide bars and two symmetrical middle slide bars, and the side slide bars and middle slide bars are parallel; the two knife seats are slidably installed on Corresponding between the side sliding bar and the middle sliding bar; the inner end of the tool seat has a rack; the end face of the tool handle is pivotally mounted with a rotating shaft, and a double gear assembly is set on the rotating shaft. The invention cooperates with the double gear assembly in the center to adjust the two knife seats synchronously at the same time, so as to always ensure the central symmetrical state of the knife seat; the double gear structure eliminates the backlash gap of the tooth meshing, and ensures that the knife seat is in the It does not retreat when it is not subjected to a large thrust, which is convenient for controlling the accuracy of the tool holder.

Description

technical field [0001] The invention relates to the technical field of machining tools, in particular to an inner hole boring tool adjusting seat. Background technique [0002] Boring tool is a kind of boring tool and one of the indispensable tools in the field of machining. The most commonly used occasions are inner hole machining, reaming, profiling, etc. There are one or two cutting parts, which are specially used for rough machining, semi-finishing or finishing of existing holes. The double-edged boring tool has two cutting edges involved in cutting at the same time during processing, and the processing efficiency is higher; the radial forces acting on the two symmetrical cutting edges cancel each other out, so that the boring tool body is not easy to generate vibration. [0003] Existing commonly used boring tool adjustment technology, such as a closed adjustment structure of a double-edged adjustable boring tool disclosed by a Chinese patent (CN201455293U), includes a...
