Abstract

PURPOSE:To adjust a machining diameter automatically with a tool left fitted by coupling an adjusting shaft protruded at the tip of a tool main body with an adjusting member fixed to the main body by means of the numerical control of a main shaft before the main shaft is rotated. CONSTITUTION:A dovetail groove 6 is formed on the cutter bed 4 of a tool main body 1, and sliding beds 8, 8a for fitting a cutter 7 are slidably coupled with the groove 6. A portal bracket 11 fixed to the cutter bed 4 is rotatably supported by right and left feed threads 12, 13 screwed into the sliding beds 8, 8a. In order to operate the threads 12, 13 simultaneously, a gear 18 simultaneously engaged with bevel gears 14, 15 is fitted to an adjusting shaft 19 supported by the bracket 11 and provided protrusively at the tip of the main body 1. In order to rotate the operation section 20 of the shaft 19 automatically, an adjusting member 23 formed with a rectangular hole 22 to be engaged with the operation section 20 is fixed at an optional position of a machine tool 21 facing the tool main body 1.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention (a) relates to a tool diameter adjustment method in which the machining diameter of a tool is fully automatically adjusted.

NC (Number 1 direct poison IJ#) IF' boring machine f A boring tool used for machining with a counter etc. has a sliding tool at the tip of the tool body that can be positioned in a radial direction of 1C. A table is provided, and a cutting tool is attached to this sliding table, and the machining diameter is manually adjusted using an adjustment gauge or the like before machining.

For this reason, when there is a large machining allowance in VC such as boring rough machining,
Adjust the machining diameter of the tool several times, or prepare several tools with different machining diameters. When machining various types of upper grooves, it is necessary to adjust the machining diameter in advance according to the dimensions such as rc4cn, and to use a large number of tools.
It has the disadvantage that it requires a lot of time and money to handle and manage the tools.Also, in order to adjust the machining diameter, the VCA must be removed from the raw @ after the machine tool has completely stopped, which reduces the idle time of the machine tool. In addition to this, continuous unmanned operation is impossible for machine tools that do not have a tool changer, and the number of tools required to change tools automatically increases. 0 misexplosion 8A is a structural frame of the present invention which solves the drawbacks of the conventional method and which aims to provide a tool diameter adjustment method that can automatically adjust the machining diameter with the tool attached. The machining diameter adjuster 1l is attached to the tip of the tool body, which is attached to the main spindle and the cutter is attached via the machining diameter adjuster.
While protruding an operating adjustment @, an adjustment member t that can be engaged with the adjustment shaft is fixed on the machine tool body, and the adjustment shaft 'fr is engaged with the adjustment member by numerical position control of the main shaft. The main shaft is then rotated by a predetermined amount.

Hereinafter, the method of the present invention will be specifically explained with reference to all the drawings.

A shank part 2 is formed on the eyebrow part of the tool, which is connected to three shelves of an NC (numerical control) machine tool (not shown).
1 A base body 32 and a disc-shaped tool rest 4 are integrally fixed in a lotus joint at the tip. 0 This tool rest 4 vc is a machining diameter adjustment a.
A radial VC dovetail flange 6 is formed as the structure 5, and the n-circle end is opened around the tool post 4, and a sliding base 8, 8a for attaching the cutter 7 to the dovetail flange 6 is located at its lower end. It is attached through the dovetail 9 and is slidable.

Then, the blade 7 is tightened to this sliding table 8.8a with a set screw 10, and in order to adjust the machining diameter by this blade 7, a gate-shaped bracket 11 is fixed to the center of the blade 4. A right-hand feed screw 1 with an equal hitch P and a stone screw or a left-hand screw is formed on both sides of the bracket 11.
2 and pressure feeding 5 The base end of the screw 13 is supported in a manner that can be transmitted orally, and a bevel gear 14 and 15 with the same number of bacteria is attached to the Nrf.
It is. - 10,000, the tips of the stone feed 9 screw 12 and the pressure feed 9 screw 13 are screwed into female screws 16 and 17, which are either right-handed or left-handed, formed on the sliding bases 8, 8a. In order to operate the left and right feed screws 12 and 13 at the same time, a bevel gear 18 that meshes with the bevel gear 14 and 15 at the base end of each is supported by the tool body l.
It is provided protruding from the tip and is attached to the fc adjustment shaft 19. The distal end a of this adjustment shaft 19 has a rigid side surface and a square cross section formed by the operation s20.

Therefore, by rotating the operating section 20, the bevel gear 14
and 15″It through the right feed screw 122 and pressure feed 97
Turn the second screw 13 and screw it into place with this feed screw 12.13.
Adjust the machining diameter D' of the cutter 7 by riding the tfc sliding table 8.
An angler 22 that engages with the operating part 2oζ of the adjustment distortion @19 is formed at an arbitrary position between the tool body 1 and the tool body 1 of the main bowl body.
'c The tensioning member 23 is fixedly installed. Adjustment of the machining diameter of the tool in the assembly.
In this state, the diameter of the sword is iD. After completing the predetermined upper 9 machining with this machining diameter, move the king @ to ff1ic to the point where it is opposed to the adjustment member 23 by controlling Cf51J, and then slide the king @ to the adjustment 11119 base end. The operating part 20ta14 is inserted into the strain member 230 square hole 22 and held at τ.

Thereafter, it is necessary to rotate the adjustment shaft 19 in order to obtain the desired machining diameter d, but according to the method of the present invention, the adjustment shaft 19 is rotated relative to the rotation of the main shaft.

In the case of C, the tool non-operating 10 rotation time T (min) required to make the machining diameter t-Dρ=d Rotation ffkN (Ypm), 5.v>glIil car 14
If ゜15 and ρ1δ - 箪18ζ correspond with l:l, then n is given by the following equation.

Therefore, this rotation time T is controlled by INcNC in advance.
By inputting the VCC quaru time and rotating the main @, the machining diameter 'id&? : Adjustment distortion 〇 Also, when using NC control, the machining diameter di can be changed by changing the rotation time T6C and the rotation speed N
You may also adjust the machining diameter by adjusting the VC, μ, and the cutting diameter! !
It is desirable to always take into consideration the rake and the bankrasonyu in the ρ1 bevel gear 14*15.18y of cam5, and adjust it only in the direction of increasing the machining diameter. case 1 caa small case a
Adjust by reducing the diameter to the required size and then expanding it.

In addition, by installing a bank crash removal device, these shadows 41J [! J may be excluded.

After adjusting the machining diameter in this way, adjust the adjustment member 23)L
:) Pull out the adjusting shaft 19, return the cutter 7 to the processing position, and restart the engine. ◎In addition, in the example above, all 21 cutlers were fixed, but if only 1 cutter is attached. -? Similarly, in the case of three or more pieces, the diameter of one sword can be adjusted automatically. There is no need to prepare a large number of tools for each operation, making tool management easier and reducing costs.

In addition, since the tool body can be adjusted to the machining diameter t with the NC machining type VC attached, adjustment i/(required work time can be shortened and automation can also be achieved. Therefore, continuous black operation is possible.
