JPS60104624A - Tool length correcting clutch plate and tool length correction device in tool holder - Google Patents

Abstract

PURPOSE:To correct the tool length without removing a tool by bringing into contact and coupling rough surfaces of a stuck clutch plate with the end surface of an adjustment screw screwing into a thread hole coaxial with the tool fitting hole of a holder proper and the end surface of the shank section of the tool respectively. CONSTITUTION:One face of a circular, then base 31 with a uniform thickness is formed in rough surfaces 32 to constitute a clutch plate 30, which is stuck so that the rough surfaces 32 are brought into contact with the end surface of the shank section 20 of a tool and the end surface of an adjustment screw 23 respectively. When correcting the tool length, the shank section 3 is extracted from the cylinder of a machine tool, the driving gear 14 of a holder 1 is rotated, and the tightening of the shank section 20 of the tool by a taper collect 5 is loosened via the engagement of bevel gears 16, 12. When the relative rotation is applied to the holder proper 1, the adjustment screw 23 is driven to rotate via the coupling of the tool 20 and adjustment screw 23 with the rough surfaces 32, 32 of the clutch plate, thus the tool length can be corrected without removing the tool from a fitting hole 2.

FC is the center of the holder body 1, and a block-like driven gear 9 that freely rotates around the center of the holder body 1 is supported by a V-shaped snap ring 10 so that it does not move toward the VC. A bevel gear 12 is engraved on one end surface vc of the VCσ thread 11 in the axial direction of the housing.

On the other hand, in a recess 16 formed on the side of the holder body 1, a drive gear 14 is supported by a snap ring 15 so as to be rotatable about an axis perpendicular to the central axis of the holder body 1. 1mIJHα driven gear 9 umbrella washing wheel 12
A bevel gear 16 meshing with Vt is provided to rotate the drive gear 14, and when closed, the driven gear 9 rotates around the center of the holder body 1 at a reduced speed.

The meshing of these minute protrusions between the 11 parts 62 and the VC tension can eliminate the loss of torque transmitted from the tool to the adjustment screw 26.

(f) Effects of the Invention The clutch plate of the present invention has a sound pressure plate of uniform thickness on all the substrates, and the rough surface of the friction plate is large! A
After forming the entire surface, apply adhesive to the other surfaces until the contact force VC between the metal and the metal is superior, and then apply the WIN In of the tool holding device's adjustable cliff Shizuko 2X and the 7fL of the shank part of the straight shank tool.
Since the VC charmer should be able to use something, it is necessary to use all general-purpose equipment. Please be careful with machining straight shank tools.

That is, the tool holding device VCS, which has all the leg adjustment levers, is then attached to the straight shank tool so that its shank end L [I is brought into contact with the end face of the adjustment lever).

Since the foot is measured by contacting the end face of the ra strain, the end face of the adjusting screw and the end face of the shank of the straight shank tool are formed in an extended plane with respect to the central axis of the straight shank tool, and the end face of the straight shank tool is Both the IB curve and the curvature of the road surface are well formed by 4 degrees. Although a tool holding device VC for attaching a general-purpose tool is formed with a groove that engages with the drive shaft, the Cl7J position also does not prevent the clutch plates of the present invention from coming into contact with each other.

Therefore, take a general-purpose tool (1) tool holding device, the end of the adjusting screw @ 2, and store the clutch grating of the present invention at the shank end 11 (I) of a general-purpose straight shank tool. It is necessary to remove the Shun Vt worker who loosened the Taber collet due to the length correction VL from the tool holding device (,7--Hakoretsu) td9 VCLL! J movement is now for tool length correction sound? +U is used to make the tool length correction operation easier for general-purpose tool hokari 1 and 2 machining and general-purpose straight shank tool kit 2, and to make the tool length correction operation easier.
It is possible to shorten the time spent in C and O.

Since it forms the -IfIJII'cσmagishi's large coarse part of the clutch plate, the torque transmission between the clutch plates is smooth and the force VCC applied to the straight shank tool is reduced. You can easily turn the tuning bell.

The rough part of the upper B is formed by forming a protrusion by aligning a large number of minute protrusions vertically and radially in a curve on the board, and the rough part between the clutch plates. The engagement is due to the engagement of the front B pi micro-tipped spoon with VC, and both sets ■
It is possible to correct the tool amount at a positive tVC without incurring loss of torque transmitted to the control force.

In addition, this tool has a long-sleeved formal wear @VS, and a VC tool mounting hole is formed concentric with the center axis of the holder. The straight shank tool is formed to face inward, and the hemp thread hole 1/(-) is formed coaxially with the front a plastic tool attachment hole to hold the entire straight shank tool (a>H), and the shank part of the straight shank tool is One end surface of the y-coupler is brought into contact with the end (5), and the metering screw is inserted into the holder main body VC.
By rotating the tool relative to the VC, set the tool length to h1j.
If it is a VC-type tool holding device that needs to be corrected, any money-type tool holding device may be used.

One side of the VC surface of the manufactured word, the I61 scouring coefficient according to the I61 roughness coefficient, and the entire clutch plate formed with a welding agent, and the VC dust between the edges of the shank of the straight shank tool. The rough round part formed on the clutch plate was deposited on the front 91 leg M screw. When correcting the tool length of the tool holding device V
C, fix the VC on the length measuring device (tool setter) while holding the tool in the tool holding device section, loosen the holding of the tool, and then hold the straight shank tool and press it in the direction of the cap. Since the adjustment screw can be rotated against the tool holding device through the engagement of the 8i111f1 part formed with the latch grating VC in the front side, the straight shank is completely straight shank. It is possible to correct the tool length without cutting 14y or 9 out of the way from the special scale straightness. It is possible to correct the tool length extremely easily by simply coating the 5Iiii surface of the shank with a layer of VCC.
