Definitions
- the present invention relates to a tool holder suitable for heavy cutting and high-precision cutting in which the gripping force is increased and the gripping area is widened to increase the holding stability and runout accuracy of the tool.
- the tool chuck disclosed in Patent Document 1 reduces the diameter of a chuck cylinder having a tool holding hole and a tapered outer peripheral surface by tightening a nut (clamping cylinder) externally fitted to the chuck cylinder via a needle roller. Holds the tool inserted in the tool holding hole.
- the chuck device disclosed in Patent Document 2 is a hydraulic chuck, and an elastically deformable sleeve is liquid-tightly fitted to a taper inner periphery opened at the tip of the main body.
- An expansion chamber is formed between the peripheral surface and a hydraulic pressure is supplied to the expansion chamber, and the diameter of the sleeve is reduced by the hydraulic pressure to hold the tool inserted into the hole of the sleeve.
- the hydraulic chuck is not suitable for grasping a rough tool with high precision control with a large variation in the shank diameter because the sleeve diameter reduction (tightening margin) is considerably smaller than that of the mechanical chuck.
- the cylindricity of the thin part of the sleeve affects the deflection accuracy of the gripped tool. If the thickness of the thin portion is uneven in each circumferential portion, the amount of diameter reduction of the thin portion varies in each circumferential portion, making it difficult to center the tool at the center of the holder.
- the conventional tool holder has inherent disadvantages in both the mechanical chuck method and the hydraulic chuck method, and can satisfactorily meet the demands to increase both holding stability and tool runout accuracy. It wasn't.
- An object of the present invention is to eliminate the above-mentioned drawbacks seen in conventional tool holders, and to achieve both improvement in stability of tool holding and improvement in tool runout accuracy.
- the present invention is such that a tool holder is provided with two members, a mechanical chuck and a hydraulic chuck, and the two members operate by operating a nut to hold the tool by the two members. I made it.
- the tool holder includes a holder main body provided with a first gripping hole for forming a cylindrical main gripping portion having a first tool holding hole, a tapered tapered outer peripheral surface, and a longitudinal slit, and the gripping tube
- a pressure ring fitted to the outer periphery of the holder so as to be axially slidable, and the pressure ring are connected so as to be relatively rotatable, and are screwed onto the outer periphery of the barrel portion of the holder body formed to have a larger diameter than the gripping cylinder.
- An annular groove is formed on the outer periphery of the nut, a thin wall portion is provided at the groove bottom of the annular groove, and a second tool holding hole having an inner diameter smaller than the inner diameter in the free state of the first tool holding hole is provided at the center. And a sleeve which is inserted into the shaft hole at the center of the holder body at the rear of the gripping cylinder and constitutes a sub gripping portion.
- a pressure chamber formed in the outer periphery of the sleeve by liquid-tightly isolating the annular groove from the shaft hole; a cylinder provided in the body portion with one end opened at a front end of the body portion; A piston partly protruding from the cylinder and inserted so as to be movable in the axial direction, a communication passage communicating the cylinder and the pressure chamber inside the body, and sealed in the cylinder, the communication passage, and the pressure chamber Has hydraulic fluid.
- the nut is propelled in the axial direction while rotating by the rotation operation, and the pressure ring follows, and the pressure ring pushes and moves the piston while reducing the diameter of the gripping cylinder.
- the hydraulic pressure is generated, and the thin portion of the sleeve is reduced in diameter by the hydraulic pressure, and the tool is held by the first tool holding hole and the tool is held by the second tool holding hole at the same time.
- a split collar divided into a plurality of portions in the circumferential direction is fitted on the outer periphery of the thin portion.
- a plurality of cylinders and pistons are arranged at equal circumferential points.
- a tapered hole having a small diameter on the back end side, a tapered sleeve press-fitted into the tapered hole, and an elastic body that urges the tapered sleeve in the press-fitting direction into the tapered hole,
- the outer diameter of the rear part of the sleeve is adapted to the hole diameter of the hole in the center of the taper sleeve, and the rear part is inserted into the hole in the center of the taper sleeve.
- a friction reducing member is interposed between the nut and the body part into which the nut is screwed.
- the friction reducing member may be a conventionally used steel ball or needle roller.
- the tool holder according to the present invention is provided with a mechanical chuck and a hydraulic chuck. Since the tip side is a mechanical chuck that reduces the diameter of the gripping cylinder and holds the tool in the first tool holding hole, the shank of the tool makes extensive surface contact with the hole surface of the first tool holding hole. Further, since the entire area of the gripping cylinder is reduced in diameter, the tightening at the mouth is stably performed.
- the sleeve arranged behind the gripping cylinder constitutes a sub gripping part, and the tool is held by the second tool holding hole provided in the sleeve.
- the gripping area is expanded and the gripping force is further enhanced.
- the sub gripping portion is a hydraulic chuck that operates by hydraulic pressure, and by providing this sub gripping portion, a large distance between gripping points (distance between the gripping cylinder and the sub gripping portion) can be secured. . Accordingly, it is possible to improve the runout accuracy of the tool.
- the hydraulic chuck has a structure in which a screw to be operated from the outside is provided in the tool body, and the piston is pushed and moved by that screw to generate hydraulic pressure, the nut operation for reducing the diameter of the gripping cylinder and the auxiliary gripping part An operation of a screw for reducing the diameter is required, which complicates the work and lacks practicality.
- the trouble of the tool holder of the present invention in which the piston is interlocked with the movement of the nut is also eliminated.
- the hydraulic chuck has a small transmission loss of force even when the distance from the cylinder to the pressure chamber is large, and the increase in the rotational resistance of the nut can be suppressed to a small extent by configuring the auxiliary gripping portion with the hydraulic chuck.
- the holder's mouth side is made up of a mechanical chuck with a large tightening allowance, so it is easy to grab a tool with large shank diameter variation with rough accuracy control.
- the sub-gripping portion has a smaller tightening margin than the mechanical chuck, but when the tool is inserted into the second tool holding hole, a guiding effect is obtained by the first tool holding hole. Rough tools for precision control are not easily limited.
- the cylindrical accuracy of the thin part of the sleeve constituting the sub gripping part does not greatly affect the deflection accuracy of the gripped tool.

- a tapered sleeve 7 disposed behind the split collar 6 (on the rear end side of the holder), an elastic body (a disc spring in the figure) 8 that biases the tapered sleeve in one direction, and an outer periphery of the sleeve 5 are formed.
- the pressure resistance of the pressure chamber 9, the cylinder 10 formed in the holder body 2, the piston 11 inserted into the cylinder 10, the communication passage 12 that connects the cylinder 10 and the pressure chamber 9, and the rotational resistance of the nut 4 are reduced. It has a friction reducing member 13 (that is a steel ball in the figure).
- a hydraulic fluid is sealed in the cylinder 10, the pressure chamber 9, and the communication passage 12.
- the holder body 2 has a cylindrical gripping cylinder 2a, a body portion 2b, a flange 2c, and a shank 2d, and further has a straight shaft hole 2e and a tapered hole 2f in the center.
- the gripping cylinder 2a and the body 2b are integrally formed. Both of these are fastened with bolts 14 to the end face of the flange 2c which is formed as an independent part and is integrated with the shank 2d.
- the grip cylinder 2a protrudes from the tip of the body 2b and is positioned at the forefront.
- the gripping cylinder 2a has a first tool holding hole a1, a tapered outer peripheral surface a2, and a vertical slit a3.
- the vertical slit a3 is cut in the axial direction from the distal end of the gripping cylinder 2a, and can be reduced in diameter by elastic deformation of the gripping cylinder 2a.
- the body 2b of the tool body is formed with a larger diameter than the gripping cylinder 2a.
- the front end of the body portion 2 b is configured as a plane perpendicular to the axis and faces the back surface of the pressure ring 3.
- the pressure ring 3 is taper-fitted to the outer periphery of the gripping cylinder 2a so as to be slidable in the axial direction.
- the pressure ring 3 is rotatably connected to the nut 4 via a steel ball 15.
- the steel ball 15 is provided with an annular groove having a semicircular cross section facing the outer periphery of the pressure ring 3 and the inner periphery of the nut 4, and half of the steel ball 15 is inserted into one and the other of the opposed annular grooves.
- the insertion opening into the annular groove of the steel ball 15 is closed by a plug 16.
- the nut 4 is provided on the outer periphery of the body portion 2b and the inner periphery of the nut 4 so that a spiral groove having a semicircular cross section is opposed to the friction member 13 and the friction reducing member 13 is inserted into the spiral groove.
- the groove is screwed to the outer periphery of the body portion 2b with the thread valley.
- the sleeve 5 has an annular groove 5a on the outer periphery in the middle of the longitudinal direction.
- the annular groove 5a has a thin portion 5b at the groove bottom and a second tool holding hole 5c at the center.
- This sleeve 5 constitutes a sub-gripping portion, and the distal end side is inserted into the shaft hole 2e of the holder main body behind the gripping cylinder 2a.
- the sleeve 5 has an outer peripheral flange 5d fixed to the body 2b with a screw 19.
- the taper hole 2f provided in the holder body 2 has a small diameter on the back end side.
- the taper sleeve 7 is pushed into the taper hole 2f by the elastic body 8, and thus the rear part of the sleeve 5 having an outer diameter matching the inner diameter of the hole is inserted into the hole at the center of the taper sleeve 7 positioned at the center of the holder body 2. Is inserted and centered in the center of the holder.
- the inner diameter of the second tool holding hole 5c provided in the sleeve 5 is smaller than the free inner diameter of the first tool holding hole a1.
- the pressure chamber 9 is formed by isolating the annular groove 5a on the outer periphery of the sleeve 5 from the shaft hole 2e in a liquid-tight manner.
- the split collar 6 is fitted on the thin portion 5 b in the pressure chamber 9. By installing the split collar 6, the substantial volume of the pressure chamber 9 is reduced, and a high hydraulic pressure can be generated in the pressure chamber 9 even if the moving stroke of the piston 11 is small.
- the cylinder 10 is provided in the body portion 2b with one end opened to the front end of the body portion. Considering the balance of the movement resistance applied to the pressure ring 3 when the nut 4 is tightened and the reduction of the stroke of the piston described later, it is preferable to provide a plurality of cylinders 10 at a constant pitch in the circumferential direction. In the illustrated tool holder, two cylinders 10 are provided, but there may be more.
- the piston 10 is inserted into the cylinder 10 so as to be slidable in the axial direction with a part protruding from the cylinder.
- the piston 11 is pushed into the cylinder 10 by the pressurizing ring 3, the hydraulic fluid filled in the cylinder is compressed.
- the communication passage 12 is provided inside the trunk portion 2 b and communicates the pressure chamber 9 with the cylinder 10. Therefore, when the hydraulic fluid in the cylinder 10 is compressed, a hydraulic pressure is generated in the pressure chamber 9.
- FIG. 4 is a parallel pin fixed to the body 2b and projecting parallel to the axis from the front end of the body.
- the pressure ring 3 is provided with a pin guide hole 21 corresponding to the parallel pin 20 so as to open on the back surface, and the parallel pin 20 is slidably inserted into the pin guide hole 21. For this reason, co-rotation of the pressure ring 3 when the nut 4 is rotated is prevented.
- the parallel pin 20 and the pin guide hole 21 are not essential. When the pressure ring 3 is pressed against the piston 10 while rotating, the piston 10 is twisted. As a countermeasure, the parallel rotation of the pressure ring 3 is prevented by the parallel pin 20 and the pin guide hole 21, but when the pressure ring 3 is pressed against the piston 10, the friction force acting on the contact surface between the two is used. It is not impossible to prevent the pressure ring 3 from rotating together.
- the O-ring 22 is located between the outer periphery of the sleeve 5 and the inner periphery of the shaft hole 2e, the pressure chamber 9 between the grip cylinder 2a and the pressure ring 3, the pressure ring 3 and the nut 4 Between the nut 4 and the body portion 2b, between the outer periphery of the body portion and the inner diameter side of the flange 2c, and between the outer periphery of the sleeve 5 and the inner periphery of the taper sleeve 7, respectively.
- An O-ring at a position excluding a portion for sealing 9 may be provided as necessary.
- the tool holder 1 When the nut 4 is operated in the tightening direction, the tool holder 1 configured as described above moves backward while the nut 4 rotates, and the pressure ring 3 follows the axial movement, and the pressure ring 3 grips the tool holder 1.
- the cylinder 2a is tightened, and the first tool holding hole a1 is reduced in diameter.
- the pressure ring 3 pushes and moves the piston 11, so that a hydraulic pressure is generated in the pressure chamber 9, and the thin portion 5 b of the sleeve 5 is deformed so as to swell inward by the hydraulic pressure, so that the second tool The diameter of the holding hole 5c is reduced, whereby the tool is simultaneously held by the first tool holding hole a1 and the second tool holding hole 5c.
- the shank of the tool is in surface contact with the entire area of the first tool holding hole a1, and thereby, a wide range including the mouth of the holder is obtained. Strong and stable tightening in the area.
- the tool is held by the second tool holding hole 5c behind the gripping cylinder 2a, so that the gripping area is further expanded, the tool deflection accuracy is improved, and the gripping force is further enhanced.
- the piston 11 is pushed and moved by the pressure ring 3. Therefore, the tool can be tightened and released by simply operating the nut 4, and the tool can be easily attached and detached.
