The present invention will be described in detail with reference to the accompanying drawings and examples.

Referring to fig. 1 and 2, the first embodiment of the present invention comprises a cutter bar 1, four rings disposed on the side blades 2 (fig. 1 only shows two for showing the angle) on the outer periphery of the cutter bar 1, two sleeves disposed on the cutter bar 1, a tuning ring 3 disposed on one end of the cutter bar 1, a cutting member 4 disposed on one end of the cutter bar 1, and a locking member 5 disposed on the cutter bar 1 and the cutting member 4.

The tool bar 1 includes a main body 11 extending up and down along an axis L, and an extending portion 12 extending down from one end of the main body 11 along the axis L. The body portion 11 has two outer threaded surfaces 111 that are spaced apart in the direction of the axis L around the axis L and face in the radial direction. The main body 11 is recessed from the external thread surface 111 to form a plurality of insert pockets 110 extending along the axis L and arranged at intervals around the axis L. Each insert pocket 110 is defined by a radially facing abutment surface 112 and two radially extending side surfaces 113 (only one is shown in fig. 1) that engage with each other on opposite sides of the abutment surface 112. The depth of each insert pocket 110 in the radial direction increases downward along the extending direction of the axis L, and specifically, the distance from the abutting surface 112 to the axis L along the direction perpendicular to the axis L decreases downward along the extending direction of the axis L. The extension portion 12 has an extension main body 126 extending from the main body 11 along the axis, an extension screw surface 121 engaging with one of the outer screw surfaces 111, two protrusions 122 projecting from the end of the extension main body 126 along the direction of the axis L away from the main body 11 at intervals, a first inner ring surface 123 opposite to the extension screw surface 121 and surrounding the axis L, and a second inner ring surface 124 extending from the first inner ring surface 123 upward along the axis L and forming a thread. The first inner annular surface 123 surrounds and defines a positioning groove 120 between the protrusions 122, and the second inner annular surface 124 surrounds and defines an inner threaded hole 125 communicating with the positioning groove 120 and having an inner diameter smaller than that of the positioning groove 120.

Referring to fig. 3 to 5 in conjunction with fig. 1, the side blades 2 extend along the direction of the axis L and are respectively assembled in the blade grooves 110. Each side blade 2 includes a cutter body portion 21 extending in the direction of the axis L, a reamer edge 22 provided on one side of the cutter body portion 21 in the circumferential direction of the cutter bar 1, and a hob edge 23 provided on one side of the cutter body portion 21 in the radial direction of the cutter bar 1 and spaced from the reamer edge 22 in the direction of the axis L1. It should be noted that the material of the side blade 2 is preferably tungsten steel with high hardness, high toughness, wear resistance, corrosion resistance, heat resistance and less adhesion of chips, but not limited thereto. The cutter body portion 21 has a first face 211 facing outward and provided for the hinge blade 22, a second face 212 spaced above the first face 211 and provided for the rolling blade 23, an inclined face 213 facing the corresponding insert pocket 110 opposite to the first face 211 and the second face 212 and extending obliquely in the extending direction of the axis L corresponding to the insert pocket 110, a transition face 214 between the first face 211 and the second face 212, a first engagement face 215 engaging the first face 211 and the transition face 214, and a second engagement face 216 engaging the second face 212 and the transition face 214. The transition surface 214, the first engagement surface 215 and the second engagement surface 216 of each side insert piece 2 cooperate to define a clearance hole 20 through which swarf may pass.

The distance of the roller cutting edge 23 of each side blade 2 to the axis L in the radial direction of the holder 1 is slightly greater than the distance of the reamer cutting edge 22 to the axis L in the radial direction of the holder 1. From the perspective of the axis L, the outer edge of each hob edge 23 is curved as shown in fig. 3 and has three hob sections 231 for contacting the bore wall and engaging each other, the curvature of each hob section 231 may be the same or different. The shape of each side insert 2 in the first embodiment can be adjusted corresponding to the corresponding insert slot 110, so that the distance from the inclined surface 213 to the first surface 211 along the radial direction of the tool holder 1 is greater than the distance from the inclined surface 213 to the second surface 212 along the radial direction of the tool holder 1. For convenience of description, the relative positions of the first surface 211, the inclined surface 213, and the hob edge 23 will be described by defining the second surface 212 as an independent object. However, in practical cases, the second surface 212 is covered by the hob edge 23, and is indicated by an imaginary line in fig. 3.

Referring to fig. 5 to 6, it should be particularly noted that, in the first embodiment, when each side insert 2 is operated to move upward along the insert slot 110, the distance from the abutting surface 112 contacting the inclined surface 213 to the axis L along the radial direction of the tool holder 1 increases, so that the side insert 2 simultaneously moves away from the axis L as shown in fig. 6 and protrudes outward along the radial direction of the tool holder 1. Conversely, when each side insert 2 is operated to move down along the insert pocket 110, the distance from the abutting surface 112 contacting the inclined surface 213 to the axis L in the radial direction of the holder 1 decreases gradually, so that the side inserts 2 approach the axis L simultaneously as shown in fig. 7 and are retracted inward in the radial direction of the holder 1.

Referring to fig. 1 and fig. 2 again, the adjusting ring 3 is sleeved on the cutter bar 1 at intervals and is used for pushing against two ends of the side blade 2 respectively, so that the side blade 2 is fixed to the cutter bar 1. Each adjustment ring 3 has an inner screw surface 31 for screwing the outer screw surface 111 and the extension screw surface 121, and is operable to reciprocate on the tool bar 1 in the extension direction of the axis L. Each adjustment ring 3 and the main body 11 cooperate to define an annular space 310 into which one end of the side blade 2 can be inserted, so that when the adjustment ring 3 pushes against one end of the side blade 2, the side blade 2 can be fixed and the side blade 2 is prevented from being separated from the blade groove 110.

The cutting element 4 is detachably connected to the extension 12 of the tool holder 1 and located below the side insert 2, and a distance from the outer edge shown in fig. 2 to the axis L along the radial direction of the tool holder 1 is smaller than a distance from the first surface 211 to the axis L along the radial direction of the tool holder 1, so as to perform a pre-drilling operation, thereby facilitating a subsequent operation of the side insert 2. The cutting element 4 has a cutting head 41 extending along the axis L and forming a ring shape to surround and define a through hole 411, two positioning blocks 42 protruding from the cutting head 41 along the axis L toward the cutter bar 1 for inserting the positioning slot 120, and a plurality of cutting edges 43 disposed on the outer periphery of the cutting head 41. The end surface of the cutting head 41 facing the extension portion 12 is recessed inwards to form two grooves 410 for the protrusion 122 to be embedded respectively, so that the cutting head 41 and the cutter bar 1 are combined with each other to rotate coaxially, and the idle rotation condition that the cutting head 41 and the cutter bar 1 slide relatively is avoided. Particularly, the positioning block 42 is inserted into the positioning groove 120 and abuts against the first inner annular surface 123, so that the concentricity between the tool bit 41 and the tool bar 1 can be maintained, and the tool bit 41 is prevented from being inclined to the axis L and being tilted when rotating. It should also be noted that the cutting element is preferably a milling or reaming head, whereby different drilling requirements are met.

The locking member 5 extends along the axis L, and can be simultaneously inserted through the cutting element 4 and the extension 12 of the tool holder 1 along the direction of the axis L, so as to fix the cutting element 4 on the tool holder 1. The locking member 5 includes a long rod portion 51 that can penetrate through the through hole 411, and a threaded portion 52 that extends from one end of the long rod portion 51 and forms an external thread for being screwed into the internal thread hole 125. The locking member 5 is preferably a screw, but not limited thereto.

When assembling the first embodiment, the inclined surfaces 213 are first respectively faced to the abutting surfaces 112 to place the side insert 2 in the insert pocket 110, and the position of the side insert 2 along the direction of the axis L is adjusted, so that the distances from the first surface 211 and the second surface 212 to the axis L can be adjusted simultaneously, thereby facilitating the machining requirements of different inner diameters. The user rotates the adjusting ring 3 to move up and down along the direction of the axis L until pushing against the opposite ends of the side blade 2, and the upper and lower ends of the side blade 2 are respectively inserted into the annular space 310, so that the side blade 2 can be fixed on the cutter bar 1. Finally, the positioning block 42 of the cutting element 4 is inserted into the positioning groove 120 of the extension portion 12, the protrusion 122 of the extension portion 12 is embedded in the groove 410 of the extension portion 12, and the locking element 5 penetrates through the cutting element 4 and is screwed into the inner threaded hole 125, so that the cutting element 4 is fixed on the tool bar 1 along the direction of the axis L.

Referring to fig. 8, in the first embodiment, after the cutting element 4 is aligned with a desired drilling position, the cutter bar 1 is rotated to drive the cutting element 4 to rotate around the axis L, and a hole a is drilled by a cutting force generated by a moment generated when the cutting edge 43 of the cutting element 4 rotates, thereby completing a pre-drilling operation. It should be noted that, when the position of the hole to be drilled is not a perfect circle, the cutting member 4 rotating around the axis L as a rotation axis can effectively cut, so that the hole a forms a perfect circle for subsequent operations. Then, while the cutter 4 drills the hole a, the side blade 2 is rapidly rotated around the axis L, so that the reamer blade 22 cuts the hole a in the circumferential direction and advances in the direction of the axis L, thereby enlarging the inner diameter of the hole a to achieve the first hole enlargement for roughing. Meanwhile, when the hob edge 23 contacts an inner wall B of the hole a, the hob edge 23 presses the inner wall B along the radial direction of the tool bar 1, thereby compressing the density of the inner wall B, and expanding the inner diameter of the hole a to a required inner diameter range again, thereby achieving a second reaming of the fine machining.

Through the spatial structure that the hinge cutting edge 22 and the rolling cutting edge 23 of each side blade 2 are distributed along the direction of the axis L, the hole A can be subjected to integral reaming operation of firstly hinging and then rolling, so that the inner diameter of the hole A can be uniform along the direction of the axis L, and the required inner diameter size can be accurately achieved. In addition, by using the design that the depth of the insert pocket 110 is different along the extending direction of the axis L, and the structure that the inclined surface 213 is inclined to the extending direction of the axis L, the distance from each reamer 22 and each hob edge 23 to the axis L along the radial direction of the cutter bar 1 can be adjusted, thereby satisfying different processing environments and requirements and improving the product applicability.

It should be noted that, the cutting element 4 of the first embodiment may be assembled to the structural design of the tool holder 1, so that the cutting element 4 with different specifications can be replaced according to different machining requirements, thereby further improving the applicability of the product. In addition, through the locating piece 42 is inserted and is located the constant head tank 120, and cooperate simultaneously the lug 122 inlays and locates the connection structure in the recess 410, can not only prevent cutting member 4 with relative slip between the cutter arbor 1 to this avoids the condition of idle running, can also maintain cutting member 4 with the concentricity between the cutter arbor 1, avoids cutting member 4 to produce the crooked condition when rotating, borrows this promotion precision of processing.

Referring to fig. 9 and 10, a second embodiment of the roll finishing reamer integrated tool of the present invention is different from the first embodiment in that: the depth of each insert pocket 110 increases upward along the extension of the axis L. The distance from the inclined surface 213 of each side insert piece 2 to the first surface 211 in the radial direction of the holder 1 is smaller than the distance from the inclined surface 213 to the second surface 212 in the radial direction of the holder 1.

By the second embodiment of the insert pocket 110 being in a manner opposite to that of the first embodiment of the side insert 2, the tendency of the outer diameter to taper up and down as the side insert 2 moves up and down along the axis L is opposite to that of the first embodiment, thereby meeting different operational requirements.

Referring to fig. 11, a third embodiment of the roll finishing reamer integrated tool of the present invention is different from the first embodiment in that: the reamer edge 22 of each side blade 2 tapers in the direction of extension of the axis L in the radial direction of the tool shank 1 (see fig. 1) to the axis L. For simplicity, fig. 11 omits some components, and only the axis L and one side blade 2 are shown for representing a state in which the reamer blade 22 is shifted along the axis L.

By the design that each reamer 22 is inclined to the axis L and gradually expands, the hole a (see fig. 8) can be reamed without a step, so that the hole a is gradually enlarged along the radial direction of the cutter bar 1, the occurrence of excessive abrasion of the reamer 22 is avoided, and the service life is prolonged. In addition, the third embodiment can also be modified by the side blade 2 of the second embodiment for matching different operation requirements.

Referring to fig. 12, a fourth embodiment of the present invention is a rolling reamer integrated tool, which is different from the first embodiment in the structural difference between the extension 12 and the cutting member 4. The extension portion 12 has an extension thread surface 121 engaging one of the outer thread surfaces 111, a first inner thread surface 123 opposite to the extension thread surface 121 and surrounding the axis L, and a second inner thread surface 124 extending upward from the first inner thread surface 123 along the axis L and forming a thread. The first inner annular surface 123 defines a positioning groove 120 and the second inner annular surface 124 defines an inner threaded hole 125 facing the cutting element 4. The cutting element 4 has a cutting head 41 extending along the axis L and having a ring shape, a positioning portion 44 protruding from the cutting head 41 along the axis L toward the cutter bar 1 for being disposed in the positioning groove 120, a fastening portion 45 protruding from the positioning portion 44 along the axis L toward the cutter bar 1 for being screwed into the internal screw hole 125, and a cutting edge 43 disposed on the outer periphery of the cutting head 41. The screw fastening portion 45 can be operatively screwed into the inner screw hole 125 to achieve a fixing effect, which is easy to manufacture and further improves the assembling convenience.

It should be noted that, without limitation to the form of the internal screw hole 125, the form of the screw portion 45 may correspond to the thread form of the internal screw hole 125, while the design specification of different plants, such as ACME (ACME), may correspond to different design specifications.
