Description

Technical Field

[0001] This invention relates to the field of metal cutting technology, specifically to a quick-change tool with integrated internal cooling function. Background Technology

[0002] Face milling cutters are mainly used for machining flat surfaces. They are characterized by high efficiency, good rigidity, and the ability to use large feed rates. They also have multiple cutting teeth involved in the cutting process, resulting in good working stability. They adopt a rigid tooth structure, making it easy to sharpen and replace the cutting teeth, and extending tool life.

[0003] A Chinese invention with application publication number CN103737091B discloses a cutting tool with a cooling structure, including a tool body, at least one set of tool grooves on the tool body, a cutting insert fixed in the tool grooves by fasteners, a cooling groove leading to the side of the cutting insert between the bottom surface of the cutting insert and the tool grooves, and a cooling channel leading to the cooling grooves on the tool body.

[0004] However, the inventors discovered that the blade body in the above-mentioned device has several sets of blade grooves. Before using the blade, the blades need to be installed step by step, which is cumbersome and inefficient. Based on this, the inventors proposed a quick-change blade with integrated internal cooling function. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a quick-change tool with integrated internal cooling. This is achieved by incorporating a first locking component within the tool groove, a rotating sleeve rotatably mounted on the inner wall of the tool body, a switching component within the rotating sleeve, and a cooling component within the switching component. The tool body is equipped with a second locking component for locking the rotating sleeve and an unlocking component for unlocking the rotating sleeve. The rotating sleeve drives the first locking component to install the inserts in batches, and the second locking component limits the rotation of the sleeve. This invention simplifies the installation process and saves time by enabling batch installation of inserts. Furthermore, its cooling component not only impacts and cuts the filaments generated during cutting but also washes away debris while cooling the tool, thus solving the problem of conventional cooling tools having limited functionality.

[0006] To address the aforementioned technical problems, the present invention adopts the following technical solution:

[0007] A quick-change tool with integrated internal cooling function includes a tool body and a plurality of tool slots formed along the circumference of the tool body. A cutting insert is installed in each tool slot via a first locking assembly. A rotating sleeve is rotatably mounted on the inner wall of the tool body. A switching assembly is housed within the rotating sleeve, and a cooling assembly is housed within the switching assembly. The tool body is respectively provided with a second locking assembly for locking the rotating sleeve and an unlocking assembly for unlocking the rotating sleeve. The rotating sleeve drives the first locking assembly to install the cutting inserts in batches via rotation, and the second locking assembly limits the movement of the rotating sleeve.

[0008] As a preferred embodiment, the first locking assembly includes a cavity disposed inside the tool body and communicating with the tool groove, a first pull rod slidably disposed in the cavity, an annular groove disposed at the tail end of the first pull rod, a second pull rod disposed perpendicular to the first pull rod, and a tapered groove disposed at one end of the second pull rod.

[0009] As a preferred embodiment, a limiting ring is provided at the other end of the first pull rod, and a plurality of conical protrusions are provided on the inner side of the limiting ring. A plurality of conical grooves are provided at the point where the blade abuts against the limiting ring, and the edges of both ends of the conical grooves are provided with arc-shaped chamfers.

[0010] As a preferred embodiment, a gasket is provided at one end of the blade, and a magnetic piece is provided at the point where the blade groove abuts against the gasket.

[0011] As a preferred embodiment, the switching assembly includes a first groove disposed on the side of the rotating sleeve, a sliding plate slidably disposed within the first groove, a first hemispherical valve fixedly disposed on the sliding plate, a second hemispherical valve rotatably disposed within the first hemispherical valve, and a connecting rod disposed on the second hemispherical valve.

[0012] As a preferred embodiment, the outer side of the end of the connecting rod is provided with a slider, the second pull rod is hollow, and the inner wall of the second pull rod is provided with a second sliding groove that cooperates with the slider.

[0013] As a preferred embodiment, the cooling assembly includes a plurality of water injection holes disposed on the inner wall of the rotating sleeve, a first water passage hole disposed in the middle of the sliding plate and communicating with the first hemispherical valve, a second water passage hole disposed at both ends of the annular groove, a water storage tank disposed in the gasket, a plurality of first water outlet holes disposed on the outer side of the gasket, and a second water outlet hole disposed at the other end of the cavity.

[0014] As a preferred embodiment, the water outlet of the second water outlet is inclined upward, and a high-pressure nozzle is provided on the second water outlet.

[0015] As a preferred embodiment, the second locking assembly includes a first rectangular groove disposed within the rotating sleeve, a rectangular block slidably disposed within the first rectangular groove, a spring disposed between the rectangular block and the first rectangular groove, and a second rectangular groove disposed on the tool body corresponding to the first rectangular groove.

[0016] As another preferred embodiment, the unlocking component includes an annular cavity disposed on the tool body, an arc-shaped block slidably disposed within the annular cavity, an inclined surface disposed on the lower end face of the arc-shaped block, a connector disposed on the upper end face of the arc-shaped block, a plug hinged to the connector, and a slot disposed on the upper end face of the tool body.

[0017] The beneficial effects of this invention are:

[0018] In this invention, the blade is placed in the blade groove, and the first pull rod is limited by the movement of the second pull rod. The second pull rod is then limited by the second locking assembly, which enables the batch installation of the blade, simplifies the blade installation steps, and saves time and costs.

[0019] The cooling component of this invention has two outlets for the coolant. The first outlet sprays out a large amount of coolant to cool and lubricate the blades and wash away the chips generated during cutting. The second outlet is equipped with a high-pressure nozzle that impacts and cuts the fine filaments generated by the cutting of a nearby set of blades, so that the coolant can wash them away.

[0020] In summary, this equipment has advantages such as convenient installation, good cooling effect, and clean chip removal, and is especially suitable for the field of metal cutting technology. Attached Figure Description

Detailed Implementation

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0039] Example 1

[0040] In this embodiment, as Figures 1 to 15 As shown, a quick-change tool with integrated internal cooling function includes a tool body 1 and a plurality of tool slots 2 formed along the circumference of the tool body 1. A cutting blade 4 is installed in the tool slot 2 via a first locking assembly 3. A rotating sleeve 5 is rotatably disposed on the inner wall of the tool body 1. A switching assembly 6 is disposed within the rotating sleeve 5, and a cooling assembly 7 is disposed within the switching assembly 6. A second locking assembly 8 for locking the rotating sleeve 5 and an unlocking assembly 9 for unlocking the rotating sleeve 5 are respectively disposed on the tool body 1. The rotating sleeve 5 drives the first locking assembly 3 to install the cutting blades 4 in batches by rotation, and the second locking assembly 8 limits the position of the rotating sleeve 5.

[0041] In addition, such as Figures 3 to 4 As shown, the first locking assembly 3 includes a cavity 31 disposed inside the cutter body 1 and communicating with the cutter groove 2, a first pull rod 32 slidably disposed in the cavity 31, an annular groove 33 disposed at the tail end of the first pull rod 32, a second pull rod 34 disposed perpendicular to the first pull rod 32, and a conical groove 35 disposed at one end of the second pull rod 34. In this invention, the conical groove 35 on the second pull rod 34 abuts against one end of the annular groove 33 and limits its movement, preventing the first pull rod 32 from moving and affecting the fixing effect on the blade 4.

[0042] In this embodiment, as Figure 6 As shown, a limiting ring 36 is provided at the other end of the first pull rod 32. A plurality of conical protrusions 37 are provided on the inner side of the limiting ring 36. A plurality of conical grooves 38 are provided at the point where the blade 4 abuts against the limiting ring 36. The edges of both ends of the conical grooves 38 are provided with arc-shaped chamfers. In this invention, when the conical protrusions 37 abut against the wall of the conical grooves 38 or the arc-shaped chamfers, when the first pull rod 32 is driven to move by the second pull rod 34, the conical protrusions 37 will slide into the conical grooves 38. The cooperation between the conical grooves 38 and the conical protrusions 37 can prevent the first pull rod 32 from rotating, thus concealing the fixing effect of the blade 4.

[0043] It is worth mentioning here that, as Figure 7 As shown, a pad 41 is provided at one end of the blade 4, and a magnetic piece 42 is provided at the point where the blade groove 2 abuts against the pad 41. In this invention, the blade 4 and the pad 41 are placed in the blade groove 2 manually, and are temporarily fixed by the attraction of the magnetic piece 42.

[0044] In addition, such as Figure 5As shown, the switching component 6 includes a first sliding groove 61 disposed on the side of the rotating sleeve 5, a sliding plate 62 slidably disposed in the first sliding groove 61, a first hemispherical valve 63 fixedly disposed on the sliding plate 62, a second hemispherical valve 64 rotatably disposed in the first hemispherical valve 63, and a connecting rod 65 disposed on the second hemispherical valve 64. In this invention, when the rotating sleeve 5 rotates, the second pull rod 34 drives the sliding plate 62 to slide in the first sliding groove 61, and the second hemispherical valve 64 rotates and adjusts its direction in the first hemispherical valve 63, so that the second pull rod 34 moves.

[0045] It needs to be emphasized that, such as Figure 5 As shown, a slider 66 is provided on the outer side of the end of the connecting rod 65, the second pull rod 34 is hollow, and the inner wall of the second pull rod 34 is provided with a second sliding groove 67 that cooperates with the slider 66; the present invention allows the second pull rod 34 to slide in the second sliding groove 67, and the second sliding groove 67 provides a small range of movement path for the movement of the second pull rod 34.

[0046] In addition, such as Figures 3 to 12 As shown, the cooling assembly 7 includes several water injection holes 71 disposed on the inner wall of the rotating sleeve 5, a first water passage hole 72 disposed in the middle of the sliding plate 62 and communicating with the first hemispherical valve 63, a second water passage hole 73 disposed at both ends of the annular groove 33, a water storage tank 74 disposed in the gasket 41, several first water outlet holes 75 disposed on the outer side of the gasket 41, and a second water outlet hole 76 disposed at the other end of the cavity 31; the water outlet direction of the second water outlet hole 76 is inclined upward, and a high-pressure nozzle is disposed on the second water outlet hole 76; in this invention, the coolant enters from the water injection hole 71 and exits from the first water outlet hole 75 and the second water outlet hole 76. The first water outlet hole 75 sprays out a large amount of coolant to cool and lubricate the blade 4 and to wash away the chips generated during cutting. The second water outlet hole 76 is disposed on the high-pressure nozzle, which impacts and cuts off the fine filaments generated by the cutting of a group of adjacent blades 4, so that the coolant can wash them away.

[0047] It needs to be emphasized that, such as Figure 9 As shown, the second locking assembly 8 includes a first rectangular groove 81 disposed in the rotating sleeve 5, a rectangular block 82 slidably disposed in the first rectangular groove 81, a spring 83 disposed between the rectangular block 82 and the first rectangular groove 81, and a second rectangular groove 84 disposed on the tool body 1 corresponding to the first rectangular groove 81; the present invention fixes the rotating sleeve 5 by pressing the rectangular block 82 into the second rectangular groove 84 under the action of the spring 83.

[0048] It is worth mentioning here that, as Figure 10As shown, the unlocking component 9 includes an annular cavity 91 disposed on the tool body 1, an arc-shaped block 92 slidably disposed within the annular cavity 91, an inclined surface 93 disposed on the lower end face of the arc-shaped block 92, a connector 94 disposed on the upper end face of the arc-shaped block 92, a plug 95 hinged to the connector 94, and a slot 96 disposed on the upper end face of the tool body 1. The present invention achieves unlocking by pressing the connector 94 and the arc-shaped block 92 downwards, and the inclined surface 93 on the arc-shaped block 92 presses the rectangular block 82 into the first rectangular slot 81, and rotating the rotating sleeve 5.

[0049] The work process is as follows:

[0050] The gasket 41 and the blade 4 are placed in the blade groove 2 by hand, and temporarily fixed by the attraction of the magnetic plate 42. The first pull rod 32 passes through the blade 4 and the gasket 41 and is placed in the cavity 31.

[0051] Rotating the rotating sleeve 5 causes the second pull rod 34 to drive the sliding plate 62 to slide within the first sliding groove 61. The second hemispherical valve 64 rotates within the first hemispherical valve 63 and adjusts its direction, causing the second pull rod 34 to move. When the conical protrusion 37 abuts against the wall of the conical groove 38 or the arc-shaped chamfer, the conical protrusion 37 will slide into the conical groove 38 when the second pull rod 34 drives the first pull rod 32 to move. The cooperation between the conical groove 38 and the conical protrusion 37 can prevent the first pull rod 32 from rotating.

[0052] By the force of the spring 83, the rectangular block 82 is pressed into the second rectangular groove 84, thus fixing the rotating sleeve 5;

[0053] Coolant is introduced into the tool holder. The coolant flows in from the water inlet 71, passes through the middle of the second pull rod 34, and flows out through the first water outlet 75 and the second water outlet 76 to cool the tool.

[0054] To release the limit of the rotating sleeve 5, the connector 94 and the arc-shaped block 92 are pressed downwards. The inclined surface 93 on the arc-shaped block 92 presses the rectangular block 82 and presses it into the first rectangular groove 81. The rotating sleeve 5 is then rotated to unlock the sleeve.

[0055] Of course, those skilled in the art should understand that the term "a" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple. The term "a" should not be understood as a limitation on the quantity.

[0056] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art under the technical guidance of the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
