Description

Technical Field

[0001] This application relates to the field of machine tool technology, and in particular to a tool magazine and a CNC machine tool. Background Technology

[0002] Modern CNC machine tools are typically equipped with a tool magazine. With the help of a tool changer, the tools stored in the tool magazine can be exchanged with the tools used on the spindle.

[0003] The tools in the tool magazine are mounted on the tool magazine body via tool holders, tool claws, or tool supports. To facilitate the maintenance or replacement of tools in the tool magazine, some CNC machine tools are equipped with tool holders that can move relative to the tool magazine body and thus detach from the tool magazine, such as Chinese patent document CN221517012U.

[0004] The fact that the tool holder can move relative to the tool magazine body presents a new challenge: how to lock the tool holder's position relative to the tool magazine body to prevent it from moving and falling off. In the technical solution provided in the aforementioned patent literature, the tool holder seat has a resilient, recessed clip that engages with a groove or other structure on the tool holder to lock the tool holder's installation position.

[0005] However, to ensure a relative locking effect in the sheath's installation position, the outer surface of the sheath in the above-mentioned technical solution must be equipped with a limiting structure that matches the shape of the magazine's clamping part; that is, it requires a specially made sheath. If a regular sheath with a non-specialized outer surface is used, the locking effect will be significantly reduced. Furthermore, this technical solution lacks guidance for the initial installation of the sheath. Utility Model Content

[0006] The embodiments of this application aim to at least solve one of the problems of the prior art. The embodiments of this application provide a tool magazine and CNC machine tool that improve the versatility of the tool holder while meeting the requirements of both movable and lockable tool holders, and provide a guiding function for installing the tool holder body.

[0007] The relevant technical solutions of the embodiments of this application include the following:

[0008] A first aspect of this application provides a tool magazine. The tool magazine includes a tool magazine body and tool sleeves. A plurality of tool sleeves are circumferentially distributed along the outer edge of the tool magazine body. Each tool sleeve includes a tool sleeve body and a tool sleeve base. The tool sleeve base includes a seat and two opposing guide structures. The tool sleeve body has sliding structures on both sides adapted to the guide structures. The tool sleeve body is movable relative to the guide structures. At least one guide structure is rotatably connected to the seat. An elastic element is connected between the two guide structures or between the rotatably connected guide structures and the seat, and the elastic element is used to drive the extended ends of the two guide structures to move closer together.

[0009] Optionally, at least one of the guide structures is rotatably connected to the base via a hinge shaft;

[0010] Wherein, the elastic element is a compression spring, which is located on the side of the hinge shaft away from the extended end of the guide structure; or, the elastic element is a tension spring, which is located on the side of the hinge shaft close to the extended end of the guide structure.

[0011] Optionally, the tool holder seat is further provided with a limiting post, wherein the limiting post is located on the side of the hinge shaft near the protruding end of the guide structure, and the limiting post is tightly against the inner side of the rotatably connected guide structure; and / or

[0012] The limiting post is located on the side of the hinge shaft away from the extended end of the guide structure, and the limiting post is in close contact with the outer side of the rotatably connected guide structure.

[0013] Optionally, the elastic element is located between the blade sheath body and the base body, and the side of the blade sheath body facing the base body of the blade sheath seat is an integrally concave curved surface or has an avoidance groove to form a first avoidance space.

[0014] Optionally, the distance d between the line connecting the two ends of the elastic element and the hinge axis satisfies: Where l is the distance from the hinge shaft to the extended end of the guide structure.

[0015] Optionally, the guide structure includes a first guide portion, a second guide portion, and a third guide portion distributed sequentially along its own extension direction, wherein the first guide portion is close to the seat body and is hinged to the seat body via a hinge axis.

[0016] Optionally, the sliding structure is a sliding groove, and the guiding structure is a guide rib adapted to the sliding groove, wherein the cross-section of the third guiding portion of the guide rib structure gradually decreases along its own extension direction; or, the sliding structure is a sliding rib, and the guiding structure is a guide groove adapted to the sliding rib, wherein the slotted cross-section of the third guiding portion of the guide groove structure gradually increases along its own extension direction.

[0017] Optionally, in the initial state of the two guide structures, the extension directions of the inner guide surfaces of the two second guide portions converge inwards towards each other, and the extension directions of the inner guide surfaces of the two third guide portions open outwards towards each other.

[0018] Optionally, the tool magazine is a disc-type tool magazine. The tool magazine body includes a disc body, a support structure, and a tool disc base. The disc body and the tool disc base are connected through the support structure. The support structure includes multiple support ribs. The support ribs extend vertically upward from the outer edge of the tool disc base and then continue to extend upward to the outer edge of the disc body in an inclined upward and outward diverging manner.

[0019] A second aspect of this application provides a CNC machine tool. The CNC machine tool includes the tool magazine described in any of the foregoing embodiments.

[0032] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the accompanying drawings used in the description of the embodiments of this application or the prior art will be briefly introduced below.

[0033] Obviously, the accompanying drawings described below are merely some embodiments of this application. Those skilled in the art can obtain drawings of other embodiments based on the technical solutions illustrated in these drawings without any inventive effort.

[0034] It should be understood that "multiple" as used herein refers to two or more. In the description of this application, unless otherwise stated, " / " means "or", for example, "A / B" means A or B; "and / or" in this document is merely a description of the relationship between related objects, and it can represent three relationships, for example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, B exists alone, etc.

[0035] Furthermore, in order to clearly describe the technical solutions of the embodiments of this application, the terms "first" or "second" are used in the embodiments of this application to distinguish identical or similar items with substantially the same function and effect. Those skilled in the art will understand that the terms "first" and "second" do not limit the quantity or execution order, and the terms "first" and "second" are not necessarily different.

[0036] The terms "installation," "connection," and "setting" mentioned in the embodiments of this application include direct installation / connection / setting as well as indirect installation / connection / setting; detachable installation / connection / setting as well as non-detachable installation / connection / setting; fixed installation / connection / setting as well as movable installation / connection / setting.

[0037] This application uses a disc-type tool magazine as an example to introduce the technical solutions of the embodiments of this application. However, it should be understood that the application of some technical solutions of the embodiments of this application is not limited to disc-type tool magazines.

[0038] Please see Figures 1 to 5 The first aspect of this application provides a tool magazine. For example... Figure 1 As shown, the tool magazine includes a tool magazine body 10 and tool holders 20, with multiple tool holders 20 distributed circumferentially along the outer edge of the tool magazine body 10. Specifically, for a disc-type tool magazine, the tool magazine body 10 is the tool disc, and multiple tool holders 20 are distributed along the outer edge of the tool disc.

[0039] like Figure 2 As shown, the tool holder 20 includes a tool holder body 210 and a tool holder base 220. The tool holder base 220 includes a base 224 and two opposing guide structures 221. Specifically, the base of the tool holder base 220 extends in a direction away from the center of the tool magazine body 10 to form two guide structures 221, wherein "extending in a direction away from the center of the tool magazine 10" does not require that the reverse extension lines of the two guide structures 221 converge at the center of the tool magazine 10. The tool holder body 210 has sliding structures on both sides that are adapted to the guide structures 221, allowing the tool holder body 210 to move relative to the guide structures 221. The sliding structures and guide structures 221 together form a groove and slider (or slider and groove) fit.

[0040] At least one guide structure 221 is rotatably connected to the base 224 of the tool holder 220. An elastic element 223 is connected between the two guide structures 221 or between the rotatably connected guide structure 221 and the base 224. The elastic element 223 is used to drive the extended ends of the two guide structures 221 to move closer to each other.

[0041] As mentioned earlier, in existing technical solutions, to ensure the locking effect of the tool holder installation position, the outer surface of the tool holder body must be provided with a limiting structure that matches the shape of the clamping part of the locking structure (such as a magazine), thus imposing specific requirements on the tool holder body to which it is adapted. Tool holder bodies that do not meet the specific requirements will not be suitable for the tool magazine body in this technical solution.

[0042] In the embodiments of this application, two guide structures 221 on the tool holder 220 are arranged opposite to each other, wherein at least one guide structure 221 can rotate relative to the base of the tool holder 220, so that the distance and included angle between the two guide structures 221 can be adjusted as needed, thereby facilitating the initial operation of installing the tool holder body 210 on the tool holder 220. The sliding structure of the tool holder body 210 is located inside the guide structure 221 of the tool holder 220. An elastic element 223 is also connected between the two guide structures 221 or the rotatably connected guide structure 221 and the base 224 of the tool holder 220. The elastic element 223 is used to drive the protruding ends of the two guide structures 221 to move closer to each other. Under the action of the elastic restoring force of the elastic element 223, the guide structure 221 can clamp the tool holder body 210 to a certain extent, thereby preventing the tool holder body 210 from easily sliding out of the tool holder 220. Thus, even if the tool holder body 210 is general-purpose rather than specially made, it can be used in this tool magazine. The technical solution of this application improves the versatility of the tool holder while satisfying the requirement that the tool holder can be moved and locked, and provides a guiding function for installing the tool holder body.

[0043] Furthermore, in some embodiments of this application, at least one guide structure 221 is rotatably connected to the seat 224 via a hinge shaft 222; wherein, as... Figure 3 As shown, the elastic element 223 is a tension spring, which is located on the side of the hinge shaft 222 near the protruding end of the guide structure 221; or, as Figure 4 As shown, the elastic element 223 is a compression spring, which is located on the side of the hinge shaft 222 away from the extended end of the guide structure 221.

[0044] Furthermore, in some embodiments of this application, the tool holder 220 is also provided with a limiting post 225, wherein the limiting post 225 is located on the side of the hinge shaft 222 near the protruding end of the guide structure 221, and the limiting post 225 is in close contact with the inner side of the rotatably connected guide structure 221; and / or, the limiting post 225 is located on the side of the hinge shaft 222 away from the protruding end of the guide structure 221, and the limiting post 225 is in close contact with the outer side of the rotatably connected guide structure 221.

[0045] Specifically, in Figure 3In this configuration, only the right-side guide structure 221 can rotate relative to the base 224. The two ends of the elastic element 223 are connected to the right-side guide structure 221 and the base 224, respectively. It is understood that the two ends of the elastic element 223 can also be connected to the right-side guide structure 221 and the left-side guide structure 221, respectively. With the hinge shaft 222 as the fulcrum of rotation, the right-side guide structure 221 opens relatively on the side away from the protruding end of the guide structure 221, and closes relatively on the side closer to the protruding end of the guide structure 221. This further facilitates guidance during the initial installation of the tool holder body 210 onto the tool holder base 220 (in the initial installation phase, the tool holder body 210 and the tool holder base 220 meet on the side closer to the protruding end of the guide structure 221), thus facilitating the installation of the tool holder body 210. Figure 3 As shown, a limiting post 225 is provided on the side of the hinge shaft 222 away from the protruding end of the right-side guide structure 221. This limiting post 225 is also located on the outer side of the right-side guide structure 221. The provision of the limiting post 225 helps to prevent the right-side guide structure 221 from opening excessively on the side away from the protruding end of the guide structure 221 and closing excessively on the other side. It can be understood that if a limiting post 225 is provided on the side of the hinge shaft 222 near the protruding end of the right-side guide structure 221, and this limiting post 225 is also located on the inner side of the right-side guide structure 221, a similar technical effect can be achieved.

[0046] exist Figure 4 In the middle, both left and right guide structures 221 can rotate relative to the base 224. The two ends of the elastic element 223 are respectively connected to the two guide structures 221. With the hinge shaft 222 as the fulcrum of rotation, the two guide structures 221 open relative to each other on the side away from the extended end of the guide structure 221, and close relative to each other on the side closer to the extended end of the guide structure 221. For example... Figure 4 As shown, a limiting post 225 is provided on the side of the hinge shaft 222 away from the protruding end of the guide structure 221. This limiting post 225 is also located on the outer side of both guide structures 221. The provision of the limiting post 225 helps to prevent the two guide structures 221 from opening excessively on the side away from the protruding end of the guide structure 221 and closing excessively on the other side. It can be understood that if the limiting post 225 is provided on the side of the hinge shaft 222 near the protruding end of the guide structure 221, and this limiting post 225 is also located on the inner side of both guide structures 221, a similar technical effect can be achieved.

[0047] Furthermore, in some embodiments of this application, the elastic element 223 is located between the blade sheath body 210 and the seat 224 of the blade sheath base 220, and the side of the blade sheath body 210 facing the seat 220 is an integrally concave curved surface or has a clearance groove to form a first clearance space for accommodating the elastic element 223. The placement position of the elastic element 223 will occupy the installation space or movement stroke of the blade sheath body 210, so designing a clearance space can minimize interference with the blade sheath body 210.

[0048] Optionally, in some embodiments of this application, such as Figure 3 as well as Figure 4 As shown, the distance d between the line connecting the two ends of the elastic element 223 and the hinge shaft 222 satisfies: Where l is the distance from the hinge shaft 222 to the extended end of the guide structure 221. The elastic restoring force of the elastic element 223 acts on the rotating part to form a torque, where the distance d between the line connecting the two ends of the elastic element 223 and the hinge shaft 222 is the lever arm of this torque. With the force remaining constant, the larger the lever arm, the larger the torque, thus improving the locking effect of the guide structure on the tool holder body 210. However, it should also be considered that a larger distance d is more likely to interfere with the installation or movement of the tool holder body 210; therefore, the distance d should be limited to an appropriate range.

[0049] Optionally, in some embodiments of this application, the guide structure 221 includes a first guide portion 2211, a second guide portion 2212, and a third guide portion 2213 distributed sequentially along its own extending direction. The first guide portion 2211 is close to the base 224 and hinged to the base 224 via a hinge shaft 222, thereby allowing at least one guide structure 221 to rotate relative to the base 224 of the tool holder 220. "The first guide portion is close to the base" means that, among the first guide portion 2211, the second guide portion 2212, and the third guide portion 2213, the first guide portion 2211 is closer to the base 224 than the other two. To facilitate the installation of the tool holder body 210, the guide structure 221 is rotated in the initial stage, making it easier for the sliding structure of the tool holder body 210 to assemble with the guide structure 221 to form a sliding pair.

[0050] Optionally, in some embodiments of this application, such as Figure 2 As shown, the sliding structure is a sliding groove, and the guide structure 221 is a guide rib adapted to the sliding groove. The cross-section of the third guide portion 2213 of the guide rib structure gradually decreases along its extension direction; or, as... Figure 5 As shown, the sliding structure 211 is a sliding rib, and the guide structure 221 is a guide groove adapted to the sliding rib. The grooved cross-section of the third guide portion 2213 of this guide groove structure gradually increases along its extension direction. Specifically, in Figure 2 In the middle, the cross-section of the guide rib is L-shaped. Figure 5 In the sliding structure 211, the sliding rib is inserted into the guide groove of the guide structure 221. The thickness or width of the protruding end of the sliding rib is reduced compared to its fixed end, and the protruding end has a chamfered portion. The fixed end of the sliding rib is fixed to the blade sleeve body 210, and the fixed end of the sliding rib also has a chamfered portion.

[0051] The shape and size of the third guide portion 2213 will affect whether the tool holder body 210 can be easily installed onto the tool holder seat 220. In the technical solution of this application embodiment, if the third guide portion 2213 is a "solid" structure similar to a slider and the sliding structure is a "virtual" structure similar to a groove (see...) Figure 2 If the cross-section of the third guide portion 2213 is designed to gradually decrease along its extension direction, then the tool holder body 210 is initially installed into the groove of the relatively large chamber using a relatively small slider, making it easier to install the tool holder body 210 onto the tool holder seat 220. Therefore, in the technical solution of this application embodiment, the sliding structure is more likely to cooperate with the third guide portion 2213 when installing the tool holder body 210, providing a certain degree of guidance. Correspondingly, if the third guide portion 2213 is a "virtual" structure similar to a groove and the sliding structure 211 is a "solid" structure similar to a slider (see...), Figure 5 If the grooved cross section of the third guide section 2213 is designed to gradually increase along its own extension direction, it can also enable the relatively small-sized slider to be installed into the groove of the relatively large cavity at the initial stage of installing the tool holder body 210.

[0052] Optionally, in some embodiments of this application, in the initial state of the two guide structures 221, the extending directions of the inner guide surfaces of the two second guide portions 2212 converge inwards towards each other, and the extending directions of the inner guide surfaces of the two third guide portions 2213 expand outwards towards each other. The "initial state of the two guide structures" refers to the state when the elastic element 223 is in its natural state (neither stretched nor compressed). The protruding ends of the two guide structures 221 converge inwards relative to their fixed ends, thereby further providing guidance for the installation of the tool holder body 210.

[0053] Optionally, in some embodiments of this application, such as Figure 1As shown, the tool magazine is a disc-type tool magazine. The tool magazine body 10 includes a disc body 11, a support structure 12, and a disc holder 13. The disc body 11 and the disc holder 13 are connected by the support structure 12. The support structure 12 includes multiple support ribs 121. The support ribs 121 extend vertically upward from the outer edge of the disc holder 13 and then continue to extend upward to the outer edge of the disc body 11 in an inclined upward and outward diverging manner. The support ribs 121 extend vertically upward and then extend inclined upward and outward, rather than directly extending inclined upward and outward, which saves the area occupied by the entire tool magazine body within the vertically upward extension height range. Furthermore, in some embodiments of this application, such as... Figure 1 As shown, the support rib 121 is also provided with weight reduction holes.

[0054] Optionally, in some embodiments of this application, such as Figure 1 As shown, reinforcing ribs 122 are provided on both sides of the supporting rib 121, and the reinforcing ribs 122 connect the disk body 11 and the supporting structure 12. Specifically, the reinforcing ribs 122 are located below the outer edge of the disk body 11 or below the area near the outer edge. The reinforcing ribs 122 enhance the support strength of the supporting structure 12 for the disk body 11, making the installation of the entire disk body 11 more reliable.

[0055] Optionally, in some embodiments of this application, such as Figure 1 As shown, the tool magazine also includes a mounting base 30, with a connecting plate 32 and a base plate 31 respectively provided on the top and bottom of the mounting base 30, and a second clearance space between the connecting plate 32 and the base plate 31. This clearance space accommodates a reducer 33 for driving the tool magazine body 10 to rotate, thereby further making the structure of the entire disc tool magazine more compact.

[0056] A second aspect of this application provides a CNC machine tool. The CNC machine tool includes the tool magazine described in any of the preceding embodiments. The tool magazine can be placed flat on the machine tool body, with multiple tool holders 20 distributed circumferentially along the outer edge of the tool magazine body 10, each tool holder 20 capable of storing one tool.

[0057] The above-described embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of this application. Therefore, equivalent variations made in accordance with the claims of this application are still within the scope of this application.
