[0002] The tool magazine is a core component of CNC machine tools (such as machining centers). Its main function is to provide tool storage and rapid tool change capabilities for automated machining. It can also be used in conjunction with an automatic tool changer (ATC) to achieve unmanned tool changes.

[0003] However, when the spindle of the machine tool needs to perform the next processing operation, the tool needs to be replaced. The existing straight-row tool magazine needs to be pushed from the back of the workbench to the front of the workbench, and then the tool is replaced with the spindle (such as the machine tool in patent announcement No. CN212946729 U). This will cause some tools in the tool magazine that do not need to be replaced to be pushed to the front of the workbench. These tools lose their protection and are likely to be contaminated by cutting fluid and chips, which will affect the life of the tool.

[0004] Therefore, how to only take out the tools that need to be replaced from the tool magazine during the tool change process, reduce the number of tools taken out from the tool magazine, and keep the tools that do not need to be replaced in the tool magazine protected by the tool magazine cover to increase the life of the tool magazine is an urgent problem to be solved.

[0038] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION

[0039] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0040] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0041] In the present invention, unless otherwise specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0042] To provide a clearer and more accurate understanding of the present invention, the present invention will now be described in detail with reference to the accompanying drawings. The accompanying drawings illustrate exemplary embodiments of the present invention, with like reference numerals representing like elements. It should be understood that the scales shown in the accompanying drawings are not those of actual implementations of the present invention. These scales are for illustrative purposes only and are not drawn to scale.

[0043] The primary function of a tool magazine is to provide tool storage and rapid tool change capabilities for automated machining. When a machine tool's spindle needs to proceed to the next machining process, the tool must be replaced. Existing inline tool magazines require all tools to be pushed from behind the worktable to the front before the spindle can be used for tool change. This can cause some tools in the magazine that don't need to be replaced to be pushed to the front of the worktable. These tools, unprotected, are at high risk of contamination from cutting fluid and chips, shortening their lifespan.

[0044] Please see Figure 1 and 2 In order to reduce the risk of contamination of tools that do not need to be replaced in the tool magazine during the tool changing process and to increase the life of the tool magazine, on the one hand, this embodiment provides a tool magazine assembly for a machine tool, including a support frame 100, a chain tool magazine 200 arranged on the support frame 100, and the tool magazine assembly of the machine tool also includes a tool picking device 300.

[0045] The support frame 100 is used to provide support for the structural parts installed on the support frame 100. In this embodiment, the support frame 100 is used to install the chain tool magazine 200 and the tool taking device 300. The support frame 100 is a three-dimensional structure, and the chain tool magazine 200 is rotatably supported on the support frame 100. For example, the chain tool magazine 200 is arranged on the top of the support frame 100. The tool taking device 300 is arranged on the support frame 100 and part of the structure of the tool taking device 300 is located in the chain tool magazine 200 along the vertical projection. On the one hand, it saves space and improves the space utilization rate of the machine tool. On the other hand, the tool taking device 300 is close to the chain tool magazine 200, which facilitates the cooperation between the tool taking device 300 and the chain tool magazine 200 to change tools. Among them, the vertical direction is Figure 1 The second direction in the horizontal direction is Figure 1 In the first direction, the vertical direction and the horizontal direction are perpendicular to each other.

[0046] Please see Figure 1In order to be able to perform multi-channel processing, the number of the chain tool magazines 200 is at least two, and the number of the tool-picking devices 300 corresponds to the number of the chain tool magazines 200. Multiple sets of chain tool magazines 200 and tool-picking devices 300 are set on a support frame 100, so as to increase the number of workpieces processed by the machine tool per unit time, thereby improving the production capacity of the machine tool.

[0047] The chain tool magazine 200 is provided with a plurality of clamps 210 and a tool changing port H for tool changing. The plurality of clamps 210 can be moved to the tool changing port H; the clamps 210 are used to clamp the tool D. The tool changing port H is the position of the tool magazine along the first direction and is close to the tool picking device 300. When a clamp 210 in the chain tool magazine 200 rotates to the tool changing port H, the tool picking device 300 cooperates with the clamp 210 located at the tool changing port H to change the tool.

[0048] Please see Figure 2 and 3 The chain tool magazine 200 further includes a slewing chain 220, a driving sprocket 230, and a driven sprocket 240. The axis of rotation of the slewing chain 220 is in the second direction. It is understood that a fixing bracket for securing the clamping jaws 210 is provided at the top of the slewing chain 220. The fixing bracket is mounted on the slewing chain 220, and the extension line of the center of gravity of the fixing bracket falls on the slewing chain 220. This ensures that the clamping jaws 210 are more stable when mounted on the fixing bracket as they rotate with the slewing chain 220. In this embodiment, there are two slewing chains 220, which are stacked vertically, thereby providing better rotational force for the multiple clamping jaws 210.

[0049] Please see Figure 3 The support frame 100 includes a base plate 110, a support plate 120 arranged on the base plate 110, and a mounting plate 130 arranged on the top of the support plate 120. The chain tool magazine 200 is located between the base plate 110 and the mounting plate 130; the projection of the support plate 120 along the second direction coincides with the projection of the base plate 110 along the second direction, and one end of the support plate 120 cantilevers out from one side of the base plate 110. The material at the bottom of the base plate 110 at one end of the support plate 120 can be saved, and the length of the base plate 110 along the first direction can be reduced, while ensuring that the base plate 110 and the support plate 120 jointly support the mounting plate 130.

[0050] Please see Figure 3The heights of the bottom plate 110, support plate 120, and mounting plate 130 increase in sequence along the second direction. The specific structure of the support plate 120 is described below. The support plate 120 includes a first support leg 121, an intermediate plate 122 disposed on the first support leg 121, and a second support leg 123 disposed on the intermediate plate 122. The horizontal cross-sectional area of ​​the first support leg 121 is greater than the horizontal cross-sectional area of ​​the second support leg 123, thereby ensuring the stability of the structural components mounted on the support plate 120 and mounting plate 130. The mounting plate 130 is supported on the second support leg 123. The intermediate plate 122 includes a mounting section 1221 that overlaps with the base plate 110 along the first direction and a suspended section 1222 that cantilevers out from one side of the base plate 110. The mounting plate 130 is mounted on the suspended section 1222 via the second support leg 123. The first support leg 121 is fixed at both ends to the base plate 110 and the mounting section 1221, respectively. The driven sprocket 240 is rotatably supported on the suspended section 1222. The provision of the suspended section 1222 reduces the length of the base plate 110 along the first direction, saving material for the base plate 110. Furthermore, the portion of the support frame 100 corresponding to the suspended section 1222 along the second direction can also be hollowed out, thereby saving volume and material of the support frame 100.

[0051] Please see Figure 3 The suspended section 1222 may cause a weight imbalance on both sides of the support frame 100 along the first direction, and the suspended section 1222 may have a tendency to fall. To ensure the stability of the support frame 100, the support frame 100 further includes a balancing bracket 140. The balancing bracket 140 is arranged across the bottom plate 110 and the mounting section 1221 and is disposed within the slewing chain 220. The balancing bracket 140 is disposed away from the suspended section 1222.

[0052] Please see Figure 2 and 3Since the multiple clamping jaws 210 on the outer periphery of the rotating chain 220 increase in weight after clamping the tool D, in order to ensure that the rotating chain 220 on the chain tool magazine 200 can more stably drive the clamping jaws 210 with the tool D to rotate, the balancing bracket 140 includes a cover plate 141 and two support legs supported below the cover plate 141. The two support legs are respectively connected to the surface of the base plate 110 at a position away from the first support leg 121 and to the surface of the intermediate plate 122 at a position away from the second support leg 123. The cover plate 141 is used to limit the movement trajectory of the top of the clamping jaws 210. Specifically, the cover plate 141 is fixed to the support frame 100 and is located on the multiple clamping jaws 210. The bottom of the cover plate 141 is provided with a guide groove corresponding to the rotation trajectory of the clamping jaws 210. For example, the guide groove is shaped like a half-racetrack, which includes two spaced-apart straight paths and a curved path connected to one side of the two straight paths. A guide body 211 extending into the guide groove is provided at the top of each clamping jaw 210, and the guide body 211 can be rotated vertically relative to the clamping jaw 210; by providing a rotatable guide body 211, the sliding connection between the clamping jaw 210 and the guide groove is changed into a rolling connection, thereby reducing the friction between the clamping jaw 210 and the guide groove, and making the guide body 211 of the clamping jaw 210 smoother in the guide groove.

[0053] Please see Figure 3 The driving sprocket 230 can be rotatably supported on the base plate 110, the driven sprocket 240 can be rotatably supported on the support plate 120, the rotary chain 220 is sleeved on the outer periphery of the driving sprocket 230 and the driven sprocket 240, and the mounting plate 130 is located above the rotary chain 220; the projection of the mounting plate 130 along the second direction is located inside the rotary chain 220, making full use of the space inside the rotary chain 220.

[0054] Please see Figure 3 In order to adjust the tension of the rotating chain 220, the driven sprocket 240 has a seat body 241, and the seat body 241 is detachably connected to the intermediate plate 122 through fasteners. The seat body 241 has a fastened state and an active state relative to the intermediate plate 122; the chain tool magazine 200 also includes an adjustment mechanism 250.

[0055] Please see Figure 3 The adjustment mechanism 250 is arranged at least between one side of the seat body 241 and the middle plate 122 along the first direction. The adjustment mechanism 250 includes an adjustment member 251. The adjustment member 251 is movably connected to the middle plate 122 and abuts against the seat body 241. When the seat body 241 is in an active state, the adjustment member 251 is used to adjust the position of the seat body 241 relative to the middle plate 122.

[0056] The adjusting member 251 includes a first pushing body 2511 and a second pushing body 2512 . The first pushing body 2511 and the second pushing body 2512 are respectively disposed on both sides of the base 241 and between the middle plate 122 along the front-to-back direction.

[0057] The first pushing body 2511 has an inclined pushing block, and the middle plate 122 is recessed with an inclined guide groove 1223 that cooperates with the inclined pushing block. The inclined pushing block changes the contact area with the inclined surface of the inclined guide groove 1223 by moving up and down, thereby adjusting the position of the seat body 241 relative to the middle plate 122 along the front-to-back direction.

[0058] The second pushing body 2512 has a rotating bolt, and a mounting body 1224 is protruded on the middle plate 122; the rotating bolt can be rotatably set on the mounting body 1224 and is threadedly engaged with the mounting body 1224. The rotating bolt adjusts the depth of being screwed into the mounting body 1224 to adjust the position of the seat body 241 relative to the middle plate 122 along the front-to-back direction.

[0059] Please see Figure 1 and 2 The tool removal device 300 is an auxiliary device in the tool change step between the tool magazine and the spindle of the machine tool. The tool removal device 300 is used to clamp an external tool D to the clamping jaws 210 of the chain tool magazine 200, or to remove the tool D from the clamping jaws 210 of the chain tool magazine 200. The tool removal device 300 moves along a first direction, and the movement stroke is at least the length of two clamping jaws 210. The tool removal device 300 includes a tool clamping mechanism 310 and a moving mechanism 320. The tool clamping mechanism 310 cooperates with the tool D, and the moving mechanism 320 drives the tool clamping mechanism 310 to move in the first direction and the second direction.

[0060] Please see Figure 2 and 4The tool clamping mechanism 310 is provided with a bayonet T for clamping a tool D, and the position of the bayonet T is matched with the tool changing port H. The moving mechanism 320 includes a first driving member 321, a second driving member 322 and a connecting seat 323, and the connecting seat 323 is movably arranged above the chain tool magazine 200. The first driving member 321 is supported on the mounting plate 130. Since most of the projection of the mounting plate 130 along the second direction is located in the rotary chain 220, the tool taking device 300 can utilize the existing space in the rotary chain 220 to reduce the occupied space of the tool magazine assembly, and also reduce the distance between the tool taking device 300 and the clamping claw 210 at the tool changing port H, so as to facilitate the tool clamping mechanism 310 to move from the rotary chain 220 along the first direction toward the tool changing port H, and facilitate the tool clamping mechanism 310 to push the tool D on the clamping claw 210 along the first direction and push the tool D onto the clamping claw 210 along the first direction, thereby improving the space utilization of the machine tool and reducing the volume of the machine tool.

[0061] Please see Figure 3 The connecting seat 323 is movably arranged on the mounting plate 130 above the chain tool magazine 200, and the first driving member 321 drives the connecting seat 323, the second driving member 322 and the tool clamping mechanism 310 to move on the mounting plate 130 along the first direction; the tool clamping mechanism 310 reciprocates along the first direction from the tool changing port H to the outside of the rotary chain 220 through the first driving member 321.

[0062] Please see Figure 3 and 4 The first driving member 321 is used to drive the connecting seat 323 to move relative to the chain tool magazine 200 along a first direction, and the tool clamping mechanism 310 is movably arranged on the connecting seat 323. The second driving member 322 is used to drive the tool clamping mechanism 310 to move relative to the connecting seat 323 along a second direction, wherein the second direction is the loading and unloading direction of the tool D of the clamping jaw 210 at the tool changing port H, and the first direction and the second direction are at a preset angle. In this embodiment, the first direction is perpendicular to the second direction.

[0063] Please see Figure 2 and 4In order to facilitate the installation of the first driving member 321 on the support frame 100, specifically on the mounting plate 130 on the support frame 100, the moving mechanism 320 also includes a fixing plate 324 and a fixing block 325. The fixing plate 324 is used to install the first driving member 321 on the support frame 100. The fixing plate 324 is fixed to the support frame 100, and the fixed end of the first driving member 321 is fixed to the fixing plate 324. The fixing plate 324 may include a vertical plate and a horizontal plate. The vertical plate is vertically connected to the horizontal plate, and the vertical plate is connected to the fixed end of the first driving member 321.
