Description

Technical Field

[0001] This utility model relates to the field of processing equipment technology, and in particular to a tool magazine assembly for a machine tool and the machine tool itself. Background Technology

[0002] The tool magazine is one of the core components of CNC machine tools (such as machining centers). Its main function is to provide tool storage and rapid tool changing for automated machining. It can also work with an Automatic Tool Changer (ATC) to achieve unattended tool changing.

[0003] However, when the machine tool spindle needs to perform the next machining operation, the tool needs to be changed. Existing straight-line tool magazines need to be pushed from the back of the worktable to the front of the worktable before changing tools with the spindle (such as the machine tool in patent publication number CN212946729 U). This will cause some tools in the tool magazine that do not need to be changed to be pushed to the front of the worktable. These tools are no longer protected and are very likely to be contaminated by cutting fluid and chips, affecting the tool life.

[0004] Therefore, how to remove only the tools for the next process from the tool magazine during tool changing, while keeping the tools that do not need to be replaced in the magazine, thereby reducing the possibility of contamination of the tools that do not need to be replaced and improving the life of the tool magazine, is an urgent problem to be solved.

[0035] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0036] In the description of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0037] 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 technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0038] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] To provide a clearer and more accurate understanding of the present invention, a detailed description will now be provided in conjunction with the accompanying drawings. The accompanying drawings illustrate examples of embodiments of the present invention, wherein the same reference numerals denote the same elements. It is to be understood that the scale shown in the accompanying drawings is not the actual scale of the present invention, but is for illustrative purposes only and is not a drawing based on the original dimensions.

[0040] The primary function of a tool magazine is to provide tool storage and quick tool changing capabilities for automated machining. When the machine tool spindle needs to proceed to the next machining operation, the tool needs to be changed. Existing linear tool magazines require all tools to be pushed from the back of the worktable to the front before changing tools with the spindle. This results in some tools that do not need to be changed being pushed to the front of the worktable. These tools are unprotected and are highly susceptible to contamination by cutting fluid and chips, affecting their lifespan.

[0041] To reduce the risk of contamination of tools that do not need to be replaced in the tool magazine during tool changing and to improve the lifespan of the tool magazine, this embodiment provides a tool magazine assembly for a machine tool, including a support frame 100, a tool magazine 200 disposed on the support frame 100, and a tool retrieval device 300.

[0042] The support frame 100 provides support for structural components mounted on it. In this embodiment, the support frame 100 is used to mount the tool magazine 200 and the tool retrieval device 300. The support frame 100 has a three-dimensional structure, and the tool magazine 200 is rotatably supported on the support frame 100. For example, the tool magazine 200 is located at the top of the support frame 100. The tool retrieval device 300 is mounted on the support frame 100, and a portion of the tool retrieval device 300's vertical projection is located within the tool magazine 200. This saves space and improves the space utilization of the machine tool. Furthermore, the proximity of the tool retrieval device 300 to the tool magazine 200 facilitates cooperation between the tool retrieval device 300 and the tool magazine 200 for tool changing. The vertical direction is... Figure 1 The second direction in the middle is the horizontal direction. Figure 1 The first direction in the middle is that the vertical and horizontal directions are perpendicular to each other.

[0043] Please refer to Figure 1In order to enable multi-channel processing, the number of tool magazines 200 is at least two, and the number of tool retrieval devices 300 corresponds to the number of tool magazines 200. Multiple sets of tool magazines 200 and tool retrieval devices 300 are set on a support frame 100, which can increase the number of workpieces processed by the machine tool per unit time, thereby increasing the machine tool's productivity and saving the number of support frames 100.

[0044] Please refer to Figure 1 The following describes the operational coordination between the tool magazine 200 and the tool retrieval device 300. The tool magazine 200 is equipped with grippers 210 for holding the tool D and a tool changing port H for tool changing. The grippers 210 can move to the tool changing port H. The grippers 210 are used to hold the tool D. The tool changing port H is the position of the tool magazine 200 along the first direction and close to the tool retrieval device 300. When one of the grippers 210 in the tool magazine 200 rotates to the tool changing port H, the tool retrieval device 300 engages with the grippers 210 located at the tool changing port H to perform a tool change. For example, when there is no tool D on the grippers 210 at the tool changing port H, the tool retrieval device 300 can put the already machined tool D back onto the grippers 210 located at the tool changing port H. When the grippers 210 at the tool changing port H holds the tool D for the next machining operation, the tool retrieval device 300 can unload the tool D for the next machining operation from the grippers 210 at the tool changing port H.

[0045] To increase the number of tools D stored in the tool magazine 200, please refer to... Figure 2 and 3 The tool magazine 200 also includes a rotary chain 220. The rotation axis of the rotary chain 220 is in a second direction. It can be understood that a fixing frame for fixing the grippers 210 is provided at the top of the rotary chain 220. The fixing frame is mounted on the rotary chain 220, and the extension line of the center of gravity of the fixing frame falls on the rotary chain 220, thereby making the grippers 210 more stable as they rotate with the rotary chain 220 after being installed on the fixing frame. In this embodiment, there are two rotary chains 220, which are stacked vertically to provide better rotational force for the multiple grippers 210.

[0046] For better vertical mounting of the tool magazine 200 onto the support frame 100, please refer to... Figure 3 The support frame 100 includes a base plate 110, a support plate 120 disposed on the base plate 110, and a mounting plate 130 disposed on the top of the support plate 120. The base plate 110, the support plate 120 and the mounting plate 130 increase in height along the vertical direction, thereby better installing the tool magazine 200 and the tool retrieval device 300.

[0047] To minimize the material used in the support bracket 100 and reduce the weight of the tool magazine assembly, please refer to... Figure 3The 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. One end of the support plate 120 extends 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.

[0048] The specific structure of the support plate 120 is described below. Please refer to [link / reference]. Figure 3 The base plate 110, support plate 120, and mounting plate 130 increase in height sequentially along the second direction. 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 cross-sectional area of ​​the first support leg 121 along the horizontal direction is larger than that of the second support leg 123 along the horizontal direction, thereby ensuring the stability of the structural components installed 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 extends out from one side of the base plate 110. The mounting plate 130 is installed on the suspended section 1222 via the second support leg 123, thereby saving the length of the base plate 110 along the vertical direction located on the suspended section 1222 and minimizing the weight of the tool magazine assembly.

[0049] To reduce the length of the base plate 110 and thus the weight of the support frame 100, the two ends of the first support leg 121 are respectively fixed to the base plate 110 and the mounting section 1221. By setting the suspended section 1222, the length of the base plate 110 along the first direction can be reduced, saving material of the base plate 110. Furthermore, the position of the support frame 100 along the second direction corresponding to the suspended section 1222 can also be set to be hollow, thereby saving volume and material of the support frame 100.

[0050] To make the structure between the support frame 100 and the tool magazine 200 more compact, please refer to... Figure 3 The mounting plate 130 includes an extended end 131 suspended above the gripper 210. The bottom of the extended end 131 is provided with a relief groove 1311 to avoid the rotation of the gripper 210. This allows the mounting plate 130 to be suspended on the gripper 210 as much as possible, so that the tool clamping mechanism 310 is as close as possible to the gripper 210 when the mounting plate 130 is installed in the tool magazine 200.

[0051] To ensure the stability of the support frame 100, please refer to... Figure 3The suspended section 1222 causes an imbalance in weight on both sides of the support frame 100 along the first direction, leading to a tendency for the suspended section 1222 to sag. The support frame 100 also includes a balance bracket 140, which spans above the base plate 110 and the mounting section 1221. The balance bracket 140 is located within the slewing chain 220. The balance bracket 140 is positioned away from the suspended section 1222, thus acting as a reinforcing rib. This allows the side of the support plate 120 furthest from the suspended section 1222 to be pressed down by the balance bracket 140, counteracting the sag of the suspended section 1222 and ensuring the stability of the structural components mounted on the support frame 100.

[0052] Please refer to Figure 2 and 3 Since the weight increases after the multiple grippers 210 on the outer periphery of the rotary chain 220 clamp the tool D, in order to enable the rotary chain 220 on the tool magazine 200 to more stably drive the grippers 210 clamping the tool D, the balance bracket 140 includes a cover plate 141 and two support legs supported under the cover plate 141. The two support legs are respectively connected to the surface of the base plate 110 and away from the first support leg 121, and the surface of the middle plate 122 and away from the second support leg 123. The cover plate 141 is used to limit the movement trajectory of the top of the grippers 210. Specifically, the cover plate 141 is fixedly mounted on the support frame 100, and the cover plate 141 is located on the multiple grippers 210; the bottom of the cover plate 141 is provided with a guide groove corresponding to the rotation trajectory of the grippers 210. For example, the guide groove is shaped like half a racetrack, which includes two spaced straight tracks and a curved track connected to one side of the two straight tracks. Each of the grippers 210 has a guide body 211 extending into a guide groove at its top. The guide body 211 is rotatable vertically relative to the gripper 210. By providing a rotatable guide body 211, the sliding connection between the gripper 210 and the guide groove is changed to a rolling connection, which reduces the friction between the gripper 210 and the guide groove, making the guide body 211 of the gripper 210 slide more smoothly in the guide groove.

[0053] Please refer to Figure 3 The tool magazine 200 also includes a drive sprocket 230 and a driven sprocket 240; the drive sprocket 230 is rotatably supported on the base plate 110, and the driven sprocket 240 is rotatably supported on the support plate 120. Specifically, the driven sprocket 240 is rotatably supported on the suspended section 1222. The rotary chain 220 is sleeved on the outer periphery of the drive sprocket 230 and the driven sprocket 240. 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 refer to Figure 3 In order to adjust the tension of the rotary chain 220, the driven sprocket 240 has a seat 241, which is detachably connected to the intermediate plate 122 by fasteners. The seat 241 has a fixed state and an open state relative to the intermediate plate 122. The tool magazine 200 also includes an adjustment mechanism 250.

[0055] The following describes the specific structure of the adjustment mechanism 250. Please refer to [link / reference]. Figure 3 The adjustment mechanism 250 is connected to the support frame 100 and the seat 241 and is used to adjust the tension of the rotary chain 220. The adjustment mechanism 250 is disposed at least on one side of the seat 241 and between the intermediate plate 122 along a first direction. The adjustment mechanism 250 includes an adjustment member 251, which is movably connected to the intermediate plate 122 and abuts against the seat 241. In the active state of the seat 241, the adjustment member 251 is used to adjust the position of the seat 241 relative to the intermediate plate 122.

[0056] Adjustment component 251 can have two structures: block-shaped or rod-shaped, which can be adjusted according to the actual situation. Please refer to [reference needed]. Figure 3 The adjusting member 251 includes a first pushing body 2511 and a second pushing body 2512, which are respectively disposed on both sides of the seat 241 and between the intermediate plate 122 in the front-back direction. The first pushing body 2511 has an inclined pushing block, and the intermediate 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 241 relative to the intermediate plate 122 in the front-back direction. It can be understood that the side of the inclined pushing block near the balance bracket 140 is provided with an inclined surface through a recess, and the cross-sectional area of ​​the top of the inclined pushing block is larger than the cross-sectional area of ​​the bottom of the inclined pushing block. When the inclined pushing block moves vertically towards the bottom of the inclined guide groove 1223, it will push the seat 241 to move away from the balance bracket 140 in the first direction.

[0057] The following describes the adjustment method when the adjusting component 251 has a rod-shaped structure. Please refer to [link / reference]. Figure 3The second pushing body 2512 has a rotating bolt, and the intermediate plate 122 has a protruding mounting body 1224. The rotating bolt is rotatably mounted on the mounting body 1224 and threadedly engaged with it. Adjusting the depth of the rotating bolt's insertion into the mounting body 1224 adjusts the position of the seat 241 relative to the intermediate plate 122 in the front-to-back direction. Each rotation of the rotating bolt pushes the seat 241 to move one thread pitch closer to the balance bracket 140, resulting in higher adjustment precision. To ensure the rotating bolt adjusts along a straight line, two rotating bolts can be used. The mounting body 1224 has two threaded holes, allowing both rotating bolts to rotate simultaneously within the mounting body 1224, preventing misalignment when a single rotating bolt rotates.

[0058] Please refer to Figure 1 and 2 The tool retrieving device 300 is an auxiliary device in the tool magazine 200 and spindle tool changing process. The tool retrieving device 300 is used to clamp an external tool D onto the jaws 210 of the tool magazine 200, or to remove the tool D from the jaws 210 of the tool magazine 200. The tool retrieving device 300 moves along a first direction, with a travel distance of at least two jaws 210. The tool retrieving 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 along a first direction and a second direction.

[0059] Please refer to Figure 2 and 4The tool clamping mechanism 310 is provided with a bayonet T for clamping the tool D. The bayonet T is positioned to match 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. The connecting seat 323 is movably disposed above the tool magazine 200. Specifically, the connecting seat 323 is movably disposed on the mounting plate 130 above the tool magazine 200. The first driving member 321 is supported on the mounting plate 130 and is disposed on the support frame 100 along a first direction. The projection of the first driving member 321 along a second direction is located within the rotary chain 220. Most of the projection of the mounting plate 130 along the second direction is located within the rotary chain 220. The tool retrieval device 300 can utilize the existing space within the rotary chain 220, reducing the space occupied by the tool magazine assembly and also reducing the distance between the tool retrieval device 300 and the gripper 210 located at the tool change port H. This facilitates the movement of the tool clamping mechanism 310 from within the rotary chain 220 along the first direction toward the tool change port H. The tool clamping mechanism 310 can reciprocate along the first direction from the tool change port H to the outside of the rotary chain 220 via the first drive member 321. This facilitates the tool clamping mechanism 310 pushing the tool D on the gripper 210 along the first direction and pushing the tool D onto the gripper 210 along the first direction, thereby improving the space utilization of the machine tool and reducing its size.

[0060] Please refer to Figure 3 The connecting seat 323 is movably disposed on the mounting plate 130 above the tool magazine 200. 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. Under the push of the first driving member 321, the tool clamping mechanism 310 can reciprocate along the first direction from above the clamping jaw 210 to the outside of the clamping jaw 210.

[0061] Please refer to Figure 4The first driving member 321 is used to drive the connecting seat 323 to move relative to the tool magazine 200 along a first direction. The tool clamping mechanism 310 is movably disposed 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. The second driving member 322 is disposed on the connecting seat 323 along the second direction. The height of the bottom of the second driving member 322 is higher than the height of the clamp 210. The second direction is the tool D loading and unloading direction of the clamp 210 at the tool change port H. The first direction and the second direction form a preset angle. In this embodiment, the first direction and the second direction are perpendicular.

[0062] Please refer to Figure 2 and 4 To facilitate the mounting of the first driving component 321 onto the support frame 100, specifically by mounting the first driving component 321 onto the mounting plate 130 on the support frame 100, the moving mechanism 320 further includes a fixing plate 324 and a fixing block 325. The fixing plate 324 is used to mount the first driving component 321 onto the support frame 100. The fixing plate 324 is fixed to the support frame 100, and the fixed end of the first driving component 321 is fixed to the fixing plate 324. The fixing plate 324 may include a vertical plate and a horizontal plate, with the vertical plate perpendicularly connected to the horizontal plate and the fixed end of the first driving component 321 connected to it. The vertical plate also has a through hole for the telescopic end to move. The horizontal plate is detachably connected to the mounting plate 130, and either the horizontal plate or the mounting plate 130 has a slotted hole to facilitate adjustment of the position of the horizontal plate and the mounting plate 130 along the first direction.

[0063] Please refer to Figure 4 In order to transmit the power of the first driving member 321 to the connecting seat 323 and to ensure that the first driving member 321 and the second driving member 322 are located in the same plane along the first direction, the fixing block 325 is fixedly connected to the connecting seat 323, and the back of the fixing block 325 is connected to the connecting seat 323. The second driving member 322 is fixedly connected to the connecting seat 323, and the back of the second driving member 322 is fixedly connected to the connecting seat 323.

[0064] The tool clamping mechanism 310 is connected to the second driving member 322 via the transmission member 326. The first driving member 321, the second driving member 322, and the tool clamping mechanism 310 are arranged sequentially along a first direction. For example, the first driving member 321, the second driving member 322, and the tool clamping mechanism 310 are arranged side by side along the first direction. The second driving member 322 is used to drive the transmission member 326 and the tool clamping mechanism 310 to move along a second direction. When the tool clamping mechanism 310 moves along the second direction, it is used to engage or disengage from the tool holder of the tool D.

[0065] Please refer to Figure 4 The specific structure of the transmission component 326 is described below. The transmission component 326 includes a bending connecting block 3261 and a mounting block 3262; the second driving component 322 is arranged along a second direction, and the lifting part of the second driving component 322 is located at the top. The top of the fixing part of the second driving component 322 is aligned with the top of the connecting seat 323. The transmission component 326 is located at the top and side of the second driving component 322. The bending connecting block 3261 is connected to the lifting part of the second driving component 322, and the mounting block 3262 is connected to the bending connecting block 3261. The mounting block 3262 and the second driving component 322 are arranged side by side along a first direction. The clamping mechanism 310 is connected to the mounting block 3262, and the clamping mechanism 310 and the mounting block 3262 are arranged side by side along the first direction. This ensures that when the second driving member 322 is in the retracted state, the first driving member 321, the fixing block 325, the second driving member 322, the mounting block 3262, and the clamping mechanism 310 are all arranged side by side along the first direction.

[0066] Please refer to Figure 4 To guide the connecting seat 323, the second driving member 322, and the clamping mechanism 310 to move along a first direction, the moving mechanism 320 further includes a first guide rail D1 and a first slider H1. The first guide rail D1 is disposed on the support frame 100, and the first slider H1 is fixed to the fixing block 325 or the connecting seat 323. The first guide rail D1 and the first slider H1 are slidably engaged to provide guidance for the connecting seat 323 to move along the first direction and prevent deviation when the first driving member 321 is driven. And / or,

[0067] To guide the clamping mechanism 310 to move in the second direction, the moving mechanism 320 further includes a second guide rail D2 and a second slider H2. The second guide rail D2 is disposed on the connecting seat 323, and the second slider H2 is disposed on the bent connecting block 3261 or the mounting block 3262. The second guide rail D2 and the second slider H2 are slidably engaged to provide guidance for the clamping mechanism 310 to move in the second direction, thereby preventing deviation when the second driving member 322 is driven.

[0068] Please refer to Figure 4 To prevent the tool D from carrying some cutting fluid and chips and thus contaminating the tool magazine assembly during the process of the tool clamping mechanism 310 pushing the tool D on the clamp 210 in the first direction and pushing the tool D onto the clamp 210 in the first direction, the tool retrieval device 300 also includes an air supply component 400. The air supply component 400 is disposed on the tool clamping mechanism 310 and has an air supply port Q. The air supply direction of the air supply port Q is towards the jaw T of the tool clamping mechanism 310. It can be understood that the air supply component 400 has an air supply channel inside, and the air supply channel has an air supply port and an air outlet. The tool retrieval device 300 also includes an air supply pipe. The air outlet of the air supply component 400 is connected to the air supply pipe. The end of the air supply pipe is the air supply port Q, and the angle of the air supply pipe relative to the air supply component 400 can be adjusted to adjust the orientation of the air supply port Q, which is convenient for adjustment when the air supply port Q is offset.

[0069] The aforementioned tool magazine assembly includes a support frame 100, a tool magazine 200 mounted on the support frame 100, and a tool retrieval device 300. The tool magazine 200 is equipped with multiple grippers 210 and a tool changing port H for tool changing. The multiple grippers 210 are movable to the tool changing port H. The tool retrieval device 300 includes a tool clamping mechanism 310 and a moving mechanism 320. The tool clamping mechanism 310 is provided with a bayonet T for clamping a tool D, and 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... A connecting seat 323 is movably disposed above the tool magazine 200. A first driving member 321 is used to drive the connecting seat 323 to move relative to the tool magazine 200 in a first direction. A tool clamping mechanism 310 is movably disposed on the connecting seat 323. A second driving member 322 is used to drive the tool clamping mechanism 310 to move relative to the connecting seat 323 in a second direction. The second direction is the tool loading and unloading direction of the gripper 210 at the tool changing port H. The first direction and the second direction form a preset angle.

[0070] The moving mechanism 320 drives the tool clamping mechanism 310 to move, thereby unloading the tool D to be replaced from the tool magazine 200. Then, the tool is replaced with the spindle through other structural components (such as a robot or other movable tool changer arms). Compared with the existing scheme of pushing out the entire straight-line tool magazine, during tool replacement, the tool D that does not need to be replaced is kept in the tool magazine 200 and will not move under the spindle. This avoids the cutting fluid from easily contaminating the tool D that does not need to be replaced, protects the tool D that does not need to be replaced, and improves the service life of the tool magazine 200.

[0071] On the other hand, this embodiment also provides a machine tool, including a base, a column mounted on the base, and a spindle mounted on the column. The machine tool also includes the aforementioned tool magazine assembly. The support frame 100 of the tool magazine assembly is fixedly mounted on the base or the column, and the tool retrieval device 300 cooperates with the spindle to perform tool changing. Since this machine tool includes the aforementioned tool magazine assembly, it also has the corresponding technical effects of the tool magazine assembly, which will not be elaborated further here.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.

[0073] The above-listed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
