Abstract
Description
Technical Field
[0001] This utility model relates to a vertical tool magazine and belongs to the field of automated machining equipment. Background Technology
[0002] CNC machining equipment integrates multiple machining processes on a single machine tool. When switching between processes, different tools often need to be changed. Therefore, the tool magazine becomes an important component of machining equipment. Different types of tool magazines are often matched with different machining equipment. Among them, the main types of tool magazines used with existing machining equipment are disc tool magazines, chain tool magazines, and D-type tool magazines.
[0003] Currently, for equipment with multiple spindles machining simultaneously, a tool magazine is often required for each spindle for tool changing. However, traditional disc tool magazines are limited by the spindle diameter and the distance between adjacent spindles, resulting in a small tool capacity that is difficult to expand. Therefore, for machining equipment requiring a large number of tools, traditional disc tool magazines are insufficient. The simpler D-type tool magazine has even smaller tool capacity and tool changing speed than disc tool magazines, making it suitable only for small-batch production and unable to meet the complex machining needs of large-batch production and multi-spindle machining requiring multiple tool changes. Using a chain tool magazine to increase tool capacity would increase manufacturing costs and machine tool footprint. Utility Model Content

For example, without departing from the scope of this disclosure, a first element may also be referred to as a second element, and similarly, a second element may also be referred to as a first element.
[0037] See Figures 1 to 5The vertical tool magazine of this utility model is applied to a machining equipment. The machining equipment includes a bed 500, a worktable 510 and a gantry 520 mounted on the bed 500. A machining assembly 530 is mounted on the gantry 520, which includes a tool magazine assembly 100, a tool-retrieving robot 200, and a transfer device 300. The tool magazine assembly 100 includes a tool magazine support 110 and multiple tools 400. The tool magazine support 110 is located on the side of the gantry 520 away from the machining assembly 530, and the multiple tools 400 are mounted on the tool magazine support 110 and mounted on the same... In the vertical plane; the tool retrieval robot 200 is located on the side of the tool magazine assembly 100 away from the gantry 520, and the tool retrieval robot 200 includes a tool retrieval sleeve for gripping the tool 400; it is located below the machining assembly 530 and the tool magazine assembly 100, and the intermediate mounting device includes a transfer base plate 310 and a transfer assembly 320 for placing the tool 400; the transfer assembly 320 is mounted on the transfer base plate 310; wherein, the bed 500 is provided with a horizontal guide rail 540, and the worktable 510 and the transfer base plate 310 are independently movable and mounted on the horizontal guide rail 540.
[0038] See Figure 1 The vertical tool magazine of this utility model can be applied to machining equipment. The two columns of the gantry frame 520 of the machining equipment are respectively located on the left and right sides of the bed 500. Two horizontal guide rails 540 are located in the middle of the bed 500 and between the two columns. The worktable 510 and the transfer base plate 310 are independently movable back and forth on the horizontal guide rails 540, with the worktable 510 located in front of the transfer base plate 310. The two ends of the crossbeam of the gantry frame 520 are connected to the two columns respectively. A machining component 530 is located on the front side of the crossbeam, and a tool magazine component 100 and a tool-retrieving robot 200 are located on the rear side of the crossbeam.
[0039] When the machining component 530 is machining the workpiece on the worktable 510, the transfer device 300 moves separately to the tool preparation position below the tool-retrieving robot 200. The tool-retrieving robot 200 places the tool 400 from the tool magazine component 100 onto the transfer component 320 through the tool sheath, thus completing the tool preparation of the transfer device 300. After the workpiece is finished, the worktable 510 moves forward and the transfer device 300 also moves forward, so that the transfer component 320 reaches the tool changing position below the machining component 530. After the machining component 530 changes to the tool 400 on the transfer component 320, the transfer device 300 moves backward, and the worktable 510 also moves backward back to the rear of the machining component 530 to carry out the next machining process. Furthermore, since the worktable 510 and the transfer device 300 can move independently, the movement of the transfer device 300 is not limited by the movement of the worktable 510. For example, after the transfer device 300 obtains the next process tool 400 under the tool-retrieving robot arm 200, the transfer device 300 can first move forward from the tool preparation position to the waiting position. After the worktable 510 has finished moving forward, the transfer device 300 then moves forward to under the machining assembly 530, thereby shortening the tool change time. It is understood that the waiting position is set between the tool preparation position and the tool change position.
[0040] In some embodiments, see Figure 1 and Figure 3 The tool magazine support 110 is a roughly square frame 111, which is vertically mounted on the side of the gantry 520. Multiple crossbars 112 are connected to the center of the frame 111, and multiple tools 400 are placed on the crossbars 112, arranging them longitudinally and transversely on the same vertical plane. Furthermore, the machining assembly 530 is equipped with multiple machining spindles, and multiple sets of tools 400 are provided, with the number of tool sets matching the number of machining spindles. The tool holders of the tool-retrieving robot 200 have the same number of tool sleeves as the number of machining spindles, allowing the tool-retrieving robot 200 to prepare tools for multiple machining spindles in a single round trip. See also... Figure 1 For example, if there are four machining spindles, the multiple cutting tools 400 are divided into four groups. Each group of cutting tools 400 corresponds to a spare tool for one machining spindle, and each tool holder is used to pick up and put in one group of cutting tools 400. Furthermore, the number of columns in each group of cutting tools 400 is the same, for example, see [link to relevant documentation]. Figure 3 Each set of tools 400 has four rows. Each time the tool-retrieving robot 200 retrieves or places a tool 400 from the tool 400 assembly, each tool holder operates in the same position within each set of tools 400. It should be noted that two connecting posts are located at both ends of the lower side of the frame 111, and the lower sides of the two connecting posts are respectively connected to the bed 500.
[0041] In some embodiments, see Figure 1 and Figure 2The tool-retrieving robot 200 is equipped with a translation component 210, a lifting component 220, a telescopic component 230, and a connecting component 240 for connecting the tool-retrieving sleeve. The translation component 210 is connected to the side of the tool magazine bracket 110 opposite to the gantry frame 520. The lifting component 220 is horizontally movably connected to the translation component 210. The telescopic component 230 is vertically movably connected to the lifting component 220. The connecting component 240 is movably mounted on the telescopic component 230. (See also...) Figure 1 Based on the row position of the cutting tools 400, the translation component 210 and the lifting component 220 move the tool-retrieving sleeve to the corresponding position. Then, the telescopic component 230 pushes the tool-retrieving sleeve towards the tool magazine assembly 100 to retrieve the cutting tools 400. Afterward, the telescopic component 230 pulls the tool-retrieving sleeve back away from the tool magazine assembly 100 to proceed to the next operation. This utility model's tool-retrieving robot 200, through optimized structure and in conjunction with the tool magazine assembly 100 where the cutting tools 400 are positioned on the same vertical plane, effectively expands the tool magazine capacity while reducing costs and significantly improving tool changing speed.
[0042] In some embodiments, see Figure 3 and Figure 4 The translation assembly 210 includes a translation fixing plate 211, a translation slide plate 212, and a translation connecting plate 213. The translation fixing plate 211 is disposed on the upper side of the frame 111 of the tool holder. The translation slide plate 212 is movably disposed on the translation fixing plate 211 and is connected to a translation conveyor belt 214. The translation conveyor belt 214 is sleeved on rollers, and the rollers are connected to a translation rotary motor 215, so that the translation slide plate 212 is moved by the translation rotary motor 215. The translation connecting plate 213 is horizontally disposed above the tool 400 of the tool magazine assembly 100. The two sides of the translation connecting plate 213 are respectively connected to the translation slide plate 212 and the lifting assembly 220, thereby driving the lifting assembly 220 to move left and right.
[0043] In some embodiments, see Figure 2 and Figure 3The lifting assembly 220 includes a lifting fixing plate 221, a lifting guide rail 222, and a lifting slide plate 223. The lifting fixing plate 221 is vertically arranged, and one side of the lifting fixing plate 221 is connected to one side of the translation connecting plate 213. The other side of the lifting fixing plate 221 is connected to the lifting guide rail 222. The lifting guide rail 222 is vertically arranged, and the lifting slide plate 223 is movably arranged on the lifting guide rail 222. The lifting slide plate 223 is connected to the telescopic assembly 230. The lifting slide plate 223 is connected to the lifting motor, which drives the telescopic assembly 230 to move up and down. Further, the lifting guide rail 222 is parallel to the vertical plane where the tool 400 is located in the tool magazine assembly 100. Further, two sets of translation assemblies 210 are provided. The two sets of translation assemblies 210 are respectively connected to the upper and lower ends of the telescopic guide rail 232, making the movement of the tool-retrieving robot 200 more stable. The two translation connecting plates 213 are respectively arranged above and below the tool 400 of the tool magazine assembly.
[0044] In some embodiments, see Figure 3 and Figure 5 The telescopic assembly 230 includes a telescopic fixing plate 231, a telescopic guide rail 232, and a telescopic sliding plate 233. The telescopic fixing plate 231 is L-shaped. The vertical plate of the telescopic fixing plate 231 is connected to the lifting sliding plate 223. The horizontal plate of the telescopic fixing plate 231 is connected to the upper side of the telescopic guide rail 232. The lower side of the telescopic guide rail 232 is connected to the telescopic sliding plate 233. The lower side of the telescopic sliding plate 233 is connected to the connecting assembly 240. The telescopic sliding plate 233 is connected by a telescopic cylinder to realize the extension and retraction of the connecting assembly 240.
[0045] In some embodiments, see Figure 3 and Figure 5 The connecting assembly 240 includes a fixed rod 241, a connecting rod 242, and a mounting block 243. The fixed rod 241 is connected to the telescopic slide plate 233. The two ends of the connecting rod 242 are connected to the fixed rod 241 and the mounting block 243, respectively. The mounting block 243 is equipped with a tool-retrieving sleeve and a tool-retrieving motor 244. The tool-retrieving motor 244 drives the tool-retrieving sleeve to move up and down, thereby realizing the retrieval and placement of the tool 400. Further, the fixed rod 241 is horizontally arranged and perpendicular to the telescopic guide rail 232. The fixed rod 241 is parallel to the vertical plane where the tool 400 of the tool magazine assembly 100 is located. The connecting rod 242 is horizontally arranged and perpendicular to both the fixed rod 241 and the telescopic guide rail 232. The connecting rod 242 is located on the side of the fixed rod 241 near the tool magazine assembly 100, and the mounting block 243 is located on the end of the connecting rod 242 near the tool magazine assembly 100. When there are multiple tool holders, there are correspondingly multiple connecting rods 242. One connecting rod 242 connects to one tool holder, and multiple connecting rods 242 are respectively set on both sides of the telescopic guide rail 232.
[0046] Understandably, see Figure 2The transfer assembly 320 on the transfer device 300 is equipped with a fixture 410 for placing workpieces. The tool 400 support is also equipped with a fixture 410 of the same structure for placing workpieces. Further, the fixture 410 has a U-shaped structure. Correspondingly, the tool 400 is provided with a slot, which drives the tool 400 to move horizontally, allowing the U-shaped part to enter the fixture 410 and the tool 400 to be engaged in the fixture 410. The tool holder can clamp the tool 400 from above, thereby driving the tool 400 to move. Specifically, after the tool retrieving motor 244 pushes the tool retrieving sleeve downwards to clamp the tool 400, the tool retrieving robot 200 moves the tool retrieving sleeve, causing the tool 400 to disengage from the fixture 410 on the tool magazine assembly 100 and enter the fixture 410 on the intermediate loading device. Then, the tool retrieving motor 244 pulls the tool retrieving sleeve upwards, and under the action of the fixture 410 and the slot, the tool 400 disengages from the tool retrieving sleeve. Similarly, the process of the tool retrieval robot 200 transferring the tool 400 from the transfer device 300 to the tool magazine assembly 100 can be described. It should be noted that the openings of the clamps 410 of the tool magazine assembly 100 and the clamps 410 of the transfer device 300 both face the tool retrieval robot 200.
[0047] In some embodiments, see Figure 1 and Figure 2 The transfer base plate 310 is equipped with multiple transfer components 320, each of which has two transfer fixtures 410, for example, a first transfer fixture 410 and a second transfer fixture 410. When the first transfer fixture 410 of the transfer device 300 is loaded with the next process tool 400 and moves below the machining component 530, the machining component 530 places the current process tool 400 into the second transfer fixture 410. Then, the machining component 530 can load the tool 400 from the first transfer fixture 410 for the next process. Thus, the machining component 530 can complete the tool placement and removal actions in one round trip, which improves the tool change speed. Furthermore, the number of transfer fixtures 410 is the same as the number of spindles on the machining component 530, thereby enabling the simultaneous replacement of tools 400 on multiple machining spindles.
[0048] In some embodiments, see Figure 1 and Figure 4 The transfer assembly 320 includes a transfer connecting plate 322 and two transfer fixing plates 321. The transfer base plate 310 is horizontally arranged and parallel to the vertical plane where the tool 400 of the tool magazine assembly 100 is located. The two transfer fixing plates 321 are vertically arranged and parallel to each other. The transfer connecting plate 322 is parallel to the transfer base plate 310. The upper and lower sides of the transfer fixing plates 321 are connected to the transfer connecting plate 322 and the transfer base plate 310, respectively. A plurality of clamps 410 are arranged on the transfer connecting plate 322. Further, the plurality of clamps 410 are arranged side by side in the left-right direction.
