Description

Technical Field

[0001] This utility model relates to a tool magazine system, and more particularly to a lifting tool magazine mechanism. Background Technology

[0002] To improve work efficiency, machining machines are equipped with tool magazines, such as hat-shaped tool magazines, chain-type tool magazines, and disc-type tool magazines, and used in conjunction with tool arms to enhance operational efficiency.

[0003] However, through practical experience, relevant technical personnel discovered that the previous tool magazines had the following technical problems:

[0004] 1. Inability to change tools in multiple directions: Most commercially available tool magazines can only change tools in the same direction. For example, when the spindle is clamped to the side, it is not possible to change tools in multiple directions within the same tool magazine. Otherwise, a complex structure would be required to change the direction.

[0005] 2. Problems with small tool magazine capacity and single-specification tool holders: Commercially available tool magazines can only hold a limited number of tools, and the same tool magazine cannot support tools with different specifications of tool holders. For example, when the specifications of the side taper hole of the spindle clamping are different from those of the spindle taper hole, the versatility is limited.

[0006] Third, they occupy a lot of space: In addition, the structure of commercially available tool magazines is complex, so they cannot effectively reduce the size of the tool magazine, but instead increase the size of the machining machine.

[0007] In view of this, those skilled in the art are actively developing a technical solution to address the above-mentioned problems in order to improve the deficiencies of the existing technology. Utility Model Content

[0038] Please see Figures 1 to 3 A lifting tool magazine mechanism 100 is disposed on a machining machine 10. The machining machine 10 has a work platform 11 and at least one spindle 12. The machining machine 10 has a base 13, on which the work platform 11 is disposed. The base 13 has a column 14. The spindle 12 is movable along the Y-axis and is disposed on the column 14. The lifting tool magazine mechanism 100 includes a lifting tool storage device 20 and a tool exchange device 30. In this embodiment, the spindle 12 is slidable along the Z-axis and is arranged with its axis parallel to the Y-axis.

[0039] Please see Figure 3 and Figure 4 The lifting-type tool storage device 20 has a lifting unit 21 that moves along the Y-axis. The lifting unit 21 is provided with a plurality of tool holders 22 from top to bottom. Each tool holder 22 has at least one tool 23. The tool holder 22 moves up and down through the lifting unit 21 and switches between a plurality of tool storage positions P1 and a tool changing position P2.

[0040] Please see Figures 5 to 7The tool changing device 30 is capable of disengaging the tool holder 22 at the tool changing holder position P2 and moving the corresponding tool holder 22 along at least one of the X-axis or Z-axis from the tool changing holder position P2 to a tool changing position P3, so that the spindle 12 can remove or return the tool 23 from the tool holder 22, or return the tool holder 22 to the corresponding lifting unit 21 along the X-axis at the tool changing holder position P2, so that the tool holder 22 can run again along the Y-axis to the multiple tool storage position P1.

[0041] Please continue reading. Figures 1 to 7 The machining machine 10 has a frame 15 on each of the inner walls of the two sides of the column 14. The tool changing device 30 includes an X-axis drive unit 31, a tool holder rotation drive unit 33 that rotates around the Z-axis, and a locking unit 32. The X-axis drive unit 31 is located on the frame 15 and is used to drive one of the tool holders 22 to move along the X-axis. The tool holder rotation drive unit 33 is used to rotate the tool holder 22 along with the tool 23 around the Z-axis. The locking unit 32 is used to lock the locking holes 221 at both ends of the corresponding tool holder 22. With the above structure, the tool changing device 30 improves the efficiency of the tool holder 22 changing process, and can quickly and accurately move the tool holder 22 to the predetermined position. The tool holder rotation drive unit 33 drives the tool holder 22 along with the tool 23 to rotate around the Z-axis according to the tool changing requirements of the spindle 12, and the locking unit 32 quickly locks the locking holes 221 at both ends of the tool holder 22, which can increase the efficiency and stability of the changing process.

[0042] Please see Figure 3 and Figure 4 The multiple tool holders 22 are mounted on the lifting unit 21 via a positioning frame 24. The positioning frame 24 has multiple symmetrical support arms 241, and the multiple tool holders 22 are respectively mounted on the corresponding multiple support arms 241. Through the above structure, the positioning frame 24 and its symmetrical support arms 241 provide stable structural support, ensuring the stability of the tool holders 22 after positioning.

[0043] Please continue reading. Figure 3 and Figure 4 The lifting unit 21 comprises two sliding mechanisms 211, a lifting plate 212, and a driving unit 213. The sliding mechanisms 211 are mounted on the back of the machining machine 10. A positioning frame 24 is fixed above the lifting plate 212, and the lifting plate 212 is connected to the sliding mechanisms 211. The driving unit 213 drives the lifting plate 212 to move horizontally along the Y-axis relative to the sliding mechanisms 211. Through this structure, the lifting unit 21 provides precise Y-axis motion control, making the movement of the tool holder 22 between different tool storage positions P1 and tool change positions P2 more accurate.

[0044] Please continue reading. Figure 3 and Figure 4Each sliding mechanism 211 includes a slide rail 2111 and a slide block 2112. The slide rails 2111 are respectively fixed to the back sides of both sides of the processing machine 10, and the slide blocks 2112 slide on the corresponding slide rails 2111, and the slide blocks 2112 are symmetrically fixed on both sides of the lifting plate 212. Through the above structure, the sliding mechanism 211 formed by the slide rails 2111 and the slide blocks 2112 ensures the smooth operation of the lifting unit 21 in the Y-axis direction.

[0045] Please see Figures 1 to 7 The working principle of this utility model is as follows:

[0046] 1. Tool storage process: In the initial state, the tool holder 22 is in the tool storage position P1. These positions are distributed along the Y-axis direction of the lifting unit 21, and each tool holder 22 is mounted on the lifting unit 21.

[0047] 2. Lifting process: When it is necessary to replace the tool holder 22, the lifting unit 21 can move along the Y-axis to move the designated tool holder 22 from its tool storage position P1 to the tool changing position P2.

[0048] 3. Removal of tool holder 22 and exchange of tool 23: When the tool holder 22 reaches the tool changer position P2, the tool exchanger 30 moves along the X-axis. After locking the tool holder 22 at the tool changer position P2, the tool exchanger 30 moves along the X-axis, causing the tool holder 22 to disengage from the lifting tool storage device 20 and move to the tool changer position P3, so that the spindle 12 can accurately align with the tool holder 22, thereby performing the tool 23 pick-up and drop operation.

[0049] 4. Tool holder 22 returns to its original position: After the tool 23 in the tool holder 22 has been used, the tool exchange device 30 will move the tool holder 22 back to the tool changer position P2 along the X-axis and release the lock. Then, the lifting unit 21 will start again to move the tool holder 22 from the tool changer position P2 back to the tool storage position P1. This process ensures that the tool 23 is properly stored when not in use and ready for the next use.

[0050] 5. Rotation process of tool holder 22: Please refer to Figure 10 When the tool changing direction of the spindle 12 is inconsistent with the direction of the tool 23, the tool holder rotation drive unit 33 needs to be controlled to make the locked tool holder 22 rotate around the Z-axis to match the tool changing direction of the spindle 12.

[0051] Please see Figure 11 When the spindle 12 of the machining machine 10 can only move along the Y-axis, a Z-axis drive unit 34 can be added to the X-axis drive unit 31 of the tool changing device 30 to drive one of the tool holders 22 to move along the X-axis and Z-axis, so as to complete the tool changing action of the spindle 12.

[0052] Please see Figure 8 The tool changing device 30 can also be installed on both sides of the work platform 11, and the tool changing device 30 can move along the X-axis or along the X-axis and Z-axis along with the work platform 11. With the above structure, the tool changing device 30 saves material costs such as the X-axis drive unit 31 or the X-axis drive unit 31 and Z-axis drive unit 34.

[0053] Please see Figure 9 The tool holder 22 and the tool 23 can also be stored horizontally to increase the number of tool holders 22 and the tool 23, or to meet the needs of tool changing direction.

[0054] With the above structure, the advantages of this utility model are as follows:

[0055] 1. Efficient tool replacement 23: The lifting tool magazine mechanism 100 of this utility model, through the coordinated operation of the lifting tool storage device 20 and the tool exchange device 30, enables the lifting unit 21 to quickly locate and select the required tool holder 22 position, greatly shortening the tool holder 22 exchange time, so as to achieve the purpose of efficient tool replacement 23.

[0056] 2. High space utilization efficiency: Please refer to Figure 4 and Figure 9 The present invention, through the design of the lifting-type tool storage device 20, allows multiple tool holders 22 to be arranged along the Y-axis. This storage method can effectively reduce the space required for storing the tools 23.

[0057] 3. High versatility: This utility model, through the design of the tool holder rotation drive unit 33, rotates the tool holder 22 according to the tool changing direction of the spindle 12 to achieve the function of multi-directional tool changing.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
