Description

Technical Field

[0001] This utility model relates to a tool magazine mechanism, and more particularly to a pivot-type 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 are 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 perform multi-directional tool changes: Most tool magazines sold on the market can only change tools in the same direction. For example, when the spindle is equipped with a side head or the spindle tool changing direction is different from the tool direction, it is not possible to perform multi-directional tool changes in the same tool magazine. Otherwise, a complex structure is required to achieve the turning direction.

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

[0006] Third, they occupy a lot of space: In addition, the tool magazines sold on the market have complex structures and cannot effectively reduce the size of the tool magazine, thus increasing 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

[0008] In view of the above situation, it is necessary to provide a pivoting tool magazine mechanism that solves at least one of the above problems, which is disposed in a machining machine having at least one spindle, a tool storage area and a tool changing area, the pivoting tool magazine mechanism comprising:

[0009] A tool storage device is located in the tool storage area. The tool storage device has at least one tool placement component and a steering module.

The drive gear is poweredly connected to the first power unit, and the drive gear is movably meshed with the reversing gear, causing the bracket to pivot along the XY plane between the first position and the second position.

[0012] Preferably, the tool storage device is provided with multiple sets of tool placement components stacked along the Z-axis. The tool placement components move up and down along the Z-axis, and one set of reversing gears is positioned at the first position, while the other reversing gears are positioned at the standby position of the tool storage area.

The lifting seat is connected to the second power unit, and the lifting rod is arranged on the lifting seat along the Z-axis. The reversing gear of the tool placement assembly is spaced apart on the lifting rod along the Z-axis.

[0014] Preferably, each of these tool-holding assemblies has a guide rail connected to the tool holders, allowing the tool holders to slide on the supports. The tool changing device has a pushing module and an up-and-down module. When one of the supports is in the second position, the up-and-down module moves the pushing module downward to the tool changing area. At this time, the pushing module can push the tool holder in the second position, causing the guide rail to slide on the support, and then the tool holder moves along the X-axis to switch between the second position and the tool changing position.

[0015] Preferably, each of these tool holders has a first engaging portion, and the pushing module has a second engaging portion. When one of the tool holders moves to the tool changing area, the upper and lower modules move the pushing module down to the tool changing area, thereby engaging the first engaging portion and the second engaging portion to push the tool holder located in the second position.

[0016] Preferably, it further includes a rotating device located on the side of the tool changing area. The rotating device includes a limiting module, and when the bracket is in the second position, the bracket is connected to the limiting module.

[0017] Preferably, the bracket has a second end and a shaft. The second end is located at the other end of the bracket opposite to the first end, and the shaft is adjacent to the first end, allowing the bracket to rotate around the shaft.

[0018] Preferably, when the second end of the bracket is connected to the limiting module, the rotating device drives the second end of the bracket to rotate around the axis of the bracket, so that the tool rotates together and the tool conforms to the tool changing direction of the spindle.

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the pivotal tool magazine mechanism of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0036] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "center," "longitudinal," "lateral," "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and 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, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art will be able to understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] Please see Figure 1 Please refer to the embodiments of this utility model. Figure 1 The machining machine 1 has at least one spindle 1a, a work platform 1b, a tool storage area S, and a tool changing area C. The number of spindles 1a can be single or multiple. The tool storage area S is adjacent to the tool changing area C. The spindle 1a is located in the tool changing area C for tool changing operations. In this embodiment, the spindle 1a can slide along the Y-axis and its axis 112a is parallel to the Z-axis.

[0039] The pivot-type tool magazine mechanism 100 includes a tool storage device 10 and a tool changing device 20.

[0040] Please see Figures 1 to 3 The tool storage device 10 is located in the tool storage area S. The tool storage device 10 has at least one tool placement assembly 11 and a steering module 12. The tool placement assembly 11 is pivotally connected to the steering module 12, and the tool placement assembly 11 simultaneously stores multiple sets of tools 2. Figure 3 As shown, the steering module 12 can drive the tool-holding assembly 11 to pivot along the XY plane, thereby allowing the tool-holding assembly 11 to switch between a first position P1 in the tool storage area S and a second position P2 in the tool changing area C. Since the first position P1 and the second position P2 are approximately L-shaped, this frees up working space to facilitate the operation of the machining machine 1.

[0041] The pivotal tool magazine mechanism 100 also includes a rotating device 30 located on the side of the tool changing area C. The rotating device 30 can rotate a bracket 112 of the tool holding assembly 11, thereby aligning the tool 2 with the tool changing direction of the spindle 1a to achieve multi-directional tool changing function.

[0042] Please see Figure 4 In one embodiment of this disclosure, each tool mounting assembly 11 has a reversing gear 111, a bracket 112, and a tool holder 113. A first end E1 of the bracket 112 is connected to the reversing gear 111. The tool holder 113 is slidably disposed on the bracket 112, that is, the tool holder 113 can slide on the bracket 112.

[0043] Please see Figure 4The steering module 12 has a first power unit 121 and a drive gear 122. In this embodiment, the first power unit 121 can be a motor. The drive gear 122 is powered by the first power unit 121, and the first power unit 121 drives the drive gear 122 to rotate clockwise or counterclockwise. Furthermore, the drive gear 122 is movably engaged with the reversing gear 111, meaning the drive gear 122 selectively engages with or disengages from the reversing gear 111. Based on the aforementioned technical features, the bracket 112 can pivot along the XY plane between a first position P1 and a second position P2 to transport or store the tool 2. Please refer to... Figure 4 To increase the number of tools 2 that can be stored, the tool storage device 10 has multiple tool placement assemblies 11 stacked along the Z-axis. (See also...) Figure 5 Multiple tool-holding assemblies 11 can move up and down along the Z-axis, and one set of reversing gears 111 can be positioned at a first position P1, while the other reversing gears 111 are positioned at a standby position P3 in the tool storage area S. The standby position P3 can be above or below the first position P1. When one set of reversing gears 111 is positioned at the first position P1, the reversing gear 111 at the first position P1 meshes with the drive gear 122, and the first power unit 121 drives the drive gear 122 and the reversing gear 111 to rotate, allowing the bracket 112 at the first position P1 to switch between the first position P1 and the second position P2.

[0044] In one embodiment of this disclosure, the tool storage device 10 has a lifting module 13. The lifting module 13 has a second power unit 131, a lifting seat 132, and a lifting rod 133. In this embodiment, the second power unit 131 may be a combination of a motor, a screw, and a linear guide. The lifting seat 132 is connected to the second power unit 131, and the second power unit 131 drives the lifting seat 132 to move up and down along the Z-axis to displace multiple tool placement assemblies 11. The lifting rod 133 is disposed on the lifting seat 132 along the Z-axis direction, and the lifting rod 133 moves up and down with the movement of the lifting seat 132. The reversing gears 111 of each tool placement assembly 11 are spaced apart on the lifting rod 133 along the Z-axis direction. Further, multiple reversing gears 111 pass through the lifting rod 133, so that the multiple reversing gears 111 are arranged in series on the lifting rod 133, and each reversing gear 111 is in a transverse form, thereby engaging with the drive gear 122.

[0045] The tool changer 20 is located in tool change zone C. Please refer to [link / reference]. Figure 6 When the tool placement assembly 11 is in the second position P2, the tool changing device 20 can drive the tool placement assembly 11 to switch between the second position P2 and a tool changing position P4 in the tool changing area C along the X-axis direction, so that the spindle 1a can remove or put back the tool 2 from the tool placement assembly 11.

[0046] During the tool retrieval operation, the tool holder 113 carries the tool 2, and the tool changer 20 drives the tool holder 113 to move from the second position P2 to the tool change position P4 along the X-axis. When the tool holder 113 is in the tool change position P4, the spindle 1a descends to the tool change position P4 along the Z-axis to grab the tool 2. Then, after the spindle 1a grabs the tool 2, it rises to reset, and the tool holder 113 returns to the second position P2 to complete the tool retrieval operation.

[0047] During the tool return operation, the spindle 1a moves along the Y-axis to the tool holder 113 where the tool 2 is not being held, and then descends along the Z-axis to the tool change position P4. The tool changer 20 drives the tool holder 113 along the X-axis from the second position P2 to the tool change position P4, causing the tool holder 113 to clamp the tool 2. After the spindle 1a releases the tool, it rises again along the Z-axis to its original position, while the tool holder 113 returns to the second position P2, thus completing the tool return operation.

[0048] In one embodiment of this disclosure, multiple blade-holding assemblies 11 each have a guide rail 114. The multiple guide rails 114 are connected to multiple blade holders 113, allowing the multiple blade holders 113 to slide on multiple supports 112. In this embodiment, each set of guide rails 114 consists of two rails, connected to both sides of each blade holder 113. Please refer to... Figure 6 and Figure 7 The tool changing device 20 has a pushing module 21 and a lifting module 22. When one of the brackets 112 is in the second position P2, the lifting module 22 moves the pushing module 21 downward to the tool changing area C. At this time, the pushing module 21 can push the tool holder 113 located in the second position P2, so that the guide rail 114 slides on the bracket 112, thereby allowing the tool holder 113 to switch between the second position P2 and the tool changing position P4 along the X-axis direction.

[0049] Please see Figure 3 Each of the multiple tool holders 113 has a first engaging portion 113a. The pushing module 21 has a second engaging portion 211. When the upper and lower modules 22 move the pushing module 21 down to the tool changing area C, the first engaging portion 113a and the second engaging portion 211 engage with each other, and then the pushing module 21 pushes the tool holder 113 located at the second position P2. Further, each first engaging portion 113a has a groove at its top, and each second engaging portion 211 has a protrusion at its bottom. The shape of the groove matches the shape of the protrusion to engage with each other.

[0050] Please see Figure 8To secure the tool holder assembly 11 at the second position P2, the rotating device 30 of the pivoting tool magazine mechanism 100 further includes a limiting module 31. The limiting module 31 is located on the side of the tool changing area C. The limiting module 31 has the same height as the tool holder assembly 11 at the second position P2. When the bracket 112 is in the second position P2, the bracket 112 engages with the limiting module 31 to ensure the position of the tool holder assembly 11.

[0051] Please see Figure 9 In this embodiment, the cutting tool 2 is in a horizontal position. Please refer to [link / reference]. Figure 8 and Figure 10 To accommodate the horizontally positioned cutting tool 2, the support 112 has a second end E2 and a shaft 112a. The second end E2 is located at the other end of the support 112 opposite to the first end E1. The shaft 112a is adjacent to the first end E1; in this embodiment, the shaft 112a is located at a corner of the support 112. Furthermore, the support 112 can rotate around the shaft 112a.

[0052] Please see Figure 8 To achieve multi-directional tool changing functionality, the pivoting tool magazine mechanism 100 further includes a rotating device 30. The rotating device 30 can be equipped with a rotary motor. When the second end E2 of the bracket 112 is connected to the limiting module 31, the rotating device 30 drives the second end E2 to rotate around the axis 112a of the bracket 112, thereby causing the tool 2 to rotate along with it to conform to the tool changing direction of the spindle 1a.

[0053] In summary, this disclosure has the following technical features:

[0054] 1. High efficiency: The tool storage device 10 disclosed herein only needs to pivot along the XY plane to allow the tool placement assembly 11 to switch between the tool storage area S and the tool changing area C, so that the spindle 1a can change the tool 2, thereby further increasing the efficiency of tool changing 2.

[0055] 2. Features of large capacity: The tool storage device 10 disclosed herein can store multiple sets of tools 2 simultaneously in the longitudinal or transverse direction, and can install tool holders and tools 2 of the same or different specifications, or spindle heads or side heads, etc., on the tool holder 113 as needed to meet the working requirements of the processing machine 1.

[0056] Third, it has the feature of saving space: Since the tool storage device 10 and the tool changing device 20 of this disclosure perform tool changing operations directly above the work platform 1b, this approach can reduce the volume occupied by the machining machine 1.

[0057] IV. Different Working Modes: This disclosure provides vertical, horizontal, or mixed vertical-horizontal positions for storing the tool 2 to suit different implementation scenarios. In the vertical position, it is more convenient for the spindle 1a to pick up and place the tool 2, and the structure is simpler. In the horizontal position, the vertical spacing between each tool-holding assembly 11 can be configured to be closer, which can increase the number of tool-holding assemblies 11 and thus increase the number of tools 2 that can be stored. Furthermore, when the spindle 1a is gripping a side head or when the tool-changing direction of the spindle 1a is different from that of the tool 2, the support 112 can be rotated to achieve a multi-directional mixed tool-changing function.

[0058] 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. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
