Description

Technical Field

[0001] This utility model relates to a tool magazine device for providing replacement cutting tools for machine tools, and in particular to an innovative structural form of a tool magazine device with an exchangeable track. Background Technology

[0002] Numerical control machine tools are equipped with a tool magazine. Various types and specifications of cutting tools required for machining are stored in the tool magazine. According to the machining program settings, the machine tool retrieves the type and specifications of cutting tools required for the next machining process from the tool magazine.

[0003] The tool magazine includes a support structure, a track device, a braking device, and several tool holders for holding tools. The track device and the braking device are disposed on the support structure. The track device has a fixed, closed, circular track groove that forms a ring-shaped path. Several rollers are arranged sequentially and closely in the track groove. Each roller has a radially formed annular groove on its rim. Each tool holder is connected to one or more rollers. The braking device has a braking wheel with several protruding teeth spaced apart on its rim. When the braking wheel rotates, each protruding tooth sequentially enters the space formed by the annular grooves of two adjacent rollers and pushes the adjacent rollers along the track groove, thereby sequentially pushing each roller to move cyclically along the ring-shaped path.

[0004] Tool magazines are typically equipped with multiple tool holders to hold various types and sizes of cutting tools. However, different machine tools or different machining operators usually have different machining needs, and the number of cutting tools that need to be stored in the tool magazine varies. In order to ensure that the tool magazine can meet the potential increase in machining needs in the future, machining operators usually choose to configure a tool magazine with a larger number of tool holders than the current number of cutting tools needed. The number of tool holders is positively correlated with the size of the track device, which increases the required planar space for setting up the tool magazine. Utility Model Content

[0005] The main objective of this invention is to provide a tool magazine device with an interchangeable track. To achieve this objective, this invention is implemented as follows.

[0006] A tool magazine device with interchangeable tracks includes a support frame, a first track unit, a second track unit, a third track unit, a linear drive unit, and a braking unit. The support frame connects the first track unit and the linear drive unit, and the linear drive unit connects the second track unit and the third track unit, thereby driving the second track unit and the third track unit to move linearly relative to the first track unit.

[0007] The first track unit forms a first track groove, and the two ends of the first track groove are respectively opened to the outside to form two first connecting ports.

[0008] The second track unit forms a second track groove, and the two ends of the second track groove are respectively opened to the outside to form two second connecting ports. The distance between each second connecting port is equal to the distance between each first connecting port.

[0009] The third track unit forms a third track groove, and the two ends of the third track groove are respectively opened to the outside to form two third connecting ports. The distance between each third connecting port is equal to the distance between each first connecting port.

[0010] The second and third track units are arranged at intervals, so that the second and third track grooves alternately connect with the first track groove, thereby forming a ring-shaped operating space.

[0011] Several rollers are arranged closely in sequence in the first, second, and third rail grooves.

[0012] Several tool holders, each used to hold a tool, and each tool holder is connected to at least one roller.

[0013] The braking unit is connected to the first track unit and is used to move each roller.

[0014] The outstanding and beneficial technical effects of this utility model compared to the prior art are as follows.

[0015] The second and third track units can be selectively and alternately used in conjunction with the first track unit. When the number of tool holders is increased, the plane space occupied by the tool holders can be increased without increasing the increase in the number of tool holders. The plane space occupied by the tool holders can be increased with a smaller increase, thus achieving practical progress. Attached Figure Description

[0027] like Figures 1 to 10 As shown, a preferred embodiment of the tool magazine device with interchangeable tracks includes a support frame 10, a first track unit 20, a second track unit 30, a third track unit 40, a linear drive unit 50, and a braking unit 90. The support frame 10 connects the first track unit 20 and the linear drive unit 50, and the linear drive unit 50 connects the second track unit 30 and the third track unit 40. The second track unit 30 and the third track unit 40 are spaced apart, and the linear drive unit 50 drives the second track unit 30 and the third track unit 40 to move linearly relative to the first track unit 20.

[0028] The first track unit 20 forms a first track groove 21, with two ends of the first track groove 21 opening to the outside to form two first connecting ports 22. The second track unit 30 forms a second track groove 31, with two ends of the second track groove 31 opening to the outside to form two second connecting ports 32. The distance between each second connecting port 32 is equal to the distance between each first connecting port 22, so that each first connecting port 22 can selectively connect to each second connecting port 32, and the first track groove 21 can selectively connect to the second track groove 31 to form a ring-shaped running space.

[0029] The third track unit 40 forms a third track groove 41. The two ends of the third track groove 41 are respectively open to the outside to form two third connecting ports 42. The distance between each third connecting port 42 is equal to the distance between each first connecting port 22, so that each first connecting port 22 can be selected to connect to each third connecting port 42, and the first track groove 21 can be selected to connect to the third track groove 41 to form another ring-shaped running space.

[0030] Several rollers 60 are arranged in a close sequence in the first rail groove 21, the second rail groove 31 and the third rail groove 41. Several tool holders 70 are used to set a tool (not shown in the figure). Each tool holder 70 is connected to at least one roller 60. Each tool holder 70 is selectively connected to two rollers 60, and it is not limited that each roller 60 needs to be connected to a tool holder 70.

[0031] When the first track 21 connects to the second track 31, several rollers 60 sequentially cycle or reciprocate along the running space formed by the first track 21 and the second track 31, while several rollers 60 located in the third track 41 remain in the third track 41 and do not run.

[0032] The braking unit 90 is connected to the first track unit 20 and is used to push each roller 60 to run. The braking unit 90 is a conventional structure known to those skilled in the art to which this utility model pertains, and the specific structure of the braking unit 90 will not be described in detail.

[0033] The second track unit 30 and the third track unit 40 can be selectively and alternately cooperated with the first track unit 20. When the number of tool holders 70 is increased, the preferred embodiment can increase the plane space occupied by them without increasing the number of tool holders 70, or increase the plane space occupied by them with a smaller increase relative to the increase in the number of tool holders 70.

[0034] Each roller 60 has a connecting part 62 formed in its axial direction. Two first stops 23 are respectively connected to the first track unit 20, two second stops 33 are respectively connected to the second track unit 30, and two third stops 43 are respectively connected to the third track unit 40.

[0035] Each first stopper 23 includes a first mounting seat 24, a first shaft 25, a first stop block 26, a first disc-shaped component 27, a first annular piece 28, and a first spring 29. Each first mounting seat 24 is connected to a first track unit 20. Each first shaft 25 is axially pivoted through each first mounting seat 24, so that each first shaft 25 can reciprocate along its axial direction. Each first shaft 25 is connected to a first stop block 26 at one end of its axial direction. Each first stop block 26 is used to block a connecting part 62, so that each first stopper 23 relatively restricts several rollers 60 from running in the first track groove 21.

[0036] Each second stopper 33 includes a second mounting seat 34, a second shaft 35, a second stop block 36, a second disc-shaped piece 37, a second annular piece 38, and a second spring 39. Each second mounting seat 34 is connected to the second track unit 30. Each second shaft 35 is axially pivoted through each second mounting seat 34, so that each second shaft 35 can reciprocate along its axial direction. Each second shaft 35 is connected to a second stop block 36 at one end of its axial direction. Each second stop block 36 is used to block a connecting part 62, so that each second stopper 33 relatively restricts several rollers 60 from running in the second track groove 31.

[0037] Each third stopper 43 includes a third mounting seat 44, a third shaft 45, a third stop block 46, a third disc-shaped piece 47, a third annular piece 48, and a third spring 49. Each third mounting seat 44 is connected to a third track unit 40. Each third shaft 45 is axially pivoted through each third mounting seat 44, so that each third shaft 45 can reciprocate along its axial direction. Each third shaft 45 is connected to a third stop block 46 at one end of its axial direction. Each third stop block 46 is used to block a connecting part 62, so that each third stopper 43 relatively restricts several rollers 60 from running in the third track groove 41.

[0038] A traction unit 80 is disposed on the support frame 10 and is positioned between each of the first stops 23. Accordingly, it actuates each of the first stops 23 and the adjacent second stops 33 or third stops 43, thereby selectively opening several rollers 60 to run along the running space formed by the first track groove 21 and the second track groove 31, or selectively opening several rollers 60 to run along the running space formed by the first track groove 21 and the third track groove 41.

[0039] Each first shaft 25 is connected to a first disc-shaped component 27, each second shaft 35 is connected to a second disc-shaped component 37, and each third shaft 45 is connected to a third disc-shaped component 47. This causes the traction unit 80 to actuate each first disc-shaped component 27 and its adjacent second disc-shaped component 37 or third disc-shaped component 47, thereby enabling each roller 60 to run.

[0040] Each first shaft 25 is connected to a first annular plate 28 and fitted with a first spring 29. Each first spring 29 abuts against each first annular plate 28 and each first mounting seat 24. The traction unit 80 actuates each first stopper 23, releasing each first stop block 26 from stopping a corresponding roller 60. Each first spring 29 provides elastic force to reset each first shaft 25, so that each first stop block 26 returns to stopping a corresponding roller 60.

[0041] Each second shaft 35 is connected to a second annular plate 38 and fitted with a second spring 39. Each second spring 39 abuts against each second annular plate 38 and each second mounting seat 34. The traction unit 80 actuates each second stopper 33, releasing each second stop block 36 from stopping one of its opposite rollers 60. Each second spring 39 provides elastic force to reset each second shaft 35, so that each second stop block 36 returns to stopping one of its opposite rollers 60.

[0042] Each third shaft 45 is connected to a third annular plate 48 and fitted with a third spring 49. Each third spring 49 abuts against each third annular plate 48 and each third mounting seat 44. The traction unit 80 actuates each third stopper 43, releasing each third stop block 46 from stopping one of its opposite rollers 60. Each third spring 49 provides elastic force to reset each third shaft 45, so that each third stop block 46 returns to stopping one of its opposite rollers 60.

[0043] The traction unit 80 includes two pneumatic cylinders 82, each pneumatic cylinder 82 having a piston rod 84, each piston rod 84 being connected to an actuating disc 86, each actuating disc 86 extending between each first disc-shaped member 27 and each first mounting seat 24, thereby causing each piston rod 84 to drive each actuating disc 86 to actuate each first disc-shaped member 27 and its adjacent second disc-shaped member 37 or third disc-shaped member 47, thereby releasing the obstruction to each connecting part 62.

[0044] Each pneumatic cylinder 82 can be replaced with a hydraulic cylinder, thereby constituting a replacement implementation option that is readily conceived based on the preferred embodiment.

[0045] like Figure 6 As shown, the first track groove 21 is connected to the second track groove 31. Each first stop block 26 and each second stop block 36 abut against a connecting part 62 to form a stop on each connecting part 62. During the subsequent movement of the second track unit 30, each roller 60 located in the first track groove 21 and the second track groove 31 can be left in the first track groove 21 and the second track groove 31 respectively.

[0046] like Figure 8As shown, the first track 21 is connected to the second track 31, and the traction unit 80 actuates each of the first stop blocks 26 and each of the second stop blocks 36 to release the abutment restriction on their respective connecting parts 62. Each of the rollers 60 located in the first track 21 and the second track 31 can run sequentially along the first track 21 and the second track 31.

[0047] like Figure 7 As shown, the third track groove 41 is not connected to the first track groove 21. Each third stop block 46 abuts against a connecting part 62. Each roller 60 located in the third track groove 41 can be placed in the third track groove 41.

[0048] like Figure 9 As shown, the second track unit 30 and the third track unit 40 are driven by the linear drive unit 50, such that the third track unit 40 replaces the second track unit 30 and is opposite to the first track unit 20, and the third track groove 41 replaces the second track groove 31 and connects to the first track groove 21, as shown. Figure 10 As shown, each first stop 26 and each third stop 46 abuts against a connecting part 62 opposite to it, thereby restricting each roller 60 located in the first track groove 21 and the third track groove 41 respectively.

[0049] The linear drive unit 50 includes two rails 51, two slides 52, a ball screw 53, and a drive motor 54. Each rail 51 is parallel to each other and connected to the support frame 10. Each slide 52 can slide along each rail 51 and pivotally mount each rail 51. Each slide 52 is coupled to the second track unit 30 and the third track unit 40. The drive motor 54 is connected to the support frame 10. The drive motor 54 and the slides 52 are respectively connected to the ball screw 53. Accordingly, the drive motor 54 drives the ball screw 53 to rotate. The ball screw 53 pulls the slides 52 and, guided by each rail 51, drives the second track unit 30 and the third track unit 40 to move linearly back and forth.

[0050] Specifically, each slide 52 is connected to a connecting part 55, and each slide 52 is coupled to the second track unit 30 and the third track unit 40 through the connecting part 55.

[0051] The traction unit 80 can be optionally replaced with two electromagnetic brakes (not shown in the figure), thereby constituting an alternative embodiment based on the preferred embodiment, wherein each electromagnetic brake corresponds to magnetically actuating each first shaft 25 and its adjacent second shaft 35 or third shaft 45, thereby releasing the obstruction to each connecting part 62.
