[0052] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0053] It should be noted that when an element is referred to as being "disposed on" another element, it may be directly disposed on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element. When an element is referred to as being "mounted on" another element, it may be directly mounted on the other element or there may be a central element.

[0054] In addition, it should be understood that all directional indications in the embodiments (such as up, down, left, right, middle, etc.) are only used to explain the relative position relationship, movement, etc. between the components in a certain posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly; the terms "first", "second", etc. are used to distinguish different structural components. These terms are only simplified descriptions for the convenience of describing the utility model and cannot be understood as limitations on the utility model.

[0055] The utility model provides a rotary tool magazine and a machining center equipped with the rotary tool magazine. The rotary tool magazine has double-layer protection, one layer of protection is used to protect the tool handle and the tool on the tool magazine body, and the other layer of protection is used to protect the tool handle and / or the tool handle position (for the tool handle on the spindle to be placed in the corresponding fixed position on the tool magazine body) that are partially exposed during tool change, thereby achieving a more comprehensive protection effect, which is beneficial to ensuring the stability of the operation of the machining center.

[0056] See also Figure 2, which is a schematic diagram of the structural principle of the rotary tool magazine provided by the utility model. The rotary tool magazine 1 may include a tool magazine body 11 for mounting and fixing a tool handle, and a first protection component 12 and a second protection component 13 for respectively providing protection for the tool magazine body 11. The first protection component 12 is mainly used to provide protection for the tool handle on the tool magazine body 11, while the second protection component 13 is mainly used to provide protection for the tool handle or the tool handle position that is partially exposed after rotation during the tool change process.

[0057] The first protection assembly 12 may include a protection cover 121, and the tool magazine body 11 is accommodated in the protection cover 121. The protection cover 121 has a front end portion F, and a first tool changing port 1211 is provided on the front end portion F. The first tool changing port 1211 is used for partially exposing the tool magazine body 11 outside the first tool changing port 1211 when changing tools, so as to change tools. Corresponding to the first tool changing port 1211, the tool magazine body 11 includes a door panel 113 adapted to the first tool changing port 1211.

[0058] The second protection component 13 may include a protection plate 131 having a second tool change port 1311, and the protection plate 13 is disposed on the protection cover 121. The protection plate 131 may also include a plate edge 1312 extending in the width direction of the protection cover 121 (i.e., the X-axis direction in the figure). When changing the tool, the protection plate 131 covers the first tool change port 1211, and the second tool change port 1311 is located at a preset tool change position. Here, when the second tool change port 1311 is located at the preset tool change position, the corresponding tool handle or tool handle on the tool magazine body is exposed below the second tool change port 1311, so that the front end of the spindle for installing the tool handle can be moved closer, and the front end of the spindle is supported to cooperate with the tool magazine body for unloading or installing the tool. At the same time, the plate body of the protective plate 131 forms a shield for the space around the front end of the spindle, thereby providing protection for other parts of the tool magazine body (tool handle or tool handle position) exposed along with the corresponding tool handle or tool handle position, reducing the probability of accumulated chips on the spindle box falling onto the partially exposed tool handle or tool handle position during tool changing, which is beneficial to reducing the failure rate of tool changing.

[0059] It can be understood that, in the figure, the protective cover 121 includes a top portion T, and the top portion T has an inclined top surface T1, and the inclined top surface T1 includes a high side and a low side located at different heights. The protective plate 131 is partially disposed on the inclined top surface T1 and is located on the side where the low side is located. In other specific application examples, the protective plate 131 can also be disposed on the top side of the front end F of the protective cover 121 or the lower side of the front end F. When the second tool changing port 1311 is located at the preset tool changing position, the opening direction of the second tool changing port 1311 is consistent with the opening direction of the first tool changing port 1211, thereby supporting the front end of the spindle or the tool handle on the front end of the spindle to approach the tool magazine body 11 from a distance and cooperate with the tool changing action.

[0060] It can be understood that the inclined top surface T1 can help the accumulated chips falling thereon to slide down under the action of gravity and further fall down to the chip receiving groove or plane at a lower position.

[0061] In the present invention, the rotary tool magazine can be a semi-rotary tool magazine, that is, a semi-umbrella tool magazine. Accordingly, the tool magazine body 11 can specifically include a base 111 and a semi-umbrella tool holder 112 rotatably arranged on the base 111. The semi-umbrella tool holder 112 has a semicircular side, and a door panel 113 is arranged on the semicircular side. The door panel 113 is adapted to the opening of the first tool changing port 1211. At the same time, the door panel 113 can rotate with the rotation of the semi-umbrella tool holder 112, so as to realize the change of the position of the door panel 113, and then realize the switching of the tool changing situation of the tool magazine. During the rotation process, the door panel 113 can enter the interior of the protective cover 121 through the first tool changing port 1211. Accordingly, the tool handle and the tool handle position on the tool magazine body 11 are exposed outside the first tool changing port 1211.

[0062] It is understandable that, when the tool is not being changed, the door panel 113 is shielded at the first tool changing port 1211, and the door panel 113 can form a relatively closed protective space with the protective cover 121, and accordingly, the tool handles on the tool magazine body 11 are all located in the protective cover 121 and protected. When the tool is being changed, the door panel 113 is located in its entirety or in part in the protective cover 121, and accordingly, the tool handle and / or tool handle position on the tool magazine body 11 are completely exposed outside the first tool changing port 1211, and the exposed tool handle or tool handle position can be used for the spindle to cooperate with the tool changing action.

[0063] It can be understood that the opening size of the second tool changing port 1311 is adapted to the radius of the tool handle or the front end of the spindle, so that during the tool changing process, the front end of the spindle or the tool handle thereon is supported to approach from the outside through the opening position of the second tool changing port 1311 toward the direction of the tool holder exposed outside the first tool changing port 1211 (that is, the Y-axis direction), thereby supporting the tool loading or unloading action during the tool changing process.

[0064] It is understandable that the rotary tool magazine may also be other forms of tool magazines having a tool magazine structure that allows the rotating body to be partially exposed after rotation, and the first protective component and the second protective component of the utility model may be installed to achieve double-layer protection for the tool magazine in different situations.

[0065] The utility model adopts a first protection component to provide protection for the tool handle and the tool on the tool magazine body, and adopts a second protection component to provide a shield protection for the part of the tool magazine body that is exposed with the corresponding tool handle or tool handle position when changing tools, thereby reducing the probability of accumulated chips on the spindle, spindle box, etc. directly falling onto the tool handle during tool changing, and can provide cleaning protection for the tool handle and tool handle position on the tool magazine body, which is beneficial to reducing the failure rate of tool changing.

[0066] See also Figure 3 , is a schematic diagram of the structure of a rotary tool magazine provided by the utility model in a specific application example. In this specific application example, the rotary tool magazine 1a can also include a tool magazine body (not shown), a first protection component 12a and a second protection component 13a, wherein the first protection component 12a is mainly used to provide protection for the tool handle on the tool magazine body, and the second protection component 13a is mainly used to provide protection for the tool handle that is partially exposed when changing tools. Figure 3 In the figure, the rotary tool magazine 1a is specifically a semi-umbrella type tool magazine.

[0067] The first protection assembly 12a may include a protection cover 121a, and the tool magazine body is accommodated in the protection cover 121a. The protection cover 121a has a front end portion Fa and a top end portion Ta, wherein the front end portion Fa may include a vertical front end face Fa1 and an oblique front end face Fa2, the oblique front end face Fa2 is arranged at an obtuse angle with the vertical front end face Fa1, and the oblique front end face Fa2 is located at the lower side of the vertical front end face Fa1.

[0068] A first tool changing opening 1211a is provided on the vertical front end surface Fa1, and the first tool changing opening 1211a is used for allowing the tool magazine body to be partially exposed outside the first tool changing opening 1211a during tool changing, so as to facilitate tool changing.

[0069] The second protection component 13a may include a protection plate 131a having a second tool change port 1311a. As mentioned above, the protection plate 131a is arranged on the inclined top surface Ta1 of the protection cover 121a. The protection plate 131a includes a plate edge 1312a extending in the width direction of the protection cover 121a (i.e., the X-axis direction in the figure). When changing the tool, the protection plate 131a covers the top side of the opening end of the first tool change port 1211a, and the second tool change port 1311a is located at a preset tool change position. In the figure, the opening direction of the second tool change port 1311a at this time is consistent with the opening direction of the first tool change port 1211a, so that the front end of the spindle for installing the tool handle can be placed, and a shield is formed for the space around the front end of the spindle, so that protection can also be provided for other partially exposed tool handles.

[0070] The tool magazine body includes a door panel 113a adapted to the first tool changing port 1211a. More specifically, the second protective assembly 13a in this specific application example also includes a first movable part 132a for driving the protective plate 131a to move along the first tool changing port 1211a (that is, the width direction of the first tool changing port 1211a in the figure).

[0071] When changing the tool, the first movable member 132a drives the protective plate 131a to move, so that the protective plate 131a covers the top side of the opening end of the first tool changing port 1211a, and the opening direction of the second tool changing port 1311a is consistent with the opening direction of the first tool changing port 1211a, so as to facilitate tool changing. In the case of non-tool changing or machine tool processing, in order to avoid affecting the processing space of the machine tool, the first movable member 132a drives the protective plate 131a to move to the farthest end of the machine tool working stroke.

[0072] In this specific application example, the second protective component 13a may also include a front plate 134a, which is connected to the protective plate 131a. A third tool change port 1341a is also provided on the front plate 134a, and the third tool change port 1341a is connected to the second tool change port 1311a. The third tool change port 1341a is used to support the front end of the spindle or the tool handle thereon to approach the direction of the tool holder exposed outside the first tool change port 1211a from the outside through the opening position of the second tool change port 1311a during the tool change process, thereby supporting the tool loading or unloading action during the tool change process. At the same time, the front plate 134a provided can also reduce the waste or dirt splashing from the side to a certain extent, thereby obtaining a better protective effect. Here, the front plate 134a can be integrally formed with the protective plate 131a, and in the case of non-tool change, the door plate 113a can be arranged parallel to the front plate 134a.

[0073] The opening of the first tool changing port 1211a faces the front plate 134a, that is, the front plate 134a at least partially blocks the front of the first tool changing port 1211a. There is an escape space V between the front plate 134a and the first tool changing port 1211a for part of the tool magazine body to be exposed outside the first tool changing port 1211a for tool changing.

[0074] In this specific application example, a first slider 133a is further provided on the top end Ta, and the first slider 133a is fixedly connected to the protective plate 131a. Similarly, a second slider (not shown) is further provided on the oblique front end surface Fa2, and the second slider is fixedly connected to the front plate 134a. In the figure, the top side of the front plate 134a is connected to the protective plate 131a, and the bottom side thereof is connected to the second slider.

[0075] Correspondingly, a first guide rod 136a and a second guide rod 137a which are arranged parallel to each other are also provided on the protective cover 121a, and the rod bodies of the first guide rod 136a and the second guide rod 137a extend in the width direction of the protective cover 121a, wherein the first guide rod 136a is specifically arranged on the top end portion Ta, and the second guide rod 137a can be arranged on the inclined front end surface Fa2.

[0076] The first slider 133a includes a first slide groove 1331a, which is clamped and slidably set on the rod body of the first guide rod 136a, so as to ensure that the protective plate 131a and the front plate 134a can move smoothly, which helps to improve the stability of tool change. Similarly, the second slider includes a second slide groove (not shown in the figure), which is clamped and slidably set on the rod body of the second guide rod 137a. Here, the notches of the first slide groove 1331a and the second slide groove are both set toward the back direction of the protective cover 121a (that is, the Y-axis direction in the figure, and away from the front plate).

[0077] Preferably, a cover plate (not shown) may be provided on the protective cover 121a to prevent the accumulated chips from falling directly onto the rod body of the first guide rod 136a. Accordingly, a plate gap (not shown) adapted to the thickness of the protective plate is reserved between the cover plate and the protective cover 121a, and the extension direction of the plate gap is consistent with the extension direction of the rod body of the first guide rod 136a. The second guide rod 137a is arranged below the front plate 134a, and the front plate 134a can form a shield protection for the rod body of the second guide rod 137a.

[0078] It can be understood that, as an alternative, the guide rod can be replaced by a guide rail for the corresponding slider to slide.

[0079] In this specific application example, a driving member 138a may be provided to drive the first movable member to move. The driving member 138a may be a cylinder, and the telescopic rod of the cylinder extends in the same direction as the width direction, that is, extends in the X-axis direction. The end of the telescopic rod of the cylinder may be connected to the first movable member. Accordingly, when the telescopic rod is extended and moved, the protective plate 131a may be driven to move in the X-axis direction to adapt to different tool changing positions.

[0080] The rotary tool magazine provided in this specific application example has the effect of the aforementioned basic structure in principle, and also achieves a better protection effect by providing a front plate 134a. At the same time, by providing a first movable member 132a to drive the protective plate 131a to move, the interference with other action mechanisms on the machining center can be reduced as much as possible, so that the rotary tool magazine can adapt to the installation space of more machining centers and has better versatility.

[0081] See also Figure 4 , which is a schematic diagram of the structure of the rotary tool magazine provided by the utility model in another specific application example. In this specific application example, the rotary tool magazine 1b includes a tool magazine body (not shown), a first protection component 12b and a second protection component 13b. Similarly, the first protection component 12b is mainly used to provide protection for the tool handle on the tool magazine body, and the second protection component 13b is mainly used to provide protection for the tool handle that is partially exposed when changing tools. Figure 4 In the figure, the rotary tool magazine 1b is specifically a semi-umbrella type tool magazine.

[0082] The first protection component 12b is similar to the above-mentioned specific application example, and includes a protection cover 12b. The tool magazine body is accommodated in the protection cover 121b, and the protection cover 121b has a front end Fb and a top end Tb. The front end Fb may include a vertical front end face Fb1 and an oblique front end face Fb2, the oblique front end face Fb2 is set at an obtuse angle with the vertical front end face Fb1, and the oblique front end face Fb2 is located at the lower side of the vertical front end face Fb1.

[0083] The second protection component 13b may include a protection plate 131b having a second tool change port 1311b, and the protection plate 131b is arranged at the top end Tb of the protection cover 121b (it may also be the top side of the front end Fb). The protection plate 131b includes a plate edge 1312b extending in the width direction of the protection cover 121b (i.e., the X-axis direction in the figure). When changing the tool, the protection plate 131b covers the top side of the opening end of the first tool change port 1211b, and the second tool change port 1311b is located at a preset tool change position. In the figure, the opening direction of the second tool change port 1311b is consistent with the opening direction of the first tool change port 1211b, so that the front end of the spindle for installing the tool handle can be placed, and a shield is formed for the space around the front end of the spindle, so that protection can also be provided for other partially exposed tool handles.

[0084] Compared with the above specific application example, the second protection component 13b includes a second movable member 132b for driving the protection plate 131b to flip relative to the inclined top surface Tb1.

[0085] When changing the tool, the second movable member 132b drives the protective plate 131b to flip, so that the protective plate 131b covers the top side of the opening end of the first tool changing port 1211b, and the opening direction of the second tool changing port 1311b is consistent with the opening direction of the first tool changing port 1211b. In the case of non-tool changing or machine tool processing, in order to avoid affecting the processing space of the machine tool, the second movable member 132b also drives the protective plate 131b to cover and / or be closely attached to the first tool changing port 1211b.

[0086] Specifically, the second protection assembly 13b may further include a hinge 133b and a driving member 134b, the protection plate 131b and the protection cover 121b are respectively connected to two relatively rotating ends of the hinge 133b, and the driving member 134b is arranged at the side end Lb1 of the protection cover 121b. In the figure, the hinge 133b is specifically arranged on the front end Fb and is located above the first blade changing port 1211b.

[0087] Here, the second movable member 132b may include a fixed block (not shown in the figure, which is a square block in the figure), which is fixedly arranged on the protective plate 131b, and a fixed shaft (not shown in the figure) is provided on the fixed block. The driving member 134b has a telescopic end, which is rotatably connected to the fixed shaft, thereby driving the protective plate 131b to flip up and down relative to the protective cover 121b.

[0088] The rotary tool magazine provided in this specific application example not only has the effect of the aforementioned basic structure, but also drives the protective plate 131b to flip by setting a second movable part 132b, which can also minimize the interference with other action mechanisms on the machining center, so that the rotary tool magazine can adapt to the installation space of more machining centers and has better versatility.

[0089] In the present invention, in addition to the above two specific application examples, the rotary tool magazine (not shown, refer to Figure 1 ), the protective plate can also be telescopically arranged on the top inner wall of the protective cover, and the extension direction of the protective plate is consistent with the direction of the first tool changing port. Correspondingly, the second protective component may also include a driving member for driving the protective plate to be extended and retracted. In the case of tool changing, the driving member drives the protective plate to extend so that the protective plate covers the first tool changing port. In the case of non-tool changing, the protective plate is in the protective cover and is located in the reserved telescopic gap formed by the top inner wall of the protective cover and the top edge of the door panel. The movements of the protective plate and the door panel are relatively independent, and a linkage structure may also be provided. The linkage structure can link the rotation movement of the rotating tool holder of the tool magazine body (such as the aforementioned semi-umbrella tool holder) with the telescopic movement of the protective plate. For example, a reversing transmission component may be provided to perform action linkage and motion reversal.

[0090] Specifically, a track may be provided on the top inner wall of the protective cover, and a matching track may be provided on the upper plate surface of the protective plate. The driving member is a telescopic cylinder, and its cylinder rod can drive the protective plate to be telescopic. In addition, in order to prevent accumulated debris from falling onto the matching track, a brush may be provided on the track to scrape the matching track during the telescopic process of the protective plate, which is conducive to ensuring the stability of the telescopic activity of the protective cover.

[0091] See also Figure 5 , which is a schematic diagram of the structure of a machining center equipped with the above rotary tool magazine for the utility model. The machining center 2 may include a bed 21, on which the above rotary tool magazine 1 is arranged. Specifically, the tool magazine body of the rotary tool magazine 1 is arranged on the bed 21, and the tool holder of the tool magazine body 11 is arranged on the bed 21. More specifically, the rotary tool magazine 1 is arranged at a side position of the bed 21 in the Y-axis direction. The rotary tool magazine 1 can reduce the tool change failure rate of the machining center 2 by arranging the first protection component 12 and the second protection component 13, which is conducive to the machining center 2 to perform machining operations stably and efficiently.

[0092] The machining center 2 further includes a column 22 and a crossbeam 23, wherein the crossbeam 23 is arranged on the column 22, specifically, the crossbeam 23 is arranged on two columns 22 to form a gantry structure. A spindle box 24 movable in the Y-axis direction is arranged on the crossbeam 23, and a spindle is arranged on the spindle box 24, so that the spindle and the tool handle on the front end of the spindle can be translated in the Y-axis direction under the drive of the spindle box 24. Of course, the spindle box 24 can also include a ram that can be extended and retracted in the Z-axis direction, and the spindle is arranged on the ram. Accordingly, the spindle and the tool handle on the front end of the spindle can also have the degree of freedom of movement in the Y-axis and Z-axis directions.

[0093] In the machining center 2 provided by the utility model, the bed 21 is also provided with an X-axis slide 211 and chip grooves 212 located on both sides of the X-axis slide 211, and the rotary tool magazine 2 is fixedly arranged on one side of the X-axis slide 211, and the chip groove 212 is located below the protective cover 121, so that the chips falling onto the protective cover 121 of the rotary tool magazine 2 can further fall directly onto the chip groove 212, which is convenient for the staff to clean the chips.

[0094] The rotary tool magazine cooperates with the spindle action of the machining center. Since the rotary tool magazine supports both the protection of the tool magazine body inside the tool magazine and the protection of other tool holders and / or tool holder positions during the tool changing process, it can reduce the failure rate of tool changing, help maintain the stability of tool changing and support the high efficiency of machining operations.
