For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0036] To make the content of the present utility model clearer and more accurate, it will be described in detail below with reference to the accompanying drawings. The drawings in the specification show examples of the embodiments of the present utility model, where the same reference numerals represent the same elements. It can be understood that the scale shown in the drawings of the specification is not the actual scale of the implementation of the present utility model, and it is only for illustrative purposes and not drawn according to the original size.
[0037] Please refer to Figure 2 and 3 , the present utility model provides a tool magazine, which includes a protective cover 100 and a blowing assembly 200. Among them, the protective cover 100 includes a side portion 103. The x-axis represents the horizontal direction, that is, the direction perpendicular to the side portion 103 of the protective cover 100, the y-axis represents the longitudinal direction, and the z-axis represents the vertical direction.
[0038] The protective cover 100 is used to protect the components inside the protective cover 100 and prevent the cutting fluid and chips outside the protective cover 100 from contaminating the components inside the protective cover 100. In this embodiment, the components inside the protective cover 100 include a tool disc 300, cutting tools, and a rotating assembly that drives the tool changing arm 400 to rotate. A tool changing opening 101 is provided on the protective cover 100; in this embodiment, the protective cover 100 is generally in the shape of a cuboid, and a tool changing opening 101 is provided at the bottom 102 of the protective cover 100.
[0039] Please refer to Figure 2, the air blowing assembly 200 is arranged on the protective cover 100, the air supply port of the air blowing assembly 200 faces the outside of the protective cover 100, and the air supply port of the air blowing assembly 200 can form an air curtain that separates the outside of the protective cover 100 from the tool changing port 101. At least part of the air curtain is located outside the protective cover 100. It can be understood that the air blowing assembly 200 can be arranged inside or outside the protective cover 100. When the air blowing assembly 200 is arranged inside the protective cover 100, a small part of the air curtain is located inside the protective cover 100, and most of the air curtain is located outside the protective cover 100; when the air blowing assembly 200 is arranged outside the protective cover 100, all of the air curtain is located outside the protective cover 100, so that the tool changing port 101 of the protective cover 100 is separated from the outside of the protective cover 100. In this way, the chips outside the protective cover 100 are blocked from entering the protective cover 100 through the tool changing port 101, ensuring the cleanliness inside the protective cover 100 and not affecting the normal tool changing operation of the tool disc 300 inside the protective cover 100.
[0040] Please refer to Figure 2 , for example, the air blowing assembly 200 is connected to the bottom 102 of the protective cover 100, the air blowing assembly 200 is arranged adjacent to the tool changing port 101, and the orientation of the air supply port p is parallel to or has a first included angle with the plane where the tool changing port 101 is located. Among them, the first included angle is an acute angle. When the orientation of the air supply port p is parallel to the plane where the tool changing port 101 is located, when the air supply port p starts to supply air, an air curtain parallel to the plane where the tool changing port 101 is located will be formed below the tool changing port 101. When a tool handle enters the tool changing port 101 from below the tool changing port 101, the chips on the tool handle will be blown away by the air curtain, preventing the chips from entering the inside of the protective cover 100. In some other embodiments, when there is a first included angle between the orientation of the air supply port p and the plane where the tool changing port 101 is located, there is a first included angle between the orientation of the air supply port of the air blowing assembly 200 and the plane where the tool changing port 101 is located, and the range of the first included angle is an acute angle. Specifically, the orientation of the air supply port p can also have an inclination angle with the plane where the tool changing port 101 is located. The air supply port p can be inclined towards the bottom wall of the protective cover 100, and the inclination angle is less than 15 degrees. The air curtain formed by the air supply port p will blow onto the bottom wall of the protective cover 100, but it can also play a role in preventing chips from entering the inside of the protective cover 100. In addition, the air supply port p can also be inclined away from the bottom wall of the protective cover 100, and the inclination angle is less than 15 degrees. In this way, the air curtain formed by the air supply port p will not blow onto the protective cover 100, and can still separate the outside of the protective cover 100 from the tool changing port 101.
[0041] Please refer to Figure 2 and 3, the tool magazine further includes a tool disc 300 located within the protective cover 100. The tool disc 300 is rotatably disposed on the side portion 103 of the protective cover 100. The protective cover 100 includes a bottom plate 110 at the bottom 102, and the tool change opening 101 is formed on the bottom plate 110; the tool disc 300 includes a disc body 310 and a tool mounting portion 320 provided on the periphery of the disc body 310. The tool mounting portion 320 has a tool storage state perpendicular to the disc body 310 and located within the protective cover 100, and the tool mounting portion 320 also has a tool loading and changing state parallel to the disc body 310 and extending out of the protective cover 100 through the tool change opening 101; the projection of the tool mounting portion 320 on the horizontal plane is at least partially located within the tool change opening 101. The tool mounting portion 320 is rotatably mounted on the periphery of the tool disc 310 on the side away from the side portion 103. The outer diameter of the ring where the tool mounting portion 320 is located is larger than the outer diameter of the tool disc 310, and the inner diameter of the ring where the tool mounting portion 320 is located is smaller than the outer diameter of the tool disc 310. The tool change opening 101 is located at the bottom 102 of the protective cover 100.
[0042] Please refer to Figure 3 , in order to ensure that the protective cover 100 protects the tool disc 300, and at the same time can ensure that the tool magazine is as compact as possible and avoid excessive space occupation, the bottom plate 110 has a step. The step includes a high-level step surface 111 at a high position, a low-level step surface 112 at a low position, and a connecting surface 113 connecting the high-level step surface 111 and the low-level step surface 112. The tool change opening 101 penetrates from the plate body where the low-level step surface 112 is located to the plate body where the high-level step surface 111 is located; the air blowing assembly 200 corresponds to the position of the low-level step surface 112. The air curtain formed by the air blowing assembly 200 is at least partially located at the tool change opening 101 of the plate body where the low-level step surface 112 is located. Since the size of the tool disc 300 increases from the head to the tail, it can be understood that the head of the tool disc 300 is the position close to the side portion 103, and the tail of the tool disc 300 is the position away from the side portion 103. The cross-sectional dimension of the bottom 102 of the protective cover 100 also increases from the high-level step surface 111 to the low-level step surface 112 in the vertical direction. Therefore, the bottom 102 of the protective cover 100 has a stepped structure corresponding to the structure of the tool disc 300 in the vertical direction. The high-level step surface 111 is disposed below the disc body 310, the low-level step surface 112 is disposed below the tool mounting portion 320, the tool change opening 101 includes a first tool change opening 1011 located on the high-level step surface 111 and a second tool change opening 1012 located on the low-level step surface 112. The air curtain can at least isolate the second tool change opening 1012 from the outside of the protective cover 100. The tool change opening 101 extends from the high-level step surface 111 to the low-level step surface 112. The first tool change opening 1011 is used for the tool mounting portion 320 to rotate from within the protective cover 100 to outside the protective cover 100, and the second tool change opening 1012 is used for the tool to rotate from within the protective cover 100 to outside the protective cover 100.
[0043] Please refer to Figure 2 Figure 2 , a tool changing arm 400 is provided on the front side of the high-level step surface 111. The tool changing arm 400 rotates to the first tool changing port 1011 to grasp the tool shank of the tool, and performs a tool changing action. It can be understood that the tool changing arm 400 can rotate. When the tool changing arm 400 rotates to the first tool changing port 1011 at the rear side of the high-level step surface 111, the tool shank in the tool disc 300 will rotate out from the first tool changing port 1011 at the rear side of the high-level step surface 111, and at the same time, the tool in the tool disc 300 rotates out from the second tool changing port 1012 on the low-level step surface 112.
[0044] Please refer to Figure 3 and 4 4 , in order to facilitate the air supply port of the air blowing assembly 200 to form an air curtain that separates the outside of the protective cover 100 from the first tool changing port 1011 and the second tool changing port 1012. In this embodiment, the air blowing assembly 200 includes a connecting block 210 and at least two air supply members 220; an air supply channel c is provided in the connecting block 210, the head end of each air supply member 220 is communicated with the air supply channel c, and the tail end of each air supply member 220 has a flat air supply port; and / or the air blowing assembly 200 includes a connecting block 210 and at least two air supply members 220. The connecting block 210 is L-shaped. The connecting block 210 includes a first sub-connecting block 211 and a second sub-connecting block 212. The length of the first sub-connecting block 211 is longer than that of the second sub-connecting block 212. A first connecting portion 2111 for connecting with the protective cover 100 is provided on the first sub-connecting block 211, and a second connecting portion 2121 for connecting with the protective cover 100 is provided on the second sub-connecting block 212. At least one air supply member 220 is arranged below the high-level step surface 111 through the second sub-connecting block 212 and can separate the part of the tool changing port 101 located on the high-level step surface 111 (i.e., the first tool changing port 1011) from the outside of the protective cover 100. In this embodiment, the first air supply member 2201 is arranged below the high-level step surface 111, and the second air supply member 2202 is arranged below the low-level step surface 112. The air blowing assembly 200 includes a first air supply member 2201 on the high-level step surface 111 and a second air supply member 2202 on the low-level step surface 112. The air supply port of the second air supply member 2202 is parallel to the plane where the high-level step surface 111 is located. The plane where the air supply port of the first air supply member 2201 is located and the plane where the air supply port of the second air supply member 2202 is located have a second included angle. For example, the second included angle between the plane where the air supply port of the first air supply member 2201 is located and the plane where the air supply port of the second air supply member 2202 is located is an obtuse angle. In this way, the chips below the first tool changing port 1011 can be isolated by the first air supply member 2201, and the chip removal of the high-position first tool changing port 1011 can be improved.
[0045] Please refer to Figure 4 , in order to facilitate the adjustment of the orientation of the air outlet of each air supply member 220, each of the air supply members 220 includes a mounting base 221, a universal joint 222, and an air outlet nozzle 223. The head end of the mounting base 221 is connected to the connecting block 210 and is in communication with the air supply passage c. The air outlet nozzle 223 is in communication with the tail end of the mounting base 221 through the universal joint 222. The end of the air outlet nozzle 223 away from the universal joint 222 is flat. By providing the universal joint 222, the bending angle and direction of the universal joint 222 can be adjusted to adjust the orientation of the air outlet relative to the tool change opening 101; and / or the air supply passage c of the connecting block 210 is used to communicate with a pressure air source. When the chips of the machine tool are relatively large or dense, the air curtain requires a greater blowing force. The connecting block 210 can be connected to a higher pressure (i.e., higher Mpa) air source, which can improve the cleaning efficiency and prevent some chips from entering the protective cover 100.
[0046] For the above tool magazine, by providing the air blowing assembly 200, the air blowing assembly 200 is connected to the protective cover 100. The air outlet of the air blowing assembly 200 faces the outside of the protective cover 100. The air outlet of the air blowing assembly 200 can form an air curtain that separates the outside of the protective cover 100 from the tool change opening 101. At least part of the air curtain is located outside the protective cover 100, thereby preventing chips outside the protective cover 100 from entering the protective cover 100 through the tool change opening 101, and reducing the risk of chips adhering to the tool shank and scratching or damaging the tool shank or the tool holder of the tool magazine.
[0047] Please refer to Figure 5 , in another embodiment, in order to reduce the occupied space of the air blowing assembly 200, the air blowing assembly 200 is arranged inside the protective cover 100; the included angle range between the air outlet of the air blowing assembly 200 and the plane where the tool change opening 101 is located is 7 - 15 degrees. In this way, the air outlet can also form an air curtain that separates the outside of the protective cover 100 from the tool change opening 101. And / or the protective cover 100 includes a first enclosing portion 104 and a second enclosing portion 105 that enclose to form the tool change opening 101. The extending directions of the first enclosing portion 104 and the second enclosing portion 105 are both perpendicular to the side portion 103 of the protective cover 100. The first enclosing portion 104 and the second enclosing portion 105 are arranged opposite to each other. The air blowing assembly 200 is located inside the protective cover 100 and is installed on the first enclosing portion 104 or the second enclosing portion 105. There is a third included angle between the air outlet of the air blowing assembly 200 and the first enclosing portion 104. The third included angle is an acute angle, and the air outlet of the air blowing assembly 200 faces outside the protective cover 100.
[0048] Please refer to Figure 6, in the third embodiment, the air blowing assembly 200 includes an air supply block 201. An air supply gap q is provided on one side of the air supply block 201. The end of the air supply gap q forms an air supply port p. The extending direction of the air supply gap q corresponds to the extending direction of the cutting edge 101. The extending direction of the cutting edge 101 is from the high-level step surface 111, through the connecting surface 113, and extends to the low-level step surface 112. The extending direction of the air supply gap q is also set corresponding to the extending direction of the cutting edge 101.
[0049] The air supply block 201 includes a first air supply block 2011 and a second air supply block 2012. The first air supply block 2011 and the first cutting edge 1011 are spaced apart along the direction perpendicular to the side portion 103. The second air supply block 2012 and the second cutting edge 1012 are spaced apart along the direction perpendicular to the side portion 103. The part of the cutting edge 101 located on the connecting surface 113 is the third cutting edge 1013. The first cutting edge 1011 is communicated with the second cutting edge 1012 through the third cutting edge 1013. Specifically, the head of the third cutting edge 1013 in the vertical direction is communicated with the first cutting edge 1011, and the bottom 102 of the third cutting edge 1013 in the vertical direction is communicated with the second cutting edge 1012. The part where the first air supply block 2011 and the second air supply block 2012 are connected is spaced apart from the third cutting edge 1013 along the direction perpendicular to the side portion 103. The length of the first air supply block 2011 in the extending direction corresponds to the length of the first cutting edge 1011 in the direction perpendicular to the side portion 103. The length of the second air supply block 2012 in the extending direction corresponds to the length of the second cutting edge 1012 in the direction perpendicular to the side portion 103. For example, the first air supply block 2011 and the second air supply block 2012 are strip-shaped. The tail of the first air supply block 2011 is stacked on the head of the second air supply block 2012, so that the shape of the air supply block 201 corresponds to the shape of the bottom 102 of the protective cover 100, and at the same time, the extending direction of the air supply gap q corresponds to the extending direction of the cutting edge 101, which is convenient for installing the air supply block 201 to the protective cover 100 and for isolating the cutting edge 101 from the outside of the protective cover 100 through the air supply gap q.
[0050] The air supply gap q includes a first-stage gap q1, a second-stage gap q2, and a third-stage gap q3 that are interconnected. The opening gaps of the first-stage gap q1, the second-stage gap q2, and the third-stage gap q3 are all between 2 and 4 mm. The first-stage gap q1 is provided in the first air supply block 2011, the second-stage gap q2 is provided between the first air supply block 2011 and the second air supply block 2012, and the third-stage gap q3 is provided in the second air supply block 2012. When the air supply block 201 is ventilated, the air curtain formed by the ventilation of the first-stage gap q1 separates the first tool-changing edge 1011 from the outside of the protective cover 100. The air curtain formed by the ventilation of the second-stage gap q2 separates the third tool-changing edge 1013 from the outside of the protective cover 100. The air curtain formed by the ventilation of the third-stage gap q3 separates the second tool-changing edge 1012 from the outside of the protective cover 100. Thus, the entire tool-changing edge 101 can be separated from the outside of the protective cover 100, preventing chips and cutting fluid from entering the protective cover 100. The plane where the air outlet of the air supply gap q is located can be parallel to the plane where the tool-changing edge 101 is located, or the plane where the air outlet of the air supply gap q can be inclined. For example, the plane where the air outlet of the air supply gap q rotates by a third acute angle towards the bottom 102 of the protective cover 100. Another example is that the plane where the air outlet of the air supply gap q rotates by a third acute angle away from the bottom 102 of the protective cover 100. It can be understood that the included angle range of the third acute angle is 1-15°.
