Description

Technical Field

[0001] The present invention relates to the technical field of processing equipment, and in particular to a tool magazine for a machine tool and a machine tool. Background Art

[0002] Existing machine tools are generally equipped with a tool magazine, so that it is convenient to perform multiple machining operations by clamping a workpiece once. In some machine tools, the tool magazine is located behind the main shaft. When a tool change is required, the tool magazine moves to the front to cooperate with the main shaft for tool change.

[0003] However, in existing machine tools (such as the machine tool with the patent publication number CN 212946729 U), the tool magazine is generally a straight-line tool magazine. The straight-line tool magazine is in a layered form. When applied to a double-headed machine or even a multi-headed machine, the straight-line tool magazine occupies too much space, or the number of replaceable tools in the tool magazine is limited, which is not conducive to the development of the machine tool in the direction of compactness, nor is it conducive to increasing the number of tools in the tool magazine.

[0004] Therefore, how to improve the compactness of the tool magazine and the number of replaceable tools is an urgent problem to be solved. Summary of the Invention

[0005] The present invention provides a tool magazine for a machine tool and a machine tool, which can improve the compactness of the tool magazine and increase the number of replaceable tools.

[0006] In a first aspect of the present invention, a tool magazine for a machine tool is provided, including a mounting body and tool sleeves disposed on the outer periphery of the mounting body for clamping tools. The mounting body extends along the axial direction and has a rotation axis. A plurality of rows of tool sleeve mounting positions are provided on the outer periphery of the mounting body, and a plurality of tool sleeves arranged along the axial direction of the mounting body are provided on each row of the tool sleeve mounting positions;

[0008] In some feasible embodiments, at least 4 rows of the tool sleeve mounting positions are provided on the outer periphery of the mounting body, and at least 4 tool sleeves arranged along the axial direction of the mounting body are provided on each row of the tool sleeve mounting positions. In the tool preparation position state of the tool sleeve, the tool loading direction of the tool sleeve is in the up-down direction.

[0009] In some feasible embodiments, 6 rows of the tool sleeve mounting positions are provided on the outer periphery of the mounting body, and at least 8 tool sleeves arranged along the axial direction of the mounting body are provided on each row of the tool sleeve mounting positions. The number of tool sleeves on each row of the tool sleeve mounting positions is the same and corresponds one by one. The tool loading directions of the tool sleeves pass through the rotation axis of the mounting body, or the tool loading directions of the tool sleeves are perpendicular to the rotation axis of the mounting body.

[0010] In some feasible implementation solutions, the installation main body is provided with a central through hole extending along the rotation axis direction;

[0011] The installation main body forms a polygonal cavity or a cylindrical cavity, and the tool sleeve is installed on the tool sleeve installation position on the outer wall of the polygonal cavity or the cylindrical cavity.

[0012] In some feasible implementation solutions, a plurality of extension plates are provided on the outer wall of the installation main body, the tool sleeve installation position is provided on the extension plates, the plane where the extension plates are located passes through the rotation axis of the installation main body, or the plane where the extension plates are located is perpendicular to the rotation axis of the installation main body, and the tool loading direction of the tool sleeve is perpendicular to the plane where the extension plates are located.

[0013] In some feasible implementation solutions, it further includes a fixed frame having a first accommodation space, the installation main body is rotatably arranged in the first accommodation space along the horizontal direction through a connecting member, and the installation main body is arranged to be vertically liftable relative to the fixed frame.

[0014] In some feasible implementation solutions, it further includes an installation frame having a second accommodation space; the installation frame is vertically liftably arranged in the first accommodation space of the fixed frame, and the installation main body is rotatably arranged in the second accommodation space; a sliding mechanism and a driving component for driving the installation frame and the installation main body to slide vertically are provided between the installation frame and the fixed frame.

[0015] In some feasible implementation solutions, the vertical projection of the fixed frame is U-shaped, the fixed frame includes a first support frame and a second support frame arranged at intervals and a connecting frame connecting the first support frame and the second support frame, and the first support frame, the second support frame and the connecting frame enclose a first accommodation space for accommodating the installation frame and the installation main body;

[0016] The vertical projection of the installation frame is U-shaped, and the orientation of the U-shaped opening of the installation frame is the same as the orientation of the U-shaped opening of the fixed frame; the installation frame includes a mounting plate and two connecting plates vertically mounted on both sides of the mounting plate, and the mounting plate and the two connecting plates enclose a second accommodation space for accommodating the installation main body; both ends of the installation main body are rotatably connected to the two connecting plates respectively through connecting members; a driving mechanism for driving the installation main body to rotate is provided on one of the connecting plates.

[0017] The second aspect of the present invention provides a machine tool, including a base, a track and a workbench arranged above the base, and further including the machine tool tool magazine as described above, the rotation axis of the installation main body is horizontally arranged, and the installation main body can reciprocate vertically relative to the base.

[0018] In some feasible embodiments, it further includes a gantry, a tool changing mechanism, a main shaft, and a protective door. The gantry has a passage penetrating in the front-back direction of the base, and the rails are arranged in the passage; the machine tool tool magazine is arranged at the rear side of the gantry; there are multiple main shafts which are slidably arranged at the front side of the gantry; the tool changing mechanism is movably arranged on the rails on the base, and the tool changing mechanism can reciprocate between below the machine tool tool magazine and below the main shaft through the passage. Multiple pairs of tool changing clamps are arranged on the tool changing mechanism, and the number of pairs of tool changing clamps is the same as the number of main shafts. The number of tool sleeves arranged on each row of tool sleeve mounting positions is a multiple of the number of main shafts;

[0019] The protective door is vertically arranged between the machine tool tool magazine and the gantry in an openable and closable manner for shielding or opening the passage.

[0020] The above-mentioned machine tool tool magazine includes a mounting body and tool sleeves arranged on the outer periphery of the mounting body for clamping tools. The mounting body extends along the axial direction and has a rotation axis. Multiple rows of tool sleeve mounting positions are arranged on the outer periphery of the mounting body, and multiple tool sleeves arranged along the axial direction of the mounting body are arranged on each row of tool sleeve mounting positions; wherein, the mounting body can rotate around the rotation axis to drive a row of tool sleeves to be in the tool preparation position, so as to increase the number of tool sleeves clamped on the mounting body, and compared with a straight row type tool magazine, it can reduce the occupied space of the tool magazine in the plane, improve the compactness of the tool magazine and increase the number of replaceable tools.

[0021] In addition, during tool changing, only one row of tool sleeves on the mounting body in the machine tool tool magazine needs to be moved from the machine tool tool magazine to below the main shaft by the tool changing mechanism, and the other rows of tool sleeves in the tool magazine do not need to be moved. Therefore, it is not necessary to move the entire tool magazine to below the main shaft like a traditional straight row type tool magazine, so that multiple rows of tool sleeves that do not need to be replaced in the machine tool tool magazine are not contaminated by chips and cutting fluid, ensuring the cleanliness of multiple rows of tool sleeves in the tool magazine.

[0032] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0033] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality of" means two or more unless otherwise specifically defined.

[0034] In the present invention, unless otherwise clearly specified and defined, terms such as "mounted", "connected", "coupled", "fixed", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection; it may be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] For a clearer and more accurate understanding of the content of the present invention, it will be described in detail below with reference to the accompanying drawings. The accompanying drawings of the specification show examples of embodiments of the present invention, in which the same reference numerals represent the same elements. It can be understood that the scale shown in the accompanying drawings of the specification is not the actual implementation scale of the present invention, and it is only for illustrative purposes and not drawn according to the original size.

[0036] Please refer to Figure 1 , the present invention provides a machine tool tool magazine, which includes a mounting body 100 and tool sleeves 200 disposed on the outer periphery of the mounting body 100 for clamping tools.

[0037] Please refer to Figure 2 and 3 , in order to increase the number of tool sleeves 200 that can be mounted on the mounting body 100, thereby increasing the tool storage capacity of the mounting body 100 and making it more convenient for the spindle to replace tools for multi-process machining, the mounting body 100 extends axially and has a rotation axis L. A plurality of rows of tool sleeve mounting positions 101 are provided on the outer periphery of the mounting body 100, and a plurality of tool sleeves 200 arranged axially along the mounting body 100 are provided on each row of the tool sleeve mounting positions 101. Each tool sleeve 200 is used for clamping a tool; compared with a straight-row tool magazine, the mounting body 100 can save space in the plane and increase the tool storage capacity.

[0038] Please refer to Figure 2 , 3 and 4, the structural relationship between the mounting body 100 and the tool sleeve 200 will be specifically described below. At least 4 rows of the tool sleeve mounting positions 101 are provided on the outer periphery of the mounting body 100, and at least 4 tool sleeves 200 arranged axially along the mounting body 100 are provided on each row of the tool sleeve mounting positions 101. In the standby tool position B state of the tool sleeve 200, the tool loading direction of the tool sleeve 200 is the up and down direction.

[0039] To facilitate the identification of which set of tool holders 200 on the mounting body 100 holds the tool to be replaced. Among them, the mounting body 100 can rotate around the rotation axis L to drive a row of the tool holders 200 to be in the tool preparation position B. The attitude of a set of tool holders 200 in the tool preparation position B is that the tool loading direction is in the vertical up and down position. In this way, when the tool loading direction of a set of tool holders 200 is in the vertical up and down position, this set of tool holders 200 is the tool to be replaced. And the tool holders 200 in the mounting body 100 that are not in the tool preparation position B are still protected inside the mounting body 100 and will not be moved out of the mounting body 100 to the outside, avoiding the contamination of the tool holders 200 not in the tool preparation position B by cutting fluid and chips, and ensuring the cleanliness of the tool holders 200 in the tool magazine that are not in the tool preparation position B. In this embodiment, the tool preparation position B is the position where the tool loading direction of the tool holder 200 is in the vertical up and down position (specifically refer to Figure 3 the markings of the up and down directions in

[0040] To increase the number of tools stored on the mounting body 100, so that the machine tool tool magazine can be applicable to multi-channel processing machines or enable the spindle to process more different processes. Preferably, the outer periphery of the mounting body 100 has 6 rows of tool holder mounting positions 101, and at least 8 tool holders 200 arranged along the axial direction of the mounting body 100 are provided on each row of the tool holder mounting positions 101. The number of tool holders 200 on each row of the tool holder mounting positions 101 is the same and corresponds one by one. The tool loading direction of each tool holder 200 passes through the rotation axis L of the mounting body 100, or the tool loading direction of each tool holder 200 is perpendicular to the rotation axis L of the mounting body 100. It can be understood that when the tool loading direction of each tool holder 200 passes through the rotation axis L of the mounting body 100, the tool holder 200 is easily installed on the mounting body 100, reducing the time for assembling the machine tool tool magazine and increasing the production capacity of the machine tool tool magazine. When the tool loading direction of each tool holder 200 is perpendicular to the rotation axis L of the mounting body 100, there is an included angle between the center line of the tool holder 200, the connecting line between the center of gravity of the tool holder 200 and the center of the mounting body 100, so that the center of gravity of the tool holder 200 is closer to the rotation axis L of the mounting body 100, thereby further reducing the occupied space of the machine tool tool magazine and further improving the compactness of the machine tool tool magazine.

[0041] Please refer to Figure 3 、 4, 5, and 6, in order to reduce the weight of the mounting body 100 and increase the number of tool holders 200 mounted on the mounting body 100 as much as possible, the mounting body 100 is provided with a central through hole 102 extending along the direction of the rotation axis L; the mounting body 100 forms a polygonal cavity or a cylindrical cavity, and the tool holder 200 is mounted on the tool holder mounting position 101 on the outer wall of the polygonal cavity or the cylindrical cavity; when the mounting body 100 forms a polygonal cavity, the mounting body 100 has at least three outer peripheral walls connected end to end, and several groups of tool holders 200 are respectively mounted on at least three outer peripheral walls, and each tool holder 200 is perpendicular to the corresponding outer peripheral wall. The outer shape of the mounting body 100 is a prism, which can be a triangular prism, a quadrangular prism, a pentagonal prism, a hexagonal prism, or even a prism with more outer walls, and can be selected according to actual situations.

[0042] Please refer to Figure 5 and 6 , in some other embodiments, in order to reduce the size of the combination of the mounting body 100 and the tool holder 200 in the direction perpendicular to the rotation axis L, a plurality of extension plates 110 are provided on the outer wall of the mounting body 100, and the tool holder mounting position 101 is provided on the extension plates 110. The tool holder mounting position 101 is provided on the first surface where the extension plate 110 is flush with the outer peripheral wall of the mounting body 100. There is an included angle between the second surface of the mounting body 100 and another outer peripheral wall of the mounting body 100, so that the mounting space of the first surface of the extension plate 110 is larger than that of the second surface, which increases the interval between the tool holder 200 in the standby tool position B and another adjacent tool holder 200, facilitating the tool change operation. The plane where the extension plate 110 is located passes through the rotation axis L of the mounting body 100, or the plane where the extension plate 110 is located is perpendicular to the rotation axis L of the mounting body 100, and the tool loading direction of the tool holder 200 is perpendicular to the plane where the extension plate 110 is located. This avoids the phenomenon that the straight lines where several groups of tool holders 200 are located coincide with a certain radial straight line of the mounting body 100, resulting in an excessive radial dimension of the machine tool tool magazine, increases the number of tools stored in the machine tool tool magazine, and improves the compactness of the machine tool tool magazine.

[0043] Please refer to Figure 1 and 2In order to facilitate the rotation of the machine tool magazine and the lifting and lowering of the machine tool magazine relative to the machine tool base 800, the machine tool magazine also includes a fixed frame 300 with a first receiving space S1, the installation body 100 is rotatably arranged in the first receiving space S1 along the horizontal direction through the connecting piece 103, and the installation body 100 is vertically liftable relative to the fixed frame 300. The machine tool magazine also includes a mounting frame 400 with a second receiving space S2; the mounting frame 400 is vertically liftable in the first receiving space S1 of the fixed frame 300, and the mounting body 100 is rotatably arranged in the second receiving space S2; a sliding mechanism 500 and a driving assembly 600 are arranged between the mounting frame 400 and the fixed frame 300 to drive the mounting frame 400 and the mounting body 100 to slide vertically. The driving assembly 600 is used to drive the mounting frame 400 and the mounting body 100 to reciprocate vertically relative to the fixing frame 300. The sliding mechanism 500 is used to reduce the friction between the mounting frame 400 and the fixing frame 300 and has a guiding function.

[0044] Please see Figure 2 The driving assembly 600 includes a motor 610, a screw rod 620 and a nut 630. The motor 610 is transmission-connected to the nut 630 and the motor 610 and the screw rod 620 are installed on the fixing frame 300. The nut 630 is threadedly matched with the screw rod 620 and the nut 630 is installed on the mounting frame 400, so that the mounting frame 400 and the mounting body 100 can slide vertically relative to the fixing frame 300.

[0045] Please see Figure 1 and 2 In order to ensure that the mounting frame 400 moves vertically in a straight line relative to the fixed frame 300, the machine tool magazine also includes a guide member 710 and a guide matching member 720. The mounting frame 400 is matched with the fixed frame 300 along the vertical guidance through the guide member 710 and the guide matching member 720; the guide member 710 is arranged on one of the fixed frame 300 and the mounting frame 400, and the guide matching member 720 is arranged on the other of the fixed frame 300 and the mounting frame 400, so as to ensure that the mounting frame 400 moves vertically in a straight line relative to the fixed frame 300, thereby avoiding displacement of the mounting frame 400 during movement.

[0046] Please see Figure 2, in order to reduce weight and ensure the supporting strength, the projection of the fixing frame 300 along the vertical direction is U-shaped. The fixing frame 300 includes a first support frame 310 and a second support frame 320 arranged at intervals and a connecting frame 330 connecting the first support frame 310 and the second support frame 320. The first support frame 310, the second support frame 320 and the connecting frame 330 enclose a first receiving space S1 for receiving the mounting frame 400 and the mounting body 100. The outer contour of the first support frame 310 can be formed by welding multiple pipes, which can not only ensure the connection strength but also reduce the weight. It can be understood that reinforcing ribs can be arranged inside the first support frame 310 to improve the structural strength and facilitate the installation of the guide member 710 or the guide fitting 720 to the first support frame 310 through the reinforcing ribs. The outer contour of the second support frame 320 can be formed by welding multiple pipes, which can not only ensure the connection strength but also reduce the weight. The outer contour of the connecting frame 330 can be formed by welding multiple pipes, which can not only ensure the connection strength but also reduce the weight. The bottoms and the front sides of the first support frame 310 and the second support frame 320 are both connected to the machine tool, thereby improving the connection strength between the fixing frame 300 and the machine tool.

[0047] Please refer to Figure 2 , the projection of the mounting frame 400 along the vertical direction is U-shaped, and the orientation of the U-shaped opening of the mounting frame 400 is the same as that of the U-shaped opening of the fixing frame 300; the mounting frame 400 includes a mounting plate 410 and two connecting plates 420 vertically mounted on both sides of the mounting plate 410. The mounting plate 410 and the two connecting plates 420 enclose a second receiving space S2 for receiving the mounting body 100; both ends of the mounting body 100 are rotatably connected to the two connecting plates 420 through connectors 103 respectively; a driving mechanism 1200 for driving the mounting body 100 to rotate is provided on one of the connecting plates 420. The driving mechanism 1200 is mounted on one of the connecting plates 420. The driving mechanism 1200 includes a driving member and a transmission member. The connector 103 is in transmission connection with the transmission member. For example, the connector 103 can be in transmission connection with the transmission member through a rotating shaft and a driven wheel, and the transmission member can be a belt with gears.

[0048] Please refer to Figure 1 and 2 , the specific structure of the sliding mechanism 500 will be introduced below. The sliding mechanism 500 includes at least two slide rails 510 and at least two groups of sliders 520 slidably engaged with the at least two slide rails 510. The at least two slide rails 510 extend vertically and are fixedly installed on the connecting frame 330 at intervals. The at least two groups of sliders 520 are fixedly installed on the mounting plate 410.

[0049] The above-mentioned machine tool tool magazine includes an installation main body 100 and tool sleeves 200 arranged on the outer periphery of the installation main body 100 for clamping tools. The installation main body 100 extends along the axial direction and has a rotation axis L. A plurality of rows of tool sleeve installation positions 101 are provided on the outer periphery of the installation main body 100, and a plurality of tool sleeves 200 arranged along the axial direction of the installation main body 100 are provided on each row of the tool sleeve installation positions 101. Among them, the installation main body 100 can rotate around the rotation axis L to drive a row of the tool sleeves 200 to be in the tool preparation position B, so that the number of tool sleeves 200 clamped on the installation main body 100 can be increased. Compared with the straight row type tool magazine, the occupied space of the tool magazine in the plane can be reduced, the compactness of the tool magazine can be improved, and the number of replaceable tools can be increased.

[0050] In addition, when changing tools, only a row of the tool sleeves 200 on the installation main body 100 in the machine tool tool magazine needs to be moved from the machine tool tool magazine to below the main shaft through the tool changing mechanism 1000, and the other rows of the tool sleeves 200 in the tool magazine do not need to be moved. Therefore, it is not necessary to move the entire tool magazine below the main shaft like a traditional straight row type tool magazine, so that the multiple rows of the tool sleeves 200 that do not need to be replaced in the machine tool tool magazine are not contaminated by chips and cutting fluid, ensuring the cleanliness of the multiple rows of the tool sleeves 200 in the tool magazine.

[0051] Please refer to Figure 1 , the present invention also provides a machine tool, including a base 800, a rail 1300 and a workbench arranged above the base 800, and further including the above-mentioned machine tool tool magazine. The rotation axis L of the installation main body 100 is horizontally arranged, and the installation main body 100 can reciprocate vertically relative to the base 800.

[0052] Please refer to Figure 1 and 2, The following describes how the machine tool realizes the tool change operation. The machine tool further includes a gantry 900, a tool change mechanism 1000, a spindle and a protective door 1100. The gantry 900 has a channel T running through in the front-back direction of the base 800, and the track 1300 is arranged in the channel T; the tool magazine of the machine tool is arranged at the rear side of the gantry 900; the spindle is slidably arranged at the front side of the gantry 900; the tool change mechanism 1000 is movably arranged on the track 1300 on the base 800. The tool change mechanism 1000 can reciprocate between below the tool magazine and below the spindle through the channel T. Multiple pairs of tool change clamps 1010 are arranged on the tool change mechanism 1000. The number of pairs of tool change clamps 1010 is the same as the number of spindles. The number of tool sleeves 200 arranged on each row of tool sleeve mounting positions 101 is a multiple of the number of spindles. It can be understood that the spindle clamping one kind of tool can perform the processing of one process. When the spindle realizes clamping two kinds of tools by changing the tool, only by clamping the workpiece once can the processing of two processes be carried out. Therefore, the number of spindles corresponds to the number of tool sleeves 200. The number of spindles determines how many workpieces can be processed simultaneously, realizing the processing of a multi-spindle machine. The number of tools can be determined according to how many processing processes are required by the spindle, and then the total number of tools can be determined according to the number of spindles. The number of tool sleeves 200 is the same as the total number of tools.

[0053] Please refer to Figure 1 and 2 , In order to prevent the chips and cutting fluid generated during the machining of the spindle from splashing into the tool magazine and avoid contaminating the tool magazine with the cutting fluid and chips, the protective door 1100 is vertically arranged between the tool magazine of the machine tool and the gantry 900 in an openable and closable manner to block or open the channel T. The protective door 1100 is vertically arranged between the tool magazine of the machine tool and the gantry 900. The protective door 1100 can move up and down vertically. When the protective door 1100 moves vertically to the lower part close to the base 800, it blocks the channel T. When the protective door 1100 moves vertically to the upper part away from the base 800, it opens the channel T.

[0054] The present invention also provides a method for using a machine tool. The machine tool is the above-mentioned machine tool. The tool change method of the machine tool includes:

[0055] Step 10: Drive the tool changing mechanism 1000 of the machine tool to move below the tool magazine; it can be understood that when tool changing is required, the tool changing mechanism 1000 needs to move below the tool magazine, and the spindle can be in the machining state or the stopped state. When it is necessary to shorten the tool changing time to improve the tool changing efficiency, the tool changing mechanism 1000 can move below the tool magazine in advance when the spindle is in the machining state, so as to reduce the tool taking time of the tool changing mechanism 1000. In this way, when the spindle is in the stopped state, the tool changing mechanism 1000 that has taken the tool can cooperate with the spindle in time, and the spindle does not need to wait.

[0056] Step 30: Drive the installation body 100 of the machine tool tool magazine to rotate so that the tool to be replaced moves to the tool preparation position B; in this embodiment, the tool preparation position B is the position where the loading direction of the tool sleeve 200 is vertically up and down. That is to say, when the tool sleeve 200 rotates on the installation body 100 until the loading direction is vertically up and down, the tool clamped on the tool sleeve 200 is the tool to be replaced.

[0057] Step 50: The tool changing mechanism 1000 removes the tool to be replaced at the tool preparation position B from the tool magazine; the tool changing mechanism 1000 clamps the tool to be replaced on the tool sleeve 200. In this embodiment, a plurality of pairs of tool changing clamps 1010 are provided on the tool changing mechanism 1000, and the number of pairs of the tool changing clamps 1010 is the same as the number of spindles. The number of tool sleeves 200 provided on each row of the tool sleeve installation positions 101 is a multiple of the number of spindles. It can be understood that one tool clamped by the spindle can be used for machining one process. When the spindle can clamp two tools by changing tools, only one workpiece needs to be clamped once to perform two processes of machining. Therefore, the number of spindles corresponds to the number of tool sleeves 200. The number of workpieces that can be machined simultaneously is equal to the number of spindles, realizing the machining of a multi-spindle machine. The number of tools can be determined according to the number of machining processes required by the spindle, and then the total number of tools can be determined according to the number of spindles. The number of tool sleeves 200 is equal to the total number of tools. The tool changing clamp 1010 has two card slots. One card slot on the tool changing clamp 1010 clamps the tool clamped on the tool sleeve 200 at the tool preparation position B on the installation body 100, and the tool to be replaced moves from the tool sleeve 200 at the tool preparation position B to the tool changing mechanism 1000.

[0058] Step 70: The tool changing mechanism 1000 drives the tool to be replaced to move below the spindle, and assembles the tool to be replaced from the tool changing mechanism 1000 onto the spindle. Another card slot on the tool changing mechanism 1000 is idle. If there is a tool on the spindle, then the other idle card slot on the tool changing mechanism 1000 can unload the tool currently being processed on the spindle, and then rotate the tool changing clamp 1010 of the tool changing mechanism 1000 to clamp the tool to be replaced onto the spindle. If there is no tool on the spindle, then the card slot on the tool changing mechanism 1000 that holds the tool to be replaced moves below the spindle, and the spindle moves further down to enable the spindle to hold the tool to be replaced, that is, the spindle holds the new tool for processing another operation.
