[0002] At present, the tool changing arm is a key component in CNC machine tools. It can realize the automatic replacement of machine tool tools and improve the processing efficiency and accuracy of machine tools.

[0003] In the prior art, the tool on the tool changing arm is usually locked and fixed by pushing the locking piece with a spring, that is, during the movement of the tool changing arm, the elastic force of the spring is used to lock and fix the tool on the tool changing arm to prevent the tool from shaking or even falling off the tool changing arm during the replacement process.

[0004] However, the above locking and fixing methods are limited by the influence of the spring. On the one hand, the elastic force of the spring will inevitably decrease during continuous use, and the locking and fixing reliability will also decrease, which will cause the tool to fall off or fling off during the replacement process; on the other hand, during the machine tool processing, iron wire or fine debris may also splash into the spring, causing the spring to become stuck, and manual maintenance is required at this time.

[0029] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0031] In order to solve the problem of poor locking stability of the tool on the tool changing arm of a machine tool in the prior art, the present application provides a tool changing device and a processing equipment having the same.

[0032] like Figures 1 to 6As shown, the tool changing device is rotatably arranged on the main body of the processing equipment and includes a mounting structure 10 and a locking assembly 20. The mounting structure 10 has a housing portion 11 and an escape opening 12 connected to the housing portion 11. The housing portion 11 is used to accommodate the tool 1, and the escape opening 12 is used to allow the tool 1 to move into the housing portion 11 during the rotation of the tool changing device. The locking assembly 20 is arranged on the mounting structure 10. The locking assembly 20 includes a driving structure 21 and a locking member 22. The driving structure 21 is drivingly connected to the locking member 22 to drive the locking member 22 to move. The locking member 22 has a locking position and a release position. When the locking member 22 is in the locking position, at least part of the outer surface of the locking member 22 abuts against the tool 1 to lock the tool 1 in the housing portion 11; when the locking member 22 is in the release position, the locking member 22 is separated from the tool 1.

[0033] According to the technical solution of this embodiment, the tool changing device is rotatably arranged on the main body of the processing equipment and includes a mounting structure 10. The mounting structure 10 has a housing 11 and a avoidance opening 12 connected to the housing 11. The housing 11 is used to accommodate the tool 1. The avoidance opening 12 is used to allow the tool 1 to move into the housing 11 during the rotation of the tool changing device. The locking assembly 20 is arranged on the mounting structure 10. The driving structure 21 of the locking assembly 20 is drivingly connected to the locking member 22 to drive the locking member 22 to move. The locking member 22 has a locking position and a release position. When the locking member 22 is in the locking position, at least part of the outer surface of the locking member 22 abuts against the tool 1 to lock the tool 1 in the housing 11; when the locking member 22 is in the release position, the locking member 22 is separated from the tool. In this way, after the tool 1 enters the accommodating portion 11, the driving structure 21 will drive the locking member 22 to move to the locking position, and after the locking member 22 abuts against the tool 1, the thrust is continuously output to the locking member 22, thereby ensuring that the tool 1 can be stably locked and fixed in the accommodating portion 11. Compared with the spring locking method in the prior art, the driving structure 21 does not have the problem of aging or jamming, which greatly improves the locking stability of the tool 1, thereby solving the problem of poor locking stability of the tool on the tool changing arm of the machine tool in the prior art. At the same time, for the tool changing process, this embodiment actually adopts an open tool feeding method, that is, only by rotating the tool changing device, the tool to be replaced on the machine tool can enter the accommodating portion 11 through the avoidance opening 12, so as to perform subsequent locking and replacement steps, which greatly reduces the difficulty of tool replacement and positioning requirements.

[0034] like Figures 1 to 6As shown, the mounting structure 10 includes a mounting body 13 and an extension arm 14 disposed on the mounting body 13, and a receiving recess 141 is disposed on the extension arm 14, the opening of the receiving recess 141 forms an avoidance opening 12, and the inner wall of the receiving recess 141 forms a receiving portion 11. Among them, the receiving recess 141 runs through the extension arm 14. In this way, the through-type design of the receiving recess 141 enables the mounting structure 10 to be compatible with tools 1 of different sizes (heights), thereby improving the versatility of the tool changing device. At the same time, the above-mentioned arrangement also makes the formation of the receiving portion 11 and the avoidance opening 12 simpler, thereby reducing the processing cost of the tool changing device and the processing difficulty of the staff.

[0035] In this embodiment, the inner wall of the accommodating recess 141 is an arc-shaped surface to match the outer peripheral surface structure of the tool 1, thereby increasing the contact area between the accommodating portion 11 and the tool 1, and further improving the locking and fixing stability of the tool 1.

[0036] It should be noted that the inner wall structure of the accommodating recess 141 is not limited thereto, and can be adjusted accordingly according to working conditions and usage requirements.

[0037] In this embodiment, the mounting body 13 and the extension arm 14 are both plate-shaped. When the tool changing device rotates, the plate surfaces of the mounting body 13 and the extension arm 14 rotate horizontally, and the accommodating recess 141 penetrates the extension arm 14 along the thickness direction of the extension arm 14.

[0038] Optionally, the locking assembly 20 is arranged on the installation body 13, the locking member 22 is located at the opening side of the accommodating recess 141, and the installation structure 10 further includes a locking fitting 15, which is arranged on the extension arm 14, and at least part of the locking fitting 15 extends into the first recess 101 of the tool 1, and the locking fitting 15 is stopped by the inner wall of the first recess 101 to stop the tool 1 from rotating during the locking process of the locking member 22. In this way, since the outer peripheral surface of the tool 1 is an arc surface, it is easy to rotate in the accommodating portion 11, and the tool 1 is stopped by setting the locking fitting 15 to ensure that the tool 1 will not rotate during the locking process of the locking member 22, and the locking reliability of the locking member 22 is further improved.

[0039] In this embodiment, the longer driving structure 21 is arranged along the length direction of the installation body 13 to reduce the width dimension of the installation body 13, realize the miniaturized design of the tool changing device, and ensure that the tool changing device can move smoothly in a machine tool with limited size.

[0040] In this embodiment, when the locking member 22 moves to the locking position, its end portion extends into the first recess 101 and abuts against the inner wall of the first recess 101, so as to limit the end portion of the locking member 22 through the first recess 101, thereby ensuring a high abutment reliability between the locking member 22 and the tool 1.

[0041] In this embodiment, the locking member 22 is columnar, one end of which is drivingly connected to the driving structure 21, and the other end is provided with two inclined surfaces arranged opposite to each other, and the distance between the two inclined surfaces gradually decreases in the direction from the driving structure 21 to the locking member 22, so as to form an abutting end. In this way, the above arrangement can reduce the size of the abutting end, ensuring that the abutting end can smoothly enter the first recess 101.

[0042] Specifically, the driving direction of the driving structure 21 arranged along the length direction of the mounting body 13 is actually parallel to the tangential direction of the outer peripheral surface of the tool 1. Therefore, after the locking member 22 abuts against the tool 1, it will drive the tool 1 to rotate. In this embodiment, the tool 1 is stopped from rotating by setting a locking fitting 15, so that the locking member 22 and the locking fitting 15 interact with each other, thereby greatly improving the locking and fixing stability of the tool 1.

[0043] In this embodiment, the locking fitting 15 is in a plate shape, and the structure of the portion thereof extending into the first recess 101 matches the structure of the first recess 101 .

[0044] like Figure 1 , Figure 2 and Figures 4 to 6 As shown, a limiting portion 142 is also provided on the inner wall of the accommodating recess 141. The limiting portion 142 is a protrusion and extends into the second recess 102 of the tool 1. The limiting portion 142 is limited by the inner wall of the second recess 102 to limit the tool 1 in the height direction of the tool 1; or, the limiting portion 142 is a recess and is used for the first protrusion of the tool 1 to extend into. The inner wall of the limiting portion 142 is limited by the first protrusion to limit the tool 1 in the height direction of the tool 1. In this way, the above-mentioned setting, on the one hand, further limits the tool 1 in its height direction through the limiting portion 142, further reducing the possibility of the tool 1 escaping from the accommodating portion 11; on the other hand, the structure of the limiting portion 142 is made more flexible and diverse to adapt to different working conditions and use requirements, and also improves the processing flexibility of the staff.

[0045] In this embodiment, the limiting portion 142 is a protrusion to match the second recess 102 on the tool 1 .

[0046] In this embodiment, the limiting portion 142 is a strip-shaped protrusion, which is arranged around the tool 1 to increase the matching area between the limiting portion 142 and the tool 1, thereby improving the limiting reliability of the limiting portion 142.

[0047] like Figure 1 , Figure 4 and Figure 6 As shown, the mounting structure 10 further comprises a mounting cavity and a through hole 16 communicating with the mounting cavity, the driving structure 21 is arranged in the mounting cavity, and at least part of the locking member 22 is slidably arranged in the through hole 16. In this way, by arranging the driving structure 21 in the mounting cavity, the driving structure 21 can be protected to prevent impurities from splashing onto the driving structure 21 during the machining process of the machine tool, thereby preventing the driving structure 21 from being damaged during operation, which not only improves the operating stability of the tool changing device, but also prolongs the service life of the driving structure 21.

[0048] like Figure 4 and Figure 6 As shown, the installation body 13 has an installation recess 131, and the installation structure 10 also includes a guide member 17 and a cover member 18, wherein the guide member 17 is arranged on one side of the installation recess 131. The cover member 18 is covered on the installation recess 131, and an installation cavity is formed around the guide member 17, the cover member 18 and the inner wall of the installation recess 131. Among them, the guide member 17 has a through hole 16, and the through hole 16 is used to guide the movement direction of the locking member 22. In this way, the above-mentioned setting makes the formation of the installation cavity simpler and easier to process and realize on the one hand; on the other hand, by guiding the movement direction of the locking member 22 through the through hole 16, it is further ensured that the locking member 22 can be stably abutted against the tool 1. At the same time, the staff can disassemble the cover member 18 to inspect and replace the driving structure 21 located in the installation recess 131, thereby reducing the difficulty of inspection and maintenance for the staff.

[0049] like Figure 1 , Figure 4 and Figure 6 As shown, the mounting structure 10 is also provided with a connection hole 19, which is used for driving connection with the driving member of the processing equipment body. The driving structure 21 is a driving cylinder. In this way, the above arrangement enables the tool changing device to be drivingly connected with the driving member of the machine tool (processing equipment body) through the connection hole 19, so as to realize the assembly between the tool changing device and the machine tool; on the other hand, the locking member 22 is driven to move by the driving cylinder, which not only ensures that the locking member 22 has a high movement stroke accuracy, but also can provide a stable locking force for the locking member 22, further improving the locking reliability of the locking member 22.

[0050] In this embodiment, the driving cylinder is a pneumatic cylinder.

[0051] Optionally, there are at least two receiving parts 11 and at least two locking assemblies 20, and at least two receiving parts 11 are arranged in one-to-one correspondence with at least two locking assemblies 20, and at least one receiving part 11 is used to accommodate the tool 1 to be replaced, and at least another receiving part 11 is used to accommodate the replaced tool 1. In this way, the above arrangement, on the one hand, enables the tool changing device to complete the removal of the installed tool on the machine tool and the installation of the tool to be installed at one time, thereby improving the tool changing efficiency of the tool changing device; on the other hand, it makes the number of receiving parts 11 more flexible and diverse to adapt to different working conditions and usage requirements.

[0052] In this embodiment, there are two receiving portions 11 and two locking assemblies 20 , and the two locking assemblies 20 are disposed in a one-to-one correspondence with the two receiving portions 11 .

[0053] It should be noted that the number of the accommodating portions 11 is not limited thereto, and can be adjusted according to working conditions and usage requirements to achieve synchronous replacement of multiple tools.

[0054] In this embodiment, the two accommodating parts 11 are respectively located on both sides of the connecting hole 19, and the avoidance openings 12 are oriented in opposite directions. In this way, after the tool changing device rotates clockwise or counterclockwise until the installed tool on the machine tool enters one accommodating part 11 and is locked, it only needs to continue to rotate clockwise or counterclockwise to adjust the tool to be installed in the other accommodating part 11 to the tool installation position of the machine tool without reversing, thereby making the control logic of the tool changing device simpler.

[0055] In this embodiment, the tool changing device also includes a detection device and a control module. The detection device is arranged on the mounting structure 10. When the locking member 22 is located at the locking position, the detection device detects whether the locking member 22 and / or the driving shaft of the driving structure 21 exist at the preset position. The control module is connected to both the detection device and the main body of the processing equipment. The control module controls the main body of the processing equipment to run or stop running according to the detection value of the detection device. In this way, when the detection device does not detect the presence of the locking member 22 and / or the driving shaft of the driving structure 21 at the preset position, it means that the locking member 22 has not moved into place, and the tool 1 is in an incompletely locked state at this time. By controlling the main body of the processing equipment to stop running through the control module, the occurrence of "knife flinging" and "knife falling off" phenomena can be effectively avoided, thereby ensuring the personal safety of the staff.

[0056] In this embodiment, the detection device is a magnetic switch, which is used to detect whether there is a driving shaft of the driving structure 21 at the preset position. That is, if the locking member 22 moves into place, the driving shaft of the driving structure 21 will move to the preset position and trigger the magnetic switch. The control module can then determine through the electrical signal of the magnetic switch that the locking member 22 in the locking position has moved into place. Otherwise, it means that the driving stroke of the driving structure 21 is less than the preset stroke, and the tool 1 is not completely locked.

[0057] In this embodiment, the tool changing device also includes an alarm device, which is used to send an alarm signal, and the alarm signal includes at least one of a sound signal and a light signal. The control module is connected to the alarm device, and the control module controls the alarm device to run or stop running according to the detection value of the detection device. In this way, the above setting can remind the staff to ensure that the staff can inspect and maintain the tool changing device in time, avoid the problem of long-term shutdown of the machine tool, and thus improve the processing efficiency of the machine tool.

[0058] The present application also provides a processing device, which includes a processing device body and a tool changing device arranged on the processing device body, wherein a driving member of the processing device body is connected to the tool changing device through a connecting hole 19 of a mounting structure 10 of the tool changing device, and the driving member is used to drive the tool changing device to rotate and / or lift and lower. The tool changing device is the above-mentioned tool changing device.

[0059] In this embodiment, the processing equipment is a machine tool.

[0060] Specifically, the tool changing process of the machine tool is as follows:

[0061] When the machine tool starts the tool changing mode, the driving member first descends as a whole and drives the tool changing device to descend to the specified position, and then drives the tool changing device to start rotating, until the installed tool on the machine tool moves into the accommodating portion 11 through the avoidance opening, and the driving structure 21 starts to drive the locking member 22 to move to the locking position to lock the installed tool on the machine tool, and then the driving member continues to drive the tool changing device to rotate. While the installed tool on the machine tool is taken away, the tool to be installed on the tool changing device moves to the tool installation position on the machine tool. After the tool to be installed is clamped by the machine tool fixture, the driving structure 21 that locks the tool to be installed drives the locking member 22 to move to the released position, and continues to rotate the preset angle to allow the limit portion 142 to withdraw, and the driving member drives the tool changing device back to its original position, and the tool changing process ends.

[0062] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0063] The tool changing device is rotatably arranged on the main body of the processing equipment and includes a mounting structure, the mounting structure has a housing portion and an escape port connected to the housing portion, the housing portion is used to accommodate the tool, the escape port is used to allow the tool to move into the housing portion during the rotation of the tool changing device, and the locking assembly is arranged on the mounting structure, and the driving structure of the locking assembly is drivingly connected to the locking member to drive the locking member to move. The locking member has a locking position and a release position, when the locking member is in the locking position, at least part of the outer surface of the locking member abuts against the tool to lock the tool in the housing portion; when the locking member is in the release position, the locking member is separated from the tool. In this way, after the tool enters the accommodating portion, the driving structure will drive the locking member to move to the locking position, and after the locking member abuts against the tool, it will continuously output thrust to the locking member, thereby ensuring that the tool can be stably locked and fixed in the accommodating portion. Compared with the spring locking method in the prior art, the driving structure does not have the problem of aging or jamming, which greatly improves the locking stability of the tool, thereby solving the problem of poor locking stability of the tool on the tool changing arm of the machine tool in the prior art. At the same time, for the tool changing process, the present application actually adopts an open tool feeding method, that is, only by rotating the tool changing device, the tool to be replaced on the machine tool can enter the accommodating portion through the avoidance port, so as to perform subsequent locking and replacement steps, which greatly reduces the difficulty of tool replacement and positioning requirements.
