During the meticulous dismantling and recycling of used batteries, the busbars are usually removed using milling equipment. However, traditional milling equipment still suffers from low replacement efficiency when changing the milling cutter, thus affecting the production efficiency of the milling equipment.

[0006] In an optional embodiment, the first clamping member includes a first connecting portion and a first clamping portion connected to the first connecting portion, and the second clamping member includes a second connecting portion and a second clamping portion connected to the second connecting portion. The first connecting portion and the second connecting portion are respectively connected to both ends of the elastic member and are rotatably connected to the base. The first clamping portion and the second clamping portion are respectively located on both sides of the first limiting member, and the cutting edge is located between the end of the first clamping portion away from the elastic member and the end of the second clamping portion away from the elastic member.

[0007] In an optional embodiment, the tool changing device further includes a base and a sliding assembly, the sliding assembly being disposed on the base and sliding relative to the base, and the multi-station tool magazine being connected to the sliding assembly.

[0008] In an optional embodiment, the sliding assembly includes a sliding platform and a first driving member, the base is connected to the sliding platform, and the first driving member is connected to the sliding platform and is used to drive the sliding platform to slide relative to the base.

[0009] In an optional embodiment, the sliding assembly further includes a guide and a slide rail, the slide rail being connected to the base, the guide being slidably connected to the slide rail, and the sliding platform being fixedly connected to the guide.

[0010] In an optional embodiment, the tool changing device further includes a buffer assembly connected to the base and spaced apart from the sliding platform along the sliding direction of the sliding platform, and the buffer assembly is at least partially located on the same plane as the sliding platform.

[0011] In an optional embodiment, the buffer assembly includes an elastic buffer, a second limiting member, and a connecting member.

[0012] In an optional embodiment, the tool changing device further includes a protective component disposed on the sliding platform. The protective component includes a protective cover that rotates relative to the sliding platform to either conceal the multi-station tool magazine within the protective cover or expose the multi-station tool magazine outside the protective cover.

[0013] In an optional embodiment, the protective assembly further includes a second drive member and a transmission shaft.

[0014] Secondly, this application provides a milling machine, including a tool changing device as described in any of the foregoing embodiments.

[0015] The tool changing device of this application has the following advantages:

[0016] In the tool changing device of this application, the tool changing device can buffer multiple tools simultaneously to improve tool changing efficiency. During the tool changing process, the first clamping member and the second clamping member can be limited by a limiting member to ensure that an inlet / outlet is reserved between the first clamping member and the second clamping member. This allows the tool to enter between the first clamping member and the second clamping member through the inlet / outlet, eliminating the need for manual movement of the first clamping member and the second clamping member, thus improving tool changing efficiency. When the tool passes through the inlet / outlet, it exerts a compressive force on the first clamping member and the second clamping member, causing them to rotate relative to the base in a direction away from each other. This allows the tool to be pushed into the space between the first clamping member and the second clamping member through the inlet / outlet, thereby clamping the tool. When the tool enters the space between the first clamping member and the second clamping member... The elastic force of the elastic element causes the first and second clamping elements to tend to move closer to each other, thereby improving the clamping effect of the first and second clamping elements on the tool. This tool changing process does not require manual manipulation of the first and second clamping elements to clamp the tool, thus further improving the tool changing efficiency. Furthermore, the position sensor can detect whether the first and second clamping elements are in a preset position. When the first and second clamping elements are in the preset position, the elastic element is in a natural state. At this time, no tool is clamped between the first and second clamping elements. When any position sensor detects that the first and second clamping elements of the clamping assembly are in the preset position, it means that the tool can enter the clamping assembly and be clamped, thereby preventing the tool from being pushed to the clamping assembly that already holds the tool, thus further improving the tool changing efficiency.

[0040] Reference Figure 1 , Figure 3 as well as Figure 4 As shown, the tool changing device 10 involved in the embodiments of this application includes: a multi-station tool magazine 100.

[0041] Specifically, the multi-station tool magazine 100 includes a base 110, multiple clamping assemblies 120, and multiple position sensors 130. The multiple clamping assemblies 120 are spaced apart on the base 110. Each clamping assembly 120 includes a first clamping member 121, a second clamping member 122, an elastic member 123, and a first limiting member 124. The two ends of the elastic member 123 are respectively connected to the first clamping member 121 and the second clamping member 122, and both the first clamping member 121 and the second clamping member 122 are rotatably connected to the base 110. The elastic member 123 has the function of driving the first clamping member 121... The elastic potential energy that is close to the second clamping member 122; the first limiting member 124 is disposed on the base 110 and between the first clamping member 121 and the second clamping member 122, so that the cutting edge 125 is spaced between the first clamping member 121 and the second clamping member 122; each position sensor 130 is located at the location of a clamping component 120 and is used to monitor the position signals of the first clamping member 121 and the second clamping member 122 at a preset position. When the first clamping member 121 and the second clamping member 122 are at the preset position, the elastic member 123 is in a natural state.

[0042] In the tool changing device 10 of this application, the tool changing device 10 can simultaneously buffer multiple tools 20 to improve tool changing efficiency. During the tool changing process, the first limiting member 124 can limit the first clamping member 121 and the second clamping member 122 to ensure that an inlet 125 is reserved between the first clamping member 121 and the second clamping member 122, so that the tool 20 can enter between the first clamping member 121 and the second clamping member 122 through the inlet 125. Therefore, the tool 20 can enter without manually moving the first clamping member 121 and the second clamping member 122. The tool 20 is inserted between the first clamping member 121 and the second clamping member 122 to improve tool changing efficiency. When the tool 20 passes through the tool inlet 125, the tool 20 exerts a squeezing force on the first clamping member 121 and the second clamping member 122, causing the first clamping member 121 and the second clamping member 122 to move away from each other relative to the base 110. This allows the tool 20 to be pushed into the space between the first clamping member 121 and the second clamping member 122 through the tool inlet 125, thereby clamping the tool 20. When the tool 20 enters the space between the first clamping member 121 and the second clamping member 122, it is inserted into the space between the first clamping member 121 and the second clamping member 122 to improve tool changing efficiency. When the two clamping members 122 are in place, the elastic force of the elastic member 123 will cause the first clamping member 121 and the second clamping member 122 to tend to move closer to each other, thereby improving the clamping effect of the first clamping member 121 and the second clamping member 122 on the tool 20. This tool changing process does not require manual manipulation of the first clamping member 121 and the second clamping member 122 to clamp the tool 20, thus further improving the tool changing efficiency. Furthermore, the position sensor 130 can sense whether the first clamping member 121 and the second clamping member 122 are in a preset position. When the first clamping member 121 and the second clamping member 122 are in the preset position, the elastic member 123 is in the natural state. At this time, there is no tool 20 between the first clamping member 121 and the second clamping member 122. When any position sensor 130 senses that the first clamping member 121 and the second clamping member 122 of the clamping assembly 120 are in the preset position, it means that the tool 20 can enter the clamping assembly 120 and be clamped, thereby preventing the tool 20 from being pushed to the clamping assembly 120 that already holds the tool 20, thereby further improving the tool changing efficiency.

[0043] Reference Figure 4As shown, the first clamping member 121 includes a first connecting portion 1211 and a first clamping portion 1212 connected to the first connecting portion 1211. The second clamping member 122 includes a second connecting portion 1221 and a second clamping portion 1222 connected to the second connecting portion 1221. The first connecting portion 1211 and the second connecting portion 1221 are respectively connected to both ends of the elastic member 123 and are rotatably connected to the base 110. The first clamping portion 1212 and the second clamping portion 1222 are respectively located on both sides of the first limiting member 124. The cutting edge 125 is located between the end of the first clamping portion 1212 away from the elastic member 123 and the end of the second clamping portion 1222 away from the elastic member 123.

[0044] In this embodiment, the tool changing device 10 has a first direction x.

[0045] It should be noted that the first direction x is Figure 1 The direction indicated by x in the middle.

[0046] Specifically, in this embodiment, the elastic element 123 is a spring, which extends along the first direction x. The first clamping element 121 and the second clamping element 122 are symmetrically arranged at both ends of the spring along the first direction x. The first connecting part 1211 and the second connecting part 1221 are respectively connected to the two ends of the spring along the first direction x. The first clamping part 1212 and the second clamping part 1222 are respectively located on both sides of the first limiting element 124 along the first direction x, so that the tool 20 can enter between the first clamping part 1212 and the second clamping part 1222 through the inlet 125, and the first clamping part 1212 and the second clamping part 1222 respectively clamp the tool 20 on both sides along the first direction x, so as to achieve clamping of the tool 20.

[0047] In this embodiment, the cutting tool 20 can be pushed into the space between the first clamping part 1212 and the second clamping part 1222 through the inlet 125. When the cutting tool 20 enters the space between the first clamping part 1212 and the second clamping part 1222, the cutting tool 20 will exert a squeezing force on the first clamping part 1212 and the second clamping part 1222, thereby causing the first clamping part 1212 to drive the first connecting part 1211 to rotate relative to the base 110, and at the same time causing the second clamping part 1222 to drive the second connecting part 1221 to rotate relative to the base 110. The first connecting portion 1211 and the second connecting portion 1221 move in opposite directions, causing them to exert a compressive force on the elastic member 123. This gives the elastic member 123 the elastic potential energy to drive the first connecting portion 1211 and the second connecting portion 1221 closer together. Furthermore, this allows the first connecting portion 1211 and the second connecting portion 1221 to move towards each other after moving in opposite directions, thereby causing the first clamping portion 1212 and the second clamping portion 1222 to move towards each other after moving in opposite directions. The movement clamps the tool 20 between the first clamping part 1212 and the second clamping part 1222, thereby achieving automatic clamping of the tool 20 and improving tool changing efficiency. Furthermore, the principle for removing the tool 20 from between the first clamping part 1212 and the second clamping part 1222 is the same as the principle for placing the tool 20 between them. Through the cooperation between the elastic element 123 and the first clamping part 1212 and the second clamping part 1222, the tool 20 is automatically removed. After the first clamping part 1212 and the second clamping part 1222 are removed from between the first clamping part 1212 and the second clamping part 1222, they will move towards each other under the action of the elastic potential energy of the elastic member 123. At this time, the first limiting member 124 can limit the movement of the first clamping part 1212 and the second clamping part 1222, so as to ensure that the inlet 125 can always be reserved between the first clamping part 1212 and the second clamping part 1222, so that the next tool 20 can enter between the first clamping member 121 and the second clamping member 122 through the inlet 125.

[0048] Reference Figure 4 as well as Figure 8As shown, the first clamping member 121 further has a first limiting portion 1213, which is connected to the first clamping portion 1212 and protrudes from the first clamping portion 1212 along the first direction x toward the direction close to the second clamping member 122. The second clamping member 122 further has a second limiting portion 1223, which is connected to the second clamping portion 1222 and protrudes from the second clamping portion 1222 along the first direction x toward the direction close to the first clamping member 121. The first limiting portion 1213 and the second limiting portion 1223 are relative to the first limiting portion 1212. The positioning members 124 are symmetrically arranged. The tool 20 has a limiting groove 21. The limiting groove 21 is at least partially recessed in the first direction x toward the inside of the tool 20. The first limiting part 1213 and the second limiting part 1223 are both inserted through the limiting groove 21 and abut against the groove wall of the limiting groove 21. The cooperation between the first limiting part 1213 and the second limiting part 1223 and the limiting groove 21 enhances the clamping effect of the first clamping member 121 and the second clamping member 122 on the tool 20 and prevents the tool 20 from falling out between the first clamping member 121 and the second clamping member 122.

[0049] Reference Figure 2 As shown, the tool changing device 10 also includes a base 200 and a sliding component 300. The sliding component 300 is disposed on the base 200 and slides relative to the base 200. The multi-station tool magazine 100 is connected to the sliding component 300.

[0050] In this embodiment, the tool changing device 10 also has a second direction y, which intersects with the first direction x.

[0051] It should be noted that the second direction y is Figure 1 The direction indicated by y in the middle.

[0052] Specifically, in this embodiment, the sliding component 300 slides relative to the base 200 along the second direction y.

[0053] In this embodiment, the multi-station tool magazine 100 can be slid relative to the base 200 by the sliding component 300, so as to slide the multi-station tool magazine 100 to the position of the milling spindle (i.e. the tool changing position) to facilitate tool changing, thereby further improving the tool changing efficiency.

[0054] Reference Figure 5 As shown, the sliding assembly 300 includes a sliding platform 310 and a first driving member 320. The base 110 is connected to the sliding platform 310, and the first driving member 320 is connected to the sliding platform 310 and is used to drive the sliding platform 310 to slide relative to the base 200.

[0055] Specifically, in this embodiment, the first driving member 320 drives the sliding platform 310 to slide relative to the base 200 along the second direction y.

[0056] In this embodiment, the sliding platform 310 can be driven to slide relative to the base 200 by the first driving member 320, so that the base 110 can slide relative to the base 200 by the sliding platform 310, thereby driving the multiple clamping components 120 connected to the base 110 to slide relative to the base 110, so as to push the tool 20 to the tool changing position.

[0057] Continue to refer to Figure 5 As shown, the sliding assembly 300 also includes a guide 330 and a slide rail 340. The slide rail 340 is connected to the base 200, the guide 330 is slidably connected to the slide rail 340, and the sliding platform 310 is fixedly connected to the guide 330.

[0058] Specifically, in this embodiment, the slide rail 340 extends along the second direction y, and the sliding platform 310 is provided with slide rails 340 at both ends along the first direction x, so as to improve the smoothness of the sliding platform 310 sliding along the second direction y.

[0059] In this embodiment, since the slide rail 340 is connected to the base 200 and the guide member 330 is slidably connected to the slide rail 340, when the guide member 330 slides relative to the slide rail 340, it can slide relative to the base 200. Since the sliding platform 310 is fixedly connected to the guide member 330, the guide member 330 can drive the sliding platform 310 to slide relative to the slide rail 340, thereby realizing the sliding of the sliding platform 310 relative to the base 200. In this process, the cooperation between the guide member 330 and the slide rail 340 can guide the sliding of the sliding platform 310 and improve the directional accuracy of the sliding of the sliding platform 310.

[0060] Reference Figure 2 as well as Figure 5 As shown, the tool changing device 10 also includes a buffer assembly 400, which is connected to the base 200 and is spaced apart from the sliding platform 310 along the sliding direction of the sliding platform 310. The buffer assembly 400 is at least partially located on the same plane as the sliding platform 310.

[0061] In this embodiment, the tool changing device 10 also has a third direction z, and the first direction x, the second direction y and the third direction z intersect each other in pairs.

[0062] It should be noted that the third party is z. Figure 1 The direction indicated by z in the middle.

[0063] Specifically, in this embodiment, the sliding platform 310 extends along a direction perpendicular to the third direction z, and the buffer component 400 is at least partially located on the same platform surface perpendicular to the third direction z as the sliding platform 310. Thus, when the sliding platform 310 slides relative to the base 200, at least a portion of the buffer component 400 can abut against the sliding platform 310.

[0064] In this embodiment, since the buffer assembly 400 and the sliding platform 310 are spaced apart along the sliding direction of the sliding platform 310, and at least part of the buffer assembly 400 is located on the same plane as the sliding platform 310, when the sliding platform 310 slides relative to the base 200, at least part of the buffer assembly 400 can abut against the sliding platform 310, so that the buffer assembly 400 can limit and buffer the sliding of the sliding platform 310, thereby determining the sliding end point position of the sliding platform 310 and improving the accuracy of the clamping assembly 120 sliding to the tool changing position.

[0065] Specifically, refer to Figure 5 As shown, in this embodiment, buffer components 400 are provided at both ends of the sliding platform 310 along the second direction y, and the buffer components 400 at both ends of the sliding platform 310 along the second direction y are spaced apart from the sliding platform 310, so that the sliding platform 310 can move along the second direction y between the buffer components 400 at both ends, thereby realizing the switching of the multi-station tool magazine 100 between the tool changing position and the tool storage position. At the same time, the buffer components 400 at both ends can limit and buffer the sliding of the sliding platform 310, thereby improving the accuracy of the clamping component 120 sliding to the tool changing position or the tool storage position.

[0066] Reference Figure 6 As shown, the buffer assembly 400 includes an elastic buffer 410, a second limiting member 420, and a connecting member 430. The connecting member 430 is connected to the base 200. Both the elastic buffer 410 and the second limiting member 420 are connected to the connecting member 430. Both the elastic buffer 410 and the second limiting member 420 are at least partially located on the same plane as the sliding platform 310. In the sliding direction along the sliding platform 310, the end of the elastic buffer 410 near the sliding platform 310 is parallel to or protrudes from the end of the second limiting member 420 near the sliding platform 310.

[0067] Specifically, in this embodiment, the connector 430 protrudes from the base 200 along the third direction z, and the height of the connector 430 along the third direction z is greater than the distance between the sliding platform 310 and the base 200 in the third direction z. The elastic buffer 410 and the second limiting member 420 are at least partially located on the same plane perpendicular to the third direction z with the sliding platform 310, so that the elastic buffer 410 and the second limiting member 420 connected to the connector 430 can abut against the sliding platform 310.

[0068] In this embodiment, since both the elastic buffer 410 and the second limiting member 420 are at least partially located on the same plane as the sliding platform 310, when the sliding platform 310 slides relative to the base 200, the elastic buffer 410 and / or the second limiting member 420 can abut against the sliding platform 310 to limit the sliding of the sliding platform 310, thereby improving the accuracy of the clamping assembly 120 sliding to the tool changing position. Along the sliding direction of the sliding platform 310, since the end of the elastic buffer 410 near the sliding platform 310 is parallel to or protrudes from the end of the second limiting member 420 near the sliding platform 310... One end of the sliding platform 310 is positioned such that when the sliding platform 310 slides, it first abuts against the elastic buffer 410 and then against the second limiting member 420. The elastic buffer 410 absorbs the impact potential energy during the sliding process of the sliding platform 310, thereby reducing the impact force of the sliding platform 310 on the second limiting member 420. This prevents the sliding platform 310 from being bounced off the second limiting member 420 after colliding with it, thereby improving the consistency of the sliding platform 310 sliding to the end position and improving the accuracy of the clamping assembly 120 sliding to the tool changing position.

[0069] Reference Figure 2 as well as Figure 7 As shown, the tool changing device 10 also includes a protection component 500, which is disposed on the sliding platform 310. The protection component 500 includes a protective cover 510, which rotates relative to the sliding platform 310 to either hide the multi-station tool magazine 100 inside the protective cover 510 or expose the multi-station tool magazine 100 outside the protective cover 510.

[0070] Specifically, in this embodiment, the base 110 extends along the first direction x, a plurality of clamping components 120 are spaced apart on the base 110 along the first direction x, and the protective cover 510 extends along the first direction x and rotates relative to the sliding platform 310 about the first direction x, so that the multi-station tool magazine 100 is hidden inside the protective cover 510 or exposed outside the protective cover 510.

[0071] In this embodiment, when a tool change is required, the protective cover 510 can rotate relative to the sliding platform 310 so that the multi-station tool magazine 100 is exposed outside the protective cover 510, thereby facilitating tool change on the clamping assembly 120. During milling operations, the protective cover 510 can rotate in the opposite direction relative to the sliding platform 310 so that the multi-station tool magazine 100 is hidden inside the protective cover 510. Thus, the protective cover 510 protects the tools 20 on the multi-station tool magazine 100, preventing high-speed metal chips generated during milling operations from falling onto the tools 20, avoiding damage to the tools 20, and improving the reliability of the milling equipment.

[0072] Reference Figure 7 As shown, the protection component 500 also includes a second drive member 520 and a transmission shaft 530. The second drive member 520 is disposed on the sliding platform 310 and connected to the transmission shaft 530. The second drive member 520 is used to drive the transmission shaft 530 to rotate. The protective cover 510 is connected to the transmission shaft 530.

[0073] Specifically, in this embodiment, the drive shaft 530 extends along the first direction x, and the protective cover 510 is connected to the drive shaft 530 at various points along the first direction x. The second drive member 520 is used to drive the drive shaft 530 to rotate around the first direction x, so as to realize the rotation of the protective cover 510 around the first direction x.

[0074] In this embodiment, the transmission shaft 530 can be driven to rotate by the second driving member 520, so that the protective cover 510 can be rotated by the transmission shaft 530, thereby realizing the rotation of the protective cover 510 relative to the sliding platform 310, so that the multi-station tool magazine 100 is hidden inside the protective cover 510 or exposed outside the protective cover 510, thereby facilitating tool changing or protecting the tool 20.
