[0069] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0070] Please refer to Figure 1 、 Figure 2 and Figure 3 The embodiment of the present application provides an interchangeable positioning device 100, which includes an interchangeable working platform 10, a bearing assembly 20, a fixing assembly 30, an operating mechanism 40, and a clamping assembly 50. For ease of understanding and explanation, Figure 1 The X-axis direction shown in the figure is the first direction, the Y-axis direction is the second direction, and the first direction is perpendicular to the second direction.

[0071] An inserting member 11 is protruding from one side of the interchangeable work platform 10, and the other side opposite to the interchangeable work platform 10 is used to carry and position the workpiece. The bearing assembly 20 is used to carry the interchangeable work platform 10, and the bearing assembly 20 is provided with a through hole 211 adapted to the inserting member 11, and the through hole 211 is used for the inserting member 11 to pass through. The fixing assembly 30 includes a support member 31 and a supporting member 32 spaced apart along a first direction, and a guide member 33 connecting the support member 31 and the supporting member 32. The support member 31 is provided on the side of the bearing assembly 20 away from the interchangeable work platform 10, and the supporting member 32 is located on the side of the support member 31 away from the bearing assembly 20. The support member 31 is provided with a through opening 311 extending along the first direction. Specifically, one end of the guide member 33 is connected to the support member 31, and the other end of the guide member 33 is connected to the supporting member 32. In this embodiment, the support member 31 and the supporting member 32 are both plate-like structures. In other embodiments, the support member 31 and the supporting member 32 may also be of other shapes.

[0072] The operating mechanism 40 includes an operating component 41, a floating component 42 and a driving elastic component 43. The floating component 42 is slidably mounted on the guide component 33 along the first direction and abuts against the operating component 41. The side of the floating component 42 abutting against the operating component 41 has a pressure inclined surface 4211. The operating component 41 is arranged on the support component 31 and slides on the pressure inclined surface 4211. The operating component 41 has an extrusion inclined surface 4121 abutting against the pressure inclined surface 4211. The driving elastic component 43 is mounted on the guide component 33. One end of the driving elastic component 43 abuts against the floating component 42, and the other end of the driving elastic component 43 abuts against the supporting component 32. Specifically, the guide component 33 guides the sliding of the floating component 42 along the first direction.

[0073] The clamping assembly 50 includes a first clamping member 51, a second clamping member 52 and a clamping elastic member 53. One end of the first clamping member 51 and one end of the second clamping member 52 intersect and are rotatably connected to the floating member 42. The other end of the first clamping member 51 is the first clamping end 511, and the other end of the second clamping member 52 is the second clamping end 521. The first clamping end 511 and the second clamping end 521 are arranged opposite to each other and both pass through the through opening 311 and are opposite to the inserted member 11. The clamping elastic member 53 is arranged between the first clamping member 51 and the second clamping member 52. The two ends of the clamping elastic member 53 are respectively connected to the first clamping member 51 and the second clamping member 52.

[0074] The operating assembly 41 can move in the second direction so that the extrusion slope 4121 squeezes the pressure slope 4211 of the floating member 42, thereby driving the floating member 42, the first clamping member 51, and the second clamping member 52 to approach the supporting member 32 in the first direction, so that the first clamping end 511 and the second clamping end 521 are squeezed by the inner side wall of the through-opening 311 and approach each other to clamp the inserted member 11. The driving elastic member 43 is used to drive the floating member 42, the first clamping member 51, and the second clamping member 52 away from the supporting member 32, so that the first clamping end 511 and the second clamping end 521 are moved away from each other under the action of the clamping elastic member 53 and release the inserted member 11. The clamping elastic member 53 can be, but is not limited to, a spring; and the driving elastic member 43 can be, but is not limited to, a spring.

[0075] When the above-mentioned interchangeable positioning device 100 is in use, the fixing component 30 is installed in advance on the machine table of the processing device. When the workpiece needs to be processed, the interchangeable working platform 10 that carries and positions the workpiece is set on the supporting component 20, and the plug-in component 11 of the interchangeable working platform 10 is passed through the through hole 211 of the supporting component 20. Then the operating component 41 moves along the second direction so that the extrusion inclined surface 4121 squeezes the pressure inclined surface 4211 of the floating component 42, thereby driving the floating component 42 along the guide component 33 to approach the supporting component 32, so that the floating component 42 drives the first clamping component 51 and the second clamping component 52 along the first direction relative to the through opening 311 away from the supporting component 21, and then the first clamping end 511 and the second clamping end 521 are close to each other and clamp the plug-in component 11 under the extrusion action of the inner wall of the through opening 311, thereby realizing the positioning of the interchangeable working platform 10. After the interchangeable work platform 10 is positioned, the workpiece is processed by the processing device. While processing the workpiece, another unprocessed workpiece can be installed on another interchangeable work platform 10. After the processing device completes processing the current workpiece, the operating component 41 moves in the opposite direction to make the extrusion slope 4121 cancel the extrusion of the pressure slope 4211, and then drives the elastic member 43 to reset and rebound to drive the floating member 42, the first clamping member 51 and the second clamping member 52 away from the supporting member 32, so that the first clamping end 511 and the second clamping end 521 are separated from each other under the action of the clamping elastic member 53 and release the inserted member 11, thereby canceling the positioning of the interchangeable work platform 10, and then remove the interchangeable work platform 10 carrying the processed workpiece, and set another interchangeable work platform 10 that carries and positions the unprocessed workpiece on the supporting component 20. Repeat the above actions to complete the processing of multiple workpieces. The embodiment of the present application can quickly and reliably clamp the plug-in component 11 of the interchangeable work platform 10 by the first clamping end 511 and the second clamping end 521 by controlling the operating component 41, and can quickly release the plug-in component 11 of the interchangeable work platform 10 by driving the elastic component 43 to reset. Therefore, the embodiment of the present application realizes the rapid fixing and rapid unlocking of the interchangeable work platform 10, and further realizes the rapid replacement of the interchangeable work platform 10, thereby improving the replacement efficiency of the interchangeable work platform 10.

[0076] In this embodiment, there are multiple interchangeable work platforms 10 , which makes it easy to replace different interchangeable work platforms 10 .

[0077] In this embodiment, the workpiece is positioned on the interchangeable work platform 10 by gluing. When replacing a workpiece, the processed workpiece needs to be removed from the interchangeable work platform 10, and then the interchangeable work platform 10 needs to be cleaned to remove the glue traces on the interchangeable work platform 10. Finally, the unprocessed workpiece is glued to the interchangeable work platform 10. In this embodiment of the application, the workpiece can be replaced by directly replacing the interchangeable work platform 10, thereby improving the speed of replacing the workpiece. Moreover, the disassembly and assembly of the workpiece relative to the interchangeable work platform 10 and the cleaning of the interchangeable work platform 10 will not affect the processing of other workpieces, thereby facilitating the improvement of the processing efficiency of the workpiece.

[0078] See Figure 2 , the number of plug-in parts 11 is multiple, and the multiple plug-in parts 11 are arranged at intervals on one side of the interchangeable work platform 10. The number of through holes 211 and the number of clamping assemblies 50 are also multiple. The multiple through holes 211 correspond one-to-one to the multiple plug-in parts 11, and the multiple clamping assemblies 50 correspond one-to-one to the multiple plug-in parts 11. Specifically, by clamping the corresponding plug-in parts 11 by the multiple clamping assemblies 50, it is convenient to improve the reliability of positioning the interchangeable work platform 10. In this embodiment, the number of plug-in parts 11 is four, and the four plug-in parts 11 are respectively arranged at the four corners of the interchangeable work platform 10. The four clamping assemblies 50 respectively clamp the four plug-in parts 11 to reliably position the interchangeable work platform 10. It can be understood that in other embodiments, the number of plug-in parts 11 can also be less than three or more than five.

[0079] In this embodiment, the insert 11 is cylindrical, the through hole 211 is a circular hole, and the diameter of the insert 11 matches the diameter of the through hole 211, so that the insert 11 cannot move radially along the through hole 211. In addition, the clamping assembly 50 clamps the insert 11 to limit the axial movement of the insert 11 along the through hole 211. The through hole 211 and the clamping assembly 50 cooperate to achieve the positioning of the interchangeable work platform 10. In other embodiments, the insert 11 can be of other desired shapes, and the shape of the through hole 211 matches the shape of the insert 11, as long as the radial movement of the insert 11 in the through hole 211 can be limited.

[0080] In this embodiment, an annular groove 111 is defined on the periphery of one end of the inserting member 11 passing through the through hole 211 . The first clamping end 511 of the first clamping member 51 and the second clamping end 521 of the second clamping member 52 are used to clamp opposite sides of the annular groove 111 .

[0081] In this embodiment, the interchangeable work platform 10 has handles 12. These handles 12 facilitate movement of the interchangeable work platform 10. In this embodiment, there are two handles 12, located on opposite sides of the interchangeable work platform 10. These handles 12 facilitate the operator's two-handed grip, allowing for smoother movement of the interchangeable work platform 10. In other embodiments, there may be three or more handles 12, and the locations of the handles 12 may be arranged as needed.

[0082] In this embodiment, the carrier assembly 20 includes a carrier 21 and a connector 22. The carrier 21 is used to support the interchangeable work platform 10. A through hole 211 is defined in the carrier 21. One end of the connector 22 is connected to the carrier 21, and the other end of the connector 22 is connected to the support 31. Specifically, the carrier 21 is connected to the fixing assembly 30 via the connector 22. A gap exists between the carrier 21 and the support 31. The insert 11 extends through the through hole 211 into the gap between the carrier 21 and the support 31, allowing the first clamp 51 and the second clamp 52 to clamp the insert 11.

[0083] In this embodiment, the side of the carrier 21 facing away from the fixing assembly 30 is provided with a plurality of supporting protrusions 212. These supporting protrusions 212 are used to support the interchangeable work platform 10. Specifically, the surface of the interchangeable work platform 10 may be clinging to a small amount of debris. During the positioning process, the interchangeable work platform 10 may rub against the surface of the interchangeable work platform 10, causing wear or scratches. The provision of the supporting protrusions 212 supports the interchangeable work platform 10, leaving the unsupported area of the interchangeable work platform 10 suspended. This reduces the contact area of the interchangeable work platform 10 and the likelihood of friction between the interchangeable work platform 10 and the debris, thereby enhancing the aesthetics of the interchangeable work platform 10. Furthermore, the supporting protrusions 212 provide a more stable support for the interchangeable work platform 10, reducing the likelihood that the side of the interchangeable work platform 10 facing the carrier 21 will be uneven and unable to be stably supported by the carrier 21. In this embodiment, the carrier 21 is a plate-shaped structure. In other embodiments, the carrier 21 may also have other shapes.

[0084] In this embodiment, the connecting member 22 includes a connecting bolt 221 and a foot 222 that is sleeved onto the connecting bolt 221. One end of the connecting bolt 221 is connected to the load-bearing member 21, and the other end of the connecting bolt 221 is connected to the support member 31. One end of the foot 222 abuts the load-bearing member 21, and the other end of the foot 222 abuts the support member 31. The connecting bolt 221 passes through the load-bearing member 21 and is threadedly connected to the support member 31. The foot 222 is provided to define the distance between the load-bearing member 21 and the fixing assembly 30, such that the distance between the load-bearing member 21 and the fixing assembly 30 is equal to the height of the foot 222. It will be understood that in other embodiments, the connecting member 22 may include only the connecting bolt 221.

[0085] In this embodiment, there are multiple connecting members 22, and the multiple connecting members 22 are connected between the carrier 21 and the fixing assembly 30 at intervals. Specifically, the feet 222 of the multiple connecting members 22 are identical, so that the distance between the carrier 21 and the fixing assembly 30 in all areas is equal to the height of the feet 222, which facilitates accurate definition of the distance between the carrier 21 and the fixing assembly 30.

[0086] In this embodiment, there are multiple guide members 33, and the multiple guide members 33 are connected between the support member 31 and the supporting member 32 at intervals. The arrangement of the multiple guide members 33 facilitates the reliable and stable connection between the support member 31 and the supporting member 32.

[0087] In this embodiment, the guide member 33 includes a guide bolt 331 and a guide tube 332 that is sleeved around the guide bolt 331. The guide bolt 331 connects the support member 31 and the bracket 32. One end of the guide tube 332 abuts the support member 31, while the other end of the guide tube 332 abuts the bracket 32. Specifically, the guide bolt 331 passes through the support member 31 and is threadedly connected to the bracket 32. It is understood that in other embodiments, the guide member 33 may include only the guide bolt 331.

[0088] In this embodiment, the floating member 42 is slidably mounted on the guide tube 332 along the first direction. The guide tube 332 guides the movement of the floating member 42 to ensure the accuracy of the movement of the floating member 42 along the first direction. The driving elastic member 43 is mounted on the guide tube 332.

[0089] In this embodiment, the number of driving elastic members 43 is the same as the number of guide members 33 and corresponds one to one. Each driving elastic member 43 is mounted on the guide tube 332 of the corresponding guide member 33. The multiple driving elastic members 43 can reliably elastically support the floating member 42 to drive the floating member 42 away from the supporting member 32 along the first direction.

[0090] Please refer to the following for further information Figure 5 and Figure 6In this embodiment, the operating component 41 includes an operating member 411 and a sliding member 412. The sliding member 412 is slidably arranged on the pressure inclined surface 4211. The extrusion inclined surface 4121 is located on the side of the sliding member 412 that is against the pressure inclined surface 4211. The operating member 411 is arranged on the support member 31 and is connected to the sliding member 412. The operating member 411 is used to drive the sliding member 412 to move along the second direction so that the sliding member 412 squeezes the pressure inclined surface 4211 through the extrusion inclined surface 4121, thereby driving the floating member 42, the first clamping member 51 and the second clamping member 52 to approach the supporting member 32 along the first direction, and then the first clamping end 511 and the second clamping end 521 are squeezed by the inner wall of the through-opening 311 to approach each other and clamp the inserted member 11. Specifically, when the operating member 411 drives the sliding member 412 to move in the opposite direction, the extrusion inclined surface 4121 of the sliding member 412 no longer extrudes the pressure inclined surface 4211, so that the floating member 42, the first clamping member 51 and the second clamping member 52 are driven by the driving elastic member 43 to move away from the supporting member 32 along the first direction, and then the first clamping end 511 and the second clamping end 521 are moved away from each other under the action of the clamping elastic member 53 and release the inserted member 11.

[0091] In this embodiment, the sliding member 412 defines a connection hole 4122 extending in the second direction and communicating with the pressure-bearing inclined surface 4211. The operating member 411 is rotatably mounted on the support member 31 and extends through the connection hole 4122. An external thread 4112a is defined at one end of the operating member 411 extending through the connection hole 4122. An internal thread 4122a mates with the external thread 4112a on the inner wall of the connection hole 4122. Specifically, rotation of the operating member 411 drives the sliding member 412 in the second direction, causing the pressing inclined surface 4121 to press against the pressure-bearing inclined surface 4211, thereby driving the floating member 42, the first clamping member 51, and the second clamping member 52 toward the supporting member 32 in the first direction. Through the arrangement of the internal thread 4122a, the external thread 4112a, the extrusion slope 4121 and the pressure slope 4211, the rotation of the operating member 411 can drive the sliding member 412 to move along the second direction, and the sliding member 412 moving along the second direction can squeeze the floating member 42 so that the floating member 42 approaches the supporting member 32 along the first direction. The floating member 42 can also be driven by the elastic member 43 to move away from the supporting member 32 along the first direction when the sliding member 412 moves along the second direction in the opposite direction to the previous direction.

[0092] Please refer to the following for further information Figure 4In this embodiment, a slide groove 312 extending in the second direction is defined on the side of the support member 31 facing the floating member 42. The sliding member 412 is slidably disposed within the slide groove 312. An opening 3131 extending in the second direction and communicating with the slide groove 312 is defined on the support member 31. The operating member 411 is rotatably disposed within the opening 3131. Specifically, an extension 313 is protruding from the side of the support member 31 facing the floating member 42, and the opening 3131 is formed within the extension 313. The provision of the slide groove 312 facilitates guiding the movement of the sliding member 412 in the second direction, preventing the sliding member 412 from deviating from the moving direction.

[0093] In this embodiment, the operating member 411 includes an operating portion 4111 and a rod 4112 connected to each other, and a limiting protrusion 4113 fixed to the rod 4112, the external thread 4112a is opened on the rod 4112, the rod 4112 passes through the opening 3131 of the extension portion 313, the operating portion 4111 is located on one side of the extension portion 313 in the second direction, and the limiting protrusion 4113 is located on the other side of the extension portion 313 in the second direction. Specifically, the cross-sectional area of the operating portion 4111 and the cross-sectional area of the limiting protrusion 4113 are larger than the cross-sectional area of the opening 3131, the distance between the operating portion 4111 and the limiting protrusion 4113 in the second direction is adapted to the corresponding size of the extension portion 313 in the second direction, and through the arrangement of the operating portion 4111, the limiting protrusion 4113 and the extension portion 313, it is easy to achieve the limitation of the rod 4112 in the second direction, so that the rod 4112 can rotate relative to the extension portion 313, but does not move relative to the extension portion 313. In this embodiment, the operating part 4111 can be but is not limited to a handwheel, which is manually operated; the limiting protrusion 4113 is a limiting pin; in other embodiments, the operating part 4111 can be a limiting nut, which is fixedly sleeved on the rod 4112.

[0094] It is understandable that in other embodiments, such as during automated operations, the operating portion 4111 may be rotated by a driving mechanism such as a robot arm to drive the sliding member 412 to move along the second direction.

[0095] In this embodiment, a pressure-receiving member 421 is provided on the side of the floating member 42 facing the support member 31. A pressure-receiving inclined surface 4211 is provided on the side of the pressure-receiving member 421 facing the support member 31. A through slot 4212 extending in the second direction is formed on the side of the pressure-receiving member 421 facing the floating member 42. One end of the operating member 411, which is inserted through the connecting hole 4122, extends into the through slot 4212. With this arrangement, the operating member 411 is supported by the pressure-receiving member 421. Even if the sliding member 412 moves in the second direction and completely disengages from the pressure-receiving member 421, the sliding member 412 will not cause the operating member 411 to deviate, allowing the sliding member 412 to move back to the pressure-receiving member 421 along the operating member 411.

[0096] The operation process of the above-mentioned interchangeable positioning device 100 is roughly as follows:

[0097] The supporting member 32 of the interchangeable positioning device 100 is installed on the machine table of the processing device. When the workpiece needs to be processed, the interchangeable working platform 10 that carries and positions the workpiece is set on the supporting protrusion 212 of the supporting member 21, and the plug-in member 11 of the interchangeable working platform 10 is passed through the through hole 211 of the supporting member 21. Then, the operating member 411 is rotated to drive the floating member 42 to approach the supporting member 32 along the first direction, so that the floating member 42 drives the first clamping member 51 and the second clamping member 52 to move away from the supporting member 21 relative to the through opening 311 along the first direction, so that the first clamping end 511 and the second clamping end 521 are close to each other under the limit of the inner wall of the through opening 311 and clamp the annular groove 111 of the plug-in member 11, thereby realizing the positioning of the interchangeable working platform 10.

[0098] After the interchangeable work platform 10 is positioned, the workpiece is processed by the processing device. While processing the workpiece, another unprocessed workpiece can be installed on another interchangeable work platform 10. After the processing device completes processing the current workpiece, the operating member 411 is rotated in the opposite direction to drive the floating member 42 away from the supporting member 32 in the second direction, so that the floating member 42 drives the first clamping member 51 and the second clamping member 52 to move closer to the supporting member 21 relative to the through-hole 311 in the first direction, so that the first clamping end 511 and the second clamping end 521 are aligned with each other. Separate from the inner wall of the through-opening 311, and make the first clamping end 511 and the second clamping end 521 move away from each other under the action of the clamping elastic member 53 and release the inserting member 11, thereby canceling the positioning of the interchangeable work platform 10, and then hold the handle 12 of the interchangeable work platform 10 to remove the interchangeable work platform 10 that carries and positions the processed workpiece from the carrier 21, and set another interchangeable work platform 10 that carries and positions the unprocessed workpiece on the carrier 21, repeat the above actions to complete the processing of multiple workpieces.
