Description

Technical Field

[0001] This application relates to the field of workpiece clamping technology, specifically to a clamping device. Background Technology

[0002] In the field of workpiece clamping in machining, it is usually necessary to first position and fix the workpiece before performing cutting, milling, and other machining operations. Currently, for the clamping of tetrahedral workpieces, four lateral cylinders are typically used to simultaneously push the workpiece from all four sides to achieve clamping. However, due to the inherent deviation in the driving force of each cylinder, it is difficult to achieve a completely balanced pushing force on all four sides of the workpiece: if the pushing force on one or more sides is too large, it may cause plastic deformation or dimensional deviations in the workpiece; conversely, if the pushing force on one or more sides is insufficient, it may result in the workpiece not being able to be clamped tightly, causing displacement or vibration of the workpiece during machining, thereby reducing the machining accuracy of the workpiece. Utility Model Content

[0003] In view of the above, it is necessary to propose a clamping device to achieve stable clamping of the workpiece, ensure balanced force on all sides of the workpiece, and improve the machining accuracy of the workpiece.

[0004] This application provides a clamping device, including a carrying mechanism and a clamping mechanism; the carrying mechanism is used to carry a workpiece; the clamping mechanism includes a base plate, a slide block, a pushing member, a rotating member, and connecting rods. The base plate is disposed below the carrying mechanism. There are multiple slide blocks, which are evenly distributed around the periphery of the carrying mechanism, and each slide block is slidably disposed on the base plate. There are multiple pushing members, which are connected one-to-one with the multiple slide blocks, and the multiple pushing members are all located above the carrying mechanism. The rotating member is disposed on the base plate and located at the center position surrounded by the multiple slide blocks. There are multiple connecting rods, which are connected one-to-one with the multiple slide blocks, and both ends of each connecting rod are rotatably connected to the rotating member and the corresponding slide block, respectively.

[0005] In some embodiments, the clamping mechanism further includes a fixing member and a moving member, the sum of the number of the fixing member and the moving member being equal to the number of the slide and arranged opposite to each other, the fixing member being disposed on the bearing mechanism, the moving member being movably disposed on the bearing mechanism, and the slide pushing the moving member closer to the bearing mechanism when it approaches the bearing mechanism.

[0006] In some embodiments, the clamping mechanism further includes reset members, the number of which is equal to and corresponds one-to-one with the number of moving members, the reset members are disposed on the bearing mechanism, and the moving members are connected to the corresponding reset members.

[0007] In some embodiments, the clamping mechanism further includes a sensor switch disposed on the bearing mechanism and opposite to one of the moving members, the sensor switch being used to sense the corresponding moving member.

[0008] In some embodiments, the clamping device further includes a plurality of clamping mechanisms, which are evenly arranged around the periphery of the bearing mechanism. Each clamping mechanism includes a power component and a clamping component. The power component is disposed on the bearing mechanism, and the clamping component is connected to the power component and located above the bearing mechanism. The power component is used to drive the clamping component to rotate and move closer to or away from the bearing mechanism.

[0009] In some embodiments, each of the clamping mechanisms further includes a barb disposed on the corresponding clamping member and protruding toward the carrier mechanism from the corresponding clamping member, the barb being used to insert the workpiece when the clamping member is close to the carrier mechanism.

[0010] In some embodiments, the clamping device further includes a rotating mechanism disposed below and connected to the clamping mechanism, the rotating mechanism being used to drive the clamping mechanism and the bearing mechanism to rotate.

[0011] In some embodiments, the supporting mechanism includes a base plate and a carrier plate. The base plate is disposed above the substrate, and the carrier plate is disposed on the side of the base plate opposite to the substrate. A negative pressure groove is formed on the carrier plate. The carrier plate is used to support the workpiece, and the negative pressure groove is used to generate negative pressure to adsorb the workpiece.

[0012] In some embodiments, each of the slides includes a slider, a support, and a connector. The slider is slidably disposed on the substrate. The support is connected to the slider. The connector is connected to the support. The connector is located above the bearing mechanism. The pusher is connected to the connector. The connecting rod is rotatably connected to the slider.

[0013] In some embodiments, the clamping mechanism further includes slide rails and sliders. The number of slide rails is equal to and corresponds one-to-one with the number of slide blocks. The slide rails are disposed on the base plate. The number of sliders is equal to and corresponds one-to-one with the number of slide rails. The sliders are slidably disposed on the corresponding slide rails. The slide blocks are connected to the corresponding sliders.

[0014] When the above-mentioned clamping device is in use, if it is necessary to clamp the workpiece, the workpiece to be clamped is placed on the bearing mechanism. The rotating part of the clamping mechanism rotates and drives multiple connecting rods to rotate synchronously. The multiple connecting rods drive the corresponding multiple sliding blocks to slide synchronously closer to the bearing mechanism. The multiple sliding blocks drive the corresponding multiple pushing parts to move synchronously closer to the workpiece on the bearing mechanism, so that the multiple pushing parts push the workpiece from all sides of the workpiece simultaneously with a uniform pushing force, thereby clamping the workpiece for processing. When it is necessary to release the workpiece, the rotating part rotates in the opposite direction and drives multiple connecting rods to rotate synchronously in the opposite direction. The multiple connecting rods drive the corresponding multiple sliding blocks to move synchronously away from the bearing mechanism. The multiple sliding blocks drive the corresponding multiple pushing parts to move synchronously away from the workpiece on the bearing mechanism, so that the multiple pushing parts release the workpiece from all sides of the workpiece simultaneously, thereby releasing the workpiece for removal from the bearing mechanism.

[0015] The clamping device of this application embodiment drives multiple pushing members to simultaneously approach or move away from the workpiece through a rotating component. This transforms the rotational motion of the rotating component into the reciprocating linear motion of the multiple pushing members. The driving force and rotation angle of the rotating component are easily controlled, ensuring that the pushing force exerted by the multiple pushing members on each side of the workpiece is uniform. This results in balanced force on each side of the workpiece, preventing excessive pushing force on one or more sides that could lead to workpiece plastic deformation or dimensional errors, while also preventing insufficient pushing force on one or more sides that could prevent the workpiece from being properly clamped. This achieves stable clamping of the workpiece, preventing displacement or vibration during processing and improving the machining accuracy. Furthermore, driving multiple pushing members to simultaneously approach or move away from the workpiece through a single rotating component effectively saves equipment costs.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0022] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0023] Please see Figure 1 This application provides a clamping device 100. The clamping device 100 is used to clamp polyhedral workpieces (not shown in the figure). In this embodiment, the clamping device 100 is used to clamp tetrahedral workpieces. It is understood that in other embodiments, the clamping device 100 can also clamp trihedral, pentahedral, hexahedral, or more faceted workpieces, and this application does not specifically limit this.

[0024] Please refer to the above. Figure 2 The clamping device 100 includes a carrying mechanism 10 and a clamping mechanism 20. The carrying mechanism 10 is used to carry the workpiece, and the clamping mechanism 20 is used to clamp the workpiece carried on the carrying mechanism 10.

[0025] The clamping mechanism 20 includes a base plate 21, slide blocks 22, pushing members 23, rotating members 24, and connecting rods 25. The base plate 21 is disposed below the support mechanism 10, and its size is larger than that of the support mechanism 10. The support mechanism 10 and the base plate 21 are coaxially arranged. Multiple slide blocks 22 are evenly distributed around the periphery of the support mechanism 10, and each slide block 22 is slidably disposed on the base plate 21. Multiple pushing members 23 are connected one-to-one with each slide block 22, and are all located above the support mechanism 10. The rotating member 24 is disposed on the base plate 21 and located at the center of the multiple slide blocks 22 surrounding it; simultaneously, the rotating member 24 is also located at the center of the base plate 21. Multiple connecting rods 25 are connected one-to-one with each slide block 22, and both ends of each connecting rod 25 are rotatably connected to the rotating member 24 and the corresponding slide block 22, respectively. In this embodiment, there are four slide blocks 22, four pushing members 23, and four connecting rods 25. The four pushing members 23 abut against the workpiece from its four sides. The connecting rods 25 are generally arc-shaped, and their two ends are rotatably connected to the rotating member 24 and the corresponding slide block 22 via swing pins (not shown). It can be understood that when the clamping mechanism 20 clamps other polyhedral workpieces, the number of slide blocks 22, pushing members 23, and connecting rods 25 is equal to the number of sides of the polyhedral workpiece. This embodiment does not specifically limit this.

[0026] When clamping a tetrahedral workpiece, the clamping device 100, when clamping the workpiece, places the tetrahedral workpiece to be clamped on the bearing mechanism 10. The rotating component 24 of the clamping mechanism 20 rotates and drives the four connecting rods 25 to rotate synchronously. The four connecting rods 25 drive the corresponding four sliding blocks 22 to slide synchronously closer to the bearing mechanism 10. The four sliding blocks 22 drive the corresponding four pushing members 23 to move synchronously closer to the workpiece on the bearing mechanism 10, so that the four pushing members 23 push the workpiece from the four sides of the workpiece simultaneously with a uniform pushing force, thereby clamping the workpiece for processing. When it is necessary to release the workpiece, the rotating component 24 rotates in the opposite direction and drives the four connecting rods 25 to rotate synchronously in the opposite direction. The four connecting rods 25 drive the corresponding four sliding blocks 22 to move synchronously away from the bearing mechanism 10. The four sliding blocks 22 drive the corresponding four pushing members 23 to move synchronously away from the workpiece on the bearing mechanism 10, thereby releasing the workpiece from the four sides of the workpiece simultaneously, so that the workpiece can be removed from the bearing mechanism 10.

[0027] In this embodiment, the supporting mechanism 10 includes a base plate 11 and a carrier plate 12. The base plate 11 is disposed above the substrate 21, and the carrier plate 12 is disposed on the side of the base plate 11 opposite to the substrate 21. A negative pressure groove 121 is formed on the carrier plate 12. The negative pressure groove 121 can be a mesh groove structure. The negative pressure groove 121 is used to communicate with an external negative pressure device (not shown). The carrier plate 12 is used to support the workpiece, and the negative pressure groove 121 is used to generate negative pressure under the action of the external negative pressure device to adsorb the workpiece. In this way, by setting the carrier plate 12 and the negative pressure groove 121, the workpiece can be stably attached to the carrier plate 12, preventing the workpiece from shaking on the carrier plate 12.

[0028] In this embodiment, mounting portions 111 protrude from the four corners of the base plate 11. The supporting mechanism 10 also includes four connecting posts 13, each corresponding to one of the four mounting portions 111. Both ends of each connecting post 13 are connected between the corresponding mounting portion 111 and the base plate 21. Thus, by providing the mounting portions 111 and connecting posts 13, the base plate 11 and the base plate 21 are connected, ensuring a stable connection between the supporting mechanism 10 and the clamping mechanism 20. It is understood that in other embodiments, the number of mounting portions 111 and connecting posts 13 may be more or fewer, depending on the actual situation.

[0029] In this embodiment, each slide 22 includes a slider 221, a support 222, and a connector 223. The slider 221 is slidably disposed on the base plate 21, the support 222 is connected to the slider 221, and the connector 223 is connected to the support 222. The connector 223 is located above the support mechanism 10. The pusher 23 is connected to the connector 223, and the connecting rod 25 is rotatably connected to the slider 221. Thus, by setting the specific structure of the slide 22, the pusher 23 can be located above the support mechanism 10.

[0030] In this embodiment, the clamping mechanism 20 further includes slide rails 29 and sliders 295. The number of slide rails 29 is equal to and corresponds one-to-one with the number of slide blocks 22. The slide rails 29 are disposed on the base plate 21. The number of sliders 295 is equal to and corresponds one-to-one with the number of slide rails 29. The sliders 295 are slidably disposed on the corresponding slide rails 29. The sliding member 221 of the slide block 22 is connected to the corresponding slider 295. In this embodiment, there are four slide rails 29 and four sliders 295. Thus, by setting the slide rails 29 and sliders 295, the slide block 22 is slidably disposed on the base plate 21 via the slide rails 29 and sliders 295, while ensuring the movement accuracy of the slide block 22 and preventing the slide block 22 from shifting.

[0031] To prevent the pushing member 23 from scratching or abrading the workpiece, in this embodiment, an upper flexible strip 231 is provided on the top side of the pushing member 23, and a side flexible strip 232 is provided on the side side of the pushing member 23. The upper flexible strip 231 and the side flexible strip 232 can be made of rubber, urethane, or other elastic materials. Thus, by providing the upper flexible strip 231 on the top side of the pushing member 23, the workpiece is prevented from being scratched or abraded due to hard contact with the pushing member 23 when placed onto the bearing mechanism 10; the workpiece will also not be scratched or abraded when in contact with the upper flexible strip 231. By providing the side flexible strip 232 on the side side of the pushing member 23, the pushing member 23 can make flexible contact with the workpiece.

[0032] In this embodiment, the rotating component 24 includes a rotary cylinder 241, a disc 242, an assembly plate 243, and support columns 244. The assembly plate 243 is disposed below the base plate 21. Four support columns 244 are spaced apart at the four corners of the assembly plate 243 and are connected between the base plate 21 and the assembly plate 243. The rotary cylinder 241 is mounted on the assembly plate 243, and the disc 242 is rotatably mounted on the base plate 21 and connected to the rotary cylinder 241. The disc 242 is rotatably connected to connecting rods 25. The rotary cylinder 241 drives the disc 242 to rotate, thereby causing the disc 242 to drive multiple connecting rods 25 to rotate synchronously. Thus, by setting the specific structure of the rotating component 24, the installation and driving of multiple connecting rods 25 are achieved.

[0033] In this embodiment, the clamping mechanism 20 further includes a fixing member 26 and a moving member 27. The total number of fixing members 26 and moving members 27 is equal to the number of slides 22 and they are arranged opposite to each other. Alternatively, the total number of fixing members 26 and moving members 27 can be understood as equal to the number of faces of a polyhedral workpiece. The fixing members 26 are fixedly mounted on the support mechanism 10, and the moving members 27 are movably mounted on the support mechanism 10. When the slides 22 approach the support mechanism 10, they push the moving members 27 closer to the support mechanism 10. In this embodiment, there are two fixing members 26 and two moving members 27. The two fixing members 26 are fixedly mounted on the base plate 11 of the support mechanism 10 and respectively abut against adjacent sides of the carrier plate 12. The two moving members 27 are movably mounted on the base plate 11 of the support mechanism 10 and respectively located on another adjacent side of the carrier plate 12.

[0034] Thus, by setting the aforementioned fixing members 26 and moving members 27, when clamping a workpiece, the clamping device 100 places the workpiece on the carrier plate 12, and makes the adjacent sides of the workpiece abut against the two fixing members 26 respectively. The rotating member 24 drives the multiple sliding blocks 22 to move towards the bearing mechanism 10 through multiple connecting rods 25. The support members 222 of the two sliding blocks 22 push the corresponding two moving members 27 closer to the bearing mechanism 10, so that the two moving members 27 abut against the other adjacent sides of the workpiece. The two moving members 27 cooperate with the two fixing members 26 to clamp the workpiece. It can be understood that the four pushing members 23 are used to clamp the upper side of the workpiece, and the two fixing members 26 and the two moving members 27 cooperate to clamp the lower side of the workpiece.

[0035] Understandably, in other embodiments, the number of fixing members 26 may be one or three, and the number of moving members 27 may be three or one, depending on the actual situation.

[0036] Understandably, when the clamping mechanism 20 clamps other polyhedral workpieces, the number of fixed parts 26 and movable parts 27 can be adaptively increased or decreased, and the embodiments of this application do not specifically limit this.

[0037] To prevent the fastener 26 from scratching or damaging the workpiece, in this embodiment, an upper anti-collision strip 261 is provided on the top side of the fastener 26, and a side anti-collision strip 262 is provided on the side of the fastener 26. The upper anti-collision strip 261 and the side anti-collision strip 262 can be made of rubber, urethane, or other elastic materials. Thus, by providing the upper anti-collision strip 261 on the top side of the fastener 26, the workpiece is prevented from being scratched or damaged due to hard contact with the fastener 26 when it is placed on the bearing mechanism 10; the workpiece will also not be scratched or damaged when it comes into contact with the upper anti-collision strip 261. By providing the side anti-collision strip 262 on the side of the fastener 26, the fastener 26 makes flexible contact with the workpiece.

[0038] To enable the movable component 27 to reset, in this embodiment, the clamping mechanism 20 further includes a reset component 275. The number of reset components 275 is equal to the number of movable components 27 and corresponds one-to-one. The reset components 275 are disposed on the bearing mechanism 10, and the movable component 27 is connected to the corresponding reset component 275. In this embodiment, the reset component 275 can be a linear cylinder, and there are two reset components 275, which are disposed on the side of the base plate 11 away from the carrier plate 12. Thus, by providing the aforementioned reset components 275, when the slide 22 moves away from the bearing mechanism 10, the reset component 275 drives the movable component 27 to reset, so that the movable component 27 can release the workpiece. It is understood that in other embodiments, the reset component 275 can also be a spring, which is embedded in the side of the base plate 11 and connected to the movable component 27, and the movable component 27 is reset by the spring force. This embodiment will not be described in detail here.

[0039] In this embodiment, the clamping mechanism 20 further includes a sensor switch 28. The sensor switch 28 is disposed on the bearing mechanism 10 and opposite to one of the moving parts 27. The sensor switch 28 is used to sense the corresponding moving part 27. The sensor switch 28 can be electrically connected to an external negative pressure device. When the sensor switch 28 senses the corresponding moving part 27, the external negative pressure device is activated to generate negative pressure in the negative pressure groove 121 of the carrier plate 12, thereby adsorbing the workpiece. In this embodiment, the sensor switch 28 can be a pneumatic limit switch. Thus, by setting the aforementioned sensor switch 28, when the sensor switch 28 senses the corresponding moving part 27, i.e., when the moving part 27 and the fixing part 26 clamp the workpiece, and the pushing part 23 also clamps the workpiece, the external negative pressure device is activated to generate negative pressure in the negative pressure groove 121, thereby adsorbing the workpiece. When the moving part 27 releases the workpiece, the sensor switch 28 no longer senses the corresponding moving part 27, and the external negative pressure device is closed. This allows the workpiece to fit more closely to the carrier plate 12, saves air supply, and reduces costs.

[0040] Understandably, in other embodiments, the inductive switch 28 may also be a distance sensor or other functional object with sensing function, and this application embodiment does not specifically limit it in this way.

[0041] In this embodiment, the clamping device 100 further includes multiple clamping mechanisms 30. These clamping mechanisms 30 are evenly distributed around the periphery of the supporting mechanism 10. Specifically, in this embodiment, there are four clamping mechanisms 30, each mounted on one of the four mounting portions 111 of the base plate 11. Each clamping mechanism 30 includes a power component 31 and a clamping component 32. The power component 31 is mounted on the corresponding mounting portion 111 of the base plate 11 of the supporting mechanism 10. The clamping component 32 is connected to the power component 31 and located above the supporting mechanism 10. The power component 31 drives the clamping component 32 to rotate and move closer to or away from the supporting mechanism 10. The power component 31 can be a rotary lifting cylinder. Thus, by configuring the clamping mechanisms 30 and their specific structures, after the clamping mechanism 20 clamps the workpiece, the power component 31 drives the clamping component 32 to rotate and move closer to the workpiece on the supporting mechanism 10, causing the clamping component 32 to press against the workpiece, thereby further fixing the workpiece.

[0042] To improve the adaptability of the clamping device 100, in this embodiment, each clamping mechanism 30 further includes a barb 33. The barb 33 is disposed on the corresponding clamping member 32 and protrudes from the corresponding clamping member 32 toward the bearing mechanism 10. The barb 33 is used to insert into the workpiece on the bearing mechanism 10 when the clamping member 32 is close to the bearing mechanism 10. Thus, by providing the above-mentioned barb 33, when the clamping device 100 clamps a workpiece with an opening, the barb 33 is inserted into the opening of the workpiece to hook the side wall of the workpiece, thereby fixing the workpiece and improving the adaptability of the clamping device 100.

[0043] In this embodiment, the clamping device 100 further includes a rotating mechanism 40. The rotating mechanism 40 is located below and connected to the clamping mechanism 20. The rotating mechanism 40 drives the clamping mechanism 20 and the supporting mechanism 10 to rotate. Specifically, the rotating mechanism 40 is connected to the mounting plate 243 of the rotating component 24. The rotating mechanism 40 can be a CNC (Computer Numerical Control) machine tool or other functional mechanisms with rotation capabilities. Thus, by providing the aforementioned rotating mechanism 40, after the clamping mechanism 20 and the clamping mechanism 30 fix the workpiece, the rotating mechanism 40 can drive the clamping mechanism 20, the supporting mechanism 10, and the clamping mechanism 30 to rotate, facilitating the processing of the workpiece at various angles and improving the adaptability of the clamping device 100.

[0044] In use, the clamping device 100 provided in this embodiment is first assembled according to the number of faces of the workpiece. Next, the workpiece is placed on the carrier plate 12 of the supporting mechanism 10. Then, the rotary cylinder 241 of the rotating member 24 drives the disc 242 to rotate, the disc 242 drives the connecting rod 25 to rotate, the connecting rod 25 drives the slide 22 to move along the slide rail 29, and the slide 22 drives the pushing member 23 to move towards the workpiece, clamping the workpiece with the cooperation of the pushing member 23. Simultaneously, as the slide 22 drives the pushing member 23 to move towards the workpiece, the slide 22 pushes the moving member 27 towards the workpiece, clamping the workpiece with the cooperation of the moving member 27 and the fixing member 26. Then, when the moving member 27 clamps the workpiece, the inductive switch 28 senses the moving member 27, and the external negative pressure device is activated to generate negative pressure in the negative pressure groove 121 of the carrier plate 12 to adsorb the workpiece. Finally, the clamping mechanism 30 clamps the workpiece, thereby fixing it in place. The workpiece can then be processed in conjunction with the rotating mechanism 40. After processing, the rotary cylinder 241 drives the disc 242 to rotate in the opposite direction, causing the pushing member 23 and the moving member 27 to release the workpiece. Simultaneously, the external negative pressure device closes, eliminating the negative pressure in the negative pressure groove 121. The clamping mechanism 30 then releases the workpiece, allowing it to be removed from the carrier plate 12.

[0045] The clamping device 100 provided in this embodiment has a simple structure. A single rotating component 24 drives multiple pushing components 23 to simultaneously approach or move away from the workpiece, transforming the rotational motion of the rotating component 24 into the reciprocating linear motion of the multiple pushing components 23. The driving force and rotation angle of the rotating component 24 are easily controlled, ensuring that the pushing force exerted by the multiple pushing components 23 on each side of the workpiece is uniform. This results in balanced force on each side of the workpiece, preventing excessive pushing force on one or more sides that could lead to workpiece deformation or dimensional errors, while also preventing insufficient pushing force on one or more sides that would prevent the workpiece from being properly clamped. This achieves stable clamping of the workpiece, preventing displacement or vibration during processing and improving workpiece machining accuracy. Furthermore, driving multiple pushing components 23 to simultaneously approach or move away from the workpiece via a single rotating component 24 effectively saves equipment costs.

[0046] The clamping device 100 provided in this embodiment further fixes the workpiece through the cooperation of the clamping mechanism 30, thereby improving the adaptability of the clamping device 100. The clamping device 100 provided in this embodiment further utilizes the cooperation of the rotating mechanism 40, which drives the clamping mechanism 20, the bearing mechanism 10, and the clamping mechanism 30 to rotate, facilitating the processing of the workpiece at various angles and further improving the adaptability of the clamping device 100.
