Abstract

Technical Field
[0001] The present application relates to the technical field of product clamping, and in particular to a clamping device. Background Art
[0002] In actual production and processing, thin products often need to be machined on their sidewalls. Currently, jigs are typically used to position thin products. However, when jigs are used to position thin products, a portion of the product's sidewalls is blocked by the jig, making them impossible to machine. After machining the unobstructed sidewalls with a tool, the jig is then used to position the thin product a second time, allowing the unmachined sidewalls to be machined.

[0068] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.
[0069] See Figure 1 , the embodiment of the present application provides a clamping device 100. Please refer to Figure 2 and Figure 3 The clamping device 100 is used to clamp the product 200, wherein the product 200 can be a thin plate-shaped object. After the clamping device 100 clamps the product 200, a tool (not shown) is used to process all side walls of the product 200. The product 200 is clamped once so that all side walls of the product 200 can be processed. Figure 2 The dotted area shown generally represents the general shape of the processed product 200. For ease of understanding and explanation, the present embodiment defines Figure 1 The XYZ coordinate system shown, wherein the X-axis direction is the first direction, the Y-axis direction is the third direction, and the Z-axis direction is the second direction. It can be understood that this is not a limitation of the embodiments of the present application.
[0070] The clamping device 100 includes a base 10, a supporting assembly 20, a clamping mechanism 30 and a pressure plate assembly 40. The base 10 is used to install the supporting assembly 20, the clamping mechanism 30 and the pressure plate assembly 40, so that the clamping device 100 can be modularly set up. The clamping device 100 can also be installed on an external machine (not shown) to improve the versatility of the clamping device 100.
[0071] The carrying assembly 20 is disposed on the base 10 , and is used to carry the product 200 . The carrying assembly 20 protrudes from the base 10 along the second direction.
[0072] The clamping mechanism 30 includes two driving components 31 and two clamping members 32. The two driving components 31 are respectively arranged on opposite sides of the base 10 along the first direction. The two clamping members 32 are connected to the two driving components 31 one by one. The two clamping members 32 are spaced apart from the base 10 along a second direction perpendicular to the first direction. The two driving components 31 are used to drive the two clamping members 32 to approach or move away from each other along the first direction, and to drive the two clamping members 32 to approach or move away from the base 10 along the second direction. It can also be understood that the two driving components 31 drive the two clamping members 32 to approach or move away from the supporting component 20 along the second direction.
[0073] The pressure plate assembly 40 and the carrier assembly 20 are spaced apart along the second direction and located between the two clamping members 32. The pressure plate assembly 40 is used to be detachably connected to the two clamping members 32 when the two clamping members 32 approach each other along the first direction, and to approach and abut the product 200 carried by the carrier assembly 20 when the two clamping members 32 approach the base 10 along the second direction. A magnetic attraction force can be generated between the pressure plate assembly 40 and the carrier assembly 20, so that the pressure plate assembly 40 presses the product 200 against the carrier assembly 20.
[0074] The cross-sectional area of the load-bearing component 20 perpendicular to the second direction and the cross-sectional area of the pressure plate component 40 perpendicular to the second direction are both smaller than the cross-sectional area of the product 200 perpendicular to the second direction. It can be understood that after all side walls of the product 200 are processed, the cross-sectional area of the load-bearing component 20 perpendicular to the second direction and the cross-sectional area of the pressure plate component 40 perpendicular to the second direction are still smaller than the cross-sectional area of the product 200 perpendicular to the second direction.
[0075] When the clamping device 100 is actually used, Figure 1 In the initial state shown, the pressure plate assembly 40 is detachably connected to the two clamping members 32 and is driven by the two driving assemblies 31 to move away from the base 10 and the carrying assembly 20 in the second direction, so as to leave space for placing the product 200 on the carrying assembly 20. The product 200 to be processed is placed on the carrying assembly 20, and the two driving assemblies 31 drive the two clamping members 32 and the pressure plate assembly 40 to approach the base 10 and the carrying assembly 20 in the second direction, so that the pressure plate assembly 40 approaches and abuts against the product 200 carried by the carrying assembly 20, and through the magnetic attraction between the pressure plate assembly 40 and the carrying assembly 20, the pressure plate assembly 40 presses the product 200 against the carrying assembly 20, thereby achieving clamping and fixing of the product 200. When the product 200 is pressed against the carrying assembly 20 by the pressure plate assembly 40, the two driving assemblies 31 drive the two clamping members 32 to move away from each other in the first direction, so that the two clamping members 32 are separated from the pressure plate assembly 40 and both are away from the pressure plate assembly 40, as shown in FIG. Figure 3In the clamping state shown, when both clamping members 32 are away from the pressure plate assembly 40, the side wall of the product 200 is processed by the tool. Since the cross-sectional area of the bearing assembly 20 perpendicular to the second direction and the cross-sectional area of the pressure plate assembly 40 perpendicular to the second direction are both smaller than the cross-sectional area of the product 200 perpendicular to the second direction, when the tool processes the side wall of the product 200, the bearing assembly 20 and the pressure plate assembly 40 will not interfere with the tool when processing the side wall of the product 200, so that the tool can process all the side walls of the product 200. The side walls are processed. After the tool has processed all the side walls of the product 200, the two driving assemblies 31 drive the two clamping members 32 to approach each other in the first direction, so that the two clamping members 32 are detachably connected to the pressure plate assembly 40. When the two clamping members 32 are detachably connected to the pressure plate assembly 40, the magnetic attraction between the pressure plate assembly 40 and the bearing assembly 20 disappears, and the two driving assemblies 31 drive the two clamping members 32 and the pressure plate assembly 40 away from the base 10 and the bearing assembly 20 in the second direction, so as to facilitate the removal of the processed product 200. Figure 1 In the initial state shown, after the processed product 200 is taken out, the product 200 to be processed can be placed again, and the product 200 can be processed in this cycle.
[0076] Please refer to Figure 4 In this embodiment, the base 10 includes a bottom plate 11, a top plate 12, a first side plate 13, and a second side plate 14. The bottom plate 11 and the top plate 12 are spaced apart along the second direction. The number of the first side plates 13 and the number of the second side plates 14 are both two. The two first side plates 13 are spaced apart along the first direction and are both connected between the bottom plate 11 and the top plate 12. The two second side plates 14 are spaced apart along a third direction perpendicular to both the first and second directions and are both connected between the bottom plate 11 and the top plate 12. The two second side plates 14 are also connected between the two first side plates 13. The bearing assembly 20 is disposed on the top plate 12, and the two driving assemblies 31 are respectively disposed on the two first side plates 13. In this way, by setting the specific structure of the base 10 described above, the structure of the base 10 is simple and stable, and the bearing assembly 20 and the clamping mechanism 30 can be stably installed, thereby improving the structural stability of the clamping device 100.
[0077] In this embodiment, the supporting assembly 20 includes a base 21 and a magnet 22. The base 21 is provided on the base 10 and has an embedding hole 212. The magnet 22 is embedded in the embedding hole 212. The magnet 22 can generate a magnetic attraction force to generate a magnetic attraction force between the pressure plate assembly 40. The magnet 22 and the base 21 together support the product 200. Specifically, the top plate 12 has an embedding hole 121. The base 21 is provided on the top plate 12 and the embedding hole 121 is connected to the embedding hole 212. The magnet 22 is embedded in the embedding hole 121 and the embedding hole 212. The magnet 22 can generate a magnetic force. In this way, by setting the specific structure of the supporting assembly 20, the magnet 22 of the supporting assembly 20 can generate a magnetic force to generate a magnetic attraction force between the pressure plate assembly 40.
[0078] It is understandable that in other embodiments, the pressure plate assembly 40 may be configured to include a magnetic attractor 22 , and the pressure plate assembly 40 may generate magnetic force to generate magnetic attraction force with the supporting assembly 20 .
[0079] In this embodiment, each driving component 31 includes a first driving member 311, a slide 312, a slide rod 313 and a second driving member 314. The first driving member 311 and the second driving member 314 can both be linear cylinders. The first driving member 311 is arranged on the base 10, the slide 312 is spaced apart from the base 10 along the first direction and is connected to the first driving member 311, one end of the slide rod 313 is connected to the slide 312, and the other end of the slide rod 313 is slidably passed through the base 10, the first driving member 311 is used to drive the slide 312 to move along the first direction, the second driving member 314 is connected to the slide 312 and follows the slide 312 to move along the first direction, and the second driving member 314 is connected to the corresponding clamping member 32 to drive the corresponding clamping member 32 to move along the second direction. In this way, by setting the specific structure of the above-mentioned driving component 31, the first driving member 311 drives the slide 312, the second driving member 314 and the clamping member 32 to move along the first direction, so as to drive the clamping member 32 to move along the first direction, and the second driving member 314 drives the clamping member 32 to move along the second direction, so as to drive the clamping member 32 to move along the second direction.
[0080] Specifically, in this embodiment, each driving assembly 31 further includes a mounting plate 315 and a linear sleeve 316. The mounting plate 315 is provided on the base plate 11 and is located between the two first side plates 13. The first driving member 311 is provided on the mounting plate 315. The first side plate 13 is provided with a avoidance hole 131 for avoiding the first driving member 311. The slide 312 and the second driving member 314 are both located on the outside of the base 10. The number of sliding rods 313 and the number of linear sleeves 316 are both two and correspond one to one. The two linear sleeves 316 are both provided on the corresponding first side plate 13 and are respectively located on both sides of the avoidance hole 131. One end of the two sliding rods 313 is connected to the slide 312, and the other end of the two sliding rods 313 is respectively slidably connected to the corresponding linear sleeve 316, so that the sliding rod 313 can achieve a sliding connection with the first side plate 13. Thus, by setting the specific structure of the driving assembly 31, the driving assembly 31 is easy to install, and the two slide rods 313 and the two linear bushings 316 ensure the stability of the slide 312, the second driving member 314 and the clamping member 32 when moving along the first direction.
[0081] In this embodiment, the pressure plate assembly 40 includes a pressure plate 41 and a plurality of connecting members 42. The pressure plate 41 and the load-bearing assembly 20 are spaced apart along the second direction and are located between the two clamping members 32. The plurality of connecting members 42 are respectively arranged at opposite ends of the pressure plate 41 along the first direction, and the plurality of connecting members 42 are all located on the side of the pressure plate 41 away from the load-bearing assembly 20. Each clamping member 32 is provided with an opening 321 adapted to the connecting member 42 on the side facing the pressure plate 41. Each clamping member 32 is detachably connected to the pressure plate assembly 40 by snapping together with the connecting member 42 through the corresponding opening 321. Specifically, in this embodiment, the number of connecting members 42 can be four, and each connecting member 42 can be roughly T-column-shaped. Two connecting members 42 are respectively provided at opposite ends of the pressure plate 41, and each clamping member 32 is provided with two openings 321. The pressure plate 41 can be made of plastic steel, and magnetic force can be generated between the pressure plate 41 and the magnetic absorber 22. In this way, when the two clamping members 32 approach each other along the first direction under the drive of the two driving assemblies 31, the opening 321 of the clamping member 32 is engaged with the corresponding connecting member 42, thereby realizing a detachable connection between the clamping member 32 and the pressure plate assembly 40. When the two clamping members 32 move away from each other along the first direction under the drive of the two driving assemblies 31, the opening 321 of the clamping member 32 is separated from the corresponding connecting member 42, thereby realizing the separation of the clamping member 32 and the pressure plate assembly 40.
[0082] It can be understood that in other embodiments, the number of connecting parts 42 can be more or less, such as two, three, five, six, etc. The number of connecting parts 42 set at the opposite ends of the pressure plate 41 can be equal or unequal, and the number and position of the openings 321 on the clamping part 32 are adaptively set, and the embodiments of the present application do not make specific limitations on this.
[0083] See Figure 5 In this embodiment, the pressure plate assembly 40 may further include a flexible member 43. The flexible member 43 is generally annular and is disposed on the side of the pressure plate 41 facing the load-bearing assembly 20. The flexible member 43 is elastic. The flexible member 43 may be made of an elastic material such as rubber or elastomeric. Thus, by providing the flexible member 43, the pressure plate assembly 40 flexibly contacts the product 200 through the flexible member 43, thereby preventing the product 200 from being crushed.
[0084] In this embodiment, the clamping device 100 may further include a plurality of debugging pins 45, a plurality of debugging holes 411 are provided on the periphery of the pressure plate 41, and a plurality of insertion holes 211 are provided on the periphery of the carrier assembly 20, specifically, a plurality of insertion holes 211 are provided on the periphery of the base 21. The plurality of debugging pins 45, the plurality of debugging holes 411, and the plurality of insertion holes 211 are provided in a one-to-one correspondence, and each debugging pin 45 is used to sequentially pass through the corresponding debugging hole 411, the flexible member 43, and the corresponding insertion hole 211 to position the pressure plate assembly 40 and the carrier assembly 20. The debugging holes 411 can be provided at the four corners of the pressure plate 41, and the insertion holes 211 can be provided at the four corners of the base 21. When positioning the pressure plate assembly 40 and the carrier assembly 20, two debugging pins 45 can be inserted into two diagonally arranged debugging holes 411 and two insertion holes 211 to position the pressure plate assembly 40 and the carrier assembly 20. Thus, before officially clamping the product 200, the debugging pin 45 can be sequentially inserted into the corresponding debugging hole 411, the flexible member 43, and the corresponding insertion hole 211 to ensure the relative position accuracy between the pressure plate assembly 40 and the carrier assembly 20. Then, the drive assembly 31 can be debugged to ensure that the drive assembly 31 and the pressure plate assembly 40 can be accurately and detachably connected, ensuring that the clamping member 32 can be accurately and detachably connected to the pressure plate assembly 40, and ensuring that the pressure plate assembly 40 can accurately abut the product 200 on the carrier assembly 20, thereby improving the accuracy of the clamping device 100 in clamping the product 200. It can be understood that the debugging pin 45 is not used when officially clamping the product 200.
[0085] It is understandable that the socket 211 on the base 21 can also be used to achieve a positioning connection with the top plate 12 of the base 10 .
[0086] In this embodiment, the clamping device 100 further includes a positioning mechanism 50 for positioning the product 200. The positioning mechanism 50 includes a plurality of first positioning pins 51, a plurality of first power sources 52, a plurality of second positioning pins 53, and a plurality of second power sources 54. The plurality of first positioning pins 51 are each retractably disposed on the top plate 12 of the base 10 along the second direction. A portion of the first positioning pins 51 are located on opposite sides of the support assembly 20 along the first direction, while another portion of the first positioning pins 51 are located on one side of the support assembly 20 along a third direction perpendicular to both the first and second directions. The plurality of first power sources 52 are each disposed on the top plate 12 of the base 10 and connected one-to-one with the plurality of first positioning pins 51. The plurality of first power sources 52 are each located between the bottom plate 11 and the top plate 12. Each first power source 52 is configured to drive a corresponding first positioning pin 51 to move along the second direction so as to retract within the base 10. The plurality of second positioning pins 53 are all retractably arranged on the base 10 along the second direction. The plurality of second positioning pins 53 are arranged according to the positioning holes 201 on the product 200 (see Figure 2 As shown) is adapted to be located on the peripheral side of the supporting assembly 20, each second power source 54 is arranged on the top plate 12 of the base 10 and is connected one-to-one with multiple second positioning pins 53, and multiple second power sources 54 are all located between the bottom plate 11 and the top plate 12, and each second power source 54 is used to drive the corresponding second positioning pin 53 to move along the second direction to retract into the base 10.
[0087] In this way, by setting the above-mentioned first positioning pin 51, multiple first positioning pins 51 located on three sides of the supporting component 20 position the product 200 in the first direction and the third direction, and one side is reserved for placing the product 200 on the supporting component 20, and by setting the above-mentioned second positioning pin 53, the second positioning pin 53 is adapted to be inserted into the positioning hole 201 of the product 200 to accurately position the product 200. By setting the above-mentioned first power source 52 and second power source 54, when the tool processes the side wall of the product 200, the first power source 52 and the second power source 54 respectively drive the corresponding first positioning pin 51 and the second positioning pin 53 to move along the second direction to retract into the base 10, thereby avoiding interference between the first positioning pin 51 and the second positioning pin 53 and the tool, thereby ensuring smooth processing of the tool.
[0088] Specifically, in this embodiment, there are four first positioning pins 51 and four first power sources 52. Two first positioning pins 51 are disposed on opposite sides of the support assembly 20 along the first direction, and two other first positioning pins 51 are disposed on one side of the support assembly 20 along the third direction. These four first positioning pins 51 position the product 200 on three sides. There are three second positioning pins 53 and three second power sources 54. The three second positioning pins 53 are disposed on opposite sides of the support assembly 20 along the first direction. Both the first power source 52 and the second power source 54 may be pneumatic cylinders.
[0089] It can be understood that in other embodiments, the number of the first positioning pin 51, the first power source 52, the second positioning pin 53 and the second power source 54 can be more or less, and can be set according to actual conditions. The embodiments of the present application do not make specific limitations on this.
[0090] It is understandable that when there is no positioning hole 201 on the product 200 , the second positioning pin 53 and the second power source 54 can be omitted, or the second positioning pin 53 can be retracted into the base 10 under the drive of the second power source 54 .
[0091] It is understood that the clamping device 100 may further include an electronic control module (not shown), which is used to connect to the drive assembly 31, the first power source 52, the second power source 54, and the magnetic absorber 22. The electronic control module is used to control the start and stop of the drive assembly 31, the first power source 52, the second power source 54, and the magnetic absorber 22, thereby automating the clamping device 100. The electronic control module may be composed of components such as a negative pressure gauge, a pressure regulating valve, and a solenoid valve, and the embodiments of the present application will not be described in detail here.
[0092] In this embodiment, the clamping device 100 further includes a chip guard 60. The chip guard 60 is disposed on one or both sides of the base 10 along a first direction and spaced apart from the support assembly 20 along the first direction. Alternatively, the chip guard 60 is disposed on one or both sides of the base 10 along a third direction perpendicular to both the first and second directions and spaced apart from the support assembly 20 along the third direction. Thus, the chip guard 60 prevents debris generated by the machining of the product 200 from flying when the tool is machining the sidewalls of the product 200. The chip guard 60 can be made of, for example, acrylic.
[0093] Specifically, there can be two chip guards 60, each of which is disposed on the two first side panels 13 of the base 10 and spaced apart from the carrier assembly 20 along the first direction. Furthermore, when the clamping member 32 moves toward the base 10 along the second direction, the chip guards 60 also function to stop and limit the clamping member 32, preventing the drive assembly 31 from causing the clamping member 32 and the pressure plate assembly 40 to move excessively and potentially damage the product 200.
[0094] In this embodiment, the clamping device 100 further includes a transport member 70, which is connected to one or both sides of the base 10 along the first direction, and / or connected to one or both sides of the base 10 along a third direction perpendicular to both the first and second directions. Thus, the transport member 70 facilitates transport of the clamping device 100. Specifically, there can be four transport members 70, each of which can be a screw, and the four transport members 70 are respectively disposed on the two first side panels 13.
[0095] The clamping device 100 provided in the embodiment of the present application, through the coordinated cooperation of the base 10, the supporting assembly 20, the clamping mechanism 30 and the pressure plate assembly 40, clamps the product 200 once so as to facilitate the processing of all side walls of the product 200. Since all side walls of the product 200 can be processed at one time, the problem of poor knife marks caused by processing the side walls of the product 200 in batches can be solved. In addition, since the product 200 is clamped once so as to facilitate the processing of all side walls of the product 200, the number of clamping and processing times of the product 200 is reduced, the time required for clamping and processing is saved, which is conducive to improving the clamping and processing efficiency of the product 200.
[0096] The clamping device 100 provided in the embodiment of the present application further cooperates with the positioning mechanism 50 to, on the one hand, achieve positioning of the product 200, and, on the other hand, avoid interference when the tool processes the product 200 on the basis of achieving positioning of the product 200.
[0097] The clamping device 100 provided in the embodiment of the present application further cooperates with the chip prevention plate 60. On the one hand, it can prevent the debris generated by the processed product 200 from flying. On the other hand, it also has the function of stopping and limiting the clamping member 32 to prevent the driving component 31 from driving the clamping member 32 and the pressure plate assembly 40 to move excessively and crush the product 200.
