[0034] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0035] According to one embodiment of the present application, a clamping device is provided. Figures 1 to 6 As shown, the clamping device includes: a first bracket 5 and a plurality of elastic pressure components 4. The plurality of elastic pressure components 4 are connected to the first bracket 5 at intervals, and the first bracket 5 is suitable for driving the plurality of elastic pressure components 4 to press the workpiece 2. The clamping device of the present application presses the workpiece 2 by means of the plurality of elastic pressure components 4, and can adapt to the structure of different areas of the workpiece 2, so that the pressing force on each part of the workpiece 2 remains stable and more uniform.

[0036] In a specific embodiment of the present application, the first bracket 5 can drive multiple elastic pressure components 4 to press the workpiece 2. That is, multiple elastic pressure components 4 can press different parts of the workpiece 2. By pressing the workpiece with multiple elastic pressure components, the structure of different areas of the workpiece can be adapted, so that the pressing force on each part of the workpiece remains stable and more uniform.

[0037] For example, the clamping device can be used to maintain pressure on a workpiece, and the glue pressing structure of the workpiece 2 has a raised area or a recessed area. When the first bracket 5 drives multiple elastic pressure components 4 to press the workpiece 2, some elastic pressure components 4 are pressed on the raised area, and some elastic pressure components 4 are pressed on the recessed area. The elastic pressure components 4 in different areas can be adaptively extended or shortened to maintain stable pressure on various areas of the workpiece 2, and the pressing force at each location is relatively uniform, so as to improve the pressure-maintaining effect on the workpiece 2.

[0038] The workpiece 2 may be a pallet and a composite board bonded together after gluing, and the multiple elastic pressure components 4 may adapt to the structure of different areas of the pallet to improve the bonding effect of the pallet and the composite board. Of course, the workpiece 2 of the present application may also be other types of workpieces, and those skilled in the art may determine according to actual conditions, and no specific limitation is made here.

[0039] In a specific embodiment of the present application, a plurality of elastic pressure components 4 are arranged at intervals on the first bracket 5, and the positions of the plurality of elastic pressure components 4 are located on the same plane, so as to apply a more uniform force to the workpiece 2. The elastic pressure component 4 can be connected to the first bracket 5 by fasteners such as bolts or studs, or can be connected to the first bracket 5 by welding or bonding, or can be connected to the first bracket 5 by snapping. Those skilled in the art can determine according to actual conditions, and no specific limitation is made here.

[0040] In a specific embodiment of the present application, the clamping device further includes a second bracket 1, and the workpiece 2 is placed on the second bracket 1. The second bracket 1 is located on one side of the first bracket 5, and the second bracket 1 is used to fix the workpiece 2 on the side facing the first bracket 5. A plurality of elastic pressure components 4 can be arranged at intervals along the circumference of the first bracket 5, and the elastic pressure components 4 are arranged toward the second bracket 1. The first bracket 5 can drive the workpiece 2 to move toward the second bracket 1, so that the plurality of elastic pressure components 4 can be pressed against the outer periphery of the workpiece 2.

[0041] Of course, regarding the arrangement of the multiple elastic pressure components 4, those skilled in the art may determine it according to actual conditions, and no specific limitation is made here.

[0042] In the specific embodiments of the present application, Figure 3 and Figure 5As shown, a support plate 12 is mounted on the second bracket 1. For example, the support plate 12 can be connected to the second bracket 1 by fixed clamping, welding or screwing. The support plate 12 is suitable for supporting and fixing the workpiece 2. The support plate 12 can be a rectangular ring structure, or can be other shapes to adapt to the shape and structure of the workpiece 2.

[0043] The support plate 12 is provided with a positioning member 121 for positioning the workpiece 2. For example, the workpiece 2 has a hole, and the positioning member 121 may be a positioning column or a positioning pin, which can be inserted into the hole to position the workpiece 2. Alternatively, the positioning member 121 may also be a plurality of positioning blocks, which cooperate with each other to abut against the periphery to be pressed to fix the workpiece 2. Of course, the structure of the positioning member 121 can be determined by those skilled in the art according to actual conditions, and is not specifically limited here.

[0044] In the specific embodiment of the present application, the second bracket 1 and the first bracket 5 can be aluminum alloy brackets with high strength and light weight. Alternatively, the second bracket 1 and the first bracket 5 can also be made of iron or mild steel, etc., which can be determined by those skilled in the art according to actual conditions and are not specifically limited here.

[0045] In an example, Figures 1 to 4 As shown, the clamping device further includes a pressing plate 3 , and the plurality of elastic pressure components 4 are suitable for driving the pressing plate 3 to press tightly against the workpiece 2 .

[0046] The elastic pressure assembly 4 drives the pressing plate 3 to press the workpiece 2, so that the pressing force on the glue pressing structure in various areas of the workpiece 2 can be kept stable and more uniform, thereby improving the pressure-maintaining effect. It can also increase the area of ​​the workpiece 2 that is pressed, thereby preventing the workpiece 2 from being damaged due to excessive force in some areas.

[0047] In a specific embodiment of the present application, one end of the elastic pressure assembly 4 can be connected to the pressing plate 3, and the pressing plate 3 is located on the side of the second bracket 1 where the workpiece 2 is placed, so that the elastic pressure assembly 4 can drive the pressing plate 3 to move toward the second bracket 1, thereby pressing the workpiece.

[0048] In one example, the pressing plate 3 is disposed on the side of the second bracket 1 where the workpiece 2 is placed. The pressing plate 3 can press the workpiece 2, thereby increasing the area of ​​the pressing contact with the workpiece 2 to improve the pressure-maintaining effect and prevent the workpiece 2 from being damaged due to excessive local force.

[0049] like Figure 1As shown, in a specific embodiment of the present application, one side of the second bracket 1 is used to place the workpiece 2, and the pressing plate 3 is located on the side of the second bracket 1 suitable for placing the workpiece 2. The pressing plate 3 is facing the side of the workpiece 2 and can press the workpiece 2 to maintain the pressure of the workpiece 2. Therefore, by providing the pressing plate 3 to press the workpiece 2, the area pressed on the workpiece 2 can be increased to improve the pressure-maintaining effect.

[0050] In a specific embodiment of the present application, the pressing plate 3 may be a steel plate, which has a low strength and can avoid crushing the workpiece 2. Alternatively, the pressing plate 3 may also be made of other plastic or silicone materials, etc., which can be determined by those skilled in the art according to actual conditions and are not specifically limited here.

[0051] In an example, Figure 4 As shown, there are multiple pressing plates 3, each of which is connected to one or more elastic pressure components 4, and the multiple pressing plates 3 are suitable for pressing different parts of the workpiece 2. That is, when the length of the pressing plate 3 is relatively long, multiple elastic pressure components 4 can be connected. For example, one pressing plate can be driven to move by two, three or four elastic pressure components 4. When the length of the pressing plate is relatively short, one elastic pressure component 4 can be connected. There are multiple pressing plates 3, each of which can be used to press different areas of the workpiece 2, so that it can adapt to the structure of different areas of the workpiece 2, so that the pressing force applied to each part of the workpiece 2 remains stable and more uniform, so as to improve the pressing effect.

[0052] like Figure 4 As shown, there are multiple pressing plates 3, and multiple pressing plates 3 are arranged along the circumference of the first bracket 5, or two pressing plates 3 are arranged at intervals along the width direction of the first bracket 5. By setting the pressing plate 3 to press the workpiece 2, the pressing area can be increased. Each pressing plate 3 can correspond to different areas of different workpieces 2, and each pressing plate 3 is driven by an independent elastic pressure component 4, so that each pressing plate 3 can adapt to the glue pressing structure of different areas of the workpiece 2, so that the pressing force on each part of the workpiece 2 remains stable and more uniform, so as to improve the pressing effect.

[0053] In the specific embodiments of the present application, Figure 4 As shown, there are multiple pressing plates 3, each of which is driven by multiple elastic pressure components 4 to press the workpiece 2. The multiple elastic pressure components 4 are spaced along the length direction of the pressing plate 3 to increase the pressing force of the pressing plate 3 to press the workpiece 2. For example, the pressing plate 3 can be driven by two, three, four or five elastic pressure components 4. Those skilled in the art can determine according to actual conditions. For example, the number of elastic pressure components 4 can be set according to the length of the pressing plate 3, and no specific limitation is made here. Alternatively, the pressing plate 3 can also be driven by one elastic pressure component 4 to press the workpiece 2.

[0054] In the specific embodiment of the present application, the side of the pressing plate 3 used for pressing the workpiece 2 is set as a pressing surface. The length and width of the pressing surface can be determined by those skilled in the art according to actual conditions and are not specifically limited here.

[0055] In an example, Figure 4 As shown, the clamping device further includes a first connecting plate 6, which is connected to one side of the pressing plate 3, and the elastic pressure assembly 4 is connected to the pressing plate 3 through the first connecting plate 6. Multiple elastic pressure assemblies 4 can be connected to the pressing plate 3 through the first connecting plate 6, so that the pressure at various locations of the pressing plate 3 can be more uniform, thereby preventing the pressing plate 3 from being partially deformed by compression.

[0056] like Figure 4 As shown, in a specific embodiment of the present application, the size and shape of the first connecting plate 6 correspond to the pressing plate 3. One side of the pressing plate 3 along the thickness direction is set as a clamping surface, and the clamping surface is used to clamp the workpiece 2. The first connecting plate 6 can cover and connect to the side of the pressing plate 3 away from the clamping surface. That is, the first connecting plate 6 is attached to the side of the pressing plate 3 away from the clamping surface. The elastic pressure component 4 is connected to the first connecting plate 6, and the elastic pressure component 4 can apply pressure to the first connecting plate 6, and can be transmitted to the pressing plate 3 through the first connecting plate 6, so that the pressure of each part of the pressing plate 3 is more uniform, avoiding local deformation of the pressing plate 3.

[0057] In a specific embodiment of the present application, the first connecting plate 6 can be connected to the pressing plate 3 by bonding or screwing with studs. One end of the elastic pressure component 4 is connected to the end of the first connecting plate 6 away from the pressing plate 3, and the other end of the elastic pressure is connected to the first bracket 5. The first bracket 5 moves toward the second bracket 1, which can drive the multiple elastic pressure components 4 to apply pressure to the first connecting plate 6, thereby pushing the pressing plate 3 to press the workpiece 2.

[0058] In an example, Figure 6 As shown, the elastic pressure assembly 4 includes an elastic member 42 and a push member 41, wherein the push member 41 is connected to the first bracket 5, and the push member 41 can drive the elastic member 42 to press the workpiece 2. The elastic member 42 is suitable for pressing the workpiece 2. By pressing the workpiece 2 with the elastic member 42, the force on different areas of the workpiece 2 can be made as uniform and stable as possible, so as to improve the pressure-maintaining effect.

[0059] In a specific embodiment of the present application, the elastic pressure assembly 4 further includes a pusher 41, which is fixedly connected to the first bracket 5. The pusher 41 can drive the elastic member 42 to press the workpiece 2. The first bracket 5 can drive the pusher 41 to push the elastic member 42, so that the elastic member 42 presses the workpiece 2.

[0060] In a specific embodiment of the present application, the elastic member 42 can be arranged on the side of the pressing plate 3 away from the second bracket 1, and the pushing member 41 abuts against the side of the elastic member 42 away from the pressing plate 3. That is, the elastic member 42 is located between the pushing member 41 and the pressing plate 3 to position the elastic member 42. The first bracket 5 can drive the pushing member 41 to push the elastic member 42, so that the elastic member 42 elastically pushes the pressing plate 3 to press the workpiece 2.

[0061] In one example, one end of the elastic member 42 abuts against the pushing member 41, and the pushing member 41 can push the other end of the elastic member 42 to press the workpiece 2. For example, the elastic member 42 is a compression spring, one end of the spring abuts against the pushing member 41, and the pushing member 41 can push the spring to compress, so that the other end of the spring can push the pressing plate 3 to press the workpiece 2. Alternatively, the elastic member 42 can also be other elastic structures, such as a torsion spring, etc., which can be determined by those skilled in the art according to actual conditions and is not specifically limited here.

[0062] Among them, Figure 6 As shown, the workpiece 2 further includes a second connecting plate 45, which can be screwed to the pressure plate 3 by means of a stud. One end of the spring abuts against the pusher 41, and the other end abuts against the second connecting plate 45. The pusher 41 can push the spring to compress, so that the other end of the spring can push the second connecting plate 45.

[0063] Alternatively, a first connecting plate 6 may be provided between the second connecting plate 45 and the pressing plate 3. That is, the first connecting plate 6 covers and is connected to the side of the pressing plate 3 away from the pressing surface, and the second connecting plate 45 is screwed to the first connecting plate 6 via a stud. The connection method of the elastic pressure assembly 4 may be determined by those skilled in the art according to actual conditions, and is not specifically limited here.

[0064] In an example, Figure 6 As shown, the elastic pressure assembly 4 further includes a first guide column 43, which is slidably disposed in the pusher 41, and the elastic member 42 is sleeved on the first guide column 43. By sleeve-fitting the elastic member 42 on the first guide column 43, the first guide column 43 can limit the elastic member 42, so that the elastic member 42 can stably push the pressing plate 3 to press the workpiece 2.

[0065] like Figure 6 As shown, in a specific embodiment of the present application, the first guide column 43 is slidably disposed in the pusher 41, the pusher 41 can slide along the first guide column 43, the first guide column 43 can guide the pusher 41, and one end of the pusher 41 abuts against the elastic component 42. The elastic component 42 can be a spring. The elastic component 42 is sleeved on the first guide column 43, and the first guide column 43 can limit the elastic component 42.

[0066] In the specific embodiments of the present application, Figure 6 As shown, one end of the first guide column 43 is connected to the second connecting plate 45. For example, the first guide column 43 and the second connecting plate 45 can be connected by interference fit or threaded connection. The elastic member 42 is sleeved on the first guide column 43, and one end of the elastic member 42 abuts against the pusher 41, and the other end abuts against the second connecting plate 45.

[0067] Among them, one end of the second connecting plate 45 facing away from the elastic member 42 is connected to the first connecting plate 6, and the first connecting plate 6 is connected to the pressing plate 3. The pressure-maintaining process of the clamping device of the present application is to fix the workpiece 2 on the support plate 12, and move the first bracket 5 toward the support plate 12 to drive the pushing member 41 to squeeze one end of the elastic member 42, and the other end of the elastic member 42 can push the second connecting plate 45, thereby pushing the pressing plate 3 to press the workpiece 2 on the support plate 12 to maintain the pressure of the workpiece 2.

[0068] In an example, Figure 6 As shown, there are a plurality of first guide posts 43. The plurality of first guide posts 43 are respectively disposed in the pusher 41, which can improve the stability of the movement of the pusher 41. In addition, an elastic member 42 is sleeved on each first guide post 43 to increase the pressing pressure.

[0069] like Figure 6 As shown, in a specific embodiment of the present application, a plurality of first guide posts 43 are provided, and the plurality of guide posts are respectively slidably penetrated through the pusher 41. An elastic member 42 is sleeved on each first guide post 43, so as to increase the pressure of the elastic pressure assembly 4 on the pressure plate 3. For example, two, three or four guide posts may be provided, and those skilled in the art may determine according to actual conditions, and no specific limitation is made here.

[0070] In one example, the elastic pressure assembly 4 further includes a limiter 44, and the limiters 44 are respectively connected to the plurality of first guide posts 43 to limit the pusher 41 from sliding off the first guide posts 43. The limiters 44 are respectively connected to the plurality of first guide posts 43 to stabilize the plurality of first guide posts 43. The limiters 44 can limit the pusher 41 from sliding off the first guide posts 43 to improve the reliability of the structure.

[0071] In a specific embodiment of the present application, the elastic pressure assembly 4 further includes a stopper 44, which is connected to the first guide column 43 to limit the pusher 41 from sliding off the first guide column 43, so as to improve the reliability of the overall structure of the elastic pressure assembly 4. For example, the stopper 44 may be a bolt, which is screwed to one end of the first guide column 43 away from the second connecting plate 45, and the outer diameter of the bolt head is larger than the inner diameter of the hole on the pusher 41, so as to limit the pusher 41 from sliding off the first guide column 43.

[0072] like Figure 6 As shown, in a specific embodiment of the present application, a plurality of first guide posts 43 are provided, and the position limiting member 44 may also be a position limiting sheet structure. The position limiting sheets can be respectively connected to the ends of the plurality of first guide posts 43. For example, a stud is passed through the position limiting sheet and screwed to the first guide post 43 to fix the position limiting member 44. The position limiting member 44 can improve the reliability of the position limiting of the pusher 41 by providing the position limiting member 44.

[0073] In an example, Figure 6 As shown, the pusher 41 is provided with a protrusion 411 toward the first bracket 5, and the protrusion 411 is connected to the first bracket 5. By providing the protrusion 411 on the pusher 41, sufficient installation space can be provided for the pusher 41 to be connected to the first bracket 5, so as to facilitate the installation operation.

[0074] The first guide column 43 is located at one side of the protrusion 411. A clearance space can be reserved for the first guide column 43, and when the pusher 41 slides along the first guide column 43, the first guide column 43 can be avoided to avoid interference between the first guide column 43 and the first bracket 5.

[0075] like Figure 6 As shown, in a specific embodiment of the present application, a protrusion 411 is provided at one end of the pusher 41 away from the elastic member 42, and the protrusion 411 can be connected to the first bracket 5. For example, a plurality of studs are passed through the protrusion 411 and screwed to the first bracket 5, or the connection can be fixed by riveting or welding. The first guide column 43 passes through the pusher 41 and is located on one side of the protrusion 411. By providing the protrusion 411, when the pusher 41 slides along the first guide column 43, it can avoid the first guide column 43 to avoid interference between the first guide column 43 and the first bracket 5.

[0076] like Figure 6 As shown, multiple protrusions 411 can be provided to improve the stability of the connection to the first bracket 5. For example, two protrusions 411 are provided, and the two protrusions 411 are respectively located on opposite sides of the pusher 41, and an avoidance groove can be formed between the two protrusions 411, and the first guide column 43 is located between the two protrusions 411.

[0077] In a specific embodiment of the present application, the protrusion 411 may be a connection block structure, and the connection block may be connected to the pusher 41 by riveting, screwing or welding. Alternatively, the protrusion 411 may be integrally formed with the pusher 41, that is, the pusher 41 is provided with a protrusion toward the first bracket 5. Of course, the arrangement of the protrusion 411 may be determined by those skilled in the art according to actual conditions, and is not specifically limited here.

[0078] In one example, the clamping device further includes a second bracket 1, the second bracket 1 is suitable for placing the workpiece 2, and the first bracket 5 can move toward or away from the second bracket 1. The first bracket 5 can move toward the second bracket 1 to drive the elastic pressure component 4 to press the workpiece 2 to maintain pressure on the workpiece 2. After the pressure maintenance is completed, the first bracket 5 moves away from the second bracket 1 to facilitate the removal of the workpiece 2 from the second bracket 1.

[0079] In an example, Figures 3 to 5 As shown, the first bracket 5 is movably connected to the second bracket 1 , the second bracket 1 is provided with a second guide column 11 , the first bracket 5 is provided with a guide hole 51 , and the second guide column 11 is inserted into the guide hole 51 .

[0080] like Figures 3 to 5 As shown, in a specific embodiment of the present application, the second bracket 1 is provided with a second guide column 11, and the first bracket 5 is provided with a guide hole 51. The second guide column 11 is inserted into the guide hole 51, and the first bracket 5 can move along the second guide column 11. By providing the second guide column 11, the stability and smoothness of the movement of the first bracket 5 can be improved, so that the first bracket 5 can drive the multiple elastic pressure components 4 to press the workpiece 2.

[0081] In one example, the second guide column 11 is screwed with a fastener 7, and the first bracket 5 can be driven to move toward the second bracket 1 through the fastener 7. The fastener 7 is screwed to the second guide column 11, and the first bracket 5 can be driven to move toward the second bracket 1 by rotating the fastener 7, so as to control the moving distance of the first bracket 5, thereby facilitating the adjustment of the pressure of the elastic pressure component 4 on the workpiece 2 to improve the pressure holding effect.

[0082] For example, the fastener 7 is screwed to the second guide column 11 and is located on the side of the first bracket 5 away from the second bracket 1. By screwing the fastener 7 forward, the fastener 7 can move toward the second bracket 1, thereby pushing the first bracket 5 to move toward the second bracket 1, so as to push the elastic pressure component 4 to press the workpiece 2 for pressure maintenance. When the pressure maintenance is completed, the fastener 7 is screwed out in the reverse direction, and the first bracket 5 can move in a direction away from the second bracket 1 under the push of the elastic pressure component 4, so as to facilitate the removal of the workpiece 2.

[0083] In a specific embodiment of the present application, the fastener 7 can be automatically rotated by an automated device such as a manipulator to improve the accuracy of the pressure applied to the workpiece 2. In addition, the screwing distance of the fastener 7 can be adjusted according to the pressure holding requirements of different workpieces 2 to apply a reasonable pressure holding force to the workpiece 2.

[0084] like Figure 5As shown, in a specific embodiment of the present application, a plurality of second guide posts 11 are provided, and the plurality of second guide posts 11 are arranged at intervals along the circumference of the second bracket 1, and the second bracket 1 is correspondingly provided with a plurality of guide holes 51. By providing a plurality of second guide posts 11, the stability of the connection between the first bracket 5 and the second bracket 1 can be improved.

[0085] Of course, the second guide column 11 can also be arranged on the first bracket 5, and the second bracket 1 is correspondingly provided with a guide hole 51. Those skilled in the art can determine according to actual conditions, and no specific limitation is made here.

[0086] like Figure 5 As shown, in a specific embodiment of the present application, the second guide column 11 has a stopper and a threaded portion.
