Description

Technical Field

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

[0002] Before milling a workpiece, it is necessary to clamp and position it. In related technologies, one workpiece is usually clamped at a time, which results in low clamping efficiency. Utility Model Content

[0003] One embodiment of this application provides a clamping device capable of simultaneously clamping two or more workpieces.

[0004] This application provides a clamping device, including a base, a clamping assembly, and a driving assembly. The base has two or more limiting grooves, each of which is configured to accommodate a workpiece. The clamping assembly includes two or more clamping members, each of which is movably disposed on the base and corresponds to a limiting groove. The driving assembly includes a power member and a pusher member, the power member being connected to the pusher member and configured to drive the pusher member to move relative to the base. The pusher member has two or more inclined surfaces spaced apart along its moving direction, the inclined surfaces being inclined relative to the moving direction, each inclined surface being configured to abut against a clamping member, and when the pusher member moves, it pushes the clamping member toward the corresponding limiting groove to clamp the workpiece in the limiting groove.

[0005] In the aforementioned clamping device, each workpiece is inserted into its corresponding limiting groove from top to bottom. A power component drives a pusher to move, which in turn moves multiple clamping members simultaneously via an inclined plane. Each clamping member holds a workpiece within a limiting groove, allowing the clamping assembly to simultaneously clamp multiple workpieces. Each clamping member and the inner wall of its corresponding limiting groove jointly clamp a workpiece, enabling the clamping device to quickly clamp and position multiple workpieces, thus improving clamping efficiency. The base confines the workpiece within the limiting groove, which pre-positions the workpiece, preventing it from shifting relative to the clamping members and ensuring accurate workpiece clamping.

[0006] In some embodiments, inclined surfaces are respectively disposed on both sides of the pusher along the moving direction.

[0007] The clamps are arranged in two rows on both sides of the pusher, allowing the pusher to move both rows of clamps simultaneously, and also separating the two rows of clamps to prevent interference between the clamps on both sides of the pusher during movement. In some embodiments, each clamp includes an elastic element and a chuck, the elastic element connecting the base and the chuck, and is configured to elastically deform when pushed by a corresponding inclined surface during the movement of the pusher.

[0008] In some embodiments, each clamp includes an elastic element and a clamp, the elastic element connecting the base and the clamp and being configured to be elastically deformed by being pushed against by the corresponding clamp as the pusher moves.

[0009] When the clamp holds the workpiece, the elastic element buffers the impact force through its own elastic compression, preventing the clamp from crushing the workpiece and protecting it from damage. When the inclined plane moves away from the clamp, the elastic element rebounds, causing the clamp to return to its original position against the inclined plane, maintaining the connection between the inclined plane and the clamp.

[0010] In some embodiments, each clamp is provided with a receiving groove for receiving an elastic member, and the base is provided with a protrusion extending into the receiving groove and configured to abut against the inner wall of the receiving groove.

[0011] When the clamp moves relative to the base, the protrusion moves relative to the receiving groove along the direction of movement of the clamp, which can resist the elastic deformation of the elastic element. The receiving groove positions the installation position of the elastic element to prevent misalignment of the elastic element during elastic deformation.

[0012] In some embodiments, each limiting groove has an inner wall with an opening facing the chuck, and each chuck is configured to enter the limiting groove through the opening and engage with the inner wall to clamp the workpiece when pushed against the inclined plane.

[0013] By setting an opening to avoid the chuck, the chuck can enter the limiting groove through the opening and push the workpiece to the area on the inner wall where there is no opening, so that the chuck and the inner wall together clamp the workpiece.

[0014] In some embodiments, the inner wall of the limiting groove includes an adjacent first clamping wall and a second clamping wall, the normal direction of the first clamping wall is parallel to the moving direction of the pusher, and the normal direction of the second clamping wall is perpendicular to the moving direction of the pusher; both the first clamping wall and the second clamping wall are configured to cooperate with the chuck to clamp the workpiece.

[0015] The first clamping wall is perpendicular to the second clamping wall. When the chuck moves under the push of the inclined plane, the workpiece can move close to the first clamping wall and the second clamping wall at the same time under the push of the chuck, so that the chuck, the first clamping wall and the second clamping wall can clamp the workpiece together.

[0016] In some embodiments, the chuck includes a first surface and a second surface, the first surface and the first clamping wall being spaced apart along the moving direction of the pusher, and the second surface and the second clamping wall being spaced apart along the direction perpendicular to the moving direction. Both the first surface and the second surface are configured to abut against the workpiece and push the workpiece against the first clamping wall and the second clamping wall.

[0017] When the clamp moves relative to the base, the first and second surfaces together push the workpiece against the first and second clamping walls, so that the first surface and the first clamping wall, the second surface and the second clamping wall clamp the workpiece in two mutually perpendicular directions, so as to clamp and position the workpiece.

[0018] In some embodiments, the chuck includes an arcuate surface configured to abut against a workpiece and push the workpiece against a first clamping wall and a second clamping wall.

[0019] When the clamp moves relative to the base, the arc-shaped surface pushes the workpiece against the first clamping wall and the second clamping wall, so that the arc-shaped surface, the first clamping wall and the second clamping wall together clamp the workpiece. When the workpiece is cylindrical, the arc-shaped surface can naturally fit with the side surface of the workpiece. Under the pushing of the arc-shaped surface, the workpiece is not easy to shift relative to the arc-shaped surface, so that the workpiece can move smoothly with the chuck.

[0020] In some embodiments, the base is provided with a first guide groove that extends along the moving direction of the pusher and is configured to slidably connect to the pusher to guide its movement.

[0021] The pusher is guided to move by the first guide groove to prevent it from deviating during the movement.

[0022] In some embodiments, the base is provided with a second guide groove that extends along a first direction and is configured to slide and connect a clamp to guide the clamp to move. The first direction is parallel to the normal direction of the inclined plane.

[0023] The clamping component is guided to move by a second guide groove to prevent it from deviating during the movement. Attached Figure Description

[0033] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation

[0034] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0037] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0039] Before milling a workpiece, it is necessary to clamp and position it. In related technologies, one workpiece is usually clamped at a time, which results in low clamping efficiency.

[0040] This application provides a clamping device, including a base, a clamping assembly, and a driving assembly. The base has two or more limiting grooves, each of which is configured to accommodate a workpiece. The clamping assembly includes two or more clamping members, each of which is movably disposed on the base and corresponds to a limiting groove. The driving assembly includes a power member and a pusher member, the power member being connected to the pusher member and configured to drive the pusher member to move relative to the base. The pusher member has two or more inclined surfaces spaced apart along its moving direction, the inclined surfaces being inclined relative to the moving direction, each inclined surface being configured to abut against a clamping member, and when the pusher member moves, it pushes the clamping member toward the corresponding limiting groove to clamp the workpiece in the limiting groove.

[0041] In the aforementioned clamping device, each workpiece is inserted into its corresponding limiting groove from top to bottom. A power component drives a pusher to move, which in turn moves multiple clamping members simultaneously via an inclined plane. Each clamping member holds a workpiece within a limiting groove, allowing the clamping assembly to simultaneously clamp multiple workpieces. Each clamping member and the inner wall of its corresponding limiting groove jointly clamp a workpiece, enabling the clamping device to quickly clamp and position multiple workpieces, thus improving clamping efficiency. The base confines the workpiece within the limiting groove, which pre-positions the workpiece, preventing it from shifting relative to the clamping members and ensuring accurate workpiece clamping.

[0042] The embodiments of this application will be further described below with reference to the accompanying drawings. Unless otherwise specified, the various embodiments in this application can be combined with each other.

[0043] Please see Figures 1 to 3 This application provides a clamping device 100, including a base 10, a clamping assembly 20, and a driving assembly 30. The clamping assembly 20 is movably disposed on the base 10, and the driving assembly 30 is connected to the clamping assembly 20 and configured to drive the clamping assembly 20 to move relative to the base 10.

[0044] Please see Figure 1 and Figure 2In some embodiments, the base 10 has one or more limiting grooves 101, each limiting groove 101 configured to accommodate one workpiece 200. The clamping assembly 20 includes one or more clamping members 21, each clamping member 21 corresponding to one limiting groove 101. The clamping assembly 20 is driven to move by the driving assembly 30, so that each clamping member 21 can push against the workpiece 200 in the corresponding limiting groove 101 and move, and together with the inner wall of the corresponding limiting groove 101, clamp a workpiece 200, thereby enabling the clamping assembly 20 to clamp multiple workpieces 200 simultaneously. In this way, the clamping device 100 can quickly clamp and position multiple workpieces 200, improving the positioning efficiency of the workpieces 200.

[0045] The base 10 can restrict the workpiece 200 within the limiting groove 101. The limiting groove 101 pre-positions the workpiece 200, preventing the workpiece 200 from shifting relative to the clamp 21, so that the clamp 21 can accurately clamp the workpiece 200.

[0046] In some embodiments, the base 10 is provided with two rows of limiting grooves 101, which are spaced apart along the width direction Y of the base 10. Each row of limiting grooves 101 includes one or more limiting grooves 101 spaced apart along the length direction X of the base 10. For ease of description, the width direction Y of the base 10 is referred to as the width direction Y, and the length direction X of the base 10 is referred to as the length direction X.

[0047] Please see Figure 3 The drive assembly 30 is disposed between two rows of limiting slots 101. A row of clamping members 21 is provided between the drive assembly 30 and each row of limiting slots 101. Each row of clamping members 21 includes one or more clamping members 21 spaced apart along the length direction X, and each clamping member 21 corresponds to one limiting slot 101. The more limiting slots 101 and clamping members 21 there are, the more workpieces 200 can be locked simultaneously by the clamping assembly 20. In the illustrated embodiment, each row of limiting slots 101 includes three limiting slots 101 spaced apart along the length direction X. The six clamping members 21 are distributed in two rows on both sides of the drive assembly 30, so that the drive assembly 30 can drive the two rows of clamping members 21 to move simultaneously.

[0048] Please see Figure 4 In some embodiments, the base 10 includes a base plate 11 and a cover plate 12, with the cover plate 12 stacked on the base plate 11. The clamping assembly 20 and part of the driving assembly 30 are disposed between the base plate 11 and the cover plate 12 to protect the clamping assembly 20 and part of the driving assembly 30.

[0049] Please see Figure 4 and Figure 5In some embodiments, the drive assembly 30 includes a power member 31 and a pusher 32. The power member 31 is fixed to the base plate 11, and the pusher 32 is movably disposed on the base plate 11. The power member 31 is connected to the pusher 32 and configured to drive the pusher 32 to move relative to the base 10. The pusher 32 has one or more inclined surfaces 321 along its direction of movement, with the inclined surfaces 321 inclined relative to the direction of movement. Each inclined surface 321 is configured to abut against a clamping member 21, and each inclined surface 321 pushes a clamping member 21 toward a corresponding limiting groove 101, so that the clamping member 21 clamps the workpiece 200 in the limiting groove 101. The direction of movement of the pusher 32 is parallel to the length direction X. For ease of description, the direction of movement of the pusher 32 is referred to as the movement direction.

[0050] When the pusher 32 is provided with two or more inclined surfaces 321, with the moving direction (length direction X) as the central axis, the two or more inclined surfaces 321 are respectively provided on both sides of the pusher 32 along the moving direction (length direction X).

[0051] The inclined surfaces 321 are arranged in two rows on both sides of the pusher 32, which can simultaneously push the two rows of clamps 21 distributed on both sides of the drive assembly 30 to move. The pusher 32 can separate the two rows of clamps 21 to prevent the two rows of clamps 21 from interfering when moving.

[0052] The power component 31 drives the pusher 32 to move back and forth, so that the pusher 32 drives multiple clamping parts 21 to move towards the limiting groove 101 or away from the limiting groove 101 simultaneously via the inclined surface 321. This is convenient to operate and makes it easy for the clamping assembly 20 to simultaneously lock or release multiple workpieces 200.

[0053] In some embodiments, the power component 31 is a linear drive structure, which includes a piston cylinder or a slide cylinder; this application does not impose any limitations on this. Please refer to [link / reference]. Figure 5 and Figure 6 In some embodiments, the base 10 is provided with a first guide groove 112 and a second guide groove 121. The first guide groove 112 extends along the moving direction (length direction X) and is configured to connect to the pusher 32 to guide the pusher 32 to move and prevent the pusher 32 from deviating from the length direction X during movement. The second guide groove 121 extends along a first direction A and is configured to slide to connect to the clamp 21 to guide the clamp 21 to move and prevent the clamp 21 from deviating from the first direction A during movement.

[0054] Please see Figure 4 and Figure 6In some embodiments, the first direction A is parallel to the normal direction of the inclined plane 321, and the first direction A forms an angle α with the length direction X. When the inclined plane 321 moves against the clamp 21, the clamp 21 moves a distance relative to both the length direction X and the width direction Y, so that the clamp 21 can clamp the workpiece 200 in both the length direction X and the width direction Y.

[0055] In some embodiments, the angle α formed by the first direction A and the length direction X is 45°, so that when the clamp 21 pushes the workpiece 200 to move along the first direction A, the workpiece 200 moves the same distance in the length direction X and the width direction Y. Furthermore, depending on the shape of the workpiece 200, the angle α can also be other angles.

[0056] Please see Figure 5 and Figure 6 In some embodiments, the first guide groove 112 is located on the side of the base plate 11 facing the cover plate 12, and the second guide groove 121 is located on the side of the cover plate 12 facing the base plate 11. During assembly, the pusher 32 is installed in the first guide groove 112, the clamping member 21 is installed in the second guide groove 121, and the cover plate 12 is closed onto the base plate 11 to complete the assembly, which is simple. By separating the first guide groove 112 and the second guide groove 121, the risk of deformation occurs when a single plate (such as the base plate 11) simultaneously guides two moving parts, and the overall rigidity and operational stability of the clamping device 100 are improved.

[0057] Please see Figure 3 In some embodiments, each clamp 21 includes an elastic element 212 and a chuck 211. The two ends of the elastic element 212 are connected to the base 10 and the chuck 211, respectively, and are configured to elastically deform when pushed by the corresponding chuck 211 as the pusher 32 moves. One end of the chuck 211 abuts against the inclined surface 321, and the other end of the chuck 211 is used to clamp the workpiece 200. Exemplarily, the side of the chuck 211 that abuts against the inclined surface 321 is an arc surface.

[0058] When the clamp 21 holds the workpiece 200, the inclined surface 321 pushes the chuck 211 to move toward the limiting groove 101, and the elastic element 212 is elastically compressed. The elastic element 212 buffers the impact force through its own elastic compression, preventing the chuck 211 from crushing the workpiece 200, thus protecting the workpiece 200 and reducing the risk of the workpiece 200 being crushed or pinched.

[0059] When the inclined plane 321 moves away from the clamp 21, the elastic element 212 rebounds and causes the chuck 211 to return to its original position against the inclined plane 321, so that the chuck 211 remains connected to the inclined plane 321 and the chuck 211 releases the workpiece 200.

[0060] Please combine Figure 3 and Figure 4In some embodiments, each limiting groove 101 has an inner wall with an opening 1013 facing the chuck 211. Each chuck 211 is configured to enter the limiting groove 101 through the opening 1013 and cooperate with the inner wall to clamp the workpiece 200 when the inclined surface 321 pushes against it.

[0061] By setting an opening 1013 to avoid the chuck 211, the chuck 211 can enter the limiting groove 101 through the opening 1013 and push the workpiece 200 to the area on the inner wall where there is no opening 1013, so that the chuck 211 and the inner wall jointly clamp the workpiece 200.

[0062] Please see Figure 3 and Figure 7 In some embodiments, the inner wall of the limiting groove 101 includes adjacent first clamping walls 1011 and second clamping walls 1012. The normal direction of the first clamping wall 1011 is parallel to the moving direction (length direction X), and the normal direction of the second clamping wall 1012 is perpendicular to the moving direction (length direction X), making the second clamping wall 1012 perpendicular to the first clamping wall 1011. Both the first clamping wall 1011 and the second clamping wall 1012 are configured to cooperate with the chuck 211 to clamp the workpiece 200. When the clamp 21 moves relative to the base 10, the chuck 211 can enter the limiting groove 101 from the opening 1013 and push the workpiece 200 while moving close to the first clamping wall 1011 and the second clamping wall 1012, so that the chuck 211, the first clamping wall 1011 and the second clamping wall 1012 jointly clamp the workpiece 200.

[0063] Please see Figure 6 and Figure 7 The chuck 211 includes a first surface 2111 and a second surface 2112. The first surface 2111 and the first clamping wall 1011 are spaced apart along the moving direction (length direction X), and the second surface 2112 and the second clamping wall 1012 are spaced apart along the direction perpendicular to the moving direction (width direction Y). Both the first surface 2111 and the second surface 2112 are configured to abut against the workpiece 200 and push the workpiece 200 against the first clamping wall 1011 and the second clamping wall 1012.

[0064] When the clamp 21 moves relative to the base 10, the first surface 2111 and the second surface 2112 together push the workpiece 200 against the first clamping wall 1011 and the second clamping wall 1012, so that the first surface 2111 and the first clamping wall 1011 clamp the workpiece 200 along the length direction X, and the second surface 2112 and the second clamping wall 1012 clamp the workpiece 200 along the width direction Y, so as to clamp and position the workpiece 200 from two directions. This is suitable for workpieces 200 of various shapes, such as workpieces 200 with a flat or curved side surface 2113.

[0065] When the workpiece 200 is a square part, the side surface of the workpiece 200 is a plane. The first surface 2111, the second surface 2112, the first clamping wall 1011 and the second clamping wall 1012 can all naturally fit with the side surface of the workpiece 200, so that the workpiece 200 can move smoothly with the chuck 211 under the pushing of the first surface 2111 and the second surface 2112. When the first surface 2111, the second surface 2112, the first clamping wall 1011 and the second clamping wall 1012 clamp the workpiece 200, the side surface of the workpiece 200 is subjected to uniform force, so that the workpiece 200 is not easily damaged or locally deformed, and the side surface of the workpiece 200 can be protected.

[0066] Please see Figure 8 In some embodiments, the chuck 211 includes an arcuate surface 2113; the arcuate surface 2113 is configured to abut against the workpiece 200 and push the workpiece 200 against the first clamping wall 1011 and the second clamping wall 1012.

[0067] When the clamp 21 moves relative to the base 10, the arc-shaped surface 2113 pushes the workpiece 200 against the first clamping wall 1011 and the second clamping wall 1012, so that the arc-shaped surface 2113, the first clamping wall 1011 and the second clamping wall 1012 jointly clamp the workpiece 200.

[0068] When the workpiece 200 is cylindrical, the side surface of the workpiece 200 is an arc surface 2113. The arc surface 2113 can naturally fit with the side surface of the workpiece 200. Under the push of the arc surface 2113, the workpiece 200 is not easy to shift relative to the arc surface 2113, so that the workpiece 200 can move smoothly with the chuck 211.

[0069] Please see Figure 5 , Figure 7 and Figure 8 In some embodiments, the chuck 211 has a receiving groove 2114, and the base 10 has a protrusion 111 extending into the receiving groove 2114. In the illustrated embodiment, the two ends of the protrusion 111 are connected to the base plate 11 and the cover plate 12, respectively. The receiving groove 2114 is configured to receive the elastic member 212, and the protrusion 111 abuts against the elastic member 212 to the inner wall of the receiving groove 2114.

[0070] When the clamp 21 moves relative to the base 10, the protrusion 111 moves relative to the receiving groove 2114, which can push the elastic member 212 to elastically deform. The receiving groove 2114 positions the installation position of the elastic member 212 to prevent the elastic member 212 from being misaligned during elastic deformation.

[0071] When using the above-mentioned clamping device to clamp the workpiece 200, multiple workpieces 200 are each inserted into a limiting groove 101. The pusher 32 is moved along the length direction X by the power component 31. The pusher 32 pushes multiple clamping components 21 to move simultaneously, so that each chuck 211 can be inserted into the corresponding limiting groove 101 from the opening 1013 and pushes the workpiece 200 in the limiting groove 101, so that the workpiece 200 abuts against the first clamping wall 1011 and the second clamping wall 1012. At this time, the chuck 211, the first clamping wall 1011 and the second clamping wall 1012 jointly clamp the workpiece 200, and the workpiece 200 can be processed.

[0072] After the workpiece 200 is processed, the pusher 32 is moved back to its original position along the length direction X by the power component 31. The multiple elastic components 212 rebound and move the multiple chucks 211 toward the pusher 32 until they abut against the inclined surface 321. The chucks 211 release the workpiece 200, and the workpiece 200 can be unloaded.

[0073] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
