[0040] The following combination Figure 1 、 Figure 2 and Figure 3 The clamping device 100 provided in the present application is described.

[0041] The clamping device 100 provided in the present application includes a base 10 , a plurality of top supporting members 20 and a slider 30 .

[0042] The plurality of supporting members 20 are movably disposed on the base 10 , and one of the supporting members 20 can move away from another of the supporting members 20 so that the supporting members 20 support the inner contour of the workpiece 80 .

[0043] like Figure 3 As shown, the workpiece 80 is a hollow structure, that is, the workpiece 80 has its inner contour and its outer contour, and multiple support members 20 are all arranged on the side of the base 10 facing the z direction in the figure. The support members 20 are movable relative to the base 10 in a direction orthogonal to the z direction. The multiple support members 20 can move toward each other or move away from each other. When the multiple support members 20 move away from each other, the contour of the combination of the multiple support members 20 projected in the z direction in the figure increases until at least part of the support members 20 abuts against the inner contour of the workpiece 80. The multiple support members 20 support the inner contour of the workpiece 80 to achieve the fixation of the workpiece 80 on the base 10, so as to facilitate the processing of the outer contour of the workpiece 80.

[0044] The slider 30 is provided on the base 10 and is located between two top supporting members 20 arranged at intervals along the set direction. The distance between the two top supporting members 20 arranged at intervals along the set direction gradually decreases along the first direction, and / or the size of the slider 30 in the set direction gradually increases along the first direction. The slider 30 can move along the first direction to push the top supporting members 20, and the first direction is orthogonal to the set direction.

[0045] As shown in the figure, the first direction is the z direction shown in the figure, the set direction is any direction orthogonal to the first direction z, the set direction includes the x direction in the figure and the y direction in the figure, and the slider 30 can move relative to the base 10 along the x direction in the figure or the y direction in the figure.

[0046] like Figure 3 As shown, the slider 30 is located along Figure 3 Between the two top supporting members 20 arranged in the middle x direction, the distance between the two top supporting members 20 arranged opposite to each other along the x direction in the figure gradually decreases along the first direction z, that is, the gap between the two top supporting members 20 arranged opposite to each other along the x direction in the figure gradually decreases along the first direction z.

[0047] The size of the slider 30 in the setting direction is Figure 3 The distance between one end of the slider 30 in the x direction and the other end of the slider 30 in the x direction, the size of the slider 30 in the set direction gradually increases along the first direction z, that is, the slider 30 gradually becomes thicker along the first direction z.

[0048] In some embodiments, the distance between the two top supporting members 20 spaced apart along the set direction gradually decreases along the first direction z, and the size of the slider 30 in the set direction gradually increases along the first direction z.

[0049] When the slider 30 moves along the first direction z, the slider 30 moves along the Figure 3 The size of the gap between the two supporting members 20 arranged opposite to each other in the x direction gradually increases, and the gap is gradually enlarged along the x direction. Figure 3 The gap between the two supporting members 20 arranged opposite to each other in the x direction gradually decreases so that the slider 30 moves along the Figure 3 The two walls in the x direction are respectively connected to the Figure 3 The two top supporting members 20 arranged opposite to each other in the x direction are against each other and aligned along the Figure 3 The two top supporting members 20 arranged opposite to each other in the x direction generate Figure 3 The thrust in the x direction drives the Figure 3 The two top supporting members 20 arranged opposite to each other in the x direction are away from each other.

[0050] In other embodiments, the distance between the two supporting members 20 arranged at intervals along the set direction gradually decreases along the first direction z, and the size of the slider 30 in the set direction remains unchanged along the first direction z. Figure 3 The gap between the two supporting members 20 arranged opposite to each other in the x direction gradually decreases so that the slider 30 moves along the Figure 3 The end portion in the middle direction presses against the end portion of the top support member 20 toward the slider 30 and pushes the slider along the Figure 3 The two top supporting members 20 arranged opposite to each other in the x direction are away from each other.

[0051] In other embodiments, only the size of the slider 30 in the setting direction gradually increases along the first direction z, and the distance between the two supporting members 20 arranged at intervals along the setting direction remains unchanged along the first direction z. Figure 3 The end portion in the x direction presses against the end portion of the top support member 20 toward the slider 30 and pushes the slider along the Figure 3 The two top supporting members 20 arranged opposite to each other in the x direction are away from each other.

[0052] The beneficial effect of the clamping device 100 provided in the present application is that: the clamping device 100 provided in the present application drives multiple support members 20 to move away from each other through the slider 30 to support the inner contour of the workpiece 80, and the clamping and positioning of the workpiece 80 can be achieved only by being connected to the inner contour of the workpiece 80. When the clamping device 100 provided in the present application clamps the workpiece 80 of the hollow profile, the multiple support members 20 do not block the outer contour of the workpiece 80 and the end of the workpiece 80, so that the processing equipment can process the outer contour of the workpiece 80, including processing the end face and side face of the workpiece 80, so that the clamping device 100 provided in the present application does not affect the processing of the side face and end face of the workpiece 80 while clamping the workpiece 80, and has the advantage of having less impact on the processing efficiency of the workpiece 80.

[0053] In addition, a slider 30 can be used to drive multiple top supporting members 20 to move away from each other, which on the one hand simplifies the driving structure of the multiple top supporting members 20, and on the other hand improves the consistency of the driving of the multiple top supporting members 20. The multiple top supporting members 20 can stably fix the workpiece 80, reducing the risk of the workpiece 80 tilting.

[0054] In some embodiments provided herein, a first inclined surface 21 is provided at the end of the top support member 20 facing the slider 30 , and the angle between the first inclined surface 21 and the set direction is less than 90°. A second inclined surface 31 is provided at the end of the slider 30 facing the top support member 20 and is parallel to the first inclined surface 21 .

[0055] The second inclined surface 31 can abut against the first inclined surface 21 , and the second inclined surface 31 can slide relative to the first inclined surface 21 along the first direction z with the slider 30 to drive the top supporting member 20 to move in a direction away from the slider 30 .

[0056] As shown in FIG3 , the first inclined surface 21 is provided at the end of the top support member 20 facing the slider 30 . The first inclined surfaces 21 of the two top support members 20 arranged at intervals along a set direction are symmetrically arranged about the z-direction. An angle is formed between the first inclined surface 21 and the set direction so that the gap between the two top support members 20 arranged at intervals along the set direction gradually decreases in the direction toward the base 10 .

[0057] The second inclined surface 31 is provided on the side of the slider 30 facing the top support member 20, and multiple second inclined surfaces 31 are provided on the slider 30 so that the multiple second inclined surfaces 31 on the slider 30 are arranged corresponding to the multiple first inclined surfaces 21 on the top support members 20. The second inclined surfaces 31 and the corresponding first inclined surfaces 21 on the top support members 20 are arranged in parallel so that the profile of the slider 30 in the first direction z gradually increases along the z direction toward the base 10.

[0058] The first inclined surface 21 and the second inclined surface 31 are parallel to each other. When the slider 30 moves along the first direction z, the second inclined surface 31 moves along the first direction z until the second inclined surface 31 and the first inclined surface 21 abut against each other. After the second inclined surface 31 abuts against the first inclined surface 21, when the second inclined surface 31 continues to move along the first direction z, the second inclined surface 31 and the first inclined surface 21 rub against each other and the second inclined surface 31 slides relative to the first inclined surface 21 along the extension direction of the first inclined surface 21 or the second inclined surface 31, so that the second inclined surface 31 has a motion component in the set direction, so as to drive the top support member 20 to move along the set direction orthogonal to the first direction z, thereby converting the motion of the slider 30 along the first direction z into the motion of the top support member 20 orthogonal to the first direction z through the relative sliding of the first inclined surface 21 and the second inclined surface 31.

[0059] Thus, when the slider 30 moves along the first direction z, the slider 30 moves along the Figure 3The size of the gap between the two supporting members 20 arranged opposite to each other in the x direction gradually increases, and the gap is gradually enlarged along the x direction. Figure 3 The gap between the two supporting members 20 arranged opposite to each other in the x direction gradually decreases so that the slider 30 moves along the Figure 3 The two walls in the x direction are respectively connected to the Figure 3 The two top supporting members 20 arranged opposite to each other in the x direction are against each other and aligned along the Figure 3 The two top supporting members 20 arranged opposite to each other in the x direction generate Figure 3 The thrust in the x direction drives the Figure 3 The two top supporting members 20 arranged opposite to each other in the x direction are away from each other.

[0060] In some embodiments provided in the present application, a plurality of top support members 20 include a first member, a second member, a third member and a fourth member, the first member and the second member are arranged at intervals along the second direction, the slider 30 is located between the first member and the second member, the third member and the fourth member are arranged at intervals along a third direction orthogonal to the second direction, and the slider 30 is located between the third member and the fourth member.

[0061] like Figure 1 and Figure 2 As shown, the setting direction includes a second direction x and a third direction y, the second direction x and the third direction y are orthogonal, and the first piece, the third piece, the second piece and the fourth piece are evenly spaced along the outer peripheral side of the slider 30, so that the first piece and the second piece are spaced apart along the second direction x and symmetrically arranged about the third direction y, and the third piece and the fourth piece are spaced apart along the third direction y and symmetrically arranged about the second direction x.

[0062] Thus, by moving the slider 30 along the first direction z, the first and second parts can be driven to move away from each other while the third and fourth parts can be driven to move away from each other, so that the first, second, third and fourth parts are all supported on the inner contour of the workpiece 80, thereby preventing the workpiece 80 from moving along the second direction x or the third direction y, and limiting the translational freedom of the workpiece 80 along the second direction x and the third direction y.

[0063] In some embodiments, the inner contour of the workpiece 80 includes four edges, and the first piece, the second piece, the third piece and the fourth piece can respectively correspond to the four edges of the inner contour of the workpiece 80, thereby fixing the workpiece 80 and preventing the workpiece 80 from rotating circumferentially along the slider 30, thereby limiting the rotational freedom of the workpiece 80 along the circumferential direction of the slider 30.

[0064] In some embodiments provided in the present application, an elastic member 23 is provided between the supporting member 20 and the base 10 , and the elastic member 23 is adapted to be compressed when the supporting member 20 supports the inner contour of the workpiece 80 .

[0065] like Figure 3As shown, a guide groove 22 is provided on the side of the support member 20 facing the base 10, and a guide block 111 is provided on the side of the base 10 facing the support member 20. The guide groove 22 extends along a set direction, and the guide block 111 can be slidably assembled in the guide groove 22 to guide the support member 20 when it moves along the set direction.

[0066] An elastic member 23 is provided on the side of the guide block 111 facing away from the slider 30, one end of the elastic member 23 is connected to the end of the guide block 111 facing away from the slider 30, and the other end of the elastic member 23 is connected to the inner wall of the guide groove 22 away from the slider 30, so that the elastic member 23 is compressed when the support member 20 moves along the set direction and supports the inner contour of the workpiece 80, so that the support member 20 is reset through the elastic member 23 when the slider 30 moves in the opposite direction of the first direction z.

[0067] Thus, the slider 30 drives the multiple supporting members 20 to move away from each other so as to support the multiple supporting members 20 against the inner contour of the workpiece 80, and the elastic member 23 drives the multiple supporting members 20 to move closer to each other so that the multiple supporting members 20 are detached from the inner contour of the workpiece 80.

[0068] In some embodiments provided in the present application, the base 10 includes a bottom plate 11, the top support member 20 and the slider 30 are arranged on one side of the bottom plate 11, and the clamping device 100 also includes a top support driving member 60, the top support driving member 60 is fixedly arranged on the other side of the bottom plate 11, and the driving end of the top support driving member 60 passes through the bottom plate 11 and is connected to the slider 30 to drive the slider 30 to slide in a direction perpendicular to the set direction.

[0069] like Figure 3 As shown, the base plate 11 extends perpendicularly to the first direction z, the top support driving member 60 and the slider 30 are respectively arranged on both sides of the base plate 11 along the first direction z, and the guide block 111 is arranged on the side of the base plate 11 facing the top support member 20. The top support driving member 60 can drive the slider 30 to move along the first direction z. The top support driving member 60 can be a linear driving element such as a cylinder or a hydraulic cylinder.

[0070] As a result, the top support driving member 60 and the top support member 20 are respectively located on both sides of the base plate 11 along the first direction z. When the top support driving member 60 drives the slider 30 to move toward the base plate 11, the top support driving member 60 and the slider 30 are subjected to the force in the direction of the slider 30 away from the base plate 11, that is, the direction of the force of the top support driving member 60 on the base plate 11 is the direction of the base plate 11 toward the slider 30, and the top support member 20 is subjected to the force toward the base plate 11, that is, the direction of the force of the top support member 20 on the base plate 11 is the direction of the slider 30 toward the base plate 11, so that the force of the top support member 20 on the base plate 11 and the force of the top support driving member 60 on the base plate 11 offset each other, thereby reducing the deformation of the base plate 11 caused by the force, and improving the positioning accuracy of the clamping device 100 provided in this application.

[0071] In some embodiments provided in the present application, a positioning pad 12 is further provided on the side of the base plate 11 facing the top support member 20. The positioning pad 12 is provided on the outside of multiple top support members 20, and the end of the workpiece 80 facing the base 10 rests against the positioning pad 12 for positioning.

[0072] like Figure 3 As shown, the positioning pad 12 is arranged on the side of the base plate 11 facing the support member 20 and the slider 30, that is, the positioning pad 12 is located on the side of the base plate 11 facing the workpiece 80, and the positioning pad 12 is arranged along the outer peripheral side of multiple support members 20. Therefore, when the workpiece 80 is sleeved on the outer peripheral side of multiple support members 20, the positioning pad 12 provides positioning of the workpiece 80 along the first direction z.

[0073] In some embodiments provided herein, the top support member 20 and the slider 30 are located between the end of the workpiece 80 facing away from the frame and the frame, and there is a distance between the top support member 20 and the end of the workpiece 80 facing away from the frame.

[0074] like Figure 3 As shown, the end of the top support member 20 facing away from the base plate 11 is located between the end of the workpiece 80 facing away from the base plate 11 and the base plate 11 in the first direction z, that is, the end of the workpiece 80 facing away from the base plate 11 protrudes from the end of the top support member 20 facing away from the base plate 11, and the end of the workpiece 80 facing away from the base plate 11 and the end of the top support member 20 facing away from the base plate 11 have a distance in the first direction z.

[0075] Therefore, when the workpiece 80 is milled or otherwise processed at one end away from the base plate 11, there is a distance between the top support member 20 and the processing tool to avoid the processing tool head, so that the clamping device 100 provided in the present application has the advantage of having less impact on the processing efficiency of the workpiece 80 while clamping the workpiece 80.

[0076] In some embodiments provided in the present application, the clamping device 100 also includes a plurality of first clamping members 41 and a plurality of first clamping driving members 42. The first clamping driving members 42 are arranged on the base 10, and the first clamping members 41 are arranged one by one on the first clamping driving members 42. The plurality of first clamping driving members 42 are arranged on the outside of the plurality of supporting members 20 to drive the plurality of first clamping members 41 to move toward each other and clamp against the outer contour of the workpiece 80.

[0077] like Figure 1As shown, multiple first clamping members 41 are provided on the outside of multiple supporting members 20, and the first clamping members 41 are arranged in a one-to-one correspondence with the supporting members 20. The first clamping driving member 42 can drive the first clamping members 41 and the corresponding supporting members 20 to move toward each other. The first clamping members 41 clamp against the outer contour of the workpiece 80 and the supporting members 20 support the inner contour of the workpiece 80, thereby achieving clamping of the inner and outer contours of the workpiece 80.

[0078] Therefore, the outer contour and inner contour of the workpiece 80 are clamped and fixed respectively by the first clamping member 41 and the top support member 20, which on the one hand ensures the positioning accuracy of the workpiece 80, and on the other hand improves the rigidity of the support for the workpiece 80, preventing the workpiece 80 from vibrating during processing and causing poor appearance.

[0079] In some embodiments provided herein, the clamping device 100 further includes a second clamping member 51 and a second clamping driving member 52 . The second clamping driving member 52 is disposed on the base 10 , and the second clamping member 51 is rotatably disposed on the second clamping driving member 52 .

[0080] The second clamping member 51 can be rotated to the side of the workpiece 80 away from the base 10 and the second clamping member 51 is pressed against the end of the workpiece 80 away from the base 10 by the second clamping driving member 52;

[0081] The second clamping member 51 can be rotated to the outside of the outer contour of the workpiece 80 to avoid the workpiece 80 .

[0082] like Figure 1 As shown, the second clamping member 51 is located on the side of the workpiece 80 away from the base 10, and the second clamping member 51 extends along the first direction z relative to the rotation axis of the second clamping drive member 52, so that the second clamping member 51 can be rotated to the side of the workpiece 80 away from the base 10, or rotated to the outside of the outer contour of the workpiece 80.

[0083] When the second clamping member 51 rotates to the side of the workpiece 80 away from the base 10, the projection of the second clamping member 51 in the first direction z partially coincides with the projection contour of the workpiece 80 in the first direction z, and the second clamping member 51 is driven by the second clamping driving member 52 to move along the first direction z toward the workpiece 80 until the second clamping member 51 abuts against the end of the workpiece 80 away from the base plate 11.

[0084] Therefore, the second clamping member 51 can limit the movement freedom of the workpiece 80 in the first direction z, and the circumferential rotational freedom of the workpiece 80 in the second direction x and the circumferential rotational freedom of the workpiece 80 in the third direction y, thereby achieving complete fixation of the workpiece 80.

[0085] When the second clamping member 51 rotates to the outside of the outer contour of the workpiece 80, the projection of the second clamping member 51 and the second clamping drive member 52 in the first direction z is located outside the projection contour of the workpiece 80 in the first direction z, so as to avoid the workpiece 80 when the workpiece 80 is placed on the outside of multiple supporting members 20, or when the workpiece 80 is taken out of the clamping device 100 provided in this application.

[0086] In some embodiments provided in the present application, the clamping device 100 further includes a push block 70 , which is disposed on the side of the workpiece 80 facing away from the base 10 . The push block 70 can move toward the base 10 to press against the end of the workpiece 80 facing away from the base 10 .

[0087] like Figure 4 As shown, the push block 70 is arranged on one side of the base 10 along the first direction z, and the top support member 20 and the slider 30 are located between the push block 70 and the bottom plate 11. The push block 70 can move along the first direction z close to the bottom plate 11 until the push block 70 pushes the workpiece 80 against the bottom plate 11.

[0088] Therefore, on the one hand, the push block 70 pushes the workpiece 80 against the side of the base plate 11 toward the top support member 20, which can limit the movement freedom of the workpiece 80 in the first direction z, and limit the circumferential rotational freedom of the workpiece 80 in the second direction x and the circumferential rotational freedom of the workpiece 80 in the third direction y, thereby achieving complete fixation of the workpiece 80. On the other hand, the push block 70 is located on the side of the workpiece 80 away from the base plate 11, so that the processing device can process the side walls of the workpiece 80 in the second direction x and the third direction y, so that the clamping device 100 provided in the present application has the advantage of having less impact on the processing efficiency of the workpiece 80 while clamping the workpiece 80.

[0089] The processing equipment provided by this application is described below.

[0090] The processing equipment provided in this application includes a clamping device 100 and a processing device (not shown in the figure), the clamping device 100 is the clamping device 100 of any of the above embodiments, and the processing device can move toward the clamping device 100 to process the workpiece 80 fixed by the clamping device 100.

[0091] Optionally, the processing device includes a feeding mechanism and a processing tool. The feeding mechanism can move the processing tool to the surface of the workpiece 80 fixed in the clamping device 100 to perform processing operations on the workpiece 80.

[0092] The clamping device 100 provided herein secures the workpiece 80 by supporting the inner contour of the workpiece 80 with multiple supporting members 20. This ensures that the end of the workpiece 80 facing away from the clamping device 100 and the sidewalls of the workpiece 80 are unobstructed. This allows the machining device to simultaneously machine the end of the workpiece facing away from the clamping device 100 and the sidewalls of the workpiece 80 while the clamping device 100 holds the workpiece 80. This reduces the number of clamping operations required for the workpiece 80, resulting in the machining equipment provided herein having the advantages of high machining precision and efficiency for hollow workpieces 80.

[0093] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
