[0029] As shown in Figures 1 to 3 The embodiments of the present application provide a clamping structure 100 including a first clamping assembly 1, a connecting assembly 2, a driving assembly 3 and an adjusting assembly 4.

[0030] For the convenience of subsequent reading, the present application introduces a first direction X, a second direction Y and a third direction Z to describe the embodiments of the present application. The first direction X, the second direction Y and the third direction Z can be three mutually non-parallel straight line directions in space; further, the first direction X, the second direction Y and the third direction Z can be three mutually perpendicular directions in a three-dimensional coordinate system (three-dimensional Cartesian coordinate system). In the subsequent embodiments, the first direction X is taken as the X-axis direction of the coordinate axis of the three-dimensional coordinate system, the second direction Y is taken as the Y-axis direction of the coordinate axis of the three-dimensional coordinate system, and the third direction Z is taken as the Z-axis direction of the coordinate axis of the three-dimensional coordinate system.

[0031] In the first direction X, the first clamping assembly 1 comprises two first clamping pieces 11 arranged at intervals. The driving assembly 3 is drivingly connected to at least one first clamping piece 11 through the connecting assembly 2, for driving at least one first clamping piece 11 of the two first clamping pieces 11 to move relative to the other first clamping piece 11 in the first direction X. The first clamping piece 11 is rotatably connected to the connecting assembly 2 through the adjusting assembly 4, and the first clamping piece 11 has at least a first rotation axis L1 and a second rotation axis L2, and the adjusting assembly 4 is configured to enable the first clamping piece 11 to rotate around the first rotation axis L1 and the second rotation axis L2, and the extension direction of the first rotation axis L1 is parallel to the second direction Y, and the direction of the second rotation axis L2 is parallel to the third direction Z.

[0032] In the embodiment, the two first clamping pieces 11 clamp the workpiece 300 to be machined in the first direction X, wherein one first clamping piece 11 connected to the driving assembly 3 is rotatably connected to the connecting assembly 2, and the other first clamping piece 11 serves as a baffle and does not rotate relative to the workpiece 300 to be machined, and only the first clamping piece 11 driven by the driving assembly 3 abuts against the first clamping piece 11 serving as a baffle during machining. In this way, only one first clamping piece 11 is connected to the connecting assembly 2 and the driving assembly 3, which can avoid excessive interference of the tool with the workpiece 300 to be machined, so that the workpiece 300 can be machined on both sides in the first direction X in some cases. The driving assembly 3 can be a pneumatic cylinder, which can drive the first clamping piece 11 to move in the first direction X, and is not limited here.

[0033] The first clamping piece 11 can be composed of two push blocks connected to each other, one of the two push blocks abuts against the workpiece 300 to be machined and can be a glass fiber push block to form a buffer between the workpiece 300 to be machined and the glass fiber push block, and the other push block is connected to the connecting assembly 2. The two push blocks can form a cavity to accommodate the adjusting assembly 4.

[0034] It can be understood that the first clamping piece 11 can rotate around the first rotation axis L1 and the second rotation axis L2 to better fit the workpiece 300 to be machined, so that the workpiece 300 to be machined can be clamped better, and different workpieces 300 can be adapted to, and the workpiece 300 will not be deformed due to excessive clamping to affect machining.

[0035] In other embodiments, both of the first clamping pieces 11 are rotatably connected to the connecting assembly 2 to clamp the workpiece 300 to be machined better.

[0036] As Figures 2 to 4As shown, in an embodiment, the adjusting assembly 4 comprises an adjusting body 41, and the first clamping member 11 is rotatably connected to the adjusting body 41, and the first clamping member 11 is configured to be rotatable about the first rotation axis L1 relative to the adjusting body 41.

[0037] The adjusting body 41 is rotatably connected to the connecting assembly 2, and the adjusting body 41 is configured to be rotatable about the second rotation axis L2 relative to the connecting assembly 2.

[0038] In the embodiment, the adjusting body 41 can be provided as a block, which is located between the connecting assembly 2 and the first clamping member 11, so as to enable the first clamping member 11 to be rotatable about the first rotation axis L1 relative to the adjusting body 41. Meanwhile, the adjusting body 41 is rotatable about the second rotation axis L2 relative to the connecting assembly 2, so as to drive the first clamping member 11 to rotate about the second rotation axis L2 relative to the connecting assembly 2.

[0039] In an embodiment, the adjusting assembly 4 further comprises a first adjusting member 42 and a second adjusting member 43, the first adjusting member 42 extends in parallel to the second direction Y, the first adjusting member 42 is connected to the first clamping member 11, and the first clamping member 11 is rotatably connected to the adjusting body 41 through the first adjusting member 42.

[0040] The second adjusting member 43 extends in parallel to the third direction Z, the second adjusting member 43 is connected to the adjusting body 41, and the adjusting body 41 is rotatably connected to the connecting assembly 2 through the second adjusting member 43.

[0041] In the embodiment, the first adjusting member 42 and the second adjusting member 43 can be provided as shafts, which are connected to the adjusting body 41. Along the first direction X and the third direction Z, the first adjusting member 42 can be limited, so as to enable the first clamping member 11 to rotate about the first rotation axis L1 relative to the connecting assembly 2 through the first adjusting member 42. Similarly, along the first direction X and the second direction Y, the second adjusting member 43 can be limited, so as to enable the adjusting body 41 to rotate about the second rotation axis L2 relative to the connecting assembly 2 through the second adjusting member 43, and thus enable the first clamping member 11 connected to the adjusting body 41 to rotate about the second rotation axis L2 relative to the connecting assembly 2.

[0042] It can be understood that the first adjusting member 42 and the second adjusting member 43 are provided to enable the first clamping member 11 to rotate relative to the connecting assembly 2 to adjust the fitting state between the first clamping member 11 and the workpiece 300 to be processed, so that the first clamping member 11 clamps the workpiece 300 to be processed better.

[0043] In an embodiment, the adjusting body 41 is provided with a first through hole 410 and a second through hole 411, the first adjusting member 42 can pass through the first through hole 410 and rotate in the first through hole 410. The second adjusting member 43 can pass through the second through hole 411 and rotate in the second through hole 411.

[0044] In the embodiment, the first through hole 410 and the second through hole 411 can be provided for the first adjusting member 42 and the second adjusting member 43. In the first direction X and the third direction Z, the surface of the first adjusting member 42 abuts against the hole wall of the first through hole 410, so that the first adjusting member 42 is limited in displacement in the first direction X and the second direction Y, thereby enabling the first clamping member 11 to rotate relative to the connecting assembly 2 about the first rotation axis L1 through the first adjusting member 42. Similarly, in the first direction X and the second direction Y, the surface of the second adjusting member 43 abuts against the hole wall of the second through hole 411, so that the second adjusting member 43 is limited in displacement in the first direction X and the third direction Z, thereby enabling the adjusting body 41 to rotate relative to the connecting assembly 2 about the second rotation axis L2 through the second adjusting member 43, so that the first clamping member 11 connected to the adjusting body 41 can also rotate relative to the connecting assembly 2 about the second rotation axis L2.

[0045] It can be understood that the through holes are provided so that the first adjusting member 42 and the second adjusting member 43 can only rotate relative to the connecting body, avoiding the movement of the first clamping member 11 or the adjusting body 41 under other forces to change the clamping position, so that the clamping effect is not good.

[0046] As shown in Figure 5 , and referring to Figure 2 and Figure 3 , in an embodiment, the clamping structure 100 further comprises a limiting assembly 5 located between the connecting assembly 2 and the first clamping member 11, the limiting assembly 5 can limit the rotation of the first clamping member 11 about the second rotation axis L2.

[0047] In the embodiment, the limiting assembly 5 can include two limiting members 51 spaced apart in the second direction Y, one end of the limiting member 51 can movably abut against the first clamping member 11 to limit the rotation of the first clamping member 11 about the second rotation axis L2.

[0048] Understandably, since the clamping force of the first clamping member 11 at the end away from the driving component 3 is slightly less than that at the end of the first clamping member 11 near the driving component 3, the force on both ends of the first clamping member 11 along the third direction Z can be made uniform by setting the second adjusting member 43. However, the connecting component 2 is set along the second direction Y, and one end of the connecting component 2 is connected to the driving component 3, and the other end is connected to the first clamping component 1. This results in some workpieces 300 having thin walls at the end away from the driving component 3 in the second direction Y, requiring a smaller clamping force. Therefore, by using two limiting members 51 spaced apart along the second direction Y, the clamping force at the end of the first clamping member 11 away from the driving component 3 can be made less than the clamping force at the end of the first clamping member 11 near the driving component 3, while also ensuring good clamping.

[0049] In one embodiment, the connecting component 2 is provided with an adjustment hole 20. Along the first direction X, one end of the limiting member 51 can extend into the adjustment hole 20 and move relative to the first adjusting member 42, while the other end is movably abutting against the first clamping member 11.

[0050] In this embodiment, each limiting member 51 can extend along the first direction X. The limiting member 51 can be a screw. The adjustment hole 20 on the connecting component 2 can be a threaded hole. One end of the limiting member 51 can be threadedly connected to the connecting component 2, and the other end can be moved to abut against the first clamping member 11 according to the actual situation to limit the rotation of the first clamping member 11 around the second rotation axis L2.

[0051] Understandably, this makes the connection of the limiting component 5 more stable, enabling it to play a reliable limiting role and ensuring good clamping during processing.

[0052] In one embodiment, the clamping structure 100 further includes a support member 6, which is connected to the connecting component 2, and the end of the connecting component 2 away from the first clamping component 1 abuts against the support member 6.

[0053] In this embodiment, the support member 6 can be a block-shaped object that can support the connecting component 2, and no further restrictions are imposed.

[0054] Understandably, because the drive assembly 3 drives the clamping assembly to clamp, the workpiece 300 will exert a certain force on the drive assembly 3 along the third direction Z. Long-term use may easily lead to damage to the drive assembly 3. The support member 6 is provided to reduce the force on the drive assembly 3 and extend the service life of the drive assembly 3.

[0055] like Figure 6 and Figure 7 As shown, this application embodiment also provides a fixture 200, which includes the clamping structure 100 and fixture body 201 as described above, with the clamping structure 100 connected to the fixture body 201.

[0056] In this embodiment, the first clamping members 11 arranged at intervals along the first direction X in the clamping structure 100 clamp the workpiece 300 in the first direction X. At the same time, only one side of the first clamping member 11 is connected to the drive assembly 3 and the adjustment assembly 4 for better processing.

[0057] It is understandable that the fixture 200 can better clamp the workpiece 300 to be processed. At the same time, the fixture 200 with the above-mentioned clamping structure 100 can facilitate processing and avoid tool interference that prevents processing in some cases.

[0058] In one embodiment, the fixture 200 further includes a second clamping assembly 202, which clamps the workpiece 300 along the third direction Z.

[0059] In this embodiment, the second clamping assembly 202 includes two second clamping members 2021 spaced apart along the third direction Z. The two second clamping members 2021 can clamp the workpiece 300 along the third direction Z. One of the second clamping members 2021 can be connected to a driving member to drive the second clamping member 2021 to move along the third direction Z, so that the second clamping assembly 202 can clamp the workpiece 300 to be processed according to the actual processing situation.

[0060] In one embodiment, the fixture 200 further includes a third clamping assembly 203. The fixture body 201 includes a base 204. The third clamping assembly 203 is connected to the base 204 and is used to clamp the workpiece 300 onto the base 204.

[0061] In this embodiment, along the second direction Y, the workpiece 300 is placed on and connected to the base 204. The third clamping assembly 203 may include multiple third clamping members 2031, which may be provided according to the shape of the workpiece 300, so as to press the workpiece 300 onto the base 204, ensuring that the workpiece 300 is relatively fixed to the base 204 during the processing, and the processing is firm and reliable.

[0062] The specific embodiments of this application have been described above with reference to the accompanying drawings. However, those skilled in the art will understand that various changes and substitutions can be made to the specific embodiments of this application without departing from the spirit and scope of this application. All such changes and substitutions fall within the scope defined by this application.
