[0055] Clamping devices are commonly used in machining, manufacturing, and maintenance. The function of a clamping device is to stably fix a workpiece on related equipment, such as welding equipment, for related operations. With the development of new energy technologies, batteries are increasingly widely used, and clamping devices are also often used in the manufacturing process of batteries.

[0056] In the manufacturing process of batteries, the applicability of clamping devices has an important impact on the overall production efficiency and cost of batteries. For example, before continuing to weld a workpiece, it is necessary to first fix the workpiece through a clamping device to improve the welding quality.

[0057] Batteries include a large number of components with different structural sizes. Currently, existing clamping devices usually have limitations and cannot use a single clamping device to simultaneously meet the clamping requirements of components with different structural sizes in a battery. It is necessary to switch different clamping devices to clamp components with different structural sizes in the battery, which will lead to a reduction in the overall production efficiency of the battery and an increase in costs.

[0058] Based on the above considerations, an embodiment of the present application provides a clamping device. The clamping device includes a base, a first clamping component, and a second clamping component. The first clamping component is movably connected to the base and is arranged to be able to move along a first direction, and the second clamping component is movably connected to the base and is arranged to be able to move along a second direction. Among them, at least one of the first clamping component and the second clamping component is configured to be able to telescopically set along a third direction, and the first direction, the second direction, and the third direction intersect pairwise.

[0059] The clamping device of the above technical solution can adjust its own clamping range in the first direction, the second direction, and the third direction, thereby greatly enriching the types of workpieces that the clamping device can clamp and effectively improving the applicability of the clamping device. In addition, by setting the base, there is no need to additionally introduce an external bearing mechanism to bear the first clamping component and the second clamping component, which can improve the ease of use of the clamping device.

[0060] First, the clamping device provided by the embodiment of the present application will be introduced below in conjunction with the drawings. Figure 1 A three-dimensional structure diagram of a clamping device provided by some embodiments of the present application, Figure 2 A top view structure diagram of a clamping device provided by some embodiments of the present application, Figure 3 is Figure 2 A cross-sectional structure diagram along A-A, Figure 4 is Figure 3 A structure diagram of the base and the first clamping component in a separated state of the cross-section shown;

[0061] Refer to Figures 1 to 4, embodiments of the present application provide a clamping device, which includes a base 10, a first clamping component 20, and a second clamping component 30. The first clamping component 20 is movably connected to the base 10 and is arranged to be movable along a first direction X. The second clamping component 30 is movably connected to the base 10 and is arranged to be movable along a second direction Y. Among them, at least one of the first clamping component 20 and the second clamping component 30 is configured to be telescopically arranged along a third direction Z, and the first direction X, the second direction Y, and the third direction Z intersect pairwise.

[0062] The clamping device is used to clamp workpieces in machining, manufacturing, and repair. Exemplarily, in the embodiments of the present application, the clamping device can be used to clamp relevant components in a battery during the manufacturing process of the battery.

[0063] The base 10 is mainly used to carry other related components such as the first clamping component 20 and the second clamping component 30 in the clamping device, so as to improve the stability of the first clamping component 20 and the second clamping component 30 during the process of clamping workpieces. Optionally, the base 10 can be made of, but not limited to, metal or non-metal materials. For example, the metal material can be copper, aluminum, or stainless steel, etc.; the non-metal material can be polyethylene, polypropylene, polyvinyl chloride, or wood, etc.

[0064] The first clamping component 20 can be directly connected to the base 10 or restricted on the base 10 through other components. The second clamping component 30 can be directly connected to the base 10 or restricted on the base 10 through other components.

[0065] At least one of the first clamping component 20 and the second clamping component 30 is configured to be telescopically arranged along the third direction Z. It can be understood that one of the first clamping component 20 and the second clamping component 30 is configured to be telescopically arranged along the third direction Z, or both the first clamping component 20 and the second clamping component 30 are configured to be telescopically arranged along the third direction Z.

[0066] As an example, when the first clamping component 20 can be telescopically arranged along the third direction Z, the first clamping component 20 can be, but not limited to, realized to be telescopically arranged along the third direction Z through a telescopic rod structure, a slide rail and slider structure, a lead screw structure, or an electric cylinder structure. When the second clamping component 30 can be telescopically arranged along the third direction Z, the second clamping component 30 can be, but not limited to, realized to be telescopically arranged along the third direction Z through a telescopic rod structure, a slide rail and slider structure, a lead screw structure, or an electric cylinder structure.

[0067] The structures of the first clamping component 20 and the second clamping component 30 can be the same or different. As an example, the structures of the first clamping component 20 and the second clamping component 30 are the same to simplify the overall preparation process of the clamping device and help reduce costs.

[0068] Optionally, both the first clamping assembly 20 and the second clamping assembly 30 can be, but are not limited to, made of metal or non-metal materials. For example, the metal materials can be copper, aluminum, or stainless steel, etc.; the non-metal materials can be polyethylene, polypropylene, polyvinyl chloride, or wood, etc.

[0069] The number of the first clamping assemblies 20 can be one or more, and the number of the second clamping assemblies 30 can be one or more.

[0070] In some examples, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other in pairs.

[0071] Exemplarily, the first clamping assembly 20 can move along the first direction X, so as to adjust the clamping range of the clamping device along the first direction X to meet the clamping requirements of workpieces of different sizes in the first direction X; the second clamping assembly 30 can move along the second direction Y, so as to adjust the clamping range of the clamping device along the second direction Y to meet the clamping requirements of workpieces of different sizes in the second direction Y; at least one of the first clamping assembly 20 and the second clamping assembly 30 is configured to be telescopically arranged along the third direction Z, so as to adjust the clamping range of the clamping device along the third direction Z to meet the clamping requirements of workpieces of different sizes in the third direction Z.

[0072] The clamping device of the above technical solution can adjust its own clamping range along the first direction X, the second direction Y, and the third direction Z, so that the types of workpieces that the clamping device can clamp can be greatly enriched, and the applicability of the clamping device can be effectively improved. In addition, by providing the base 10, there is no need to additionally introduce an external bearing mechanism to bear the first clamping assembly 20 and the second clamping assembly 30, which can improve the usability of the clamping device.

[0073] In some examples, both the first clamping assembly 20 and the second clamping assembly 30 are configured to be telescopically arranged along the third direction Z, which can further improve the applicability of the clamping device.

[0074] In some embodiments, the first clamping assembly 20 includes a first connecting member 21 and a first supporting member 22. The first connecting member 21 is movably connected to the base 10, and the first supporting member 22 is connected to the first connecting member 21 and is configured to be telescopically arranged along the third direction Z.

[0075] Exemplarily, the first connecting member 21 is used to realize that the first clamping assembly 20 is movably connected to the base 10 and can move along the first direction X. The first connecting member 21 can be directly connected to the base 10 or restricted on the base 10 through other components. The first connecting member 21 can be, but is not limited to, a block-shaped structure or a columnar structure.

[0076] The first support member 22 is used to clamp the workpiece. The first support member 22 can be, but is not limited to, being telescopically arranged in the third direction Z through a telescopic rod structure, a slide rail and slider structure, a lead screw structure or an electric cylinder structure.

[0077] The first support member 22 can be detachably connected to the first connecting member 21, or can be integrally provided on the first connecting member 21. The first support member 22 can be directly connected to the first connecting member 21, or can be restricted on the first connecting member 21 through other components. As an example, the connection manner between the first support member 22 and the first connecting member 21 can be, but is not limited to, bolt connection, welding, riveting, snap connection or bonding, etc.

[0078] Optionally, both the first connecting member 21 and the first support member 22 can be, but are not limited to, made of metal or non-metal materials. For example, the metal materials can be copper, aluminum or stainless steel, etc.; the non-metal materials can be polyethylene, polypropylene, polyvinyl chloride or wood, etc. As an example, the first connecting member 21 and the first support member 22 can be made of the same material to simplify the preparation process flow and reduce costs.

[0079] Through the above technical solution, by providing the first connecting member 21 and the first support member 22 to respectively realize the function of moving the first clamping assembly 20 in the first direction X and the function of clamping the workpiece, the first connecting member 21 and the first support member 22 can be specifically designed according to the specific requirements of moving in the first direction X and clamping the workpiece, which can improve the design flexibility of the first clamping assembly 20 and is beneficial to reducing the overall preparation difficulty of the clamping device.

[0080] In some embodiments, the first support member 22 is rotatably arranged relative to the first connecting member 21, and the rotation axis of the first support member 22 is parallel to the first direction X.

[0081] Exemplarily, the rotation of the first support member 22 relative to the first connecting member 21 can be that the first support member 22 rotates one week relative to the first connecting member 21, or can be that the first support member 22 rotates less than one week relative to the first connecting member 21. For example, it can be, but is not limited to, 1 / 3 week, 1 / 2 week, 2 / 3 week or 3 / 4 week.

[0082] The first support member 22 and the first connecting member 21 are rotatably connected through a rotating member. Exemplarily, the rotating member can be arranged on the first support member 22, and a mating member corresponding to the rotating member is arranged on the first connecting member 21. The rotating member and the mating member cooperate to achieve the rotational connection between the first support member 22 and the first connecting member 21; the rotating member can be arranged on the first connecting member 21, and a mating member corresponding to the rotating member is arranged on the first support member 22. The rotating member and the mating member cooperate to achieve the rotational connection between the first support member 22 and the first connecting member 21. The rotating member can be, but is not limited to, a rotating shaft or a turntable, etc., and the mating member can be, but is not limited to, a through hole or a bearing, etc.

[0083] The first support member 22 of the above technical solution can rotate relative to the first connecting member 21, and the rotation axis of the first support member 22 is parallel to the first direction X, so that the clamping range of the first clamping assembly 20 can be further increased, which helps to further improve the applicability of the clamping device.

[0084] In some examples, a damping member can be arranged at the rotational connection between the first support member 22 and the first connecting member 21. The damping member is used to increase the friction force between the first support member 22 and the first connecting member 21 to reduce the risk of the first support member 22 shaking during the process of clamping the workpiece, so as to improve the reliability of the clamping device.

[0085] Figure 5 A schematic perspective view of another clamping device provided by some embodiments of the present application Figure 6 is Figure 5 a partial enlarged structural view of the H position of

[0086] Continue to refer to Figure 5 and Figure 6 , in some embodiments, the first clamping assembly 20 further includes a first fastening member 23. The first fastening member 23 is connected between the first connecting member 21 and the first support member 22 and is used to fix the first support member 22.

[0087] Exemplarily, when the first support member 22 rotates to a certain extent and clamps the workpiece, the first support member 22 is fixed by the first fastening member 23 to reduce the risk of the first support member 22 shaking during the process of clamping the workpiece.

[0088] In some examples, the first fastening member 23 may be a fastening bolt. An installation portion corresponding to the fastening bolt is provided on the first connecting member 21. The fastening bolt is installed in the installation portion and can move closer to or away from the first supporting member 22. When it is necessary to fix the first supporting member 22, rotate the fastening bolt so that the fastening bolt moves in a direction closer to the first supporting member 22 and abuts against the first supporting member 22 to limit the movement of the first supporting member 22. When it is necessary to rotate the first supporting member 22, rotate the fastening bolt so that the fastening bolt moves in a direction away from the first supporting member 22, so that the fastening bolt disengages from the first supporting member 22 to restore the rotatable state of the first supporting member 22.

[0089] In other examples, the first fastening member 23 may be a fastening pin, and the fastening pin is detachably connected between the first connecting member 21 and the first supporting member 22. When it is necessary to fix the first supporting member 22, insert the fastening pin into the gap between the first connecting member 21 and the first supporting member 22 to limit the movement of the first supporting member 22. When it is necessary to rotate the first supporting member 22, take out the fastening pin from the gap between the first connecting member 21 and the first supporting member 22 to restore the rotatable state of the first supporting member 22.

[0090] The above technical solution can reduce the risk of the first supporting member 22 shaking during the process of clamping a workpiece by introducing the first fastening member 23, so as to improve the reliability of the clamping device.

[0091] In some embodiments, the first supporting member 22 includes a first fixing member 221 and a first movable member 222. The first fixing member 221 is connected to the first connecting member 21, and the first movable member 222 is movably disposed inside the first fixing member 221 along the third direction Z.

[0092] Exemplarily, the first movable member 222 is movably disposed inside the first fixing member 221 along the third direction Z. It can be understood that the dimension of the first fixing member 221 in the direction perpendicular to the third direction Z is larger than the dimension of the first movable member 222 in the direction perpendicular to the third direction Z.

[0093] The first fixing member 221 is connected between the first connecting member 21 and the first movable member 222, and the relatively large dimension of the first fixing member 221 in the direction perpendicular to the third direction Z helps to improve the overall structural stability of the first supporting member 22.

[0094] The first movable member 222 is located on the side of the first fixed member 221 away from the first connecting member 21. The dimension of the first movable member 222 in the direction perpendicular to the third direction Z is small, so that when the first movable member 222 clamps a workpiece with a complex structure, it can better avoid the relevant structures on the workpiece and reduce the risk of the first support member 22 damaging the workpiece.

[0095] The first movable member 222 can be detachably connected to the first fixed member 221 or integrally provided on the first fixed member 221. The first movable member 222 can be directly connected to the first fixed member 221 or restricted on the first fixed member 221 through other components.

[0096] Optionally, both the first fixed member 221 and the first movable member 222 can be, but are not limited to, made of metal or non-metal materials. For example, the metal materials can be copper, aluminum, or stainless steel, etc.; the non-metal materials can be polyethylene, polypropylene, polyvinyl chloride, or wood, etc. As an example, the first fixed member 221 and the first movable member 222 can be made of the same material to simplify the preparation process flow and reduce costs.

[0097] In this way, the above technical solution can not only improve the overall structural stability of the first support member 22, but also reduce the risk of the first support member 22 damaging the workpiece.

[0098] In some embodiments, the first support member 22 includes a first fixed member 221 and a first movable member 222. The first fixed member 221 is connected to the first connecting member 21, and the first fixed member 221 is movably disposed inside the first movable member 222 along the third direction Z.

[0099] In some embodiments, a first spring buckle 223 is provided on one of the first movable member 222 and the first fixed member 221, and a first clamping portion 224 is provided on the other of the first movable member 222 and the first fixed member 221. The first spring buckle 223 is used to cooperate with the first clamping portion 224 to fix the first movable member 222.

[0100] Exemplarily, the first spring buckle 223 can be provided on the first movable member 222 and the first clamping portion 224 can be provided on the first fixed member 221; or the first spring buckle 223 can be provided on the first fixed member 221 and the first clamping portion 224 can be provided on the first movable member 222. When the first movable member 222 moves to a preset distance, the first spring buckle 223 is clamped and cooperated with the first clamping portion 224 to limit the movement of the first movable member 222 component; when the first movable member 222 needs to be moved, the clamping between the first spring buckle 223 and the first clamping portion 224 is released to restore the movable state of the first movable member 222.

[0101] Optionally, the first clamping portion 224 may be, but is not limited to, a through hole, a groove, or the like.

[0102] The above technical solution can reduce the risk of the first movable member 222 moving during the process of clamping the workpiece, so as to further improve the reliability of the clamping device.

[0103] In some examples, a first spring buckle 223 is provided on the first movable member 222, a first clamping portion 224 is provided on the first fixing member 221, and the first clamping portion 224 is a through hole that penetrates the side wall of the first fixing member 221. With such a setting, when it is necessary to move the first movable member 222, it is more convenient to release the clamping between the first spring buckle 223 and the first clamping portion 224, thereby improving the usability of the clamping device.

[0104] In some examples, the number of the first clamping portions 224 is multiple, and the multiple first clamping portions 224 are arranged at intervals along the third direction Z. The cooperation between the first spring buckle 223 and the multiple first clamping portions 224 can form a multi-stage clamping structure to fix the first movable member 222 when it moves different distances.

[0105] In some embodiments, in the third direction Z and in the direction away from the base 10, the size of the first end portion 225 of the first support member 22 away from the first connecting member 21 in the direction perpendicular to the third direction Z gradually decreases.

[0106] Exemplarily, the first support member 22 may be a rod-shaped structure, and the size of the first end portion 225 of the first support member 22 away from the first connecting member 21 in the direction perpendicular to the third direction Z can be understood as the thickness of the first end portion 225 of the first support member 22 away from the first connecting member 21.

[0107] Optionally, the projection shape of the first support member 22 along the third direction Z may be, but is not limited to, a circle, a rectangle, a triangle, an ellipse, or the like.

[0108] The above technical solution can enable the first support member 22 to better avoid the relevant structures on the workpiece when clamping a workpiece with a complex structure, so as to reduce the risk of the first support member 22 damaging the workpiece.

[0109] In some embodiments, a first slideway 11 is formed on the base 10. The first slideway 11 is arranged on one side of the base 10 along the third direction Z and extends along the first direction X. At least part of the first clamping assembly 20 is movably inserted into the first slideway 11.

[0110] Exemplarily, the first slideway 11 can be detachably connected to the base 10 or integrally provided on the base 10. The first slideway 11 can be directly connected to the base 10 or restricted on the base 10 through other components.

[0111] In some examples, the first slideway 11 protrudes from one side surface of the base 10 along the third direction Z. A chute matching the first slideway 11 is provided on the first clamping assembly 20, and the chute is inserted into the first slideway 11.

[0112] The above technical solution can reduce the assembly difficulty between the first clamping assembly 20 and the base 10 by introducing the first slideway 11, which is beneficial to improving the overall preparation efficiency of the clamping device.

[0113] In some embodiments, the first slideway 11 is recessed with respect to one side surface of the base 10 along the third direction Z.

[0114] Exemplarily, the first slideway 11 is a groove structure, which is recessed with respect to one side surface of the base 10 along the third direction Z, and at least part of the first clamping assembly 20 is accommodated in the first slideway 11.

[0115] On the one hand, the above technical solution can reduce the space occupancy rate of the first clamping assembly 20, which helps to reduce the overall volume of the clamping device.

[0116] In some embodiments, the base 10 and the first slideway 11 are an integrally formed structure. Without introducing additional components, it can further simplify the overall preparation process of the clamping device and help reduce costs.

[0117] In some embodiments, a first channel 12 is further provided on the base 10. The first channel 12 is provided on at least one of two opposite side walls of the first slideway 11 along the second direction Y, and the first channel 12 extends along the first direction X. A first block 24 is provided on the first clamping assembly 20, and the first block 24 is movably inserted into the first channel 12.

[0118] Exemplarily, the first channel 12 can be provided on one of two opposite side walls of the first slideway 11 along the second direction Y, or the first channel 12 can be provided on two opposite side walls of the first slideway 11 along the second direction Y. The first block 24 is correspondingly arranged with the first channel 12, that is to say, the first block 24 is arranged on one side of the first clamping assembly 20 facing the first channel 12.

[0119] The above technical solution can limit the displacement of the first clamping assembly 20 along the third direction Z by inserting the first block 24 into the first channel 12, reduce the risk of the first clamping assembly 20 disengaging from the first slideway 11, and thus improve the reliability of the clamping device.

[0120] In some embodiments, the first clamping assembly 20 includes a first connecting member 21, a first supporting member 22, and a first clamping block 24. The first connecting member 21 is movably connected to the base 10. The first supporting member 22 is connected to the first connecting member 21 and is configured to be telescopically arranged along the third direction Z. The first clamping block 24 is connected to the first connecting member 21.

[0121] The first clamping block 24 can be detachably connected to the first connecting member 21 or integrally provided on the first connecting member 21. The first clamping block 24 can be directly connected to the first connecting member 21 or restricted on the first connecting member 21 through other components.

[0122] Optionally, both the first connecting member 21 and the first clamping block 24 can be made of, but are not limited to, metal or non-metal materials. For example, the metal material can be copper, aluminum, or stainless steel, etc.; the non-metal material can be polyethylene, polypropylene, polyvinyl chloride, or wood, etc. As an example, the first fixing member 221 and the first movable member 222 can be made of the same material to simplify the preparation process flow and reduce costs.

[0123] In some examples, the first connecting member 21 and the first clamping block 24 are an integrally formed structure. On the one hand, there is no need to connect the first connecting member 21 and the first clamping block 24 through an additional connecting process, which simplifies the manufacturing process flow. At the same time, compared with connecting the first connecting member 21 and the first clamping block 24 through an additional connecting process, the first connecting member 21 and the first clamping block 24 in an integrated structure have higher connection firmness.

[0124] In some embodiments, the first channel 12 includes a first sub-channel 121 and a second sub-channel 122. The first sub-channel 121 and the second sub-channel 122 are respectively arranged on two opposite side walls of the first slideway 11 along the second direction Y. The first clamping block 24 includes a first sub-clamping block 241 and a second sub-clamping block 242. The first sub-clamping block 241 and the second sub-clamping block 242 are respectively arranged on two opposite sides of the first clamping assembly 20 along the second direction Y. The first sub-clamping block 241 and the second sub-clamping block 242 are respectively movably inserted into the first sub-channel 121 and the second sub-channel 122.

[0125] Exemplarily, the structural shapes of the first channel 12 and the second channel can be the same or different. The structural shapes of the first sub-clamping block 241 and the second sub-clamping block 242 can be the same or different. Among them, the first sub-clamping block 241 is adapted to the structural shape of the first channel 12, and the second sub-clamping block 242 is adapted to the structural shape of the second channel.

[0126] In some examples, the structural shapes of the first sub-channel 121 and the second sub-channel 122 are the same, and the structural shapes of the first sub-block 241 and the second sub-block 242 are the same, which can simplify the preparation process flow and reduce costs.

[0127] The above technical solution can improve the limiting effect of the first block 24 on the displacement of the first clamping assembly 20 in the third direction Z, so as to further reduce the risk of the first clamping assembly 20 disengaging from the first slideway 11, thereby further improving the reliability of the clamping device.

[0128] In some embodiments, the clamping device includes two first clamping assemblies 20 and two second clamping assemblies 30. The two first clamping assemblies 20 are respectively arranged on both sides of the base 10 along the second direction Y, and the two second clamping assemblies 30 are respectively arranged on both sides of the base 10 along the first direction X.

[0129] Exemplarily, the base 10 can be a rectangular base, that is, the projection of the base 10 in the third direction Z is rectangular. The two first clamping assemblies 20 are respectively arranged on opposite side edges of the base 10 along the second direction Y, and the two second clamping assemblies 30 are respectively arranged on opposite side edges of the base 10 along the first direction X.

[0130] It can be understood that the more the number of the first clamping assemblies 20 and the second clamping assemblies 30, the higher the clamping stability of the clamping device, and at the same time, the higher the structural complexity of the clamping device; the fewer the number of the first clamping assemblies 20 and the second clamping assemblies 30, the lower the clamping stability of the clamping device, and at the same time, the lower the structural complexity of the clamping device.

[0131] In this way, by arranging two first clamping assemblies 20 and two second clamping assemblies 30, the above technical solution can enable the clamping device to balance relatively high clamping stability and relatively low structural complexity.

[0132] In some embodiments, the second clamping assembly 30 includes a second connecting component and a second supporting component. The second connecting component is movably connected to the base 10, and the second supporting component is connected to the second connecting component and is configured to be telescopically arranged along the third direction Z.

[0133] Exemplarily, the second connecting component is used to realize that the second clamping assembly 30 is movably connected to the base 10 and can move along the first direction X. The second connecting component can be directly connected to the base 10 or restricted on the base 10 through other components. The second connecting component can be, but is not limited to, a block-shaped structure or a columnar structure.

[0134] The second support member is used to clamp the workpiece. The second support member can be, but is not limited to, being telescopically arranged in the third direction Z through a telescopic rod structure, a slide rail and slider structure, a lead screw structure or an electric cylinder structure.

[0135] The second support member can be detachably connected to the second connecting member, or can be integrally provided on the second connecting member. The second support member can be directly connected to the second connecting member, or can be restricted on the second connecting member through other components. As an example, the connection manner between the second support member and the second connecting member can be, but is not limited to, bolt connection, welding, riveting, snap connection or bonding, etc.

[0136] Optionally, both the second connecting member and the second support member can be, but are not limited to, made of metal or non-metal materials. For example, the metal material can be copper, aluminum or stainless steel, etc.; the non-metal material can be polyethylene, polypropylene, polyvinyl chloride or wood, etc. As an example, the second connecting member and the second support member can be made of the same material to simplify the preparation process flow and reduce costs.

[0137] The above technical solution realizes the functions of moving the second clamping assembly 30 in the first direction X and clamping the workpiece by setting the second connecting member and the second support member respectively, and can respectively perform targeted structural design on the second connecting member and the second support member according to the specific requirements of moving in the first direction X and clamping the workpiece, which can improve the design flexibility of the second clamping assembly 30 and is beneficial to reducing the overall preparation difficulty of the clamping device.

[0138] In some embodiments, the second support member is rotatably arranged relative to the second connecting member, and the rotation axis of the second support member is parallel to the second direction Y.

[0139] Exemplarily, the rotation of the second support member relative to the second connecting member can be that the second support member rotates one week relative to the second connecting member, or can be that the second support member rotates less than one week relative to the second connecting member. For example, it can be, but is not limited to, 1 / 3 week, 1 / 2 week, 2 / 3 week or 3 / 4 week.

[0140] The second support member and the second connecting member are rotationally connected through a rotating member. Exemplarily, the rotating member can be arranged on the second support member, and a mating member corresponding to the rotating member is arranged on the second connecting member, and the rotating member and the mating member cooperate to realize the rotational connection between the second support member and the second connecting member; the rotating member can be arranged on the second connecting member, and a mating member corresponding to the rotating member is arranged on the second support member, and the rotating member and the mating member cooperate to realize the rotational connection between the second support member and the second connecting member. The rotating member can be, but is not limited to, a rotating shaft or a turntable, etc., and the mating member can be, but is not limited to, a through hole or a bearing, etc.

[0141] The second support member of the above technical solution can rotate relative to the second connecting member, and the rotation axis of the second support member is parallel to the second direction Y, so that the clamping range of the second clamping assembly 30 can be further improved, which helps to further improve the applicability of the clamping device.

[0142] In some examples, a damping member may be provided at the rotational connection between the second support member and the second connecting member. The damping member is used to increase the friction force between the second support member and the second connecting member, so as to reduce the risk of the second support member shaking during the process of clamping the workpiece, and improve the reliability of the clamping device.

[0143] In some embodiments, the second clamping assembly 30 further includes a second fastening member. The second fastening member is connected between the second connecting member and the second support member and is used to fix the second support member.

[0144] Exemplarily, when the second support member rotates to a certain extent and clamps the workpiece, the second support member is fixed by the second fastening member to reduce the risk of the second support member shaking during the process of clamping the workpiece.

[0145] In some examples, the second fastening member may be a fastening bolt. An installation portion corresponding to the fastening bolt is provided on the second connecting member. The fastening bolt is installed in the installation portion, and the fastening bolt can move close to or away from the second support member. When it is necessary to fix the second support member, rotate the fastening bolt so that the fastening bolt moves in the direction close to the second support member and abuts against the second support member to limit the movement of the second support member; when it is necessary to rotate the second support member, rotate the fastening bolt so that the fastening bolt moves in the direction away from the second support member, so that the fastening bolt disengages from the second support member to restore the rotatable state of the second support member.

[0146] In some other examples, the second fastening member may be a fastening pin. The fastening pin is detachably connected between the second connecting member and the second support member. When it is necessary to fix the second support member, insert the fastening pin into the gap between the second connecting member and the second support member to limit the movement of the second support member; when it is necessary to rotate the second support member, take out the fastening pin from the gap between the second connecting member and the second support member to restore the rotatable state of the second support member.

[0147] The above technical solution can reduce the risk of the second support member shaking during the process of clamping the workpiece by introducing the second fastening member, so as to improve the reliability of the clamping device.

[0148] In some embodiments, the second support member includes a second fixing member and a second movable member. The second fixing member is connected to the second connecting member, and the second movable member is movably disposed through the interior of the second fixing member along the third direction Z.

[0149] Exemplarily, the second movable member is movably disposed through the interior of the second fixing member along the third direction Z. It can be understood that the dimension of the second fixing member in the direction perpendicular to the third direction Z is greater than the dimension of the second movable member in the direction perpendicular to the third direction Z.

[0150] The second fixing member is connected between the second connecting member and the second movable member, and the relatively larger dimension of the second fixing member in the direction perpendicular to the third direction Z helps to improve the overall structural stability of the second support member.

[0151] The second movable member is located on the side of the second fixing member away from the second connecting member, and the relatively smaller dimension of the second movable member in the direction perpendicular to the third direction Z enables the second movable member to better avoid the relevant structures on the workpiece when clamping a workpiece with a complex structure, reducing the risk of the second support member damaging the workpiece.

[0152] The second movable member can be detachably connected to the second fixing member or integrally provided on the second fixing member. The second movable member can be directly connected to the second fixing member or restricted on the second fixing member through other components.

[0153] Optionally, both the second fixing member and the second movable member can be but are not limited to being made of metal or non-metal materials. For example, the metal material can be copper, aluminum, or stainless steel, etc.; the non-metal material can be polyethylene, polypropylene, polyvinyl chloride, or wood, etc. As an example, the second fixing member and the second movable member can be made of the same material to simplify the preparation process flow and reduce costs.

[0154] Thus, the above technical solution can not only improve the overall structural stability of the second support member but also reduce the risk of the second support member damaging the workpiece.

[0155] In some embodiments, the second support member includes a second fixing member and a second movable member. The second fixing member is connected to the second connecting member, and the second fixing member is movably disposed through the interior of the second movable member along the third direction Z.

[0156] In some embodiments, a second spring buckle is provided on one of the second movable member and the second fixing member, and a second engaging portion is provided on the other of the second movable member and the second fixing member. The second spring buckle is used to cooperate with the second engaging portion to fix the second movable member.

[0157] Exemplarily, a second spring buckle may be provided on the second movable member, and a second engaging portion may be provided on the second fixing member; alternatively, a second spring buckle may be provided on the second fixing member, and a second engaging portion may be provided on the second movable member. When the second movable member moves to a preset distance, the second spring buckle is engaged with the second engaging portion to limit the movement of the second movable member; when it is necessary to move the second movable member, the engagement between the second spring buckle and the second engaging portion is released to restore the movable state of the second movable member.

[0158] Optionally, the second engaging portion may be, but is not limited to, a through hole or a groove, etc.

[0159] The above technical solution can reduce the risk of the second movable member moving during the process of clamping the workpiece, so as to further improve the reliability of the clamping device.

[0160] In some examples, a second spring buckle is provided on the second movable member, a second engaging portion is provided on the second fixing member, and the second engaging portion is a through hole that penetrates the side wall of the second fixing member. With such a setting, when it is necessary to move the second movable member, it is more convenient to release the engagement between the second spring buckle and the second engaging portion, thereby improving the usability of the clamping device.

[0161] In some examples, the number of the second engaging portions is multiple, and the multiple second engaging portions are arranged at intervals along the third direction Z. The cooperation between the second spring buckle and the multiple second engaging portions can form a multi-stage engaging structure to fix the second movable member when it moves at multiple different distances.

[0162] In some embodiments, in the third direction Z and in the direction away from the base 10, the dimension of the second end portion of the second support member away from the second connecting member in the direction perpendicular to the third direction Z gradually decreases.

[0163] Exemplarily, the second support member may be a rod-shaped structure, and the dimension of the second end portion of the second support member away from the second connecting member in the direction perpendicular to the third direction Z can be understood as the thickness of the second end portion of the second support member away from the second connecting member.

[0164] Optionally, the projection shape of the second support member along the third direction Z may be, but is not limited to, a circle, a rectangle, a triangle, an ellipse, etc.

[0165] The above technical solution can enable the second support member to better avoid the relevant structures on the workpiece when clamping a workpiece with a complex structure, so as to reduce the risk of the second support member damaging the workpiece.

[0166] In some embodiments, a second slideway is formed on the base 10. The second slideway is disposed on one side of the base 10 along the third direction Z and extends along the second direction Y. At least a part of the second clamping assembly 30 is movably inserted into the second slideway.

[0167] Exemplarily, the second slideway can be detachably connected to the base 10 or integrally provided on the base 10. The second slideway can be directly connected to the base 10 or restricted on the base 10 through other components.

[0168] In some examples, the second slideway protrudes from one side surface of the base 10 along the third direction Z, and a chute matching the second slideway is formed on the second clamping assembly 30. The chute is inserted into the second slideway.

[0169] Through the introduction of the second slideway, the above technical solution can reduce the assembly difficulty between the second clamping assembly 30 and the base 10, which is beneficial to improving the overall preparation efficiency of the clamping device.

[0170] In some embodiments, the second slideway is recessed with respect to one side surface of the base 10 along the third direction Z.

[0171] Exemplarily, the second slideway is a groove structure, which is recessed with respect to one side surface of the base 10 along the third direction Z, and at least a part of the second clamping assembly 30 is received in the second slideway.

[0172] On the one hand, the above technical solution can reduce the space occupancy rate of the second clamping assembly 30, which helps to reduce the overall volume of the clamping device.

[0173] In some embodiments, the base 10 and the second slideway are of an integrally formed structure. Without introducing additional components, it can further simplify the overall preparation process of the clamping device and help reduce costs.

[0174] In some embodiments, a second channel is further formed on the base 10. The second channel is disposed on at least one of two opposite side walls of the second slideway along the first direction X and extends along the first direction X. A second block is provided on the second clamping assembly 30, and the second block is movably inserted into the second channel.

[0175] Exemplarily, the second channel can be disposed on one of two opposite side walls of the second slideway along the first direction X, or the second channel can be disposed on two opposite side walls of the second slideway along the first direction X. The second block is correspondingly arranged with the second channel, that is, the second block is disposed on one side of the second clamping assembly 30 facing the second channel.

[0176] Through the introduction of the second clamping block, the insertion connection between the second clamping block and the second channel can limit the displacement of the second clamping assembly 30 in the third direction Z, reduce the risk of the second clamping assembly 30 disengaging from the second slideway, and thus improve the reliability of the clamping device.

[0177] In some embodiments, the second clamping assembly 30 includes a second connecting member, a second supporting member, and a second clamping block. The second connecting member is movably connected to the base 10. The second supporting member is connected to the second connecting member and is configured to be telescopically arranged along the third direction Z. The second clamping block is connected to the second connecting member.

[0178] The second clamping block can be detachably connected to the second connecting member or integrally provided on the second connecting member. The second clamping block can be directly connected to the second connecting member or restricted on the second connecting member through other components.

[0179] Optionally, both the second connecting member and the second clamping block can be made of, but are not limited to, metal or non-metal materials. For example, the metal material can be copper, aluminum, or stainless steel, etc.; the non-metal material can be polyethylene, polypropylene, polyvinyl chloride, or wood, etc. As an example, the second fixing member and the second moving member can be made of the same material to simplify the preparation process flow and reduce costs.

[0180] In some examples, the second connecting member and the second clamping block are of an integrally formed structure. On the one hand, there is no need to connect the second connecting member and the second clamping block through an additional connecting process, which simplifies the manufacturing process flow. At the same time, compared with connecting the second connecting member and the second clamping block through an additional connecting process, the second connecting member and the second clamping block in an integral structure have higher connection firmness.

[0181] In some embodiments, the second channel includes a third sub-channel and a fourth sub-channel. The third sub-channel and the fourth sub-channel are respectively arranged on two opposite side walls of the second slideway along the first direction X. The second clamping block includes a third sub-clamping block and a fourth sub-clamping block. The third sub-clamping block and the fourth sub-clamping block are respectively arranged on two opposite sides of the second clamping assembly 30 along the first direction X, and the third sub-clamping block and the fourth sub-clamping block are respectively movably inserted into the third sub-channel and the fourth sub-channel.

[0182] Exemplarily, the structural shapes of the second channel and the second channel can be the same or different. The structural shapes of the third sub-clamping block and the fourth sub-clamping block can be the same or different. Among them, the third sub-clamping block is adapted to the structural shape of the second channel, and the fourth sub-clamping block is adapted to the structural shape of the second channel.

[0183] In some examples, the third sub-channel and the fourth sub-channel have the same structural shape, and the third sub-block and the fourth sub-block have the same structural shape, which can simplify the preparation process flow and reduce costs.

[0184] The above technical solution can improve the limiting effect of the second block on the displacement of the second clamping assembly 30 in the third direction Z, so as to further reduce the risk of the second clamping assembly 30 disengaging from the second slideway, and further improve the reliability of the clamping device.

[0185] In some embodiments, the second slideway is communicated with the first slideway 11, which can facilitate the simultaneous integral molding of the second slideway and the first slideway 11, contribute to simplifying the preparation process of the clamping device, and reduce costs.

[0186] It can be understood that the second clamping assembly 30 in the embodiments of the present application can have the same structural principle as the first clamping assembly 20 provided in the embodiments of the present application.
