[0005] In the above technical solution, the first driving member connects the first clamping member and the first connecting seat, and the first driving member can drive the first clamping member to move relative to the first connecting seat along the first direction to cooperate with the second clamping member to clamp the workpiece. The first connecting seat can adjust its position on the base along the first direction, so that the first clamping assembly as a whole can follow the first connecting seat to adjust its position on the base along the first direction, thereby adjusting the minimum clamping distance between the first clamping member and the second clamping member, and then timely adjusting the minimum clamping distance of the fixture to adapt to the size of the workpiece. Such a structure only realizes the adaptation of the fixture to the workpiece by adjusting the position of the first connecting seat on the base along the first direction, thereby improving the adjustment efficiency of the fixture.

[0006] In some embodiments, the first clamping assembly further includes a locking accessory, which is configured to lock or unlock the first connecting seat and the base. By setting the locking accessory, the locking accessory can lock the position of the first connecting seat. When the first connecting seat is adjusted to the target position on the base, the first connecting seat can be locked by the locking accessory, so that the connection between the first connecting seat and the base is more stable; when the position of the first connecting seat needs to be adjusted, the position of the first connecting seat on the base can be adjusted by unlocking the locking accessory, thereby reducing the replacement of parts and achieving the adjustment of the minimum clamping distance between the first clamp and the second clamp, thereby improving the adjustment efficiency of the clamp.

[0007] In some embodiments, one of the first connection seat and the base is provided with a bar hole, and the other is provided with a first mounting hole, the extension direction of the bar hole is parallel to the first direction, and the locking accessory passes through the bar hole and cooperates with the first mounting hole.

The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order or a primary and secondary relationship.

[0046] Reference to "embodiment" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present application. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments.

[0047] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components.

[0048] The term "and / or" in this application is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone.

[0049] In the embodiments of the present application, the same reference numerals represent the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width and other dimensions of various components in the embodiments of the present application shown in the drawings, as well as the overall thickness, length, width and other dimensions of the integrated device are only exemplary descriptions and should not constitute any limitation to the present application.

[0050] The term "plurality" used in the present application refers to two or more (including two).

[0051] During production and processing, the workpiece can be clamped by a fixture to facilitate the processing of the workpiece. The fixture can fix and position the workpiece.

[0052] Taking the workpiece as a battery cell as an example, the battery cell includes an end cap and a shell. The shell has an opening. When processing the battery cell, the end cap needs to be welded to the shell to close the opening of the shell to realize the assembly of the battery cell. When welding the end cap and the shell, the shell can be clamped by a fixture and welded by welding technology. The same battery cell model can be clamped by the same model of fixture to carry out batch assembly of battery cells of this model.

[0053] When the model of the battery cell needs to be changed, the clamp can be replaced to adjust the clamping distance of the clamp so that the clamping distance matches the size of the corresponding model of the battery cell. However, the clamp replacement process is relatively cumbersome, and multiple models of clamps need to be manufactured to match different models of battery cells. The production cost of the clamp is high, and the entire clamp replacement affects the adjustment efficiency of the clamp.

[0054] In order to improve the adjustment efficiency of the fixture when the workpiece is changed, an embodiment of the present application provides a fixture, which includes a base, a first clamping assembly and a second clamping member, the first clamping assembly includes a first connecting seat, a first clamping member and a first driving member, the first driving member connects the first clamping member and the first connecting seat, the first driving member is configured to drive the first clamping member to move along a first direction relative to the first connecting seat, and the first connecting seat is adjustably arranged on the base along the first direction; the second clamping member is arranged on the base and is arranged opposite to the first clamping member along the first direction, and the second clamping member and the first clamping member are used to cooperate in clamping the workpiece.

[0055] By adjustably setting the first connection seat on the base, the position of the first clamping assembly can be adjusted by adjusting the position of the first connection seat, thereby adjusting the minimum clamping distance between the first clamping member and the second clamping member. The workpiece can be changed without changing the clamp, thereby improving the adjustment efficiency of the clamp.

The second clamping member 20 can enter a fixed state by inserting the locking pin into the pin hole, or enter an active state by removing the locking pin from the pin hole.

[0065] The first driving member 3 drives the first clamping member 1 to move and can move the first clamping member 1 to an extreme position. When the first clamping member 1 is at the extreme position, the first clamping member 1 and the second clamping member 20 are closest to each other along the first direction X. At this time, the distance between the first clamping member 1 and the second clamping member 20 is the minimum clamping distance between the first clamping member 1 and the second clamping member 20. The first driving member 3 cannot drive the first clamping member 1 to continue to approach the second clamping member 20 and can only drive the first clamping member 1 away from the second clamping member 20.

The first connecting seat 2 can adjust its position on the base 200 along the first direction X, so that the first clamping assembly 10 as a whole can follow the first connecting seat 2 to adjust its position on the base 200 along the first direction X, thereby adjusting the minimum clamping distance between the first clamping member 1 and the second clamping member 20, and then timely adjusting the minimum clamping distance of the fixture 1000 to adapt to the size of the workpiece 2000. Such a structure realizes the change of the fixture 1000 to adapt to the workpiece 2000 only by adjusting the position of the first connecting seat 2 on the base 200 along the first direction X, thereby improving the adjustment efficiency of the fixture 1000.

[0069] In some embodiments, the first connecting seat 2 has a protrusion, and the base 200 is provided with multiple locking holes, which are arranged at intervals along the first direction X.

[0078] By providing the strip hole 21 in one of the first connection seat 2 and the base 200 and the first mounting hole 2001 in the other, the locking attachment 4 can pass through the strip hole 21 and cooperate with the first mounting hole 2001 to achieve the locking of the first connection seat 2 and the base 200. The part provided with the strip hole 21 can adjust its position along the first direction X relative to the part provided with the first mounting hole 2001, so that the first connection seat 2 can adjust its position on the base 200, making the position of the first connection seat 2 more flexible, so that the clamp 1000 can be applied to clamp more types of workpieces 2000, and improve the practicality of the clamp 1000.

[0082] In some embodiments, please refer to Figure 3 and Figure 4 , Figure 3 A schematic diagram of the structure of a first clamping assembly 10 provided in some embodiments of the present application; Figure 4 for Figure 3 The first clamping assembly 10 further includes a first guide unit 5, the first guide unit 5 connects the first clamping member 1 and the first connecting seat 2, and the first guide unit 5 is configured to guide the first clamping member 1 to move along the first direction X relative to the first connecting seat 2.

[0083] The number of the first guide units 5 can be one or more. The first guide unit 5 can be fixedly connected to the first clamping member 1, for example, the first guide unit 5 is welded to the first clamping member 1; the first guide unit 5 can also be detachably connected to the first clamping member 1, for example, the first guide unit 5 and the first clamping member 1 are connected by bolts. The first guide unit 5 can be connected to the surface of the first connecting seat 2, for example, the surface of the first connecting seat 2 is provided with a guide slide groove, and the first connecting seat 2 is slidably arranged in the guide slide groove; the first guide unit 5 can also be plugged into the first connecting seat 2, for example, the first connecting seat 2 is provided in the first plug-in groove, and the first guide unit 5 is slidably plugged into the first plug-in groove.

[0084] By setting a first guide unit 5 to connect the first clamping member 1 and the first connecting seat 2, the first guide unit 5 can guide the first clamping member 1 to move along the first direction X relative to the first connecting seat 2, so that the movement of the first clamping member 1 is more stable and the accuracy of the movement of the first clamping member 1 along the first direction X is improved.

[0085] In some embodiments, the first guide unit 5 includes a first guide shaft 51 and a first guide sleeve 52 , the first guide shaft 51 is connected to the first clamping member 1 , the first guide sleeve 52 is disposed on the first connecting seat 2 , and the first guide shaft 51 is slidably inserted into the first guide sleeve 52 .

[0087] By providing the first guide shaft 51 and the first guide sleeve 52 , the guiding of the first guide unit 5 is made more precise, thereby improving the stability of the first clamping member 1 moving along the first direction X and improving the moving precision of the first clamping member 1 .

[0088] In some embodiments, Figure 4 As shown, the first connecting seat 2 is further provided with a liquid injection hole, which is connected to the first guide unit 5 . The liquid injection hole is used to provide lubricant to the first guide unit 5 , and the lubricant may be lubricating oil.

[0089] In some embodiments, the first clamping assembly 10 also includes a first buffer member 6, which is disposed on the first connecting seat 2, one end of the first guide shaft 51 is connected to the first clamping member 1, and the other end of the first guide shaft 51 is provided with a first stop member 61, and the first stop member 61 is configured to abut against the first buffer member 6 when the first clamping member 1 approaches the second clamping member 20 along the first direction X.

[0090] The number of the first buffer member 6 may be one or more. The first buffer member 6 may be arranged on the side of the first connection seat 2 away from the first clamping member 1 along the first direction X, and the first buffer member 6 is arranged between the first clamping member 1 and the first stop member 61; or the first buffer member 6 may be arranged on the side of the first connection seat 2 close to the first clamping member 1 along the first direction X, and the first stop member 61 is located between the first clamping member 1 and the first connection seat 2, and between the first buffer member 6 and the first connection seat 2.

[0091] The first stopper 61 may be fixedly connected to the first guide shaft 51, for example, the first stopper 61 and the first guide shaft 51 are welded; or the first stopper 61 and the first guide shaft 51 may be detachably connected, for example, the first stopper 61 and the first guide shaft 51 are threadedly connected via bolts.

[0092] By providing the first buffer 6 and the first stopper 61 on the first guide shaft 51, the first buffer 6 and the first stopper 61 can cooperate to buffer the first clamp 1 to move toward the second clamp 20. In the process of the first clamp 1 moving toward the second clamp 20, the first stopper 61 contacts the first buffer 6, and the first buffer 6 slows down the first clamp 1 from moving toward the second clamp 20, thereby reducing the impact of the first clamp 1 on the workpiece 2000 between the first clamp 1 and the second clamp 20, and reducing the risk of the first clamp 1 impacting the workpiece 2000 and causing damage to the workpiece 2000.

[0093] In some embodiments, there are multiple first guide units 5 , and the multiple first guide units 5 are arranged at intervals along the second direction Y, and the second direction Y is perpendicular to the first direction X.

[0094] When the first direction X is the length direction of the fixture 1000, the second direction Y may be the width direction or the height direction of the fixture 1000; when the first direction X is the width direction of the fixture 1000, the second direction Y may be the length direction or the height direction of the fixture 1000; when the first direction X is the height direction of the fixture 1000, the second direction Y may be the length direction or the width direction of the fixture 1000.

[0095] By providing a plurality of first guide units 5 , the first guide units 5 guide the movement of the first clamping member 1 , thereby improving the stability of the first clamping member 1 moving along the first direction X, so that the movement of the first clamping member 1 is more precise and stable.

[0096] In some embodiments, there are two first guide units 5 , and along the second direction Y, the first driving member 3 is located between the two first guide units 5 .

[0097] As an example, Figure 3As shown, the first guide unit 5 is arranged at intervals along the second direction Y, and the first clamping assembly 10 includes two first buffer members 6, which are arranged at intervals along the second direction Y. The two first buffer members 6 are respectively connected to one end of the two first guide shafts 51 away from the first clamping member 1. When the first driving member 3 drives the first clamping member 1 to move toward the second clamping member 20, the first stopper 61 first contacts the first buffer member 6, and the first buffer member 6 can buffer the movement of the first stopper 61, thereby slowing down the first clamping member 1 from continuing to move toward the second clamping member 20, thereby reducing the impact of the first clamping member 1 on the workpiece 2000 between the first clamping member 1 and the second clamping member 20.

[0098] By setting two first guide units 5 and arranging the first driving member 3 between the two first guide units 5, the first driving member 3 drives the first clamping member 1 to move more stably, reducing the risk of damage to the first clamping member 1 due to unilateral guiding of the first driving member 3, and improving the stability of the first clamping member 1.

[0099] In some embodiments, the base 200 is provided with a slide groove 20021 , and the first connecting seat 2 can be slidably disposed in the slide groove 20021 .

[0101] In the embodiment in which the base 200 is provided with the strip-shaped hole 21 or the first mounting hole 2001 , the strip-shaped hole 21 or the first mounting hole 2001 is disposed in the slide groove 20021 of the mounting groove 2002 .

[0102] By setting the slide groove 20021, the slide groove 20021 can guide the movement of the first connecting seat 2, so as to facilitate the movement of the first connecting seat 2 on the base 200. The slide groove 20021 can guide the movement direction and orientation of the first connecting seat 2, thereby guiding the orientation of the first clamping member 1, and improving the matching accuracy between the first clamping member 1 and the second clamping member 20.

[0103] In some embodiments, the base 200 is provided with a limiting member 7, and the limiting member 7 is configured to limit the first connecting seat 2 from being separated from the sliding groove 20021 in a direction away from the second clamping member 20.

[0104] The number of the limiting member 7 can be one, and the limiting member 7 is arranged on the base 200 and located on the side of the first connecting seat 2 away from the first clamping member 1; the number of the limiting members 7 can also be multiple, and multiple limiting members 7 are arranged on the base 200 and located on the side of the first connecting seat 2 away from the first clamping member 1, and the multiple limiting members 7 are arranged at intervals along the second direction Y. When there are multiple limiting members 7, the multiple limiting members 7 can contact the first connecting seat 2 together to limit the position of the first connecting seat 2; or only a part of the limiting members 7 can contact the first connecting seat 2 to limit the position of the first connecting seat 2.

[0105] By setting the limiter 7, the limiter 7 can limit the position of the first connecting seat 2 in the slide groove 20021, reducing the risk of the first connecting seat 2 escaping from the slide groove 20021. The limiter 7 can also abut the first connecting seat 2, thereby limiting the position of the first clamping assembly 10, reducing the risk of the first clamping assembly 10 loosening and shifting when holding the workpiece 2000.

[0106] In some embodiments, the base 200 is provided with a second mounting hole 2003 extending along the first direction X, and the limiting member 7 is threadedly connected to the second mounting hole 2003 .

[0107] The number of the second mounting holes 2003 may be one or more. When there are more than one second mounting holes 2003 , one second mounting hole 2003 may be screwed to one stopper 7 , or multiple second mounting holes 2003 may be screwed to one stopper 7 .

[0108] By threading the limit member 7 and the second mounting hole 2003, the limit member 7 can adjust its position on the base 200 through the second mounting hole 2003, thereby adjusting the position of the limit member 7 to limit the first connecting seat 2. The limit member 7 can contact the first connecting seat 2, reducing the risk of the first connecting seat 2 moving along the first direction X away from the second clamping member 20.

[0109] In some embodiments, please refer to Figure 5 , Figure 5 The schematic diagram of the structure of the first clamping assembly 10 provided in some embodiments of the present application is as follows: There are multiple limiters 7, and the limiters 7 are arranged at intervals along the second direction Y.

[0110] As an example, Figure 5 As shown, there are two limit members 7 , the two limit members 7 are arranged at intervals along the second direction Y, and the limit members 7 extend along the first direction X.

[0111] By providing a plurality of limiting members 7 , the plurality of limiting members 7 can jointly limit the position of the first connecting socket 2 , thereby reducing the risk of limiting failure of the limiting members 7 due to damage to individual limiting members 7 .

[0112] In some embodiments, please refer to Figure 1 and Figure 2 The clamping mechanism 100 further includes a second clamping assembly 30 and a fourth clamping member 40. The second clamping assembly 30 includes a second connecting seat 302, a third clamping member 301 and a second driving member 303. The second connecting seat 302 is disposed on the base 200. The second driving member 303 connects the third clamping member 301 and the second connecting seat 302. The second driving member 303 is configured to drive the third clamping member 301 to move relative to the second connecting seat 302 along a second direction Y, and the second direction Y is perpendicular to the first direction X. The fourth clamping member 40 is disposed on the base 200 and is disposed opposite to the third clamping member 301 along the second direction Y. The fourth clamping member 40 and the third clamping member 301 are used to cooperate with each other to clamp the workpiece 2000.

[0113] The number of the second clamping assembly 30 can be one, and one second clamping assembly 30 and one fourth clamping member 40 are arranged along the second direction Y; the number of the second clamping assembly 30 can also be multiple, and one fourth clamping member 40 is correspondingly arranged for one second clamping assembly 30 along the second direction Y, and multiple second clamping assemblies 30 are arranged along the first direction X.

[0114] The second connection seat 302 may be adjustable in position on the base 200, or may be fixedly disposed on the base 200. The number of the second driving member 303 may be one, and one second driving member 303 drives the third clamping member 301 to move relative to the second connection seat 302 along the second direction Y; the number of the second driving members 303 may also be multiple, and multiple second driving members 303 drive the third clamping member 301 to move relative to the second connection seat 302 along the second direction Y. The third clamping member 301 may be detachably connected to the second driving member 303, for example, the third clamping member 301 and the second driving member 303 are threadedly connected by bolts; the third clamping member 301 may also be fixedly connected to the second driving member 303, for example, the third clamping member 301 and the second driving member 303 are welded.

[0115] The fourth clamping member 40 can be fixedly arranged on the base 200, for example, the fourth clamping member 40 is welded to the base 200; the fourth clamping member 40 can also be detachably connected to the base 200, for example, the fourth clamping member 40 and the base 200 are threadedly connected by bolts. One third clamping member 301 can cooperate with one fourth clamping member 40 to achieve the clamping of one workpiece 2000, or multiple third clamping members 301 can cooperate with the same fourth clamping member 40 to achieve the clamping of multiple workpieces 2000. In the embodiment where the clamping mechanism 100 includes a clamping group, the third clamping member 301 and the fourth clamping member 40 can be two clamping parts of the clamping group.

[0116] By setting the second driving member 303 to connect the third clamping member 301 and the second connecting seat 302, the second driving member 303 can drive the third clamping member 301 to move relative to the second connecting seat 302 along the second direction Y, so as to cooperate with the fourth clamping member 40 to clamp the workpiece 2000, thereby realizing that the first clamping member 1 and the second clamping member 20 clamp the workpiece 2000 along the first direction X, and the third clamping member 301 and the fourth clamping member 40 clamp the workpiece 2000 along the second direction Y, thereby limiting the position of the workpiece 2000 in the plane where the first direction X and the second direction Y are located, realizing the clamping and positioning of the workpiece 2000, facilitating the processing of the workpiece 2000, and improving the processing accuracy of the workpiece 2000.

[0117] In some embodiments, please refer to Figure 4-Figure 6 , Figure 6 A schematic diagram of the structure of the second clamping member 20 provided in some embodiments of the present application. The first clamping member 1 includes a first connecting portion 11 and a first clamping portion 12, the first connecting portion 11 is connected to the output end of the first driving member 3, and the first clamping portion 12 is movably disposed on the first connecting portion 11 along the second direction Y. The second clamping member 20 includes a second connecting portion 201 and a second clamping portion 202, the second connecting portion 201 is connected to the base 200, and the second clamping portion 202 is movably disposed on the second connecting portion 201 along the second direction Y, and the second clamping portion 202 and the first clamping portion 12 are used to cooperate in clamping the workpiece 2000.

[0118] As an example, Figure 4 As shown, a first slide rail 111 is disposed on a side of the first connecting portion 11 facing away from the first guide shaft 51, and the first slide rail 111 extends along the second direction Y. A first slide groove 121 is disposed on a side of the first clamping portion 12 facing the first guide shaft 51, and the first slide groove 121 is slidably matched with the first slide rail 111. Figure 5 As shown, the first clamping member 1 further includes a first elastic member 13, which extends along the second direction Y, and connects the first connecting portion 11 and the first clamping portion 12. The first elastic member 13 is configured to rebound when the second clamping assembly 30 is separated from the workpiece 2000, so that the first clamping portion 12 and the second clamping portion 202 move toward the second clamping assembly 30 along the second direction Y. Figure 6 As shown, a second slide rail 2011 is provided on a side of the second connection portion 201 facing the first connection portion 11, and the second slide rail 2011 extends along the second direction Y. A second slide groove 2021 is provided on a side of the second clamping portion 202 facing the second connection portion 201, and the second slide groove 2021 is slidably matched with the second slide rail 2011. When the third clamping member 301 abuts against the workpiece 2000 and moves along the second direction Y, the workpiece 2000 can drive the first clamping portion 12 and the second clamping portion 202 to move along the second direction Y.

[0119] By movably setting the first clamping part 12 on the first connecting part 11 along the second direction Y, and movably setting the second clamping part 202 on the second connecting part 201 along the second direction Y, after the first clamping part 12 and the second clamping part 202 clamp the workpiece 2000, the third clamping part 301 can abut the workpiece 2000 and move toward the fourth clamping part 40 during the process of clamping the workpiece 2000, so that the first clamping part 12 and the second clamping part 202 move toward the fourth clamping part 40 along the second direction Y, reducing the risk of the first clamping part 12 and the second clamping part 202 wearing the workpiece 2000.

[0120] In some embodiments, please refer to Figure 1 and Figure 2 The third clamping member 301 includes a third connecting portion 3011 and a third clamping portion 3012. The third connecting portion 3011 is connected to the output end of the second driving member 303. The third clamping portion 3012 is detachably connected to the third connecting portion 3011. The third clamping portion 3012 is used to extend into the gap between the first clamping member 1 and the second clamping member 20 to cooperate with the fourth clamping member 40 to clamp the workpiece 2000.

[0122] The third clamping portion 3012 can be detachably connected to the third connecting portion 3011 by snap connection, thread connection, fastener connection or other methods.

[0123] By connecting the third connection part 3011 to the second driving member 303 and the third connection part 3011 to the third clamping part 3012, the second driving member 303 can drive the third clamping part 3012 to move toward the fourth clamping part 402 to clamp the workpiece 2000.
