[0036] like Figure 1 and Figure 2 As shown, the utility model provides an auxiliary pressing tool, which includes:

[0037] The lower pressing plate 1 is used to be arranged below the multiple layers of plates to be pressed 31, and each layer of plates to be pressed 31 is provided with a corresponding piece to be pressed 32 above it, and the pieces to be pressed 32 corresponding to the plates to be pressed 31 of each layer below the uppermost layer of the plates to be pressed 31 are exposed to the uppermost layer of the plates to be pressed 31;

[0038] An upper pressing plate 2, on which a plurality of pressing portions 21 are disposed, wherein the plurality of pressing portions 21 are disposed corresponding to the parts to be pressed 32 respectively;

[0039] The connecting structure is connected to the upper pressing plate 2 and the lower pressing plate 1 respectively, so as to press each to-be-pressed piece 32 onto the corresponding to-be-pressed plate 31 .

[0040] In this specification, the content of the utility model will be explained by taking the part 32 to be pressed as the copper block of the capacitor pool busbar, the plate 31 to be pressed as the copper plate of the capacitor pool busbar, and the number of the plates 31 to be pressed as three as an example, but it should be understood that it is not limited to this. The auxiliary pressing tool of the utility model can be used in other occasions where it is necessary to press multiple components to be pressed (the components to be pressed include the plate 31 to be pressed and the part 32 to be pressed corresponding to the plate 31 to be pressed).

[0041] In this specification, the three plates to be pressed 31 are defined as the first plate to be pressed 31a, the second plate to be pressed 31b and the third plate to be pressed 31c from top to bottom, and the piece to be pressed 32 corresponding to the first plate to be pressed 31a is defined as the first piece to be pressed 32a, the pressing portion 21 corresponding to the first piece to be pressed 32a is defined as the first pressing portion 21a, the piece to be pressed 32 corresponding to the second plate to be pressed 31b is the second piece to be pressed 32b, the pressing portion 21 corresponding to the second plate to be pressed 31b is the second pressing portion 21b, the piece to be pressed 32 corresponding to the third plate to be pressed 31c is the third piece to be pressed 32c, and the pressing portion 21 corresponding to the third plate to be pressed 31c is the third pressing portion 21c.

[0042] Specifically, the topmost plate 31 to be compressed is the first plate 31a to be compressed, and the plates 31 to be compressed in each layer below the topmost plate 31 to be compressed specifically include the second plate 31b to be compressed and the third plate 31c to be compressed. When the first plate 31a to be compressed, the second plate 31b to be compressed and the third plate 31c to be compressed are stacked, the second piece 32b to be compressed corresponding to the second plate 31b to be compressed and the third piece 32c to be compressed corresponding to the third plate 31c to be compressed are both exposed from the first plate 31a to be compressed. At this time, the first plate 31a to be compressed is provided with a first avoidance hole for exposing the second piece 32b to be compressed, and the first plate 31a to be compressed and the second plate 31b to be compressed are both provided with a second avoidance hole for exposing the third piece 32c to be compressed. Here, "exposed" should be understood as being able to operate the corresponding part to be compressed 32, for example, the second part to be compressed 32b can be operated through the first avoidance hole, which will be explained later in conjunction with specific embodiments.

[0043] In this embodiment, multiple layers of the plates to be pressed 31 can be placed on the lower pressing plate 1 and supported on the lower pressing plate 1, and the corresponding parts to be pressed 32 of the plates to be pressed 31 of each layer below the plate to be pressed 31 of the lowest layer are exposed to the plate to be pressed 31 of the highest layer. For example, the second part to be pressed 32b corresponding to the second plate to be pressed 31b of the second layer is exposed to the first plate to be pressed 31a through the first avoidance hole set for the second part to be pressed 32b of the first plate to be pressed 31a of the highest layer (i.e., the first layer), and the third part to be pressed 32c corresponding to the third plate to be pressed 31c of the third layer is exposed to the first plate to be pressed 31a through the first avoidance hole set for the second part to be pressed 32b of the first plate to be pressed 31c of the highest layer (i.e., the first layer). The second avoidance holes provided on the plate to be pressed 31a and the second plate to be pressed 31b corresponding to the third piece to be pressed 32c are exposed on the first plate to be pressed 31a, and a plurality of pressing parts 21 are provided on the upper pressing plate 2, and the positions of the plurality of pressing parts 21 correspond to the positions of the pieces to be pressed 32, so that when the connection structure is connected to the upper pressing plate 2 and the lower pressing plate 1, respectively, the plurality of pressing parts 21 contact the plurality of pieces to be pressed 32, respectively, and press the pieces to be pressed 32 on the corresponding plate to be pressed 31, thereby realizing the pressing operation of the plurality of plates to be pressed 31 and the corresponding pieces to be pressed 32. When the plate to be pressed 31 is a copper plate of the busbar of the capacitor cell, and the piece to be pressed 32 is a copper block, the pressing operation before welding of the plurality of copper plates and the corresponding copper blocks can be performed simultaneously, so that the welding operation of the plurality of copper plates and the corresponding copper blocks can be performed simultaneously, with high welding efficiency and strong practicality.

[0044] like Figure 1 and Figure 2 As shown, the position of the first surface S1 of each part to be pressed 32 in the up-down direction is higher than the position of the second surface S2 of the topmost plate to be pressed 31 in the up-down direction, and the part to be pressed 32 contacts the corresponding pressing part 21 through the first surface S1, and the second surface S2 of the topmost plate to be pressed 31 is arranged opposite to the upper pressing plate 2.

[0045] That is, the first surface S1 of the piece to be pressed 32 is its top surface, and the second surface S2 of the uppermost plate to be pressed 31 is the top surface of the first plate to be pressed 31 a.

[0046] When the connection structure is connected to the upper pressing plate 2 and the lower pressing plate 1 respectively, the third surface S3 (i.e., the lower surface) of the first pressing portion 21a contacts the first surface S1 of the first piece to be pressed 32a; the second piece to be pressed 32b passes through the second avoidance hole, and its first surface S1 is higher than the second surface S2 of the first plate 31a to be pressed in the vertical direction, and the third surface S3 of the second pressing portion 21b contacts the first surface S1 of the second piece to be pressed 32b; the third piece to be pressed 32c passes through the second avoidance hole, and the first surface S1 of the third piece to be pressed 32c is higher than the second surface S2 of the first plate 31a to be pressed in the vertical direction, and the third surface S3 of the third pressing portion 21c contacts the first surface S1 of the third piece to be pressed 32c. The positions of the third surface S3 of the first pressing portion 21a, the third surface S3 of the second pressing portion 21b, and the third surface S3 of the third pressing portion 21c in the vertical direction are determined according to the requirements of contacting the corresponding piece 32 to be pressed.

[0047] This situation will be used as an example to explain below, but it should be understood that, in some cases, the first surface S1 of the second part to be compressed 32b may be lower than the second surface S2 of the first plate to be compressed 31a and exposed to the first plate to be compressed 31a through the first avoidance hole. At this time, the second pressing portion 21b corresponding to the second part to be compressed 32b extends into the first avoidance hole and contacts the second part to be compressed 32b. The first surface S1 of the third part to be compressed 32c may be lower than the second surface S2 of the first plate to be compressed 31a and exposed to the first plate to be compressed 31a through the second avoidance hole. At this time, the third pressing portion 21c corresponding to the third part to be compressed 32c extends into the second avoidance hole and contacts the third part to be compressed 32c.

[0048] In this embodiment, the height requirement of each pressing portion 21 in the up-down direction can be reduced, so that each pressing portion 21 can be conveniently contacted with the corresponding piece 32 to be pressed and press the corresponding piece 32 to be pressed.

[0049] like Figure 2 As shown, optionally, the pressing part 21 is fixedly arranged on the upper pressing plate 2. In this way, the pressing force applied by the pressing part 21 is reliable, the structure is simple, and the practicability is strong.

[0050] like Figure 2 As shown, optionally, the pressing portion 21 includes a third surface S3, and contacts the corresponding to-be-pressed member 32 through the third surface S3, and the upper pressing plate 2 includes a fourth surface S4 arranged opposite to the lower pressing plate 1;

[0051] The third surface S3 of at least one pressing portion 21 is flush with the fourth surface S4 of the upper pressing plate 2 in the vertical direction, and / or the third surface S3 of at least one pressing portion 21 is lower than the fourth surface S4 of the upper pressing plate 2 in the vertical direction.

[0052] like Figures 1 to 5 As shown, the third surface S3 of the first clamping portion 21a corresponding to the first piece to be clamped 32a and the third surface S3 of the second clamping portion 21b corresponding to the second piece to be clamped 32b are both lower than the fourth surface S4 of the upper pressing plate 2, and the third surface S3 of the third clamping portion 21c corresponding to the third piece to be clamped 32c is flush with the fourth surface S4 of the upper pressing plate 2.

[0053] In this way, the structural arrangement of the pressing part 21 on the upper pressing plate 2 is facilitated, and the structure is simple.

[0054] Optionally, the sum of the first distance and the second distance corresponding to each part 32 to be pressed is equal, the first distance is the distance between the first surface S1 of the part 32 to be pressed and the second surface S2 of the topmost plate 31 to be pressed, and the second distance is the distance between the third surface S3 of the pressing part 21 corresponding to the part 32 to be pressed and the fourth surface S4 of the upper pressing plate 2.

[0055] Exemplarily, the first distance corresponding to the first piece to be pressed 32a is the distance between the first surface S1 of the first piece to be pressed 32a and the second surface S2 of the first plate to be pressed 31a, and the second distance corresponding to the first piece to be pressed 32a is the distance between the third surface S3 of the second pressing portion 21b and the fourth surface S4 of the upper pressing plate 2. The sum of the first distance and the second distance is ideally the distance between the fourth surface S4 of the upper pressing plate 2 and the second surface S2 of the first plate to be pressed 31a, and this distance is the set value.

[0056] In this embodiment, the sum of the first distance and the second distance corresponding to each part 32 to be pressed is equal, so that when the connecting structure is respectively connected to the upper pressing plate 2 and the lower pressing plate 1, it can ensure that each clamping part 21 is in contact with each part 32 to be pressed, and the corresponding part 32 to be pressed is pressed with the corresponding plate 31 to be pressed, and the pressing force to which each part 32 to be pressed is subjected tends to be consistent.

[0057] Optionally, the pressing portion 21 is integrally formed on the upper pressing plate 2 .

[0058] In this way, the structure of the pressing portion 21 is easily formed, the structure is simple, and the practicability is strong.

[0059] In some other schemes, the clamping portion 21 can be movably arranged on the upper pressure plate 2 along the up and down directions. In this case, a return spring can be arranged between the clamping portion 21 and the upper pressure plate 2, which is not shown in the figure of this scheme and will not be described in detail here.

[0060] Optionally, a support portion 11 is provided on the lower pressing plate 1 corresponding to each to-be-pressed plate 31 , and the position of the support portion 11 corresponds to the position of the to-be-pressed piece 32 on the to-be-pressed plate 31 .

[0061] Optionally, at least one layer of plates 31 to be pressed above the bottommost layer of plates 31 to be pressed is a setting plate, and the supporting portion 11 corresponding to the setting plate is a supporting platform, which passes through the layers of plates 31 to be pressed below the setting plate and abuts against the setting plate.

[0062] Exemplarily, the lower pressing plate 1 is provided with a first support portion 11a, a second support portion 11b and a third support portion 11c, which are respectively provided corresponding to the first piece to be pressed 32a, the second piece to be pressed 32b and the third piece to be pressed 32c. The first support portion 11a and the second support portion 11b are both support platforms, and the third support portion 11c is flush with the top surface of the lower pressing plate 1.

[0063] In this way, each plate 31 to be clamped can obtain reliable support at the part to be clamped 32, and the supporting force applied to each plate 31 to be clamped can be consistent, with high force reliability, which is beneficial to ensuring the tolerance of the clamping of the part to be clamped 32 and the plate 31 to be clamped, such as ensuring the quality of welding of copper plates and copper blocks.

[0064] It should be understood that the third support portion 11c may also be configured as a support platform, which is not a limitation and will not be described in detail herein.

[0065] Optionally, the support platform is integrally formed on the lower pressing plate 1 .

[0066] In this way, the manufacturing and forming of the support platform is facilitated, and each support platform has a unified positioning and processing reference, which is conducive to ensuring the dimensional accuracy of the support platform.

[0067] like Figures 1 to 5 As shown, optionally, the connection structure includes a threaded connector 4 and a nut structure 5 , and the threaded connector 4 is passed through the upper pressing plate 2 and the lower pressing plate 1 and is threadedly connected to the nut structure 5 .

[0068] In this way, force can be applied in the up and down directions by tightening the threaded connector 4 , so that the member to be pressed 32 and the plate to be pressed 31 are pressed together through the upper pressing plate 2 and the lower pressing plate 1 .

[0069] Of course, in other embodiments, the connection structure may also include a snap-on connection structure, through which the upper pressure plate 2 and the lower pressure plate 1 are connected, for example, the snap-on member passes through the upper pressure plate 2 and the lower pressure plate 1 and snaps onto the upper pressure plate 2 and the lower pressure plate 1 respectively.

[0070] It should be understood that the nut structure 5 can be provided on the lower pressing plate 1 , for example, the nut structure 5 is integrally formed on the lower pressing plate 1 .

[0071] The nut structure 5 can be arranged on a component below the lower pressing plate 1 . Optionally, it also includes a base 6 . The base 6 is located below the lower pressing plate 1 , and the nut structure 5 is arranged on the base 6 .

[0072] In this way, there is no need to use the lower pressing plate 1 to form the nut structure 5, and the service life of the lower pressing plate 1 is increased.

[0073] The nut structure 5 can be integrally or detachably arranged on the base 6. For example, the nut structure 5 is embedded in the base 6.

[0074] like Figure 1 , Figure 4 and Figure 5 As shown, optionally, the base 6 includes a seat body 61 and a seat plate 62, the seat plate 62 is located above the seat body 61, a first through hole 621 is provided on the seat plate 62, the nut structure 5 is embedded in the first through hole 621, and the seat plate 62 is detachably connected to the seat body 61.

[0075] In this way, there is no need to set the nut structure 5 on the lower pressure plate 1, and the nut structure 5 is easy to replace. After the thread of the nut structure 5 is stripped, the seat plate 62 can be removed and the nut structure 5 thereon can be removed.

[0076] Optionally, the seat body 61 is provided with an embedding groove 612 , and the embedding groove 612 is at least used to accommodate the seat plate 62 and the seat plate 62 in the lower pressing plate 1 .

[0077] For example, the embedding groove 612 is only used to accommodate the seat plate 62 . For example, the embedding groove 612 is used to accommodate the seat plate 62 and to accommodate the lower end of the lower pressing plate 1 .

[0078] Therefore, at least the seat plate 62 of the seat plate 62 and the lower pressing plate 1 can be positioned through the embedding groove 612, which has a simple structure and strong practicality.

[0079] Optionally, a second through hole 611 is provided on the seat body 61 , the position of the second through hole 611 corresponds to the position of the first through hole 621 , the aperture of the second through hole 611 is smaller than the aperture of the first through hole 621 , and the aperture of the second through hole 611 is larger than the inner diameter of the nut structure 5 .

[0080] In this way, the second through hole 611 can be used for the passage of the ejector rod to eject the nut structure 5 .

[0081] In the above embodiment, optionally, at least one of the parts to be compressed 32 is correspondingly provided with a threaded connection member 4 , and the threaded connection member 4 is penetrated through the corresponding part to be compressed 32 and the plate to be compressed 31 .

[0082] For example, each to-be-pressed member 32 is correspondingly provided with a threaded connector 4, so that the to-be-pressed member 32 can be pressed well.

[0083] like Figure 5As shown, in the above embodiment, optionally, a positioning pin 7 is also included, a first positioning hole 12 is provided on the lower pressure plate 1, the positioning pin 7 is inserted in the first positioning hole 12, the positioning pin 7 is used to connect with the second positioning hole 311 on the plate to be clamped 31, and the positioning pin 7 is also used to connect with the third positioning hole 321 on the part to be clamped 32.
