A battery usually includes a box and a plurality of battery cells arranged in the box. The box includes two end plates oppositely arranged along the direction in which the battery cells are arranged, and two opposite side plates perpendicular to the direction in which the battery cells are arranged. .

Figure 1 shows a schematic diagram of the working state of the centering adjustment device in an embodiment of the present application; Figure 2 shows a schematic structural diagram of the centering adjustment device in an embodiment of the present application.

Referring to FIGS. 1 and 2 , an embodiment of the present application provides a centering adjustment device for aligning the center lines of at least two workpieces 10 with a preset center line 11 . The centering adjustment device includes two sets of adjustment mechanisms 100 arranged on both sides of a preset center line 11. Each set of adjustment mechanisms 100 includes at least two adjustment components 110 spaced apart along the direction of the preset center line 11. Each adjustment component 110 It includes deformation parts 111; among them, the adjustment components 110 of the two sets of adjustment mechanisms 100 are arranged in pairs along the direction perpendicular to the preset center line 11.

Among them, the workpiece 10 includes battery cells, end plates and other components that need to be aligned and adjusted.

In the technical solution of the embodiment of the present application, two sets of adjustment mechanisms 100 are disposed on both sides of a preset center line 11. Each set of adjustment mechanisms 100 includes at least two adjustment components 110 spaced apart along the direction of the preset center line 11. Each adjustment component 110 includes a deformation member 111. In the two sets of adjustment mechanisms 100, the adjustment components 110 are arranged in pairs along the direction perpendicular to the preset center line 11. In each pair of adjustment components 110, two deformation members 111 are in contact with the workpiece 10 at the same time. Press so that the center line of the workpiece 10 is aligned with the preset center line 11. By pressing the two deformation members 111 on both sides of the preset centerline 11 against the workpiece 10 at the same time, the centerline of the workpiece 10 between the paired adjustment components 110 can be kept aligned with the preset centerline 11 . Based on this, by adjusting the center lines of the workpieces 10 between the multiple pairs of adjustment components 110 to align with the preset centerline 11 , the central alignment of the multiple workpieces 10 can be achieved, thus solving the problem of alignment caused by the large dimensional tolerance of the workpieces 10 difficult to adjust.

It can be understood that the preset center line 11 is a virtual line set to provide a centrally aligned reference line during the centering adjustment process. In order to facilitate operation and observation during the centering adjustment, the virtual line can also be drawn or carved. come out.

The two sets of adjustment mechanisms 100 of the centering adjustment device are disposed on both sides of the preset center line 11 , including two sets of adjustment mechanisms 100 equidistantly disposed on both sides of the preset center line 11 , and two sets of adjustment mechanisms 100 unequally spaced. The ground is arranged on both sides of the preset center line 11. When the two sets of adjustment mechanisms 100 are equally spaced on both sides of the preset center line 11 , in the two adjustment assemblies 110 arranged in pairs, the deformation member 111 moves in the direction perpendicular to the preset center line 11 under the pressure of the workpiece 10 The deformation amounts on The distance between the adjustment component 110 and the preset centerline 11 is D1, the distance between the second adjustment component 110 on the other side and the preset centerline 11 is D2, and the first deformation member 111 of the first adjustment component 110 The deformation amount of the second deformation component 111 of the second adjustment component 110 in the direction perpendicular to the preset center line 11 under the pressure of the workpiece 10 is L1. The amount of deformation is L2, D1-D2=L2-L1, thereby ensuring that the workpiece 10 is accurately adjusted and centered under the action of the deformation member 111.

In some embodiments, the centering adjustment device includes a driving mechanism 200 that is drivingly connected to each set of adjustment mechanisms 100 for applying a driving force toward the preset centerline 11 to the adjustment mechanism 100 . The driving mechanism 200 applies a driving force toward the preset center line 11 to the adjustment mechanism 100 , so that the center line of the workpiece 10 located between the paired adjustment components 110 can be adjusted to be aligned with the preset center line 11 .

Specifically, the driving mechanism 200 includes electric cylinders, and the number of electric cylinders located on the same side of the preset center line 11 may be one or more.

Furthermore, each set of adjustment mechanisms 100 includes a pressure plate 120 , and all adjustment components 110 are spaced apart on the pressure plate 120 along the direction of the preset center line 11 . The driving mechanism 200 is drivingly connected to the pressure plate 120 in each set of adjustment mechanisms 100 . By arranging the adjustment components 110 at intervals on the pressure plate 120 along the direction of the preset centerline 11, and drivingly connecting the driving mechanism 200 with the pressure plate 120, the pressure plate 120 is used to transmit the driving force exerted by the driving mechanism 200 to all the adjustment components 110 at the same time, thereby At the same time, the center lines of the multiple workpieces 10 are adjusted to be aligned with the preset center line 11 to achieve central alignment of the multiple workpieces 10 . The pressure plate 120 serves to connect multiple adjustment components 110 and transmit the driving force of the driving mechanism 200 to the multiple adjustment components 110. It may not have the ability to actively apply pressure to other components. The shape of the pressing plate 120 can be circular, elliptical, polygonal or a combination thereof. The length of the pressing plate 120 along the direction of the preset center line 11 is greater than or equal to the sum of the thicknesses of the multiple workpieces 10 in the arrangement direction that require centering adjustment.

In some embodiments, one end of the deformation member 111 in each adjustment assembly 110 is fixedly connected to the pressure plate 120 , and the other end extends in a direction away from the pressure plate 120 and has a certain deformation capability in a direction perpendicular to the preset centerline 11 . During the centering adjustment process, the two deformation members 111 in the same pair of adjustment components 110 are pressed against the workpiece 10 at the same time. Through the deformation of the deformation members 111 in the direction of the vertical preset center line 11, the workpiece 10 can be adjusted in the direction of the vertical preset center line. Based on this, by pre-setting the deformation ability of the deformation member 111 in the direction perpendicular to the preset center line 11, it is possible to control the position to which the workpiece 10 will be adjusted. Furthermore, in order to facilitate the fixation of the deformation member 111 and the pressure plate 120, a protrusion is provided on the side of the pressure plate 120 facing the preset center line 11, and one end of the deformation member 111 is fixed to the protrusion.

Specifically, the deformation member 111 includes a spring, and uses the compressed rebound force of the spring to adjust the position of the workpiece 10 . The structure is simple and does not cause damage to the workpiece 10 . Among them, spring materials include carbon spring steel (65 steel, 70 steel), low manganese spring steel (65Mn), silicon manganese spring steel (60Si2MnA).

It can be understood that the deformation ability of the deformation member 111 will affect the range of position adjustment of the workpiece 10. By presetting the deformation member 111 with a larger deformation ability range, the centering adjustment device can have a wider applicable range. Based on this, in some embodiments, the elastic modulus of the deformation member 111 is about 150N/mm2 to 300N/mm2. Optionally, the maximum compression amount of the deformation member 111 is about 5mm to 100mm, and the pressure range is about 100N to 500N. , making the centering adjustment device have a wider scope of application.

Specifically, the deformation ability of the deformation element 111 is affected by many factors. For example, when the specific form of the deformation element 111 is a spring, the wire diameter, outer diameter, and total number of turns of the spring will affect its deformation ability. By limiting the above parameters , can obtain the required deformation capability range. In some embodiments of the present application, the wire diameter of the spring is 1 mm to 3 mm, and the outer diameter is 5 mm. to 30mm, the total number of turns is 10 turns to 100 turns.

Referring to Figures 3, 4 and 5, in some embodiments, each adjustment assembly 110 includes an adjustment plate 112. The adjustment plate 112 is disposed at an end of the deformation member 111 facing away from the pressure plate 120 and can follow the pressure of the workpiece 10. The deformation member 111 moves relative to the pressure plate 120 . By arranging the adjustment plate 112 at one end of the deformation member 111 facing away from the pressure plate 120, and using the adjustment plate 112 to press against the workpiece 10, the process of adjusting the position of the workpiece 10 by the deformation member 111 is smoother. Among them, the adjustment plate 112 has a plate-like structure. In this embodiment, the adjustment plate 112 is between the deformation part 111 and the workpiece 10, instead of pressing the deformation part 111 against the workpiece 10, so as to obtain a larger contact area and make the deformation part The pressure provided by 111 is transmitted to the workpiece 10 more evenly. The shape of the adjustment plate 112 may be circular, polygonal or a combination thereof.

Further, the pressure plate 120 is provided with a sliding channel 121 extending in a direction perpendicular to the preset center line 11 . The adjustment assembly 110 includes a limiting rod 113 that slides through the sliding channel 121 . One end of the limiting rod 113 is connected to the adjusting plate 112 The other end is provided with a limiting section 113a. The limiting section 113a is used to limit the limiting rod 113 from being separated from the pressing plate 120 along its sliding direction. The deformation member 111 is sleeved on the limiting rod 113 and is located between the adjusting plate 112 and the pressing plate 120. The sliding channel 121 allows the limiting rod 113 to pass through and slide. The cross-sectional shapes of the sliding channel 121 and the limiting rod 113 may be circular, polygonal, or a combination thereof. Preferably, the cross-sectional shapes of the sliding channel 121 and the limiting rod 113 are circular, and their radial dimensions are the same, so that the sliding process of the limiting rod 113 is smoother.

When the limiting rod 113 receives a force along the direction of the vertical preset center line 11 , the limiting rod 113 will move along the direction of the vertical preset center line 11 , and because one end of the limiting rod 113 is connected to the adjustment plate 112 , the other end is provided with a limiting section 113a, so that the limiting rod 113 will not escape from the sliding channel 121. Based on this, when the driving mechanism 200 drives the pressure plate 120 to move toward the preset centerline 11 and presses the deformation member 111 against the workpiece 10 , the deformation member 111 is compressed because the deformation member 111 is sleeved on the limiting rod 113 and located Between the adjustment plate 112 and the pressure plate 120, the limit rod 113 can play a guiding and limiting role when the deformation member 111 is compressed, so that the deformation member 111 can smoothly deform in the direction perpendicular to the preset center line 11. Thereby, the center line of the workpiece 10 is adjusted to be aligned with the preset center line 11 more accurately.

Further, one end of the sliding channel 121 close to the preset centerline 11 is provided with a threaded section, and the adjustment assembly 110 includes an adjusting nut 114 that matches the threaded section. The adjusting nut 114 is sleeved on the limiting rod 113 , and the adjusting nut 114 faces the preset center. One end of the wire 11 is in contact with the deformation member 111 . By installing the adjusting nut 114 outside the limiting rod 113, one end of the adjusting nut 114 is threadedly connected to the threaded section of the sliding channel 121, and the other end of the adjusting nut 114 is in contact with the deformation member 111. By adjusting the adjusting nut 114, the sliding The depth of screwing into the channel 121 can adjust the movable range of the limit rod 113, so that in the initial state of the centering adjustment, the initial length of the deformation member 111 is adjustable, thereby satisfying the centering adjustment of the workpiece 10 of different sizes. need.

Specifically, the adjusting nut 114 includes a connected connecting section 114a and an abutting section 114b. The connecting section 114a is threaded with the threaded section to connect the adjusting nut 114 in the sliding channel 121. The abutting section 114b is connected to the deformation member. 111 abutting, and the radial size of the abutting segment 114b is larger than the radial size of the thread segment. When the connecting end is threaded with the threaded segment, since the radial size of the abutting segment 114b is larger than the radial size of the threaded segment, the abutting segment 114b can be prevented from entering the sliding channel 121, thereby ensuring that the abutting segment 114b can interact with the deformation member. 111 contact.

In some embodiments, the centering adjustment device further includes a bearing base 300 , and the adjustment mechanism 100 is disposed on the bearing base 300 . The adjustment mechanism 100 is arranged on the bearing seat 300 so that multiple workpieces 10 can be placed on the bearing seat 300 during the centering adjustment process, thereby ensuring that the heights of the multiple workpieces 10 can be kept consistent during centering adjustment. . Specifically, the adjustment mechanism 100 is fixed on the bearing base 300, or the adjustment mechanism 100 is placed on the bearing base.

Referring to Figure 1, in a specific embodiment, the centering adjustment device includes a bearing base 300, an electric cylinder provided on the bearing base 300, and two sets of adjustment components 110 provided on the bearing base 300. The two sets of adjustment components 110 are provided respectively. On both sides of a preset centerline 11, each set of adjustment mechanisms 100 includes a pressure plate 120 and a plurality of adjustment components 110. The driving end of the electric cylinder is connected to the pressure plate 120. The plurality of adjustment components 110 of each set of adjustment mechanisms 100 are along the preset The center line 11 is arranged at intervals on the pressure plate 120. In the direction perpendicular to the preset center line 11, the adjustment components 110 are arranged in pairs. Each adjustment component 110 includes a spring. One end of the spring is connected to the pressure plate 120, and the other end faces away. The direction of the pressure plate 120 extends. When multiple workpieces 10 are placed on the bearing seat 300 and between the two sets of adjustment components 110, the electric cylinder drives the pressure plate 120 to move toward the preset center line 11, thereby driving the spring to press against the workpieces 10, and the pressure plates on both sides are used. The spring presses against the workpiece 10 at the same time, so that the center line of the workpiece 10 is aligned with the preset center line 11 .
