DETAILED DESCRIPTION

[0029] The utility model will be further explained in connection with the drawings and specific embodiments, but the protection scope of the utility model is not limited to this.

[0030] Embodiment:

[0031] As Figure 1 shown, the utility model relates to a kind of lithium battery module tool fixture, the utility model is horizontally placed on ground, and the first fixed component is equipped with fixed end 3, and can select several numbers of pile block 4 according to the size requirement of lithium battery module, and contact block 5 directly contacted with the end surface of lithium battery module is last.In the fixed direction of first fixed component, i.e. the other end in first fixed direction is sequentially provided with top block 2 and cylinder 1, and top block 2 is installed in the end of the working part of cylinder 1.Top block 2 and contact block 5 correspond.

[0032] Along the fixed direction of second fixed component, i.e. four side end fixing blocks 6 and two side end movable blocks 11 are respectively arranged in the two sides of fixed end 3 and cylinder 1 in second fixed direction, and side end fixing block 6 and side end movable block 11 also correspond.Side end fixing block 6 is adjustably installed on fixed positioning plate 7, and fixed positioning plate 7 is fixedly installed on bottom plate 9.Side end movable block 11 is adjustably installed on movable positioning plate 10, and movable positioning plate 10 is movably installed on movable part support plate 12 in small range in second fixed direction, and movable part support plate 12 is movably installed on bottom plate 9 along support plate slide rail 9.1.

[0033] Therefore, the utility model discloses can pass through the fixed stroke's cylinder 1 being equipped with in first fixed direction make lithium electricity module be fixed in first fixed direction, and through the movement of movable positioning plate 10 and movable part support plate 12, namely movable positioning plate 10 is in movable part support plate 12 on the push-pull assembly 12.1 control its in the slide rail 12.6 along the second fixed direction sliding of limited, movable part support plate 12 then through the handle 12.3 in the track range of support plate slide rail 9.1 on the bottom plate 9 along the second fixed direction sliding.

[0034] As Figure 1 And Figure 4 The component for limiting one end in the first fixed direction is fixed end 3, which is installed on the bottom plate 9, and its position is already limited and will not move or deviate due to the impact when the lithium battery module is fixed. After installing the contact block 5, the contact surface 5.2 of the contact block 5 and the top block 3 installed at the end of the working part of the cylinder 1 form an area, which is the maximum length of the lithium battery module that can be clamped by the first fixed module of the utility model.

[0035] The structure of the fixed end 3 is inverted T-shaped, with one end of the flat plate at the bottom being narrower as the narrow end and the other end being longer than the narrow end as the long end. The narrow end and the long end are separated by a vertical plate. On the side of the vertical plate close to the long end, a protrusion 3.1 is provided on the side of the vertical plate away from the long end, and an embedded block mounting hole 3.1.1 is provided on the protrusion 3.1 of the vertical plate perpendicular to the long end and the narrow end. Two rows of two columns of fixed end mounting holes 3.2 for installing the fixed end 3 on the bottom plate 9 are also provided on the long end. To enhance the impact resistance and bending strength of the fixed end 3, a rib is symmetrically provided between the vertical plate and the long end on the outside of the fixed end mounting hole 3.2. The rib can share the bending moment transmitted from the protrusion 3.1 to the vertical plate when the cylinder 1 fixes the lithium battery module in the first fixed direction, effectively reducing the bending deformation and other damage that may occur when the fixed end 3 limits the movement of the lithium battery module in the first fixed direction.

[0036] The rib between the long end and the vertical plate has a shorter contact portion with the vertical plate and a longer contact portion with the long end, so the portion of the vertical plate without the rib has poor bending strength and compression strength. Because the protrusion 3.1 needs to fix the lithium battery module in the first fixed direction, and the protrusion 3.1 is close to the end surface of the lithium battery module. Therefore, if the rib between the long end and the vertical plate is too long and has too large a size area, it may greatly limit the lithium battery module and other components for fixing the components that need to be installed on the fixed end 3, and may easily interfere with the fixing of the lithium battery module in the first fixed module, causing problems such as being unable to fix. Therefore, the area of the vertical plate in contact with the rib is small.

[0037] The ribs between the narrow end and the vertical plate are also symmetrically distributed on both sides of the narrow end and the vertical plate between the narrow end and the vertical plate. The length of the ribs on the narrow end is equivalent to the length of the narrow end, slightly less than the length of the narrow end. The height of the contact on the vertical plate is also equivalent to the height of the vertical plate, slightly less than the height of the vertical plate. By distributing the ribs in this way, the ribs can exert the bending strength and compressive strength of the fixing end 3 as much as possible, and can better withstand the impact load when fixing the lithium battery module in the first fixing direction.

[0038] The fixing end 3 needs to be designed with a narrow end and a long end at the bottom, and the narrow end and the long end are separated by a vertical plate. Because the protrusion 3.1 on the fixing end 3 can freely increase or decrease the stacking blocks 4 and the contact blocks 5 according to the length of the lithium battery module, the length of the protrusion 3.1 is indirectly increased by the extended stacking blocks 4 and contact blocks 5, thereby achieving the fixing of the lithium battery module with a shorter length in the first fixing direction.

[0039] Because the stacking blocks 4 and the contact blocks 5 are installed on the protrusion 3.1 of the fixing end 3, the center of gravity of the fixing end 3 as a whole will be offset. The protrusion 3.1 is provided at the long end to enable the center of gravity of the fixing end 3 after installation of the stacking blocks 4 and the contact blocks 5 to project within the plane of the long end. This enables the load on the fixing end 3 to be more evenly distributed, and the fixing end 3 has stronger impact resistance, compression resistance and bending resistance, better mechanical properties and a longer service life.

[0040] As shown in Figure 1 and Figure 3 and Figure 4 and Figure 5 The stacking blocks 4 and the contact blocks 5 are components for extending the length of the fixing end 3 in the first fixing direction and can be installed on the fixing end 3. As can be seen, the main body of the stacking block 4 is a cuboid, and on the two side end faces perpendicular to the first fixed module and parallel to the second fixed module, one side end face is provided with a recess 4.2 for installation with the fixing end 3, and the other side end face is provided with a protrusion 4.1 for installation with the contact block 5. The protrusion 4.1 and the recess 4.2 are located at the center position of the side end face of the stacking block 4, and the cross-sectional area of the protrusion 4.1 is the same as the cross-sectional area of the missing part of the recess 4.2, which means that the protrusion 4.1 of any stacking block 4 can be inserted with the recess 4.2 of any stacking block 4, similar to a mortise and tenon structure.

[0041] The recess 4.2 of the stacking block 4 can be mutually fitted with the protrusion 3.1 of the fixing end 3. The stacking block 4 and the contact block 5 have symmetric columnar protrusions on the narrow faces on both sides near the positions of the recess 4.2 and the fitting part 5.1 in the second fixing direction, which facilitates the disassembly of the stacking block 4 and the contact block 5.

[0042] As shown in Figure 3As shown, the cross-sectional shape of the stacking block 4 is a transversely placed convex shape. Above the recess 4.2 of the stacking block 4, near the deepest point of the recess 4.2, a recess fixing hole 4.3 is provided. On the protrusion 4.1 of the stacking block 4, near the outer end face of the protrusion 4.1, a protrusion fixing hole 4.4 is provided. The axis of the protrusion fixing hole 4.4 on the protrusion 4.1 of the stacking block 4 matches the axis of the recess fixing hole 4.3 on the recess 4.2 of the stacking block 4.

[0043] like Figure 4 As shown, the cross-sectional shape of the contact block 5 is a horizontal U-shape. A fixing hole 5.3 is vertically provided on the inner wall of the mating part 5.1 of the contact block 5 near the contact surface 5.2. The mating part 5.1 of the contact block 5 can not only be inserted into and fitted with the protrusion 4.1 on the stacking block 4, but also fit with the protrusion 3.1 on the fixing end 3.

[0044] like Figure 5 As shown, at this point, the protrusion 4.1 of the stacking block 4 is inserted into the mating part 5.1 of the contact block 5. It is clearly visible that the fixing hole 5.3 of the contact block 5 and the fixing hole 4.4 of the protrusion of the stacking block 4 are matched and have the same diameter. The mating of the fixing hole 5.3 and the fixing hole 4.4 after the contact block 5 and the stacking block 4 are fitted together is to facilitate threaded fixing of the two using screws. Because the mating of the protrusion 4.1 and the mating part 5.1 alone is insufficient, the protrusion 4.1 extending from the stacking block 4 is relatively short, and the mating depth is relatively small compared to the total height of the contact block 5. Furthermore, due to gravity, relative movement easily occurs between the stacking block 4 and the contact block 5, causing the mating part 5.1 of the contact block 5 and the protrusion 4.1 of the stacking block 4 to loosen. This causes the contact block 5 to loosen and slip off after installation with the stacking block 4.

[0045] Therefore, after the stacking block 4 and the contact block 5 are fitted together, the protrusion 4.1 of the stacking block 4 needs to be tightly locked into the fitting part 5.1 of the contact block 5 through the fixing hole 5.3 and the protrusion fixing hole 4.4, and the combined component of the contact block 5 and the stacking block 4 needs to be firmly fixed on the protrusion 3.1 of the fixing end 3. Only in this way can the contact block 5 and the stacking block 4 not fall off the fixing end 3 due to impact when the contact surface 5.2 of the contact block 5 is fixed in the first fixing direction with the cylinder 1.

[0046] and Figure 5The protrusions 4.1 and the fitting portions 5.1 are similar in shape and size, and the protrusions 3.1 of the fixed end 3 and the protrusions 4.1 are the same in shape and size, and the protrusions 3.1 are provided with the same fixing holes, i.e., the block mounting holes 3.1.1. Therefore, after the fitting portions 5.1 of the contact blocks 5 are fitted with the protrusions 3.1 of the fixed end 3, the contact blocks 5 can be fixed with the fixed end 3 by means of the fixing holes 5.3 and the block mounting holes 3.1.1.

[0047] The recesses 4.2 of the stacking blocks 4 and the fitting portions 5.1 of the contact blocks 5 are the same in shape and size, and therefore the stacking blocks 4 can be fitted with each other by means of the recesses 4.2 and the protrusions 4.1. Similarly, after the recess 4.2 of one stacking block 4 is fitted with the protrusion 4.1 of another stacking block 4, the two stacking blocks 4 can be fixed by means of the recess fixing holes 4.3 and the protrusion fixing holes 4.4.

[0048] The stacking blocks 4 and the fixed end 3 are fixed by means of the recesses 4.2 and the protrusions 3.1, and the recess fixing holes 4.3 and the block mounting holes 3.1.1.

[0049] Therefore, in the first fixed module, the number of the stacking blocks 4 and the contact blocks 5 can be freely selected according to the length of the lithium battery module, and because the shapes are matched with each other, the installation mode between every two components is plug-in and fixed by means of bolts, and therefore it is not easy to have gaps, and when the lithium battery module is fixed, a certain impact can be borne and the stability of the fixed end 3 can be maintained.

[0050] Correspondingly, the stacking blocks 4 cannot be infinitely installed on the fixed end 3. On the one hand, the installation of the stacking blocks 4 on the fixed end 3 forms a cantilever beam structure of the stacking block column composed of the stacking blocks 4, and when the length of the installation reaches a certain length, bending and a decrease in the impact resistance are inevitable, and secondly, the longer the length of the stacking block column, the more the center of gravity of the combined fixed part deviates from the face of the long end of the fixed end 3, which leads to instability of the structure of the fixed end 3, stress is concentrated in some corner positions, and the impact resistance of the whole fixed part is reduced. Therefore, the number of the stacking blocks 4 needs to be selected within a reasonable range when the lithium battery module is fixed in the first fixed module.

[0051] After the composition of the first fixed module and the fixing mode of the lithium battery module are described, the fixing mode and structure of the second fixed module of the lithium battery module will be described.

[0052] As shown in FIG. 6, the second fixed module is composed of a fixed end 3 and a plurality of contact blocks 5, and the fixed end 3 is provided with a plurality of protrusions 3.1, and the contact blocks 5 are provided with fitting portions 5.1. Figure 1As shown, in the second fixed module, the side-end fixing block 6 and the side-end movable block 11 can play a role in fixing the lithium battery module. The side-end fixing block 6 and the side-end movable block 11 are located on both sides of the first fixed module.

[0053] The side-end fixed block 6 and the side-end movable block 11 have the same shape and size. From the side, it can be seen that the side-end movable block 11 is L-shaped, and a rib is provided between its bottom plate and vertical plate to fix it.

[0054] The side-end fixing block 6 is mounted on the fixed positioning plate 7, which is directly fixed to the base plate 9, similar to the fixing end 3 of the first fixing module. At the beginning of the clamping process, after the side-end fixing block 6 is fixed to the fixed positioning plate 7, it is firmly fixed to the base plate 9 and no longer moves.

[0055] In this embodiment, four side-end fixing blocks 6 are installed on the fixed positioning plate 7. The fixed positioning plate 7 has a plurality of holes arranged in an array for installing the side-end fixing blocks 6, so the installation position of the side-end fixing blocks 6 on the fixed positioning plate 7 can be adjusted even when not clamped. Generally, after the four side-end fixing blocks 6 are installed on the fixed positioning plate 7, the line connecting them is parallel to the first fixing direction.

[0056] Opposite to the side-fixed block 6 in the second fixed direction is the side-movable block 11. During the clamping process, the side-movable block 11 is fixed to the movable positioning plate 10. The movable positioning plate 10, similar to the fixed positioning plate 7, has an array of mounting holes for installing the side-movable block 11. The two side-movable blocks 11 on the movable positioning plate 10 can also be freely adjusted in their mounting position when not clamped.

[0057] Unlike the fixed positioning plate 7, the bottom of the movable positioning plate 10 is equipped with a positioning plate slider 10.1 and a push rod 10.2, which allows the movable positioning plate 10 to move in a limited manner along the second fixed direction on the movable part support plate 12.

[0058] like Figure 6 As shown, a pair of slide rails 12.6 are provided at one end of the movable part support plate 12. Near the slide rails 12.6, a push-pull assembly 12.1 is provided between the two slide rails 12.6. A locking pin 12.2 is provided on the side of the movable part support plate 12 that is in the middle but far from the slide rails 12.6. A handle 12.3 is provided near the locking pin 12.2 and near the other end of the movable part support plate 12. A buffer block 12.4 is provided on one side of the handle, parallel to the movable part support plate 12.

[0059] exist Figure 1The bottom of the movable positioning plate 10 is provided with a positioning plate sliding block 10.1 which is matched with a sliding rail 12.6 provided on the movable part support plate 12, the positioning plate sliding block 10.1 is sleeved on the sliding rail 12.6, and the movable positioning plate 10 can slide on the movable part support plate 12. A push rod 10.2 is provided between the two positioning plate sliding blocks 10.1 of the movable positioning plate 10, one end of the push rod 10.2 is connected with a push-pull assembly 12.1 on the movable part support plate 12, and the sliding of the movable positioning plate 10 on the sliding rail 12.6 can be controlled through the push-pull assembly 12.1.

[0060] As shown in Figure 7 , the bottom of the movable part support plate 12 is provided with four sliding blocks 12.5, which are arranged in pairs on both sides of the movable part support plate 12, and each sliding block 12.5 is located at one foot of the movable part support plate 12. The sliding direction of the four sliding blocks 12.5 is parallel, and parallel to the second fixing direction.

[0061] As shown in Figure 8 , the bottom plate 9 is provided with two parallel support plate sliding rails 9.1 and a pin shaft clamping rail 9.2, the pin shaft clamping rail 9.2 is located between the two support plate sliding rails 9.1, and a part of the two support plate sliding rails 9.1 is located on the bottom plate 9, and the other part is suspended. The pin shaft clamping rail 9.2 is also the same, one part of the pin shaft clamping rail 9.2 is located on the bottom plate 9, and the other part is suspended.

[0062] The part of the support plate sliding rail 9.1 and the pin shaft clamping rail 9.2 located on the bottom plate 9 and the part suspended is because the installation position of the support plate sliding rail 9.1 and the pin shaft clamping rail 9.2 on the bottom plate 9 is far away, and the bottom plate 9 also needs to place the lithium battery module, but the support plate sliding rail 9.1 and the pin shaft clamping rail 9.2 place the movable part support plate 12. Increasing the area of the bottom plate 9 to make the support plate sliding rail 9.1 and the pin shaft clamping rail 9.2 completely located on the bottom plate 9 will cause a large area of material waste, so measures can be taken, such as using a cushion block or thickening the part of the support plate sliding rail 9.1 and the pin shaft clamping rail 9.2 located outside the bottom plate 9, so that the thickening thickness of this part is the same as the thickness of the bottom plate 9, which can directly contact the ground.

[0063] Therefore, the movable part support plate 12 is installed on the support plate sliding rail 9.1 of the bottom plate 9 through the sliding block 12.5, and the locking pin shaft 12.2 on the movable part support plate 12 can be inserted into the clamping hole of the pin shaft clamping rail 9.2 of the bottom plate 9, which is convenient for locking the movable part support plate 12 after moving to the appropriate position through the locking pin shaft 12.2, and further controlling the position of the side end movable block 11 through the push-pull assembly 12.1 on the movable part support plate 12. Finally, the lithium battery module is fixed on the second fixed module.

[0064] The utility model discloses a kind of lithium battery module tooling fixtures, how to clamp lithium battery module will be described in the working process.

[0065] Before starting to clamp lithium battery module, the length of the long side of lithium battery module is measured, and the length of lithium battery module is measured, and the length reserved for lithium battery module in the first fixed module is calculated in combination with the formation of air cylinder, according to the reserved length, a proper number of stacking blocks 4 are installed on the fixed end 3, and finally a contact block 5 is installed on the stacking block 4.

[0066] After the preparation work of the first fixed module is completed, according to the width of the lithium battery module and the side end face shape of the lithium battery module, the side end fixed block 6 in the second fixed module is installed on the fixed positioning plate 7 according to the side face shape and the width of the lithium battery module.

[0067] The installation position of the side end movable block 11 on the movable positioning plate 10 is adjusted according to the side end shape of the lithium battery module. After the preparation work is completed, the lithium battery module is placed on the bearing plate 8, wherein the longer side of the lithium battery module should be parallel to the first fixed direction. One end of the lithium battery module is placed on the fixed part composed of the fixed end 3, the stacking block 4 and the contact block 5, specifically on the contact surface 5.2 of the contact block 5, and the other side of the lithium battery module is in contact with the side end fixed block 6. Start the air cylinder 1, and the lithium battery module is fixed in the first fixed module.

[0068] Open the push-pull assembly 12.1, and move the movable positioning plate 10 to the farthest distance, i.e. the position farthest from the handle 12.3. Remove the locking pin 12.2 inserted in the pin shaft card rail 9.2, push the handle 12.3, and make the side end movable block 11 contact with the side surface of the lithium battery module. After the two are firmly contacted, the locking pin 12.2 is reinserted in the movable part support plate 12 and clamped in the corresponding hole of the pin shaft card rail 9.2. At this time, the lithium battery module is also fixed in the second fixed module.

[0069] When the processing of the lithium battery module is completed, first, close the air cylinder 1, release the lithium battery module from the first fixed module, then close the push-pull assembly 12.1, retract the movable positioning plate 10, separate the side end movable block 11 from the lithium battery module, remove the locking pin 12.2, and pull the handle 12.3 until the buffer block 12.4 hits the rear. At this time, the processing of the lithium battery module is completed, and the lithium battery module can be moved to the next process by other lifting devices.
