Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] As Figures 1-8As shown in the figure, a tooling fixture for a new energy battery pack housing includes a workbench 1, on which a number of mounting seats 11 and a crossbeam 12 are installed. The crossbeam 12 is installed at the upper ends of the mounting seats 11. A number of working cavities 10 are formed between the mounting seats 11 and the crossbeam 12. In this application, there are four mounting seats 11, so the number of working cavities 10 is three. Bottom support seats 51 are installed at the bottoms of the working cavities 10. In this application, the number of bottom support seats 51 is two. Back support blocks 52 for limiting the back of the battery pack housing are installed at the upper ends of the bottom support seats 51. A first ejector rod assembly 3 for limiting the upper end of the battery pack housing is provided at the bottom of the crossbeam 12. A second ejector rod assembly 4 for limiting the lower end of the battery pack housing is provided at the upper end of the workbench 1. A first front positioning member 100 for limiting the front end of the battery pack housing is also provided on the workbench 1. A second front positioning member 7 for limiting the front end of the battery pack housing is provided on the crossbeam 12. A back positioning member 8 for limiting the back of the battery pack housing is provided on the crossbeam 12. Side positioning members 9 are provided on the side walls of the working cavities 10.

[0030] It should be noted that: The battery pack housing in this application includes two models, which are referred to as the first housing 21 and the second housing 22 hereinafter. The first housing 21 is a cuboid cavity structure, and the second housing 22 is a right trapezoid cavity structure.

[0031] In this application, there are two groups of the first ejector rod assemblies 3. Each first ejector rod assembly 3 includes a first ejector rod 32 and a first cylinder 31. The first cylinder 31 is arranged on the crossbeam 12. The first ejector rod 32 reciprocates in the vertical direction through the first cylinder 31.

[0032] The second ejector rod assembly 4 includes a second ejector rod 42 and a second cylinder 41. The second cylinder 41 is arranged on the workbench 1. The second ejector rod 42 reciprocates in the vertical direction through the second cylinder 41.

[0033] The first front positioning member 100 includes a first positioning assembly 5 and a second positioning assembly 6. The first positioning assembly 5 and the second positioning assembly 6 are located on the left and right sides of the battery pack housing. The first positioning assembly 5 includes a first rotating cylinder 53 installed in the support seat. The first rotating cylinder 53 is drivingly installed with a first rotating arm 54. A first pressing block 55 for pressing against the battery pack housing is installed on the first rotating arm 54. A first abutting block 56 for abutting against the front end of the battery pack housing is provided on the first pressing block 55. The first abutting block 56 is adjustably installed on the first pressing block 55. In this application, the first abutting block 56 is an adjusting bolt. The distance from the end of the adjusting bolt to the battery pack housing is adjusted by the threaded fit between the adjusting bolt and the first pressing block 55, so that the first abutting block 56 abuts against the battery pack housing, thereby realizing the function of fixing the lower part of the front end of the battery pack housing.

[0034] The second positioning assembly 6 includes a second rotating cylinder 61 installed in the support seat. The second rotating cylinder 61 is drivingly installed with a second rotating arm 62. A second pressing block 63 for pressing against the battery pack housing is installed on the second rotating arm 62. The second pressing block 63 is arranged at an angle with the second rotating arm 62, so that the second pressing block 63 can abut against the hypotenuse of the second housing 22.

[0035] A stop block 64 is provided on the second pressing block 63. An inclined surface 65 for cooperating with the hypotenuse of the second housing 22 is provided on the stop block 64. In this application, there are two stop blocks 64, which are symmetrically arranged on the second pressing block 63. The stop block 64 abuts against the side of the battery pack housing, and the second pressing block 63 can also abut against the front end face of the first housing 21. Thus, the second pressing block 63 can limit and fix the front end face of the first housing 21 or the second housing 22.

[0036] The second front positioning member 7 includes a third rotating cylinder 71 installed on the cross beam 12. The third rotating cylinder 71 is drivingly installed with a third rotating arm 72. A third pressing block 73 for pressing against the battery pack housing is installed on the third rotating arm 72. A second abutting block 74 for abutting against the front end of the battery pack housing is provided on the third pressing block 73. In this application, the second abutting block 74 is an adjusting bolt. The distance from the end of the adjusting bolt to the battery pack housing is adjusted by the threaded fit between the adjusting bolt and the third pressing block 73, so that the second abutting block 74 abuts against the battery pack housing, thereby realizing the function of fixing the upper part of the front end of the battery pack housing.

[0037] It should be noted that: while the first rotating cylinder 53, the second rotating cylinder 61 and the third rotating cylinder 71 are rotating, axial movement will occur, so that it can be ensured that the first abutting block 56, the second abutting block 74 and the stop block 64 can abut against the battery pack housing after rotation.

[0038] In addition, the first rotating arm 54, the second rotating arm 62, and the third rotating arm 72 are all parallel to the upper end surface of the workbench 1 in the initial state, and are all perpendicular to the upper end surface of the workbench 1 in the working state.

[0039] The back positioning member 8 includes a fixing frame 81 and a contact rod 82 mounted on the fixing frame 81. The contact rod 82 is in contact and cooperation with the back of the battery pack housing. And the contact rod 82 is also a bolt in this application. By adjusting the distance from the end of the contact rod 82 to the battery pack housing, the back of the battery pack housing can be positioned. And the back of the battery pack housing is supported and limited by the contact rod 82 and the back support block 52 at the same time, which can make the battery pack housing more stable during the processing.

[0040] The side positioning member 9 includes a third positioning assembly 901. The third positioning assembly 901 includes a positioning seat 95 mounted on the side wall of the working cavity 10 and a positioning rod 96 mounted on the positioning seat 95. The positioning rod 96 is used to insert into the rear side wall of the cavity of the battery pack housing, and the positioning seat 95 is used to limit the left end wall of the battery pack housing. The battery pack housing is made more stable during the processing through multi-point positioning.

[0041] The side positioning member 9 further includes a fourth positioning assembly 902. The fourth positioning assembly 902 includes a third air cylinder 91 mounted on the other side wall of the working cavity 10. A connecting head 92 is mounted on the output of the third air cylinder 91. A fitting block 93 is mounted on the connecting head 92. A fitting groove 94 for cooperating with the battery pack housing is provided on the fitting block 93. The fourth positioning member is used to fix the first housing 21, and the fitting block 93 is hinged to the connecting head 92. Therefore, when the third air cylinder 91 extends and the fitting block 93 abuts against the first housing 21, it can swing. Therefore, when there is a certain error in the first housing 21, the first housing 21 can also be clamped into the fitting groove 94.

[0042] When machining the first housing 21: First, place the first housing 21 on the upper end of the bottom support base 51, and insert the positioning rod 96 into the cavity of the first housing 21. The positioning rod 96 is in abutting cooperation with the rear wall of the cavity inside the first housing 21. Additionally, make the left end of the first housing 21 in abutting cooperation with the positioning seat 95. Then, by pushing the first housing 21 backward, make the back of the first housing 21 in abutting cooperation with the back support block 52 and the abutting rod 82. At this time, start the first cylinder 31 and the second cylinder 41, and then make the first ejector rod 32 and the second ejector rod 42 move toward the first housing 21 until the first ejector rod 32 and the second ejector rod 42 are in abutting cooperation with the first housing 21. Further, start the first rotary cylinder 53, the second rotary cylinder 61, and the third rotary cylinder 71 to switch the first rotary arm 54, the second rotary arm 62, and the third rotary arm 72 to the working state. Thus, make the first abutting block 56, the second abutting block 74, and the stop block 64 in abutting cooperation with the front end of the first housing 21. Finally, start the third cylinder 91 to make the connecting head 92 move toward the first housing 21 until the upper right corner of the first housing 21 is in abutting cooperation with the mating groove 94 of the mating block 93, thereby realizing the multi-directional positioning and fixing of the first housing 21, making the first housing 21 more stable during the machining process, and thus making the machining error smaller.

[0043] When machining the second housing 22: First, place the second housing 22 on the upper end of the bottom support base 51, and insert the positioning rod 96 into the cavity of the second housing 22. The positioning rod 96 is in abutting cooperation with the rear wall of the cavity inside the second housing 22. Additionally, make the left end of the second housing 22 in abutting cooperation with the positioning seat 95. Then, by pushing the second housing 22 backward, make the back of the second housing 22 in abutting cooperation with the back support block 52 and the abutting rod 82. At this time, start the first cylinder 31 and the second cylinder 41, and then make the first ejector rod 32 and the second ejector rod 42 move toward the second housing 22 until the first ejector rod 32 and the second ejector rod 42 are in abutting cooperation with the second housing 22. Further, start the first rotary cylinder 53, the second rotary cylinder 61, and the third rotary cylinder 71 to switch the first rotary arm 54, the second rotary arm 62, and the third rotary arm 72 to the working state. Thus, make the first abutting block 56, the second abutting block 74, and the stop block 64 in abutting cooperation with the front end of the second housing 22, and make the inclined surface 65 of the stop block 64 in abutting cooperation with the inclined side of the second housing 22, thereby realizing the multi-directional positioning and fixing of the second housing 22, making the second housing 22 more stable during the machining process, and thus making the machining error smaller.

[0044] Therefore, the present application can machine two battery pack housings with different models simultaneously without changing the structure, has a better multi-point positioning effect, and has a simpler structure, so the cost is lower. Moreover, the three working chambers 10 can machine three battery pack housings simultaneously, thus greatly improving the machining efficiency.
