Description

Technical Field

[0001] The invention relates to the technical field of automobile battery brackets, in particular to an automobile battery bracket punching device. Background Art

[0002] In new energy electric vehicles, power batteries constitute the power unit. In order to ensure the cruising range of new energy vehicles, it is usually necessary to set up more groups of power batteries. Therefore, the power battery bracket that matches the power battery is particularly important. More mounting holes need to be drilled on the power battery bracket to install the corresponding power batteries, so as to realize the connection of multiple groups of batteries.

[0003] Chinese invention patent CN109822125A discloses such a vehicle battery bracket punching device. The vehicle battery bracket punching device includes a punching bracket, a power device, a plurality of punching drill bits, and a fixture for clamping and fixing the battery bracket. The punching bracket can slide up and down on the external gantry and is arranged above the fixture. A plurality of punching drill bits are rotatably arranged on the lower side of the punching bracket. The power device is linked with the punching drill bit to fix the battery bracket to be punched on the fixture. The punching bracket slides downward to the top of the battery bracket, and the power device drives the punching drill bit to complete the punching of the battery bracket. However, although the use of such a vehicle battery bracket punching device improves work efficiency to a certain extent compared with the traditional method of using a drilling machine to punch holes in the battery bracket one by one, it still has two shortcomings: first, since the battery bracket requires the drilling positions on it to be densely arranged, but due to the limitations of the spatial structure and number of the drilling drill bits, the vehicle battery bracket punching device can only drill holes corresponding to the number of drill bits, so manual secondary drilling is required, the manual drilling accuracy is difficult to control, and it affects work efficiency; second, after the battery bracket with holes is taken out, the battery bracket needs to be manually inspected or other equipment is used to inspect the drilling position, which again affects work efficiency.

[0033] like Figure 1 and Figure 2As shown, a punching device for a battery holder of an automobile comprises a frame 1, one end of the frame 1 is a feeding end, and the other end of the frame 1 is provided with a first punching mechanism 3, a second punching mechanism 4 and a detection mechanism 5 for detecting the drilling position of the battery holder in sequence. The frame 1 is also provided with a conveying mechanism 2 for clamping the battery holder, and the conveying mechanism 2 is sequentially conveyed from the feeding end of the frame 1 to below the first punching mechanism 3, the second punching mechanism 4 and the detection mechanism 5 through the conveying mechanism on the frame 1.

[0034] like Figure 3 As shown, the conveying mechanism 2 includes a base 20, and a support plate 21 for placing a battery holder is provided on the base 20. A plurality of positioning blocks 24 are provided on both sides of a corner of the base 20, and correspondingly, an adjusting cylinder 23 is provided on both diagonal sides of the corner. The adjusting cylinders 23 on both sides push the battery holder to abut against the positioning blocks 24 on both sides of the corner of the base 20, thereby adjusting the position of the battery holder so that the drilling position of the battery holder can better correspond to the drill bit of the punching mechanism. A clamping member 22 is also provided on the base 20, and the clamping member 22 is respectively arranged on the four corners of the base 20. The clamping member 22 includes a telescopic motor 220 and a downward pressing connecting rod 221 linked to the output shaft of the telescopic motor 220. The telescopic motor 220 drives the downward pressing connecting rod 221 to move downward to press the four corners of the battery holder, thereby clamping and fixing the battery holder. The base 20 is evenly provided with a plurality of convex grooves penetrating the upper surface, the convex grooves being perpendicular to the length direction of the frame 1, and the adjusting cylinder 23, the positioning stopper 24 and the telescopic motor 220 are detachably connected to the base 20 through the convex grooves. By adjusting the fixed positions of the adjusting cylinder 23, the positioning stopper 24 and the telescopic motor 220 on the convex grooves, the battery holders of different sizes can be clamped and fixed on the conveying mechanism 2.

[0035] like Figure 4 and Figure 5As shown, the first punching mechanism 3 and the second punching mechanism 4 have the same structure. The first punching mechanism 3 is selected for explanation. The first punching mechanism 3 includes a lifting cylinder 300, which is installed in the punching box 30 above the frame 1. The piston rod of the lifting cylinder 300 is connected to the lifting seat 31. The lifting seat 31 is mounted on the column of the punching box 30 and can slide up and down along the column. The punching motor 34 is installed on the lifting seat 31 and extends the motor shaft downward. The motor shaft is connected to the input end of the rotating shaft 38 through the first synchronous belt gear 36. The output end of the rotating shaft 38 is connected to the second synchronous belt gear 37. The second synchronous belt gear 37 extends a plurality of output shafts downward and is respectively connected to the drilling mechanism 39. The lifting seat 31 is controlled to move up and down along the column of the punching box 30 by the setting of the lifting cylinder 300. The first synchronous belt gear 36 is driven to rotate by the rotation of the punching motor 34. The first synchronous belt gear 36 drives the second synchronous belt gear 37 to rotate through the rotating shaft 38, thereby driving the drilling mechanism 39 to punch holes on the battery bracket. By setting up the first punching mechanism 3 and the second punching mechanism 4 to punch holes in the battery bracket, the punching density and punching accuracy of the battery bracket can be high, eliminating the offline manual secondary punching step and improving work efficiency. Since the first punching mechanism 3 and the second punching mechanism 4 have the same structure, they can be used simultaneously or selectively according to the needs of the battery bracket drilling position.

[0036] The lower end of the lifting seat 31 is also provided with a slidingly connected side shift plate 35, and the side shift plate 35 can slide outward from the top of the frame 1 to the side space of the frame 1. The first synchronous belt gear 36 connected to the punching motor 34 is fixedly arranged on the bottom surface of the lifting seat 31, the upper end of the rotating shaft 38 is sleeved with a gear and meshed with the synchronous belt outer gear of the first synchronous belt gear 36, the lower end of the rotating shaft 38 extends into the second synchronous belt gear 37, and drives the second synchronous belt gear 37 to rotate, and the second synchronous belt gear 37 and the connected drilling mechanism 39 are fixedly arranged on the side shift plate 35. At the same time, a handle for convenient pulling is provided on the side of the side shift plate 35 facing outward. Through the setting of the side shift plate 35, when the side shift plate 35 slides outward from the top of the frame 1 to the side of the frame 1, the first synchronous belt gear 36 is disconnected from the rotating shaft 38, and the power of the punching motor 34 is cut off, so as to facilitate the regular inspection or maintenance of the drilling mechanism 39 connected to the side shift plate 35. After the side shift plate 35 is reset, the first synchronous belt gear 36 is reconnected with the second synchronous belt gear 37 via the rotating shaft 38 to restore the punching power.

[0037] A side shift sliding mechanism is provided between the lower surface of the lifting seat 31 and the upper surface of the side shift plate 35. Specifically, an intermediate connecting plate 350 is provided between the lifting seat 31 and the side shift plate 35. The lower surface of the lifting seat 31 and the upper surface of the side shift plate 35 are respectively provided with a first guide rail 351 and a second guide rail 352 perpendicular to the length direction of the frame 1. The upper surface and the lower surface of the intermediate connecting plate 350 are respectively provided with corresponding upper and lower sliders that are displaced up and down. The intermediate connecting plate 350 is slidably connected to the first guide rail 351 and the second guide rail 352 through the upper slider and the lower slider. At the same time, a U-shaped opening is provided on one side of the intermediate connecting plate 350 facing outward, so that the rotating shaft 38 can pass through when moving. By setting the intermediate connecting plate 350, when the side shift plate 35 slides toward the outside of the side of the frame 1, it forms a sliding track with two connected upper and lower sections, so that the moving path of the side shift plate 35 is lengthened, so that the drilling mechanism 39 connected to the side shift plate 35 can be completely and smoothly moved out to the side of the frame 1, further facilitating the maintenance of the drilling mechanism 39.

[0038] The lower surface of the lifting seat 31 is also provided with a blocking member 32 and a positioning member 33. The blocking member 32 includes an upper blocking column 320 and a lower blocking column 321. The upper blocking column 320 and the lower blocking column 321 are respectively fixedly arranged on the lower surface of the lifting seat 31 through a fixed support. The upper blocking column 320 and the lower blocking column 321 are respectively abutted against the end of the upper slider of the intermediate connecting plate 350 and the end of the side shift plate 35. When the side shift plate 35 is moved out to the side of the frame 1 and then moved back to its original position by the setting of the blocking member 32, the upper blocking column 320 and the lower blocking column 321 respectively position the intermediate connecting plate 350 and the side shift plate 35, so that the side shift plate 35 moves back to its original position. The positioning member 33 includes a positioning cylinder 330 and a positioning column 331 linked thereto. The positioning cylinder 330 drives the positioning column 331 to move up and down. The side shift plate 35 is provided with a corresponding positioning hole corresponding to the downward moving path of the positioning column 331. Through the setting of the positioning member 33 , the positioning cylinder 330 drives the positioning column 331 to move downward and extend into the positioning hole on the side shift plate 35 for fixation, thereby preventing the side shift plate 35 from sliding toward the outside of the frame 1 after being reset.

[0039] like Figure 6As shown, the drilling mechanism 39 includes a plurality of gear boxes, and a punching drill group is arranged inside the gear box. The punching drill group includes two meshingly connected punching drill rows, and each punching drill row includes a first main shaft gear 391, a first transition gear 392 and a slave shaft gear 393. The two ends of the first main shaft gear 391 are respectively meshed and connected to a plurality of slave shaft gears 393 through the first transition gear 392, and the lower ends of the first main shaft gear 391 and the slave shaft gear 393 are respectively rotatably connected to the punching drills, thereby forming a punching drill row with the same rotation direction and equal distance intervals. The first main shaft gears 391 of the two adjacent punching drill rows are meshed and connected through the transition gear 390 to form a punching drill group. The upper end of the transition gear 390 is provided with an upward output shaft, and the output shaft is respectively coaxially connected to the downward output shaft of the second synchronous belt gear 37, so that the punching drill group is driven to rotate through the second synchronous belt gear 37.

[0040] like Figure 7 and Figure 8 As shown, a detection mechanism 5 is also provided at the rear end of the second punching mechanism 4. The detection mechanism 5 includes a detection bracket 51. The detection bracket 51 is arranged inside the detection box 50 and can slide up and down along the pillars of the detection box 50. The elastic telescopic member 52 is sleeved on the detection bracket 51 and corresponds one-to-one with the drill holes on the battery bracket. The elastic telescopic member 52 includes a first connecting block 523 sleeved on the detection bracket 51. A pair of elastic structures are symmetrically provided on both sides of the bottom of the first connecting block 523. The elastic structure includes a guide column sleeve 522. The protruding ends of the guide columns of the guide column sleeve 522 are respectively connected to the second connecting block 524. The outside of the guide columns are respectively sleeved with springs. The two ends of the springs are respectively pressed onto the column ends of the guide column sleeve 522 and the upper surface of the second connecting block 524. The top column 520 passes through the first connecting block 523 and is connected to the first connecting block. 523 is connected by clearance fit, and a limit block is mounted on the top column 520 above the first connection block 523, and a bottom column 521 is provided at the lower end of the corresponding top column 520, and the upper end of the bottom column 521 abuts against the lower end of the top column 520, and the lower end of the bottom column 521 passes through the second connection block 524 and protrudes from the second connection block 524, and the bottom column 521 and the second connection block 524 are connected by interference fit or threaded fixed connection, and the bottom column 521 can also be an integral structure with the second connection block 524. The lower end of the bottom column 521 extends into the drilling position of the battery bracket. If the drilling position hole is missed, the bottom column 521 is pushed up, and the abutting top column 520 is pushed up at the same time, driving the limit plate connected to its upper end to move upward, and the projection of the limit plate is detected by the shooting sensor 52, thereby sending an alarm signal of missed drilling position. Because the guide post sleeve 522 is provided with a spring, the bottom post 521 moving upward is automatically restored under the action of the guide post sleeve 522, and the corresponding top post 520 also moves downward and automatically restores, thereby facilitating the next detection. In order to simplify the structure, the piston guide post sleeve 522 can be replaced with a spring.

[0041] A pull-out mechanism is also provided between the detection bracket 51 and the detection box 50, and the pull-out mechanism includes a slide rail 54 fixedly arranged on the inner wall of the detection box 50, and the two sides of the detection bracket 51 are slidably installed in the slide rail 54. In this way, the detection bracket 51 can slide outward from the top of the frame 1 to the empty space on the side of the frame 1, so as to facilitate regular inspection of the elastic expansion member 52 or the beam sensor 53 mounted on the detection bracket 51 or replacement of the damaged ones.

[0042] An electrical control cabinet 6 and a debris collection box 7 are also provided at the rear end of the detection mechanism 5. The electrical control cabinet 6 provides the required air source for the entire battery bracket punching device. The debris collection box 7 collects the debris punched by the two punching mechanisms through the transmission mechanism on the frame 1 for convenient unified processing.
