Detailed implementation manners

[0027] The following are specific embodiments of the present utility model in combination with the accompanying drawings to further describe the technical solutions of the present utility model, but the present utility model is not limited to these embodiments.

[0028] Such as Figure 1-9As shown in the figure, the bonding tooling for the inner support reinforcing rib of the automotive battery box of the present invention includes a base 1. On one side of the top of the base 1, a side fixing plate 2 is fixedly installed. On the side of the side fixing plate 2, a fixing seat 3 is fixedly installed. On the side of the fixing seat 3, an inner battery box pressing component 6 is fixedly installed. In the middle of the top of the base 1, a placing seat 4 is fixedly installed. On the outer side of the placing seat 4, an outer battery box pressing component 5 is arranged. The inner battery box pressing component 6 and the outer battery box pressing component 5 are drivingly connected to each other.

[0029] Specifically, through the driving cooperation between the outer battery box pressing component 5 and the inner battery box pressing component 6, during the bonding process of the inner support reinforcing rib of the automotive battery box, the inside and outside of the automotive battery box can be synchronously limited and pressurized, ensuring the bonding structural strength between the inner support reinforcing rib of the battery box and the inner and outer shells of the battery box of the bicycle, and avoiding the influence on the structural strength of the automotive battery box due to the insecure bonding of the inner support reinforcing rib of the battery box.

[0030] As Figure 1 、 Figure 5 and Figure 7 shown in the figure, for the bonding tooling for the inner support reinforcing rib of the automotive battery box of the present invention, the outer battery box pressing component 5 includes four outer fixing plates 501. The bottoms of the four outer fixing plates 501 are rotatably connected to the four side edges of the placing seat 4. At the centers of one sides of the four outer fixing plates 501, U-shaped blocks 502 are fixedly installed. Inside the four U-shaped blocks 502, connecting rods 503 are rotatably connected. At the four side edges of the connection position between the placing seat 4 and the base 1, convex sliding grooves 504 are opened. Inside the convex sliding grooves 504, lead screw seats 505 are slidably connected. At the top of the lead screw seat 505, an installation frame 507 is fixedly installed. The installation frame 507 is rotatably connected to the bottom of the connecting rod 503.

[0031] At the corners on both sides of the inner wall of the convex sliding groove 504, two parallel limiting rods 510 are fixedly installed. On both sides of the lead screw seat 505, insertion holes adapted to the limiting rods 510 are opened. The two limiting rods 510 are inserted into the insertion holes. At the centers of both sides of the inner wall of the convex sliding groove 504, a trapezoidal lead screw 506 is rotatably connected. The trapezoidal lead screw 506 is threadedly connected to the center of the lead screw seat 505.

[0032] A cavity 508 is opened at the center of the placing seat 4. The ends of the four trapezoidal lead screws 506 all extend into the cavity 508 and are fixedly installed with first bevel gears 509. The four first bevel gears 509 are meshed with each other in pairs.

[0033] Specifically, the four trapezoidal lead screws 506 are meshed through the first bevel gears 509. When one trapezoidal lead screw 506 rotates, it drives the four trapezoidal lead screws 506 to rotate synchronously. The rotation of the trapezoidal lead screw 506 drives the movement of the lead screw seat 505. The trapezoidal lead screw 506 has a self-locking effect. When the lead screw seat 505 moves to the set position, the lead screw seat 505 can be fixed. The movement of the lead screw seat 505 squeezes the rotation of the connecting rod 503, and the connecting rod 503 pushes the rotation of the outer fixing plate 501, so that the outer fixing plate 501 is in close contact with the outer wall of the automotive battery box.

[0034] As Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown in

[0035]

[0036]

[0037] Figure 2 Figure 8 As Figure 2 and Figure 8As shown in the figure, for the bonding tooling of the support reinforcing rib inside the automotive battery box of the present invention, the transmission assembly 7 includes a fixed box 701, a mounting plate 702, a servo motor 703, a worm gear 704, and a bidirectional worm 705. The fixed box 701 is fixedly installed on the back of the side fixing plate 2. On one side of the inner wall of the fixed box 701, two mounting plates 702 are fixedly installed. A bidirectional worm 705 is rotatably connected between the two mounting plates 702. The other ends of the two first connecting shafts 619 extend into the fixed box 701 and are both fixedly installed with worm gears 704. The two worm gears 704 are meshed and connected to both sides of the bidirectional worm 705. On the side of one of the mounting plates 702, a servo motor 703 is fixedly installed. The output shaft of the servo motor 703 is fixedly connected to one end of the bidirectional worm 705.

[0038] Specifically, the servo motor 703 drives the bidirectional worm 705 to rotate. The bidirectional worm 705 meshes with the two worm gears 704, thereby driving the two worm gears 704 to rotate. The rotation directions of the two worm gears 704 are opposite. The rotation of the worm gears 704 drives the two first connecting shafts 619 to rotate. The two first connecting shafts 619 are connected to two longitudinally arranged rotating rods 615 through couplings, thereby driving the two longitudinally arranged rotating rods 615 to rotate. The longitudinally arranged rotating rod 615 and the laterally arranged rotating rod 615 are meshed through a second bevel gear 617 and a third bevel gear 618, thereby realizing the synchronous rotation of the four rotating rods 615. The rotation of the rotating rod 615 drives the inner fixing plate 613 to rotate, so that the inner fixing plate 613 contacts the inner wall of the automotive battery box.

[0039] It should be noted that the rotation angle of the inner fixing plate 613 of the present application is limited. When the inner fixing plate 613 rotates counterclockwise, when the inner fixing plate 613 contacts the bottom of the vertical plate 605, it can no longer rotate.

[0040] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 9 As shown in the figure, for the bonding tooling of the support reinforcing rib inside the automotive battery box of the present invention, an inner support assembly is provided at the bottom of the fixed frame 604. The inner support assembly includes a vertical plate 605 and a top block 606. At the center of the four side edges at the bottom of the fixed frame 604, vertical plates 605 are fixedly installed. U-shaped grooves are opened at the bottoms of the four vertical plates 605. On both sides of the inner wall of the U-shaped groove, limiting columns 608 are fixedly provided. A top block 606 is arranged inside the U-shaped groove. A through groove 607 is opened in the middle of the top block 606. The two limiting columns 608 are slidably located inside the through groove 607. One end of the top block 606 is in contact connection with the back of the inner fixing plate 613.

[0041] A fixed disk 611 is provided at the center of the fixed frame 604, and four strip-shaped connecting blocks 612 are equidistantly connected to the outer edge of the fixed disk 611 for rotation. The four strip-shaped connecting blocks 612 are rotatably connected to the other end of the corresponding top block 606. A connecting column 610 is fixedly installed at the center of the fixed disk 611, and a U-shaped frame 601 is fixedly installed at the top of the fixed frame 604. An electric hydraulic cylinder 602 is fixedly installed at the center of the top of the U-shaped frame 601, and the telescopic end of the electric hydraulic cylinder 602 is fixedly connected to the top of the connecting column 610.

[0042] Specifically, the downward movement of the connecting column 610 by the electric hydraulic cylinder 602 will push the fixed plate 611 downward. During the downward movement of the fixed plate 611, the strip connecting block 612 will be squeezed to rotate. The rotation of the strip connecting block 612 will push the top block 606 to move. The top block 606 can support the inner fixing plate 613, so that the inner fixing plate 613 is in close contact with the inner wall of the car battery box.

[0043] It should be noted that the electric hydraulic cylinder 602 is purchased on the market and is directly used in this application without further elaboration.

[0044] A strip groove is provided on the side of the connecting column 610, and a tooth groove 620 is provided on the groove wall of the strip groove. A second connecting shaft 8 is rotatably connected between the U-shaped frame 601 and the side fixed plate 2. A circular gear 11 is fixedly installed on one end of the second connecting shaft 8, and the circular gear 11 is meshed with the tooth groove 620. A third connecting shaft 12 is rotatably connected to the bottom of the side fixed plate 2. One end of the third connecting shaft 12 extends to the interior of the placement seat 4 and is fixedly connected to one end of the corresponding trapezoidal screw 506. A sprocket 9 is fixedly installed on the other end of the second connecting shaft 8 and the other end of the third connecting shaft 12, and a transmission chain 10 is connected between the two sprockets 9.

[0045] Specifically, when the electric hydraulic cylinder 602 pushes the connecting column 610 to move downward, the connecting column 610 will drive the circular gear 11 to rotate. The circular gear 11 is fixedly connected to the second connecting shaft 8, thereby driving the second connecting shaft 8 to rotate. The second connecting shaft 8 and the third connecting shaft 12 are transmitted through the sprocket 9 and the transmission chain 10. When the second connecting shaft 8 rotates, it will drive the third connecting shaft 12 to rotate, and the rotation of the third connecting shaft 12 will drive the connected trapezoidal screw 506 to rotate.

[0046] In specific implementation, when using the bonding tool to perform internal support and reinforcement bonding on the automobile battery box, first place the automobile battery box to be processed on the top of the placement seat 4, then turn on the servo motor 703, the servo motor 703 drives the rotation of the bidirectional worm 705, the bidirectional worm 705 is engaged with the two worm wheels 704, thereby driving the two worm wheels 704 to rotate, the two worm wheels 704 rotate in opposite directions, thereby driving the two first connecting shafts 619 to rotate, the two first connecting shafts 619 and the two longitudinally arranged rotating rods 615 are driven by a coupling, thereby driving the two longitudinal rotating rods 615 to rotate, one of the longitudinal rotating rods 615 and the two transversely arranged rotating rods 615 are engaged and driven by the second bevel gear 617 and the third bevel gear 618, thereby realizing the synchronous rotation of the four rotating rods 615, and the four rotating rods 615 drive the inner fixing plate 613 to rotate, so that the inner fixing plate 613 contacts the inner wall of the automobile battery box;

[0047] Next, the electric hydraulic cylinder 602 is turned on, pushing the connecting column 610 downward. The connecting column 610 pushes the fixing plate 611 downward. During the downward movement of the fixing plate 611, the strip-shaped connecting block 612 is rotated. During the rotation of the strip-shaped connecting block 612, the top block 606 is moved, so that the end of the top block 606 abuts against the center of the side of the inner fixing plate 613, so that the inner fixing plate 613 is in close contact with the inner wall of the vehicle battery box.

[0048] When the connecting column 610 is in the process of moving downward, the tooth groove 620 on the side of the connecting column 610 is engaged with the circular gear 11, thereby driving the second connecting shaft 8 to rotate. The second connecting shaft 8 and the third connecting shaft 12 are transmitted through the sprocket 9 and the transmission chain 10, thereby driving the third connecting shaft 12 to rotate. The third connecting shaft 12 is connected to the corresponding trapezoidal screw 506, thereby driving the connected trapezoidal screw 506 to rotate. The four trapezoidal screws 506 are engaged with each other through the first bevel gear 509, thereby driving the four trapezoidal screws 506 to rotate synchronously. The screw seat 505 is driven to move by the trapezoidal screw 506. During the movement of the screw seat 505, the connecting rod 503 is squeezed to rotate. The connecting rod 503 pushes the outer fixing plate 501 to make close contact with the outer wall of the battery box. During the bonding process of the support reinforcement ribs inside the automobile battery box, the inside and outside of the automobile battery box can be synchronously limited and pressurized, ensuring the bonding structural strength between the support reinforcement ribs inside the bicycle battery box and the inner and outer shells of the battery box, avoiding the structural strength of the automobile battery box being affected by the loose bonding of the support reinforcement ribs inside the battery box.
