Detailed implementation mode

[0030] To make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Apparently, the described embodiments are some but not all of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0031] Example 1, please refer to Figure 1-7 , an automotive battery bracket welding positioning tooling, comprising a battery body 1 and a support frame 2. A lifting component 3 is arranged outside the battery body 1, and the lifting component 3 is responsible for lifting the battery body 1 and the support frame 2 so that the top of the battery body 1 contacts the inner top of the support frame 2; a positioning component 4 is arranged at the bottom of the lifting component 3. The positioning component 4 includes a first telescopic component 41. The end of the first telescopic component 41 is fixedly connected with a hollow block 42. A top block 43 is slidably connected to the top of the hollow block. A driving component 5 is arranged on the first telescopic component 41. The driving component 5 is responsible for first stretching the first telescopic component 41 and then pushing the top block 43 to rise so that a welding gap is left between the battery body 1 and the support frame 2.

[0032] Specifically, during the welding process of the battery body 1, a heat dissipation gap needs to be left at the bottom, generally a distance of 1-5 cm needs to be left. After welding, a support pad can be arranged at the bottom of the battery body 1 to play a supporting role.

[0033] When welding the battery body 1 and the support frame 2, in order to improve the welding stability, the first telescopic member 41 can be extended. When it extends to the maximum length, the top block 43 will rise and lift the support frame 2, leaving a welding gap of 1-3 cm between the support frame 2 and the battery body 1, making the welding area larger and the welding more firm.

[0034] In the further embodiment provided by the present invention, a first wedge-shaped block 44 is arranged inside the hollow block 42. A first traction member 45 is fixedly connected to the side end of the first wedge-shaped block 44. A first inclined groove 46 is formed at the bottom of the top block 43. When the first telescopic member 41 is stretched to the longest, the first wedge-shaped block 44 is pulled to move through the first traction member 45, causing the top block 43 to rise.

[0035] The first telescopic member 41 includes a first plate body 411 and a first hollow plate 412. The first plate body 411 slides inside the first hollow plate 412, and the end of the first hollow plate 412 is fixedly connected to the hollow block 42.

[0036] When being pulled by the first traction member 45, the first wedge-shaped block 44 is pulled to move. The first wedge-shaped block 44 causes the top block 43 to rise through the first inclined groove 46 and lifts the support frame 2, enabling the support frame 2 to stably rise to the set height to achieve the purpose of automatic positioning. Then welding can be started.

[0037] Specifically, the top block 43 is in a U shape, and there is an elastic pad on the inner wall to clamp the bottom of the support frame 2 to ensure the stability of its movement.

[0038] In the further embodiment provided by the present invention, an extrusion member 6 is further arranged on the positioning member 4. The extrusion member 6 includes a second telescopic member 61. An activity block 62 is arranged at the end of the second telescopic member 61. A pressing plate 63 is slidably connected to the bottom of the activity block 62. The pressing plate 63 is used to press the support frame 2 downward after welding, and the driving member 5 is also responsible for driving the second telescopic member 61 to move.

[0039] The first telescopic member 41 includes a second plate body 611 and a second hollow plate 612. The second plate body 611 slides inside the second hollow plate 612. A second traction member 64 is fixedly connected to the side end of the second plate body 611. A second wedge-shaped block 65 is fixedly connected to the end of the second traction member 64. A second inclined groove 66 is formed at the top of the pressing plate 63. During the movement of the second wedge-shaped block 65, the pressing plate 63 is pushed downward.

[0040] The principle of the extrusion member 6 is similar to the above. During the pulling process of the second traction member 64, the pressing plate 63 can move downward, push the support frame 2 to move downward, and make it closely attached to the battery body 1, making the welding more firm.

[0041] Specifically, an elastic pad is provided on the bottom surface of the pressing plate 63.

[0042] In a further solution provided by the present invention, the driving component 5 includes a driven shaft 51, a driven gear 52 is fixedly sleeved on the outer end of the driven shaft 51, a first rack 53 is provided on the top surface of the first plate body 411, a second rack 54 is provided on the bottom surface of the second plate body 611, the driven gear 52 is meshed and connected with the first rack 53 and the second rack 54, the first rack 53 is fixedly connected with a first traction member 45, and the second rack 54 is fixedly connected with a second traction member 64; a transmission component 7 is provided on the driving component 5, the transmission component 7 includes a rotating cylinder 71, a driving shaft 72 is arranged inside the rotating cylinder 71, a first bevel gear 73 is fixedly sleeved on the outer end of the driving shaft 72, a driving rod 74 is rotatably connected to the inner wall of the rotating cylinder 71, a second bevel gear 75 is fixedly sleeved on the outer end of the driving rod 74, the first bevel gear 73 is meshed and connected with the second bevel gear 75, belt pulleys 76 are fixedly sleeved on the outer ends of the driving rod 74 and the driven shaft 51, and a transmission belt 77 is connected in a transmission manner outside the belt pulleys 76.

[0043] Specifically, sliding limiting grooves are formed in the first hollow plate 412 and the second hollow plate 612, the sliding limiting grooves are in a cross shape, so that the first rack 53 can just be stuck in the sliding limiting grooves to move, and similarly, the second rack 54 is also stuck in the corresponding sliding limiting grooves to move. Blocks 12 are provided on both the first hollow plate 412 and the second hollow plate 612 (in this case, the blocks 12 are arranged on the inner walls of the sliding limiting grooves). The blocks 12 are made of deformable elastic materials. Initially, the first rack 53 drives the first hollow plate 412 to move, and the second rack 54 drives the second hollow plate 612 to move. When the first telescopic member 41 and the second telescopic member 61 are stretched to the maximum length, the pressure is greater than the elastic force of the blocks 12, so that the first rack 53 starts to slide relative to the first hollow plate 412. At this time, only the first rack 53 slides and drives the top block 43 to rise through the first traction member 45. Similarly, the second rack 54 can also drive the pressing plate 63 to descend.

[0044] Specifically, reset members 11 are fixedly connected to the inner walls of the movable block 62 and the hollow block 42. The reset members 11 include telescopic tubes, and reset springs are sleeved outside the telescopic tubes. One end of one telescopic tube is fixedly connected to the first wedge-shaped block 44, and the end of the other telescopic tube is fixedly connected to the second wedge-shaped block 65.

[0045] The elastic force of the reset spring can help the first rack 53 and the second rack 54 to reset, and can also help the first wedge-shaped block 44 and the second wedge-shaped block 65 to reset.

[0046] In the present invention, the drive shaft 72 is connected to a drive source. During the rotation of the drive shaft 72, the first bevel gear 73 is driven to rotate. The first bevel gear 73 drives the second bevel gear 75 to rotate, so that the second bevel gear 75 drives the driving rod 74 to rotate. Since a transmission belt 77 is sleeved outside a pair of belt pulleys 76, the transmission belt 77 follows the movement and finally drives the driven shaft 51 to rotate, causing the driven gear 52 to start rotating. When the driven gear 52 rotates clockwise, the second hollow plate 612 moves to the right and the first hollow plate 412 moves to the left; when the driven gear 52 rotates counterclockwise, the first hollow plate 412 moves to the right and the second hollow plate 612 moves to the left.

[0047] Initially, both the first telescopic member 41 and the second telescopic member 61 are contracted by half. Then, the driven gear 52 is driven to rotate counterclockwise, causing the first hollow plate 412 to move to the right until the first rack 53 slides relative to the first hollow plate 412, and the support frame 2 is lifted by the top block 43. Then, welding starts. After welding is completed, the driven gear 52 is driven to rotate clockwise, causing the first hollow plate 412 to start contracting and the second hollow plate 612 to move synchronously until the second rack 54 slides relative to the second hollow plate 612, and the support frame 2 is pressed by the pressing plate 63, firmly welding the support frame 2 to the battery body 1, thereby completing the automatic positioning of the support frame 2 in height during welding and improving the welding firmness at the same time.

[0048] The bottom of the rotating cylinder 71 is rotatably connected to a support plate 8, the top of the support plate 8 is rotatably connected to a movable box 9, and a protective frame 10 is provided at the end of the driving rod 74. By pushing the protective frame 10, the first telescopic member 41 and the second telescopic member 61 are rotated to the lower part of the battery body 1.

[0049] The lifting member 3 includes a partition 31 fixedly connected to the inner wall of the movable box 9. A reduction motor 32 is provided above the partition 31. The output end of the reduction motor 32 is fixedly connected to the drive shaft 72. An electromagnet is fixedly sleeved on the outer end of the drive shaft 72. A drive screw rod 33 is sleeved on the outer end of the drive shaft 72. The outer end of the drive screw rod 33 is threadedly sleeved with a drive sleeve 34, and the outer end of the drive sleeve 34 is fixedly connected to a lifting frame 35.

[0050] Initially, the battery body 1 is placed on a pair of lifting frames 35. When the electromagnet is turned on, the drive shaft 72 drives the drive screw rod 33 to rotate together, causing the drive sleeve 34 to drive the lifting frame 35 to rise. Finally, the battery body 1 rises and fits against the inner top of the support frame 2. The electromagnet is turned off, and the rotating cylinder 71 is rotated so that the first telescopic member 41 and the second telescopic member 61 are rotated to the lower part of the battery body 1. Then, the reduction motor 32 can be turned on again for positioning welding.

[0051] In this embodiment, the welding positions of the support frame 2 and the battery body 1 are determined in advance and adapted to the maximum telescopic lengths of the first telescopic member 41 and the second telescopic member 61.

[0052] Embodiment 2. The difference between Embodiment 2 and Embodiment 1 lies in the following technical features: A pair of positioning members 4 and pressing members 6 are provided. The top block 43 and the pressing block are both L-shaped. When a pair of the top blocks 43 or the pressing blocks approach the center, the support frame 2 is squeezed.

[0053] By providing a pair of top blocks 43 and pressing blocks, when the support frame 2 is lifted, the support frame 2 can be clamped between the top blocks 43 or the pressing blocks, thereby further improving the stability of the support frame 2 during welding.

[0054] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of the claims of the present invention.
