Description

Technical Field

[0001] This utility model relates to a fixture for friction welding of energy storage boxes, belonging to the technical field of energy storage box production equipment. Background Technology

[0002] Energy storage refers to the process of storing energy through a medium or device and releasing it when needed. For example, renewable energy sources such as solar and wind power can be converted into electricity through energy storage technology. This can stably provide clean energy without being affected by fluctuations in the supply of renewable energy. It helps to solve the imbalance between energy supply and demand, improve energy efficiency, and promote the development of renewable energy. Therefore, energy storage technology is of great significance in the energy field today.

[0003] Battery energy storage is one of the main energy storage technologies at present. The main function of the battery box shell is to protect the battery cells and other related components from the influence of the external environment. It can also play a role in waterproofing, dustproofing, and shockproofing. In addition, the battery box shell can also improve the heat dissipation performance of the battery to maintain the stability and safety of the battery pack.

[0004] The energy storage box shell is formed from profiles through cutting, stamping, bending, and welding. Due to the use of a high-efficiency, high-quality automated friction welding process, the bent sheet metal must not move at all during welding to avoid welding failure. Furthermore, the sheet metal must be accurately positioned to prevent welding errors. Therefore, a fixture is needed to stably hold and precisely position the bent sheet metal to ensure successful friction welding. Summary of the Invention

[0005] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a simple, stable, and precise fixture for friction welding of energy storage boxes.

[0008] The top of the suspended support is a rectangular flat plate, which provides planar support and positioning for the plate after it is bent into a rectangular frame structure and then fitted into the suspended support.

[0009] The end alignment device abuts against the end of the plate that is fitted into the suspended support and positions the end of the plate.

[0010] The side alignment device includes a side positioning plate fixed to the front side of the base and located in front of the suspended support, and a side pushing mechanism fixed to the rear side of the base and located behind the suspended support; the side pushing mechanism pushes the rear part of the plate sleeved on the suspended support, so that the front part of the plate abuts against the side positioning plate, thereby achieving side positioning of the plate.

[0011] There are two sets of the pressing device, which are symmetrically arranged on the front and rear sides of the base to press and fix the upper part of the plate on the suspended support.

[0012] The bottom pushing device is located on the left side of the base and is used to push the bottom of the plate on the suspended support to press and fix the bottom of the plate.

[0013] Furthermore, the end alignment device includes an end alignment cylinder fixedly mounted on the right side of the base and an end alignment plate installed on the movable end of the end alignment cylinder; the end alignment plate is driven by the end alignment cylinder to the left to abut against the right end face of the plate, thereby achieving end positioning.

[0014] Furthermore, the side-push mechanism includes a side-push cylinder fixed to the rear side of the base and a side-push plate installed at the movable end of the side-push cylinder; the side-push cylinder pushes the side-push plate forward to abut against the rear side of the plate, so that the front side of the plate abuts against the side positioning plate, thereby achieving side positioning of the plate.

[0015] Furthermore, the side alignment device includes multiple sets of side pushing mechanisms arranged in parallel on the rear side of the base.

[0016] Furthermore, the pressing device includes multiple sets of pressing mechanisms arranged in parallel on the front or rear side of the base. Each pressing mechanism includes an L-shaped pressing rod with one end hinged to the front or rear side of the base, a pressing block at the other end of the L-shaped pressing rod, and a pressing cylinder that hinges the middle of the L-shaped pressing rod to the base. The pressing cylinder pushes the L-shaped pressing rod to rotate, causing the pressing block to press the upper part of the plate.

[0017] Furthermore, the pressing mechanism has five sets.

[0018] Furthermore, the bottom pushing device includes two brackets symmetrically installed on the front and rear sides of the left end of the base, two bottom pushing cylinders respectively vertically inverted on the two brackets, and a horizontal pushing plate fixedly connected to the movable ends of the two bottom pushing cylinders; the horizontal pushing plate is driven by the two bottom pushing cylinders to press the bottom of the plate upward.

[0019] Furthermore, a guide seat is installed on the bracket, and a guide column is vertically fixed on the horizontal push plate; the guide column is embedded in the guide seat to provide guidance for the lifting and lowering of the horizontal push plate.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

Detailed Implementation

[0028] See Figures 1-3 The present invention relates to a jig for friction welding of an energy storage box, comprising a base 1, a suspended support 2 with the left end suspended and the right end fixed to the right side of the base 1, an end alignment device 3 installed on the right side of the base 1, a side alignment device 4 and a pressing device 5 set on the front and rear sides of the base 1, and a bottom pushing device 6 set on the left side of the base 1.

[0029] The top of the suspended support 2 is a rectangular flat plate. After the plate, which is bent into a rectangular frame structure, is put into the suspended support 2, it provides planar support and positioning for the plate.

[0030] The end alignment device 3 includes an end alignment cylinder 31 fixedly mounted on the right side of the base 1 and an end alignment plate 32 installed on the movable end of the end alignment cylinder 31. The end alignment plate 32 is driven by the end alignment cylinder 31 to the left to abut against the right end face of the plate, and to press against the right end of the plate fitted into the suspended support 2, thereby achieving the positioning of the end of the plate.

[0031] The side alignment device 4 includes a side positioning plate 41 fixedly mounted on the front side of the base 1 and located in front of the suspended support 2, and multiple sets of side pushing mechanisms 42 fixedly mounted parallel to the rear side of the base 1 and located behind the suspended support 2. In this embodiment, there are six sets of side pushing mechanisms 42 to ensure that the plate is pushed evenly and the plate is moved parallel as a whole to prevent it from being pushed off-center. The side pushing mechanism 42 includes a side pushing cylinder 43 fixedly mounted on the rear side of the base 1 and a side pushing plate 44 installed at the movable end of the side pushing cylinder 43. The side pushing cylinder 43 pushes the side pushing plate 44 forward to abut against the rear side of the plate, so that the front side of the plate abuts against the side positioning plate 41, thereby achieving side positioning of the plate.

[0032] There are two sets of pressing devices 5, which are symmetrically arranged on the front and rear sides of the base 1 to press and fix the upper part of the plate on the suspended support 2. Specifically, the pressing device 5 includes five sets of pressing mechanisms arranged in parallel on the front or rear side of the base 1. The pressing mechanism includes an L-shaped pressing rod 51 with one end hinged to the front or rear side of the base 1, a pressing block 52 arranged on the other end of the L-shaped pressing rod 51, and a pressing cylinder 53 that hinges the middle part of the L-shaped pressing rod 51 to the base 1. The pressing cylinder 53 pushes the L-shaped pressing rod 51 to rotate, so that the pressing block 52 presses the upper part of the plate.

[0033] The bottom pushing device 6 is located on the left side of the base 1 and is used to push the bottom of the plate on the suspended support 2 to press and fix the bottom of the plate. The bottom pushing device 6 includes two brackets 61 symmetrically installed on the front and rear sides of the left end of the base 1, two bottom pushing cylinders 62 respectively vertically mounted on the two brackets 61, and a horizontal pushing plate 63 fixedly connected to the movable ends of the two bottom pushing cylinders 62. The horizontal pushing plate 63 is driven upward by the two bottom pushing cylinders 62 to press the bottom of the plate. Furthermore, a guide seat 64 is installed on the bracket 61, and a guide column 65 is vertically fixed on the horizontal pushing plate 63. The guide column 65 is vertically embedded in the guide seat 64 to provide guidance for the lifting and lowering of the horizontal pushing plate 63.

[0034] During operation, the operator first inserts the plate to be welded, bent into a rectangular frame structure, into the suspended support 2, ensuring the right end of the plate abuts against the end alignment plate 32 of the end alignment device 3, thus positioning the plate in the left-right direction. Then, the side-push cylinder 43 of the side alignment device 4 is activated, pushing the side-push plate 44 forward to abut against the rear side of the plate, causing the front side of the plate to abut against the side positioning plate 41, thus positioning the plate in the front-back direction. After positioning in the left-right and front-back directions, the edge-pressing cylinder 53 of the edge-pressing device 5 is activated, pushing the L-shaped pressure rod 51 to rotate, causing the pressing block 52 to press against the upper part of the plate, thus securing the upper part of the plate. Finally, the two bottom-push cylinders 62 of the bottom-push device 6 jointly drive the horizontal push plate 63 upwards to abut against the bottom of the plate, thus securing the bottom of the plate. At this point, the plate's position positioning and fixation are complete, and the friction welding machine can be started to weld the joint at the top of the plate.

[0035] Additionally, it should be noted that the above-described specific implementation is merely an optimized solution of this patent, and any modifications or improvements made by those skilled in the art based on the above concept are within the scope of protection of this patent.
