DETAILED DESCRIPTION

[0024] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0025] use Figure 1 The present invention describes a jig for thermoplastic molding of a battery box guard plate for a new energy vehicle. The jig can be used in the thermoplastic molding process of the battery box guard plate, as well as in the thermoplastic molding process of other types of boxed items.

[0026] First, use Figure 1 and Figure 2 , the overall structure of the fixture for thermoplastic molding of the new energy vehicle battery box guard plate is explained. Figure 1 It is a schematic diagram of the three-dimensional structure of the utility model. Figure 2 It is a schematic diagram of the three-dimensional structure of the first clamping mechanism in the present utility model.

[0027] The jig for thermoplastic molding of a battery box guard plate for a new energy vehicle comprises a tooling platform 1, a plurality of first clamping mechanisms, an elastic pressing assembly, a clamp opening and closing assembly, and a plurality of second clamping mechanisms, wherein:

[0028] The workbench 1 is in the shape of a rectangular frame, which is used to install a plurality of first clamping mechanisms, elastic pressing components, clamp opening and closing components and a plurality of second clamping mechanisms;

[0029] Several first clamping mechanisms, such as Figure 1As shown, only four first clamping mechanisms are shown, and the four first clamping mechanisms are arranged around the tooling table 1. The four first clamping mechanisms can be used to clamp the first layer of fabric 100.

[0030] Each first clamping mechanism comprises a clamping plate 2, several chucks 3, and a rotating shaft 4. The clamping plate 2 is mounted on top of the workbench 1. The first end of each chuck 3 is fixedly mounted to the rotating shaft 4, and the chucks 3 are arranged in a spaced-apart pattern. The rotating shaft 4 is rotatably mounted on the top surface of the workbench 1. A tension spring 5 is installed at the bottom of each chuck 3, which enables the chuck 3 to clamp around all four sides of the first layer of fabric 100.

[0031] An elastic pressing assembly is located at the bottom of the clamping plate 2. Specifically, each first clamping mechanism is equipped with several elastic pressing assemblies, which are spaced apart on the clamping plate 2. The elastic pressing assemblies consistently tend to force the clamping plates 2 upward. After the clamping plates 2 and clamping heads 3 of the four first clamping mechanisms clamp the first layer of fabric 100, and the hydraulic press presses downward on the first layer of fabric 100, the first layer of fabric 100 and the clamping plates 2 are moved downward by the elastic pressing assemblies, with a tendency to return upward.

[0032] The chuck opening and closing components are arranged between the clamping plate 2 and the tooling table 1. Specifically, each clamping plate 2 is provided with a plurality of groups of chuck opening and closing components, and the plurality of groups of chuck opening and closing components are arranged on the clamping plate 2 at intervals.

[0033] The chuck opening and closing assembly is configured so that the chuck 3 can be opened when the first layer of fabric 100 and the clamping plate 2 move downward. The chuck opening and closing assembly includes a top block 6 and a rotating plate 7. The first end of the rotating plate 7 is fixedly mounted to the rotating shaft 4, and the bottom end of the top block 6 is mounted to the workbench 1. The clamping plate 2 is provided with an escape hole. The top end of the top block 6 passes through the clamping plate 2 and abuts against the second end of the rotating plate 7.

[0034] When the hydraulic press presses down the first layer of fabric 100, the first layer of fabric 100 and the clamping plate 2 move downward. During the downward movement, the top end of the top block 6 drives the rotating plate 7 to rotate, and the rotating plate 7 is linked to the rotating shaft 4 to rotate. The rotating rotating shaft 4 is linked to the chuck 3 to open, so that the first layer of fabric 100 can be detached from the clamping plate 2 and the chuck 3, and move downward with the downward pressure of the hydraulic press.

[0035] Several second clamping mechanisms are distributed on both sides of each clamping plate 2 and are lower than the height of the clamping plate 2, such as Figure 1 As shown, the second clamping mechanism is a hinged positioner 11, Figure 1Only eight hinged retainers 11 are shown, used to clamp the second layer of fabric 200. The second layer of fabric 200 can be four strips of fabric, with one second layer of fabric 200 positioned between two opposing hinged retainers 11. Four strips of second layer of fabric 200 are positioned on the eight hinged retainers 11. When the first layer of fabric 100 is disengaged from the clamping plate 2 and the chuck 3 and moves downward onto the four strips of second layer of fabric 200 as the hydraulic press presses downward, the first layer of fabric 100 and the four strips of second layer of fabric 200 are thermoplastically formed together, completing the thermoplastic forming of the battery compartment cover.

[0036] In this embodiment, through the cooperation of the clamping plate 2, several clamps 3 and the rotating shaft 4, the four sides of the first layer of fabric 100 can be clamped and installed on the four sides of the workbench 1, thereby completing the positioning of the first layer of fabric 100; the second layer of fabric 200 can be clamped and installed to the bottom position of the first layer of fabric 100 through the hinged positioner 11. When the first layer of fabric 100 and the second layer of fabric 200 are thermoplastically formed, the hydraulic press presses the first layer of fabric 100 downward, and the first layer of fabric 100 and the clamping plate 2 move downward. At this time, the top end of the top block 6 drives the rotating plate 7 to rotate, and the rotating plate 7 rotates in conjunction with the rotating shaft 4. The rotating rotating shaft 4 rotates in conjunction with the clamping head 3 to open, so that the first layer of fabric 100 can be separated from the clamping plate 2 and the clamping head 3, and the first layer of fabric 100 is pressed down onto the second layer of fabric 200. That is, the first layer of fabric 100 and the second layer of fabric 200 are thermoplastically formed, and the processing of the battery box guard plate is completed. After the processing is completed, the clamping plate 2 can return to its original position through the elastic pressing component. The overall structure is simple and the manufacturing cost is low. In addition, compared with existing equipment, the first layer of fabric 100 can be smoothly and synchronously released during the pressing process, avoiding the problem of the clamping part of the equipment loosening and stagnating during the hot pressing process, and the problem of hot pressing and loosening being out of sync, thereby improving production quality.

[0037] In some embodiments, as Figure 2 As shown, the elastic pressing assembly includes a guide column 8 and an elastic member 9. The top end of the guide column 8 is slidably mounted on the clamping plate 2, and the bottom end of the guide column 8 is mounted on the workbench 1. A limit member is fixedly mounted on the top surface of the guide column 8 to allow the clamping plate 2 to slide within the travel of the guide column 8. The elastic member 9 is sleeved between the clamping plate 2 and the elastic member 9. In this embodiment, through the cooperation of the guide column 8 and the elastic member 9, the clamping plate 2 pressed downward can have a tendency to always move upward, so that the clamping plate 2 can automatically return to its initial position.

[0038] In some embodiments, as Figure 2As shown, a mounting sleeve 10 for mounting the tension spring 5 is mounted on the bottom end surface of the clamping plate 2, and the mounting sleeve 10 is arranged in a U shape. There are several mounting sleeves 10 on the bottom end surface of each clamping plate 2, and several mounting sleeves 10 correspond to several clamping heads 3.

[0039] The clamping plate 2 has a clearance opening for the tension spring 5. The first end of the tension spring 5 passes through the clamping plate 2 and is mounted to the bottom of the chuck 3. The second end of the tension spring 5 is mounted to the inner bottom wall of the mounting sleeve 10. In this embodiment, the tension spring 5 constantly applies a downward clamping force to the chuck 3, thereby providing the chuck 3 with a clamping function.

[0040] In some embodiments, as Figure 2 As shown, a plurality of bearing assemblies adapted to the rotating shaft 4 are mounted on the clamping plate 2. The plurality of bearing assemblies are spaced apart on the top surface of the clamping plate 2. The rotating shaft 4 is rotatably mounted to the top of the clamping plate 2 via the bearing assemblies. In this embodiment, the rotating shaft 4 is provided with a rotation function by the bearing assemblies.
