[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example

[0029] See also Figure 1-Figure 5 , the utility model provides the following technical solutions:

[0030] A housing fixing device for spray painting an electric vehicle housing, comprising:

[0031] Fixed base 20;

[0032] Sliding grooves 10, two sliding grooves 10 are provided, and both sliding grooves 10 are opened at the upper end of the fixed base 20;

[0033] Fixed assembly, the fixed assembly is provided with two groups, each group of fixed assemblies includes a mobile clamping block 1, a hydraulic groove 2, an adjustment hole 3, an adjustment rod 4, a fitting block 5, a rubber pad 6 and a bottom plate 7, and there are multiple adjustment holes 3, adjustment rod 4, fitting block 5 and rubber pad 6. The mobile clamping block 1 is slidably connected to the sliding groove 10, the hydraulic groove 2 is opened in the mobile clamping block 1, and multiple adjustment holes 3 are all opened on one side inner wall of the hydraulic groove 2, multiple adjustment rods 4 are respectively slidably connected to the multiple adjustment holes 3, multiple fitting blocks 5 are respectively fixedly connected to one side end of the multiple adjustment rods 4, multiple rubber pads 6 are respectively fixedly connected to one side end of the multiple fitting blocks 5, and the bottom plate 7 is fixedly connected to one side end of the mobile clamping block 1;

[0034] The battery vehicle housing 8 is arranged at the adjacent ends of the two sets of fixed components.

[0035] When the battery car parts are fixed, the driving assembly drives the two fixing assemblies to clamp toward the middle. When the battery car shell 8 with irregular sides is encountered, the rubber pad 6 contacts the battery car shell 8. When the rubber pad 6 of the rubber material clamps the battery car shell 8, the battery car shell 8 does not move. The protruding part of the battery car shell 8 squeezes the fitting block 5 to make the adjusting rod 4 slide into the hydraulic groove 2. The hydraulic oil is extremely difficult to be squeezed and contracted. Therefore, when one adjusting rod 4 is squeezed to slide into the hydraulic groove 2, the remaining adjusting rods 4 will be squeezed to slide outward until multiple rubber pads 6 contact one side end of the battery car shell 8 and are fixed by clamping the fitting blocks 5 and rubber pads 6 on both sides. By sliding and adjusting multiple fitting blocks 5 and rubber pads 6, the side edges of the irregular battery car shell 8 are fitted and fixed, so that the device can fix battery car shells of different shapes.

[0036] For details, please refer to Figure 1-Figure 5 The lower inner wall of the fixed base 20 is fixedly connected with a rotating sleeve 9, and a bidirectional screw 11 is rotatably connected inside the rotating sleeve 9. The lower end of the movable clamping block 1 is fixedly connected with two movable blocks 12. One side end of the two movable blocks 12 is provided with a threaded hole 13, and the two threaded holes 13 are threadedly connected to the bidirectional screw 11.

[0037] In this embodiment: the rotating sleeve 9 supports one side end of the bidirectional screw 11, the thread directions on both sides of the bidirectional screw 11 are opposite, and the two moving blocks 12 are respectively mounted on the opposite threads on both sides, and the moving blocks 12 are limited and cannot rotate. When the driving assembly drives the bidirectional screw 11 to rotate, the moving blocks 12 on both sides slide toward the adjacent ends to clamp and fix the moving blocks 12.

[0038] For details, please refer to Figure 1-Figure 5The lower inner wall of the fixed base 20 is fixedly connected to the driving motor 17 , and one side end of the bidirectional screw 11 is fixed to the output end of the driving motor 17 .

[0039] In this embodiment, the output end of the driving motor 17 is connected to the other side end of the bidirectional screw 11 , and the driving motor 17 drives the bidirectional screw 11 to rotate in the rotating sleeve 9 to drive the two movable clamping blocks 1 to move and clamp the battery vehicle housing 8 .

[0040] For details, please refer to Figure 1-Figure 5 Two limiting slide rods 14 are provided on one side end of each moving block 12, and a plurality of supporting bases 15 are fixedly connected to the lower inner wall of the fixed base 20. The side ends of the plurality of supporting bases 15 are fixedly connected to two limiting rods 16, and the plurality of limiting slide rods 14 slide on the circumferential surfaces of the two limiting rods 16 respectively.

[0041] In this embodiment: multiple support bases 15 provide support for two limit rods 16 respectively, and the moving block 12 slides on the surface of the two limit rods 16 through the limit sliding rods 14 opened at both ends, so that the moving block 12 will not be offset when sliding, and then the bidirectional screw 11 drives the moving clamping block 1 to move when rotating.

[0042] For details, please refer to Figure 1-Figure 5 The upper end of the fixed base 20 is fixedly connected with the partition 18.

[0043] In this embodiment, the partition 18 is provided in the middle of the fixed base 20. When the battery vehicle housing 8 is being painted, the partition 18 blocks the paint from the fixed base 20 at the lower end, thus preventing the device from being contaminated by the paint.

[0044] For details, please refer to Figure 1-Figure 5 Two moving grooves 19 are provided at the upper end of the partition 18 .

[0045] In this embodiment, the moving groove 19 is provided at the upper end of the sliding groove 10 to provide a sliding space for the moving clamping block 1 .

[0046] It should be noted that the driving motor 17 used in this device is prior art and will not be described in detail here.

[0047] When the battery car parts are fixed, the driving assembly drives the two fixing assemblies to clamp toward the middle. When the battery car shell 8 with irregular side is encountered, the rubber pad 6 contacts the battery car shell 8. When the rubber pad 6 of the rubber material clamps the battery car shell 8, the battery car shell 8 does not move. The protruding part of the battery car shell 8 squeezes the fitting block 5 to make the adjusting rod 4 slide into the hydraulic groove 2. The hydraulic oil is extremely difficult to be squeezed and contracted. Therefore, when one adjusting rod 4 is squeezed to slide into the hydraulic groove 2, the remaining adjusting rods 4 will be squeezed to slide outward until multiple rubber pads 6 all contact one side end of the battery car shell 8, and the battery car shell 8 is fixed by clamping the fitting blocks 5 and rubber pads 6 on both sides. By sliding and adjusting multiple fitting blocks 5 and rubber pads 6, the side edges of the irregular battery car shell 8 are fitted and fixed, so that the device can fix battery car shells of different shapes.

[0048] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
