Detailed Embodiment

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0028] Embodiment:

[0029] Please refer to Figures 1-5As shown in the figure, a fixture for the lower box body of a battery box according to the present utility model includes a frame 1. A first calibration tooling 2 and a second calibration tooling 3 are arranged on the frame 1. A detector 4 performs zero-degree calibration on the first calibration tooling 2 and the second calibration tooling 3. The zero-degree calibration points of the first calibration tooling 2 and the second calibration tooling 3 are different. A number of test holes for the detector 4 to detect are provided around the edge of the lower box body 10 of the battery box;

[0030] In the middle of the tabletop of the frame 1, there is a detection area. During assembly, the lower box body 10 of the battery box is placed in the detection area and horizontally pressed by a number of horizontal pressing toolings 5 on the edge. There are also an even number of symmetrically arranged diagonal pressing toolings 11 for pressing in the slope direction. Above the detection area, there is at least one set of detection tooling 9. In the drawings, we have drawn two sets of parallel detection tooling 9. Among them, the detection tooling 9 is supported above the moving tooling 8 and driven to move by the moving tooling 8. The detection tooling 9 includes a cross beam 91. In the middle of the cross beam 91, there is a slide rail. One or more detection plates 93 that can slide along the cross beam 91 are sleeved on the slide rail. At the bottom of the detection plate 93, there is a convex block 932. The convex block 932 is provided with a matching groove 933 towards the middle of the detection plate 93. On both sides of the matching groove 933, there are arc-shaped openings for detection. At the same time, in order to reduce the weight when the detection plate 93 is pushed, a number of empty slots 931 are provided in the middle of the detection plate 93. In order to facilitate the cross beam 91 to better leave the upper surface of the moving tooling 8, handles 92 are provided on both sides of the top of the cross beam 91;

[0031] In order to facilitate the movement of the frame 1, the frame 1 is arranged on moving wheels 13. A brake pad is provided on the outside of the moving wheels 13. A support column 12 is arranged in the inward direction of the moving wheels 13. The support column 12 is arranged at the bottom of the frame 1. In actual use, we will set the support column 12 as a liftable support column, and adjust the lift of the frame tabletop through a threaded matching method to facilitate the operation of workers;

[0032] To facilitate the realization of limited displacement, we set the moving tooling as follows: The moving tooling 8 includes a plug-in block 82 arranged below the cross beam 91. A groove for matching with the cross beam 91 is provided in the middle of the plug-in block 82. The plug-in block 82 is arranged on a support column 81, and the support column 91 is arranged on a moving base 83. The moving base 83 is arranged on the periphery of the detection area. A slider 84 is provided at the bottom of the moving base 83, and the slider 84 is arranged to match with the guide rail 6. A limit block 7 is fixedly installed at the moving front end of the guide rail 6. When the moving base 83 moves to a specific position, it is locked by a set screw 85 at the side. The front end of the limited displacement of the moving tooling 8 is the limit block 7, that is, the detection area is at the position between the rear end and the limit block 7 (the texture of this linear distance is consistent). If the detection tooling does not deviate and there is no jamming during the entire pushing process, it means that the lower box body 10 of the battery box is within the error range and passes the detection.

[0033] When the present utility model is in use, a first calibration tooling and a second calibration tooling are arranged above the machine frame to calibrate two detection zero-degree values of the detector. A processing area is arranged above the machine frame. When detecting, the lower box body of the battery box is placed in the detection area, and then the horizontal pressing tooling and the oblique pressing tooling arranged outside the processing area are used to respectively fix the horizontal side and the slope side of the lower box body of the battery box. It should be noted that the above-mentioned first calibration tooling, second calibration tooling, horizontal pressing tooling and oblique pressing tooling are all structures that can be purchased in the prior art, and this solution will not be described in detail. After the lower box body of the battery box is installed, the calibrated detector is used to detect the outer side of the lower box body of the battery box one by one. This part of the detection is performed manually, and the detection is carried out at the test hole positions set on the side of the lower box body of the battery box, making the manual detection of points more accurate. The detection of the inner curved surface and texture of the lower box body of the battery box is realized by the detection tooling arranged above the detection area. The detection tooling is mounted above the moving tooling. By moving the detection plate on the detection tooling, the detection plate slides on the chute and is fixed with screws after sliding. The convex blocks and matching grooves on the detection plate respectively cooperate with the textures on the lower box body of the battery box. Then, the slider of the moving tooling drives the moving base and drives the support column to move. During the moving process, the slider moves on the guide rail, and a limit block is arranged at the front end of the guide rail and fixed. In this way, if there is no jamming or deviation when the detection plate moves to the position of the limit block, it means that the product is within the error range and is a qualified product. In actual use, the two moving bases on both sides of the detection tooling can also be evenly pushed by a cylinder or an external pushing device. If positioning detection is required, the moving base can be locked by a set screw. It should be noted that in actual use, there is more than one set of mutually parallel detection toolings arranged above the detection area, such as Figures 1-2As shown, in actual use, the position of the detection plate on the cross beam can be adjusted according to the protrusion and bending amplitude of the lower box body of the battery box, and the number and size of the plates can also be adjusted, with strong adaptability and better matching of the lower box body of the battery box to be detected.

[0034] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
