DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0025] Please refer to Figures 1-5 The present application provides a technical solution:

[0026] A new energy automobile battery tray airtightness detection tool, comprising:

[0027] The workbench 1 is provided with the tray body 2 clamped and connected thereon, a first adjusting groove 15 is formed in the workbench 1, a first bidirectional threaded rod 16 is rotatably connected in the first adjusting groove 15, a first servo motor 17 is fixedly installed on the workbench 1, and the output end of the first servo motor 17 is connected with the extended end of the first bidirectional threaded rod 16 penetrating through the first adjusting groove 15, and first clamping plates 18 are threadedly connected at both ends of the first bidirectional threaded rod 16, a second adjusting groove 19 is formed in the workbench 1, a second bidirectional threaded rod 20 is rotatably connected in the second adjusting groove 19, a second servo motor 21 is fixedly installed on the workbench 1, and the output end of the second servo motor 21 is connected with the extended end of the second bidirectional threaded rod 20 penetrating through the second adjusting groove 19, and second clamping plates 22 are threadedly connected at both ends of the second bidirectional threaded rod 20, and rubber layers 23 are arranged on the first clamping plates 18 and the second clamping plates 22 and are in contact with the tray body 2;

[0028] The tray body 2 is placed on the workbench 1, and the first servo motor 17 is started to realize horizontal clamping:

[0029] The first servo motor 17 is started, and the output end of the motor drives the first bidirectional threaded rod 16 to rotate. Since the first clamping plates 18 are threadedly connected at both ends of the first bidirectional threaded rod 16 and the thread rotation directions are opposite, according to the screw transmission principle, with the rotation of the first bidirectional threaded rod 16, the first clamping plates 18 at both ends will move towards each other in the first adjusting groove 15. The operator closely observes the movement of the first clamping plates 18, accurately controls the motor speed through the control system, and gradually moves the first clamping plates 18 to approach one side of the tray body 2 until the rubber layer 23 lightly contacts the corresponding side edge of the tray body 2. At this time, it should be avoided that the clamping is too tight to cause deformation or damage of the tray body 2, and only the preliminary positioning and light clamping functions are needed.

[0030] The second servo motor 21 is started to realize longitudinal clamping:

[0031] After the first clamping plates 18 complete the preliminary horizontal clamping, the second servo motor 21 is started in succession, which drives the second bidirectional threaded rod 20 to rotate. According to the screw transmission characteristics, the second clamping plates 22 at both ends of the second bidirectional threaded rod 20 move towards each other in the second adjusting groove 19. Through accurate regulation and control of the second servo motor 21, the second clamping plates 22 slowly approach the other side of the tray body 2 until the rubber layer 23 is tightly attached to the tray body 2, thereby realizing stable longitudinal clamping of the tray body 2. At this time, the tray body 2 has been firmly fixed on the workbench 1 in two directions, and displacement and shaking do not occur in the subsequent detection process.

[0032] Further, the workbench 1 is fixedly provided with a mounting plate 24, and the first servo motor 17 and the second servo motor 21 are fixedly mounted on the mounting plate 24, so that the first servo motor 17 and the second servo motor 21 are conveniently mounted and fixed.

[0034] When the air tightness is detected, the connecting pipe 6 is connected with the detection pipe 8, the push handle 27 is pressed, the push handle 27 drives the clamping ring 13 to move downward through the connecting rod 26, then the clamping head 7 is connected in the connecting groove 10, when the clamping head 7 is completely clamped in the connecting groove 10, the push handle 27 is released, the reset spring 12 releases the elastic potential energy, and the clamping ring 13 is clamped in the clamping groove 14, so that the clamping head 7 is clamped and fixed in the connecting groove 10, the connecting pipe 6 and the detection pipe 8 are clamped and fixed, the connection stability between the connecting pipe 6 and the detection pipe 8 is improved, the connecting part is prevented from loosening due to the external factors such as gas impact and equipment vibration during the detection process, the detection interruption, data loss and additional time and labor cost caused by the accidental falling of the detection pipe 8 are effectively avoided, and the air tightness detection work can be smoothly completed, so that the quality control of the new energy automobile battery tray is ensured.

[0035] When the connecting pipe 6 and the detection pipe 8 are disassembled, the push handle 27 is pressed, the clamping ring 13 is moved out of the clamping groove 14, and then the clamping head 7 is taken out of the connecting groove 10.

[0036] In the above embodiment, the connecting groove 10 is provided with a rubber pad 25, the rubber pad 25 is in contact with the clamping head 7, and the rubber pad 25 can improve the sealing between the clamping head 7 and the connecting head 9.
