At the same time, it can also assist personnel in disassembling the instrument panel and play a certain positioning role. In the process of controlling the movement of the fixing mechanism 12, the storage mechanism 11 will be driven to move. At this time, the personnel can store the important parts removed during the verification process, thereby preventing the parts from being lost. After the fixation is completed, the personnel can calibrate the instrument panel pointer. After the verification is completed, the auxiliary mechanism 10 can be controlled to move. At this time, the test line 13 is removed from the auxiliary mechanism 10, and the instrument panel is powered on to check again whether the instrument panel is used normally.

[0023] like Figure 3 , Figure 4 , Figure 5As shown, the fixing mechanism 12 includes a transmission motor 1201, a transmission worm 1202, a worm wheel 1203, a transmission bidirectional screw 1204, a clamping plate 1205, a rubber pad 1206, a return spring 1207 and a guide rod 1208.

[0024] After the personnel places the instrument panel on the placement plate 3, the transmission motor 1201 can be controlled to rotate. When the transmission motor 1201 rotates, it will drive the transmission worm 1202 to rotate. At the same time, the transmission worm 1202 will drive the transmission bidirectional screw 1204 to rotate through the worm gear 1203. At this time, the transmission bidirectional screw 1204 will drive the clamping plate 1205 and the rubber pad 1206 to clamp and fix the instrument panel. The rubber pad 1206, the return spring 1207 and the guide rod 1208 can prevent the clamping plate 1205 from causing damage to the surface of the instrument panel during the clamping process. At the same time, when the personnel disassemble and replace the instrument panel pointer, it can prevent the instrument panel from falling and being damaged due to excessive force, thereby reducing unnecessary losses. At the same time, it can also assist personnel in disassembling the instrument panel, play a certain positioning role, and improve the work efficiency of personnel.

[0025] like Figure 4 , Figure 5 , Figure 7As shown, the storage mechanism 11 includes a storage column 1101, an extension column 1102, a storage box 1103, a second return spring 1104, a transmission tooth plate 1105, a gear 1106, a transmission rod 1107, a lifting rod 1108 and a telescopic rod 1109, the extension column 1102 is movably connected to the inside of the storage column 1101, a storage groove is provided on one side of the extension column 1102, and the storage box 1103 is movably connected to the inside of the storage groove, one end of the second return spring 1104 is fixedly connected to the inner wall of the storage groove, and the other end of the second return spring 1104 is fixedly connected to the bottom end of the storage box 1103, the transmission rod 1107 is rotatably connected to the inside of the storage column 1101, and one end of the transmission rod 1107 extends to On the outside of the storage column 1101, the gear 1106 is fixedly connected to one end of the transmission rod 1107, and the transmission tooth plate 1105 is movably connected to the top of the gear 1106, the transmission tooth plate 1105 is meshed with the gear 1106, one end of the transmission tooth plate 1105 is fixedly connected to the outer wall of the splint 1205, the top end of the lifting rod 1108 is hinged to one side of the bottom end of the extension column 1102, and the other end of the lifting rod 1108 is fixedly connected to the outer wall of the transmission rod 1107, the top end of the telescopic rod 1109 is fixedly connected to the other side of the bottom end of the extension column 1102, and the bottom end of the telescopic rod 1109 is fixedly connected to the inner bottom end of the storage column 1101, and the storage column 1101 is respectively fixedly connected to both sides of the storage plate 7.

[0026] When the clamping plate 1205 clamps the instrument panel, the transmission gear plate 1105 is driven to move, and the transmission gear plate 1105 moves to drive the gear 1106 to rotate, so that the lifting rod 1108 is driven by the gear 1106 to push the extension column 1102 out of the storage column 1101. After the extension column 1102 is pushed out, the return spring 1104 pushes the storage box 1103 to protrude from the outside of the extension column 1102. At this time, the personnel can store the disassembled important parts into the storage box 1101. 03, after the clamp is released, because the bottom end of the extension column 1102 and the inner side of the top end of the storage column 1101 are set at 45°, the storage box 1103 will be stored in the storage slot when the extension column 1102 descends, and the important components such as the instrument panel pointer removed by the personnel can be stored through the storage box 1103, so as to prevent the loss during subsequent use, reduce the inconvenience caused to the personnel, and prevent the situation that the personnel accidentally touch the important parts during the operation and cause damage.

[0027] like Figure 6 , Figure 8As shown, the auxiliary mechanism 10 includes an electric push rod 1001, a transmission seat 1002, a connecting rod 1003, a slider 1004, a parallel slide rail 1005, an opening and closing plate 1006, a clamping block 1007 and a reset spring three 1008. The transmission seat 1002 is provided with two upper and lower symmetrical ones, and the output ends of the electric push rod 1001 are fixedly connected to the inside of the transmission seat 1002. The connecting rod 1003 is provided with two groups of left and right symmetrical ones, one end of the connecting rod 1003 is respectively hinged to one side of the transmission seat 1002, and the other end of the connecting rod 1003 is respectively hinged to the top of the opening and closing plate 1006, one end of the reset spring three 1008 is fixedly connected to the outer wall of the opening and closing plate 1006, and the reset spring three 1008 The other end is fixedly connected to the inner wall of the auxiliary plate 5, and the opening and closing plate 1006 is provided with two groups symmetrically arranged in upper and lower parts. The rear side of the clamping block 1007 is fixedly connected to the inner wall of the auxiliary plate 5, and the rear side of the opening and closing plate 1006 is fixedly connected to the outer wall of the slider 1004, and the slider 1004 is slidably connected to the outer wall of the parallel slide rail 1005, and the parallel slide rail 1005 is fixedly connected to the inside of the slide groove 6, and the rear side of the transmission seat 1002 is slidably connected to the inside of the slide groove 6. The inside of the clamping block 1007 is movably connected with the test line 13, and one side of the opening and closing plate 1006 is movably connected to the outer wall of the clamping block 1007, and the electric push rod 1001 is fixedly connected to the top of the auxiliary plate 5, and the output end of the electric push rod 1001 extends to the inside of the auxiliary plate 5.

[0028] After the instrument panel is checked, the fixing mechanism 12 can be controlled to release the limit, and the important components can be taken out from the storage mechanism 11 and assembled on the instrument panel. At this time, the electric push rod 1001 can be controlled to extend. During the extension process, the transmission seat 1002 and the connecting rod 1003 will push the opening and closing plates 1006 on both sides to move on the parallel slide rails 1005. At this time, the opening and closing plates 1006 will be away from the clamping block 1007. Thereafter, the personnel can take out the test line 13 and connect it to the instrument panel for power supply inspection to check whether the pointer is operating normally. The instrument panel test line 13 can be regularized through the auxiliary mechanism 10 to prevent the test lines 13 from being entangled, so as to reduce the inconvenience caused by personnel when testing the instrument panel wiring. At the same time, it can also prevent the test line 13 from being entangled and damaged to cause a short circuit, thereby improving safety.

[0029] Here’s how it works: When in use, first, after placing the instrument panel on the placement plate 3, the transmission motor 1201 can be controlled to rotate. When the transmission motor 1201 rotates, it will drive the transmission worm 1202 to rotate. At the same time, the transmission worm 1202 will drive the transmission bidirectional screw 1204 to rotate through the worm gear 1203. At this time, the transmission bidirectional screw 1204 will drive the clamping plate 1205 and the rubber pad 1206 to clamp and fix the instrument panel. The rubber pad 1206, the return spring 1207 and the guide rod 1208 can prevent the clamping plate from rotating. In order to prevent the surface of the instrument panel from being damaged during the clamping process of 1205, and to prevent the instrument panel from being damaged due to excessive force when personnel disassemble and replace the instrument panel pointer, the clamping plate 1205 will drive the transmission gear plate 1105 to move during the clamping process of the instrument panel, and the transmission gear plate 1105 will drive the gear 1106 to rotate when the transmission gear plate 1105 moves, so that the lifting rod 1108 is driven by the gear 1106 to push the extension column 1102 out of the storage column 1101. After the extension column 1102 comes out, the return spring 1104 will push the storage box 1103 to extend out of the extension column 1102. At this time, the personnel can store the disassembled important parts into the storage box 1103. After the clamp is released, because the bottom end of the extension column 1102 and the inner side of the top end of the storage column 1101 are set at 45 degrees, when the extension column 1102 descends, the storage box 1103 will be stored in the storage slot, which can prevent the personnel from accidentally touching the important parts during the operation and causing damage. After that, the fixing mechanism 12 can be controlled to release the limit, and the important components can be taken out from the storage mechanism 11 and assembled on the instrument panel. At this time, the electric push rod 1001 can be controlled to extend. During the extension process, the opening and closing plates 1006 on both sides will be pushed to move on the parallel slide rails 1005 through the transmission seat 1002 and the connecting rod 1003. At this time, the opening and closing plates 1006 will move away from the clamping block 1007. After that, the personnel can take out the test line 13 and connect it to the instrument panel to check the power supply and whether the pointer is operating normally.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
