[0031] 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.

[0032] like Figures 1 to 4 As shown, a non-standard device for assembling electric drive assemblies of new energy vehicles with a precise positioning function includes a working compartment 1 on which a transmission component 2 is provided;

[0033] The transmission assembly 2 includes a fixed plate 21, a first rotating shaft 212 is rotatably connected to the bottom of the fixed plate 21, the first rotating shaft 212 is rotatably connected to the working chamber 1, a pneumatic telescopic rod 211 is fixedly connected to the bottom of the fixed plate 21, a rotating rod 22 is slidably connected to the fixed plate 21, an arcuate slide rail 23 is slidably connected to the rotating rod 22, the arcuate slide rail 23 is fixedly connected to the working chamber 1, a first sliding block 24 is slidably connected to the working chamber 1, a sliding groove is provided on the first sliding block 24, a first electric telescopic rod 25 is fixedly connected to the first sliding block 24, and the first electric telescopic rod 25 is fixedly connected to the working chamber 1;

[0034] The bottom of the working chamber 1 is threadedly connected to a screw rod 4, a connecting block 42 is provided on the screw rod 4, and a hydraulic assembly claw 43 is fixedly connected to the connecting block 42;

[0035] In the present invention, the second electric telescopic rod 31 is activated, serving as a power source, and drives the rotating rod 22 to slide on the arc-shaped slide rail 23 via the second sliding block 26. This action causes the second electric telescopic rod 31 to rotate on the second rotating shaft 3, thereby pulling the corner of the fixed plate 21 connected to the rotating rod 22. The other side of the fixed plate 21 drives the first rotating shaft 212 to slide within the guide groove of the working chamber 1, causing the fixed plate 21 to drive the first mounting plate 27 to stand vertically, and the pneumatic telescopic rod 211 on the fixed plate 21 slides into the first sliding block 24. Under the guidance of the laser calibrator, the first electric telescopic rod 25 is controlled to extend and retract. The telescopic movement of the first electric telescopic rod 25 drives the first sliding block 24 to slide on the working chamber 1, so that the fixed plate 21 slides horizontally on the rotating rod 22, and is adjusted from the initial horizontal placement to vertical erection. Accurate position calibration can be performed in the horizontal direction, thereby realizing precise control and adjustment of the position and posture of the fixed plate 21. This precise mechanical movement can ensure that the parts to be installed maintain an accurate position during the assembly process, further ensuring the accuracy of the assembly, and solving the problem in the background technology that manual measurement is required after replacing parts of different specifications, resulting in large errors.

[0036] Further, such as Figures 1 to 4 As shown, the screw rod 4 is fixedly connected to the motor 41, and the motor 41 is fixedly connected to the working chamber 1. The first mounting plate 27 is fixedly connected to the fixing plate 21, and a mounting port is opened on the fixing plate 21. The second mounting plate 28 is slidably connected to the mounting port on the fixing plate 21. The second mounting plate 28 is rotatably connected to the threaded rod 210, and both ends of the threaded rod 210 are threadedly connected to the rotating disk 29.

The laser sensor can be installed on the second mounting plate 28. The second mounting plate 28 is moved by external force to contact the first mounting plate 27, and then the two rotating disks 29 are twisted by external force to fix the second mounting plate 28. The second mounting plate 28 can be fixed, and the installation of the laser sensor is completed, which is convenient for adjusting the position of the laser sensor according to actual conditions.

[0037] The pneumatic telescopic rod 211 is slidably connected to the working chamber 1. When the fixing plate 21 slides in the working chamber 1, the pneumatic telescopic rod 211 is driven to slide in the working chamber 1, and finally the pneumatic telescopic rod 211 slides onto the first sliding block 24, thereby fixing and flipping the first mounting plate 27 and turning the component over.

[0038] A connecting plate 11 is fixedly connected in the working chamber 1, and a guide groove is provided on the connecting plate 11. The first rotating shaft 212 is slidably connected in the guide groove on the connecting plate 11. A third sliding block 44 is slidably connected in the guide groove on the connecting plate 11. The third sliding block 44 is threadedly connected to the screw rod 4. The connecting block 42 is fixedly connected to the third sliding block 44. The third sliding block 44 is slidably connected in the working chamber 1. By providing the guide groove, the third sliding block 44 is guided during use to prevent it from rotating.

[0039] A sliding opening is provided on the working compartment 1, and the first electric telescopic rod 25 is fixedly connected to the sliding opening on the working compartment 1. The first sliding block 24 is slidably connected to the sliding opening on the working compartment 1. A sliding groove is provided on the first sliding block 24. By providing a sliding opening on the working compartment 1, the first electric telescopic rod 25 is conveniently connected. The controllability of the first electric telescopic rod 25 is high, thereby improving the degree of automation of the device.

[0040] The above solution still has the problem of how to transmit the rotating rod 22. Figure 1 、 Figure 2 As shown, both ends of the rotating rod 22 are fixedly connected to the second sliding block 26, and the second first electric telescopic rod 25 is fixedly connected to the second sliding block 26. The end of the second first electric telescopic rod 25 away from the second sliding block 26 is fixedly connected to the second rotating shaft 3, and the second rotating shaft 3 is rotatably connected to the working bin 1. When in use, the second rotating shaft 3 can be set. When in use, by starting the second first electric telescopic rod 25, the second first electric telescopic rod 25 drives the rotating rod 22 to slide on the arc slide rail 23, thereby realizing transmission to the first mounting plate 27.

[0041] Working principle: Figures 1 to 4 As shown, when in use, first place the part to be mounted on the first mounting plate 27 and fix it, then move the second mounting plate 28 to make it rest against the part to be mounted, turn the rotating disk 29 to limit the position of the second mounting plate 28, and then install the laser aligner on the second mounting plate 28;

[0042] The second electric telescopic rod 31 is activated. The second electric telescopic rod 31 drives the rotating rod 22 to slide on the arc-shaped slide rail 23 via the second sliding block 26. The second electric telescopic rod 31 rotates on the second rotating shaft 3. At this time, the corner of the fixed plate 21 connected to the rotating rod 22 is pulled up, and the other side drives the first rotating shaft 212 to slide in the guide groove on the working chamber 1, so that the fixed plate 21 drives the first mounting plate 27 to stand vertically.

[0043] At this time, the pneumatic telescopic rod 211 on the fixed plate 21 slides into the first sliding block 24. Under the action of the laser calibrator, the first electric telescopic rod 25 is controlled to extend and retract, driving the first sliding block 24 to slide on the working chamber 1, so that the fixed plate 21 slides horizontally on the rotating rod 22 to adjust the position of the mounting part.

[0044] Afterwards, the motor 41 is started to rotate the electric screw 4, so that the third sliding block 44 and the connecting block 42 slide on the working chamber 1, so that the hydraulic assembly claw 43 contacts the part to be installed, and the installation part is installed. During the installation process, the laser calibrator can also play a calibration role, and timely control the first electric telescopic rod 25 to respond.
