Therefore, in order to improve the installation efficiency and quality of the connecting shaft, it is necessary to design a quick installation fixture to assist the installation process of the connecting shaft.

[0003] The quick installation fixture can help workers install the connecting shaft quickly and accurately, reduce the time and labor intensity of manual operation, and improve production efficiency and product quality. At the same time, by rationally designing the structure and function of the fixture, it can reduce possible errors and mistakes during the installation process, ensure the installation quality and stability of the connecting shaft, and reduce quality risks and production costs.

[0004] At present, the quick installation fixture of the connecting shaft of new energy vehicles fixes the connecting shaft in the correct position through a designed clamping structure. Some fixtures may also be equipped with an automatic adjustment function. According to the assembly position requirements of the connecting shaft and other components, the fixture can automatically adjust the position and angle of the connecting shaft to ensure the accuracy and stability of the installation.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1 , Figure 2 and Figure 4 The inner wall of the base 1 is rotatably connected to a threaded rod b13, and a knob 16 is fixedly connected to the end of the threaded rod b13. Turning the knob 16 can drive the threaded rod b13 to rotate. The outer wall of the threaded rod b13 is threadedly connected to two groups of threaded sleeves 14. The inner walls of the two groups of threaded sleeves 14 are set to reverse threads, and they move closer to each other and separate due to the rotation of the threaded rod b13. The side walls of the two groups of threaded sleeves 14 are hinged with brackets 15. When the position of the threaded rod b13 changes, the angle of the bracket 15 will change. The top end of the bracket 15 is hinged to the bottom end of the support frame 2. The angle change of the bracket 15 will drive the support frame 2 to rise or fall, changing the overall height of the device, and the accuracy is high, so it can be installed more accurately.

[0033] Working principle: Place the connecting pipe between the two groups of clamping blocks 7, drive the motor 5 to rotate the threaded rod a6, so that the two groups of clamping blocks 7 are close to each other along the guide rod 8 to fix the connecting pipe, and then adjust the angle and height of the connecting pipe. When adjusting the angle of the clamping mechanism, pull the pull rod 10 outward to stretch the reset spring 9 to move outward until the limit block 11 is pulled out of the limit groove 12 and released from the clamping, and then rotate the pull rod 10 to rotate the rotating shaft 3, thereby driving the frame 4 and the clamping mechanism to change the angle. After the adjustment is completed, release the pull rod 10, and the reset spring 9 pulls the pull rod 10 back to its original position, so that the limit block 11 is re-engaged in the limit groove 12 to fix the angle. When the overall height of the device needs to be adjusted, turn the knob 16 to rotate the threaded rod b13, so that the two groups of threaded sleeves 14 are close to or separated from each other, thereby changing the angle of the bracket 15, driving the support frame 2 to slide along the inner wall of the base 1, and adjusting the overall height of the device with high precision, so that the connecting pipe can be installed in the specified position more accurately.
