[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0023] Please refer to Figs. 1 to 3 The utility model provides a kind of technical scheme: a big quality finished part assembly work is assisted with power mechanical arm, including base 1, mechanical arm 2 and interactive panel 3, the inside of base 1 is equipped with the adjusting structure for adjusting the angle position of mechanical arm 2.

[0024] As Fig. 1 As shown, adjusting structure includes motor 4 fixedly connected to the inner bottom wall of base 1, connecting rod 5 fixedly connected to the output shaft of motor 4, speed reducer 6 fixedly connected to the right end of connecting rod 5, transmission rod 7 fixedly connected to the power transmission end of speed reducer 6, transmission gear 8 fixedly connected to the right end of transmission rod 7, driven gear 9 engaged on the top of transmission gear 8, support rod 10 fixedly connected to the inner side of the center of driven gear 9 and support assembly arranged at the top end of support rod 10.

[0025] It should be noted that the right end of connecting rod 5 is fixedly connected with the power input end of speed reducer 6, and speed reducer 6 is fixedly connected to the inner bottom wall of base 1. This design ensures that the power output by motor 4 can be stably and efficiently transmitted to speed reducer 6, and the fixed connection of speed reducer 6 ensures the stability and reliability during power transmission, providing a solid foundation for subsequent angle adjustment.

[0026] Transmission gear 8 and driven gear 9 are both conical gears, and the bottom end of support rod 10 is rotatably connected to the inner bottom wall of base 1.

[0027] The support assembly includes bottom disc 11 fixedly connected to the top end of support rod 10, four fixed rods 12 fixedly connected to the upper surface of bottom disc 11, and top disc 13 fixedly connected between the top ends of four fixed rods 12, and mechanical arm 2 is fixedly installed on the upper surface of top disc 13. This design of support assembly provides a stable and reliable support structure that can withstand the weight of mechanical arm 2 and its load while maintaining good stability. The combination of four fixed rods 12 and top disc 13 forms a rigid frame, which helps to disperse and resist various external forces and loads.

[0028] The center of the bottom of the top disc 13 is fixedly connected with a reinforcing support rod 14, and the bottom end of the reinforcing support rod 14 is fixedly connected with the upper surface of the bottom disc 11. The addition of the reinforcing support rod 14 further enhances the rigidity of the support assembly, improves the ability to withstand heavy load and resist deformation, and helps to ensure the stability and accuracy of the mechanical arm 2 during angle adjustment.

[0029] The upper surface of the base 1 is provided with a rotating groove matched with the bottom disc 11, and the inner top wall of the base 1 is provided with a through hole matched with the support rod 10 and communicated with the rotating groove. The top end of the support rod 10 penetrates through the through hole and extends to the inner side of the rotating groove and is fixedly connected with the bottom disc 11.

[0030] The bottom of the bottom disc 11 is provided with four rolling grooves, and the inner side of each rolling groove is rolling with a ball bearing 15. The bottom of the ball bearing 15 is in contact with the inner bottom wall of the rotating groove. The design of the ball bearing 15 greatly reduces the frictional resistance between the bottom disc 11 and the inner bottom wall of the rotating groove, making the angle adjustment of the mechanical arm 2 more smooth and flexible. This design not only improves the operating efficiency of the equipment, but also prolongs the service life of the equipment.

[0031] The working principle of the above embodiment is as follows:

[0032] When the motor 4 starts, the rotating power is transmitted to the speed reducer 6 through the connecting rod 5. The speed reducer 6 reduces the rotating speed and increases the torque, ensuring the stability and reliability of power transmission. The power output end of the speed reducer 6 is fixedly connected with the transmission gear 8 through the transmission rod 7. Since the transmission gear 8 and the driven gear 9 are both conical gears and mesh with each other, when the transmission gear 8 rotates, it can drive the driven gear 9 to rotate. The support rod 10 fixedly connected with the inner side of the center of the driven gear 9 is rotatably connected with the inner bottom wall of the base 1 at the bottom end, ensuring that the driven gear 9 can drive the support rod 10, the bottom disc 11, the fixed rod 12, the top disc 13 and the mechanical arm 2 at the top end to adjust the angle as a whole when the driven gear 9 rotates.

[0033] The bottom disc 11 is fixedly connected with the top disc 13 through four fixed rods 12, forming a stable support frame. Moreover, the center of the bottom of the top disc 13 is also fixedly connected with a reinforcing support rod 14, and the bottom end of the reinforcing support rod 14 is fixedly connected with the upper surface of the bottom disc 11, thereby improving the rigidity of the support assembly and helping to disperse the pressure generated by the mechanical arm 2 and its load. In addition, the bottom of the bottom disc 11 is provided with four rolling grooves, and each rolling groove is rolling with a ball bearing 15. When the bottom disc 11 rotates in the rotating groove of the base 1, the ball bearing 15 can reduce the frictional resistance between the bottom disc 11 and the inner bottom wall of the rotating groove, making the angle adjustment of the mechanical arm 2 more smooth and flexible.
