[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Please see Figure 1-4This utility model provides an embodiment of a robotic arm's guiding and moving mechanism, including a support mounting frame 1. A stable base 2 is provided at the lower end of the support mounting frame 1, and a reinforcing support plate 3 is provided at the upper end of the stable base 2. A guiding device 4 is mounted on one side of the support mounting frame 1. Six fixing screw holes 401 are provided inside the rear end of the guiding device 4, symmetrically arranged about the vertical center line of the guiding device 4. A fixing frame 5 is mounted on one side of the guiding device 4. A rotating lead screw 9 is installed inside the guiding device 4. A lead screw slide 10 is mounted on one end of the rotating lead screw 9. A connecting seat 11 is mounted on one side of the lead screw slide 10. One end of the connecting seat 11 is fixedly connected to the lead screw slide 10 by a fixing screw 12. A limiting mounting groove 1101 is provided inside one end of the seat 11. A support mounting seat 13 is installed on one side of the connecting seat 11. The support mounting seat 13 includes a support seat 14 and a fixed seat 15. The fixed seat 15 is provided at one end of the support seat 14. The moving mechanism can be supported and installed through the support mounting frame 1. The installed robot can be easily guided through the guide device 4, so that the robot can work more efficiently. When the rotating screw 9 is rotated through the screw slide 10, the screw slide 10 can move along the direction of the rotating screw 9, thereby driving the robot to move. It should be noted that, in order to save space and highlight the innovative elements of this patent, such as the working principle and working process of how the robot works, it will not be described in detail in this patent.

[0019] See Figure 1 There are two stabilizing bases 2, which are symmetrical about the vertical center line of the support mounting frame 1. The support mounting frame 1 and the stabilizing base 2 are an integral structure. The reinforcing support plate 3 is located at both ends of the support mounting frame 1. One end of the reinforcing support plate 3 is welded to the support mounting frame 1, and the lower end of the reinforcing support plate 3 is welded to the stabilizing base 2. The stabilizing base 2 can improve the stability of the moving mechanism and prevent the moving mechanism from tipping over during operation. The reinforcing support plate 3 can improve the structural strength between the stabilizing base 2 and the support mounting frame 1, and at the same time provide support between the stabilizing base 2 and the support mounting frame 1.

[0020] See Figure 1 , Figure 2 and Figure 3 A lead screw motor 6 is installed on one side of the fixed frame 5. The fixed frame 5 and the guide device 4 are fixedly connected by connecting screws 7. The rotating lead screw 9 and the output end of the lead screw motor 6 are fixedly connected by a coupling 8. The lead screw motor 6 enables the rotating lead screw 9 to rotate, thereby enabling the moving mechanism to drive the robot to move. The coupling 8 connects the rotating lead screw 9 and the output end of the lead screw motor 6, thus providing good protection between the rotating lead screw 9 and the output end of the lead screw motor 6.

[0021] See Figure 1 , Figure 2 and Figure 4 The support base 14 and the fixed base 15 are integrated structures. The support base 14 has four mounting screw holes 1401 inside. One end of the fixed base 15 is provided with a limiting mounting slider 1501, which is integrated with the fixed base 15. The limiting mounting slider 1501 is correspondingly set with the limiting mounting groove 1101 and is located inside the limiting mounting groove 1101. The fixed base 15 and the limiting mounting groove 1101 are fixedly connected by mounting screws 16. By installing the limiting mounting slider 1501 into the limiting mounting groove 1101, the fixed base 15 and the connecting base 11 can be effectively limited and fixed. Then, the mounting screws 16 are used for installation and fixation, which makes the installation of the fixed base 15 and the connecting base 11 more secure.

[0022] Working principle: In use, the robot arm is installed on the support base 14 above the support mounting base 13. When the robot arm needs to move during operation, the lead screw motor 6 is turned on, which causes the coupling 8 to rotate the lead screw 9. This causes the lead screw slide 10 to move along the direction of the rotating lead screw 9, allowing the robot arm to move with the guide device. This improves the robot arm's performance. The guide device 4 can be installed on the support mounting bracket 1, making it easy to install and guide the robot arm.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
