[0041] Example 1, please refer to Figure 1 and Figure 2 As shown, this embodiment provides a process screw tooling for debugging an FDS process robot, including a connecting seat 1, a compression mechanism 2 is slidably sleeved in the connecting seat 1, and a process screw 3 is threadedly connected to the inside of the compression mechanism 2.

[0042] Specifically, see Figure 3 and Figure 4 As shown, the connecting seat 1 is a circular ring structure, with a circular through hole 11 in the center, an annular flange 12 in the outer ring, and a plurality of circular magnet mounting holes 13 on the flange 12. In this embodiment, three magnet mounting holes 13 are provided, and each magnet mounting hole 13 is connected with a magnet 14 by interference fit for magnetic attraction on the working area of ​​the FDS process robot.

[0043] The flange 12 is also threadedly connected with a ruler 15 , which is a rod-shaped structure with scales and is used to measure the compression amount of the compression mechanism 2 .

[0044] See also Figure 3 and Figure 5As shown, the compression mechanism 2 includes a support 21 and a spring 22. The support 21 is a cylindrical structure with a threaded hole 211 in the center. An annular boss 212 is provided at one end of the support 21. The spring 22 is sleeved on the outside of the support 21 and stopped on the boss 212. The other end of the support 21 is slidably sleeved in the through hole 11 of the connecting seat 1. The free end of the spring 22 contacts the bottom surface of the connecting seat 1 and stops on the bottom surface of the connecting seat 1.

[0045] See also Figure 3 and Figure 6 As shown, the process screw 3 includes a screw rod 31 and a nut 32 matching the screw rod 31 . The screw rod 31 is provided with threads, the head of the screw rod 31 is threadedly connected to the nut 32 , and the middle part is threadedly connected to the threaded hole 211 of the support 21 .

[0046] The top of the head of the screw 31 is provided with a hexagonal groove, and a hexagonal wrench can be used to insert the hexagonal groove to rotate the screw 31. A groove of other shapes such as a cross or a straight shape can also be provided, and the screw 31 can be rotated using a corresponding wrench or screwdriver.

[0047] The tail of the screw rod 31 extends out of the threaded hole 211 , the outer ring diameter of the nut 32 is larger than the diameter of the through hole 11 , and the nut 32 is arranged above the top surface of the connecting seat 1 and contacts the top surface of the connecting seat 1 .

[0048] The top surface of the connecting seat 1 is also provided with an annular flange 16 , and the nut 32 is sleeved inside the flange 16 .

[0049] When in use, first adjust the extended length of the screw 31 to the test length, and magnetically mount the tooling on the front end of the FDS process robot through the magnet 14 on the base 1; then the FDS process robot operates outside the workpiece to be processed according to the trial comparison program; the screw 31 is used to specify the process point during the debugging process. When the trial comparison program runs normally and the trial comparison point is accurate, a gap is left between the tail of the screw 31 and the surface of the workpiece and the screw 31 does not contact the workpiece. When the trial comparison program deviates from the actual situation, the tail of the screw 31 contacts the workpiece, driving the compression mechanism 2 to be compressed. The compression amount can be read through the ruler 15 for subsequent program modifications; for self-tapping screws of different length specifications, the screw 31 can be rotated by an Allen wrench to adjust the extended length of the screw 31.

[0050] The tooling provided in this embodiment is easy to install and simple to manufacture, and can adjust the length of the process screws. It is suitable for the program calibration process of self-tapping screws of different length specifications. The compression mechanism can ensure that the process screws do not cause serious damage to the workpiece when the robot continues to run after the process screws contact the workpiece. At the same time, the compression amount of the compression mechanism can be read, thereby facilitating the adjustment of the program and making the robot program calibration faster and more accurate.
