The bottoms of the four torsion spring members 916 are respectively fixedly connected to the tops of the four fixed pieces. The tops of the four torsion spring members 916 are all fixedly connected to the bottom of the positioning frame 901. And one end of the target plate connecting rod 10 is located inside the positioning frame 901. A fixed frame 903 is fixedly connected to the positioning frame 901. A connecting rod push block 925 is movably connected to the fixed frame 903. One side outer wall of the connecting rod push block 925 is in contact with one end of the target plate connecting rod 10. Two pressure spring rods 906 are fixedly connected to one side inner wall of the fixed frame 903. One ends of the two pressure spring rods 906 are both fixedly connected to the other side outer wall of the connecting rod push block 925. Two fixed toothed plates 905 are fixedly connected to the connecting rod push block 925. The two fixed toothed plates 905 are both located outside the fixed frame 903. A guide rail plate frame 908 is fixedly connected to one side outer wall of the positioning frame 901. Two movable toothed plates 926 are movably connected to the guide rail plate frame 908. One ends of the two movable toothed plates 926 are both fixedly connected with a push plate frame 904. A plurality of telescopic springs 929 are arranged on the opposite side outer walls of the two push plate frames 904. One ends of the plurality of telescopic springs 929 on the same side are all fixedly connected with the same positioning push plate 902. The two positioning push plates 902 are respectively in contact with both sides of the shooting target plate 11;On one side outer wall of the guide rail plate frame 908, four mounting support plates 907 are fixedly connected. Two linkage gear teeth 927 are arranged on each of the two mounting support plates 907 on the same side. Grooves are formed on all four linkage gear teeth 927. On the inner walls of the two grooves on the same side, the same transmission belt 928 is provided. The four linkage gear teeth 927 are respectively meshed with two fixed toothed plates 905 and two movable toothed plates 926. And on both inner walls of the connecting rod support 6, the same fixed frame 14 is fixedly connected. An electric push rod 13 is fixedly connected to the fixed frame 14. The output end of the electric push rod 13 is fixedly connected with a pushing plate 12. The pushing plate 12 is in contact with the other end of the target plate connecting rod 10.;

[0040] Specifically, during positioning, the electric push rod 13 drives the pushing plate 12 to push the target plate connecting rod 10, so that one end of the target plate connecting rod 10 enters the positioning frame 901. During this process, the driving motor 923 operates and drives the cable reel 922 to rotate to wind up the connecting cable 921. Further, the connecting cable 921 pulls the connecting bottom part 919 to move and stretches the outer pulling spring rod 918. At this time, the connecting bottom part 919 drives the mounting base 914 and the positioning roller member 913 to move to adjust according to the size of the target plate connecting rod 10. At the same time, the guiding belt 911 is stretched and unfolded accordingly. At this time, the target plate connecting rod 10 enters between two of the positioning roller members 913 under the guidance of the guiding belt 911 and continues to move to pass through the other two positioning roller members 913. At this time, the positioning of the target plate connecting rod 10 is completed through the four positioning roller members 913. At the same time, when positioning the target plate connecting rod 10, as the target plate connecting rod 10 moves, it will push the connecting rod push block 925 to move and compress the pressure spring rod 906. At this time, the connecting rod push block 925 can drive the fixed toothed plate 905 to move. Since the two fixed toothed plates 905 are meshed with two of the linkage gear teeth 927, it can drive them to rotate. When rotating, it drives the other two linkage gear teeth to rotate through the transmission belt 928. Further, it drives the two movable toothed plates 926 to move on the guide rail plate seat, so that the two movable toothed plates 926 drive the two pushing plate frames 904 to approach each other. Further, the telescopic spring 929 drives the positioning push plate 902 to move to push the shooting target plate 11 until the telescopic spring 929 is compressed to the limit (the setting of the telescopic spring 929 enables the device to perform positioning operations on shooting target plates 11 of different sizes), so that the two positioning push plates 902 simultaneously complete the clamping of the shooting target plate 11, and further complete the synchronous positioning of the shooting target plate 11 and the target plate connecting rod 10;

[0041] In a specific application scenario, the welding positioning module 9 is suitable for the welding positioning link of the training target machine, that is, the welding positioning module 9 can synchronously adjust and position the shooting target plate 11 and the target plate connecting rod 10 when in use, so that the welding position of the shooting target plate 11 corresponds to the target plate connecting rod 10, thereby ensuring the accuracy of the welding position of the shooting target plate 11 and the target plate connecting rod 10 during welding, avoiding deviations during the welding process, thereby increasing the welding quality of the device and improving the use effect of the device. When increasing the welding quality, it can avoid data deviations when the training target machine is used, thereby ensuring the training effect and use effect of the training target machine.

[0042] Reference Figure 2 、 Figure 7 and Figure 8 In a preferred embodiment, the welding module 8 further comprises a guide rail seat 801, which is fixedly connected to the welding base 1, and a linear screw 808 is provided on the guide rail seat 801. A stepper motor 802 is fixedly connected to an outer wall of one side of the guide rail seat 801, and the output shaft of the stepper motor 802 is connected to one end of the linear screw 808 through a coupling, and the linear screw 808 and the guide rail seat 801 are provided with the same movable base 812, and the outer walls on both sides of the movable base 812 are fixedly connected to the inward spring rod 804, and one end of the two inward spring rods 804 are fixedly connected. Welding support plate 805; the two welding gun bodies 806 are respectively fixedly connected to the two welding support plates 805, and the outer walls on the opposite sides of the two welding support plates 805 are fixedly connected with an opening and closing wheel frame 810, and the two opening and closing wheel frames 810 are each provided with an unfolding contact wheel 811, and the top of the guide rail seat 801 is fixedly connected with two bracket members 807, and the two bracket members 807 are fixedly connected with a mounting rod member 809, and the two mounting rod members 809 are fixedly connected to the same opening and closing plate member 803 at one end on the same side, and the two opening and closing plates 803 are both located between the two unfolding contact wheels 811.

[0043] Specifically, during welding, the stepper motor 802 and the welding gun body 806 are started, and the stepper motor 802 drives the linear screw 808 to rotate, and then the movable base 812 is made to move linearly with the cooperation of the guide rail seat 801, thereby driving the inward spring rod 804, the welding support plate 805 and the welding gun body 806 to move. During the movement, the inward spring rod 804 will pull the welding support plate 805 inward until it moves to a certain position. The welding support plate 805 drives the welding gun body 806 to approach and make the welding gun body 806 contact with the welding part to perform welding. After welding, as the movable base 812 continues to operate, the unfolding contact wheel 811 will contact the opening and closing plate 803, and then the two welding support plates 805 will be pushed to both sides, so that the welding gun body 806 is separated from the welding part, and the welding is completed.

[0044] In a specific application scenario, the welding module 8 is applicable to the welding link of the training target drone, that is, when the welding module 8 is in use, it can perform rotational welding on the welding part of the shooting target plate 11 and the target plate connecting rod 10, thereby increasing the automation effect of the device during welding, improving the welding efficiency. Moreover, during welding, the device can weld shooting target plates 11 and target plate connecting rods 10 of different sizes, increasing the applicability of the device. At the same time, after welding, it can automatically separate from the welding part to avoid over-welding, further improving the welding quality of the device.

The output end of the air pump 502 is fixedly connected to two delivery pipes 503. The two delivery pipes 503 are respectively communicated with the interiors of the two pressing airbags 508. Moreover, two fixing openings are formed on the positioning frame 901. An upper supporting airbag one 505 and an upper supporting airbag two 507 are respectively fixedly connected to the inner walls of the two fixing openings. Two communicating pipes 506 are arranged at the bottoms of the upper supporting airbag one 505 and the upper supporting airbag two 507. The tops of the two pressing airbags 508 are fixedly connected to connecting pipes 504. The output ends of the two connecting pipes 504 are both communicated with the interior of the upper supporting airbag one 505. The tops of the upper supporting airbag one 505 and the upper supporting airbag two 507 are both in contact with the bottom of the target plate connecting rod 10.

[0046] Specifically, after positioning, the air pump 502 is started. The air pump 502 delivers gas into the two pressing airbags 508 through the delivery pipes 503, so that the pressing airbags 508 expand to apply a downward pressure on the shooting target plate 11. At the same time, the gas inside the pressing airbags 508 will be delivered to the upper supporting airbag one 505 through the connecting pipes 504 and further enter the interior of the upper supporting airbag two 507 through the communicating pipes 506, causing the pressing airbags 508 and the upper supporting airbag one 505 and the upper supporting airbag two 507 to expand simultaneously, and applying an upward pressure on the target plate connecting rod 10 through the upper supporting airbag one 505 and the upper supporting airbag two 507, so that the top of the target plate connecting rod 10 is in contact with the bottom of the shooting target plate 11 (the pressure applied simultaneously can increase the stability of the positioning position);

[0047] In a specific application scenario, the welding and fitting module 5 is applicable to the fitting and fixing link of the shooting target plate 11 and the target plate connecting rod 10. That is, when the welding and fitting module 5 is in use, it can apply opposite pressures to the shooting target plate 11 and the target plate connecting rod 10 to ensure their close fitting during welding, avoid void welding, thereby ensuring the welding effect and further enhancing the welding effect of the device. Moreover, during fitting, the applied pressure can assist in fixing the shooting target plate 11 and the target plate connecting rod 10, thus increasing the welding positioning stability of the device and enhancing the usage effect of the device.

[0048] A method for positioning and welding metal parts of a training target machine, using a positioning and welding device for metal parts of a training target machine as described above, includes the following steps:

[0049] Step 1: Before positioning, the shooting target plate 11 and the target plate connecting rod 10 are respectively arranged on the target plate table 2 and the connecting rod support table 6, and the shooting target plate 11 is made to contact the baffle member 3 for placement before positioning.

[0050] Step 2: During positioning, the electric push rod 13 drives the pushing plate 12 to push the target plate connecting rod 10, so that one end of the target plate connecting rod 10 enters the inside of the positioning frame 901. During this process, the driving motor 923 operates and drives the cable reel 922 to rotate to wind up the connecting cable 921. As a result, the connecting cable 921 pulls the connecting bottom member 919 to move, and the outer pulling spring rod 918 is stretched. At this time, the connecting bottom member 919 drives the mounting base 914 and the positioning roller member 913 to move for adjustment according to the size of the target plate connecting rod 10. At the same time, the guiding belt 911 is stretched and unfolded accordingly. At this time, the target plate connecting rod 10 enters between two of the positioning roller members 913 under the guidance of the guiding belt 911 and continues to move to pass through the other two positioning roller members 913. At this time, the positioning of the target plate connecting rod 10 is completed by the four positioning roller members 913. At the same time, when positioning the target plate connecting rod 10, as the target plate connecting rod 10 moves, it will push the connecting rod push block 925 to move, and the pressure spring rod 906 is compressed. At this time, the connecting rod push block 925 can drive the fixed toothed plate 905 to move. Since the two fixed toothed plates 905 are engaged with two of the linkage gear teeth 927, they can drive them to rotate, and when rotating, they drive the other two linkage gear teeth 927 to rotate through the transmission belt 928, thereby driving the two movable toothed plates 926 to move on the guide rail plate seat, so that the two movable toothed plates 926 drive the two pushing plate frames 904 to approach each other, and then the telescopic spring 929 drives the positioning push plate 902 to move to push the shooting target plate 11 until the telescopic spring 929 is compressed to the limit, so that the two positioning push plates 902 simultaneously complete the clamping of the shooting target plate 11, and thus the synchronous positioning of the shooting target plate 11 and the target plate connecting rod 10 is completed.

[0051] Step 3: After positioning, start the air pump 502, and the air pump 502 delivers gas to the two downward pressure air bags 508 through the delivery pipe 503, so that the downward pressure air bags 508 expand, thereby applying downward pressure to the shooting target plate 11. At the same time, the gas inside the downward pressure air bag 508 will be delivered to the upper support air bag 1 505 through the connecting pipe 504, and further enter the upper support air bag 2 507 through the connecting pipe 506, so that the downward pressure air bag 508 and the upper support air bags 1 505 and 507 expand simultaneously, and the upper support air bags 1 505 and 507 apply upward pressure to the target plate connecting rod 10, so that the top of the target plate connecting rod 10 fits with the bottom of the shooting target plate 11.

[0052] Step 4: During welding, start the stepper motor 802 and the welding gun body 806, and the stepper motor 802 drives the linear screw 808 to rotate, and then the movable base 812 performs linear motion with the cooperation of the guide rail seat 801, thereby driving the inward spring rod 804, the welding support plate 805 and the welding gun body 806 to move. During the movement, the inward spring rod 804 will pull the welding support plate 805 inward until it moves to a certain position. The welding support plate 805 drives the welding gun body 806 to approach and makes the welding gun body 806 contact with the welding part for welding. After welding, as the movable base 812 continues to operate, the unfolded contact wheel 811 will contact the opening and closing plate 803, and then push the two welding support plates 805 to both sides to separate the welding gun body 806 from the welding part, completing the welding.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
