[0027] 2. In the present invention, a welding device for metal target material processing is described, wherein the first monitoring wheel and the second monitoring wheel are in contact with the outside of the target material by means of a supporting spring, and the target material drives the first monitoring wheel and the second monitoring wheel to rotate when rotating, and the first monitoring wheel drives the bidirectional screw to rotate synchronously, and the bidirectional screw drives the rotating box to rotate through the connecting shaft, and when the rotating box rotates, the two horizontal plates move away from each other under the action of centrifugal force, and the vertical plate is driven to move laterally through the connecting rope, and the vertical plate drives the side plate to move laterally through the round rod, and the side plate drives the second conductive sheet to move laterally, and the lateral movement distance of the second conductive sheet is directly related to the rotation speed of the target material, and when the second conductive sheet contacts the fourth conductive sheet, the circuit of the welding gun is turned on, and then the welding gun is driven to approach the target material by starting the electric push rod to achieve welding work;

[0028] 3. In the present invention, in the welding device for processing metal target materials, when the two targets are closely abutted and no offset occurs during the welding process, the first monitoring wheel and the second monitoring wheel are pressed against the outside of the target materials, so that the first monitoring wheel and the second monitoring wheel rotate synchronously. The second monitoring wheel drives the threaded sleeve to rotate during the rotation. When the threaded sleeve rotates, it will be able to lift the pin until the pin is aligned with another arc-shaped groove. The pin is reinserted into the arc-shaped groove under the action of the vertical spring.

After welding is completed, the second drive motor is stopped to stop the rotation of the target material, so that the horizontal plate is reset under the elastic force of the compression spring, the vertical plate is reset under the action of the connecting spring, and the second conductive sheet is driven to reset through the round rod and the side plate, causing it to be out of contact with the fourth conductive sheet, thereby stopping welding;

[0031] 6.

[0060] In this embodiment, the same connecting shaft 5 is rotatably installed in the two supporting plates 101, and the rotating cylinder 604 is rotatably installed inside the two moving plates 7.

[0063] In this embodiment, a square groove is opened on the top of the base 1, and the mounting plate 8 is slidably connected in the square groove, and the bottom of the mounting plate 8 is fixedly connected with a support spring 802 and a vertical rod 801, the bottom end of the support spring 802 is fixedly connected to the bottom inside of the square groove, and a vertical hole is opened on the bottom inside of the square groove, and the vertical rod 801 is slidably connected in the corresponding vertical hole, thereby resetting and guiding the mounting plate 8.

[0064] In this embodiment, the clamp includes a shell 2, a driving disk 205 and a plurality of clamping jaws 201, one side of the shell 2 is fixedly connected to a rotating motor 206, the output shaft of the rotating motor 206 is fixedly connected to one side of the driving disk 205, and one side of the driving disk 205 is provided with a plurality of arc holes 2051, the plurality of clamping jaws 201 are arranged in a ring at equal intervals, and one side of the clamping jaw 201 is fixedly connected to a square rod 203, the other end of the square rod 203 is fixedly connected to a connecting column 204, the connecting column 204 is movably inserted in the arc hole 2051, the sides of the plurality of clamping jaws 201 away from each other are fixedly connected to a sliding rod 202, the shell 2 is slidably sleeved on the outside of the sliding rod 202, and the shell 2 is fixedly connected to the corresponding connecting frame 601.

[0065] In this embodiment, two side rods are fixedly connected to both sides of the base 1, and the two movable plates 7 are slidably sleeved on the outer sides of the corresponding side rods, so as to guide the movable plates 7 to move horizontally.

[0066] In this embodiment, when in use, by placing two targets in two clamps and then starting to move them closer to each other, the connecting column 204 drives the multiple clamping plates to move closer to each other through the square rod 203, thereby clamping the two targets;

[0067] The first driving motor 403 is started to drive the first driving gear 402 to rotate. The first driving gear 402 drives the bidirectional screw 4 to rotate by meshing with the first driven gear 401. The bidirectional screw 4 drives the two moving plates 7 to approach each other through thread transmission with the two moving plates 7 and under the guidance of the side rod. The two moving plates 7 drive the two targets to approach each other and press the two targets tightly.

[0068] The second driving motor 503 is started to drive the second driving gear 5402 to rotate. The second gear drives the connecting shaft 5 to rotate by meshing with the second driven gear 501. The connecting shaft 5 drives the two rotating drums 604 to rotate synchronously through the limit bar. The two rotating drums 604 drive the two driving sprockets 603 to rotate. The chains corresponding to the two driving sprockets 603 drive the two driven sprockets 602 to rotate, and drive the housing 2 to rotate through the mounting shaft 6 and the connecting frame 601, thereby driving the two targets to rotate.

[0069] The support spring 802 is provided to make the first monitoring wheel 11 and the second monitoring wheel 12 abut against the outer side of the target material. When the target material rotates, it drives the first monitoring wheel 11 and the second monitoring wheel 12 to rotate. The first monitoring wheel 11 drives the bidirectional screw 9 to rotate synchronously. The bidirectional screw 9 drives the rotating box 15 to rotate through the connecting shaft 901. When the rotating box 15 rotates, the two horizontal plates 25 move away from each other under the action of centrifugal force, and drive the vertical plate 19 to move horizontally through the connecting rope 28. The vertical plate 19 drives the side plate 17 to move horizontally through the round rod 16. The side plate 17 drives the second conductive sheet 22 to move horizontally, and the horizontal movement distance of the second conductive sheet 22 is directly related to the rotation speed of the target material. When the second conductive sheet 22 contacts the fourth conductive sheet 24, the circuit of the welding gun 3 is turned on, and then the welding gun 3 is driven to approach the target material by starting the electric push rod 301 to achieve welding.

[0070] During the welding process, when the two targets are tightly abutted and no offset occurs, the first monitoring wheel 11 and the second monitoring wheel 12 are pressed against the outside of the target, so that the first monitoring wheel 11 and the second monitoring wheel 12 rotate synchronously. The second monitoring wheel 12 drives the threaded sleeve 13 to rotate during rotation. When the threaded sleeve 13 rotates, it will be able to lift the latch 1401 until the latch 1401 is aligned with another arc-shaped groove. The latch 1401 is reinserted into the arc-shaped groove under the action of the vertical spring 1402. Since the first monitoring wheel 11 and the second monitoring wheel 12 rotate synchronously, there is no relative rotation between the threaded sleeve 13 and the bidirectional screw 9, and therefore the linkage plate 14 will not move relatively, so that the circuit of the welding gun 3 remains on for welding.

[0071] Once there is a gap or offset between the two targets, so that one of the second monitoring wheels 12 is out of contact with the target, the threaded sleeve 13 and the second monitoring wheel 12 stop rotating due to the resistance of the latch 1401, and the bidirectional screw 9 drives the linkage plate 14 and the first conductive sheet 21 to move laterally through the threaded sleeve 13 and under the guidance of the guide rod, the first conductive sheet 21 moves laterally and is out of contact with the corresponding third conductive sheet 23, thereby cutting off the power to the welding gun 3 and stopping the welding work;

[0072] When the target rotates too fast during welding, the lateral movement distance of the second conductive sheet 22 will increase, causing it to lose contact with the corresponding fourth conductive sheet 24, thereby powering off the welding gun 3 and stopping the welding operation;

[0073] After welding is completed, the second drive motor 503 is stopped to stop the target material from rotating, so that the horizontal plate 25 is reset under the elastic force of the compression spring 26, and the vertical plate 19 is reset under the action of the connecting spring 29, and the second conductive sheet 22 is reset through the round rod 16 and the side plate 17, so that it is out of contact with the fourth conductive sheet 24, thereby stopping the welding work.

[0074] The above is a detailed introduction to a welding device for metal target material processing provided by the present invention. Specific embodiments are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
