[0014] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0015] Please refer to Figures 1 - 10, an embodiment of the present invention is: a magnetic pump housing welding production and processing device, including a box body 1, a frame 2 is fixedly connected to the top of the box body 1, a tensioning mechanism 3 is installed inside the box body 1, a feeding mechanism 4 is arranged on the inner wall of the frame 2 of the box body 1, a lift power cabinet 5 is arranged inside the box body 1, a discharging mechanism 6 is arranged on the left side of the box body 1, a fixed chuck 7 is installed on the top of the box body 1 and the tensioning mechanism 3 is located at the axis of the fixed chuck 7, a box door 8 is hinged to the front of the box body 1, a welding robot arm 9 is installed on the top of the box body 1, and the tensioning mechanism 3 includes: a base 301, a hydraulic strut 302, a support plate 303, a sleeve 304, a connecting rod one 305, a connecting rod two 306, a strut 307, a top rod 308, a heat shield 309, an arc-shaped top block 310, a mounting post 311, and a connecting plate 312. The base 301 is fixedly connected to the top inner wall of the box body 1, the hydraulic strut 302 is fixedly connected to the top of the base 301, the mounting post 311 is fixedly connected to the top of the base 301, the sleeve 304 is movably connected to the circumferential surface of the mounting post 311, the support plate 303 is fixedly connected to the bottom of the sleeve 304, the connecting rod one 305 is hinged to the circumferential surface of the sleeve 304, the connecting rod two 306 is hinged to the circumferential surface of the sleeve 304, the strut 307 is hinged to the middle of the connecting rod two 306, the connecting plate 312 is fixedly connected to one end of the mounting post 311 away from the base 301, the top rod 308 is fixedly connected to the top of the sleeve 304, and the top rod 308 passes through the mounting post 311 and is fixedly connected to the heat shield 309. A heating device is installed on the top of the connecting plate 312, and the heating device is blocked by the heat shield 309. The hydraulic strut 302 is located between the support plate 303 and the base 301, and the output end of the hydraulic strut 302 is fixedly connected to the bottom of the support plate 303. One end of the connecting rod one 305 away from the sleeve 304 is hinged to the bottom of the arc-shaped top block 310, one end of the connecting rod two 306 away from the sleeve 304 is hinged to the inner wall of the arc-shaped top block 310, and one end of the strut 307 away from the connecting rod two 306 is hinged to the mounting post 311. During the welding process, the arc-shaped top block 310 tightens the barrel wall to provide radial restraint to resist shrinkage deformation, effectively reducing thermal deformation during the welding process and improving the yield rate of the tool. At the same time, the movement of the top rod 308 pushes the heat shield 309 to open, exposing the internal heating component to preheat the workpiece, reducing the temperature difference between the welding area and the base material, reducing thermal stress, slowing down the cooling rate, preventing cold cracks, further reducing thermal deformation during the welding process. After the welding is completed, the reset of the hydraulic strut 302 can also make the heat shield 309 close again to prevent the heating component from hurting the operator.

[0016] Working principle: The feeding mechanism 4 of the device moves the pump body to be welded to the chuck 7. The chuck 7 clamps the workpiece. At this time, the hydraulic strut 302 extends to push the support plate 303 to move. The movement of the support plate 303 drives the sleeve 304 to move upward. The upward movement of the sleeve 304 drives the first connecting rod 305 and the second connecting rod 306 to move upward. Since the second connecting rod 306 is restricted by the strut 307, the first connecting rod 305 can only rotate around the hinge point between it and the sleeve 304. The rotation of the first connecting rod 305 drives the arc-shaped top block 310 to expand outward until it contacts and tightens the pump body to be welded. During the welding process, the arc-shaped top block 310 tightens the cylinder wall, provides radial restraint to resist shrinkage deformation, effectively reduces the thermal deformation during the welding process, and improves the yield rate of the tool. During the upward movement of the sleeve 304, the ejector rod 308 is driven to move. The movement of the ejector rod 308 pushes the heat shield 309 to open, exposing the internal heating component, preheating the workpiece, reducing the temperature difference between the welding area and the base material, reducing thermal stress, slowing down the cooling rate, preventing cold cracks, further reducing the thermal deformation during the welding process. After the welding is completed, the reset of the hydraulic strut 302 can also close the heat shield 309 again to prevent the heating component from hurting the operator.

[0017] Please refer to Figures 1 - 10 , on the basis of the above embodiment, in another embodiment of the present invention, the feeding mechanism 4 includes: a convex guide rail 401, a mounting plate 402, a workpiece chuck 403, a slider 404. The convex guide rail 401 is fixedly connected to the inner wall of the frame 2. The mounting plate 402 is slidably connected to the inner wall chute of the convex guide rail 401. The slider 404 is slidably connected to the surface of the mounting plate 402. The workpiece chuck 403 is fixedly connected to the bottom of the slider 404. The feeding mechanism 4 further includes: an arc-shaped block 405, a return spring 406, a fork tooth 407, a lifter 408. The return spring 406 is fixedly installed between the two sliders 404. The arc-shaped block 405 is fixedly connected to the end of the slider 404 away from the return spring 406. The lifter 408 is installed on the right side of the box body 1. The fork tooth 407 is fixedly connected to the right side of the lifter 408. The arc-shaped block 405 is slidably connected to the mounting plate 402. A conveyor belt for the pump body workpiece to be welded is installed on the right side of the lifter 408. The mounting plate 402 and its attached components, the workpiece chuck 403, the slider 404, the arc-shaped block 405, and the return spring 406 are provided in two sets, and the two sets of mechanisms move synchronously and are driven by the same power source. The arc-shaped block 405 on the left side of the frame 2 is slidably connected to the bottom of the mounting plate 402, and the arc-shaped block 405 on the right side of the frame 2 is slidably connected to the top of the mounting plate 402. The protrusions on the upper layer and the lower layer of the convex guide rail 401 are staggered and do not overlap. The workpiece chuck 403 opens to let the workpiece fall into the fixed chuck 7. At the same time, the feeding and discharging operations are completed, reducing the standby rest time, simplifying the work process, significantly improving the production efficiency, and at the same time, this simple structure also reduces the maintenance cost.

[0018] The discharging mechanism 6 includes: a sliding rod 601, a rack 602, a gear 603, and a wire reel 604. The sliding rod 601 is slidably connected to the inner wall of the convex guide rail 401. The rack 602 is fixedly connected to the bottom of the sliding rod 601. The gear 603 is fixedly connected to the left side of the convex guide rail 401. The wire reel 604 is installed at the bottom near one end of the gear 603. The discharging mechanism 6 further includes: a buffer plate 605, an inclined plate 606, and a convex rod 607. The buffer plate 605 is hinged to the left side of the box body 1. The inclined plate 606 is fixedly connected to the left side of the box body 1. The convex rod 607 is fixedly connected to the inclined surface of the inclined plate 606 and is arranged in a symmetric and staggered manner. The rack 602 meshes with the gear 603. The gear 603 is connected to the wire reel 604 through a chain drive. A steel wire rope is wound around the circumferential surface of the wire reel 604. One end of the steel wire rope away from the wire reel 604 is fixedly connected to the top of the buffer plate 605. Through the buffering and guiding of the buffer plate 605, the dumping direction of the workpiece is ensured, ensuring the smooth progress of the subsequent process, improving production efficiency and stability. When the workpiece rolls down, it continuously contacts and collides with the convex rod 607 to vibrate itself, which can shake off the welding slag generated by welding and can also detect whether the weld is firm.

[0019] Working principle: After the previous welding is completed, the elevator 408 starts to drive the fork teeth 407 to move upward to fork and transport the workpiece on the conveyor belt to the limit position. The mounting plate 402 on the left side of the frame 2 is driven by the motor inside the convex guide rail 401 and moves to the left side of the device. The movement of the mounting plate 402 drives the movement of the slider 404. The movement of the slider 404 drives the movement of the arc block 405. During the movement of the arc block 405, it contacts the convex block on the lower layer of the convex guide rail 401, causing the two arc blocks 405 to be squeezed and move inward and compress the return spring 406. The movement of the arc block 405 drives the movement of the workpiece chuck 403. At this time, the mounting plate 402 moves to the upper part of the welded workpiece. The arc block 405 is also squeezed to the minimum stroke, and the workpiece chuck 403 clamps the workpiece. The mounting plate 402 continues to move to drive the workpiece clamped by the workpiece chuck 403 to the area of the discharging mechanism 6. At the same time, the mounting plate 402 on the right side of the frame 2 repeats the above movement trajectory, except that the mounting plate 402 on the right side of the device moves to the left side of the device. During the movement of the arc block 405, the convex block it contacts is on the upper layer of the convex guide rail 401, so that the workpiece chuck 403 clamps the un-welded workpiece on the fork teeth 407. Then the elevator 408 descends, and the slider 404 continues to move to drive the workpiece to be welded clamped by the workpiece chuck 403 to the upper part of the fixed chuck 7. At this time, the mounting plate 402 leaves the area of the convex block on the upper layer of the convex guide rail 401. The arc block 405 loses restraint and is forced by the return spring 406 to reset, causing the slider 404 to move back to the initial position. The workpiece chuck 403 opens and the workpiece falls into the fixed chuck 7. At the same time, the operations of loading and unloading are completed, reducing the standby and rest time, simplifying the work process, significantly improving production efficiency, and at the same time, this simple structure also reduces the maintenance cost.

[0020] When the welded workpiece is moved to the discharging mechanism 6, the mounting plate 402 will contact and push the sliding rod 601 to move. The movement of the sliding rod 601 drives the meshing gear 603 to rotate. The rotation of the gear 603 drives the wire reel 604 to rotate through a chain. As the sliding rod 601 moves, the wire reel 604 slowly winds up the steel wire rope. During the winding process of the steel wire rope, the buffer plate 605 is driven to rotate until it is flush with the top plane of the box body 1. At this time, the mounting plate 402 leaves the lower convex block area of the convex guide rail 401. The arc-shaped block 405 loses its restraint and the force of the return spring 406 causes the slider 404 to move back to the initial position. The workpiece chuck 403 opens to let the workpiece fall onto the surface of the buffer plate 605. Subsequently, the mounting plate 402 moves back. The sliding rod 601 loses its restraint due to the weight of the workpiece, and the buffer plate 605 resets to fit the inclined surface of the inclined plate 606, causing the workpiece to tilt. The buffer and guiding functions of the buffer plate 605 ensure the tilting direction of the workpiece, guarantee the smooth progress of the subsequent process, and improve production efficiency and stability. When the workpiece rolls down, it continuously contacts and collides with the convex rod 607, causing itself to vibrate, which can shake off the welding slag generated by welding and also detect whether the weld is firm.
