DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides Figure 1-Figure 8A welding positioning tool shown in the figure includes a workbench 1, which includes a recovery mechanism and two clamping mechanisms. The clamping mechanism is arranged on the recovery mechanism. The two clamping mechanisms each include a slider 8, a clamping block 9, a turntable 10, a damping shaft 11, a threaded rod 12 and a clamping plate 13. A first rotating hole is opened on the left side of the turntable 10 near the center. The damping shaft 11 is arranged in the first rotating hole. One end of the damping shaft 11 is fixedly connected to the turntable 10. A second rotating hole is opened on the left side of the slider 8. The damping shaft 11 is arranged in the second rotating hole. The damping shaft 11 can rotate in the slider 8. The first rotating hole and the second rotating hole are horizontally arranged in the same horizontal plane. The other end of the damping shaft 11 is fixedly connected to the clamping block 9. A first threaded hole is opened on the top of the clamping block 9. The threaded end of the threaded rod 12 is threadedly connected to the first threaded hole. A rotating groove is opened on the top of the clamping plate 13 near the center. The bottom end of the threaded rod 12 is arranged in the rotating groove. The bottom end of the threaded rod 12 can rotate in the clamping plate 13. The threaded rod 12 is rotatably connected to the clamping plate 13. When the threaded rod 12 is rotated, the clamping plate 13 performs a linear motion up and down through the threaded transmission of the threaded rod 12 to clamp the metal parts. A handle is provided on the end of the left and right turntables 10 away from the slider 8. The two handles are rotated respectively with the damping shaft 11 as the center to drive the turntable 10 to rotate. The turntable 10 rotates synchronously with the damping shaft 11 and the clamping block 9. The turntable 10 drives the damping shaft 11 to rotate in the slider 8, and the damping shaft 11 drives the clamping block 9 to rotate on one side of the slider 8, thereby realizing the separate rotation of the two sections of metal parts, and rotation welding can be performed without disassembly. In summary, the problem of repeated disassembly and assembly required for adjusting the angle of the clamped metal parts and complicated operation is solved.

[0026] The two clamping blocks 9 are provided with clamping grooves on opposite sides, and the two clamping grooves are provided with sliding grooves on opposite sides. The two clamping plates 13 can slide in the two clamping grooves and the two sliding grooves respectively. When the threaded rod 12 and the first threaded hole of the slider 8 are threadedly driven, the clamping grooves and the sliding grooves of the clamping block 9 limit the clamping plate 13. In summary, the problem of the clamping plate 13 rotating with the threaded rod 12 is solved, making the sliding more stable.

[0027] The recovery mechanism includes a cold water pool 14, a recovery frame 15, a first water outlet pipe 17, a stop valve 18, a second water outlet pipe 20 and two limit bars 16. The second water outlet pipe 20 is detachably connected to the output end of the stop valve 18, and the input end of the stop valve 18 is detachably connected to the bottom end of the first water outlet pipe 17. A water outlet is opened at the bottom of the cold water pool 14, and the top end of the first water outlet pipe 17 is arranged in the water outlet. The top end of the first water outlet pipe 17 is fixedly connected to the bottom of the cold water pool 14. The two limit bars 16 are respectively fixedly connected to the front and rear sides of the inner wall of the cold water pool 14, and the recovery frame 15 is arranged on the top of the two limit bars 16. The cold water pool 14 is arranged below the welding position and is filled with cold water. The metal liquid generated by welding falls into the cold water to be pre-cooled to form a solid and then falls into the recovery frame 15. The recovery frame 15 is arranged on the limit bar 16 in the cold water pool 14 to prevent the limit bar 16 from playing a supporting role. A handle is arranged above the recovery frame 15, and the recovery frame 15 can be taken away by picking up the handle. After a certain period of use, the cold water is replaced, and the external water bucket is placed under the second water outlet pipe 20. The stop valve 18 is opened, and the cold water in the cold water pool 14 enters the water bucket through the first water outlet pipe 17, the stop valve 18 and the second water outlet pipe 20 in turn. In summary, the problem of metal liquid generated during welding dripping onto the surface of the workbench 1 causing waste of resources is solved.

[0028] The recycling frame 15 is arranged inside the cold water pool 14, and a metal mesh is arranged at the bottom of the recycling frame 15. The metal mesh is made of stainless steel. A square opening is opened in the middle of the top of the workbench 1, and the cold water pool 14 is arranged in the square opening. The cold water pool 14 is fixedly connected to the workbench 1. The metal mesh inside the recycling frame 15 can filter liquid and metal solids. When picking up the recycling frame 15, cold water passes through the metal mesh, and the metal solids stay above the metal mesh. In summary, the problem of difficult distinction between cold water and metal solids is solved.

[0029] Two vertical plates 2 are fixedly connected to the top of the workbench 1, a fixed plate 3 is fixedly connected between the two vertical plates 2, a double-headed motor 4 is detachably connected to the middle of the top of the fixed plate 3, and the output ends of the double-headed motor 4 are respectively fixedly connected to the first bevel gears 5, a circular hole is opened near the center of the top of the two vertical plates 2, a lead screw 7 is respectively arranged in the two circular holes, and the tops of the two lead screws 7 are respectively fixedly connected to the second bevel gears 6, and the two second bevel gears 6 are respectively meshed with the two first bevel gears 5, and two sliding holes are respectively opened at the front and rear ends of the two vertical plates 2, and eye shields 19 are arranged in the four sliding holes, and the two eye shields 19 can slide in the four sliding holes respectively. The double-headed motor 4 drives the first bevel gear 5 to rotate, and the first bevel gear 5 is transmitted to the second bevel gear 6. The second bevel gear 6 drives the lead screw 7 to rotate, and the slider 8 performs a linear motion up and down through the threaded transmission of the lead screw 7. The vertical plates 2 are all provided with a movable space for the slider 8, which is convenient for the up and down movement of the slider 8 while clamping and limiting the slider 8. The slider 8 drives the clamped metal parts to move up and down. According to the welding position, the eye shield 19 is slid and closed on the opposite side of the welding position. In summary, the problems of strong light pollution and metal liquid splashing on the non-welding surface are solved.

[0030] The front and rear ends of the top of the workbench 1 are respectively provided with slide grooves, and two eye guards 19 are respectively arranged on the two slide grooves. The two eye guards 19 can slide in the two slide grooves respectively. The tops of the two sliders 8 are provided with second threaded holes, and the two lead screws 7 are respectively arranged in the two second threaded holes. The threaded ends of the two lead screws 7 are respectively threadedly connected with the two sliders 8. The eye guard 19 can slide in the slide hole and the slide groove at the same time. In summary, the problem of insufficient sliding track and unstable sliding is solved.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
