The rotating rod 41 is symmetrically rotatably connected between the upper and lower inner walls of the mounting box 3. The upper end of the rotating rod 41 extends to the upper side of the mounting box 3. The upper end of the rotating rod 41 is fixedly connected to the fixing platform 42. The upper surfaces of the two fixing platforms 42 are fixedly connected to the holding platforms 43. The rear sides of the upper surfaces of the fixing platforms 42 are symmetrically fixedly connected to the rear rectangular tubes 44.

The multi-angle fixing mechanism 4 includes a front sliding cylinder 46, with front clamps 47 slidably connected inside each front sliding cylinder 46. It also includes a longitudinal limiting beam 48 and a limiting groove 49. The longitudinal limiting beam 48 is fixedly connected to the middle of the front and rear inner walls of the two front sliding cylinders 46. Limiting grooves 49 are respectively opened on the front sides of the two front clamps 47. The outer surfaces of the longitudinal limiting beams 48 are slidably connected to the inner walls of the limiting grooves 49 on the same side. Limiting telescopic rods 5 are symmetrically fixedly connected to the rear sides of the two rear clamps 45 and the front sides of the corresponding longitudinally positioned front clamps 47. Vertical U-shaped frames 13 are respectively provided on the rear side of the upper surface of the fixing platform 42. Sealing shafts connect the upper and lower inner walls of the vertical U-shaped frames 13. A vertical screw 7 is rotatably connected to the rear clamp 45 located on the same side. The external thread of the vertical screw 7 is threadedly connected to the middle of the rear clamp 45 located on the same side. The lower front side of the rear clamp 45 is provided with a longitudinal U-shaped frame 12. The front and rear inner walls of the longitudinal U-shaped frame 12 are also rotatably connected with a longitudinal screw 6 through a sealed bearing.

The upper ends of the two vertical screws 7 and the front ends of the two longitudinal screws 6 are respectively fixedly connected to a tightening block through a fixed shaft. The front and rear side walls of the longitudinal U-shaped frame 12 are respectively fixedly connected with a vertical protective bellows. The rear end of the vertical protective bellows on the front side and the front end of the vertical protective bellows on the rear side are respectively connected to the outer surface of the front clamp 47 located on the same side. The vertical protective bellows seals the external thread surface of the longitudinal screw 6. When the front clamp 47 moves back and forth, the vertical protective bellows adapts to expand and contract, protecting the external thread surface of the longitudinal screw 6 in real time. The upper and lower side walls of the vertical U-shaped frame 13 are respectively fixedly connected with longitudinal protective bellows. The lower end of the upper longitudinal protective bellows and the upper end of the lower longitudinal protective bellows are respectively fixedly connected to the outer surface of the rear clamp 45 located on the same side. The longitudinal protective bellows protect the external thread surface of the vertical screw 7. When the rear clamp 45 moves up and down, the longitudinal protective bellows adapt to expand and contract, protecting the external thread surface of the vertical screw 7 in real time. Worm gears 8 are fixedly connected to the lower side of the outer arc surface of the rotating rod 41.Worms 9 are rotatably connected to the middle of the left and right walls of the mounting box 3, respectively. The worms 9 mesh with worms 9 in the longitudinal position. The two worms 9 have opposite directions of rotation and are fixedly connected. A torsion valve 10 is fixedly connected to the right end of the right worm 9. The worm wheel 8 and the worm 9 are both located inside the mounting box 3. Support platforms 14 are respectively provided on the left and right sides of the upper surface of the fixing frame 1. The upper surface of the support platform 14 is at the same horizontal height as the upper surface of the holding platform 43. The torsion valve 10 can be twisted in both directions, causing the two worms 9 to rotate simultaneously in both directions. The rotation of the two worms 9 drives the rotating rod 41 to rotate through the worm wheel 8. Since the two worms 9 have opposite directions of rotation, the two rotating rods 41 also rotate in opposite directions. The left fixing platform 42 rotates around the central axis of the left rotating rod 41, and the right fixing platform 42 rotates around the central axis of the right rotating rod 41. Then, the mining accessories to be welded can be placed on the support platform, and the side to be welded can be placed on... On the holding platform 43, and with the front side wall of the rear clamp 45 pressed against the mining accessory to be welded, as the fixed platform 42 rotates, the welding surfaces of the two accessories align, defining the welding line. At this point, the tightening block on the front side of the left longitudinal screw 6 can be turned, causing the left longitudinal screw 6 to rotate, thereby moving the left front clamp 47 backward until the rear side of the left front clamp 47 contacts the front side of the mining accessory. Then, the tightening block on the upper side of the left vertical screw 7 can be turned, causing... The left rear clamp 45 and the left front clamp 47 move downwards synchronously until their upper walls clamp the upper surface of the mining accessory, thus securing the left mining accessory. The right mining accessory is then secured in the same manner. The external front-end device then pushes the sliding table 2, which moves forward at a constant speed within the guide groove. Simultaneously, the two clamped mining accessories move backward at a constant speed to receive welding from the external welding machine.
[0027] The working principle of the fixing fixture for a mining parts welding machine provided by this utility model is as follows: When the fixing fixture is needed, the mining parts to be welded can be pre-judged to determine the welding point between the two mining parts. At this time, the torsion valve 10 can be turned in the forward and reverse directions, thereby causing the two worm gears 9 to rotate in the forward and reverse directions simultaneously. The rotation of the two worm gears 9 drives the rotating rod 41 to rotate through the worm wheel 8. The rotation directions of the two worm gears 9 are opposite, so the rotation directions of the two rotating rods 41 are also opposite. The left fixing platform 42 rotates around the central axis of the left rotating rod 41, and the right fixing platform 42 rotates around the central axis of the right rotating rod 41. Then, the mining parts to be welded can be placed on the support platform, and the side to be welded can be placed on the holding platform 43, so that the front side wall of the rear clamp 45 is close to the mining parts to be welded. As the fixing platform 42 rotates... The welding surfaces of the two components are aligned to form the welding line. Then, the tightening block on the front of the left longitudinal screw 6 is turned, causing the left longitudinal screw 6 to rotate. This moves the left front clamp 47 backward until its rear side contacts the front side of the mining component. Next, the tightening block on the upper side of the left vertical screw 7 is turned, causing the left rear clamp 45 and left front clamp 47 to move downward synchronously until their upper walls clamp the upper surface of the mining component, thus fixing the left mining component. The right mining component is then fixed in the same way. Finally, the sliding table 2 is pushed forward by the external front-end equipment. The sliding table 2 moves forward at a constant speed within the guide groove, causing the two clamped mining components to move backward synchronously at a constant speed, ready for welding by the external welding machine.
[0028] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
