However, the existing six-claw fixing structure will keep sliding when increasing the distance between each claw in order to adapt to the cavity of the volute workpiece. This will cause the wall surface of the workpiece to be dented when each claw slides and contacts the workpiece, and the dent will affect the effect of surrounding welding when the workpiece is rotated next.
[0004] In view of this, the present utility model is proposed. Utility Model Content

This is an existing technology, so it will not be described here.
[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a clamping structure is provided at the top of the base plate 22, and the clamping structure includes an adapter rod 31, a pulley 34 and a fixed plate 47. The adapter rod 31 is fixedly connected to the top of the slider 33, the pulley 34 and the adapter rod 31 are slidably connected, and the fixed plate 47 is movably connected to the top of the adapter rod 31. The clamping structure can prevent the wall of the workpiece from being damaged during welding.
[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the adapting rod 31 is a rectangular tube with an inverted U-shaped section, the pulley 34 is slidably connected in the cavity of the adapting rod 31, the section of the fixing plate 47 is an isosceles triangle, the pulley 34 is cylindrical, and the clamping structure also includes a slide groove 32 and a slider 33. The slide groove 32 is symmetrically opened at the top of the adapting rod 31, and the slider 33 is slidably connected at the top of the adapting rod 31. The slider 33 is also a rectangular tube with an inverted U-shaped section. The pulley 34 is rotatably connected in the cavity of the slider 33. The bottom of the slider 33 can pass through the symmetrical slide grooves 32, and the top arc wall of the pulley 34 can contact the top of the cavity of the adapting rod 31. The clamping structure also includes a force block 40, a force distribution plate 41, a spring plate 42, a plunger 43, a support plate 44, and a slow wheel 45. 5 and buffer block 46, the force block 40 is fixedly connected to the top of the slider 33, the fixed plate 47 is rotatably connected to the top of the force block 40, the force distribution plate 41 is symmetrically fixedly connected to the front wall of the force block 40, the spring plate 42 is fixedly connected between the symmetrical force distribution plates 41, the piston 43 is rotatably connected between the symmetrical force distribution plates 41, the support plate 44 is symmetrically fixedly connected to the front and rear walls of the piston 43, the slow wheel 45 is rotatably connected to the wall of one support plate 44, the buffer block 46 is fixedly connected to the top of the other support plate 44, the wall of the spring plate 42 is also fixedly connected to the force block 40, the bottom of the support plate 44 in the direction of the slow wheel 45 is elastically connected to the top of the spring plate 42, the top of the symmetrical support plate 44 is flush, and the cross section of the buffer block 46 is trapezoidal;
[0028] During specific use, the pulley 34 is electrically connected to the power supply, and the pulley 34 is also connected to a control console that can control the position of the pulley 34, which is not shown in the figure. The volute workpiece is placed vertically above the rotating column 30 and the slider 33 is adjusted to a spacing that matches the size of the workpiece cavity. When adjusting the spacing of the slider 33, all the pulleys 34 are controlled by the console to slide along the cavity of the adapter rod 31. At this time, the pulley 34 can drive the slider 33 to slide on the top of the adapter rod 31. When the slider 33 slides, it will drive the force block 40 to move at the same time. The force block 40 can drive all the structures on its top to move at the same time.

The bottom of the support plate 44 in the direction of the slow wheel 45 is connected to the top of the spring plate 42 through a spring. When the workpiece contacts the slow wheel 45, it will bring downward pressure to the slow wheel 45. At this time, the slow wheel 45 will contact the spring plate 42 due to the rotation of the piston 43. At the same time, the buffer block 46 will move to contact the bottom of the workpiece due to the rotation of the piston 43.

The material of the fixed plate 47, the slow wheel 45 and the buffer block 46 are all elastic rubber materials;
[0029] To summarize, by setting up a clamping structure, the workpiece can be protected from damage when the device fixes the workpiece, because the clamping structure fixes the workpiece position by supporting the bottom of the workpiece and positioning it in the workpiece cavity, and in this process does not cause direct damage to the workpiece when contacting the workpiece. Therefore, compared with the commonly used existing technology, this solution can avoid damage to the workpiece when in use.
[0030] like Figure 3 , Figure 4 and Figure 5 As shown, the clamping structure also includes an auxiliary plate 48, a rotating groove 49 and a clamping block 50. The auxiliary plate 48 is fixedly connected to the rear wall of the fixed plate 47. The rotating grooves 49 are symmetrically arranged on the two side walls of the auxiliary plate 48. The clamping block 50 is rotatably connected in the rotating grooves 49. The rotating grooves 49 can adapt to the size of the clamping block 50. The auxiliary plate 48 is a rectangular plate. The surrounding walls of the rotating column 30 are provided with a plurality of clamping structures. The plurality of clamping structures are distributed in a circular array around the rotating column 30.
[0031] When in use, the fixing plate 47 can be turned over 90 degrees on the top of the force-bearing block 40, turning the original vertical state into a horizontal state. When the fixing plate 47 is in the vertical state, turning the clamping block 50 into a vertical state can fix the angle of the fixing plate 47, because the clamping block 50 will contact the wall surface of the force-bearing block 40 to hold and fix the fixing plate 47. Before the fixing plate 47 is turned over 90 degrees, the clamping block 50 needs to be turned over to a horizontal state. At this time, the fixing plate 47 is turned over again, and the auxiliary plate 48 will hold the horizontal fixing plate 47 to complete the fixing of the fixing plate 47 in a horizontal state. At this time, the upward wall surface of the fixing plate 47 can contact the workpiece without an opening at the bottom, and the workpiece can also be fixed vertically on the device.
[0032] In summary, by providing a flippable fixing plate 47, more types of workpieces can be fixed, because the fixing plate 47 adapts to different workpieces by flipping to different states, and after the workpiece is fixed, it can also ensure that the workpiece will not shift during rotation, thereby increasing the scope of application of the device.
[0033] Working principle: Place the volute workpiece vertically above the rotating column 30 and adjust the slider 33 to a spacing that matches the size of the workpiece cavity. When adjusting the spacing of the slider 33, all the pulleys 34 are controlled by the console to slide along the cavity of the adapter rod 31. At this time, the pulley 34 can drive the slider 33 to slide on the top of the adapter rod 31. When the slider 33 slides, it will drive the force block 40 to move at the same time. The force block 40 can drive all the structures on its top to move at the same time. When the position of the workpiece cavity and the slider 33 are aligned, the workpiece is directly placed on the slider 33. At the top, the front wall of the fixing plate 47 can be aligned with the inner wall of the workpiece cavity, and the bottom of the workpiece will first contact the slow wheel 45. The bottom of the support plate 44 in the direction of the slow wheel 45 is connected to the top of the spring plate 42 through a spring. When the workpiece contacts the slow wheel 45, a downward pressure is applied to the slow wheel 45. At this time, the slow wheel 45 will contact the spring plate 42 due to the rotation of the piston 43. At the same time, the buffer block 46 will move to contact the bottom of the workpiece due to the rotation of the piston 43. At this time, the buffer block 46 and the slow wheel 45 are kept on the same horizontal line to support the bottom of the workpiece.
