[0021] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, terms such as "installation", "provided with", "connection", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0022] Embodiment 1:
[0023] As shown in the attached Figures 1-3 figures, as a preferred implementation manner, on the basis of the above manner, further, it includes a mounting base plate 1. There are positioning blocks 7 arranged on the mounting base plate 1, and the positioning blocks 7 are symmetrically distributed on the left and right sides of the mounting base plate 1. A positioning hole 4 is opened inside the positioning block 7, and an operating rod 6 is screwed inside the positioning hole 4. One side of the operating rod 6 is in a "cross" shape structure, and the other side of the operating rod 6 is connected with a clamping plate 12. A moving block 14 is arranged at the lower end of the clamping plate 12, and the moving blocks 14 are symmetrically distributed at the lower left and right ends of the clamping plate 12. A moving groove 2 is opened on the mounting base plate 1, and the position of the moving groove 2 corresponds to that of the moving block 14. A fixing column 10 is arranged on the upper side of the clamping plate 12, and a pressing plate 9 is connected to the upper side of the fixing column 10. A fixing hole 13 is opened inside the pressing plate 9, and a locking block 11 is arranged on the upper side of the pressing plate 9. Mounting holes 5 are opened on the mounting base plate 1, and the mounting holes 5 are located at the four corners of the mounting base plate 1.
[0024] Embodiment 2:
[0025] The solution in Embodiment 1 will be further introduced below in combination with the specific working mode. See the following description for details.
[0026] As shown in the attached Figure 2As shown, as a preferred embodiment, on the basis of the above method, further, the moving groove 2 is in an inverted "T" shape, and the outer dimensions of the moving groove 2 match those of the moving block 14. The moving block 14 can move along the direction of the moving groove 2, and the inverted "T" shaped moving groove 2 can prevent the moving block 14 from easily disengaging from the moving groove 2 in the vertical direction, enabling the moving groove 2 to restrict the rotation of the clamping plate 12 and only move along the moving direction of the operating rod 6; Ball bearings 3 are arranged inside the moving groove 2, and the ball bearings 3 are evenly distributed inside the large end of the moving groove 2 in a straight line direction. The friction between the moving groove 2 and the moving block 14 can be reduced through the ball bearings 3, enabling the moving block 14 to move more conveniently along the moving groove 2; The pressing plate 9 is in an inverted "L" shape and is sleeved outside the small end of the fixed column 10. The inverted "L" shaped pressing plate 9 can conveniently press down the top surface of the flange, restricting the movement of the flange in the vertical direction and better fixing the flange.
[0027] As shown in the Figures 1-3 As shown, as a preferred embodiment, on the basis of the above method, further, four support rods 8 are arranged between the positioning block 7 and the clamping plate 12, and the support rods 8 are distributed at the four corner positions on the back of the clamping plate 12. The support rods 8 can evenly support the four corner positions on the back of the clamping plate 12, making the force on the clamping plate 12 more uniform and better clamping the flange in the middle for processing; The support rod 8 is a telescopic structure, and the telescopic length of the support rod 8 is greater than the moving distance of the clamping plate 12. The telescopic support rod 8 can expand and contract as the clamping plate 12 moves. When the clamping plate 12 moves to a suitable position, the bolt on the support rod 8 can be tightened to fix the support rod 8, enabling it to stably support the clamping plate 12 and ensuring that the clamping plate 12 can stably clamp the flange, avoiding the clamping plate 12 from moving to both sides due to the vibration during flange processing.
[0028] As shown in the Figures 1-2 As shown, as a preferred embodiment, on the basis of the above method, further, the fixed column 10 is in an inverted "T" shape, and the area of the large end of the fixed column 10 is larger than the cross-sectional area of the fixing hole 13. External threads are provided on the small end of the fixed column 10, and internal threads are provided inside the locking block 11. The external threads of the fixed column 10 match the internal threads of the locking block 11. When the pressing plate 9 is sleeved outside the small end of the fixed column 10 through the fixing hole 13, the large end of the fixed column 10 can support the pressing plate 9, and the pressing plate 9 can be fixed through the threaded connection between the small end of the fixed column 10 and the locking block 11, enabling it to play a role in pressing the top of the flange.
[0029] Working principle: First, place the mounting base plate 1 on the processing table and fix it to the processing platform through the mounting holes 5 on the mounting base plate 1. Place the flange to be processed in the middle position of the mounting base plate 1. At the same time, turn the operating rods 6 on both sides. The clamping plates 12 on both sides are pushed by the operating rods 6 to move towards the middle flange. The moving blocks 14 on the lower side of the clamping plates 12 can move along the moving grooves 2. The moving grooves 2 limit the rotation of the clamping plates 12 and make them move along the moving direction of the operating rods 6. The balls 3 inside the moving grooves 2 can facilitate the better movement of the moving blocks 14. The position of the operating rods 6 can be fixed through the threaded connection between the positioning holes 4 inside the positioning blocks 7 and the operating rods 6. Then, lock the bolts on the support rods 8 in sequence to fix the positions of the support rods 8 and make them stably support the clamping plates 12. Next, install the pressing plate 9 onto the fixing column 10 through the fixing holes 13 inside it, and fix the position of the pressing plate 9 through the threaded connection between the locking block 11 and the fixing column 10, so that the pressing plate 9 presses down on the top of the flange to better fix the flange.
[0030] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed within the present utility model. Any reference signs in the claims should not be regarded as limiting the claims involved.
