[0014] In order to make the technical means for realizing the present invention, the creative features, the purpose and the effect easily understood, the present invention is further explained below in conjunction with specific diagrams. In the description of the present invention, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, an integral connection or a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be internal communication between two components.
[0015] Example 1
[0016] like Figure 1 - Figure 3The shown positioning mechanism for an arc-shaped bevel steel plate includes a base plate 1, a support plate 2 is connected to the top of the base plate 1, a bracket 3 is slidably connected to one side of the support plate 2, and a number of rollers 8 are installed on the bracket 3. The rollers 8 can facilitate the movement of the arc-shaped steel plate. The top of the support plate 2 is connected to a top plate 7, and a bevel tool 9 is installed between the top plate 7 and the bracket 3. One end of the bevel tool 9 is connected to a servo motor (not marked in the figure). The servo motor can drive the bevel tool 9 to operate and perform bevel processing on the arc-shaped steel plate. A roller 12 is installed on one side of the bracket 3. The roller 12 is set at the end, which can facilitate the arc-shaped steel plate to slide out of the bracket 3, making the bevel processing of the arc-shaped steel plate more convenient. The bracket 3 is provided with a positioning mechanism for positioning the arc-shaped plate undergoing bevel operation.
[0017] In this embodiment, the positioning mechanism includes a positioning pin 11, the outer wall of the positioning pin 11 is provided with a positioning pin sleeve 10, the bottom end of the positioning pin 11 is provided with a limiting groove 17, the top of the bracket 3 is provided with a positioning groove 14 corresponding to the positioning pin 11, and one side of the bracket 3 is provided with a limiting hole 15, the positioning groove 14 is connected to the inside of the limiting hole 15, and one side of the bracket 3 is provided with a limiting bolt 16 corresponding to the limiting hole 15. A bearing 18 is installed between the inner wall of the positioning pin sleeve 10 and the outer wall of the positioning pin 11. The lower end of the positioning pin 11 is inserted into the positioning groove 14 and rotated to position. The pin 11 aligns the limiting groove 17 with the limiting hole 15, and then the limiting bolt 16 is screwed into the limiting hole 15. The limiting bolt 16 can be tightened to fix the positioning pin 11, and then the positioning pin sleeve 10 is put on the positioning pin 11. The number of positioning pin sleeves 10 can be selected according to the thickness of the steel plate. A maximum of three positioning pin sleeves 10 can be set. When beveling the curved steel plate, the outer wall of the curved steel plate is pressed against the outer wall of the positioning pin sleeve 10. When the curved steel plate is rotated, the outer wall of the curved steel plate is always in contact with the positioning pin sleeve 10, which can avoid the position of the curved steel plate from shifting during beveling.
[0018] Preferably, there are multiple positioning grooves 14 and limiting holes 15, and each limiting hole 15 is set corresponding to the positioning groove 14. The positioning pin 11 can be inserted into the positioning groove 14 at different positions according to the arc steel plates with different curvatures to achieve positioning of the arc steel plates with different curvatures.
[0019] Example 2
[0020] A further improvement on the basis of Example 1 is that Figure 1The shown embodiment is a positioning mechanism for arc-shaped grooved steel plates, and the lifting mechanism includes an electric push rod 4, the fixed end of the electric push rod 4 is connected to the top of the base plate 1, the telescopic end of the electric push rod 4 is connected to the bottom of the bracket 3, both sides of the bracket 3 are connected with sliders 5, both sides of the support plate 2 are connected with guide rails 6, and the slider 5 is provided with a slide groove 13, which is slidably connected to the guide rail 6. By starting the electric push rod 4, the bracket 3 can be driven to rise and fall, so that the distance between the bracket 3 and the top plate 7 can be adjusted, which is convenient for beveling arc-shaped steel plates of different sizes.
[0021] The process flow and working principle of the present invention are as follows: before beveling the curved steel plate, the lower end of the locating pin 11 is first inserted into the locating groove 14, the locating pin 11 is rotated to align the limiting groove 17 with the limiting hole 15, and then the limiting bolt 16 is screwed into the limiting hole 15, and the limiting bolt 16 can be tightened to fix the locating pin 11, and then the locating pin sleeve 10 is sleeved on the locating pin 11. The number of locating pin sleeves 10 can be selected according to the thickness of the steel plate, and up to three locating pin sleeves 10 can be sleeved. The locating grooves 14 in different positions can be selected according to the curvature of the curved steel plate. When beveling the curved steel plate, the outer wall of the curved steel plate is pressed against the outer wall of the locating pin sleeve 10. When the curved steel plate is rotated, due to the rotational connection between the positioning shaft sleeve 10 and the locating pin 11, the outer wall of the curved steel plate is always in contact with the locating pin sleeve 10, which can avoid the position of the curved steel plate from shifting during beveling, and has the effect of improving the welding quality and structural stability of the curved steel plate.
