[0031] Combine Figures 1 to 5 As shown, the present invention provides a petrochemical accessories positioning processing tool comprising a base 1 and a positioning block 2.

[0032] Combine Figures 1 to 5 As shown, the base 1 is evenly distributed with first rails 11 around its center, and the first rail 11 is a straight rail with one end pointing to the center of the base 1; the number of the positioning blocks 2 is the same as the number of the first rails 11, and each of the positioning blocks 2 is slidably assembled on the first rail 11; the number of the first rails 11 and the positioning blocks 2 is not less than three; at least three of the positioning blocks 2 slide synchronously on the corresponding first rails 11 until they contact the circular workpiece, and the distance between each positioning block 2 that contacts the circular workpiece and the center of the base 1 is the same, and the angle between the first rails 11 where adjacent positioning blocks 2 are located is less than 180 degrees.

[0033] In this embodiment, the circular workpiece is positioned by at least three positioning blocks 2 so that the center of the circular workpiece coincides with the center of the base 1, thereby achieving one-time tool alignment and center determination; the first tracks 11 where the positioning blocks 2 involved in positioning are located have angles less than 180 degrees with each other to ensure positioning stability; at least three positioning blocks 2 surrounding the center of the base 1 are selected for positioning, thereby improving the flexibility of clamping.

[0034] In some embodiments, combined Figure 1 、 Figure 2 As shown, the base 1 is fixedly equipped with a push rod 12, the number of the push rods 12 is the same as the number of the positioning blocks 2, and the pushing end of each push rod 12 is fixedly connected to a positioning block 2. The push rod 12 pushes the positioning block 2 to slide on the first track 11, and the sliding distance of the positioning block 2 on the first track 11 is precisely controlled by mechanical drive to achieve a better positioning effect.

[0035] In some embodiments, combined Figure 1 As shown, the petrochemical accessories positioning processing tooling also includes an external control center. The push rod 12 is an electric push rod. The external control center is electrically connected to each of the push rods 12. The participation of electronic components ensures the consistency of the movement of the positioning block 2 and improves the positioning accuracy.

[0036] In some embodiments, combined Figure 3 As shown, the base 1 is also provided with a second track 13, the second track 13 is circular, and a mounting plate 14 is slidably mounted on the second track 13. The first track 11, the push rod 12 and the positioning block 2 are all arranged on the mounting plate 14. The mounting plate 14 slides around the center of the base 1 on the second track 13, and the push rod 12 and the positioning block 2 slide on the second track 13 through the mounting plate 14, thereby realizing flexible adjustment of the position of the circular workpiece, further improving the flexibility of clamping.

[0037] In some embodiments, combined Figure 3 As shown, the number of the first rail 11, the push rod 12, the mounting plate 14 and the positioning block 2 are all three. Since the positions are adjustable, there is no need to retain extra options; the positioning of the circular workpiece can be completed by three positioning blocks 2 with flexible positions.

[0038] In some embodiments, combined Figure 3 、 Figure 4 As shown, an electromagnetic suction cup 3 is fixedly installed at the center of the base 1. The electromagnetic suction cup 3 is cylindrical, and one end of the second rail 13 contacts the cylindrical surface of the electromagnetic suction cup 3. After the positioning of the circular workpiece is completed, power can be turned on to make the electromagnetic suction cup 3 suck the circular workpiece tightly, thereby increasing the fixing effect.

[0039] In some embodiments, combined Figure 3 、 Figure 4 As shown, the second track 13 is a double track consisting of two circular single tracks. The interaction force between the second track 13 and the mounting plate 14 mainly occurs in the direction perpendicular to the second track 13. The double track design has a higher upper force line, which is beneficial to avoid track deformation.

[0040] In some embodiments, combined Figure 3 、 Figure 4 As shown, the first track 11 and the second track 13 are both slide rails, and the positioning block 2 and the mounting plate 14 are both slidably assembled on the first track 11 and the second track 13 through the clamping block, so the assembly relationship is more firm and the service life of the structure is longer.

[0041] In some embodiments, combined Figure 5As shown, the positioning block 2 is provided with a fractal vise, and the jaws of the fractal vise abut against the circular workpiece, which can effectively improve the contact stability between the positioning block 2 and the circular workpiece. At the same time, the outer contour of the circular workpiece is the same everywhere, and the deformation of the fractal vise on each positioning block 2 is consistent, which will not affect the accuracy of positioning.

[0042] In some embodiments, combined Figure 1 、 Figure 3 As shown, the base 1 is provided with positioning holes 15, and the number of the positioning holes 15 is at least two. The positioning holes 15 can be directly used for tool alignment to simplify the tool alignment process. At the same time, designing multiple positioning holes 15 can effectively avoid the obstruction problem and improve the tool alignment efficiency.

[0043] Working process: Place the circular workpiece near the center of the base 1, select at least three positioning blocks 2 to slide synchronously on the corresponding first track 11 until they contact the circular workpiece, and select the distance between each positioning block 2 and the center of the base 1 to always remain the same. When each positioning block 2 contacts the circular workpiece, the center of the circular workpiece coincides with the center of the base 1, and the center position of the circular workpiece is fixed, and positioning can be completed with only one tool setting.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
