[0031] In order to make the solutions and advantages of the present invention clear and specific, the following is a complete and clear description of the various parts and overall embodiments of the present invention in conjunction with the accompanying drawings.

[0032] It should be noted that the "positioning" mentioned in this embodiment can refer to the sliding fit between parts, or the close contact between parts; "connection" refers to rivet connection, cylindrical pin connection or threaded connection, which can be understood by engineering and technical personnel based on the actual connection situation.

[0033] Combination Figure 1-8 The multifunctional punching and marking tool comprises: a punching mechanism, a rotary guide mechanism, and a positioning mechanism.

[0034] The punching mechanism comprises: a punch 2, a sleeve 8, a pull rod 10, a pressure spring 11, a nut 12, a first cylindrical pin 13, a knob 14, a baffle 16, a rolling nut 20, and an ejector pin 21.

[0035] The rotary guide mechanism comprises: a positioning plate 1, a deep groove ball bearing 3, a ball 4, a guide plate 5, a ball 6, an angle frame 7, a rivet 22, and a convex ring 23.

[0036] The positioning mechanism includes: a cam frame 15 , a second cylindrical pin 17 , a spring 18 , and a push rod 19 .

[0037] In the punching mechanism, the punch 2 and the pull rod 10 are respectively positioned in the sleeve 8, and the punch 2 and the pull rod 10 are tightly connected. A positioning pin 9 is also connected to the side of the lower end of the pull rod 10, and the positioning pin 9 is positioned in the groove of the sleeve 8. A pressure spring 11 is installed on the pull rod 10, and the pressure spring 11 is pressed by a nut 12 connected to the sleeve 8. A knob 14 is connected to the pull rod 10 through a first cylindrical pin 13, and a rolling nut 20 is connected to the lower side of the sleeve 8 through an ejector pin 21. Rotating the rolling nut 20 can make the ejector pin 21 press the angle disc 7 or loosen it.

[0038] The rotary guide mechanism is as follows Figure 1 As shown, Figure 1 The two positioning plates 1 at the left and right ends are connected to the two guide plates 5 by four rivets 22. Figure 3 The guide plate 5 is positioned at the left and right sides by the positioning plate 1. At the same time, four balls 4 are positioned at the lower ends of the positioning plates 1 at both ends to reduce the friction between the tool and the workpiece when the tool is in use. Figure 3 The guide plates 5 on both sides are respectively positioned with three balls 6 in the V-shaped shape formed by the angle frame 7 on both sides to reduce the friction of the angle frame 7 sliding on the guide plates 5 on both sides.

[0039] Then a deep groove ball bearing 3 is installed in the center of the angle frame 7 to facilitate the rotation of the sleeve 8 in the angle frame 7. An angle is engraved on the upper end surface of the angle frame 7. At the same time, a convex ring 23 made of transparent glass with a magnifying function is connected to the upper end surface of the angle frame 7 to facilitate the positioning of the angle when the sleeve 8 is rotated to a certain angle.

[0040] The positioning mechanism comprises Figure 2 In the embodiment, the second cylindrical pin 17 connects the cam frame 15 to the groove on one side of the angle frame 7, against the push rod 19 pressed on the pressure spring 18.

[0041] The specific implementation method here only lists a method of marking the center line of the cross and punching 6 points evenly distributed on the diameter of φ100mm with the intersection of the cross as the center. Other marking and punching methods can be flexibly used according to actual conditions;

[0042] First, use the multifunctional punching and marking tool to find and mark the two center lines of the workpiece, then place the multifunctional punching and marking tool on the workpiece to align the scale lines on the positioning plates 1 at both ends with the marks, then push the cam frame 15 of a positioning mechanism outward to loosen the positioned push rod 19, then push the punching mechanism along the guide plate 5 of the rotating guide mechanism to one end of the tool, then rotate the knob 14 to make the positioning pin 9 that is initially in the horizontal groove above the sleeve 8 fall along the long groove on the sleeve 8, at this time, press the knob 14 with your palm and drag the punching mechanism along the guide plate 5 of the rotating guide mechanism to the other end of the tool, at this time, one marking is completed, and the marking method for the other direction is the same.

[0043] After all the cross lines are marked, align the 0 scale lines on the positioning plates 1 at both ends of the tool with any of the marked lines. At this time, pull the knob 14 upward and rotate it so that the positioning pin 9 is in the horizontal groove above the sleeve 8. Then drag the punching mechanism so that the pointer at the lower end of the sleeve 8 is aligned with another marked line. Then, move the cam frame 15 inward so that the push rod 19 presses against the inner side of the guide plate 5 in a V-shaped position to position the rotating guide part. Then rotate the knob 14 to place the positioning pin 9 in the horizontal groove above the sleeve 8 in the long groove and pull it up to the maximum stroke. Then release the knob 14. At this time, as the positioning pin 9 falls, a cross intersection is punched on the workpiece.

[0044] Then, according to the above method, the cam frame 15 of the other rotating guide mechanism is pushed outward to loosen the positioned push rod 19, and then, with the coordinates on the tool at the point just punched as the center, the punching mechanism is dragged along the guide plate 5 of the rotating guide mechanism to support half of the diameter of φ100mm, and then the cam frame 15 is pushed inward to make the push rod 19 press against the inner V-shaped guide part of the guide plate 5 to position the rotating guide part, and then the punching mechanism of the point just punched is pressed by hand, and the other punching mechanism is dragged around it with it as the center point, and the angle scale on the punching mechanism of the point just punched is observed. When it is just turned to 60°, the rolling nut 20 of the punching mechanism of the point just punched is pushed again to make the push pin 21 press against the punch The upper end of the punching mechanism positions the rotating part of the rotary guide mechanism, and then the knob 14 of another punching mechanism is rotated to put the positioning pin 9 in the transverse groove above the sleeve 8 in the long groove and pull it up to the maximum stroke, and then the knob 14 is released. At this time, as the positioning pin 9 falls, one of the 6 points evenly distributed on the diameter of φ100mm is punched on the workpiece, and then the rolling nut 20 of the punching mechanism that has just punched is turned to make the ejector 21 release the upper end of the punching mechanism to position the rotating part of the rotary guide mechanism, and then the knob 14 of another punching mechanism is pulled to make the positioning pin 9 in the transverse groove above the sleeve 8, and then the other points are done by analogy to complete the punching of 6 points evenly distributed on the diameter of φ100mm.
