[0022] See also Figure 1-3 , the utility model provides a technical solution: a circular centering scriber, comprising a scribing workbench 2 and a scribing assembly;

[0023] The marking assembly is arranged on the marking workbench 2. The marking assembly includes a triangular positioning seat 3, a base 5, two guide rods 6, a sliding plate 8, two springs 9, two disc parts 10, a marking steel bar 11 and a sliding groove 12. The triangular positioning seat 3 is welded on the marking workbench 2. The triangular inner angle of the triangular positioning seat 3 is 120°. The marking steel bar 11 is welded to the middle part of the triangular positioning seat 3. The base 5 slides along the surface of the marking steel bar 11. There is a marking groove on the marking steel bar 11.

[0024] The two guide rods 6 are both welded to the right side of the base 5 , and the two disc members 10 are respectively welded to the right side of the corresponding guide rods 6 .

[0025] The two springs 9 are respectively welded to the left side of the disc member 10 , and the two springs 9 are both welded to the sliding plate 8 . The two guide rods 6 slide through the sliding plate 8 , and a sliding groove 12 is provided on the surface of the sliding plate 8 .

[0026] The marking steel bar 11 slides along the inside of the sliding groove 12 , and the upper end surface of the sliding plate 8 is threadedly connected to the limiting bolt 2 13 , and the lower end of the limiting bolt 2 13 contacts the upper end of the marking steel bar 11 .

[0027] A pressing plate 4 is provided at the upper end of the base 5 , and both ends of the pressing plate 4 are threadedly connected to a limiting bolt 7 , and the lower surface of the pressing plate 4 contacts the upper surface of the ruled steel bar 11 .

[0028] A circular workpiece 1 is disposed between the triangular positioning seat 3 and the base 5 . The surface of the triangular positioning seat 3 contacts the circular workpiece 1 , and the surface of the base 5 contacts the circular workpiece 1 .

[0029] When it is necessary to mark circular workpieces in batches;

[0030] First, the limiting bolt 13 is driven to move by an external force, and the movement of the limiting bolt 13 loosens the positional relationship between the sliding plate 8 and the marking steel bar 11. Then, the base 5 is driven to move by an external force, and the movement of the base 5 drives the two guide rods 6 to move, and the movement of the two guide rods 6 drives the corresponding disc parts 10 to move, and the movement of the two disc parts 10 drives the corresponding springs 9 to move respectively, and the movement of the two springs 9 drives the sliding plate 8 to move, and the base 5 moves until it contacts the circular workpiece 1. At this moment, the triangular positioning seat 3 contacts the circular workpiece 1.

[0031] Secondly, the sliding plate 8 is driven to move to a suitable position by an external force, and then the limiting bolt 2 13 is driven to move and tighten the positional relationship between the marking steel bar 11 and the sliding plate 8 by an external force.

[0032] It should be noted that the appropriate position of the sliding plate 8 needs to ensure that when the base 5 moves to the right and contacts the sliding plate 8, the circular workpiece 1 can leave between the triangular positioning seat 3 and the base 5, and the two springs 9 drive the base 5 to squeeze the surface of the circular workpiece 1.

[0033] Finally, the surface of the circular workpiece 1 is marked along the marking groove in the middle of the marking steel bar 11. Subsequently, the base 5 is driven to move by an external force so that there is a sufficient distance between the base 5 and the triangular positioning seat 3. The movement of the base 5 drives the two guide rods 6 to move, and the movement of the two guide rods 6 drives the corresponding disc parts 10 to move. The movement of the two disc parts 10 drives the corresponding springs 9 to stretch. Subsequently, the circular workpiece 1 is driven by an external force to move away from between the triangular positioning seat 3 and the base 5. Subsequently, the new circular workpiece 1 is driven by an external force to move between the circular workpiece 1 and the base 5. Subsequently, the base 5 is released, and the two springs 9 are reset to drive the base 5 to move and extrude the new circular workpiece 1, calibrate the position of the circular workpiece 1, and subsequently, mark the new circular workpiece 1.

[0034] By setting the triangular positioning seat 3, base 5 and marking steel bar 11 in the marking assembly, after the triangular positioning seat 3 and the base 5 are clamped and positioned, marking can be performed along the marking groove in the middle of the marking steel bar 11. The entire marking process does not require finding and leaving rivet points on the circular workpiece 1, thereby not only ensuring the beauty of the marked circular workpiece 1, but also avoiding the problem of workpiece scrapping due to the need for rivet points, reducing the difficulty of the entire marking, and improving the work efficiency during batch marking.

[0035] By setting two springs 9 in the marking assembly, when the circular workpiece 1 needs to be replaced, it is only necessary to drive the base 5 to move, stretch the spring 9, and then replace the circular workpiece 1. Subsequently, the base 5 is released, and the two springs 9 automatically reset to position the new circular workpiece 1, eliminating the step of driving the base 5 to move a second time, thereby improving the work efficiency during batch marking.

[0036] The triangular positioning seat 3 is an integrally formed workpiece with little deformation. The straight steel bar is placed in the groove and a cold welding process is used to prevent the device from being deformed and affecting the accuracy of the device. After the splicing is completed, calibration is performed to ensure the accuracy of the device. A movable base 5 is added to adjust to circular materials of different sizes through sliding. The triangular positioning seats on both sides are close to the circular workpiece to ensure stability during marking. After positioning on both sides, they have a calibration function. The device is simple and convenient to operate, improves work efficiency in mechanical processing, ensures the beauty of the workpiece, improves quality, and reduces the risk of processing errors.

[0037] Working principle:

[0038] When it is necessary to mark circular workpieces in batches;

[0039] First, the limiting bolt 13 is driven to move by an external force, and the movement of the limiting bolt 13 loosens the positional relationship between the sliding plate 8 and the marking steel bar 11. Then, the base 5 is driven to move by an external force, and the movement of the base 5 drives the two guide rods 6 to move, and the movement of the two guide rods 6 drives the corresponding disc parts 10 to move, and the movement of the two disc parts 10 drives the corresponding springs 9 to move respectively, and the movement of the two springs 9 drives the sliding plate 8 to move, and the base 5 moves until it contacts the circular workpiece 1. At this moment, the triangular positioning seat 3 contacts the circular workpiece 1.

[0040] Secondly, the sliding plate 8 is driven to move to a suitable position by an external force, and then the limiting bolt 2 13 is driven to move and tighten the positional relationship between the marking steel bar 11 and the sliding plate 8 by an external force.

[0041] Finally, the surface of the circular workpiece 1 is marked along the marking groove in the middle of the marking steel bar 11. Subsequently, the base 5 is driven to move by an external force so that there is a sufficient distance between the base 5 and the triangular positioning seat 3. The movement of the base 5 drives the two guide rods 6 to move, and the movement of the two guide rods 6 drives the corresponding disc parts 10 to move. The movement of the two disc parts 10 drives the corresponding springs 9 to stretch. Subsequently, the circular workpiece 1 is driven by an external force to move away from between the triangular positioning seat 3 and the base 5. Subsequently, the new circular workpiece 1 is driven by an external force to move between the circular workpiece 1 and the base 5. Subsequently, the base 5 is released, and the two springs 9 are reset to drive the base 5 to move and extrude the new circular workpiece 1, calibrate the position of the circular workpiece 1, and subsequently, mark the new circular workpiece 1.

Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
