Description

Technical Field

[0001] The utility model belongs to the technical field of stamping machines, in particular to a precise stamping positioning tool and a stamping mechanism. Background Art

[0002] Seals are stationery used to print on documents to indicate identification or signature. Generally, seals are first dipped in paint and then printed. Some seals are not dipped in paint and are directly printed on a flat surface to produce a concave and convex mark, which is called a steel seal. In addition, some are printed on wax or wax, or wax seals on envelopes. With the historical development of seals, the materials used to make seals include jade, metal, wood, and stone.

[0003] With the development of the seal industry, enterprises, institutions and government departments have strict requirements for stamping some particularly important documents, and even a certain word on the seal must be accurately stamped on a certain word on the document.

[0004] In Chinese patent document CN212148063U, a seal for accurate use is disclosed, comprising a seal body, a positioning structure and a comparison structure, wherein a limiting groove is provided on the side wall of the seal body, and a limiting portion is provided on the inner side wall of the positioning structure, the size of the limiting portion being adapted to the size of the limiting groove; the positioning structure is a cubic structure, a through hole is provided on any surface of the positioning structure, the diameter of the through hole is adapted to the outer diameter of the seal body, and the thickness of the positioning structure is less than the thickness of the seal body; the comparison structure is an arc-shaped structure, the comparison structure is fixed on the top surface of the seal body, and the top surface of the seal body is a side of the seal body without a font engraved thereon; the shape of the comparison structure is the same as the shape of the font engraved on the bottom surface of the seal body, the position of the comparison structure is opposite to the position of the font, the line connecting the two ends of the comparison structure and its center constitutes a first angle, and the angle bisector of the first angle is perpendicular to a group of opposite side walls of the positioning structure.

[0005] Although the above technical solution can predict the position of the seal more accurately, it still cannot ensure that a certain word on the seal is accurately pressed on a certain word on the document, and this technical solution is only applicable to a single specific seal when positioning.

[0006] Therefore, it is necessary to develop a new seal positioning tool and seal mechanism that can accurately stamp a certain word of the seal on a certain word of the document, and the operation is easy and does not rely on technical experience. Utility Model Content

[0007] The technical problem to be solved by the utility model is to provide an accurate stamping positioning tool and a stamping mechanism for accurately determining the stamping position when stamping with a stamping device or a bare stamp.

[0008] In order to solve the above technical problems, the technical solution adopted by the utility model is: a precise stamp positioning tool, comprising an inner positioning piece and an outer positioning frame; the inner positioning piece is located in the outer positioning frame, and the inner positioning piece and the outer positioning frame are movably assembled with each other; the inner positioning piece has an upper surface in contact with the stamp, and a transparent middle layer is provided between the upper surface and the lower surface of the inner positioning piece, and the lower surface is used to contact the piece to be stamped.

[0009] The outer positioning frame is used to guide the positioning of the stamp, and the inner positioning piece is used to simulate the real effect after the stamp is dropped, replacing the old solution of reducing the aiming range; in the above technical solution, the inner positioning piece and the outer positioning frame are movably assembled with each other, so that the inner positioning piece and the outer edge of the outer positioning frame fit each other and can be freely disassembled. The inner positioning piece is taken out by pressing the outer positioning frame, so that the inner positioning piece can be removed after pre-positioning to press the stamp, which increases the portability during use. The transparent middle layer between the upper surface and the lower surface of the inner positioning piece makes it easy for the user to see the precise alignment position of the seal and the document to be stamped through the inner positioning piece, and can accurately align a certain word of the seal on a certain word of the document to be stamped.

[0010] Preferably, the outer positioning frame has a fitting and disengagement hole, and the fitting and disengagement hole forms a disengagement cavity between the inner positioning piece and the outer positioning frame.

[0011] The design of being out of the cavity allows the hand to be more naturally extended between the inner positioning piece and the outer positioning frame during operation, making it easier to place or take the inner positioning piece and avoiding the inner positioning piece and the outer positioning frame fitting too closely to affect the mobility during assembly.

[0012] Preferably, the outer positioning frame has an inner peripheral edge that fits and movably fits with the inner positioning piece, and the area between the inner peripheral edge and the outer peripheral edge of the outer positioning frame is at least greater than 5 cm 2 .

[0013] The inner edge of the outer positioning frame is designed to fit the inner positioning piece, which reduces the sliding of the inner positioning piece in the outer positioning frame during the pre-positioning of the stamp, and enhances the accuracy of positioning. The area design between the inner edge and the outer edge of the outer positioning frame increases the friction between the outer positioning frame and the document to be stamped, which is crucial for maintaining the stability of the inner positioning piece in the predetermined position, especially when dealing with heavier stamps.

[0014] Preferably, the thickness of the inner peripheral edge is the same as the thickness of the transparent intermediate layer.

[0015] This design ensures the balance and consistency of the inner positioning piece inside the outer positioning frame, which is particularly important for maintaining the level and pressure distribution when stamping, and preventing tilt or uneven pressure from occurring during the stamping process, which can affect the stamping effect. At the same time, it can also ensure the structural stability and durability of the entire positioning tool during use, making the inner positioning piece smoother when moving or adjusting, and avoiding jamming or obstruction caused by different thicknesses. This allows users to stamp only once on the inner positioning piece, or even take out the inner positioning piece separately, so that its outer contour coincides with the outer contour of the seal tube and press down to stamp to obtain the seal mold.

[0016] It should be noted that in the above technical solution, the thickness is emphasized because without a certain thickness, the two will not fit tightly. According to the inventor's multiple experiments and technical verification experience, the thickness should not be less than 1 mm.

[0017] Preferably, one end of the inner positioning piece has an arc-shaped surrounding edge, and the other end has a straight surrounding edge.

[0018] The arc-shaped edge at one end of the inner positioning piece and the straight edge at the other end not only optimize the appearance of the inner positioning piece, but also provide users with more obvious direction indications, making it easier for users to distinguish the front and back directions of the inner positioning piece, avoid direction errors when placing the seal, and ensure that the seal pattern is correctly aligned with the target position. It effectively reduces stamping errors caused by improper operation and is suitable for various occasions that require high-precision and fast stamping operations; at the same time, this structural design is also designed to match the shape of the seal jacket in the positioning tool and the seal mechanism. The contour of the inner positioning piece is designed according to the outer contour of the stamping equipment.

[0019] Preferably, the seal mechanism of the positioning tool includes a seal outer sleeve, a seal inner sleeve is arranged inside the seal outer sleeve, and a seal is installed in the seal inner sleeve; when the seal extends out of the seal outer sleeve, it contacts the upper surface of the inner positioning piece in the precise stamp positioning tool.

[0020] The seal cover is the outer protective shell of the seal mechanism, providing basic protection and support for the seal. The seal inner cover is used to fix the seal itself, and it carries the seal to move up and down in the vertical direction, so that it will not fall off during the action. The outer extension of the seal mechanism contacts the upper surface of the inner positioning piece, ensuring high consistency and alignment accuracy during the stamping process. This synergy makes the entire stamping process smoother and more controllable, and improves the quality of stamping.

[0021] Preferably, the seal outer sleeve includes a seal tube, and the seal tube movable cover is movably mounted on the seal tube; the seal inner sleeve is located in the seal tube, and the seal tube movable cover drives the seal inner sleeve to move up and down along the vertical direction of the seal tube.

[0022] The seal cylinder is the main part of the seal cover, which is used to fix and protect the inner seal sleeve and seal. The seal cylinder movable cover is a movable cover that is mounted on the seal cylinder and can move from top to bottom along the vertical direction of the seal cylinder. The design of the seal cylinder movable cover allows the user to control the up and down movement of the seal through simple external operations. This control method improves the flexibility and accuracy of the stamping process, and the user can adjust the pressure and contact depth of the seal as needed.

[0023] Before stamping, make sure the seal cylinder cover is in the initial position and the seal inner sleeve and seal are at the appropriate height inside the seal cylinder. Adjust the position of the seal inner sleeve by moving the seal cylinder cover so that the seal reaches the required stamping height. This step is completed through simple external operation, and the user can observe the movement of the seal in real time and make precise adjustments. After stamping is completed, the seal inner sleeve is returned to its original position by reversing the seal cylinder cover to avoid damage caused by prolonged exposure of the seal to the outside world.

[0024] Preferably, the outer side of the chapter tube has an outer slide groove, and the chapter tube movable cover is matched with the outer slide groove; the inner side of the chapter tube has an inner slide groove, and the seal inner sleeve is matched with the inner slide groove.

[0025] The outer slide groove on the outside of the seal tube is a vertical guide channel used to guide the up and down movement of the seal tube movable cover. The inner slide groove is provided on the inner side of the seal tube for assembly with the seal inner sleeve. The design of the inner slide groove makes the seal inner sleeve move more smoothly inside the seal tube, and prevents the seal inner sleeve from rotating or tilting during the stamping process, thereby ensuring the correct alignment of the seal pattern and the clarity of the imprint. The design of the outer and inner slide grooves improves the stability and precise control ability of the seal mechanism.

[0026] Preferably, an inner convex block is provided on the inner side of the movable cover of the chapter tube, and the movable cover of the chapter tube is matched with the outer slide groove through the inner convex block, so that the movable cover of the chapter tube moves up and down relative to the chapter tube; the inner sleeve of the seal has an outer convex strip, and the inner sleeve of the seal is matched with the inner slide groove through the outer convex strip, so that the inner sleeve of the seal moves up and down relative to the chapter tube.

[0027] The inner convex block on the movable cover of the seal tube is matched with the outer slide groove on the outer side of the seal tube, and the outer convex strip on the inner sleeve of the seal is matched with the inner slide groove on the inner side of the seal tube, so that the seal moves up and down in the seal tube more stably. This kind of cooperation not only reduces friction, but also effectively avoids deflection or rotation during movement. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The inner positioning piece 2 is used to simulate the real effect after the seal is dropped. The outer positioning frame 1 is provided with the fitting and disengagement hole 3, and the fitting and disengagement hole 3 forms the disengagement cavity 4 between the inner positioning piece 2 and the outer positioning frame 1. The disengagement cavity 4 allows the hand to be more naturally extended between the inner positioning piece 2 and the outer positioning frame 1 during operation, so as to facilitate the placement or removal of the inner positioning piece 2.

[0040] It should be noted that the inner positioning piece 2 has an arc-shaped edge at one end and a straight edge at the other end. The purpose of the design is to provide the user with a more obvious direction indication, so as to facilitate the distinction of the front and back directions of the inner positioning piece, avoid directional errors when placing the seal, and ensure that the pattern of the seal is correctly aligned with the target position.

[0041] like Figure 3 , Figure 4 As shown, the transparent middle layer 5 between the upper surface and the lower surface of the inner positioning piece 2 makes it easy for the user to see the precise alignment position of the seal and the document to be stamped through the inner positioning piece 2. The outer positioning frame 1 is provided with the inner peripheral edge 6 and the outer peripheral edge 7. The inner peripheral edge 6 is movably assembled with the inner positioning piece 2 to reduce the sliding of the inner positioning piece 2 in the outer positioning frame 1 during the pre-positioning process to enhance the positioning accuracy. The inner positioning piece 2 is not fixed on the inner peripheral edge 6 and can be taken out or inserted through the detachment cavity 4 when in use.

[0042] It should be noted that the area between the outer edge 7 and the inner edge 6 on the outer positioning frame should be at least larger than 5 cm 2 The thickness of the outer edge 7 and the inner edge 6 need to be consistent, and the thickness of the inner edge 6 is the same as the thickness of the transparent intermediate layer 5 on the inner positioning sheet 2 to ensure the balance and consistency of the inner positioning sheet 2 inside the outer positioning frame 1, avoiding tilt or uneven pressure during the stamping process, thereby affecting the stamping effect.

[0043] The inner positioning piece 2 and the outer positioning frame 1 need to be used together with the seal mechanism when they cooperate in positioning.
