[0014] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a semi-automatic stamping machine suitable for calligraphy works.

[0015] like Figures 1-5As shown, this utility model discloses a semi-automatic stamping machine suitable for calligraphy works, including a base plate 1 with a hollow square hole 101 in the middle. A fixed support 2 is installed on the base plate 1, and a connecting rod 3 is slidably connected to the fixed support 2. A light source bracket 4 is fixedly connected to the end of the connecting rod 3, and a stamp clamping frame 6 is fixedly connected to the bottom of the connecting rod 3 through a connecting frame 5. The stamp clamping frame 6 is coaxially arranged with the light source bracket 4, with its center line vertically aligned and located above the hollow square hole 101. A parallel light projection light source 7 is provided inside the light source bracket 4. A stamp 8 is clamped on the stamp clamping frame 6, and clamping plates are symmetrically arranged on the stamp 8. A clamping adjustment knob passes through the lugs I 61 and II 62 on the stamp clamping frame 6 and is connected to the clamping plate to adjust the clamping force of the clamping plate on the stamp 8 and to fix the stamp clamping frame 6.

[0016] In this embodiment, the base plate 1 has four threaded holes for connecting the fixed support 2. The fixed support 2 serves to connect the base plate 1 and other mechanisms and needs to have sufficient strength to maintain the stability of the overall mechanism when stamping. The bottom of the fixed support 2 has four circular through holes, and four screws are used to pass through the four circular through holes and fix them to the four threaded holes on the base plate 1. The stamp 8 is symmetrically provided with clamping plates, namely clamping plate one 9 and clamping plate two 10, which are clamped by clamping adjustment knob one 11 and clamping adjustment knob two 12 respectively. The parallel light projection source 7 is inserted into the upper part of the circular cutout of the light source bracket 4. The circular skirt serves as a limit for the upper and lower parts. Four screws are used to connect and fix the light source bracket 4 to the four threaded holes around the circular cutout of the light source through the four through holes of the circular skirt.

[0017] The end of the connecting frame 5 is a hollow circular fixing frame 501, and the fixing frame 501 is fixedly connected to the seal holder 6 by fixing screw one 17 and fixing screw two 18. When stamping, the base plate 1 is placed on the calligraphy work to flatten and fix the work, preventing it from moving during stamping. The center of the base plate 1 has a hollow square hole 101 for observing the stamping position. The clamping adjustment knob 11 and clamping adjustment knob 212 pass through the lugs I 61 and II 62 on the seal clamping frame 6 and act on the clamping plates 1 9 and 2 10. The clamping plates 1 9 and 2 10 act on the seal 8. By tightening the clamping adjustment knobs 11 and 2 12, the seal 8 is fixed and the seal clamping frame 6 is also fixed. The parallel light projection light source 7 is turned on to find the position on the work to be stamped. When the position is uncertain, the tightening force of the clamping adjustment knobs 11 and 2 12 is adjusted to adjust the angle of the seal 8 and press it on the connecting rod 3, thereby realizing the stamping of the calligraphy.

[0018] A guide rail 13 is installed on the fixed support 2. Six threaded holes are opened on the side of the fixed support 2 for connecting the guide rail 13. A slider 14 that can move up and down is installed on the guide rail 13. A connecting rod 3 is fixed on the slider 14. The guide rail 13 has a dovetail structure and six circular grooves. Six screws are used to fasten the guide rail 13 to the fixed support 2 through the six circular grooves. After the six screws are tightened, the height does not exceed the sliding plane of the guide rail 13. The slider 14 and the guide rail 13 form a motion unit. A ball bearing is installed inside the slider 14. The two achieve relative up and down movement through rolling friction. The slider 14 has four threaded holes for connecting with the connecting rod 3.

[0019] The clamping adjustment knob 11 and clamping adjustment knob 2 are threaded rods. The support ears 161 and 262 of the stamp clamping frame 6 are provided with threaded holes. The threaded rods cooperate with the threaded holes on the support ears 161 and 262. The end of the threaded rods is a spherical structure. The clamping plate 19 and clamping plate 20 are provided with a semi-concave spherical structure.

[0020] In this embodiment, the seal holder 6 and the seal 8 are fixed by the threaded connection between the threaded rods of the clamping adjustment knob 11 and the clamping adjustment knob 2 and the threaded holes on the lugs 161 and 262 of the seal holder 6, ensuring the stability of the seal 8. The clamping plate 19 is connected to the clamping adjustment knob 11 in a spherical anti-disengagement form. The threaded end of the clamping adjustment knob 11 is spherical, and the corresponding position of the clamping plate 19 is a semi-concave sphere. During assembly, a certain force is required to press the sphere of the clamping adjustment knob 11 into the semi-concave sphere of the clamping plate 19. This ensures that the clamping plate 19 does not rotate when the clamping adjustment knob 11 rotates. The clamping adjustment knob 212 is connected to the clamping plate 210 in the same way as described above.

[0021] The clamping plate 9 and clamping plate 10 are inverted L-shaped structures, the purpose of which is to prevent the stamp 8 from sliding upwards during the stamping operation by using the short upper side.

[0022] A gas spring 15 is fixedly connected to the bottom of the slider 14, and the other end of the gas spring 15 is fixed to the base plate 1 by a square connecting block 16.

[0023] In this embodiment, a square connecting block 16 is designed on the base plate 1. A threaded hole is opened on the square connecting block 16 for fixed connection with the gas spring 15. A threaded hole is opened at the bottom of the slider 14 for fixed connection with one end of the gas spring 15. The gas spring 15 provides support. The lower part is fixedly connected to the threaded hole of the square connecting block 16 on the base plate 1 with a screw, and the upper part is fixedly connected to the threaded hole of the slider 14 with a screw. The gas spring 15 bears the weight of the connecting rod 3, the light source bracket 4, the parallel light projection light source 7, the seal holder 6 and the seal 8, keeping the bottom of the seal 8 at a certain distance from the upper part of the base plate 1, so as not to affect the aiming of the stamping position through the hollow square hole 101. When subjected to downward pressing stamping action, it can be compressed to ensure that the bottom of the seal can contact the calligraphy work.

[0024] The working principle of a semi-automatic stamping machine suitable for calligraphy works is as follows: First, the stamp 8 dipped in ink is fixed in the stamp holder 6. Then, the stamp holder 6 is fixed to the fixing frame 501 of the connecting frame 5. The semi-automatic stamping machine is placed on the calligraphy work, and the parallel light projection light source 7 is turned on. The position of the base plate 1 is adjusted by observing the shadow of the stamp 8 through the hollow square hole 101 of the base plate 1. After the position is determined, if it is necessary to fine-tune the rotation angle of the stamp 8, the connecting fixing screw 17 and fixing screw 18 of the stamp holder 6 and the connecting frame 5 can be loosened to rotate the stamp holder 6. After the angle is determined, the fixing screw 17 and fixing screw 18 are tightened again. The connecting rod 3 is pressed down to drive the slider 14 to compress the gas spring 15 to complete the stamping of the calligraphy work at the designated position. After the stamping is completed, the gas spring 15 returns to the initial position.
