[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] This utility model provides a positioning guide plate for 3D printing. By pushing a pusher plate towards the center of the positioning base, a clamping plate is slid towards the center of the positioning base via a limiting rack. This causes spring deformation. The pushing distance is determined by the scale on a first ruler. After one clamping plate is pushed to the appropriate position, the model can be placed between the two clamping plates.

During this process, the model's position can be precisely adjusted using the first ruler, flexibly adjusting the model's positioning and improving the accuracy of model positioning. This ensures the model maintains the correct position and posture during printing, allowing for precise guidance of the print head or nozzle according to the design requirements, reducing printing deviations or... In the event of deformation, and when releasing the clamping restriction on the model, simply rotating the two rotating shafts will cause the corresponding limiting claws to leave the corresponding limiting racks.

This reduces the likelihood of printing offsets or deformations, and when releasing the clamping restriction on the model, simply rotating the two rotating shafts will cause the corresponding limiting claws to leave the corresponding limiting racks.

Detailed Implementation

[0027] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0028] As described in the background art, in actual 3D printing, it is often necessary to adjust the placement of the model according to the shape and size of the printed model in order to make better use of the printing space. However, the above-mentioned device can only attach the model to the fixed block A and then rely on the fixed block B to clamp the model, which makes it impossible to adjust the fixed position of the model, and its practicality is relatively low.

[0029] To solve this technical problem, this utility model provides a positioning guide plate for 3D printing, which is used for model positioning in 3D printing.

[0030] For details, please refer to Figures 1-2The positioning guide plate used for 3D printing specifically includes:

[0031] Positioning base 1, with positioning mechanisms 2 on the left and right sides of positioning base 1 respectively, and an auxiliary mechanism 3 on one of the positioning mechanisms 2;

[0032] The positioning mechanism 2 includes a clamping plate 4, a limiting rack 5, a pushing component, and a limiting component. The clamping plate 4 is slidably connected to the top of the positioning base 1. The limiting rack 5 is fixedly connected to the outer wall of the clamping plate 4 and slidably connected to the inner wall of the positioning base 1.

[0033] The positioning guide plate for 3D printing provided by this utility model pushes the push plate 6 towards the center of the positioning base 1. This causes the clamping plate 4 to slide towards the center of the positioning base 1 via the limiting rack 5, resulting in the deformation of the spring 7. The pushing distance is determined by the scale on the first scale 11. After pushing one clamping plate 4 to the appropriate position, the model can be placed between the two clamping plates 4. Then, pushing the other push plate 6 causes the two clamping plates 4 to clamp the model. During this process, the position of the model can be precisely adjusted using the first scale 11, allowing for flexible adjustment of the model's positioning and improving the device's ability to precisely control the model. The accurate positioning ensures that the model maintains the correct position and posture during printing, enabling precise guidance of the print head or nozzle to print according to the design requirements, reducing printing offsets or deformations. Furthermore, when releasing the model from the clamping constraints, simply rotating the two rotating shafts 8 will cause the corresponding limiting claws 9 to disengage from the corresponding limiting racks 5. Subsequently, under the elastic force of the two springs 7, the two clamping plates 4 will move away from each other, thus releasing the model from the clamping constraints. This process is relatively simple and facilitates the operator in removing the printed model, improving the practicality of the device.

[0034] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0035] Example 1:

[0036] Please refer to Figures 2-3 A positioning guide for 3D printing, comprising:

[0037] The pushing component includes a push plate 6. The end of the limiting rack 5 away from the clamping plate 4 is fixedly connected to the push plate 6. A spring 7 is sleeved on the outside of the limiting rack 5. The two ends of the spring 7 are fixedly connected to the outer wall of the push plate 6 and the positioning base 1, respectively. A first scale 11 is fixedly connected to the top of the limiting rack 5. The first scale 11 can measure the distance from the side of the clamping plate 4 away from the positioning base 1 to the positioning base 1, thereby assisting the operator in positioning the model.

[0038] The limiting component includes a rotating shaft 8, which is rotatably connected to the inner wall of the positioning base 1. A limiting claw 9 adapted to the limiting rack 5 is fixedly connected to the outer wall of the rotating shaft 8. A torsion spring 10 is sleeved on the outside of the rotating shaft 8. The two ends of the torsion spring 10 are fixedly connected to the outer wall of the limiting claw 9 and the inner wall of the positioning base 1, respectively. The limiting claw 9 does not restrict the clamping plate 4 from moving toward the center of the positioning base 1, but the limiting claw 9 cooperates with the limiting rack 5 to restrict the clamping plate 4 from sliding away from the center of the positioning base 1, so as to ensure the stability of the model clamping.

[0039] With the above structural design, during use, by pushing the push plate 6 towards the center of the positioning base 1, the clamping plate 4 will slide towards the center of the positioning base 1 via the limiting rack 5. The spring 7 will then deform. The pushing distance is determined by the scale on the first scale 11. After pushing one clamping plate 4 to the appropriate position, the model can be placed between the two clamping plates 4. Then, push the other push plate 6 so that the two clamping plates 4 cooperate to clamp the model. During this process, the position of the model can be precisely adjusted by the first scale 11. When releasing the clamping restriction on the model, simply rotate the two rotating shafts 8 to drive the corresponding limiting claws 9 away from the corresponding limiting rack 5. Then, under the action of the elastic force of the two springs 7, the two clamping plates 4 will move away from each other, thus releasing the clamping restriction on the model.

[0040] Example 2:

[0041] The positioning guide plate for 3D printing provided in Example 1 is further optimized, specifically, as follows: Figures 4-5 As shown, the auxiliary mechanism 3 includes a sliding block 12, a T-shaped strip 13, an adjustment component, and a receiving component. The sliding block 12 is slidably connected to the inner wall of the clamping plate 4. The upper and lower sides of the sliding block 12 are respectively fixedly connected to the T-shaped strip 13. Both T-shaped strips 13 are slidably connected to the inner wall of the clamping plate 4. The sliding block 12 serves to connect the indicator block 15 and the L-shaped plate 17.

[0042] The adjustment assembly includes a threaded rod 14, which is rotatably connected to the inner wall of the clamping plate 4. The threaded rod 14 is threadedly connected to the inner wall of the sliding block 12. An indicator block 15 is fixedly connected to the outer wall of the sliding block 12. The indicator block 15 is slidably connected to the inner wall of the clamping plate 4. A second scale 16 is fixedly connected to the top of the clamping plate 4. The cooperation between the indicator block 15 and the second scale 16 can reflect the current position of the sliding block 12 within the clamping plate 4, so that the operator can confirm the position of the L-shaped plate 17 based on the position of the sliding block 12.

[0043] The receiving component includes an L-shaped plate 17. The outer wall of the sliding block 12 is fixedly connected to the L-shaped plate 17. The L-shaped plate 17 is slidably connected to the inner wall of the clamping plate 4. The outer wall of the L-shaped plate 17 is fixedly connected to a friction pad 18. The top and middle of the friction pad 18 are provided with a guide groove 19. The friction pad 18 is made of silicone with good temperature resistance and chemical resistance. When the model is placed on the friction pad 18, the guide groove 19 can be used as a reference to adjust the position of the model to ensure the accuracy of the model positioning. The bottom of the clamping plate 4 is provided with a through groove that matches the height of the friction pad 18 and the guide groove 19, so that the friction pad 18 and the guide groove 19 can be inserted when the bottom area of ​​the model is small.

[0044] With the above structural design, rotating the threaded rod 14 can drive the sliding block 12 and the T-shaped strip 13 to move under the restriction of the clamping plate 4, which in turn drives the indicator block 15 and the L-shaped plate 17 to move. The position where the sliding block 12 should stop can be determined according to the second scale 16 indicated by the indicator block 15. Then, the model can be placed on the friction pad 18 on the L-shaped plate 17, and the middle part of the model can be aligned with the guide groove 19. Then, the model can be clamped and positioned by the proximity of the two clamping plates 4.
