Description

Technical Field

[0001] This utility model relates to the field of plastic prototype technology, and in particular to a rapid prototyping structure for plastic prototypes. Background Technology

[0002] A prototype is a physical sample used in the early stages of product development to verify feasibility. Technical terms include prototype, verification sample, and scale model. Its purpose is to detect defects in appearance, structure, or function through a small number of samples, avoiding the waste of resources by directly opening a mold. Commonly used materials include ABS, PC, and metal.

[0003] For example, CN214053657U discloses a laser rapid prototyping device for prototype processing, including a hollow plate, a strip box, and a box body. A rectangular groove is provided on the bottom side of one side of the box body, and an operation panel is installed inside the rectangular groove. The hollow plate is installed on the bottom side of the box body on the side where the operation panel is installed, and a square groove is provided at the center of the side of the hollow plate. Both ends of the square groove are slidably connected to baffles, and there are two baffles symmetrically arranged. A rectangular slot is provided on one symmetrical side of the square groove, and the two baffles at their far ends pass through the two rectangular slots and are slidably connected inside the hollow plate. A synchronous moving mechanism for synchronously moving the two baffles is provided inside the hollow plate.

[0004] However, in existing technologies, the design of laser rapid prototyping devices focuses on solving two core needs: the difficulty in removing the prototype due to its excessive weight and the susceptibility of the control panel to impact damage. This neglects the supporting requirements for the stable placement of raw materials, such as block plastic materials, before or during processing. The structure for placing raw materials is not included in the overall design of the device, which leads to the easy displacement and tipping of raw materials when placed around the device or in processing-related areas. This not only makes it inconvenient to retrieve raw materials and reduces the overall efficiency of prototype processing, but also indirectly interferes with the continuity and stability of prototype forming. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution: It includes a processing box assembly, which consists of a box body and an operation panel. A box door is rotatably connected to the side of the box body. A base is fixedly connected inside the box body. A moving mechanism is fixedly connected to the upper part of the base. A limiting mechanism is fixedly connected to the upper part of the moving mechanism. The limiting mechanism includes a connecting frame. A mounting frame is fixedly connected to the upper part of the connecting frame. A second electric telescopic rod is fixedly connected to the bottom of the mounting frame. A vertical clamping plate is fixedly connected to the bottom of the second electric telescopic rod. A third electric telescopic rod is installed on the upper part of the vertical clamping plate. A side clamping plate is fixedly connected to the end of the third electric telescopic rod.

[0007] Preferably, the moving mechanism includes a fixed plate, which is fixedly connected to the upper part of the base, and a shaft-pull linear slide rail is installed on the side of the fixed plate, and a processing table is installed on the side of the shaft-pull linear slide rail.

[0008] Preferably, a first mounting plate is fixedly connected to the upper part of the base, a first electric telescopic rod is fixedly connected to the side of the first mounting plate, a second mounting plate is fixedly connected to the end of the first electric telescopic rod, and the second mounting plate is fixedly connected to the bottom of the processing table.

[0009] Preferably, a limiting rod is fixedly connected to the upper part of the vertical clamping plate, and the limiting rod is slidably inserted into the mounting bracket.

[0010] Preferably, a protective pad is fixedly connected to the lower part of the vertical clamping plate.

[0011] Preferably, the end of the side clamp is fixedly connected with a second protective pad.

[0012] Preferably, a limiting slide rail is fixedly connected to the upper part of the vertical clamping plate, and the bottom of the side clamping plate is slidably connected to the limiting slide rail.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, in the limiting mechanism, the connecting frame provides fixed support for the mounting frame. The second electric telescopic rod at the bottom of the mounting frame can push the vertical clamping plate downward to firmly clamp the raw material between the base and the vertical clamping plate, thus achieving reliable vertical fixation of the raw material.

At the same time, the convenient push-out and retraction of the processing table also improves the ease of operation and adapts to the actual operation needs of plastic prototype processing. 2. In this utility model, the No. 1 protective pad, fixed below the end of the vertical clamping plate, can directly contact the upper surface of the raw material when the vertical clamping plate clamps the raw material vertically, avoiding scratches and pressure damage to the surface of the raw material caused by the rigid clamping of the vertical clamping plate, and effectively protecting the appearance and integrity of the raw material; the No. 2 protective pad, installed at the end of the side clamping plate, can buffer the direct impact of the lateral clamping force on the side of the raw material when the No. 3 electric telescopic rod pushes the side clamping plate to clamp the side of the raw material, preventing damage to the side of the raw material due to rigid contact, and ensuring the integrity of the raw material before processing; 3. In this utility model, the limiting rod, fixed to the upper part of the vertical clamping plate and slidably connected to the mounting frame, can slide stably along the mounting frame during the up-and-down movement of the vertical clamping plate driven by the second electric telescopic rod, accurately limiting the movement trajectory of the vertical clamping plate, avoiding deviation and shaking during the movement of the vertical clamping plate, and significantly improving the stability of the vertical movement of the vertical clamping plate and the accuracy of the clamping position; the limiting slide rail, fixed to the upper part of the vertical clamping plate and slidably connected to the bottom of the side clamping plate, can provide stable sliding guidance for the side clamping plate when the third electric telescopic rod pushes the side clamping plate to move horizontally, limiting the horizontal movement trajectory of the side clamping plate, and preventing the side clamping plate from deviating and causing inaccurate clamping of the raw material side.

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1: As Figure 1 - Figure 5 As shown, this utility model provides a rapid prototyping structure for plastic prototypes, including a processing box assembly 1. The processing box assembly 1 consists of a box body 11 and an operation panel 12. A box door 13 is rotatably connected to the side of the box body 11. A base 14 is fixedly connected inside the box body 11. A moving mechanism 2 is fixedly connected to the upper part of the base 14. A limiting mechanism 3 is fixedly connected to the upper part of the moving mechanism 2. The limiting mechanism 3 includes a connecting frame 31. A mounting frame 32 is fixedly connected to the upper part of the connecting frame 31. A second electric telescopic rod 33 is fixedly connected to the bottom of the mounting frame 32. A vertical clamping plate 34 is fixedly connected to the bottom of the second electric telescopic rod 33. A third electric telescopic rod 36 is installed on the upper part of the clamping plate 34. A side clamping plate 38 is fixedly connected to the end of the third electric telescopic rod 36. The moving mechanism 2 includes a fixed plate 21, which is fixedly connected to the upper part of the base 14. A shaft-pull linear slide rail 22 is installed on the side of the fixed plate 21. A processing table 26 is installed on the side of the shaft-pull linear slide rail 22. A first mounting plate 23 is fixedly connected to the upper part of the base 14. A first electric telescopic rod 24 is fixedly connected to the side of the first mounting plate 23. A second mounting plate 25 is fixedly connected to the end of the first electric telescopic rod 24. The second mounting plate 25 is fixedly connected to the bottom of the processing table 26.

[0019] The specific settings and functions of this embodiment are described below: The No. 1 electric telescopic rod 24 pushes the No. 2 mounting plate 25 to push the processing table 26 out of the box 11, and the plastic prototype raw material to be processed is placed on the surface of the processing table 26. At this time, the shaft-pull linear slide rail 22 unfolds step by step to provide stable support for both sides of the processing table 26. Then, the No. 2 electric telescopic rod 33 pushes the vertical clamping plate 34 to move downward, and the raw material is clamped between the base 14 and the vertical clamping plate 34. For raw materials with protrusions on both sides, the No. 3 electric telescopic rod 36 pushes the side clamping plate 38 to clamp and fix the sides of the raw material again to ensure that the raw material is placed stably. The housing 11 of the processing box assembly 1 provides the installation foundation for the overall structure, the door 13 ensures the sealing of the processing environment, and the base 14 provides stable support for the moving mechanism 2 and the placement of raw materials. In the moving mechanism 2, the first electric telescopic rod 24 can push the second mounting plate 25 to push the processing table 26 out of the housing 11, making it convenient for workers to place plastic handpiece raw materials. At the same time, the axial pull linear slide rail 22 unfolds step by step as the processing table 26 moves, which can form stable support on both sides of the processing table 26 and prevent the processing table 26 from shaking when moving or carrying raw materials, providing a stable carrier for the initial placement of raw materials. In the limiting mechanism 3, the connecting frame 31 provides fixed support for the mounting frame 32, and the second electric telescopic rod 33 at the bottom of the mounting frame 32 can push the vertical clamping plate 34 to The downward movement securely clamps the raw material between the base 14 and the vertical clamping plate 34, achieving reliable vertical fixation of the raw material. For special raw materials with protrusions on both sides, the No. 3 electric telescopic rod 36 installed on the upper part of the vertical clamping plate 34 can push the side clamping plate 38 to perform secondary clamping on the side of the raw material, further supplementing lateral fixation and completely preventing the raw material from shifting or tipping before or during processing. The overall structure not only solves the problem of inconvenient raw material handling and improves the overall efficiency of prototype processing, but also ensures the stability of the plastic prototype raw material placement through multi-directional stable fixation, indirectly ensuring the continuity and stability of prototype forming. At the same time, the convenient extension and retraction of the processing table 26 also improves the ease of operation and adapts to the actual operational needs of plastic prototype processing.

[0020] Example 2: Figure 1 - Figure 5 As shown, a limiting rod 35 is fixedly connected to the upper part of the vertical clamping plate 34. The limiting rod 35 is slidably inserted into the mounting bracket 32. A first protective pad 39 is fixedly connected to the lower part of the end of the vertical clamping plate 34. A second protective pad 310 is fixedly connected to the end of the side clamping plate 38. A limiting slide rail 37 is fixedly connected to the upper part of the vertical clamping plate 34. The bottom of the side clamping plate 38 is slidably connected to the limiting slide rail 37.

[0021] The overall effect of this embodiment is that the upper surface of the raw material is protected by the first protective pad 39, and the side of the raw material is protected by the second protective pad 310; during the process of the second electric telescopic rod 33 driving the vertical clamping plate 34 to move up and down, the limiting rod 35 slides along the mounting frame 32 to limit the movement of the vertical clamping plate 34 and improve the stability of the vertical movement of the vertical clamping plate 34; the horizontal movement of the side clamping plate 38 is limited by the limiting slide rail 37 to improve the stability of the horizontal movement of the side clamping plate 38. The first protective pad 39, fixed below the end of the vertical clamping plate 34, can directly contact the upper surface of the raw material when the vertical clamping plate 34 clamps the raw material vertically, avoiding scratches and pressure damage to the surface of the raw material caused by the rigid clamping of the vertical clamping plate 34, and effectively protecting the appearance and integrity of the raw material; the second protective pad 310, installed at the end of the side clamping plate 38, can buffer the direct impact of the lateral clamping force on the side of the raw material (especially raw materials with protrusions) when the third electric telescopic rod 36 pushes the side clamping plate 38 to clamp it, preventing damage to the side of the raw material due to rigid contact, and ensuring the integrity of the raw material before processing; the limiting rod 35, fixed on the upper part of the vertical clamping plate 34 and slidably inserted into the mounting frame 32, can move along the mounting frame 32 during the up and down movement of the vertical clamping plate 34 driven by the second electric telescopic rod 33. Stable sliding precisely limits the movement trajectory of the vertical clamping plate 34, preventing deviation and wobbling during its movement, significantly improving the stability of the vertical movement of the vertical clamping plate 34 and the accuracy of its clamping position. The limiting slide rail 37, fixed to the upper part of the vertical clamping plate 34 and slidably connected to the bottom of the side clamping plate 38, provides stable sliding guidance for the side clamping plate 38 when the third electric telescopic rod 36 pushes it to move horizontally, limiting the horizontal movement trajectory of the side clamping plate 38 and preventing it from deviating and causing inaccurate clamping of the material side, further improving the stability of the horizontal movement of the side clamping plate 38 and the reliability of its clamping. This ensures that the material is both stable and intact during multi-directional clamping and fixing, providing a strong guarantee for the smooth processing of subsequent plastic prototypes and the quality of molding.

[0022] The usage method and working principle of this device are as follows: The No. 1 electric telescopic rod 24 pushes the No. 2 mounting plate 25 to push the processing table 26 out from the inside of the box 11. The plastic prototype material to be processed is placed on the surface of the processing table 26. At this time, the shaft-pull linear slide rail 22 unfolds step by step to provide stable support for both sides of the processing table 26. Then, the No. 2 electric telescopic rod 33 pushes the vertical clamping plate 34 to move downward. The vertical clamping plate 34 clamps the material between the base 14 and the vertical clamping plate 34. For materials with protrusions on both sides, the No. 3 electric telescopic rod 36 pushes the side clamping plate 38 to clamp and fix the sides of the material again to ensure that the material is placed stably. The first protective pad 39 protects the upper surface of the raw material, and the second protective pad 310 protects the side of the raw material. During the process of the second electric telescopic rod 33 driving the vertical clamping plate 34 to move up and down, the limiting rod 35 slides along the mounting frame 32 to limit the movement of the vertical clamping plate 34 and improve the stability of the vertical movement of the vertical clamping plate 34. The limiting slide rail 37 limits the horizontal movement of the side clamping plate 38 and improves the stability of the horizontal movement of the side clamping plate 38. After the raw materials are fixed, the moving mechanism 2 moves the limiting mechanism 3 and the fixed raw materials into the box 11 for the processing operation of the prototype.

[0023] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
