Using computer-aided design software, engineers design the drawings of the parts, define the shape, size and tolerance of the parts, and select appropriate raw materials according to the usage requirements of the parts.
[0003] The next step is to prepare for processing, including the preparation of cutting, shaping, and processing tools, ensuring that all equipment and tools are in good condition.

[0004] Existing clamping devices clamp parts by moving the clamps in opposite directions. However, when clamping irregularly shaped parts, due to differences in shape and thickness, it is necessary to change to a suitable clamping device, which reduces the flexibility of the clamping device and makes it difficult to properly fix parts of different specifications. Therefore, a high-precision clamping device for production and processing is proposed to solve the above problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a high-precision clamping device for manufacturing and processing, including a worktable 1. A vertical plate 3 is fixedly connected to the top wall of the worktable 1. Electric telescopic rods 4 are fixedly connected to the left and right sides of the bottom of the vertical plate 3. A displacement plate 5 is fixedly connected to the rear end of the electric telescopic rods 4. The front left and right sides of the displacement plate 5 are provided with through grooves 6. By activating the electric telescopic rods 4, the rear end of the electric telescopic rods 4 can drive the displacement plate 5 to move, thereby achieving initial clamping and fixing of the parts. A horizontal groove 7 is provided in the middle of the front side of the displacement plate 5. The through grooves 6 and the horizontal groove 7 allow the limiting shell 8 and the sliding shell 13 to pass through the displacement plate 5, avoiding the displacement plate 5 from colliding with the limiting shell 8 and the sliding shell 13 and affecting clamping. The rear left and right sides of the vertical plate 3 are provided with through grooves 6 and 7. The end is fixedly connected to the limiting shell 8. The front middle of the displacement plate 5 is provided with a sliding groove 14. The inner wall of the displacement plate 5 is provided with a sliding shell 13. The bottom of the sliding shell 13 is slidably connected to the sliding groove 14. By sliding the sliding shell 13, it is easy to adapt to different parts of the irregular part. The inner walls of the limiting shell 8 and the sliding shell 13 are rotatably connected with threaded rods 9. The outer wall of the threaded rod 9 is threadedly connected with a clamping plate 10. The front end of the threaded rod 9 is fixedly connected with a knob 11. By rotating the knob 11, the threaded rod 9 drives the clamping plate 10 to move, so as to fix the irregular part. The rear side of the worktable 1 is provided with a collection mechanism 2. The collection mechanism 2 is used to collect the debris generated during the processing of the parts.
[0033] Specifically, the part to be processed is placed between the displacement plate 5 and the upright plate 3. By activating the electric telescopic rod 4, its rear end drives the displacement plate 5 forward, thereby achieving initial positioning and fixation of the part. According to the specific shape of the part, the horizontal position of the sliding shell 13 can be adjusted so that the bottom clamping plate 10 can select a suitable clamping position according to the width of the part. By rotating the knob 11, the threaded rod 9 is rotated. At the same time, under the rotation restriction inside the limiting shell 8 and the sliding shell 13, it is ensured that the multiple clamping plates 10 will not rotate, but will move along the direction of the threaded rod 9. This can better achieve precise fixation of the part, reduce the risk of processing failure due to unstable clamping during processing, and avoid the trouble of changing different clamping devices when processing irregular parts, thereby improving the flexibility and adaptability of the device and making the entire processing process more efficient and stable.
[0034] Reference Figure 1 , Figure 2 and Figure 4 The extraction mechanism 2 includes an extraction fan 201. An extraction pipe 202 is connected to the left side of the extraction fan 201, and a collection box 204 is connected to the front end of the extraction pipe 202. Activation of the extraction fan 201 allows the extraction pipe 202 and collection box 204 to collect processing debris. Two inclined grooves 203 are formed on the inner bottom wall of the workbench 1. The top wall of the collection box 204 is connected to the bottom wall of the workbench 1. A filter plate 205 is fixedly installed on the inner wall of the collection box 204. The inclined grooves 203 allow for effective filtration of the debris. The debris is guided into the collection box 204 and blocked by the filter plate 205 to prevent it from entering the extraction fan 201 and causing damage. The bottom wall of the vertical plate 3 is fixedly connected to the extraction head 206. The left and right ends of the rear side of the extraction head 206 are connected to the connecting pipe 207. The bottom end of the connecting pipe 207 penetrates the interior of the workbench 1 and connects to the top wall of the collection box 204. The extraction head 206 can expand the range of debris extraction and can also cool the processed parts.
[0035] Specifically, by activating the extraction fan 201, the inclined chute 203 generates an extraction airflow, while the extraction head 206 simultaneously extracts air. Debris generated during part processing can be extracted through the inclined chute 203 and the extraction head 206. The debris follows the path of the inclined chute 203 and the connecting pipe 207, eventually entering the collection box 204. The filter plate 205 prevents debris from entering the extraction fan 201, thus avoiding potential damage to the impeller inside the fan. After the debris extraction is complete, the extraction head 206 can also cool the processed parts. By allowing airflow to pass over the surface of the parts for heat exchange, the temperature of the parts is effectively reduced, thereby improving the processing efficiency and overall production efficiency.
[0036] Reference Figure 2 , Figure 4 and Figure 5 The extraction mechanism 2 also includes a rubber ring 208, the inner wall of which is fixedly installed on the outer wall of the extraction tube 202, and the outer wall of which is fixedly connected to the rear side of the collection box 204; a control switch 17 is fixedly connected to the front side of the workbench 1, and the control switch 17 is electrically connected to the electric telescopic rod 4 and the extraction fan 201 respectively; rubber blocks 16 are fixedly connected to the rear side of multiple clamping plates 10, and a rubber pad 15 is fixedly connected to the top of the front side of the displacement plate 5;
[0037] Specifically, the rubber ring 208 protects the connection of the outer wall of the extraction tube 202, thereby reducing wear at the connection point of the extraction tube 202. The control switch 17, which is electrically connected to the electric telescopic rod 4 and the extraction fan 201 respectively, can turn the device on and off. The rubber pad 15 and the rubber block 16 improve the device's ability to fix the parts.
[0038] Reference Figure 1 and Figure 2 A baffle plate 20 is fixedly connected to the bottom front side of the displacement plate 5. The front side of the baffle plate 20 has a smooth design. Two support plates 18 are fixedly connected to the left and right sides of the collection box 204. The top walls of the multiple support plates 18 are provided with mounting grooves 19. Multiple rubber strips 12 are fixedly connected to the outer walls of the multiple knobs 11. The multiple rubber strips 12 are arranged in a ring at equal intervals.
[0039] Specifically, the position of the displacement plate 5 can be limited by the barrier plate 20 to prevent excessive displacement, the support plate 18 and the mounting groove 19 facilitate the fixing and installation of the device, and the rubber strip 12 facilitates the use of the knob 11 and improves the anti-slip effect.
[0040] Working principle: When starting to use, place the part between the displacement plate 5 and the upright plate 3. By activating the rear end of the electric telescopic rod 4, it drives the displacement plate 5 to move forward, so that the part to be processed can be initially positioned and fixed. Then, adjust the horizontal position of the sliding shell 13 according to the shape of the part, so that the bottom clamping plate 10 can select a suitable clamping position according to the width of the part. By turning the knob 11, the threaded rod 9 is rotated. At the same time, under the rotation restriction inside the limiting shell 8 and the sliding shell 13, the multiple clamping plates 10 will not rotate, and then move along the direction of the threaded rod 9, so as to better complete the precise fixation of the part, reduce the situation of processing failure due to unstable clamping, avoid the need to change different clamping devices to fix irregular parts, and improve the flexibility and adaptability of the device.
[0041] Furthermore, by activating the extraction fan 201, the inclined chute 203 can generate an extraction airflow, while the extraction head 206 simultaneously extracts air. Thus, the debris generated during the processing of the parts can be extracted through the inclined chute 203 and the extraction head 206, allowing the debris to enter the collection box 204 through the inclined chute 203 and the connecting pipe 207 respectively. With the filter plate 205 blocking the debris, it will not enter the interior of the extraction fan 201 and cause damage to its internal impeller. After the debris extraction is completed, the extraction head 206 can cool the processed parts, allowing the airflow to pass over the surface of the parts for heat exchange, thereby improving the processing efficiency of the parts.
[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
