Description

Technical Field

[0002] In many sectors of manufacturing, such as furniture production, automobile manufacturing, electronic equipment assembly, and building decoration, the processing of sheet materials is a crucial step. In furniture production, wood panels need to undergo processes such as cutting, drilling, and sanding before they can be assembled into exquisite tables and chairs. These processing steps are complex and diverse, and reliable clamping mechanisms are indispensable to ensure processing accuracy, efficiency, and operator safety.

[0003] Existing processing and clamping mechanisms for sheet materials typically use small woodworking clamps to fix the sheet material to the top of the table or processing platform, changing the fixing angle by repeatedly tightening and loosening them.

[0004] On the one hand, existing small woodworking clamps require repeated manual adjustment of the fixed position, making it impossible to quickly clamp board materials of different sizes and maintain a certain clamping force. On the other hand, existing board material processing clamping mechanisms require repeated manual adjustment of the angle and fixed position to process board materials from multiple angles, making it impossible to quickly adjust the processing angle of board materials manually. Therefore, a processing clamping mechanism suitable for board materials is proposed to solve the above problems. Utility Model Content

[0032] The technical solutions of the present utility model 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 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.

[0033] Reference Figures 1-3 This utility model provides an embodiment of a clamping mechanism suitable for processing sheet materials, including a support base 1. The support base 1 provides support for a processing platform 2 and a processing instrument. The processing platform 2 is rotatably connected to the top of the outer wall of the support base 1. The processing platform 2 is used to place the sheet material and clamps it with clamping plates 5 through a limiting component for processing. A sliding groove 3 is provided on the top of the outer wall of the processing platform 2. Three sets of sliding grooves 3 are provided to keep the slider 4 moving stably along the sliding groove 3 and to avoid uneven force causing the clamping plate 5 to tilt. A slider 4 is slidably connected to the inner wall of the sliding groove 3. The slider 4 is used to engage with the sliding groove 3 to keep the clamping plate 5 moving stably. The middle set of slider 4 is extended and hinged to a connecting rod 6. The top of the outer wall of the slider 4 is fixedly connected to a clamping plate 5. Two sets of clamping plates 5 are provided to clamp the sheet material in opposite directions to keep it centered and fixed. A connecting frame 7 is connected to the bottom of the outer wall of the slider 4 through the connecting rod 6. The connecting frame 7 is used to hinge two sets of connecting rods 6, causing the two sets of connecting rods 6 to retract inward or expand outward simultaneously. The inner wall of the connecting frame 7 is rotatably connected to a threaded sleeve 8, which is used to drive the connecting frame 7 to move backward a second time, thereby causing the clamping plate 5 to clamp the plate material a second time. The inner wall of the threaded sleeve 8 is threadedly connected to a threaded rod 9, which is used to provide the connecting frame 7 with a distance for a second backward movement through the threaded sleeve 8. An auxiliary rod 10 is fixedly connected to the outer end of the threaded rod 9. The outer wall of the auxiliary rod 10 is provided with a directional block to keep the auxiliary rod 10 moving stably and to prevent the connecting rod 6 from bending due to twisting under force. The outer wall of the processing platform 2 is provided with a limit component. The bottom of the outer wall of the clamping plate 5 is slidably connected to the top of the outer wall of the processing platform 2. The bottom of the outer wall of the connecting rod 6 is hinged to the bottom of the outer wall of the slider 4. The top of the outer wall of the connecting rod 6 is hinged to the end of the outer wall of the connecting frame 7. The outer wall of the auxiliary rod 10 is slidably connected to the inner wall of the processing platform 2.

[0034] Reference Figures 2-4 A fixing rod 11 is elastically connected to the inner wall of the bottom end of the processing platform 2 via a return spring 12. A fixing block 13 is fixedly connected to the bottom of the outer wall of the fixing rod 11. The fixing block 13 is used to engage with the fixing groove 14 to keep the processing platform 2 stationary on the top of the support base 1. The top of the outer wall of the support base 1 is provided with a fixing groove 14. Several sets of fixing grooves 14 are provided to engage the fixing blocks 13 in multiple positions to change the rotation angle of the processing platform 2. One end of the return spring 12 is fixedly connected to the inner wall of the processing platform 2, and the other end of the return spring 12 is fixedly connected to the bottom end of the outer wall of the fixing rod 11. Through the opposing extrusion force between the return spring 12 and the inner wall of the processing platform 2, the fixing block 13 is always engaged with the inner wall of the fixing groove 14 without being affected by external force. The outer wall of the fixing rod 11 is slidably connected to the inner wall of the processing platform 2, and the outer wall of the fixing block 13 is engaged with the inner wall of the fixing groove 14.

[0035] Reference Figures 5-6The limiting assembly includes a limiting frame 15, which is used to maintain the stable up-and-down movement of the limiting block 17 and provides a fixing point for the limiting spring 16. The outer back of the limiting frame 15 is fixedly connected to the side wall of the processing platform 2. The inner wall of the limiting frame 15 is elastically connected to the limiting block 17 through the limiting spring 16. The limiting block 17 is used to engage with the limiting groove 19 to fix the movement distance of the auxiliary rod 10. The top of the outer wall of the limiting block 17 is fixedly connected to a limiting rod 18, which is used for external manual release of the limiting position for easy manual operation. The top of the outer wall of the auxiliary rod 10 has a limiting groove 19, which is provided in several sets for multiple engagement of the limiting block 17. 7. This changes the clamping distance of the clamping plate 5, achieving the effect of clamping plate materials of different sizes. One end of the limiting spring 16 is fixedly connected to the top of the inner wall of the limiting frame 15, and the other end of the limiting spring 16 is fixedly connected to the top of the outer wall of the limiting block 17. Through the opposing extrusion force between the limiting spring 16 and the top of the inner wall of the limiting frame 15, the limiting block 17 is always locked on the inner wall of the limiting groove 19 without being affected by external force. The outer wall of the limiting rod 18 passes through and is slidably connected to the inner wall of the limiting frame 15. The top of the outer wall of the limiting block 17 is slidably connected to the inner wall of the limiting frame 15, and the outer wall of the limiting block 17 is locked on the inner wall of the limiting groove 19.

[0036] Working principle: When clamping plate-shaped materials, the plate-shaped materials are placed on the top of the processing platform 2. The limiting rod 18 is pulled manually to move the limiting block 17 away from the limiting groove 19 to release the limit. Then, the threaded sleeve 8 is pulled backward manually to move the connecting frame 7 backward. The connecting frame 7 drives the two sets of connecting rods 6 to make a fan-shaped inward movement along the hinge of the connecting frame 7. Then, the connecting rod 6 drives the slider 4 to move towards the middle along the slide groove 3. Then, the slider 4 drives the clamping plate 5 to clamp the plate-shaped materials. Then, the limiting rod 18 is released and the limiting block 17 is rebounded into the corresponding limiting groove 19 by the limiting spring 16. Then, the threaded sleeve 8 is rotated manually to move the connecting frame 7 backward a second time, so as to clamp plate-shaped materials of different sizes and clamp them twice to provide processing stability.

[0037] When different angles are required to process sheet materials, the limiting position can be released by manually pulling the fixing rod 11 and reversing the fixing block 13 out of the fixing groove 14. Then, the fixing rod 11 can be manually moved laterally to rotate the processing platform 2 to the required angle. Then, the fixing rod 11 can be manually pushed inward to make the fixing block 13 engage with the corresponding fixing groove 14, thus realizing the manual change of the processing angle of the sheet material. This eliminates the need for repeated manual adjustment and greatly improves processing efficiency.

[0038] 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.
