Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, and in particular to a clamping and positioning device for wood processing. Background Technology

[0002] In the processing of some wooden furniture, clamping and positioning devices are needed on lathes to position the wooden blocks before machining them into furniture. This prevents the wood from shifting during processing, thus ensuring processing accuracy and the quality of the finished furniture. However, traditional clamping and positioning devices have poor stability, and the wood is prone to loosening after clamping, leading to processing errors, defective products, and wasted raw materials. In addition, traditional clamping and positioning devices are often only suitable for one type of wood and are difficult to adapt to different sizes of wood, resulting in poor practicality.

[0003] A patent with publication number CN211517779U discloses a clamping and positioning device for wood processing. This patent includes an operating lathe, a movable slide, a movable connecting rod, a fixed clamping block, an adjusting ring, a square locking block, a movable slot, and small protruding ribs. By providing four independent clamping and positioning devices, it can accommodate wood of different shapes. Furthermore, these four independent clamping and positioning devices can be adjusted independently, thus adapting to wood of different sizes. Large pieces of wood can be fixed simultaneously using all four clamping and positioning devices, while small pieces can be fixed using only two. The fixing method is quite flexible. The cooperation between the adjusting ring and the square locking block allows the clamping and positioning device to achieve positioning at any point, further improving its practicality. Adjustment and fixing of the four independent clamping and positioning devices is simply a matter of rotating the adjusting ring 5 clockwise to fix the fixed clamping block 4 and rotating it counterclockwise to loosen and disassemble the fixed clamping block 4. However, this patent still has the following problems:

[0004] The above-mentioned methods for positioning and clamping wood cannot adapt to curved wood of different shapes and sizes, have poor versatility, uneven clamping force, and are prone to displacement of wood during processing. They are also complicated to adjust, inconvenient to operate, and affect production efficiency.

[0005] To address the above problems, a clamping and positioning device for wood processing needs to be designed to overcome them. Utility Model Content
