Description

Technical Field

[0001] The utility model relates to the technical field of wood product processing, in particular to a circular arc surface drilling fixture for wood products. Background Art

[0002] At present, many circular wooden products need to be drilled on their curved surfaces. The drilling process usually needs to be completed with the help of a drilling machine, but the fixing of circular wooden products is extremely inconvenient. If it is not completed with the help of a special clamp, the product yield rate is low during processing. At the same time, the existing wooden product clamps are all rigidly clamped and fixed, and it is difficult to control the clamping force, which can easily cause damage or even damage to the surface of the wooden product, and the work efficiency needs to be further improved.

[0003] The prior art discloses a circular arc surface drilling fixture for wooden products with application number CN202122262798.5, which includes a base, a vertical plate, a rotating shaft, a gear, a fixed plate, a worm, a fixed shaft, a wooden product, a push plate, a movable groove, a spring, a movable block, a slider, a mounting groove, a screw, a threaded sleeve, a movable plate, a crank, a knob, a rubber sleeve and a slide groove. The wooden product is sleeved on the rubber sleeve and then the crank is shaken to rotate the screw. The rotation of the screw causes the threaded sleeve to move toward the wooden product, so that the inner side of the push plate slides on the rubber sleeve and the movable block slides in the movable groove. The push plate moves and pushes the spring for compression, and the push plate pushes one side of the wooden product while moving until the wooden product is firmly sleeved on the fixed shaft, thereby improving the application range of the clamp, facilitating the fixing of wooden products with different inner diameters, and no tools such as wrenches are required to tighten the nuts to clamp the wooden products, thereby improving work efficiency. However, when disassembling the wooden products, the friction resistance between the wooden products and the rubber sleeves is large, which increases the difficulty of disassembling the wooden products, and the rubber sleeves in the clamps are prone to wear after long-term use, which affects the firmness of the later fixation of the wooden products and reduces the service life of the clamp.
