TW200600302A - Trimming and splicing apparatus with adjustable angles - Google Patents

Abstract

This invention relates to a trimming and splicing apparatus with adjustable angles, including: a machine bed, a sawing mechanism, a nailing mechanism, a sawing angle adjustment device and a nailing angle adjustment device. The sawing mechanism and nailing mechanism are both provided in the machine bed and located at opposing sides within the machine bed. The sawing angle adjustment device is mounted on the machine bed, for allowing the sawing mechanism to perform sawing operation. The sawing angle adjustment device includes a protractor and a stopping plate pivoted to the protractor. The protractor is provided with plural angle setting holes, into which the blocking plate may be positioned to assume different angular orientation. The frame strips placed in front of the blocking plate may be trimmed by the sawing mechanism into the desired angles. The nailing angle adjustment device is provided on the machine bed, for allowing the nailing mechanism to perform splicing operation. The nailing angle adjustment device includes a bottom plate, a protractor plate, and a clamping plate. The protractor plate and clamping plate are both pivoted to the bottom plate. The protractor plate is provided with plural angle setting holes, into which the clamping plate may be positioned to assume different angular orientation. The clamping plate and the protractor plate form an included angle there between. Two separate frame strips may be placed between the protractor plate and the clamping plate. The nailing mechanism then performs the splicing operation to obtain the desired included angle.
