Carpenter saw

Abstract

The invention relates to a carpenter saw which comprises a power supply box, a bracket and a working platform, wherein, the power supply box is internally provided with a motor, the right end of the power supply box is provided with a saw bit driven by the motor, one end of the bracket is connected with the right end of the power supply box in an inserting way, the upper end of the bracket is provided with at least two sliding rods which are arranged in parallel along the longitudinal direction by a support seat, each of the sliding rods is sheathed and connected with at least two sliding linear bearings, and the working platform is fixedly installed on the linear bearings; when the working platform slides, the linear bearings move along with the working platform in real time, so that the good matching between the linear bearings and the sliding rods can be ensured when in sliding, the vibration can be effectively reduced, and the processing quality of wood can be improved; in addition, the linear bearings can be directly used for limiting the movement of the working platform along the vertical direction and need not to be in virtue of other structures. Therefore, the carpenter saw is very simple in structure and convenient in installation and maintenance.

Description

Technical field: [0001] The invention relates to a woodworking saw for processing wood. Background technique: [0002] In the prior art, as disclosed in Chinese patent 200510016346.1, a panel saw workbench for woodworking includes a fixed base, a sliding workbench, rollers and polished rod bearings. One side of the above-mentioned roller is a single roller, and the other side is a double roller. The two ends of the rollers are respectively provided with grooves corresponding to the fixed seat and the sliding table. The rollers are embedded between the fixed base and the sliding table. Polished rod bearings are installed in the groove between the base and the sliding table and the single roller, polished rod bearings are installed in the groove between the fixed base and the double rollers, and the other groove between the sliding table and the double rollers Polished rod bearings are installed inside. When this structure is in use, the workbench uses the cooperation of poli...

AI Technical Summary

Problems solved by technology

[0003] First, in this structure, since the roller is fixed on the mandrel, it cannot move axially with the workbench and the polished rod bearing, and in the assembly process, there must be a certain matching error between the polished rod bearing and the roller, which means It will cause the table to easily generate large vibration during sliding, thus reducing the quality of wood processing;

[0004] Second, in this structure, the horizontal sliding of the workbench is realized through the cooperation of the polished rod bearing and the rollers, and the binding force in the vertical direction of the workbench needs to be realized by a special restraint mechanism. The structure is very complicated, and maintenance and installation are difficult
