Embodiment Construction

[0028] Next, specific embodiments of the present invention will be described with reference to the drawings.

[0029] figure 1 It is a left side view of a desktop circular saw as an example of a cutting machine. In the desktop circular saw 1, a turntable 3 capable of horizontal rotation is placed on a base 2. The height of the upper surface of the turntable 3 is the same as that of the base 2. The same height of the upper surface, at the rear end of turntable 3 (with figure 1 The right side of the paper in the middle is the front) erectly provided with a support arm 4 that can rotate around the axis in the front-rear direction, and at the upper end of the support arm 4, a rotatable main body 5 is installed through a fulcrum 6 in the left-right direction. However, in the normal state due to being arranged on the torsion spring 7 on the fulcrum 6 (refer to Figure 4 ) of the force, the main body 5 is in the figure 1 upper limit position shown. 8 denotes a guide baffle, and t...

Abstract

The present invention provides a cutting machine capable of obtaining high cutting capacity with a simple structure that can maintain a compact structure and low cost. On the desktop circular saw machine, the cutting unit (U) from the motor (12) to the saw blade (16) is separated from the main body (5) structure in the main body (5), in addition, the cutting unit (U) is separated from the main body (5) The lower limit position of (5) is held in the main body (5) so as to be able to swing forward and backward. Therefore, the cutting width can be enlarged by a simple structure of only swinging the cutting unit (U) without sliding the entire body (5) in the front-rear direction.

Description

technical field [0001] The invention relates to a cutting machine such as a desktop circular saw. Background technique [0002] In a cutting machine such as a desktop circular saw machine, a main body capable of moving up and down is provided on a base on which a workpiece is placed. The main body has a cutting blade driven by a motor to rotate. The workpiece is cut (for example, Patent Document 1). [0003] The cutting capability of such a cutting machine (dimensions (cutting width) in the front-rear direction of the cuttable workpiece that can be cut) is determined by the diameter of the cutting blade. Therefore, as a cutting machine that can cut a workpiece with a large cutting width, For example, a cutting machine such as a sliding circular saw disclosed in Patent Document 2 is known in which the main body of the cutting machine can slide forward and backward. [0004] [Patent Document 1] Japanese Invention Patent Laid-Open Publication No. 8-332605 [0005] [Patent Do...
