Saw bow free from dismounting and displacing and saw blade connecting gripping heads thereof

Abstract

The invention discloses a saw bow free from dismounting and displacing and saw blade connecting gripping heads thereof. The saw bow comprises a bow rack and the saw blade connecting gripping heads respectively installed at left and right end parts of the bow rack, wherein each saw blade connecting gripping head comprises a gripping head body; a mounting section connected with the corresponding end part of the bow rack is fixedly arranged at the outer end of a fixing barrel of the gripping head body; a core shaft which can rotate around the axis of the fixing barrel is axially inserted in the fixing barrel in an anti-dropping way; a displacing stopping fit section is arranged on the core shaft; the inner end of the core shaft extends out of the fixing barrel; a radial extending saw blade hooking pin is formed on the extending part of the core shaft; a gear switch mechanism which can axially reciprocate along the fixing barrel is arranged on the outer peripheral surface of the fixing barrel; and the gear switch mechanism and the displacing stopping fit section of the core shaft can select locking matching to ensure that the core shaft stops displacing or select unlocking matching to ensure that the core shaft rotates. When the saw blade connecting gripping heads of the saw bow are used for sawing parts, the position of a saw blade on the bow rack can be adjusted according to requirements of the machined parts, so that the position of the saw blade can be adjusted rapidly under different operating states.

Description

technical field [0001] The invention relates to a saw bow. Background technique [0002] The saw bow is a tool used to install and tension the saw blade. The more common ones are fixed type and adjustable type. No matter which method is used, the structure of the bow frame is basically adopted. One end of the bow frame is equipped with a fixed chuck and the other. There is a movable chuck at one end, and the two chucks are respectively inserted into the end of the bow frame through their respective square mortises. A saw blade coupling pin is respectively arranged at the opposite end of the two chucks, and the saw blade is connected by the two ends. The hole is hung between the two saw blade hook pins, and a screw rod is fixed on the square tenon of the movable chuck, and a wing nut is threaded on the screw rod, and the tension of the saw blade can be realized by relying on the wing nut. During the sawing process of the saw blade, according to different situations, the saw ...
