Abstract: The present invention provides a saw blade dismantling & positioning structure of sawing machine, whereby the push rod is snapped into the hole of the saw blade shaft disk for controlling the positioning of the rotating shaft and rapid dismantling the saw blade; a shaft disk is mounted onto the rotating shaft of the sawing machine, and at least a hole is preset laterally onto the shaft disk; a positioning device is assembled onto the lifting seat at the same side of the shaft disk; the pressure plate of the positioning device is driven so that the push rod is coupled and snapped into the hole of the shaft disk for controlling the positioning of rotating shaft, and rapid dismantling or assembly of the saw blade.

Abstract: The present invention provides a quick dismantling and positioning structure for the saw blade of sawing machine; a n-shaped rod is defined, two guard plates and stoppers are correspondingly arranged at both sides to form a shield assembly; moreover, two moveable dampers are arranged within the rod, a quick-release bolt is externally mounted onto the front end of the moveable clamper, so that the shield assembly could be quickly dismantled or reassembled by screwing and release of the quick-release bolt.

Abstract: The invention provides a positioning device for a saw blade elevating platform of a wood sawing machine. More specifically, when a transmission base for controlling a saw blade to elevate in the wood sawing machine is elevated to and positioned at a predetermined position, a predetermined pressing bar disposed in a guiding seat of a mounting seat, at which the elevating platform is located, is pressed by external screws to force the elevating platform to be positioned at a set position. Thus, the saw blade, which is rotated at the high rotating speed and is applied with a high reaction force, can be held absolutely stable, and the operating stability and the precision can be greatly enhanced.

Abstract: A guiding and pressing device for a belt sander includes two triangular guiding blocks or sheet-like inclined guiding blocks, which are disposed at suitable positions on a front side frame of the sander and near to a circulating path of a sand belt. The two guiding blocks have opposite inclined surfaces near an edge of the sand belt to restrict the circulating path of the sand belt without damaging the edge of the sand belt. In addition, an elastic pressing or push rod is disposed inside the sand belt and on a backside of the frame in order to frequently push the sand belt outwards and thus to keep the sand belt in a tightened state when the belt sander is sanding.

Abstract: A belt sander includes a base, a sanding device, a worktable, a tipping drive device, and a swinging device. The swinging device includes a cylindrical roller, a central shaft, a toothed ring, a drive gear, a cam, and a fixing rod. The swinging device drives the sanding device to produce a slightly reciprocally swinging action during operation of the sanding device. Thus, the grinding path and area of the sand belt are increased largely by the reciprocally and successively swinging action of the swinging device and the sanding device, so that the sand belt can be used to grind the wooden material exactly and efficiently, thereby greatly enhancing the grinding and finishing effect of the belt sander.
