Technical field
The utility model relates to a kind of Profile cut-off machine, particularly a kind of safety guard that can ensure the Profile cut-off machine of cutting process safe operation.
Background technology
Profile cut-off machine is a kind of cutting tool being widely used in the section bars such as the various steel of cutting processing, aluminium section bar, and during operation, operator is positioned at the front of grinding wheel, and grinding wheel rotates from front to back.In order to ensure use safety in cutting process, the Profile cut-off machine of prior art generally arranges semi-surrounding protective roof structure above grinding wheel.Profile cut-off machine due to semi-surrounding protective roof structure also has the cutting blade of non-cutting outside exposed in cutting process, directly affects personal safety during operator's operation, still there is certain potential safety hazard.For this reason, many manufacturers and knowledgeable people develop for the problems referred to above and manufacture experimently, but not yet find comparatively reasonably product to emerge so far.
Summary of the invention
In order to the above-mentioned defect that the Profile cut-off machine overcoming existing semi-surrounding protective roof structure exists, the purpose of this utility model is to provide a kind of simple and reasonable, flexible and convenient operation, safe and reliable and can the Profile cut-off machine safety guard of self-locking.
The utility model solves the technical scheme that its technical problem adopts, it comprises support, clamp system, nose assembly, secure shroud, movable shield, nose assembly is rotatably connected on support by torsion spring, secure shroud is fixed on nose assembly, described movable shield is arranged on rotationally on nose assembly and also can rotates in secure shroud, link gear is provided with between support and movable shield, link gear comprises the stationary links be fixed on support, movable rod, movable rod one end is hinged in stationary links, the other end is hinged in movable shield through the opening of secure shroud.
The further scheme of the utility model, described secure shroud is provided with self-locking mechanism, self-locking mechanism comprises guard shield self-lock rod, self-locking rotation seat, self-locking rotation seat is fixed in secure shroud, guard shield self-lock rod is hinged on self-locking rotation seat by rotating shaft and rotating shaft torsion spring, one end of guard shield self-lock rod is provided with rotates handle, blocks the upper limit flange of movable shield in the lockhole that the other end stretches into secure shroud.
The further scheme of the utility model, the bottom of described movable shield is provided with the lower limit flange matched with secure shroud.
After adopting said structure, there are following advantage and effect compared with the prior art: one is also can rotate in secure shroud because movable shield is arranged on nose assembly rotationally, movable rod one end is hinged in stationary links, the other end is hinged in movable shield through the opening of secure shroud, pressing down in nose assembly cutting process, under movable rod pulls, movable shield bottom is opened gradually, after having cut, under torsion spring effect, nose assembly and secure shroud automatically reset, movable shield automatically resets and encases grinding wheel under movable rod effect, thus reach the object of safe handling.Two is because secure shroud is provided with self-locking mechanism, only inwardly pressing the rotation handle of guard shield self-lock rod, the other end of guard shield self-lock rod tilts and is separated unblock with the upper limit flange of movable shield, and could press handle strip and move nose assembly and carry out cutting work, guarantee misoperation can not occur.
