Woodwork frame sawing machine

Abstract

The invention discloses a woodwork frame sawing machine. The woodwork frame sawing machine comprises a machine frame and a saw frame, wherein both ends of the saw frame are arranged on the machine frame through two groups of guide mechanisms; the saw frame is connected with a tilting mechanism; each guide mechanism comprises a guide rod and a compensating device; and one end of the guide rod is hinged with the saw frame, while the other end is hinged with the compensating device. The compensating device can compensate longitudinal head drop generated by the transversal reciprocating motion of the saw frame in real time. The woodwork frame sawing machine realizes approximate linear motion during the operation of the saw frame by regulating head drop compensation values of the compensating device. The trajectory of the saw frame motion approximates to that of the conventional saw frame sliding along a linear guide rail and the longitudinal dropping of the idle stroke of the saw frame and the like can be realized. The guide rail and a slide block are not arranged on the woodwork frame sawing machine, so that maintenance cost and using cost are reduced, the problem of frictional heating of the linear guide rail and the slide block is solved, safety is improved, an oil line system for supplying lubricating oil to the slide block and the linear guide rail is saved, the structure of the woodwork frame sawing machine is simplified, and convenient use and simple operation are achieved.

Description

technical field [0001] The invention relates to a woodworking frame saw machine, which belongs to the field of woodworking processing machinery. Background technique [0002] The saw frame of the traditional woodworking frame saw machine is installed on the linear guide rail through the slider. Usually, the gap between the slider and the guide rail is 0.3mm. If the gap is too small, it will be clamped due to heat expansion. It will vibrate, make loud noises, and not function properly. When working, the saw frame is driven by the crankshaft to reciprocate linearly along the linear guide rail for sawing processing. On the one hand, the slider and the linear guide rail are severely worn, and the gap between the slider and the linear guide rail increases after wear. If the wear is small, then Professionals are required to adjust, and maintenance is inconvenient. If the wear is large, the slider or even the linear guide rail needs to be replaced, resulting in an increase in main...

[0002] The saw frame of the traditional woodworking frame saw machine is installed on the linear guide rail through the slider. Usually, the gap between the slider and the guide rail is 0.3mm. If the gap is too small, it will be clamped due to heat expansion. It vibrates, makes loud noises, and doesn't work properly.

When working, the saw frame is driven by the crankshaft to reciprocate linearly along the linear guide rail for sawing processing. On the one hand, the slider and the linear guide rail are severely worn, and the gap between the slider and the linear guide rail increases after wear. If the wear is small, then Professionals are required to adjust, and maintenance is inconvenient. If the wear is large, the slider or even the linear guide rail needs to be replaced, resulting in an increase in maintenance costs. On the other hand, the friction and heat generated by the slider sliding on the linear guide rail are serious. Potential safety hazards, although the existing woodworking frame sawing machine is equipped with an oil circuit system to provide lubricating oil for the slider and linear guide rails, which alleviates the wear and heating problems of the slider and linear guide rails to a certain extent, but this does not prevent Fundamentally solve this problem, and then also increase the problem of adding, replacing lubricating oil and pollution caused by lubricating oil leakage
