Description

TECHNICAL FIELD

[0001] The utility model relates to a clamping jig, especially a vertical clamping jig of a circular saw machine which can be conveniently assembled, reduce manufacturing cost and accurately vertically cut. BACKGROUND

[0002] The existing power saw is a handheld rotary cutting machine provided with a toothed disc or a grinding wheel, which cuts and processes a plate by rotating the toothed disc or the grinding wheel. The existing power saw generally includes a handheld circular saw machine and a track type circular saw machine. When the existing handheld circular saw machine is used to vertically cut a plate, an angle ruler must be used to ensure the accuracy and quality of the cutting, so as to ensure that the cutting direction is perpendicular to the plate. When the existing track type circular saw machine is used to vertically cut a plate, an angle ruler cannot be used due to the large size of the track of the existing track type circular saw machine, and a clamping jig must be used to accurately set the track of the existing track type circular saw machine on the plate, so that the cutting direction of the existing track type circular saw machine is perpendicular to the plate during cutting. Further, the existing clamping jig is mostly used by abutting against the side or bottom surface of the track to ensure the position of the track relative to the plate.

[0003] The clamping jig of the existing track type circular saw machine can position the track and ensure the cutting direction. However, the existing clamping jig can only position the track by abutting against the side or bottom surface of the track. However, the single-direction abutting method (side or bottom surface) cannot effectively correct and position the track, which may cause geometric tolerance, affecting the accuracy of the vertical cutting. In order to ensure the accuracy of the cutting, the clamping jig must be repeatedly corrected and positioned, which increases the inconvenience of assembly and the required time. Further, the existing clamping jig needs to be provided with a clamp or a fastener that can clamp the track, and the accuracy of the existing clamping jig needs to be manufactured and controlled by CNC (computer numerical control) processing, which increases the manufacturing cost. Therefore, the existing clamping jig needs to be improved. SUMMARY

[0004] Therefore, to address the problems of existing circular saw clamping fixtures, which cannot effectively correct and position themselves using a single contact direction, easily leading to geometric tolerances that affect the accuracy of vertical cutting, and requiring repeated correction and positioning, thus increasing assembly inconvenience, time, and manufacturing costs, this invention provides a vertical clamping fixture for circular saws.
