Sand valve for water jet cutter cutting machine

Abstract

The invention discloses a sand valve for a water jet cutting machine. The sand valve is characterized by comprising a cutter fixing seat, an inverted L-shaped connecting plate, a water jet cutter fixing frame and a water jet cutter head, an included angle is formed between the rotating axis of the water jet cutter fixing frame and the rotating axis of the inverted L-shaped connecting plate; the sand valve is characterized in that the rotating motor is positioned on one side of the rotating axis of the inverted L-shaped connecting plate; the rotating motor drives the inverted L-shaped connecting plate to rotate through a transmission component; a sand valve body is arranged at the rotating axis of the inverted L-shaped connecting plate; the sand valve body comprises a disc-shaped bin body and an end cover arranged on an upper end opening of the disc-shaped bin body; a transmission shaft is arranged on the axis of the disc-shaped bin body and upwards penetrates through the end cover; theend cover is connected to the cutter fixing seat; the rotating motor drives the transmission shaft to rotate through a transmission component so as to drive the inverted L-shaped connecting plate torotate; a sand inlet in the end cover communicates with a sand source through a transmission pipe; and the sand outlet in the bottom of the disc-shaped bin body communicates with the sand inlet of thewater jet cutter head through a transmission hose. Compared with the prior art, the sand valve has the advantages that high-pressure water can be reliably supplied, and meanwhile the two-dimensionalrotating and swinging amplitude and mode of the water jet cutter head cannot be large.

Description

technical field [0001] The invention relates to a stone or ceramic processing technology. Background technique [0002] As disclosed in patent CN201621010735.3, the existing five-axis water jet cutting machine includes a processing platform, longitudinal guide rails arranged on both sides of the processing platform, a beam driven by power to move forward and backward along the longitudinal guide rail, and a beam driven by power to move along the beam. The left and right moving seats with guide rails moving left and right, the tool fixing seats set on the left and right moving seats and driven by power to move up and down along the vertical guide rails of the left and right moving seats, the L-shaped connecting plates set on the tool fixing seats driven by the rotating motor, The water jet fixed frame driven by the swing motor and the water jet head fixed on the water jet fixed frame are arranged on the L-shaped connecting plate. The rotation axis of the water jet fixed frame...

AI Technical Summary

Problems solved by technology

The cutting principle of waterjet is to use high-pressure water to spray abrasives (such as sand grains) at high speed, and use the high-speed jetted abrasive flow to cut the workpiece. Therefore, high-pressure water and abrasive sources must be supplied to the waterjet head, and the supply The process needs to be completed by the pipeline. The position of the connection between the pipeline and the abrasive source is fixed, while the position of the connection with the water jet head is rotated or swung, which is limited by the setting of the hose, so that the water jet head can be two-dimensional Rotation and swing amplitude and mode are greatly restricted
