Long stroke water knife based on silk pole transmission

Abstract

The invention provides a large-stroke water knife based on a screw rod, and includes a front and a rear longitudinal guide rail racks (1) that are arranged in parallel; the invention is characterized in that the longitudinal guide rail rack (1) includes at least two parts that are connected together or put together, the horizontal upper surface of each part of the longitudinal guide rail rack (1)is provided with a guide rail (2) and each part of the longitudinal guide rail rack (1) is arranged on a respective ball screw rod (3); the two neighboring ball screw rods (3) are parallel with each other and has an overlapping zone B with the length no less than the width L of a sliding plate (4); each ball screw rod (3) has a respective nut (5), which is connected with the corresponding slidingplate (4), each side of the two sides of the sliding plate (4) is connected with a sliding block (6), which is flexibly arranged on the corresponding guide rail (2); a labyrinth sealing device (10) is arranged on the guide rail (2); screw rod bracing frames (11) used for supporting the ball screw rod (3) so as to prevent the ball screw rod from sinking due to the gravity are arranged between the longitudinal guide rail rack (1) at intervals. The invention realizes the enlargement of the stroke length of the water knife through a building block combination mode and has the advantages of high precision and strong processing capacity.

Description

technical field [0001] The invention relates to a water jet, in particular to a large-stroke water jet, in particular to a large-stroke water jet based on screw drive. Background technique [0002] At present, waterjet cutting equipment is more and more favored by all walks of life because of its unique performance, and it is developing in the direction of large-scale and multi-functional. [0003] As we all know, when the longitudinal stroke of the waterjet equipment is greater than 4 meters, the traditional screw drive structure will generate large vibrations during the rotation of the screw due to the influence of the weight of the screw, and its precision operation cannot be guaranteed. Therefore, when When the longitudinal stroke is more than 4 meters, if the screw drive is still used, in order to prevent deformation, the diameter of the screw will become larger, and the processing cost and difficulty will also become quite large, especially when the length of a single ...
