Self-locking hydraulic sliding platform

Abstract

The invention provides a self-locking hydraulic sliding platform capable of precisely positioning lengthways as well as precisely positioning in a vertical direction. The self-locking hydraulic sliding platform is simply improved based on prior hydraulic sliding platforms, and performs reliable positioning to obviously improve the quality of processed tools. The self-locking hydraulic sliding platform comprises a slideway body, a sliding operating platform in longitudinal sliding movement along the slideway body, and an oil cylinder for driving the sliding operating platform to move, wherein an adjusting plate is arranged on the sliding operating platform; a fixing plate is arranged on the slideway body; two faces of the fixing plate opposite to the adjusting plate are two matching inclined faces; when the sliding operating platform is driven to move by the oil cylinder, the fixing plate is in contact with two inclined faces on the adjusting plate, and a downward acting force is applied to the adjusting plate through the inclined faces of the fixing plate.

Description

technical field [0001] The technology belongs to the field of metal cutting combined machine tools and relates to a self-locking hydraulic slide table. Background technique [0002] The main function of the hydraulic slide table is to cooperate with other functional components in the cutting combination machine tool, such as boring head, milling head, etc. to complete the cutting process of metal products. In the process of processing, it is often necessary for the hydraulic slide table to stop precisely at a certain position. The existing hydraulic slide table comprises a guide rail body 1, a sliding table 2 that slides longitudinally along the guide rail body, and an oil cylinder 3 that drives the sliding table to move (see figure 1 ), the sliding table 2 is slidably arranged on the inverted V-shaped guide rail 11 extending longitudinally along the guide rail body, and the guide rail body 1 is provided with a screw rod 4 that can adjust the axial position. For a long tim...

AI Technical Summary

Problems solved by technology

At this time, only the axial direction (longitudinal direction) of the oil cylinder is used to complete the positioning and tightening, while in the vertical direction perpendicular to the axis of the oil cylinder, due to a certain gap between the sliding worktable and the guide rail working surface of the guide rail body, the locking is not done, and the cutting head is working. Drive the worktable of the hydraulic slide table to vibrate up and down, thus affecting the quality of the processed workpiece

The previous solution was to add another set of hydraulic or mechanical devices to lock the vertical surface, but this not only affects the processing efficiency, but also increases the equipment investment cost
