Problems solved by technology

This method will produce positioning gaps, poor positioning accuracy of the workpiece, manual pre-positioning is required during operation, and the tooling only completes the fixed clamping work, the manual labor intensity is high, and the production efficiency is low. Some workpieces are also adsorbed and clamped by secondary pneumatics. , improve the clamping work, but the pneumatic clamping is prone to air leakage when the workpiece size is different, resulting in unstable clamping

Abstract

The invention discloses a four-axis hydraulic locking device for a vertical machining center. The four-axis hydraulic locking device structurally comprises a four-axis numerical control device, a four-axis hydraulic device, lifting rings, a clamping device, a four-axis tailstock, and a base, wherein the clamping device comprises a worktable, a pneumatic control valve, a positioning seal mechanism,an air pipe and turning cylinders; the clamping device improves the pneumatic clamping of workpieces through the positioning seal mechanism; the condition that when the sizes of the workpieces are different, the leakage is caused, resulting in unstable clamping, influence on the positioning precision of the workpieces and scrapping of the workpieces is avoided; the four-axis tailstock is insertedinto an internal gear ring groove by a locking mechanism to enable a rotary chuck to control the worktable to be positioned for operation, so that the phenomenon the occurrence of positioning gaps results in low workpiece positioning precision is avoided; and through the design, the labor intensity is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of hydraulic equipment, in particular to a four-axis hydraulic locking equipment for a vertical machining center. Background technique [0002] With the development of mechanical processing, the clamping workpiece needs to be convenient to use, precise clamping and positioning, time-saving, multi-purpose, versatile, safe and efficient, etc. Tooling in machining is one of the important components in the machinery industry. [0003] At present, most manufacturers will choose four-axis hydraulic fixtures, but traditional hydraulic fixtures generally use positioning pins directly when positioning workpieces. After manually determining the position of the workpiece, the positioning pins are extended from the fixture and inserted into the workpiece holes to fix the position of the workpiece. Effect. This method will produce positioning gaps, poor positioning accuracy of the workpiece, manual pre-positioning is required dur...
